Unless you need to communicate with Zope 2 APIs, you're probably better off using Python's bult-in datetime module. Home-page: http://pypi.python.org/pypi/DateTime Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: The DateTime package ==================== Encapsulation of date/time values. Function Timezones() -------------------- Returns the list of recognized timezone names: >>> from DateTime import Timezones >>> zones = set(Timezones()) Almost all of the standard pytz timezones are included, with the exception of some commonly-used but ambiguous abbreviations, where historical Zope usage conflicts with the name used by pytz: >>> import pytz >>> [x for x in pytz.all_timezones if x not in zones] ['CET', 'EET', 'EST', 'MET', 'MST', 'WET'] Class DateTime -------------- DateTime objects represent instants in time and provide interfaces for controlling its representation without affecting the absolute value of the object. DateTime objects may be created from a wide variety of string or numeric data, or may be computed from other DateTime objects. DateTimes support the ability to convert their representations to many major timezones, as well as the ablility to create a DateTime object in the context of a given timezone. DateTime objects provide partial numerical behavior: * Two date-time objects can be subtracted to obtain a time, in days between the two. * A date-time object and a positive or negative number may be added to obtain a new date-time object that is the given number of days later than the input date-time object. * A positive or negative number and a date-time object may be added to obtain a new date-time object that is the given number of days later than the input date-time object. * A positive or negative number may be subtracted from a date-time object to obtain a new date-time object that is the given number of days earlier than the input date-time object. DateTime objects may be converted to integer, long, or float numbers of days since January 1, 1901, using the standard int, long, and float functions (Compatibility Note: int, long and float return the number of days since 1901 in GMT rather than local machine timezone). DateTime objects also provide access to their value in a float format usable with the python time module, provided that the value of the object falls in the range of the epoch-based time module. A DateTime object should be considered immutable; all conversion and numeric operations return a new DateTime object rather than modify the current object. A DateTime object always maintains its value as an absolute UTC time, and is represented in the context of some timezone based on the arguments used to create the object. A DateTime object's methods return values based on the timezone context. Note that in all cases the local machine timezone is used for representation if no timezone is specified. Constructor for DateTime ------------------------ DateTime() returns a new date-time object. DateTimes may be created with from zero to seven arguments: * If the function is called with no arguments, then the current date/ time is returned, represented in the timezone of the local machine. * If the function is invoked with a single string argument which is a recognized timezone name, an object representing the current time is returned, represented in the specified timezone. * If the function is invoked with a single string argument representing a valid date/time, an object representing that date/ time will be returned. As a general rule, any date-time representation that is recognized and unambigous to a resident of North America is acceptable. (The reason for this qualification is that in North America, a date like: 2/1/1994 is interpreted as February 1, 1994, while in some parts of the world, it is interpreted as January 2, 1994.) A date/ time string consists of two components, a date component and an optional time component, separated by one or more spaces. If the time component is omited, 12:00am is assumed. Any recognized timezone name specified as the final element of the date/time string will be used for computing the date/time value. (If you create a DateTime with the string "Mar 9, 1997 1:45pm US/Pacific", the value will essentially be the same as if you had captured time.time() at the specified date and time on a machine in that timezone). o Returns current date/time, represented in US/Eastern: >>> from DateTime import DateTime >>> e = DateTime('US/Eastern') >>> e.timezone() 'US/Eastern' o Returns specified time, represented in local machine zone: >>> x = DateTime('1997/3/9 1:45pm') >>> x.parts() # doctest: +ELLIPSIS (1997, 3, 9, 13, 45, 0.0, ...) o Specified time in local machine zone, verbose format: >>> y = DateTime('Mar 9, 1997 13:45:00') >>> y.parts() # doctest: +ELLIPSIS (1997, 3, 9, 13, 45, 0.0, ...) >>> y == x True The date component consists of year, month, and day values. The year value must be a one-, two-, or four-digit integer. If a one- or two-digit year is used, the year is assumed to be in the twentieth century. The month may an integer, from 1 to 12, a month name, or a month abreviation, where a period may optionally follow the abreviation. The day must be an integer from 1 to the number of days in the month. The year, month, and day values may be separated by periods, hyphens, forward, shashes, or spaces. Extra spaces are permitted around the delimiters. Year, month, and day values may be given in any order as long as it is possible to distinguish the components. If all three components are numbers that are less than 13, then a a month-day-year ordering is assumed. The time component consists of hour, minute, and second values separated by colons. The hour value must be an integer between 0 and 23 inclusively. The minute value must be an integer between 0 and 59 inclusively. The second value may be an integer value between 0 and 59.999 inclusively. The second value or both the minute and second values may be ommitted. The time may be followed by am or pm in upper or lower case, in which case a 12-hour clock is assumed. * If the DateTime function is invoked with a single Numeric argument, the number is assumed to be either a floating point value such as that returned by time.time() , or a number of days after January 1, 1901 00:00:00 UTC. A DateTime object is returned that represents either the gmt value of the time.time() float represented in the local machine's timezone, or that number of days after January 1, 1901. Note that the number of days after 1901 need to be expressed from the viewpoint of the local machine's timezone. A negative argument will yield a date-time value before 1901. * If the function is invoked with two numeric arguments, then the first is taken to be an integer year and the second argument is taken to be an offset in days from the beginning of the year, in the context of the local machine timezone. The date-time value returned is the given offset number of days from the beginning of the given year, represented in the timezone of the local machine. The offset may be positive or negative. Two-digit years are assumed to be in the twentieth century. * If the function is invoked with two arguments, the first a float representing a number of seconds past the epoch in gmt (such as those returned by time.time()) and the second a string naming a recognized timezone, a DateTime with a value of that gmt time will be returned, represented in the given timezone. >>> import time >>> t = time.time() Time t represented as US/Eastern: >>> now_east = DateTime(t, 'US/Eastern') Time t represented as US/Pacific: >>> now_west = DateTime(t, 'US/Pacific') Only their representations are different: >>> now_east == now_west True * If the function is invoked with three or more numeric arguments, then the first is taken to be an integer year, the second is taken to be an integer month, and the third is taken to be an integer day. If the combination of values is not valid, then a DateTimeError is raised. One- or two-digit years up to 69 are assumed to be in the 21st century, whereas values 70-99 are assumed to be 20th century. The fourth, fifth, and sixth arguments are floating point, positive or negative offsets in units of hours, minutes, and days, and default to zero if not given. An optional string may be given as the final argument to indicate timezone (the effect of this is as if you had taken the value of time.time() at that time on a machine in the specified timezone). If a string argument passed to the DateTime constructor cannot be parsed, it will raise DateTime.SyntaxError. Invalid date, time, or timezone components will raise a DateTime.DateTimeError. The module function Timezones() will return a list of the timezones recognized by the DateTime module. Recognition of timezone names is case-insensitive. Instance Methods for DateTime (IDateTime interface) --------------------------------------------------- Conversion and comparison methods ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ``timeTime()`` returns the date/time as a floating-point number in UTC, in the format used by the python time module. Note that it is possible to create date /time values with DateTime that have no meaningful value to the time module, and in such cases a DateTimeError is raised. A DateTime object's value must generally be between Jan 1, 1970 (or your local machine epoch) and Jan 2038 to produce a valid time.time() style value. >>> dt = DateTime('Mar 9, 1997 13:45:00 US/Eastern') >>> dt.timeTime() 857933100.0 >>> DateTime('2040/01/01 UTC').timeTime() 2208988800.0 >>> DateTime('1900/01/01 UTC').timeTime() -2208988800.0 * ``toZone(z)`` returns a DateTime with the value as the current object, represented in the indicated timezone: >>> dt.toZone('UTC') DateTime('1997/03/09 18:45:00 UTC') >>> dt.toZone('UTC') == dt True * ``isFuture()`` returns true if this object represents a date/time later than the time of the call: >>> dt.isFuture() False >>> DateTime('Jan 1 3000').isFuture() # not time-machine safe!

General formats from previous DateTime ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ``Date()`` return the date string for the object: >>> dt.Date() '1997/03/09' * ``Time()`` returns the time string for an object to the nearest second: >>> dt.Time() '13:45:00' * ``TimeMinutes()`` returns the time string for an object not showing seconds: >>> dt.TimeMinutes() '13:45' * ``AMPM()`` returns the time string for an object to the nearest second: >>> dt.AMPM() '01:45:00 pm' * ``AMPMMinutes()`` returns the time string for an object not showing seconds: >>> dt.AMPMMinutes() '01:45 pm' * ``PreciseTime()`` returns the time string for the object: >>> dt.PreciseTime() '13:45:00.000' * ``PreciseAMPM()`` returns the time string for the object: >>> dt.PreciseAMPM() '01:45:00.000 pm' * ``yy()`` returns the calendar year as a 2 digit string >>> dt.yy() '97' * ``mm()`` returns the month as a 2 digit string >>> dt.mm() '03' * ``dd()`` returns the day as a 2 digit string: >>> dt.dd() '09' * ``rfc822()`` returns the date in RFC 822 format: >>> dt.rfc822() 'Sun, 09 Mar 1997 13:45:00 -0500' New formats ~~~~~~~~~~~ * ``fCommon()`` returns a string representing the object's value in the format: March 9, 1997 1:45 pm: >>> dt.fCommon() 'March 9, 1997 1:45 pm' * ``fCommonZ()`` returns a string representing the object's value in the format: March 9, 1997 1:45 pm US/Eastern: >>> dt.fCommonZ() 'March 9, 1997 1:45 pm US/Eastern' * ``aCommon()`` returns a string representing the object's value in the format: Mar 9, 1997 1:45 pm: >>> dt.aCommon() 'Mar 9, 1997 1:45 pm' * ``aCommonZ()`` return a string representing the object's value in the format: Mar 9, 1997 1:45 pm US/Eastern: >>> dt.aCommonZ() 'Mar 9, 1997 1:45 pm US/Eastern' * ``pCommon()`` returns a string representing the object's value in the format Mar. 9, 1997 1:45 pm: >>> dt.pCommon() 'Mar. 9, 1997 1:45 pm' * ``pCommonZ()`` returns a string representing the object's value in the format: Mar. 9, 1997 1:45 pm US/Eastern: >>> dt.pCommonZ() 'Mar. 9, 1997 1:45 pm US/Eastern' * ``ISO()`` returns a string with the date/time in ISO format. Note: this is not ISO 8601-format! See the ISO8601 and HTML4 methods below for ISO 8601-compliant output. Dates are output as: YYYY-MM-DD HH:MM:SS >>> dt.ISO() '1997-03-09 13:45:00' * ``ISO8601()`` returns the object in ISO 8601-compatible format containing the date, time with seconds-precision and the time zone identifier - see http://www.w3.org/TR/NOTE-datetime. Dates are output as: YYYY-MM-DDTHH:MM:SSTZD (T is a literal character, TZD is Time Zone Designator, format +HH:MM or -HH:MM). The ``HTML4()`` method below offers the same formatting, but converts to UTC before returning the value and sets the TZD"Z" >>> dt.ISO8601() '1997-03-09T13:45:00-05:00' * ``HTML4()`` returns the object in the format used in the HTML4.0 specification, one of the standard forms in ISO8601.

NOTE: __cmp__ support is provided for backward compatibility only, and mixing DateTimes with ExtensionClasses could cause __cmp__ to break. You should use the methods lessThan, greaterThan, lessThanEqualTo, greaterThanEqualTo, equalTo and notEqualTo to avoid potential problems later! >>> cmp(dt, dt) 0 >>> cmp(dt, dt.toZone('UTC')) 0 >>> cmp(dt, dt.timeTime()) 0 >>> cmp(dt, DateTime('2000/01/01')) -1 >>> cmp(dt, DateTime('1900/01/01')) 1 DateTime objects can be compared to other DateTime objects OR floating point numbers such as the ones which are returned by the python time module.

DateTime instances constructed under version 3 can be read and unpickled by this version. The pickled data is converted to the current versions format (old-style class / no slots). Once converted it will be stored again in the old format. This should allow for a transparent upgrade/downgrade path between DateTime 2 and 3. 2.12.6 (2010-10-17) ------------------- - Changed ``testDayOfWeek`` test to be independent of OS locale. 2.12.5 (2010-07-29) ------------------- - Launchpad #143269: Corrected the documentation for year value behavior when constructing a DateTime object with three numeric arguments. - Launchpad #142521: Removed confusing special case in DateTime.__str__ where DateTime instances for midnight (e.g. '2010-07-27 00:00:00 US/Eastern') values would render only their date and nothing else. 2.12.4 (2010-07-12) ------------------- - Fixed mapping of EDT (was -> 'GMT-0400', now 'GMT-4'). 2.12.3 (2010-07-09) ------------------- - Added EDT timezone support. Addresses bug #599856. [vangheem] 2.12.2 (2010-05-05) ------------------- - Launchpad #572715: Relaxed pin on pytz, after applying a patch from Marius Gedminus which fixes the apparent API breakage. 2.12.1 (2010-04-30) ------------------- - Removed an undeclared testing dependency on zope.testing.doctest in favor of the standard libraries doctest module. - Added a maximum version requirement on pytz <= 2010b. Later versions produce test failures related to timezone changes. 2.12.0 (2009-03-04) ------------------- - Launchpad #290254: Forward-ported fix for '_micros'-less pickles from the Zope 2.11 branch version. 2.11.2 (2009-02-02) ------------------- - Include *all* pytz zone names, not just "common" ones. - Fix one fragile doctest, band-aid another. - Fix for launchpad #267545: DateTime(DateTime()) should preserve the correct hour. 2.11.1 (2008-08-05) ------------------- - DateTime conversion of datetime objects with non-pytz tzinfo. Timezones() returns a copy of the timezone list (allows tests to run). - Merged the slinkp-datetime-200007 branch: fix the DateTime(anotherDateTime) constructor to preserve timezones. 2.11.0b1 (2008-01-06) --------------------- - Split off from the Zope2 main source code tree.

Unless you need to communicate with Zope 2 APIs, you're probably better off using Python's bult-in datetime module. Home-page: http://pypi.python.org/pypi/DateTime Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: The DateTime package ==================== Encapsulation of date/time values. Function Timezones() -------------------- Returns the list of recognized timezone names: >>> from DateTime import Timezones >>> zones = set(Timezones()) Almost all of the standard pytz timezones are included, with the exception of some commonly-used but ambiguous abbreviations, where historical Zope usage conflicts with the name used by pytz: >>> import pytz >>> [x for x in pytz.all_timezones if x not in zones] ['CET', 'EET', 'EST', 'MET', 'MST', 'WET'] Class DateTime -------------- DateTime objects represent instants in time and provide interfaces for controlling its representation without affecting the absolute value of the object. DateTime objects may be created from a wide variety of string or numeric data, or may be computed from other DateTime objects. DateTimes support the ability to convert their representations to many major timezones, as well as the ablility to create a DateTime object in the context of a given timezone. DateTime objects provide partial numerical behavior: * Two date-time objects can be subtracted to obtain a time, in days between the two. * A date-time object and a positive or negative number may be added to obtain a new date-time object that is the given number of days later than the input date-time object. * A positive or negative number and a date-time object may be added to obtain a new date-time object that is the given number of days later than the input date-time object. * A positive or negative number may be subtracted from a date-time object to obtain a new date-time object that is the given number of days earlier than the input date-time object. DateTime objects may be converted to integer, long, or float numbers of days since January 1, 1901, using the standard int, long, and float functions (Compatibility Note: int, long and float return the number of days since 1901 in GMT rather than local machine timezone). DateTime objects also provide access to their value in a float format usable with the python time module, provided that the value of the object falls in the range of the epoch-based time module. A DateTime object should be considered immutable; all conversion and numeric operations return a new DateTime object rather than modify the current object. A DateTime object always maintains its value as an absolute UTC time, and is represented in the context of some timezone based on the arguments used to create the object. A DateTime object's methods return values based on the timezone context. Note that in all cases the local machine timezone is used for representation if no timezone is specified. Constructor for DateTime ------------------------ DateTime() returns a new date-time object. DateTimes may be created with from zero to seven arguments: * If the function is called with no arguments, then the current date/ time is returned, represented in the timezone of the local machine. * If the function is invoked with a single string argument which is a recognized timezone name, an object representing the current time is returned, represented in the specified timezone. * If the function is invoked with a single string argument representing a valid date/time, an object representing that date/ time will be returned. As a general rule, any date-time representation that is recognized and unambigous to a resident of North America is acceptable. (The reason for this qualification is that in North America, a date like: 2/1/1994 is interpreted as February 1, 1994, while in some parts of the world, it is interpreted as January 2, 1994.) A date/ time string consists of two components, a date component and an optional time component, separated by one or more spaces. If the time component is omited, 12:00am is assumed. Any recognized timezone name specified as the final element of the date/time string will be used for computing the date/time value. (If you create a DateTime with the string "Mar 9, 1997 1:45pm US/Pacific", the value will essentially be the same as if you had captured time.time() at the specified date and time on a machine in that timezone). o Returns current date/time, represented in US/Eastern: >>> from DateTime import DateTime >>> e = DateTime('US/Eastern') >>> e.timezone() 'US/Eastern' o Returns specified time, represented in local machine zone: >>> x = DateTime('1997/3/9 1:45pm') >>> x.parts() # doctest: +ELLIPSIS (1997, 3, 9, 13, 45, 0.0, ...) o Specified time in local machine zone, verbose format: >>> y = DateTime('Mar 9, 1997 13:45:00') >>> y.parts() # doctest: +ELLIPSIS (1997, 3, 9, 13, 45, 0.0, ...) >>> y == x True The date component consists of year, month, and day values. The year value must be a one-, two-, or four-digit integer. If a one- or two-digit year is used, the year is assumed to be in the twentieth century. The month may an integer, from 1 to 12, a month name, or a month abreviation, where a period may optionally follow the abreviation. The day must be an integer from 1 to the number of days in the month. The year, month, and day values may be separated by periods, hyphens, forward, shashes, or spaces. Extra spaces are permitted around the delimiters. Year, month, and day values may be given in any order as long as it is possible to distinguish the components. If all three components are numbers that are less than 13, then a a month-day-year ordering is assumed. The time component consists of hour, minute, and second values separated by colons. The hour value must be an integer between 0 and 23 inclusively. The minute value must be an integer between 0 and 59 inclusively. The second value may be an integer value between 0 and 59.999 inclusively. The second value or both the minute and second values may be ommitted. The time may be followed by am or pm in upper or lower case, in which case a 12-hour clock is assumed. * If the DateTime function is invoked with a single Numeric argument, the number is assumed to be either a floating point value such as that returned by time.time() , or a number of days after January 1, 1901 00:00:00 UTC. A DateTime object is returned that represents either the gmt value of the time.time() float represented in the local machine's timezone, or that number of days after January 1, 1901. Note that the number of days after 1901 need to be expressed from the viewpoint of the local machine's timezone. A negative argument will yield a date-time value before 1901. * If the function is invoked with two numeric arguments, then the first is taken to be an integer year and the second argument is taken to be an offset in days from the beginning of the year, in the context of the local machine timezone. The date-time value returned is the given offset number of days from the beginning of the given year, represented in the timezone of the local machine. The offset may be positive or negative. Two-digit years are assumed to be in the twentieth century. * If the function is invoked with two arguments, the first a float representing a number of seconds past the epoch in gmt (such as those returned by time.time()) and the second a string naming a recognized timezone, a DateTime with a value of that gmt time will be returned, represented in the given timezone. >>> import time >>> t = time.time() Time t represented as US/Eastern: >>> now_east = DateTime(t, 'US/Eastern') Time t represented as US/Pacific: >>> now_west = DateTime(t, 'US/Pacific') Only their representations are different: >>> now_east == now_west True * If the function is invoked with three or more numeric arguments, then the first is taken to be an integer year, the second is taken to be an integer month, and the third is taken to be an integer day. If the combination of values is not valid, then a DateTimeError is raised. One- or two-digit years up to 69 are assumed to be in the 21st century, whereas values 70-99 are assumed to be 20th century. The fourth, fifth, and sixth arguments are floating point, positive or negative offsets in units of hours, minutes, and days, and default to zero if not given. An optional string may be given as the final argument to indicate timezone (the effect of this is as if you had taken the value of time.time() at that time on a machine in the specified timezone). If a string argument passed to the DateTime constructor cannot be parsed, it will raise DateTime.SyntaxError. Invalid date, time, or timezone components will raise a DateTime.DateTimeError. The module function Timezones() will return a list of the timezones recognized by the DateTime module. Recognition of timezone names is case-insensitive. Instance Methods for DateTime (IDateTime interface) --------------------------------------------------- Conversion and comparison methods ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ``timeTime()`` returns the date/time as a floating-point number in UTC, in the format used by the python time module. Note that it is possible to create date /time values with DateTime that have no meaningful value to the time module, and in such cases a DateTimeError is raised. A DateTime object's value must generally be between Jan 1, 1970 (or your local machine epoch) and Jan 2038 to produce a valid time.time() style value. >>> dt = DateTime('Mar 9, 1997 13:45:00 US/Eastern') >>> dt.timeTime() 857933100.0 >>> DateTime('2040/01/01 UTC').timeTime() 2208988800.0 >>> DateTime('1900/01/01 UTC').timeTime() -2208988800.0 * ``toZone(z)`` returns a DateTime with the value as the current object, represented in the indicated timezone: >>> dt.toZone('UTC') DateTime('1997/03/09 18:45:00 UTC') >>> dt.toZone('UTC') == dt True * ``isFuture()`` returns true if this object represents a date/time later than the time of the call: >>> dt.isFuture() False >>> DateTime('Jan 1 3000').isFuture() # not time-machine safe!

NOTE: __cmp__ support is provided for backward compatibility only, and mixing DateTimes with ExtensionClasses could cause __cmp__ to break. You should use the methods lessThan, greaterThan, lessThanEqualTo, greaterThanEqualTo, equalTo and notEqualTo to avoid potential problems later! >>> cmp(dt, dt) 0 >>> cmp(dt, dt.toZone('UTC')) 0 >>> cmp(dt, dt.timeTime()) 0 >>> cmp(dt, DateTime('2000/01/01')) -1 >>> cmp(dt, DateTime('1900/01/01')) 1 DateTime objects can be compared to other DateTime objects OR floating point numbers such as the ones which are returned by the python time module.

DateTime instances constructed under version 3 can be read and unpickled by this version. The pickled data is converted to the current versions format (old-style class / no slots). Once converted it will be stored again in the old format. This should allow for a transparent upgrade/downgrade path between DateTime 2 and 3. 2.12.6 (2010-10-17) ------------------- - Changed ``testDayOfWeek`` test to be independent of OS locale. 2.12.5 (2010-07-29) ------------------- - Launchpad #143269: Corrected the documentation for year value behavior when constructing a DateTime object with three numeric arguments. - Launchpad #142521: Removed confusing special case in DateTime.__str__ where DateTime instances for midnight (e.g. '2010-07-27 00:00:00 US/Eastern') values would render only their date and nothing else. 2.12.4 (2010-07-12) ------------------- - Fixed mapping of EDT (was -> 'GMT-0400', now 'GMT-4'). 2.12.3 (2010-07-09) ------------------- - Added EDT timezone support.

[vangheem] 2.12.2 (2010-05-05) ------------------- - Launchpad #572715: Relaxed pin on pytz, after applying a patch from Marius Gedminus which fixes the apparent API breakage. 2.12.1 (2010-04-30) ------------------- - Removed an undeclared testing dependency on zope.testing.doctest in favor of the standard libraries doctest module. - Added a maximum version requirement on pytz <= 2010b. Later versions produce test failures related to timezone changes. 2.12.0 (2009-03-04) ------------------- - Launchpad #290254: Forward-ported fix for '_micros'-less pickles from the Zope 2.11 branch version. 2.11.2 (2009-02-02) ------------------- - Include *all* pytz zone names, not just "common" ones. - Fix one fragile doctest, band-aid another. - Fix for launchpad #267545: DateTime(DateTime()) should preserve the correct hour. 2.11.1 (2008-08-05) ------------------- - DateTime conversion of datetime objects with non-pytz tzinfo. Timezones() returns a copy of the timezone list (allows tests to run). - Merged the slinkp-datetime-200007 branch: fix the DateTime(anotherDateTime) constructor to preserve timezones. 2.11.0b1 (2008-01-06) --------------------- - Split off from the Zope2 main source code tree.

arnauarnauThe DateTime package ==================== Encapsulation of date/time values. Function Timezones() -------------------- Returns the list of recognized timezone names: >>> from DateTime import Timezones >>> zones = set(Timezones()) Almost all of the standard pytz timezones are included, with the exception of some commonly-used but ambiguous abbreviations, where historical Zope usage conflicts with the name used by pytz: >>> import pytz >>> [x for x in pytz.all_timezones if x not in zones] ['CET', 'EET', 'EST', 'MET', 'MST', 'WET'] Class DateTime -------------- DateTime objects represent instants in time and provide interfaces for controlling its representation without affecting the absolute value of the object. DateTime objects may be created from a wide variety of string or numeric data, or may be computed from other DateTime objects. DateTimes support the ability to convert their representations to many major timezones, as well as the ablility to create a DateTime object in the context of a given timezone. DateTime objects provide partial numerical behavior: * Two date-time objects can be subtracted to obtain a time, in days between the two. * A date-time object and a positive or negative number may be added to obtain a new date-time object that is the given number of days later than the input date-time object. * A positive or negative number and a date-time object may be added to obtain a new date-time object that is the given number of days later than the input date-time object. * A positive or negative number may be subtracted from a date-time object to obtain a new date-time object that is the given number of days earlier than the input date-time object. DateTime objects may be converted to integer, long, or float numbers of days since January 1, 1901, using the standard int, long, and float functions (Compatibility Note: int, long and float return the number of days since 1901 in GMT rather than local machine timezone). DateTime objects also provide access to their value in a float format usable with the python time module, provided that the value of the object falls in the range of the epoch-based time module. A DateTime object should be considered immutable; all conversion and numeric operations return a new DateTime object rather than modify the current object. A DateTime object always maintains its value as an absolute UTC time, and is represented in the context of some timezone based on the arguments used to create the object. A DateTime object's methods return values based on the timezone context. Note that in all cases the local machine timezone is used for representation if no timezone is specified. Constructor for DateTime ------------------------ DateTime() returns a new date-time object. DateTimes may be created with from zero to seven arguments: * If the function is called with no arguments, then the current date/ time is returned, represented in the timezone of the local machine. * If the function is invoked with a single string argument which is a recognized timezone name, an object representing the current time is returned, represented in the specified timezone. * If the function is invoked with a single string argument representing a valid date/time, an object representing that date/ time will be returned. As a general rule, any date-time representation that is recognized and unambigous to a resident of North America is acceptable. (The reason for this qualification is that in North America, a date like: 2/1/1994 is interpreted as February 1, 1994, while in some parts of the world, it is interpreted as January 2, 1994.) A date/ time string consists of two components, a date component and an optional time component, separated by one or more spaces. If the time component is omited, 12:00am is assumed. Any recognized timezone name specified as the final element of the date/time string will be used for computing the date/time value. (If you create a DateTime with the string "Mar 9, 1997 1:45pm US/Pacific", the value will essentially be the same as if you had captured time.time() at the specified date and time on a machine in that timezone). o Returns current date/time, represented in US/Eastern: >>> from DateTime import DateTime >>> e = DateTime('US/Eastern') >>> e.timezone() 'US/Eastern' o Returns specified time, represented in local machine zone: >>> x = DateTime('1997/3/9 1:45pm') >>> x.parts() # doctest: +ELLIPSIS (1997, 3, 9, 13, 45, 0.0, ...) o Specified time in local machine zone, verbose format: >>> y = DateTime('Mar 9, 1997 13:45:00') >>> y.parts() # doctest: +ELLIPSIS (1997, 3, 9, 13, 45, 0.0, ...) >>> y == x True The date component consists of year, month, and day values. The year value must be a one-, two-, or four-digit integer. If a one- or two-digit year is used, the year is assumed to be in the twentieth century. The month may an integer, from 1 to 12, a month name, or a month abreviation, where a period may optionally follow the abreviation. The day must be an integer from 1 to the number of days in the month. The year, month, and day values may be separated by periods, hyphens, forward, shashes, or spaces. Extra spaces are permitted around the delimiters. Year, month, and day values may be given in any order as long as it is possible to distinguish the components. If all three components are numbers that are less than 13, then a a month-day-year ordering is assumed. The time component consists of hour, minute, and second values separated by colons. The hour value must be an integer between 0 and 23 inclusively. The minute value must be an integer between 0 and 59 inclusively. The second value may be an integer value between 0 and 59.999 inclusively. The second value or both the minute and second values may be ommitted. The time may be followed by am or pm in upper or lower case, in which case a 12-hour clock is assumed. * If the DateTime function is invoked with a single Numeric argument, the number is assumed to be either a floating point value such as that returned by time.time() , or a number of days after January 1, 1901 00:00:00 UTC. A DateTime object is returned that represents either the gmt value of the time.time() float represented in the local machine's timezone, or that number of days after January 1, 1901. Note that the number of days after 1901 need to be expressed from the viewpoint of the local machine's timezone. A negative argument will yield a date-time value before 1901. * If the function is invoked with two numeric arguments, then the first is taken to be an integer year and the second argument is taken to be an offset in days from the beginning of the year, in the context of the local machine timezone. The date-time value returned is the given offset number of days from the beginning of the given year, represented in the timezone of the local machine. The offset may be positive or negative. Two-digit years are assumed to be in the twentieth century. * If the function is invoked with two arguments, the first a float representing a number of seconds past the epoch in gmt (such as those returned by time.time()) and the second a string naming a recognized timezone, a DateTime with a value of that gmt time will be returned, represented in the given timezone. >>> import time >>> t = time.time() Time t represented as US/Eastern: >>> now_east = DateTime(t, 'US/Eastern') Time t represented as US/Pacific: >>> now_west = DateTime(t, 'US/Pacific') Only their representations are different: >>> now_east == now_west True * If the function is invoked with three or more numeric arguments, then the first is taken to be an integer year, the second is taken to be an integer month, and the third is taken to be an integer day. If the combination of values is not valid, then a DateTimeError is raised. One- or two-digit years up to 69 are assumed to be in the 21st century, whereas values 70-99 are assumed to be 20th century. The fourth, fifth, and sixth arguments are floating point, positive or negative offsets in units of hours, minutes, and days, and default to zero if not given. An optional string may be given as the final argument to indicate timezone (the effect of this is as if you had taken the value of time.time() at that time on a machine in the specified timezone). If a string argument passed to the DateTime constructor cannot be parsed, it will raise DateTime.SyntaxError. Invalid date, time, or timezone components will raise a DateTime.DateTimeError. The module function Timezones() will return a list of the timezones recognized by the DateTime module. Recognition of timezone names is case-insensitive. Instance Methods for DateTime (IDateTime interface) --------------------------------------------------- Conversion and comparison methods ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ``timeTime()`` returns the date/time as a floating-point number in UTC, in the format used by the python time module. Note that it is possible to create date /time values with DateTime that have no meaningful value to the time module, and in such cases a DateTimeError is raised. A DateTime object's value must generally be between Jan 1, 1970 (or your local machine epoch) and Jan 2038 to produce a valid time.time() style value. >>> dt = DateTime('Mar 9, 1997 13:45:00 US/Eastern') >>> dt.timeTime() 857933100.0 >>> DateTime('2040/01/01 UTC').timeTime() 2208988800.0 >>> DateTime('1900/01/01 UTC').timeTime() -2208988800.0 * ``toZone(z)`` returns a DateTime with the value as the current object, represented in the indicated timezone: >>> dt.toZone('UTC') DateTime('1997/03/09 18:45:00 UTC') >>> dt.toZone('UTC') == dt True * ``isFuture()`` returns true if this object represents a date/time later than the time of the call: >>> dt.isFuture() False >>> DateTime('Jan 1 3000').isFuture() # not time-machine safe!

NOTE: __cmp__ support is provided for backward compatibility only, and mixing DateTimes with ExtensionClasses could cause __cmp__ to break. You should use the methods lessThan, greaterThan, lessThanEqualTo, greaterThanEqualTo, equalTo and notEqualTo to avoid potential problems later! >>> cmp(dt, dt) 0 >>> cmp(dt, dt.toZone('UTC')) 0 >>> cmp(dt, dt.timeTime()) 0 >>> cmp(dt, DateTime('2000/01/01')) -1 >>> cmp(dt, DateTime('1900/01/01')) 1 DateTime objects can be compared to other DateTime objects OR floating point numbers such as the ones which are returned by the python time module.

The advantage of using pytz is that it has a more complete and up to date time zone and daylight savings time database. Usage ----- You don't have to do anything special to make it work. >>> from DateTime import DateTime, Timezones >>> d = DateTime('March 11, 2007 US/Eastern') Daylight Savings ---------------- In 2007 daylight savings time in the US was changed. The Energy Policy Act of 2005 mandates that DST will start on the second Sunday in March and end on the first Sunday in November. In 2007, the start and stop dates are March 11 and November 4, respectively. These dates are different from previous DST start and stop dates. In 2006, the dates were the first Sunday in April (April 2, 2006) and the last Sunday in October (October 29, 2006). Let's make sure that DateTime can deal with this, since the primary motivation to use pytz for time zone information is the fact that it is kept up to date with daylight savings changes. >>> DateTime('March 11, 2007 US/Eastern').tzoffset() -18000 >>> DateTime('March 12, 2007 US/Eastern').tzoffset() -14400 >>> DateTime('November 4, 2007 US/Eastern').tzoffset() -14400 >>> DateTime('November 5, 2007 US/Eastern').tzoffset() -18000 Let's compare this to 2006. >>> DateTime('April 2, 2006 US/Eastern').tzoffset() -18000 >>> DateTime('April 3, 2006 US/Eastern').tzoffset() -14400 >>> DateTime('October 29, 2006 US/Eastern').tzoffset() -14400 >>> DateTime('October 30, 2006 US/Eastern').tzoffset() -18000 Time Zones --------- DateTime can use pytz's large database of time zones. Here are some examples: >>> d = DateTime('Pacific/Kwajalein') >>> d = DateTime('America/Shiprock') >>> d = DateTime('Africa/Ouagadougou') Of course pytz doesn't know about everything. >>> d = DateTime('July 21, 1969 Moon/Eastern') Traceback (most recent call last): ... SyntaxError: July 21, 1969 Moon/Eastern You can still use zone names that DateTime defines that aren't part of the pytz database. >>> d = DateTime('eet') >>> d = DateTime('iceland') These time zones use DateTimes database. So it's preferable to use the official time zone name. One trickiness is that DateTime supports some zone name abbreviations. Some of these map to pytz names, so these abbreviations will give you time zone date from pytz. Notable among abbreviations that work this way are 'est', 'cst', 'mst', and 'pst'. Let's verify that 'est' picks up the 2007 daylight savings time changes. >>> DateTime('March 11, 2007 est').tzoffset() -18000 >>> DateTime('March 12, 2007 est').tzoffset() -14400 >>> DateTime('November 4, 2007 est').tzoffset() -14400 >>> DateTime('November 5, 2007 est').tzoffset() -18000 You can get a list of time zones supported by calling the Timezones() function. >>> Timezones() #doctest: +ELLIPSIS ['Africa/Abidjan', 'Africa/Accra', 'Africa/Addis_Ababa', ...] Note that you can mess with this list without hurting things. >>> t = Timezones() >>> t.remove('US/Eastern') >>> d = DateTime('US/Eastern') Python Versions --------------- Both pytz and DateTime should work under Python 2.3 as well as Python 2.4. Internal Components ------------------- The following are tests of internal components. Cache ~~~~~ The DateTime class uses a new time zone cache. >>> DateTime._tzinfo #doctest: +ELLIPSIS The cache maps time zone names to time zone instances. >>> cache = DateTime._tzinfo >>> tz = cache['GMT+730'] >>> tz = cache['US/Mountain'] The cache also must provide a few attributes for use by the DateTime class. The _zlst attribute is a list of supported time zone names. >>> cache._zlst #doctest: +ELLIPSIS ['Africa/Abidjan'... 'Africa/Accra'... 'IDLE'... 'NZST'... 'NZT'...] The _zidx attribute is a list of lower-case and possibly abbreviated time zone names that can be mapped to offical zone names. >>> cache._zidx #doctest: +ELLIPSIS [... 'australia/yancowinna'... 'gmt+0500'... 'europe/isle_of_man'...] Note that there are more items in _zidx than in _zlst since there are multiple names for some time zones. >>> len(cache._zidx) > len(cache._zlst) True Each entry in _zlst should also be present in _zidx in lower case form. >>> for name in cache._zlst: ... if not name.lower() in cache._zidx: ... print "Error %s not in _zidx" % name.lower() The _zmap attribute maps the names in _zidx to official names in _zlst. >>> cache._zmap['africa/abidjan'] 'Africa/Abidjan' >>> cache._zmap['gmt+1'] 'GMT+1' >>> cache._zmap['gmt+0100'] 'GMT+1' >>> cache._zmap['utc'] 'UTC' Let's make sure that _zmap and _zidx agree. >>> idx = list(cache._zidx) >>> idx.sort() >>> keys = cache._zmap.keys() >>> keys.sort() >>> idx == keys True Timezone objects ~~~~~~~~~~~~~~~~ The timezone instances have only one public method info(). It returns a tuple of (offset, is_dst, name). The method takes a timestamp, which is used to determine dst information. >>> t1 = DateTime('November 4, 00:00 2007 US/Mountain').timeTime() >>> t2 = DateTime('November 4, 02:00 2007 US/Mountain').timeTime() >>> tz.info(t1) (-21600, 1, 'MDT') >>> tz.info(t2) (-25200, 0, 'MST') If you don't pass any arguments to info it provides daylight savings time information as of today. >>> tz.info() in ((-21600, 1, 'MDT'), (-25200, 0, 'MST')) True zope2.13-2.13.21/source/DateTime/src/DateTime/__init__.py0000644000175000017500000000124112214017435021524 0ustar arnauarnau############################################################################## # # Copyright (c) 2002 Zope Foundation and Contributors. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

DateTime objects may be created from a wide variety of string or numeric data, or may be computed from other DateTime objects. DateTimes support the ability to convert their representations to many major timezones, as well as the ablility to create a DateTime object in the context of a given timezone.

DateTime objects may be converted to integer, long, or float numbers of days since January 1, 1901, using the standard int, long, and float functions (Compatibility Note: int, long and float return the number of days since 1901 in GMT rather than local machine timezone). DateTime objects also provide access to their value in a float format usable with the python time module, provided that the value of the object falls in the range of the epoch-based time module, and as a datetime.datetime object.

A DateTime object always maintains its value as an absolute UTC time, and is represented in the context of some timezone based on the arguments used to create the object. A DateTime object's methods return values based on the timezone context. Note that in all cases the local machine timezone is used for representation if no timezone is specified. DateTimes may be created with from zero to seven arguments. - If the function is called with no arguments or with None, then the current date/time is returned, represented in the timezone of the local machine. - If the function is invoked with a single string argument which is a recognized timezone name, an object representing the current time is returned, represented in the specified timezone. - If the function is invoked with a single string argument representing a valid date/time, an object representing that date/time will be returned. As a general rule, any date-time representation that is recognized and unambigous to a resident of North America is acceptable. The reason for this qualification is that in North America, a date like: 2/1/1994 is interpreted as February 1, 1994, while in some parts of the world, it is interpreted as January 2, 1994. A date/time string consists of two components, a date component and an optional time component, separated by one or more spaces. If the time component is omited, 12:00am is assumed. Any recognized timezone name specified as the final element of the date/time string will be used for computing the date/time value. If you create a DateTime with the string 'Mar 9, 1997 1:45pm US/Pacific', the value will essentially be the same as if you had captured time.time() at the specified date and time on a machine in that timezone: 
            e=DateTime('US/Eastern')
            # returns current date/time, represented in US/Eastern.

            x=DateTime('1997/3/9 1:45pm')
            # returns specified time, represented in local machine zone.

            y=DateTime('Mar 9, 1997 13:45:00')
            # y is equal to x
The date component consists of year, month, and day values. The year value must be a one-, two-, or four-digit integer. If a one- or two-digit year is used, the year is assumed to be in the twentieth century. The month may be an integer, from 1 to 12, a month name, or a month abreviation, where a period may optionally follow the abreviation. The day must be an integer from 1 to the number of days in the month. The year, month, and day values may be separated by periods, hyphens, forward, shashes, or spaces. Extra spaces are permitted around the delimiters. Year, month, and day values may be given in any order as long as it is possible to distinguish the components. If all three components are numbers that are less than 13, then a a month-day-year ordering is assumed. The time component consists of hour, minute, and second values separated by colons. The hour value must be an integer between 0 and 23 inclusively. The minute value must be an integer between 0 and 59 inclusively. The second value may be an integer value between 0 and 59.999 inclusively. The second value or both the minute and second values may be ommitted. The time may be followed by am or pm in upper or lower case, in which case a 12-hour clock is assumed. New in Zope 2.4: The DateTime constructor automatically detects and handles ISO8601 compliant dates (YYYY-MM-DDThh:ss:mmTZD). New in Zope 2.9.6: The existing ISO8601 parser was extended to support almost the whole ISO8601 specification. New formats includes: 
            y=DateTime('1993-045')
            # returns the 45th day from 1993, which is 14th February

            w=DateTime('1993-W06-7')
            # returns the 7th day from the 6th week from 1993, which
            # is also 14th February
See http://en.wikipedia.org/wiki/ISO_8601 for full specs. Note that the Zope DateTime parser assumes timezone naive ISO strings to be in UTC rather than local time as specified. - If the DateTime function is invoked with a single Numeric argument, the number is assumed to be a floating point value such as that returned by time.time(). A DateTime object is returned that represents the GMT value of the time.time() float represented in the local machine's timezone. - If the DateTime function is invoked with a single argument that is a DateTime instane, a copy of the passed object will be created. - New in 2.11: The DateTime function may now be invoked with a single argument that is a datetime.datetime instance. DateTimes may be converted back to datetime.datetime objects with asdatetime(). DateTime instances may be converted to a timezone naive datetime.datetime in UTC with utcdatetime(). - If the function is invoked with two numeric arguments, then the first is taken to be an integer year and the second argument is taken to be an offset in days from the beginning of the year, in the context of the local machine timezone. The date-time value returned is the given offset number of days from the beginning of the given year, represented in the timezone of the local machine. The offset may be positive or negative. Two-digit years are assumed to be in the twentieth century. - If the function is invoked with two arguments, the first a float representing a number of seconds past the epoch in gmt (such as those returned by time.time()) and the second a string naming a recognized timezone, a DateTime with a value of that gmt time will be returned, represented in the given timezone. 
            import time
            t=time.time()

            now_east=DateTime(t,'US/Eastern')
            # Time t represented as US/Eastern

            now_west=DateTime(t,'US/Pacific')
            # Time t represented as US/Pacific

            # now_east == now_west
            # only their representations are different
- If the function is invoked with three or more numeric arguments, then the first is taken to be an integer year, the second is taken to be an integer month, and the third is taken to be an integer day. If the combination of values is not valid, then a DateError is raised. Two-digit years are assumed to be in the twentieth century. The fourth, fifth, and sixth arguments specify a time in hours, minutes, and seconds; hours and minutes should be positive integers and seconds is a positive floating point value, all of these default to zero if not given. An optional string may be given as the final argument to indicate timezone (the effect of this is as if you had taken the value of time.time() at that time on a machine in the specified timezone). New in Zope 2.7: A new keyword parameter "datefmt" can be passed to the constructor. If set to "international", the constructor is forced to treat ambigious dates as "days before month before year". This useful if you need to parse non-US dates in a reliable way In any case that a floating point number of seconds is given or derived, it's rounded to the nearest millisecond. If a string argument passed to the DateTime constructor cannot be parsed, it will raise DateTime.SyntaxError. Invalid date components will raise a DateError, while invalid time or timezone components will raise a DateTimeError. The module function Timezones() will return a list of the (common) timezones recognized by the DateTime module. Recognition of timezone names is case-insensitive.

Unless you need to communicate with Zope 2 APIs, you're probably better off using Python's bult-in datetime module. Home-page: http://pypi.python.org/pypi/DateTime Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: The DateTime package ==================== Encapsulation of date/time values. Function Timezones() -------------------- Returns the list of recognized timezone names: >>> from DateTime import Timezones >>> zones = set(Timezones()) Almost all of the standard pytz timezones are included, with the exception of some commonly-used but ambiguous abbreviations, where historical Zope usage conflicts with the name used by pytz: >>> import pytz >>> [x for x in pytz.all_timezones if x not in zones] ['CET', 'EET', 'EST', 'MET', 'MST', 'WET'] Class DateTime -------------- DateTime objects represent instants in time and provide interfaces for controlling its representation without affecting the absolute value of the object. DateTime objects may be created from a wide variety of string or numeric data, or may be computed from other DateTime objects. DateTimes support the ability to convert their representations to many major timezones, as well as the ablility to create a DateTime object in the context of a given timezone. DateTime objects provide partial numerical behavior: * Two date-time objects can be subtracted to obtain a time, in days between the two. * A date-time object and a positive or negative number may be added to obtain a new date-time object that is the given number of days later than the input date-time object. * A positive or negative number and a date-time object may be added to obtain a new date-time object that is the given number of days later than the input date-time object. * A positive or negative number may be subtracted from a date-time object to obtain a new date-time object that is the given number of days earlier than the input date-time object. DateTime objects may be converted to integer, long, or float numbers of days since January 1, 1901, using the standard int, long, and float functions (Compatibility Note: int, long and float return the number of days since 1901 in GMT rather than local machine timezone). DateTime objects also provide access to their value in a float format usable with the python time module, provided that the value of the object falls in the range of the epoch-based time module. A DateTime object should be considered immutable; all conversion and numeric operations return a new DateTime object rather than modify the current object. A DateTime object always maintains its value as an absolute UTC time, and is represented in the context of some timezone based on the arguments used to create the object. A DateTime object's methods return values based on the timezone context. Note that in all cases the local machine timezone is used for representation if no timezone is specified. Constructor for DateTime ------------------------ DateTime() returns a new date-time object. DateTimes may be created with from zero to seven arguments: * If the function is called with no arguments, then the current date/ time is returned, represented in the timezone of the local machine. * If the function is invoked with a single string argument which is a recognized timezone name, an object representing the current time is returned, represented in the specified timezone. * If the function is invoked with a single string argument representing a valid date/time, an object representing that date/ time will be returned. As a general rule, any date-time representation that is recognized and unambigous to a resident of North America is acceptable. (The reason for this qualification is that in North America, a date like: 2/1/1994 is interpreted as February 1, 1994, while in some parts of the world, it is interpreted as January 2, 1994.) A date/ time string consists of two components, a date component and an optional time component, separated by one or more spaces. If the time component is omited, 12:00am is assumed. Any recognized timezone name specified as the final element of the date/time string will be used for computing the date/time value. (If you create a DateTime with the string "Mar 9, 1997 1:45pm US/Pacific", the value will essentially be the same as if you had captured time.time() at the specified date and time on a machine in that timezone). o Returns current date/time, represented in US/Eastern: >>> from DateTime import DateTime >>> e = DateTime('US/Eastern') >>> e.timezone() 'US/Eastern' o Returns specified time, represented in local machine zone: >>> x = DateTime('1997/3/9 1:45pm') >>> x.parts() # doctest: +ELLIPSIS (1997, 3, 9, 13, 45, 0.0, ...) o Specified time in local machine zone, verbose format: >>> y = DateTime('Mar 9, 1997 13:45:00') >>> y.parts() # doctest: +ELLIPSIS (1997, 3, 9, 13, 45, 0.0, ...) >>> y == x True The date component consists of year, month, and day values. The year value must be a one-, two-, or four-digit integer. If a one- or two-digit year is used, the year is assumed to be in the twentieth century. The month may an integer, from 1 to 12, a month name, or a month abreviation, where a period may optionally follow the abreviation. The day must be an integer from 1 to the number of days in the month. The year, month, and day values may be separated by periods, hyphens, forward, shashes, or spaces. Extra spaces are permitted around the delimiters. Year, month, and day values may be given in any order as long as it is possible to distinguish the components. If all three components are numbers that are less than 13, then a a month-day-year ordering is assumed. The time component consists of hour, minute, and second values separated by colons. The hour value must be an integer between 0 and 23 inclusively. The minute value must be an integer between 0 and 59 inclusively. The second value may be an integer value between 0 and 59.999 inclusively. The second value or both the minute and second values may be ommitted. The time may be followed by am or pm in upper or lower case, in which case a 12-hour clock is assumed. * If the DateTime function is invoked with a single Numeric argument, the number is assumed to be either a floating point value such as that returned by time.time() , or a number of days after January 1, 1901 00:00:00 UTC. A DateTime object is returned that represents either the gmt value of the time.time() float represented in the local machine's timezone, or that number of days after January 1, 1901. Note that the number of days after 1901 need to be expressed from the viewpoint of the local machine's timezone. A negative argument will yield a date-time value before 1901. * If the function is invoked with two numeric arguments, then the first is taken to be an integer year and the second argument is taken to be an offset in days from the beginning of the year, in the context of the local machine timezone. The date-time value returned is the given offset number of days from the beginning of the given year, represented in the timezone of the local machine. The offset may be positive or negative. Two-digit years are assumed to be in the twentieth century. * If the function is invoked with two arguments, the first a float representing a number of seconds past the epoch in gmt (such as those returned by time.time()) and the second a string naming a recognized timezone, a DateTime with a value of that gmt time will be returned, represented in the given timezone. >>> import time >>> t = time.time() Time t represented as US/Eastern: >>> now_east = DateTime(t, 'US/Eastern') Time t represented as US/Pacific: >>> now_west = DateTime(t, 'US/Pacific') Only their representations are different: >>> now_east == now_west True * If the function is invoked with three or more numeric arguments, then the first is taken to be an integer year, the second is taken to be an integer month, and the third is taken to be an integer day. If the combination of values is not valid, then a DateTimeError is raised. One- or two-digit years up to 69 are assumed to be in the 21st century, whereas values 70-99 are assumed to be 20th century. The fourth, fifth, and sixth arguments are floating point, positive or negative offsets in units of hours, minutes, and days, and default to zero if not given. An optional string may be given as the final argument to indicate timezone (the effect of this is as if you had taken the value of time.time() at that time on a machine in the specified timezone). If a string argument passed to the DateTime constructor cannot be parsed, it will raise DateTime.SyntaxError. Invalid date, time, or timezone components will raise a DateTime.DateTimeError. The module function Timezones() will return a list of the timezones recognized by the DateTime module. Recognition of timezone names is case-insensitive. Instance Methods for DateTime (IDateTime interface) --------------------------------------------------- Conversion and comparison methods ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ``timeTime()`` returns the date/time as a floating-point number in UTC, in the format used by the python time module. Note that it is possible to create date /time values with DateTime that have no meaningful value to the time module, and in such cases a DateTimeError is raised. A DateTime object's value must generally be between Jan 1, 1970 (or your local machine epoch) and Jan 2038 to produce a valid time.time() style value. >>> dt = DateTime('Mar 9, 1997 13:45:00 US/Eastern') >>> dt.timeTime() 857933100.0 >>> DateTime('2040/01/01 UTC').timeTime() 2208988800.0 >>> DateTime('1900/01/01 UTC').timeTime() -2208988800.0 * ``toZone(z)`` returns a DateTime with the value as the current object, represented in the indicated timezone: >>> dt.toZone('UTC') DateTime('1997/03/09 18:45:00 UTC') >>> dt.toZone('UTC') == dt True * ``isFuture()`` returns true if this object represents a date/time later than the time of the call: >>> dt.isFuture() False >>> DateTime('Jan 1 3000').isFuture() # not time-machine safe!

NOTE: __cmp__ support is provided for backward compatibility only, and mixing DateTimes with ExtensionClasses could cause __cmp__ to break. You should use the methods lessThan, greaterThan, lessThanEqualTo, greaterThanEqualTo, equalTo and notEqualTo to avoid potential problems later! >>> cmp(dt, dt) 0 >>> cmp(dt, dt.toZone('UTC')) 0 >>> cmp(dt, dt.timeTime()) 0 >>> cmp(dt, DateTime('2000/01/01')) -1 >>> cmp(dt, DateTime('1900/01/01')) 1 DateTime objects can be compared to other DateTime objects OR floating point numbers such as the ones which are returned by the python time module. On comparison for equality, True is returned if the object represents a date/time equal to the specified DateTime or time module style time: >>> dt == dt True >>> dt == dt.toZone('UTC') True >>> dt == dt.timeTime() True >>> dt == DateTime() False >>> dt.equalTo(dt) True >>> dt.equalTo(dt.toZone('UTC')) True >>> dt.equalTo(dt.timeTime()) True >>> dt.equalTo(DateTime()) False Same goes for inequalities: >>> dt != dt False >>> dt != dt.toZone('UTC') False >>> dt != dt.timeTime() False >>> dt != DateTime() True >>> dt.notEqualTo(dt) False >>> dt.notEqualTo(dt.toZone('UTC')) False >>> dt.notEqualTo(dt.timeTime()) False >>> dt.notEqualTo(DateTime()) True >>> dt > dt False >>> DateTime() > dt True >>> dt > DateTime().timeTime() False >>> DateTime().timeTime() > dt True >>> dt.greaterThan(dt) False >>> DateTime().greaterThan(dt) True >>> dt.greaterThan(DateTime().timeTime()) False >>> dt >= dt True >>> DateTime() >= dt True >>> dt >= DateTime().timeTime() False >>> DateTime().timeTime() >= dt True >>> dt.greaterThanEqualTo(dt) True >>> DateTime().greaterThanEqualTo(dt) True >>> dt.greaterThanEqualTo(DateTime().timeTime()) False >>> dt < dt False >>> DateTime() < dt False >>> dt < DateTime().timeTime() True >>> DateTime().timeTime() < dt False >>> dt.lessThan(dt) False >>> DateTime().lessThan(dt) False >>> dt.lessThan(DateTime().timeTime()) True >>> dt <= dt True >>> DateTime() <= dt False >>> dt <= DateTime().timeTime() True >>> DateTime().timeTime() <= dt False >>> dt.lessThanEqualTo(dt) True >>> DateTime().lessThanEqualTo(dt) False >>> dt.lessThanEqualTo(DateTime().timeTime()) True Numeric Services Provided by DateTime ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ A DateTime may be added to a number and a number may be added to a DateTime: >>> dt + 5 DateTime('1997/03/14 13:45:00 US/Eastern') >>> 5 + dt DateTime('1997/03/14 13:45:00 US/Eastern') Two DateTimes cannot be added: >>> dt + dt Traceback (most recent call last): ...

DateTime instances constructed under version 3 can be read and unpickled by this version. The pickled data is converted to the current versions format (old-style class / no slots). Once converted it will be stored again in the old format. This should allow for a transparent upgrade/downgrade path between DateTime 2 and 3. 2.12.6 (2010-10-17) ------------------- - Changed ``testDayOfWeek`` test to be independent of OS locale. 2.12.5 (2010-07-29) ------------------- - Launchpad #143269: Corrected the documentation for year value behavior when constructing a DateTime object with three numeric arguments. - Launchpad #142521: Removed confusing special case in DateTime.__str__ where DateTime instances for midnight (e.g. '2010-07-27 00:00:00 US/Eastern') values would render only their date and nothing else. 2.12.4 (2010-07-12) ------------------- - Fixed mapping of EDT (was -> 'GMT-0400', now 'GMT-4'). 2.12.3 (2010-07-09) ------------------- - Added EDT timezone support. Addresses bug #599856. [vangheem] 2.12.2 (2010-05-05) ------------------- - Launchpad #572715: Relaxed pin on pytz, after applying a patch from Marius Gedminus which fixes the apparent API breakage. 2.12.1 (2010-04-30) ------------------- - Removed an undeclared testing dependency on zope.testing.doctest in favor of the standard libraries doctest module. - Added a maximum version requirement on pytz <= 2010b. Later versions produce test failures related to timezone changes. 2.12.0 (2009-03-04) ------------------- - Launchpad #290254: Forward-ported fix for '_micros'-less pickles from the Zope 2.11 branch version. 2.11.2 (2009-02-02) ------------------- - Include *all* pytz zone names, not just "common" ones. - Fix one fragile doctest, band-aid another. - Fix for launchpad #267545: DateTime(DateTime()) should preserve the correct hour. 2.11.1 (2008-08-05) ------------------- - DateTime conversion of datetime objects with non-pytz tzinfo. Timezones() returns a copy of the timezone list (allows tests to run). - Merged the slinkp-datetime-200007 branch: fix the DateTime(anotherDateTime) constructor to preserve timezones. 2.11.0b1 (2008-01-06) --------------------- - Split off from the Zope2 main source code tree.

Annotation factories -------------------- There is more to document about annotations, but we'll just sketch out a scenario on how to use the annotation factory for now. This is one of the easiest ways to use annotations -- basically you can see them as persistent, writable adapters. First, let's make a persistent object we can create annotations for: >>> from zope import interface >>> class IFoo(interface.Interface): ... pass >>> from zope.annotation.interfaces import IAttributeAnnotatable >>> from persistent import Persistent >>> class Foo(Persistent): ... interface.implements(IFoo, IAttributeAnnotatable) We directly say that Foo implements IAttributeAnnotatable here. In practice this is often done in ZCML, using the `implements` subdirective of the `content` or `class` directive. Now let's create an annotation for this: >>> class IBar(interface.Interface): ... a = interface.Attribute('A') ... b = interface.Attribute('B') >>> from zope import component >>> class Bar(Persistent): ... interface.implements(IBar) ... component.adapts(IFoo) ... def __init__(self): ... self.a = 1 ... self.b = 2 Note that the annotation implementation does not expect any arguments to its `__init__`. Otherwise it's basically an adapter. Now, we'll register the annotation as an adapter. To do this we use the `factory` function provided by `zope.annotation`: >>> from zope.annotation import factory >>> component.provideAdapter(factory(Bar)) Note that we do not need to specify what the adapter provides or what it adapts - we already do this on the annotation class itself. Now let's make an instance of `Foo`, and make an annotation for it. >>> foo = Foo() >>> bar = IBar(foo) >>> bar.a 1 >>> bar.b 2 We'll change `a` and get the annotation again. Our change is still there: >>> bar.a = 3 >>> IBar(foo).a 3 Of course it's still different for another instance of `Foo`: >>> foo2 = Foo() >>> IBar(foo2).a 1 What if our annotation does not provide what it adapts with `component.adapts`? It will complain: >>> class IQux(interface.Interface): ... pass >>> class Qux(Persistent): ... interface.implements(IQux) >>> component.provideAdapter(factory(Qux)) # doctest: +ELLIPSIS Traceback (most recent call last): ... TypeError: Missing 'zope.component.adapts' on annotation It's possible to provide an annotation with an explicit key.

This has to be re-established every time we retrieve the object (Guard against former bug: proxy wasn't established when the annotation existed already.) >>> old_hoi = IHoi(foo3) >>> old_hoi.__parent__ >>> old_hoi.__name__ 'my.unique.key' >>> zope.location.interfaces.ILocation.providedBy(old_hoi) True LocationProxies --------------- Suppose your annotation proxy provides ILocation. >>> class IPolloi(interface.Interface): ... pass >>> class Polloi(Persistent): ... interface.implements(IPolloi, zope.location.interfaces.ILocation) ... component.adapts(IFoo) ... __name__ = __parent__ = 0 >>> component.provideAdapter(factory(Polloi, 'my.other.key')) Sometimes you're adapting an object wrapped in a LocationProxy. >>> foo4 = Foo() >>> import zope.location.location >>> wrapped_foo4 = zope.location.location.LocationProxy(foo4, None, 'foo4') >>> located_polloi = IPolloi(wrapped_foo4) At first glance it looks as if located_polloi is located under wrapped_foo4. >>> located_polloi.__parent__ is wrapped_foo4 True >>> located_polloi.__name__ 'my.other.key' but that's because we received a LocationProxy >>> print type(located_polloi).__name__ LocationProxy If we unwrap located_polloi and look at it directly, we'll see it stores a reference to the real Foo object >>> from zope.proxy import removeAllProxies >>> removeAllProxies(located_polloi).__parent__ is foo4 True >>> removeAllProxies(located_polloi).__name__ 'my.other.key' ======= CHANGES ======= 3.5.0 (2009-09-07) ------------------ - Add ZODB3 to install_requires, because it's a true requirement of this package, not just a testing requirement, as BTrees are in use. - Fix one test that was inactive because it's function was overriden by a mistake. 3.4.2 (2009-03-09) ------------------ - Clean up package description and documentation a bit. - Change mailing list address to zope-dev at zope.org, as zope3-dev at zope.org is now retired. - Remove old zpkg-related files. 3.4.1 (2008-08-26) ------------------ - Annotation factories take care not to store proxies in the database, so adapting an object wrapped in a ``LocationProxy`` works correctly. Fixes https://bugs.launchpad.net/zope3/+bug/261620 3.4.0 (2007-08-29) ------------------ - Annotation factories are no longer containing the factored object. Instead the objects are located using ``zope.location``. This removes a dependency to ``zope.app.container``.

Annotation factories -------------------- There is more to document about annotations, but we'll just sketch out a scenario on how to use the annotation factory for now. This is one of the easiest ways to use annotations -- basically you can see them as persistent, writable adapters. First, let's make a persistent object we can create annotations for: >>> from zope import interface >>> class IFoo(interface.Interface): ... pass >>> from zope.annotation.interfaces import IAttributeAnnotatable >>> from persistent import Persistent >>> class Foo(Persistent): ... interface.implements(IFoo, IAttributeAnnotatable) We directly say that Foo implements IAttributeAnnotatable here. In practice this is often done in ZCML, using the `implements` subdirective of the `content` or `class` directive. Now let's create an annotation for this: >>> class IBar(interface.Interface): ... a = interface.Attribute('A') ... b = interface.Attribute('B') >>> from zope import component >>> class Bar(Persistent): ... interface.implements(IBar) ... component.adapts(IFoo) ... def __init__(self): ... self.a = 1 ... self.b = 2 Note that the annotation implementation does not expect any arguments to its `__init__`. Otherwise it's basically an adapter. Now, we'll register the annotation as an adapter. To do this we use the `factory` function provided by `zope.annotation`: >>> from zope.annotation import factory >>> component.provideAdapter(factory(Bar)) Note that we do not need to specify what the adapter provides or what it adapts - we already do this on the annotation class itself. Now let's make an instance of `Foo`, and make an annotation for it. >>> foo = Foo() >>> bar = IBar(foo) >>> bar.a 1 >>> bar.b 2 We'll change `a` and get the annotation again. Our change is still there: >>> bar.a = 3 >>> IBar(foo).a 3 Of course it's still different for another instance of `Foo`: >>> foo2 = Foo() >>> IBar(foo2).a 1 What if our annotation does not provide what it adapts with `component.adapts`? It will complain: >>> class IQux(interface.Interface): ... pass >>> class Qux(Persistent): ... interface.implements(IQux) >>> component.provideAdapter(factory(Qux)) # doctest: +ELLIPSIS Traceback (most recent call last): ... TypeError: Missing 'zope.component.adapts' on annotation It's possible to provide an annotation with an explicit key.

Annotation factories -------------------- There is more to document about annotations, but we'll just sketch out a scenario on how to use the annotation factory for now. This is one of the easiest ways to use annotations -- basically you can see them as persistent, writable adapters. First, let's make a persistent object we can create annotations for: >>> from zope import interface >>> class IFoo(interface.Interface): ... pass >>> from zope.annotation.interfaces import IAttributeAnnotatable >>> from persistent import Persistent >>> class Foo(Persistent): ... interface.implements(IFoo, IAttributeAnnotatable) We directly say that Foo implements IAttributeAnnotatable here. In practice this is often done in ZCML, using the `implements` subdirective of the `content` or `class` directive. Now let's create an annotation for this: >>> class IBar(interface.Interface): ... a = interface.Attribute('A') ... b = interface.Attribute('B') >>> from zope import component >>> class Bar(Persistent): ... interface.implements(IBar) ... component.adapts(IFoo) ... def __init__(self): ... self.a = 1 ... self.b = 2 Note that the annotation implementation does not expect any arguments to its `__init__`. Otherwise it's basically an adapter. Now, we'll register the annotation as an adapter. To do this we use the `factory` function provided by `zope.annotation`: >>> from zope.annotation import factory >>> component.provideAdapter(factory(Bar)) Note that we do not need to specify what the adapter provides or what it adapts - we already do this on the annotation class itself. Now let's make an instance of `Foo`, and make an annotation for it. >>> foo = Foo() >>> bar = IBar(foo) >>> bar.a 1 >>> bar.b 2 We'll change `a` and get the annotation again. Our change is still there: >>> bar.a = 3 >>> IBar(foo).a 3 Of course it's still different for another instance of `Foo`: >>> foo2 = Foo() >>> IBar(foo2).a 1 What if our annotation does not provide what it adapts with `component.adapts`? It will complain: >>> class IQux(interface.Interface): ... pass >>> class Qux(Persistent): ... interface.implements(IQux) >>> component.provideAdapter(factory(Qux)) # doctest: +ELLIPSIS Traceback (most recent call last): ... TypeError: Missing 'zope.component.adapts' on annotation It's possible to provide an annotation with an explicit key. (If the key is not supplied, the key is deduced from the annotation's dotted name, provided it is a class.) >>> class IHoi(interface.Interface): ... pass >>> class Hoi(Persistent): ... interface.implements(IHoi) ... component.adapts(IFoo) >>> component.provideAdapter(factory(Hoi, 'my.unique.key')) >>> isinstance(IHoi(foo), Hoi) True Location -------- Annotation factories are put into the location hierarchy with their parent pointing to the annotated object and the name to the dotted name of the annotation's class (or the name the adapter was registered under): >>> foo3 = Foo() >>> new_hoi = IHoi(foo3) >>> new_hoi.__parent__ >>> new_hoi.__name__ 'my.unique.key' >>> import zope.location.interfaces >>> zope.location.interfaces.ILocation.providedBy(new_hoi) True Please notice, that our Hoi object does not implement ILocation, so a location proxy will be used. This has to be re-established every time we retrieve the object (Guard against former bug: proxy wasn't established when the annotation existed already.) >>> old_hoi = IHoi(foo3) >>> old_hoi.__parent__ >>> old_hoi.__name__ 'my.unique.key' >>> zope.location.interfaces.ILocation.providedBy(old_hoi) True LocationProxies --------------- Suppose your annotation proxy provides ILocation. >>> class IPolloi(interface.Interface): ... pass >>> class Polloi(Persistent): ... interface.implements(IPolloi, zope.location.interfaces.ILocation) ... component.adapts(IFoo) ... __name__ = __parent__ = 0 >>> component.provideAdapter(factory(Polloi, 'my.other.key')) Sometimes you're adapting an object wrapped in a LocationProxy. >>> foo4 = Foo() >>> import zope.location.location >>> wrapped_foo4 = zope.location.location.LocationProxy(foo4, None, 'foo4') >>> located_polloi = IPolloi(wrapped_foo4) At first glance it looks as if located_polloi is located under wrapped_foo4. >>> located_polloi.__parent__ is wrapped_foo4 True >>> located_polloi.__name__ 'my.other.key' but that's because we received a LocationProxy >>> print type(located_polloi).__name__ LocationProxy If we unwrap located_polloi and look at it directly, we'll see it stores a reference to the real Foo object >>> from zope.proxy import removeAllProxies >>> removeAllProxies(located_polloi).__parent__ is foo4 True >>> removeAllProxies(located_polloi).__name__ 'my.other.key' ======= CHANGES ======= 3.5.0 (2009-09-07) ------------------ - Add ZODB3 to install_requires, because it's a true requirement of this package, not just a testing requirement, as BTrees are in use. - Fix one test that was inactive because it's function was overriden by a mistake. 3.4.2 (2009-03-09) ------------------ - Clean up package description and documentation a bit. - Change mailing list address to zope-dev at zope.org, as zope3-dev at zope.org is now retired. - Remove old zpkg-related files. 3.4.1 (2008-08-26) ------------------ - Annotation factories take care not to store proxies in the database, so adapting an object wrapped in a ``LocationProxy`` works correctly. Fixes https://bugs.launchpad.net/zope3/+bug/261620 3.4.0 (2007-08-29) ------------------ - Annotation factories are no longer containing the factored object. Instead the objects are located using ``zope.location``. This removes a dependency to ``zope.app.container``.

There is not much we can test except that ``IView`` is importable and an interface: >>> from zope.interface import Interface >>> from zope.browser.interfaces import IView >>> Interface.providedBy(IView) True IBrowserView ------------- Browser views are views specialized for requests from a browser (e.g., as distinct from WebDAV, FTP, XML-RPC, etc.). There is not much we can test except that ``IBrowserView`` is importable and an interface derived from ``IView``: >>> from zope.interface import Interface >>> from zope.browser.interfaces import IBrowserView >>> Interface.providedBy(IBrowserView) True >>> IBrowserView.extends(IView) True IAdding ------- Adding views manage how newly-created items get added to containers. There is not much we can test except that ``IAdding`` is importable and an interface derived from ``IBrowserView``: >>> from zope.interface import Interface >>> from zope.browser.interfaces import IAdding >>> Interface.providedBy(IBrowserView) True >>> IAdding.extends(IBrowserView) True ITerms ------ The ``ITerms`` interface is used as a base for ``ISource`` widget implementations. This interfaces get used by ``zope.app.form`` and was initially defined in ``zope.app.form.browser.interfaces``, which made it impossible to use for other packages like ``z3c.form`` wihtout depending on ``zope.app.form``. Moving such base components / interfaces to ``zope.browser`` makes it possible to share them without undesirable dependencies. There is not much we can test except that ITerms is importable and an interface: >>> from zope.interface import Interface >>> from zope.browser.interfaces import ITerms >>> Interface.providedBy(ITerms) True ISystemErrorView ---------------- Views providing this interface can classify their contexts as system errors. These errors can be handled in a special way (e. g. more detailed logging). There is not much we can test except that ISystemErrorView is importable and an interface: >>> from zope.interface import Interface >>> from zope.browser.interfaces import ISystemErrorView >>> Interface.providedBy(ISystemErrorView) True Changelog ========= 1.3 (2010-04-30) ---------------- - Removed test extra and zope.testing dependency. 1.2 (2009-05-18) ---------------- - Moved ``ISystemErrorView`` interface here from ``zope.app.exception`` to break undesirable dependencies. - Fixed home page and author's e-mail address. - Added doctests to long_description. 1.1 (2009-05-13) ---------------- - Moved ``IAdding`` interface here from ``zope.app.container.interfaces`` to break undesirable dependencies. 1.0 (2009-05-13) ---------------- - Moved ``IView`` and ``IBrowserView`` interfaces here from ``zope.publisher.interfaces`` to break undesirable dependencies. 0.5.0 (2008-12-11) ------------------ - Moved ``ITerms`` interface here from ``zope.app.form.browser.interfaces`` to break undesirable dependencies.

Applications can take advantage of object database features with few, if any, changes to application logic. ZODB includes features such as a plugable storage interface, rich transaction support, and undo. .. contents:: ==== ZODB ==== Introduction ============ The ZODB package provides a set of tools for using the Zope Object Database (ZODB). The components you get with the ZODB release are as follows: - Core ZODB, including the persistence machinery - Standard storages such as FileStorage - The persistent BTrees modules - ZEO, for scalability needs - documentation (needs a lot more work) Our primary development platforms are Linux, Mac OS X, and Windows XP. The test suite should pass without error on all of these platforms, although it can take a long time on Windows -- longer if you use ZoneAlarm. Many particularly slow tests are skipped unless you pass --all as an argument to test.py. Compatibility ============= ZODB 3.10 requires Python 2.5 or later. Note -- When using ZEO and upgrading from Python 2.4, you need to upgrade clients and servers at the same time, or upgrade clients first and then servers. Clients running Python 2.5 or 2.6 will work with servers running Python 2.4. Clients running Python 2.4 won't work properly with servers running Python 2.5 or later due to changes in the way Python implements exceptions. ZODB ZEO clients from ZODB 3.2 on can talk to ZODB 3.10 servers. ZODB ZEO 3.10 Clients can talk to ZODB 3.8, 3.9, and 3.10 ZEO servers. Note -- ZEO 3.10 servers don't support undo for older clients. Prerequisites ============= You must have Python installed. If you're using a system Python install, make sure development support is installed too. You also need the transaction, zc.lockfile, ZConfig, zdaemon, zope.event, zope.interface, zope.proxy and zope.testing packages. If you don't have them and you can connect to the Python Package Index, then these will be installed for you if you don't have them. Installation ============ ZODB is released as a distutils package. The easiest ways to build and install it are to use `easy_install `_, or `zc.buildout `_. To install by hand, first install the dependencies, ZConfig, zdaemon, zope.interface, zope.proxy and zope.testing. These can be found in the `Python Package Index `_. To run the tests, use the test setup command:: python setup.py test It will download dependencies if needed. If this happens, ou may get an import error when the test command gets to looking for tests. Try running the test command a second time and you should see the tests run. :: python setup.py test To install, use the install command:: python setup.py install Testing for Developers ====================== The ZODB checkouts are `buildouts `_. When working from a ZODB checkout, first run the bootstrap.py script to initialize the buildout: % python bootstrap.py and then use the buildout script to build ZODB and gather the dependencies: % bin/buildout This creates a test script: % bin/test -v This command will run all the tests, printing a single dot for each test. When it finishes, it will print a test summary. The exact number of tests can vary depending on platform and available third-party libraries.:: Ran 1182 tests in 241.269s OK The test script has many more options. Use the ``-h`` or ``--help`` options to see a file list of options. The default test suite omits several tests that depend on third-party software or that take a long time to run. To run all the available tests use the ``--all`` option. Running all the tests takes much longer.:: Ran 1561 tests in 1461.557s OK Maintenance scripts ------------------- Several scripts are provided with the ZODB and can help for analyzing, debugging, checking for consistency, summarizing content, reporting space used by objects, doing backups, artificial load testing, etc. Look at the ZODB/script directory for more informations. History ======= The historical version numbering schemes for ZODB and ZEO are complicated. Starting with ZODB 3.4, the ZODB and ZEO version numbers are the same. In the ZODB 3.1 through 3.3 lines, the ZEO version number was "one smaller" than the ZODB version number; e.g., ZODB 3.2.7 included ZEO 2.2.7. ZODB and ZEO were distinct releases prior to ZODB 3.1, and had independent version numbers. Historically, ZODB was distributed as a part of the Zope application server. Jim Fulton's paper at the Python conference in 2000 described a version of ZODB he called ZODB 3, based on an earlier persistent object system called BoboPOS. The earliest versions of ZODB 3 were released with Zope 2.0. Andrew Kuchling extracted ZODB from Zope 2.4.1 and packaged it for use by standalone Python programs. He called this version "StandaloneZODB". Andrew's guide to using ZODB is included in the Doc directory. This version of ZODB was hosted at http://sf.net/projects/zodb. It supported Python 1.5.2, and might still be of interest to users of this very old Python version. Zope Corporation released a version of ZODB called "StandaloneZODB 1.0" in Feb. 2002. This release was based on Andrew's packaging, but built from the same CVS repository as Zope. It is roughly equivalent to the ZODB in Zope 2.5. Why not call the current release StandaloneZODB? The name StandaloneZODB is a bit of a mouthful. The standalone part of the name suggests that the Zope version is the real version and that this is an afterthought, which isn't the case. So we're calling this release "ZODB". We also worked on a ZODB4 package for a while and made a couple of alpha releases. We've now abandoned that effort, because we didn't have the resources to pursue ot while also maintaining ZODB(3).

Local Variables: mode: indented-text indent-tabs-mode: nil sentence-end-double-space: t fill-column: 70 End: ================ Change History ================ 3.10.5 (2011-11-19) =================== Bugs Fixed ---------- - Conflict resolution failed when state included cross-database persistent references with classes that couldn't be imported. 3.10.4 (2011-11-17) =================== Bugs Fixed ---------- - Conflict resolution failed when state included persistent references with classes that couldn't be imported. 3.10.3 (2011-04-12) =================== Bugs Fixed ---------- - "activity monitor not updated for subconnections when connection returned to pool" https://bugs.launchpad.net/zodb/+bug/737198 - "Blob temp file get's removed before it should", https://bugs.launchpad.net/zodb/+bug/595378 A way this to happen is that a transaction is aborted after the commit process has started. I don't know how this would happen in the wild. In 3.10.3, the ZEO tpc_abort call to the server is changed to be synchronous, which should address this case. Maybe there's another case. Performance enhancements ------------------------ - Improved ZEO client cache implementation to make it less likely to evict objects that are being used. - Small (possibly negligable) reduction in CPU in ZEO storage servers to service object loads and in networking code. 3.10.2 (2011-02-12) =================== Bugs Fixed ---------- - 3.10 introduced an optimization to try to address BTree conflict errors arrising for basing BTree keys on object ids. The optimization caused object ids allocated in aborted transactions to be reused. Unfortunately, this optimzation led to some rather severe failures in some applications. The symptom is a conflict error in which one of the serials mentioned is zero. This optimization has been removed. See (for example): https://bugs.launchpad.net/zodb/+bug/665452 - ZEO server transaction timeouts weren't logged as critical. https://bugs.launchpad.net/zodb/+bug/670986 3.10.1 (2010-10-27) =================== Bugs Fixed ---------- - When a transaction rolled back a savepoint after adding objects and subsequently added more objects and committed, an error could be raised "ValueError: A different object already has the same oid" causing the transaction to fail. Worse, this could leave a database in a state where subsequent transactions in the same process would fail. https://bugs.launchpad.net/zodb/+bug/665452 - Unix domain sockets didn't work for ZEO (since the addition of IPv6 support). https://bugs.launchpad.net/zodb/+bug/663259 - Removed a missfeature that can cause performance problems when using an external garbage collector with ZEO. When objects were deleted from a storage, invalidations were sent to clients. This makes no sense. It's wildly unlikely that the other connections/clients have copies of the garbage. In normal storage garbage collection, we don't send invalidations. There's no reason to send them when an external garbage collector is used. - ZEO client cache simulation misshandled invalidations causing incorrect statistics and errors. 3.10.0 (2010-10-08) =================== New Features ------------ - There are a number of performance enhancements for ZEO storage servers. - FileStorage indexes use a new format. They are saved and loaded much faster and take less space. Old indexes can still be read, but new indexes won't be readable by older versions of ZODB. - The API for undoing multiple transactions has changed. To undo multiple transactions in a single transaction, pass a list of transaction identifiers to a database's undoMultiple method. Calling a database's undo method multiple times in the same transaction now raises an exception. - The ZEO protocol for undo has changed. The only user-visible consequence of this is that when ZODB 3.10 ZEO servers won't support undo for older clients. - The storage API (IStorage) has been tightened. Now, storages should raise a StorageTransactionError when invalid transactions are passed to tpc_begin, tpc_vote, or tpc_finish. - ZEO clients (``ClientStorage`` instances) now work in forked processes, including those created via ``multiprocessing.Process`` instances. - Broken objects now provide the IBroken interface. - As a convenience, you can now pass an integer port as an address to the ZEO ClientStorage constructor. - As a convenience, there's a new ``client`` function in the ZEO package for constructing a ClientStorage instance. It takes the same arguments as the ClientStorage constructor. - DemoStorages now accept constructor athuments, close_base_on_close and close_changes_on_close, to control whether underlying storages are closed when the DemoStorage is closed. https://bugs.launchpad.net/zodb/+bug/118512 - Removed the dependency on zope.proxy. - Removed support for the _p_independent mini framework, which was made moot by the introduction of multi-version concurrency control several years ago. - Added support for the transaction retry convenience (transaction-manager attempts method) introduced in the ``transaction`` 1.1.0 release. - Enhanced the database opening conveniences: - You can now pass storage keyword arguments to ZODB.DB and ZODB.connection. - You can now pass None (rather than a storage or file name) to get a database with a mapping storage. - Databases now warn when committing very large records (> 16MB). This is to try to warn people of likely design mistakes. There is a new option (large_record_size/large-record-size) to control the record size at which the warning is issued. - Added support for wrapper storages that transform pickle data. Applications for this include compression and encryption. An example wrapper storage implementation, ZODB.tests.hexstorage, was included for testing. It is important that storage implementations not assume that storages contain pickles. Renamed IStorageDB to IStorageWrapper and expanded it to provide methods for transforming and untransforming data records. Storages implementations should use these methods to get pickle data from stored records. - Deprecated ZODB.interfaces.StorageStopIteration. Storage iterator implementations should just raise StopIteration, which means they can now be implemented as generators. - The filestorage packer configuration option noe accepts values of the form ``modname:expression``, allowing the use of packer factories with options. - Added a new API that allows applications to make sure that current data are read. For example, with:: self._p_jar.readCurrent(ob) A conflict error will be raised if the version of ob read by the transaction isn't current when the transaction is committed. Normally, ZODB only assures that objects read are consistent, but not necessarily up to date. Checking whether an object is up to date is important when information read from one object is used to update another. BTrees are an important case of reading one object to update another. Internal nodes are read to decide which leave notes are updated when a BTree is updated. BTrees now use this new API to make sure that internal nodes are up to date on updates. - When transactions are aborted, new object ids allocated during the transaction are saved and used in subsequent transactions. This can help in situations where object ids are used as BTree keys and the sequential allocation of object ids leads to conflict errors. - ZEO servers now support a server_status method for for getting information on the number of clients, lock requests and general statistics. - ZEO clients now support a client_label constructor argument and client-label configuration-file option to specify a label for a client in server logs. This makes it easier to identify specific clients corresponding to server log entries, especially when there are multiple clients originating from the same machine. - Improved ZEO server commit lock logging. Now, locking activity is logged at the debug level until the number of waiting lock requests gets above 3. Log at the critical level when the number of waiting lock requests gets above 9. - The file-storage backup script, repozo, will now create a backup index file if an output file name is given via the --output/-o option. - Added a '--kill-old-on-full' argument to the repozo backup options: if passed, remove any older full or incremental backup files from the repository after doing a full backup. (https://bugs.launchpad.net/zope2/+bug/143158) - The mkzeoinst script has been moved to a separate project: http://pypi.python.org/pypi/zope.mkzeoinstance and is no-longer included with ZODB. - Removed untested unsupported dbmstorage fossile. - ZEO servers no longer log their pids in every log message. It's just not interesting. :) Bugs fixed ---------- - When a pool timeout was specified for a database and old connections were removed due to timing out, an error occured due to a bug in the connection cleanup logic. - When multi-database connections were no longer used and cleaned up, their subconnections weren't cleaned up properly. - ZEO didn't work with IPv6 addrsses. Added IPv6 support contributed by Martin v. |Lowis|. - A file storage bug could cause ZEO clients to have incorrect information about current object revisions after reconnecting to a database server. - Updated the 'repozo --kill-old-on-full' option to remove any '.index' files corresponding to backups being removed. - ZEO extension methods failed when a client reconnected to a storage. (https://bugs.launchpad.net/zodb/+bug/143344) - Clarified the return Value for lastTransaction in the case when there aren't any transactions. Now a string of 8 nulls (aka "z64") is specified. - Setting _p_changed on a blob wo actually writing anything caused an error. (https://bugs.launchpad.net/zodb/+bug/440234) - The verbose mode of the fstest was broken. (https://bugs.launchpad.net/zodb/+bug/475996) - Object ids created in a savepoint that is rolled back wren't being reused. (https://bugs.launchpad.net/zodb/+bug/588389) - Database connections didn't invalidate cache entries when conflict errors were raised in response to checkCurrentSerialInTransaction errors. Normally, this shouldn't be a problem, since there should be pending invalidations for these oids which will cause the object to be invalidated. There have been issues with ZEO persistent cache management that have caused out of date data to remain in the cache. (It's possible that the last of these were addressed in the 3.10.0b5.) Invalidating read data when there is a conflict error provides some extra insurance. - The interface, ZODB.interfaces.IStorage was incorrect. The store method should never return a sequence of oid and serial pairs. - When a demo storage push method was used to create a new demo storage and the new storage was closed, the original was (incorrectly) closed. - There were numerous bugs in the ZEO cache tracing and analysis code. Cache simulation, while not perfect, seems to be much more accurate now than it was before. The ZEO cache trace statistics and simulation scripts have been given more descriptive names and moved to the ZEO scripts package. - BTree sets and tree sets didn't correctly check values passed to update or to constructors, causing Python to exit under certain circumstances. - Fixed bug in copying a BTrees.Length instance. (https://bugs.launchpad.net/zodb/+bug/516653) - Fixed a serious bug that caused cache failures when run with Python optimization turned on. https://bugs.launchpad.net/zodb/+bug/544305 - When using using a ClientStorage in a Storage server, there was a threading bug that caused clients to get disconnected. - On Mac OS X, clients that connected and disconnected quickly could cause a ZEO server to stop accepting connections, due to a failure to catch errors in the initial part of the connection process. The failure to properly handle exceptions while accepting connections is potentially problematic on other platforms. Fixes: https://bugs.launchpad.net/zodb/+bug/135108 - Object state management wasn't done correctly when classes implemented custom _p_deavtivate methods.

(https://bugs.launchpad.net/zodb/+bug/641481) Python 2.7 wasn't officially supported, but we were releasing binaries for it, so ... - Logrotation/repoening via a SIGUSR2 signal wasn't implemented. (https://bugs.launchpad.net/zodb/+bug/143600) - When using multi-databases, cache-management operations on a connection, cacheMinimize and cacheGC, weren't applied to subconnections. 3.9.6 (2010-09-21) ================== Bugs Fixed ---------- - Updating blobs in save points could cause spurious "invalidations out of order" errors. https://bugs.launchpad.net/zodb/+bug/509801 (Thanks to Christian Zagrodnick for chasing this down.) - If a ZEO client process was restarted while invalidating a ZEO cache entry, the cache could be left in a stage when there is data marked current that should be invalidated, leading to persistent conflict errors. - Corrupted or invalid cache files prevented ZEO clients from starting. Now, bad cache files are moved aside. - Invalidations of object records in ZEO caches, where the invalidation transaction ids matched the cached transaction ids should have been ignored. - Shutting down a process while committing a transaction or processing invalidations from the server could cause ZEO persistent client caches to have invalid data. This, in turn caused stale data to remain in the cache until it was updated. - Conflict errors didn't invalidate ZEO cache entries. - When objects were added in savepoints and either the savepoint was rolled back (https://bugs.launchpad.net/zodb/+bug/143560) or the transaction was aborted (https://mail.zope.org/pipermail/zodb-dev/2010-June/013488.html) The objects' _p_oid and _p_jar variables weren't cleared, leading to surprizing errors. - Objects added in transactions that were later aborted could have _p_changed still set (https://bugs.launchpad.net/zodb/+bug/615758). - ZEO extension methods failed when a client reconnected to a storage. (https://bugs.launchpad.net/zodb/+bug/143344) - On Mac OS X, clients that connected and disconnected quickly could cause a ZEO server to stop accepting connections, due to a failure to catch errors in the initial part of the connection process. The failure to properly handle exceptions while accepting connections is potentially problematic on other platforms. Fixes: https://bugs.launchpad.net/zodb/+bug/135108 - Passing keys or values outside the range of 32-bit ints on 64-bit platforms led to undetected overflow errors. Now these cases cause Type errors to be raised. https://bugs.launchpad.net/zodb/+bug/143237 - BTree sets and tree sets didn't correctly check values passed to update or to constructors, causing Python to exit under certain circumstances. - The verbose mode of the fstest was broken. (https://bugs.launchpad.net/zodb/+bug/475996) 3.9.5 (2010-04-23) ================== Bugs Fixed ---------- - Fixed bug in cPickleCache's byte size estimation logic. (https://bugs.launchpad.net/zodb/+bug/533015) - Fixed a serious bug that caused cache failures when run with Python optimization turned on. https://bugs.launchpad.net/zodb/+bug/544305 - Fixed a bug that caused savepoint rollback to not properly set object state when objects implemented _p_invalidate methods that reloaded ther state (unghostifiable objects). https://bugs.launchpad.net/zodb/+bug/428039 - cross-database wekrefs weren't handled correctly. https://bugs.launchpad.net/zodb/+bug/435547 - The mkzeoinst script was fixed to tell people to install and use the mkzeoinstance script. :) 3.9.4 (2009-12-14) ================== Bugs Fixed ---------- - A ZEO threading bug could cause transactions to read inconsistent data. (This sometimes caused an AssertionError in Connection._setstate_noncurrent.) - DemoStorage.loadBefore sometimes returned invalid data which would trigger AssertionErrors in ZODB.Connection. - History support was broken when using stprages that work with ZODB 3.8 and 3.9. - zope.testing was an unnecessary non-testing dependency. - Internal ZEO errors were logged at the INFO level, rather than at the error level. - The FileStorage backup and restore script, repozo, gave a deprecation warning under Python 2.6. - C Header files weren't installed correctly. - The undo implementation was incorrect in ways that could cause subtle missbehaviors. 3.9.3 (2009-10-23) ================== Bugs Fixed ---------- - 2 BTree bugs, introduced by a bug fix in 3.9.0c2, sometimes caused deletion of keys to be improperly handled, resulting in data being available via iteraation but not item access. 3.9.2 (2009-10-13) ================== Bugs Fixed ---------- - ZEO manages a separate thread for client network IO. It created this thread on import, which caused problems for applications that implemented daemon behavior by forking. Now, the client thread isn't created until needed. - File-storage pack clean-up tasks that can take a long time unnecessarily blocked other activity. - In certain rare situations, ZEO client connections would hang during the initial connection setup. 3.9.1 (2009-10-01) ================== Bugs Fixed ---------- - Conflict errors committing blobs caused ZEO servers to stop committing transactions. 3.9.0 (2009-09-08) ================== New Features (in more or less reverse chronological order) ---------------------------------------------------------- - The Database class now has an ``xrefs`` keyword argument and a corresponding allow-implicit-cross-references configuration option. which default to true. When set to false, cross-database references are disallowed. - Added support for RelStorage. - As a convenience, the connection root method for returning the root object can now *also* be used as an object with attributes mapped to the root-object keys. - Databases have a new method, ``transaction``, that can be used with the Python (2.5 and later) ``with`` statement:: db = ZODB.DB(...) with db.transaction() as conn: # ... do stuff with conn This uses a private transaction manager for the connection. If control exits the block without an error, the transaction is committed, otherwise, it is aborted. - Convenience functions ZODB.connection and ZEO.connection provide a convenient way to open a connection to a database. They open a database and return a connection to it. When the connection is closed, the database is closed as well. - The ZODB.config databaseFrom... methods now support multi-databases. If multiple zodb sections are used to define multiple databases, the databases are connected in a multi-database arrangement and the first of the defined databases is returned. - The zeopack script has gotten a number of improvements: - Simplified command-line interface. (The old interface is still supported, except that support for ZEO version 1 servers has been dropped.) - Multiple storages can be packed in sequence. - This simplifies pack scheduling on servers serving multiple databases. - All storages are packed to the same time. - You can now specify a time of day to pack to. - The script will now time out if it can't connect to s storage in 60 seconds. - The connection now estimates the object size based on its pickle size and informs the cache about size changes. The database got additional configurations options (`cache-size-bytes` and `historical-cache-size-bytes`) to limit the cache size based on the estimated total size of cached objects. The default values are 0 which has the interpretation "do not limit based on the total estimated size". There are corresponding methods to read and set the new configuration parameters. - Connections now have a public ``opened`` attribute that is true when the connection is open, and false otherwise. When true, it is the seconds since the epoch (time.time()) when the connection was opened. This is a renaming of the previous ``_opened`` private variable. - FileStorage now supports blobs directly. - You can now control whether FileStorages keep .old files when packing. - POSKeyErrors are no longer logged by ZEO servers, because they are really client errors. - A new storage interface, IExternalGC, to support external garbage collection, http://wiki.zope.org/ZODB/ExternalGC, has been defined and implemented for FileStorage and ClientStorage. - As a small convenience (mainly for tests), you can now specify initial data as a string argument to the Blob constructor. - ZEO Servers now provide an option, invalidation-age, that allows quick verification of ZEO clients have been disconnected for less than a given time even if the number of transactions the client hasn't seen exceeds the invalidation queue size. This is only recommended if the storage being served supports efficient iteration from a point near the end of the transaction history. - The FileStorage iterator now handles large files better. When iterating from a starting transaction near the end of the file, the iterator will scan backward from the end of the file to find the starting point. This enhancement makes it practical to take advantage of the new storage server invalidation-age option. - Previously, database connections were managed as a stack. This tended to cause the same connection(s) to be used over and over. For example, the most used connection would typically be the only connection used. In some rare situations, extra connections could be opened and end up on the top of the stack, causing extreme memory wastage. Now, when connections are placed on the stack, they sink below existing connections that have more active objects. - There is a new pool-timeout database configuration option to specify that connections unused after the given time interval should be garbage collection. This will provide a means of dealing with extra connections that are created in rare circumstances and that would consume an unreasonable amount of memory. - The Blob open method now supports a new mode, 'c', to open committed data for reading as an ordinary file, rather than as a blob file. The ordinary file may be used outside the current transaction and even after the blob's database connection has been closed. - ClientStorage now provides blob cache management. When using non-shared blob directories, you can set a target cache size and the cache will periodically be reduced try to keep it below the target size. The client blob directory layout has changed. If you have existing non-shared blob directories, you will have to remove them. - ZODB 3.9 ZEO clients can connect to ZODB 3.8 servers. ZODB ZEO clients from ZODB 3.2 on can connect to ZODB 3.9 servers. - When a ZEO cache is stale and would need verification, a ZEO.interfaces.StaleCache event is published (to zope.event). Applications may handle this event and take action such as exiting the application without verifying the cache or starting cold. - There's a new convenience function, ZEO.DB, for creating databases using ZEO Client Storages. Just call ZEO.DB with the same arguments you would otherwise pass to ZEO.ClientStorage.ClientStorage:: import ZEO db = ZEO.DB(('some_host', 8200)) - Object saves are a little faster - When configuring storages in a storage server, the storage name now defaults to "1". In the overwhelmingly common case that a single storage, the name can now be omitted. - FileStorage now provides optional garbage collection. A 'gc' keyword option can be passed to the pack method. A false value prevents garbage collection. - The FileStorage constructor now provides a boolean pack_gc option, which defaults to True, to control whether garbage collection is performed when packing by default. This can be overridden with the gc option to the pack method. The ZConfig configuration for FileStorage now includes a pack-gc option, corresponding to the pack_gc constructor argument. - The FileStorage constructor now has a packer keyword argument that allows an alternative packer to be supplied. The ZConfig configuration for FileStorage now includes a packer option, corresponding to the packer constructor argument. - MappingStorage now supports multi-version concurrency control and iteration and provides a better storage implementation example. - DemoStorage has a number of new features: - The ability to use a separate storage, such as a file storage to store changes - Blob support - Multi-version concurrency control and iteration - Explicit support for demo-storage stacking via push and pop methods. - Wen calling ZODB.DB to create a database, you can now pass a file name, rather than a storage to use a file storage. - Added support for copying and recovery of blob storages: - Added a helper function, ZODB.blob.is_blob_record for testing whether a data record is for a blob. This can be used when iterating over a storage to detect blob records so that blob data can be copied. In the future, we may want to build this into a blob-aware iteration interface, so that records get blob file attributes automatically. - Added the IBlobStorageRestoreable interfaces for blob storages that support recovery via a restoreBlob method. - Updated ZODB.blob.BlobStorage to implement IBlobStorageRestoreable and to have a copyTransactionsFrom method that also copies blob data. - New `ClientStorage` configuration option `drop_cache_rather_verify`. If this option is true then the ZEO client cache is dropped instead of the long (unoptimized) verification. For large caches, setting this option can avoid effective down times in the order of hours when the connection to the ZEO server was interrupted for a longer time. - Cleaned-up the storage iteration API and provided an iterator implementation for ZEO. - Versions are no-longer supported. - Document conflict resolution (see ZODB/ConflictResolution.txt). - Support multi-database references in conflict resolution. - Make it possible to examine oid and (in some situations) database name of persistent object references during conflict resolution. - Moved the 'transaction' module out of ZODB. ZODB depends upon this module, but it must be installed separately. - ZODB installation now requires setuptools. - Added `offset` information to output of `fstail` script. Added test harness for this script. - Added support for read-only, historical connections based on datetimes or serials (TIDs). See src/ZODB/historical_connections.txt. - Removed the ThreadedAsync module. - Now depend on zc.lockfile Bugs Fixed ---------- - CVE-2009-2701: Fixed a vulnerability in ZEO storage servers when blobs are available. Someone with write access to a ZEO server configured to support blobs could read any file on the system readable by the server process and remove any file removable by the server process. - BTrees (and TreeSets) kept references to internal keys. https://bugs.launchpad.net/zope3/+bug/294788 - BTree Sets and TreeSets don't support the standard set add method. (Now either add or the original insert method can be used to add an object to a BTree-based set.) - The runzeo script didn't work without a configuration file. (https://bugs.launchpad.net/zodb/+bug/410571) - Officially deprecated PersistentDict (https://bugs.launchpad.net/zodb/+bug/400775) - Calling __setstate__ on a persistent object could under certain uncommon cause the process to crash. (https://bugs.launchpad.net/zodb/+bug/262158) - When committing transactions involving blobs to ClientStorages with non-shared blob directories, a failure could occur in tpc_finish if there was insufficient disk space to copy the blob file or if the file wasn't available. https://bugs.launchpad.net/zodb/+bug/224169 - Savepoint blob data wasn't properly isolated. If multiple simultaneous savepoints in separate transactions modified the same blob, data from one savepoint would overwrite data for another. - Savepoint blob data wasn't cleaned up after a transaction abort. https://bugs.launchpad.net/zodb/+bug/323067 - Opening a blob with modes 'r+' or 'a' would fail when the blob had no committed changes. - PersistentList's sort method did not allow passing of keyword parameters. Changed its sort parameter list to match that of its (Python 2.4+) UserList base class. - Certain ZEO server errors could cause a client to get into a state where it couldn't commit transactions. https://bugs.launchpad.net/zodb/+bug/374737 - Fixed vulnerabilities in the ZEO network protocol that allow: - CVE-2009-0668 Arbitrary Python code execution in ZODB ZEO storage servers - CVE-2009-0669 Authentication bypass in ZODB ZEO storage servers The vulnerabilities only apply if you are using ZEO to share a database among multiple applications or application instances and if untrusted clients are able to connect to your ZEO servers. - Fixed the setup test command. It previously depended on private functions in zope.testing.testrunner that don't exist any more. - ZEO client threads were unnamed, making it hard to debug thread management. - ZEO protocol 2 support was broken. This caused very old clients to be unable to use new servers. - zeopack was less flexible than it was before. -h should default to local host. - The "lawn" layout was being selected by default if the root of the blob directory happened to contain a hidden file or directory such as ".svn". Now hidden files and directories are ignored when choosing the default layout. - BlobStorage was not compatible with MVCC storages because the wrappers were being removed by each database connection. Fixed. - Saving indexes for large file storages failed (with the error: RuntimeError: maximum recursion depth exceeded). This can cause a FileStorage to fail to start because it gets an error trying to save its index. - Sizes of new objects weren't added to the object cache size estimation, causing the object-cache size limiting feature to let the cache grow too large when many objects were added. - Deleted records weren't removed when packing file storages. - Fixed analyze.py and added test. - fixed Python 2.6 compatibility issue with ZEO/zeoserverlog.py - using hashlib.sha1 if available in order to avoid DeprecationWarning under Python 2.6 - made runzeo -h work - The monitor server didn't correctly report the actual number of clients. - Packing could return spurious errors due to errors notifying disconnected clients of new database size statistics. - Undo sometimes failed for FileStorages configured to support blobs. - Starting ClientStorages sometimes failed with non-new but empty cache files. - The history method on ZEO clients failed. - Fix for bug #251037: Make packing of blob storages non-blocking. - Fix for bug #220856: Completed implementation of ZEO authentication. - Fix for bug #184057: Make initialisation of small ZEO client file cache sizes not fail. - Fix for bug #184054: MappingStorage used to raise a KeyError during `load` instead of a POSKeyError. - Fixed bug in Connection.TmpStore: load() would not defer to the backend storage for loading blobs. - Fix for bug #181712: Make ClientStorage update `lastTransaction` directly after connecting to a server, even when no cache verification is necessary. - Fixed bug in blob filesystem helper: the `isSecure` check was inverted. - Fixed bug in transaction buffer: a tuple was unpacked incorrectly in `clear`. - Bugfix the situation in which comparing persistent objects (for instance, as members in BTree set or keys of BTree) might cause data inconsistency during conflict resolution. - Fixed bug 153316: persistent and BTrees were using `int` for memory sizes which caused errors on x86_64 Intel Xeon machines (using 64-bit Linux). - Fixed small bug that the Connection.isReadOnly method didn't work after a savepoint. - Bug #98275: Made ZEO cache more tolerant when invalidating current versions of objects. - Fixed a serious bug that could cause client I/O to stop (hang). This was accompanied by a critical log message along the lines of: "RuntimeError: dictionary changed size during iteration". - Fixed bug #127182: Blobs were subclassable which was not desired. - Fixed bug #126007: tpc_abort had untested code path that was broken. - Fixed bug #129921: getSize() function in BlobStorage could not deal with garbage files - Fixed bug in which MVCC would not work for blobs. - Fixed bug in ClientCache that occurred with objects larger than the total cache size. - When an error occured attempting to lock a file and logging of said error was enabled. - FileStorages previously saved indexes after a certain number of writes. This was done during the last phase of two-phase commit, which made this critical phase more subject to errors than it should have been. Also, for large databases, saves were done so infrequently as to be useless. The feature was removed to reduce the chance for errors during the last phase of two-phase commit. - File storages previously kept an internal object id to transaction id mapping as an optimization. This mapping caused excessive memory usage and failures during the last phase of two-phase commit. This optimization has been removed. - Refactored handling of invalidations on ZEO clients to fix a possible ordering problem for invalidation messages. - On many systems, it was impossible to create more than 32K blobs. Added a new blob-directory layout to work around this limitation. - Fixed bug that could lead to memory errors due to the use of a Python dictionary for a mapping that can grow large. - Fixed bug #251037: Made packing of blob storages non-blocking. - Fixed a bug that could cause InvalidObjectReference errors for objects that were explicitly added to a database if the object was modified after a savepoint that added the object. - Fixed several bugs that caused ZEO cache corruption when connecting to servers. These bugs affected both persistent and non-persistent caches. - Improved the the ZEO client shutdown support to try to avoid spurious errors on exit, especially for scripts, such as zeopack. - Packing failed for databases containing cross-database references. - Cross-database references to databases with empty names weren't constructed properly. - The zeo client cache used an excessive amount of memory, causing applications with large caches to exhaust available memory. - Fixed a number of bugs in the handling of persistent ZEO caches: - Cache records are written in several steps. If a process exits after writing begins and before it is finishes, the cache will be corrupt on restart. The way records are written was changed to make cache record updates atomic. - There was no lock file to prevent opening a cache multiple times at once, which would lead to corruption. Persistent caches now use lock files, in the same way that file storages do. - A bug in the cache-opening logic led to cache failure in the unlikely event that a cache has no free blocks. - When using ZEO Client Storages, Errors occured when trying to store objects too big to fit in the ZEO cache file. - Fixed bug in blob filesystem helper: the `isSecure` check was inverted. - Fixed bug in transaction buffer: a tuple was unpacked incorrectly in `clear`. - Fixed bug in Connection.TmpStore: load() would not defer to the back-end storage for loading blobs. - Fixed bug #190884: Wrong reference to `POSKeyError` caused NameError. - Completed implementation of ZEO authentication. This fixes issue 220856. What's new in ZODB 3.8.0 ======================== General ------- - (unreleased) Fixed setup.py use of setuptools vs distutils, so .c and .h files are included in the bdist_egg. - The ZODB Storage APIs have been documented and cleaned up. - ZODB versions are now officially deprecated and support for them will be removed in ZODB 3.9. (They have been widely recognized as deprecated for quite a while.) - Changed the automatic garbage collection when opening a connection to only apply the garbage collections on those connections in the pool that are closed. (This fixed issue 113923.) ZEO --- - (3.8a1) ZEO's strategoes for avoiding client cache verification were improved in the case that servers are restarted. Before, if transactions were committed after the restart, clients that were up to date or nearly up to date at the time of the restart and then connected had to verify their caches. Now, it is far more likely that a client that reconnects soon after a server restart won't have to verify its cache. - (3.8a1) Fixed a serious bug that could cause clients that disconnect from and reconnect to a server to get bad invalidation data if the server serves multiple storages with active writes. - (3.8a1) It is now theoretically possible to use a ClientStorage in a storage server. This might make it possible to offload read load from a storage server at the cost of increasing write latency. This should increase write throughput by offloading reads from the final storage server. This feature is somewhat experimental. It has tests, but hasn't been used in production. Transactions ------------ - (3.8a1) Add a doom() and isDoomed() interface to the transaction module. First step towards the resolution of http://www.zope.org/Collectors/Zope3-dev/655 A doomed transaction behaves exactly the same way as an active transaction but raises an error on any attempt to commit it, thus forcing an abort. Doom is useful in places where abort is unsafe and an exception cannot be raised. This occurs when the programmer wants the code following the doom to run but not commit. It is unsafe to abort in these circumstances as a following get() may implicitly open a new transaction. Any attempt to commit a doomed transaction will raise a DoomedTransaction exception. - (3.8a1) Clean up the ZODB imports in transaction. Clean up weird import dance with ZODB. This is unnecessary since the transaction module stopped being imported in ZODB/__init__.py in rev 39622. - (3.8a1) Support for subtransactions has been removed in favor of save points. Blobs ----- - (3.8b1) Updated the Blob implementation in a number of ways. Some of these are backward incompatible with 3.8a1: o The Blob class now lives in ZODB.blob o The blob openDetached method has been replaced by the committed method. - (3.8a1) Added new blob feature. See the ZODB/Blobs directory for documentation. ZODB now handles (reasonably) large binary objects efficiently. Useful to use from a few kilobytes to at least multiple hundred megabytes. BTrees ------ - (3.8a1) Added support for 64-bit integer BTrees as separate types. (For now, we're retaining compile-time support for making the regular integer BTrees 64-bit.) - (3.8a1) Normalize names in modules so that BTrees, Buckets, Sets, and TreeSets can all be accessed with those names in the modules (e.g., BTrees.IOBTree.BTree). This is in addition to the older names (e.g., BTrees.IOBTree.IOBTree). This allows easier drop-in replacement, which can especially be simplify code for packages that want to support both 32-bit and 64-bit BTrees. - (3.8a1) Describe the interfaces for each module and actually declare the interfaces for each. - (3.8a1) Fix module references so klass.__module__ points to the Python wrapper module, not the C extension. - (3.8a1) introduce module families, to group all 32-bit and all 64-bit modules. What's new in ZODB3 3.7.0 ========================== Release date: 2007-04-20 Packaging --------- - (3.7.0b3) ZODB is now packaged without it's dependencies ZODB no longer includes copies of dependencies such as ZConfig, zope.interface and so on. It now treats these as dependencies. If ZODB is installed with easy_install or zc.buildout, the dependencies will be installed automatically. - (3.7.0b3) ZODB is now a buildout ZODB checkouts are now built and tested using zc.buildout. - (3.7b4) Added logic to avoid spurious errors from the logging system on exit. - (3.7b2) Removed the "sync" mode for ClientStorage. Previously, a ClientStorage could be in either "sync" mode or "async" mode. Now there is just "async" mode. There is now a dedicicated asyncore main loop dedicated to ZEO clients. Applications no-longer need to run an asyncore main loop to cause client storages to run in async mode. Even if an application runs an asyncore main loop, it is independent of the loop used by client storages. This addresses a test failure on Mac OS X, http://www.zope.org/Collectors/Zope3-dev/650, that I believe was due to a bug in sync mode. Some asyncore-based code was being called from multiple threads that didn't expect to be. Converting to always-async mode revealed some bugs that weren't caught before because the tests ran in sync mode. These problems could explain some problems we've seen at times with clients taking a long time to reconnect after a disconnect. Added a partial heart beat to try to detect lost connections that aren't otherwise caught, http://mail.zope.org/pipermail/zodb-dev/2005-June/008951.html, by perioidically writing to all connections during periods of inactivity. Connection management --------------------- - (3.7a1) When more than ``pool_size`` connections have been closed, ``DB`` forgets the excess (over ``pool_size``) connections closed first. Python's cyclic garbage collection can take "a long time" to reclaim them (and may in fact never reclaim them if application code keeps strong references to them), but such forgotten connections can never be opened again, so their caches are now cleared at the time ``DB`` forgets them. Most applications won't notice a difference, but applications that open many connections, and/or store many large objects in connection caches, and/or store limited resources (such as RDB connections) in connection caches may benefit. BTrees ------ - Support for 64-bit integer keys and values has been provided as a compile-time option for the "I" BTrees (e.g. IIBTree). Documentation ------------- - (3.7a1) Thanks to Stephan Richter for converting many of the doctest files to ReST format. These are now chapters in the Zope 3 apidoc too. IPersistent ----------- - (3.7a1) The documentation for ``_p_oid`` now specifies the concrete type of oids (in short, an oid is either None or a non-empty string). Testing ------- - (3.7b2) Fixed test-runner output truncation. A bug was fixed in the test runner that caused result summaries to be omitted when running on Windows. Tools ----- - (3.7a1) The changeover from zLOG to the logging module means that some tools need to perform minimal logging configuration themselves. Changed the zeoup script to do so and thus enable it to emit error messages. BTrees ------ - (3.7a1) Suppressed warnings about signedness of characters when compiling under GCC 4.0.x. See http://www.zope.org/Collectors/Zope/2027. Connection ---------- - (3.7a1) An optimization for loading non-current data (MVCC) was inadvertently disabled in ``_setstate()``; this has been repaired. persistent ---------- - (3.7a1) Suppressed warnings about signedness of characters when compiling under GCC 4.0.x. See http://www.zope.org/Collectors/Zope/2027. - (3.7a1) PersistentMapping was inadvertently pickling volatile attributes (http://www.zope.org/Collectors/Zope/2052). After Commit hooks ------------------ - (3.7a1) Transaction objects have a new method, ``addAfterCommitHook(hook, *args, **kws)``. Hook functions registered with a transaction are called after the transaction commits or aborts. For example, one might want to launch non transactional or asynchrnonous code after a successful, or aborted, commit. See ``test_afterCommitHook()`` in ``transaction/tests/test_transaction.py`` for a tutorial doctest, and the ``ITransaction`` interface for details. What's new in ZODB3 3.6.2? ========================== Release date: 15-July-2006 DemoStorage ----------- - (3.6.2) DemoStorage was unable to wrap base storages who did not have an '_oid' attribute: most notably, ZEO.ClientStorage (http://www.zope.org/Collectors/Zope/2016). Following is combined news from internal releases (to support ongoing Zope2 / Zope3 development). These are the dates of the internal releases: - 3.6.1 27-Mar-2006 - 3.6.0 05-Jan-2006 - 3.6b6 01-Jan-2006 - 3.6b5 18-Dec-2005 - 3.6b4 04-Dec-2005 - 3.6b3 06-Nov-2005 - 3.6b2 25-Oct-2005 - 3.6b1 24-Oct-2005 - 3.6a4 07-Oct-2005 - 3.6a3 07-Sep-2005 - 3.6a2 06-Sep-2005 - 3.6a1 04-Sep-2005 Removal of Features Deprecated in ZODB 3.4 ------------------------------------------ (3.6b2) ZODB 3.6 no longer contains features officially deprecated in the ZODB 3.4 release. These include: - ``get_transaction()``. Use ``transaction.get()`` instead. ``transaction.commit()`` is a shortcut spelling of ``transaction.get().commit()``, and ``transaction.abort()`` of ``transaction.get().abort()``. Note that importing ZODB no longer installs ``get_transaction`` as a name in Python's ``__builtin__`` module either. - The ``begin()`` method of ``Transaction`` objects. Use the ``begin()`` method of a transaction manager instead. ``transaction.begin()`` is a shortcut spelling to call the default transaction manager's ``begin()`` method. - The ``dt`` argument to ``Connection.cacheMinimize()``. - The ``Connection.cacheFullSweep()`` method. Use ``cacheMinimize()`` instead. - The ``Connection.getTransaction()`` method. Pass a transaction manager to ``DB.open()`` instead. - The ``Connection.getLocalTransaction()`` method. Pass a transaction manager to ``DB.open()`` instead. - The ``cache_deactivate_after`` and ``version_cache_deactivate_after`` arguments to the ``DB`` constructor. - The ``temporary``, ``force``, and ``waitflag`` arguments to ``DB.open()``. ``DB.open()`` no longer blocks (there's no longer a fixed limit on the number of open connections). - The ``transaction`` and ``txn_mgr``arguments to ``DB.open()``. Use the ``transaction_manager`` argument instead. - The ``getCacheDeactivateAfter``, ``setCacheDeactivateAfter``, ``getVersionCacheDeactivateAfter`` and ``setVersionCacheDeactivateAfter`` methods of ``DB``. Persistent ---------- - (3.6.1) Suppressed warnings about signedness of characters when compiling under GCC 4.0.x. See http://www.zope.org/Collectors/Zope/2027. - (3.6a4) ZODB 3.6 introduces a change to the basic behavior of Persistent objects in a particular end case. Before ZODB 3.6, setting ``obj._p_changed`` to a true value when ``obj`` was a ghost was ignored: ``obj`` remained a ghost, and getting ``obj._p_changed`` continued to return ``None``. Starting with ZODB 3.6, ``obj`` is activated instead (unghostified), and its state is changed from the ghost state to the changed state. The new behavior is less surprising and more robust. - (3.6b5) The documentation for ``_p_oid`` now specifies the concrete type of oids (in short, an oid is either None or a non-empty string). Commit hooks ------------ - (3.6a1) The ``beforeCommitHook()`` method has been replaced by the new ``addBeforeCommitHook()`` method, with a more-robust signature. ``beforeCommitHook()`` is now deprecated, and will be removed in ZODB 3.8. Thanks to Julien Anguenot for contributing code and tests. Connection management --------------------- - (3.6b6) When more than ``pool_size`` connections have been closed, ``DB`` forgets the excess (over ``pool_size``) connections closed first. Python's cyclic garbage collection can take "a long time" to reclaim them (and may in fact never reclaim them if application code keeps strong references to them), but such forgotten connections can never be opened again, so their caches are now cleared at the time ``DB`` forgets them. Most applications won't notice a difference, but applications that open many connections, and/or store many large objects in connection caches, and/or store limited resources (such as RDB connections) in connection caches may benefit. ZEO --- - (3.6a4) Collector 1900. In some cases of pickle exceptions raised by low-level ZEO communication code, callers of ``marshal.encode()`` could attempt to catch an exception that didn't actually exist, leading to an erroneous ``AttributeError`` exception. Thanks to Tres Seaver for the diagnosis. BaseStorage ----------- - (3.6a4) Nothing done by ``tpc_abort()`` should raise an exception. However, if something does (an error case), ``BaseStorage.tpc_abort()`` left the commit lock in the acquired state, causing any later attempt to commit changes hang. Multidatabase ------------- - (3.6b1) The ``database_name`` for a database in a multidatabase collection can now be specified in a config file's ```` section, as the value of the optional new ``database_name`` key. The ``.databases`` attribute cannot be specified in a config file, but can be passed as the optional new ``databases`` argument to the ``open()`` method of a ZConfig factory for type ``ZODBDatabase``. For backward compatibility, Zope 2.9 continues to allow using the name in its ```` config section as the database name (note that ```` is defined by Zope, not by ZODB -- it's a Zope-specific extension of ZODB's ```` section). PersistentMapping ----------------- - (3.6.1) PersistentMapping was inadvertently pickling volatile attributes (http://www.zope.org/Collectors/Zope/2052). - (3.6b4) ``PersistentMapping`` makes changes by a ``pop()`` method call persistent now (http://www.zope.org/Collectors/Zope/2036). - (3.6a1) The ``PersistentMapping`` class has an ``__iter__()`` method now, so that objects of this type work well with Python's iteration protocol. For example, if ``x`` is a ``PersistentMapping`` (or Python dictionary, or BTree, or ``PersistentDict``, ...), then ``for key in x:`` iterates over the keys of ``x``, ``list(x)`` creates a list containing ``x``'s keys, ``iter(x)`` creates an iterator for ``x``'s keys, and so on. Tools ----- - (3.6b5) The changeover from zLOG to the logging module means that some tools need to perform minimal logging configuration themselves. Changed the zeoup script to do so and thus enable it to emit error messages. BTrees ------ - (3.6.1) Suppressed warnings about signedness of characters when compiling under GCC 4.0.x. See http://www.zope.org/Collectors/Zope/2027. - (3.6a1) BTrees and Buckets now implement the ``setdefault()`` and ``pop()`` methods. These are exactly like Python's dictionary methods of the same names, except that ``setdefault()`` requires both arguments (and Python is likely to change to require both arguments too -- defaulting the ``default`` argument to ``None`` has no viable use cases). Thanks to Ruslan Spivak for contributing code, tests, and documentation. - (3.6a1) Collector 1873. It wasn't possible to construct a BTree or Bucket from, or apply their update() methods to, a PersistentMapping or PersistentDict. This works now. ZopeUndo -------- - (3.6a4) Collector 1810. A previous bugfix (#1726) broke listing undoable transactions for users defined in a non-root acl_users folder. Zope logs a acl_users path together with a username (separated by a space) and this previous fix failed to take this into account. Connection ---------- - (3.6b5) An optimization for loading non-current data (MVCC) was inadvertently disabled in ``_setstate()``; this has been repaired. Documentation ------------- - (3.6b3) Thanks to Stephan Richter for converting many of the doctest files to ReST format. These are now chapters in the Zope 3 apidoc too. - (3.6b4) Several misspellings of "occurred" were repaired. Development ----------- - (3.6a1) The source code for the old ExtensionClass-based Persistence package moved, from ZODB to the Zope 2.9 development tree. ZODB 3.5 makes no use of Persistence, and, indeed, the Persistence package could not be compiled from a ZODB release, since some of the C header files needed appear only in Zope. - (3.6a3) Re-added the ``zeoctl`` module, for the same reasons ``mkzeoinst`` was re-added (see below). - (3.6a2) The ``mkzeoinst`` module was re-added to ZEO, because Zope3 has a script that expects to import it from there. ZODB's ``mkzeoinst`` script was rewritten to invoke the ``mkzeoinst`` module. ``transact`` ------------ - (3.6b4) Collector 1959: The undocumented ``transact`` module no longer worked. It remains undocumented and untested, but thanks to Janko Hauser it's possible that it works again ;-). What's new in ZODB3 3.5.1? ========================== Release date: 26-Sep-2005 Following is combined news from internal releases (to support ongoing Zope3 development). These are the dates of the internal releases: - 3.5.1b2 07-Sep-2005 - 3.5.1b1 06-Sep-2005 Build ----- - (3.5.1b2) Re-added the ``zeoctl`` module, for the same reasons ``mkzeoinst`` was re-added (see below). - (3.5.1b1) The ``mkzeoinst`` module was re-added to ZEO, because Zope3 has a script that expects to import it from there. ZODB's ``mkzeoinst`` script was rewritten to invoke the ``mkzeoinst`` module. ZopeUndo -------- - (3.5.1) Collector 1810. A previous bugfix (#1726) broke listing undoable transactions for users defined in a non-root acl_users folder. Zope logs a acl_users path together with a username (separated by a space) and this previous fix failed to take this into account. What's new in ZODB3 3.5.0? ========================== Release date: 31-Aug-2005 Following is combined news from internal releases (to support ongoing Zope3 development). These are the dates of the internal releases: - 3.5a7 11-Aug-2005 - 3.5a6 04-Aug-2005 - 3.5a5 19-Jul-2005 - 3.5a4 14-Jul-2005 - 3.5a3 17-Jun-2005 - 3.5a2 16-Jun-2005 - 3.5a1 10-Jun-2005 Savepoints ---------- - (3.5.0) As for deprecated subtransaction commits, the intent was that making a savepoint would invoke incremental garbage collection on Connection memory caches, to try to reduce the number of objects in cache to the configured cache size. Due to an oversight, this didn't happen, and stopped happening for subtransaction commits too. Making a savepoint (or doing a subtransaction commit) does invoke cache gc now. - (3.5a3) When a savepoint is made, the states of objects modified so far are saved to a temporary storage (an instance of class ``TmpStore``, although that's an internal implementation detail). That storage needs to implement the full storage API too, but was missing the ``loadBefore()`` method needed for MVCC to retrieve non-current revisions of objects. This could cause spurious errors if a transaction with a pending savepoint needed to fetch an older revision of some object. - (3.5a4) The ``ISavepoint`` interface docs said you could roll back to a given savepoint any number of times (until the transaction ends, or until you roll back to an earlier savepoint's state), but the implementation marked a savepoint as invalid after its first use. The implementation has been repaired, to match the docs. ZEO client cache ---------------- - (3.5a6) Two memory leaks in the ZEO client cache were repaired, a major one involving ``ZEO.cache.Entry`` objects, and a minor one involving empty lists. Subtransactions are deprecated ------------------------------ - (3.5a4) Subtransactions are deprecated, and will be removed in ZODB 3.7. Use savepoints instead. Savepoints are more powerful, and code using subtransactions does not mix well with code using savepoints (a subtransaction commit forces all current savepoints to become unusable, so code using subtransactions can hurt newer code trying to use savepoints). In general, a subtransaction commit done just to free memory can be changed from:: transaction.commit(1) to:: transaction.savepoint(True) That is, make a savepoint, and forget it. As shown, it's best to pass ``True`` for the optional ``optimistic`` argument in this case: because there's no possibility of asking for a rollback later, there's no need to insist that all data managers support rollback. In rarer cases, a subtransaction commit is followed later by a subtransaction abort. In that case, change the initial:: transaction.commit(1) to:: sp = transaction.savepoint() and in place of the subtransaction abort:: transaction.abort(1) roll back the savepoint instead:: sp.rollback() - (3.5a4) Internal uses of subtransactions (transaction ``commit()`` or ``abort()`` passing a true argument) were rewritten to use savepoints instead. Multi-database -------------- - (3.5a1) Preliminary support for persistent cross-database references has been added. See ``ZODB/cross-database-references.txt`` for an introduction. Tools ----- - (3.5a6, 3.5a7) Collector #1847. The ZEO client cache tracing and simulation tools weren't updated to work with ZODB 3.3, and the introduction of MVCC required major reworking of the tracing and simulation code. These tools are in a working state again, although so far lightly tested on just a few applications. In ``doc/ZEO/``, see the heavily revised ``trace.txt`` and ``cache.txt``. - (3.5a5) Collector #1846: If an uncommitted transaction was found, fsrecover.py fell into an infinite loop. Windows ------- - (3.5a6) As developed in a long thread starting at http://mail.zope.org/pipermail/zope/2005-July/160433.html there appears to be a race bug in the Microsoft Windows socket implementation, rarely visible in ZEO when multiple processes try to create an "asyncore trigger" simultaneously. Windows-specific code in ``ZEO/zrpc/trigger.py`` changed to work around this bug when it occurs. ThreadedAsync.LoopCallback -------------------------- - (3.5a5) This once again physically replaces Python's ``asyncore.loop`` function with its own loop function, because it turns out Zope relied on the seemingly unused ``LoopCallback.exit_status`` global, which was removed in the change described below. Python's ``asyncore.loop`` is again not invoked, so any breakpoints or debugging prints added to that are again "lost". - (3.5a4) This replaces Python's ``asyncore.loop`` function with its own, in order to get notified when ``loop()`` is first called. The signature of ``asyncore.loop`` changed in Python 2.4, but ``LoopCallback.loop``'s signature didn't change to match. The code here was repaired to be compatible with both old and new signatures, and also repaired to invoke Python's ``asyncore.loop()`` instead of replacing it entirely (so, for example, debugging prints added to Python's ``asyncore.loop`` won't be lost anymore). FileStorage ----------- - (3.5a4) Collector #1830. In some error cases when reading a FileStorage index, the code referenced an undefined global. - (3.5a4) Collector #1822. The ``undoLog()`` and ``undoInfo()`` methods were changed in 3.4a9 to return the documented results. Alas, some pieces of (non-ZODB) code relied on the actual behavior. When the ``first`` and ``last`` arguments are both >= 0, these methods now treat them as if they were Python slice indices, including the `first` index but excluding the ``last`` index. This matches former behavior, although it contradicts older ZODB UML documentation. The documentation in ``ZODB.interfaces.IStorageUndoable`` was changed to match the new intent. - (3.5a2) The ``_readnext()`` method now returns the transaction size as the value of the "size" key. Thanks to Dieter Maurer for the patch, from http://mail.zope.org/pipermail/zodb-dev/2003-October/006157.html. "This is very valuable when you want to spot strange transaction sizes via Zope's 'Undo' tab". BTrees ------ - (3.5.a5) Collector 1843. When a non-integer was passed to a method like ``keys()`` of a Bucket or Set with integer keys, an internal error code was overlooked, leading to everything from "delayed errors" to segfaults. Such cases raise TypeError now, as intended. - (3.5a4) Collector 1831. The BTree ``minKey()`` and ``maxKey()`` methods gave a misleading message if no key satisfying the constraints existed in a non-empty tree. - (3.5a4) Collector 1829. Clarified that the ``minKey()`` and ``maxKey()`` methods raise an exception if no key exists satsifying the constraints. - (3.5a4) The ancient ``convert.py`` script was removed. It was intended to convert "old" BTrees to "new" BTrees, but the "old" BTree implementation was removed from ZODB years ago. What's new in ZODB3 3.4.1? ========================== Release date: 09-Aug-2005 Following are dates of internal releases (to support ongoing Zope 2 development) since ZODB 3.4's last public release: - 3.4.1b5 08-Aug-2005 - 3.4.1b4 07-Aug-2005 - 3.4.1b3 04-Aug-2005 - 3.4.1b2 02-Aug-2005 - 3.4.1b1 26-Jul-2005 - 3.4.1a6 19-Jul-2005 - 3.4.1a5 12-Jul-2005 - 3.4.1a4 08-Jul-2005 - 3.4.1a3 02-Jul-2005 - 3.4.1a2 29-Jun-2005 - 3.4.1a1 27-Jun-2005 Savepoints ---------- - (3.4.1a1) When a savepoint is made, the states of objects modified so far are saved to a temporary storage (an instance of class ``TmpStore``, although that's an internal implementation detail). That storage needs to implement the full storage API too, but was missing the ``loadBefore()`` method needed for MVCC to retrieve non-current revisions of objects. This could cause spurious errors if a transaction with a pending savepoint needed to fetch an older revision of some object. - (3.4.1a5) The ``ISavepoint`` interface docs said you could roll back to a given savepoint any number of times (until the transaction ends, or until you roll back to an earlier savepoint's state), but the implementation marked a savepoint as invalid after its first use. The implementation has been repaired, to match the docs. - (3.4.1b4) Collector 1860: use an optimistic savepoint in ExportImport (there's no possiblity of rollback here, so no need to insist that the data manager support rollbacks). ZEO client cache ---------------- - (3.4.1b3) Two memory leaks in the ZEO client cache were repaired, a major one involving ``ZEO.cache.Entry`` objects, and a minor one involving empty lists. Subtransactions --------------- - (3.4.1a5) Internal uses of subtransactions (transaction ``commit()`` or ``abort()`` passing a true argument) were rewritten to use savepoints instead. Application code is strongly encouraged to do this too: subtransactions are weaker, will be deprecated soon, and do not mix well with savepoints (when you do a subtransaction commit, all current savepoints are made unusable). In general, a subtransaction commit done just to free memory can be changed from:: transaction.commit(1) to:: transaction.savepoint(True) That is, make a savepoint, and forget it. As shown, it's best to pass ``True`` for the optional ``optimistic`` argument in this case: because there's no possibility of asking for a rollback later, there's no need to insist that all data managers support rollback. In rarer cases, a subtransaction commit is followed later by a subtransaction abort. In that case, change the initial:: transaction.commit(1) to:: sp = transaction.savepoint() and in place of the subtransaction abort:: transaction.abort(1) roll back the savepoint instead:: sp.rollback() FileStorage ----------- - (3.4.1a3) Collector #1830. In some error cases when reading a FileStorage index, the code referenced an undefined global. - (3.4.1a2) Collector #1822. The ``undoLog()`` and ``undoInfo()`` methods were changed in 3.4a9 to return the documented results. Alas, some pieces of (non-ZODB) code relied on the actual behavior. When the `first` and `last` arguments are both >= 0, these methods now treat them as if they were Python slice indices, including the `first` index but excluding the `last` index. This matches former behavior, although it contradicts older ZODB UML documentation. The documentation in ``ZODB.interfaces.IStorageUndoable`` was changed to match the new intent. - (3.4.1a1) The ``UndoSearch._readnext()`` method now returns the transaction size as the value of the "size" key. Thanks to Dieter Maurer for the patch, from http://mail.zope.org/pipermail/zodb-dev/2003-October/006157.html. "This is very valuable when you want to spot strange transaction sizes via Zope's 'Undo' tab". ThreadedAsync.LoopCallback -------------------------- - (3.4.1a6) This once again physically replaces Python's ``asyncore.loop`` function with its own loop function, because it turns out Zope relied on the seemingly unused ``LoopCallback.exit_status`` global, which was removed in the change described below. Python's ``asyncore.loop`` is again not invoked, so any breakpoints or debugging prints added to that are again "lost". - (3.4.1a1) This replaces Python's ``asyncore.loop`` function with its own, in order to get notified when ``loop()`` is first called.

In ``doc/ZEO/``, see the heavily revised ``trace.txt`` and ``cache.txt``. - (3.4.1a6) Collector #1846: If an uncommitted transaction was found, fsrecover.py fell into an infinite loop. DemoStorage ----------- - (3.4.1a1) The implementation of ``undoLog()`` was wrong in several ways; repaired. BTrees ------ - (3.4.1a6) Collector 1843. When a non-integer was passed to a method like ``keys()`` of a Bucket or Set with integer keys, an internal error code was overlooked, leading to everything from "delayed errors" to segfaults. Such cases raise TypeError now, as intended. - (3.4.1a4) Collector 1831.

Clarified that the ``minKey()`` and ``maxKey()`` methods raise an exception if no key exists satsifying the constraints. What's new in ZODB3 3.4? ======================== Release date: 09-Jun-2005 Following is combined news from the "internal releases" (to support ongoing Zope 2.8 and Zope3 development) since the last public ZODB 3.4 release. These are the dates of the internal releases: - 3.4c2 06-Jun-2005 - 3.4c1 03-Jun-2005 - 3.4b3 27-May-2005 - 3.4b2 26-May-2005 Connection, DB -------------- - (3.4b3) ``.transaction_manager`` is now a public attribute of IDataManager, and is the instance of ITransactionManager used by the data manager as its transaction manager. There was previously no way to ask a data manager which transaction manager it was using. It's intended that ``transaction_manager`` be treated as read-only. - (3.4b3) For sanity, the ``txn_mgr`` argument to ``DB.open()``, ``Connection.__init__()``, and ``Connection._setDB()`` has been renamed to ``transaction_manager``. ``txn_mgr`` is still accepted, but is deprecated and will be removed in ZODB 3.6. Any code that was using the private ``._txn_mgr`` attribute of ``Connection`` will break immediately. Development ----------- - (3.4b2) ZODB's ``test.py`` is now a small driver for the shared ``zope.testing.testrunner``. See the latter's documentation for command-line arguments. Error reporting --------------- - (3.4c1) In the unlikely event that ``referencesf()`` reports an unpickling error (for example, a corrupt database can cause this), the message it produces no longer contains unprintable characters. Tests ----- - (3.4c2) ``checkCrossDBInvalidations`` suffered spurious failures too often on slow and/or busy machines. The test is willing to wait longer for success now. What's new in ZODB3 3.4b1? ========================== Release date: 19-May-2005 What follows is combined news from the "internal releases" (to support ongoing Zope 2.8 and Zope3 development) since the last public ZODB 3.4 release. These are the dates of the internal releases: - 3.4b1 19-May-2005 - 3.4a9 12-May-2005 - 3.4a8 09-May-2005 - 3.4a7 06-May-2005 - 3.4a6 05-May-2005 - 3.4a5 25-Apr-2005 - 3.4a4 23-Apr-2005 - 3.4a3 13-Apr-2005 - 3.4a2 03-Apr-2005 transaction ----------- - (3.4a7) If the first activity seen by a new ``ThreadTransactionManager`` was an explicit ``begin()`` call, then synchronizers registered after that (but still during the first transaction) were not communicated to the transaction object. As a result, the ``afterCompletion()`` methods of registered synchronizers weren't called when the first transaction ended. - (3.4a6) Doing a subtransaction commit erroneously processed invalidations, which could lead to an inconsistent view of the database. For example, let T be the transaction of which the subtransaction commit was a part. If T read a persistent object O's state before the subtransaction commit, did not commit new state of its own for O during its subtransaction commit, and O was modified before the subtransaction commit by a different transaction, then the subtransaction commit processed an invalidation for O, and the state T read for O originally was discarded in T. If T went on to access O again, it saw the newly committed (by a different transaction) state for O:: o_attr = O.some_attribute get_transaction().commit(True) assert o_attr == O.some_attribute could fail, and despite that T never modifed O. - (3.4a4) Transactions now support savepoints. Savepoints allow changes to be periodically checkpointed within a transaction. You can then rollback to a previously created savepoint. See ``transaction/savepoint.txt``. - (3.4a6) A ``getBeforeCommitHooks()`` method was added. It returns an iterable producing the registered beforeCommit hooks. - (3.4a6) The ``ISynchronizer`` interface has a new ``newTransaction()`` method. This is invoked whenever a transaction manager's ``begin()`` method is called. (Note that a transaction object's (as opposed to a transaction manager's) ``begin()`` method is deprecated, and ``newTransaction()`` is not called when using the deprecated method.) - (3.4a6) Relatedly, ``Connection`` implements ``ISynchronizer``, and ``Connection``'s ``afterCompletion()`` and ``newTransaction()`` methods now call ``sync()`` on the underlying storage (if the underlying storage has such a method), in addition to processing invalidations. The practical implication is that storage synchronization will be done automatically now, whenever a transaction is explicitly started, and after top-level transaction commit or abort. As a result, ``Connection.sync()`` should virtually never be needed anymore, and will eventually be deprecated. - (3.4a3) Transaction objects have a new method, ``beforeCommitHook(hook, *args, **kws)``. Hook functions registered with a transaction are called at the start of a top-level commit, before any of the work is begun, so a hook function can perform any database operations it likes. See ``test_beforeCommitHook()`` in ``transaction/tests/test_transaction.py`` for a tutorial doctest, and the ``ITransaction`` interface for details. Thanks to Florent Guillaume for contributing code and tests. - (3.4a3) Clarifications were made to transaction interfaces. Support for ZODB4 savepoint-aware data managers has been dropped ---------------------------------------------------------------- - (3.4a4) In adding savepoint support, we dropped the attempted support for ZODB4 data managers that support savepoints. We don't think that this will affect anyone. ZEO --- - (3.4a4) The ZODB and ZEO version numbers are now the same. Concretely:: import ZODB, ZEO assert ZODB.__version__ == ZEO.version no longer fails. If interested, see the README file for details about earlier version numbering schemes. - (3.4b1) ZConfig version 2.3 adds new socket address types, for smoother default behavior across platforms. The hostname portion of socket-binding-address defaults to an empty string, which acts like INADDR_ANY on Windows and Linux (bind to any interface). The hostname portion of socket-connection-address defaults to "127.0.0.1" (aka "localhost"). In config files, the types of ``zeo`` section keys ``address`` and ``monitor-address`` changed to socket-binding-address, and the type of the ``zeoclient`` section key ``server`` changed to socket-connection-address. - (3.4a4) The default logging setup in ``runzeo.py`` was broken. It was changed so that running ``runzeo.py`` from a command line now, and without using a config file, prints output to the console much as ZODB 3.2 did. ZEO on Windows -------------- Thanks to Mark Hammond for these ``runzeo.py`` enhancements on Windows: - (3.4b1) Collector 1788: Repair one of the new features below. - (3.4a4) A pid file (containing the process id as a decimal string) is created now for a ZEO server started via ``runzeo.py``. External programs can read the pid from this file and derive a "signal name" used in a new signal-emulation scheme for Windows. This is only necessary on Windows, but the pid file is created on all platforms that implement ``os.getpid()``, as long as the ``pid-filename`` option is set, or environment variable ``INSTANCE_HOME`` is defined. The ``pid-filename`` option can be set in a ZEO config file, or passed as the new ``--pid-file`` argument to ``runzeo.py``. - (3.4a4) If available, ``runzeo.py`` now uses Zope's new 'Signal' mechanism for Windows, to implement clean shutdown and log rotation handlers for Windows. Note that the Python in use on the ZEO server must also have the Python Win32 extensions installed for this to be useful. Tools ----- - (3.4a4) ``fsdump.py`` now displays the size (in bytes) of data records. This actually went in several months go, but wasn't noted here at the time. Thanks to Dmitry Vasiliev for contributing code and tests. FileStorage ----------- - (3.4a9) The ``undoLog()`` and ``undoInfo()`` methods almost always returned a wrong number of results, one too many if ``last < 0`` (the default is such a case), or one too few if ``last >= 0``. These have been repaired, new tests were added, and these methods are now documented in ``ZODB.interfaces.IStorageUndoable``. - (3.4a2) A ``pdb.set_trace()`` call was mistakenly left in method ``FileStorage.modifiedInVersion()``. ZConfig ------- - (3.4b1) The "standalone" release of ZODB now includes ZConfig version 2.3. DemoStorage ----------- - (3.4a4) Appropriate implementations of the storage API's ``registerDB()`` and ``new_oid()`` methods were added, delegating to the base storage. This was needed to support wrapping a ZEO client storage as a ``DemoStorage`` base storage, as some new Zope tests want to do. BaseStorage ----------- - (3.4a4) ``new_oid()``'s undocumented ``last=`` argument was removed. It was used only for internal recursion, and injured code sanity elsewhere because not all storages included it in their ``new_oid()``'s signature. Straightening this out required adding ``last=`` everywhere, or removing it everywhere. Since recursion isn't actually needed, and there was no other use for ``last=``, removing it everywhere was the obvious choice. Tests ----- - (3.4a3) The various flavors of the ``check2ZODBThreads`` and ``check7ZODBThreads`` tests are much less likely to suffer sproadic failures now. - (3.4a2) The test ``checkOldStyleRoot`` failed in Zope3, because of an obscure dependence on the ``Persistence`` package (which Zope3 doesn't use). ZApplication ------------ - (3.4a8) The file ``ZApplication.py`` was moved, from ZODB to Zope(2). ZODB and Zope3 don't use it, but Zope2 does. - (3.4a7) The ``__call__`` method didn't work if a non-None ``connection`` string argument was passed. Thanks to Stefan Holek for noticing. What's new in ZODB3 3.4a1? ========================== Release date: 01-Apr-2005 transaction ----------- - ``get_transaction()`` is officially deprecated now, and will be removed in ZODB 3.6. Use the ``transaction`` package instead. For example, instead of:: import ZODB ... get_transaction().commit() do:: import transaction ... transaction.commit() DB -- - There is no longer a hard limit on the number of connections that ``DB.open()`` will create. In other words, ``DB.open()`` never blocks anymore waiting for an earlier connection to close, and ``DB.open()`` always returns a connection now (while it wasn't documented, it was possible for ``DB.open()`` to return ``None`` before). ``pool_size`` continues to default to 7, but its meaning has changed: if more than ``pool_size`` connections are obtained from ``DB.open()`` and not closed, a warning is logged; if more than twice ``pool_size``, a critical problem is logged. ``pool_size`` should be set to the maximum number of connections from the ``DB`` instance you expect to have open simultaneously. In addition, if a connection obtained from ``DB.open()`` becomes unreachable without having been explicitly closed, when Python's garbage collection reclaims that connection it no longer counts against the ``pool_size`` thresholds for logging messages. The following optional arguments to ``DB.open()`` are deprecated: ``transaction``, ``waitflag``, ``force`` and ``temporary``. If one is specified, its value is ignored, and ``DeprecationWarning`` is raised. In ZODB 3.6, these optional arguments will be removed. - Lightweight support for "multi-databases" is implemented. These are collections of named DB objects and associated open Connections, such that the Connection for any DB in the collection can be obtained from a Connection from any other DB in the collection. See the new test file ZODB/tests/multidb.txt for a tutorial doctest. Thanks to Christian Theune for his work on this during the PyCon 2005 ZODB sprint. ZEO compatibility ----------------- There are severe restrictions on using ZEO servers and clients at or after ZODB 3.3 with ZEO servers and clients from ZODB versions before 3.3. See the reworked ``Compatibility`` section in ``README.txt`` for details. If possible, it will be easiest to move clients and servers to 3.3+ simultaneously. With care, it's possible to use a 3.3+ ZEO server with pre-3.3 ZEO clients, but not possible to use a pre-3.3 ZEO server with 3.3+ ZEO clients. BTrees ------ - A new family of BTree types, in the ``IFBTree`` module, map signed integers (32 bits) to C floats (also 32 bits). The intended use is to help construct search indices, where, e.g., integer word or document identifiers map to scores of some kind. This is easier than trying to work with scaled integer scores in an ``IIBTree``, and Zope3 has moved to ``IFBTrees`` for these purposes in its search code. FileStorage ----------- - Addded a record iteration protocol to FileStorage. You can use the record iterator to iterate over all current revisions of data pickles in the storage. In order to support calling via ZEO, we don't implement this as an actual iterator. An example of using the record iterator protocol is as follows:: storage = FileStorage('anexisting.fs') next_oid = None while True: oid, tid, data, next_oid = storage.record_iternext(next_oid) # do something with oid, tid and data if next_oid is None: break The behavior of the iteration protocol is now to iterate over all current records in the database in ascending oid order, although this is not a promise to do so in the future. Tools ----- New tool fsoids.py, for heavy debugging of FileStorages; shows all uses of specified oids in the entire database (e.g., suppose oid 0x345620 is missing -- did it ever exist? if so, when? who referenced it? when was the last transaction that modified an object that referenced it? which objects did it reference? what kind of object was it?). ZODB/test/testfsoids.py is a tutorial doctest. fsIndex ------- Efficient, general implementations of ``minKey()`` and ``maxKey()`` methods were added. ``fsIndex`` is a special hybrid kind of BTree used to implement FileStorage indices. Thanks to Chris McDonough for code and tests. What's new in ZODB3 3.3.1? ========================== Release date: DD-MMM-2005 Tests ----- The various flavors of the ``check2ZODBThreads`` and ``check7ZODBThreads`` tests are much less likely to suffer sproadic failures now. What's new in ZODB3 3.3.1c1? ============================ Release date: 01-Apr-2005 BTrees ------ Collector #1734: BTrees conflict resolution leads to index inconsistencies. Silent data loss could occur due to BTree conflict resolution when one transaction T1 added a new key to a BTree containing at least three buckets, and a concurrent transaction T2 deleted all keys in the bucket to which the new key was added. Conflict resolution then created a bucket containing the newly added key, but the bucket remained isolated, disconnected from the BTree. In other words, the committed BTree didn't contain the new key added by T1. Conflict resolution doesn't have enough information to repair this, so ``ConflictError`` is now raised in such cases. ZEO --- Repaired subtle race conditions in establishing ZEO connections, both client- and server-side. These account for intermittent cases where ZEO failed to make a connection (or reconnection), accompanied by a log message showing an error caught in ``asyncore`` and having a traceback ending with: ``UnpicklingError: invalid load key, 'Z'.`` or: ``ZRPCError: bad handshake '(K\x00K\x00U\x0fgetAuthProtocol)t.'`` or: ``error: (9, 'Bad file descriptor')`` or an ``AttributeError``. These were exacerbated when running the test suite, because of an unintended busy loop in the test scaffolding, which could starve the thread trying to make a connection. The ZEO reconnection tests may run much faster now, depending on platform, and should suffer far fewer (if any) intermittent "timed out waiting for storage to connect" failures. ZEO protocol and compatibility ------------------------------ ZODB 3.3 introduced multiversion concurrency control (MVCC), which required changes to the ZEO protocol. The first 3.3 release should have increased the internal ZEO protocol version number (used by ZEO protocol negotiation when a client connects), but neglected to. This has been repaired. Compatibility between pre-3.3 and post-3.3 ZEO clients and servers remains very limited. See the newly updated ``Compatibility`` section in ``README.txt`` for details. FileStorage ----------- - The ``.store()`` and ``.restore()`` methods didn't update the storage's belief about the largest oid in use when passed an oid larger than the largest oid the storage already knew about. Because ``.restore()`` in particular is used by ``copyTransactionsFrom()``, and by the first stage of ZRS recovery, a large database could be created that believed the only oid in use was oid 0 (the special oid reserved for the root object). In rare cases, it could go on from there assigning duplicate oids to new objects, starting over from oid 1 again. This has been repaired. A new ``set_max_oid()`` method was added to the ``BaseStorage`` class so that derived storages can update the largest oid in use in a threadsafe way. - A FileStorage's index file tried to maintain the index's largest oid as a separate piece of data, incrementally updated over the storage's lifetime. This scheme was more complicated than necessary, so was also more brittle and slower than necessary. It indirectly participated in a rare but critical bug: when a FileStorage was created via ``copyTransactionsFrom()``, the "maximum oid" saved in the index file was always 0. Use that FileStorage, and it could then create "new" oids starting over at 0 again, despite that those oids were already in use by old objects in the database. Packing a FileStorage has no reason to try to update the maximum oid in the index file either, so this kind of damage could (and did) persist even across packing. The index file's maximum-oid data is ignored now, but is still written out so that ``.index`` files can be read by older versions of ZODB. Finding the true maximum oid is done now by exploiting that the main index is really a kind of BTree (long ago, this wasn't true), and finding the largest key in a BTree is inexpensive. - A FileStorage's index file could be updated on disk even if the storage was opened in read-only mode. That bug has been repaired. - An efficient ``maxKey()`` implementation was added to class ``fsIndex``. Pickle (in-memory Connection) Cache ----------------------------------- You probably never saw this exception: ``ValueError: Can not re-register object under a different oid`` It's been changed to say what it meant: ``ValueError: A different object already has the same oid`` This happens if an attempt is made to add distinct objects to the cache that have the same oid (object identifier). ZODB should never do this, but it's possible for application code to force such an attempt. PersistentMapping and PersistentList ------------------------------------ Backward compatibility code has been added so that the sanest of the ZODB 3.2 dotted paths for ``PersistentMapping`` and ``PersistentList`` resolve. These are still preferred: - ``from persistent.list import PersistentList`` - ``from persistent.mapping import PersistentMapping`` but these work again too: - ``from ZODB.PersistentList import PersistentList`` - ``from ZODB.PersistentMapping import PersistentMapping`` BTrees ------ The BTrees interface file neglected to document the optional ``excludemin`` and ``excludemax`` arguments to the ``keys()``, ``values()`` and ``items()`` methods. Appropriate changes were merged in from the ZODB4 BTrees interface file. Tools ----- - ``mkzeoinst.py``'s default port number changed from to 9999 to 8100, to match the example in Zope's ``zope.conf``. fsIndex ------- An efficient ``maxKey()`` method was implemented for the ``fsIndex`` class. This makes it possible to determine the largest oid in a ``FileStorage`` index efficiently, directly, and reliably, replacing a more delicate scheme that tried to keep track of this by saving an oid high water mark in the index file and incrementally updating it. What's new in ZODB3 3.3.1a1? ============================ Release date: 11-Jan-2005 ZEO client cache ---------------- - Collector 1536: The ``cache-size`` configuration option for ZEO clients was being ignored. Worse, the client cache size was only one megabyte, much smaller than the advertised default of 20MB. Note that the default is carried over from a time when gigabyte disks were expensive and rare; 20MB is also too small on most modern machines. - Fixed a nasty bug in cache verification. A persistent ZEO cache uses a disk file, and, when active, has some in-memory data structures too to speed operation. Invalidations processed as part of startup cache verification were reflected in the in-memory data structures, but not correctly in the disk file. So if an object revision was invalidated as part of verification, the object wasn't loaded again before the connection was closed, and the object revision remained in the cache file until the connection was closed, then the next time the cache file was opened it could believe that the stale object revision in the file was actually current. - Fixed a bug wherein an object removed from the client cache didn't properly mark the file slice it occupied as being available for reuse. ZEO --- Collector 1503: excessive logging. It was possible for a ZEO client to log "waiting for cache verification to finish" messages at a very high rate, producing gigabytes of such messages in short order. ``ClientStorage._wait_sync()`` was changed to log no more than one such message per 5 minutes. persistent ---------- Collector #1350: ZODB has a default one-thread-per-connection model, and two threads should never do operations on a single connection simultaneously. However, ZODB can't detect violations, and this happened in an early stage of Zope 2.8 development. The low-level ``ghostify()`` and ``unghostify()`` routines in ``cPerisistence.c`` were changed to give some help in detecting this when it happens. In a debug build, both abort the process if thread interference is detected. This is extreme, but impossible to overlook. In a release build, ``unghostify()`` raises ``SystemError`` if thread damage is detected; ``ghostify()`` ignores the problem in a release build (``ghostify()`` is supposed to be so simple that it "can't fail"). ConflictError ------------- New in 3.3, a ``ConflictError`` exception may attempt to insert the path to the object's class in its message. However, a ZEO server may not have access to application class implementations, and then the attempt by the server to raise ``ConflictError`` could raise ``ImportError`` instead while trying to determine the object's class path. This was confusing. The code has been changed to obtain the class path from the object's pickle, without trying to import application modules or classes. FileStorage ----------- Collector 1581: When an attempt to pack a corrupted ``Data.fs`` file was made, it was possible for the pack routine to die with a reference to an undefined global while it was trying to raise ``CorruptedError``. It raises ``CorruptedError``, as it always intended, in these cases now. Install ------- The C header file ``ring.h`` is now installed. Tools ----- - ``BTrees.check.display()`` now displays the oids (if any) of the BTree's or TreeSet's constituent objects. What's new in ZODB3 3.3? ======================== Release date: 06-Oct-2004 ZEO --- The encoding of RPC calls between server and client was being done with protocol 0 ("text mode") pickles, which could require sending four times as many bytes as necessary. Protocol 1 pickles are used now. Thanks to Andreas Jung for the diagnosis and cure. ZODB/component.xml ------------------ ``cache-size`` parameters were changed from type ``integer`` to type ``byte-size``. This allows you to specify, for example, "``cache-size 20MB``" to get a 20 megabyte cache. transaction ----------- The deprecation warning for ``Transaction.begin()`` was changed to point to the caller, instead of to ``Transaction.begin()`` itself. Connection ---------- Restored Connection's private ``_opened`` attribute. This was still referenced by ``DB.connectionDebugInfo()``, and Zope 2 calls the latter. FileStorage ----------- Collector #1517: History tab for ZPT does not work. ``FileStorage.history()`` was reading the user, description, and extension fields out of the object pickle, due to starting the read at a wrong location. Looked like cut-and-paste repetition of the same bug in ``FileStorage.FileIterator`` noted in the news for 3.3c1. What's new in ZODB3 3.3 release candidate 1? ============================================ Release date: 14-Sep-2004 Connection ---------- ZODB intends to raise ``ConnnectionStateError`` if an attempt is made to close a connection while modifications are pending (the connection is involved in a transaction that hasn't been ``abort()``'ed or ``commit()``'ed). It was missing the case where the only pending modifications were made in subtransactions. This has been fixed. If an attempt to close a connection with pending subtransactions is made now:: ConnnectionStateError: Cannot close a connection with a pending subtransaction is raised. transaction ----------- - Transactions have new, backward-incompatible behavior in one respect: if a ``Transaction.commit()``, ``Transaction.commit(False)``, or ``Transaction.commit(True)`` raised an exception, prior behavior was that the transaction effectively aborted, and a new transaction began. A primary bad consequence was that, if in a sequence of subtransaction commits, one of the commits failed but the exception was suppressed, all changes up to and including the failing commit were lost, but later subtransaction commits in the sequence got no indication that something had gone wrong, nor did the final (top level) commit. This could easily lead to inconsistent data being committed, from the application's point of view. The new behavior is that a failing commit "sticks" until explicitly cleared. Now if an exception is raised by a ``commit()`` call (whether subtransaction or top level) on a Transaction object ``T``: - Pending changes are aborted, exactly as they were for a failing commit before. - But ``T`` remains the current transaction object (if ``tm`` is ``T``'s transaction manger, ``tm.get()`` continues to return ``T``). - All subsequent attempts to do ``T.commit()``, ``T.join()``, or ``T.register()`` raise the new ``TransactionFailedError`` exception. Note that if you try to modify a persistent object, that object's resource manager (usually a ``Connection`` object) will attempt to ``join()`` the failed transaction, and ``TransactionFailedError`` will be raised right away. So after a transaction or subtransaction commit fails, that must be explicitly cleared now, either by invoking ``abort()`` on the transaction object, or by invoking ``begin()`` on its transaction manager. - Some explanations of new transaction features in the 3.3a3 news were incorrect, and this news file has been retroactively edited to repair that. See news for 3.3a3 below. - If ReadConflictError was raised by an attempt to load an object with a ``_p_independent()`` method that returned false, attempting to commit the transaction failed to (re)raise ReadConflictError for that object. Note that ZODB intends to prevent committing a transaction in which a ReadConflictError occurred; this was an obscure case it missed. - Growing pains: ZODB 3.2 had a bug wherein ``Transaction.begin()`` didn't abort the current transaction if the only pending changes were in a subtransaction. In ZODB 3.3, it's intended that a transaction manager be used to effect ``begin()`` (instead of invoking ``Transaction.begin()``), and calling ``begin()`` on a transaction manager didn't have this old bug. However, ``Transaction.begin()`` still exists in 3.3, and it had a worse bug: it never aborted the transaction (not even if changes were pending outside of subtransactions). ``Transaction.begin()`` has been changed to abort the transaction. ``Transaction.begin()`` is also deprecated. Don't use it. Use ``begin()`` on the relevant transaction manager instead. For example, >>> import transaction >>> txn = transaction.begin() # start a txn using the default TM if using the default ``ThreadTransactionManager`` (see news for 3.3a3 below). In 3.3, it's intended that a single ``Transaction`` object is used for exactly one transaction. So, unlike as in 3.2, when somtimes ``Transaction`` objects were reused across transactions, but sometimes weren't, when you do ``Transaction.begin()`` in 3.3 a brand new transaction object is created. That's why this use is deprecated. Code of the form: >>> txn = transaction.get() >>> ... >>> txn.begin() >>> ... >>> txn.commit() can't work as intended in 3.3, because ``txn`` is no longer the current ``Transaction`` object the instant ``txn.begin()`` returns. BTrees ------ The BTrees __init__.py file is now just a comment. It had been trying to set up support for (long gone) "int sets", and to import an old version of Zope's Interface package, which doesn't even ship with ZODB. The latter in particular created problems, at least clashing with PythonCAD's Interface package. POSException ------------ Collector #1488 (TemporaryStorage -- going backward in time). This confusion was really due to that the detail on a ConflictError exception didn't make sense. It called the current revision "was", and the old revision "now". The detail is much more informative now. For example, if the exception said:: ConflictError: database conflict error (oid 0xcb22, serial was 0x03441422948b4399, now 0x034414228c3728d5) before, it now says:: ConflictError: database conflict error (oid 0xcb22, serial this txn started with 0x034414228c3728d5 2002-04-14 20:50:32.863000, serial currently committed 0x03441422948b4399 2002-04-14 20:50:34.815000) ConflictError ------------- The undocumented ``get_old_serial()`` and ``get_new_serial()`` methods were swapped (the first returned the new serial, and the second returned the old serial). Tools ----- ``FileStorage.FileIterator`` was confused about how to read a transaction's user and description fields, which caused several tools to display binary gibberish for these values. ``ZODB.utils.oid_repr()`` changed to add a leading "0x", and to strip leading zeroes. This is used, e.g., in the detail of a ``POSKeyError`` exception, to identify the missing oid. Before, the output was ambiguous. For example, oid 17 was displayed as 0000000000000011. As a Python integer, that's octal 9. Or was it meant to be decimal 11? Or was it meant to be hex? Now it displays as 0x11. fsrefs.py: When run with ``-v``, produced tracebacks for objects whose creation was merely undone. This was confusing. Tracebacks are now produced only if there's "a real" problem loading an oid. If the current revision of object O refers to an object P whose creation has been undone, this is now identified as a distinct case. Captured and ignored most attempts to stop it via Ctrl+C. Repaired. Now makes two passes, so that an accurate report can be given of all invalid references. ``analyze.py`` produced spurious "len of unsized object" messages when finding a data record for an object uncreation or version abort. These no longer appear. ``fsdump.py``'s ``get_pickle_metadata()`` function (which is used by several tools) was confused about what to do when the ZODB pickle started with a pickle ``GLOBAL`` opcode. It actually loaded the class then, which it intends never to do, leading to stray messages on stdout when the class wasn't available, and leading to a strange return value even when it was available (the repr of the type object was returned as "the module name", and an empty string was returned as "the class name"). This has been repaired. What's new in ZODB3 3.3 beta 2 ============================== Release date: 13-Aug-2004 Transaction Managers -------------------- Zope3-dev Collector #139: Memory leak involving buckets and connections The transaction manager internals effectively made every Connection object immortal, except for those explicitly closed. Since typical practice is not to close connections explicitly (and closing a DB happens not to close the connections to it -- although that may change), this caused massive memory leaks when many connections were opened. The transaction manager internals were reworked to use weak references instead, so that connection memory (and other registered synch objects) now get cleaned up when nothing other than the transaction manager knows about them. Storages -------- Collector #1327: FileStorage init confused by time travel If the system clock "went backwards" a long time between the times a FileStorage was closed and reopened, new transaction ids could be smaller than transaction ids already in the storage, violating a key invariant. Now transaction ids are guaranteed to be increasing even when this happens. If time appears to have run backwards at all when a FileStorage is opened, a new message saying so is logged at warning level; if time appears to have run backwards at least 30 minutes, the message is logged at critical level (and you should investigate to find and repair the true cause). Tools ----- repozo.py: Thanks to a suggestion from Toby Dickenson, backups (whether incremental or full) are first written to a temp file now, which is fsync'ed at the end, and only after that succeeds is the file renamed to YYYY-MM-DD-HH-MM-SS.ext form. In case of a system crash during a repozo backup, this at least makes it much less likely that a backup file with incomplete or incorrect data will be left behind. fsrefs.py: Fleshed out the module docstring, and repaired a bug wherein spurious error msgs could be produced after reporting a problem with an unloadable object. Test suite ---------- Collector #1397: testTimeStamp fails on FreeBSD The BSD distributions are unique in that their mktime() implementation usually ignores the input tm_isdst value. Test checkFullTimeStamp() was sensitive to this platform quirk. Reworked the way some of the ZEO tests use threads, so that unittest is more likely to notice the real cause of a failure (which usually occurs in a thread), and less likely to latch on to spurious problems resulting from the real failure. What's new in ZODB3 3.3 beta 1 ============================== Release date: 07-Jun-2004 3.3b1 is the first ZODB release built using the new zpkg tools: http://zope.org/Members/fdrake/zpkgtools/ This appears to have worked very well. The structure of the tarball release differs from previous releases because of it, and the set of installed files includes some that were not installed in previous releases. That shouldn't create problems, so let us know if it does! We'll fine-tune this for the next release. BTrees ------ Fixed bug indexing BTreeItems objects with negative indexes. This caused reverse iteration to return each item twice. Thanks to Casey Duncan for the fix. ZODB ---- Methods removed from the database (ZODB.DB.DB) class: cacheStatistics(), cacheMeanAge(), cacheMeanDeac(), and cacheMeanDeal(). These were undocumented, untested, and unused. The first always returned an empty tuple, and the rest always returned None. When trying to do recovery to a time earlier than that of the most recent full backup, repozo.py failed to find the appropriate files, erroneously claiming "No files in repository before ". This has been repaired. Collector #1330: repozo.py -R can create corrupt .fs. When looking for the backup files needed to recreate a Data.fs file, repozo could (unintentionally) include its meta .dat files in the list, or random files of any kind created by the user in the backup directory. These would then get copied verbatim into the reconstructed file, filling parts with junk. Repaired by filtering the file list to include only files with the data extensions repozo.py creates (.fs, .fsz, .deltafs, and .deltafsz). Thanks to James Henderson for the diagnosis. fsrecover.py couldn't work, because it referenced attributes that no longer existed after the MVCC changes. Repaired that, and added new tests to ensure it continues working. Collector #1309: The reference counts reported by DB.cacheExtremeDetails() for ghosts were one too small. Thanks to Dieter Maurer for the diagnosis. Collector #1208: Infinite loop in cPickleCache. If a persistent object had a __del__ method (probably not a good idea regardless, but we don't prevent it) that referenced an attribute of self, the code to deactivate objects in the cache could get into an infinite loop: ghostifying the object could lead to calling its __del__ method, the latter would load the object into cache again to satsify the attribute reference, the cache would again decide that the object should be ghostified, and so on. The infinite loop no longer occurs, but note that objects of this kind still aren't sensible (they're effectively immortal). Thanks to Toby Dickenson for suggesting a nice cure. What's new in ZODB3 3.3 alpha 3 =============================== Release date: 16-Apr-2004 transaction ----------- There is a new transaction package, which provides new interfaces for application code and for the interaction between transactions and resource managers. The top-level transaction package has functions ``commit()``, ``abort()``, ``get()``, and ``begin()``. They should be used instead of the magic ``get_transaction()`` builtin, which will be deprecated. For example: >>> get_transaction().commit() should now be written as >>> import transaction >>> transaction.commit() The new API provides explicit transaction manager objects. A transaction manager (TM) is responsible for associating resource managers with a "current" transaction. The default TM, implemented by class ``ThreadedTransactionManager``, assigns each thread its own current transaction. This default TM is available as ``transaction.manager``. The ``TransactionManager`` class assigns all threads to the same transaction, and is an explicit replacement for the ``Connection.setLocalTransaction()`` method: A transaction manager instance can be passed as the transaction_manager argument to ``DB.open()``. If you do, the connection will use the specified transaction manager instead of the default TM. The current transaction is obtained by calling ``get()`` on a TM. For example: >>> tm = transaction.TransactionManager() >>> cn = db.open(transaction_manager=tm) [...] >>> tm.get().commit() The ``setLocalTransaction()`` and ``getTransaction()`` methods of Connection are deprecated. Use an explicit TM passed via ``transaction_manager=`` to ``DB.open()`` instead. The ``setLocalTransaction()`` method still works, but it returns a TM instead of a Transaction. A TM creates Transaction objects, which are used for exactly one transaction. Transaction objects still have ``commit()``, ``abort()``, ``note()``, ``setUser()``, and ``setExtendedInfo()`` methods. Resource managers, e.g. Connection or RDB adapter, should use a Transaction's ``join()`` method instead of its ``register()`` method. An object that calls ``join()`` manages its own resources. An object that calls ``register()`` expects the TM to manage the objects. Data managers written against the ZODB 4 transaction API are now supported in ZODB 3. persistent ---------- A database can now contain persistent weak references. An object that is only reachable from persistent weak references will be removed by pack(). The persistence API now distinguishes between deactivation and invalidation. This change is intended to support objects that can't be ghosts, like persistent classes. Deactivation occurs when a user calls _p_deactivate() or when the cache evicts objects because it is full. Invalidation occurs when a transaction updates the object. An object that can't be a ghost must load new state when it is invalidated, but can ignore deactivation. Persistent objects can implement a __getnewargs__() method that will be used to provide arguments that should be passed to __new__() when instances (including ghosts) are created. An object that implements __getnewargs__() must be loaded from storage even to create a ghost. There is new support for writing hooks like __getattr__ and __getattribute__. The new hooks require that user code call special persistence methods like _p_getattr() inside their hook. See the ZODB programming guide for details. The format of serialized persistent references has changed; that is, the on-disk format for references has changed. The old format is still supported, but earlier versions of ZODB will not be able to read the new format. ZODB ---- Closing a ZODB Connection while it is registered with a transaction, e.g. has pending modifications, will raise a ConnnectionStateError. Trying to load objects from or store objects to a closed connection will also raise a ConnnectionStateError. ZODB connections are synchronized on commit, even when they didn't modify objects. This feature assumes that the thread that opened the connection is also the thread that uses it. If not, this feature will cause problems. It can be disabled by passing synch=False to open(). New broken object support. New add() method on Connection. User code should not assign the _p_jar attribute of a new persistent object directly; a deprecation warning is issued in this case. Added a get() method to Connection as a preferred synonym for __getitem__(). Several methods and/or specific optional arguments of methods have been deprecated. The cache_deactivate_after argument used by DB() and Connection() is deprecated. The DB methods getCacheDeactivateAfter(), getVersionCacheDeactivateAfter(), setCacheDeactivateAfter(), and setVersionCacheDeactivateAfter() are also deprecated. The old-style undo() method was removed from the storage API, and transactionalUndo() was renamed to undo(). The BDBStorages are no longer distributed with ZODB. Fixed a serious bug in the new pack implementation. If pack was called on the storage and passed a time earlier than a previous pack time, data could be lost. In other words, if there are any two pack calls, where the time argument passed to the second call was earlier than the first call, data loss could occur. The bug was fixed by causing the second call to raise a StorageError before performing any work. Fixed a rare bug in pack: if a pack started during a small window of time near the end of a concurrent transaction's commit, it was possible for the pack attempt to raise a spurious CorruptedError: ... transaction with checkpoint flag set exception. This did no damage to the database, or to the transaction in progress, but no pack was performed then. By popular demand, FileStorage.pack() no longer propagates a FileStorageError: The database has already been packed to a later time or no changes have been made since the last pack exception. Instead that message is logged (at INFO level), and the pack attempt simply returns then (no pack is performed). ZEO --- Fixed a bug that prevented the -m / --monitor argument from working. zdaemon ------- Added a -m / --mask option that controls the umask of the subprocess. zLOG ---- The zLOG backend has been removed. zLOG is now just a facade over the standard Python logging package. Environment variables like STUPID_LOG_FILE are no longer honored. To configure logging, you need to follow the directions in the logging package documentation. The process is currently more complicated than configured zLOG. See test.py for an example. ZConfig ------- This release of ZODB contains ZConfig 2.1. More documentation has been written. Make sure keys specified as attributes of the element are converted by the appropriate key type, and are re-checked for derived sections. Refactored the ZConfig.components.logger schema components so that a schema can import just one of the "eventlog" or "logger" sections if desired. This can be helpful to avoid naming conflicts. Added a reopen() method to the logger factories. Always use an absolute pathname when opening a FileHandler. Miscellaneous ------------- The layout of the ZODB source release has changed. All the source code is contained in a src subdirectory. The primary motivation for this change was to avoid confusion caused by installing ZODB and then testing it interactively from the source directory; the interpreter would find the uncompiled ZODB package in the source directory and report an import error. A reference-counting bug was fixed, in the logic calling a modified persistent object's data manager's register() method. The primary symptom was rare assertion failures in Python's cyclic garbage collection. The Connection class's onCommitAction() method was removed. Some of the doc strings in ZODB are now written for processing by epydoc. Several new test suites were written using doctest instead of the standard unittest TestCase framework. MappingStorage now implements getTid(). ThreadedAsync: Provide a way to shutdown the servers using an exit status. The mkzeoinstance script looks for a ZODB installation, not a Zope installation. The received wisdom is that running a ZEO server without access to the appserver code avoids many mysterious problems. What's new in ZODB3 3.3 alpha 2 =============================== Release date: 06-Jan-2004 This release contains a major overhaul of the persistence machinery, including some user-visible changes. The Persistent base class is now a new-style class instead of an ExtensionClass. The change enables the use of features like properties with persistent object classes. The Persistent base class is now contained in the persistent package. The Persistence package is included for backwards compatibility. The Persistence package is used by Zope to provide special ExtensionClass-compatibility features like a non-C3 MRO and an __of__ method. ExtensionClass is not included with this release of ZODB3. If you use the Persistence package, it will print a warning and import Persistent from persistent. In short, the new persistent package is recommended for non-Zope applications. The following dotted class names are now preferred over earlier names: - persistent.Persistent - persistent.list.PersistentList - persistent.mapping.PersistentMapping - persistent.TimeStamp The in-memory, per-connection object cache (pickle cache) was changed to participate in garbage collection. This should reduce the number of memory leaks, although we are still tracking a few problems. Multi-version concurrency control --------------------------------- ZODB now supports multi-version concurrency control (MVCC) for storages that support multiple revisions. FileStorage and BDBFullStorage both support MVCC. In short, MVCC means that read conflicts should almost never occur. When an object is modified in one transaction, other concurrent transactions read old revisions of the object to preserve consistency. In earlier versions of ZODB, any access of the modified object would raise a ReadConflictError. The ZODB internals changed significantly to accommodate MVCC. There are relatively few user visible changes, aside from the lack of read conflicts. It is possible to disable the MVCC feature using the mvcc keyword argument to the DB open() method, ex.: db.open(mvcc=False). ZEO --- Changed the ZEO server and control process to work with a single configuration file; this is now the default way to configure these processes. (It's still possible to use separate configuration files.) The ZEO configuration file can now include a "runner" section used by the control process and ignored by the ZEO server process itself. If present, the control process can use the same configuration file. Fixed a performance problem in the logging code for the ZEO protocol. The logging code could call repr() on arbitrarily long lists, even though it only logged the first 60 bytes; worse, it called repr() even if logging was currently disabled. Fixed to call repr() on individual elements until the limit is reached. Fixed a bug in zrpc (when using authentication) where the MAC header wasn't being read for large messages, generating errors while unpickling commands sent over the wire. Also fixed the zeopasswd.py script, added testcases and provided a more complete commandline interface. Fixed a misuse of the _map variable in zrpc Connectio objects, which are also asyncore.dispatcher objects. This allows ZEO to work with CVS Python (2.4). _map is used to indicate whether the dispatcher users the default socket_map or a custom socket_map. A recent change to asyncore caused it to use _map in its add_channel() and del_channel() methods, which presumes to be a bug fix (may get ported to 2.3). That causes our dubious use of _map to be a problem, because we also put the Connections in the global socket_map. The new asyncore won't remove it from the global socket map, because it has a custom _map. The prefix used for log messages from runzeo.py was changed from RUNSVR to RUNZEO. Miscellaneous ------------- ReadConflictError objects now have an ignore() method. Normally, a transaction that causes a read conflict can't be committed. If the exception is caught and its ignore() method called, the transaction can be committed. Application code may need this in advanced applications. What's new in ZODB3 3.3 alpha 1 =============================== Release date: 17-Jul-2003 New features of Persistence --------------------------- The Persistent base class is a regular Python type implemented in C. It should be possible to create new-style classes that inherit from Persistent, and, thus, use all the new Python features introduced in Python 2.2 and 2.3. The __changed__() method on Persistent objects is no longer supported. New features in BTrees ---------------------- BTree, Bucket, TreeSet and Set objects are now iterable objects, playing nicely with the iteration protocol introduced in Python 2.2, and can be used in any context that accepts an iterable object. As for Python dicts, the iterator constructed for BTrees and Buckets iterates over the keys. >>> from BTrees.OOBTree import OOBTree >>> b = OOBTree({"one": 1, "two": 2, "three": 3, "four": 4}) >>> for key in b: # iterates over the keys ... print key four one three two >>> list(enumerate(b)) [(0, 'four'), (1, 'one'), (2, 'three'), (3, 'two')] >>> i = iter(b) >>> i.next() 'four' >>> i.next() 'one' >>> i.next() 'three' >>> i.next() 'two' >>> As for Python dicts in 2.2, BTree and Bucket objects have new .iterkeys(), .iteritems(), and .itervalues() methods. TreeSet and Set objects have a new .iterkeys() method. Unlike as for Python dicts, these new methods accept optional min and max arguments to effect range searches. While Bucket.keys() produces a list, Bucket.iterkeys() produces an iterator, and similarly for Bucket values() versus itervalues(), Bucket items() versus iteritems(), and Set keys() versus iterkeys(). The iter{keys,values,items} methods of BTrees and the iterkeys() method of Treesets also produce iterators, while their keys() (etc) methods continue to produce BTreeItems objects (a form of "lazy" iterator that predates Python 2.2's iteration protocol). >>> sum(b.itervalues()) 10 >>> zip(b.itervalues(), b.iterkeys()) [(4, 'four'), (1, 'one'), (3, 'three'), (2, 'two')] >>> BTree, Bucket, TreeSet and Set objects also implement the __contains__ method new in Python 2.2, which means that testing for key membership can be done directly now via the "in" and "not in" operators: >>> "won" in b False >>> "won" not in b True >>> "one" in b True >>> All old and new range-search methods now accept keyword arguments, and new optional excludemin and excludemax keyword arguments. The new keyword arguments allow doing a range search that's exclusive at one or both ends (doesn't include min, and/or doesn't include max). >>> list(b.keys()) ['four', 'one', 'three', 'two'] >>> list(b.keys(max='three')) ['four', 'one', 'three'] >>> list(b.keys(max='three', excludemax=True)) ['four', 'one'] >>> Other improvements ------------------ The exceptions generated by write conflicts now contain the name of the conflicted object's class. This feature requires support for the storage. All the standard storages support it. What's new in ZODB3 3.2 ======================== Release date: 08-Oct-2003 Nothing has changed since release candidate 1. What's new in ZODB3 3.2 release candidate 1 =========================================== Release date: 01-Oct-2003 Added a summary to the Doc directory. There are several new documents in the 3.2 release, including "Using zdctl and zdrun to manage server processes" and "Running a ZEO Server HOWTO." Fixed ZEO's protocol negotiation mechanism so that a client ZODB 3.1 can talk to a ZODB 3.2 server. Fixed a memory leak in the ZEO server. The server was leaking a few KB of memory per connection. Fixed a memory leak in the ZODB object cache (cPickleCache). The cache did not release two references to its Connection, causing a large cycle of objects to leak when a database was closed. Fixed a bug in the ZEO code that caused it to leak socket objects on Windows. Specifically, fix the trigger mechanism so that both sockets created for a trigger are closed. Fixed a bug in the ZEO storage server that caused it to leave temp files behind. The CommitLog class contains a temp file, but it was not closing the file. Changed the order of setuid() and setgid() calls in zdrun, so that setgid() is called first. Added a timeout to the ZEO test suite that prevents hangs. The test suite creates ZEO servers with randomly assigned ports. If the port happens to be in use, the test suite would hang because the ZEO client would never stop trying to connect. The fix will cause the test to fail after a minute, but should prevent the test runner from hanging. The logging package was updated to include the latest version of the logging package from Python CVS. Note that this package is only installed for Python 2.2. In later versions of Python, it is available in the Python standard library. The ZEO1 directory was removed from the source distribution. ZEO1 is not supported, and we never intended to include it in the release. What's new in ZODB3 3.2 beta 3 ============================== Release date: 23-Sep-2003 Note: The changes listed for this release include changes also made in ZODB 3.1.x releases and ported to the 3.2 release. This version of ZODB 3.2 is not compatible with Python 2.1. Early versions were explicitly designed to be compatible with Zope 2.6. That plan has been dropped, because Zope 2.7 is already in beta release. Several of the classes in ZEO and ZODB now inherit from object, making them new-style classes. The primary motivation for the change was to make it easier to debug memory leaks. We don't expect any behavior to change as a result. A new feature to allow removal of connection pools for versions was ported from Zope 2.6. This feature is needed by Zope to avoid denial of service attacks that allow a client to create an arbitrary number of version pools. Fixed several critical ZEO bugs. - If several client transactions were blocked waiting for the storage and one of the blocked clients disconnected, the server would attempt to restart one of the other waiting clients. Since the disconnected client did not have the storage lock, this could lead to deadlock. It could also cause the assertion "self._client is None" to fail. - If a storage server fails or times out between the vote and the finish, the ZEO cache could get populated with objects that didn't make it to the storage server. - If a client loses its connection to the server near the end of a transaction, it is now guaranteed to get a ClientDisconnected error even if it reconnects before the transaction finishes. This is necessary because the server will always abort the transaction. In some cases, the client would never see an error for the aborted transaction. - In tpc_finish(), reordered the calls so that the server's tpc_finish() is called (and must succeed) before we update the ZEO client cache. - The storage name is now prepended to the sort key, to ensure a unique global sort order if storages are named uniquely. This can prevent deadlock in some unusual cases. Fixed several serious flaws in the implementation of the ZEO authentication protocol. - The smac layer would accept a message without a MAC even after the session key was established. - The client never initialized its session key, so it never checked incoming messages or created MACs for outgoing messags. - The smac layer used a single HMAC instance for sending and receiving messages. This approach could only work if client and server were guaranteed to process all messages in the same total order, which could only happen in simple scenarios like unit tests. Fixed a bug in ExtensionClass when comparing ExtensionClass instances. The code could raise RuntimeWarning under Python 2.3, and produce incorrect results on 64-bit platforms. Fixed bug in BDBStorage that could lead to DBRunRecoveryErrors when a transaction was aborted after performing operations like commit version or undo that create new references to existing pickles. Fixed a bug in Connection.py that caused it to fail with an AttributeError if close() was called after the database was closed. The test suite leaves fewer log files behind, although it still leaves a lot of junk. The test.py script puts each tests temp files in a separate directory, so it is easier to see which tests are causing problems. Unfortunately, it is still to tedious to figure out why the identified tests are leaving files behind. This release contains the latest and greatest version of the BDBStorage. This storage has still not seen testing in a production environment, but it represents the current best design and most recent code culled from various branches where development has occurred. The Tools directory contains a number of small improvements, a few new tools, and README.txt that catalogs the tools. Many of the tools are installed by setup.py; those scripts will now have a #! line set automatically on Unix. Fixed bugs in Tools/repozo.py, including a timing-dependent one that could cause the following invocation of repozo to do a full backup when an incremental backup would have sufficed. A pair of new scripts from Jim Fulton can be used to synthesize workloads and measure ZEO performance: see zodbload.py and zeoserverlog.py in the Tools directory. Note that these require Zope. Tools/checkbtrees.py was strengthened in two ways: - In addition to running the _check() method on each BTree B found, BTrees.check.check(B) is also run. The check() function was written after checkbtrees.py, and identifies kinds of damage B._check() cannot find. - Cycles in the object graph no longer lead to unbounded output. Note that preventing this requires remembering the oid of each persistent object found, which increases the memory needed by the script. What's new in ZODB3 3.2 beta 2 ============================== Release date: 16-Jun-2003 Fixed critical race conditions in ZEO's cache consistency code that could cause invalidations to be lost or stale data to be written to the cache. These bugs can lead to data loss or data corruption. These bugs are relatively unlikely to be provoked in sites with few conflicts, but the possibility of failure existed any time an object was loaded and stored concurrently. Fixed a bug in conflict resolution that failed to ghostify an object if it was involved in a conflict. (This code may be redundant, but it has been fixed regardless.) The ZEO server was fixed so that it does not perform any I/O until all of a transactions' invalidations are queued. If it performs I/O in the middle of sending invalidations, it would be possible to overlap a load from a client with the invalidation being sent to it. The ZEO cache now handles invalidations atomically. This is the same sort of bug that is described in the 3.1.2b1 section below, but it affects the ZEO cache. Fixed several serious bugs in fsrecover that caused it to fail catastrophically in certain cases because it thought it had found a checkpoint (status "c") record when it was in the middle of the file. Two new features snuck into this beta release. The ZODB.transact module provides a helper function that converts a regular function or method into a transactional one. The ZEO client cache now supports Adaptable Persistence (APE). The cache used to expect that all OIDs were eight bytes long. What's new in ZODB3 3.2 beta 1 ============================== Release date: 30-May-2003 ZODB ---- Invalidations are now processed atomically. Each transaction will see all the changes caused by an earlier transaction or none of them. Before this patch, it was possible for a transaction to see invalid data because it saw only a subset of the invalidations. This is the most likely cause of reported BTrees corruption, where keys were stored in the wrong bucket. When a BTree bucket splits, the bucket and the bucket's parent are both modified. If a transaction sees the invalidation for the bucket but not the parent, the BTree in memory will be internally inconsistent and keys can be put in the wrong bucket. The atomic invalidation fix prevents this problem. A number of minor reference count fixes in the object cache were fixed. That's the cPickleCache.c file. It was possible for a transaction that failed in tpc_finish() to lose the traceback that caused the failure. The transaction code was fixed to report the original error as well as any errors that occur while trying to recover from the original error. The "other" argument to copyTransactionsFrom() only needs to have an .iterator() method. For convenience, change FileStorage's and BDBFullStorage's iterator to have this method, which just returns self. Mount points are now visible from mounted objects. Fixed memory leak involving database connections and caches. When a connection or database was closed, the cache and database leaked, because of a circular reference involving the cache. Fixed the cache to explicitly clear out its contents when its connection is closed. The ZODB cache has fewer methods. It used to expose methods that could mutate the dictionary, which allowed users to violate internal invariants. ZConfig ------- It is now possible to configure ZODB databases and storages and ZEO servers using ZConfig. ZEO & zdaemon ------------- ZEO now supports authenticated client connections. The default authentication protocol uses a hash-based challenge-response protocol to prove identity and establish a session key for message authentication. The architecture is pluggable to allow third-parties to developer better authentication protocols. There is a new HOWTO for running a ZEO server. The draft in this release is incomplete, but provides more guidance than previous releases. See the file Doc/ZEO/howto.txt. The ZEO storage server's transaction timeout feature was refactored and made slightly more rebust. A new ZEO utility script, ZEO/mkzeoinst.py, was added. This creates a standard directory structure and writes a configuration file with mostly default values, and a bootstrap script that can be used to manage and monitor the server using zdctl.py (see below). Much work was done to improve zdaemon's zdctl.py and zdrun.py scripts. (In the alpha 1 release, zdrun.py was called zdaemon.py, but installing it in /bin caused much breakage due to the name conflict with the zdaemon package.) Together with the new mkzeoinst.py script, this makes controlling a ZEO server a breeze. A ZEO client will not read from its cache during cache verification. This fix was necessary to prevent the client from reading inconsistent data. The isReadOnly() method of a ZEO client was fixed to return the false when the client is connected to a read-only fallback server. The sync() method of ClientStorage and the pending() method of a zrpc connection now do both input and output. The short_repr() function used to generate log messages was fixed so that it does not blow up creating a repr of very long tuples. Storages -------- FileStorage has a new pack() implementation that fixes several reported problems that could lead to data loss. Two small bugs were fixed in DemoStorage. undoLog() did not handle its arguments correctly and pack() could accidentally delete objects created in versions. Fixed trivial bug in fsrecover that prevented it from working at all. FileStorage will use fsync() on Windows starting with Python 2.2.3. FileStorage's commit version was fixed. It used to stop after the first object, leaving all the other objects in the version. BTrees ------ Trying to store an object of a non-integer type into an IIBTree or OIBTree could leave the bucket in a variety of insane states. For example, trying b[obj] = "I'm a string, not an integer" where b is an OIBTree. This manifested as a refcount leak in the test suite, but could have been much worse (most likely in real life is that a seemingly arbitrary existing key would "go missing"). When deleting the first child of a BTree node with more than one child, a reference to the second child leaked. This could cause the entire bucket chain to leak (not be collected as garbage despite not being referenced anymore). Other minor BTree leak scenarios were also fixed. Tools ----- New tool zeoqueue.py for parsing ZEO log files, looking for blocked transactions. New tool repozo.py (originally by Anthony Baxter) for performing incremental backups of Data.fs files. The fsrecover.py script now does a better job of recovering from errors the occur in the middle of a transaction record. Fixed several bugs that caused partial or total failures in earlier versions. What's new in ZODB3 3.2 alpha 1 =============================== Release date: 17-Jan-2003 Most of the changes in this release are performance and stability improvements to ZEO. A major packaging change is that there won't be a separate ZEO release. The new ZConfig is a noteworthy addtion (see below). ZODB ---- An experimental new transaction API was added. The Connection class has a new method, setLocalTransaction(). ZODB applications can call this method to bind transactions to connections rather than threads. This is especially useful for GUI applications, which often have only one thread but multiple independent activities within that thread (generally one per window). Thanks to Christian Reis for championing this feature. Applications that take advantage of this feature should not use the get_transaction() function. Until now, ZODB itself sometimes assumed get_transaction() was the only way to get the transaction. Minor corrections have been added. The ZODB test suite, on the other hand, can continue to use get_transaction(), since it is free to assume that transactions are bound to threads. ZEO --- There is a new recommended script for starting a storage server. We recommend using ZEO/runzeo.py instead of ZEO/start.py. The start.py script is still available in this release, but it will no longer be maintained and will eventually be removed. There is a new zdaemon implementation. This version is a separate script that runs an arbitrary daemon. To run the ZEO server as a daemon, you would run "zdrun.py runzeo.py". There is also a simple shell, zdctl.py, that can be used to manage a daemon. Try "zdctl.py -p runzeo.py". There is a new version of the ZEO protocol in this release and a first stab at protocol negotiation. (It's a first stab because the protocol checking supporting in ZODB 3.1 was too primitive to support anything better.) A ZODB 3.2 ZEO client can talk to an old server, but a ZODB 3.2 server can't talk to an old client. It's safe to upgrade all the clients first and upgrade the server last. The ZEO client cache format changed, so you'll need to delete persistent caches before restarting clients. The ZEO cache verification protocol was revised to require many fewer messages in cases where a client or server restarts quickly. The performance of full cache verification has improved dramatically. Measurements from Jim were somewhere in 2x-5x. The implementation was fixed to use the very-fast getSerial() method on the storage instead of the comparatively slow load(). The ZEO server has an optional timeout feature that will abort a connection that does not commit within a certain amount of time. The timeout works by closing the socket the client is using, causing both client and server to abort the transaction and continue. This is a drastic step, but can be useful to prevent a hung client or other bug from blocking a server indefinitely. A bug was fixed in the ZEO protocol that allowed clients to read stale cache data while cache verification was being performed. The fixed version prevents the client from using the storage until after verification completes. The ZEO server has an experimental monitoring interface that reports usage statistics for the storage server including number of connected clients and number of transactions active and committed. It can be enabled by passing the -m flag to runsvr.py. The ZEO ClientStorage no longer supports the environment variables CLIENT_HOME, INSTANCE_HOME, or ZEO_CLIENT. The ZEO1 package is still included with this release, but there is no longer an option to install it. BTrees ------ The BTrees package now has a check module that inspects a BTree to check internal invariants. Bugs in older versions of the code code leave a BTree in an inconsistent state. Calling BTrees.check.check() on a BTree object should verify its consistency. (See the NEWS section for 3.1 beta 1 below to for the old BTrees bugs.) Fixed a rare conflict resolution problem in the BTrees that could cause an segfault when the conflict resolution resulted in any empty bucket. Installation ------------ The distutils setup now installs several Python scripts. The runzeo.py and zdrun.py scripts mentioned above and several fsXXX.py scripts from the Tools directory. The test.py script does not run all the ZEO tests by default, because the ZEO tests take a long time to run. Use --all to run all the tests. Otherwise a subset of the tests, mostly using MappingStorage, are run. Storages -------- There are two new storages based on Sleepycat's BerkeleyDB in the BDBStorage package. Barry will have to write more here, because I don't know how different they are from the old bsddb3Storage storages. See Doc/BDBStorage.txt for more information. It now takes less time to open an existing FileStorage. The FileStorage uses a BTree-based index that is faster to pickle and unpickle. It also saves the index periodically so that subsequent opens will go fast even if the storage was not closed cleanly. Misc ---- The new ZConfig package, which will be used by Zope and ZODB, is included. ZConfig provides a configuration syntax, similar to Apache's syntax. The package can be used to configure the ZEO server and ZODB databases. See the module ZODB.config for functions to open the database from configuration. See ZConfig/doc for more info. The zLOG package now uses the logging package by Vinay Sajip, which will be included in Python 2.3. The Sync extension was removed from ExtensionClass, because it was not used by ZODB. What's new in ZODB3 3.1.4? ========================== Release date: 11-Sep-2003 A new feature to allow removal of connection pools for versions was ported from Zope 2.6. This feature is needed by Zope to avoid denial of service attacks that allow a client to create an arbitrary number of version pools. A pair of new scripts from Jim Fulton can be used to synthesize workloads and measure ZEO performance: see zodbload.py and zeoserverlog.py in the Tools directory. Note that these require Zope. Tools/checkbtrees.py was strengthened in two ways: - In addition to running the _check() method on each BTree B found, BTrees.check.check(B) is also run. The check() function was written after checkbtrees.py, and identifies kinds of damage B._check() cannot find. - Cycles in the object graph no longer lead to unbounded output. Note that preventing this requires remembering the oid of each persistent object found, which increases the memory needed by the script. What's new in ZODB3 3.1.3? ========================== Release date: 18-Aug-2003 Fixed several critical ZEO bugs. - If a storage server fails or times out between the vote and the finish, the ZEO cache could get populated with objects that didn't make it to the storage server. - If a client loses its connection to the server near the end of a transaction, it is now guaranteed to get a ClientDisconnected error even if it reconnects before the transaction finishes. This is necessary because the server will always abort the transaction. In some cases, the client would never see an error for the aborted transaction. - In tpc_finish(), reordered the calls so that the server's tpc_finish() is called (and must succeed) before we update the ZEO client cache. - The storage name is now prepended to the sort key, to ensure a unique global sort order if storages are named uniquely. This can prevent deadlock in some unusual cases. A variety of fixes and improvements to Berkeley storage (aka BDBStorage) were back-ported from ZODB 4. This release now contains the most current version of the Berkeley storage code. Many tests have been back-ported, but not all. Modified the Windows tests to wait longer at the end of ZEO tests for the server to shut down. Before Python 2.3, there is no waitpid() on Windows, and, thus, no way to know if the server has shut down. The change makes the Windows ZEO tests much less likely to fail or hang, at the cost of increasing the time needed to run the tests. Fixed a bug in ExtensionClass when comparing ExtensionClass instances. The code could raise RuntimeWarning under Python 2.3, and produce incorrect results on 64-bit platforms. Fixed bugs in Tools/repozo.py, including a timing-dependent one that could cause the following invocation of repozo to do a full backup when an incremental backup would have sufficed. Added Tools/README.txt that explains what each of the scripts in the Tools directory does. There were many small changes and improvements to the test suite. What's new in ZODB3 3.1.2 final? ================================ Fixed bug in FileStorage pack that caused it to fail if it encountered an old undo record (status "u"). Fixed several bugs in FileStorage pack that could cause OverflowErrors for storages > 2 GB. Fixed memory leak in TimeStamp.laterThan() that only occurred when it had to create a new TimeStamp. Fixed two BTree bugs that were fixed on the head a while ago: - bug in fsBTree that would cause byValue searches to end early. (fsBTrees are never used this way, but it was still a bug.) - bug that lead to segfault if BTree was mutated via deletion while it was being iterated over. What's new in ZODB3 3.1.2 beta 2? ================================= Fixed critical race conditions in ZEO's cache consistency code that could cause invalidations to be lost or stale data to be written to the cache. These bugs can lead to data loss or data corruption. These bugs are relatively unlikely to be provoked in sites with few conflicts, but the possibility of failure existed any time an object was loaded and stored concurrently. Fixed a bug in conflict resolution that failed to ghostify an object if it was involved in a conflict. (This code may be redundant, but it has been fixed regardless.) The ZEO server was fixed so that it does not perform any I/O until all of a transactions' invalidations are queued. If it performs I/O in the middle of sending invalidations, it would be possible to overlap a load from a client with the invalidation being sent to it. The ZEO cache now handles invalidations atomically. This is the same sort of bug that is described in the 3.1.2b1 section below, but it affects the ZEO cache. Fixed several serious bugs in fsrecover that caused it to fail catastrophically in certain cases because it thought it had found a checkpoint (status "c") record when it was in the middle of the file. What's new in ZODB3 3.1.2 beta 1? ================================= ZODB ---- Invalidations are now processed atomically. Each transaction will see all the changes caused by an earlier transaction or none of them. Before this patch, it was possible for a transaction to see invalid data because it saw only a subset of the invalidations. This is the most likely cause of reported BTrees corruption, where keys were stored in the wrong bucket. When a BTree bucket splits, the bucket and the bucket's parent are both modified. If a transaction sees the invalidation for the bucket but not the parent, the BTree in memory will be internally inconsistent and keys can be put in the wrong bucket. The atomic invalidation fix prevents this problem. A number of minor reference count fixes in the object cache were fixed. That's the cPickleCache.c file. It was possible for a transaction that failed in tpc_finish() to lose the traceback that caused the failure. The transaction code was fixed to report the original error as well as any errors that occur while trying to recover from the original error. ZEO --- A ZEO client will not read from its cache during cache verification. This fix was necessary to prevent the client from reading inconsistent data. The isReadOnly() method of a ZEO client was fixed to return the false when the client is connected to a read-only fallback server. The sync() method of ClientStorage and the pending() method of a zrpc connection now do both input and output. The short_repr() function used to generate log messages was fixed so that it does not blow up creating a repr of very long tuples. Storages -------- FileStorage has a new pack() implementation that fixes several reported problems that could lead to data loss. Two small bugs were fixed in DemoStorage. undoLog() did not handle its arguments correctly and pack() could accidentally delete objects created in versions. Fixed trivial bug in fsrecover that prevented it from working at all. FileStorage will use fsync() on Windows starting with Python 2.2.3. FileStorage's commit version was fixed. It used to stop after the first object, leaving all the other objects in the version. BTrees ------ Trying to store an object of a non-integer type into an IIBTree or OIBTree could leave the bucket in a variety of insane states. For example, trying b[obj] = "I'm a string, not an integer" where b is an OIBTree. This manifested as a refcount leak in the test suite, but could have been much worse (most likely in real life is that a seemingly arbitrary existing key would "go missing"). When deleting the first child of a BTree node with more than one child, a reference to the second child leaked. This could cause the entire bucket chain to leak (not be collected as garbage despite not being referenced anymore). Other minor BTree leak scenarios were also fixed. Other ----- Comparing a Missing.Value object to a C type that provide its own comparison operation could lead to a segfault when the Missing.Value was on the right-hand side of the comparison operator. The Missing class was fixed so that its coercion and comparison operations are safe. Tools ----- Four tools are now installed by setup.py: fsdump.py, fstest.py, repozo.py, and zeopack.py. What's new in ZODB3 3.1.1 final? ================================ Release date: 11-Feb-2003 Tools ----- Updated repozo.py tool What's new in ZODB3 3.1.1 beta 2? ================================= Release date: 03-Feb-2003 The Transaction "hosed" feature is disabled in this release. If a transaction fails during the tpc_finish() it is not possible, in general, to know whether the storage is in a consistent state. For example, a ZEO server may commit the data and then fail before sending confirmation of the commit to the client. If multiple storages are involved in a transaction, the problem is exacerbated: One storage may commit the data while another fails to commit. In previous versions of ZODB, the database would set a global "hosed" flag that prevented any other transaction from committing until an administrator could check the status of the various failed storages and ensure that the database is in a consistent state. This approach favors data consistency over availability. The new approach is to log a panic but continue. In practice, availability seems to be more important than consistency. The failure mode is exceedingly rare in either case. The BTrees-based fsIndex for FileStorage is enabled. This version of the index is faster to load and store via pickle and uses less memory to store keys. We had intended to enable this feature in an earlier release, but failed to actually do it; thus, it's getting enabled as a bug fix now. Two rare bugs were fixed in BTrees conflict resolution. The most probable symptom of the bug would have been a segfault. The bugs were found via synthetic stress tests rather than bug reports. A value-based consistency checker for BTrees was added. See the module BTrees.check for the checker and other utilities for working with BTrees. A new script called repozo.py was added. This script, originally written by Anthony Baxter, provides an incremental backup scheme for FileStorage based storages. zeopack.py has been fixed to use a read-only connection. Various small autopack-related race conditions have been fixed in the Berkeley storage implementations. There have been some table changes to the Berkeley storages so any storage you created in 3.1.1b1 may not work. Part of these changes was to add a storage version number to the schema so these types of incompatible changes can be avoided in the future. Removed the chance of bogus warnings in the FileStorage iterator. ZEO --- The ZEO version number was bumped to 2.0.2 on account of the following minor feature additions. The performance of full cache verification has improved dramatically. Measurements from Jim were somewhere in 2x-5x. The implementation was fixed to use the very-fast getSerial() method on the storage instead of the comparatively slow load(). The ZEO server has an optional timeout feature that will abort a connection that does not commit within a certain amount of time. The timeout works by closing the socket the client is using, causing both client and server to abort the transaction and continue. This is a drastic step, but can be useful to prevent a hung client or other bug from blocking a server indefinitely. If a client was disconnected during a transaction, the tpc_abort() call did not properly reset the internal state about the transaction. The bug caused the next transaction to fail in its tpc_finish(). Also, any ClientDisconnected exceptions raised during tpc_abort() are ignored. ZEO logging has been improved by adding more logging for important events, and changing the logging level for existing messages to a more appropriate level (usually lower). What's new in ZODB3 3.1.1 beta 1? ================================= Release date: 10-Dev-2002 It was possible for earlier versions of ZODB to deadlock when using multiple storages. If multiple transactions committed concurrently and both transactions involved two or more shared storages, deadlock was possible. This problem has been fixed by introducing a sortKey() method to the transaction and storage APIs that is used to define an ordering on transaction participants. This solution will prevent deadlocks provided that all transaction participants that use locks define a valid sortKey() method. A warning is raised if a participant does not define sortKey(). For backwards compatibility, BaseStorage provides a sortKey() that uses __name__. Added code to ThreadedAsync/LoopCallback.py to work around a bug in asyncore.py: a handled signal can cause unwanted reads to happen. A bug in FileStorage related to object uncreation was fixed. If an a transaction that created an object was undone, FileStorage could write a bogus data record header that could lead to strange errors if the object was loaded. An attempt to load an uncreated object now raises KeyError, as expected. The restore() implementation in FileStorage wrote incorrect backpointers for a few corner cases involving versions and undo. It also failed if the backpointer pointed to a record that was before the pack time. These specific bugs have been fixed and new test cases were added to cover them. A bug was fixed in conflict resolution that raised a NameError when a class involved in a conflict could not be loaded. The bug did not affect correctness, but prevent ZODB from caching the fact that the class was unloadable. A related bug prevented spurious AttributeErrors when a class could not be loaded. It was also fixed. The script Tools/zeopack.py was fixed to work with ZEO 2. It was untested and had two silly bugs. Some C extensions included standard header files before including Python.h, which is not allowed. They now include Python.h first, which eliminates compiler warnings in certain configurations. The BerkeleyDB based storages have been merged from the trunk, providing a much more robust version of the storages. They are not backwards compatible with the old storages, but the decision was made to update them in this micro release because the old storages did not work for all practical purposes. For details, see Doc/BDBStorage.txt. What's new in ZODB3 3.1 final? =============================== Release date: 28-Oct-2002 If an error occurs during conflict resolution, the store will silently catch the error, log it, and continue as if the conflict was unresolvable. ZODB used to behave this way, and the change to catch only ConflictError was causing problems in deployed systems. There are a lot of legitimate errors that should be caught, but it's too close to the final release to make the substantial changes needed to correct this. What's new in ZODB3 3.1 beta 3? =============================== Release date: 21-Oct-2002 A small extension was made to the iterator protocol. The Record objects, which are returned by the per-transaction iterators, contain a new `data_txn` attribute. It is None, unless the data contained in the record is a logical copy of an earlier transaction's data. For example, when transactional undo modifies an object, it creates a logical copy of the earlier transaction's data. Note that this provide a stronger statement about consistency than whether the data in two records is the same; it's possible for two different updates to an object to coincidentally have the same data. The restore() method was extended to take the data_txn attribute mentioned above as an argument. FileStorage uses the new argument to write a backpointer if possible. A few bugs were fixed. The setattr slot of the cPersistence C API was being initialized to NULL. The proper initialization was restored, preventing crashes in some applications with C extensions that used persistence. The return value of TimeStamp's __cmp__ method was clipped to return only 1, 0, -1. The restore() method was fixed to write a valid backpointer if the update being restored is in a version. Several bugs and improvements were made to zdaemon, which can be used to run the ZEO server. The parent now forwards signals to the child as intended. Pidfile handling was improved and the trailing newline was omitted. What's new in ZODB3 3.1 beta 2? =============================== Release date: 4-Oct-2002 A few bugs have been fixed, some that were found with the help of Neal Norwitz's PyChecker. The zeoup.py tool has been fixed to allow connecting to a read-only storage, when the --nowrite option is given. Casey Duncan fixed a few bugs in the recent changes to undoLog(). The fstest.py script no longer checks that each object modified in a transaction has a serial number that matches the transaction id. This invariant is no longer maintained; several new features in the 3.1 release depend on it. The ZopeUndo package was added. If ZODB3 is being used to run a ZEO server that will be used with Zope, it is usually best if the server and the Zope client don't share any software. The Zope undo framework, however, requires that a Prefix object be passed between client and server. To support this use, ZopeUndo was created to hold the Prefix object. Many bugs were fixed in ZEO, and a couple of features added. See `ZEO-NEWS.txt` for details. The ZODB guide included in the Doc directory has been updated. It is still incomplete, but most of the references to old ZODB packages have been removed. There is a new section that briefly explains how to use BTrees. The zeoup.py tool connects using a read-only connection when --nowrite is specifified. This feature is useful for checking on read-only ZEO servers. What's new in ZODB3 3.1 beta 1? =============================== Release date: 12-Sep-2002 We've changed the name and version number of the project, but it's still the same old ZODB. There have been a lot of changes since the last release. New ZODB cache -------------- Toby Dickenson implemented a new Connection cache for ZODB. The cache is responsible for pointer swizzling (translating between oids and Python objects) and for keeping recently used objects in memory. The new cache is a big improvement over the old cache. It strictly honors its size limit, where size is specified in number of objects, and it evicts objects in least recently used (LRU) order. Users should take care when setting the cache size, which has a default value of 400 objects. The old version of the cache often held many more objects than its specified size. An application may not perform as well with a small cache size, because the cache no longer exceeds the limit. Storages -------- The index used by FileStorage was reimplemented using a custom BTrees object. The index maps oids to file offsets, and is kept in memory at all times. The new index uses about 1/4 the memory of the old, dictionary-based index. See the module ZODB.fsIndex for details. A security flaw was corrected in transactionalUndo(). The transaction ids returned by undoLog() and used for transactionalUndo() contained a file offset. An attacker could construct a pickle with a bogus transaction record in its binary data, deduce the position of the pickle in the file from the undo log, then submit an undo with a bogus file position that caused the pickle to get written as a regular data record. The implementation was fixed so that file offsets are not included in the transaction ids. Several storages now have an explicit read-only mode. For example, passing the keyword argument read_only=1 to FileStorage will make it read-only. If a write operation is performed on a read-only storage, a ReadOnlyError will be raised. The storage API was extended with new methods that support the Zope Replication Service (ZRS), a proprietary Zope Corp product. We expect these methods to be generally useful. The methods are: - restore(oid, serialno, data, version, transaction) Perform a store without doing consistency checks. A client can use this method to provide a new current revision of an object. The ``serialno`` argument is the new serialno to use for the object, not the serialno of the previous revision. - lastTransaction() Returns the transaction id of the last committed transaction. - lastSerial(oid) Return the current serialno for ``oid`` or None. - iterator(start=None, stop=None) The iterator method isn't new, but the optional ``start`` and ``stop`` arguments are. These arguments can be used to specify the range of the iterator -- an inclusive range [start, stop]. FileStorage is now more cautious about creating a new file when it believes a file does not exist. This change is a workaround for bug in Python versions upto and including 2.1.3. If the interpreter was builtin without large file support but the platform had it, os.path.exists() would return false for large files. The fix is to try to open the file first, and decide whether to create a new file based on errno. The undoLog() and undoInfo() methods of FileStorage can run concurrently with other methods. The internal storage lock is released periodically to give other threads a chance to run. This should increase responsiveness of ZEO clients when used with ZEO 2. New serial numbers are assigned consistently for abortVersion() and commitVersion(). When a version is committed, the non-version data gets a new serial number. When a version is aborted, the serial number for non-version data does not change. This means that the abortVersion() transaction record has the unique property that its transaction id is not the serial number of the data records. Berkeley Storages ----------------- Berkeley storage constructors now take an optional `config` argument, which is an instance whose attributes can be used to configure such BerkeleyDB policies as an automatic checkpointing interval, lock table sizing, and the log directory. See bsddb3Storage/BerkeleyBase.py for details. A getSize() method has been added to all Berkeley storages. Berkeley storages open their environments with the DB_THREAD flag. Some performance optimizations have been implemented in Full storage, including the addition of a helper C extension when used with Python 2.2. More performance improvements will be added for the ZODB 3.1 final release. A new experimental Autopack storage was added which keeps only a certain amount of old revision information. The concepts in this storage will be folded into Full and Autopack will likely go away in ZODB 3.1 final. ZODB 3.1 final will also have much improved Minimal and Full storages, which eliminate Berkeley lock exhaustion problems, reduce memory use, and improve performance. It is recommended that you use BerkeleyDB 4.0.14 and PyBSDDB 3.4.0 with the Berkeley storages. See bsddb3Storage/README.txt for details. BTrees ------ BTrees no longer ignore exceptions raised when two keys are compared. Tim Peters fixed several endcase bugs in the BTrees code. Most importantly, after a mix of inserts and deletes in a BTree or TreeSet, it was possible (but unlikely) for the internal state of the object to become inconsistent. Symptoms then varied; most often this manifested as a mysterious failure to find a key that you knew was present, or that tree.keys() would yield an object that disgreed with the tree about how many keys there were. If you suspect such a problem, BTrees and TreeSets now support a ._check() method, which does a thorough job of examining the internal tree pointers for consistency. It raises AssertionError if it finds any problems, else returns None. If ._check() raises an exception, the object is damaged, and rebuilding the object is the best solution. All known ways for a BTree or TreeSet object to become internally inconsistent have been repaired. Other fixes include: - Many fixes for range search endcases, including the "range search bug:" If the smallest key S in a bucket in a BTree was deleted, doing a range search on the BTree with S on the high end could claim that the range was empty even when it wasn't. - Zope Collector #419: repaired off-by-1 errors and IndexErrors when slicing BTree-based data structures. For example, an_IIBTree.items()[0:0] had length 1 (should be empty) if the tree wasn't empty. - The BTree module functions weightedIntersection() and weightedUnion() now treat negative weights as documented. It's hard to explain what their effects were before this fix, as the sign bits were getting confused with an internal distinction between whether the result should be a set or a mapping. ZEO ---- For news about ZEO2, see the file ZEO-NEWS.txt. This version of ZODB ships with two different versions of ZEO. It includes ZEO 2.0 beta 1, the recommended new version. (ZEO 2 will reach final release before ZODB3.) The ZEO 2.0 protocol is not compatible with ZEO 1.0, so we have also included ZEO 1.0 to support people already using ZEO 1.0. Other features -------------- When a ConflictError is raised, the exception object now has a sensible structure, thanks to a patch from Greg Ward. The exception now uses the following standard attributes: oid, class_name, message, serials. See the ZODB.POSException.ConflictError doc string for details. It is now easier to customize the registration of persistent objects with a transaction. The low-level persistence mechanism in cPersistence.c registers with the object's jar instead of with the current transaction. The jar (Connection) then registers with the transaction. This redirection would allow specialized Connections to change the default policy on how the transaction manager is selected without hacking the Transaction module. Empty transactions can be committed without interacting with the storage. It is possible for registration to occur unintentionally and for a persistent object to compensate by making itself as unchanged. When this happens, it's possible to commit a transaction with no modified objects. The change allows such transactions to finish even on a read-only storage. Two new tools were added to the Tools directory. The ``analyze.py`` script, based on a tool by Matt Kromer, prints a summary of space usage in a FileStorage Data.fs. The ``checkbtrees.py`` script scans a FileStorage Data.fs. When it finds a BTrees object, it loads the object and calls the ``_check`` method. It prints warning messages for any corrupt BTrees objects found. Documentation ------------- The user's guide included with this release is still woefully out of date. Other bugs fixed ---------------- If an exception occurs inside an _p_deactivate() method, a traceback is printed on stderr. Previous versions of ZODB silently cleared the exception. ExtensionClass and ZODB now work correctly with a Python debug build. All C code has been fixed to use a consistent set of functions from the Python memory API. This allows ZODB to be used in conjunction with pymalloc, the default allocator in Python 2.3. zdaemon, which can be used to run a ZEO server, more clearly reports the exit status of its child processes. The ZEO server will reinitialize zLOG when it receives a SIGHUP. This allows log file rotation without restarting the server. What's new in StandaloneZODB 1.0 final? ======================================= Release date: 08-Feb-2002 All copyright notices have been updated to reflect the fact that the ZPL 2.0 covers this release. Added a cleanroom PersistentList.py implementation, which multiply inherits from UserDict and Persistent. Some improvements in setup.py and test.py for sites that don't have the Berkeley libraries installed. A new program, zeoup.py was added which simply verifies that a ZEO server is reachable. Also, a new program zeopack.py was added which connects to a ZEO server and packs it. What's new in StandaloneZODB 1.0 c1? ==================================== Release Date: 25-Jan-2002 This was the first public release of the StandaloneZODB from Zope Corporation. Everything's new! :) zope2.13-2.13.21/source/ZODB3/COPYING0000644000175000017500000000013312214017464015311 0ustar arnauarnauSee: - the copyright notice in: COPYRIGHT.txt - The Zope Public License in LICENSE.txt zope2.13-2.13.21/source/ZODB3/pip-egg-info/0000755000175000017500000000000012214017465016543 5ustar arnauarnauzope2.13-2.13.21/source/ZODB3/pip-egg-info/ZODB3.egg-info/0000755000175000017500000000000012214017465021056 5ustar arnauarnauzope2.13-2.13.21/source/ZODB3/pip-egg-info/ZODB3.egg-info/PKG-INFO0000644000175000017500000006077712214017465022174 0ustar arnauarnauMetadata-Version: 1.1 Name: ZODB3 Version: 3.10.5 Summary: Zope Object Database: object database and persistence Home-page: UNKNOWN Author: Zope Foundation and Contributors Author-email: zodb-dev@zope.org License: ZPL 2.1 Description: The Zope Object Database provides an object-oriented database for Python that provides a high-degree of transparency. Applications can take advantage of object database features with few, if any, changes to application logic. ZODB includes features such as a plugable storage interface, rich transaction support, and undo. .. contents:: ==== ZODB ==== Introduction ============ The ZODB package provides a set of tools for using the Zope Object Database (ZODB). The components you get with the ZODB release are as follows: - Core ZODB, including the persistence machinery - Standard storages such as FileStorage - The persistent BTrees modules - ZEO, for scalability needs - documentation (needs a lot more work) Our primary development platforms are Linux, Mac OS X, and Windows XP. The test suite should pass without error on all of these platforms, although it can take a long time on Windows -- longer if you use ZoneAlarm. Many particularly slow tests are skipped unless you pass --all as an argument to test.py. Compatibility ============= ZODB 3.10 requires Python 2.5 or later. Note -- When using ZEO and upgrading from Python 2.4, you need to upgrade clients and servers at the same time, or upgrade clients first and then servers. Clients running Python 2.5 or 2.6 will work with servers running Python 2.4. Clients running Python 2.4 won't work properly with servers running Python 2.5 or later due to changes in the way Python implements exceptions. ZODB ZEO clients from ZODB 3.2 on can talk to ZODB 3.10 servers. ZODB ZEO 3.10 Clients can talk to ZODB 3.8, 3.9, and 3.10 ZEO servers. Note -- ZEO 3.10 servers don't support undo for older clients. Prerequisites ============= You must have Python installed. If you're using a system Python install, make sure development support is installed too. You also need the transaction, zc.lockfile, ZConfig, zdaemon, zope.event, zope.interface, zope.proxy and zope.testing packages. If you don't have them and you can connect to the Python Package Index, then these will be installed for you if you don't have them. Installation ============ ZODB is released as a distutils package. The easiest ways to build and install it are to use `easy_install `_, or `zc.buildout `_. To install by hand, first install the dependencies, ZConfig, zdaemon, zope.interface, zope.proxy and zope.testing. These can be found in the `Python Package Index `_. To run the tests, use the test setup command:: python setup.py test It will download dependencies if needed. If this happens, ou may get an import error when the test command gets to looking for tests. Try running the test command a second time and you should see the tests run. :: python setup.py test To install, use the install command:: python setup.py install Testing for Developers ====================== The ZODB checkouts are `buildouts `_. When working from a ZODB checkout, first run the bootstrap.py script to initialize the buildout: % python bootstrap.py and then use the buildout script to build ZODB and gather the dependencies: % bin/buildout This creates a test script: % bin/test -v This command will run all the tests, printing a single dot for each test. When it finishes, it will print a test summary. The exact number of tests can vary depending on platform and available third-party libraries.:: Ran 1182 tests in 241.269s OK The test script has many more options. Use the ``-h`` or ``--help`` options to see a file list of options. The default test suite omits several tests that depend on third-party software or that take a long time to run. To run all the available tests use the ``--all`` option. Running all the tests takes much longer.:: Ran 1561 tests in 1461.557s OK Maintenance scripts ------------------- Several scripts are provided with the ZODB and can help for analyzing, debugging, checking for consistency, summarizing content, reporting space used by objects, doing backups, artificial load testing, etc. Look at the ZODB/script directory for more informations. History ======= The historical version numbering schemes for ZODB and ZEO are complicated. Starting with ZODB 3.4, the ZODB and ZEO version numbers are the same. In the ZODB 3.1 through 3.3 lines, the ZEO version number was "one smaller" than the ZODB version number; e.g., ZODB 3.2.7 included ZEO 2.2.7. ZODB and ZEO were distinct releases prior to ZODB 3.1, and had independent version numbers. Historically, ZODB was distributed as a part of the Zope application server. Jim Fulton's paper at the Python conference in 2000 described a version of ZODB he called ZODB 3, based on an earlier persistent object system called BoboPOS. The earliest versions of ZODB 3 were released with Zope 2.0. Andrew Kuchling extracted ZODB from Zope 2.4.1 and packaged it for use by standalone Python programs. He called this version "StandaloneZODB". Andrew's guide to using ZODB is included in the Doc directory. This version of ZODB was hosted at http://sf.net/projects/zodb. It supported Python 1.5.2, and might still be of interest to users of this very old Python version. Zope Corporation released a version of ZODB called "StandaloneZODB 1.0" in Feb. 2002. This release was based on Andrew's packaging, but built from the same CVS repository as Zope. It is roughly equivalent to the ZODB in Zope 2.5. Why not call the current release StandaloneZODB? The name StandaloneZODB is a bit of a mouthful. The standalone part of the name suggests that the Zope version is the real version and that this is an afterthought, which isn't the case. So we're calling this release "ZODB". We also worked on a ZODB4 package for a while and made a couple of alpha releases. We've now abandoned that effort, because we didn't have the resources to pursue ot while also maintaining ZODB(3).

Local Variables: mode: indented-text indent-tabs-mode: nil sentence-end-double-space: t fill-column: 70 End: ================ Change History ================ 3.10.5 (2011-11-19) =================== Bugs Fixed ---------- - Conflict resolution failed when state included cross-database persistent references with classes that couldn't be imported. 3.10.4 (2011-11-17) =================== Bugs Fixed ---------- - Conflict resolution failed when state included persistent references with classes that couldn't be imported. 3.10.3 (2011-04-12) =================== Bugs Fixed ---------- - "activity monitor not updated for subconnections when connection returned to pool" https://bugs.launchpad.net/zodb/+bug/737198 - "Blob temp file get's removed before it should", https://bugs.launchpad.net/zodb/+bug/595378 A way this to happen is that a transaction is aborted after the commit process has started. I don't know how this would happen in the wild. In 3.10.3, the ZEO tpc_abort call to the server is changed to be synchronous, which should address this case. Maybe there's another case. Performance enhancements ------------------------ - Improved ZEO client cache implementation to make it less likely to evict objects that are being used. - Small (possibly negligable) reduction in CPU in ZEO storage servers to service object loads and in networking code. 3.10.2 (2011-02-12) =================== Bugs Fixed ---------- - 3.10 introduced an optimization to try to address BTree conflict errors arrising for basing BTree keys on object ids. The optimization caused object ids allocated in aborted transactions to be reused. Unfortunately, this optimzation led to some rather severe failures in some applications. The symptom is a conflict error in which one of the serials mentioned is zero. This optimization has been removed. See (for example): https://bugs.launchpad.net/zodb/+bug/665452 - ZEO server transaction timeouts weren't logged as critical. https://bugs.launchpad.net/zodb/+bug/670986 3.10.1 (2010-10-27) =================== Bugs Fixed ---------- - When a transaction rolled back a savepoint after adding objects and subsequently added more objects and committed, an error could be raised "ValueError: A different object already has the same oid" causing the transaction to fail. Worse, this could leave a database in a state where subsequent transactions in the same process would fail. https://bugs.launchpad.net/zodb/+bug/665452 - Unix domain sockets didn't work for ZEO (since the addition of IPv6 support). https://bugs.launchpad.net/zodb/+bug/663259 - Removed a missfeature that can cause performance problems when using an external garbage collector with ZEO. When objects were deleted from a storage, invalidations were sent to clients. This makes no sense. It's wildly unlikely that the other connections/clients have copies of the garbage. In normal storage garbage collection, we don't send invalidations. There's no reason to send them when an external garbage collector is used. - ZEO client cache simulation misshandled invalidations causing incorrect statistics and errors. 3.10.0 (2010-10-08) =================== New Features ------------ - There are a number of performance enhancements for ZEO storage servers. - FileStorage indexes use a new format. They are saved and loaded much faster and take less space. Old indexes can still be read, but new indexes won't be readable by older versions of ZODB. - The API for undoing multiple transactions has changed. To undo multiple transactions in a single transaction, pass a list of transaction identifiers to a database's undoMultiple method. Calling a database's undo method multiple times in the same transaction now raises an exception. - The ZEO protocol for undo has changed. The only user-visible consequence of this is that when ZODB 3.10 ZEO servers won't support undo for older clients. - The storage API (IStorage) has been tightened. Now, storages should raise a StorageTransactionError when invalid transactions are passed to tpc_begin, tpc_vote, or tpc_finish. - ZEO clients (``ClientStorage`` instances) now work in forked processes, including those created via ``multiprocessing.Process`` instances. - Broken objects now provide the IBroken interface. - As a convenience, you can now pass an integer port as an address to the ZEO ClientStorage constructor. - As a convenience, there's a new ``client`` function in the ZEO package for constructing a ClientStorage instance. It takes the same arguments as the ClientStorage constructor. - DemoStorages now accept constructor athuments, close_base_on_close and close_changes_on_close, to control whether underlying storages are closed when the DemoStorage is closed. https://bugs.launchpad.net/zodb/+bug/118512 - Removed the dependency on zope.proxy. - Removed support for the _p_independent mini framework, which was made moot by the introduction of multi-version concurrency control several years ago. - Added support for the transaction retry convenience (transaction-manager attempts method) introduced in the ``transaction`` 1.1.0 release. - Enhanced the database opening conveniences: - You can now pass storage keyword arguments to ZODB.DB and ZODB.connection. - You can now pass None (rather than a storage or file name) to get a database with a mapping storage. - Databases now warn when committing very large records (> 16MB). This is to try to warn people of likely design mistakes. There is a new option (large_record_size/large-record-size) to control the record size at which the warning is issued. - Added support for wrapper storages that transform pickle data. Applications for this include compression and encryption. An example wrapper storage implementation, ZODB.tests.hexstorage, was included for testing. It is important that storage implementations not assume that storages contain pickles. Renamed IStorageDB to IStorageWrapper and expanded it to provide methods for transforming and untransforming data records. Storages implementations should use these methods to get pickle data from stored records. - Deprecated ZODB.interfaces.StorageStopIteration. Storage iterator implementations should just raise StopIteration, which means they can now be implemented as generators. - The filestorage packer configuration option noe accepts values of the form ``modname:expression``, allowing the use of packer factories with options. - Added a new API that allows applications to make sure that current data are read. For example, with:: self._p_jar.readCurrent(ob) A conflict error will be raised if the version of ob read by the transaction isn't current when the transaction is committed. Normally, ZODB only assures that objects read are consistent, but not necessarily up to date. Checking whether an object is up to date is important when information read from one object is used to update another. BTrees are an important case of reading one object to update another. Internal nodes are read to decide which leave notes are updated when a BTree is updated. BTrees now use this new API to make sure that internal nodes are up to date on updates. - When transactions are aborted, new object ids allocated during the transaction are saved and used in subsequent transactions. This can help in situations where object ids are used as BTree keys and the sequential allocation of object ids leads to conflict errors. - ZEO servers now support a server_status method for for getting information on the number of clients, lock requests and general statistics. - ZEO clients now support a client_label constructor argument and client-label configuration-file option to specify a label for a client in server logs. This makes it easier to identify specific clients corresponding to server log entries, especially when there are multiple clients originating from the same machine. - Improved ZEO server commit lock logging. Now, locking activity is logged at the debug level until the number of waiting lock requests gets above 3. Log at the critical level when the number of waiting lock requests gets above 9. - The file-storage backup script, repozo, will now create a backup index file if an output file name is given via the --output/-o option. - Added a '--kill-old-on-full' argument to the repozo backup options: if passed, remove any older full or incremental backup files from the repository after doing a full backup. (https://bugs.launchpad.net/zope2/+bug/143158) - The mkzeoinst script has been moved to a separate project: http://pypi.python.org/pypi/zope.mkzeoinstance and is no-longer included with ZODB. - Removed untested unsupported dbmstorage fossile. - ZEO servers no longer log their pids in every log message. It's just not interesting. :) Bugs fixed ---------- - When a pool timeout was specified for a database and old connections were removed due to timing out, an error occured due to a bug in the connection cleanup logic. - When multi-database connections were no longer used and cleaned up, their subconnections weren't cleaned up properly. - ZEO didn't work with IPv6 addrsses. Added IPv6 support contributed by Martin v. |Lowis|. - A file storage bug could cause ZEO clients to have incorrect information about current object revisions after reconnecting to a database server. - Updated the 'repozo --kill-old-on-full' option to remove any '.index' files corresponding to backups being removed. - ZEO extension methods failed when a client reconnected to a storage. (https://bugs.launchpad.net/zodb/+bug/143344) - Clarified the return Value for lastTransaction in the case when there aren't any transactions. Now a string of 8 nulls (aka "z64") is specified. - Setting _p_changed on a blob wo actually writing anything caused an error. (https://bugs.launchpad.net/zodb/+bug/440234) - The verbose mode of the fstest was broken. (https://bugs.launchpad.net/zodb/+bug/475996) - Object ids created in a savepoint that is rolled back wren't being reused. (https://bugs.launchpad.net/zodb/+bug/588389) - Database connections didn't invalidate cache entries when conflict errors were raised in response to checkCurrentSerialInTransaction errors. Normally, this shouldn't be a problem, since there should be pending invalidations for these oids which will cause the object to be invalidated. There have been issues with ZEO persistent cache management that have caused out of date data to remain in the cache. (It's possible that the last of these were addressed in the 3.10.0b5.) Invalidating read data when there is a conflict error provides some extra insurance. - The interface, ZODB.interfaces.IStorage was incorrect. The store method should never return a sequence of oid and serial pairs. - When a demo storage push method was used to create a new demo storage and the new storage was closed, the original was (incorrectly) closed. - There were numerous bugs in the ZEO cache tracing and analysis code. Cache simulation, while not perfect, seems to be much more accurate now than it was before. The ZEO cache trace statistics and simulation scripts have been given more descriptive names and moved to the ZEO scripts package. - BTree sets and tree sets didn't correctly check values passed to update or to constructors, causing Python to exit under certain circumstances. - Fixed bug in copying a BTrees.Length instance. (https://bugs.launchpad.net/zodb/+bug/516653) - Fixed a serious bug that caused cache failures when run with Python optimization turned on. https://bugs.launchpad.net/zodb/+bug/544305 - When using using a ClientStorage in a Storage server, there was a threading bug that caused clients to get disconnected. - On Mac OS X, clients that connected and disconnected quickly could cause a ZEO server to stop accepting connections, due to a failure to catch errors in the initial part of the connection process. The failure to properly handle exceptions while accepting connections is potentially problematic on other platforms. Fixes: https://bugs.launchpad.net/zodb/+bug/135108 - Object state management wasn't done correctly when classes implemented custom _p_deavtivate methods.

The components you get with the ZODB release are as follows: - Core ZODB, including the persistence machinery - Standard storages such as FileStorage - The persistent BTrees modules - ZEO, for scalability needs - documentation (needs a lot more work) Our primary development platforms are Linux, Mac OS X, and Windows XP. The test suite should pass without error on all of these platforms, although it can take a long time on Windows -- longer if you use ZoneAlarm. Many particularly slow tests are skipped unless you pass --all as an argument to test.py. Compatibility ============= ZODB 3.10 requires Python 2.5 or later. Note -- When using ZEO and upgrading from Python 2.4, you need to upgrade clients and servers at the same time, or upgrade clients first and then servers. Clients running Python 2.5 or 2.6 will work with servers running Python 2.4. Clients running Python 2.4 won't work properly with servers running Python 2.5 or later due to changes in the way Python implements exceptions. ZODB ZEO clients from ZODB 3.2 on can talk to ZODB 3.10 servers. ZODB ZEO 3.10 Clients can talk to ZODB 3.8, 3.9, and 3.10 ZEO servers. Note -- ZEO 3.10 servers don't support undo for older clients. Prerequisites ============= You must have Python installed. If you're using a system Python install, make sure development support is installed too. You also need the transaction, zc.lockfile, ZConfig, zdaemon, zope.event, zope.interface, zope.proxy and zope.testing packages. If you don't have them and you can connect to the Python Package Index, then these will be installed for you if you don't have them. Installation ============ ZODB is released as a distutils package. The easiest ways to build and install it are to use `easy_install `_, or `zc.buildout `_. To install by hand, first install the dependencies, ZConfig, zdaemon, zope.interface, zope.proxy and zope.testing. These can be found in the `Python Package Index `_. To run the tests, use the test setup command:: python setup.py test It will download dependencies if needed. If this happens, ou may get an import error when the test command gets to looking for tests. Try running the test command a second time and you should see the tests run. :: python setup.py test To install, use the install command:: python setup.py install Testing for Developers ====================== The ZODB checkouts are `buildouts `_. When working from a ZODB checkout, first run the bootstrap.py script to initialize the buildout: % python bootstrap.py and then use the buildout script to build ZODB and gather the dependencies: % bin/buildout This creates a test script: % bin/test -v This command will run all the tests, printing a single dot for each test. When it finishes, it will print a test summary. The exact number of tests can vary depending on platform and available third-party libraries.:: Ran 1182 tests in 241.269s OK The test script has many more options. Use the ``-h`` or ``--help`` options to see a file list of options. The default test suite omits several tests that depend on third-party software or that take a long time to run. To run all the available tests use the ``--all`` option. Running all the tests takes much longer.:: Ran 1561 tests in 1461.557s OK Maintenance scripts ------------------- Several scripts are provided with the ZODB and can help for analyzing, debugging, checking for consistency, summarizing content, reporting space used by objects, doing backups, artificial load testing, etc. Look at the ZODB/script directory for more informations. History ======= The historical version numbering schemes for ZODB and ZEO are complicated. Starting with ZODB 3.4, the ZODB and ZEO version numbers are the same. In the ZODB 3.1 through 3.3 lines, the ZEO version number was "one smaller" than the ZODB version number; e.g., ZODB 3.2.7 included ZEO 2.2.7. ZODB and ZEO were distinct releases prior to ZODB 3.1, and had independent version numbers. Historically, ZODB was distributed as a part of the Zope application server. Jim Fulton's paper at the Python conference in 2000 described a version of ZODB he called ZODB 3, based on an earlier persistent object system called BoboPOS. The earliest versions of ZODB 3 were released with Zope 2.0. Andrew Kuchling extracted ZODB from Zope 2.4.1 and packaged it for use by standalone Python programs. He called this version "StandaloneZODB". Andrew's guide to using ZODB is included in the Doc directory. This version of ZODB was hosted at http://sf.net/projects/zodb. It supported Python 1.5.2, and might still be of interest to users of this very old Python version. Zope Corporation released a version of ZODB called "StandaloneZODB 1.0" in Feb. 2002. This release was based on Andrew's packaging, but built from the same CVS repository as Zope. It is roughly equivalent to the ZODB in Zope 2.5. Why not call the current release StandaloneZODB? The name StandaloneZODB is a bit of a mouthful. The standalone part of the name suggests that the Zope version is the real version and that this is an afterthought, which isn't the case. So we're calling this release "ZODB". We also worked on a ZODB4 package for a while and made a couple of alpha releases. We've now abandoned that effort, because we didn't have the resources to pursue ot while also maintaining ZODB(3).

The client cache allows reads to be done from local disk rather than by remote access to the storage server. The cache may be persistent or transient. If the cache is persistent, then the cache file is retained for use after process restarts. A non- persistent cache uses a temporary file. The client cache is managed in a single file, of the specified size. The life of the cache is as follows: - The cache file is opened (if it already exists), or created and set to the specified size. - Cache records are written to the cache file, as transactions commit locally, and as data are loaded from the server. - Writes are to "the current file position". This is a pointer that travels around the file, circularly. After a record is written, the pointer advances to just beyond it. Objects starting at the current file position are evicted, as needed, to make room for the next record written. A distinct index file is not created, although indexing structures are maintained in memory while a ClientStorage is running. When a persistent client cache file is reopened, these indexing structures are recreated by analyzing the file contents. Persistent cache files are created in the directory named in the ``var`` argument to the ClientStorage, or if ``var`` is None, in the current working directory. Persistent cache files have names of the form:: client-storage.zec where: client -- the client name, as given by the ClientStorage's ``client`` argument storage -- the storage name, as given by the ClientStorage's ``storage`` argument; this is typically a string denoting a small integer, "1" by default For example, the cache file for client '8881' and storage 'spam' is named "8881-spam.zec".

Introduction ------------ ZEO (Zope Enterprise Objects) is a client-server system for sharing a single storage among many clients. Normally, a ZODB storage can only be used by a single process. When you use ZEO, the storage is opened in the ZEO server process. Client programs connect to this process using a ZEO ClientStorage. ZEO provides a consistent view of the database to all clients. The ZEO client and server communicate using a custom RPC protocol layered on top of TCP. There are several configuration options that affect the behavior of a ZEO server. This section describes how a few of these features working. Subsequent sections describe how to configure every option. Client cache ~~~~~~~~~~~~ Each ZEO client keeps an on-disk cache of recently used objects to avoid fetching those objects from the server each time they are requested. It is usually faster to read the objects from disk than it is to fetch them over the network. The cache can also provide read-only copies of objects during server outages. The cache may be persistent or transient. If the cache is persistent, then the cache files are retained for use after process restarts. A non-persistent cache uses temporary files that are removed when the client storage is closed. The client cache size is configured when the ClientStorage is created. The default size is 20MB, but the right size depends entirely on the particular database. Setting the cache size too small can hurt performance, but in most cases making it too big just wastes disk space. The document "Client cache tracing" describes how to collect a cache trace that can be used to determine a good cache size. ZEO uses invalidations for cache consistency. Every time an object is modified, the server sends a message to each client informing it of the change. The client will discard the object from its cache when it receives an invalidation. These invalidations are often batched. Each time a client connects to a server, it must verify that its cache contents are still valid. (It did not receive any invalidation messages while it was disconnected.) There are several mechanisms used to perform cache verification. In the worst case, the client sends the server a list of all objects in its cache along with their timestamps; the server sends back an invalidation message for each stale object. The cost of verification is one drawback to making the cache too large. Note that every time a client crashes or disconnects, it must verify its cache. Every time a server crashes, all of its clients must verify their caches. The cache verification process is optimized in two ways to eliminate costs when restarting clients and servers. Each client keeps the timestamp of the last invalidation message it has seen. When it connects to the server, it checks to see if any invalidation messages were sent after that timestamp. If not, then the cache is up-to-date and no further verification occurs. The other optimization is the invalidation queue, described below. Invalidation queue ~~~~~~~~~~~~~~~~~~ The ZEO server keeps a queue of recent invalidation messages in memory. When a client connects to the server, it sends the timestamp of the most recent invalidation message it has received. If that message is still in the invalidation queue, then the server sends the client all the missing invalidations. This is often cheaper than perform full cache verification. The default size of the invalidation queue is 100. If the invalidation queue is larger, it will be more likely that a client that reconnects will be able to verify its cache using the queue. On the other hand, a large queue uses more memory on the server to store the message. Invalidation messages tend to be small, perhaps a few hundred bytes each on average; it depends on the number of objects modified by a transaction. Transaction timeouts ~~~~~~~~~~~~~~~~~~~~ A ZEO server can be configured to timeout a transaction if it takes too long to complete. Only a single transaction can commit at a time; so if one transaction takes too long, all other clients will be delayed waiting for it. In the extreme, a client can hang during the commit process. If the client hangs, the server will be unable to commit other transactions until it restarts. A well-behaved client will not hang, but the server can be configured with a transaction timeout to guard against bugs that cause a client to hang. If any transaction exceeds the timeout threshold, the client's connection to the server will be closed and the transaction aborted. Once the transaction is aborted, the server can start processing other client's requests. Most transactions should take very little time to commit. The timer begins for a transaction after all the data has been sent to the server. At this point, the cost of commit should be dominated by the cost of writing data to disk; it should be unusual for a commit to take longer than 1 second. A transaction timeout of 30 seconds should tolerate heavy load and slow communications between client and server, while guarding against hung servers. When a transaction times out, the client can be left in an awkward position. If the timeout occurs during the second phase of the two phase commit, the client will log a panic message. This should only cause problems if the client transaction involved multiple storages. If it did, it is possible that some storages committed the client changes and others did not. Connection management ~~~~~~~~~~~~~~~~~~~~~ A ZEO client manages its connection to the ZEO server. If it loses the connection, it attempts to reconnect. While it is disconnected, it can satisfy some reads by using its cache. The client can be configured to wait for a connection when it is created or to return immediately and provide data from its persistent cache. It usually simplifies programming to have the client wait for a connection on startup. When the client is disconnected, it polls periodically to see if the server is available. The rate at which it polls is configurable. The client can be configured with multiple server addresses. In this case, it assumes that each server has identical content and will use any server that is available. It is possible to configure the client to accept a read-only connection to one of these servers if no read-write connection is available. If it has a read-only connection, it will continue to poll for a read-write connection. This feature supports the Zope Replication Services product, http://www.zope.com/Products/ZopeProducts/ZRS. In general, it could be used to with a system that arranges to provide hot backups of servers in the case of failure. If a single address resolves to multiple IPv4 or IPv6 addresses, the client will connect to an arbitrary of these addresses. Authentication ~~~~~~~~~~~~~~ ZEO supports optional authentication of client and server using a password scheme similar to HTTP digest authentication (RFC 2069). It is a simple challenge-response protocol that does not send passwords in the clear, but does not offer strong security. The RFC discusses many of the limitations of this kind of protocol. Note that this feature provides authentication only. It does not provide encryption or confidentiality. The challenge-response also produces a session key that is used to generate message authentication codes for each ZEO message. This should prevent session hijacking. Guard the password database as if it contained plaintext passwords. It stores the hash of a username and password. This does not expose the plaintext password, but it is sensitive nonetheless. An attacker with the hash can impersonate the real user. This is a limitation of the simple digest scheme. The authentication framework allows third-party developers to provide new authentication modules. Installing software ------------------- ZEO is distributed as part of the ZODB3 package and with Zope, starting with Zope 2.7. You can download it from http://pypi.python.org/pypi/ZODB3. Configuring server ------------------ The script runzeo.py runs the ZEO server. The server can be configured using command-line arguments or a config file. This document only describes the config file. Run runzeo.py -h to see the list of command-line arguments. The runzeo.py script imports the ZEO package. ZEO must either be installed in Python's site-packages directory or be in a directory on PYTHONPATH. The configuration file specifies the underlying storage the server uses, the address it binds, and a few other optional parameters. An example is:: address zeo.example.com:8090 monitor-address zeo.example.com:8091 path /var/tmp/Data.fs path /var/tmp/zeo.log format %(asctime)s %(message)s This file configures a server to use a FileStorage from /var/tmp/Data.fs. The server listens on port 8090 of zeo.example.com. It also starts a monitor server that lists in port 8091. The ZEO server writes its log file to /var/tmp/zeo.log and uses a custom format for each line. Assuming the example configuration it stored in zeo.config, you can run a server by typing:: python /usr/local/bin/runzeo.py -C zeo.config A configuration file consists of a section and a storage section, where the storage section can use any of the valid ZODB storage types. It may also contain an eventlog configuration. See the document "Configuring a ZODB database" for more information about configuring storages and eventlogs. The zeo section must list the address. All the other keys are optional. address The address at which the server should listen. This can be in the form 'host:port' to signify a TCP/IP connection or a pathname string to signify a Unix domain socket connection (at least one '/' is required). A hostname may be a DNS name or a dotted IP address. If the hostname is omitted, the platform's default behavior is used when binding the listening socket ('' is passed to socket.bind() as the hostname portion of the address). read-only Flag indicating whether the server should operate in read-only mode. Defaults to false. Note that even if the server is operating in writable mode, individual storages may still be read-only. But if the server is in read-only mode, no write operations are allowed, even if the storages are writable. Note that pack() is considered a read-only operation. invalidation-queue-size The storage server keeps a queue of the objects modified by the last N transactions, where N == invalidation_queue_size. This queue is used to speed client cache verification when a client disconnects for a short period of time. monitor-address The address at which the monitor server should listen. If specified, a monitor server is started. The monitor server provides server statistics in a simple text format. This can be in the form 'host:port' to signify a TCP/IP connection or a pathname string to signify a Unix domain socket connection (at least one '/' is required). A hostname may be a DNS name or a dotted IP address. If the hostname is omitted, the platform's default behavior is used when binding the listening socket ('' is passed to socket.bind() as the hostname portion of the address). transaction-timeout The maximum amount of time to wait for a transaction to commit after acquiring the storage lock, specified in seconds. If the transaction takes too long, the client connection will be closed and the transaction aborted. authentication-protocol The name of the protocol used for authentication. The only protocol provided with ZEO is "digest," but extensions may provide other protocols. authentication-database The path of the database containing authentication credentials. authentication-realm The authentication realm of the server. Some authentication schemes use a realm to identify the logic set of usernames that are accepted by this server. Configuring clients ------------------- The ZEO client can also be configured using ZConfig. The ZODB.config module provides several function for opening a storage based on its configuration. - ZODB.config.storageFromString() - ZODB.config.storageFromFile() - ZODB.config.storageFromURL() The ZEO client configuration requires the server address be specified. Everything else is optional. An example configuration is:: server zeo.example.com:8090 The other configuration options are listed below. storage The name of the storage that the client wants to use. If the ZEO server serves more than one storage, the client selects the storage it wants to use by name. The default name is '1', which is also the default name for the ZEO server. cache-size The maximum size of the client cache, in bytes. name The storage name. If unspecified, the address of the server will be used as the name. client Enables persistent cache files. The string passed here is used to construct the cache filenames. If it is not specified, the client creates a temporary cache that will only be used by the current object. var The directory where persistent cache files are stored. By default cache files, if they are persistent, are stored in the current directory. min-disconnect-poll The minimum delay in seconds between attempts to connect to the server, in seconds. Defaults to 5 seconds. max-disconnect-poll The maximum delay in seconds between attempts to connect to the server, in seconds. Defaults to 300 seconds. wait A boolean indicating whether the constructor should wait for the client to connect to the server and verify the cache before returning. The default is true. read-only A flag indicating whether this should be a read-only storage, defaulting to false (i.e. writing is allowed by default). read-only-fallback A flag indicating whether a read-only remote storage should be acceptable as a fallback when no writable storages are available. Defaults to false. At most one of read_only and read_only_fallback should be true. realm The authentication realm of the server. Some authentication schemes use a realm to identify the logic set of usernames that are accepted by this server. A ZEO client can also be created by calling the ClientStorage constructor explicitly. For example:: from ZEO.ClientStorage import ClientStorage storage = ClientStorage(("zeo.example.com", 8090)) Running the ZEO server as a daemon ---------------------------------- In an operational setting, you will want to run the ZEO server a daemon process that is restarted when it dies. The zdaemon package provides two tools for running daemons: zdrun.py and zdctl.py. You can find zdaemon and it's documentation at http://pypi.python.org/pypi/zdaemon. Rotating log files ~~~~~~~~~~~~~~~~~~ ZEO will re-initialize its logging subsystem when it receives a SIGUSR2 signal. If you are using the standard event logger, you should first rename the log file and then send the signal to the server. The server will continue writing to the renamed log file until it receives the signal. After it receives the signal, the server will create a new file with the old name and write to it. Tools ----- There are a few scripts that may help running a ZEO server. The zeopack.py script connects to a server and packs the storage. It can be run as a cron job. The zeoup.py script attempts to connect to a ZEO server and verify that is is functioning. The zeopasswd.py script manages a ZEO servers password database. Diagnosing problems ------------------- If an exception occurs on the server, the server will log a traceback and send an exception to the client. The traceback on the client will show a ZEO protocol library as the source of the error. If you need to diagnose the problem, you will have to look in the server log for the rest of the traceback. zope2.13-2.13.21/source/ZODB3/doc/HOWTO-Blobs-NFS.txt0000644000175000017500000000545012214017464020156 0ustar arnauarnau=========================================== How to use NFS to make Blobs more efficient =========================================== :Author: Christian Theune Overview ======== When handling blobs, the biggest goal is to avoid writing operations that require the blob data to be transferred using up IO resources. When bringing a blob into the system, at least one O(N) operation has to happen, e.g. when the blob is uploaded via a network server. The blob should be extracted as a file on the final storage volume as early as possible, avoiding further copies. In a ZEO setup, all data is stored on a networked server and passed to it using zrpc. This is a major problem for handling blobs, because it will lock all transactions from committing when storing a single large blob. As a default, this mechanism works but is not recommended for high-volume installations. Shared filesystem ================= The solution for the transfer problem is to setup various storage parameters so that blobs are always handled on a single volume that is shared via network between ZEO servers and clients. Step 1: Setup a writable shared filesystem for ZEO server and client -------------------------------------------------------------------- On the ZEO server, create two directories on the volume that will be used by this setup (assume the volume is accessible via $SERVER/): - $SERVER/blobs - $SERVER/tmp Then export the $SERVER directory using a shared network filesystem like NFS. Make sure it's writable by the ZEO clients. Assume the exported directory is available on the client as $CLIENT. Step 2: Application temporary directories ----------------------------------------- Applications (i.e. Zope) will put uploaded data in a temporary directory first. Adjust your TMPDIR, TMP or TEMP environment variable to point to the shared filesystem: $ export TMPDIR=$CLIENT/tmp Step 3: ZEO client caches ------------------------- Edit the file `zope.conf` on the ZEO client and adjust the configuration of the `zeoclient` storage with two new variables:: blob-dir = $CLIENT/blobs blob-cache-writable = yes Step 4: ZEO server ------------------ Edit the file `zeo.conf` on the ZEO server to configure the blob directory. Assuming the published storage of the ZEO server is a file storage, then the configuration should look like this:: path $INSTANCE/var/Data.fs blob-dir $SERVER/blobs (Remember to manually replace $SERVER and $CLIENT with the exported directory as accessible by either the ZEO server or the ZEO client.) Conclusion ---------- At this point, after restarting your ZEO server and clients, the blob directory will be shared and a minimum amount of IO will occur when working with blobs. zope2.13-2.13.21/source/ZODB3/doc/zeo-client-cache-tracing.txt0000644000175000017500000001661312214017464022335 0ustar arnauarnauZEO Client Cache Tracing ======================== An important question for ZEO users is: how large should the ZEO client cache be? ZEO 2 (as of ZEO 2.0b2) has a new feature that lets you collect a trace of cache activity and tools to analyze this trace, enabling you to make an informed decision about the cache size. Don't confuse the ZEO client cache with the Zope object cache. The ZEO client cache is only used when an object is not in the Zope object cache; the ZEO client cache avoids roundtrips to the ZEO server. Enabling Cache Tracing ---------------------- To enable cache tracing, you must use a persistent cache (specify a ``client`` name), and set the environment variable ZEO_CACHE_TRACE to a non-empty value. The path to the trace file is derived from the path to the persistent cache file by appending ".trace". If the file doesn't exist, ZEO will try to create it. If the file does exist, it's opened for appending (previous trace information is not overwritten). If there are problems with the file, a warning message is logged. To start or stop tracing, the ZEO client process (typically a Zope application server) must be restarted. The trace file can grow pretty quickly; on a moderately loaded server, we observed it growing by 7 MB per hour. The file consists of binary records, each 34 bytes long if 8-byte oids are in use; a detailed description of the record lay-out is given in stats.py. No sensitive data is logged: data record sizes (but not data records), and binary object and transaction ids are logged, but no object pickles, object types or names, user names, transaction comments, access paths, or machine information (such as machine name or IP address) are logged. Analyzing a Cache Trace ----------------------- The stats.py command-line tool is the first-line tool to analyze a cache trace. Its default output consists of two parts: a one-line summary of essential statistics for each segment of 15 minutes, interspersed with lines indicating client restarts, followed by a more detailed summary of overall statistics. The most important statistic is the "hit rate", a percentage indicating how many requests to load an object could be satisfied from the cache. Hit rates around 70% are good. 90% is excellent. If you see a hit rate under 60% you can probably improve the cache performance (and hence your Zope application server's performance) by increasing the ZEO cache size. This is normally configured using key ``cache_size`` in the ``zeoclient`` section of your configuration file. The default cache size is 20 MB, which is small. The stats.py tool shows its command line syntax when invoked without arguments. The tracefile argument can be a gzipped file if it has a .gz extension. It will be read from stdin (assuming uncompressed data) if the tracefile argument is '-'. Simulating Different Cache Sizes -------------------------------- Based on a cache trace file, you can make a prediction of how well the cache might do with a different cache size. The simul.py tool runs a simulation of the ZEO client cache implementation based upon the events read from a trace file. A new simulation is started each time the trace file records a client restart event; if a trace file contains more than one restart event, a separate line is printed for each simulation, and a line with overall statistics is added at the end. Example, assuming the trace file is in /tmp/cachetrace.log:: $ python simul.py -s 4 /tmp/cachetrace.log CircularCacheSimulation, cache size 4,194,304 bytes START TIME DURATION LOADS HITS INVALS WRITES HITRATE EVICTS INUSE Jul 22 22:22 39:09 3218856 1429329 24046 41517 44.4% 40776 99.8 This shows that with a 4 MB cache size, the cache hit rate is 44.4%, the percentage 1429329 (number of cache hits) is of 3218856 (number of load requests). The cache simulated 40776 evictions, to make room for new object states. At the end, 99.8% of the bytes reserved for the cache file were in use to hold object state (the remaining 0.2% consists of "holes", bytes freed by object eviction and not yet reused to hold another object's state). Let's try this again with an 8 MB cache:: $ python simul.py -s 8 /tmp/cachetrace.log CircularCacheSimulation, cache size 8,388,608 bytes START TIME DURATION LOADS HITS INVALS WRITES HITRATE EVICTS INUSE Jul 22 22:22 39:09 3218856 2182722 31315 41517 67.8% 40016 100.0 That's a huge improvement in hit rate, which isn't surprising since these are very small cache sizes. The default cache size is 20 MB, which is still on the small side:: $ python simul.py /tmp/cachetrace.log CircularCacheSimulation, cache size 20,971,520 bytes START TIME DURATION LOADS HITS INVALS WRITES HITRATE EVICTS INUSE Jul 22 22:22 39:09 3218856 2982589 37922 41517 92.7% 37761 99.9 Again a very nice improvement in hit rate, and there's not a lot of room left for improvement. Let's try 100 MB:: $ python simul.py -s 100 /tmp/cachetrace.log CircularCacheSimulation, cache size 104,857,600 bytes START TIME DURATION LOADS HITS INVALS WRITES HITRATE EVICTS INUSE Jul 22 22:22 39:09 3218856 3218741 39572 41517 100.0% 22778 100.0 It's very unusual to see a hit rate so high. The application here frequently modified a very large BTree, so given enough cache space to hold the entire BTree it rarely needed to ask the ZEO server for data: this application reused the same objects over and over. More typical is that a substantial number of objects will be referenced only once. Whenever an object turns out to be loaded only once, it's a pure loss for the cache: the first (and only) load is a cache miss; storing the object evicts other objects, possibly causing more cache misses; and the object is never loaded again. If, for example, a third of the objects are loaded only once, it's quite possible for the theoretical maximum hit rate to be 67%, no matter how large the cache. The simul.py script also contains code to simulate different cache strategies. Since none of these are implemented, and only the default cache strategy's code has been updated to be aware of MVCC, these are not further documented here. Simulation Limitations ---------------------- The cache simulation is an approximation, and actual hit rate may be higher or lower than the simulated result. These are some factors that inhibit exact simulation: - The simulator doesn't try to emulate versions. If the trace file contains loads and stores of objects in versions, the simulator treats them as if they were loads and stores of non-version data. - Each time a load of an object O in the trace file was a cache hit, but the simulated cache has evicted O, the simulated cache has no way to repair its knowledge about O. This is more frequent when simulating caches smaller than the cache used to produce the trace file. When a real cache suffers a cache miss, it asks the ZEO server for the needed information about O, and saves O in the client cache. The simulated cache doesn't have a ZEO server to ask, and O continues to be absent in the simulated cache. Further requests for O will continue to be simulated cache misses, although in a real cache they'll likely be cache hits.

Applications can take advantage of object database features with few, if any, changes to application logic. ZODB includes features such as a plugable storage interface, rich transaction support, and undo. .. contents:: ==== ZODB ==== Introduction ============ The ZODB package provides a set of tools for using the Zope Object Database (ZODB). The components you get with the ZODB release are as follows: - Core ZODB, including the persistence machinery - Standard storages such as FileStorage - The persistent BTrees modules - ZEO, for scalability needs - documentation (needs a lot more work) Our primary development platforms are Linux, Mac OS X, and Windows XP. The test suite should pass without error on all of these platforms, although it can take a long time on Windows -- longer if you use ZoneAlarm. Many particularly slow tests are skipped unless you pass --all as an argument to test.py. Compatibility ============= ZODB 3.10 requires Python 2.5 or later. Note -- When using ZEO and upgrading from Python 2.4, you need to upgrade clients and servers at the same time, or upgrade clients first and then servers. Clients running Python 2.5 or 2.6 will work with servers running Python 2.4. Clients running Python 2.4 won't work properly with servers running Python 2.5 or later due to changes in the way Python implements exceptions. ZODB ZEO clients from ZODB 3.2 on can talk to ZODB 3.10 servers. ZODB ZEO 3.10 Clients can talk to ZODB 3.8, 3.9, and 3.10 ZEO servers. Note -- ZEO 3.10 servers don't support undo for older clients. Prerequisites ============= You must have Python installed. If you're using a system Python install, make sure development support is installed too. You also need the transaction, zc.lockfile, ZConfig, zdaemon, zope.event, zope.interface, zope.proxy and zope.testing packages. If you don't have them and you can connect to the Python Package Index, then these will be installed for you if you don't have them. Installation ============ ZODB is released as a distutils package. The easiest ways to build and install it are to use `easy_install `_, or `zc.buildout `_. To install by hand, first install the dependencies, ZConfig, zdaemon, zope.interface, zope.proxy and zope.testing. These can be found in the `Python Package Index `_. To run the tests, use the test setup command:: python setup.py test It will download dependencies if needed. If this happens, ou may get an import error when the test command gets to looking for tests. Try running the test command a second time and you should see the tests run. :: python setup.py test To install, use the install command:: python setup.py install Testing for Developers ====================== The ZODB checkouts are `buildouts `_. When working from a ZODB checkout, first run the bootstrap.py script to initialize the buildout: % python bootstrap.py and then use the buildout script to build ZODB and gather the dependencies: % bin/buildout This creates a test script: % bin/test -v This command will run all the tests, printing a single dot for each test. When it finishes, it will print a test summary. The exact number of tests can vary depending on platform and available third-party libraries.:: Ran 1182 tests in 241.269s OK The test script has many more options. Use the ``-h`` or ``--help`` options to see a file list of options. The default test suite omits several tests that depend on third-party software or that take a long time to run. To run all the available tests use the ``--all`` option. Running all the tests takes much longer.:: Ran 1561 tests in 1461.557s OK Maintenance scripts ------------------- Several scripts are provided with the ZODB and can help for analyzing, debugging, checking for consistency, summarizing content, reporting space used by objects, doing backups, artificial load testing, etc. Look at the ZODB/script directory for more informations. History ======= The historical version numbering schemes for ZODB and ZEO are complicated. Starting with ZODB 3.4, the ZODB and ZEO version numbers are the same. In the ZODB 3.1 through 3.3 lines, the ZEO version number was "one smaller" than the ZODB version number; e.g., ZODB 3.2.7 included ZEO 2.2.7. ZODB and ZEO were distinct releases prior to ZODB 3.1, and had independent version numbers. Historically, ZODB was distributed as a part of the Zope application server. Jim Fulton's paper at the Python conference in 2000 described a version of ZODB he called ZODB 3, based on an earlier persistent object system called BoboPOS. The earliest versions of ZODB 3 were released with Zope 2.0. Andrew Kuchling extracted ZODB from Zope 2.4.1 and packaged it for use by standalone Python programs. He called this version "StandaloneZODB". Andrew's guide to using ZODB is included in the Doc directory. This version of ZODB was hosted at http://sf.net/projects/zodb. It supported Python 1.5.2, and might still be of interest to users of this very old Python version. Zope Corporation released a version of ZODB called "StandaloneZODB 1.0" in Feb. 2002. This release was based on Andrew's packaging, but built from the same CVS repository as Zope. It is roughly equivalent to the ZODB in Zope 2.5. Why not call the current release StandaloneZODB? The name StandaloneZODB is a bit of a mouthful. The standalone part of the name suggests that the Zope version is the real version and that this is an afterthought, which isn't the case. So we're calling this release "ZODB". We also worked on a ZODB4 package for a while and made a couple of alpha releases. We've now abandoned that effort, because we didn't have the resources to pursue ot while also maintaining ZODB(3).

Local Variables: mode: indented-text indent-tabs-mode: nil sentence-end-double-space: t fill-column: 70 End: ================ Change History ================ 3.10.5 (2011-11-19) =================== Bugs Fixed ---------- - Conflict resolution failed when state included cross-database persistent references with classes that couldn't be imported. 3.10.4 (2011-11-17) =================== Bugs Fixed ---------- - Conflict resolution failed when state included persistent references with classes that couldn't be imported. 3.10.3 (2011-04-12) =================== Bugs Fixed ---------- - "activity monitor not updated for subconnections when connection returned to pool" https://bugs.launchpad.net/zodb/+bug/737198 - "Blob temp file get's removed before it should", https://bugs.launchpad.net/zodb/+bug/595378 A way this to happen is that a transaction is aborted after the commit process has started. I don't know how this would happen in the wild. In 3.10.3, the ZEO tpc_abort call to the server is changed to be synchronous, which should address this case. Maybe there's another case. Performance enhancements ------------------------ - Improved ZEO client cache implementation to make it less likely to evict objects that are being used. - Small (possibly negligable) reduction in CPU in ZEO storage servers to service object loads and in networking code. 3.10.2 (2011-02-12) =================== Bugs Fixed ---------- - 3.10 introduced an optimization to try to address BTree conflict errors arrising for basing BTree keys on object ids. The optimization caused object ids allocated in aborted transactions to be reused. Unfortunately, this optimzation led to some rather severe failures in some applications. The symptom is a conflict error in which one of the serials mentioned is zero. This optimization has been removed. See (for example): https://bugs.launchpad.net/zodb/+bug/665452 - ZEO server transaction timeouts weren't logged as critical. https://bugs.launchpad.net/zodb/+bug/670986 3.10.1 (2010-10-27) =================== Bugs Fixed ---------- - When a transaction rolled back a savepoint after adding objects and subsequently added more objects and committed, an error could be raised "ValueError: A different object already has the same oid" causing the transaction to fail. Worse, this could leave a database in a state where subsequent transactions in the same process would fail. https://bugs.launchpad.net/zodb/+bug/665452 - Unix domain sockets didn't work for ZEO (since the addition of IPv6 support). https://bugs.launchpad.net/zodb/+bug/663259 - Removed a missfeature that can cause performance problems when using an external garbage collector with ZEO. When objects were deleted from a storage, invalidations were sent to clients. This makes no sense. It's wildly unlikely that the other connections/clients have copies of the garbage. In normal storage garbage collection, we don't send invalidations. There's no reason to send them when an external garbage collector is used. - ZEO client cache simulation misshandled invalidations causing incorrect statistics and errors. 3.10.0 (2010-10-08) =================== New Features ------------ - There are a number of performance enhancements for ZEO storage servers. - FileStorage indexes use a new format. They are saved and loaded much faster and take less space. Old indexes can still be read, but new indexes won't be readable by older versions of ZODB. - The API for undoing multiple transactions has changed. To undo multiple transactions in a single transaction, pass a list of transaction identifiers to a database's undoMultiple method. Calling a database's undo method multiple times in the same transaction now raises an exception. - The ZEO protocol for undo has changed. The only user-visible consequence of this is that when ZODB 3.10 ZEO servers won't support undo for older clients. - The storage API (IStorage) has been tightened. Now, storages should raise a StorageTransactionError when invalid transactions are passed to tpc_begin, tpc_vote, or tpc_finish. - ZEO clients (``ClientStorage`` instances) now work in forked processes, including those created via ``multiprocessing.Process`` instances. - Broken objects now provide the IBroken interface. - As a convenience, you can now pass an integer port as an address to the ZEO ClientStorage constructor. - As a convenience, there's a new ``client`` function in the ZEO package for constructing a ClientStorage instance. It takes the same arguments as the ClientStorage constructor. - DemoStorages now accept constructor athuments, close_base_on_close and close_changes_on_close, to control whether underlying storages are closed when the DemoStorage is closed. https://bugs.launchpad.net/zodb/+bug/118512 - Removed the dependency on zope.proxy. - Removed support for the _p_independent mini framework, which was made moot by the introduction of multi-version concurrency control several years ago. - Added support for the transaction retry convenience (transaction-manager attempts method) introduced in the ``transaction`` 1.1.0 release. - Enhanced the database opening conveniences: - You can now pass storage keyword arguments to ZODB.DB and ZODB.connection. - You can now pass None (rather than a storage or file name) to get a database with a mapping storage. - Databases now warn when committing very large records (> 16MB). This is to try to warn people of likely design mistakes. There is a new option (large_record_size/large-record-size) to control the record size at which the warning is issued. - Added support for wrapper storages that transform pickle data. Applications for this include compression and encryption. An example wrapper storage implementation, ZODB.tests.hexstorage, was included for testing. It is important that storage implementations not assume that storages contain pickles. Renamed IStorageDB to IStorageWrapper and expanded it to provide methods for transforming and untransforming data records. Storages implementations should use these methods to get pickle data from stored records. - Deprecated ZODB.interfaces.StorageStopIteration. Storage iterator implementations should just raise StopIteration, which means they can now be implemented as generators. - The filestorage packer configuration option noe accepts values of the form ``modname:expression``, allowing the use of packer factories with options. - Added a new API that allows applications to make sure that current data are read. For example, with:: self._p_jar.readCurrent(ob) A conflict error will be raised if the version of ob read by the transaction isn't current when the transaction is committed. Normally, ZODB only assures that objects read are consistent, but not necessarily up to date. Checking whether an object is up to date is important when information read from one object is used to update another. BTrees are an important case of reading one object to update another. Internal nodes are read to decide which leave notes are updated when a BTree is updated. BTrees now use this new API to make sure that internal nodes are up to date on updates. - When transactions are aborted, new object ids allocated during the transaction are saved and used in subsequent transactions. This can help in situations where object ids are used as BTree keys and the sequential allocation of object ids leads to conflict errors. - ZEO servers now support a server_status method for for getting information on the number of clients, lock requests and general statistics. - ZEO clients now support a client_label constructor argument and client-label configuration-file option to specify a label for a client in server logs. This makes it easier to identify specific clients corresponding to server log entries, especially when there are multiple clients originating from the same machine. - Improved ZEO server commit lock logging. Now, locking activity is logged at the debug level until the number of waiting lock requests gets above 3. Log at the critical level when the number of waiting lock requests gets above 9. - The file-storage backup script, repozo, will now create a backup index file if an output file name is given via the --output/-o option. - Added a '--kill-old-on-full' argument to the repozo backup options: if passed, remove any older full or incremental backup files from the repository after doing a full backup. (https://bugs.launchpad.net/zope2/+bug/143158) - The mkzeoinst script has been moved to a separate project: http://pypi.python.org/pypi/zope.mkzeoinstance and is no-longer included with ZODB. - Removed untested unsupported dbmstorage fossile. - ZEO servers no longer log their pids in every log message. It's just not interesting. :) Bugs fixed ---------- - When a pool timeout was specified for a database and old connections were removed due to timing out, an error occured due to a bug in the connection cleanup logic. - When multi-database connections were no longer used and cleaned up, their subconnections weren't cleaned up properly. - ZEO didn't work with IPv6 addrsses. Added IPv6 support contributed by Martin v. |Lowis|. - A file storage bug could cause ZEO clients to have incorrect information about current object revisions after reconnecting to a database server. - Updated the 'repozo --kill-old-on-full' option to remove any '.index' files corresponding to backups being removed. - ZEO extension methods failed when a client reconnected to a storage. (https://bugs.launchpad.net/zodb/+bug/143344) - Clarified the return Value for lastTransaction in the case when there aren't any transactions. Now a string of 8 nulls (aka "z64") is specified. - Setting _p_changed on a blob wo actually writing anything caused an error. (https://bugs.launchpad.net/zodb/+bug/440234) - The verbose mode of the fstest was broken. (https://bugs.launchpad.net/zodb/+bug/475996) - Object ids created in a savepoint that is rolled back wren't being reused. (https://bugs.launchpad.net/zodb/+bug/588389) - Database connections didn't invalidate cache entries when conflict errors were raised in response to checkCurrentSerialInTransaction errors. Normally, this shouldn't be a problem, since there should be pending invalidations for these oids which will cause the object to be invalidated. There have been issues with ZEO persistent cache management that have caused out of date data to remain in the cache. (It's possible that the last of these were addressed in the 3.10.0b5.) Invalidating read data when there is a conflict error provides some extra insurance. - The interface, ZODB.interfaces.IStorage was incorrect. The store method should never return a sequence of oid and serial pairs. - When a demo storage push method was used to create a new demo storage and the new storage was closed, the original was (incorrectly) closed. - There were numerous bugs in the ZEO cache tracing and analysis code. Cache simulation, while not perfect, seems to be much more accurate now than it was before. The ZEO cache trace statistics and simulation scripts have been given more descriptive names and moved to the ZEO scripts package. - BTree sets and tree sets didn't correctly check values passed to update or to constructors, causing Python to exit under certain circumstances. - Fixed bug in copying a BTrees.Length instance. (https://bugs.launchpad.net/zodb/+bug/516653) - Fixed a serious bug that caused cache failures when run with Python optimization turned on. https://bugs.launchpad.net/zodb/+bug/544305 - When using using a ClientStorage in a Storage server, there was a threading bug that caused clients to get disconnected. - On Mac OS X, clients that connected and disconnected quickly could cause a ZEO server to stop accepting connections, due to a failure to catch errors in the initial part of the connection process. The failure to properly handle exceptions while accepting connections is potentially problematic on other platforms. Fixes: https://bugs.launchpad.net/zodb/+bug/135108 - Object state management wasn't done correctly when classes implemented custom _p_deavtivate methods.

In this state, the _p_changed attribute is non-None and false and the _p_jar attribute is None. - Saved The object has been saved and has not been changed since it was saved. In this state, the _p_changed attribute is non-None and false and the _p_jar attribute is set to a data manager. - Sticky This state is identical to the saved state except that the object cannot transition to the ghost state. This is a special state used by C methods of persistent objects to make sure that state is not unloaded in the middle of computation. In this state, the _p_changed attribute is non-None and false and the _p_jar attribute is set to a data manager. There is no Python API for detecting whether an object is in the sticky state. - Changed The object has been changed. In this state, the _p_changed attribute is true and the _p_jar attribute is set to a data manager. - Ghost the object is in memory but its state has not been loaded from the database (or its state has been unloaded). In this state, the object doesn't contain any application data. In this state, the _p_changed attribute is None, and the _p_jar attribute is set to the data manager from which the object was obtained. In all the above, _p_oid (the persistent object id) is set when _p_jar first gets set. The following state transitions are possible: - Unsaved -> Saved This transition occurs when an object is saved in the database. This usually happens when an unsaved object is added to (e.g. as an attribute or item of) a saved (or changed) object and the transaction is committed. - Saved -> Changed Sticky -> Changed Ghost -> Changed This transition occurs when someone sets an attribute or sets _p_changed to a true value on a saved, sticky or ghost object. When the transition occurs, the persistent object is required to call the register() method on its data manager, passing itself as the only argument. Prior to ZODB 3.6, setting _p_changed to a true value on a ghost object was ignored (the object remained a ghost, and getting its _p_changed attribute continued to return None). - Saved -> Sticky This transition occurs when C code marks the object as sticky to prevent its deactivation. - Saved -> Ghost This transition occurs when a saved object is deactivated or invalidated. See discussion below. - Sticky -> Saved This transition occurs when C code unmarks the object as sticky to allow its deactivation. - Changed -> Saved This transition occurs when a transaction is committed. After saving the state of a changed object during transaction commit, the data manager sets the object's _p_changed to a non-None false value. - Changed -> Ghost This transition occurs when a transaction is aborted. All changed objects are invalidated by the data manager by an abort. - Ghost -> Saved This transition occurs when an attribute or operation of a ghost is accessed and the object's state is loaded from the database. Note that there is a separate C API that is not included here. The C API requires a specific data layout and defines the sticky state. About Invalidation, Deactivation and the Sticky & Ghost States The sticky state is intended to be a short-lived state, to prevent an object's state from being discarded while we're in C routines. It is an error to invalidate an object in the sticky state. Deactivation is a request that an object discard its state (become a ghost). Deactivation is an optimization, and a request to deactivate may be ignored. There are two equivalent ways to request deactivation: - call _p_deactivate() - set _p_changed to None There are two ways to invalidate an object: call the _p_invalidate() method (preferred) or delete its _p_changed attribute. This cannot be ignored, and is used when semantics require invalidation. Normally, an invalidated object transitions to the ghost state. However, some objects cannot be ghosts. When these objects are invalidated, they immediately reload their state from their data manager, and are then in the saved state. """ _p_jar = Attribute( """The data manager for the object.

At and after ZODB 3.6, setting _p_changed to a true value for a ghost object activates the object; prior to 3.6, setting _p_changed to a true value on a ghost object was ignored. Note that an object can transition to the changed state only if it has a data manager.

They are stored in the self->data dictionary, and are never garbage collected. The klass_items() method returns a sequence of (oid,object) tuples for every Persistent Class, which should make it possible to implement garbage collection in Python if necessary. Regime 2: Ghost Objects There is no benefit to keeping a ghost object which has no external references, therefore a weak reference scheme is used to ensure that ghost objects are removed from memory as soon as possible, when the last external reference is lost. Ghost objects are stored in the self->data dictionary. Normally a dictionary keeps a strong reference on its values, however this reference count is 'stolen'. This weak reference scheme leaves a dangling reference, in the dictionary, when the last external reference is lost. To clean up this dangling reference the persistent object dealloc function calls self->cache->_oid_unreferenced(self->oid). The cache looks up the oid in the dictionary, ensures it points to an object whose reference count is zero, then removes it from the dictionary. Before removing the object from the dictionary it must temporarily resurrect the object in much the same way that class instances are resurrected before their __del__ is called. Since ghost objects are stored under a different regime to non-ghost objects, an extra ghostify function in cPersistenceAPI replaces self->state=GHOST_STATE assignments that were common in other persistent classes (such as BTrees). Regime 3: Non-Ghost Objects Non-ghost objects are stored in two data structures: the dictionary mapping oids to objects and a doubly-linked list that encodes the order in which the objects were accessed. The dictionary reference is borrowed, as it is for ghosts. The list reference is a new reference; the list stores recently used objects, even if they are otherwise unreferenced, to avoid loading the object from the database again. The doubly-link-list nodes contain next and previous pointers linking together the cache and all non-ghost persistent objects. The node embedded in the cache is the home position. On every attribute access a non-ghost object will relink itself just behind the home position in the ring. Objects accessed least recently will eventually find themselves positioned after the home position. Occasionally other nodes are temporarily inserted in the ring as position markers. The cache contains a ring_lock flag which must be set and unset before and after doing so. Only if the flag is unset can the cache assume that all nodes are either his own home node, or nodes from persistent objects. This assumption is useful during the garbage collection process. The number of non-ghost objects is counted in self->non_ghost_count. The garbage collection process consists of traversing the ring, and deactivating (that is, turning into a ghost) every object until self->non_ghost_count is down to the target size, or until it reaches the home position again. Note that objects in the sticky or changed states are still kept in the ring, however they can not be deactivated. The garbage collection process must skip such objects, rather than deactivating them. */ static char cPickleCache_doc_string[] = "Defines the PickleCache used by ZODB Connection objects.\n" "\n" "$Id: cPickleCache.c 116786 2010-09-24 15:12:47Z jim $\n"; #define DONT_USE_CPERSISTENCECAPI #include "cPersistence.h" #include "structmember.h" #include #include #undef Py_FindMethod /* Python 2.4 backward compat */ #if PY_MAJOR_VERSION <= 2 && PY_MINOR_VERSION < 5 #define Py_ssize_t int typedef Py_ssize_t (*lenfunc)(PyObject *); #endif /* Python string objects to speed lookups; set by module init. */ static PyObject *py__p_changed; static PyObject *py__p_deactivate; static PyObject *py__p_jar; static PyObject *py__p_oid; static cPersistenceCAPIstruct *capi; /* This object is the pickle cache.

The test expects a class named `P` to be provided in its globals. The `P` class implements the `Persistent` interface. Test framework -------------- The class `P` needs to behave like `ExampleP`. (Note that the code below is *not* part of the tests.) :: class ExampleP(Persistent): def __init__(self): self.x = 0 def inc(self): self.x += 1 The tests use stub data managers. A data manager is responsible for loading and storing the state of a persistent object. It's stored in the ``_p_jar`` attribute of a persistent object. >>> class DM: ... def __init__(self): ... self.called = 0 ... def register(self, ob): ... self.called += 1 ... def setstate(self, ob): ... ob.__setstate__({'x': 42}) >>> class BrokenDM(DM): ... def register(self,ob): ... self.called += 1 ... raise NotImplementedError ... def setstate(self,ob): ... raise NotImplementedError >>> from persistent import Persistent Test Persistent without Data Manager ------------------------------------ First do some simple tests of a Persistent instance that does not have a data manager (``_p_jar``). >>> p = P() >>> p.x 0 >>> p._p_changed False >>> p._p_state 0 >>> p._p_jar >>> p._p_oid Verify that modifications have no effect on ``_p_state`` of ``_p_changed``. >>> p.inc() >>> p.inc() >>> p.x 2 >>> p._p_changed False >>> p._p_state 0 Try all sorts of different ways to change the object's state. >>> p._p_deactivate() >>> p._p_state 0 >>> p._p_changed = True >>> p._p_state 0 >>> del p._p_changed >>> p._p_changed False >>> p._p_state 0 >>> p.x 2 We can store a size estimation in ``_p_estimated_size``. Its default is 0. The size estimation can be used by a cache associated with the data manager to help in the implementation of its replacement strategy or its size bounds. Of course, the estimated size must not be negative. >>> p._p_estimated_size 0 >>> p._p_estimated_size = 1000 >>> p._p_estimated_size 1024 Huh? Why is the estimated size coming out different than what we put in? The reason is that the size isn't stored exactly. For backward compatibility reasons, the size needs to fit in 24 bits, so, internally, it is adjusted somewhat. >>> p._p_estimated_size = -1 Traceback (most recent call last): .... ValueError: _p_estimated_size must not be negative Test Persistent with Data Manager --------------------------------- Next try some tests of an object with a data manager. The `DM` class is a simple testing stub. >>> p = P() >>> dm = DM() >>> p._p_oid = "00000012" >>> p._p_jar = dm >>> p._p_changed 0 >>> dm.called 0 Modifying the object marks it as changed and registers it with the data manager. Subsequent modifications don't have additional side-effects. >>> p.inc() >>> p._p_changed 1 >>> dm.called 1 >>> p.inc() >>> p._p_changed 1 >>> dm.called 1 It's not possible to deactivate a modified object. >>> p._p_deactivate() >>> p._p_changed 1 It is possible to invalidate it. That's the key difference between deactivation and invalidation. >>> p._p_invalidate() >>> p._p_state -1 Now that the object is a ghost, any attempt to modify it will require that it be unghosted first. The test data manager has the odd property that it sets the object's ``x`` attribute to ``42`` when it is unghosted. >>> p.inc() >>> p.x 43 >>> dm.called 2 You can manually reset the changed field to ``False``, although it's not clear why you would want to do that. The object changes to the ``UPTODATE`` state but retains its modifications. >>> p._p_changed = False >>> p._p_state 0 >>> p._p_changed False >>> p.x 43 >>> p.inc() >>> p._p_changed True >>> dm.called 3 ``__getstate__()`` and ``__setstate__()`` ----------------------------------------- The next several tests cover the ``__getstate__()`` and ``__setstate__()`` implementations. >>> p = P() >>> state = p.__getstate__() >>> isinstance(state, dict) True >>> state['x'] 0 >>> p._p_state 0 Calling setstate always leaves the object in the uptodate state? (I'm not entirely clear on this one.) >>> p.__setstate__({'x': 5}) >>> p._p_state 0 Assigning to a volatile attribute has no effect on the object state. >>> p._v_foo = 2 >>> p.__getstate__() {'x': 5} >>> p._p_state 0 The ``_p_serial`` attribute is not affected by calling setstate. >>> p._p_serial = "00000012" >>> p.__setstate__(p.__getstate__()) >>> p._p_serial '00000012' Change Ghost test ----------------- If an object is a ghost and its ``_p_changed`` is set to ``True`` (any true value), it should activate (unghostify) the object. This behavior is new in ZODB 3.6; before then, an attempt to do ``ghost._p_changed = True`` was ignored. >>> p = P() >>> p._p_jar = DM() >>> p._p_oid = 1 >>> p._p_deactivate() >>> p._p_changed # None >>> p._p_state # ghost state -1 >>> p._p_changed = True >>> p._p_changed 1 >>> p._p_state # changed state 1 >>> p.x 42 Activate, deactivate, and invalidate ------------------------------------ Some of these tests are redundant, but are included to make sure there are explicit and simple tests of ``_p_activate()``, ``_p_deactivate()``, and ``_p_invalidate()``. >>> p = P() >>> p._p_oid = 1 >>> p._p_jar = DM() >>> p._p_deactivate() >>> p._p_state -1 >>> p._p_activate() >>> p._p_state 0 >>> p.x 42 >>> p.inc() >>> p.x 43 >>> p._p_state 1 >>> p._p_invalidate() >>> p._p_state -1 >>> p.x 42 Test failures ------------- The following tests cover various errors cases. When an object is modified, it registers with its data manager. If that registration fails, the exception is propagated and the object stays in the up-to-date state. It shouldn't change to the modified state, because it won't be saved when the transaction commits. >>> p = P() >>> p._p_oid = 1 >>> p._p_jar = BrokenDM() >>> p._p_state 0 >>> p._p_jar.called 0 >>> p._p_changed = 1 Traceback (most recent call last): ... NotImplementedError >>> p._p_jar.called 1 >>> p._p_state 0 Make sure that exceptions that occur inside the data manager's ``setstate()`` method propagate out to the caller. >>> p = P() >>> p._p_oid = 1 >>> p._p_jar = BrokenDM() >>> p._p_deactivate() >>> p._p_state -1 >>> p._p_activate() Traceback (most recent call last): ... NotImplementedError >>> p._p_state -1 Special test to cover layout of ``__dict__`` -------------------------------------------- We once had a bug in the `Persistent` class that calculated an incorrect offset for the ``__dict__`` attribute. It assigned ``__dict__`` and ``_p_jar`` to the same location in memory. This is a simple test to make sure they have different locations. >>> p = P() >>> p.inc() >>> p.inc() >>> 'x' in p.__dict__ True >>> p._p_jar Inheritance and metaclasses --------------------------- Simple tests to make sure it's possible to inherit from the `Persistent` base class multiple times. There used to be metaclasses involved in `Persistent` that probably made this a more interesting test. >>> class A(Persistent): ... pass >>> class B(Persistent): ... pass >>> class C(A, B): ... pass >>> class D(object): ... pass >>> class E(D, B): ... pass >>> a = A() >>> b = B() >>> c = C() >>> d = D() >>> e = E() Also make sure that it's possible to define `Persistent` classes that have a custom metaclass. >>> class alternateMeta(type): ... type >>> class alternate(object): ... __metaclass__ = alternateMeta >>> class mixedMeta(alternateMeta, type): ... pass >>> class mixed(alternate, Persistent): ... pass >>> class mixed(Persistent, alternate): ... pass Basic type structure -------------------- >>> Persistent.__dictoffset__ 0 >>> Persistent.__weakrefoffset__ 0 >>> Persistent.__basicsize__ > object.__basicsize__ True >>> P.__dictoffset__ > 0 True >>> P.__weakrefoffset__ > 0 True >>> P.__dictoffset__ < P.__weakrefoffset__ True >>> P.__basicsize__ > Persistent.__basicsize__ True Slots ----- These are some simple tests of classes that have an ``__slots__`` attribute. Some of the classes should have slots, others shouldn't. >>> class noDict(object): ... __slots__ = ['foo'] >>> class p_noDict(Persistent): ... __slots__ = ['foo'] >>> class p_shouldHaveDict(p_noDict): ... pass >>> p_noDict.__dictoffset__ 0 >>> x = p_noDict() >>> x.foo = 1 >>> x.foo 1 >>> x.bar = 1 Traceback (most recent call last): ... AttributeError: 'p_noDict' object has no attribute 'bar' >>> x._v_bar = 1 Traceback (most recent call last): ... AttributeError: 'p_noDict' object has no attribute '_v_bar' >>> x.__dict__ Traceback (most recent call last): ... AttributeError: 'p_noDict' object has no attribute '__dict__' The various _p_ attributes are unaffected by slots. >>> p._p_oid >>> p._p_jar >>> p._p_state 0 If the most-derived class does not specify >>> p_shouldHaveDict.__dictoffset__ > 0 True >>> x = p_shouldHaveDict() >>> isinstance(x.__dict__, dict) True Pickling -------- There's actually a substantial effort involved in making subclasses of `Persistent` work with plain-old pickle. The ZODB serialization layer never calls pickle on an object; it pickles the object's class description and its state as two separate pickles. >>> import pickle >>> p = P() >>> p.inc() >>> p2 = pickle.loads(pickle.dumps(p)) >>> p2.__class__ is P True >>> p2.x == p.x True We should also test that pickle works with custom getstate and setstate. Perhaps even reduce. The problem is that pickling depends on finding the class in a particular module, and classes defined here won't appear in any module. We could require each user of the tests to define a base class, but that might be tedious. Interfaces ---------- Some versions of Zope and ZODB have the `zope.interface` package available. If it is available, then persistent will be associated with several interfaces. It's hard to write a doctest test that runs the tests only if `zope.interface` is available, so this test looks a little unusual. One problem is that the assert statements won't do anything if you run with `-O`. >>> try: ... import zope.interface ... except ImportError: ... pass ... else: ... from persistent.interfaces import IPersistent ... assert IPersistent.implementedBy(Persistent) ... p = Persistent() ... assert IPersistent.providedBy(p) ... assert IPersistent.implementedBy(P) ... p = P() ... assert IPersistent.providedBy(p) zope2.13-2.13.21/source/ZODB3/src/persistent/tests/test_overriding_attrs.py0000644000175000017500000002530412214017464025414 0ustar arnauarnau############################################################################## # # Copyright (c) 2004 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

It is a simple challenge-response protocol that does not send passwords in the clear, but does not offer strong security. The RFC discusses many of the limitations of this kind of protocol. Guard the password database as if it contained plaintext passwords. It stores the hash of a username and password. This does not expose the plaintext password, but it is sensitive nonetheless. An attacker with the hash can impersonate the real user. This is a limitation of the simple digest scheme. HTTP is a stateless protocol, and ZEO is a stateful protocol. The security requirements are quite different as a result. The HTTP protocol uses a nonce as a challenge. The ZEO protocol requires a separate session key that is used for message authentication. We generate a second nonce for this purpose; the hash of nonce and user/realm/password is used as the session key. TODO: I'm not sure if this is a sound approach; SRP would be preferred.

This is typically invoked from the start.py script. Arguments (the first two are required and positional): addr -- the address at which the server should listen. This can be a tuple (host, port) to signify a TCP/IP connection or a pathname string to signify a Unix domain socket connection. A hostname may be a DNS name or a dotted IP address. storages -- a dictionary giving the storage(s) to handle. The keys are the storage names, the values are the storage instances, typically FileStorage or Berkeley storage instances. By convention, storage names are typically strings representing small integers starting at '1'. read_only -- an optional flag saying whether the server should operate in read-only mode. Defaults to false. Note that even if the server is operating in writable mode, individual storages may still be read-only. But if the server is in read-only mode, no write operations are allowed, even if the storages are writable. Note that pack() is considered a read-only operation. invalidation_queue_size -- The storage server keeps a queue of the objects modified by the last N transactions, where N == invalidation_queue_size. This queue is used to speed client cache verification when a client disconnects for a short period of time. invalidation_age -- If the invalidation queue isn't big enough to support a quick verification, but the last transaction seen by a client is younger than the invalidation age, then invalidations will be computed by iterating over transactions later than the given transaction. transaction_timeout -- The maximum amount of time to wait for a transaction to commit after acquiring the storage lock. If the transaction takes too long, the client connection will be closed and the transaction aborted. monitor_address -- The address at which the monitor server should listen. If specified, a monitor server is started. The monitor server provides server statistics in a simple text format. auth_protocol -- The name of the authentication protocol to use. Examples are "digest" and "srp". auth_database -- The name of the password database filename. It should be in a format compatible with the authentication protocol used; for instance, "sha" and "srp" require different formats. Note that to implement an authentication protocol, a server and client authentication mechanism must be implemented in a auth_* module, which should be stored inside the "auth" subdirectory.

It will report success if it updates to counter or if it gets a ConflictError. A ConflictError is considered a success, because the client was able to start a transaction.

Defaults to current time. -u UNIX_SOCKETS, --unix=UNIX_SOCKETS A unix-domain-socket server to connect to, of the form: path[:name] -h HOST Deprecated: Used with the -p and -S options, specified the host to connect to. -p PORT Deprecated: Used with the -h and -S options, specifies the port to connect to. -S NAME Deprecated: Used with the -h and -p, options, or with the -U option specified the storage name to use.

This is either a list of addresses or a single address. Each address can be a (hostname, port) tuple to signify a TCP/IP connection or a pathname string to signify a Unix domain socket connection. A hostname may be a DNS name or a dotted IP address. Required. storage The storage name, defaulting to '1'. The name must match one of the storage names supported by the server(s) specified by the addr argument. The storage name is displayed in the Zope control panel. cache_size The disk cache size, defaulting to 20 megabytes. This is passed to the ClientCache constructor. name The storage name, defaulting to ''. If this is false, str(addr) is used as the storage name. client A name used to construct persistent cache filenames. Defaults to None, in which case the cache is not persistent. See ClientCache for more info. var When client is not None, this specifies the directory where the persistent cache files are created. It defaults to None, in whichcase the current directory is used. min_disconnect_poll The minimum delay in seconds between attempts to connect to the server, in seconds. Defaults to 5 seconds. max_disconnect_poll The maximum delay in seconds between attempts to connect to the server, in seconds. Defaults to 300 seconds. wait_for_server_on_startup A backwards compatible alias for the wait argument. wait A flag indicating whether to wait until a connection with a server is made, defaulting to true. wait_timeout Maximum time to wait for a connection before giving up. Only meaningful if wait is True. read_only A flag indicating whether this should be a read-only storage, defaulting to false (i.e. writing is allowed by default). read_only_fallback A flag indicating whether a read-only remote storage should be acceptable as a fallback when no writable storages are available. Defaults to false. At most one of read_only and read_only_fallback should be true. username string with username to be used when authenticating. These only need to be provided if you are connecting to an authenticated server storage. password string with plaintext password to be used when authenticated. realm not documented. drop_cache_rather_verify a flag indicating that the cache should be dropped rather than expensively verified. blob_dir directory path for blob data. 'blob data' is data that is retrieved via the loadBlob API. shared_blob_dir Flag whether the blob_dir is a server-shared filesystem that should be used instead of transferring blob data over zrpc. blob_cache_size Maximum size of the ZEO blob cache, in bytes. If not set, then the cache size isn't checked and the blob directory will grow without bound. This option is ignored if shared_blob_dir is true. blob_cache_size_check ZEO check size as percent of blob_cache_size. The ZEO cache size will be checked when this many bytes have been loaded into the cache. Defaults to 10% of the blob cache size.

The address at which the server should listen. This can be in the form 'host:port' to signify a TCP/IP connection or a pathname string to signify a Unix domain socket connection (at least one '/' is required). A hostname may be a DNS name or a dotted IP address. If the hostname is omitted, the platform's default behavior is used when binding the listening socket ('' is passed to socket.bind() as the hostname portion of the address). Flag indicating whether the server should operate in read-only mode. Defaults to false. Note that even if the server is operating in writable mode, individual storages may still be read-only. But if the server is in read-only mode, no write operations are allowed, even if the storages are writable. Note that pack() is considered a read-only operation. The storage server keeps a queue of the objects modified by the last N transactions, where N == invalidation_queue_size. This queue is used to speed client cache verification when a client disconnects for a short period of time. The maximum age of a client for which quick-verification invalidations will be provided by iterating over the served storage. This option should only be used if the served storage supports efficient iteration from a starting point near the end of the transaction history (e.g. end of file). The address at which the monitor server should listen. If specified, a monitor server is started. The monitor server provides server statistics in a simple text format. This can be in the form 'host:port' to signify a TCP/IP connection or a pathname string to signify a Unix domain socket connection (at least one '/' is required). A hostname may be a DNS name or a dotted IP address. If the hostname is omitted, the platform's default behavior is used when binding the listening socket ('' is passed to socket.bind() as the hostname portion of the address). The maximum amount of time to wait for a transaction to commit after acquiring the storage lock, specified in seconds. If the transaction takes too long, the client connection will be closed and the transaction aborted. The name of the protocol used for authentication. The only protocol provided with ZEO is "digest," but extensions may provide other protocols. The path of the database containing authentication credentials. The authentication realm of the server. Some authentication schemes use a realm to identify the logical set of usernames that are accepted by this server. The full path to the file in which to write the ZEO server's Process ID at startup. If omitted, $INSTANCE/var/ZEO.pid is used. $INSTANCE/var/ZEO.pid (or $clienthome/ZEO.pid) indicates that the cache should be dropped rather than verified when the verification optimization is not available (e.g. when the ZEO server restarted). zope2.13-2.13.21/source/ZODB3/src/ZEO/zrpc/0000755000175000017500000000000012214017464016463 5ustar arnauarnauzope2.13-2.13.21/source/ZODB3/src/ZEO/zrpc/marshal.py0000644000175000017500000000716112214017464020471 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

In that # version, both the client and the server immediately send out # their protocol handshake when a connection is established, # without waiting for their peer, and disconnect when a different # handshake is receive. # # The new protocol uses this to enable new clients to talk to # 2.0.0 servers. In the new protocol: # # The server sends its protocol handshake to the client at once. # # The client waits until it receives the server's protocol handshake # before sending its own handshake. The client sends the lower of its # own protocol version and the server protocol version, allowing it to # talk to servers using later protocol versions (2.0.2 and higher) as # well: the effective protocol used will be the lower of the client # and server protocol. However, this changed in ZODB 3.3.1 (and # should have changed in ZODB 3.3) because an older server doesn't # support MVCC methods required by 3.3 clients. # # [Ugly details: In order to treat the first received message (protocol # handshake) differently than all later messages, both client and server # start by patching their message_input() method to refer to their # recv_handshake() method instead. In addition, the client has to arrange # to queue (delay) outgoing messages until it receives the server's # handshake, so that the first message the client sends to the server is # the client's handshake. This multiply-special treatment of the first # message is delicate, and several asyncore and thread subtleties were # handled unsafely before ZODB 3.2.6. # ] # # The ZEO modules ClientStorage and ServerStub have backwards # compatibility code for dealing with the previous version of the # protocol. The client accepts the old version of some messages, # and will not send new messages when talking to an old server. # # As long as the client hasn't sent its handshake, it can't send # anything else; output messages are queued during this time. # (Output can happen because the connection testing machinery can # start sending requests before the handshake is received.) # # UPGRADING FROM ZEO 2.0.0 TO NEWER VERSIONS: # # Because a new client can talk to an old server, but not vice # versa, all clients should be upgraded before upgrading any # servers. Protocol upgrades beyond 2.0.1 will not have this # restriction, because clients using protocol 2.0.1 or later can # talk to both older and newer servers. # # No compatibility with protocol version 1 is provided. # Connection is abstract (it must be derived from). ManagedServerConnection # and ManagedClientConnection are the concrete subclasses. They need to # supply a handshake() method appropriate for their role in protocol # negotiation. class Connection(smac.SizedMessageAsyncConnection, object): """Dispatcher for RPC on object on both sides of socket. The connection supports synchronous calls, which expect a return, and asynchronous calls, which do not. It uses the Marshaller class to handle encoding and decoding of method calls and arguments. Marshaller uses pickle to encode arbitrary Python objects. The code here doesn't ever see the wire format. A Connection is designed for use in a multithreaded application, where a synchronous call must block until a response is ready. A socket connection between a client and a server allows either side to invoke methods on the other side. The processes on each end of the socket use a Connection object to manage communication. The Connection deals with decoded RPC messages. They are represented as four-tuples containing: msgid, flags, method name, and a tuple of method arguments. The msgid starts at zero and is incremented by one each time a method call message is sent. Each side of the connection has a separate msgid state. When one side of the connection (the client) calls a method, it sends a message with a new msgid. The other side (the server), replies with a message that has the same msgid, the string ".reply" (the global variable REPLY) as the method name, and the actual return value in the args position. Note that each side of the Connection can initiate a call, in which case it will be the client for that particular call. The protocol also supports asynchronous calls. The client does not wait for a return value for an asynchronous call. If a method call raises an Exception, the exception is propagated back to the client via the REPLY message. The client side will raise any exception it receives instead of returning the value to the caller.

The client shares a common blob directory with the server. non-shared Blob data are loaded from the storage server and cached locally. A maximum size for the blob data can be set and data are removed when the size is exceeded. In this test, we'll demonstrate that blobs data are removed from a ZEO cache when the amount of data stored exceeds a given limit. Let's start by setting up some data: >>> addr, _ = start_server(blob_dir='server-blobs') We'll also create a client. >>> import ZEO >>> db = ZEO.DB(addr, blob_dir='blobs', blob_cache_size=3000) Here, we passed a blob_cache_size parameter, which specifies a target blob cache size. This is not a hard limit, but rather a target. It defaults to a very large value. We also passed a blob_cache_size_check option. The blob_cache_size_check option specifies the number of bytes, as a percent of the target that can be written or downloaded from the server before the cache size is checked. The blob_cache_size_check option defaults to 100. We passed 10, to check after writing 10% of the target size. ..

It does this in one of 2 ways: quick verification It gets a list of invalidations from the server since the last transaction the client has seen and applies those to it's disk and in-memory caches. This is only possible if there haven't been too many transactions since the client was last connected. full verification If quick verification isn't possible, the client iterates through it's disk cache asking the server to verify whether each current entry is valid. Unfortunately, for large caches, full verification is soooooo not quick that it is impractical. Quick verificatioin is highly desireable. To support quick verification, the server keeps a list of recent invalidations. The size of this list is controlled by the invalidation_queue_size parameter. If there is a lot of database activity, the size might need to be quite large to support having clients be disconnected for more than a few minutes. A very large invalidation queue size can use a lot of memory. To suppliment the invalidation queue, you can also specify an invalidation_age parameter. When a client connects and presents the last transaction id it has seen, we first check to see if the invalidation queue has that transaction id. It it does, then we send all transactions since that id. Otherwise, we check to see if the difference between storage's last transaction id and the given id is less than or equal to the invalidation age. If it is, then we iterate over the storage, starting with the given id, to get the invalidations since the given id. NOTE: This assumes that iterating from a point near the "end" of a database is inexpensive. Don't use this option for a storage for which that is not the case. Here's an example. We set up a server, using an invalidation-queue-size of 5: >>> addr, admin = start_server(zeo_conf=dict(invalidation_queue_size=5), ... keep=True) Now, we'll open a client with a persistent cache, set up some data, and then close client: >>> import ZEO, transaction >>> db = ZEO.DB(addr, client='test') >>> conn = db.open() >>> for i in range(9): ... conn.root()[i] = conn.root().__class__() ... conn.root()[i].x = 0 >>> transaction.commit() >>> db.close() We'll open another client, and commit some transactions: >>> db = ZEO.DB(addr) >>> conn = db.open() >>> import transaction >>> for i in range(2): ... conn.root()[i].x = 1 ... transaction.commit() >>> db.close() If we reopen the first client, we'll do quick verification. We'll turn on logging so we can see this: >>> import logging, sys >>> old_logging_level = logging.getLogger().getEffectiveLevel() >>> logging.getLogger().setLevel(logging.INFO) >>> handler = logging.StreamHandler(sys.stdout) >>> logging.getLogger().addHandler(handler) >>> db = ZEO.DB(addr, client='test') # doctest: +ELLIPSIS ('localhost', ... ('localhost', ...) Recovering 2 invalidations >>> logging.getLogger().removeHandler(handler) >>> [v.x for v in db.open().root().values()] [1, 1, 0, 0, 0, 0, 0, 0, 0] Now, if we disconnect and commit more than 5 transactions, we'll see that verification is necessary: >>> db.close() >>> db = ZEO.DB(addr) >>> conn = db.open() >>> import transaction >>> for i in range(9): ... conn.root()[i].x = 2 ... transaction.commit() >>> db.close() >>> logging.getLogger().addHandler(handler) >>> db = ZEO.DB(addr, client='test') # doctest: +ELLIPSIS ('localhost', ...

If a client has beed disconnected for too long, cache verification might be necessary, but cache verification can be very hard on the storage server. When verification is needed, a ZEO.interfaces.StaleCache event is published. Applications may handle this event to perform actions such as exiting the process to avoid a cold restart. ClientStorage provides an option to drop it's cache rather than doing verification. When this option is used, and verification would be necessary, after publishing the event, ClientStorage: - Invalidates all object caches - Drops or clears it's client cache. (The end result is that the cache is working but empty.) - Logs a CRITICAL message. Here's an example that shows that this is actually what happens. Start a server, create a cient to it and commit some data >>> addr, admin = start_server(keep=1) >>> import ZEO, transaction >>> db = ZEO.DB(addr, drop_cache_rather_verify=True, client='cache', ... name='test') >>> wait_connected(db.storage) >>> conn = db.open() >>> conn.root()[1] = conn.root().__class__() >>> conn.root()[1].x = 1 >>> transaction.commit() >>> len(db.storage._cache) 3 Now, we'll stop the server and restart with a different address: >>> stop_server(admin) >>> addr2, admin = start_server(keep=1) And create another client and write some data to it: >>> db2 = ZEO.DB(addr2) >>> wait_connected(db2.storage) >>> conn2 = db2.open() >>> for i in range(5): ... conn2.root()[1].x += 1 ... transaction.commit() >>> db2.close() >>> stop_server(admin) Now, we'll restart the server. Before we do that, we'll capture logging and event data: >>> import logging, zope.testing.loggingsupport, zope.event >>> handler = zope.testing.loggingsupport.InstalledHandler( ... 'ZEO.ClientStorage', level=logging.ERROR) >>> events = [] >>> def event_handler(e): ... events.append(( ... len(e.storage._cache), str(handler), e.__class__.__name__)) >>> zope.event.subscribers.append(event_handler) Note that the event handler is saving away the length of the cache and the state of the log handler. We'll use this to show that the event is generated before the cache is dropped or the message is logged. Now, we'll restart the server on the original address: >>> _, admin = start_server(zeo_conf=dict(invalidation_queue_size=1), ... addr=addr, keep=1) >>> wait_connected(db.storage) Now, let's verify our assertions above: - Publishes a stale-cache event. >>> for e in events: ... print e (3, '', 'StaleCache') Note that the length of the cache when the event handler was called waa non-zero. This is because the cache wasn't cleared yet. Similarly, the dropping-cache message hasn't been logged yet. >>> del events[:] - Drops or clears it's client cache. (The end result is that the cache is working but empty.) >>> len(db.storage._cache) 0 - Invalidates all object caches >>> transaction.abort() >>> conn.root()._p_changed - Logs a CRITICAL message. >>> print handler ZEO.ClientStorage CRITICAL test dropping stale cache >>> handler.clear() If we access the root object, it'll be loaded from the server: >>> conn.root()[1].x 6 >>> len(db.storage._cache) 2 Similarly, if we simply disconnect the client, and write data from another client: >>> db.close() >>> db2 = ZEO.DB(addr) >>> wait_connected(db2.storage) >>> conn2 = db2.open() >>> for i in range(5): ... conn2.root()[1].x += 1 ... transaction.commit() >>> db2.close() >>> db = ZEO.DB(addr, drop_cache_rather_verify=True, client='cache', ... name='test') >>> wait_connected(db.storage) - Drops or clears it's client cache. (The end result is that the cache is working but empty.) >>> len(db.storage._cache) 1 (When a database is created, it checks to make sure the root object is in the database, which is why we get 1, rather than 0 objects in the cache.) - Publishes a stake-cache event. >>> for e in events: ... print e (2, '', 'StaleCache') >>> del events[:] - Logs a CRITICAL message. >>> print handler ZEO.ClientStorage CRITICAL test dropping stale cache >>> handler.clear() If we access the root object, it'll be loaded from the server: >>> conn = db.open() >>> conn.root()[1].x 11 Finally, let's look at what happens without the drop_cache_rather_verify option: >>> db.close() >>> db = ZEO.DB(addr, client='cache') >>> wait_connected(db.storage) >>> conn = db.open() >>> conn.root()[1].x 11 >>> conn.root()[2] = conn.root().__class__() >>> transaction.commit() >>> len(db.storage._cache) 4 >>> stop_server(admin) >>> addr2, admin = start_server(keep=1) >>> db2 = ZEO.DB(addr2) >>> wait_connected(db2.storage) >>> conn2 = db2.open() >>> for i in range(5): ... conn2.root()[1].x += 1 ... transaction.commit() >>> db2.close() >>> stop_server(admin) >>> _, admin = start_server(zeo_conf=dict(invalidation_queue_size=1), ... addr=addr) >>> wait_connected(db.storage) >>> for e in events: ... print e (4, '', 'StaleCache') >>> print handler >>> len(db.storage._cache) 3 Here we see the cache wasn't dropped, although one of the records was invalidated during verification. ..

Among other things, this allows client storages to be used in storage servers, allowing storage-server fan out, spreading read load over multiple storage servers.

We'll subclass it and give it a do-nothing dispatcher "class": >>> import ZEO.StorageServer >>> class StorageServer(ZEO.StorageServer.StorageServer): ... DispatcherClass = lambda *a, **k: None We'll create a storage instance and a storage server using it: >>> storage = FauxStorage() >>> server = StorageServer('addr', dict(t=storage)) Our storage now has a db attribute that provides IStorageDB. It's references method is just the referencesf function from ZODB.Serialize >>> import ZODB.serialize >>> storage.db.references is ZODB.serialize.referencesf True To see the effects of the invalidation messages, we'll create a client stub that implements the client invalidation calls: >>> class Client: ... def __init__(self, name): ... self.name = name ... def invalidateTransaction(self, tid, invalidated): ... print 'invalidateTransaction', tid, self.name ... print invalidated >>> class Connection: ... def __init__(self, mgr, obj): ... self.mgr = mgr ... self.obj = obj ... def should_close(self): ... print 'closed', self.obj.name ... self.mgr.close_conn(self) ... def poll(self): ... pass ... ... @property ... def trigger(self): ... return self ... ... def pull_trigger(self): ... pass >>> class ZEOStorage: ... def __init__(self, server, name): ... self.name = name ... self.connection = Connection(server, self) ... self.client = Client(name) Now, we'll register the client with the storage server: >>> _ = server.register_connection('t', ZEOStorage(server, 1)) >>> _ = server.register_connection('t', ZEOStorage(server, 2)) Now, if we call invalidate, we'll see it propigate to the client: >>> storage.db.invalidate('trans2', ['ob1', 'ob2']) invalidateTransaction trans2 1 ['ob1', 'ob2'] invalidateTransaction trans2 2 ['ob1', 'ob2'] >>> storage.db.invalidate('trans3', ['ob1', 'ob2']) invalidateTransaction trans3 1 ['ob1', 'ob2'] invalidateTransaction trans3 2 ['ob1', 'ob2'] The storage servers queue will reflect the invalidations: >>> for tid, invalidated in server.invq['t']: ... print repr(tid), invalidated 'trans3' ['ob1', 'ob2'] 'trans2' ['ob1', 'ob2'] 'trans1' ['ob0', 'ob1'] 'trans0' ['ob0'] If we call invalidateCache, the storage server will close each of it's connections: >>> storage.db.invalidateCache() closed 1 closed 2 The connections will then reopen and revalidate their caches. The servers's invalidation queue will get reset >>> for tid, invalidated in server.invq['t']: ... print repr(tid), invalidated 'trans1' ['ob0', 'ob1'] 'trans0' ['ob0'] zope2.13-2.13.21/source/ZODB3/src/ZEO/tests/servertesting.py0000644000175000017500000000511312214017464022125 0ustar arnauarnau############################################################################## # # Copyright Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

It assumes that the optional authentication protocol isn't used. At the lowest level, the protocol consists of sized messages. All communication between the client and server consists of sized messages. A sized message consists of a 4-byte unsigned big-endian content length, followed by the content. There are two subprotocols, for protocol negotiation, and for normal operation. The normal operation protocol is a basic RPC protocol. In the protocol negotiation phase, the server sends a protocol identifier to the client. The client chooses a protocol to use to the server. The client or the server can fail if it doesn't like the protocol string sent by the other party. After sending their protocol strings, the client and server switch to RPC mode. The RPC protocol uses messages that are pickled tuples consisting of: message_id The message id is used to match replies with requests, allowing multiple outstanding synchronous requests. async_flag An integer 0 for a regular (2-way) request and 1 for a one-way request. Two-way requests have a reply. One way requests don't. ZRS tries to use as many one-way requests as possible to avoid network round trips. name The name of a method to call. If this is the special string ".reply", then the message is interpreted as a return from a synchronous call. args A tuple of positional arguments or returned values. After making a connection and negotiating the protocol, the following interactions occur: - The client requests the authentication protocol by calling getAuthProtocol. For this discussion, we'll assume the server returns None. Note that if the server doesn't require authentication, this step is optional. - The client calls register passing a storage identifier and a read-only flag. The server doesn't return a value, but it may raise an exception either if the storage doesn't exist, or if the storage is readonly and the read-only flag passed by the client is false. At this point, the client and server send each other messages as needed. The client may make regular or one-way calls to the server. The server sends replies and one-way calls to the client. zope2.13-2.13.21/source/ZODB3/src/ZEO/cache.py0000644000175000017500000007234612214017464017136 0ustar arnauarnau############################################################################## # # Copyright (c) 2003 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

Macros ====== `BTrees` are defined using a "template", roughly akin to a C++ template. To create a new family of `BTrees`, create a source file that defines macros used to handle differences in key and value types: Configuration Macros -------------------- ``MASTER_ID`` A string to hold an RCS/CVS Id key to be included in compiled binaries. ``MOD_NAME_PREFIX`` A string (like "IO" or "OO") that provides the prefix used for the module. This gets used to generate type names and the internal module name string. ``DEFAULT_MAX_BUCKET_SIZE`` An int giving the maximum bucket size (number of key/value pairs). When a bucket gets larger than this due to an insertion *into a BTREE*, it splits. Inserting into a bucket directly doesn't split, and functions that produce a bucket output (e.g., ``union()``) also have no bound on how large a bucket may get. Someday this will be tunable on `BTree`. instances. ``DEFAULT_MAX_BTREE_SIZE`` An ``int`` giving the maximum size (number of children) of an internal btree node. Someday this will be tunable on ``BTree`` instances. Macros for Keys --------------- ``KEY_TYPE`` The C type declaration for keys (e.g., ``int`` or ``PyObject*``). ``KEY_TYPE_IS_PYOBJECT`` Define if ``KEY_TYPE`` is a ``PyObject*`, else ``undef``. ``KEY_CHECK(K)`` Tests whether the ``PyObject* K`` can be converted to the (``C``) key type (``KEY_TYPE``). The macro should return a boolean (zero for false, non-zero for true). When it returns false, its caller should probably set a ``TypeError`` exception. ``TEST_KEY_SET_OR(V, K, T)`` Like Python's ``cmp()``. Compares K(ey) to T(arget), where ``K`` and ``T`` are ``C`` values of type `KEY_TYPE`. ``V`` is assigned an `int` value depending on the outcome:: < 0 if K < T == 0 if K == T > 0 if K > T This macro acts like an ``if``, where the following statement is executed only if a Python exception has been raised because the values could not be compared. ``DECREF_KEY(K)`` ``K`` is a value of ``KEY_TYPE``. If ``KEY_TYPE`` is a flavor of ``PyObject*``, write this to do ``Py_DECREF(K)``. Else (e.g., ``KEY_TYPE`` is ``int``) make it a nop. ``INCREF_KEY(K)`` ``K`` is a value of `KEY_TYPE`. If `KEY_TYPE` is a flavor of ``PyObject*``, write this to do ``Py_INCREF(K)``. Else (e.g., `KEY_TYPE` is ``int``) make it a nop. ``COPY_KEY(K, E)`` Like ``K=E``. Copy a key from ``E`` to ``K``, both of ``KEY_TYPE``. Note that this doesn't ``decref K`` or ``incref E`` when ``KEY_TYPE`` is a ``PyObject*``; the caller is responsible for keeping refcounts straight. ``COPY_KEY_TO_OBJECT(O, K)`` Roughly like ``O=K``. ``O`` is a ``PyObject*``, and the macro must build a Python object form of ``K``, assign it to ``O``, and ensure that ``O`` owns the reference to its new value. It may do this by creating a new Python object based on ``K`` (e.g., ``PyInt_FromLong(K)`` when ``KEY_TYPE`` is ``int``), or simply by doing ``Py_INCREF(K)`` if ``KEY_TYPE`` is a ``PyObject*``. ``COPY_KEY_FROM_ARG(TARGET, ARG, STATUS)`` Copy an argument to the target without creating a new reference to ``ARG``. ``ARG`` is a ``PyObject*``, and ``TARGET`` is of type ``KEY_TYPE``. If this can't be done (for example, ``KEY_CHECK(ARG)`` returns false), set a Python error and set status to ``0``. If there is no error, leave status alone. Macros for Values ----------------- ``VALUE_TYPE`` The C type declaration for values (e.g., ``int`` or ``PyObject*``). ``VALUE_TYPE_IS_PYOBJECT`` Define if ``VALUE_TYPE`` is a ``PyObject*``, else ``undef``. ``TEST_VALUE(X, Y)`` Like Python's ``cmp()``. Compares ``X`` to ``Y``, where ``X`` & ``Y`` are ``C`` values of type ``VALUE_TYPE``. The macro returns an ``int``, with value:: < 0 if X < Y == 0 if X == Y > 0 if X > Y Bug: There is no provision for determining whether the comparison attempt failed (set a Python exception). ``DECREF_VALUE(K)`` Like ``DECREF_KEY``, except applied to values of ``VALUE_TYPE``. ``INCREF_VALUE(K)`` Like ``INCREF_KEY``, except applied to values of ``VALUE_TYPE``. ``COPY_VALUE(K, E)`` Like ``COPY_KEY``, except applied to values of ``VALUE_TYPE``. ``COPY_VALUE_TO_OBJECT(O, K)`` Like ``COPY_KEY_TO_OBJECT``, except applied to values of ``VALUE_TYPE``. ``COPY_VALUE_FROM_ARG(TARGET, ARG, STATUS)`` Like ``COPY_KEY_FROM_ARG``, except applied to values of ``VALUE_TYPE``. ``NORMALIZE_VALUE(V, MIN)`` Normalize the value, ``V``, using the parameter ``MIN``. This is almost certainly a YAGNI. It is a no-op for most types. For integers, ``V`` is replaced by ``V/MIN`` only if ``MIN > 0``. Macros for Set Operations ------------------------- ``MERGE_DEFAULT`` A value of ``VALUE_TYPE`` specifying the value to associate with set elements when sets are merged with mappings via weighed union or weighted intersection. ``MERGE(O1, w1, O2, w2)`` Performs a weighted merge of two values, ``O1`` and ``O2``, using weights ``w1`` and ``w2``. The result must be of ``VALUE_TYPE``. Note that weighted unions and weighted intersections are not enabled if this macro is left undefined. ``MERGE_WEIGHT(O, w)`` Computes a weighted value for ``O``. The result must be of ``VALUE_TYPE``. This is used for "filling out" weighted unions, i.e. to compute a weighted value for keys that appear in only one of the input mappings. If left undefined, ``MERGE_WEIGHT`` defaults to:: #define MERGE_WEIGHT(O, w) (O) ``MULTI_INT_UNION`` The value doesn't matter. If defined, `SetOpTemplate.c` compiles code for a ``multiunion()`` function (compute a union of many input sets at high speed). This currently makes sense only for structures with integer keys. BTree Clues =========== More or less random bits of helpful info. + In papers and textbooks, this flavor of BTree is usually called a B+-Tree, where "+" is a superscript. + All keys and all values live in the bucket leaf nodes. Keys in interior (BTree) nodes merely serve to guide a search efficiently toward the correct leaf. + When a key is deleted, it's physically removed from the bucket it's in, but this doesn't propagate back up the tree: since keys in interior nodes only serve to guide searches, it's OK-- and saves time --to leave "stale" keys in interior nodes. + No attempt is made to rebalance the tree after a deletion, unless a bucket thereby becomes entirely empty. "Classic BTrees" do rebalance, keeping all buckets at least half full (provided there are enough keys in the entire tree to fill half a bucket). The tradeoffs are murky. Pathological cases in the presence of deletion do exist. Pathologies include trees tending toward only one key per bucket, and buckets at differing depths (all buckets are at the same depth in a classic BTree). + ``DEFAULT_MAX_BUCKET_SIZE`` and ``DEFAULT_MAX_BTREE_SIZE`` are chosen mostly to "even out" pickle sizes in storage. That's why, e.g., an `IIBTree` has larger values than an `OOBTree`: pickles store ints more efficiently than they can store arbitrary Python objects. + In a non-empty BTree, every bucket node contains at least one key, and every BTree node contains at least one child and a non-NULL firstbucket pointer. However, a BTree node may not contain any keys. + An empty BTree consists solely of a BTree node with ``len==0`` and ``firstbucket==NULL``. + Although a BTree can become unbalanced under a mix of inserts and deletes (meaning both that there's nothing stronger that can be said about buckets than that they're not empty, and that buckets can appear at different depths), a BTree node always has children of the same kind: they're all buckets, or they're all BTree nodes. The ``BTREE_SEARCH`` Macro ========================== For notational ease, consider a fixed BTree node ``x``, and let :: K(i) mean x->data.key[i] C(i) mean all the keys reachable from x->data.child[i] For each ``i`` in ``0`` to ``x->len-1`` inclusive, :: K(i) <= C(i) < K(i+1) is a BTree node invariant, where we pretend that ``K(0)`` holds a key smaller than any possible key, and ``K(x->len)`` holds a key larger than any possible key. (Note that ``K(x->len)`` doesn't actually exist, and ``K(0)`` is never used although space for it exists in non-empty BTree nodes.) When searching for a key ``k``, then, the child pointer we want to follow is the one at index ``i`` such that ``K(i) <= k < K(i+1)``. There can be at most one such ``i``, since the ``K(i)`` are strictly increasing. And there is at least one such ``i`` provided the tree isn't empty (so that ``0 < len``). For the moment, assume the tree isn't empty (we'll get back to that later). The macro's chief loop invariant is :: K(lo) < k < K(hi) This holds trivially at the start, since ``lo`` is set to ``0``, and ``hi`` to ``x->len``, and we pretend ``K(0)`` is minus infinity and ``K(len)`` is plus infinity. Inside the loop, if ``K(i) < k`` we set ``lo`` to ``i``, and if ``K(i) > k`` we set ``hi`` to ``i``. These obviously preserve the invariant. If ``K(i) == k``, the loop breaks and sets the result to ``i``, and since ``K(i) == k`` in that case ``i`` is obviously the correct result. Other cases depend on how ``i = floor((lo + hi)/2)`` works, exactly. Suppose ``lo + d = hi`` for some ``d >= 0``. Then ``i = floor((lo + lo + d)/2) = floor(lo + d/2) = lo + floor(d/2)``. So: a. ``[d == 0] (lo == i == hi)`` if and only if ``(lo == hi)``. b. ``[d == 1] (lo == i < hi)`` if and only if ``(lo+1 == hi)``. c. ``[d > 1] (lo < i < hi)`` if and only if ``(lo+1 < hi)``. If the node is empty ``(x->len == 0)``, then ``lo==i==hi==0`` at the start, and the loop exits immediately (the first ``i > lo`` test fails), without entering the body. Else ``lo < hi`` at the start, and the invariant ``K(lo) < k < K(hi)`` holds. If ``lo+1 < hi``, we're in case (c): ``i`` is strictly between ``lo`` and ``hi``, so the loop body is entered, and regardless of whether the body sets the new ``lo`` or the new ``hi`` to ``i``, the new ``lo`` is strictly less than the new ``hi``, and the difference between the new ``lo`` and new ``hi`` is strictly less than the difference between the old ``lo`` and old ``hi``. So long as the new ``lo + 1`` remains < the new ``hi``, we stay in this case. We can't stay in this case forever, though: because ``hi-lo`` decreases on each trip but remains > ``0``, ``lo+1 == hi`` must eventually become true. (In fact, it becomes true quickly, in about ``log2(x->len)`` trips; the point is more that ``lo`` doesn't equal ``hi`` when the loop ends, it has to end with ``lo+1==hi`` and ``i==lo``). Then we're in case (b): ``i==lo==hi-1`` then, and the loop exits. The invariant still holds, with ``lo==i`` and ``hi==lo+1==i+1``:: K(i) < k < K(i+1) so ``i`` is again the correct answer. Optimization points: -------------------- + Division by 2 is done via shift rather via "/2". These are signed ints, and almost all C compilers treat signed int division as truncating, and shifting is not the same as truncation for signed int division. The compiler has no way to know these values aren't negative, so has to generate longer-winded code for "/2". But we know these values aren't negative, and exploit it. + The order of _cmp comparisons matters. We're in an interior BTree node, and are looking at only a tiny fraction of all the keys that exist. So finding the key exactly in this node is unlikely, and checking ``_cmp == 0`` is a waste of time to the same extent. It doesn't matter whether we check for ``_cmp < 0`` or ``_cmp > 0`` first, so long as we do both before worrying about equality. + At the start of a routine, it's better to run this macro even if ``x->len`` is ``0`` (check for that afterwards). We just called a function and so probably drained the pipeline. If the first thing we do then is read up ``self->len`` and check it against ``0``, we just sit there waiting for the data to get read up, and then another immediate test-and-branch, and for a very unlikely case (BTree nodes are rarely empty). It's better to get into the loop right away so the normal case makes progress ASAP. The ``BUCKET_SEARCH`` Macro =========================== This has a different job than ``BTREE_SEARCH``: the key ``0`` slot is legitimate in a bucket, and we want to find the index at which the key belongs. If the key is larger than the bucket's largest key, a new slot at index len is where it belongs, else it belongs at the smallest ``i`` with ``keys[i]`` >= the key we're looking for. We also need to know whether or not the key is present (``BTREE_SEARCH`` didn't care; it only wanted to find the next node to search). The mechanics of the search are quite similar, though. The primary loop invariant changes to (say we're searching for key ``k``):: K(lo-1) < k < K(hi) where ``K(i)`` means ``keys[i]``, and we pretend ``K(-1)`` is minus infinity and ``K(len)`` is plus infinity. If the bucket is empty, ``lo=hi=i=0`` at the start, the loop body is never entered, and the macro sets ``INDEX`` to 0 and ``ABSENT`` to true. That's why ``_cmp`` is initialized to 1 (``_cmp`` becomes ``ABSENT``). Else the bucket is not empty, lok``, ``hi`` is set to ``i``, preserving that ``K[hi] = K[i] > k``. If the loop exits after either of those, ``_cmp != 0``, so ``ABSENT`` becomes true. If ``K[i]=k``, the loop breaks, so that ``INDEX`` becomes ``i``, and ``ABSENT`` becomes false (``_cmp=0`` in this case). The same case analysis for ``BTREE_SEARCH`` on ``lo`` and ``hi`` holds here: a. ``(lo == i == hi)`` if and only if ``(lo == hi)``. b. ``(lo == i < hi)`` if and only if ``(lo+1 == hi)``. c. ``(lo < i < hi)`` if and only if ``(lo+1 < hi)``. So long as ``lo+1 < hi``, we're in case (c), and either break with equality (in which case the right results are obviously computed) or narrow the range. If equality doesn't obtain, the range eventually narrows to cases (a) or (b). To go from (c) to (a), we must have ``lo+2==hi`` at the start, and ``K[i]=K[lo+1] key``), because when it pays it narrows the range more (we get a little boost from setting ``lo=i+1`` in this case; the other case sets ``hi=i``, which isn't as much of a narrowing). zope2.13-2.13.21/source/ZODB3/src/BTrees/BucketTemplate.c0000644000175000017500000013703312214017464021320 0ustar arnauarnau/***************************************************************************** Copyright (c) 2001, 2002 Zope Foundation and Contributors.

Return: -1 Error; offset and bucket unchanged 0 Not found; offset and bucket unchanged 1 Correct bucket and offset stored; the caller owns a new reference to the bucket. Internal: We do binary searches in BTree nodes downward, at each step following C(i) where K(i) <= key < K(i+1). As always, K(i) <= C(i) < K(i+1) too. (See Maintainer.txt for the meaning of that notation.) That eventually leads to a bucket where we do Bucket_findRangeEnd. That usually works, but there are two cases where it can fail to find the correct answer: 1. On a low search, we find a bucket with keys >= K(i), but that doesn't imply there are keys in the bucket >= key. For example, suppose a bucket has keys in 1..100, its successor's keys are in 200..300, and we're doing a low search on 150. We'll end up in the first bucket, but there are no keys >= 150 in it. K(i+1) > key, though, and all the keys in C(i+1) >= K(i+1) > key, so the first key in the next bucket (if any) is the correct result. This is easy to find by following the bucket 'next' pointer. 2. On a high search, again that the keys in the bucket are >= K(i) doesn't imply that any key in the bucket is <= key, but it's harder for this to fail (and an earlier version of this routine didn't catch it): if K(i) itself is in the bucket, it works (then K(i) <= key is *a* key in the bucket that's in the desired range). But when keys get deleted from buckets, they aren't also deleted from BTree nodes, so there's no guarantee that K(i) is in the bucket. For example, delete the smallest key S from some bucket, and S remains in the interior BTree nodes. Do a high search for S, and the BTree nodes direct the search to the bucket S used to be in, but all keys remaining in that bucket are > S. The largest key in the *preceding* bucket (if any) is < K(i), though, and K(i) <= key, so the largest key in the preceding bucket is < key and so is the proper result. This is harder to get at efficiently, as buckets are linked only in the increasing direction. While we're searching downward, deepest_smaller is set to the node deepest in the tree where we *could* have gone to the left of C(i). The rightmost bucket in deepest_smaller's subtree is the bucket preceding the bucket we find at first. This is clumsy to get at, but efficient. */ static int BTree_findRangeEnd(BTree *self, PyObject *keyarg, int low, int exclude_equal, Bucket **bucket, int *offset) { Sized *deepest_smaller = NULL; /* last possibility to move left */ int deepest_smaller_is_btree = 0; /* Boolean; if false, it's a bucket */ Bucket *pbucket; int self_got_rebound = 0; /* Boolean; when true, deactivate self */ int result = -1; /* Until proven innocent */ int i; KEY_TYPE key; int copied = 1; COPY_KEY_FROM_ARG(key, keyarg, copied); UNLESS (copied) return -1; /* We don't need to: PER_USE_OR_RETURN(self, -1); because the caller does. */ UNLESS (self->data && self->len) return 0; /* Search downward until hitting a bucket, stored in pbucket. */ for (;;) { Sized *pchild; int pchild_is_btree; BTREE_SEARCH(i, self, key, goto Done); pchild = self->data[i].child; pchild_is_btree = SameType_Check(self, pchild); if (i) { deepest_smaller = self->data[i-1].child; deepest_smaller_is_btree = pchild_is_btree; } if (pchild_is_btree) { if (self_got_rebound) { PER_UNUSE(self); } self = BTREE(pchild); self_got_rebound = 1; PER_USE_OR_RETURN(self, -1); } else { pbucket = BUCKET(pchild); break; } } /* Search the bucket for a suitable key. */ i = Bucket_findRangeEnd(pbucket, keyarg, low, exclude_equal, offset); if (i < 0) goto Done; if (i > 0) { Py_INCREF(pbucket); *bucket = pbucket; result = 1; goto Done; } /* This may be one of the two difficult cases detailed in the comments. */ if (low) { Bucket *next; UNLESS(PER_USE(pbucket)) goto Done; next = pbucket->next; if (next) { result = 1; Py_INCREF(next); *bucket = next; *offset = 0; } else result = 0; PER_UNUSE(pbucket); } /* High-end search: if it's possible to go left, do so. */ else if (deepest_smaller) { if (deepest_smaller_is_btree) { UNLESS(PER_USE(deepest_smaller)) goto Done; /* We own the reference this returns. */ pbucket = BTree_lastBucket(BTREE(deepest_smaller)); PER_UNUSE(deepest_smaller); if (pbucket == NULL) goto Done; /* error */ } else { pbucket = BUCKET(deepest_smaller); Py_INCREF(pbucket); } UNLESS(PER_USE(pbucket)) goto Done; result = 1; *bucket = pbucket; /* transfer ownership to caller */ *offset = pbucket->len - 1; PER_UNUSE(pbucket); } else result = 0; /* simply not found */ Done: if (self_got_rebound) { PER_UNUSE(self); } return result; } static PyObject * BTree_maxminKey(BTree *self, PyObject *args, int min) { PyObject *key=0; Bucket *bucket = NULL; int offset, rc; int empty_tree = 1; UNLESS (PyArg_ParseTuple(args, "|O", &key)) return NULL; UNLESS (PER_USE(self)) return NULL; UNLESS (self->data && self->len) goto empty; /* Find the range */ if (key) { if ((rc = BTree_findRangeEnd(self, key, min, 0, &bucket, &offset)) <= 0) { if (rc < 0) goto err; empty_tree = 0; goto empty; } PER_UNUSE(self); UNLESS (PER_USE(bucket)) { Py_DECREF(bucket); return NULL; } } else if (min) { bucket = self->firstbucket; PER_UNUSE(self); PER_USE_OR_RETURN(bucket, NULL); Py_INCREF(bucket); offset = 0; } else { bucket = BTree_lastBucket(self); PER_UNUSE(self); UNLESS (PER_USE(bucket)) { Py_DECREF(bucket); return NULL; } assert(bucket->len); offset = bucket->len - 1; } COPY_KEY_TO_OBJECT(key, bucket->keys[offset]); PER_UNUSE(bucket); Py_DECREF(bucket); return key; empty: PyErr_SetString(PyExc_ValueError, empty_tree ?

Over time, it may document more. 64-bit integers and strings --------------------------------- ZODB uses 64-bit transaction ids that are typically represented as strings, but are sometimes manipulated as integers. Object ids are strings too and it is common to ise 64-bit strings that are just packed integers. Functions p64 and u64 pack and unpack integers as strings: >>> ZODB.utils.p64(250347764455111456) '\x03yi\xf7"\xa8\xfb ' >>> print ZODB.utils.u64('\x03yi\xf7"\xa8\xfb ') 250347764455111456 The contant z64 has zero packed as a 64-bit string: >>> ZODB.utils.z64 '\x00\x00\x00\x00\x00\x00\x00\x00' Transaction id generation ------------------------- Storages assign transaction ids as transactions are committed. These are based on UTC time, but must be strictly increasing. The newTid function akes this pretty easy. To see this work (in a predictable way), we'll first hack time.time: >>> import time >>> old_time = time.time >>> time.time = lambda : 1224825068.12 Now, if we ask for a new time stamp, we'll get one based on our faux time: >>> tid = ZODB.utils.newTid(None) >>> tid '\x03yi\xf7"\xa54\x88' newTid requires an old tid as an argument. The old tid may be None, if we don't have a previous transaction id. This time is based on the current time, which we can see by converting it to a time stamp. >>> import ZODB.TimeStamp >>> print ZODB.TimeStamp.TimeStamp(tid) 2008-10-24 05:11:08.120000 To assure that we get a new tid that is later than the old, we can pass an existing tid. Let's pass the tid we just got. >>> tid2 = ZODB.utils.newTid(tid) >>> long(ZODB.utils.u64(tid)), long(ZODB.utils.u64(tid2)) (250347764454864008L, 250347764454864009L) Here, since we called it at the same time, we got a time stamp that was only slightly larger than the previos one. Of course, at a later time, the time stamp we get will be based on the time: >>> time.time = lambda : 1224825069.12 >>> tid = ZODB.utils.newTid(tid2) >>> print ZODB.TimeStamp.TimeStamp(tid) 2008-10-24 05:11:09.120000 >>> time.time = old_time Locking support --------------- Storages are required to be thread safe. The locking descriptor helps automate that. It arranges for a lock to be acquired when a function is called and released when a function exits. To demonstrate this, we'll create a "lock" type that simply prints when it is called: >>> class Lock: ... def acquire(self): ... print 'acquire' ... def release(self): ... print 'release' Now we'll demonstrate the descriptor: >>> class C: ... _lock = Lock() ... _lock_acquire = _lock.acquire ... _lock_release = _lock.release ... ... @ZODB.utils.locked ... def meth(self, *args, **kw): ... print 'meth', args, kw The descriptor expects the instance it wraps to have a '_lock attribute. >>> C().meth(1, 2, a=3) acquire meth (1, 2) {'a': 3} release .. Edge cases We can get the method from the class: >>> C.meth # doctest: +ELLIPSIS >>> C.meth(C()) acquire meth () {} release >>> class C2: ... _lock = Lock() ... _lock_acquire = _lock.acquire ... _lock_release = _lock.release >>> C.meth(C2()) # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... TypeError: unbound method meth() must be called with C instance as first argument (got C2 instance instead) Preconditions ------------- Often, we want to supply method preconditions. The locking descriptor supports optional method preconditions [1]_. >>> class C: ... def __init__(self): ... _lock = Lock() ... self._lock_acquire = _lock.acquire ... self._lock_release = _lock.release ... self._opened = True ... self._transaction = None ... ... def opened(self): ... """The object is open ... """ ... print 'checking if open' ... return self._opened ... ... def not_in_transaction(self): ... """The object is not in a transaction ... """ ... print 'checking if in a transaction' ... return self._transaction is None ... ... @ZODB.utils.locked(opened, not_in_transaction) ... def meth(self, *args, **kw): ... print 'meth', args, kw >>> c = C() >>> c.meth(1, 2, a=3) acquire checking if open checking if in a transaction meth (1, 2) {'a': 3} release >>> c._transaction = 1 >>> c.meth(1, 2, a=3) # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... AssertionError: ('Failed precondition: ', 'The object is not in a transaction') >>> c._opened = False >>> c.meth(1, 2, a=3) # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... AssertionError: ('Failed precondition: ', 'The object is open') .. [1] Arguably, preconditions should be handled via separate descriptors, but for ZODB storages, almost all methods need to be locked. Combining preconditions with locking provides both efficiency and concise expressions. A more general-purpose facility would almost certainly provide separate descriptors for preconditions. zope2.13-2.13.21/source/ZODB3/src/ZODB/POSException.py0000644000175000017500000002730012214017464020502 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

Subtransactions are nested to *one* level. There are top-level transactions and subtransactions. When a transaction is committed, a flag is passed indicating whether it is a subtransaction or a top-level transaction. Consider the following exampler commit calls: - ``commit()`` A regular top-level transaction is committed. - ``commit(1)`` A subtransaction is committed. There is now one subtransaction of the current top-level transaction. - ``commit(1)`` A subtransaction is committed. There are now two subtransactions of the current top-level transaction. - ``abort(1)`` A subtransaction is aborted. There are still two subtransactions of the current top-level transaction; work done since the last ``commit(1)`` call is discarded. - ``commit()`` We now commit a top-level transaction. The work done in the previous two subtransactions *plus* work done since the last ``abort(1)`` call is saved. - ``commit(1)`` A subtransaction is committed. There is now one subtransaction of the current top-level transaction. - ``commit(1)`` A subtransaction is committed. There are now two subtransactions of the current top-level transaction. - ``abort()`` We now abort a top-level transaction. We discard the work done in the previous two subtransactions *plus* work done since the last ``commit(1)`` call. zope2.13-2.13.21/source/ZODB3/src/ZODB/DemoStorage.test0000644000175000017500000002544412214017464020731 0ustar arnauarnau========================== DemoStorage demo (doctest) ========================== DemoStorages provide a way to provide incremental updates to an existing, base, storage without updating the storage. .. We need to mess with time to prevent spurious test failures on windows >>> now = 1231019584.0 >>> def faux_time_time(): ... global now ... now += .1 ... return now >>> import time >>> real_time_time = time.time >>> time.time = faux_time_time To see how this works, we'll start by creating a base storage and puting an object (in addition to the root object) in it: >>> from ZODB.FileStorage import FileStorage >>> base = FileStorage('base.fs') >>> from ZODB.DB import DB >>> db = DB(base) >>> from persistent.mapping import PersistentMapping >>> conn = db.open() >>> conn.root()['1'] = PersistentMapping({'a': 1, 'b':2}) >>> import transaction >>> transaction.commit() >>> db.close() >>> import os >>> original_size = os.path.getsize('base.fs') Now, lets reopen the base storage in read-only mode: >>> base = FileStorage('base.fs', read_only=True) And open a new storage to store changes: >>> changes = FileStorage('changes.fs') and combine the 2 in a demofilestorage: >>> from ZODB.DemoStorage import DemoStorage >>> storage = DemoStorage(base=base, changes=changes) If there are no transactions, the storage reports the lastTransaction of the base database: >>> storage.lastTransaction() == base.lastTransaction() True Let's add some data: >>> db = DB(storage) >>> conn = db.open() >>> items = conn.root()['1'].items() >>> items.sort() >>> items [('a', 1), ('b', 2)] >>> conn.root()['2'] = PersistentMapping({'a': 3, 'b':4}) >>> transaction.commit() >>> conn.root()['2']['c'] = 5 >>> transaction.commit() Here we can see that we haven't modified the base storage: >>> original_size == os.path.getsize('base.fs') True But we have modified the changes database: >>> len(changes) 2 Our lastTransaction reflects the lastTransaction of the changes: >>> storage.lastTransaction() > base.lastTransaction() True >>> storage.lastTransaction() == changes.lastTransaction() True Let's walk over some of the methods so we can see how we delegate to the new underlying storages: >>> from ZODB.utils import p64, u64 >>> storage.load(p64(0), '') == changes.load(p64(0), '') True >>> storage.load(p64(0), '') == base.load(p64(0), '') False >>> storage.load(p64(1), '') == base.load(p64(1), '') True >>> serial = base.getTid(p64(0)) >>> storage.loadSerial(p64(0), serial) == base.loadSerial(p64(0), serial) True >>> serial = changes.getTid(p64(0)) >>> storage.loadSerial(p64(0), serial) == changes.loadSerial(p64(0), ... serial) True The object id of the new object is quite random, and typically large: >>> print u64(conn.root()['2']._p_oid) 3553260803050964942 Let's look at some other methods: >>> storage.getName() "DemoStorage('base.fs', 'changes.fs')" >>> storage.sortKey() == changes.sortKey() True >>> storage.getSize() == changes.getSize() True >>> len(storage) == len(changes) True Undo methods are simply copied from the changes storage: >>> [getattr(storage, name) == getattr(changes, name) ... for name in ('supportsUndo', 'undo', 'undoLog', 'undoInfo') ... ] [True, True, True, True] >>> db.close() Closing demo storages ===================== Normally, when a demo storage is closed, it's base and changes storage are closed: >>> from ZODB.MappingStorage import MappingStorage >>> demo = DemoStorage(base=MappingStorage(), changes=MappingStorage()) >>> demo.close() >>> demo.base.opened(), demo.changes.opened() (False, False) You can pass constructor arguments to control whether the base and changes storages should be closed when the demo storage is closed: >>> demo = DemoStorage( ... base=MappingStorage(), changes=MappingStorage(), ... close_base_on_close=False, close_changes_on_close=False, ... ) >>> demo.close() >>> demo.base.opened(), demo.changes.opened() (True, True) Storage Stacking ================ A common use case is to stack demo storages. DemoStorage provides some helper functions to help with this. The push method, just creates a new demo storage who's base is the original demo storage: >>> demo = DemoStorage() >>> demo2 = demo.push() >>> demo2.base is demo True We can also supply an explicit changes storage, if we wish: >>> changes = MappingStorage() >>> demo3 = demo2.push(changes) >>> demo3.changes is changes, demo3.base is demo2 (True, True) The pop method closes the changes storage and returns the base *without* closing it: >>> demo3.pop() is demo2 True >>> changes.opened() False If storage returned by push is closed, the original storage isn't: >>> demo3.push().close() >>> demo2.opened() True Blob Support ============ DemoStorage supports Blobs if the changes database supports blobs. >>> import ZODB.blob >>> base = ZODB.blob.BlobStorage('base', FileStorage('base.fs')) >>> db = DB(base) >>> conn = db.open() >>> conn.root()['blob'] = ZODB.blob.Blob() >>> conn.root()['blob'].open('w').write('state 1') >>> transaction.commit() >>> db.close() >>> base = ZODB.blob.BlobStorage('base', ... FileStorage('base.fs', read_only=True)) >>> changes = ZODB.blob.BlobStorage('changes', ... FileStorage('changes.fs', create=True)) >>> storage = DemoStorage(base=base, changes=changes) >>> db = DB(storage) >>> conn = db.open() >>> conn.root()['blob'].open().read() 'state 1' >>> _ = transaction.begin() >>> conn.root()['blob'].open('w').write('state 2') >>> transaction.commit() >>> conn.root()['blob'].open().read() 'state 2' >>> storage.temporaryDirectory() == changes.temporaryDirectory() True >>> db.close() It isn't necessary for the base database to support blobs. >>> base = FileStorage('base.fs', read_only=True) >>> changes = ZODB.blob.BlobStorage('changes', FileStorage('changes.fs')) >>> storage = DemoStorage(base=base, changes=changes) >>> db = DB(storage) >>> conn = db.open() >>> conn.root()['blob'].open().read() 'state 2' >>> _ = transaction.begin() >>> conn.root()['blob2'] = ZODB.blob.Blob() >>> conn.root()['blob2'].open('w').write('state 1') >>> conn.root()['blob2'].open().read() 'state 1' >>> db.close() If the changes database is created implicitly, it will get a blob storage wrapped around it when necessary: >>> base = ZODB.blob.BlobStorage('base', ... FileStorage('base.fs', read_only=True)) >>> storage = DemoStorage(base=base) >>> type(storage.changes).__name__ 'MappingStorage' >>> db = DB(storage) >>> conn = db.open() >>> conn.root()['blob'].open().read() 'state 1' >>> type(storage.changes).__name__ 'BlobStorage' >>> _ = transaction.begin() >>> conn.root()['blob'].open('w').write('state 2') >>> transaction.commit() >>> conn.root()['blob'].open().read() 'state 2' >>> storage.temporaryDirectory() == storage.changes.temporaryDirectory() True >>> db.close() .. Check that the temporary directory is gone For now, it won't go until the storage does. >>> transaction.abort() >>> blobdir = storage.temporaryDirectory() >>> del storage, _ >>> import gc >>> _ = gc.collect() >>> import os >>> os.path.exists(blobdir) False ZConfig support =============== You can configure demo storages using ZConfig, using name, changes, and base options: >>> import ZODB.config >>> storage = ZODB.config.storageFromString(""" ... ... ... """) >>> storage.getName() "DemoStorage('MappingStorage', 'MappingStorage')" >>> storage = ZODB.config.storageFromString(""" ... ... ... path base.fs ... ... ... ... path changes.fs ... ... ... """) >>> storage.getName() "DemoStorage('base.fs', 'changes.fs')" >>> storage.close() >>> storage = ZODB.config.storageFromString(""" ... ... name bob ... ... path base.fs ... ... ... ... path changes.fs ... ... ... """) >>> storage.getName() 'bob' >>> storage.base.getName() 'base.fs' >>> storage.close() Generating OIDs =============== When asked for a new OID DemoStorage chooses a value and then verifies that neither the base or changes storages already contain that OID. It chooses values sequentially from random starting points, picking new starting points whenever a chosen value us already in the changes or base. Under rare circumstances an OID can be chosen that has already been handed out, but which hasn't yet been comitted. Lets verify that if the same OID is chosen twice during a transaction that everything will still work. To test this, we need to hack random.randint a bit. >>> import random >>> randint = random.randint >>> rv = 42 >>> def faux_randint(min, max): ... print 'called randint' ... global rv ... rv += 1000 ... return rv >>> random.randint = faux_randint Now, we create a demostorage. >>> storage = DemoStorage() called randint If we ask for an oid, we'll get 1042. >>> u64(storage.new_oid()) 1042 oids are allocated seuentially: >>> u64(storage.new_oid()) 1043 Now, we'll save 1044 in changes so that it has to pick a new one randomly. >>> t = transaction.get() >>> ZODB.tests.util.store(storage.changes, 1044) >>> u64(storage.new_oid()) called randint 2042 Now, we hack rv to 1042 is given out again and we'll save 2043 in base to force another attempt: >>> rv -= 1000 >>> ZODB.tests.util.store(storage.changes, 2043) >>> oid = storage.new_oid() called randint called randint >>> u64(oid) 3042 DemoStorage keeps up with the issued OIDs to know when not to reissue them... >>> oid in storage._issued_oids True ...but once data is stored with a given OID... >>> ZODB.tests.util.store(storage, oid) ...there's no need to remember it any longer: >>> oid in storage._issued_oids False >>> storage.close() .. restore randint >>> random.randint = randint .. restore time >>> time.time = real_time_time zope2.13-2.13.21/source/ZODB3/src/ZODB/FileStorage/0000755000175000017500000000000012214017464020012 5ustar arnauarnauzope2.13-2.13.21/source/ZODB3/src/ZODB/FileStorage/FileStorage.py0000644000175000017500000021303712214017464022576 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

We'll make some assertions about time, so we'll take it over: >>> now = 1229959248 >>> def faux_time(): ... global now ... now += 0.1 ... return now >>> import time >>> time_time = time.time >>> time.time = faux_time Commit a bunch of transactions: >>> import ZODB.FileStorage, transaction >>> db = ZODB.DB('data.fs') >>> tids = [db.storage.lastTransaction()] >>> poss = [db.storage._pos] >>> conn = db.open() >>> for i in range(100): ... conn.root()[i] = conn.root().__class__() ... transaction.commit() ... tids.append(db.storage.lastTransaction()) ... poss.append(db.storage._pos) Deciding where to start ----------------------- By default, we start at the beginning: >>> it = ZODB.FileStorage.FileIterator('data.fs') >>> it.next().tid == tids[0] True The file iterator has an optimization to deal with large files. It can serarch from either the front or the back of the file, depending on the starting transaction given. To see this, we'll turn on debug logging: >>> import logging, sys >>> old_log_level = logging.getLogger().getEffectiveLevel() >>> logging.getLogger().setLevel(logging.DEBUG) >>> handler = logging.StreamHandler(sys.stdout) >>> logging.getLogger().addHandler(handler) If we specify a start transaction, we'll scan forward or backward, as seems best and set the next record to that: >>> it = ZODB.FileStorage.FileIterator('data.fs', tids[0]) >>> it.next().tid == tids[0] True >>> it = ZODB.FileStorage.FileIterator('data.fs', tids[1]) Scan forward data.fs:4 looking for '\x03z\xbd\xd8\xd06\x9c\xcc' >>> it.next().tid == tids[1] True >>> it = ZODB.FileStorage.FileIterator('data.fs', tids[30]) Scan forward data.fs:4 looking for '\x03z\xbd\xd8\xdc\x96.\xcc' >>> it.next().tid == tids[30] True >>> it = ZODB.FileStorage.FileIterator('data.fs', tids[70]) Scan backward data.fs:117080 looking for '\x03z\xbd\xd8\xed\xa7>\xcc' >>> it.next().tid == tids[70] True >>> it = ZODB.FileStorage.FileIterator('data.fs', tids[-2]) Scan backward data.fs:117080 looking for '\x03z\xbd\xd8\xfa\x06\xd0\xcc' >>> it.next().tid == tids[-2] True >>> it = ZODB.FileStorage.FileIterator('data.fs', tids[-1]) >>> it.next().tid == tids[-1] True We can also supply a file position.

To define a FileStorage, you use a filestorage section, and define a path: >>> import ZODB.config >>> fs = ZODB.config.storageFromString(""" ... ... path my.fs ... ... """) >>> fs._file.name 'my.fs' >>> fs.close() There are a number of options we can provide: blob-dir If supplied, the file storage will provide blob support and this is the name of a directory to hold blob data. The directory will be created if it doeesn't exist. If no value (or an empty value) is provided, then no blob support will be provided. (You can still use a BlobStorage to provide blob support.) >>> fs = ZODB.config.storageFromString(""" ... ... path my.fs ... blob-dir blobs ... ... """) >>> fs._file.name 'my.fs' >>> import os >>> os.path.basename(fs.blob_dir) 'blobs' create Flag that indicates whether the storage should be truncated if it already exists. To demonstrate this, we'll first write some data: >>> db = ZODB.DB(fs) >>> conn = db.open() >>> import ZODB.blob, transaction >>> conn.root()[1] = ZODB.blob.Blob() >>> transaction.commit() >>> db.close() Then reopen with the create option: >>> fs = ZODB.config.storageFromString(""" ... ... path my.fs ... blob-dir blobs ... create true ... ... """) Because the file was truncated, we no-longer have object 0: >>> fs.load('\0'*8) Traceback (most recent call last): ... POSKeyError: 0x00 >>> sorted(os.listdir('blobs')) ['.layout', 'tmp'] >>> fs.close() read-only If true, only reads may be executed against the storage. Note that the "pack" operation is not considered a write operation and is still allowed on a read-only filestorage. >>> fs = ZODB.config.storageFromString(""" ... ... path my.fs ... read-only true ... ... """) >>> fs.isReadOnly() True >>> fs.close() quota Maximum allowed size of the storage file. Operations which would cause the size of the storage to exceed the quota will result in a ZODB.FileStorage.FileStorageQuotaError being raised. >>> fs = ZODB.config.storageFromString(""" ... ... path my.fs ... quota 10 ... ... """) >>> db = ZODB.DB(fs) # writes object 0 Traceback (most recent call last): ... FileStorageQuotaError: The storage quota has been exceeded. >>> fs.close() packer The dotten name (dotten module name and object name) of a packer object. This is used to provide an alternative pack implementation. To demonstrate this, we'll create a null packer that just prints some information about it's arguments: >>> def packer(storage, referencesf, stop, gc): ... print referencesf, storage is fs, gc, storage.pack_keep_old >>> ZODB.FileStorage.config_demo_printing_packer = packer >>> fs = ZODB.config.storageFromString(""" ... ... path my.fs ... packer ZODB.FileStorage.config_demo_printing_packer ... ... """) >>> import time >>> db = ZODB.DB(fs) # writes object 0 >>> fs.pack(time.time(), 42) 42 True True True >>> fs.close() If the packer contains a ':', then the text after the first ':' is interpreted as an expression. This is handy to pass limited configuration information to the packer: >>> def packer_factory(name): ... def packer(storage, referencesf, stop, gc): ... print repr(name), referencesf, storage is fs, gc, ... print storage.pack_keep_old ... return packer >>> ZODB.FileStorage.config_demo_printing_packer_factory = packer_factory >>> fs = ZODB.config.storageFromString(""" ... ... path my.fs ... packer ZODB.FileStorage:config_demo_printing_packer_factory('bob ') ... ... """) >>> import time >>> db = ZODB.DB(fs) # writes object 0 >>> fs.pack(time.time(), 42) 'bob ' 42 True True True >>> fs.close() pack-gc If false, then no garbage collection will be performed when packing. This can make packing go much faster and can avoid problems when objects are referenced only from other databases. >>> fs = ZODB.config.storageFromString(""" ... ... path my.fs ... packer ZODB.FileStorage.config_demo_printing_packer ... pack-gc false ... ... """) >>> fs.pack(time.time(), 42) 42 True False True Note that if we pass the gc option to pack, then this will override the value set in the configuration: >>> fs.pack(time.time(), 42, gc=True) 42 True True True >>> fs.close() pack-keep-old If false, then old files aren't kept when packing >>> fs = ZODB.config.storageFromString(""" ... ... path my.fs ... packer ZODB.FileStorage.config_demo_printing_packer ... pack-keep-old false ... ... """) >>> fs.pack(time.time(), 42) 42 True True False >>> fs.close() zope2.13-2.13.21/source/ZODB3/src/ZODB/FileStorage/fsdump.py0000644000175000017500000001101112214017464021654 0ustar arnauarnau############################################################################## # # Copyright (c) 2003 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

Note that, to be as realistic as possible with ZEO, you should run this script multiple times, to simulate multiple clients. Here's how this works. The script starts some number of threads. Each thread, sequentially executes jobs. There is a job producer that produces jobs. Input data are provided by a mail producer that hands out message from a mailbox. Execution continues until there is an error, which will normally occur when the mailbox is exhausted. Command-line options are used to provide job definitions. Job definitions have perameters of the form name=value. Jobs have 2 standard parameters: frequency=integer The frequency of the job. The default is 1. sleep=float The number os seconds to sleep before performing the job. The default is 0. Usage: loadmail2 [options] Options: -edit [frequency=integer] [sleep=float] Define an edit job. An edit job edits a random already-saved email message, deleting and inserting a random number of words. After editing the message, the message is (re)cataloged. -insert [number=int] [frequency=integer] [sleep=float] Insert some number of email messages. -index [number=int] [frequency=integer] [sleep=float] Insert and index (catalog) some number of email messages. -search [terms='word1 word2 ...'] [frequency=integer] [sleep=float] Search the catalog. A query is givem with one or more terms as would be entered into a typical seach box. If no query is given, then queries will be randomly selected based on a set of built-in word list. -setup Set up the database. This will delete any existing Data.fs file. (Of course, this may have no effect, if there is a custom_zodb that defined a different storage.) It also adds a mail folder and a catalog. -options file Read options from the given file. Th efile should be a python source file that defines a sequence of options named 'options'. -threads n Specify the number of threads to execute. If not specified (< 2), then jobs are run in a single (main) thread. -mbox filename Specify the mailbox for getting input data. There is a (lame) syntax for providing options within the filename. The filename may be followed by up to 3 integers, min, max, and start: -mbox 'foo.mbox 0 100 10000' The messages from min to max will be read from the mailbox. They will be assigned message numbers starting with start. So, in the example above, we read the first hundred messages and assign thgem message numbers starting with 10001. The maxmum can be given as a negative number, in which case, it specifies the number of messages to read. The start defaults to the minimum. The following two options: -mbox 'foo.mbox 300 400 300' and -mbox 'foo.mbox 300 -100' are equivalent $Id: zodbload.py 113734 2010-06-21 15:33:46Z ctheune $ """ import mailbox import math import os

By default, an incremental backup is made if possible (e.g., if a pack has occurred since the last incremental backup, a full backup is necessary). -Q / --quick Verify via md5 checksum only the last incremental written. This significantly reduces the disk i/o at the (theoretical) cost of inconsistency. This is a probabilistic way of determining whether a full backup is necessary. -z / --gzip Compress with gzip the backup files. Uses the default zlib compression level. By default, gzip compression is not used. -k / --kill-old-on-full If a full backup is created, remove any prior full or incremental backup files (and associated metadata files) from the repository directory.

Specify UTC (not local) time. yyyy-mm-dd[-hh[-mm[-ss]]] By default, current time is used. -o filename --output=filename Write recovered ZODB to given file. By default, the file is written to stdout.

Some are more useful than others. If you install ZODB using distutils ("python setup.py install"), a few of these will be installed. Unless otherwise noted, these scripts are invoked with the name of the Data.fs file as their only argument. Example: checkbtrees.py data.fs. analyze.py -- a transaction analyzer for FileStorage Reports on the data in a FileStorage. The report is organized by class. It shows total data, as well as separate reports for current and historical revisions of objects. checkbtrees.py -- checks BTrees in a FileStorage for corruption Attempts to find all the BTrees contained in a Data.fs, calls their _check() methods, and runs them through BTrees.check.check(). fsdump.py -- summarize FileStorage contents, one line per revision Prints a report of FileStorage contents, with one line for each transaction and one line for each data record in that transaction. Includes time stamps, file positions, and class names. fsoids.py -- trace all uses of specified oids in a FileStorage For heavy debugging. A set of oids is specified by text file listing and/or command line. A report is generated showing all uses of these oids in the database: all new-revision creation/modifications, all references from all revisions of other objects, and all creation undos. fstest.py -- simple consistency checker for FileStorage usage: fstest.py [-v] data.fs The fstest tool will scan all the data in a FileStorage and report an error if it finds any corrupt transaction data. The tool will print a message when the first error is detected an exit. The tool accepts one or more -v arguments. If a single -v is used, it will print a line of text for each transaction record it encounters. If two -v arguments are used, it will also print a line of text for each object. The objects for a transaction will be printed before the transaction itself. Note: It does not check the consistency of the object pickles. It is possible for the damage to occur only in the part of the file that stores object pickles. Those errors will go undetected. space.py -- report space used by objects in a FileStorage usage: space.py [-v] data.fs This ignores revisions and versions. netspace.py -- hackish attempt to report on size of objects usage: netspace.py [-P | -v] data.fs -P: do a pack first -v: print info for all objects, even if a traversal path isn't found Traverses objects from the database root and attempts to calculate size of object, including all reachable subobjects. parsezeolog.py -- parse BLATHER logs from ZEO server This script may be obsolete. It has not been tested against the current log output of the ZEO server. Reports on the time and size of transactions committed by a ZEO server, by inspecting log messages at BLATHER level. repozo.py -- incremental backup utility for FileStorage Run the script with the -h option to see usage details. timeout.py -- script to test transaction timeout usage: timeout.py address delay [storage-name] This script connects to a storage, begins a transaction, calls store() and tpc_vote(), and then sleeps forever. This should trigger the transaction timeout feature of the server. zodbload.py -- exercise ZODB under a heavy synthesized Zope-like load See the module docstring for details. Note that this script requires Zope. New in ZODB3 3.1.4. fsrefs.py -- check FileStorage for dangling references fstail.py -- display the most recent transactions in a FileStorage usage: fstail.py [-n nxtn] data.fs The most recent ntxn transactions are displayed, to stdout. Optional argument -n specifies ntxn, and defaults to 10. migrate.py -- do a storage migration and gather statistics See the module docstring for details. zope2.13-2.13.21/source/ZODB3/src/ZODB/scripts/referrers.py0000644000175000017500000000201512214017464021644 0ustar arnauarnau############################################################################## # # Copyright (c) 2005 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

It's hard to explain exactly what it does because it relies on undocumented features in Python's cPickle module: many of the crucial steps of loading an object are taken, but application objects aren't actually created. This saves a lot of time, and allows fsrefs to be run even if the code implementing the object classes isn't available. A read-only connection to the specified FileStorage is made, but it is not recommended to run fsrefs against a live FileStorage. Because a live FileStorage is mutating while fsrefs runs, it's not possible for fsrefs to get a wholly consistent view of the database across the entire time fsrefs is running; spurious error messages may result. fsrefs doesn't normally produce any output. If an object fails to load, the oid of the object is given in a message saying so, and if -v was specified then the traceback corresponding to the load failure is also displayed (this is the only effect of the -v flag). Three other kinds of errors are also detected, when an object O loads OK, and directly refers to a persistent object P but there's a problem with P: - If P doesn't exist in the database, a message saying so is displayed. The unsatisifiable reference to P is often called a "dangling reference"; P is called "missing" in the error output. - If the current state of the database is such that P's creation has been undone, then P can't be loaded either. This is also a kind of dangling reference, but is identified as "object creation was undone". - If P can't be loaded (but does exist in the database), a message saying that O refers to an object that can't be loaded is displayed. fsrefs also (indirectly) checks that the .index file is sane, because fsrefs uses the index to get its idea of what constitutes "all the objects in the database". Note these limitations: because fsrefs only looks at the current revision of objects, it does not attempt to load objects in versions, or non-current revisions of objects; therefore fsrefs cannot find problems in versions or in non-current revisions.

It provides a referrers method that takes an iterable storage object. It returns a dictionary mapping object ids to lists of referrer object versions, which each version is a tuple an object id nd serial nummber. To see how this works, we'll create a small database: >>> import transaction >>> from persistent.mapping import PersistentMapping >>> from ZODB.FileStorage import FileStorage >>> from ZODB.DB import DB >>> import os, tempfile >>> dest = tempfile.mkdtemp() >>> fs = FileStorage(os.path.join(dest, 'Data.fs')) >>> db = DB(fs) >>> conn = db.open() >>> conn.root()['a'] = PersistentMapping() >>> conn.root()['b'] = PersistentMapping() >>> transaction.commit() >>> roid = conn.root()._p_oid >>> aoid = conn.root()['a']._p_oid >>> boid = conn.root()['b']._p_oid >>> s1 = conn.root()['b']._p_serial >>> conn.root()['a']['b'] = conn.root()['b'] >>> transaction.commit() >>> s2 = conn.root()['a']._p_serial Now we'll get the storage and compute the referrers: >>> import ZODB.scripts.referrers >>> referrers = ZODB.scripts.referrers.referrers(fs) >>> referrers[boid] == [(roid, s1), (aoid, s2)] True .. Cleanup >>> db.close() zope2.13-2.13.21/source/ZODB3/src/ZODB/scripts/tests/test_repozo.py0000644000175000017500000010332312214017464023370 0ustar arnauarnau############################################################################## # # Copyright (c) 2004-2009 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

This is very similar to a standard storage's copyTransactionsFrom() method, except that it's geared to run as a script, and it collects useful pieces of information as it's working. This script can be used to stress test a storage since it blasts transactions at it as fast as possible. You can get a good sense of the performance of a storage by running this script. Actually it just counts the size of pickles in the transaction via the iterator protocol, so storage overheads aren't counted. Usage: %(PROGRAM)s [options] [source-storage-args] [destination-storage-args] Options: -S sourcetype --stype=sourcetype This is the name of a recognized type for the source database. Use -T to print out the known types. Defaults to "file". -D desttype --dtype=desttype This is the name of the recognized type for the destination database. Use -T to print out the known types. Defaults to "file". -o filename --output=filename Print results in filename, otherwise stdout. -m txncount --max=txncount Stop after committing txncount transactions. -k txncount --skip=txncount Skip the first txncount transactions. -p/--profile Turn on specialized profiling. -t/--timestamps Print tids as timestamps. -T/--storage_types Print all the recognized storage types and exit. -v/--verbose Turns on verbose output. Multiple -v options increase the verbosity. -h/--help Print this message and exit. Positional arguments: source-storage-args: Semicolon separated list of arguments for the source storage, as key=val pairs. E.g.

Flag that indicates whether the storage should be truncated if it already exists. If true, only reads may be executed against the storage. Note that the "pack" operation is not considered a write operation and is still allowed on a read-only filestorage. Maximum allowed size of the storage file. Operations which would cause the size of the storage to exceed the quota will result in a ZODB.FileStorage.FileStorageQuotaError being raised. The dotted name (dotted module name and object name) of a packer object. This is used to provide an alternative pack implementation. If false, then no garbage collection will be performed when packing. This can make packing go much faster and can avoid problems when objects are referenced only from other databases. If true, a copy of the database before packing is kept in a ".old" file. Path name to the blob cache directory. Tells whether the cache is a shared writable directory and that the ZEO protocol should not transfer the file but only the filename when committing. Maximum size of the ZEO blob cache, in bytes. If not set, then the cache size isn't checked and the blob directory will grow without bound. This option is ignored if shared_blob_dir is true. ZEO check size as percent of blob_cache_size. The ZEO cache size will be checked when this many bytes have been loaded into the cache. Defaults to 10% of the blob cache size. This option is ignored if shared_blob_dir is true. The name of the storage that the client wants to use. If the ZEO server serves more than one storage, the client selects the storage it wants to use by name. The default name is '1', which is also the default name for the ZEO server. The maximum size of the client cache, in bytes, KB or MB. The storage name. If unspecified, the address of the server will be used as the name. Enables persistent cache files. The string passed here is used to construct the cache filenames. If it is not specified, the client creates a temporary cache that will only be used by the current object. The directory where persistent cache files are stored. By default cache files, if they are persistent, are stored in the current directory. The minimum delay in seconds between attempts to connect to the server, in seconds. Defaults to 5 seconds. The maximum delay in seconds between attempts to connect to the server, in seconds. Defaults to 300 seconds. A boolean indicating whether the constructor should wait for the client to connect to the server and verify the cache before returning. The default is true. A flag indicating whether this should be a read-only storage, defaulting to false (i.e. writing is allowed by default). A flag indicating whether a read-only remote storage should be acceptable as a fallback when no writable storages are available. Defaults to false. At most one of read_only and read_only_fallback should be true. The authentication username of the server. The authentication password of the server. The authentication realm of the server. Some authentication schemes use a realm to identify the logic set of usernames that are accepted by this server. A flag indicating whether the client cache should be dropped instead of an expensive verification. A label for the client in server logs

Target size, in number of objects, of each connection's object cache. Target size, in total estimated size for objects, of each connection's object cache. "0" means no limit. The expected maximum number of simultaneously open connections. There is no hard limit (as many connections as are requested will be opened, until system resources are exhausted). Exceeding pool-size connections causes a warning message to be logged, and exceeding twice pool-size connections causes a critical message to be logged. The minimum interval that an unused (non-historical) connection should be kept. The expected maximum total number of historical connections simultaneously open. Target size, in number of objects, of each historical connection's object cache. Target size, in total estimated size of objects, of each historical connection's object cache. The minimum interval that an unused historical connection should be kept. When multidatabases are in use, this is the name given to this database in the collection. The name must be unique across all databases in the collection. The collection must also be given a mapping from its databases' names to their databases, but that cannot be specified in a ZODB config file. Applications using multidatabases typical supply a way to configure the mapping in their own config files, using the "databases" parameter of a DB constructor. If set to false, implicit cross references (the only kind currently possible) are disallowed. Path name to the blob storage directory.

This can enable full-context application level conflict resolution, historical exploration and preparation for reverts, or even the use of a historical database revision as "production" while development continues on a "development" head. A database can be opened historically ``at`` or ``before`` a given transaction serial or datetime. Here's a simple example. It should work with any storage that supports ``loadBefore``. We'll begin our example with a fairly standard set up. We - make a storage and a database; - open a normal connection; - modify the database through the connection; - commit a transaction, remembering the time in UTC; - modify the database again; and - commit a transaction. >>> import ZODB.MappingStorage >>> db = ZODB.MappingStorage.DB() >>> conn = db.open() >>> import persistent.mapping >>> conn.root()['first'] = persistent.mapping.PersistentMapping(count=0) >>> import transaction >>> transaction.commit() We wait for some time to pass, record he time, and then make some other changes. >>> import time >>> time.sleep(.01) >>> import datetime >>> now = datetime.datetime.utcnow() >>> time.sleep(.01) >>> root = conn.root() >>> root['second'] = persistent.mapping.PersistentMapping() >>> root['first']['count'] += 1 >>> transaction.commit() Now we will show a historical connection. We'll open one using the ``now`` value we generated above, and then demonstrate that the state of the original connection, at the mutable head of the database, is different than the historical state. >>> transaction1 = transaction.TransactionManager() >>> historical_conn = db.open(transaction_manager=transaction1, at=now) >>> sorted(conn.root().keys()) ['first', 'second'] >>> conn.root()['first']['count'] 1 >>> historical_conn.root().keys() ['first'] >>> historical_conn.root()['first']['count'] 0 Moreover, the historical connection cannot commit changes. >>> historical_conn.root()['first']['count'] += 1 >>> historical_conn.root()['first']['count'] 1 >>> transaction1.commit() Traceback (most recent call last): ... ReadOnlyHistoryError >>> transaction1.abort() >>> historical_conn.root()['first']['count'] 0 (It is because of the mutable behavior outside of transactional semantics that we must have a separate connection, and associated object cache, per thread, even though the semantics should be readonly.) As demonstrated, a timezone-naive datetime will be interpreted as UTC. You can also pass a timezone-aware datetime or a serial (transaction id). Here's opening with a serial--the serial of the root at the time of the first commit. >>> historical_serial = historical_conn.root()._p_serial >>> historical_conn.close() >>> historical_conn = db.open(transaction_manager=transaction1, ... at=historical_serial) >>> historical_conn.root().keys() ['first'] >>> historical_conn.root()['first']['count'] 0 >>> historical_conn.close() We've shown the ``at`` argument. You can also ask to look ``before`` a datetime or serial. (It's an error to pass both [#not_both]_) In this example, we're looking at the database immediately prior to the most recent change to the root. >>> serial = conn.root()._p_serial >>> historical_conn = db.open( ... transaction_manager=transaction1, before=serial) >>> historical_conn.root().keys() ['first'] >>> historical_conn.root()['first']['count'] 0 In fact, ``at`` arguments are translated into ``before`` values because the underlying mechanism is a storage's loadBefore method. When you look at a connection's ``before`` attribute, it is normalized into a ``before`` serial, no matter what you pass into ``db.open``. >>> print conn.before None >>> historical_conn.before == serial True >>> conn.close() Configuration ============= Like normal connections, the database lets you set how many total historical connections can be active without generating a warning, and how many objects should be kept in each historical connection's object cache. >>> db.getHistoricalPoolSize() 3 >>> db.setHistoricalPoolSize(4) >>> db.getHistoricalPoolSize() 4 >>> db.getHistoricalCacheSize() 1000 >>> db.setHistoricalCacheSize(2000) >>> db.getHistoricalCacheSize() 2000 In addition, you can specify the minimum number of seconds that an unused historical connection should be kept. >>> db.getHistoricalTimeout() 300 >>> db.setHistoricalTimeout(400) >>> db.getHistoricalTimeout() 400 All three of these values can be specified in a ZConfig file. >>> import ZODB.config >>> db2 = ZODB.config.databaseFromString(''' ... ... ... historical-pool-size 3 ... historical-cache-size 1500 ... historical-timeout 6m ... ... ''') >>> db2.getHistoricalPoolSize() 3 >>> db2.getHistoricalCacheSize() 1500 >>> db2.getHistoricalTimeout() 360 The pool lets us reuse connections. To see this, we'll open some connections, close them, and then open them again: >>> conns1 = [db2.open(before=serial) for i in range(4)] >>> _ = [c.close() for c in conns1] >>> conns2 = [db2.open(before=serial) for i in range(4)] Now let's look at what we got. The first connection in conns 2 is the last connection in conns1, because it was the last connection closed. >>> conns2[0] is conns1[-1] True Also for the next two: >>> (conns2[1] is conns1[-2]), (conns2[2] is conns1[-3]) (True, True) But not for the last: >>> conns2[3] is conns1[-4] False Because the pool size was set to 3. Connections are also discarded if they haven't been used in a while. To see this, let's close two of the connections: >>> conns2[0].close(); conns2[1].close() We'l also set the historical timeout to be very low: >>> db2.setHistoricalTimeout(.01) >>> time.sleep(.1) >>> conns2[2].close(); conns2[3].close() Now, when we open 4 connections: >>> conns1 = [db2.open(before=serial) for i in range(4)] We'll see that only the last 2 connections from conn2 are in the result: >>> [c in conns1 for c in conns2] [False, False, True, True] If you change the historical cache size, that changes the size of the persistent cache on our connection. >>> historical_conn._cache.cache_size 2000 >>> db.setHistoricalCacheSize(1500) >>> historical_conn._cache.cache_size 1500 Invalidations ============= Invalidations are ignored for historical connections. This is another white box test. >>> historical_conn = db.open( ... transaction_manager=transaction1, at=serial) >>> conn = db.open() >>> sorted(conn.root().keys()) ['first', 'second'] >>> conn.root()['first']['count'] 1 >>> sorted(historical_conn.root().keys()) ['first', 'second'] >>> historical_conn.root()['first']['count'] 1 >>> conn.root()['first']['count'] += 1 >>> conn.root()['third'] = persistent.mapping.PersistentMapping() >>> transaction.commit() >>> len(historical_conn._invalidated) 0 >>> historical_conn.close() Note that if you try to open an historical connection to a time in the future, you will get an error. >>> historical_conn = db.open( ... at=datetime.datetime.utcnow()+datetime.timedelta(1)) Traceback (most recent call last): ... ValueError: cannot open an historical connection in the future. Warnings ======== First, if you use datetimes to get a historical connection, be aware that the conversion from datetime to transaction id has some pitfalls. Generally, the transaction ids in the database are only as time-accurate as the system clock was when the transaction id was created. Moreover, leap seconds are handled somewhat naively in the ZODB (largely because they are handled naively in Unix/ POSIX time) so any minute that contains a leap second may contain serials that are a bit off. This is not generally a problem for the ZODB, because serials are guaranteed to increase, but it does highlight the fact that serials are not guaranteed to be accurately connected to time. Generally, they are about as reliable as time.time. Second, historical connections currently introduce potentially wide variance in memory requirements for the applications. Since you can open up many connections to different serials, and each gets their own pool, you may collect quite a few connections. For now, at least, if you use this feature you need to be particularly careful of your memory usage. Get rid of pools when you know you can, and reuse the exact same values for ``at`` or ``before`` when possible. If historical connections are used for conflict resolution, these connections will probably be temporary--not saved in a pool--so that the extra memory usage would also be brief and unlikely to overlap. .. cleanup >>> db.close() >>> db2.close() .. ......... .. ..

The Connection object serves as a data manager. The root() method on a Connection returns the root object for the database. This object and all objects reachable from it are associated with the Connection that loaded them. When a transaction commits, it uses the Connection to store modified objects. Typical use of ZODB is for each thread to have its own Connection and that no thread should have more than one Connection to the same database. A thread is associated with a Connection by loading objects from that Connection. Objects loaded by one thread should not be used by another thread. A Connection can be frozen to a serial--a transaction id, a single point in history-- when it is created. By default, a Connection is not associated with a serial; it uses current data. A Connection frozen to a serial is read-only. Each Connection provides an isolated, consistent view of the database, by managing independent copies of objects in the database. At transaction boundaries, these copies are updated to reflect the current state of the database. You should not instantiate this class directly; instead call the open() method of a DB instance. In many applications, root() is the only method of the Connection that you will need to use. Synchronization --------------- A Connection instance is not thread-safe. It is designed to support a thread model where each thread has its own transaction. If an application has more than one thread that uses the connection or the transaction the connection is registered with, the application should provide locking. The Connection manages movement of objects in and out of object storage. TODO: We should document an intended API for using a Connection via multiple threads. TODO: We should explain that the Connection has a cache and that multiple calls to get() will return a reference to the same object, provided that one of the earlier objects is still referenced. Object identity is preserved within a connection, but not across connections. TODO: Mention the database pool. A database connection always presents a consistent view of the objects in the database, although it may not always present the most current revision of any particular object. Modifications made by concurrent transactions are not visible until the next transaction boundary (abort or commit). Two options affect consistency. By default, the mvcc and synch options are enabled by default. If you pass mvcc=False to db.open(), the Connection will never read non-current revisions of an object. Instead it will raise a ReadConflictError to indicate that the current revision is unavailable because it was written after the current transaction began. The logic for handling modifications assumes that the thread that opened a Connection (called db.open()) is the thread that will use the Connection. If this is not true, you should pass synch=False to db.open(). When the synch option is disabled, some transaction boundaries will be missed by the Connection; in particular, if a transaction does not involve any modifications to objects loaded from the Connection and synch is disabled, the Connection will miss the transaction boundary. Two examples of this behavior are db.undo() and read-only transactions.

There are methods in IStorage and in derived interfaces that provide information about the current revisions (tids) for objects or for the database as a whole. It is critical for the proper working of ZODB that the resulting tids are increasing with respect to the object identifier given or to the databases. That is, if there are 2 results for an object or for the database, R1 and R2, such that R1 is returned before R2, then the tid returned by R2 must be greater than or equal to the tid returned by R1. (When thinking about results for the database, think of these as results for all objects in the database.) This implies some sort of locking strategy. The key method is tcp_finish, which causes new tids to be generated and also, through the callback passed to it, returns new current tids for the objects stored in a transaction and for the database as a whole.

"id`" A string uniquely identifying the transaction to the storage. If it's desired to undo this transaction, this is the `transaction_id` to pass to `undo()`. In addition, if any name+value pairs were added to the transaction by `setExtendedInfo()`, those may be added to the transaction description mapping too (for example, FileStorage's `undoLog()` does this). `filter` is a callable, taking one argument. A transaction description mapping is passed to `filter` for each potentially undoable transaction. The sequence returned by `undoLog()` excludes descriptions for which `filter` returns a false value. By default, `filter` always returns a true value. ZEO note: Arbitrary callables cannot be passed from a ZEO client to a ZEO server, and a ZEO client's implementation of `undoLog()` ignores any `filter` argument that may be passed. ZEO clients should use the related `undoInfo()` method instead (if they want to do filtering). Now picture a list containing descriptions of all undoable transactions that pass the filter, most recent transaction first (at index 0). The `first` and `last` arguments specify the slice of this (conceptual) list to be returned: `first`: This is the index of the first transaction description in the slice. It must be >= 0. `last`: If >= 0, first:last acts like a Python slice, selecting the descriptions at indices `first`, first+1, ..., up to but not including index `last`. At most last-first descriptions are in the slice, and `last` should be at least as large as `first` in this case. If `last` is less than 0, then abs(last) is taken to be the maximum number of descriptions in the slice (which still begins at index `first`). When `last` < 0, the same effect could be gotten by passing the positive first-last for `last` instead.

In other words, only extensions (or supersets) of `specification` match.

""" # DB pass-through class IMVCCStorage(IStorage): """A storage that provides MVCC semantics internally. MVCC (multi-version concurrency control) means each user of a database has a snapshot view of the database. The snapshot view does not change, even if concurrent connections commit transactions, until a transaction boundary. Relational databases that support serializable transaction isolation provide MVCC. Storages that implement IMVCCStorage, such as RelStorage, provide MVCC semantics at the ZODB storage layer. When ZODB.Connection uses a storage that implements IMVCCStorage, each connection uses a connection-specific storage instance, and that storage instance provides a snapshot of the database. By contrast, storages that do not implement IMVCCStorage, such as FileStorage, rely on ZODB.Connection to provide MVCC semantics, so in that case, one storage instance is shared by many ZODB.Connections. Applications that use ZODB.Connection always have a snapshot view of the database; IMVCCStorage only modifies which layer of ZODB provides MVCC. Furthermore, IMVCCStorage changes the way object invalidation works. An essential feature of ZODB is the propagation of object invalidation messages to keep in-memory caches up to date. Storages like FileStorage and ZEO.ClientStorage send invalidation messages to all other Connection instances at transaction commit time. Storages that implement IMVCCStorage, on the other hand, expect the ZODB.Connection to poll for a list of invalidated objects. Certain methods of IMVCCStorage implementations open persistent back end database sessions and retain the sessions even after the method call finishes:: load loadEx loadSerial loadBefore store restore new_oid history tpc_begin tpc_vote tpc_abort tpc_finish If you know that the storage instance will no longer be used after calling any of these methods, you should call the release method to release the persistent sessions.

This module exists largely to test changes made to support Zope 2 ZClasses, with their historical flaws. The persistentclass module provides a meta class that can be used to implement persistent classes. Persistent classes have the following properties: - They cannot be turned into ghosts - They can only contain picklable subobjects - They don't live in regular file-system modules Let's look at an example: >>> def __init__(self, name): ... self.name = name >>> def foo(self): ... return self.name, self.kind >>> import ZODB.persistentclass >>> class C: ... __metaclass__ = ZODB.persistentclass.PersistentMetaClass ... __init__ = __init__ ... __module__ = '__zodb__' ... foo = foo ... kind = 'sample' This example is obviously a bit contrived. In particular, we defined the methods outside of the class. Why? Because all of the items in a persistent class must be picklable. We defined the methods as global functions to make them picklable. Also note that we explictly set the module. Persistent classes don't live in normal Python modules. Rather, they live in the database. We use information in ``__module__`` to record where in the database. When we want to use a database, we will need to supply a custom class factory to load instances of the class. The class we created works a lot like other persistent objects. It has standard standard persistent attributes: >>> C._p_oid >>> C._p_jar >>> C._p_serial >>> C._p_changed False Because we haven't saved the object, the jar, oid, and serial are all None and it's not changed. We can create and use instances of the class: >>> c = C('first') >>> c.foo() ('first', 'sample') We can modify the class and none of the persistent attributes will change because the object hasn't been saved. >>> def bar(self): ... print 'bar', self.name >>> C.bar = bar >>> c.bar() bar first >>> C._p_oid >>> C._p_jar >>> C._p_serial >>> C._p_changed False Now, we can store the class in a database. We're going to use an explicit transaction manager so that we can show parallel transactions without having to use threads. >>> import transaction >>> tm = transaction.TransactionManager() >>> connection = some_database.open(transaction_manager=tm) >>> connection.root()['C'] = C >>> tm.commit() Now, if we look at the persistence variables, we'll see that they have values: >>> C._p_oid '\x00\x00\x00\x00\x00\x00\x00\x01' >>> C._p_jar is not None True >>> C._p_serial is not None True >>> C._p_changed False Now, if we modify the class: >>> def baz(self): ... print 'baz', self.name >>> C.baz = baz >>> c.baz() baz first We'll see that the class has changed: >>> C._p_changed True If we abort the transaction: >>> tm.abort() Then the class will return to it's prior state: >>> c.baz() Traceback (most recent call last): ... AttributeError: 'C' object has no attribute 'baz' >>> c.bar() bar first We can open another connection and access the class there. >>> tm2 = transaction.TransactionManager() >>> connection2 = some_database.open(transaction_manager=tm2) >>> C2 = connection2.root()['C'] >>> c2 = C2('other') >>> c2.bar() bar other If we make changes without commiting them: >>> C.bar = baz >>> c.bar() baz first >>> C is C2 False Other connections are unaffected: >>> connection2.sync() >>> c2.bar() bar other Until we commit: >>> tm.commit() >>> connection2.sync() >>> c2.bar() baz other Similarly, we don't see changes made in other connections: >>> C2.color = 'red' >>> tm2.commit() >>> c.color Traceback (most recent call last): ... AttributeError: 'C' object has no attribute 'color' until we sync: >>> connection.sync() >>> c.color 'red' Instances of Persistent Classes ------------------------------- We can, of course, store instances of persistent classes in the database: >>> c.color = 'blue' >>> connection.root()['c'] = c >>> tm.commit() >>> connection2.sync() >>> connection2.root()['c'].color 'blue' NOTE: If a non-persistent instance of a persistent class is copied, the class may be copied as well. This is usually not the desired result. Persistent instances of persistent classes ------------------------------------------ Persistent instances of persistent classes are handled differently than normal instances. When we copy a persistent instances of a persistent class, we want to avoid copying the class. Lets create a persistent class that subclasses Persistent: >>> import persistent >>> class P(persistent.Persistent, C): ... __module__ = '__zodb__' ... color = 'green' >>> connection.root()['P'] = P >>> import persistent.mapping >>> connection.root()['obs'] = persistent.mapping.PersistentMapping() >>> p = P('p') >>> connection.root()['obs']['p'] = p >>> tm.commit() You might be wondering why we didn't just stick 'p' into the root object. We created an intermediate persistent object instead. We are storing persistent classes in the root object. To create a ghost for a persistent instance of a persistent class, we need to be able to be able to access the root object and it must be loaded first. If the instance was in the root object, we'd be unable to create it while loading the root object. Now, if we try to load it, we get a broken oject: >>> connection2.sync() >>> connection2.root()['obs']['p'] because the module, `__zodb__` can't be loaded. We need to provide a class factory that knows about this special module. Here we'll supply a sample class factory that looks up a class name in the database root if the module is `__zodb__`. It falls back to the normal class lookup for other modules: >>> from ZODB.broken import find_global >>> def classFactory(connection, modulename, globalname): ... if modulename == '__zodb__': ... return connection.root()[globalname] ... return find_global(modulename, globalname) >>> some_database.classFactory = classFactory Normally, the classFactory should be set before a database is opened. We'll reopen the connections we're using. We'll assign the old connections to a variable first to prevent getting them from the connection pool: >>> old = connection, connection2 >>> connection = some_database.open(transaction_manager=tm) >>> connection2 = some_database.open(transaction_manager=tm2) Now, we can read the object: >>> connection2.root()['obs']['p'].color 'green' >>> connection2.root()['obs']['p'].color = 'blue' >>> tm2.commit() >>> connection.sync() >>> p = connection.root()['obs']['p'] >>> p.color 'blue' Copying ------- If we copy an instance via export/import, the copy and the original share the same class: >>> file = connection.exportFile(p._p_oid) >>> file.seek(0) >>> cp = connection.importFile(file) >>> file.close() >>> cp.color 'blue' >>> cp is not p True >>> cp.__class__ is p.__class__ True >>> tm.abort() XXX test abort of import zope2.13-2.13.21/source/ZODB3/src/ZODB/ConflictResolution.txt0000644000175000017500000004700612214017464022203 0ustar arnauarnau=================== Conflict Resolution =================== Overview ======== Conflict resolution is a way to resolve transaction conflicts that would otherwise abort a transaction. As such, it risks data integrity in order to try to avoid throwing away potentially computationally expensive transactions. The risk of harming data integrity should not be underestimated. Writing conflict resolution code takes some responsibility for transactional integrity away from the ZODB, and puts it in the hands of the developer writing the conflict resolution code. The current conflict resolution code is implemented with a storage mix-in found in ZODB/ConflictResolution.py. The idea's proposal, and an explanation of the interface, can be found here: http://www.zope.org/Members/jim/ZODB/ApplicationLevelConflictResolution Here is the most pertinent section, somewhat modified for this document's use: A new interface is proposed to allow object authors to provide a method for resolving conflicts. When a conflict is detected, then the database checks to see if the class of the object being saved defines the method, _p_resolveConflict. If the method is defined, then the method is called on the object. If the method succeeds, then the object change can be committed, otherwise a ConflictError is raised as usual. def _p_resolveConflict(oldState, savedState, newState): Return the state of the object after resolving different changes. Arguments: oldState The state of the object that the changes made by the current transaction were based on. The method is permitted to modify this value. savedState The state of the object that is currently stored in the database. This state was written after oldState and reflects changes made by a transaction that committed before the current transaction. The method is permitted to modify this value. newState The state after changes made by the current transaction. The method is not permitted to modify this value. This method should compute a new state by merging changes reflected in savedState and newState, relative to oldState. If the method cannot resolve the changes, then it should raise ZODB.POSException.ConflictError. Consider an extremely simple example, a counter:: from persistent import Persistent class PCounter(Persistent): '`value` is readonly; increment it with `inc`.' _val = 0 def inc(self): self._val += 1 @property def value(self): return self._val def _p_resolveConflict(self, oldState, savedState, newState): oldState['_val'] = ( savedState.get('_val', 0) + newState.get('_val', 0) - oldState.get('_val', 0)) return oldState .. -> src >>> import ConflictResolution_txt >>> exec src in ConflictResolution_txt.__dict__ >>> PCounter = ConflictResolution_txt.PCounter >>> PCounter.__module__ = 'ConflictResolution_txt' By "state", the excerpt above means the value used by __getstate__ and __setstate__: a dictionary, in most cases. We'll look at more details below, but let's continue the example above with a simple successful resolution story. First we create a storage and a database, and put a PCounter in the database. >>> import ZODB >>> db = ZODB.DB('Data.fs') >>> import transaction >>> tm_A = transaction.TransactionManager() >>> conn_A = db.open(transaction_manager=tm_A) >>> p_A = conn_A.root()['p'] = PCounter() >>> p_A.value 0 >>> tm_A.commit() Now get another copy of 'p' so we can make a conflict. Think of `conn_A` (connection A) as one thread, and `conn_B` (connection B) as a concurrent thread. `p_A` is a view on the object in the first connection, and `p_B` is a view on *the same persistent object* in the second connection. >>> tm_B = transaction.TransactionManager() >>> conn_B = db.open(transaction_manager=tm_B) >>> p_B = conn_B.root()['p'] >>> p_B.value 0 >>> p_A._p_oid == p_B._p_oid True Now we can make a conflict, and see it resolved. >>> p_A.inc() >>> p_A.value 1 >>> p_B.inc() >>> p_B.value 1 >>> tm_B.commit() >>> p_B.value 1 >>> tm_A.commit() >>> p_A.value 2 We need to synchronize connection B, in any of a variety of ways, to see the change from connection A. >>> p_B.value 1 >>> trans = tm_B.begin() >>> p_B.value 2 A very similar class found in real world use is BTrees.Length.Length. This conflict resolution approach is simple, yet powerful. However, it has a few caveats and rough edges in practice. The simplicity, then, is a bit of a disguise. Again, be warned, writing conflict resolution code means that you claim significant responsibilty for your data integrity. Because of the rough edges, the current conflict resolution approach is slated for change (as of this writing, according to Jim Fulton, the ZODB primary author and maintainer). Others have talked about different approaches as well (see, for instance, http://www.python.org/~jeremy/weblog/031031c.html). But for now, the _p_resolveConflict method is what we have. Caveats and Dangers =================== Here are caveats for working with this conflict resolution approach. Each sub-section has a "DANGERS" section that outlines what might happen if you ignore the warning. We work from the least danger to the most. Conflict Resolution Is on the Server ------------------------------------ If you are using ZEO or ZRS, be aware that the classes for which you have conflict resolution code *and* the classes of the non-persistent objects they reference must be available to import by the *server* (or ZRS primary). DANGERS: You think you are going to get conflict resolution, but you won't. Ignore `self` ------------- Even though the _p_resolveConflict method has a "self", ignore it. Don't change it. You make changes by returning the state. This is effectively a class method. DANGERS: The changes you make to the instance will be discarded. The instance is not initialized, so other methods that depend on instance attributes will not work. Here's an example of a broken _p_resolveConflict method:: class PCounter2(PCounter): def __init__(self): self.data = [] def _p_resolveConflict(self, oldState, savedState, newState): self.data.append('bad idea') return super(PCounter2, self)._p_resolveConflict( oldState, savedState, newState) .. -> src >>> exec src in ConflictResolution_txt.__dict__ >>> PCounter2 = ConflictResolution_txt.PCounter2 >>> PCounter2.__module__ = 'ConflictResolution_txt' Now we'll prepare for the conflict again. >>> p2_A = conn_A.root()['p2'] = PCounter2() >>> p2_A.value 0 >>> tm_A.commit() >>> trans = tm_B.begin() # sync >>> p2_B = conn_B.root()['p2'] >>> p2_B.value 0 >>> p2_A._p_oid == p2_B._p_oid True And now we will make a conflict. >>> p2_A.inc() >>> p2_A.value 1 >>> p2_B.inc() >>> p2_B.value 1 >>> tm_B.commit() >>> p2_B.value 1 >>> tm_A.commit() # doctest: +ELLIPSIS Traceback (most recent call last): ... ConflictError: database conflict error... oops! >>> tm_A.abort() >>> p2_A.value 1 >>> trans = tm_B.begin() >>> p2_B.value 1 Watch Out for Persistent Objects in the State --------------------------------------------- If the object state has a reference to Persistent objects (instances of classes that inherit from persistent.Persistent) then these references *will not be loaded and are inaccessible*. Instead, persistent objects in the state dictionary are ZODB.ConflictResolution.PersistentReference instances. These objects have the following interface:: class IPersistentReference(zope.interface.Interface): '''public contract for references to persistent objects from an object with conflicts.''' oid = zope.interface.Attribute( 'The oid of the persistent object that this reference represents') database_name = zope.interface.Attribute( '''The name of the database of the reference, *if* different. If not different, None.''') klass = zope.interface.Attribute( '''class meta data. Presence is not reliable.''') weak = zope.interface.Attribute( '''bool: whether this reference is weak''') def __cmp__(other): '''if other is equivalent reference, return 0; else raise ValueError. Equivalent in this case means that oid and database_name are the same. If either is a weak reference, we only support `is` equivalence, and otherwise raise a ValueError even if the datbase_names and oids are the same, rather than guess at the correct semantics. It is impossible to sort reliably, since the actual persistent class may have its own comparison, and we have no idea what it is. We assert that it is reasonably safe to assume that an object is equivalent to itself, but that's as much as we can say. We don't compare on 'is other', despite the PersistentReferenceFactory.data cache, because it is possible to have two references to the same object that are spelled with different data (for instance, one with a class and one without).''' So let's look at one of these. Let's assume we have three, `old`, `saved`, and `new`, each representing a persistent reference to the same object within a _p_resolveConflict call from the oldState, savedState, and newState [#get_persistent_reference]_. They have an oid, `weak` is False, and `database_name` is None. `klass` happens to be set but this is not always the case. >>> isinstance(new.oid, str) True >>> new.weak False >>> print new.database_name None >>> new.klass is PCounter True There are a few subtleties to highlight here. First, notice that the database_name is only present if this is a cross-database reference (see cross-database-references.txt in this directory, and examples below). The database name and oid is sometimes a reasonable way to reliably sort Persistent objects (see zope.app.keyreference, for instance) but if your code compares one PersistentReference with a database_name and another without, you need to refuse to give an answer and raise an exception, because you can't know how the unknown database_name sorts. We already saw a persistent reference with a database_name of None. Now let's suppose `new` is an example of a cross-database reference from a database named '2' [#cross-database]_. >>> new.database_name '2' As seen, the database_name is available for this cross-database reference, and not for others. References to persistent objects, as defined in seialize.py, have other variations, such as weak references, which are handled but not discussed here [#instantiation_test]_ Second, notice the __cmp__ behavior [#cmp_test]_. This is new behavior after ZODB 3.8 and addresses a serious problem for when persistent objects are compared in an _p_resolveConflict, such as that in the ZODB BTrees code. Prior to this change, it was not safe to use Persistent objects as keys in a BTree. You needed to define a __cmp__ for them to be sorted reliably out of the context of conflict resolution, but then during conflict resolution the sorting would be arbitrary, on the basis of the persistent reference's memory location. This could have lead to inconsistent state for BTrees (or BTree module buckets or tree sets or sets). Here's an example of how the new behavior stops potentially incorrect resolution. >>> import BTrees >>> treeset_A = conn_A.root()['treeset'] = BTrees.family32.OI.TreeSet() >>> tm_A.commit() >>> trans = tm_B.begin() # sync >>> treeset_B = conn_B.root()['treeset'] >>> treeset_A.insert(PCounter()) 1 >>> treeset_B.insert(PCounter()) 1 >>> tm_B.commit() >>> tm_A.commit() # doctest: +ELLIPSIS Traceback (most recent call last): ... ConflictError: database conflict error... >>> tm_A.abort() Third, note that, even if the persistent object to which the reference refers changes in the same transaction, the reference is still the same. DANGERS: subtle and potentially serious. Beyond the two subtleties above, which should now be addressed, there is a general problem for objects that are composites of smaller persistent objects--for instance, a BTree, in which the BTree and each bucket is a persistent object; or a zc.queue.CompositePersistentQueue, which is a persistent queue of persistent queues. Consider the following situation. It is actually solved, but it is a concrete example of what might go wrong. A BTree (persistent object) has a two buckets (persistent objects). The second bucket has one persistent object in it. Concurrently, one thread deletes the one object in the second bucket, which causes the BTree to dump the bucket; and another thread puts an object in the second bucket. What happens during conflict resolution? Remember, each persistent object cannot see the other. From the perspective of the BTree object, it has no conflicts: one transaction modified it, causing it to lose a bucket; and the other transaction did not change it. From the perspective of the bucket, one transaction deleted an object and the other added it: it will resolve conflicts and say that the bucket has the new object and not the old one. However, it will be garbage collected, and effectively the addition of the new object will be lost. As mentioned, this story is actually solved for BTrees. As BTrees/MergeTemplate.c explains, whenever savedState or newState for a bucket shows an empty bucket, the code refuses to resolve the conflict: this avoids the situation above. >>> bucket_A = conn_A.root()['bucket'] = BTrees.family32.II.Bucket() >>> bucket_A[0] = 255 >>> tm_A.commit() >>> trans = tm_B.begin() # sync >>> bucket_B = conn_B.root()['bucket'] >>> bucket_B[1] = 254 >>> del bucket_A[0] >>> tm_B.commit() >>> tm_A.commit() # doctest: +ELLIPSIS Traceback (most recent call last): ... ConflictError: database conflict error... >>> tm_A.abort() However, the story highlights the kinds of subtle problems that units made up of multiple composite Persistent objects need to contemplate. Any structure made up of objects that contain persistent objects with conflict resolution code, as a catalog index is made up of multiple BTree Buckets and Sets, each with conflict resolution, needs to think through these kinds of problems or be faced with potential data integrity issues. .. cleanup >>> db.close() >>> db1.close() >>> db2.close() .. ......... .. ..

Lets set up a multi-database with 2 databases: >>> import ZODB.tests.util, transaction, persistent >>> databases = {} >>> db1 = ZODB.tests.util.DB(databases=databases, database_name='1') >>> db2 = ZODB.tests.util.DB(databases=databases, database_name='2') And create a persistent object in the first database: >>> tm = transaction.TransactionManager() >>> conn1 = db1.open(transaction_manager=tm) >>> p1 = MyClass() >>> conn1.root()['p'] = p1 >>> tm.commit() First, we get a connection to the second database. We get the second connection using the first connection's `get_connection` method. This is important. When using multiple databases, we need to make sure we use a consistent set of connections so that the objects in the connection caches are connected in a consistent manner. >>> conn2 = conn1.get_connection('2') Now, we'll create a second persistent object in the second database. We'll have a reference to the first object: >>> p2 = MyClass() >>> conn2.root()['p'] = p2 >>> p2.p1 = p1 >>> tm.commit() Now, let's open a separate connection to database 2. We use it to read `p2`, use `p2` to get to `p1`, and verify that it is in database 1: >>> conn = db2.open() >>> p2x = conn.root()['p'] >>> p1x = p2x.p1 >>> p2x is p2, p2x._p_oid == p2._p_oid, p2x._p_jar.db() is db2 (False, True, True) >>> p1x is p1, p1x._p_oid == p1._p_oid, p1x._p_jar.db() is db1 (False, True, True) It isn't valid to create references outside a multi database: >>> db3 = ZODB.tests.util.DB() >>> conn3 = db3.open(transaction_manager=tm) >>> p3 = MyClass() >>> conn3.root()['p'] = p3 >>> tm.commit() >>> p2.p3 = p3 >>> tm.commit() # doctest: +NORMALIZE_WHITESPACE +ELLIPSIS Traceback (most recent call last): ... InvalidObjectReference: ('Attempt to store an object from a foreign database connection', , ) >>> tm.abort() Databases for new objects ------------------------- Objects are normally added to a database by making them reachable from an object already in the database. This is unambiguous when there is only one database. With multiple databases, it is not so clear what happens. Consider: >>> p4 = MyClass() >>> p1.p4 = p4 >>> p2.p4 = p4 In this example, the new object is reachable from both `p1` in database 1 and `p2` in database 2. If we commit, which database should `p4` end up in? This sort of ambiguity could lead to subtle bugs. For that reason, an error is generated if we commit changes when new objects are reachable from multiple databases: >>> tm.commit() # doctest: +NORMALIZE_WHITESPACE +ELLIPSIS Traceback (most recent call last): ... InvalidObjectReference: ("A new object is reachable from multiple databases. Won't try to guess which one was correct!", , ) >>> tm.abort() To resolve this ambiguity, we can commit before an object becomes reachable from multiple databases. >>> p4 = MyClass() >>> p1.p4 = p4 >>> tm.commit() >>> p2.p4 = p4 >>> tm.commit() >>> p4._p_jar.db().database_name '1' This doesn't work with a savepoint: >>> p5 = MyClass() >>> p1.p5 = p5 >>> s = tm.savepoint() >>> p2.p5 = p5 >>> tm.commit() # doctest: +NORMALIZE_WHITESPACE +ELLIPSIS Traceback (most recent call last): ... InvalidObjectReference: ("A new object is reachable from multiple databases. Won't try to guess which one was correct!", , ) >>> tm.abort() (Maybe it should.) We can disambiguate this situation by using the connection add method to explicitly say what database an object belongs to: >>> p5 = MyClass() >>> p1.p5 = p5 >>> p2.p5 = p5 >>> conn1.add(p5) >>> tm.commit() >>> p5._p_jar.db().database_name '1' This the most explicit and thus the best way, when practical, to avoid the ambiguity. Dissallowing implicit cross-database references ----------------------------------------------- The database contructor accepts a xrefs keyword argument that defaults to True. If False is passed, the implicit cross database references are disallowed. (Note that currently, implicit cross references are the only kind of cross references allowed.) >>> databases = {} >>> db1 = ZODB.tests.util.DB(databases=databases, database_name='1') >>> db2 = ZODB.tests.util.DB(databases=databases, database_name='2', ... xrefs=False) In this example, we allow cross-references from db1 to db2, but not the other way around. >>> c1 = db1.open() >>> c2 = c1.get_connection('2') >>> c1.root.x = c2.root() >>> transaction.commit() >>> c2.root.x = c1.root() >>> transaction.commit() # doctest: +NORMALIZE_WHITESPACE +ELLIPSIS Traceback (most recent call last): ... InvalidObjectReference: ("Database '2' doesn't allow implicit cross-database references", , {'x': {}}) >>> transaction.abort() NOTE ---- This implementation is incomplete. It allows creating and using cross-database references, however, there are a number of facilities missing: cross-database garbage collection Garbage collection is done on a database by database basis. If an object on a database only has references to it from other databases, then the object will be garbage collected when its database is packed. The cross-database references to it will be broken. cross-database undo Undo is only applied to a single database. Fixing this for multiple databases is going to be extremely difficult. Undo currently poses consistency problems, so it is not (or should not be) widely used. Cross-database aware (tolerant) export/import The export/import facility needs to be aware, at least, of cross-database references. zope2.13-2.13.21/source/ZODB3/src/ZODB/tests/0000755000175000017500000000000012214017464016750 5ustar arnauarnauzope2.13-2.13.21/source/ZODB3/src/ZODB/tests/testConnectionSavepoint.txt0000644000175000017500000001171612214017464024407 0ustar arnauarnau========== Savepoints ========== Savepoints provide a way to save to disk intermediate work done during a transaction allowing: - partial transaction (subtransaction) rollback (abort) - state of saved objects to be freed, freeing on-line memory for other uses Savepoints make it possible to write atomic subroutines that don't make top-level transaction commitments. Applications ------------ To demonstrate how savepoints work with transactions, we'll show an example. >>> import ZODB.tests.util >>> db = ZODB.tests.util.DB() >>> connection = db.open() >>> root = connection.root() >>> root['name'] = 'bob' As with other data managers, we can commit changes: >>> import transaction >>> transaction.commit() >>> root['name'] 'bob' and abort changes: >>> root['name'] = 'sally' >>> root['name'] 'sally' >>> transaction.abort() >>> root['name'] 'bob' Now, let's look at an application that manages funds for people. It allows deposits and debits to be entered for multiple people. It accepts a sequence of entries and generates a sequence of status messages. For each entry, it applies the change and then validates the user's account. If the user's account is invalid, we roll back the change for that entry. The success or failure of an entry is indicated in the output status. First we'll initialize some accounts: >>> root['bob-balance'] = 0.0 >>> root['bob-credit'] = 0.0 >>> root['sally-balance'] = 0.0 >>> root['sally-credit'] = 100.0 >>> transaction.commit() Now, we'll define a validation function to validate an account: >>> def validate_account(name): ... if root[name+'-balance'] + root[name+'-credit'] < 0: ... raise ValueError('Overdrawn', name) And a function to apply entries. If the function fails in some unexpected way, it rolls back all of its changes and prints the error: >>> def apply_entries(entries): ... savepoint = transaction.savepoint() ... try: ... for name, amount in entries: ... entry_savepoint = transaction.savepoint() ... try: ... root[name+'-balance'] += amount ... validate_account(name) ... except ValueError, error: ... entry_savepoint.rollback() ... print 'Error', str(error) ... else: ... print 'Updated', name ... except Exception, error: ... savepoint.rollback() ... print 'Unexpected exception', error Now let's try applying some entries: >>> apply_entries([ ... ('bob', 10.0), ... ('sally', 10.0), ... ('bob', 20.0), ... ('sally', 10.0), ... ('bob', -100.0), ... ('sally', -100.0), ... ]) Updated bob Updated sally Updated bob Updated sally Error ('Overdrawn', 'bob') Updated sally >>> root['bob-balance'] 30.0 >>> root['sally-balance'] -80.0 If we provide entries that cause an unexpected error: >>> apply_entries([ ... ('bob', 10.0), ... ('sally', 10.0), ... ('bob', '20.0'), ... ('sally', 10.0), ... ]) Updated bob Updated sally Unexpected exception unsupported operand type(s) for +=: 'float' and 'str' Because the apply_entries used a savepoint for the entire function, it was able to rollback the partial changes without rolling back changes made in the previous call to ``apply_entries``: >>> root['bob-balance'] 30.0 >>> root['sally-balance'] -80.0 If we now abort the outer transactions, the earlier changes will go away: >>> transaction.abort() >>> root['bob-balance'] 0.0 >>> root['sally-balance'] 0.0 Savepoint invalidation ---------------------- A savepoint can be used any number of times: >>> root['bob-balance'] = 100.0 >>> root['bob-balance'] 100.0 >>> savepoint = transaction.savepoint() >>> root['bob-balance'] = 200.0 >>> root['bob-balance'] 200.0 >>> savepoint.rollback() >>> root['bob-balance'] 100.0 >>> savepoint.rollback() # redundant, but should be harmless >>> root['bob-balance'] 100.0 >>> root['bob-balance'] = 300.0 >>> root['bob-balance'] 300.0 >>> savepoint.rollback() >>> root['bob-balance'] 100.0 However, using a savepoint invalidates any savepoints that come after it: >>> root['bob-balance'] = 200.0 >>> root['bob-balance'] 200.0 >>> savepoint1 = transaction.savepoint() >>> root['bob-balance'] = 300.0 >>> root['bob-balance'] 300.0 >>> savepoint2 = transaction.savepoint() >>> savepoint.rollback() >>> root['bob-balance'] 100.0 >>> savepoint2.rollback() Traceback (most recent call last): ...

The original proposal is in the fishbowl: http://www.zope.org/Wikis/ZODB/MultiDatabases/ It was implemented during the PyCon 2005 sprints, but in a simpler form, by Jim Fulton, Christian Theune, and Tim Peters. Overview: No private attributes were added, and one new method was introduced. ``DB``: - a new ``.database_name`` attribute holds the name of this database. - a new ``.databases`` attribute maps from database name to ``DB`` object; all databases in a multi-database collection share the same ``.databases`` object - the ``DB`` constructor has new optional arguments with the same names (``database_name=`` and ``databases=``). ``Connection``: - a new ``.connections`` attribute maps from database name to a ``Connection`` for the database with that name; the ``.connections`` mapping object is also shared among databases in a collection. - a new ``.get_connection(database_name)`` method returns a ``Connection`` for a database in the collection; if a connection is already open, it's returned (this is the value ``.connections[database_name]``), else a new connection is opened (and stored as ``.connections[database_name]``) Creating a multi-database starts with creating a named ``DB``: >>> from ZODB.tests.test_storage import MinimalMemoryStorage >>> from ZODB import DB >>> dbmap = {} >>> db = DB(MinimalMemoryStorage(), database_name='root', databases=dbmap) The database name is accessible afterwards and in a newly created collection: >>> db.database_name 'root' >>> db.databases # doctest: +ELLIPSIS {'root': } >>> db.databases is dbmap True Adding another database to the collection works like this: >>> db2 = DB(MinimalMemoryStorage(), ... database_name='notroot', ... databases=dbmap) The new ``db2`` now shares the ``databases`` dictionary with db and has two entries: >>> db2.databases is db.databases is dbmap True >>> len(db2.databases) 2 >>> names = dbmap.keys(); names.sort(); print names ['notroot', 'root'] It's an error to try to insert a database with a name already in use: >>> db3 = DB(MinimalMemoryStorage(), ... database_name='root', ... databases=dbmap) Traceback (most recent call last): ... ValueError: database_name 'root' already in databases Because that failed, ``db.databases`` wasn't changed: >>> len(db.databases) # still 2 2 You can (still) get a connection to a database this way: >>> import transaction >>> tm = transaction.TransactionManager() >>> cn = db.open(transaction_manager=tm) >>> cn # doctest: +ELLIPSIS This is the only connection in this collection right now: >>> cn.connections # doctest: +ELLIPSIS {'root': } Getting a connection to a different database from an existing connection in the same database collection (this enables 'connection binding' within a given thread/transaction/context ...): >>> cn2 = cn.get_connection('notroot') >>> cn2 # doctest: +ELLIPSIS The second connection gets the same transaction manager as the first: >>> cn2.transaction_manager is tm True Now there are two connections in that collection: >>> cn2.connections is cn.connections True >>> len(cn2.connections) 2 >>> names = cn.connections.keys(); names.sort(); print names ['notroot', 'root'] So long as this database group remains open, the same ``Connection`` objects are returned: >>> cn.get_connection('root') is cn True >>> cn.get_connection('notroot') is cn2 True >>> cn2.get_connection('root') is cn True >>> cn2.get_connection('notroot') is cn2 True Of course trying to get a connection for a database not in the group raises an exception: >>> cn.get_connection('no way') Traceback (most recent call last): ... KeyError: 'no way' Clean up: >>> for a_db in dbmap.values(): ... a_db.close() Configuration from File ----------------------- The database name can also be specified in a config file, starting in ZODB 3.6: >>> from ZODB.config import databaseFromString >>> config = """ ... ... ... database-name this_is_the_name ... ... """ >>> db = databaseFromString(config) >>> print db.database_name this_is_the_name >>> db.databases.keys() ['this_is_the_name'] However, the ``.databases`` attribute cannot be configured from file. It can be passed to the `ZConfig` factory. I'm not sure of the clearest way to test that here; this is ugly: >>> from ZODB.config import getDbSchema >>> import ZConfig >>> from cStringIO import StringIO Derive a new `config2` string from the `config` string, specifying a different database_name: >>> config2 = config.replace("this_is_the_name", "another_name") Now get a `ZConfig` factory from `config2`: >>> f = StringIO(config2) >>> zconfig, handle = ZConfig.loadConfigFile(getDbSchema(), f) >>> factory = zconfig.database The desired ``databases`` mapping can be passed to this factory: >>> db2 = factory[0].open(databases=db.databases) >>> print db2.database_name # has the right name another_name >>> db.databases is db2.databases # shares .databases with `db` True >>> all = db2.databases.keys() >>> all.sort() >>> all # and db.database_name & db2.database_name are the keys ['another_name', 'this_is_the_name'] Cleanup. >>> db.close() >>> db2.close() zope2.13-2.13.21/source/ZODB3/src/ZODB/tests/test_doctest_files.py0000644000175000017500000000335612214017464023217 0ustar arnauarnau############################################################################## # # Copyright (c) 2004 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

The current default layout is called `bushy`. The original blob implementation used a layout that we now call `lawn` and which is still available for backwards compatibility. Layouts implement two methods: one for computing a relative path for an OID and one for turning a relative path back into an OID. Our terminology is roughly the same as used in `DirectoryStorage`. The `bushy` layout ================== The bushy layout splits the OID into the 8 byte parts, reverses them and creates one directory level for each part, named by the hexlified representation of the byte value. This results in 8 levels of directories, the leaf directories being used for the revisions of the blobs and at most 256 entries per directory level: >>> from ZODB.blob import BushyLayout >>> bushy = BushyLayout() >>> bushy.oid_to_path('\x00\x00\x00\x00\x00\x00\x00\x00') '0x00/0x00/0x00/0x00/0x00/0x00/0x00/0x00' >>> bushy.oid_to_path('\x00\x00\x00\x00\x00\x00\x00\x01') '0x00/0x00/0x00/0x00/0x00/0x00/0x00/0x01' >>> import os >>> bushy.path_to_oid(os.path.join( ...

This has some limitations on various file systems like performance penalties or the inability to store more than a given number of blobs at the same time (e.g. 32k on ext3). >>> from ZODB.blob import LawnLayout >>> lawn = LawnLayout() >>> lawn.oid_to_path('\x00\x00\x00\x00\x00\x00\x00\x00') '0x00' >>> lawn.oid_to_path('\x00\x00\x00\x00\x00\x00\x00\x01') '0x01' >>> lawn.path_to_oid('0x01') '\x00\x00\x00\x00\x00\x00\x00\x01' Paths that do not represent an OID will cause a ValueError: >>> lawn.path_to_oid('tmp') Traceback (most recent call last): ValueError: Not a valid OID path: `tmp` >>> lawn.path_to_oid('') Traceback (most recent call last): ValueError: Not a valid OID path: `` Auto-detecting the layout of a directory ======================================== To allow easier migration, we provide an auto-detection feature that analyses a blob directory and decides for a strategy to use. In general it prefers to choose the `bushy` layout, except if it determines that the directory has already been used to create a lawn structure. >>> from ZODB.blob import auto_layout_select 1. Non-existing directories will trigger a bushy layout: >>> import os, shutil >>> auto_layout_select('blobs') 'bushy' 2. Empty directories will trigger a bushy layout too: >>> os.mkdir('blobs') >>> auto_layout_select('blobs') 'bushy' 3. If the directory contains a marker for the strategy it will be used: >>> from ZODB.blob import LAYOUT_MARKER >>> import os.path >>> open(os.path.join('blobs', LAYOUT_MARKER), 'wb').write('bushy') >>> auto_layout_select('blobs') 'bushy' >>> open(os.path.join('blobs', LAYOUT_MARKER), 'wb').write('lawn') >>> auto_layout_select('blobs') 'lawn' >>> shutil.rmtree('blobs') 4. If the directory does not contain a marker but other files that are not hidden, we assume that it was created with an earlier version of the blob implementation and uses our `lawn` layout: >>> os.mkdir('blobs') >>> open(os.path.join('blobs', '0x0101'), 'wb').write('foo') >>> auto_layout_select('blobs') 'lawn' >>> shutil.rmtree('blobs') 5. If the directory contains only hidden files, use the bushy layout: >>> os.mkdir('blobs') >>> open(os.path.join('blobs', '.svn'), 'wb').write('blah') >>> auto_layout_select('blobs') 'bushy' >>> shutil.rmtree('blobs') Directory layout markers ======================== When the file system helper (FSH) is asked to create the directory structure, it will leave a marker with the choosen layout if no marker exists yet: >>> from ZODB.blob import FilesystemHelper >>> blobs = 'blobs' >>> fsh = FilesystemHelper(blobs) >>> fsh.layout_name 'bushy' >>> fsh.create() >>> open(os.path.join(blobs, LAYOUT_MARKER), 'rb').read() 'bushy' If the FSH finds a marker, then it verifies whether its content matches the strategy that was chosen. It will raise an exception if we try to work with a directory that has a different marker than the chosen strategy: >>> fsh = FilesystemHelper(blobs, 'lawn') >>> fsh.layout_name 'lawn' >>> fsh.create() # doctest: +ELLIPSIS Traceback (most recent call last): ValueError: Directory layout `lawn` selected for blob directory .../blobs/, but marker found for layout `bushy` >>> rmtree(blobs) This function interacts with the automatic detection in the way, that an unmarked directory will be marked the first time when it is auto-guessed and the marker will be used in the future: >>> import ZODB.FileStorage >>> from ZODB.blob import BlobStorage >>> datafs = 'data.fs' >>> base_storage = ZODB.FileStorage.FileStorage(datafs) >>> os.mkdir(blobs) >>> open(os.path.join(blobs, 'foo'), 'wb').write('foo') >>> blob_storage = BlobStorage(blobs, base_storage) >>> blob_storage.fshelper.layout_name 'lawn' >>> open(os.path.join(blobs, LAYOUT_MARKER), 'rb').read() 'lawn' >>> blob_storage = BlobStorage('blobs', base_storage, layout='bushy') ... # doctest: +ELLIPSIS Traceback (most recent call last): ValueError: Directory layout `bushy` selected for blob directory .../blobs/, but marker found for layout `lawn` >>> base_storage.close() >>> rmtree('blobs') Migrating between directory layouts =================================== A script called `migrateblobs.py` is distributed with the ZODB for offline migration capabilities between different directory layouts. It can migrate any blob directory layout to any other layout. It leaves the original blob directory untouched (except from eventually creating a temporary directory and the storage layout marker). The migration is accessible as a library function: >>> from ZODB.scripts.migrateblobs import migrate Create a `lawn` directory structure and migrate it to the new `bushy` one: >>> from ZODB.blob import FilesystemHelper >>> d = 'd' >>> os.mkdir(d) >>> old = os.path.join(d, 'old') >>> old_fsh = FilesystemHelper(old, 'lawn') >>> old_fsh.create() >>> blob1 = old_fsh.getPathForOID(7039, create=True) >>> blob2 = old_fsh.getPathForOID(10, create=True) >>> blob3 = old_fsh.getPathForOID(7034, create=True) >>> open(os.path.join(blob1, 'foo'), 'wb').write('foo') >>> open(os.path.join(blob1, 'foo2'), 'wb').write('bar') >>> open(os.path.join(blob2, 'foo3'), 'wb').write('baz') >>> open(os.path.join(blob2, 'foo4'), 'wb').write('qux') >>> open(os.path.join(blob3, 'foo5'), 'wb').write('quux') >>> open(os.path.join(blob3, 'foo6'), 'wb').write('corge') Committed blobs have their permissions set to 000 The migration function is called with the old and the new path and the layout that shall be used for the new directory: >>> bushy = os.path.join(d, 'bushy') >>> migrate(old, bushy, 'bushy') # doctest: +ELLIPSIS +NORMALIZE_WHITESPACE Migrating blob data from `.../old` (lawn) to `.../bushy` (bushy) OID: 0x0a - 2 files OID: 0x1b7a - 2 files OID: 0x1b7f - 2 files The new directory now contains the same files in different directories, but with the same sizes and permissions: >>> lawn_files = {} >>> for base, dirs, files in os.walk(old): ... for file_name in files: ... lawn_files[file_name] = os.path.join(base, file_name) >>> bushy_files = {} >>> for base, dirs, files in os.walk(bushy): ... for file_name in files: ... bushy_files[file_name] = os.path.join(base, file_name) >>> len(lawn_files) == len(bushy_files) True >>> for file_name, lawn_path in sorted(lawn_files.items()): ... if file_name == '.layout': ... continue ... lawn_stat = os.stat(lawn_path) ... bushy_path = bushy_files[file_name] ... bushy_stat = os.stat(bushy_path) ... print lawn_path, '-->', bushy_path ... if ((lawn_stat.st_mode, lawn_stat.st_size) != ...

Normally when an object is read from the storage, its most recent revision is read. Under MVCC, an older revision may be read so that the transaction sees a consistent view of the database. ZODB guarantees execution-time consistency: A single transaction will always see a consistent view of the database while it is executing. If transaction A is running, has already read an object O1, and a different transaction B modifies object O2, then transaction A can no longer read the current revision of O2. It must either read the version of O2 that is consistent with O1 or raise a ReadConflictError. When MVCC is in use, A will do the former. This note includes doctests that explain how MVCC is implemented (and test that the implementation is correct). The tests use a MinimalMemoryStorage that implements MVCC support, but not much else. >>> from ZODB.tests.test_storage import MinimalMemoryStorage >>> from ZODB import DB >>> db = DB(MinimalMemoryStorage()) We will use two different connections with different transaction managers to make sure that the connections act independently, even though they'll be run from a single thread. >>> import transaction >>> tm1 = transaction.TransactionManager() >>> cn1 = db.open(transaction_manager=tm1) The test will just use some MinPO objects. The next few lines just setup an initial database state. >>> from ZODB.tests.MinPO import MinPO >>> r = cn1.root() >>> r["a"] = MinPO(1) >>> r["b"] = MinPO(1) >>> tm1.get().commit() Now open a second connection. >>> tm2 = transaction.TransactionManager() >>> cn2 = db.open(transaction_manager=tm2) Connection high-water mark -------------------------- The ZODB Connection tracks a transaction high-water mark, which bounds the latest transaction id that can be read by the current transaction and still present a consistent view of the database. Transactions with ids up to but not including the high-water mark are OK to read. When a transaction commits, the database sends invalidations to all the other connections; the invalidation contains the transaction id and the oids of modified objects. The Connection stores the high-water mark in _txn_time, which is set to None until an invalidation arrives. >>> cn = db.open() >>> print cn._txn_time None >>> cn.invalidate(100, dict.fromkeys([1, 2])) >>> cn._txn_time 100 >>> cn.invalidate(200, dict.fromkeys([1, 2])) >>> cn._txn_time 100 A connection's high-water mark is set to the transaction id taken from the first invalidation processed by the connection. Transaction ids are monotonically increasing, so the first one seen during the current transaction remains the high-water mark for the duration of the transaction. We'd like simple abort and commit calls to make txn boundaries, but that doesn't work unless an object is modified. sync() will abort a transaction and process invalidations. >>> cn.sync() >>> print cn._txn_time # the high-water mark got reset to None None Basic functionality ------------------- The next bit of code includes a simple MVCC test. One transaction will modify "a." The other transaction will then modify "b" and commit. >>> r1 = cn1.root() >>> r1["a"].value = 2 >>> tm1.get().commit() >>> txn = db.lastTransaction() The second connection has its high-water mark set now. >>> cn2._txn_time == txn True It is safe to read "b," because it was not modified by the concurrent transaction. >>> r2 = cn2.root() >>> r2["b"]._p_serial < cn2._txn_time True >>> r2["b"].value 1 >>> r2["b"].value = 2 It is not safe, however, to read the current revision of "a" because it was modified at the high-water mark. If we read it, we'll get a non-current version. >>> r2["a"].value 1 >>> r2["a"]._p_serial < cn2._txn_time True We can confirm that we have a non-current revision by asking the storage. >>> db.storage.isCurrent(r2["a"]._p_oid, r2["a"]._p_serial) False It's possible to modify "a", but we get a conflict error when we commit the transaction. >>> r2["a"].value = 3 >>> tm2.get().commit() Traceback (most recent call last): ... ConflictError: database conflict error (oid 0x01, class ZODB.tests.MinPO.MinPO) >>> tm2.get().abort() This example will demonstrate that we can commit a transaction if we only modify current revisions. >>> print cn2._txn_time None >>> r1 = cn1.root() >>> r1["a"].value = 3 >>> tm1.get().commit() >>> txn = db.lastTransaction() >>> cn2._txn_time == txn True >>> r2["b"].value = r2["a"].value + 1 >>> r2["b"].value 3 >>> tm2.get().commit() >>> print cn2._txn_time None Object cache ------------ A Connection keeps objects in its cache so that multiple database references will always point to the same Python object. At transaction boundaries, objects modified by other transactions are ghostified so that the next transaction doesn't see stale state. We need to be sure the non-current objects loaded by MVCC are always ghosted. It should be trivial, because MVCC is only used when an invalidation has been received for an object. First get the database back in an initial state. >>> cn1.sync() >>> r1["a"].value = 0 >>> r1["b"].value = 0 >>> tm1.get().commit() >>> cn2.sync() >>> r2["a"].value 0 >>> r2["b"].value = 1 >>> tm2.get().commit() >>> r1["b"].value 0 >>> cn1.sync() # cn2 modified 'b', so cn1 should get a ghost for b >>> r1["b"]._p_state # -1 means GHOST -1 Closing the connection, committing a transaction, and aborting a transaction, should all have the same effect on non-current objects in cache. >>> def testit(): ... cn1.sync() ... r1["a"].value = 0 ... r1["b"].value = 0 ... tm1.get().commit() ... cn2.sync() ... r2["b"].value = 1 ... tm2.get().commit() >>> testit() >>> r1["b"]._p_state # 0 means UPTODATE, although note it's an older revision 0 >>> r1["b"].value 0 >>> r1["a"].value = 1 >>> tm1.get().commit() >>> r1["b"]._p_state -1 When a connection is closed, it is saved by the database. It will be reused by the next open() call (along with its object cache). >>> testit() >>> r1["a"].value = 1 >>> tm1.get().abort() >>> cn1.close() >>> cn3 = db.open() >>> cn1 is cn3 True >>> r1 = cn1.root() Although "b" is a ghost in cn1 at this point (because closing a connection has the same effect on non-current objects in the connection's cache as committing a transaction), not every object is a ghost. The root was in the cache and was current, so our first reference to it doesn't return a ghost. >>> r1._p_state # UPTODATE 0 >>> r1["b"]._p_state # GHOST -1 Interaction with Savepoints --------------------------- Basically, making a savepoint shouldn't have any effect on what a thread sees. Before ZODB 3.4.1, the internal TmpStore used when savepoints are pending didn't delegate all the methods necessary to make this work, so we'll do a quick test of that here. First get a clean slate: >>> cn1.close(); cn2.close() >>> cn1 = db.open(transaction_manager=tm1) >>> r1 = cn1.root() >>> r1["a"].value = 0 >>> r1["b"].value = 1 >>> tm1.commit() Now modify "a", but not "b", and make a savepoint. >>> r1["a"].value = 42 >>> sp = cn1.savepoint() Over in the other connection, modify "b" and commit it. This makes the first connection's state for b "old". >>> cn2 = db.open(transaction_manager=tm2) >>> r2 = cn2.root() >>> r2["a"].value, r2["b"].value # shouldn't see the change to "a" (0, 1) >>> r2["b"].value = 43 >>> tm2.commit() >>> r2["a"].value, r2["b"].value (0, 43) Now deactivate "b" in the first connection, and (re)fetch it. The first connection should still see 1, due to MVCC, but to get this old state TmpStore needs to handle the loadBefore() method. >>> r1["b"]._p_deactivate() Before 3.4.1, the next line died with AttributeError: TmpStore instance has no attribute 'loadBefore' >>> r1["b"]._p_state # ghost -1 >>> r1["b"].value 1 Just for fun, finish the commit and make sure both connections see the same things now. >>> tm1.commit() >>> cn1.sync(); cn2.sync() >>> r1["a"].value, r1["b"].value (42, 43) >>> r2["a"].value, r2["b"].value (42, 43) Late invalidation ----------------- The combination of ZEO and MVCC adds more complexity. Since invalidations are delivered asynchronously by ZEO, it is possible for an invalidation to arrive just after a request to load the invalidated object is sent. The connection can't use the just-loaded data, because the invalidation arrived first. The complexity for MVCC is that it must check for invalidated objects after it has loaded them, just in case. Rather than add all the complexity of ZEO to these tests, the MinimalMemoryStorage has a hook. We'll write a subclass that will deliver an invalidation when it loads an object. The hook allows us to test the Connection code. >>> class TestStorage(MinimalMemoryStorage): ... def __init__(self): ... self.hooked = {} ... self.count = 0 ... super(TestStorage, self).__init__() ... def registerDB(self, db): ... self.db = db ... def hook(self, oid, tid, version): ... if oid in self.hooked: ... self.db.invalidate(tid, {oid:1}) ... self.count += 1 We can execute this test with a single connection, because we're synthesizing the invalidation that is normally generated by the second connection. We need to create two revisions so that there is a non-current revision to load. >>> ts = TestStorage() >>> db = DB(ts) >>> cn1 = db.open(transaction_manager=tm1) >>> r1 = cn1.root() >>> r1["a"] = MinPO(0) >>> r1["b"] = MinPO(0) >>> tm1.get().commit() >>> r1["b"].value = 1 >>> tm1.get().commit() >>> cn1.cacheMinimize() # makes everything in cache a ghost >>> oid = r1["b"]._p_oid >>> ts.hooked[oid] = 1 Once the oid is hooked, an invalidation will be delivered the next time it is activated. The code below activates the object, then confirms that the hook worked and that the old state was retrieved. >>> oid in cn1._invalidated False >>> r1["b"]._p_state -1 >>> r1["b"]._p_activate() >>> oid in cn1._invalidated True >>> ts.count 1 >>> r1["b"].value 0 No earlier revision available ----------------------------- We'll reuse the code from the example above, except that there will only be a single revision of "b." As a result, the attempt to activate "b" will result in a ReadConflictError. >>> ts = TestStorage() >>> db = DB(ts) >>> cn1 = db.open(transaction_manager=tm1) >>> r1 = cn1.root() >>> r1["a"] = MinPO(0) >>> r1["b"] = MinPO(0) >>> tm1.get().commit() >>> cn1.cacheMinimize() # makes everything in cache a ghost >>> oid = r1["b"]._p_oid >>> ts.hooked[oid] = 1 Again, once the oid is hooked, an invalidation will be delivered the next time it is activated. The code below activates the object, but unlike the section above, this is no older state to retrieve. >>> oid in cn1._invalidated False >>> r1["b"]._p_state -1 >>> r1["b"]._p_activate() Traceback (most recent call last): ...

The decision depends on whether the blob is already stored in a database or not. Case 1: Blobs that are not in a database yet ============================================ Let's create a new blob and open it for writing:: >>> from ZODB.blob import Blob >>> b = Blob() >>> w = b.open('w') The created file is in the default temporary directory:: >>> import tempfile >>> w.name.startswith(tempfile.gettempdir()) True >>> w.close() Case 2: Blobs that are in a database ==================================== For this case we instanciate a blob and add it to a database immediately. First, we need a datatabase with blob support:: >>> from ZODB.MappingStorage import MappingStorage >>> from ZODB.blob import BlobStorage >>> from ZODB.DB import DB >>> import os.path >>> base_storage = MappingStorage('test') >>> blob_dir = os.path.abspath('blobs') >>> blob_storage = BlobStorage(blob_dir, base_storage) >>> database = DB(blob_storage) Now we create a blob and put it in the database. After that we open it for writing and expect the file to be in the blob temporary directory:: >>> blob = Blob() >>> connection = database.open() >>> connection.add(blob) >>> w = blob.open('w') >>> w.name.startswith(os.path.join(blob_dir, 'tmp')) True >>> w.close() zope2.13-2.13.21/source/ZODB3/src/ZODB/tests/Synchronization.py0000644000175000017500000001026312214017464022525 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

The Synchronization spec http://www.zope.org/Documentation/Developer/Models/ZODB/ ZODB_Architecture_Storage_Interface_State_Synchronization_Diag.html It specifies two states committing and non-committing. A storage starts in the non-committing state. tpc_begin() transfers to the committting state; tpc_abort() and tpc_finish() transfer back to non-committing. Several other methods are only allowed in one state or another. Many methods allowed only in the committing state require that they apply to the currently committing transaction. The spec is silent on a variety of methods that don't appear to modify the state, e.g. load(), undoLog(), pack(). It's unclear whether there is a separate set of synchronization rules that apply to these methods or if the synchronization is implementation dependent, i.e. only what is need to guarantee a corrected implementation. The synchronization spec is also silent on whether there is any contract implied with the caller. If the storage can assume that a single client is single-threaded and that it will not call, e.g., store() until after it calls tpc_begin(), the implementation can be substantially simplified. New and/or unspecified methods: tpc_vote(): handled like tpc_abort undo(): how's that handled? Methods that have nothing to do with committing/non-committing: load(), loadSerial(), getName(), getSize(), __len__(), history(), undoLog(), pack(). Specific questions: The spec & docs say that undo() takes three arguments, the second being a transaction. If the specified arg isn't the current transaction, the undo() should raise StorageTransactionError. This isn't implemented anywhere. It looks like undo can be called at anytime. FileStorage does not allow undo() during a pack. How should this be tested? Is it a general restriction?

So long as we keep opening new connections, and keep them alive, all connections returned are distinct: >>> st = Storage() >>> db = DB(st) >>> c1 = db.open() >>> c2 = db.open() >>> c3 = db.open() >>> c1 is c2 or c1 is c3 or c2 is c3 False Let's put some markers on the connections, so we can identify these specific objects later: >>> c1.MARKER = 'c1' >>> c2.MARKER = 'c2' >>> c3.MARKER = 'c3' Now explicitly close c1 and c2: >>> c1.close() >>> c2.close() Reaching into the internals, we can see that db's connection pool now has two connections available for reuse, and knows about three connections in all: >>> pool = db.pool >>> len(pool.available) 2 >>> len(pool.all) 3 Since we closed c2 last, it's at the top of the available stack, so will be reused by the next open(): >>> c1 = db.open() >>> c1.MARKER 'c2' >>> len(pool.available), len(pool.all) (1, 3) >>> c3.close() # now the stack has c3 on top, then c1 >>> c2 = db.open() >>> c2.MARKER 'c3' >>> len(pool.available), len(pool.all) (1, 3) >>> c3 = db.open() >>> c3.MARKER 'c1' >>> len(pool.available), len(pool.all) (0, 3) It's a bit more complicated though. The connection pool tries to keep connections with larger caches at the top of the stack. It does this by having connections with smaller caches "sink" below connections with larger caches when they are closed. To see this, we'll add some objects to the caches: >>> for i in range(10): ... c1.root()[i] = c1.root().__class__() >>> import transaction >>> transaction.commit() >>> c1._cache.cache_non_ghost_count 11 >>> for i in range(5): ... _ = len(c2.root()[i]) >>> c2._cache.cache_non_ghost_count 6 Now, we'll close the connections and get them back: >>> c1.close() >>> c2.close() >>> c3.close() We closed c3 last, but c1 is the biggest, so we get c1 on the next open: >>> db.open() is c1 True Similarly, c2 is the next buggest, so we get that next: >>> db.open() is c2 True and finally c3: >>> db.open() is c3 True What about the 3 in pool.all? We've seen that closing connections doesn't reduce pool.all, and it would be bad if DB kept connections alive forever. In fact pool.all is a "weak set" of connections -- it holds weak references to connections. That alone doesn't keep connection objects alive. The weak set allows DB's statistics methods to return info about connections that are still alive. >>> len(db.cacheDetailSize()) # one result for each connection's cache 3 If a connection object is abandoned (it becomes unreachable), then it will vanish from pool.all automatically. However, connections are involved in cycles, so exactly when a connection vanishes from pool.all isn't predictable. It can be forced by running gc.collect(): >>> import gc >>> dummy = gc.collect() >>> len(pool.all) 3 >>> c3 = None >>> dummy = gc.collect() # removes c3 from pool.all >>> len(pool.all) 2 Note that c3 is really gone; in particular it didn't get added back to the stack of available connections by magic: >>> len(pool.available) 0 Nothing in that last block should have logged any msgs: >>> handler.records [] If "too many" connections are open, then closing one may kick an older closed one out of the available connection stack. >>> st.close() >>> st = Storage() >>> db = DB(st, pool_size=3) >>> conns = [db.open() for dummy in range(6)] >>> len(handler.records) # 3 warnings for the "excess" connections 3 >>> pool = db.pool >>> len(pool.available), len(pool.all) (0, 6) Let's mark them: >>> for i, c in enumerate(conns): ... c.MARKER = i Closing connections adds them to the stack: >>> for i in range(3): ... conns[i].close() >>> len(pool.available), len(pool.all) (3, 6) >>> del conns[:3] # leave the ones with MARKERs 3, 4 and 5 Closing another one will purge the one with MARKER 0 from the stack (since it was the first added to the stack): >>> [c.MARKER for (t, c) in pool.available] [0, 1, 2] >>> conns[0].close() # MARKER 3 >>> len(pool.available), len(pool.all) (3, 5) >>> [c.MARKER for (t, c) in pool.available] [1, 2, 3] Similarly for the other two: >>> conns[1].close(); conns[2].close() >>> len(pool.available), len(pool.all) (3, 3) >>> [c.MARKER for (t, c) in pool.available] [3, 4, 5] Reducing the pool size may also purge the oldest closed connections: >>> db.setPoolSize(2) # gets rid of MARKER 3 >>> len(pool.available), len(pool.all) (2, 2) >>> [c.MARKER for (t, c) in pool.available] [4, 5] Since MARKER 5 is still the last one added to the stack, it will be the first popped: >>> c1 = db.open(); c2 = db.open() >>> c1.MARKER, c2.MARKER (5, 4) >>> len(pool.available), len(pool.all) (0, 2) Next: when a closed Connection is removed from .available due to exceeding pool_size, that Connection's cache is cleared (this behavior was new in ZODB 3.6b6). While user code may still hold a reference to that Connection, once it vanishes from .available it's really not usable for anything sensible (it can never be in the open state again). Waiting for gc to reclaim the Connection and its cache eventually works, but that can take "a long time" and caches can hold on to many objects, and limited resources (like RDB connections), for the duration. >>> st.close() >>> st = Storage() >>> db = DB(st, pool_size=2) >>> conn0 = db.open() >>> len(conn0._cache) # empty now 0 >>> import transaction >>> conn0.root()['a'] = 1 >>> transaction.commit() >>> len(conn0._cache) # but now the cache holds the root object 1 Now open more connections so that the total exceeds pool_size (2): >>> conn1 = db.open(); _ = conn1.root()['a'] >>> conn2 = db.open(); _ = conn2.root()['a'] Note that we accessed the objects in the new connections so they would be of the same size, so that when they get closed, they don't sink below conn0. >>> pool = db.pool >>> len(pool.all), len(pool.available) # all Connections are in use (3, 0) Return pool_size (2) Connections to the pool: >>> conn0.close() >>> conn1.close() >>> len(pool.all), len(pool.available) (3, 2) >>> len(conn0._cache) # nothing relevant has changed yet 1 When we close the third connection, conn0 will be booted from .all, and we expect its cache to be cleared then: >>> conn2.close() >>> len(pool.all), len(pool.available) (2, 2) >>> len(conn0._cache) # conn0's cache is empty again 0 >>> del conn0, conn1, conn2 Clean up. >>> st.close() >>> handler.uninstall() zope2.13-2.13.21/source/ZODB3/src/ZODB/tests/Corruption.py0000644000175000017500000000437012214017464021472 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

The tested behavior is new in ZODB 3.4. First define a lightweight storage with a ``sync()`` method: >>> import ZODB >>> from ZODB.MappingStorage import MappingStorage >>> import transaction >>> class SimpleStorage(MappingStorage): ... sync_called = False ... ... def sync(self, *args): ... self.sync_called = True Make a change locally: >>> st = SimpleStorage() >>> db = ZODB.DB(st) >>> cn = db.open() >>> rt = cn.root() >>> rt['a'] = 1 Sync should not have been called yet. >>> st.sync_called # False before 3.4 False ``sync()`` is called by the Connection's ``afterCompletion()`` hook after the commit completes. >>> transaction.commit() >>> st.sync_called # False before 3.4 True ``sync()`` is also called by the ``afterCompletion()`` hook after an abort. >>> st.sync_called = False >>> rt['b'] = 2 >>> transaction.abort() >>> st.sync_called # False before 3.4 True And ``sync()`` is called whenever we explicitly start a new transaction, via the ``newTransaction()`` hook. >>> st.sync_called = False >>> dummy = transaction.begin() >>> st.sync_called # False before 3.4 True Clean up. Closing db isn't enough -- closing a DB doesn't close its `Connections`. Leaving our `Connection` open here can cause the ``SimpleStorage.sync()`` method to get called later, during another test, and our doctest-synthesized module globals no longer exist then. You get a weird traceback then ;-) >>> cn.close() One more, very obscure. It was the case that if the first action a new threaded transaction manager saw was a ``begin()`` call, then synchronizers registered after that in the same transaction weren't communicated to the `Transaction` object, and so the synchronizers' ``afterCompletion()`` hooks weren't called when the transaction commited. None of the test suites (ZODB's, Zope 2.8's, or Zope3's) caught that, but apparently Zope 3 takes this path at some point when serving pages. >>> tm = transaction.ThreadTransactionManager() >>> st.sync_called = False >>> dummy = tm.begin() # we're doing this _before_ opening a connection >>> cn = db.open(transaction_manager=tm) >>> rt = cn.root() # make a change >>> rt['c'] = 3 >>> st.sync_called False Now ensure that ``cn.afterCompletion() -> st.sync()`` gets called by commit despite that the `Connection` registered after the transaction began: >>> tm.commit() >>> st.sync_called True And try the same thing with a non-threaded transaction manager: >>> cn.close() >>> tm = transaction.TransactionManager() >>> st.sync_called = False >>> dummy = tm.begin() # we're doing this _before_ opening a connection >>> cn = db.open(transaction_manager=tm) >>> rt = cn.root() # make a change >>> rt['d'] = 4 >>> st.sync_called False >>> tm.commit() >>> st.sync_called True >>> cn.close() >>> db.close() zope2.13-2.13.21/source/ZODB3/src/ZODB/tests/warnhook.py0000644000175000017500000000410212214017464021147 0ustar arnauarnau############################################################################## # # Copyright (c) 2004 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

NON-UNDOING =========== We need an database with a NON-undoing blob supporting storage: >>> base_storage = MappingStorage('storage') >>> blob_storage = BlobStorage(blob_dir, base_storage) >>> database = DB(blob_storage) Create our root object: >>> connection1 = database.open() >>> root = connection1.root() Put some revisions of a blob object in our database and on the filesystem: >>> import time, os >>> tids = [] >>> times = [] >>> nothing = transaction.begin() >>> times.append(new_time()) >>> blob = Blob() >>> blob.open('w').write('this is blob data 0') >>> root['blob'] = blob >>> transaction.commit() >>> tids.append(blob_storage._tid) >>> nothing = transaction.begin() >>> times.append(new_time()) >>> root['blob'].open('w').write('this is blob data 1') >>> transaction.commit() >>> tids.append(blob_storage._tid) >>> nothing = transaction.begin() >>> times.append(new_time()) >>> root['blob'].open('w').write('this is blob data 2') >>> transaction.commit() >>> tids.append(blob_storage._tid) >>> nothing = transaction.begin() >>> times.append(new_time()) >>> root['blob'].open('w').write('this is blob data 3') >>> transaction.commit() >>> tids.append(blob_storage._tid) >>> nothing = transaction.begin() >>> times.append(new_time()) >>> root['blob'].open('w').write('this is blob data 4') >>> transaction.commit() >>> tids.append(blob_storage._tid) >>> oid = root['blob']._p_oid >>> fns = [ blob_storage.fshelper.getBlobFilename(oid, x) for x in tids ] >>> [ os.path.exists(x) for x in fns ] [True, True, True, True, True] Get our blob filenames for this oid. >>> fns = [ blob_storage.fshelper.getBlobFilename(oid, x) for x in tids ] Do a pack to the slightly before the first revision was written: >>> packtime = times[0] >>> blob_storage.pack(packtime, referencesf) >>> [ os.path.exists(x) for x in fns ] [False, False, False, False, True] Do a pack to now: >>> packtime = new_time() >>> blob_storage.pack(packtime, referencesf) >>> [ os.path.exists(x) for x in fns ] [False, False, False, False, True] Delete the object and do a pack, it should get rid of the most current revision as well as the entire directory: >>> nothing = transaction.begin() >>> del root['blob'] >>> transaction.commit() >>> packtime = new_time() >>> blob_storage.pack(packtime, referencesf) >>> [ os.path.exists(x) for x in fns ] [False, False, False, False, False] >>> os.path.exists(os.path.split(fns[0])[0]) False Avoiding parallel packs ======================= Blob packing (similar to FileStorage) can only be run once at a time. For this, a flag (_blobs_pack_is_in_progress) is set.

ZODB serializes objects using a custom format based on Python pickles. When an object is unserialized, it can be loaded as either a ghost or a real object. A ghost is a persistent object of the appropriate type but without any state. The first time a ghost is accessed, the persistence machinery traps access and loads the actual state. A ghost allows many persistent objects to be loaded while minimizing the memory consumption of referenced but otherwise unused objects. Pickle format ------------- ZODB stores serialized objects using a custom format based on pickle. Each serialized object has two parts: the class description and the object state. The class description must provide enough information to call the class's ``__new__`` and create an empty object. Once the object exists as a ghost, its state is passed to ``__setstate__``. The class description can be in a variety of formats, in part to provide backwards compatibility with earlier versions of Zope. The four current formats for class description are: 1. type(obj) 2. type(obj), obj.__getnewargs__() 3. (module name, class name), None 7. (module name, class name), obj.__getnewargs__() The second of these options is used if the object has a __getnewargs__() method. It is intended to support objects like persistent classes that have custom C layouts that are determined by arguments to __new__(). The third and fourth (#3 & #7) apply to instances of a persistent class (which means the class itself is persistent, not that it's a subclass of Persistent). The type object is usually stored using the standard pickle mechanism, which involves the pickle GLOBAL opcode (giving the type's module and name as strings). The type may itself be a persistent object, in which case a persistent reference (see below) is used. It's unclear what "usually" means in the last paragraph. There are two useful places to concentrate confusion about exactly which formats exist: - ObjectReader.getClassName() below returns a dotted "module.class" string, via actually loading a pickle. This requires that the implementation of application objects be available. - ZODB/utils.py's get_pickle_metadata() tries to return the module and class names (as strings) without importing any application modules or classes, via analyzing the pickle. Earlier versions of Zope supported several other kinds of class descriptions. The current serialization code reads these descriptions, but does not write them. The three earlier formats are: 4. (module name, class name), __getinitargs__() 5. class, None 6. class, __getinitargs__() Formats 4 and 6 are used only if the class defines a __getinitargs__() method, but we really can't tell them apart from formats 7 and 2 (respectively). Formats 5 and 6 are used if the class does not have a __module__ attribute (I'm not sure when this applies, but I think it occurs for some but not all ZClasses). Persistent references --------------------- When one persistent object pickle refers to another persistent object, the database uses a persistent reference. ZODB persistent references are of the form:: oid A simple object reference. (oid, class meta data) A persistent object reference [reference_type, args] An extended reference Extension references come in a number of subforms, based on the reference types. The following reference types are defined: 'w' Persistent weak reference. The arguments consist of an oid and optionally a database name. The following are planned for the future: 'n' Multi-database simple object reference. The arguments consist of a database name, and an object id. 'm' Multi-database persistent object reference. The arguments consist of a database name, an object id, and class meta data. The following legacy format is also supported. [oid] A persistent weak reference Because the persistent object reference forms include class information, it is not possible to change the class of a persistent object for which this form is used. If a transaction changed the class of an object, a new record with new class metadata would be written but all the old references would still use the old class. (It is possible that we could deal with this limitation in the future.) An object id is used alone when a class requires arguments to it's __new__ method, which is signalled by the class having a __getnewargs__ attribute. A number of legacyforms are defined: """ import cPickle import cStringIO import logging from persistent import Persistent from persistent.wref import WeakRefMarker, WeakRef from ZODB import broken from ZODB.broken import Broken from ZODB.POSException import InvalidObjectReference _oidtypes = str, type(None) # Might to update or redo coptimizations to reflect weakrefs: # from ZODB.coptimizations import new_persistent_id def myhasattr(obj, name, _marker=object()): """Make sure we don't mask exceptions like hasattr().

I don't know how this would happen in the wild. In 3.10.3, the ZEO tpc_abort call to the server is changed to be synchronous, which should address this case. Maybe there's another case. Performance enhancements ------------------------ - Improved ZEO client cache implementation to make it less likely to evict objects that are being used. - Small (possibly negligable) reduction in CPU in ZEO storage servers to service object loads and in networking code. 3.10.2 (2011-02-12) =================== Bugs Fixed ---------- - 3.10 introduced an optimization to try to address BTree conflict errors arrising for basing BTree keys on object ids. The optimization caused object ids allocated in aborted transactions to be reused. Unfortunately, this optimzation led to some rather severe failures in some applications. The symptom is a conflict error in which one of the serials mentioned is zero. This optimization has been removed. See (for example): https://bugs.launchpad.net/zodb/+bug/665452 - ZEO server transaction timeouts weren't logged as critical. https://bugs.launchpad.net/zodb/+bug/670986 3.10.1 (2010-10-27) =================== Bugs Fixed ---------- - When a transaction rolled back a savepoint after adding objects and subsequently added more objects and committed, an error could be raised "ValueError: A different object already has the same oid" causing the transaction to fail. Worse, this could leave a database in a state where subsequent transactions in the same process would fail. https://bugs.launchpad.net/zodb/+bug/665452 - Unix domain sockets didn't work for ZEO (since the addition of IPv6 support). https://bugs.launchpad.net/zodb/+bug/663259 - Removed a missfeature that can cause performance problems when using an external garbage collector with ZEO. When objects were deleted from a storage, invalidations were sent to clients. This makes no sense. It's wildly unlikely that the other connections/clients have copies of the garbage. In normal storage garbage collection, we don't send invalidations. There's no reason to send them when an external garbage collector is used. - ZEO client cache simulation misshandled invalidations causing incorrect statistics and errors. 3.10.0 (2010-10-08) =================== New Features ------------ - There are a number of performance enhancements for ZEO storage servers. - FileStorage indexes use a new format. They are saved and loaded much faster and take less space. Old indexes can still be read, but new indexes won't be readable by older versions of ZODB. - The API for undoing multiple transactions has changed. To undo multiple transactions in a single transaction, pass a list of transaction identifiers to a database's undoMultiple method. Calling a database's undo method multiple times in the same transaction now raises an exception. - The ZEO protocol for undo has changed. The only user-visible consequence of this is that when ZODB 3.10 ZEO servers won't support undo for older clients. - The storage API (IStorage) has been tightened. Now, storages should raise a StorageTransactionError when invalid transactions are passed to tpc_begin, tpc_vote, or tpc_finish. - ZEO clients (``ClientStorage`` instances) now work in forked processes, including those created via ``multiprocessing.Process`` instances. - Broken objects now provide the IBroken interface. - As a convenience, you can now pass an integer port as an address to the ZEO ClientStorage constructor. - As a convenience, there's a new ``client`` function in the ZEO package for constructing a ClientStorage instance. It takes the same arguments as the ClientStorage constructor. - DemoStorages now accept constructor athuments, close_base_on_close and close_changes_on_close, to control whether underlying storages are closed when the DemoStorage is closed. https://bugs.launchpad.net/zodb/+bug/118512 - Removed the dependency on zope.proxy. - Removed support for the _p_independent mini framework, which was made moot by the introduction of multi-version concurrency control several years ago. - Added support for the transaction retry convenience (transaction-manager attempts method) introduced in the ``transaction`` 1.1.0 release. - Enhanced the database opening conveniences: - You can now pass storage keyword arguments to ZODB.DB and ZODB.connection. - You can now pass None (rather than a storage or file name) to get a database with a mapping storage. - Databases now warn when committing very large records (> 16MB). This is to try to warn people of likely design mistakes. There is a new option (large_record_size/large-record-size) to control the record size at which the warning is issued. - Added support for wrapper storages that transform pickle data. Applications for this include compression and encryption. An example wrapper storage implementation, ZODB.tests.hexstorage, was included for testing. It is important that storage implementations not assume that storages contain pickles. Renamed IStorageDB to IStorageWrapper and expanded it to provide methods for transforming and untransforming data records. Storages implementations should use these methods to get pickle data from stored records. - Deprecated ZODB.interfaces.StorageStopIteration. Storage iterator implementations should just raise StopIteration, which means they can now be implemented as generators. - The filestorage packer configuration option noe accepts values of the form ``modname:expression``, allowing the use of packer factories with options. - Added a new API that allows applications to make sure that current data are read. For example, with:: self._p_jar.readCurrent(ob) A conflict error will be raised if the version of ob read by the transaction isn't current when the transaction is committed. Normally, ZODB only assures that objects read are consistent, but not necessarily up to date. Checking whether an object is up to date is important when information read from one object is used to update another. BTrees are an important case of reading one object to update another. Internal nodes are read to decide which leave notes are updated when a BTree is updated. BTrees now use this new API to make sure that internal nodes are up to date on updates. - When transactions are aborted, new object ids allocated during the transaction are saved and used in subsequent transactions. This can help in situations where object ids are used as BTree keys and the sequential allocation of object ids leads to conflict errors. - ZEO servers now support a server_status method for for getting information on the number of clients, lock requests and general statistics. - ZEO clients now support a client_label constructor argument and client-label configuration-file option to specify a label for a client in server logs. This makes it easier to identify specific clients corresponding to server log entries, especially when there are multiple clients originating from the same machine. - Improved ZEO server commit lock logging. Now, locking activity is logged at the debug level until the number of waiting lock requests gets above 3. Log at the critical level when the number of waiting lock requests gets above 9. - The file-storage backup script, repozo, will now create a backup index file if an output file name is given via the --output/-o option. - Added a '--kill-old-on-full' argument to the repozo backup options: if passed, remove any older full or incremental backup files from the repository after doing a full backup. (https://bugs.launchpad.net/zope2/+bug/143158) - The mkzeoinst script has been moved to a separate project: http://pypi.python.org/pypi/zope.mkzeoinstance and is no-longer included with ZODB. - Removed untested unsupported dbmstorage fossile. - ZEO servers no longer log their pids in every log message. It's just not interesting. :) Bugs fixed ---------- - When a pool timeout was specified for a database and old connections were removed due to timing out, an error occured due to a bug in the connection cleanup logic. - When multi-database connections were no longer used and cleaned up, their subconnections weren't cleaned up properly. - ZEO didn't work with IPv6 addrsses. Added IPv6 support contributed by Martin v. Löwis. - A file storage bug could cause ZEO clients to have incorrect information about current object revisions after reconnecting to a database server. - Updated the 'repozo --kill-old-on-full' option to remove any '.index' files corresponding to backups being removed. - ZEO extension methods failed when a client reconnected to a storage. (https://bugs.launchpad.net/zodb/+bug/143344) - Clarified the return Value for lastTransaction in the case when there aren't any transactions. Now a string of 8 nulls (aka "z64") is specified. - Setting _p_changed on a blob wo actually writing anything caused an error. (https://bugs.launchpad.net/zodb/+bug/440234) - The verbose mode of the fstest was broken. (https://bugs.launchpad.net/zodb/+bug/475996) - Object ids created in a savepoint that is rolled back wren't being reused. (https://bugs.launchpad.net/zodb/+bug/588389) - Database connections didn't invalidate cache entries when conflict errors were raised in response to checkCurrentSerialInTransaction errors. Normally, this shouldn't be a problem, since there should be pending invalidations for these oids which will cause the object to be invalidated. There have been issues with ZEO persistent cache management that have caused out of date data to remain in the cache. (It's possible that the last of these were addressed in the 3.10.0b5.) Invalidating read data when there is a conflict error provides some extra insurance. - The interface, ZODB.interfaces.IStorage was incorrect. The store method should never return a sequence of oid and serial pairs. - When a demo storage push method was used to create a new demo storage and the new storage was closed, the original was (incorrectly) closed. - There were numerous bugs in the ZEO cache tracing and analysis code. Cache simulation, while not perfect, seems to be much more accurate now than it was before. The ZEO cache trace statistics and simulation scripts have been given more descriptive names and moved to the ZEO scripts package. - BTree sets and tree sets didn't correctly check values passed to update or to constructors, causing Python to exit under certain circumstances. - Fixed bug in copying a BTrees.Length instance. (https://bugs.launchpad.net/zodb/+bug/516653) - Fixed a serious bug that caused cache failures when run with Python optimization turned on. https://bugs.launchpad.net/zodb/+bug/544305 - When using using a ClientStorage in a Storage server, there was a threading bug that caused clients to get disconnected. - On Mac OS X, clients that connected and disconnected quickly could cause a ZEO server to stop accepting connections, due to a failure to catch errors in the initial part of the connection process. The failure to properly handle exceptions while accepting connections is potentially problematic on other platforms. Fixes: https://bugs.launchpad.net/zodb/+bug/135108 - Object state management wasn't done correctly when classes implemented custom _p_deavtivate methods.

(Of course, it is only usable on POSIX-complient systems. Using zdaemon requires specifying a number of options, which can be given in a configuration file, or as command-line options. It also accepts commands teling it what do do. The commands are: start Start a process as a daemon stop Stop a running daemon process restart Stop and then restart a program status Find out if the program is running foreground or fg Run a program kill signal Send a signal to the daemon process reopen_transcript Reopen the transcript log. See the discussion of the transcript log below. help command Get help on a command Commands can be given on a command line, or can be given using an interactive interpreter. Let's start with a simple example. We'll use command-line options to run the echo command: >>> system("./zdaemon -p 'echo hello world' fg") echo hello world hello world Here we used the -p option to specify a program to run. We can specify a program name and command-line options in the program command. Note, however, that the command-line parsing is pretty primitive. Quotes and spaces aren't handled correctly. Let's look at a slightly more complex example. We'll run the sleep command as a daemon :) >>> system("./zdaemon -p 'sleep 100' start") . . daemon process started, pid=819 This ran the sleep deamon. We can check whether it ran with the status command: >>> system("./zdaemon -p 'sleep 100' status") program running; pid=819 We can stop it with the stop command: >>> system("./zdaemon -p 'sleep 100' stop") . . daemon process stopped >>> system("./zdaemon -p 'sleep 100' status") daemon manager not running Normally, we control zdaemon using a configuration file. Let's create a typical configuration file: >>> open('conf', 'w').write( ... ''' ... ... program sleep 100 ... ... ''') Now, we can run with the -C option to read the configuration file: >>> system("./zdaemon -Cconf start") . . daemon process started, pid=1136 If we list the directory: >>> system("ls") conf zdaemon zdsock We'll see that a file, zdsock, was created. This is a unix-domain socket used internally by ZDaemon. We'll normally want to control where this goes. >>> system("./zdaemon -Cconf stop") . . daemon process stopped >>> open('conf', 'w').write( ... ''' ... ... program sleep 100 ... socket-name /tmp/demo.zdsock ... ... '''.replace('/tmp', tmpdir)) >>> system("./zdaemon -Cconf start") . . daemon process started, pid=1139 >>> system("ls") conf zdaemon >>> import os >>> os.path.exists("/tmp/demo.zdsock".replace('/tmp', tmpdir)) True >>> system("./zdaemon -Cconf stop") . . daemon process stopped In the example, we included a command-line argument in the program option. We can also provide options on the command line: >>> open('conf', 'w').write( ... ''' ... ... program sleep ... socket-name /tmp/demo.zdsock ... ... '''.replace('/tmp', tmpdir)) >>> system("./zdaemon -Cconf start 100") . . daemon process started, pid=1149 >>> system("./zdaemon -Cconf status") program running; pid=1149 >>> system("./zdaemon -Cconf stop") . . daemon process stopped Environment Variables ===================== Sometimes, it is necessary to set environment variables before running a program. Perhaps the most common case for this is setting LD_LIBRARY_PATH so that dynamically loaded libraries can be found. >>> open('conf', 'w').write( ... ''' ... ... program env ... socket-name /tmp/demo.zdsock ... ... ... LD_LIBRARY_PATH /home/foo/lib ... HOME /home/foo ... ... '''.replace('/tmp', tmpdir)) >>> system("./zdaemon -Cconf fg") env USER=jim HOME=/home/foo LOGNAME=jim USERNAME=jim TERM=dumb PATH=/home/jim/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin EMACS=t LANG=en_US.UTF-8 SHELL=/bin/bash EDITOR=emacs LD_LIBRARY_PATH=/home/foo/lib Transcript log ============== When zdaemon run a program in daemon mode, it disconnects the program's standard input, standard output, and standard error from the controlling terminal. It can optionally redirect the output to standard error and standard output to a file. This is done with the transcript option. This is, of course, useful for logging output from long-running applications. Let's look at an example. We'll have a long-running process that simple tails a data file: >>> f = open('data', 'w', 0) >>> import os >>> f.write('rec 1\n'); os.fsync(f.fileno()) >>> open('conf', 'w').write( ... ''' ... ... program tail -f data ... transcript log ... ... ''') >>> system("./zdaemon -Cconf start") . . daemon process started, pid=7963 .. Wait a little bit to make sure tail has a chance to work >>> import time >>> time.sleep(0.1) Now, if we look at the log file, it contains the tail output: >>> open('log').read() 'rec 1\n' We can rotate the transcript log by renaming it and telling zdaemon to reopen it: >>> import os >>> os.rename('log', 'log.1') If we generate more output: >>> f.write('rec 2\n'); os.fsync(f.fileno()) .. Wait a little bit to make sure tail has a chance to work >>> time.sleep(1) The output will appear in the old file, because zdaemon still has it open: >>> open('log.1').read() 'rec 1\nrec 2\n' Now, if we tell zdaemon to reopen the file: >>> system("./zdaemon -Cconf reopen_transcript") and generate some output: >>> f.write('rec 3\n'); os.fsync(f.fileno()) .. Wait a little bit to make sure tail has a chance to work >>> time.sleep(1) the output will show up in the new file, not the old: >>> open('log').read() 'rec 3\n' >>> open('log.1').read() 'rec 1\nrec 2\n' Reference Documentation ======================= The following options are available for use in the runner section of configuration files and as command-line options. program Command-line option: -p or --program This option gives the command used to start the subprocess managed by zdaemon. This is currently a simple list of whitespace-delimited words. The first word is the program file, subsequent words are its command line arguments. If the program file contains no slashes, it is searched using $PATH. (Note that there is no way to to include whitespace in the program file or an argument, and under certain circumstances other shell metacharacters are also a problem.) socket-name Command-line option: -s or --socket-name. The pathname of the Unix domain socket used for communication between the zdaemon command-line tool and a deamon-management process. The default is relative to the current directory in which zdaemon is started. You want to specify an absolute pathname here. This defaults to "zdsock", which is created in the directory in which zdrun is started. daemon Command-line option: -d or --daemon. If this option is true, zdaemon runs in the background as a true daemon. It forks a child process which becomes the subprocess manager, while the parent exits (making the shell that started it believe it is done). The child process also does the following: - if the directory option is set, change into that directory - redirect stdin, stdout and stderr to /dev/null - call setsid() so it becomes a session leader - call umask() with specified value The default for this option is on by default. The command-line option therefore has no effect. To disable daemon mode, you must use a configuration file:: program sleep 1 daemon off directory Command-line option: -z or --directory. If the daemon option is true (default), this option can specify a directory into which zdrun.py changes as part of the "daemonizing". If the daemon option is false, this option is ignored. backoff-limit Command-line option: -b or --backoff-limit. When the subprocess crashes, zdaemon inserts a one-second delay before it restarts it. When the subprocess crashes again right away, the delay is incremented by one second, and so on. What happens when the delay has reached the value of backoff-limit (in seconds), depends on the value of the forever option. If forever is false, zdaemon gives up at this point, and exits. An always-crashing subprocess will have been restarted exactly backoff-limit times in this case. If forever is true, zdaemon continues to attempt to restart the process, keeping the delay at backoff-limit seconds. If the subprocess stays up for more than backoff-limit seconds, the delay is reset to 1 second. This defaults to 10. forever Command-line option: -f or --forever. If this option is true, zdaemon will keep restarting a crashing subprocess forever. If it is false, it will give up after backoff-limit crashes in a row. See the description of backoff-limit for details. This is disabled by default. exit-codes Command-line option: -x or --exit-codes. This defaults to 0,2. If the subprocess exits with an exit status that is equal to one of the integers in this list, zdaemon will not restart it. The default list requires some explanation. Exit status 0 is considered a willful successful exit; the ZEO and Zope server processes use this exit status when they want to stop without being restarted. (Including in response to a SIGTERM.) Exit status 2 is typically issued for command line syntax errors; in this case, restarting the program will not help! NOTE: this mechanism overrides the backoff-limit and forever options; i.e. even if forever is true, a subprocess exit status code in this list makes zdaemon give up. To disable this, change the value to an empty list. user Command-line option: -u or --user. When zdaemon is started by root, this option specifies the user as who the the zdaemon process (and hence the daemon subprocess) will run. This can be a user name or a numeric user id. Both the user and the group are set from the corresponding password entry, using setuid() and setgid(). This is done before zdaemon does anything else besides parsing its command line arguments. NOTE: when zdaemon is not started by root, specifying this option is an error. (XXX This may be a mistake.) XXX The zdaemon event log file may be opened *before* setuid() is called. Is this good or bad? umask Command-line option: -m or --umask. When daemon mode is used, this option specifies the octal umask of the subprocess. default-to-interactive If this option is true, zdaemon enters interactive mode when it is invoked without a positional command argument. If it is false, you must use the -i or --interactive command line option to zdaemon to enter interactive mode. This is enabled by default. logfile This option specifies a log file that is the default target of the "logtail" zdaemon command. NOTE: This is NOT the log file to which zdaemon writes its logging messages! That log file is specified by the section described below. transcript The name of a file in which a transcript of all output from the command being run will be written to when daemonized. If not specified, output from the command will be discarded. This only takes effect when the "daemon" option is enabled. prompt The prompt shown by the controller program. The default must be provided by the application. (Note that a few other options are available to support old configuration files, but aren't needed any more and can generally be ignored.) In addition to the runner section, you can use an eventlog section that specified one or more logfile subsections:: path /var/log/foo/foo.log path STDOUT In this example, log output is sent to a file and to standard out. Log output from zdaemon usually isn't very interesting but can be handy for debugging. =========== Changelog =========== 2.0.7 (2012-06-08) ================== - Fixed: The change in 2.0.6 to set a user's supplemental groups broke common configurations in which the effective user was set via ``su`` or ``sudo -u`` prior to invoking zdaemon. Now, zdaemon doesn't set groups or the effective user if the effective user is already set to the configured user. 2.0.6 (2012-06-07) ================== - Fixed: When the ``user`` option was used to run as a particular user, supplemental groups weren't set to the user's supplemental groups. 2.0.5 (2012-06-07) ================== (Accidental release. Please ignore.) 2.0.4 (2009-04-20) ================== - Version 2.0.3 broke support for relative paths to the socket (``-s`` option and ``socket-name`` parameter), now relative paths work again as in version 2.0.2. - Fixed change log format, made table of contents nicer. - Fixed author's email address. - Removed zpkg stuff. 2.0.3 (2009-04-11) ================== - Added support to bootstrap on Jython. - If the run directory does not exist it will be created. This allow to use `/var/run/mydaemon` as run directory when /var/run is a tmpfs (LP #318118). Bugs Fixed ---------- - No longer uses a hardcoded filename (/tmp/demo.zdsock) in unit tests. This lets you run the tests on Python 2.4 and 2.5 simultaneously without spurious errors. - make -h work again for both runner and control scripts. Help is now taken from the __doc__ of the options class users by the zdaemon script being run. 2.0.2 (2008-04-05) ================== Bugs Fixed ---------- - Fixed backwards incompatible change in handling of environment option. 2.0.1 (2007-10-31) ================== Bugs Fixed ---------- - Fixed test renormalizer that did not work in certain cases where the environment was complex. 2.0.0 (2007-07-19) ================== - Final release for 2.0.0. 2.0a6 (2007-01-11) ================== Bugs Fixed ---------- - When the user option was used, it only affected running the daemon. 2.0a3, 2.0a4, 2.0a5 (2007-01-10) ================================ Bugs Fixed ---------- - The new (2.0) mechanism used by zdaemon to start the daemon manager broke some applications that extended zdaemon. - Added extra checks to deal with programs that extend zdaemon and copy the schema and thus don't see updates to the ZConfig schema. 2.0a2 (2007-01-10) ================== New Features ------------ - Added support for setting environment variables in the configuration file. This is useful when zdaemon is used to run programs that need environment variables set (e.g. LD_LIBRARY_PATH). - Added a command to rotate the transcript log. 2.0a1 (2006-12-21) ================== Bugs Fixed ---------- - In non-daemon mode, start hung, producing annoying dots when the program exited. - The start command hung producing annoying dots if the deamon failed to start. - foreground and start had different semantics because one used os.system and another used os.spawn New Features ------------ - Documentation - Command-line arguments can now be supplied to the start and foreground (fg) commands - zdctl now invokes itself to run zdrun. This means that it's no-longer necessary to generate a separate zdrun script. This especially when the magic techniques to find and run zdrun using directory sniffing fail to set the path corrrectly. - The daemon mode is now enabled by default. To get non-deamon mode, you have to use a configuration file and set deamon to off there. The old -d option is kept for backward compatibility, but is a no-op. 1.4a1 (2005-11-21) ================== - Fixed a bug in the distribution setup file. 1.4a1 (2005-11-05) ================== - First semi-formal release. After some unknown release(???) =============================== - Made 'zdaemon.zdoptions' not fail for --help when __main__.__doc__ is None. After 1.1 ========= - Updated test 'testRunIgnoresParentSignals': o Use 'mkdtemp' to create a temporary directory to hold the test socket rather than creating the test socket in the test directory. Hopefully this will be more robust. Sometimes the test directory has a path so long that the test socket can't be created. o Changed management of 'donothing.sh'. This script is now created by the test in the temporarary directory with the necessary permissions. This is to avoids possible mangling of permissions leading to spurious test failures. It also avoids management of a file in the source tree, which is a bonus. - Rearranged source tree to conform to more usual zpkg-based layout: o Python package lives under 'src'. o Dependencies added to 'src' as 'svn:externals'. o Unit tests can now be run from a checkout. - Made umask-based test failures due to running as root emit a more forceful warning. 1.1 (2005-06-09) ================ - SVN tag: svn://svn.zope.org/repos/main/zdaemon/tags/zdaemon-1.1 - Tagged to make better 'svn:externals' linkage possible.

Wait a little bit to make sure tail has a chance to work >>> time.sleep(1) the output will show up in the new file, not the old: >>> open('log').read() 'rec 3\n' >>> open('log.1').read() 'rec 1\nrec 2\n' Reference Documentation ======================= The following options are available for use in the runner section of configuration files and as command-line options. program Command-line option: -p or --program This option gives the command used to start the subprocess managed by zdaemon. This is currently a simple list of whitespace-delimited words. The first word is the program file, subsequent words are its command line arguments. If the program file contains no slashes, it is searched using $PATH. (Note that there is no way to to include whitespace in the program file or an argument, and under certain circumstances other shell metacharacters are also a problem.) socket-name Command-line option: -s or --socket-name. The pathname of the Unix domain socket used for communication between the zdaemon command-line tool and a deamon-management process. The default is relative to the current directory in which zdaemon is started. You want to specify an absolute pathname here. This defaults to "zdsock", which is created in the directory in which zdrun is started. daemon Command-line option: -d or --daemon. If this option is true, zdaemon runs in the background as a true daemon. It forks a child process which becomes the subprocess manager, while the parent exits (making the shell that started it believe it is done). The child process also does the following: - if the directory option is set, change into that directory - redirect stdin, stdout and stderr to /dev/null - call setsid() so it becomes a session leader - call umask() with specified value The default for this option is on by default. The command-line option therefore has no effect. To disable daemon mode, you must use a configuration file:: program sleep 1 daemon off directory Command-line option: -z or --directory. If the daemon option is true (default), this option can specify a directory into which zdrun.py changes as part of the "daemonizing". If the daemon option is false, this option is ignored. backoff-limit Command-line option: -b or --backoff-limit. When the subprocess crashes, zdaemon inserts a one-second delay before it restarts it. When the subprocess crashes again right away, the delay is incremented by one second, and so on. What happens when the delay has reached the value of backoff-limit (in seconds), depends on the value of the forever option. If forever is false, zdaemon gives up at this point, and exits. An always-crashing subprocess will have been restarted exactly backoff-limit times in this case. If forever is true, zdaemon continues to attempt to restart the process, keeping the delay at backoff-limit seconds. If the subprocess stays up for more than backoff-limit seconds, the delay is reset to 1 second. This defaults to 10. forever Command-line option: -f or --forever. If this option is true, zdaemon will keep restarting a crashing subprocess forever. If it is false, it will give up after backoff-limit crashes in a row. See the description of backoff-limit for details. This is disabled by default. exit-codes Command-line option: -x or --exit-codes. This defaults to 0,2. If the subprocess exits with an exit status that is equal to one of the integers in this list, zdaemon will not restart it. The default list requires some explanation. Exit status 0 is considered a willful successful exit; the ZEO and Zope server processes use this exit status when they want to stop without being restarted. (Including in response to a SIGTERM.) Exit status 2 is typically issued for command line syntax errors; in this case, restarting the program will not help! NOTE: this mechanism overrides the backoff-limit and forever options; i.e. even if forever is true, a subprocess exit status code in this list makes zdaemon give up. To disable this, change the value to an empty list. user Command-line option: -u or --user. When zdaemon is started by root, this option specifies the user as who the the zdaemon process (and hence the daemon subprocess) will run. This can be a user name or a numeric user id. Both the user and the group are set from the corresponding password entry, using setuid() and setgid(). This is done before zdaemon does anything else besides parsing its command line arguments. NOTE: when zdaemon is not started by root, specifying this option is an error. (XXX This may be a mistake.) XXX The zdaemon event log file may be opened *before* setuid() is called. Is this good or bad? umask Command-line option: -m or --umask. When daemon mode is used, this option specifies the octal umask of the subprocess. default-to-interactive If this option is true, zdaemon enters interactive mode when it is invoked without a positional command argument. If it is false, you must use the -i or --interactive command line option to zdaemon to enter interactive mode. This is enabled by default. logfile This option specifies a log file that is the default target of the "logtail" zdaemon command. NOTE: This is NOT the log file to which zdaemon writes its logging messages! That log file is specified by the section described below. transcript The name of a file in which a transcript of all output from the command being run will be written to when daemonized. If not specified, output from the command will be discarded. This only takes effect when the "daemon" option is enabled. prompt The prompt shown by the controller program. The default must be provided by the application. (Note that a few other options are available to support old configuration files, but aren't needed any more and can generally be ignored.) In addition to the runner section, you can use an eventlog section that specified one or more logfile subsections:: path /var/log/foo/foo.log path STDOUT In this example, log output is sent to a file and to standard out. Log output from zdaemon usually isn't very interesting but can be handy for debugging. =========== Changelog =========== 2.0.7 (2012-06-08) ================== - Fixed: The change in 2.0.6 to set a user's supplemental groups broke common configurations in which the effective user was set via ``su`` or ``sudo -u`` prior to invoking zdaemon. Now, zdaemon doesn't set groups or the effective user if the effective user is already set to the configured user. 2.0.6 (2012-06-07) ================== - Fixed: When the ``user`` option was used to run as a particular user, supplemental groups weren't set to the user's supplemental groups. 2.0.5 (2012-06-07) ================== (Accidental release. Please ignore.) 2.0.4 (2009-04-20) ================== - Version 2.0.3 broke support for relative paths to the socket (``-s`` option and ``socket-name`` parameter), now relative paths work again as in version 2.0.2. - Fixed change log format, made table of contents nicer. - Fixed author's email address. - Removed zpkg stuff. 2.0.3 (2009-04-11) ================== - Added support to bootstrap on Jython. - If the run directory does not exist it will be created. This allow to use `/var/run/mydaemon` as run directory when /var/run is a tmpfs (LP #318118). Bugs Fixed ---------- - No longer uses a hardcoded filename (/tmp/demo.zdsock) in unit tests. This lets you run the tests on Python 2.4 and 2.5 simultaneously without spurious errors. - make -h work again for both runner and control scripts. Help is now taken from the __doc__ of the options class users by the zdaemon script being run. 2.0.2 (2008-04-05) ================== Bugs Fixed ---------- - Fixed backwards incompatible change in handling of environment option. 2.0.1 (2007-10-31) ================== Bugs Fixed ---------- - Fixed test renormalizer that did not work in certain cases where the environment was complex. 2.0.0 (2007-07-19) ================== - Final release for 2.0.0. 2.0a6 (2007-01-11) ================== Bugs Fixed ---------- - When the user option was used, it only affected running the daemon. 2.0a3, 2.0a4, 2.0a5 (2007-01-10) ================================ Bugs Fixed ---------- - The new (2.0) mechanism used by zdaemon to start the daemon manager broke some applications that extended zdaemon. - Added extra checks to deal with programs that extend zdaemon and copy the schema and thus don't see updates to the ZConfig schema. 2.0a2 (2007-01-10) ================== New Features ------------ - Added support for setting environment variables in the configuration file. This is useful when zdaemon is used to run programs that need environment variables set (e.g. LD_LIBRARY_PATH). - Added a command to rotate the transcript log. 2.0a1 (2006-12-21) ================== Bugs Fixed ---------- - In non-daemon mode, start hung, producing annoying dots when the program exited. - The start command hung producing annoying dots if the deamon failed to start. - foreground and start had different semantics because one used os.system and another used os.spawn New Features ------------ - Documentation - Command-line arguments can now be supplied to the start and foreground (fg) commands - zdctl now invokes itself to run zdrun. This means that it's no-longer necessary to generate a separate zdrun script. This especially when the magic techniques to find and run zdrun using directory sniffing fail to set the path corrrectly. - The daemon mode is now enabled by default. To get non-deamon mode, you have to use a configuration file and set deamon to off there. The old -d option is kept for backward compatibility, but is a no-op. 1.4a1 (2005-11-21) ================== - Fixed a bug in the distribution setup file. 1.4a1 (2005-11-05) ================== - First semi-formal release. After some unknown release(???) =============================== - Made 'zdaemon.zdoptions' not fail for --help when __main__.__doc__ is None. After 1.1 ========= - Updated test 'testRunIgnoresParentSignals': o Use 'mkdtemp' to create a temporary directory to hold the test socket rather than creating the test socket in the test directory. Hopefully this will be more robust. Sometimes the test directory has a path so long that the test socket can't be created. o Changed management of 'donothing.sh'. This script is now created by the test in the temporarary directory with the necessary permissions. This is to avoids possible mangling of permissions leading to spurious test failures. It also avoids management of a file in the source tree, which is a bonus. - Rearranged source tree to conform to more usual zpkg-based layout: o Python package lives under 'src'. o Dependencies added to 'src' as 'svn:externals'. o Unit tests can now be run from a checkout. - Made umask-based test failures due to running as root emit a more forceful warning. 1.1 (2005-06-09) ================ - SVN tag: svn://svn.zope.org/repos/main/zdaemon/tags/zdaemon-1.1 - Tagged to make better 'svn:externals' linkage possible.

The only required option is "program". Many other options have no default value specified in the schema; in some cases, the program calculates a dynamic default, in others, the feature associated with the option is disabled. For those options that also have corresponding command-line options, the command line option (short and long form) are given here too.
Log configuration for zdctl.py and zdrun.py. These applications will normally use the eventlog section at the top level of the configuration, but will use this eventlog section if it exists. (This is done so that the combined schema for the runner and the controlled application will write to the same logs by default, but a separation of logs can be achieved if desired.)
Command-line option: -p or --program (zdctl.py only). This option gives the command used to start the subprocess managed by zdrun.py. This is currently a simple list of whitespace-delimited words. The first word is the program file, subsequent words are its command line arguments. If the program file contains no slashes, it is searched using $PATH. (XXX There is no way to to include whitespace in the program file or an argument, and under certain circumstances other shell metacharacters are also a problem, e.g. the "foreground" command of zdctl.py.) NOTE: zdrun.py doesn't use this option; it uses its positional arguments. Rather, zdctl.py uses this option to determine the positional argument with which to invoke zdrun.py. (XXX This could be better.) Path to the Python interpreter. Used by zdctl.py to start the zdrun.py process. Defaults to sys.executable. Path to the zdrun.py script. Used by zdctl.py to start the zdrun.py process. Defaults to a file named "zdrun.py" in the same directory as zdctl.py. Command-line option: -s or --socket-name. The pathname of the Unix domain socket used for communication between zdctl.py and zdrun.py. The default is relative to the current directory in which zdctl.py and zdrun.py are started. You want to specify an absolute pathname here. Command-line option: -d or --daemon. If this option is true, zdrun.py runs in the background as a true daemon. It forks a child process which becomes the subprocess manager, while the parent exits (making the shell that started it believe it is done). The child process also does the following: - if the directory option is set, change into that directory - redirect stdin, stdout and stderr to /dev/null - call setsid() so it becomes a session leader - call umask() with specified value Command-line option: -z or --directory. If the daemon option is true, this option can specify a directory into which zdrun.py changes as part of the "daemonizing". If the daemon option is false, this option is ignored. Command-line option: -b or --backoff-limit. When the subprocess crashes, zdrun.py inserts a one-second delay before it restarts it. When the subprocess crashes again right away, the delay is incremented by one second, and so on. What happens when the delay has reached the value of backoff-limit (in seconds), depends on the value of the forever option. If forever is false, zdrun.py gives up at this point, and exits. An always-crashing subprocess will have been restarted exactly backoff-limit times in this case. If forever is true, zdrun.py continues to attempt to restart the process, keeping the delay at backoff-limit seconds. If the subprocess stays up for more than backoff-limit seconds, the delay is reset to 1 second. Command-line option: -f or --forever. If this option is true, zdrun.py will keep restarting a crashing subprocess forever. If it is false, it will give up after backoff-limit crashes in a row. See the description of backoff-limit for details. Command-line option: -x or --exit-codes. If the subprocess exits with an exit status that is equal to one of the integers in this list, zdrun.py will not restart it. The default list requires some explanation. Exit status 0 is considered a willful successful exit; the ZEO and Zope server processes use this exit status when they want to stop without being restarted. (Including in response to a SIGTERM.) Exit status 2 is typically issued for command line syntax errors; in this case, restarting the program will not help! NOTE: this mechanism overrides the backoff-limit and forever options; i.e. even if forever is true, a subprocess exit status code in this list makes zdrun.py give up. To disable this, change the value to an empty list. Command-line option: -u or --user. When zdrun.py is started by root, this option specifies the user as who the the zdrun.py process (and hence the daemon subprocess) will run. This can be a user name or a numeric user id. Both the user and the group are set from the corresponding password entry, using setuid() and setgid(). This is done before zdrun.py does anything else besides parsing its command line arguments. NOTE: when zdrun.py is not started by root, specifying this option is an error. (XXX This may be a mistake.) XXX The zdrun.py event log file may be opened *before* setuid() is called. Is this good or bad? Command-line option: -m or --umask. When daemon mode is used, this option specifies the octal umask of the subprocess. If this option is true, the zdrun.py process will remain even when the daemon subprocess is stopped. In this case, zdctl.py will restart zdrun.py as necessary. If this option is false, zdrun.py will exit when the daemon subprocess is stopped (unless zdrun.py intends to restart it). If this option is true, zdctl.py enters interactive mode when it is invoked without a positional command argument. If it is false, you must use the -i or --interactive command line option to zdctl.py to enter interactive mode. This option specifies a log file that is the default target of the "logtail" zdctl.py command. NOTE: This is NOT the log file to which zdrun.py writes its logging messages!

(Of course, it is only usable on POSIX-complient systems. Using zdaemon requires specifying a number of options, which can be given in a configuration file, or as command-line options. It also accepts commands teling it what do do. The commands are: start Start a process as a daemon stop Stop a running daemon process restart Stop and then restart a program status Find out if the program is running foreground or fg Run a program kill signal Send a signal to the daemon process reopen_transcript Reopen the transcript log. See the discussion of the transcript log below. help command Get help on a command Commands can be given on a command line, or can be given using an interactive interpreter. Let's start with a simple example. We'll use command-line options to run the echo command: >>> system("./zdaemon -p 'echo hello world' fg") echo hello world hello world Here we used the -p option to specify a program to run. We can specify a program name and command-line options in the program command. Note, however, that the command-line parsing is pretty primitive. Quotes and spaces aren't handled correctly. Let's look at a slightly more complex example. We'll run the sleep command as a daemon :) >>> system("./zdaemon -p 'sleep 100' start") . . daemon process started, pid=819 This ran the sleep deamon. We can check whether it ran with the status command: >>> system("./zdaemon -p 'sleep 100' status") program running; pid=819 We can stop it with the stop command: >>> system("./zdaemon -p 'sleep 100' stop") . . daemon process stopped >>> system("./zdaemon -p 'sleep 100' status") daemon manager not running Normally, we control zdaemon using a configuration file. Let's create a typical configuration file: >>> open('conf', 'w').write( ... ''' ... ... program sleep 100 ... ... ''') Now, we can run with the -C option to read the configuration file: >>> system("./zdaemon -Cconf start") . . daemon process started, pid=1136 If we list the directory: >>> system("ls") conf zdaemon zdsock We'll see that a file, zdsock, was created. This is a unix-domain socket used internally by ZDaemon. We'll normally want to control where this goes. >>> system("./zdaemon -Cconf stop") . . daemon process stopped >>> open('conf', 'w').write( ... ''' ... ... program sleep 100 ... socket-name /tmp/demo.zdsock ... ... '''.replace('/tmp', tmpdir)) >>> system("./zdaemon -Cconf start") . . daemon process started, pid=1139 >>> system("ls") conf zdaemon >>> import os >>> os.path.exists("/tmp/demo.zdsock".replace('/tmp', tmpdir)) True >>> system("./zdaemon -Cconf stop") . . daemon process stopped In the example, we included a command-line argument in the program option. We can also provide options on the command line: >>> open('conf', 'w').write( ... ''' ... ... program sleep ... socket-name /tmp/demo.zdsock ... ... '''.replace('/tmp', tmpdir)) >>> system("./zdaemon -Cconf start 100") . . daemon process started, pid=1149 >>> system("./zdaemon -Cconf status") program running; pid=1149 >>> system("./zdaemon -Cconf stop") . . daemon process stopped Environment Variables ===================== Sometimes, it is necessary to set environment variables before running a program. Perhaps the most common case for this is setting LD_LIBRARY_PATH so that dynamically loaded libraries can be found. >>> open('conf', 'w').write( ... ''' ... ... program env ... socket-name /tmp/demo.zdsock ... ... ... LD_LIBRARY_PATH /home/foo/lib ... HOME /home/foo ... ... '''.replace('/tmp', tmpdir)) >>> system("./zdaemon -Cconf fg") env USER=jim HOME=/home/foo LOGNAME=jim USERNAME=jim TERM=dumb PATH=/home/jim/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin EMACS=t LANG=en_US.UTF-8 SHELL=/bin/bash EDITOR=emacs LD_LIBRARY_PATH=/home/foo/lib Transcript log ============== When zdaemon run a program in daemon mode, it disconnects the program's standard input, standard output, and standard error from the controlling terminal. It can optionally redirect the output to standard error and standard output to a file. This is done with the transcript option. This is, of course, useful for logging output from long-running applications. Let's look at an example. We'll have a long-running process that simple tails a data file: >>> f = open('data', 'w', 0) >>> import os >>> f.write('rec 1\n'); os.fsync(f.fileno()) >>> open('conf', 'w').write( ... ''' ... ... program tail -f data ... transcript log ... ... ''') >>> system("./zdaemon -Cconf start") . . daemon process started, pid=7963 .. Wait a little bit to make sure tail has a chance to work >>> import time >>> time.sleep(0.1) Now, if we look at the log file, it contains the tail output: >>> open('log').read() 'rec 1\n' We can rotate the transcript log by renaming it and telling zdaemon to reopen it: >>> import os >>> os.rename('log', 'log.1') If we generate more output: >>> f.write('rec 2\n'); os.fsync(f.fileno()) .. Wait a little bit to make sure tail has a chance to work >>> time.sleep(1) The output will appear in the old file, because zdaemon still has it open: >>> open('log.1').read() 'rec 1\nrec 2\n' Now, if we tell zdaemon to reopen the file: >>> system("./zdaemon -Cconf reopen_transcript") and generate some output: >>> f.write('rec 3\n'); os.fsync(f.fileno()) .. Wait a little bit to make sure tail has a chance to work >>> time.sleep(1) the output will show up in the new file, not the old: >>> open('log').read() 'rec 3\n' >>> open('log.1').read() 'rec 1\nrec 2\n' Reference Documentation ======================= The following options are available for use in the runner section of configuration files and as command-line options. program Command-line option: -p or --program This option gives the command used to start the subprocess managed by zdaemon. This is currently a simple list of whitespace-delimited words. The first word is the program file, subsequent words are its command line arguments. If the program file contains no slashes, it is searched using $PATH. (Note that there is no way to to include whitespace in the program file or an argument, and under certain circumstances other shell metacharacters are also a problem.) socket-name Command-line option: -s or --socket-name. The pathname of the Unix domain socket used for communication between the zdaemon command-line tool and a deamon-management process. The default is relative to the current directory in which zdaemon is started. You want to specify an absolute pathname here. This defaults to "zdsock", which is created in the directory in which zdrun is started. daemon Command-line option: -d or --daemon. If this option is true, zdaemon runs in the background as a true daemon. It forks a child process which becomes the subprocess manager, while the parent exits (making the shell that started it believe it is done). The child process also does the following: - if the directory option is set, change into that directory - redirect stdin, stdout and stderr to /dev/null - call setsid() so it becomes a session leader - call umask() with specified value The default for this option is on by default. The command-line option therefore has no effect. To disable daemon mode, you must use a configuration file:: program sleep 1 daemon off directory Command-line option: -z or --directory. If the daemon option is true (default), this option can specify a directory into which zdrun.py changes as part of the "daemonizing". If the daemon option is false, this option is ignored. backoff-limit Command-line option: -b or --backoff-limit. When the subprocess crashes, zdaemon inserts a one-second delay before it restarts it. When the subprocess crashes again right away, the delay is incremented by one second, and so on. What happens when the delay has reached the value of backoff-limit (in seconds), depends on the value of the forever option. If forever is false, zdaemon gives up at this point, and exits. An always-crashing subprocess will have been restarted exactly backoff-limit times in this case. If forever is true, zdaemon continues to attempt to restart the process, keeping the delay at backoff-limit seconds. If the subprocess stays up for more than backoff-limit seconds, the delay is reset to 1 second. This defaults to 10. forever Command-line option: -f or --forever. If this option is true, zdaemon will keep restarting a crashing subprocess forever. If it is false, it will give up after backoff-limit crashes in a row. See the description of backoff-limit for details. This is disabled by default. exit-codes Command-line option: -x or --exit-codes. This defaults to 0,2. If the subprocess exits with an exit status that is equal to one of the integers in this list, zdaemon will not restart it. The default list requires some explanation. Exit status 0 is considered a willful successful exit; the ZEO and Zope server processes use this exit status when they want to stop without being restarted. (Including in response to a SIGTERM.) Exit status 2 is typically issued for command line syntax errors; in this case, restarting the program will not help! NOTE: this mechanism overrides the backoff-limit and forever options; i.e. even if forever is true, a subprocess exit status code in this list makes zdaemon give up. To disable this, change the value to an empty list. user Command-line option: -u or --user. When zdaemon is started by root, this option specifies the user as who the the zdaemon process (and hence the daemon subprocess) will run. This can be a user name or a numeric user id. Both the user and the group are set from the corresponding password entry, using setuid() and setgid(). This is done before zdaemon does anything else besides parsing its command line arguments. NOTE: when zdaemon is not started by root, specifying this option is an error. (XXX This may be a mistake.) XXX The zdaemon event log file may be opened *before* setuid() is called. Is this good or bad? umask Command-line option: -m or --umask. When daemon mode is used, this option specifies the octal umask of the subprocess. default-to-interactive If this option is true, zdaemon enters interactive mode when it is invoked without a positional command argument. If it is false, you must use the -i or --interactive command line option to zdaemon to enter interactive mode. This is enabled by default. logfile This option specifies a log file that is the default target of the "logtail" zdaemon command. NOTE: This is NOT the log file to which zdaemon writes its logging messages! That log file is specified by the section described below. transcript The name of a file in which a transcript of all output from the command being run will be written to when daemonized. If not specified, output from the command will be discarded. This only takes effect when the "daemon" option is enabled. prompt The prompt shown by the controller program. The default must be provided by the application. (Note that a few other options are available to support old configuration files, but aren't needed any more and can generally be ignored.) In addition to the runner section, you can use an eventlog section that specified one or more logfile subsections:: path /var/log/foo/foo.log path STDOUT In this example, log output is sent to a file and to standard out. Log output from zdaemon usually isn't very interesting but can be handy for debugging. zope2.13-2.13.21/source/zdaemon/src/zdaemon/schema.xml0000644000175000017500000000176212214017516021307 0ustar arnauarnau This schema describes various options that control zdctl.py and zdrun.py. zdrun.py is the "daemon process manager"; it runs a subprocess in the background and restarts it when it crashes. zdctl.py is the user interface to zdrun.py; it can tell zdrun.py to start, stop or restart the subprocess, send it a signal, etc. There are two sections: <runner> defines options unique zdctl.py and zdrun.py, and <eventlog> defines a standard event logging section used by zdrun.py. More information about zdctl.py and zdrun.py can be found in the file Doc/zdctl.txt. This all is specific to Unix/Linux.

Exit codes: if at any point the application exits with an exit status listed by the -x option, it is not restarted. Any other form of termination (either being killed by a signal or exiting with an exit status not listed in the -x option) causes it to be restarted. Backoff limit: when the application exits (nearly) immediately after a restart, the daemon manager starts slowing down by delaying between restarts. The delay starts at 1 second and is increased by one on each restart up to the backoff limit given by the -b option; it is reset when the application runs for more than the backoff limit seconds. By default, when the delay reaches the backoff limit, the daemon manager exits (under the assumption that the application has a persistent fault). The -f (forever) option prevents this exit; use it when you expect that a temporary external problem (such as a network outage or an overfull disk) may prevent the application from starting but you want the daemon manager to keep trying.

A Folder contains other objects. Use Folders to organize your web objects in to logical groups.

A BTreeFolder2 may be able to handle a larger number of objects than a standard folder because it does not need to activate other subobjects in order to access a single subobject. It is more efficient than the original BTreeFolder product, but does not provide attribute access.

Home-page: http://pypi.python.org/pypi/Products.BTreeFolder2 Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: Overview ======== BTreeFolder2 is a Zope product that acts like a Zope 2 OFS folder but can store many more items. When you fill a Zope folder with too many items, both Zope and your browser get overwhelmed. Zope has to load and store a large folder object, and the browser has to render large HTML tables repeatedly. Zope can store a lot of objects, but it has trouble storing a lot of objects in a single standard folder. Zope Corporation once had an extensive discussion on the subject. It was decided that we would expand standard folders to handle large numbers of objects gracefully. Unfortunately, Zope folders are used and extended in so many ways today that it would be difficult to modify standard folders in a way that would be compatible with all Zope products. So the BTreeFolder product was born. It stored all subobjects in a ZODB BTree, a structure designed to allow many items without loading them all into memory. It also rendered the contents of the folder as a simple select list rather than a table. Most browsers have no trouble rendering large select lists. But there was still one issue remaining. BTreeFolders still stored the ID of all subobjects in a single database record. If you put tens of thousands of items in a single BTreeFolder, you would still be loading and storing a multi-megabyte folder object. Zope can do this, but not quickly, and not without bloating the database. BTreeFolder2 solves this issue. It stores not only the subobjects but also the IDs of the subobjects in a BTree. It also batches the list of items in the UI, showing only 1000 items at a time. So if you write your application carefully, you can use a BTreeFolder2 to store as many items as will fit in physical storage. There are products that depend on the internal structure of the original BTreeFolder, however. So rather than risk breaking those products, the product has been renamed. You can have both products installed at the same time. If you're developing new applications, you should use BTreeFolder2. Usage ===== The BTreeFolder2 user interface shows a list of items rather than a series of checkboxes. To visit an item, select it in the list and click the "edit" button. BTreeFolder2 objects provide Python dictionary-like methods to make them easier to use in Python code than standard folders:: has_key(key) keys() values() items() get(key, default=None) __len__() keys(), values(), and items() return sequences, but not necessarily tuples or lists. Use len(folder) to call the __len__() method. The objects returned by values() and items() have acquisition wrappers. BTreeFolder2 also provides a method for generating unique, non-overlapping IDs:: generateId(prefix='item', suffix='', rand_ceiling=999999999) The ID returned by this method is guaranteed to not clash with any other ID in the folder. Use the returned value as the ID for new objects. The generated IDs tend to be sequential so that objects that are likely related in some way get loaded together. BTreeFolder2 implements the full Folder interface, with the exception that the superValues() method does not return any items. To implement the method in the way the Zope codebase expects would undermine the performance benefits gained by using BTreeFolder2. Changelog ========= 2.13.4 (2011-12-12) ------------------- - Provide security declaration for `BTreeFolder2Base.hasObject` method. - Add some tests for correct `getattr` behavior. - Minor `__getattr__` and `_getOb` optimizations. 2.13.3 (2011-03-15) ------------------- - `keys`, `values` and `items` methods are now exactly the same as `objectIds`, `objectValues` and `objectItems`. They did the same before already but duplicated the code. 2.13.2 (2011-03-08) ------------------- - `objectValues` and `objectItems` no longer do a special handling when no special `spec` is requested as `objectIds` already does the correct handling. 2.13.1 (2010-08-04) ------------------- - Make sure that methods returning objects return them Acquisition wrapped. - Be more careful in calling our own keys, values and items methods, as sub-classes might have overridden some of them. 2.13.0 (2010-07-11) ------------------- - Changed the `objectIds`, `objectItems` and `objectValues` methods to use the internal OOBTree methods directly if no `spec` argument is passed. - Change implementation of `keys`, `items` and `values` method to access the `self._tree` OOBTree methods directly. This avoids lookups in the meta_types structures. - Implement the full dictionary protocol including `__getitem__`, `__delitem__`, `__setitem__`, `__nonzero__`, `__iter__` and `__contains__`. - Released as separate package.

Application code can generate events without being concerned about the event-processing frameworks that might handle the events. Events are objects that represent something happening in a system. They are used to extend processing by providing processing plug points.

Using the same virtualenv you set up to run the tests, you can build the docs: .. code-block:: sh $ /tmp/hack-zope.event/bin/easy_install Sphinx ... $ cd docs $ PATH=/tmp/hack-zope.event/bin:$PATH make html sphinx-build -b html -d _build/doctrees . _build/html ... build succeeded. Build finished. The HTML pages are in _build/html.

Doctest summary =============== 17 tests 0 failures in tests 0 failures in setup code build succeeded. Testing of doctests in the sources finished, look at the \ results in _build/doctest/output.txt. Running the tests using :mod:`zc.buildout` ------------------------------------------- :mod:`zope.event` ships with its own :file:`buildout.cfg` file and :file:`bootstrap.py` for setting up a development buildout: .. code-block:: sh $ /path/to/python2.6 bootstrap.py ... Generated script '.../bin/buildout' $ bin/buildout Develop: '/home/tseaver/projects/Zope/BTK/event/.' ... Generated script '.../bin/sphinx-quickstart'. Generated script '.../bin/sphinx-build'. You can now run the tests: .. code-block:: sh $ bin/test --all Running zope.testing.testrunner.layer.UnitTests tests: Set up zope.testing.testrunner.layer.UnitTests in 0.000 seconds. Ran 2 tests with 0 failures and 0 errors in 0.000 seconds. Tearing down left over layers: Tear down zope.testing.testrunner.layer.UnitTests in 0.000 seconds. Building the documentation using :mod:`zc.buildout` --------------------------------------------------- The :mod:`zope.event` buildout installs the Sphinx scripts required to build the documentation, including testing its code snippets: .. code-block:: sh $ cd docs $ PATH=../bin:$PATH make doctest html .../bin/sphinx-build -b doctest -d .../docs/_build/doctrees .../docs .../docs/_build/doctest running tests...

Build finished. The HTML pages are in .../docs/_build/html. Submitting a Bug Report ----------------------- :mod:`zope.event` tracks its bugs on Launchpad: https://bugs.launchpad.net/zope.event Please submit bug reports and feature requests there. Sharing Your Changes -------------------- .. note:: Please ensure that all tests are passing before you submit your code. If possible, your submission should include new tests for new features or bug fixes, although it is possible that you may have tested your new code by updating existing tests. If you got a read-only checkout from the Subversion repository, and you have made a change you would like to share, the best route is to let Subversion help you make a patch file: .. code-block:: sh $ svn diff > zope.event-cool_feature.patch You can then upload that patch file as an attachment to a Launchpad bug report. If you branched the code from Launchpad using Bazaar, you have another option: you can "push" your branch to Launchpad: .. code-block:: sh $ bzr push lp:~tseaver/zope.event/cool_feature After pushing your branch, you can link it to a bug report on Launchpad, or request that the maintainers merge your branch using the Launchpad "merge request" feature. zope2.13-2.13.21/source/zope.event/docs/usage.rst0000644000175000017500000000340312214017560020320 0ustar arnauarnauUsing :mod:`zope.event` ======================= The :mod:`zope.event` package has a list of subscribers. Application code can manage subscriptions by manipulating this list. For the examples here, we'll save the current contents away and empty the list. We'll restore the contents when we're done with our examples. .. doctest:: >>> import zope.event >>> old_subscribers = zope.event.subscribers[:] >>> del zope.event.subscribers[:] The package provides a :func:`notify` function, which is used to notify subscribers that something has happened: .. doctest:: >>> class MyEvent: ... pass >>> event = MyEvent() >>> zope.event.notify(event) The notify function is called with a single object, which we call an event. Any object will do: .. doctest:: >>> zope.event.notify(None) >>> zope.event.notify(42) An extremely trivial subscription mechanism is provided. Subscribers are simply callback functions: .. doctest:: >>> def f(event): ... print 'got:', event that are put into the subscriptions list: .. doctest:: >>> zope.event.subscribers.append(f) >>> zope.event.notify(42) got: 42 >>> def g(event): ... print 'also got:', event >>> zope.event.subscribers.append(g) >>> zope.event.notify(42) got: 42 also got: 42 To unsubscribe, simply remove a subscriber from the list: .. doctest:: >>> zope.event.subscribers.remove(f) >>> zope.event.notify(42) also got: 42 Generally, application frameworks will provide more sophisticated subscription mechanisms that build on this simple mechanism. The frameworks will install subscribers that then dispatch to other subscribers based on event types or data. We're done, so we'll restore the subscribers: .. doctest:: >>> zope.event.subscribers[:] = old_subscribers zope2.13-2.13.21/source/zope.event/docs/Makefile0000644000175000017500000000607412214017560020131 0ustar arnauarnau# Makefile for Sphinx documentation # # You can set these variables from the command line.

It is maintained by the* `Zope Toolkit project `_. This package provides an implementation of `object interfaces` for Python. Interfaces are a mechanism for labeling objects as conforming to a given API or contract. So, this package can be considered as implementation of the `Design By Contract`_ methodology support in Python. .. _Design By Contract: http://en.wikipedia.org/wiki/Design_by_contract Detailed Documentation ********************** .. contents:: ========== Interfaces ========== Interfaces are objects that specify (document) the external behavior of objects that "provide" them. An interface specifies behavior through: - Informal documentation in a doc string - Attribute definitions - Invariants, which are conditions that must hold for objects that provide the interface Attribute definitions specify specific attributes. They define the attribute name and provide documentation and constraints of attribute values. Attribute definitions can take a number of forms, as we'll see below. Defining interfaces =================== Interfaces are defined using Python class statements:: >>> import zope.interface >>> class IFoo(zope.interface.Interface): ... """Foo blah blah""" ... ... x = zope.interface.Attribute("""X blah blah""") ... ... def bar(q, r=None): ... """bar blah blah""" In the example above, we've created an interface, `IFoo`. We subclassed `zope.interface.Interface`, which is an ancestor interface for all interfaces, much as `object` is an ancestor of all new-style classes [#create]_. The interface is not a class, it's an Interface, an instance of `InterfaceClass`:: >>> type(IFoo) We can ask for the interface's documentation:: >>> IFoo.__doc__ 'Foo blah blah' and its name:: >>> IFoo.__name__ 'IFoo' and even its module:: >>> IFoo.__module__ '__main__' The interface defined two attributes: `x` This is the simplest form of attribute definition. It has a name and a doc string. It doesn't formally specify anything else. `bar` This is a method. A method is defined via a function definition. A method is simply an attribute constrained to be a callable with a particular signature, as provided by the function definition. Note that `bar` doesn't take a `self` argument. Interfaces document how an object is *used*. When calling instance methods, you don't pass a `self` argument, so a `self` argument isn't included in the interface signature. The `self` argument in instance methods is really an implementation detail of Python instances. Other objects, besides instances can provide interfaces and their methods might not be instance methods. For example, modules can provide interfaces and their methods are usually just functions. Even instances can have methods that are not instance methods. You can access the attributes defined by an interface using mapping syntax:: >>> x = IFoo['x'] >>> type(x) >>> x.__name__ 'x' >>> x.__doc__ 'X blah blah' >>> IFoo.get('x').__name__ 'x' >>> IFoo.get('y') You can use `in` to determine if an interface defines a name:: >>> 'x' in IFoo True You can iterate over interfaces to get the names they define:: >>> names = list(IFoo) >>> names.sort() >>> names ['bar', 'x'] Remember that interfaces aren't classes. You can't access attribute definitions as attributes of interfaces:: >>> IFoo.x Traceback (most recent call last): File "", line 1, in ? AttributeError: 'InterfaceClass' object has no attribute 'x' Methods provide access to the method signature:: >>> bar = IFoo['bar'] >>> bar.getSignatureString() '(q, r=None)' TODO Methods really should have a better API. This is something that needs to be improved. Declaring interfaces ==================== Having defined interfaces, we can *declare* that objects provide them. Before we describe the details, lets define some terms: *provide* We say that objects *provide* interfaces. If an object provides an interface, then the interface specifies the behavior of the object. In other words, interfaces specify the behavior of the objects that provide them. *implement* We normally say that classes *implement* interfaces. If a class implements an interface, then the instances of the class provide the interface. Objects provide interfaces that their classes implement [#factory]_. (Objects can provide interfaces directly, in addition to what their classes implement.) It is important to note that classes don't usually provide the interfaces that they implement. We can generalize this to factories. For any callable object we can declare that it produces objects that provide some interfaces by saying that the factory implements the interfaces. Now that we've defined these terms, we can talk about the API for declaring interfaces. Declaring implemented interfaces -------------------------------- The most common way to declare interfaces is using the implements function in a class statement:: >>> class Foo: ... zope.interface.implements(IFoo) ... ... def __init__(self, x=None): ... self.x = x ... ... def bar(self, q, r=None): ... return q, r, self.x ... ... def __repr__(self): ... return "Foo(%s)" % self.x In this example, we declared that `Foo` implements `IFoo`. This means that instances of `Foo` provide `IFoo`. Having made this declaration, there are several ways we can introspect the declarations. First, we can ask an interface whether it is implemented by a class:: >>> IFoo.implementedBy(Foo) True And we can ask whether an interface is provided by an object:: >>> foo = Foo() >>> IFoo.providedBy(foo) True Of course, `Foo` doesn't provide `IFoo`, it implements it:: >>> IFoo.providedBy(Foo) False We can also ask what interfaces are implemented by an object:: >>> list(zope.interface.implementedBy(Foo)) [] It's an error to ask for interfaces implemented by a non-callable object:: >>> IFoo.implementedBy(foo) Traceback (most recent call last): ... TypeError: ('ImplementedBy called for non-factory', Foo(None)) >>> list(zope.interface.implementedBy(foo)) Traceback (most recent call last): ... TypeError: ('ImplementedBy called for non-factory', Foo(None)) Similarly, we can ask what interfaces are provided by an object:: >>> list(zope.interface.providedBy(foo)) [] >>> list(zope.interface.providedBy(Foo)) [] We can declare interfaces implemented by other factories (besides classes). We do this using a Python-2.4-style decorator named `implementer`. In versions of Python before 2.4, this looks like:: >>> def yfoo(y): ... foo = Foo() ... foo.y = y ... return foo >>> yfoo = zope.interface.implementer(IFoo)(yfoo) >>> list(zope.interface.implementedBy(yfoo)) [] Note that the implementer decorator may modify it's argument. Callers should not assume that a new object is created. Using implementer also works on callable objects. This is used by zope.formlib, as an example. >>> class yfactory: ... def __call__(self, y): ... foo = Foo() ... foo.y = y ... return foo >>> yfoo = yfactory() >>> yfoo = zope.interface.implementer(IFoo)(yfoo) >>> list(zope.interface.implementedBy(yfoo)) [] XXX: Double check and update these version numbers: In zope.interface 3.5.2 and lower, the implementor decorator can not be used for classes, but in 3.6.0 and higher it can: >>> Foo = zope.interface.implementer(IFoo)(Foo) >>> list(zope.interface.providedBy(Foo())) [] Note that class decorators using the @implementor(IFoo) syntax are only supported in Python 2.6 and later. Declaring provided interfaces ----------------------------- We can declare interfaces directly provided by objects. Suppose that we want to document what the `__init__` method of the `Foo` class does. It's not *really* part of `IFoo`. You wouldn't normally call the `__init__` method on Foo instances. Rather, the `__init__` method is part of the `Foo`'s `__call__` method:: >>> class IFooFactory(zope.interface.Interface): ... """Create foos""" ... ... def __call__(x=None): ... """Create a foo ... ... The argument provides the initial value for x ... ... """ It's the class that provides this interface, so we declare the interface on the class:: >>> zope.interface.directlyProvides(Foo, IFooFactory) And then, we'll see that Foo provides some interfaces:: >>> list(zope.interface.providedBy(Foo)) [] >>> IFooFactory.providedBy(Foo) True Declaring class interfaces is common enough that there's a special declaration function for it, `classProvides`, that allows the declaration from within a class statement:: >>> class Foo2: ... zope.interface.implements(IFoo) ... zope.interface.classProvides(IFooFactory) ... ... def __init__(self, x=None): ... self.x = x ... ... def bar(self, q, r=None): ... return q, r, self.x ... ... def __repr__(self): ... return "Foo(%s)" % self.x >>> list(zope.interface.providedBy(Foo2)) [] >>> IFooFactory.providedBy(Foo2) True There's a similar function, `moduleProvides`, that supports interface declarations from within module definitions. For example, see the use of `moduleProvides` call in `zope.interface.__init__`, which declares that the package `zope.interface` provides `IInterfaceDeclaration`. Sometimes, we want to declare interfaces on instances, even though those instances get interfaces from their classes. Suppose we create a new interface, `ISpecial`:: >>> class ISpecial(zope.interface.Interface): ... reason = zope.interface.Attribute("Reason why we're special") ... def brag(): ... "Brag about being special" We can make an existing foo instance special by providing `reason` and `brag` attributes:: >>> foo.reason = 'I just am' >>> def brag(): ... return "I'm special!" >>> foo.brag = brag >>> foo.reason 'I just am' >>> foo.brag() "I'm special!" and by declaring the interface:: >>> zope.interface.directlyProvides(foo, ISpecial) then the new interface is included in the provided interfaces:: >>> ISpecial.providedBy(foo) True >>> list(zope.interface.providedBy(foo)) [, ] We can find out what interfaces are directly provided by an object:: >>> list(zope.interface.directlyProvidedBy(foo)) [] >>> newfoo = Foo() >>> list(zope.interface.directlyProvidedBy(newfoo)) [] Inherited declarations ---------------------- Normally, declarations are inherited:: >>> class SpecialFoo(Foo): ... zope.interface.implements(ISpecial) ... reason = 'I just am' ... def brag(self): ... return "I'm special because %s" % self.reason >>> list(zope.interface.implementedBy(SpecialFoo)) [, ] >>> list(zope.interface.providedBy(SpecialFoo())) [, ] Sometimes, you don't want to inherit declarations. In that case, you can use `implementsOnly`, instead of `implements`:: >>> class Special(Foo): ... zope.interface.implementsOnly(ISpecial) ... reason = 'I just am' ... def brag(self): ... return "I'm special because %s" % self.reason >>> list(zope.interface.implementedBy(Special)) [] >>> list(zope.interface.providedBy(Special())) [] External declarations --------------------- Normally, we make implementation declarations as part of a class definition. Sometimes, we may want to make declarations from outside the class definition. For example, we might want to declare interfaces for classes that we didn't write. The function `classImplements` can be used for this purpose:: >>> class C: ... pass >>> zope.interface.classImplements(C, IFoo) >>> list(zope.interface.implementedBy(C)) [] We can use `classImplementsOnly` to exclude inherited interfaces:: >>> class C(Foo): ... pass >>> zope.interface.classImplementsOnly(C, ISpecial) >>> list(zope.interface.implementedBy(C)) [] Declaration Objects ------------------- When we declare interfaces, we create *declaration* objects. When we query declarations, declaration objects are returned:: >>> type(zope.interface.implementedBy(Special)) Declaration objects and interface objects are similar in many ways. In fact, they share a common base class. The important thing to realize about them is that they can be used where interfaces are expected in declarations. Here's a silly example:: >>> class Special2(Foo): ... zope.interface.implementsOnly( ... zope.interface.implementedBy(Foo), ... ISpecial, ... ) ... reason = 'I just am' ... def brag(self): ... return "I'm special because %s" % self.reason The declaration here is almost the same as ``zope.interface.implements(ISpecial)``, except that the order of interfaces in the resulting declaration is different:: >>> list(zope.interface.implementedBy(Special2)) [, ] Interface Inheritance ===================== Interfaces can extend other interfaces. They do this simply by listing the other interfaces as base interfaces:: >>> class IBlat(zope.interface.Interface): ... """Blat blah blah""" ... ... y = zope.interface.Attribute("y blah blah") ... def eek(): ... """eek blah blah""" >>> IBlat.__bases__ (,) >>> class IBaz(IFoo, IBlat): ... """Baz blah""" ... def eek(a=1): ... """eek in baz blah""" ... >>> IBaz.__bases__ (, ) >>> names = list(IBaz) >>> names.sort() >>> names ['bar', 'eek', 'x', 'y'] Note that `IBaz` overrides eek:: >>> IBlat['eek'].__doc__ 'eek blah blah' >>> IBaz['eek'].__doc__ 'eek in baz blah' We were careful to override eek in a compatible way. When extending an interface, the extending interface should be compatible [#compat]_ with the extended interfaces. We can ask whether one interface extends another:: >>> IBaz.extends(IFoo) True >>> IBlat.extends(IFoo) False Note that interfaces don't extend themselves:: >>> IBaz.extends(IBaz) False Sometimes we wish they did, but we can, instead use `isOrExtends`:: >>> IBaz.isOrExtends(IBaz) True >>> IBaz.isOrExtends(IFoo) True >>> IFoo.isOrExtends(IBaz) False When we iterate over an interface, we get all of the names it defines, including names defined by base interfaces. Sometimes, we want *just* the names defined by the interface directly. We bane use the `names` method for that:: >>> list(IBaz.names()) ['eek'] Inheritance of attribute specifications --------------------------------------- An interface may override attribute definitions from base interfaces. If two base interfaces define the same attribute, the attribute is inherited from the most specific interface. For example, with:: >>> class IBase(zope.interface.Interface): ... ... def foo(): ... "base foo doc" >>> class IBase1(IBase): ... pass >>> class IBase2(IBase): ... ... def foo(): ... "base2 foo doc" >>> class ISub(IBase1, IBase2): ... pass ISub's definition of foo is the one from IBase2, since IBase2 is more specific that IBase:: >>> ISub['foo'].__doc__ 'base2 foo doc' Note that this differs from a depth-first search. Sometimes, it's useful to ask whether an interface defines an attribute directly. You can use the direct method to get a directly defined definitions:: >>> IBase.direct('foo').__doc__ 'base foo doc' >>> ISub.direct('foo') Specifications -------------- Interfaces and declarations are both special cases of specifications. What we described above for interface inheritance applies to both declarations and specifications. Declarations actually extend the interfaces that they declare:: >>> class Baz(object): ... zope.interface.implements(IBaz) >>> baz_implements = zope.interface.implementedBy(Baz) >>> baz_implements.__bases__ (, ) >>> baz_implements.extends(IFoo) True >>> baz_implements.isOrExtends(IFoo) True >>> baz_implements.isOrExtends(baz_implements) True Specifications (interfaces and declarations) provide an `__sro__` that lists the specification and all of it's ancestors:: >>> baz_implements.__sro__ (, , , , , ) Tagged Values ============= Interfaces and attribute descriptions support an extension mechanism, borrowed from UML, called "tagged values" that lets us store extra data:: >>> IFoo.setTaggedValue('date-modified', '2004-04-01') >>> IFoo.setTaggedValue('author', 'Jim Fulton') >>> IFoo.getTaggedValue('date-modified') '2004-04-01' >>> IFoo.queryTaggedValue('date-modified') '2004-04-01' >>> IFoo.queryTaggedValue('datemodified') >>> tags = list(IFoo.getTaggedValueTags()) >>> tags.sort() >>> tags ['author', 'date-modified'] Function attributes are converted to tagged values when method attribute definitions are created:: >>> class IBazFactory(zope.interface.Interface): ... def __call__(): ... "create one" ... __call__.return_type = IBaz >>> IBazFactory['__call__'].getTaggedValue('return_type') Tagged values can also be defined from within an interface definition:: >>> class IWithTaggedValues(zope.interface.Interface): ... zope.interface.taggedValue('squish', 'squash') >>> IWithTaggedValues.getTaggedValue('squish') 'squash' Invariants ========== Interfaces can express conditions that must hold for objects that provide them. These conditions are expressed using one or more invariants. Invariants are callable objects that will be called with an object that provides an interface. An invariant raises an `Invalid` exception if the condition doesn't hold. Here's an example:: >>> class RangeError(zope.interface.Invalid): ... """A range has invalid limits""" ... def __repr__(self): ... return "RangeError(%r)" % self.args >>> def range_invariant(ob): ... if ob.max < ob.min: ... raise RangeError(ob) Given this invariant, we can use it in an interface definition:: >>> class IRange(zope.interface.Interface): ... min = zope.interface.Attribute("Lower bound") ... max = zope.interface.Attribute("Upper bound") ... ... zope.interface.invariant(range_invariant) Interfaces have a method for checking their invariants:: >>> class Range(object): ... zope.interface.implements(IRange) ... ... def __init__(self, min, max): ... self.min, self.max = min, max ... ... def __repr__(self): ... return "Range(%s, %s)" % (self.min, self.max) >>> IRange.validateInvariants(Range(1,2)) >>> IRange.validateInvariants(Range(1,1)) >>> IRange.validateInvariants(Range(2,1)) Traceback (most recent call last): ... RangeError: Range(2, 1) If you have multiple invariants, you may not want to stop checking after the first error. If you pass a list to `validateInvariants`, then a single `Invalid` exception will be raised with the list of exceptions as it's argument:: >>> from zope.interface.exceptions import Invalid >>> errors = [] >>> try: ... IRange.validateInvariants(Range(2,1), errors) ... except Invalid, e: ... str(e) '[RangeError(Range(2, 1))]' And the list will be filled with the individual exceptions:: >>> errors [RangeError(Range(2, 1))] >>> del errors[:] Adaptation ========== Interfaces can be called to perform adaptation. The semantics are based on those of the PEP 246 adapt function. If an object cannot be adapted, then a TypeError is raised:: >>> class I(zope.interface.Interface): ... pass >>> I(0) Traceback (most recent call last): ... TypeError: ('Could not adapt', 0, ) unless an alternate value is provided as a second positional argument:: >>> I(0, 'bob') 'bob' If an object already implements the interface, then it will be returned:: >>> class C(object): ... zope.interface.implements(I) >>> obj = C() >>> I(obj) is obj True If an object implements __conform__, then it will be used:: >>> class C(object): ... zope.interface.implements(I) ... def __conform__(self, proto): ... return 0 >>> I(C()) 0 Adapter hooks (see __adapt__) will also be used, if present:: >>> from zope.interface.interface import adapter_hooks >>> def adapt_0_to_42(iface, obj): ... if obj == 0: ... return 42 >>> adapter_hooks.append(adapt_0_to_42) >>> I(0) 42 >>> adapter_hooks.remove(adapt_0_to_42) >>> I(0) Traceback (most recent call last): ... TypeError: ('Could not adapt', 0, ) __adapt__ --------- >>> class I(zope.interface.Interface): ... pass Interfaces implement the PEP 246 __adapt__ method. This method is normally not called directly. It is called by the PEP 246 adapt framework and by the interface __call__ operator. The adapt method is responsible for adapting an object to the reciever. The default version returns None:: >>> I.__adapt__(0) unless the object given provides the interface:: >>> class C(object): ... zope.interface.implements(I) >>> obj = C() >>> I.__adapt__(obj) is obj True Adapter hooks can be provided (or removed) to provide custom adaptation. We'll install a silly hook that adapts 0 to 42. We install a hook by simply adding it to the adapter_hooks list:: >>> from zope.interface.interface import adapter_hooks >>> def adapt_0_to_42(iface, obj): ... if obj == 0: ... return 42 >>> adapter_hooks.append(adapt_0_to_42) >>> I.__adapt__(0) 42 Hooks must either return an adapter, or None if no adapter can be found. Hooks can be uninstalled by removing them from the list:: >>> adapter_hooks.remove(adapt_0_to_42) >>> I.__adapt__(0) .. [#create] The main reason we subclass `Interface` is to cause the Python class statement to create an interface, rather than a class. It's possible to create interfaces by calling a special interface class directly. Doing this, it's possible (and, on rare occasions, useful) to create interfaces that don't descend from `Interface`. Using this technique is beyond the scope of this document. .. [#factory] Classes are factories. They can be called to create their instances. We expect that we will eventually extend the concept of implementation to other kinds of factories, so that we can declare the interfaces provided by the objects created. .. [#compat] The goal is substitutability. An object that provides an extending interface should be substitutable for an object that provides the extended interface. In our example, an object that provides IBaz should be usable whereever an object that provides IBlat is expected. The interface implementation doesn't enforce this. but maybe it should do some checks. ================ Adapter Registry ================ Adapter registries provide a way to register objects that depend on one or more interface specifications and provide (perhaps indirectly) some interface. In addition, the registrations have names. (You can think of the names as qualifiers of the provided interfaces.) The term "interface specification" refers both to interfaces and to interface declarations, such as declarations of interfaces implemented by a class. Single Adapters =============== Let's look at a simple example, using a single required specification:: >>> from zope.interface.adapter import AdapterRegistry >>> import zope.interface >>> class IR1(zope.interface.Interface): ... pass >>> class IP1(zope.interface.Interface): ... pass >>> class IP2(IP1): ... pass >>> registry = AdapterRegistry() We'll register an object that depends on IR1 and "provides" IP2:: >>> registry.register([IR1], IP2, '', 12) Given the registration, we can look it up again:: >>> registry.lookup([IR1], IP2, '') 12 Note that we used an integer in the example. In real applications, one would use some objects that actually depend on or provide interfaces. The registry doesn't care about what gets registered, so we'll use integers and strings to keep the examples simple. There is one exception. Registering a value of None unregisters any previously-registered value. If an object depends on a specification, it can be looked up with a specification that extends the specification that it depends on:: >>> class IR2(IR1): ... pass >>> registry.lookup([IR2], IP2, '') 12 We can use a class implementation specification to look up the object:: >>> class C2: ... zope.interface.implements(IR2) >>> registry.lookup([zope.interface.implementedBy(C2)], IP2, '') 12 and it can be looked up for interfaces that its provided interface extends:: >>> registry.lookup([IR1], IP1, '') 12 >>> registry.lookup([IR2], IP1, '') 12 But if you require a specification that doesn't extend the specification the object depends on, you won't get anything:: >>> registry.lookup([zope.interface.Interface], IP1, '') By the way, you can pass a default value to lookup:: >>> registry.lookup([zope.interface.Interface], IP1, '', 42) 42 If you try to get an interface the object doesn't provide, you also won't get anything:: >>> class IP3(IP2): ... pass >>> registry.lookup([IR1], IP3, '') You also won't get anything if you use the wrong name:: >>> registry.lookup([IR1], IP1, 'bob') >>> registry.register([IR1], IP2, 'bob', "Bob's 12") >>> registry.lookup([IR1], IP1, 'bob') "Bob's 12" You can leave the name off when doing a lookup:: >>> registry.lookup([IR1], IP1) 12 If we register an object that provides IP1:: >>> registry.register([IR1], IP1, '', 11) then that object will be prefered over O(12):: >>> registry.lookup([IR1], IP1, '') 11 Also, if we register an object for IR2, then that will be prefered when using IR2:: >>> registry.register([IR2], IP1, '', 21) >>> registry.lookup([IR2], IP1, '') 21 Finding out what, if anything, is registered -------------------------------------------- We can ask if there is an adapter registered for a collection of interfaces. This is different than lookup, because it looks for an exact match. >>> print registry.registered([IR1], IP1) 11 >>> print registry.registered([IR1], IP2) 12 >>> print registry.registered([IR1], IP2, 'bob') Bob's 12 >>> print registry.registered([IR2], IP1) 21 >>> print registry.registered([IR2], IP2) None In the last example, None was returned because nothing was registered exactly for the given interfaces. lookup1 ------- Lookup of single adapters is common enough that there is a specialized version of lookup that takes a single required interface:: >>> registry.lookup1(IR2, IP1, '') 21 >>> registry.lookup1(IR2, IP1) 21 Actual Adaptation ----------------- The adapter registry is intended to support adaptation, where one object that implements an interface is adapted to another object that supports a different interface. The adapter registry supports the computation of adapters. In this case, we have to register adapter factories:: >>> class IR(zope.interface.Interface): ... pass >>> class X: ... zope.interface.implements(IR) >>> class Y: ... zope.interface.implements(IP1) ... def __init__(self, context): ... self.context = context >>> registry.register([IR], IP1, '', Y) In this case, we registered a class as the factory. Now we can call `queryAdapter` to get the adapted object:: >>> x = X() >>> y = registry.queryAdapter(x, IP1) >>> y.__class__.__name__ 'Y' >>> y.context is x True We can register and lookup by name too:: >>> class Y2(Y): ... pass >>> registry.register([IR], IP1, 'bob', Y2) >>> y = registry.queryAdapter(x, IP1, 'bob') >>> y.__class__.__name__ 'Y2' >>> y.context is x True When the adapter factory produces `None`, then this is treated as if no adapter has been found. This allows us to prevent adaptation (when desired) and let the adapter factory determine whether adaptation is possible based on the state of the object being adapted. >>> def factory(context): ... if context.name == 'object': ... return 'adapter' ... return None >>> class Object(object): ... zope.interface.implements(IR) ... name = 'object' >>> registry.register([IR], IP1, 'conditional', factory) >>> obj = Object() >>> registry.queryAdapter(obj, IP1, 'conditional') 'adapter' >>> obj.name = 'no object' >>> registry.queryAdapter(obj, IP1, 'conditional') is None True >>> registry.queryAdapter(obj, IP1, 'conditional', 'default') 'default' An alternate method that provides the same function as `queryAdapter()` is `adapter_hook()`:: >>> y = registry.adapter_hook(IP1, x) >>> y.__class__.__name__ 'Y' >>> y.context is x True >>> y = registry.adapter_hook(IP1, x, 'bob') >>> y.__class__.__name__ 'Y2' >>> y.context is x True The `adapter_hook()` simply switches the order of the object and interface arguments. It is used to hook into the interface call mechanism. Default Adapters ---------------- Sometimes, you want to provide an adapter that will adapt anything. For that, provide None as the required interface:: >>> registry.register([None], IP1, '', 1) then we can use that adapter for interfaces we don't have specific adapters for:: >>> class IQ(zope.interface.Interface): ... pass >>> registry.lookup([IQ], IP1, '') 1 Of course, specific adapters are still used when applicable:: >>> registry.lookup([IR2], IP1, '') 21 Class adapters -------------- You can register adapters for class declarations, which is almost the same as registering them for a class:: >>> registry.register([zope.interface.implementedBy(C2)], IP1, '', 'C21') >>> registry.lookup([zope.interface.implementedBy(C2)], IP1, '') 'C21' Dict adapters ------------- At some point it was impossible to register dictionary-based adapters due a bug. Let's make sure this works now: >>> adapter = {} >>> registry.register((), IQ, '', adapter) >>> registry.lookup((), IQ, '') is adapter True Unregistering ------------- You can unregister by registering None, rather than an object:: >>> registry.register([zope.interface.implementedBy(C2)], IP1, '', None) >>> registry.lookup([zope.interface.implementedBy(C2)], IP1, '') 21 Of course, this means that None can't be registered. This is an exception to the statement, made earlier, that the registry doesn't care what gets registered. Multi-adapters ============== You can adapt multiple specifications:: >>> registry.register([IR1, IQ], IP2, '', '1q2') >>> registry.lookup([IR1, IQ], IP2, '') '1q2' >>> registry.lookup([IR2, IQ], IP1, '') '1q2' >>> class IS(zope.interface.Interface): ... pass >>> registry.lookup([IR2, IS], IP1, '') >>> class IQ2(IQ): ... pass >>> registry.lookup([IR2, IQ2], IP1, '') '1q2' >>> registry.register([IR1, IQ2], IP2, '', '1q22') >>> registry.lookup([IR2, IQ2], IP1, '') '1q22' Multi-adaptation ---------------- You can adapt multiple objects:: >>> class Q: ... zope.interface.implements(IQ) As with single adapters, we register a factory, which is often a class:: >>> class IM(zope.interface.Interface): ... pass >>> class M: ... zope.interface.implements(IM) ... def __init__(self, x, q): ... self.x, self.q = x, q >>> registry.register([IR, IQ], IM, '', M) And then we can call `queryMultiAdapter` to compute an adapter:: >>> q = Q() >>> m = registry.queryMultiAdapter((x, q), IM) >>> m.__class__.__name__ 'M' >>> m.x is x and m.q is q True and, of course, we can use names:: >>> class M2(M): ... pass >>> registry.register([IR, IQ], IM, 'bob', M2) >>> m = registry.queryMultiAdapter((x, q), IM, 'bob') >>> m.__class__.__name__ 'M2' >>> m.x is x and m.q is q True Default Adapters ---------------- As with single adapters, you can define default adapters by specifying None for the *first* specification:: >>> registry.register([None, IQ], IP2, '', 'q2') >>> registry.lookup([IS, IQ], IP2, '') 'q2' Null Adapters ============= You can also adapt no specification:: >>> registry.register([], IP2, '', 2) >>> registry.lookup([], IP2, '') 2 >>> registry.lookup([], IP1, '') 2 Listing named adapters ---------------------- Adapters are named. Sometimes, it's useful to get all of the named adapters for given interfaces:: >>> adapters = list(registry.lookupAll([IR1], IP1)) >>> adapters.sort() >>> assert adapters == [(u'', 11), (u'bob', "Bob's 12")] This works for multi-adapters too:: >>> registry.register([IR1, IQ2], IP2, 'bob', '1q2 for bob') >>> adapters = list(registry.lookupAll([IR2, IQ2], IP1)) >>> adapters.sort() >>> assert adapters == [(u'', '1q22'), (u'bob', '1q2 for bob')] And even null adapters:: >>> registry.register([], IP2, 'bob', 3) >>> adapters = list(registry.lookupAll([], IP1)) >>> adapters.sort() >>> assert adapters == [(u'', 2), (u'bob', 3)] Subscriptions ============= Normally, we want to look up an object that most-closely matches a specification. Sometimes, we want to get all of the objects that match some specification. We use subscriptions for this. We subscribe objects against specifications and then later find all of the subscribed objects:: >>> registry.subscribe([IR1], IP2, 'sub12 1') >>> registry.subscriptions([IR1], IP2) ['sub12 1'] Note that, unlike regular adapters, subscriptions are unnamed. You can have multiple subscribers for the same specification:: >>> registry.subscribe([IR1], IP2, 'sub12 2') >>> registry.subscriptions([IR1], IP2) ['sub12 1', 'sub12 2'] If subscribers are registered for the same required interfaces, they are returned in the order of definition. You can register subscribers for all specifications using None:: >>> registry.subscribe([None], IP1, 'sub_1') >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2'] Note that the new subscriber is returned first. Subscribers defined for less general required interfaces are returned before subscribers for more general interfaces. Subscriptions may be combined over multiple compatible specifications:: >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2'] >>> registry.subscribe([IR1], IP1, 'sub11') >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2', 'sub11'] >>> registry.subscribe([IR2], IP2, 'sub22') >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2', 'sub11', 'sub22'] >>> registry.subscriptions([IR2], IP2) ['sub12 1', 'sub12 2', 'sub22'] Subscriptions can be on multiple specifications:: >>> registry.subscribe([IR1, IQ], IP2, 'sub1q2') >>> registry.subscriptions([IR1, IQ], IP2) ['sub1q2'] As with single subscriptions and non-subscription adapters, you can specify None for the first required interface, to specify a default:: >>> registry.subscribe([None, IQ], IP2, 'sub_q2') >>> registry.subscriptions([IS, IQ], IP2) ['sub_q2'] >>> registry.subscriptions([IR1, IQ], IP2) ['sub_q2', 'sub1q2'] You can have subscriptions that are indepenent of any specifications:: >>> list(registry.subscriptions([], IP1)) [] >>> registry.subscribe([], IP2, 'sub2') >>> registry.subscriptions([], IP1) ['sub2'] >>> registry.subscribe([], IP1, 'sub1') >>> registry.subscriptions([], IP1) ['sub2', 'sub1'] >>> registry.subscriptions([], IP2) ['sub2'] Unregistering subscribers ------------------------- We can unregister subscribers. When unregistering a subscriber, we can unregister a specific subscriber:: >>> registry.unsubscribe([IR1], IP1, 'sub11') >>> registry.subscriptions([IR1], IP1) ['sub_1', 'sub12 1', 'sub12 2'] If we don't specify a value, then all subscribers matching the given interfaces will be unsubscribed: >>> registry.unsubscribe([IR1], IP2) >>> registry.subscriptions([IR1], IP1) ['sub_1'] Subscription adapters --------------------- We normally register adapter factories, which then allow us to compute adapters, but with subscriptions, we get multiple adapters. Here's an example of multiple-object subscribers:: >>> registry.subscribe([IR, IQ], IM, M) >>> registry.subscribe([IR, IQ], IM, M2) >>> subscribers = registry.subscribers((x, q), IM) >>> len(subscribers) 2 >>> class_names = [s.__class__.__name__ for s in subscribers] >>> class_names.sort() >>> class_names ['M', 'M2'] >>> [(s.x is x and s.q is q) for s in subscribers] [True, True] adapter factory subcribers can't return None values:: >>> def M3(x, y): ... return None >>> registry.subscribe([IR, IQ], IM, M3) >>> subscribers = registry.subscribers((x, q), IM) >>> len(subscribers) 2 Handlers -------- A handler is a subscriber factory that doesn't produce any normal output. It returns None. A handler is unlike adapters in that it does all of its work when the factory is called. To register a handler, simply provide None as the provided interface:: >>> def handler(event): ... print 'handler', event >>> registry.subscribe([IR1], None, handler) >>> registry.subscriptions([IR1], None) == [handler] True ========================== Using the Adapter Registry ========================== This is a small demonstration of the ``zope.interface`` package including its adapter registry. It is intended to provide a concrete but narrow example on how to use interfaces and adapters outside of Zope 3. First we have to import the interface package:: >>> import zope.interface We now develop an interface for our object, which is a simple file in this case. For now we simply support one attribute, the body, which contains the actual file contents:: >>> class IFile(zope.interface.Interface): ... ... body = zope.interface.Attribute('Contents of the file.') ... For statistical reasons we often want to know the size of a file. However, it would be clumsy to implement the size directly in the file object, since the size really represents meta-data. Thus we create another interface that provides the size of something:: >>> class ISize(zope.interface.Interface): ... ... def getSize(): ... 'Return the size of an object.' ... Now we need to implement the file. It is essential that the object states that it implements the `IFile` interface. We also provide a default body value (just to make things simpler for this example):: >>> class File(object): ... ... zope.interface.implements(IFile) ... body = 'foo bar' ... Next we implement an adapter that can provide the `ISize` interface given any object providing `IFile`. By convention we use `__used_for__` to specify the interface that we expect the adapted object to provide, in our case `IFile`. However, this attribute is not used for anything. If you have multiple interfaces for which an adapter is used, just specify the interfaces via a tuple. Again by convention, the constructor of an adapter takes one argument, the context. The context in this case is an instance of `File` (providing `IFile`) that is used to extract the size from. Also by convention the context is stored in an attribute named `context` on the adapter. The twisted community refers to the context as the `original` object. However, you may feel free to use a specific argument name, such as `file`:: >>> class FileSize(object): ... ... zope.interface.implements(ISize) ... __used_for__ = IFile ... ... def __init__(self, context): ... self.context = context ... ... def getSize(self): ... return len(self.context.body) ... Now that we have written our adapter, we have to register it with an adapter registry, so that it can be looked up when needed. There is no such thing as a global registry; thus we have to instantiate one for our example manually:: >>> from zope.interface.adapter import AdapterRegistry >>> registry = AdapterRegistry() The registry keeps a map of what adapters implement based on another interface, the object already provides. Therefore, we next have to register an adapter that adapts from `IFile` to `ISize`. The first argument to the registry's `register()` method is a list of original interfaces.In our cause we have only one original interface, `IFile`. A list makes sense, since the interface package has the concept of multi-adapters, which are adapters that require multiple objects to adapt to a new interface. In these situations, your adapter constructor will require an argument for each specified interface. The second argument is the interface the adapter provides, in our case `ISize`. The third argument is the name of the adapter. Since we do not care about names, we simply leave it as an empty string. Names are commonly useful, if you have adapters for the same set of interfaces, but they are useful in different situations. The last argument is simply the adapter class:: >>> registry.register([IFile], ISize, '', FileSize) You can now use the the registry to lookup the adapter:: >>> registry.lookup1(IFile, ISize, '') Let's get a little bit more practical. Let's create a `File` instance and create the adapter using a registry lookup. Then we see whether the adapter returns the correct size by calling `getSize()`:: >>> file = File() >>> size = registry.lookup1(IFile, ISize, '')(file) >>> size.getSize() 7 However, this is not very practical, since I have to manually pass in the arguments to the lookup method. There is some syntactic candy that will allow us to get an adapter instance by simply calling `ISize(file)`. To make use of this functionality, we need to add our registry to the adapter_hooks list, which is a member of the adapters module. This list stores a collection of callables that are automatically invoked when IFoo(obj) is called; their purpose is to locate adapters that implement an interface for a certain context instance. You are required to implement your own adapter hook; this example covers one of the simplest hooks that use the registry, but you could implement one that used an adapter cache or persistent adapters, for instance. The helper hook is required to expect as first argument the desired output interface (for us `ISize`) and as the second argument the context of the adapter (here `file`). The function returns an adapter, i.e. a `FileSize` instance:: >>> def hook(provided, object): ... adapter = registry.lookup1(zope.interface.providedBy(object), ... provided, '') ... return adapter(object) ... We now just add the hook to an `adapter_hooks` list:: >>> from zope.interface.interface import adapter_hooks >>> adapter_hooks.append(hook) Once the hook is registered, you can use the desired syntax:: >>> size = ISize(file) >>> size.getSize() 7 Now we have to cleanup after ourselves, so that others after us have a clean `adapter_hooks` list:: >>> adapter_hooks.remove(hook) That's it. I have intentionally left out a discussion of named adapters and multi-adapters, since this text is intended as a practical and simple introduction to Zope 3 interfaces and adapters. You might want to read the `adapter.txt` in the `zope.interface` package for a more formal, referencial and complete treatment of the package. Warning: People have reported that `adapter.txt` makes their brain feel soft! ``zope.interface Changelog`` ============================ 3.6.7 (2011-08-20) ------------------ - Fix sporadic failures on x86-64 platforms in tests of rich comparisons of interfaces. 3.6.6 (2011-08-13) ------------------ - LP #570942: Now correctly compare interfaces from different modules but with the same names. N.B.: This is a less intrusive / destabilizing fix than the one applied in 3.6.3: we only fix the underlying cmp-alike function, rather than adding the other "rich comparison" functions. - Revert to software as released with 3.6.1 for "stable" 3.6 release branch. 3.6.5 (2011-08-11) ------------------ - LP #811792: work around buggy behavior in some subclasses of ``zope.interface.interface.InterfaceClass``, which invoke ``__hash__`` before initializing ``__module__`` and ``__name__``. The workaround returns a fixed constant hash in such cases, and issues a ``UserWarning``. - LP #804832: Under PyPy, ``zope.interface`` should not build its C extension. Also, prevent attempting to build it under Jython. - Add a tox.ini for easier xplatform testing. - Fix testing deprecation warnings issued when tested under Py3K. 3.6.4 (2011-07-04) ------------------ - LP 804951: InterfaceClass instances were unhashable under Python 3.x. 3.6.3 (2011-05-26) ------------------ - LP #570942: Now correctly compare interfaces from different modules but with the same names. 3.6.2 (2011-05-17) ------------------ - Moved detailed documentation out-of-line from PyPI page, linking instead to http://docs.zope.org/zope.interface . - Fixes for small issues when running tests under Python 3.2 using ``zope.testrunner``. - LP # 675064: Specify return value type for C optimizations module init under Python 3: undeclared value caused warnings, and segfaults on some 64 bit architectures. - setup.py now raises RuntimeError if you don't have Distutils installed when running under Python 3. 3.6.1 (2010-05-03) ------------------ - A non-ASCII character in the changelog made 3.6.0 uninstallable on Python 3 systems with another default encoding than UTF-8. - Fixed compiler warnings under GCC 4.3.3. 3.6.0 (2010-04-29) ------------------ - LP #185974: Clear the cache used by ``Specificaton.get`` inside ``Specification.changed``. Thanks to Jacob Holm for the patch. - Added support for Python 3.1. Contributors: Lennart Regebro Martin v Loewis Thomas Lotze Wolfgang Schnerring The 3.1 support is completely backwards compatible. However, the implements syntax used under Python 2.X does not work under 3.X, since it depends on how metaclasses are implemented and this has changed. Instead it now supports a decorator syntax (also under Python 2.X):: class Foo: implements(IFoo) ... can now also be written:: @implementor(IFoo): class Foo: ... There are 2to3 fixers available to do this change automatically in the zope.fixers package. - Python 2.3 is no longer supported. 3.5.4 (2009-12-23) ------------------ - Use the standard Python doctest module instead of zope.testing.doctest, which has been deprecated. 3.5.3 (2009-12-08) ------------------ - Fix an edge case: make providedBy() work when a class has '__provides__' in its __slots__ (see http://thread.gmane.org/gmane.comp.web.zope.devel/22490) 3.5.2 (2009-07-01) ------------------ - BaseAdapterRegistry.unregister, unsubscribe: Remove empty portions of the data structures when something is removed. This avoids leaving references to global objects (interfaces) that may be slated for removal from the calling application. 3.5.1 (2009-03-18) ------------------ - verifyObject: use getattr instead of hasattr to test for object attributes in order to let exceptions other than AttributeError raised by properties propagate to the caller - Add Sphinx-based documentation building to the package buildout configuration. Use the ``bin/docs`` command after buildout. - Improve package description a bit. Unify changelog entries formatting. - Change package's mailing list address to zope-dev at zope.org as zope3-dev at zope.org is now retired. 3.5.0 (2008-10-26) ------------------ - Fixed declaration of _zope_interface_coptimizations, it's not a top level package. - Add a DocTestSuite for odd.py module, so their tests are run. - Allow to bootstrap on Jython. - Fix https://bugs.launchpad.net/zope3/3.3/+bug/98388: ISpecification was missing a declaration for __iro__. - Added optional code optimizations support, which allows the building of C code optimizations to fail (Jython). - Replaced `_flatten` with a non-recursive implementation, effectively making it 3x faster. 3.4.1 (2007-10-02) ------------------ - Fixed a setup bug that prevented installation from source on systems without setuptools. 3.4.0 (2007-07-19) ------------------ - Final release for 3.4.0. 3.4.0b3 (2007-05-22) -------------------- - Objects with picky custom comparison methods couldn't be added to component registries. Now, when checking whether an object is already registered, identity comparison is used. 3.3.0.1 (2007-01-03) -------------------- - Made a reference to OverflowWarning, which disappeared in Python 2.5, conditional. 3.3.0 (2007/01/03) ------------------ New Features ++++++++++++ - The adapter-lookup algorithim was refactored to make it much simpler and faster. Also, more of the adapter-lookup logic is implemented in C, making debugging of application code easier, since there is less infrastructre code to step through. - We now treat objects without interface declarations as if they declared that they provide zope.interface.Interface. - There are a number of richer new adapter-registration interfaces that provide greater control and introspection. - Added a new interface decorator to zope.interface that allows the setting of tagged values on an interface at definition time (see zope.interface.taggedValue). Bug Fixes +++++++++ - A bug in multi-adapter lookup sometimes caused incorrect adapters to be returned. 3.2.0.2 (2006-04-15) -------------------- - Fix packaging bug: 'package_dir' must be a *relative* path. 3.2.0.1 (2006-04-14) -------------------- - Packaging change: suppress inclusion of 'setup.cfg' in 'sdist' builds. 3.2.0 (2006-01-05) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope 3.2.0 release. 3.1.0 (2005-10-03) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope 3.1.0 release. - Made attribute resolution order consistent with component lookup order, i.e. new-style class MRO semantics. - Deprecated 'isImplementedBy' and 'isImplementedByInstancesOf' APIs in favor of 'implementedBy' and 'providedBy'. 3.0.1 (2005-07-27) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope X3.0.1 release. - Fixed a bug reported by James Knight, which caused adapter registries to fail occasionally to reflect declaration changes. 3.0.0 (2004-11-07) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope X3.0.0 release.

It is maintained by the* `Zope Toolkit project `_. This package provides an implementation of `object interfaces` for Python. Interfaces are a mechanism for labeling objects as conforming to a given API or contract. So, this package can be considered as implementation of the `Design By Contract`_ methodology support in Python. .. _Design By Contract: http://en.wikipedia.org/wiki/Design_by_contract Detailed Documentation ********************** .. contents:: ========== Interfaces ========== Interfaces are objects that specify (document) the external behavior of objects that "provide" them. An interface specifies behavior through: - Informal documentation in a doc string - Attribute definitions - Invariants, which are conditions that must hold for objects that provide the interface Attribute definitions specify specific attributes. They define the attribute name and provide documentation and constraints of attribute values. Attribute definitions can take a number of forms, as we'll see below. Defining interfaces =================== Interfaces are defined using Python class statements:: >>> import zope.interface >>> class IFoo(zope.interface.Interface): ... """Foo blah blah""" ... ... x = zope.interface.Attribute("""X blah blah""") ... ... def bar(q, r=None): ... """bar blah blah""" In the example above, we've created an interface, `IFoo`. We subclassed `zope.interface.Interface`, which is an ancestor interface for all interfaces, much as `object` is an ancestor of all new-style classes [#create]_. The interface is not a class, it's an Interface, an instance of `InterfaceClass`:: >>> type(IFoo) We can ask for the interface's documentation:: >>> IFoo.__doc__ 'Foo blah blah' and its name:: >>> IFoo.__name__ 'IFoo' and even its module:: >>> IFoo.__module__ '__main__' The interface defined two attributes: `x` This is the simplest form of attribute definition. It has a name and a doc string. It doesn't formally specify anything else. `bar` This is a method. A method is defined via a function definition. A method is simply an attribute constrained to be a callable with a particular signature, as provided by the function definition. Note that `bar` doesn't take a `self` argument. Interfaces document how an object is *used*. When calling instance methods, you don't pass a `self` argument, so a `self` argument isn't included in the interface signature. The `self` argument in instance methods is really an implementation detail of Python instances. Other objects, besides instances can provide interfaces and their methods might not be instance methods. For example, modules can provide interfaces and their methods are usually just functions. Even instances can have methods that are not instance methods. You can access the attributes defined by an interface using mapping syntax:: >>> x = IFoo['x'] >>> type(x) >>> x.__name__ 'x' >>> x.__doc__ 'X blah blah' >>> IFoo.get('x').__name__ 'x' >>> IFoo.get('y') You can use `in` to determine if an interface defines a name:: >>> 'x' in IFoo True You can iterate over interfaces to get the names they define:: >>> names = list(IFoo) >>> names.sort() >>> names ['bar', 'x'] Remember that interfaces aren't classes. You can't access attribute definitions as attributes of interfaces:: >>> IFoo.x Traceback (most recent call last): File "", line 1, in ? AttributeError: 'InterfaceClass' object has no attribute 'x' Methods provide access to the method signature:: >>> bar = IFoo['bar'] >>> bar.getSignatureString() '(q, r=None)' TODO Methods really should have a better API. This is something that needs to be improved. Declaring interfaces ==================== Having defined interfaces, we can *declare* that objects provide them. Before we describe the details, lets define some terms: *provide* We say that objects *provide* interfaces. If an object provides an interface, then the interface specifies the behavior of the object. In other words, interfaces specify the behavior of the objects that provide them. *implement* We normally say that classes *implement* interfaces. If a class implements an interface, then the instances of the class provide the interface. Objects provide interfaces that their classes implement [#factory]_. (Objects can provide interfaces directly, in addition to what their classes implement.) It is important to note that classes don't usually provide the interfaces that they implement. We can generalize this to factories. For any callable object we can declare that it produces objects that provide some interfaces by saying that the factory implements the interfaces. Now that we've defined these terms, we can talk about the API for declaring interfaces. Declaring implemented interfaces -------------------------------- The most common way to declare interfaces is using the implements function in a class statement:: >>> class Foo: ... zope.interface.implements(IFoo) ... ... def __init__(self, x=None): ... self.x = x ... ... def bar(self, q, r=None): ... return q, r, self.x ... ... def __repr__(self): ... return "Foo(%s)" % self.x In this example, we declared that `Foo` implements `IFoo`. This means that instances of `Foo` provide `IFoo`. Having made this declaration, there are several ways we can introspect the declarations. First, we can ask an interface whether it is implemented by a class:: >>> IFoo.implementedBy(Foo) True And we can ask whether an interface is provided by an object:: >>> foo = Foo() >>> IFoo.providedBy(foo) True Of course, `Foo` doesn't provide `IFoo`, it implements it:: >>> IFoo.providedBy(Foo) False We can also ask what interfaces are implemented by an object:: >>> list(zope.interface.implementedBy(Foo)) [] It's an error to ask for interfaces implemented by a non-callable object:: >>> IFoo.implementedBy(foo) Traceback (most recent call last): ... TypeError: ('ImplementedBy called for non-factory', Foo(None)) >>> list(zope.interface.implementedBy(foo)) Traceback (most recent call last): ... TypeError: ('ImplementedBy called for non-factory', Foo(None)) Similarly, we can ask what interfaces are provided by an object:: >>> list(zope.interface.providedBy(foo)) [] >>> list(zope.interface.providedBy(Foo)) [] We can declare interfaces implemented by other factories (besides classes). We do this using a Python-2.4-style decorator named `implementer`. In versions of Python before 2.4, this looks like:: >>> def yfoo(y): ... foo = Foo() ... foo.y = y ... return foo >>> yfoo = zope.interface.implementer(IFoo)(yfoo) >>> list(zope.interface.implementedBy(yfoo)) [] Note that the implementer decorator may modify it's argument. Callers should not assume that a new object is created. Using implementer also works on callable objects. This is used by zope.formlib, as an example. >>> class yfactory: ... def __call__(self, y): ... foo = Foo() ... foo.y = y ... return foo >>> yfoo = yfactory() >>> yfoo = zope.interface.implementer(IFoo)(yfoo) >>> list(zope.interface.implementedBy(yfoo)) [] XXX: Double check and update these version numbers: In zope.interface 3.5.2 and lower, the implementor decorator can not be used for classes, but in 3.6.0 and higher it can: >>> Foo = zope.interface.implementer(IFoo)(Foo) >>> list(zope.interface.providedBy(Foo())) [] Note that class decorators using the @implementor(IFoo) syntax are only supported in Python 2.6 and later. Declaring provided interfaces ----------------------------- We can declare interfaces directly provided by objects. Suppose that we want to document what the `__init__` method of the `Foo` class does. It's not *really* part of `IFoo`. You wouldn't normally call the `__init__` method on Foo instances. Rather, the `__init__` method is part of the `Foo`'s `__call__` method:: >>> class IFooFactory(zope.interface.Interface): ... """Create foos""" ... ... def __call__(x=None): ... """Create a foo ... ... The argument provides the initial value for x ... ... """ It's the class that provides this interface, so we declare the interface on the class:: >>> zope.interface.directlyProvides(Foo, IFooFactory) And then, we'll see that Foo provides some interfaces:: >>> list(zope.interface.providedBy(Foo)) [] >>> IFooFactory.providedBy(Foo) True Declaring class interfaces is common enough that there's a special declaration function for it, `classProvides`, that allows the declaration from within a class statement:: >>> class Foo2: ... zope.interface.implements(IFoo) ... zope.interface.classProvides(IFooFactory) ... ... def __init__(self, x=None): ... self.x = x ... ... def bar(self, q, r=None): ... return q, r, self.x ... ... def __repr__(self): ... return "Foo(%s)" % self.x >>> list(zope.interface.providedBy(Foo2)) [] >>> IFooFactory.providedBy(Foo2) True There's a similar function, `moduleProvides`, that supports interface declarations from within module definitions. For example, see the use of `moduleProvides` call in `zope.interface.__init__`, which declares that the package `zope.interface` provides `IInterfaceDeclaration`. Sometimes, we want to declare interfaces on instances, even though those instances get interfaces from their classes. Suppose we create a new interface, `ISpecial`:: >>> class ISpecial(zope.interface.Interface): ... reason = zope.interface.Attribute("Reason why we're special") ... def brag(): ... "Brag about being special" We can make an existing foo instance special by providing `reason` and `brag` attributes:: >>> foo.reason = 'I just am' >>> def brag(): ... return "I'm special!" >>> foo.brag = brag >>> foo.reason 'I just am' >>> foo.brag() "I'm special!" and by declaring the interface:: >>> zope.interface.directlyProvides(foo, ISpecial) then the new interface is included in the provided interfaces:: >>> ISpecial.providedBy(foo) True >>> list(zope.interface.providedBy(foo)) [, ] We can find out what interfaces are directly provided by an object:: >>> list(zope.interface.directlyProvidedBy(foo)) [] >>> newfoo = Foo() >>> list(zope.interface.directlyProvidedBy(newfoo)) [] Inherited declarations ---------------------- Normally, declarations are inherited:: >>> class SpecialFoo(Foo): ... zope.interface.implements(ISpecial) ... reason = 'I just am' ... def brag(self): ... return "I'm special because %s" % self.reason >>> list(zope.interface.implementedBy(SpecialFoo)) [, ] >>> list(zope.interface.providedBy(SpecialFoo())) [, ] Sometimes, you don't want to inherit declarations. In that case, you can use `implementsOnly`, instead of `implements`:: >>> class Special(Foo): ... zope.interface.implementsOnly(ISpecial) ... reason = 'I just am' ... def brag(self): ... return "I'm special because %s" % self.reason >>> list(zope.interface.implementedBy(Special)) [] >>> list(zope.interface.providedBy(Special())) [] External declarations --------------------- Normally, we make implementation declarations as part of a class definition. Sometimes, we may want to make declarations from outside the class definition. For example, we might want to declare interfaces for classes that we didn't write. The function `classImplements` can be used for this purpose:: >>> class C: ... pass >>> zope.interface.classImplements(C, IFoo) >>> list(zope.interface.implementedBy(C)) [] We can use `classImplementsOnly` to exclude inherited interfaces:: >>> class C(Foo): ... pass >>> zope.interface.classImplementsOnly(C, ISpecial) >>> list(zope.interface.implementedBy(C)) [] Declaration Objects ------------------- When we declare interfaces, we create *declaration* objects. When we query declarations, declaration objects are returned:: >>> type(zope.interface.implementedBy(Special)) Declaration objects and interface objects are similar in many ways. In fact, they share a common base class. The important thing to realize about them is that they can be used where interfaces are expected in declarations. Here's a silly example:: >>> class Special2(Foo): ... zope.interface.implementsOnly( ... zope.interface.implementedBy(Foo), ... ISpecial, ... ) ... reason = 'I just am' ... def brag(self): ... return "I'm special because %s" % self.reason The declaration here is almost the same as ``zope.interface.implements(ISpecial)``, except that the order of interfaces in the resulting declaration is different:: >>> list(zope.interface.implementedBy(Special2)) [, ] Interface Inheritance ===================== Interfaces can extend other interfaces. They do this simply by listing the other interfaces as base interfaces:: >>> class IBlat(zope.interface.Interface): ... """Blat blah blah""" ... ... y = zope.interface.Attribute("y blah blah") ... def eek(): ... """eek blah blah""" >>> IBlat.__bases__ (,) >>> class IBaz(IFoo, IBlat): ... """Baz blah""" ... def eek(a=1): ... """eek in baz blah""" ... >>> IBaz.__bases__ (, ) >>> names = list(IBaz) >>> names.sort() >>> names ['bar', 'eek', 'x', 'y'] Note that `IBaz` overrides eek:: >>> IBlat['eek'].__doc__ 'eek blah blah' >>> IBaz['eek'].__doc__ 'eek in baz blah' We were careful to override eek in a compatible way. When extending an interface, the extending interface should be compatible [#compat]_ with the extended interfaces. We can ask whether one interface extends another:: >>> IBaz.extends(IFoo) True >>> IBlat.extends(IFoo) False Note that interfaces don't extend themselves:: >>> IBaz.extends(IBaz) False Sometimes we wish they did, but we can, instead use `isOrExtends`:: >>> IBaz.isOrExtends(IBaz) True >>> IBaz.isOrExtends(IFoo) True >>> IFoo.isOrExtends(IBaz) False When we iterate over an interface, we get all of the names it defines, including names defined by base interfaces. Sometimes, we want *just* the names defined by the interface directly. We bane use the `names` method for that:: >>> list(IBaz.names()) ['eek'] Inheritance of attribute specifications --------------------------------------- An interface may override attribute definitions from base interfaces. If two base interfaces define the same attribute, the attribute is inherited from the most specific interface. For example, with:: >>> class IBase(zope.interface.Interface): ... ... def foo(): ... "base foo doc" >>> class IBase1(IBase): ... pass >>> class IBase2(IBase): ... ... def foo(): ... "base2 foo doc" >>> class ISub(IBase1, IBase2): ... pass ISub's definition of foo is the one from IBase2, since IBase2 is more specific that IBase:: >>> ISub['foo'].__doc__ 'base2 foo doc' Note that this differs from a depth-first search. Sometimes, it's useful to ask whether an interface defines an attribute directly. You can use the direct method to get a directly defined definitions:: >>> IBase.direct('foo').__doc__ 'base foo doc' >>> ISub.direct('foo') Specifications -------------- Interfaces and declarations are both special cases of specifications. What we described above for interface inheritance applies to both declarations and specifications. Declarations actually extend the interfaces that they declare:: >>> class Baz(object): ... zope.interface.implements(IBaz) >>> baz_implements = zope.interface.implementedBy(Baz) >>> baz_implements.__bases__ (, ) >>> baz_implements.extends(IFoo) True >>> baz_implements.isOrExtends(IFoo) True >>> baz_implements.isOrExtends(baz_implements) True Specifications (interfaces and declarations) provide an `__sro__` that lists the specification and all of it's ancestors:: >>> baz_implements.__sro__ (, , , , , ) Tagged Values ============= Interfaces and attribute descriptions support an extension mechanism, borrowed from UML, called "tagged values" that lets us store extra data:: >>> IFoo.setTaggedValue('date-modified', '2004-04-01') >>> IFoo.setTaggedValue('author', 'Jim Fulton') >>> IFoo.getTaggedValue('date-modified') '2004-04-01' >>> IFoo.queryTaggedValue('date-modified') '2004-04-01' >>> IFoo.queryTaggedValue('datemodified') >>> tags = list(IFoo.getTaggedValueTags()) >>> tags.sort() >>> tags ['author', 'date-modified'] Function attributes are converted to tagged values when method attribute definitions are created:: >>> class IBazFactory(zope.interface.Interface): ... def __call__(): ... "create one" ... __call__.return_type = IBaz >>> IBazFactory['__call__'].getTaggedValue('return_type') Tagged values can also be defined from within an interface definition:: >>> class IWithTaggedValues(zope.interface.Interface): ... zope.interface.taggedValue('squish', 'squash') >>> IWithTaggedValues.getTaggedValue('squish') 'squash' Invariants ========== Interfaces can express conditions that must hold for objects that provide them. These conditions are expressed using one or more invariants. Invariants are callable objects that will be called with an object that provides an interface. An invariant raises an `Invalid` exception if the condition doesn't hold. Here's an example:: >>> class RangeError(zope.interface.Invalid): ... """A range has invalid limits""" ... def __repr__(self): ... return "RangeError(%r)" % self.args >>> def range_invariant(ob): ... if ob.max < ob.min: ... raise RangeError(ob) Given this invariant, we can use it in an interface definition:: >>> class IRange(zope.interface.Interface): ... min = zope.interface.Attribute("Lower bound") ... max = zope.interface.Attribute("Upper bound") ... ... zope.interface.invariant(range_invariant) Interfaces have a method for checking their invariants:: >>> class Range(object): ... zope.interface.implements(IRange) ... ... def __init__(self, min, max): ... self.min, self.max = min, max ... ... def __repr__(self): ... return "Range(%s, %s)" % (self.min, self.max) >>> IRange.validateInvariants(Range(1,2)) >>> IRange.validateInvariants(Range(1,1)) >>> IRange.validateInvariants(Range(2,1)) Traceback (most recent call last): ... RangeError: Range(2, 1) If you have multiple invariants, you may not want to stop checking after the first error. If you pass a list to `validateInvariants`, then a single `Invalid` exception will be raised with the list of exceptions as it's argument:: >>> from zope.interface.exceptions import Invalid >>> errors = [] >>> try: ... IRange.validateInvariants(Range(2,1), errors) ... except Invalid, e: ... str(e) '[RangeError(Range(2, 1))]' And the list will be filled with the individual exceptions:: >>> errors [RangeError(Range(2, 1))] >>> del errors[:] Adaptation ========== Interfaces can be called to perform adaptation. The semantics are based on those of the PEP 246 adapt function. If an object cannot be adapted, then a TypeError is raised:: >>> class I(zope.interface.Interface): ... pass >>> I(0) Traceback (most recent call last): ... TypeError: ('Could not adapt', 0, ) unless an alternate value is provided as a second positional argument:: >>> I(0, 'bob') 'bob' If an object already implements the interface, then it will be returned:: >>> class C(object): ... zope.interface.implements(I) >>> obj = C() >>> I(obj) is obj True If an object implements __conform__, then it will be used:: >>> class C(object): ... zope.interface.implements(I) ... def __conform__(self, proto): ... return 0 >>> I(C()) 0 Adapter hooks (see __adapt__) will also be used, if present:: >>> from zope.interface.interface import adapter_hooks >>> def adapt_0_to_42(iface, obj): ... if obj == 0: ... return 42 >>> adapter_hooks.append(adapt_0_to_42) >>> I(0) 42 >>> adapter_hooks.remove(adapt_0_to_42) >>> I(0) Traceback (most recent call last): ... TypeError: ('Could not adapt', 0, ) __adapt__ --------- >>> class I(zope.interface.Interface): ... pass Interfaces implement the PEP 246 __adapt__ method. This method is normally not called directly. It is called by the PEP 246 adapt framework and by the interface __call__ operator. The adapt method is responsible for adapting an object to the reciever. The default version returns None:: >>> I.__adapt__(0) unless the object given provides the interface:: >>> class C(object): ... zope.interface.implements(I) >>> obj = C() >>> I.__adapt__(obj) is obj True Adapter hooks can be provided (or removed) to provide custom adaptation. We'll install a silly hook that adapts 0 to 42. We install a hook by simply adding it to the adapter_hooks list:: >>> from zope.interface.interface import adapter_hooks >>> def adapt_0_to_42(iface, obj): ... if obj == 0: ... return 42 >>> adapter_hooks.append(adapt_0_to_42) >>> I.__adapt__(0) 42 Hooks must either return an adapter, or None if no adapter can be found. Hooks can be uninstalled by removing them from the list:: >>> adapter_hooks.remove(adapt_0_to_42) >>> I.__adapt__(0) .. [#create] The main reason we subclass `Interface` is to cause the Python class statement to create an interface, rather than a class. It's possible to create interfaces by calling a special interface class directly. Doing this, it's possible (and, on rare occasions, useful) to create interfaces that don't descend from `Interface`. Using this technique is beyond the scope of this document. .. [#factory] Classes are factories. They can be called to create their instances. We expect that we will eventually extend the concept of implementation to other kinds of factories, so that we can declare the interfaces provided by the objects created. .. [#compat] The goal is substitutability. An object that provides an extending interface should be substitutable for an object that provides the extended interface. In our example, an object that provides IBaz should be usable whereever an object that provides IBlat is expected. The interface implementation doesn't enforce this. but maybe it should do some checks. ================ Adapter Registry ================ Adapter registries provide a way to register objects that depend on one or more interface specifications and provide (perhaps indirectly) some interface. In addition, the registrations have names. (You can think of the names as qualifiers of the provided interfaces.) The term "interface specification" refers both to interfaces and to interface declarations, such as declarations of interfaces implemented by a class. Single Adapters =============== Let's look at a simple example, using a single required specification:: >>> from zope.interface.adapter import AdapterRegistry >>> import zope.interface >>> class IR1(zope.interface.Interface): ... pass >>> class IP1(zope.interface.Interface): ... pass >>> class IP2(IP1): ... pass >>> registry = AdapterRegistry() We'll register an object that depends on IR1 and "provides" IP2:: >>> registry.register([IR1], IP2, '', 12) Given the registration, we can look it up again:: >>> registry.lookup([IR1], IP2, '') 12 Note that we used an integer in the example. In real applications, one would use some objects that actually depend on or provide interfaces. The registry doesn't care about what gets registered, so we'll use integers and strings to keep the examples simple. There is one exception. Registering a value of None unregisters any previously-registered value. If an object depends on a specification, it can be looked up with a specification that extends the specification that it depends on:: >>> class IR2(IR1): ... pass >>> registry.lookup([IR2], IP2, '') 12 We can use a class implementation specification to look up the object:: >>> class C2: ... zope.interface.implements(IR2) >>> registry.lookup([zope.interface.implementedBy(C2)], IP2, '') 12 and it can be looked up for interfaces that its provided interface extends:: >>> registry.lookup([IR1], IP1, '') 12 >>> registry.lookup([IR2], IP1, '') 12 But if you require a specification that doesn't extend the specification the object depends on, you won't get anything:: >>> registry.lookup([zope.interface.Interface], IP1, '') By the way, you can pass a default value to lookup:: >>> registry.lookup([zope.interface.Interface], IP1, '', 42) 42 If you try to get an interface the object doesn't provide, you also won't get anything:: >>> class IP3(IP2): ... pass >>> registry.lookup([IR1], IP3, '') You also won't get anything if you use the wrong name:: >>> registry.lookup([IR1], IP1, 'bob') >>> registry.register([IR1], IP2, 'bob', "Bob's 12") >>> registry.lookup([IR1], IP1, 'bob') "Bob's 12" You can leave the name off when doing a lookup:: >>> registry.lookup([IR1], IP1) 12 If we register an object that provides IP1:: >>> registry.register([IR1], IP1, '', 11) then that object will be prefered over O(12):: >>> registry.lookup([IR1], IP1, '') 11 Also, if we register an object for IR2, then that will be prefered when using IR2:: >>> registry.register([IR2], IP1, '', 21) >>> registry.lookup([IR2], IP1, '') 21 Finding out what, if anything, is registered -------------------------------------------- We can ask if there is an adapter registered for a collection of interfaces. This is different than lookup, because it looks for an exact match. >>> print registry.registered([IR1], IP1) 11 >>> print registry.registered([IR1], IP2) 12 >>> print registry.registered([IR1], IP2, 'bob') Bob's 12 >>> print registry.registered([IR2], IP1) 21 >>> print registry.registered([IR2], IP2) None In the last example, None was returned because nothing was registered exactly for the given interfaces. lookup1 ------- Lookup of single adapters is common enough that there is a specialized version of lookup that takes a single required interface:: >>> registry.lookup1(IR2, IP1, '') 21 >>> registry.lookup1(IR2, IP1) 21 Actual Adaptation ----------------- The adapter registry is intended to support adaptation, where one object that implements an interface is adapted to another object that supports a different interface. The adapter registry supports the computation of adapters. In this case, we have to register adapter factories:: >>> class IR(zope.interface.Interface): ... pass >>> class X: ... zope.interface.implements(IR) >>> class Y: ... zope.interface.implements(IP1) ... def __init__(self, context): ... self.context = context >>> registry.register([IR], IP1, '', Y) In this case, we registered a class as the factory. Now we can call `queryAdapter` to get the adapted object:: >>> x = X() >>> y = registry.queryAdapter(x, IP1) >>> y.__class__.__name__ 'Y' >>> y.context is x True We can register and lookup by name too:: >>> class Y2(Y): ... pass >>> registry.register([IR], IP1, 'bob', Y2) >>> y = registry.queryAdapter(x, IP1, 'bob') >>> y.__class__.__name__ 'Y2' >>> y.context is x True When the adapter factory produces `None`, then this is treated as if no adapter has been found. This allows us to prevent adaptation (when desired) and let the adapter factory determine whether adaptation is possible based on the state of the object being adapted. >>> def factory(context): ... if context.name == 'object': ... return 'adapter' ... return None >>> class Object(object): ... zope.interface.implements(IR) ... name = 'object' >>> registry.register([IR], IP1, 'conditional', factory) >>> obj = Object() >>> registry.queryAdapter(obj, IP1, 'conditional') 'adapter' >>> obj.name = 'no object' >>> registry.queryAdapter(obj, IP1, 'conditional') is None True >>> registry.queryAdapter(obj, IP1, 'conditional', 'default') 'default' An alternate method that provides the same function as `queryAdapter()` is `adapter_hook()`:: >>> y = registry.adapter_hook(IP1, x) >>> y.__class__.__name__ 'Y' >>> y.context is x True >>> y = registry.adapter_hook(IP1, x, 'bob') >>> y.__class__.__name__ 'Y2' >>> y.context is x True The `adapter_hook()` simply switches the order of the object and interface arguments. It is used to hook into the interface call mechanism. Default Adapters ---------------- Sometimes, you want to provide an adapter that will adapt anything. For that, provide None as the required interface:: >>> registry.register([None], IP1, '', 1) then we can use that adapter for interfaces we don't have specific adapters for:: >>> class IQ(zope.interface.Interface): ... pass >>> registry.lookup([IQ], IP1, '') 1 Of course, specific adapters are still used when applicable:: >>> registry.lookup([IR2], IP1, '') 21 Class adapters -------------- You can register adapters for class declarations, which is almost the same as registering them for a class:: >>> registry.register([zope.interface.implementedBy(C2)], IP1, '', 'C21') >>> registry.lookup([zope.interface.implementedBy(C2)], IP1, '') 'C21' Dict adapters ------------- At some point it was impossible to register dictionary-based adapters due a bug. Let's make sure this works now: >>> adapter = {} >>> registry.register((), IQ, '', adapter) >>> registry.lookup((), IQ, '') is adapter True Unregistering ------------- You can unregister by registering None, rather than an object:: >>> registry.register([zope.interface.implementedBy(C2)], IP1, '', None) >>> registry.lookup([zope.interface.implementedBy(C2)], IP1, '') 21 Of course, this means that None can't be registered. This is an exception to the statement, made earlier, that the registry doesn't care what gets registered. Multi-adapters ============== You can adapt multiple specifications:: >>> registry.register([IR1, IQ], IP2, '', '1q2') >>> registry.lookup([IR1, IQ], IP2, '') '1q2' >>> registry.lookup([IR2, IQ], IP1, '') '1q2' >>> class IS(zope.interface.Interface): ... pass >>> registry.lookup([IR2, IS], IP1, '') >>> class IQ2(IQ): ... pass >>> registry.lookup([IR2, IQ2], IP1, '') '1q2' >>> registry.register([IR1, IQ2], IP2, '', '1q22') >>> registry.lookup([IR2, IQ2], IP1, '') '1q22' Multi-adaptation ---------------- You can adapt multiple objects:: >>> class Q: ... zope.interface.implements(IQ) As with single adapters, we register a factory, which is often a class:: >>> class IM(zope.interface.Interface): ... pass >>> class M: ... zope.interface.implements(IM) ... def __init__(self, x, q): ... self.x, self.q = x, q >>> registry.register([IR, IQ], IM, '', M) And then we can call `queryMultiAdapter` to compute an adapter:: >>> q = Q() >>> m = registry.queryMultiAdapter((x, q), IM) >>> m.__class__.__name__ 'M' >>> m.x is x and m.q is q True and, of course, we can use names:: >>> class M2(M): ... pass >>> registry.register([IR, IQ], IM, 'bob', M2) >>> m = registry.queryMultiAdapter((x, q), IM, 'bob') >>> m.__class__.__name__ 'M2' >>> m.x is x and m.q is q True Default Adapters ---------------- As with single adapters, you can define default adapters by specifying None for the *first* specification:: >>> registry.register([None, IQ], IP2, '', 'q2') >>> registry.lookup([IS, IQ], IP2, '') 'q2' Null Adapters ============= You can also adapt no specification:: >>> registry.register([], IP2, '', 2) >>> registry.lookup([], IP2, '') 2 >>> registry.lookup([], IP1, '') 2 Listing named adapters ---------------------- Adapters are named. Sometimes, it's useful to get all of the named adapters for given interfaces:: >>> adapters = list(registry.lookupAll([IR1], IP1)) >>> adapters.sort() >>> assert adapters == [(u'', 11), (u'bob', "Bob's 12")] This works for multi-adapters too:: >>> registry.register([IR1, IQ2], IP2, 'bob', '1q2 for bob') >>> adapters = list(registry.lookupAll([IR2, IQ2], IP1)) >>> adapters.sort() >>> assert adapters == [(u'', '1q22'), (u'bob', '1q2 for bob')] And even null adapters:: >>> registry.register([], IP2, 'bob', 3) >>> adapters = list(registry.lookupAll([], IP1)) >>> adapters.sort() >>> assert adapters == [(u'', 2), (u'bob', 3)] Subscriptions ============= Normally, we want to look up an object that most-closely matches a specification. Sometimes, we want to get all of the objects that match some specification. We use subscriptions for this. We subscribe objects against specifications and then later find all of the subscribed objects:: >>> registry.subscribe([IR1], IP2, 'sub12 1') >>> registry.subscriptions([IR1], IP2) ['sub12 1'] Note that, unlike regular adapters, subscriptions are unnamed. You can have multiple subscribers for the same specification:: >>> registry.subscribe([IR1], IP2, 'sub12 2') >>> registry.subscriptions([IR1], IP2) ['sub12 1', 'sub12 2'] If subscribers are registered for the same required interfaces, they are returned in the order of definition. You can register subscribers for all specifications using None:: >>> registry.subscribe([None], IP1, 'sub_1') >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2'] Note that the new subscriber is returned first. Subscribers defined for less general required interfaces are returned before subscribers for more general interfaces. Subscriptions may be combined over multiple compatible specifications:: >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2'] >>> registry.subscribe([IR1], IP1, 'sub11') >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2', 'sub11'] >>> registry.subscribe([IR2], IP2, 'sub22') >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2', 'sub11', 'sub22'] >>> registry.subscriptions([IR2], IP2) ['sub12 1', 'sub12 2', 'sub22'] Subscriptions can be on multiple specifications:: >>> registry.subscribe([IR1, IQ], IP2, 'sub1q2') >>> registry.subscriptions([IR1, IQ], IP2) ['sub1q2'] As with single subscriptions and non-subscription adapters, you can specify None for the first required interface, to specify a default:: >>> registry.subscribe([None, IQ], IP2, 'sub_q2') >>> registry.subscriptions([IS, IQ], IP2) ['sub_q2'] >>> registry.subscriptions([IR1, IQ], IP2) ['sub_q2', 'sub1q2'] You can have subscriptions that are indepenent of any specifications:: >>> list(registry.subscriptions([], IP1)) [] >>> registry.subscribe([], IP2, 'sub2') >>> registry.subscriptions([], IP1) ['sub2'] >>> registry.subscribe([], IP1, 'sub1') >>> registry.subscriptions([], IP1) ['sub2', 'sub1'] >>> registry.subscriptions([], IP2) ['sub2'] Unregistering subscribers ------------------------- We can unregister subscribers. When unregistering a subscriber, we can unregister a specific subscriber:: >>> registry.unsubscribe([IR1], IP1, 'sub11') >>> registry.subscriptions([IR1], IP1) ['sub_1', 'sub12 1', 'sub12 2'] If we don't specify a value, then all subscribers matching the given interfaces will be unsubscribed: >>> registry.unsubscribe([IR1], IP2) >>> registry.subscriptions([IR1], IP1) ['sub_1'] Subscription adapters --------------------- We normally register adapter factories, which then allow us to compute adapters, but with subscriptions, we get multiple adapters. Here's an example of multiple-object subscribers:: >>> registry.subscribe([IR, IQ], IM, M) >>> registry.subscribe([IR, IQ], IM, M2) >>> subscribers = registry.subscribers((x, q), IM) >>> len(subscribers) 2 >>> class_names = [s.__class__.__name__ for s in subscribers] >>> class_names.sort() >>> class_names ['M', 'M2'] >>> [(s.x is x and s.q is q) for s in subscribers] [True, True] adapter factory subcribers can't return None values:: >>> def M3(x, y): ... return None >>> registry.subscribe([IR, IQ], IM, M3) >>> subscribers = registry.subscribers((x, q), IM) >>> len(subscribers) 2 Handlers -------- A handler is a subscriber factory that doesn't produce any normal output. It returns None. A handler is unlike adapters in that it does all of its work when the factory is called. To register a handler, simply provide None as the provided interface:: >>> def handler(event): ... print 'handler', event >>> registry.subscribe([IR1], None, handler) >>> registry.subscriptions([IR1], None) == [handler] True ========================== Using the Adapter Registry ========================== This is a small demonstration of the ``zope.interface`` package including its adapter registry. It is intended to provide a concrete but narrow example on how to use interfaces and adapters outside of Zope 3. First we have to import the interface package:: >>> import zope.interface We now develop an interface for our object, which is a simple file in this case. For now we simply support one attribute, the body, which contains the actual file contents:: >>> class IFile(zope.interface.Interface): ... ... body = zope.interface.Attribute('Contents of the file.') ... For statistical reasons we often want to know the size of a file. However, it would be clumsy to implement the size directly in the file object, since the size really represents meta-data. Thus we create another interface that provides the size of something:: >>> class ISize(zope.interface.Interface): ... ... def getSize(): ... 'Return the size of an object.' ... Now we need to implement the file. It is essential that the object states that it implements the `IFile` interface. We also provide a default body value (just to make things simpler for this example):: >>> class File(object): ... ... zope.interface.implements(IFile) ... body = 'foo bar' ... Next we implement an adapter that can provide the `ISize` interface given any object providing `IFile`. By convention we use `__used_for__` to specify the interface that we expect the adapted object to provide, in our case `IFile`. However, this attribute is not used for anything. If you have multiple interfaces for which an adapter is used, just specify the interfaces via a tuple. Again by convention, the constructor of an adapter takes one argument, the context. The context in this case is an instance of `File` (providing `IFile`) that is used to extract the size from. Also by convention the context is stored in an attribute named `context` on the adapter. The twisted community refers to the context as the `original` object. However, you may feel free to use a specific argument name, such as `file`:: >>> class FileSize(object): ... ... zope.interface.implements(ISize) ... __used_for__ = IFile ... ... def __init__(self, context): ... self.context = context ... ... def getSize(self): ... return len(self.context.body) ... Now that we have written our adapter, we have to register it with an adapter registry, so that it can be looked up when needed. There is no such thing as a global registry; thus we have to instantiate one for our example manually:: >>> from zope.interface.adapter import AdapterRegistry >>> registry = AdapterRegistry() The registry keeps a map of what adapters implement based on another interface, the object already provides. Therefore, we next have to register an adapter that adapts from `IFile` to `ISize`. The first argument to the registry's `register()` method is a list of original interfaces.In our cause we have only one original interface, `IFile`. A list makes sense, since the interface package has the concept of multi-adapters, which are adapters that require multiple objects to adapt to a new interface. In these situations, your adapter constructor will require an argument for each specified interface. The second argument is the interface the adapter provides, in our case `ISize`. The third argument is the name of the adapter. Since we do not care about names, we simply leave it as an empty string. Names are commonly useful, if you have adapters for the same set of interfaces, but they are useful in different situations. The last argument is simply the adapter class:: >>> registry.register([IFile], ISize, '', FileSize) You can now use the the registry to lookup the adapter:: >>> registry.lookup1(IFile, ISize, '') Let's get a little bit more practical. Let's create a `File` instance and create the adapter using a registry lookup. Then we see whether the adapter returns the correct size by calling `getSize()`:: >>> file = File() >>> size = registry.lookup1(IFile, ISize, '')(file) >>> size.getSize() 7 However, this is not very practical, since I have to manually pass in the arguments to the lookup method. There is some syntactic candy that will allow us to get an adapter instance by simply calling `ISize(file)`. To make use of this functionality, we need to add our registry to the adapter_hooks list, which is a member of the adapters module. This list stores a collection of callables that are automatically invoked when IFoo(obj) is called; their purpose is to locate adapters that implement an interface for a certain context instance. You are required to implement your own adapter hook; this example covers one of the simplest hooks that use the registry, but you could implement one that used an adapter cache or persistent adapters, for instance. The helper hook is required to expect as first argument the desired output interface (for us `ISize`) and as the second argument the context of the adapter (here `file`). The function returns an adapter, i.e. a `FileSize` instance:: >>> def hook(provided, object): ... adapter = registry.lookup1(zope.interface.providedBy(object), ... provided, '') ... return adapter(object) ... We now just add the hook to an `adapter_hooks` list:: >>> from zope.interface.interface import adapter_hooks >>> adapter_hooks.append(hook) Once the hook is registered, you can use the desired syntax:: >>> size = ISize(file) >>> size.getSize() 7 Now we have to cleanup after ourselves, so that others after us have a clean `adapter_hooks` list:: >>> adapter_hooks.remove(hook) That's it. I have intentionally left out a discussion of named adapters and multi-adapters, since this text is intended as a practical and simple introduction to Zope 3 interfaces and adapters. You might want to read the `adapter.txt` in the `zope.interface` package for a more formal, referencial and complete treatment of the package. Warning: People have reported that `adapter.txt` makes their brain feel soft! ``zope.interface Changelog`` ============================ 3.6.7 (2011-08-20) ------------------ - Fix sporadic failures on x86-64 platforms in tests of rich comparisons of interfaces. 3.6.6 (2011-08-13) ------------------ - LP #570942: Now correctly compare interfaces from different modules but with the same names. N.B.: This is a less intrusive / destabilizing fix than the one applied in 3.6.3: we only fix the underlying cmp-alike function, rather than adding the other "rich comparison" functions. - Revert to software as released with 3.6.1 for "stable" 3.6 release branch. 3.6.5 (2011-08-11) ------------------ - LP #811792: work around buggy behavior in some subclasses of ``zope.interface.interface.InterfaceClass``, which invoke ``__hash__`` before initializing ``__module__`` and ``__name__``. The workaround returns a fixed constant hash in such cases, and issues a ``UserWarning``. - LP #804832: Under PyPy, ``zope.interface`` should not build its C extension. Also, prevent attempting to build it under Jython. - Add a tox.ini for easier xplatform testing. - Fix testing deprecation warnings issued when tested under Py3K. 3.6.4 (2011-07-04) ------------------ - LP 804951: InterfaceClass instances were unhashable under Python 3.x. 3.6.3 (2011-05-26) ------------------ - LP #570942: Now correctly compare interfaces from different modules but with the same names. 3.6.2 (2011-05-17) ------------------ - Moved detailed documentation out-of-line from PyPI page, linking instead to http://docs.zope.org/zope.interface . - Fixes for small issues when running tests under Python 3.2 using ``zope.testrunner``. - LP # 675064: Specify return value type for C optimizations module init under Python 3: undeclared value caused warnings, and segfaults on some 64 bit architectures. - setup.py now raises RuntimeError if you don't have Distutils installed when running under Python 3. 3.6.1 (2010-05-03) ------------------ - A non-ASCII character in the changelog made 3.6.0 uninstallable on Python 3 systems with another default encoding than UTF-8. - Fixed compiler warnings under GCC 4.3.3. 3.6.0 (2010-04-29) ------------------ - LP #185974: Clear the cache used by ``Specificaton.get`` inside ``Specification.changed``. Thanks to Jacob Holm for the patch. - Added support for Python 3.1. Contributors: Lennart Regebro Martin v Loewis Thomas Lotze Wolfgang Schnerring The 3.1 support is completely backwards compatible. However, the implements syntax used under Python 2.X does not work under 3.X, since it depends on how metaclasses are implemented and this has changed. Instead it now supports a decorator syntax (also under Python 2.X):: class Foo: implements(IFoo) ... can now also be written:: @implementor(IFoo): class Foo: ... There are 2to3 fixers available to do this change automatically in the zope.fixers package. - Python 2.3 is no longer supported. 3.5.4 (2009-12-23) ------------------ - Use the standard Python doctest module instead of zope.testing.doctest, which has been deprecated. 3.5.3 (2009-12-08) ------------------ - Fix an edge case: make providedBy() work when a class has '__provides__' in its __slots__ (see http://thread.gmane.org/gmane.comp.web.zope.devel/22490) 3.5.2 (2009-07-01) ------------------ - BaseAdapterRegistry.unregister, unsubscribe: Remove empty portions of the data structures when something is removed. This avoids leaving references to global objects (interfaces) that may be slated for removal from the calling application. 3.5.1 (2009-03-18) ------------------ - verifyObject: use getattr instead of hasattr to test for object attributes in order to let exceptions other than AttributeError raised by properties propagate to the caller - Add Sphinx-based documentation building to the package buildout configuration. Use the ``bin/docs`` command after buildout. - Improve package description a bit. Unify changelog entries formatting. - Change package's mailing list address to zope-dev at zope.org as zope3-dev at zope.org is now retired. 3.5.0 (2008-10-26) ------------------ - Fixed declaration of _zope_interface_coptimizations, it's not a top level package. - Add a DocTestSuite for odd.py module, so their tests are run. - Allow to bootstrap on Jython. - Fix https://bugs.launchpad.net/zope3/3.3/+bug/98388: ISpecification was missing a declaration for __iro__. - Added optional code optimizations support, which allows the building of C code optimizations to fail (Jython). - Replaced `_flatten` with a non-recursive implementation, effectively making it 3x faster. 3.4.1 (2007-10-02) ------------------ - Fixed a setup bug that prevented installation from source on systems without setuptools. 3.4.0 (2007-07-19) ------------------ - Final release for 3.4.0. 3.4.0b3 (2007-05-22) -------------------- - Objects with picky custom comparison methods couldn't be added to component registries. Now, when checking whether an object is already registered, identity comparison is used. 3.3.0.1 (2007-01-03) -------------------- - Made a reference to OverflowWarning, which disappeared in Python 2.5, conditional. 3.3.0 (2007/01/03) ------------------ New Features ++++++++++++ - The adapter-lookup algorithim was refactored to make it much simpler and faster. Also, more of the adapter-lookup logic is implemented in C, making debugging of application code easier, since there is less infrastructre code to step through. - We now treat objects without interface declarations as if they declared that they provide zope.interface.Interface. - There are a number of richer new adapter-registration interfaces that provide greater control and introspection. - Added a new interface decorator to zope.interface that allows the setting of tagged values on an interface at definition time (see zope.interface.taggedValue). Bug Fixes +++++++++ - A bug in multi-adapter lookup sometimes caused incorrect adapters to be returned. 3.2.0.2 (2006-04-15) -------------------- - Fix packaging bug: 'package_dir' must be a *relative* path. 3.2.0.1 (2006-04-14) -------------------- - Packaging change: suppress inclusion of 'setup.cfg' in 'sdist' builds. 3.2.0 (2006-01-05) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope 3.2.0 release. 3.1.0 (2005-10-03) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope 3.1.0 release. - Made attribute resolution order consistent with component lookup order, i.e. new-style class MRO semantics. - Deprecated 'isImplementedBy' and 'isImplementedByInstancesOf' APIs in favor of 'implementedBy' and 'providedBy'. 3.0.1 (2005-07-27) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope X3.0.1 release. - Fixed a bug reported by James Knight, which caused adapter registries to fail occasionally to reflect declaration changes. 3.0.0 (2004-11-07) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope X3.0.0 release.

It is maintained by the* `Zope Toolkit project `_. This package provides an implementation of `object interfaces` for Python. Interfaces are a mechanism for labeling objects as conforming to a given API or contract. So, this package can be considered as implementation of the `Design By Contract`_ methodology support in Python. .. _Design By Contract: http://en.wikipedia.org/wiki/Design_by_contract zope2.13-2.13.21/source/zope.interface/setup.cfg0000644000175000017500000000007312214017572020175 0ustar arnauarnau[egg_info] tag_build = tag_date = 0 tag_svn_revision = 0 zope2.13-2.13.21/source/zope.interface/build_ext_2.pyc0000644000175000017500000000277012214017572021277 0ustar arnauarnauó z0Rc@szddlZddlmZmZmZyddlmZWn!ek r_ddlmZnXdefd„ƒYZ dS(iÿÿÿÿN(tCCompilerErrortDistutilsExecErrortDistutilsPlatformError(t build_exttoptional_build_extcBs)eZdZd„Zd„Zd„ZRS(s\This class subclasses build_ext and allows the building of C extensions to fail. cCs8ytj|ƒWn tk r3}|j|ƒnXdS(N(RtrunRt _unavailable(tselfte((sbuild_ext_2.pyRscCsAytj||ƒWn&ttfk r<}|j|ƒnXdS(N(Rtbuild_extensionRRR(RtextR((sbuild_ext_2.pyR scCsGtjddIJtjdIJtjJtj|IJtjddIJdS(Nt*iPs“WARNING: An optional code optimization (C extension) could not be compiled.

N.B.: This is a less intrusive / destabilizing fix than the one applied in 3.6.3: we only fix the underlying cmp-alike function, rather than adding the other "rich comparison" functions. - Revert to software as released with 3.6.1 for "stable" 3.6 release branch. 3.6.5 (2011-08-11) ------------------ - LP #811792: work around buggy behavior in some subclasses of ``zope.interface.interface.InterfaceClass``, which invoke ``__hash__`` before initializing ``__module__`` and ``__name__``. The workaround returns a fixed constant hash in such cases, and issues a ``UserWarning``. - LP #804832: Under PyPy, ``zope.interface`` should not build its C extension. Also, prevent attempting to build it under Jython. - Add a tox.ini for easier xplatform testing. - Fix testing deprecation warnings issued when tested under Py3K. 3.6.4 (2011-07-04) ------------------ - LP 804951: InterfaceClass instances were unhashable under Python 3.x. 3.6.3 (2011-05-26) ------------------ - LP #570942: Now correctly compare interfaces from different modules but with the same names. 3.6.2 (2011-05-17) ------------------ - Moved detailed documentation out-of-line from PyPI page, linking instead to http://docs.zope.org/zope.interface . - Fixes for small issues when running tests under Python 3.2 using ``zope.testrunner``. - LP # 675064: Specify return value type for C optimizations module init under Python 3: undeclared value caused warnings, and segfaults on some 64 bit architectures. - setup.py now raises RuntimeError if you don't have Distutils installed when running under Python 3. 3.6.1 (2010-05-03) ------------------ - A non-ASCII character in the changelog made 3.6.0 uninstallable on Python 3 systems with another default encoding than UTF-8. - Fixed compiler warnings under GCC 4.3.3. 3.6.0 (2010-04-29) ------------------ - LP #185974: Clear the cache used by ``Specificaton.get`` inside ``Specification.changed``. Thanks to Jacob Holm for the patch. - Added support for Python 3.1. Contributors: Lennart Regebro Martin v Loewis Thomas Lotze Wolfgang Schnerring The 3.1 support is completely backwards compatible. However, the implements syntax used under Python 2.X does not work under 3.X, since it depends on how metaclasses are implemented and this has changed. Instead it now supports a decorator syntax (also under Python 2.X):: class Foo: implements(IFoo) ... can now also be written:: @implementor(IFoo): class Foo: ... There are 2to3 fixers available to do this change automatically in the zope.fixers package. - Python 2.3 is no longer supported. 3.5.4 (2009-12-23) ------------------ - Use the standard Python doctest module instead of zope.testing.doctest, which has been deprecated. 3.5.3 (2009-12-08) ------------------ - Fix an edge case: make providedBy() work when a class has '__provides__' in its __slots__ (see http://thread.gmane.org/gmane.comp.web.zope.devel/22490) 3.5.2 (2009-07-01) ------------------ - BaseAdapterRegistry.unregister, unsubscribe: Remove empty portions of the data structures when something is removed. This avoids leaving references to global objects (interfaces) that may be slated for removal from the calling application. 3.5.1 (2009-03-18) ------------------ - verifyObject: use getattr instead of hasattr to test for object attributes in order to let exceptions other than AttributeError raised by properties propagate to the caller - Add Sphinx-based documentation building to the package buildout configuration. Use the ``bin/docs`` command after buildout. - Improve package description a bit. Unify changelog entries formatting. - Change package's mailing list address to zope-dev at zope.org as zope3-dev at zope.org is now retired. 3.5.0 (2008-10-26) ------------------ - Fixed declaration of _zope_interface_coptimizations, it's not a top level package. - Add a DocTestSuite for odd.py module, so their tests are run. - Allow to bootstrap on Jython. - Fix https://bugs.launchpad.net/zope3/3.3/+bug/98388: ISpecification was missing a declaration for __iro__. - Added optional code optimizations support, which allows the building of C code optimizations to fail (Jython). - Replaced `_flatten` with a non-recursive implementation, effectively making it 3x faster. 3.4.1 (2007-10-02) ------------------ - Fixed a setup bug that prevented installation from source on systems without setuptools. 3.4.0 (2007-07-19) ------------------ - Final release for 3.4.0. 3.4.0b3 (2007-05-22) -------------------- - Objects with picky custom comparison methods couldn't be added to component registries. Now, when checking whether an object is already registered, identity comparison is used. 3.3.0.1 (2007-01-03) -------------------- - Made a reference to OverflowWarning, which disappeared in Python 2.5, conditional. 3.3.0 (2007/01/03) ------------------ New Features ++++++++++++ - The adapter-lookup algorithim was refactored to make it much simpler and faster. Also, more of the adapter-lookup logic is implemented in C, making debugging of application code easier, since there is less infrastructre code to step through. - We now treat objects without interface declarations as if they declared that they provide zope.interface.Interface. - There are a number of richer new adapter-registration interfaces that provide greater control and introspection. - Added a new interface decorator to zope.interface that allows the setting of tagged values on an interface at definition time (see zope.interface.taggedValue). Bug Fixes +++++++++ - A bug in multi-adapter lookup sometimes caused incorrect adapters to be returned. 3.2.0.2 (2006-04-15) -------------------- - Fix packaging bug: 'package_dir' must be a *relative* path. 3.2.0.1 (2006-04-14) -------------------- - Packaging change: suppress inclusion of 'setup.cfg' in 'sdist' builds. 3.2.0 (2006-01-05) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope 3.2.0 release. 3.1.0 (2005-10-03) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope 3.1.0 release. - Made attribute resolution order consistent with component lookup order, i.e. new-style class MRO semantics. - Deprecated 'isImplementedBy' and 'isImplementedByInstancesOf' APIs in favor of 'implementedBy' and 'providedBy'. 3.0.1 (2005-07-27) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope X3.0.1 release. - Fixed a bug reported by James Knight, which caused adapter registries to fail occasionally to reflect declaration changes. 3.0.0 (2004-11-07) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope X3.0.0 release. zope2.13-2.13.21/source/zope.interface/src/0000755000175000017500000000000012214017572017143 5ustar arnauarnauzope2.13-2.13.21/source/zope.interface/src/zope/0000755000175000017500000000000012214017572020120 5ustar arnauarnauzope2.13-2.13.21/source/zope.interface/src/zope/__init__.py0000644000175000017500000000031012214017572022223 0ustar arnauarnau# this is a namespace package try: import pkg_resources pkg_resources.declare_namespace(__name__) except ImportError: import pkgutil __path__ = pkgutil.extend_path(__path__, __name__) zope2.13-2.13.21/source/zope.interface/src/zope/interface/0000755000175000017500000000000012214017572022060 5ustar arnauarnauzope2.13-2.13.21/source/zope.interface/src/zope/interface/_flatten.py0000644000175000017500000000213012214017572024222 0ustar arnauarnau############################################################################## # # Copyright (c) 2002 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

In addition, the registrations have names. (You can think of the names as qualifiers of the provided interfaces.) The term "interface specification" refers both to interfaces and to interface declarations, such as declarations of interfaces implemented by a class. Single Adapters =============== Let's look at a simple example, using a single required specification:: >>> from zope.interface.adapter import AdapterRegistry >>> import zope.interface >>> class IR1(zope.interface.Interface): ... pass >>> class IP1(zope.interface.Interface): ... pass >>> class IP2(IP1): ... pass >>> registry = AdapterRegistry() We'll register an object that depends on IR1 and "provides" IP2:: >>> registry.register([IR1], IP2, '', 12) Given the registration, we can look it up again:: >>> registry.lookup([IR1], IP2, '') 12 Note that we used an integer in the example. In real applications, one would use some objects that actually depend on or provide interfaces. The registry doesn't care about what gets registered, so we'll use integers and strings to keep the examples simple. There is one exception. Registering a value of None unregisters any previously-registered value. If an object depends on a specification, it can be looked up with a specification that extends the specification that it depends on:: >>> class IR2(IR1): ... pass >>> registry.lookup([IR2], IP2, '') 12 We can use a class implementation specification to look up the object:: >>> class C2: ... zope.interface.implements(IR2) >>> registry.lookup([zope.interface.implementedBy(C2)], IP2, '') 12 and it can be looked up for interfaces that its provided interface extends:: >>> registry.lookup([IR1], IP1, '') 12 >>> registry.lookup([IR2], IP1, '') 12 But if you require a specification that doesn't extend the specification the object depends on, you won't get anything:: >>> registry.lookup([zope.interface.Interface], IP1, '') By the way, you can pass a default value to lookup:: >>> registry.lookup([zope.interface.Interface], IP1, '', 42) 42 If you try to get an interface the object doesn't provide, you also won't get anything:: >>> class IP3(IP2): ... pass >>> registry.lookup([IR1], IP3, '') You also won't get anything if you use the wrong name:: >>> registry.lookup([IR1], IP1, 'bob') >>> registry.register([IR1], IP2, 'bob', "Bob's 12") >>> registry.lookup([IR1], IP1, 'bob') "Bob's 12" You can leave the name off when doing a lookup:: >>> registry.lookup([IR1], IP1) 12 If we register an object that provides IP1:: >>> registry.register([IR1], IP1, '', 11) then that object will be prefered over O(12):: >>> registry.lookup([IR1], IP1, '') 11 Also, if we register an object for IR2, then that will be prefered when using IR2:: >>> registry.register([IR2], IP1, '', 21) >>> registry.lookup([IR2], IP1, '') 21 Finding out what, if anything, is registered -------------------------------------------- We can ask if there is an adapter registered for a collection of interfaces. This is different than lookup, because it looks for an exact match. >>> print registry.registered([IR1], IP1) 11 >>> print registry.registered([IR1], IP2) 12 >>> print registry.registered([IR1], IP2, 'bob') Bob's 12 >>> print registry.registered([IR2], IP1) 21 >>> print registry.registered([IR2], IP2) None In the last example, None was returned because nothing was registered exactly for the given interfaces. lookup1 ------- Lookup of single adapters is common enough that there is a specialized version of lookup that takes a single required interface:: >>> registry.lookup1(IR2, IP1, '') 21 >>> registry.lookup1(IR2, IP1) 21 Actual Adaptation ----------------- The adapter registry is intended to support adaptation, where one object that implements an interface is adapted to another object that supports a different interface. The adapter registry supports the computation of adapters. In this case, we have to register adapter factories:: >>> class IR(zope.interface.Interface): ... pass >>> class X: ... zope.interface.implements(IR) >>> class Y: ... zope.interface.implements(IP1) ... def __init__(self, context): ... self.context = context >>> registry.register([IR], IP1, '', Y) In this case, we registered a class as the factory. Now we can call `queryAdapter` to get the adapted object:: >>> x = X() >>> y = registry.queryAdapter(x, IP1) >>> y.__class__.__name__ 'Y' >>> y.context is x True We can register and lookup by name too:: >>> class Y2(Y): ... pass >>> registry.register([IR], IP1, 'bob', Y2) >>> y = registry.queryAdapter(x, IP1, 'bob') >>> y.__class__.__name__ 'Y2' >>> y.context is x True When the adapter factory produces `None`, then this is treated as if no adapter has been found. This allows us to prevent adaptation (when desired) and let the adapter factory determine whether adaptation is possible based on the state of the object being adapted. >>> def factory(context): ... if context.name == 'object': ... return 'adapter' ... return None >>> class Object(object): ... zope.interface.implements(IR) ... name = 'object' >>> registry.register([IR], IP1, 'conditional', factory) >>> obj = Object() >>> registry.queryAdapter(obj, IP1, 'conditional') 'adapter' >>> obj.name = 'no object' >>> registry.queryAdapter(obj, IP1, 'conditional') is None True >>> registry.queryAdapter(obj, IP1, 'conditional', 'default') 'default' An alternate method that provides the same function as `queryAdapter()` is `adapter_hook()`:: >>> y = registry.adapter_hook(IP1, x) >>> y.__class__.__name__ 'Y' >>> y.context is x True >>> y = registry.adapter_hook(IP1, x, 'bob') >>> y.__class__.__name__ 'Y2' >>> y.context is x True The `adapter_hook()` simply switches the order of the object and interface arguments. It is used to hook into the interface call mechanism. Default Adapters ---------------- Sometimes, you want to provide an adapter that will adapt anything. For that, provide None as the required interface:: >>> registry.register([None], IP1, '', 1) then we can use that adapter for interfaces we don't have specific adapters for:: >>> class IQ(zope.interface.Interface): ... pass >>> registry.lookup([IQ], IP1, '') 1 Of course, specific adapters are still used when applicable:: >>> registry.lookup([IR2], IP1, '') 21 Class adapters -------------- You can register adapters for class declarations, which is almost the same as registering them for a class:: >>> registry.register([zope.interface.implementedBy(C2)], IP1, '', 'C21') >>> registry.lookup([zope.interface.implementedBy(C2)], IP1, '') 'C21' Dict adapters ------------- At some point it was impossible to register dictionary-based adapters due a bug. Let's make sure this works now: >>> adapter = {} >>> registry.register((), IQ, '', adapter) >>> registry.lookup((), IQ, '') is adapter True Unregistering ------------- You can unregister by registering None, rather than an object:: >>> registry.register([zope.interface.implementedBy(C2)], IP1, '', None) >>> registry.lookup([zope.interface.implementedBy(C2)], IP1, '') 21 Of course, this means that None can't be registered. This is an exception to the statement, made earlier, that the registry doesn't care what gets registered. Multi-adapters ============== You can adapt multiple specifications:: >>> registry.register([IR1, IQ], IP2, '', '1q2') >>> registry.lookup([IR1, IQ], IP2, '') '1q2' >>> registry.lookup([IR2, IQ], IP1, '') '1q2' >>> class IS(zope.interface.Interface): ... pass >>> registry.lookup([IR2, IS], IP1, '') >>> class IQ2(IQ): ... pass >>> registry.lookup([IR2, IQ2], IP1, '') '1q2' >>> registry.register([IR1, IQ2], IP2, '', '1q22') >>> registry.lookup([IR2, IQ2], IP1, '') '1q22' Multi-adaptation ---------------- You can adapt multiple objects:: >>> class Q: ... zope.interface.implements(IQ) As with single adapters, we register a factory, which is often a class:: >>> class IM(zope.interface.Interface): ... pass >>> class M: ... zope.interface.implements(IM) ... def __init__(self, x, q): ... self.x, self.q = x, q >>> registry.register([IR, IQ], IM, '', M) And then we can call `queryMultiAdapter` to compute an adapter:: >>> q = Q() >>> m = registry.queryMultiAdapter((x, q), IM) >>> m.__class__.__name__ 'M' >>> m.x is x and m.q is q True and, of course, we can use names:: >>> class M2(M): ... pass >>> registry.register([IR, IQ], IM, 'bob', M2) >>> m = registry.queryMultiAdapter((x, q), IM, 'bob') >>> m.__class__.__name__ 'M2' >>> m.x is x and m.q is q True Default Adapters ---------------- As with single adapters, you can define default adapters by specifying None for the *first* specification:: >>> registry.register([None, IQ], IP2, '', 'q2') >>> registry.lookup([IS, IQ], IP2, '') 'q2' Null Adapters ============= You can also adapt no specification:: >>> registry.register([], IP2, '', 2) >>> registry.lookup([], IP2, '') 2 >>> registry.lookup([], IP1, '') 2 Listing named adapters ---------------------- Adapters are named. Sometimes, it's useful to get all of the named adapters for given interfaces:: >>> adapters = list(registry.lookupAll([IR1], IP1)) >>> adapters.sort() >>> assert adapters == [(u'', 11), (u'bob', "Bob's 12")] This works for multi-adapters too:: >>> registry.register([IR1, IQ2], IP2, 'bob', '1q2 for bob') >>> adapters = list(registry.lookupAll([IR2, IQ2], IP1)) >>> adapters.sort() >>> assert adapters == [(u'', '1q22'), (u'bob', '1q2 for bob')] And even null adapters:: >>> registry.register([], IP2, 'bob', 3) >>> adapters = list(registry.lookupAll([], IP1)) >>> adapters.sort() >>> assert adapters == [(u'', 2), (u'bob', 3)] Subscriptions ============= Normally, we want to look up an object that most-closely matches a specification. Sometimes, we want to get all of the objects that match some specification. We use subscriptions for this. We subscribe objects against specifications and then later find all of the subscribed objects:: >>> registry.subscribe([IR1], IP2, 'sub12 1') >>> registry.subscriptions([IR1], IP2) ['sub12 1'] Note that, unlike regular adapters, subscriptions are unnamed. You can have multiple subscribers for the same specification:: >>> registry.subscribe([IR1], IP2, 'sub12 2') >>> registry.subscriptions([IR1], IP2) ['sub12 1', 'sub12 2'] If subscribers are registered for the same required interfaces, they are returned in the order of definition. You can register subscribers for all specifications using None:: >>> registry.subscribe([None], IP1, 'sub_1') >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2'] Note that the new subscriber is returned first. Subscribers defined for less general required interfaces are returned before subscribers for more general interfaces. Subscriptions may be combined over multiple compatible specifications:: >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2'] >>> registry.subscribe([IR1], IP1, 'sub11') >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2', 'sub11'] >>> registry.subscribe([IR2], IP2, 'sub22') >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2', 'sub11', 'sub22'] >>> registry.subscriptions([IR2], IP2) ['sub12 1', 'sub12 2', 'sub22'] Subscriptions can be on multiple specifications:: >>> registry.subscribe([IR1, IQ], IP2, 'sub1q2') >>> registry.subscriptions([IR1, IQ], IP2) ['sub1q2'] As with single subscriptions and non-subscription adapters, you can specify None for the first required interface, to specify a default:: >>> registry.subscribe([None, IQ], IP2, 'sub_q2') >>> registry.subscriptions([IS, IQ], IP2) ['sub_q2'] >>> registry.subscriptions([IR1, IQ], IP2) ['sub_q2', 'sub1q2'] You can have subscriptions that are indepenent of any specifications:: >>> list(registry.subscriptions([], IP1)) [] >>> registry.subscribe([], IP2, 'sub2') >>> registry.subscriptions([], IP1) ['sub2'] >>> registry.subscribe([], IP1, 'sub1') >>> registry.subscriptions([], IP1) ['sub2', 'sub1'] >>> registry.subscriptions([], IP2) ['sub2'] Unregistering subscribers ------------------------- We can unregister subscribers. When unregistering a subscriber, we can unregister a specific subscriber:: >>> registry.unsubscribe([IR1], IP1, 'sub11') >>> registry.subscriptions([IR1], IP1) ['sub_1', 'sub12 1', 'sub12 2'] If we don't specify a value, then all subscribers matching the given interfaces will be unsubscribed: >>> registry.unsubscribe([IR1], IP2) >>> registry.subscriptions([IR1], IP1) ['sub_1'] Subscription adapters --------------------- We normally register adapter factories, which then allow us to compute adapters, but with subscriptions, we get multiple adapters. Here's an example of multiple-object subscribers:: >>> registry.subscribe([IR, IQ], IM, M) >>> registry.subscribe([IR, IQ], IM, M2) >>> subscribers = registry.subscribers((x, q), IM) >>> len(subscribers) 2 >>> class_names = [s.__class__.__name__ for s in subscribers] >>> class_names.sort() >>> class_names ['M', 'M2'] >>> [(s.x is x and s.q is q) for s in subscribers] [True, True] adapter factory subcribers can't return None values:: >>> def M3(x, y): ... return None >>> registry.subscribe([IR, IQ], IM, M3) >>> subscribers = registry.subscribers((x, q), IM) >>> len(subscribers) 2 Handlers -------- A handler is a subscriber factory that doesn't produce any normal output. It returns None. A handler is unlike adapters in that it does all of its work when the factory is called. To register a handler, simply provide None as the provided interface:: >>> def handler(event): ... print 'handler', event >>> registry.subscribe([IR1], None, handler) >>> registry.subscriptions([IR1], None) == [handler] True zope2.13-2.13.21/source/zope.interface/src/zope/interface/human.txt0000644000175000017500000001417212214017572023736 0ustar arnauarnau========================== Using the Adapter Registry ========================== This is a small demonstration of the ``zope.interface`` package including its adapter registry. It is intended to provide a concrete but narrow example on how to use interfaces and adapters outside of Zope 3. First we have to import the interface package:: >>> import zope.interface We now develop an interface for our object, which is a simple file in this case. For now we simply support one attribute, the body, which contains the actual file contents:: >>> class IFile(zope.interface.Interface): ... ... body = zope.interface.Attribute('Contents of the file.') ... For statistical reasons we often want to know the size of a file. However, it would be clumsy to implement the size directly in the file object, since the size really represents meta-data. Thus we create another interface that provides the size of something:: >>> class ISize(zope.interface.Interface): ... ... def getSize(): ... 'Return the size of an object.' ... Now we need to implement the file. It is essential that the object states that it implements the `IFile` interface. We also provide a default body value (just to make things simpler for this example):: >>> class File(object): ... ... zope.interface.implements(IFile) ... body = 'foo bar' ... Next we implement an adapter that can provide the `ISize` interface given any object providing `IFile`. By convention we use `__used_for__` to specify the interface that we expect the adapted object to provide, in our case `IFile`. However, this attribute is not used for anything. If you have multiple interfaces for which an adapter is used, just specify the interfaces via a tuple. Again by convention, the constructor of an adapter takes one argument, the context. The context in this case is an instance of `File` (providing `IFile`) that is used to extract the size from. Also by convention the context is stored in an attribute named `context` on the adapter. The twisted community refers to the context as the `original` object. However, you may feel free to use a specific argument name, such as `file`:: >>> class FileSize(object): ... ... zope.interface.implements(ISize) ... __used_for__ = IFile ... ... def __init__(self, context): ... self.context = context ... ... def getSize(self): ... return len(self.context.body) ... Now that we have written our adapter, we have to register it with an adapter registry, so that it can be looked up when needed. There is no such thing as a global registry; thus we have to instantiate one for our example manually:: >>> from zope.interface.adapter import AdapterRegistry >>> registry = AdapterRegistry() The registry keeps a map of what adapters implement based on another interface, the object already provides. Therefore, we next have to register an adapter that adapts from `IFile` to `ISize`. The first argument to the registry's `register()` method is a list of original interfaces.In our cause we have only one original interface, `IFile`. A list makes sense, since the interface package has the concept of multi-adapters, which are adapters that require multiple objects to adapt to a new interface. In these situations, your adapter constructor will require an argument for each specified interface. The second argument is the interface the adapter provides, in our case `ISize`. The third argument is the name of the adapter. Since we do not care about names, we simply leave it as an empty string. Names are commonly useful, if you have adapters for the same set of interfaces, but they are useful in different situations. The last argument is simply the adapter class:: >>> registry.register([IFile], ISize, '', FileSize) You can now use the the registry to lookup the adapter:: >>> registry.lookup1(IFile, ISize, '') Let's get a little bit more practical. Let's create a `File` instance and create the adapter using a registry lookup. Then we see whether the adapter returns the correct size by calling `getSize()`:: >>> file = File() >>> size = registry.lookup1(IFile, ISize, '')(file) >>> size.getSize() 7 However, this is not very practical, since I have to manually pass in the arguments to the lookup method. There is some syntactic candy that will allow us to get an adapter instance by simply calling `ISize(file)`. To make use of this functionality, we need to add our registry to the adapter_hooks list, which is a member of the adapters module. This list stores a collection of callables that are automatically invoked when IFoo(obj) is called; their purpose is to locate adapters that implement an interface for a certain context instance. You are required to implement your own adapter hook; this example covers one of the simplest hooks that use the registry, but you could implement one that used an adapter cache or persistent adapters, for instance. The helper hook is required to expect as first argument the desired output interface (for us `ISize`) and as the second argument the context of the adapter (here `file`). The function returns an adapter, i.e. a `FileSize` instance:: >>> def hook(provided, object): ... adapter = registry.lookup1(zope.interface.providedBy(object), ... provided, '') ... return adapter(object) ... We now just add the hook to an `adapter_hooks` list:: >>> from zope.interface.interface import adapter_hooks >>> adapter_hooks.append(hook) Once the hook is registered, you can use the desired syntax:: >>> size = ISize(file) >>> size.getSize() 7 Now we have to cleanup after ourselves, so that others after us have a clean `adapter_hooks` list:: >>> adapter_hooks.remove(hook) That's it. I have intentionally left out a discussion of named adapters and multi-adapters, since this text is intended as a practical and simple introduction to Zope 3 interfaces and adapters. You might want to read the `adapter.txt` in the `zope.interface` package for a more formal, referencial and complete treatment of the package.

Attribute descriptions include the name of the attribute and prose documentation describing the attributes usage. o Descriptions of methods.

Examples uses for this are examples, security assertions, pre/post conditions, and other possible information you may want to associate with an Interface or its attributes. Not all of this information is mandatory. For example, you may only want the methods of your interface to have prose documentation and not describe the arguments of the method in exact detail. Interface objects are flexible and let you give or take any of these components.

There are several ways that you can assert that an object implements an interface: 1. Call zope.interface.implements in your class definition. 2. Call zope.interfaces.directlyProvides on your object. 3. Call 'zope.interface.classImplements' to assert that instances of a class implement an interface. For example:: from zope.interface import classImplements classImplements(some_class, some_interface) This approach is useful when it is not an option to modify the class source.

The package exports two objects, `Interface` and `Attribute` directly. It also exports several helper methods. Interface is used to create an interface with a class statement, as in: class IMyInterface(Interface): '''Interface documentation ''' def meth(arg1, arg2): '''Documentation for meth ''' # Note that there is no self argument To find out what you can do with interfaces, see the interface interface, `IInterface` in the `interfaces` module. The package has several public modules: o `declarations` provides utilities to declare interfaces on objects. It also provides a wide range of helpful utilities that aid in managing declared interfaces. Most of its public names are however imported here. o `document` has a utility for documenting an interface as structured text. o `exceptions` has the interface-defined exceptions o `interfaces` contains a list of all public interfaces for this package. o `verify` has utilities for verifying implementations of interfaces.

An interface specifies behavior through: - Informal documentation in a doc string - Attribute definitions - Invariants, which are conditions that must hold for objects that provide the interface Attribute definitions specify specific attributes. They define the attribute name and provide documentation and constraints of attribute values. Attribute definitions can take a number of forms, as we'll see below. Defining interfaces =================== Interfaces are defined using Python class statements:: >>> import zope.interface >>> class IFoo(zope.interface.Interface): ... """Foo blah blah""" ... ... x = zope.interface.Attribute("""X blah blah""") ... ... def bar(q, r=None): ... """bar blah blah""" In the example above, we've created an interface, `IFoo`. We subclassed `zope.interface.Interface`, which is an ancestor interface for all interfaces, much as `object` is an ancestor of all new-style classes [#create]_. The interface is not a class, it's an Interface, an instance of `InterfaceClass`:: >>> type(IFoo) We can ask for the interface's documentation:: >>> IFoo.__doc__ 'Foo blah blah' and its name:: >>> IFoo.__name__ 'IFoo' and even its module:: >>> IFoo.__module__ '__main__' The interface defined two attributes: `x` This is the simplest form of attribute definition. It has a name and a doc string. It doesn't formally specify anything else. `bar` This is a method. A method is defined via a function definition. A method is simply an attribute constrained to be a callable with a particular signature, as provided by the function definition. Note that `bar` doesn't take a `self` argument. Interfaces document how an object is *used*. When calling instance methods, you don't pass a `self` argument, so a `self` argument isn't included in the interface signature. The `self` argument in instance methods is really an implementation detail of Python instances. Other objects, besides instances can provide interfaces and their methods might not be instance methods. For example, modules can provide interfaces and their methods are usually just functions. Even instances can have methods that are not instance methods. You can access the attributes defined by an interface using mapping syntax:: >>> x = IFoo['x'] >>> type(x) >>> x.__name__ 'x' >>> x.__doc__ 'X blah blah' >>> IFoo.get('x').__name__ 'x' >>> IFoo.get('y') You can use `in` to determine if an interface defines a name:: >>> 'x' in IFoo True You can iterate over interfaces to get the names they define:: >>> names = list(IFoo) >>> names.sort() >>> names ['bar', 'x'] Remember that interfaces aren't classes. You can't access attribute definitions as attributes of interfaces:: >>> IFoo.x Traceback (most recent call last): File "", line 1, in ? AttributeError: 'InterfaceClass' object has no attribute 'x' Methods provide access to the method signature:: >>> bar = IFoo['bar'] >>> bar.getSignatureString() '(q, r=None)' TODO Methods really should have a better API. This is something that needs to be improved. Declaring interfaces ==================== Having defined interfaces, we can *declare* that objects provide them. Before we describe the details, lets define some terms: *provide* We say that objects *provide* interfaces. If an object provides an interface, then the interface specifies the behavior of the object. In other words, interfaces specify the behavior of the objects that provide them. *implement* We normally say that classes *implement* interfaces. If a class implements an interface, then the instances of the class provide the interface. Objects provide interfaces that their classes implement [#factory]_. (Objects can provide interfaces directly, in addition to what their classes implement.) It is important to note that classes don't usually provide the interfaces that they implement. We can generalize this to factories. For any callable object we can declare that it produces objects that provide some interfaces by saying that the factory implements the interfaces. Now that we've defined these terms, we can talk about the API for declaring interfaces. Declaring implemented interfaces -------------------------------- The most common way to declare interfaces is using the implements function in a class statement:: >>> class Foo: ... zope.interface.implements(IFoo) ... ... def __init__(self, x=None): ... self.x = x ... ... def bar(self, q, r=None): ... return q, r, self.x ... ... def __repr__(self): ... return "Foo(%s)" % self.x In this example, we declared that `Foo` implements `IFoo`. This means that instances of `Foo` provide `IFoo`. Having made this declaration, there are several ways we can introspect the declarations. First, we can ask an interface whether it is implemented by a class:: >>> IFoo.implementedBy(Foo) True And we can ask whether an interface is provided by an object:: >>> foo = Foo() >>> IFoo.providedBy(foo) True Of course, `Foo` doesn't provide `IFoo`, it implements it:: >>> IFoo.providedBy(Foo) False We can also ask what interfaces are implemented by an object:: >>> list(zope.interface.implementedBy(Foo)) [] It's an error to ask for interfaces implemented by a non-callable object:: >>> IFoo.implementedBy(foo) Traceback (most recent call last): ... TypeError: ('ImplementedBy called for non-factory', Foo(None)) >>> list(zope.interface.implementedBy(foo)) Traceback (most recent call last): ... TypeError: ('ImplementedBy called for non-factory', Foo(None)) Similarly, we can ask what interfaces are provided by an object:: >>> list(zope.interface.providedBy(foo)) [] >>> list(zope.interface.providedBy(Foo)) [] We can declare interfaces implemented by other factories (besides classes). We do this using a Python-2.4-style decorator named `implementer`. In versions of Python before 2.4, this looks like:: >>> def yfoo(y): ... foo = Foo() ... foo.y = y ... return foo >>> yfoo = zope.interface.implementer(IFoo)(yfoo) >>> list(zope.interface.implementedBy(yfoo)) [] Note that the implementer decorator may modify it's argument. Callers should not assume that a new object is created. Using implementer also works on callable objects. This is used by zope.formlib, as an example. >>> class yfactory: ... def __call__(self, y): ... foo = Foo() ... foo.y = y ... return foo >>> yfoo = yfactory() >>> yfoo = zope.interface.implementer(IFoo)(yfoo) >>> list(zope.interface.implementedBy(yfoo)) [] XXX: Double check and update these version numbers: In zope.interface 3.5.2 and lower, the implementor decorator can not be used for classes, but in 3.6.0 and higher it can: >>> Foo = zope.interface.implementer(IFoo)(Foo) >>> list(zope.interface.providedBy(Foo())) [] Note that class decorators using the @implementor(IFoo) syntax are only supported in Python 2.6 and later. Declaring provided interfaces ----------------------------- We can declare interfaces directly provided by objects. Suppose that we want to document what the `__init__` method of the `Foo` class does. It's not *really* part of `IFoo`. You wouldn't normally call the `__init__` method on Foo instances. Rather, the `__init__` method is part of the `Foo`'s `__call__` method:: >>> class IFooFactory(zope.interface.Interface): ... """Create foos""" ... ... def __call__(x=None): ... """Create a foo ... ... The argument provides the initial value for x ... ... """ It's the class that provides this interface, so we declare the interface on the class:: >>> zope.interface.directlyProvides(Foo, IFooFactory) And then, we'll see that Foo provides some interfaces:: >>> list(zope.interface.providedBy(Foo)) [] >>> IFooFactory.providedBy(Foo) True Declaring class interfaces is common enough that there's a special declaration function for it, `classProvides`, that allows the declaration from within a class statement:: >>> class Foo2: ... zope.interface.implements(IFoo) ... zope.interface.classProvides(IFooFactory) ... ... def __init__(self, x=None): ... self.x = x ... ... def bar(self, q, r=None): ... return q, r, self.x ... ... def __repr__(self): ... return "Foo(%s)" % self.x >>> list(zope.interface.providedBy(Foo2)) [] >>> IFooFactory.providedBy(Foo2) True There's a similar function, `moduleProvides`, that supports interface declarations from within module definitions. For example, see the use of `moduleProvides` call in `zope.interface.__init__`, which declares that the package `zope.interface` provides `IInterfaceDeclaration`. Sometimes, we want to declare interfaces on instances, even though those instances get interfaces from their classes. Suppose we create a new interface, `ISpecial`:: >>> class ISpecial(zope.interface.Interface): ... reason = zope.interface.Attribute("Reason why we're special") ... def brag(): ... "Brag about being special" We can make an existing foo instance special by providing `reason` and `brag` attributes:: >>> foo.reason = 'I just am' >>> def brag(): ... return "I'm special!" >>> foo.brag = brag >>> foo.reason 'I just am' >>> foo.brag() "I'm special!" and by declaring the interface:: >>> zope.interface.directlyProvides(foo, ISpecial) then the new interface is included in the provided interfaces:: >>> ISpecial.providedBy(foo) True >>> list(zope.interface.providedBy(foo)) [, ] We can find out what interfaces are directly provided by an object:: >>> list(zope.interface.directlyProvidedBy(foo)) [] >>> newfoo = Foo() >>> list(zope.interface.directlyProvidedBy(newfoo)) [] Inherited declarations ---------------------- Normally, declarations are inherited:: >>> class SpecialFoo(Foo): ... zope.interface.implements(ISpecial) ... reason = 'I just am' ... def brag(self): ... return "I'm special because %s" % self.reason >>> list(zope.interface.implementedBy(SpecialFoo)) [, ] >>> list(zope.interface.providedBy(SpecialFoo())) [, ] Sometimes, you don't want to inherit declarations. In that case, you can use `implementsOnly`, instead of `implements`:: >>> class Special(Foo): ... zope.interface.implementsOnly(ISpecial) ... reason = 'I just am' ... def brag(self): ... return "I'm special because %s" % self.reason >>> list(zope.interface.implementedBy(Special)) [] >>> list(zope.interface.providedBy(Special())) [] External declarations --------------------- Normally, we make implementation declarations as part of a class definition. Sometimes, we may want to make declarations from outside the class definition. For example, we might want to declare interfaces for classes that we didn't write. The function `classImplements` can be used for this purpose:: >>> class C: ... pass >>> zope.interface.classImplements(C, IFoo) >>> list(zope.interface.implementedBy(C)) [] We can use `classImplementsOnly` to exclude inherited interfaces:: >>> class C(Foo): ... pass >>> zope.interface.classImplementsOnly(C, ISpecial) >>> list(zope.interface.implementedBy(C)) [] Declaration Objects ------------------- When we declare interfaces, we create *declaration* objects. When we query declarations, declaration objects are returned:: >>> type(zope.interface.implementedBy(Special)) Declaration objects and interface objects are similar in many ways. In fact, they share a common base class. The important thing to realize about them is that they can be used where interfaces are expected in declarations. Here's a silly example:: >>> class Special2(Foo): ... zope.interface.implementsOnly( ... zope.interface.implementedBy(Foo), ... ISpecial, ... ) ... reason = 'I just am' ... def brag(self): ... return "I'm special because %s" % self.reason The declaration here is almost the same as ``zope.interface.implements(ISpecial)``, except that the order of interfaces in the resulting declaration is different:: >>> list(zope.interface.implementedBy(Special2)) [, ] Interface Inheritance ===================== Interfaces can extend other interfaces. They do this simply by listing the other interfaces as base interfaces:: >>> class IBlat(zope.interface.Interface): ... """Blat blah blah""" ... ... y = zope.interface.Attribute("y blah blah") ... def eek(): ... """eek blah blah""" >>> IBlat.__bases__ (,) >>> class IBaz(IFoo, IBlat): ... """Baz blah""" ... def eek(a=1): ... """eek in baz blah""" ... >>> IBaz.__bases__ (, ) >>> names = list(IBaz) >>> names.sort() >>> names ['bar', 'eek', 'x', 'y'] Note that `IBaz` overrides eek:: >>> IBlat['eek'].__doc__ 'eek blah blah' >>> IBaz['eek'].__doc__ 'eek in baz blah' We were careful to override eek in a compatible way. When extending an interface, the extending interface should be compatible [#compat]_ with the extended interfaces. We can ask whether one interface extends another:: >>> IBaz.extends(IFoo) True >>> IBlat.extends(IFoo) False Note that interfaces don't extend themselves:: >>> IBaz.extends(IBaz) False Sometimes we wish they did, but we can, instead use `isOrExtends`:: >>> IBaz.isOrExtends(IBaz) True >>> IBaz.isOrExtends(IFoo) True >>> IFoo.isOrExtends(IBaz) False When we iterate over an interface, we get all of the names it defines, including names defined by base interfaces. Sometimes, we want *just* the names defined by the interface directly. We bane use the `names` method for that:: >>> list(IBaz.names()) ['eek'] Inheritance of attribute specifications --------------------------------------- An interface may override attribute definitions from base interfaces. If two base interfaces define the same attribute, the attribute is inherited from the most specific interface. For example, with:: >>> class IBase(zope.interface.Interface): ... ... def foo(): ... "base foo doc" >>> class IBase1(IBase): ... pass >>> class IBase2(IBase): ... ... def foo(): ... "base2 foo doc" >>> class ISub(IBase1, IBase2): ... pass ISub's definition of foo is the one from IBase2, since IBase2 is more specific that IBase:: >>> ISub['foo'].__doc__ 'base2 foo doc' Note that this differs from a depth-first search. Sometimes, it's useful to ask whether an interface defines an attribute directly. You can use the direct method to get a directly defined definitions:: >>> IBase.direct('foo').__doc__ 'base foo doc' >>> ISub.direct('foo') Specifications -------------- Interfaces and declarations are both special cases of specifications. What we described above for interface inheritance applies to both declarations and specifications. Declarations actually extend the interfaces that they declare:: >>> class Baz(object): ... zope.interface.implements(IBaz) >>> baz_implements = zope.interface.implementedBy(Baz) >>> baz_implements.__bases__ (, ) >>> baz_implements.extends(IFoo) True >>> baz_implements.isOrExtends(IFoo) True >>> baz_implements.isOrExtends(baz_implements) True Specifications (interfaces and declarations) provide an `__sro__` that lists the specification and all of it's ancestors:: >>> baz_implements.__sro__ (, , , , , ) Tagged Values ============= Interfaces and attribute descriptions support an extension mechanism, borrowed from UML, called "tagged values" that lets us store extra data:: >>> IFoo.setTaggedValue('date-modified', '2004-04-01') >>> IFoo.setTaggedValue('author', 'Jim Fulton') >>> IFoo.getTaggedValue('date-modified') '2004-04-01' >>> IFoo.queryTaggedValue('date-modified') '2004-04-01' >>> IFoo.queryTaggedValue('datemodified') >>> tags = list(IFoo.getTaggedValueTags()) >>> tags.sort() >>> tags ['author', 'date-modified'] Function attributes are converted to tagged values when method attribute definitions are created:: >>> class IBazFactory(zope.interface.Interface): ... def __call__(): ... "create one" ... __call__.return_type = IBaz >>> IBazFactory['__call__'].getTaggedValue('return_type') Tagged values can also be defined from within an interface definition:: >>> class IWithTaggedValues(zope.interface.Interface): ... zope.interface.taggedValue('squish', 'squash') >>> IWithTaggedValues.getTaggedValue('squish') 'squash' Invariants ========== Interfaces can express conditions that must hold for objects that provide them. These conditions are expressed using one or more invariants. Invariants are callable objects that will be called with an object that provides an interface. An invariant raises an `Invalid` exception if the condition doesn't hold. Here's an example:: >>> class RangeError(zope.interface.Invalid): ... """A range has invalid limits""" ... def __repr__(self): ... return "RangeError(%r)" % self.args >>> def range_invariant(ob): ... if ob.max < ob.min: ... raise RangeError(ob) Given this invariant, we can use it in an interface definition:: >>> class IRange(zope.interface.Interface): ... min = zope.interface.Attribute("Lower bound") ... max = zope.interface.Attribute("Upper bound") ... ... zope.interface.invariant(range_invariant) Interfaces have a method for checking their invariants:: >>> class Range(object): ... zope.interface.implements(IRange) ... ... def __init__(self, min, max): ... self.min, self.max = min, max ... ... def __repr__(self): ... return "Range(%s, %s)" % (self.min, self.max) >>> IRange.validateInvariants(Range(1,2)) >>> IRange.validateInvariants(Range(1,1)) >>> IRange.validateInvariants(Range(2,1)) Traceback (most recent call last): ... RangeError: Range(2, 1) If you have multiple invariants, you may not want to stop checking after the first error. If you pass a list to `validateInvariants`, then a single `Invalid` exception will be raised with the list of exceptions as it's argument:: >>> from zope.interface.exceptions import Invalid >>> errors = [] >>> try: ... IRange.validateInvariants(Range(2,1), errors) ... except Invalid, e: ... str(e) '[RangeError(Range(2, 1))]' And the list will be filled with the individual exceptions:: >>> errors [RangeError(Range(2, 1))] >>> del errors[:] Adaptation ========== Interfaces can be called to perform adaptation. The semantics are based on those of the PEP 246 adapt function. If an object cannot be adapted, then a TypeError is raised:: >>> class I(zope.interface.Interface): ... pass >>> I(0) Traceback (most recent call last): ... TypeError: ('Could not adapt', 0, ) unless an alternate value is provided as a second positional argument:: >>> I(0, 'bob') 'bob' If an object already implements the interface, then it will be returned:: >>> class C(object): ... zope.interface.implements(I) >>> obj = C() >>> I(obj) is obj True If an object implements __conform__, then it will be used:: >>> class C(object): ... zope.interface.implements(I) ... def __conform__(self, proto): ... return 0 >>> I(C()) 0 Adapter hooks (see __adapt__) will also be used, if present:: >>> from zope.interface.interface import adapter_hooks >>> def adapt_0_to_42(iface, obj): ... if obj == 0: ... return 42 >>> adapter_hooks.append(adapt_0_to_42) >>> I(0) 42 >>> adapter_hooks.remove(adapt_0_to_42) >>> I(0) Traceback (most recent call last): ... TypeError: ('Could not adapt', 0, ) __adapt__ --------- >>> class I(zope.interface.Interface): ... pass Interfaces implement the PEP 246 __adapt__ method. This method is normally not called directly. It is called by the PEP 246 adapt framework and by the interface __call__ operator. The adapt method is responsible for adapting an object to the reciever. The default version returns None:: >>> I.__adapt__(0) unless the object given provides the interface:: >>> class C(object): ... zope.interface.implements(I) >>> obj = C() >>> I.__adapt__(obj) is obj True Adapter hooks can be provided (or removed) to provide custom adaptation. We'll install a silly hook that adapts 0 to 42. We install a hook by simply adding it to the adapter_hooks list:: >>> from zope.interface.interface import adapter_hooks >>> def adapt_0_to_42(iface, obj): ... if obj == 0: ... return 42 >>> adapter_hooks.append(adapt_0_to_42) >>> I.__adapt__(0) 42 Hooks must either return an adapter, or None if no adapter can be found. Hooks can be uninstalled by removing them from the list:: >>> adapter_hooks.remove(adapt_0_to_42) >>> I.__adapt__(0) .. [#create] The main reason we subclass `Interface` is to cause the Python class statement to create an interface, rather than a class. It's possible to create interfaces by calling a special interface class directly. Doing this, it's possible (and, on rare occasions, useful) to create interfaces that don't descend from `Interface`. Using this technique is beyond the scope of this document. .. [#factory] Classes are factories. They can be called to create their instances. We expect that we will eventually extend the concept of implementation to other kinds of factories, so that we can declare the interfaces provided by the objects created. .. [#compat] The goal is substitutability. An object that provides an extending interface should be substitutable for an object that provides the extended interface. In our example, an object that provides IBaz should be usable whereever an object that provides IBlat is expected. The interface implementation doesn't enforce this. but maybe it should do some checks. zope2.13-2.13.21/source/zope.interface/src/zope/interface/document.py0000644000175000017500000000672012214017572024255 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

Verifying classes ================= This is covered by unit tests defined in ``zope.interface.tests.test_verify``. Verifying objects ================= An object provides an interface if - either its class declares that it implements the interfaces, or the object declares that it directly provides the interface - the object defines all the methods required by the interface - all the methods have the correct signature - the object defines all non-method attributes required by the interface This doctest currently covers only the latter item. Testing for attributes ---------------------- Attributes of the object, be they defined by its class or added by its ``__init__`` method, will be recognized: >>> from zope.interface import Interface, Attribute, implements >>> from zope.interface.exceptions import BrokenImplementation >>> class IFoo(Interface): ... x = Attribute("The X attribute") ... y = Attribute("The Y attribute") >>> class Foo(object): ... implements(IFoo) ... x = 1 ... def __init__(self): ... self.y = 2 >>> from zope.interface.verify import verifyObject >>> verifyObject(IFoo, Foo()) True If either attribute is missing, verification will fail: >>> class Foo(object): ... implements(IFoo) ... x = 1 >>> try: #doctest: +NORMALIZE_WHITESPACE +ELLIPSIS ... verifyObject(IFoo, Foo()) ... except BrokenImplementation, e: ... print str(e) An object has failed to implement interface The y attribute was not provided. >>> class Foo(object): ... implements(IFoo) ... def __init__(self): ... self.y = 2 >>> try: #doctest: +NORMALIZE_WHITESPACE +ELLIPSIS ... verifyObject(IFoo, Foo()) ... except BrokenImplementation, e: ... print str(e) An object has failed to implement interface The x attribute was not provided. If an attribute is implemented as a property that raises an AttributeError when trying to get its value, the attribute is considered missing: >>> class IFoo(Interface): ... x = Attribute('The X attribute') >>> class Foo(object): ... implements(IFoo) ... @property ... def x(self): ... raise AttributeError >>> try: #doctest: +NORMALIZE_WHITESPACE +ELLIPSIS ... verifyObject(IFoo, Foo()) ... except BrokenImplementation, e: ... print str(e) An object has failed to implement interface The x attribute was not provided. Any other exception raised by a property will propagate to the caller of ``verifyObject``: >>> class Foo(object): ... implements(IFoo) ... @property ... def x(self): ... raise Exception >>> verifyObject(IFoo, Foo()) Traceback (most recent call last): Exception Of course, broken properties that are not required by the interface don't do any harm: >>> class Foo(object): ... implements(IFoo) ... x = 1 ... @property ... def y(self): ... raise Exception >>> verifyObject(IFoo, Foo()) True zope2.13-2.13.21/source/zope.interface/src/zope/interface/human.ru.txt0000644000175000017500000002467112214017572024370 0ustar arnauarnau=============================== ИÑпользование рееÑтра адаптеров =============================== Данный документ Ñодержит небольшую демонÑтрацию пакета ``zope.interface`` и его рееÑтра адаптеров. Документ раÑÑчитывалÑÑ ÐºÐ°Ðº конкретный, но более узкий пример того как иÑпользовать интерфейÑÑ‹ и адаптеры вне Zope 3. Сначала нам необходимо импортировать пакет Ð´Ð»Ñ Ñ€Ð°Ð±Ð¾Ñ‚Ñ‹ Ñ Ð¸Ð½Ñ‚ÐµÑ€Ñ„ÐµÐ¹Ñами:: >>> import zope.interface Теперь мы разработаем Ð¸Ð½Ñ‚ÐµÑ€Ñ„ÐµÐ¹Ñ Ð´Ð»Ñ Ð½Ð°ÑˆÐµÐ³Ð¾ объекта - проÑтого файла. Ðаш файл будет Ñодержать вÑего один атрибут - body, в котором фактичеÑки будет Ñохранено Ñодержимое файла:: >>> class IFile(zope.interface.Interface): ... ... body = zope.interface.Attribute(u'Содержимое файла.') ... Ð”Ð»Ñ ÑтатиÑтики нам чаÑто необходимо знать размер файла. Ðо было бы неÑколько топорно реализовывать определение размера прÑмо Ð´Ð»Ñ Ð¾Ð±ÑŠÐµÐºÑ‚Ð° файла, Ñ‚.к. размер больше отноÑитÑÑ Ðº мета-данным. Таким образом мы Ñоздаем еще один Ð¸Ð½Ñ‚ÐµÑ€Ñ„ÐµÐ¹Ñ Ð´Ð»Ñ Ð¿Ñ€ÐµÐ´ÑÑ‚Ð°Ð²Ð»ÐµÐ½Ð¸Ñ Ñ€Ð°Ð·Ð¼ÐµÑ€Ð° какого-либо объекта:: >>> class ISize(zope.interface.Interface): ... ... def getSize(): ... 'Return the size of an object.' ... Теперь мы должны Ñоздать клаÑÑ Ñ€ÐµÐ°Ð»Ð¸Ð·ÑƒÑŽÑ‰Ð¸Ð¹ наш файл. Ðеобходимо что бы наш объект хранил информацию о том, что он реализует Ð¸Ð½Ñ‚ÐµÑ€Ñ„ÐµÐ¹Ñ `IFile`. Мы также Ñоздаем атрибут Ñ Ñодержимым файла по умолчанию (Ð´Ð»Ñ ÑƒÐ¿Ñ€Ð¾Ñ‰ÐµÐ½Ð¸Ñ Ð½Ð°ÑˆÐµÐ³Ð¾ примера):: >>> class File(object): ... ... zope.interface.implements(IFile) ... body = 'foo bar' ... Дальше мы Ñоздаем адаптер, который будет предоÑтавлÑÑ‚ÑŒ Ð¸Ð½Ñ‚ÐµÑ€Ñ„ÐµÐ¹Ñ `ISize` Ð¿Ð¾Ð»ÑƒÑ‡Ð°Ñ Ð»ÑŽÐ±Ð¾Ð¹ объект предоÑтавлÑющий Ð¸Ð½Ñ‚ÐµÑ€Ñ„ÐµÐ¹Ñ `IFile`. По Ñоглашению мы иÑпользуем атрибут `__used_for__` Ð´Ð»Ñ ÑƒÐºÐ°Ð·Ð°Ð½Ð¸Ñ Ð¸Ð½Ñ‚ÐµÑ€Ñ„ÐµÐ¹Ñа который как мы ожидаем предоÑтавлÑет адаптируемый объект, `IFile` в нашем Ñлучае. Ðа Ñамом деле Ñтот атрибут иÑпользуетÑÑ Ñ‚Ð¾Ð»ÑŒÐºÐ¾ Ð´Ð»Ñ Ð´Ð¾ÐºÑƒÐ¼ÐµÐ½Ñ‚Ð¸Ñ€Ð¾Ð²Ð°Ð½Ð¸Ñ. Ð’ Ñлучае еÑли адаптер иÑпользуетÑÑ Ð´Ð»Ñ Ð½ÐµÑкольких интерфейÑов можно указать их вÑе в виде кортежа. ОпÑÑ‚ÑŒ же по Ñоглашению конÑтруктор адаптера получает один аргумент - context (контекÑÑ‚). Ð’ нашем Ñлучае контекÑÑ‚ - Ñто ÑкземплÑÑ€ `IFile` (объект, предоÑтавлÑющий `IFile`) который иÑпользуетÑÑ Ð´Ð»Ñ Ð¿Ð¾Ð»ÑƒÑ‡ÐµÐ½Ð¸Ñ Ð¸Ð· него размера. Так же по Ñоглашению контекÑÑ‚ ÑохранÑетÑÑ Ð° адаптере в атрибуте Ñ Ð¸Ð¼ÐµÐ½ÐµÐ¼ `context`. Twisted комьюнити ÑÑылаетÑÑ Ð½Ð° контекÑÑ‚ как на объект `original`. Таким образом можно также дать аргументу любое подходÑщее имÑ, например `file`:: >>> class FileSize(object): ... ... zope.interface.implements(ISize) ... __used_for__ = IFile ... ... def __init__(self, context): ... self.context = context ... ... def getSize(self): ... return len(self.context.body) ... Теперь когда мы напиÑали наш адаптер мы должны зарегиÑтрировать его в рееÑтре адаптеров, что бы его можно было запроÑить когда он понадобитÑÑ. ЗдеÑÑŒ нет какого-либо глобального рееÑтра адаптеров, таким образом мы должны ÑамоÑтоÑтельно Ñоздать Ð´Ð»Ñ Ð½Ð°ÑˆÐµÐ³Ð¾ примера рееÑÑ‚Ñ€:: >>> from zope.interface.adapter import AdapterRegistry >>> registry = AdapterRegistry() РееÑÑ‚Ñ€ Ñодержит отображение того, что адаптер реализует на оÑнове другого интерфейÑа который предоÑтавлÑет объект. ПоÑтому дальше мы региÑтрируем адаптер который адаптирует Ð¸Ð½Ñ‚ÐµÑ€Ñ„ÐµÐ¹Ñ `IFile` к интерфейÑу `ISize`. Первый аргумент к методу `register()` рееÑтра - Ñто ÑпиÑок адаптируемых интерфейÑов. Ð’ нашем Ñлучае мы имеем только один адаптируемый Ð¸Ð½Ñ‚ÐµÑ€Ñ„ÐµÐ¹Ñ - `IFile`. СпиÑок интерфейÑов имеет ÑмыÑл Ð´Ð»Ñ Ð¸ÑÐ¿Ð¾Ð»ÑŒÐ·Ð¾Ð²Ð°Ð½Ð¸Ñ ÐºÐ¾Ð½Ñ†ÐµÐ¿Ñ†Ð¸Ð¸ мульти-адаптеров, которые требуют неÑкольких оригинальных объектов Ð´Ð»Ñ Ð°Ð´Ð°Ð¿Ñ‚Ð°Ñ†Ð¸Ð¸ к новому интерфейÑу. Ð’ Ñтой Ñитуации конÑтруктор адаптера будет требовать новый аргумент Ð´Ð»Ñ ÐºÐ°Ð¶Ð´Ð¾Ð³Ð¾ оригинального интерфейÑа. Второй аргумент метода `register()` - Ñто Ð¸Ð½Ñ‚ÐµÑ€Ñ„ÐµÐ¹Ñ ÐºÐ¾Ñ‚Ð¾Ñ€Ñ‹Ð¹ предоÑтавлÑет адаптер, в нашем Ñлучае `ISize`. Третий аргумент - Ð¸Ð¼Ñ Ð°Ð´Ð°Ð¿Ñ‚ÐµÑ€Ð°. Ð¡ÐµÐ¹Ñ‡Ð°Ñ Ð½Ð°Ð¼ не важно Ð¸Ð¼Ñ Ð°Ð´Ð°Ð¿Ñ‚ÐµÑ€Ð° и мы передаем его как пуÑтую Ñтроку. Обычно имена полезны еÑли иÑпользуютÑÑ Ð°Ð´Ð°Ð¿Ñ‚ÐµÑ€Ñ‹ Ð´Ð»Ñ Ð¾Ð´Ð¸Ð½Ð°ÐºÐ¾Ð²Ð¾Ð³Ð¾ набора интерфейÑов, но в различных ÑитуациÑÑ…. ПоÑледний аргумент - Ñто клаÑÑ Ð°Ð´Ð°Ð¿Ñ‚ÐµÑ€Ð°:: >>> registry.register([IFile], ISize, '', FileSize) Теперь мы можем иÑпользовать рееÑÑ‚Ñ€ Ð´Ð»Ñ Ð·Ð°Ð¿Ñ€Ð¾Ñа адаптера:: >>> registry.lookup1(IFile, ISize, '') Попробуем более практичный пример. Создадим ÑкземплÑÑ€ `File` и Ñоздадим адаптер иÑпользующий Ð·Ð°Ð¿Ñ€Ð¾Ñ Ñ€ÐµÐµÑтра. Затем мы увидим возвращает ли адаптер корректный размер при вызове `getSize()`:: >>> file = File() >>> size = registry.lookup1(IFile, ISize, '')(file) >>> size.getSize() 7 Ðа Ñамом деле Ñто не очень практично, Ñ‚.к. нам нужно Ñамим передавать вÑе аргументы методу запроÑа. СущеÑтвует некоторый ÑинтакÑичеÑкий леденец который позволÑет нам получить ÑкземплÑÑ€ адаптера проÑто вызвав `ISize(file)`. Что бы иÑпользовать Ñту функциональноÑÑ‚ÑŒ нам понадобитÑÑ Ð´Ð¾Ð±Ð°Ð²Ð¸Ñ‚ÑŒ наш рееÑÑ‚Ñ€ к ÑпиÑку adapter_hooks, который находитÑÑ Ð² модуле Ñ Ð°Ð´Ð°Ð¿Ñ‚ÐµÑ€Ð°Ð¼Ð¸. Этот ÑпиÑок хранит коллекцию вызываемых объектов которые вызываютÑÑ Ð°Ð²Ñ‚Ð¾Ð¼Ð°Ñ‚Ð¸Ñ‡ÐµÑки когда вызываетÑÑ IFoo(obj); их предназначение - найти адаптеры которые реализуют Ð¸Ð½Ñ‚ÐµÑ€Ñ„ÐµÐ¹Ñ Ð´Ð»Ñ Ð¾Ð¿Ñ€ÐµÐ´ÐµÐ»ÐµÐ½Ð½Ð¾Ð³Ð¾ ÑкземплÑра контекÑта. Ðеобходимо реализовать Ñвою ÑобÑтвенную функцию Ð´Ð»Ñ Ð¿Ð¾Ð¸Ñка адаптера; данный пример опиÑывает одну из проÑтейших функций Ð´Ð»Ñ Ð¸ÑÐ¿Ð¾Ð»ÑŒÐ·Ð¾Ð²Ð°Ð½Ð¸Ñ Ñ Ñ€ÐµÐµÑтром, но также можно реализовать поиÑковые функции которые, например, иÑпользуют кÑширование, или адаптеры ÑохранÑемые в базе. Ð¤ÑƒÐ½ÐºÑ†Ð¸Ñ Ð¿Ð¾Ð¸Ñка должна принимать желаемый на выходе Ð¸Ð½Ñ‚ÐµÑ€Ñ„ÐµÐ¹Ñ (в нашем Ñлучае `ISize`) как первый аргумент и контекÑÑ‚ Ð´Ð»Ñ Ð°Ð´Ð°Ð¿Ñ‚Ð°Ñ†Ð¸Ð¸ (`file`) как второй. Ð¤ÑƒÐ½ÐºÑ†Ð¸Ñ Ð´Ð¾Ð»Ð¶Ð½Ð° вернуть адаптер, Ñ‚.е. ÑкземплÑÑ€ `FileSize`:: >>> def hook(provided, object): ... adapter = registry.lookup1(zope.interface.providedBy(object), ... provided, '') ... return adapter(object) ... Теперь мы проÑто добавлÑем нашу функцию к ÑпиÑку `adapter_hooks`:: >>> from zope.interface.interface import adapter_hooks >>> adapter_hooks.append(hook) Как только Ñ„ÑƒÐ½ÐºÑ†Ð¸Ñ Ð·Ð°Ñ€ÐµÐ³Ð¸Ñтрирована мы можем иÑпользовать желаемый ÑинтакÑиÑ:: >>> size = ISize(file) >>> size.getSize() 7 ПоÑле нам нужно прибратьÑÑ Ð·Ð° Ñобой, что бы другие получили чиÑтый ÑпиÑок `adaper_hooks` поÑле наÑ:: >>> adapter_hooks.remove(hook) Это вÑе.

It is maintained by the* `Zope Toolkit project `_. This package provides an implementation of `object interfaces` for Python. Interfaces are a mechanism for labeling objects as conforming to a given API or contract. So, this package can be considered as implementation of the `Design By Contract`_ methodology support in Python. .. _Design By Contract: http://en.wikipedia.org/wiki/Design_by_contract Detailed Documentation ********************** .. contents:: ========== Interfaces ========== Interfaces are objects that specify (document) the external behavior of objects that "provide" them. An interface specifies behavior through: - Informal documentation in a doc string - Attribute definitions - Invariants, which are conditions that must hold for objects that provide the interface Attribute definitions specify specific attributes. They define the attribute name and provide documentation and constraints of attribute values. Attribute definitions can take a number of forms, as we'll see below. Defining interfaces =================== Interfaces are defined using Python class statements:: >>> import zope.interface >>> class IFoo(zope.interface.Interface): ... """Foo blah blah""" ... ... x = zope.interface.Attribute("""X blah blah""") ... ... def bar(q, r=None): ... """bar blah blah""" In the example above, we've created an interface, `IFoo`. We subclassed `zope.interface.Interface`, which is an ancestor interface for all interfaces, much as `object` is an ancestor of all new-style classes [#create]_. The interface is not a class, it's an Interface, an instance of `InterfaceClass`:: >>> type(IFoo) We can ask for the interface's documentation:: >>> IFoo.__doc__ 'Foo blah blah' and its name:: >>> IFoo.__name__ 'IFoo' and even its module:: >>> IFoo.__module__ '__main__' The interface defined two attributes: `x` This is the simplest form of attribute definition. It has a name and a doc string. It doesn't formally specify anything else. `bar` This is a method. A method is defined via a function definition. A method is simply an attribute constrained to be a callable with a particular signature, as provided by the function definition. Note that `bar` doesn't take a `self` argument. Interfaces document how an object is *used*. When calling instance methods, you don't pass a `self` argument, so a `self` argument isn't included in the interface signature. The `self` argument in instance methods is really an implementation detail of Python instances. Other objects, besides instances can provide interfaces and their methods might not be instance methods. For example, modules can provide interfaces and their methods are usually just functions. Even instances can have methods that are not instance methods. You can access the attributes defined by an interface using mapping syntax:: >>> x = IFoo['x'] >>> type(x) >>> x.__name__ 'x' >>> x.__doc__ 'X blah blah' >>> IFoo.get('x').__name__ 'x' >>> IFoo.get('y') You can use `in` to determine if an interface defines a name:: >>> 'x' in IFoo True You can iterate over interfaces to get the names they define:: >>> names = list(IFoo) >>> names.sort() >>> names ['bar', 'x'] Remember that interfaces aren't classes. You can't access attribute definitions as attributes of interfaces:: >>> IFoo.x Traceback (most recent call last): File "", line 1, in ? AttributeError: 'InterfaceClass' object has no attribute 'x' Methods provide access to the method signature:: >>> bar = IFoo['bar'] >>> bar.getSignatureString() '(q, r=None)' TODO Methods really should have a better API. This is something that needs to be improved. Declaring interfaces ==================== Having defined interfaces, we can *declare* that objects provide them. Before we describe the details, lets define some terms: *provide* We say that objects *provide* interfaces. If an object provides an interface, then the interface specifies the behavior of the object. In other words, interfaces specify the behavior of the objects that provide them. *implement* We normally say that classes *implement* interfaces. If a class implements an interface, then the instances of the class provide the interface. Objects provide interfaces that their classes implement [#factory]_. (Objects can provide interfaces directly, in addition to what their classes implement.) It is important to note that classes don't usually provide the interfaces that they implement. We can generalize this to factories. For any callable object we can declare that it produces objects that provide some interfaces by saying that the factory implements the interfaces. Now that we've defined these terms, we can talk about the API for declaring interfaces. Declaring implemented interfaces -------------------------------- The most common way to declare interfaces is using the implements function in a class statement:: >>> class Foo: ... zope.interface.implements(IFoo) ... ... def __init__(self, x=None): ... self.x = x ... ... def bar(self, q, r=None): ... return q, r, self.x ... ... def __repr__(self): ... return "Foo(%s)" % self.x In this example, we declared that `Foo` implements `IFoo`. This means that instances of `Foo` provide `IFoo`. Having made this declaration, there are several ways we can introspect the declarations. First, we can ask an interface whether it is implemented by a class:: >>> IFoo.implementedBy(Foo) True And we can ask whether an interface is provided by an object:: >>> foo = Foo() >>> IFoo.providedBy(foo) True Of course, `Foo` doesn't provide `IFoo`, it implements it:: >>> IFoo.providedBy(Foo) False We can also ask what interfaces are implemented by an object:: >>> list(zope.interface.implementedBy(Foo)) [] It's an error to ask for interfaces implemented by a non-callable object:: >>> IFoo.implementedBy(foo) Traceback (most recent call last): ... TypeError: ('ImplementedBy called for non-factory', Foo(None)) >>> list(zope.interface.implementedBy(foo)) Traceback (most recent call last): ... TypeError: ('ImplementedBy called for non-factory', Foo(None)) Similarly, we can ask what interfaces are provided by an object:: >>> list(zope.interface.providedBy(foo)) [] >>> list(zope.interface.providedBy(Foo)) [] We can declare interfaces implemented by other factories (besides classes). We do this using a Python-2.4-style decorator named `implementer`. In versions of Python before 2.4, this looks like:: >>> def yfoo(y): ... foo = Foo() ... foo.y = y ... return foo >>> yfoo = zope.interface.implementer(IFoo)(yfoo) >>> list(zope.interface.implementedBy(yfoo)) [] Note that the implementer decorator may modify it's argument. Callers should not assume that a new object is created. Using implementer also works on callable objects. This is used by zope.formlib, as an example. >>> class yfactory: ... def __call__(self, y): ... foo = Foo() ... foo.y = y ... return foo >>> yfoo = yfactory() >>> yfoo = zope.interface.implementer(IFoo)(yfoo) >>> list(zope.interface.implementedBy(yfoo)) [] XXX: Double check and update these version numbers: In zope.interface 3.5.2 and lower, the implementor decorator can not be used for classes, but in 3.6.0 and higher it can: >>> Foo = zope.interface.implementer(IFoo)(Foo) >>> list(zope.interface.providedBy(Foo())) [] Note that class decorators using the @implementor(IFoo) syntax are only supported in Python 2.6 and later. Declaring provided interfaces ----------------------------- We can declare interfaces directly provided by objects. Suppose that we want to document what the `__init__` method of the `Foo` class does. It's not *really* part of `IFoo`. You wouldn't normally call the `__init__` method on Foo instances. Rather, the `__init__` method is part of the `Foo`'s `__call__` method:: >>> class IFooFactory(zope.interface.Interface): ... """Create foos""" ... ... def __call__(x=None): ... """Create a foo ... ... The argument provides the initial value for x ... ... """ It's the class that provides this interface, so we declare the interface on the class:: >>> zope.interface.directlyProvides(Foo, IFooFactory) And then, we'll see that Foo provides some interfaces:: >>> list(zope.interface.providedBy(Foo)) [] >>> IFooFactory.providedBy(Foo) True Declaring class interfaces is common enough that there's a special declaration function for it, `classProvides`, that allows the declaration from within a class statement:: >>> class Foo2: ... zope.interface.implements(IFoo) ... zope.interface.classProvides(IFooFactory) ... ... def __init__(self, x=None): ... self.x = x ... ... def bar(self, q, r=None): ... return q, r, self.x ... ... def __repr__(self): ... return "Foo(%s)" % self.x >>> list(zope.interface.providedBy(Foo2)) [] >>> IFooFactory.providedBy(Foo2) True There's a similar function, `moduleProvides`, that supports interface declarations from within module definitions. For example, see the use of `moduleProvides` call in `zope.interface.__init__`, which declares that the package `zope.interface` provides `IInterfaceDeclaration`. Sometimes, we want to declare interfaces on instances, even though those instances get interfaces from their classes. Suppose we create a new interface, `ISpecial`:: >>> class ISpecial(zope.interface.Interface): ... reason = zope.interface.Attribute("Reason why we're special") ... def brag(): ... "Brag about being special" We can make an existing foo instance special by providing `reason` and `brag` attributes:: >>> foo.reason = 'I just am' >>> def brag(): ... return "I'm special!" >>> foo.brag = brag >>> foo.reason 'I just am' >>> foo.brag() "I'm special!" and by declaring the interface:: >>> zope.interface.directlyProvides(foo, ISpecial) then the new interface is included in the provided interfaces:: >>> ISpecial.providedBy(foo) True >>> list(zope.interface.providedBy(foo)) [, ] We can find out what interfaces are directly provided by an object:: >>> list(zope.interface.directlyProvidedBy(foo)) [] >>> newfoo = Foo() >>> list(zope.interface.directlyProvidedBy(newfoo)) [] Inherited declarations ---------------------- Normally, declarations are inherited:: >>> class SpecialFoo(Foo): ... zope.interface.implements(ISpecial) ... reason = 'I just am' ... def brag(self): ... return "I'm special because %s" % self.reason >>> list(zope.interface.implementedBy(SpecialFoo)) [, ] >>> list(zope.interface.providedBy(SpecialFoo())) [, ] Sometimes, you don't want to inherit declarations. In that case, you can use `implementsOnly`, instead of `implements`:: >>> class Special(Foo): ... zope.interface.implementsOnly(ISpecial) ... reason = 'I just am' ... def brag(self): ... return "I'm special because %s" % self.reason >>> list(zope.interface.implementedBy(Special)) [] >>> list(zope.interface.providedBy(Special())) [] External declarations --------------------- Normally, we make implementation declarations as part of a class definition. Sometimes, we may want to make declarations from outside the class definition. For example, we might want to declare interfaces for classes that we didn't write. The function `classImplements` can be used for this purpose:: >>> class C: ... pass >>> zope.interface.classImplements(C, IFoo) >>> list(zope.interface.implementedBy(C)) [] We can use `classImplementsOnly` to exclude inherited interfaces:: >>> class C(Foo): ... pass >>> zope.interface.classImplementsOnly(C, ISpecial) >>> list(zope.interface.implementedBy(C)) [] Declaration Objects ------------------- When we declare interfaces, we create *declaration* objects. When we query declarations, declaration objects are returned:: >>> type(zope.interface.implementedBy(Special)) Declaration objects and interface objects are similar in many ways. In fact, they share a common base class. The important thing to realize about them is that they can be used where interfaces are expected in declarations. Here's a silly example:: >>> class Special2(Foo): ... zope.interface.implementsOnly( ... zope.interface.implementedBy(Foo), ... ISpecial, ... ) ... reason = 'I just am' ... def brag(self): ... return "I'm special because %s" % self.reason The declaration here is almost the same as ``zope.interface.implements(ISpecial)``, except that the order of interfaces in the resulting declaration is different:: >>> list(zope.interface.implementedBy(Special2)) [, ] Interface Inheritance ===================== Interfaces can extend other interfaces. They do this simply by listing the other interfaces as base interfaces:: >>> class IBlat(zope.interface.Interface): ... """Blat blah blah""" ... ... y = zope.interface.Attribute("y blah blah") ... def eek(): ... """eek blah blah""" >>> IBlat.__bases__ (,) >>> class IBaz(IFoo, IBlat): ... """Baz blah""" ... def eek(a=1): ... """eek in baz blah""" ... >>> IBaz.__bases__ (, ) >>> names = list(IBaz) >>> names.sort() >>> names ['bar', 'eek', 'x', 'y'] Note that `IBaz` overrides eek:: >>> IBlat['eek'].__doc__ 'eek blah blah' >>> IBaz['eek'].__doc__ 'eek in baz blah' We were careful to override eek in a compatible way. When extending an interface, the extending interface should be compatible [#compat]_ with the extended interfaces. We can ask whether one interface extends another:: >>> IBaz.extends(IFoo) True >>> IBlat.extends(IFoo) False Note that interfaces don't extend themselves:: >>> IBaz.extends(IBaz) False Sometimes we wish they did, but we can, instead use `isOrExtends`:: >>> IBaz.isOrExtends(IBaz) True >>> IBaz.isOrExtends(IFoo) True >>> IFoo.isOrExtends(IBaz) False When we iterate over an interface, we get all of the names it defines, including names defined by base interfaces. Sometimes, we want *just* the names defined by the interface directly. We bane use the `names` method for that:: >>> list(IBaz.names()) ['eek'] Inheritance of attribute specifications --------------------------------------- An interface may override attribute definitions from base interfaces. If two base interfaces define the same attribute, the attribute is inherited from the most specific interface. For example, with:: >>> class IBase(zope.interface.Interface): ... ... def foo(): ... "base foo doc" >>> class IBase1(IBase): ... pass >>> class IBase2(IBase): ... ... def foo(): ... "base2 foo doc" >>> class ISub(IBase1, IBase2): ... pass ISub's definition of foo is the one from IBase2, since IBase2 is more specific that IBase:: >>> ISub['foo'].__doc__ 'base2 foo doc' Note that this differs from a depth-first search. Sometimes, it's useful to ask whether an interface defines an attribute directly. You can use the direct method to get a directly defined definitions:: >>> IBase.direct('foo').__doc__ 'base foo doc' >>> ISub.direct('foo') Specifications -------------- Interfaces and declarations are both special cases of specifications. What we described above for interface inheritance applies to both declarations and specifications. Declarations actually extend the interfaces that they declare:: >>> class Baz(object): ... zope.interface.implements(IBaz) >>> baz_implements = zope.interface.implementedBy(Baz) >>> baz_implements.__bases__ (, ) >>> baz_implements.extends(IFoo) True >>> baz_implements.isOrExtends(IFoo) True >>> baz_implements.isOrExtends(baz_implements) True Specifications (interfaces and declarations) provide an `__sro__` that lists the specification and all of it's ancestors:: >>> baz_implements.__sro__ (, , , , , ) Tagged Values ============= Interfaces and attribute descriptions support an extension mechanism, borrowed from UML, called "tagged values" that lets us store extra data:: >>> IFoo.setTaggedValue('date-modified', '2004-04-01') >>> IFoo.setTaggedValue('author', 'Jim Fulton') >>> IFoo.getTaggedValue('date-modified') '2004-04-01' >>> IFoo.queryTaggedValue('date-modified') '2004-04-01' >>> IFoo.queryTaggedValue('datemodified') >>> tags = list(IFoo.getTaggedValueTags()) >>> tags.sort() >>> tags ['author', 'date-modified'] Function attributes are converted to tagged values when method attribute definitions are created:: >>> class IBazFactory(zope.interface.Interface): ... def __call__(): ... "create one" ... __call__.return_type = IBaz >>> IBazFactory['__call__'].getTaggedValue('return_type') Tagged values can also be defined from within an interface definition:: >>> class IWithTaggedValues(zope.interface.Interface): ... zope.interface.taggedValue('squish', 'squash') >>> IWithTaggedValues.getTaggedValue('squish') 'squash' Invariants ========== Interfaces can express conditions that must hold for objects that provide them. These conditions are expressed using one or more invariants. Invariants are callable objects that will be called with an object that provides an interface. An invariant raises an `Invalid` exception if the condition doesn't hold. Here's an example:: >>> class RangeError(zope.interface.Invalid): ... """A range has invalid limits""" ... def __repr__(self): ... return "RangeError(%r)" % self.args >>> def range_invariant(ob): ... if ob.max < ob.min: ... raise RangeError(ob) Given this invariant, we can use it in an interface definition:: >>> class IRange(zope.interface.Interface): ... min = zope.interface.Attribute("Lower bound") ... max = zope.interface.Attribute("Upper bound") ... ... zope.interface.invariant(range_invariant) Interfaces have a method for checking their invariants:: >>> class Range(object): ... zope.interface.implements(IRange) ... ... def __init__(self, min, max): ... self.min, self.max = min, max ... ... def __repr__(self): ... return "Range(%s, %s)" % (self.min, self.max) >>> IRange.validateInvariants(Range(1,2)) >>> IRange.validateInvariants(Range(1,1)) >>> IRange.validateInvariants(Range(2,1)) Traceback (most recent call last): ... RangeError: Range(2, 1) If you have multiple invariants, you may not want to stop checking after the first error. If you pass a list to `validateInvariants`, then a single `Invalid` exception will be raised with the list of exceptions as it's argument:: >>> from zope.interface.exceptions import Invalid >>> errors = [] >>> try: ... IRange.validateInvariants(Range(2,1), errors) ... except Invalid, e: ... str(e) '[RangeError(Range(2, 1))]' And the list will be filled with the individual exceptions:: >>> errors [RangeError(Range(2, 1))] >>> del errors[:] Adaptation ========== Interfaces can be called to perform adaptation. The semantics are based on those of the PEP 246 adapt function. If an object cannot be adapted, then a TypeError is raised:: >>> class I(zope.interface.Interface): ... pass >>> I(0) Traceback (most recent call last): ... TypeError: ('Could not adapt', 0, ) unless an alternate value is provided as a second positional argument:: >>> I(0, 'bob') 'bob' If an object already implements the interface, then it will be returned:: >>> class C(object): ... zope.interface.implements(I) >>> obj = C() >>> I(obj) is obj True If an object implements __conform__, then it will be used:: >>> class C(object): ... zope.interface.implements(I) ... def __conform__(self, proto): ... return 0 >>> I(C()) 0 Adapter hooks (see __adapt__) will also be used, if present:: >>> from zope.interface.interface import adapter_hooks >>> def adapt_0_to_42(iface, obj): ... if obj == 0: ... return 42 >>> adapter_hooks.append(adapt_0_to_42) >>> I(0) 42 >>> adapter_hooks.remove(adapt_0_to_42) >>> I(0) Traceback (most recent call last): ... TypeError: ('Could not adapt', 0, ) __adapt__ --------- >>> class I(zope.interface.Interface): ... pass Interfaces implement the PEP 246 __adapt__ method. This method is normally not called directly. It is called by the PEP 246 adapt framework and by the interface __call__ operator. The adapt method is responsible for adapting an object to the reciever. The default version returns None:: >>> I.__adapt__(0) unless the object given provides the interface:: >>> class C(object): ... zope.interface.implements(I) >>> obj = C() >>> I.__adapt__(obj) is obj True Adapter hooks can be provided (or removed) to provide custom adaptation. We'll install a silly hook that adapts 0 to 42. We install a hook by simply adding it to the adapter_hooks list:: >>> from zope.interface.interface import adapter_hooks >>> def adapt_0_to_42(iface, obj): ... if obj == 0: ... return 42 >>> adapter_hooks.append(adapt_0_to_42) >>> I.__adapt__(0) 42 Hooks must either return an adapter, or None if no adapter can be found. Hooks can be uninstalled by removing them from the list:: >>> adapter_hooks.remove(adapt_0_to_42) >>> I.__adapt__(0) .. [#create] The main reason we subclass `Interface` is to cause the Python class statement to create an interface, rather than a class. It's possible to create interfaces by calling a special interface class directly. Doing this, it's possible (and, on rare occasions, useful) to create interfaces that don't descend from `Interface`. Using this technique is beyond the scope of this document. .. [#factory] Classes are factories. They can be called to create their instances. We expect that we will eventually extend the concept of implementation to other kinds of factories, so that we can declare the interfaces provided by the objects created. .. [#compat] The goal is substitutability. An object that provides an extending interface should be substitutable for an object that provides the extended interface. In our example, an object that provides IBaz should be usable whereever an object that provides IBlat is expected. The interface implementation doesn't enforce this. but maybe it should do some checks. ================ Adapter Registry ================ Adapter registries provide a way to register objects that depend on one or more interface specifications and provide (perhaps indirectly) some interface. In addition, the registrations have names. (You can think of the names as qualifiers of the provided interfaces.) The term "interface specification" refers both to interfaces and to interface declarations, such as declarations of interfaces implemented by a class. Single Adapters =============== Let's look at a simple example, using a single required specification:: >>> from zope.interface.adapter import AdapterRegistry >>> import zope.interface >>> class IR1(zope.interface.Interface): ... pass >>> class IP1(zope.interface.Interface): ... pass >>> class IP2(IP1): ... pass >>> registry = AdapterRegistry() We'll register an object that depends on IR1 and "provides" IP2:: >>> registry.register([IR1], IP2, '', 12) Given the registration, we can look it up again:: >>> registry.lookup([IR1], IP2, '') 12 Note that we used an integer in the example. In real applications, one would use some objects that actually depend on or provide interfaces. The registry doesn't care about what gets registered, so we'll use integers and strings to keep the examples simple. There is one exception. Registering a value of None unregisters any previously-registered value. If an object depends on a specification, it can be looked up with a specification that extends the specification that it depends on:: >>> class IR2(IR1): ... pass >>> registry.lookup([IR2], IP2, '') 12 We can use a class implementation specification to look up the object:: >>> class C2: ... zope.interface.implements(IR2) >>> registry.lookup([zope.interface.implementedBy(C2)], IP2, '') 12 and it can be looked up for interfaces that its provided interface extends:: >>> registry.lookup([IR1], IP1, '') 12 >>> registry.lookup([IR2], IP1, '') 12 But if you require a specification that doesn't extend the specification the object depends on, you won't get anything:: >>> registry.lookup([zope.interface.Interface], IP1, '') By the way, you can pass a default value to lookup:: >>> registry.lookup([zope.interface.Interface], IP1, '', 42) 42 If you try to get an interface the object doesn't provide, you also won't get anything:: >>> class IP3(IP2): ... pass >>> registry.lookup([IR1], IP3, '') You also won't get anything if you use the wrong name:: >>> registry.lookup([IR1], IP1, 'bob') >>> registry.register([IR1], IP2, 'bob', "Bob's 12") >>> registry.lookup([IR1], IP1, 'bob') "Bob's 12" You can leave the name off when doing a lookup:: >>> registry.lookup([IR1], IP1) 12 If we register an object that provides IP1:: >>> registry.register([IR1], IP1, '', 11) then that object will be prefered over O(12):: >>> registry.lookup([IR1], IP1, '') 11 Also, if we register an object for IR2, then that will be prefered when using IR2:: >>> registry.register([IR2], IP1, '', 21) >>> registry.lookup([IR2], IP1, '') 21 Finding out what, if anything, is registered -------------------------------------------- We can ask if there is an adapter registered for a collection of interfaces. This is different than lookup, because it looks for an exact match. >>> print registry.registered([IR1], IP1) 11 >>> print registry.registered([IR1], IP2) 12 >>> print registry.registered([IR1], IP2, 'bob') Bob's 12 >>> print registry.registered([IR2], IP1) 21 >>> print registry.registered([IR2], IP2) None In the last example, None was returned because nothing was registered exactly for the given interfaces. lookup1 ------- Lookup of single adapters is common enough that there is a specialized version of lookup that takes a single required interface:: >>> registry.lookup1(IR2, IP1, '') 21 >>> registry.lookup1(IR2, IP1) 21 Actual Adaptation ----------------- The adapter registry is intended to support adaptation, where one object that implements an interface is adapted to another object that supports a different interface. The adapter registry supports the computation of adapters. In this case, we have to register adapter factories:: >>> class IR(zope.interface.Interface): ... pass >>> class X: ... zope.interface.implements(IR) >>> class Y: ... zope.interface.implements(IP1) ... def __init__(self, context): ... self.context = context >>> registry.register([IR], IP1, '', Y) In this case, we registered a class as the factory. Now we can call `queryAdapter` to get the adapted object:: >>> x = X() >>> y = registry.queryAdapter(x, IP1) >>> y.__class__.__name__ 'Y' >>> y.context is x True We can register and lookup by name too:: >>> class Y2(Y): ... pass >>> registry.register([IR], IP1, 'bob', Y2) >>> y = registry.queryAdapter(x, IP1, 'bob') >>> y.__class__.__name__ 'Y2' >>> y.context is x True When the adapter factory produces `None`, then this is treated as if no adapter has been found. This allows us to prevent adaptation (when desired) and let the adapter factory determine whether adaptation is possible based on the state of the object being adapted. >>> def factory(context): ... if context.name == 'object': ... return 'adapter' ... return None >>> class Object(object): ... zope.interface.implements(IR) ... name = 'object' >>> registry.register([IR], IP1, 'conditional', factory) >>> obj = Object() >>> registry.queryAdapter(obj, IP1, 'conditional') 'adapter' >>> obj.name = 'no object' >>> registry.queryAdapter(obj, IP1, 'conditional') is None True >>> registry.queryAdapter(obj, IP1, 'conditional', 'default') 'default' An alternate method that provides the same function as `queryAdapter()` is `adapter_hook()`:: >>> y = registry.adapter_hook(IP1, x) >>> y.__class__.__name__ 'Y' >>> y.context is x True >>> y = registry.adapter_hook(IP1, x, 'bob') >>> y.__class__.__name__ 'Y2' >>> y.context is x True The `adapter_hook()` simply switches the order of the object and interface arguments. It is used to hook into the interface call mechanism. Default Adapters ---------------- Sometimes, you want to provide an adapter that will adapt anything. For that, provide None as the required interface:: >>> registry.register([None], IP1, '', 1) then we can use that adapter for interfaces we don't have specific adapters for:: >>> class IQ(zope.interface.Interface): ... pass >>> registry.lookup([IQ], IP1, '') 1 Of course, specific adapters are still used when applicable:: >>> registry.lookup([IR2], IP1, '') 21 Class adapters -------------- You can register adapters for class declarations, which is almost the same as registering them for a class:: >>> registry.register([zope.interface.implementedBy(C2)], IP1, '', 'C21') >>> registry.lookup([zope.interface.implementedBy(C2)], IP1, '') 'C21' Dict adapters ------------- At some point it was impossible to register dictionary-based adapters due a bug. Let's make sure this works now: >>> adapter = {} >>> registry.register((), IQ, '', adapter) >>> registry.lookup((), IQ, '') is adapter True Unregistering ------------- You can unregister by registering None, rather than an object:: >>> registry.register([zope.interface.implementedBy(C2)], IP1, '', None) >>> registry.lookup([zope.interface.implementedBy(C2)], IP1, '') 21 Of course, this means that None can't be registered. This is an exception to the statement, made earlier, that the registry doesn't care what gets registered. Multi-adapters ============== You can adapt multiple specifications:: >>> registry.register([IR1, IQ], IP2, '', '1q2') >>> registry.lookup([IR1, IQ], IP2, '') '1q2' >>> registry.lookup([IR2, IQ], IP1, '') '1q2' >>> class IS(zope.interface.Interface): ... pass >>> registry.lookup([IR2, IS], IP1, '') >>> class IQ2(IQ): ... pass >>> registry.lookup([IR2, IQ2], IP1, '') '1q2' >>> registry.register([IR1, IQ2], IP2, '', '1q22') >>> registry.lookup([IR2, IQ2], IP1, '') '1q22' Multi-adaptation ---------------- You can adapt multiple objects:: >>> class Q: ... zope.interface.implements(IQ) As with single adapters, we register a factory, which is often a class:: >>> class IM(zope.interface.Interface): ... pass >>> class M: ... zope.interface.implements(IM) ... def __init__(self, x, q): ... self.x, self.q = x, q >>> registry.register([IR, IQ], IM, '', M) And then we can call `queryMultiAdapter` to compute an adapter:: >>> q = Q() >>> m = registry.queryMultiAdapter((x, q), IM) >>> m.__class__.__name__ 'M' >>> m.x is x and m.q is q True and, of course, we can use names:: >>> class M2(M): ... pass >>> registry.register([IR, IQ], IM, 'bob', M2) >>> m = registry.queryMultiAdapter((x, q), IM, 'bob') >>> m.__class__.__name__ 'M2' >>> m.x is x and m.q is q True Default Adapters ---------------- As with single adapters, you can define default adapters by specifying None for the *first* specification:: >>> registry.register([None, IQ], IP2, '', 'q2') >>> registry.lookup([IS, IQ], IP2, '') 'q2' Null Adapters ============= You can also adapt no specification:: >>> registry.register([], IP2, '', 2) >>> registry.lookup([], IP2, '') 2 >>> registry.lookup([], IP1, '') 2 Listing named adapters ---------------------- Adapters are named. Sometimes, it's useful to get all of the named adapters for given interfaces:: >>> adapters = list(registry.lookupAll([IR1], IP1)) >>> adapters.sort() >>> assert adapters == [(u'', 11), (u'bob', "Bob's 12")] This works for multi-adapters too:: >>> registry.register([IR1, IQ2], IP2, 'bob', '1q2 for bob') >>> adapters = list(registry.lookupAll([IR2, IQ2], IP1)) >>> adapters.sort() >>> assert adapters == [(u'', '1q22'), (u'bob', '1q2 for bob')] And even null adapters:: >>> registry.register([], IP2, 'bob', 3) >>> adapters = list(registry.lookupAll([], IP1)) >>> adapters.sort() >>> assert adapters == [(u'', 2), (u'bob', 3)] Subscriptions ============= Normally, we want to look up an object that most-closely matches a specification. Sometimes, we want to get all of the objects that match some specification. We use subscriptions for this. We subscribe objects against specifications and then later find all of the subscribed objects:: >>> registry.subscribe([IR1], IP2, 'sub12 1') >>> registry.subscriptions([IR1], IP2) ['sub12 1'] Note that, unlike regular adapters, subscriptions are unnamed. You can have multiple subscribers for the same specification:: >>> registry.subscribe([IR1], IP2, 'sub12 2') >>> registry.subscriptions([IR1], IP2) ['sub12 1', 'sub12 2'] If subscribers are registered for the same required interfaces, they are returned in the order of definition. You can register subscribers for all specifications using None:: >>> registry.subscribe([None], IP1, 'sub_1') >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2'] Note that the new subscriber is returned first. Subscribers defined for less general required interfaces are returned before subscribers for more general interfaces. Subscriptions may be combined over multiple compatible specifications:: >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2'] >>> registry.subscribe([IR1], IP1, 'sub11') >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2', 'sub11'] >>> registry.subscribe([IR2], IP2, 'sub22') >>> registry.subscriptions([IR2], IP1) ['sub_1', 'sub12 1', 'sub12 2', 'sub11', 'sub22'] >>> registry.subscriptions([IR2], IP2) ['sub12 1', 'sub12 2', 'sub22'] Subscriptions can be on multiple specifications:: >>> registry.subscribe([IR1, IQ], IP2, 'sub1q2') >>> registry.subscriptions([IR1, IQ], IP2) ['sub1q2'] As with single subscriptions and non-subscription adapters, you can specify None for the first required interface, to specify a default:: >>> registry.subscribe([None, IQ], IP2, 'sub_q2') >>> registry.subscriptions([IS, IQ], IP2) ['sub_q2'] >>> registry.subscriptions([IR1, IQ], IP2) ['sub_q2', 'sub1q2'] You can have subscriptions that are indepenent of any specifications:: >>> list(registry.subscriptions([], IP1)) [] >>> registry.subscribe([], IP2, 'sub2') >>> registry.subscriptions([], IP1) ['sub2'] >>> registry.subscribe([], IP1, 'sub1') >>> registry.subscriptions([], IP1) ['sub2', 'sub1'] >>> registry.subscriptions([], IP2) ['sub2'] Unregistering subscribers ------------------------- We can unregister subscribers. When unregistering a subscriber, we can unregister a specific subscriber:: >>> registry.unsubscribe([IR1], IP1, 'sub11') >>> registry.subscriptions([IR1], IP1) ['sub_1', 'sub12 1', 'sub12 2'] If we don't specify a value, then all subscribers matching the given interfaces will be unsubscribed: >>> registry.unsubscribe([IR1], IP2) >>> registry.subscriptions([IR1], IP1) ['sub_1'] Subscription adapters --------------------- We normally register adapter factories, which then allow us to compute adapters, but with subscriptions, we get multiple adapters. Here's an example of multiple-object subscribers:: >>> registry.subscribe([IR, IQ], IM, M) >>> registry.subscribe([IR, IQ], IM, M2) >>> subscribers = registry.subscribers((x, q), IM) >>> len(subscribers) 2 >>> class_names = [s.__class__.__name__ for s in subscribers] >>> class_names.sort() >>> class_names ['M', 'M2'] >>> [(s.x is x and s.q is q) for s in subscribers] [True, True] adapter factory subcribers can't return None values:: >>> def M3(x, y): ... return None >>> registry.subscribe([IR, IQ], IM, M3) >>> subscribers = registry.subscribers((x, q), IM) >>> len(subscribers) 2 Handlers -------- A handler is a subscriber factory that doesn't produce any normal output. It returns None. A handler is unlike adapters in that it does all of its work when the factory is called. To register a handler, simply provide None as the provided interface:: >>> def handler(event): ... print 'handler', event >>> registry.subscribe([IR1], None, handler) >>> registry.subscriptions([IR1], None) == [handler] True ========================== Using the Adapter Registry ========================== This is a small demonstration of the ``zope.interface`` package including its adapter registry. It is intended to provide a concrete but narrow example on how to use interfaces and adapters outside of Zope 3. First we have to import the interface package:: >>> import zope.interface We now develop an interface for our object, which is a simple file in this case. For now we simply support one attribute, the body, which contains the actual file contents:: >>> class IFile(zope.interface.Interface): ... ... body = zope.interface.Attribute('Contents of the file.') ... For statistical reasons we often want to know the size of a file. However, it would be clumsy to implement the size directly in the file object, since the size really represents meta-data. Thus we create another interface that provides the size of something:: >>> class ISize(zope.interface.Interface): ... ... def getSize(): ... 'Return the size of an object.' ... Now we need to implement the file. It is essential that the object states that it implements the `IFile` interface. We also provide a default body value (just to make things simpler for this example):: >>> class File(object): ... ... zope.interface.implements(IFile) ... body = 'foo bar' ... Next we implement an adapter that can provide the `ISize` interface given any object providing `IFile`. By convention we use `__used_for__` to specify the interface that we expect the adapted object to provide, in our case `IFile`. However, this attribute is not used for anything. If you have multiple interfaces for which an adapter is used, just specify the interfaces via a tuple. Again by convention, the constructor of an adapter takes one argument, the context. The context in this case is an instance of `File` (providing `IFile`) that is used to extract the size from. Also by convention the context is stored in an attribute named `context` on the adapter. The twisted community refers to the context as the `original` object. However, you may feel free to use a specific argument name, such as `file`:: >>> class FileSize(object): ... ... zope.interface.implements(ISize) ... __used_for__ = IFile ... ... def __init__(self, context): ... self.context = context ... ... def getSize(self): ... return len(self.context.body) ... Now that we have written our adapter, we have to register it with an adapter registry, so that it can be looked up when needed. There is no such thing as a global registry; thus we have to instantiate one for our example manually:: >>> from zope.interface.adapter import AdapterRegistry >>> registry = AdapterRegistry() The registry keeps a map of what adapters implement based on another interface, the object already provides. Therefore, we next have to register an adapter that adapts from `IFile` to `ISize`. The first argument to the registry's `register()` method is a list of original interfaces.In our cause we have only one original interface, `IFile`. A list makes sense, since the interface package has the concept of multi-adapters, which are adapters that require multiple objects to adapt to a new interface. In these situations, your adapter constructor will require an argument for each specified interface. The second argument is the interface the adapter provides, in our case `ISize`. The third argument is the name of the adapter. Since we do not care about names, we simply leave it as an empty string. Names are commonly useful, if you have adapters for the same set of interfaces, but they are useful in different situations. The last argument is simply the adapter class:: >>> registry.register([IFile], ISize, '', FileSize) You can now use the the registry to lookup the adapter:: >>> registry.lookup1(IFile, ISize, '') Let's get a little bit more practical. Let's create a `File` instance and create the adapter using a registry lookup. Then we see whether the adapter returns the correct size by calling `getSize()`:: >>> file = File() >>> size = registry.lookup1(IFile, ISize, '')(file) >>> size.getSize() 7 However, this is not very practical, since I have to manually pass in the arguments to the lookup method. There is some syntactic candy that will allow us to get an adapter instance by simply calling `ISize(file)`. To make use of this functionality, we need to add our registry to the adapter_hooks list, which is a member of the adapters module. This list stores a collection of callables that are automatically invoked when IFoo(obj) is called; their purpose is to locate adapters that implement an interface for a certain context instance. You are required to implement your own adapter hook; this example covers one of the simplest hooks that use the registry, but you could implement one that used an adapter cache or persistent adapters, for instance. The helper hook is required to expect as first argument the desired output interface (for us `ISize`) and as the second argument the context of the adapter (here `file`). The function returns an adapter, i.e. a `FileSize` instance:: >>> def hook(provided, object): ... adapter = registry.lookup1(zope.interface.providedBy(object), ... provided, '') ... return adapter(object) ... We now just add the hook to an `adapter_hooks` list:: >>> from zope.interface.interface import adapter_hooks >>> adapter_hooks.append(hook) Once the hook is registered, you can use the desired syntax:: >>> size = ISize(file) >>> size.getSize() 7 Now we have to cleanup after ourselves, so that others after us have a clean `adapter_hooks` list:: >>> adapter_hooks.remove(hook) That's it. I have intentionally left out a discussion of named adapters and multi-adapters, since this text is intended as a practical and simple introduction to Zope 3 interfaces and adapters. You might want to read the `adapter.txt` in the `zope.interface` package for a more formal, referencial and complete treatment of the package. Warning: People have reported that `adapter.txt` makes their brain feel soft! ``zope.interface Changelog`` ============================ 3.6.7 (2011-08-20) ------------------ - Fix sporadic failures on x86-64 platforms in tests of rich comparisons of interfaces. 3.6.6 (2011-08-13) ------------------ - LP #570942: Now correctly compare interfaces from different modules but with the same names. N.B.: This is a less intrusive / destabilizing fix than the one applied in 3.6.3: we only fix the underlying cmp-alike function, rather than adding the other "rich comparison" functions. - Revert to software as released with 3.6.1 for "stable" 3.6 release branch. 3.6.5 (2011-08-11) ------------------ - LP #811792: work around buggy behavior in some subclasses of ``zope.interface.interface.InterfaceClass``, which invoke ``__hash__`` before initializing ``__module__`` and ``__name__``. The workaround returns a fixed constant hash in such cases, and issues a ``UserWarning``. - LP #804832: Under PyPy, ``zope.interface`` should not build its C extension. Also, prevent attempting to build it under Jython. - Add a tox.ini for easier xplatform testing. - Fix testing deprecation warnings issued when tested under Py3K. 3.6.4 (2011-07-04) ------------------ - LP 804951: InterfaceClass instances were unhashable under Python 3.x. 3.6.3 (2011-05-26) ------------------ - LP #570942: Now correctly compare interfaces from different modules but with the same names. 3.6.2 (2011-05-17) ------------------ - Moved detailed documentation out-of-line from PyPI page, linking instead to http://docs.zope.org/zope.interface . - Fixes for small issues when running tests under Python 3.2 using ``zope.testrunner``. - LP # 675064: Specify return value type for C optimizations module init under Python 3: undeclared value caused warnings, and segfaults on some 64 bit architectures. - setup.py now raises RuntimeError if you don't have Distutils installed when running under Python 3. 3.6.1 (2010-05-03) ------------------ - A non-ASCII character in the changelog made 3.6.0 uninstallable on Python 3 systems with another default encoding than UTF-8. - Fixed compiler warnings under GCC 4.3.3. 3.6.0 (2010-04-29) ------------------ - LP #185974: Clear the cache used by ``Specificaton.get`` inside ``Specification.changed``. Thanks to Jacob Holm for the patch. - Added support for Python 3.1. Contributors: Lennart Regebro Martin v Loewis Thomas Lotze Wolfgang Schnerring The 3.1 support is completely backwards compatible. However, the implements syntax used under Python 2.X does not work under 3.X, since it depends on how metaclasses are implemented and this has changed. Instead it now supports a decorator syntax (also under Python 2.X):: class Foo: implements(IFoo) ... can now also be written:: @implementor(IFoo): class Foo: ... There are 2to3 fixers available to do this change automatically in the zope.fixers package. - Python 2.3 is no longer supported. 3.5.4 (2009-12-23) ------------------ - Use the standard Python doctest module instead of zope.testing.doctest, which has been deprecated. 3.5.3 (2009-12-08) ------------------ - Fix an edge case: make providedBy() work when a class has '__provides__' in its __slots__ (see http://thread.gmane.org/gmane.comp.web.zope.devel/22490) 3.5.2 (2009-07-01) ------------------ - BaseAdapterRegistry.unregister, unsubscribe: Remove empty portions of the data structures when something is removed. This avoids leaving references to global objects (interfaces) that may be slated for removal from the calling application. 3.5.1 (2009-03-18) ------------------ - verifyObject: use getattr instead of hasattr to test for object attributes in order to let exceptions other than AttributeError raised by properties propagate to the caller - Add Sphinx-based documentation building to the package buildout configuration. Use the ``bin/docs`` command after buildout. - Improve package description a bit. Unify changelog entries formatting. - Change package's mailing list address to zope-dev at zope.org as zope3-dev at zope.org is now retired. 3.5.0 (2008-10-26) ------------------ - Fixed declaration of _zope_interface_coptimizations, it's not a top level package. - Add a DocTestSuite for odd.py module, so their tests are run. - Allow to bootstrap on Jython. - Fix https://bugs.launchpad.net/zope3/3.3/+bug/98388: ISpecification was missing a declaration for __iro__. - Added optional code optimizations support, which allows the building of C code optimizations to fail (Jython). - Replaced `_flatten` with a non-recursive implementation, effectively making it 3x faster. 3.4.1 (2007-10-02) ------------------ - Fixed a setup bug that prevented installation from source on systems without setuptools. 3.4.0 (2007-07-19) ------------------ - Final release for 3.4.0. 3.4.0b3 (2007-05-22) -------------------- - Objects with picky custom comparison methods couldn't be added to component registries. Now, when checking whether an object is already registered, identity comparison is used. 3.3.0.1 (2007-01-03) -------------------- - Made a reference to OverflowWarning, which disappeared in Python 2.5, conditional. 3.3.0 (2007/01/03) ------------------ New Features ++++++++++++ - The adapter-lookup algorithim was refactored to make it much simpler and faster. Also, more of the adapter-lookup logic is implemented in C, making debugging of application code easier, since there is less infrastructre code to step through. - We now treat objects without interface declarations as if they declared that they provide zope.interface.Interface. - There are a number of richer new adapter-registration interfaces that provide greater control and introspection. - Added a new interface decorator to zope.interface that allows the setting of tagged values on an interface at definition time (see zope.interface.taggedValue). Bug Fixes +++++++++ - A bug in multi-adapter lookup sometimes caused incorrect adapters to be returned. 3.2.0.2 (2006-04-15) -------------------- - Fix packaging bug: 'package_dir' must be a *relative* path. 3.2.0.1 (2006-04-14) -------------------- - Packaging change: suppress inclusion of 'setup.cfg' in 'sdist' builds. 3.2.0 (2006-01-05) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope 3.2.0 release. 3.1.0 (2005-10-03) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope 3.1.0 release. - Made attribute resolution order consistent with component lookup order, i.e. new-style class MRO semantics. - Deprecated 'isImplementedBy' and 'isImplementedByInstancesOf' APIs in favor of 'implementedBy' and 'providedBy'. 3.0.1 (2005-07-27) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope X3.0.1 release. - Fixed a bug reported by James Knight, which caused adapter registries to fail occasionally to reflect declaration changes. 3.0.0 (2004-11-07) ------------------ - Corresponds to the verison of the zope.interface package shipped as part of the Zope X3.0.0 release.

Instead of describing the content of a page using a single template or static system of templates and METAL macros, content provider objects are dynamically looked up based on the setup/configuration of the application. .. contents:: Motivation and Design Goals --------------------------- Before diving into the features of this package let me take up a few bytes of text to explain the use cases that drove us to develop this package (also others) and how the API documented below fulfills/solves those use cases. When we started developing Zope 3, it was from a desire to decentralize functionality and thus the complexity of the Python code. And we were successful! The component architecture is a marvelous piece of software that hopefully will allow us to build scalable solutions for a very long time. However, when it comes to user interface design, in this case specifically HTML pages, we have failed to provide the features and patterns of assembeling a page from configured components. Looking up views for a particular content component and a request just simply does not work by itself. The content inside the page is still monolithic. One attempt to solve this problem are METAL macros, which allow you to insert other TAL snippets into your main template. But macros have two shortcomings. For one there is a "hard-coded" one-to-one mapping between a slot and the macro that fills that slot, which makes it impossible to register several macros for a given location. The second problem is that macros are not views in their own right; thus they cannot provide functionality that is independent of the main template's view. A second approach to modular UI design are rendering pipes. Rendering pipes have the great advantage that they can reach all regions of the page during every step of the rendering process. For example, if we have a widget in the middle of the page that requires some additional Javascript, then it is easy for a rendering unit to insert the Javascript file link in the HTML header of the page. This type of use case is very hard to solve using page templates. However, pipes are not the answer to componentized user interface, since they cannot simply deal with registering random content for a given page region. In fact, I propose that pipelines are orthogonal to content providers, the concept introducted below. A pipeline framework could easily use functionality provided by this and other packages to provide component-driven UI design. So our goal is clear: Bring the pluggability of the component architecture into page templates and user interface design. Zope is commonly known to reinvent the wheel, develop its own terminology and misuse other's terms. For example, the Plone community has a very different understanding of what a "portlet" is compared to the commonly accepted meaning in the corporate world, which derives its definition from JSR 168. Therefore an additional use case of the design of this package was to stick with common terms and use them in their original meaning -- well, given a little extra twist. The most basic user interface component in the Web application Java world is the "content provider" [1]_. A content provider is simply responsible for providing HTML content for a page. This is equivalent to a view that does not provide a full page, but just a snippet, much like widgets or macros. Once there is a way to configure those content providers, we need a way to insert them into our page templates. In our implementation this is accomplished using a new TALES namespace that allows to insert content providers by name. But how, you might wonder, does this provide a componentized user interface? On the Zope 3 level, each content provider is registered as a presentation component discriminated by the context, request and view it will appear in. Thus different content providers will be picked for different configurations. Okay, that's pretty much everything there is to say about content providers. What, we are done? Hold on, what about defining regions of pages and filling them configured UI snippets. The short answer is: See the ``zope.viewlet`` pacakge. But let me also give you the long answer. This and the other pacakges were developed using real world use cases. While doing this, we noticed that not every project would need, for example, all the features of a portlet, but would still profit from lower-level features. Thus we decided to declare clear boundaries of functionality and providing each level in a different package. This particualr package is only meant to provide the interface between the content provider world and page templates. .. [1] Note that this is a bit different from the role named content provider, which refers to a service that provides content; the content provider we are talking about here are the software components the service would provide to an application. Content Providers ----------------- Content Provider is a term from the Java world that refers to components that can provide HTML content. It means nothing more! How the content is found and returned is totally up to the implementation. The Zope 3 touch to the concept is that content providers are multi-adapters that are looked up by the context, request (and thus the layer/skin), and view they are displayed in. The second important concept of content providers are their two-phase rendering design. In the first phase the state of the content provider is prepared and, if applicable, any data the provider is responsible for is updated. >>> from zope.contentprovider import interfaces So let's create a simple content provider: >>> import zope.interface >>> import zope.component >>> from zope.publisher.interfaces import browser >>> class MessageBox(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... message = u'My Message' ... ... def __init__(self, context, request, view): ... self.__parent__ = view ... ... def update(self): ... pass ... ... def render(self): ... return u'
%s
' %self.message The ``update()`` method is executed during phase one. Since no state needs to be calculated and no data is modified by this simple content provider, it is an empty implementation. The ``render()`` method implements phase 2 of the process. We can now instantiate the content provider (manually) and render it: >>> box = MessageBox(None, None, None) >>> box.render() u'
My Message
' Since our content provider did not require the context, request or view to create its HTML content, we were able to pass trivial dummy values into the constructor. Also note that the provider must have a parent (using the ``__parent__`` attribute) specified at all times. The parent must be the view the provider appears in. I agree, this functionally does not seem very useful now. The constructor and the ``update()`` method seem useless and the returned content is totally static. However, we implemented a contract for content providers that other code can rely on. Content providers are (commonly) instantiated using the context, request and view they appear in and are required to always generate its HTML using those three components. Two-Phased Content Providers ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Let's now have a look at a content provider that actively uses the two-phase rendering process. The simpler scenario is the case where the content provider updates a content component without affecting anything else. So let's create a content component to be updated, >>> class Article(object): ... title = u'initial' >>> article = Article() and the content provider that is updating the title: >>> class ChangeTitle(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... fieldName = 'ChangeTitle.title' ... ... def __init__(self, context, request, view): ... self.__parent__ = view ... self.context, self.request = context, request ... ... def update(self): ... if self.fieldName in self.request: ... self.context.title = self.request[self.fieldName] ... ... def render(self): ... return u'' % (self.fieldName, ... self.context.title) Using a request, let's now instantiate the content provider and go through the two-phase rendering process: >>> from zope.publisher.browser import TestRequest >>> request = TestRequest() >>> changer = ChangeTitle(article, request, None) >>> changer.update() >>> changer.render() u'' Let's now enter a new title and render the provider: >>> request = TestRequest(form={'ChangeTitle.title': u'new title'}) >>> changer = ChangeTitle(article, request, None) >>> changer.update() >>> changer.render() u'' >>> article.title u'new title' So this was easy. Let's now look at a case where one content provider's update influences the content of another. Let's say we have a content provider that displays the article's title: >>> class ViewTitle(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... ... def __init__(self, context, request, view): ... self.context, self.__parent__ = context, view ... ... def update(self): ... pass ... ... def render(self): ... return u'

Title: %s

' % self.context.title Let's now say that the `ShowTitle` content provider is shown on a page *before* the `ChangeTitle` content provider. If we do the full rendering process for each provider in sequence, we get the wrong result: >>> request = TestRequest(form={'ChangeTitle.title': u'newer title'}) >>> viewer = ViewTitle(article, request, None) >>> viewer.update() >>> viewer.render() u'

Title: new title

' >>> changer = ChangeTitle(article, request, None) >>> changer.update() >>> changer.render() u'' So the correct way of doing this is to first complete phase 1 (update) for all providers, before executing phase 2 (render): >>> request = TestRequest(form={'ChangeTitle.title': u'newest title'}) >>> viewer = ViewTitle(article, request, None) >>> changer = ChangeTitle(article, request, None) >>> viewer.update() >>> changer.update() >>> viewer.render() u'

Title: newest title

' >>> changer.render() u'' ``UpdateNotCalled`` Errors ~~~~~~~~~~~~~~~~~~~~~~~~~~ Since calling ``update()`` before any other method that mutates the provider or any other data is so important to the correct functioning of the API, the developer has the choice to raise the ``UpdateNotCalled`` error, if any method is called before ``update()`` (with exception of the constructor): >>> class InfoBox(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... ... def __init__(self, context, request, view): ... self.__parent__ = view ... self.__updated = False ... ... def update(self): ... self.__updated = True ... ... def render(self): ... if not self.__updated: ... raise interfaces.UpdateNotCalled ... return u'
Some information
' >>> info = InfoBox(None, None, None) >>> info.render() Traceback (most recent call last): ... UpdateNotCalled: ``update()`` was not called yet. >>> info.update() >>> info.render() u'
Some information
' The TALES ``provider`` Expression --------------------------------- The ``provider`` expression will look up the name of the content provider, call it and return the HTML content. The first step, however, will be to register our content provider with the component architecture: >>> zope.component.provideAdapter(MessageBox, name='mypage.MessageBox') The content provider must be registered by name, since the TALES expression uses the name to look up the provider at run time. Let's now create a view using a page template: >>> import os, tempfile >>> temp_dir = tempfile.mkdtemp() >>> templateFileName = os.path.join(temp_dir, 'template.pt') >>> open(templateFileName, 'w').write(''' ... ... ...

My Web Page

...
... ...
...
... Content here ...
... ... ... ''') As you can see, we exprect the ``provider`` expression to simply look up the content provider and insert the HTML content at this place. Next we register the template as a view (browser page) for all objects: >>> from zope.browserpage.simpleviewclass import SimpleViewClass >>> FrontPage = SimpleViewClass(templateFileName, name='main.html') >>> zope.component.provideAdapter( ... FrontPage, ... (zope.interface.Interface, browser.IDefaultBrowserLayer), ... zope.interface.Interface, ... name='main.html') Let's create a content object that can be viewed: >>> class Content(object): ... zope.interface.implements(zope.interface.Interface) >>> content = Content() Finally we look up the view and render it. Note that a BeforeUpdateEvent is fired - this event should always be fired before any contentprovider is updated. >>> from zope.publisher.browser import TestRequest >>> events = [] >>> zope.component.provideHandler(events.append, (None, )) >>> request = TestRequest() >>> view = zope.component.getMultiAdapter((content, request), ... name='main.html') >>> print view().strip()

My Web Page

My Message
Content here
>>> events [] The event holds the provider and the request. >>> events[0].request >>> events[0].object Failure to lookup a Content Provider ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If the name is not found, an error is raised. To demonstrate this behavior let's create another template: >>> errorFileName = os.path.join(temp_dir, 'error.pt') >>> open(errorFileName, 'w').write(''' ... ... ... ... ... ... ''') >>> ErrorPage = SimpleViewClass(errorFileName, name='error.html') >>> zope.component.provideAdapter( ... ErrorPage, ... (zope.interface.Interface, browser.IDefaultBrowserLayer), ... zope.interface.Interface, ... name='main.html') >>> errorview = zope.component.getMultiAdapter((content, request), ... name='main.html') >>> print errorview() Traceback (most recent call last): ... ContentProviderLookupError: mypage.UnknownName Additional Data from TAL ~~~~~~~~~~~~~~~~~~~~~~~~ The ``provider`` expression allows also for transferring data from the TAL context into the content provider. This is accomplished by having the content provider implement an interface that specifies the attributes and provides ``ITALNamespaceData``: >>> import zope.schema >>> class IMessageText(zope.interface.Interface): ... message = zope.schema.Text(title=u'Text of the message box') >>> zope.interface.directlyProvides(IMessageText, ... interfaces.ITALNamespaceData) Now the message box can receive its text from the TAL environment: >>> class DynamicMessageBox(MessageBox): ... zope.interface.implements(IMessageText) >>> zope.component.provideAdapter( ... DynamicMessageBox, provides=interfaces.IContentProvider, ... name='mypage.DynamicMessageBox') We are now updating our original template to provide the message text: >>> open(templateFileName, 'w').write(''' ... ... ...

My Web Page

...
... ... ...
...
... Content here ...
... ... ... ''') Now we should get two message boxes with different text: >>> print view().strip()

My Web Page

Hello World!
Hello World again!
Content here
Finally, a content provider can also implement several ``ITALNamespaceData``: >>> class IMessageType(zope.interface.Interface): ... type = zope.schema.TextLine(title=u'The type of the message box') >>> zope.interface.directlyProvides(IMessageType, ... interfaces.ITALNamespaceData) We'll change our message box content provider implementation a bit, so the new information is used: >>> class BetterDynamicMessageBox(DynamicMessageBox): ... zope.interface.implements(IMessageType) ... type = None ... ... def render(self): ... return u'
%s
' %(self.type, self.message) >>> zope.component.provideAdapter( ... BetterDynamicMessageBox, provides=interfaces.IContentProvider, ... name='mypage.MessageBox') Of course, we also have to make our tempalte a little bit more dynamic as well: >>> open(templateFileName, 'w').write(''' ... ... ...

My Web Page

...
... ... ...
...
... Content here ...
... ... ... ''') Now we should get two message boxes with different text and types: >>> print view().strip()

Base class ---------- The ``zope.contentprovider.provider`` module provides an useful base class for implementing content providers. It has all boilerplate code and it's only required to override the ``render`` method to make it work: >>> from zope.contentprovider.provider import ContentProviderBase >>> class MyProvider(ContentProviderBase): ... def render(self, *args, **kwargs): ... return 'Hi there' >>> provider = MyProvider(None, None, None) >>> interfaces.IContentProvider.providedBy(provider) True >>> provider.update() >>> print provider.render() Hi there Note, that it can't be used as is, without providing the ``render`` method: >>> bad = ContentProviderBase(None, None, None) >>> bad.update() >>> print bad.render() Traceback (most recent call last): ... NotImplementedError: ``render`` method must be implemented by subclass You can add the update logic into the ``update`` method as with any content provider and you can implement more complex rendering patterns, based on templates, using this ContentProviderBase class as a base. You might also want to look at the ``zope.viewlet`` package for a more featureful API. Let's remove all temporary data we created during this README. >>> import shutil >>> shutil.rmtree(temp_dir) ======= CHANGES ======= 3.7.2 (2010-05-25) ------------------ - Fixed unit tests broken under Python 2.4 by the switch to the standard library ``doctest`` module. 3.7.1 (2010-04-30) ------------------ - Prefer the standard library's ``doctest`` module to the one from ``zope.testing.`` 3.7 (2010-04-27) ---------------- - Since ``tales:expressiontype`` is now in ``zope.browserpage``, update conditional ZCML accordingly so it doesn't depend on the presence of ``zope.app.pagetemplate`` anymore. 3.6.1 (2009-12-23) ------------------ - Ensure that our ``configure.zcml`` can be loaded without requiring further dependencies. It uses a ``tales:expressiontype`` directive defined in ``zope.app.pagetemplate.`` We keep that dependency optional, as not all consumers of this package use ZCML to configure the expression type. 3.6.0 (2009-12-22) ------------------ - Updated test dependency to use ``zope.browserpage``. 3.5.0 (2009-03-18) ------------------ - Add very simple, but useful base class for implementing content providers, see ``zope.contentprovider.provider.ContentProviderBase``. - Remove unneeded testing dependencies. We only need ``zope.testing`` and ``zope.app.pagetemplate``. - Remove zcml slug and old zpkg-related files. - Added setuptools dependency to setup.py. - Clean up package's description and documentation a bit. Remove duplicate text in README. - Change mailing list address to zope-dev at zope.org instead of retired one. - Change ``cheeseshop`` to ``pypi`` in the package url. 3.4.0 (2007-10-02) ------------------ - Initial release independent of the main Zope tree.

Instead of describing the content of a page using a single template or static system of templates and METAL macros, content provider objects are dynamically looked up based on the setup/configuration of the application. .. contents:: Motivation and Design Goals --------------------------- Before diving into the features of this package let me take up a few bytes of text to explain the use cases that drove us to develop this package (also others) and how the API documented below fulfills/solves those use cases. When we started developing Zope 3, it was from a desire to decentralize functionality and thus the complexity of the Python code. And we were successful! The component architecture is a marvelous piece of software that hopefully will allow us to build scalable solutions for a very long time. However, when it comes to user interface design, in this case specifically HTML pages, we have failed to provide the features and patterns of assembeling a page from configured components. Looking up views for a particular content component and a request just simply does not work by itself. The content inside the page is still monolithic. One attempt to solve this problem are METAL macros, which allow you to insert other TAL snippets into your main template. But macros have two shortcomings. For one there is a "hard-coded" one-to-one mapping between a slot and the macro that fills that slot, which makes it impossible to register several macros for a given location. The second problem is that macros are not views in their own right; thus they cannot provide functionality that is independent of the main template's view. A second approach to modular UI design are rendering pipes. Rendering pipes have the great advantage that they can reach all regions of the page during every step of the rendering process. For example, if we have a widget in the middle of the page that requires some additional Javascript, then it is easy for a rendering unit to insert the Javascript file link in the HTML header of the page. This type of use case is very hard to solve using page templates. However, pipes are not the answer to componentized user interface, since they cannot simply deal with registering random content for a given page region. In fact, I propose that pipelines are orthogonal to content providers, the concept introducted below. A pipeline framework could easily use functionality provided by this and other packages to provide component-driven UI design. So our goal is clear: Bring the pluggability of the component architecture into page templates and user interface design. Zope is commonly known to reinvent the wheel, develop its own terminology and misuse other's terms. For example, the Plone community has a very different understanding of what a "portlet" is compared to the commonly accepted meaning in the corporate world, which derives its definition from JSR 168. Therefore an additional use case of the design of this package was to stick with common terms and use them in their original meaning -- well, given a little extra twist. The most basic user interface component in the Web application Java world is the "content provider" [1]_. A content provider is simply responsible for providing HTML content for a page. This is equivalent to a view that does not provide a full page, but just a snippet, much like widgets or macros. Once there is a way to configure those content providers, we need a way to insert them into our page templates. In our implementation this is accomplished using a new TALES namespace that allows to insert content providers by name. But how, you might wonder, does this provide a componentized user interface? On the Zope 3 level, each content provider is registered as a presentation component discriminated by the context, request and view it will appear in. Thus different content providers will be picked for different configurations. Okay, that's pretty much everything there is to say about content providers. What, we are done? Hold on, what about defining regions of pages and filling them configured UI snippets. The short answer is: See the ``zope.viewlet`` pacakge. But let me also give you the long answer. This and the other pacakges were developed using real world use cases. While doing this, we noticed that not every project would need, for example, all the features of a portlet, but would still profit from lower-level features. Thus we decided to declare clear boundaries of functionality and providing each level in a different package. This particualr package is only meant to provide the interface between the content provider world and page templates. .. [1] Note that this is a bit different from the role named content provider, which refers to a service that provides content; the content provider we are talking about here are the software components the service would provide to an application. Content Providers ----------------- Content Provider is a term from the Java world that refers to components that can provide HTML content. It means nothing more! How the content is found and returned is totally up to the implementation. The Zope 3 touch to the concept is that content providers are multi-adapters that are looked up by the context, request (and thus the layer/skin), and view they are displayed in. The second important concept of content providers are their two-phase rendering design. In the first phase the state of the content provider is prepared and, if applicable, any data the provider is responsible for is updated. >>> from zope.contentprovider import interfaces So let's create a simple content provider: >>> import zope.interface >>> import zope.component >>> from zope.publisher.interfaces import browser >>> class MessageBox(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... message = u'My Message' ... ... def __init__(self, context, request, view): ... self.__parent__ = view ... ... def update(self): ... pass ... ... def render(self): ... return u'
%s
' %self.message The ``update()`` method is executed during phase one. Since no state needs to be calculated and no data is modified by this simple content provider, it is an empty implementation. The ``render()`` method implements phase 2 of the process. We can now instantiate the content provider (manually) and render it: >>> box = MessageBox(None, None, None) >>> box.render() u'
My Message
' Since our content provider did not require the context, request or view to create its HTML content, we were able to pass trivial dummy values into the constructor. Also note that the provider must have a parent (using the ``__parent__`` attribute) specified at all times. The parent must be the view the provider appears in. I agree, this functionally does not seem very useful now. The constructor and the ``update()`` method seem useless and the returned content is totally static. However, we implemented a contract for content providers that other code can rely on. Content providers are (commonly) instantiated using the context, request and view they appear in and are required to always generate its HTML using those three components. Two-Phased Content Providers ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Let's now have a look at a content provider that actively uses the two-phase rendering process. The simpler scenario is the case where the content provider updates a content component without affecting anything else. So let's create a content component to be updated, >>> class Article(object): ... title = u'initial' >>> article = Article() and the content provider that is updating the title: >>> class ChangeTitle(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... fieldName = 'ChangeTitle.title' ... ... def __init__(self, context, request, view): ... self.__parent__ = view ... self.context, self.request = context, request ... ... def update(self): ... if self.fieldName in self.request: ... self.context.title = self.request[self.fieldName] ... ... def render(self): ... return u'' % (self.fieldName, ... self.context.title) Using a request, let's now instantiate the content provider and go through the two-phase rendering process: >>> from zope.publisher.browser import TestRequest >>> request = TestRequest() >>> changer = ChangeTitle(article, request, None) >>> changer.update() >>> changer.render() u'' Let's now enter a new title and render the provider: >>> request = TestRequest(form={'ChangeTitle.title': u'new title'}) >>> changer = ChangeTitle(article, request, None) >>> changer.update() >>> changer.render() u'' >>> article.title u'new title' So this was easy. Let's now look at a case where one content provider's update influences the content of another. Let's say we have a content provider that displays the article's title: >>> class ViewTitle(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... ... def __init__(self, context, request, view): ... self.context, self.__parent__ = context, view ... ... def update(self): ... pass ... ... def render(self): ... return u'

Title: %s

' % self.context.title Let's now say that the `ShowTitle` content provider is shown on a page *before* the `ChangeTitle` content provider. If we do the full rendering process for each provider in sequence, we get the wrong result: >>> request = TestRequest(form={'ChangeTitle.title': u'newer title'}) >>> viewer = ViewTitle(article, request, None) >>> viewer.update() >>> viewer.render() u'

Title: new title

' >>> changer = ChangeTitle(article, request, None) >>> changer.update() >>> changer.render() u'' So the correct way of doing this is to first complete phase 1 (update) for all providers, before executing phase 2 (render): >>> request = TestRequest(form={'ChangeTitle.title': u'newest title'}) >>> viewer = ViewTitle(article, request, None) >>> changer = ChangeTitle(article, request, None) >>> viewer.update() >>> changer.update() >>> viewer.render() u'

Title: newest title

' >>> changer.render() u'' ``UpdateNotCalled`` Errors ~~~~~~~~~~~~~~~~~~~~~~~~~~ Since calling ``update()`` before any other method that mutates the provider or any other data is so important to the correct functioning of the API, the developer has the choice to raise the ``UpdateNotCalled`` error, if any method is called before ``update()`` (with exception of the constructor): >>> class InfoBox(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... ... def __init__(self, context, request, view): ... self.__parent__ = view ... self.__updated = False ... ... def update(self): ... self.__updated = True ... ... def render(self): ... if not self.__updated: ... raise interfaces.UpdateNotCalled ... return u'
Some information
' >>> info = InfoBox(None, None, None) >>> info.render() Traceback (most recent call last): ... UpdateNotCalled: ``update()`` was not called yet. >>> info.update() >>> info.render() u'
Some information
' The TALES ``provider`` Expression --------------------------------- The ``provider`` expression will look up the name of the content provider, call it and return the HTML content. The first step, however, will be to register our content provider with the component architecture: >>> zope.component.provideAdapter(MessageBox, name='mypage.MessageBox') The content provider must be registered by name, since the TALES expression uses the name to look up the provider at run time. Let's now create a view using a page template: >>> import os, tempfile >>> temp_dir = tempfile.mkdtemp() >>> templateFileName = os.path.join(temp_dir, 'template.pt') >>> open(templateFileName, 'w').write(''' ... ... ...

My Web Page

...
... ...
...
... Content here ...
... ... ... ''') As you can see, we exprect the ``provider`` expression to simply look up the content provider and insert the HTML content at this place. Next we register the template as a view (browser page) for all objects: >>> from zope.browserpage.simpleviewclass import SimpleViewClass >>> FrontPage = SimpleViewClass(templateFileName, name='main.html') >>> zope.component.provideAdapter( ... FrontPage, ... (zope.interface.Interface, browser.IDefaultBrowserLayer), ... zope.interface.Interface, ... name='main.html') Let's create a content object that can be viewed: >>> class Content(object): ... zope.interface.implements(zope.interface.Interface) >>> content = Content() Finally we look up the view and render it. Note that a BeforeUpdateEvent is fired - this event should always be fired before any contentprovider is updated. >>> from zope.publisher.browser import TestRequest >>> events = [] >>> zope.component.provideHandler(events.append, (None, )) >>> request = TestRequest() >>> view = zope.component.getMultiAdapter((content, request), ... name='main.html') >>> print view().strip()

My Web Page

My Message
Content here
>>> events [] The event holds the provider and the request. >>> events[0].request >>> events[0].object Failure to lookup a Content Provider ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If the name is not found, an error is raised. To demonstrate this behavior let's create another template: >>> errorFileName = os.path.join(temp_dir, 'error.pt') >>> open(errorFileName, 'w').write(''' ... ... ... ... ... ... ''') >>> ErrorPage = SimpleViewClass(errorFileName, name='error.html') >>> zope.component.provideAdapter( ... ErrorPage, ... (zope.interface.Interface, browser.IDefaultBrowserLayer), ... zope.interface.Interface, ... name='main.html') >>> errorview = zope.component.getMultiAdapter((content, request), ... name='main.html') >>> print errorview() Traceback (most recent call last): ... ContentProviderLookupError: mypage.UnknownName Additional Data from TAL ~~~~~~~~~~~~~~~~~~~~~~~~ The ``provider`` expression allows also for transferring data from the TAL context into the content provider. This is accomplished by having the content provider implement an interface that specifies the attributes and provides ``ITALNamespaceData``: >>> import zope.schema >>> class IMessageText(zope.interface.Interface): ... message = zope.schema.Text(title=u'Text of the message box') >>> zope.interface.directlyProvides(IMessageText, ... interfaces.ITALNamespaceData) Now the message box can receive its text from the TAL environment: >>> class DynamicMessageBox(MessageBox): ... zope.interface.implements(IMessageText) >>> zope.component.provideAdapter( ... DynamicMessageBox, provides=interfaces.IContentProvider, ... name='mypage.DynamicMessageBox') We are now updating our original template to provide the message text: >>> open(templateFileName, 'w').write(''' ... ... ...

My Web Page

...
... ... ...
...
... Content here ...
... ... ... ''') Now we should get two message boxes with different text: >>> print view().strip()

My Web Page

Hello World!
Hello World again!
Content here
Finally, a content provider can also implement several ``ITALNamespaceData``: >>> class IMessageType(zope.interface.Interface): ... type = zope.schema.TextLine(title=u'The type of the message box') >>> zope.interface.directlyProvides(IMessageType, ... interfaces.ITALNamespaceData) We'll change our message box content provider implementation a bit, so the new information is used: >>> class BetterDynamicMessageBox(DynamicMessageBox): ... zope.interface.implements(IMessageType) ... type = None ... ... def render(self): ... return u'
%s
' %(self.type, self.message) >>> zope.component.provideAdapter( ... BetterDynamicMessageBox, provides=interfaces.IContentProvider, ... name='mypage.MessageBox') Of course, we also have to make our tempalte a little bit more dynamic as well: >>> open(templateFileName, 'w').write(''' ... ... ...

My Web Page

...
... ... ...
...
... Content here ...
... ... ... ''') Now we should get two message boxes with different text and types: >>> print view().strip()

Instead of describing the content of a page using a single template or static system of templates and METAL macros, content provider objects are dynamically looked up based on the setup/configuration of the application. .. contents:: Motivation and Design Goals --------------------------- Before diving into the features of this package let me take up a few bytes of text to explain the use cases that drove us to develop this package (also others) and how the API documented below fulfills/solves those use cases. When we started developing Zope 3, it was from a desire to decentralize functionality and thus the complexity of the Python code. And we were successful! The component architecture is a marvelous piece of software that hopefully will allow us to build scalable solutions for a very long time. However, when it comes to user interface design, in this case specifically HTML pages, we have failed to provide the features and patterns of assembeling a page from configured components. Looking up views for a particular content component and a request just simply does not work by itself. The content inside the page is still monolithic. One attempt to solve this problem are METAL macros, which allow you to insert other TAL snippets into your main template. But macros have two shortcomings. For one there is a "hard-coded" one-to-one mapping between a slot and the macro that fills that slot, which makes it impossible to register several macros for a given location. The second problem is that macros are not views in their own right; thus they cannot provide functionality that is independent of the main template's view. A second approach to modular UI design are rendering pipes. Rendering pipes have the great advantage that they can reach all regions of the page during every step of the rendering process. For example, if we have a widget in the middle of the page that requires some additional Javascript, then it is easy for a rendering unit to insert the Javascript file link in the HTML header of the page. This type of use case is very hard to solve using page templates. However, pipes are not the answer to componentized user interface, since they cannot simply deal with registering random content for a given page region. In fact, I propose that pipelines are orthogonal to content providers, the concept introducted below. A pipeline framework could easily use functionality provided by this and other packages to provide component-driven UI design. So our goal is clear: Bring the pluggability of the component architecture into page templates and user interface design. Zope is commonly known to reinvent the wheel, develop its own terminology and misuse other's terms. For example, the Plone community has a very different understanding of what a "portlet" is compared to the commonly accepted meaning in the corporate world, which derives its definition from JSR 168. Therefore an additional use case of the design of this package was to stick with common terms and use them in their original meaning -- well, given a little extra twist. The most basic user interface component in the Web application Java world is the "content provider" [1]_. A content provider is simply responsible for providing HTML content for a page. This is equivalent to a view that does not provide a full page, but just a snippet, much like widgets or macros. Once there is a way to configure those content providers, we need a way to insert them into our page templates. In our implementation this is accomplished using a new TALES namespace that allows to insert content providers by name. But how, you might wonder, does this provide a componentized user interface? On the Zope 3 level, each content provider is registered as a presentation component discriminated by the context, request and view it will appear in. Thus different content providers will be picked for different configurations. Okay, that's pretty much everything there is to say about content providers. What, we are done? Hold on, what about defining regions of pages and filling them configured UI snippets. The short answer is: See the ``zope.viewlet`` pacakge. But let me also give you the long answer. This and the other pacakges were developed using real world use cases. While doing this, we noticed that not every project would need, for example, all the features of a portlet, but would still profit from lower-level features. Thus we decided to declare clear boundaries of functionality and providing each level in a different package. This particualr package is only meant to provide the interface between the content provider world and page templates. .. [1] Note that this is a bit different from the role named content provider, which refers to a service that provides content; the content provider we are talking about here are the software components the service would provide to an application. Content Providers ----------------- Content Provider is a term from the Java world that refers to components that can provide HTML content. It means nothing more! How the content is found and returned is totally up to the implementation. The Zope 3 touch to the concept is that content providers are multi-adapters that are looked up by the context, request (and thus the layer/skin), and view they are displayed in. The second important concept of content providers are their two-phase rendering design. In the first phase the state of the content provider is prepared and, if applicable, any data the provider is responsible for is updated. >>> from zope.contentprovider import interfaces So let's create a simple content provider: >>> import zope.interface >>> import zope.component >>> from zope.publisher.interfaces import browser >>> class MessageBox(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... message = u'My Message' ... ... def __init__(self, context, request, view): ... self.__parent__ = view ... ... def update(self): ... pass ... ... def render(self): ... return u'
%s
' %self.message The ``update()`` method is executed during phase one. Since no state needs to be calculated and no data is modified by this simple content provider, it is an empty implementation. The ``render()`` method implements phase 2 of the process. We can now instantiate the content provider (manually) and render it: >>> box = MessageBox(None, None, None) >>> box.render() u'
My Message
' Since our content provider did not require the context, request or view to create its HTML content, we were able to pass trivial dummy values into the constructor. Also note that the provider must have a parent (using the ``__parent__`` attribute) specified at all times. The parent must be the view the provider appears in. I agree, this functionally does not seem very useful now. The constructor and the ``update()`` method seem useless and the returned content is totally static. However, we implemented a contract for content providers that other code can rely on. Content providers are (commonly) instantiated using the context, request and view they appear in and are required to always generate its HTML using those three components. Two-Phased Content Providers ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Let's now have a look at a content provider that actively uses the two-phase rendering process. The simpler scenario is the case where the content provider updates a content component without affecting anything else. So let's create a content component to be updated, >>> class Article(object): ... title = u'initial' >>> article = Article() and the content provider that is updating the title: >>> class ChangeTitle(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... fieldName = 'ChangeTitle.title' ... ... def __init__(self, context, request, view): ... self.__parent__ = view ... self.context, self.request = context, request ... ... def update(self): ... if self.fieldName in self.request: ... self.context.title = self.request[self.fieldName] ... ... def render(self): ... return u'' % (self.fieldName, ... self.context.title) Using a request, let's now instantiate the content provider and go through the two-phase rendering process: >>> from zope.publisher.browser import TestRequest >>> request = TestRequest() >>> changer = ChangeTitle(article, request, None) >>> changer.update() >>> changer.render() u'' Let's now enter a new title and render the provider: >>> request = TestRequest(form={'ChangeTitle.title': u'new title'}) >>> changer = ChangeTitle(article, request, None) >>> changer.update() >>> changer.render() u'' >>> article.title u'new title' So this was easy. Let's now look at a case where one content provider's update influences the content of another. Let's say we have a content provider that displays the article's title: >>> class ViewTitle(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... ... def __init__(self, context, request, view): ... self.context, self.__parent__ = context, view ... ... def update(self): ... pass ... ... def render(self): ... return u'

Title: %s

' % self.context.title Let's now say that the `ShowTitle` content provider is shown on a page *before* the `ChangeTitle` content provider. If we do the full rendering process for each provider in sequence, we get the wrong result: >>> request = TestRequest(form={'ChangeTitle.title': u'newer title'}) >>> viewer = ViewTitle(article, request, None) >>> viewer.update() >>> viewer.render() u'

Title: new title

' >>> changer = ChangeTitle(article, request, None) >>> changer.update() >>> changer.render() u'' So the correct way of doing this is to first complete phase 1 (update) for all providers, before executing phase 2 (render): >>> request = TestRequest(form={'ChangeTitle.title': u'newest title'}) >>> viewer = ViewTitle(article, request, None) >>> changer = ChangeTitle(article, request, None) >>> viewer.update() >>> changer.update() >>> viewer.render() u'

Title: newest title

' >>> changer.render() u'' ``UpdateNotCalled`` Errors ~~~~~~~~~~~~~~~~~~~~~~~~~~ Since calling ``update()`` before any other method that mutates the provider or any other data is so important to the correct functioning of the API, the developer has the choice to raise the ``UpdateNotCalled`` error, if any method is called before ``update()`` (with exception of the constructor): >>> class InfoBox(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... ... def __init__(self, context, request, view): ... self.__parent__ = view ... self.__updated = False ... ... def update(self): ... self.__updated = True ... ... def render(self): ... if not self.__updated: ... raise interfaces.UpdateNotCalled ... return u'
Some information
' >>> info = InfoBox(None, None, None) >>> info.render() Traceback (most recent call last): ... UpdateNotCalled: ``update()`` was not called yet. >>> info.update() >>> info.render() u'
Some information
' The TALES ``provider`` Expression --------------------------------- The ``provider`` expression will look up the name of the content provider, call it and return the HTML content. The first step, however, will be to register our content provider with the component architecture: >>> zope.component.provideAdapter(MessageBox, name='mypage.MessageBox') The content provider must be registered by name, since the TALES expression uses the name to look up the provider at run time. Let's now create a view using a page template: >>> import os, tempfile >>> temp_dir = tempfile.mkdtemp() >>> templateFileName = os.path.join(temp_dir, 'template.pt') >>> open(templateFileName, 'w').write(''' ... ... ...

My Web Page

...
... ...
...
... Content here ...
... ... ... ''') As you can see, we exprect the ``provider`` expression to simply look up the content provider and insert the HTML content at this place. Next we register the template as a view (browser page) for all objects: >>> from zope.browserpage.simpleviewclass import SimpleViewClass >>> FrontPage = SimpleViewClass(templateFileName, name='main.html') >>> zope.component.provideAdapter( ... FrontPage, ... (zope.interface.Interface, browser.IDefaultBrowserLayer), ... zope.interface.Interface, ... name='main.html') Let's create a content object that can be viewed: >>> class Content(object): ... zope.interface.implements(zope.interface.Interface) >>> content = Content() Finally we look up the view and render it. Note that a BeforeUpdateEvent is fired - this event should always be fired before any contentprovider is updated. >>> from zope.publisher.browser import TestRequest >>> events = [] >>> zope.component.provideHandler(events.append, (None, )) >>> request = TestRequest() >>> view = zope.component.getMultiAdapter((content, request), ... name='main.html') >>> print view().strip()

My Web Page

My Message
Content here
>>> events [] The event holds the provider and the request. >>> events[0].request >>> events[0].object Failure to lookup a Content Provider ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If the name is not found, an error is raised. To demonstrate this behavior let's create another template: >>> errorFileName = os.path.join(temp_dir, 'error.pt') >>> open(errorFileName, 'w').write(''' ... ... ... ... ... ... ''') >>> ErrorPage = SimpleViewClass(errorFileName, name='error.html') >>> zope.component.provideAdapter( ... ErrorPage, ... (zope.interface.Interface, browser.IDefaultBrowserLayer), ... zope.interface.Interface, ... name='main.html') >>> errorview = zope.component.getMultiAdapter((content, request), ... name='main.html') >>> print errorview() Traceback (most recent call last): ... ContentProviderLookupError: mypage.UnknownName Additional Data from TAL ~~~~~~~~~~~~~~~~~~~~~~~~ The ``provider`` expression allows also for transferring data from the TAL context into the content provider. This is accomplished by having the content provider implement an interface that specifies the attributes and provides ``ITALNamespaceData``: >>> import zope.schema >>> class IMessageText(zope.interface.Interface): ... message = zope.schema.Text(title=u'Text of the message box') >>> zope.interface.directlyProvides(IMessageText, ... interfaces.ITALNamespaceData) Now the message box can receive its text from the TAL environment: >>> class DynamicMessageBox(MessageBox): ... zope.interface.implements(IMessageText) >>> zope.component.provideAdapter( ... DynamicMessageBox, provides=interfaces.IContentProvider, ... name='mypage.DynamicMessageBox') We are now updating our original template to provide the message text: >>> open(templateFileName, 'w').write(''' ... ... ...

My Web Page

...
... ... ...
...
... Content here ...
... ... ... ''') Now we should get two message boxes with different text: >>> print view().strip()

My Web Page

Hello World!
Hello World again!
Content here
Finally, a content provider can also implement several ``ITALNamespaceData``: >>> class IMessageType(zope.interface.Interface): ... type = zope.schema.TextLine(title=u'The type of the message box') >>> zope.interface.directlyProvides(IMessageType, ... interfaces.ITALNamespaceData) We'll change our message box content provider implementation a bit, so the new information is used: >>> class BetterDynamicMessageBox(DynamicMessageBox): ... zope.interface.implements(IMessageType) ... type = None ... ... def render(self): ... return u'
%s
' %(self.type, self.message) >>> zope.component.provideAdapter( ... BetterDynamicMessageBox, provides=interfaces.IContentProvider, ... name='mypage.MessageBox') Of course, we also have to make our tempalte a little bit more dynamic as well: >>> open(templateFileName, 'w').write(''' ... ... ...

My Web Page

...
... ... ...
...
... Content here ...
... ... ... ''') Now we should get two message boxes with different text and types: >>> print view().strip()

Base class ---------- The ``zope.contentprovider.provider`` module provides an useful base class for implementing content providers. It has all boilerplate code and it's only required to override the ``render`` method to make it work: >>> from zope.contentprovider.provider import ContentProviderBase >>> class MyProvider(ContentProviderBase): ... def render(self, *args, **kwargs): ... return 'Hi there' >>> provider = MyProvider(None, None, None) >>> interfaces.IContentProvider.providedBy(provider) True >>> provider.update() >>> print provider.render() Hi there Note, that it can't be used as is, without providing the ``render`` method: >>> bad = ContentProviderBase(None, None, None) >>> bad.update() >>> print bad.render() Traceback (most recent call last): ... NotImplementedError: ``render`` method must be implemented by subclass You can add the update logic into the ``update`` method as with any content provider and you can implement more complex rendering patterns, based on templates, using this ContentProviderBase class as a base. You might also want to look at the ``zope.viewlet`` package for a more featureful API.

Instead of describing the content of a page using a single template or static system of templates and METAL macros, content provider objects are dynamically looked up based on the setup/configuration of the application. .. contents:: Motivation and Design Goals --------------------------- Before diving into the features of this package let me take up a few bytes of text to explain the use cases that drove us to develop this package (also others) and how the API documented below fulfills/solves those use cases. When we started developing Zope 3, it was from a desire to decentralize functionality and thus the complexity of the Python code. And we were successful! The component architecture is a marvelous piece of software that hopefully will allow us to build scalable solutions for a very long time. However, when it comes to user interface design, in this case specifically HTML pages, we have failed to provide the features and patterns of assembeling a page from configured components. Looking up views for a particular content component and a request just simply does not work by itself. The content inside the page is still monolithic. One attempt to solve this problem are METAL macros, which allow you to insert other TAL snippets into your main template. But macros have two shortcomings. For one there is a "hard-coded" one-to-one mapping between a slot and the macro that fills that slot, which makes it impossible to register several macros for a given location. The second problem is that macros are not views in their own right; thus they cannot provide functionality that is independent of the main template's view. A second approach to modular UI design are rendering pipes. Rendering pipes have the great advantage that they can reach all regions of the page during every step of the rendering process. For example, if we have a widget in the middle of the page that requires some additional Javascript, then it is easy for a rendering unit to insert the Javascript file link in the HTML header of the page. This type of use case is very hard to solve using page templates. However, pipes are not the answer to componentized user interface, since they cannot simply deal with registering random content for a given page region. In fact, I propose that pipelines are orthogonal to content providers, the concept introducted below. A pipeline framework could easily use functionality provided by this and other packages to provide component-driven UI design. So our goal is clear: Bring the pluggability of the component architecture into page templates and user interface design. Zope is commonly known to reinvent the wheel, develop its own terminology and misuse other's terms. For example, the Plone community has a very different understanding of what a "portlet" is compared to the commonly accepted meaning in the corporate world, which derives its definition from JSR 168. Therefore an additional use case of the design of this package was to stick with common terms and use them in their original meaning -- well, given a little extra twist. The most basic user interface component in the Web application Java world is the "content provider" [1]_. A content provider is simply responsible for providing HTML content for a page. This is equivalent to a view that does not provide a full page, but just a snippet, much like widgets or macros. Once there is a way to configure those content providers, we need a way to insert them into our page templates. In our implementation this is accomplished using a new TALES namespace that allows to insert content providers by name. But how, you might wonder, does this provide a componentized user interface? On the Zope 3 level, each content provider is registered as a presentation component discriminated by the context, request and view it will appear in. Thus different content providers will be picked for different configurations. Okay, that's pretty much everything there is to say about content providers. What, we are done? Hold on, what about defining regions of pages and filling them configured UI snippets. The short answer is: See the ``zope.viewlet`` pacakge. But let me also give you the long answer. This and the other pacakges were developed using real world use cases. While doing this, we noticed that not every project would need, for example, all the features of a portlet, but would still profit from lower-level features. Thus we decided to declare clear boundaries of functionality and providing each level in a different package. This particualr package is only meant to provide the interface between the content provider world and page templates. .. [1] Note that this is a bit different from the role named content provider, which refers to a service that provides content; the content provider we are talking about here are the software components the service would provide to an application. Content Providers ----------------- Content Provider is a term from the Java world that refers to components that can provide HTML content. It means nothing more! How the content is found and returned is totally up to the implementation. The Zope 3 touch to the concept is that content providers are multi-adapters that are looked up by the context, request (and thus the layer/skin), and view they are displayed in. The second important concept of content providers are their two-phase rendering design. In the first phase the state of the content provider is prepared and, if applicable, any data the provider is responsible for is updated. >>> from zope.contentprovider import interfaces So let's create a simple content provider: >>> import zope.interface >>> import zope.component >>> from zope.publisher.interfaces import browser >>> class MessageBox(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... message = u'My Message' ... ... def __init__(self, context, request, view): ... self.__parent__ = view ... ... def update(self): ... pass ... ... def render(self): ... return u'
%s
' %self.message The ``update()`` method is executed during phase one. Since no state needs to be calculated and no data is modified by this simple content provider, it is an empty implementation. The ``render()`` method implements phase 2 of the process. We can now instantiate the content provider (manually) and render it: >>> box = MessageBox(None, None, None) >>> box.render() u'
My Message
' Since our content provider did not require the context, request or view to create its HTML content, we were able to pass trivial dummy values into the constructor. Also note that the provider must have a parent (using the ``__parent__`` attribute) specified at all times. The parent must be the view the provider appears in. I agree, this functionally does not seem very useful now. The constructor and the ``update()`` method seem useless and the returned content is totally static. However, we implemented a contract for content providers that other code can rely on. Content providers are (commonly) instantiated using the context, request and view they appear in and are required to always generate its HTML using those three components. Two-Phased Content Providers ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Let's now have a look at a content provider that actively uses the two-phase rendering process. The simpler scenario is the case where the content provider updates a content component without affecting anything else. So let's create a content component to be updated, >>> class Article(object): ... title = u'initial' >>> article = Article() and the content provider that is updating the title: >>> class ChangeTitle(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... fieldName = 'ChangeTitle.title' ... ... def __init__(self, context, request, view): ... self.__parent__ = view ... self.context, self.request = context, request ... ... def update(self): ... if self.fieldName in self.request: ... self.context.title = self.request[self.fieldName] ... ... def render(self): ... return u'' % (self.fieldName, ... self.context.title) Using a request, let's now instantiate the content provider and go through the two-phase rendering process: >>> from zope.publisher.browser import TestRequest >>> request = TestRequest() >>> changer = ChangeTitle(article, request, None) >>> changer.update() >>> changer.render() u'' Let's now enter a new title and render the provider: >>> request = TestRequest(form={'ChangeTitle.title': u'new title'}) >>> changer = ChangeTitle(article, request, None) >>> changer.update() >>> changer.render() u'' >>> article.title u'new title' So this was easy. Let's now look at a case where one content provider's update influences the content of another. Let's say we have a content provider that displays the article's title: >>> class ViewTitle(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... ... def __init__(self, context, request, view): ... self.context, self.__parent__ = context, view ... ... def update(self): ... pass ... ... def render(self): ... return u'

Title: %s

' % self.context.title Let's now say that the `ShowTitle` content provider is shown on a page *before* the `ChangeTitle` content provider. If we do the full rendering process for each provider in sequence, we get the wrong result: >>> request = TestRequest(form={'ChangeTitle.title': u'newer title'}) >>> viewer = ViewTitle(article, request, None) >>> viewer.update() >>> viewer.render() u'

Title: new title

' >>> changer = ChangeTitle(article, request, None) >>> changer.update() >>> changer.render() u'' So the correct way of doing this is to first complete phase 1 (update) for all providers, before executing phase 2 (render): >>> request = TestRequest(form={'ChangeTitle.title': u'newest title'}) >>> viewer = ViewTitle(article, request, None) >>> changer = ChangeTitle(article, request, None) >>> viewer.update() >>> changer.update() >>> viewer.render() u'

Title: newest title

' >>> changer.render() u'' ``UpdateNotCalled`` Errors ~~~~~~~~~~~~~~~~~~~~~~~~~~ Since calling ``update()`` before any other method that mutates the provider or any other data is so important to the correct functioning of the API, the developer has the choice to raise the ``UpdateNotCalled`` error, if any method is called before ``update()`` (with exception of the constructor): >>> class InfoBox(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... ... def __init__(self, context, request, view): ... self.__parent__ = view ... self.__updated = False ... ... def update(self): ... self.__updated = True ... ... def render(self): ... if not self.__updated: ... raise interfaces.UpdateNotCalled ... return u'
Some information
' >>> info = InfoBox(None, None, None) >>> info.render() Traceback (most recent call last): ... UpdateNotCalled: ``update()`` was not called yet. >>> info.update() >>> info.render() u'
Some information
' The TALES ``provider`` Expression --------------------------------- The ``provider`` expression will look up the name of the content provider, call it and return the HTML content. The first step, however, will be to register our content provider with the component architecture: >>> zope.component.provideAdapter(MessageBox, name='mypage.MessageBox') The content provider must be registered by name, since the TALES expression uses the name to look up the provider at run time. Let's now create a view using a page template: >>> import os, tempfile >>> temp_dir = tempfile.mkdtemp() >>> templateFileName = os.path.join(temp_dir, 'template.pt') >>> open(templateFileName, 'w').write(''' ... ... ...

My Web Page

...
... ...
...
... Content here ...
... ... ... ''') As you can see, we exprect the ``provider`` expression to simply look up the content provider and insert the HTML content at this place. Next we register the template as a view (browser page) for all objects: >>> from zope.browserpage.simpleviewclass import SimpleViewClass >>> FrontPage = SimpleViewClass(templateFileName, name='main.html') >>> zope.component.provideAdapter( ... FrontPage, ... (zope.interface.Interface, browser.IDefaultBrowserLayer), ... zope.interface.Interface, ... name='main.html') Let's create a content object that can be viewed: >>> class Content(object): ... zope.interface.implements(zope.interface.Interface) >>> content = Content() Finally we look up the view and render it. Note that a BeforeUpdateEvent is fired - this event should always be fired before any contentprovider is updated. >>> from zope.publisher.browser import TestRequest >>> events = [] >>> zope.component.provideHandler(events.append, (None, )) >>> request = TestRequest() >>> view = zope.component.getMultiAdapter((content, request), ... name='main.html') >>> print view().strip()

My Web Page

My Message
Content here
>>> events [] The event holds the provider and the request. >>> events[0].request >>> events[0].object Failure to lookup a Content Provider ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If the name is not found, an error is raised. To demonstrate this behavior let's create another template: >>> errorFileName = os.path.join(temp_dir, 'error.pt') >>> open(errorFileName, 'w').write(''' ... ... ... ... ... ... ''') >>> ErrorPage = SimpleViewClass(errorFileName, name='error.html') >>> zope.component.provideAdapter( ... ErrorPage, ... (zope.interface.Interface, browser.IDefaultBrowserLayer), ... zope.interface.Interface, ... name='main.html') >>> errorview = zope.component.getMultiAdapter((content, request), ... name='main.html') >>> print errorview() Traceback (most recent call last): ... ContentProviderLookupError: mypage.UnknownName Additional Data from TAL ~~~~~~~~~~~~~~~~~~~~~~~~ The ``provider`` expression allows also for transferring data from the TAL context into the content provider. This is accomplished by having the content provider implement an interface that specifies the attributes and provides ``ITALNamespaceData``: >>> import zope.schema >>> class IMessageText(zope.interface.Interface): ... message = zope.schema.Text(title=u'Text of the message box') >>> zope.interface.directlyProvides(IMessageText, ... interfaces.ITALNamespaceData) Now the message box can receive its text from the TAL environment: >>> class DynamicMessageBox(MessageBox): ... zope.interface.implements(IMessageText) >>> zope.component.provideAdapter( ... DynamicMessageBox, provides=interfaces.IContentProvider, ... name='mypage.DynamicMessageBox') We are now updating our original template to provide the message text: >>> open(templateFileName, 'w').write(''' ... ... ...

My Web Page

...
... ... ...
...
... Content here ...
... ... ... ''') Now we should get two message boxes with different text: >>> print view().strip()

My Web Page

Hello World!
Hello World again!
Content here
Finally, a content provider can also implement several ``ITALNamespaceData``: >>> class IMessageType(zope.interface.Interface): ... type = zope.schema.TextLine(title=u'The type of the message box') >>> zope.interface.directlyProvides(IMessageType, ... interfaces.ITALNamespaceData) We'll change our message box content provider implementation a bit, so the new information is used: >>> class BetterDynamicMessageBox(DynamicMessageBox): ... zope.interface.implements(IMessageType) ... type = None ... ... def render(self): ... return u'
%s
' %(self.type, self.message) >>> zope.component.provideAdapter( ... BetterDynamicMessageBox, provides=interfaces.IContentProvider, ... name='mypage.MessageBox') Of course, we also have to make our tempalte a little bit more dynamic as well: >>> open(templateFileName, 'w').write(''' ... ... ...

My Web Page

...
... ... ...
...
... Content here ...
... ... ... ''') Now we should get two message boxes with different text and types: >>> print view().strip()

It has all boilerplate code and it's only required to override the ``render`` method to make it work: >>> from zope.contentprovider.provider import ContentProviderBase >>> class MyProvider(ContentProviderBase): ... def render(self, *args, **kwargs): ... return 'Hi there' >>> provider = MyProvider(None, None, None) >>> interfaces.IContentProvider.providedBy(provider) True >>> provider.update() >>> print provider.render() Hi there Note, that it can't be used as is, without providing the ``render`` method: >>> bad = ContentProviderBase(None, None, None) >>> bad.update() >>> print bad.render() Traceback (most recent call last): ... NotImplementedError: ``render`` method must be implemented by subclass You can add the update logic into the ``update`` method as with any content provider and you can implement more complex rendering patterns, based on templates, using this ContentProviderBase class as a base. You might also want to look at the ``zope.viewlet`` package for a more featureful API. Let's remove all temporary data we created during this README. >>> import shutil >>> shutil.rmtree(temp_dir) zope2.13-2.13.21/source/zope.contentprovider/src/zope/contentprovider/tests.py0000644000175000017500000000344012214017551026344 0ustar arnauarnau############################################################################## # # Copyright (c) 2004 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

Home-page: http://pypi.python.org/pypi/Products.MailHost Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: Overview ======== The MailHost product provides support for sending email from within the Zope environment using MailHost objects. An optional character set can be specified to automatically encode unicode input, and perform appropriate RFC 2822 header and body encoding for the specified character set. Full python email.Message.Message objects may be sent. Email can optionally be encoded using Base64, Quoted-Printable or UUEncode encoding (though automatic body encoding will be applied if a character set is specified). MailHost provides integration with the Zope transaction system and optional support for asynchronous mail delivery. Asynchronous mail delivery is implemented using a queue and a dedicated thread processing the queue. The thread is (re)-started automatically when sending an email. The thread can be started manually (in case of restart) by calling its manage_restartQueueThread?action=start method through HTTP. There is currently no possibility to start the thread at Zope startup time. Supports TLS/SSL encryption (requires Python compiled with SSL support).

An optional character set can be specified to automatically encode unicode input, and perform appropriate RFC 2822 header and body encoding for the specified character set. Full python email.Message.Message objects may be sent. Email can optionally be encoded using Base64, Quoted-Printable or UUEncode encoding (though automatic body encoding will be applied if a character set is specified). MailHost provides integration with the Zope transaction system and optional support for asynchronous mail delivery. Asynchronous mail delivery is implemented using a queue and a dedicated thread processing the queue. The thread is (re)-started automatically when sending an email. The thread can be started manually (in case of restart) by calling its manage_restartQueueThread?action=start method through HTTP. There is currently no possibility to start the thread at Zope startup time.

It is used in Zope, but it's not Zope specific at all. For instance, it can be used to test or otherwise interact with any web site. ====================== Detailed Documentation ====================== Different Browsers ------------------ HTTP Browser ~~~~~~~~~~~~ The ``zope.testbrowser.browser`` module exposes a ``Browser`` class that simulates a web browser similar to Mozilla Firefox or IE. >>> from zope.testbrowser.browser import Browser >>> browser = Browser() This version of the browser object can be used to access any web site just as you would do using a normal web browser. WSGI Test Browser ~~~~~~~~~~~~~~~~~ There is also a special version of the ``Browser`` class which uses `wsgi_intercept`_ and can be used to do functional testing of WSGI applications, it can be imported from ``zope.testbrowser.wsgi``: >>> from zope.testbrowser.wsgi import Browser >>> browser = Browser() .. _`wsgi_intercept`: http://pypi.python.org/pypi/wsgi_intercept To use this browser you have to: * use the `wsgi` extra of the ``zope.testbrowser`` egg, * write a subclass of ``zope.testbrowser.wsgi.Layer`` and override the ``make_wsgi_app`` method, * use an instance of the class as the test layer of your test. Example: >>> import zope.testbrowser.wsgi >>> class SimpleLayer(zope.testbrowser.wsgi.Layer): ... def make_wsgi_app(self): ... return simple_app Where ``simple_app`` is the callable of your WSGI application. Zope 3 Test Browser ~~~~~~~~~~~~~~~~~~~ There is also a special version of the ``Browser`` class used to do functional testing of Zope 3 applications, it can be imported from ``zope.testbrowser.testing``: >>> from zope.testbrowser.testing import Browser >>> browser = Browser() Bowser Usage ------------ All browsers are used the same way. An initial page to load can be passed to the ``Browser`` constructor: >>> browser = Browser('http://localhost/@@/testbrowser/simple.html') >>> browser.url 'http://localhost/@@/testbrowser/simple.html' The browser can send arbitrary headers; this is helpful for setting the "Authorization" header or a language value, so that your tests format values the way you expect in your tests, if you rely on zope.i18n locale-based formatting or a similar approach. >>> browser.addHeader('Authorization', 'Basic mgr:mgrpw') >>> browser.addHeader('Accept-Language', 'en-US') An existing browser instance can also `open` web pages: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.url 'http://localhost/@@/testbrowser/simple.html' Once you have opened a web page initially, best practice for writing testbrowser doctests suggests using 'click' to navigate further (as discussed below), except in unusual circumstances. The test browser complies with the IBrowser interface; see ``zope.testbrowser.interfaces`` for full details on the interface. >>> from zope.testbrowser import interfaces >>> from zope.interface.verify import verifyObject >>> verifyObject(interfaces.IBrowser, browser) True Page Contents ------------- The contents of the current page are available: >>> print browser.contents Simple Page

Simple Page

Making assertions about page contents is easy. >>> '

Simple Page

' in browser.contents True Utilizing the doctest facilities, it also possible to do: >>> browser.contents '...

Simple Page

...' Note: Unfortunately, ellipsis (...) cannot be used at the beginning of the output (this is a limitation of doctest). Checking for HTML ----------------- Not all URLs return HTML. Of course our simple page does: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.isHtml True But if we load an image (or other binary file), we do not get HTML: >>> browser.open('http://localhost/@@/testbrowser/zope3logo.gif') >>> browser.isHtml False HTML Page Title ---------------- Another useful helper property is the title: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.title 'Simple Page' If a page does not provide a title, it is simply ``None``: >>> browser.open('http://localhost/@@/testbrowser/notitle.html') >>> browser.title However, if the output is not HTML, then an error will occur trying to access the title: >>> browser.open('http://localhost/@@/testbrowser/zope3logo.gif') >>> browser.title Traceback (most recent call last): ... BrowserStateError: not viewing HTML Headers ------- As you can see, the `contents` of the browser does not return any HTTP headers. The headers are accessible via a separate attribute, which is an ``httplib.HTTPMessage`` instance (httplib is a part of Python's standard library): >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.headers The headers can be accessed as a string: >>> print browser.headers Status: 200 OK Content-Length: 123 Content-Type: text/html;charset=utf-8 X-Powered-By: Zope (www.zope.org), Python (www.python.org) Or as a mapping: >>> browser.headers['content-type'] 'text/html;charset=utf-8' Cookies ------- When a Set-Cookie header is available, it can be found in the headers, as seen above. Here, we use a view that will make the server set cookies with the values we provide. >>> browser.open('http://localhost/set_cookie.html?name=foo&value=bar') >>> browser.headers['set-cookie'].replace(';', '') 'foo=bar' It is also available in the browser's ``cookies`` attribute. This is an extended mapping interface that allows getting, setting, and deleting the cookies that the browser is remembering *for the current url*. Here are a few examples. >>> browser.cookies['foo'] 'bar' >>> browser.cookies.keys() ['foo'] >>> browser.cookies.values() ['bar'] >>> browser.cookies.items() [('foo', 'bar')] >>> 'foo' in browser.cookies True >>> 'bar' in browser.cookies False >>> len(browser.cookies) 1 >>> print(dict(browser.cookies)) {'foo': 'bar'} >>> browser.cookies['sha'] = 'zam' >>> len(browser.cookies) 2 >>> sorted(browser.cookies.items()) [('foo', 'bar'), ('sha', 'zam')] >>> browser.open('http://localhost/get_cookie.html') >>> print browser.headers.get('set-cookie') None >>> print browser.contents # server got the cookie change foo: bar sha: zam >>> sorted(browser.cookies.items()) [('foo', 'bar'), ('sha', 'zam')] >>> browser.cookies.clearAll() >>> len(browser.cookies) 0 Many more examples, and a discussion of the additional methods available, can be found in cookies.txt. Navigation and Link Objects --------------------------- If you want to simulate clicking on a link, get the link and `click` on it. In the `navigate.html` file there are several links set up to demonstrate the capabilities of the link objects and their `click` method. The simplest way to get a link is via the anchor text. In other words the text you would see in a browser (text and url searches are substring searches): >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...Link Text...' >>> link = browser.getLink('Link Text') >>> link Link objects comply with the ILink interface. >>> verifyObject(interfaces.ILink, link) True Links expose several attributes for easy access. >>> link.text 'Link Text' >>> link.tag # links can also be image maps. 'a' >>> link.url # it's normalized 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text' >>> link.attrs {'href': 'navigate.html?message=By+Link+Text'} Links can be "clicked" and the browser will navigate to the referenced URL. >>> link.click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text' >>> browser.contents '...Message: By Link Text...' When finding a link by its text, whitespace is normalized. >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...> Link Text \n with Whitespace\tNormalization (and parens) >> link = browser.getLink('Link Text with Whitespace Normalization ' ... '(and parens)') >>> link >>> link.text 'Link Text with Whitespace Normalization (and parens)' >>> link.click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text+with+Normalization' >>> browser.contents '...Message: By Link Text with Normalization...' When a link text matches more than one link, by default the first one is chosen. You can, however, specify the index of the link and thus retrieve a later matching link: >>> browser.getLink('Link Text') >>> browser.getLink('Link Text', index=1) Note that clicking a link object after its browser page has expired will generate an error. >>> link.click() Traceback (most recent call last): ... ExpiredError You can also find the link by its URL, >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...Using the URL...' >>> browser.getLink(url='?message=By+URL').click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+URL' >>> browser.contents '...Message: By URL...' or its id: >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...By Anchor Id...' >>> browser.getLink(id='anchorid').click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Id' >>> browser.contents '...Message: By Id...' You thought we were done here? Not so quickly. The `getLink` method also supports image maps, though not by specifying the coordinates, but using the area's id: >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> link = browser.getLink(id='zope3') >>> link.tag 'area' >>> link.click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=Zope+3+Name' >>> browser.contents '...Message: Zope 3 Name...' Getting a nonexistent link raises an exception. >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.getLink('This does not exist') Traceback (most recent call last): ... LinkNotFoundError A convenience method is provided to follow links; this uses the same arguments as `getLink`, but clicks on the link instead of returning the link object. >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...Link Text...' >>> browser.follow('Link Text') >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text' >>> browser.contents '...Message: By Link Text...' >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.follow(url='?message=By+URL') >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+URL' >>> browser.contents '...Message: By URL...' >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.follow(id='zope3') >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=Zope+3+Name' >>> browser.contents '...Message: Zope 3 Name...' Attempting to follow links that don't exist raises the same exception as asking for the link object: >>> browser.follow('This does not exist') Traceback (most recent call last): ... LinkNotFoundError Other Navigation ---------------- Like in any normal browser, you can reload a page: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.url 'http://localhost/@@/testbrowser/simple.html' >>> browser.reload() >>> browser.url 'http://localhost/@@/testbrowser/simple.html' You can also go back: >>> browser.open('http://localhost/@@/testbrowser/notitle.html') >>> browser.url 'http://localhost/@@/testbrowser/notitle.html' >>> browser.goBack() >>> browser.url 'http://localhost/@@/testbrowser/simple.html' Controls -------- One of the most important features of the browser is the ability to inspect and fill in values for the controls of input forms. To do so, let's first open a page that has a bunch of controls: >>> browser.open('http://localhost/@@/testbrowser/controls.html') Obtaining a Control ~~~~~~~~~~~~~~~~~~~ You look up browser controls with the 'getControl' method. The default first argument is 'label', and looks up the form on the basis of any associated label. >>> control = browser.getControl('Text Control') >>> control >>> browser.getControl(label='Text Control') # equivalent If you request a control that doesn't exist, the code raises a LookupError: >>> browser.getControl('Does Not Exist') Traceback (most recent call last): ... LookupError: label 'Does Not Exist' If you request a control with an ambiguous lookup, the code raises an AmbiguityError. >>> browser.getControl('Ambiguous Control') Traceback (most recent call last): ... AmbiguityError: label 'Ambiguous Control' This is also true if an option in a control is ambiguous in relation to the control itself. >>> browser.getControl('Sub-control Ambiguity') Traceback (most recent call last): ... AmbiguityError: label 'Sub-control Ambiguity' Ambiguous controls may be specified using an index value. We use the control's value attribute to show the two controls; this attribute is properly introduced below. >>> browser.getControl('Ambiguous Control', index=0) >>> browser.getControl('Ambiguous Control', index=0).value 'First' >>> browser.getControl('Ambiguous Control', index=1).value 'Second' >>> browser.getControl('Sub-control Ambiguity', index=0) >>> browser.getControl('Sub-control Ambiguity', index=1).optionValue 'ambiguous' Label searches are against stripped, whitespace-normalized, no-tag versions of the text. Text applied to searches is also stripped and whitespace normalized. The search finds results if the text search finds the whole words of your text in a label. Thus, for instance, a search for 'Add' will match the label 'Add a Client' but not 'Address'. Case is honored. >>> browser.getControl('Label Needs Whitespace Normalization') >>> browser.getControl('label needs whitespace normalization') Traceback (most recent call last): ... LookupError: label 'label needs whitespace normalization' >>> browser.getControl(' Label Needs Whitespace ') >>> browser.getControl('Whitespace') >>> browser.getControl('hitespace') Traceback (most recent call last): ... LookupError: label 'hitespace' >>> browser.getControl('[non word characters should not confuse]') Multiple labels can refer to the same control (simply because that is possible in the HTML 4.0 spec). >>> browser.getControl('Multiple labels really') >>> browser.getControl('really are possible') >>> browser.getControl('really') # OK: ambiguous labels, but not ambiguous control A label can be connected with a control using the 'for' attribute and also by containing a control. >>> browser.getControl( ... 'Labels can be connected by containing their respective fields') Get also accepts one other search argument, 'name'. Only one of 'label' and 'name' may be used at a time. The 'name' keyword searches form field names. >>> browser.getControl(name='text-value') >>> browser.getControl(name='ambiguous-control-name') Traceback (most recent call last): ... AmbiguityError: name 'ambiguous-control-name' >>> browser.getControl(name='does-not-exist') Traceback (most recent call last): ... LookupError: name 'does-not-exist' >>> browser.getControl(name='ambiguous-control-name', index=1).value 'Second' Combining 'label' and 'name' raises a ValueError, as does supplying neither of them. >>> browser.getControl(label='Ambiguous Control', name='ambiguous-control-name') Traceback (most recent call last): ... ValueError: Supply one and only one of "label" and "name" as arguments >>> browser.getControl() Traceback (most recent call last): ... ValueError: Supply one and only one of "label" and "name" as arguments Radio and checkbox fields are unusual in that their labels and names may point to different objects: names point to logical collections of radio buttons or checkboxes, but labels may only be used for individual choices within the logical collection. This means that obtaining a radio button by label gets a different object than obtaining the radio collection by name. Select options may also be searched by label. >>> browser.getControl(name='radio-value') >>> browser.getControl('Zwei') >>> browser.getControl('One') >>> browser.getControl('Tres') Characteristics of controls and subcontrols are discussed below. Control Objects ~~~~~~~~~~~~~~~ Controls provide IControl. >>> ctrl = browser.getControl('Text Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True They have several useful attributes: - the name as which the control is known to the form: >>> ctrl.name 'text-value' - the value of the control, which may also be set: >>> ctrl.value 'Some Text' >>> ctrl.value = 'More Text' >>> ctrl.value 'More Text' - the type of the control: >>> ctrl.type 'text' - a flag describing whether the control is disabled: >>> ctrl.disabled False - and a flag to tell us whether the control can have multiple values: >>> ctrl.multiple False Additionally, controllers for select, radio, and checkbox provide IListControl. These fields have four other attributes and an additional method: >>> ctrl = browser.getControl('Multiple Select Control') >>> ctrl >>> ctrl.disabled False >>> ctrl.multiple True >>> verifyObject(interfaces.IListControl, ctrl) True - 'options' lists all available value options. >>> ctrl.options ['1', '2', '3'] - 'displayOptions' lists all available options by label. The 'label' attribute on an option has precedence over its contents, which is why our last option is 'Third' in the display. >>> ctrl.displayOptions ['Un', 'Deux', 'Third'] - 'displayValue' lets you get and set the displayed values of the control of the select box, rather than the actual values. >>> ctrl.value [] >>> ctrl.displayValue [] >>> ctrl.displayValue = ['Un', 'Deux'] >>> ctrl.displayValue ['Un', 'Deux'] >>> ctrl.value ['1', '2'] - 'controls' gives you a list of the subcontrol objects in the control (subcontrols are discussed below). >>> ctrl.controls [, , ] - The 'getControl' method lets you get subcontrols by their label or their value. >>> ctrl.getControl('Un') >>> ctrl.getControl('Deux') >>> ctrl.getControl('Trois') # label attribute >>> ctrl.getControl('Third') # contents >>> browser.getControl('Third') # ambiguous in the browser, so useful Traceback (most recent call last): ... AmbiguityError: label 'Third' Finally, submit controls provide ISubmitControl, and image controls provide IImageSubmitControl, which extents ISubmitControl. These both simply add a 'click' method. For image submit controls, you may also provide a coordinates argument, which is a tuple of (x, y). These submit the forms, and are demonstrated below as we examine each control individually. ItemControl Objects ~~~~~~~~~~~~~~~~~~~ As introduced briefly above, using labels to obtain elements of a logical radio button or checkbox collection returns item controls, which are parents. Manipulating the value of these controls affects the parent control. >>> browser.getControl(name='radio-value').value ['2'] >>> browser.getControl('Zwei').optionValue # read-only. '2' >>> browser.getControl('Zwei').selected True >>> verifyObject(interfaces.IItemControl, browser.getControl('Zwei')) True >>> browser.getControl('Ein').selected = True >>> browser.getControl('Ein').selected True >>> browser.getControl('Zwei').selected False >>> browser.getControl(name='radio-value').value ['1'] >>> browser.getControl('Ein').selected = False >>> browser.getControl(name='radio-value').value [] >>> browser.getControl('Zwei').selected = True Checkbox collections behave similarly, as shown below. Controls with subcontrols-- Various Controls ~~~~~~~~~~~~~~~~ The various types of controls are demonstrated here. - Text Control The text control we already introduced above. - Password Control >>> ctrl = browser.getControl('Password Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value 'Password' >>> ctrl.value = 'pass now' >>> ctrl.value 'pass now' >>> ctrl.disabled False >>> ctrl.multiple False - Hidden Control >>> ctrl = browser.getControl(name='hidden-value') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value 'Hidden' >>> ctrl.value = 'More Hidden' >>> ctrl.disabled False >>> ctrl.multiple False - Text Area Control >>> ctrl = browser.getControl('Text Area Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value ' Text inside\n area!\n ' >>> ctrl.value = 'A lot of\n text.' >>> ctrl.disabled False >>> ctrl.multiple False - File Control File controls are used when a form has a file-upload field. To specify data, call the add_file method, passing: - A file-like object - a content type, and - a file name >>> ctrl = browser.getControl('File Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value is None True >>> import cStringIO >>> ctrl.add_file(cStringIO.StringIO('File contents'), ... 'text/plain', 'test.txt') The file control (like the other controls) also knows if it is disabled or if it can have multiple values. >>> ctrl.disabled False >>> ctrl.multiple False - Selection Control (Single-Valued) >>> ctrl = browser.getControl('Single Select Control') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value ['1'] >>> ctrl.value = ['2'] >>> ctrl.disabled False >>> ctrl.multiple False >>> ctrl.options ['1', '2', '3'] >>> ctrl.displayOptions ['Uno', 'Dos', 'Third'] >>> ctrl.displayValue ['Dos'] >>> ctrl.displayValue = ['Tres'] >>> ctrl.displayValue ['Third'] >>> ctrl.displayValue = ['Dos'] >>> ctrl.displayValue ['Dos'] >>> ctrl.displayValue = ['Third'] >>> ctrl.displayValue ['Third'] >>> ctrl.value ['3'] - Selection Control (Multi-Valued) This was already demonstrated in the introduction to control objects above. - Checkbox Control (Single-Valued; Unvalued) >>> ctrl = browser.getControl(name='single-unvalued-checkbox-value') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value True >>> ctrl.value = False >>> ctrl.disabled False >>> ctrl.multiple True >>> ctrl.options [True] >>> ctrl.displayOptions ['Single Unvalued Checkbox'] >>> ctrl.displayValue [] >>> verifyObject( ... interfaces.IItemControl, ... browser.getControl('Single Unvalued Checkbox')) True >>> browser.getControl('Single Unvalued Checkbox').optionValue 'on' >>> browser.getControl('Single Unvalued Checkbox').selected False >>> ctrl.displayValue = ['Single Unvalued Checkbox'] >>> ctrl.displayValue ['Single Unvalued Checkbox'] >>> browser.getControl('Single Unvalued Checkbox').selected True >>> browser.getControl('Single Unvalued Checkbox').selected = False >>> browser.getControl('Single Unvalued Checkbox').selected False >>> ctrl.displayValue [] >>> browser.getControl( ... name='single-disabled-unvalued-checkbox-value').disabled True - Checkbox Control (Single-Valued, Valued) >>> ctrl = browser.getControl(name='single-valued-checkbox-value') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value ['1'] >>> ctrl.value = [] >>> ctrl.disabled False >>> ctrl.multiple True >>> ctrl.options ['1'] >>> ctrl.displayOptions ['Single Valued Checkbox'] >>> ctrl.displayValue [] >>> verifyObject( ... interfaces.IItemControl, ... browser.getControl('Single Valued Checkbox')) True >>> browser.getControl('Single Valued Checkbox').selected False >>> browser.getControl('Single Valued Checkbox').optionValue '1' >>> ctrl.displayValue = ['Single Valued Checkbox'] >>> ctrl.displayValue ['Single Valued Checkbox'] >>> browser.getControl('Single Valued Checkbox').selected True >>> browser.getControl('Single Valued Checkbox').selected = False >>> browser.getControl('Single Valued Checkbox').selected False >>> ctrl.displayValue [] - Checkbox Control (Multi-Valued) >>> ctrl = browser.getControl(name='multi-checkbox-value') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value ['1', '3'] >>> ctrl.value = ['1', '2'] >>> ctrl.disabled False >>> ctrl.multiple True >>> ctrl.options ['1', '2', '3'] >>> ctrl.displayOptions ['One', 'Two', 'Three'] >>> ctrl.displayValue ['One', 'Two'] >>> ctrl.displayValue = ['Two'] >>> ctrl.value ['2'] >>> browser.getControl('Two').optionValue '2' >>> browser.getControl('Two').selected True >>> verifyObject(interfaces.IItemControl, browser.getControl('Two')) True >>> browser.getControl('Three').selected = True >>> browser.getControl('Three').selected True >>> browser.getControl('Two').selected True >>> ctrl.value ['2', '3'] >>> browser.getControl('Two').selected = False >>> ctrl.value ['3'] >>> browser.getControl('Three').selected = False >>> ctrl.value [] - Radio Control This is how you get a radio button based control: >>> ctrl = browser.getControl(name='radio-value') This shows the existing value of the control, as it was in the HTML received from the server: >>> ctrl.value ['2'] We can then unselect it: >>> ctrl.value = [] >>> ctrl.value [] We can also reselect it: >>> ctrl.value = ['2'] >>> ctrl.value ['2'] displayValue shows the text the user would see next to the control: >>> ctrl.displayValue ['Zwei'] This is just unit testing: >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.disabled False >>> ctrl.multiple False >>> ctrl.options ['1', '2', '3'] >>> ctrl.displayOptions ['Ein', 'Zwei', 'Drei'] >>> ctrl.displayValue = ['Ein'] >>> ctrl.value ['1'] >>> ctrl.displayValue ['Ein'] The radio control subcontrols were illustrated above. - Image Control >>> ctrl = browser.getControl(name='image-value') >>> ctrl >>> verifyObject(interfaces.IImageSubmitControl, ctrl) True >>> ctrl.value '' >>> ctrl.disabled False >>> ctrl.multiple False - Submit Control >>> ctrl = browser.getControl(name='submit-value') >>> ctrl >>> browser.getControl('Submit This') # value of submit button is a label >>> browser.getControl('Standard Submit Control') # label tag is legal >>> browser.getControl('Submit') # multiple labels, but same control >>> verifyObject(interfaces.ISubmitControl, ctrl) True >>> ctrl.value 'Submit This' >>> ctrl.disabled False >>> ctrl.multiple False Using Submitting Controls ~~~~~~~~~~~~~~~~~~~~~~~~~ Both the submit and image type should be clickable and submit the form: >>> browser.getControl('Text Control').value = 'Other Text' >>> browser.getControl('Submit').click() >>> print browser.contents ... Other Text ... Submit This ... Note that if you click a submit object after the associated page has expired, you will get an error. >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> ctrl = browser.getControl('Submit') >>> ctrl.click() >>> ctrl.click() Traceback (most recent call last): ... ExpiredError All the above also holds true for the image control: >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> browser.getControl('Text Control').value = 'Other Text' >>> browser.getControl(name='image-value').click() >>> print browser.contents ... Other Text ... 1 1 ... >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> ctrl = browser.getControl(name='image-value') >>> ctrl.click() >>> ctrl.click() Traceback (most recent call last): ... ExpiredError But when sending an image, you can also specify the coordinate you clicked: >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> browser.getControl(name='image-value').click((50,25)) >>> print browser.contents ... 50 25 ... Forms ----- Because pages can have multiple forms with like-named controls, it is sometimes necessary to access forms by name or id. The browser's `forms` attribute can be used to do so. The key value is the form's name or id. If more than one form has the same name or id, the first one will be returned. >>> browser.open('http://localhost/@@/testbrowser/forms.html') >>> form = browser.getForm(name='one') Form instances conform to the IForm interface. >>> verifyObject(interfaces.IForm, form) True The form exposes several attributes related to forms: - The name of the form: >>> form.name 'one' - The id of the form: >>> form.id '1' - The action (target URL) when the form is submitted: >>> form.action 'http://localhost/@@/testbrowser/forms.html' - The method (HTTP verb) used to transmit the form data: >>> form.method 'GET' Besides those attributes, you have also a couple of methods. Like for the browser, you can get control objects, but limited to the current form... >>> form.getControl(name='text-value') ...and submit the form. >>> form.submit('Submit') >>> print browser.contents ... First Text ... Submitting also works without specifying a control, as shown below, which is it's primary reason for existing in competition with the control submission discussed above. Now let me show you briefly that looking up forms is sometimes important. In the `forms.html` template, we have four forms all having a text control named `text-value`. Now, if I use the browser's `get` method, >>> browser.getControl(name='text-value') Traceback (most recent call last): ... AmbiguityError: name 'text-value' >>> browser.getControl('Text Control') Traceback (most recent call last): ... AmbiguityError: label 'Text Control' I'll always get an ambiguous form field. I can use the index argument, or with the `getForm` method I can disambiguate by searching only within a given form: >>> form = browser.getForm('2') >>> form.getControl(name='text-value').value 'Second Text' >>> form.submit('Submit') >>> browser.contents '...Second Text...' >>> form = browser.getForm('2') >>> form.getControl('Submit').click() >>> browser.contents '...Second Text...' >>> browser.getForm('3').getControl('Text Control').value 'Third Text' The last form on the page does not have a name, an id, or a submit button. Working with it is still easy, thanks to a index attribute that guarantees order. (Forms without submit buttons are sometimes useful for JavaScript.) >>> form = browser.getForm(index=3) >>> form.submit() >>> browser.contents '...Fourth Text...Submitted without the submit button....' If a form is requested that does not exists, an exception will be raised. >>> form = browser.getForm('does-not-exist') Traceback (most recent call last): LookupError If the HTML page contains only one form, no arguments to `getForm` are needed: >>> oneform = Browser() >>> oneform.open('http://localhost/@@/testbrowser/oneform.html') >>> form = oneform.getForm() If the HTML page contains more than one form, `index` is needed to disambiguate if no other arguments are provided: >>> browser.getForm() Traceback (most recent call last): ValueError: if no other arguments are given, index is required. Submitting a posts body directly -------------------------------- In addition to the open method, zope.testbrowser.testing.Browser has a ``post`` method that allows a request body to be supplied. This method is particularly helpful when testing Ajax methods. Let's visit a page that echos it's request: >>> browser.open('http://localhost/@@echo.html') >>> print browser.contents, HTTP_USER_AGENT: Python-urllib/2.4 HTTP_CONNECTION: close HTTP_COOKIE: REMOTE_ADDR: 127.0.0.1 HTTP_ACCEPT_LANGUAGE: en-US REQUEST_METHOD: GET HTTP_HOST: localhost PATH_INFO: /@@echo.html SERVER_PROTOCOL: HTTP/1.1 QUERY_STRING: Body: '' Now, we'll try a post. The post method takes a URL, a data string, and an optional content type. If we just pass a string, then a URL-encoded query string is assumed: >>> browser.post('http://localhost/@@echo.html', 'x=1&y=2') >>> print browser.contents, CONTENT_LENGTH: 7 HTTP_USER_AGENT: Python-urllib/2.4 HTTP_CONNECTION: close HTTP_COOKIE: REMOTE_ADDR: 127.0.0.1 HTTP_ACCEPT_LANGUAGE: en-US y: 2 REQUEST_METHOD: POST HTTP_HOST: localhost PATH_INFO: /@@echo.html CONTENT_TYPE: application/x-www-form-urlencoded SERVER_PROTOCOL: HTTP/1.1 QUERY_STRING: x: 1 Body: '' The body is empty because it is consumed to get form data. We can pass a content-type explicitly: >>> browser.post('http://localhost/@@echo.html', ... '{"x":1,"y":2}', 'application/x-javascript') >>> print browser.contents, CONTENT_LENGTH: 13 HTTP_USER_AGENT: Python-urllib/2.4 HTTP_CONNECTION: close HTTP_COOKIE: REMOTE_ADDR: 127.0.0.1 HTTP_ACCEPT_LANGUAGE: en-US REQUEST_METHOD: POST HTTP_HOST: localhost PATH_INFO: /@@echo.html CONTENT_TYPE: application/x-javascript SERVER_PROTOCOL: HTTP/1.1 Body: '{"x":1,"y":2}' Here, the body is left in place because it isn't form data. Performance Testing ------------------- Browser objects keep up with how much time each request takes. This can be used to ensure a particular request's performance is within a tolerable range. Be very careful using raw seconds, cross-machine differences can be huge, pystones is usually a better choice. >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.lastRequestSeconds < 10 # really big number for safety True >>> browser.lastRequestPystones < 10000 # really big number for safety True Handling Errors when using Zope 3's Publisher --------------------------------------------- A very useful feature of the publisher is the automatic graceful handling of application errors, such as invalid URLs: >>> browser.open('http://localhost/invalid') Traceback (most recent call last): ... HTTPError: HTTP Error 404: Not Found Note that the above error was thrown by ``mechanize`` and not by the publisher. For debugging purposes, however, it can be very useful to see the original exception caused by the application. In those cases you can set the ``handleErrors`` property of the browser to ``False``. It is defaulted to ``True``: >>> browser.handleErrors True So when we tell the publisher not to handle the errors, >>> browser.handleErrors = False we get a different, Zope internal error: >>> browser.open('http://localhost/invalid') Traceback (most recent call last): ... NotFound: Object: , name: u'invalid' NB: Setting the handleErrors attribute to False will only change anything if the http server you're testing is using Zope 3's publisher or can otherwise respond appropriately to an 'X-zope-handle-errors' header in requests. When the testbrowser is raising HttpErrors, the errors still hit the test. Sometimes we don't want that to happen, in situations where there are edge cases that will cause the error to be predictably but infrequently raised. Time is a primary cause of this. To get around this, one can set the raiseHttpErrors to False. >>> browser.handleErrors = True >>> browser.raiseHttpErrors = False This will cause HttpErrors not to propagate. >>> browser.open('http://localhost/invalid') The headers are still there, though. >>> '404 Not Found' in str(browser.headers) True If we don't handle the errors, and allow internal ones to propagate, however, this flag doesn't affect things. >>> browser.handleErrors = False >>> browser.open('http://localhost/invalid') Traceback (most recent call last): ... NotFound: Object: , name: u'invalid' >>> browser.raiseHttpErrors = True Hand-Holding ------------ Instances of the various objects ensure that users don't set incorrect instance attributes accidentally. >>> browser.nonexistant = None Traceback (most recent call last): ... AttributeError: 'Browser' object has no attribute 'nonexistant' >>> form.nonexistant = None Traceback (most recent call last): ... AttributeError: 'Form' object has no attribute 'nonexistant' >>> control.nonexistant = None Traceback (most recent call last): ...

AttributeError: 'Link' object has no attribute 'nonexistant' ======= CHANGES ======= 3.11.1 (2011-01-24) ------------------- - Fixing brown bag release 3.11.0. 3.11.0 (2011-01-24) ------------------- - Added `wsgi_intercept` support (came from ``zope.app.wsgi.testlayer``). 3.10.4 (2011-01-14) ------------------- - Move the over-the-wire.txt doctest out of the TestBrowserLayer as it doesn't need or use it. - Fix test compatibility with zope.app.testing 3.8.1. 3.10.3 (2010-10-15) ------------------- - Fixed backwards compatibility with ``zope.app.wsgi.testlayer``. 3.10.2 (2010-10-15) ------------------- - Fixed Python 2.7 compatibility in Browser.handleErrors. 3.10.1 (2010-09-21) ------------------- - Fixed a bug that caused the ``Browser`` to keep it's previous ``contents`` The places are: - Link.click() - SubmitControl.click() - ImageControl.click() - Form.submit() - Also adjusted exception messages at the above places to match pre version 3.4.1 messages. 3.10.0 (2010-09-14) ------------------- - LP #98437: use mechanize's built-in ``submit()`` to submit forms, allowing mechanize to set the "Referer:" (sic) header appropriately. - Fixed tests to run with ``zope.app.testing`` 3.8 and above. 3.9.0 (2010-05-17) ------------------ - LP #568806: Update dependency ``mechanize >= 0.2.0``, which now includes the ``ClientForm`` APIs. Remove use of ``urllib2`` APIs (incompatible with ``mechanize 0.2.0``) in favor of ``mechanize`` equivalents. Thanks to John J. Lee for the patch. - Use stdlib ``doctest`` module, instead of ``zope.testing.doctest``. - **Caution:** This version is no longer fully compatible with Python 2.4: ``handleErrors = False`` no longer works. 3.8.1 (2010-04-19) ------------------ - Pinned dependency on mechanize to prevent use of the upcoming 0.2.0 release before we have time to adjust to its API changes. - LP #98396: testbrowser resolves relative URLs incorrectly. 3.8.0 (2010-03-05) ------------------ - Added ``follow`` convenience method which gets and follows a link. 3.7.0 (2009-12-17) ------------------ - Moved zope.app.testing dependency into the scope of the PublisherConnection class. Zope2 specifies its own PublisherConnection which isn't dependent on zope.app.testing. - Fixed LP #419119: return None when the browser has no contents instead of raising an exception. 3.7.0a1 (2009-08-29) -------------------- - Remove dependency on zope.app.publisher in favor of zope.browserpage, zope.browserresource and zope.ptresource. - Remove dependencies on zope.app.principalannotation and zope.securitypolicy by using the simple PermissiveSecurityPolicy. We aren't testing security in our tests. - Replaced the testing dependency on zope.app.zcmlfiles with explicit dependencies of a minimal set of packages. - Remove unneeded zope.app.authentication from ftesting.zcml. - Test dependency on zope.securitypolicy instead of its app variant. 3.6.0a2 (2009-01-31) -------------------- - Test dependency on zope.site.folder instead of zope.app.folder. - Remove useless test dependency in zope.app.component. 3.6.0a1 (2009-01-08) -------------------- - Author e-mail to zope-dev rather than zope3-dev. - New lines are no longer stripped in XML and HTML code contained in a textarea; fix requires ClientForm >= 0.2.10 (LP #268139). - Added ``cookies`` attribute to browser for easy manipulation of browser cookies. See brief example in main documentation, plus new ``cookies.txt`` documentation. 3.5.1 (2008-10-10) ------------------ - Provide a work around for a mechanize/urllib2 bug on Python 2.6 missing 'timeout' attribute on 'Request' base class. - Provide a work around for a mechanize/urllib2 bug in creating request objects that won't handle fragment URLs correctly. 3.5.0 (2008-03-30) ------------------ - Added a zope.testbrowser.testing.Browser.post method that allows tests to supply a body and a content type. This is handy for testing Ajax requests with non-form input (e.g. JSON). - Remove vendor import of mechanize. - Fix bug that caused HTTP exception tracebacks to differ between version 3.4.0 and 3.4.1. - Workaround for bug in Python Cookie.SimpleCookie when handling unicode strings. - Fix bug introduced in 3.4.1 that created incompatible tracebacks in doctests. This necessitated adding a patched mechanize to the source tree; patches have been sent to the mechanize project. - Fix https://bugs.launchpad.net/bugs/149517 by adding zope.interface and zope.schema as real dependencies - Fix browser.getLink documentation that was not updated since the last API modification. - Move tests for fixed bugs to a separate file. - Removed non-functional and undocumented code intended to help test servers using virtual hosting. 3.4.2 (2007-10-31) ------------------ - Resolve ``ZopeSecurityPolicy`` deprecation warning. 3.4.1 (2007-09-01) ------------------ * Updated to mechanize 0.1.7b and ClientForm 0.2.7. These are now pulled in via egg dependencies. * ``zope.testbrowser`` now works on Python 2.5. 3.4.0 (2007-06-04) ------------------ * Added the ability to suppress raising exceptions on HTTP errors (``raiseHttpErrors`` attribute). * Made the tests more resilient to HTTP header formatting changes with the REnormalizer. 3.4.0a1 (2007-04-22) -------------------- Initial release as a separate project, corresponds to zope.testbrowser from Zope 3.4.0a1 Platform: UNKNOWN Classifier: Environment :: Web Environment Classifier: Intended Audience :: Developers Classifier: License :: OSI Approved :: Zope Public License Classifier: Programming Language :: Python Classifier: Topic :: Software Development :: Testing Classifier: Topic :: Internet :: WWW/HTTP zope2.13-2.13.21/source/zope.testbrowser/pip-egg-info/0000755000175000017500000000000012214017652021257 5ustar arnauarnauzope2.13-2.13.21/source/zope.testbrowser/pip-egg-info/zope.testbrowser.egg-info/0000755000175000017500000000000012214017652026310 5ustar arnauarnauzope2.13-2.13.21/source/zope.testbrowser/pip-egg-info/zope.testbrowser.egg-info/PKG-INFO0000644000175000017500000017061712214017652027421 0ustar arnauarnauMetadata-Version: 1.1 Name: zope.testbrowser Version: 3.11.1 Summary: Programmable browser for functional black-box tests Home-page: http://pypi.python.org/pypi/zope.testbrowser Author: Zope Corporation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: .. contents:: ``zope.testbrowser`` provides an easy-to-use programmable web browser with special focus on testing. It is used in Zope, but it's not Zope specific at all. For instance, it can be used to test or otherwise interact with any web site. ====================== Detailed Documentation ====================== Different Browsers ------------------ HTTP Browser ~~~~~~~~~~~~ The ``zope.testbrowser.browser`` module exposes a ``Browser`` class that simulates a web browser similar to Mozilla Firefox or IE. >>> from zope.testbrowser.browser import Browser >>> browser = Browser() This version of the browser object can be used to access any web site just as you would do using a normal web browser. WSGI Test Browser ~~~~~~~~~~~~~~~~~ There is also a special version of the ``Browser`` class which uses `wsgi_intercept`_ and can be used to do functional testing of WSGI applications, it can be imported from ``zope.testbrowser.wsgi``: >>> from zope.testbrowser.wsgi import Browser >>> browser = Browser() .. _`wsgi_intercept`: http://pypi.python.org/pypi/wsgi_intercept To use this browser you have to: * use the `wsgi` extra of the ``zope.testbrowser`` egg, * write a subclass of ``zope.testbrowser.wsgi.Layer`` and override the ``make_wsgi_app`` method, * use an instance of the class as the test layer of your test. Example: >>> import zope.testbrowser.wsgi >>> class SimpleLayer(zope.testbrowser.wsgi.Layer): ... def make_wsgi_app(self): ... return simple_app Where ``simple_app`` is the callable of your WSGI application. Zope 3 Test Browser ~~~~~~~~~~~~~~~~~~~ There is also a special version of the ``Browser`` class used to do functional testing of Zope 3 applications, it can be imported from ``zope.testbrowser.testing``: >>> from zope.testbrowser.testing import Browser >>> browser = Browser() Bowser Usage ------------ All browsers are used the same way. An initial page to load can be passed to the ``Browser`` constructor: >>> browser = Browser('http://localhost/@@/testbrowser/simple.html') >>> browser.url 'http://localhost/@@/testbrowser/simple.html' The browser can send arbitrary headers; this is helpful for setting the "Authorization" header or a language value, so that your tests format values the way you expect in your tests, if you rely on zope.i18n locale-based formatting or a similar approach. >>> browser.addHeader('Authorization', 'Basic mgr:mgrpw') >>> browser.addHeader('Accept-Language', 'en-US') An existing browser instance can also `open` web pages: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.url 'http://localhost/@@/testbrowser/simple.html' Once you have opened a web page initially, best practice for writing testbrowser doctests suggests using 'click' to navigate further (as discussed below), except in unusual circumstances. The test browser complies with the IBrowser interface; see ``zope.testbrowser.interfaces`` for full details on the interface. >>> from zope.testbrowser import interfaces >>> from zope.interface.verify import verifyObject >>> verifyObject(interfaces.IBrowser, browser) True Page Contents ------------- The contents of the current page are available: >>> print browser.contents Simple Page

Simple Page

Making assertions about page contents is easy. >>> '

Simple Page

' in browser.contents True Utilizing the doctest facilities, it also possible to do: >>> browser.contents '...

Simple Page

...' Note: Unfortunately, ellipsis (...) cannot be used at the beginning of the output (this is a limitation of doctest). Checking for HTML ----------------- Not all URLs return HTML. Of course our simple page does: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.isHtml True But if we load an image (or other binary file), we do not get HTML: >>> browser.open('http://localhost/@@/testbrowser/zope3logo.gif') >>> browser.isHtml False HTML Page Title ---------------- Another useful helper property is the title: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.title 'Simple Page' If a page does not provide a title, it is simply ``None``: >>> browser.open('http://localhost/@@/testbrowser/notitle.html') >>> browser.title However, if the output is not HTML, then an error will occur trying to access the title: >>> browser.open('http://localhost/@@/testbrowser/zope3logo.gif') >>> browser.title Traceback (most recent call last): ... BrowserStateError: not viewing HTML Headers ------- As you can see, the `contents` of the browser does not return any HTTP headers. The headers are accessible via a separate attribute, which is an ``httplib.HTTPMessage`` instance (httplib is a part of Python's standard library): >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.headers The headers can be accessed as a string: >>> print browser.headers Status: 200 OK Content-Length: 123 Content-Type: text/html;charset=utf-8 X-Powered-By: Zope (www.zope.org), Python (www.python.org) Or as a mapping: >>> browser.headers['content-type'] 'text/html;charset=utf-8' Cookies ------- When a Set-Cookie header is available, it can be found in the headers, as seen above. Here, we use a view that will make the server set cookies with the values we provide. >>> browser.open('http://localhost/set_cookie.html?name=foo&value=bar') >>> browser.headers['set-cookie'].replace(';', '') 'foo=bar' It is also available in the browser's ``cookies`` attribute. This is an extended mapping interface that allows getting, setting, and deleting the cookies that the browser is remembering *for the current url*. Here are a few examples. >>> browser.cookies['foo'] 'bar' >>> browser.cookies.keys() ['foo'] >>> browser.cookies.values() ['bar'] >>> browser.cookies.items() [('foo', 'bar')] >>> 'foo' in browser.cookies True >>> 'bar' in browser.cookies False >>> len(browser.cookies) 1 >>> print(dict(browser.cookies)) {'foo': 'bar'} >>> browser.cookies['sha'] = 'zam' >>> len(browser.cookies) 2 >>> sorted(browser.cookies.items()) [('foo', 'bar'), ('sha', 'zam')] >>> browser.open('http://localhost/get_cookie.html') >>> print browser.headers.get('set-cookie') None >>> print browser.contents # server got the cookie change foo: bar sha: zam >>> sorted(browser.cookies.items()) [('foo', 'bar'), ('sha', 'zam')] >>> browser.cookies.clearAll() >>> len(browser.cookies) 0 Many more examples, and a discussion of the additional methods available, can be found in cookies.txt. Navigation and Link Objects --------------------------- If you want to simulate clicking on a link, get the link and `click` on it. In the `navigate.html` file there are several links set up to demonstrate the capabilities of the link objects and their `click` method. The simplest way to get a link is via the anchor text. In other words the text you would see in a browser (text and url searches are substring searches): >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...Link Text...' >>> link = browser.getLink('Link Text') >>> link Link objects comply with the ILink interface. >>> verifyObject(interfaces.ILink, link) True Links expose several attributes for easy access. >>> link.text 'Link Text' >>> link.tag # links can also be image maps. 'a' >>> link.url # it's normalized 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text' >>> link.attrs {'href': 'navigate.html?message=By+Link+Text'} Links can be "clicked" and the browser will navigate to the referenced URL. >>> link.click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text' >>> browser.contents '...Message: By Link Text...' When finding a link by its text, whitespace is normalized. >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...> Link Text \n with Whitespace\tNormalization (and parens) >> link = browser.getLink('Link Text with Whitespace Normalization ' ... '(and parens)') >>> link >>> link.text 'Link Text with Whitespace Normalization (and parens)' >>> link.click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text+with+Normalization' >>> browser.contents '...Message: By Link Text with Normalization...' When a link text matches more than one link, by default the first one is chosen. You can, however, specify the index of the link and thus retrieve a later matching link: >>> browser.getLink('Link Text') >>> browser.getLink('Link Text', index=1) Note that clicking a link object after its browser page has expired will generate an error. >>> link.click() Traceback (most recent call last): ... ExpiredError You can also find the link by its URL, >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...Using the URL...' >>> browser.getLink(url='?message=By+URL').click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+URL' >>> browser.contents '...Message: By URL...' or its id: >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...By Anchor Id...' >>> browser.getLink(id='anchorid').click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Id' >>> browser.contents '...Message: By Id...' You thought we were done here? Not so quickly. The `getLink` method also supports image maps, though not by specifying the coordinates, but using the area's id: >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> link = browser.getLink(id='zope3') >>> link.tag 'area' >>> link.click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=Zope+3+Name' >>> browser.contents '...Message: Zope 3 Name...' Getting a nonexistent link raises an exception. >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.getLink('This does not exist') Traceback (most recent call last): ... LinkNotFoundError A convenience method is provided to follow links; this uses the same arguments as `getLink`, but clicks on the link instead of returning the link object. >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...Link Text...' >>> browser.follow('Link Text') >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text' >>> browser.contents '...Message: By Link Text...' >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.follow(url='?message=By+URL') >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+URL' >>> browser.contents '...Message: By URL...' >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.follow(id='zope3') >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=Zope+3+Name' >>> browser.contents '...Message: Zope 3 Name...' Attempting to follow links that don't exist raises the same exception as asking for the link object: >>> browser.follow('This does not exist') Traceback (most recent call last): ... LinkNotFoundError Other Navigation ---------------- Like in any normal browser, you can reload a page: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.url 'http://localhost/@@/testbrowser/simple.html' >>> browser.reload() >>> browser.url 'http://localhost/@@/testbrowser/simple.html' You can also go back: >>> browser.open('http://localhost/@@/testbrowser/notitle.html') >>> browser.url 'http://localhost/@@/testbrowser/notitle.html' >>> browser.goBack() >>> browser.url 'http://localhost/@@/testbrowser/simple.html' Controls -------- One of the most important features of the browser is the ability to inspect and fill in values for the controls of input forms. To do so, let's first open a page that has a bunch of controls: >>> browser.open('http://localhost/@@/testbrowser/controls.html') Obtaining a Control ~~~~~~~~~~~~~~~~~~~ You look up browser controls with the 'getControl' method. The default first argument is 'label', and looks up the form on the basis of any associated label. >>> control = browser.getControl('Text Control') >>> control >>> browser.getControl(label='Text Control') # equivalent If you request a control that doesn't exist, the code raises a LookupError: >>> browser.getControl('Does Not Exist') Traceback (most recent call last): ... LookupError: label 'Does Not Exist' If you request a control with an ambiguous lookup, the code raises an AmbiguityError. >>> browser.getControl('Ambiguous Control') Traceback (most recent call last): ... AmbiguityError: label 'Ambiguous Control' This is also true if an option in a control is ambiguous in relation to the control itself. >>> browser.getControl('Sub-control Ambiguity') Traceback (most recent call last): ... AmbiguityError: label 'Sub-control Ambiguity' Ambiguous controls may be specified using an index value. We use the control's value attribute to show the two controls; this attribute is properly introduced below. >>> browser.getControl('Ambiguous Control', index=0) >>> browser.getControl('Ambiguous Control', index=0).value 'First' >>> browser.getControl('Ambiguous Control', index=1).value 'Second' >>> browser.getControl('Sub-control Ambiguity', index=0) >>> browser.getControl('Sub-control Ambiguity', index=1).optionValue 'ambiguous' Label searches are against stripped, whitespace-normalized, no-tag versions of the text. Text applied to searches is also stripped and whitespace normalized. The search finds results if the text search finds the whole words of your text in a label. Thus, for instance, a search for 'Add' will match the label 'Add a Client' but not 'Address'. Case is honored. >>> browser.getControl('Label Needs Whitespace Normalization') >>> browser.getControl('label needs whitespace normalization') Traceback (most recent call last): ... LookupError: label 'label needs whitespace normalization' >>> browser.getControl(' Label Needs Whitespace ') >>> browser.getControl('Whitespace') >>> browser.getControl('hitespace') Traceback (most recent call last): ... LookupError: label 'hitespace' >>> browser.getControl('[non word characters should not confuse]') Multiple labels can refer to the same control (simply because that is possible in the HTML 4.0 spec). >>> browser.getControl('Multiple labels really') >>> browser.getControl('really are possible') >>> browser.getControl('really') # OK: ambiguous labels, but not ambiguous control A label can be connected with a control using the 'for' attribute and also by containing a control. >>> browser.getControl( ... 'Labels can be connected by containing their respective fields') Get also accepts one other search argument, 'name'. Only one of 'label' and 'name' may be used at a time. The 'name' keyword searches form field names. >>> browser.getControl(name='text-value') >>> browser.getControl(name='ambiguous-control-name') Traceback (most recent call last): ... AmbiguityError: name 'ambiguous-control-name' >>> browser.getControl(name='does-not-exist') Traceback (most recent call last): ... LookupError: name 'does-not-exist' >>> browser.getControl(name='ambiguous-control-name', index=1).value 'Second' Combining 'label' and 'name' raises a ValueError, as does supplying neither of them. >>> browser.getControl(label='Ambiguous Control', name='ambiguous-control-name') Traceback (most recent call last): ... ValueError: Supply one and only one of "label" and "name" as arguments >>> browser.getControl() Traceback (most recent call last): ... ValueError: Supply one and only one of "label" and "name" as arguments Radio and checkbox fields are unusual in that their labels and names may point to different objects: names point to logical collections of radio buttons or checkboxes, but labels may only be used for individual choices within the logical collection. This means that obtaining a radio button by label gets a different object than obtaining the radio collection by name. Select options may also be searched by label. >>> browser.getControl(name='radio-value') >>> browser.getControl('Zwei') >>> browser.getControl('One') >>> browser.getControl('Tres') Characteristics of controls and subcontrols are discussed below. Control Objects ~~~~~~~~~~~~~~~ Controls provide IControl. >>> ctrl = browser.getControl('Text Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True They have several useful attributes: - the name as which the control is known to the form: >>> ctrl.name 'text-value' - the value of the control, which may also be set: >>> ctrl.value 'Some Text' >>> ctrl.value = 'More Text' >>> ctrl.value 'More Text' - the type of the control: >>> ctrl.type 'text' - a flag describing whether the control is disabled: >>> ctrl.disabled False - and a flag to tell us whether the control can have multiple values: >>> ctrl.multiple False Additionally, controllers for select, radio, and checkbox provide IListControl. These fields have four other attributes and an additional method: >>> ctrl = browser.getControl('Multiple Select Control') >>> ctrl >>> ctrl.disabled False >>> ctrl.multiple True >>> verifyObject(interfaces.IListControl, ctrl) True - 'options' lists all available value options. >>> ctrl.options ['1', '2', '3'] - 'displayOptions' lists all available options by label. The 'label' attribute on an option has precedence over its contents, which is why our last option is 'Third' in the display. >>> ctrl.displayOptions ['Un', 'Deux', 'Third'] - 'displayValue' lets you get and set the displayed values of the control of the select box, rather than the actual values. >>> ctrl.value [] >>> ctrl.displayValue [] >>> ctrl.displayValue = ['Un', 'Deux'] >>> ctrl.displayValue ['Un', 'Deux'] >>> ctrl.value ['1', '2'] - 'controls' gives you a list of the subcontrol objects in the control (subcontrols are discussed below). >>> ctrl.controls [, , ] - The 'getControl' method lets you get subcontrols by their label or their value. >>> ctrl.getControl('Un') >>> ctrl.getControl('Deux') >>> ctrl.getControl('Trois') # label attribute >>> ctrl.getControl('Third') # contents >>> browser.getControl('Third') # ambiguous in the browser, so useful Traceback (most recent call last): ... AmbiguityError: label 'Third' Finally, submit controls provide ISubmitControl, and image controls provide IImageSubmitControl, which extents ISubmitControl. These both simply add a 'click' method. For image submit controls, you may also provide a coordinates argument, which is a tuple of (x, y). These submit the forms, and are demonstrated below as we examine each control individually. ItemControl Objects ~~~~~~~~~~~~~~~~~~~ As introduced briefly above, using labels to obtain elements of a logical radio button or checkbox collection returns item controls, which are parents. Manipulating the value of these controls affects the parent control. >>> browser.getControl(name='radio-value').value ['2'] >>> browser.getControl('Zwei').optionValue # read-only. '2' >>> browser.getControl('Zwei').selected True >>> verifyObject(interfaces.IItemControl, browser.getControl('Zwei')) True >>> browser.getControl('Ein').selected = True >>> browser.getControl('Ein').selected True >>> browser.getControl('Zwei').selected False >>> browser.getControl(name='radio-value').value ['1'] >>> browser.getControl('Ein').selected = False >>> browser.getControl(name='radio-value').value [] >>> browser.getControl('Zwei').selected = True Checkbox collections behave similarly, as shown below. Controls with subcontrols-- Various Controls ~~~~~~~~~~~~~~~~ The various types of controls are demonstrated here. - Text Control The text control we already introduced above. - Password Control >>> ctrl = browser.getControl('Password Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value 'Password' >>> ctrl.value = 'pass now' >>> ctrl.value 'pass now' >>> ctrl.disabled False >>> ctrl.multiple False - Hidden Control >>> ctrl = browser.getControl(name='hidden-value') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value 'Hidden' >>> ctrl.value = 'More Hidden' >>> ctrl.disabled False >>> ctrl.multiple False - Text Area Control >>> ctrl = browser.getControl('Text Area Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value ' Text inside\n area!\n ' >>> ctrl.value = 'A lot of\n text.' >>> ctrl.disabled False >>> ctrl.multiple False - File Control File controls are used when a form has a file-upload field. To specify data, call the add_file method, passing: - A file-like object - a content type, and - a file name >>> ctrl = browser.getControl('File Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value is None True >>> import cStringIO >>> ctrl.add_file(cStringIO.StringIO('File contents'), ... 'text/plain', 'test.txt') The file control (like the other controls) also knows if it is disabled or if it can have multiple values. >>> ctrl.disabled False >>> ctrl.multiple False - Selection Control (Single-Valued) >>> ctrl = browser.getControl('Single Select Control') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value ['1'] >>> ctrl.value = ['2'] >>> ctrl.disabled False >>> ctrl.multiple False >>> ctrl.options ['1', '2', '3'] >>> ctrl.displayOptions ['Uno', 'Dos', 'Third'] >>> ctrl.displayValue ['Dos'] >>> ctrl.displayValue = ['Tres'] >>> ctrl.displayValue ['Third'] >>> ctrl.displayValue = ['Dos'] >>> ctrl.displayValue ['Dos'] >>> ctrl.displayValue = ['Third'] >>> ctrl.displayValue ['Third'] >>> ctrl.value ['3'] - Selection Control (Multi-Valued) This was already demonstrated in the introduction to control objects above. - Checkbox Control (Single-Valued; Unvalued) >>> ctrl = browser.getControl(name='single-unvalued-checkbox-value') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value True >>> ctrl.value = False >>> ctrl.disabled False >>> ctrl.multiple True >>> ctrl.options [True] >>> ctrl.displayOptions ['Single Unvalued Checkbox'] >>> ctrl.displayValue [] >>> verifyObject( ... interfaces.IItemControl, ... browser.getControl('Single Unvalued Checkbox')) True >>> browser.getControl('Single Unvalued Checkbox').optionValue 'on' >>> browser.getControl('Single Unvalued Checkbox').selected False >>> ctrl.displayValue = ['Single Unvalued Checkbox'] >>> ctrl.displayValue ['Single Unvalued Checkbox'] >>> browser.getControl('Single Unvalued Checkbox').selected True >>> browser.getControl('Single Unvalued Checkbox').selected = False >>> browser.getControl('Single Unvalued Checkbox').selected False >>> ctrl.displayValue [] >>> browser.getControl( ... name='single-disabled-unvalued-checkbox-value').disabled True - Checkbox Control (Single-Valued, Valued) >>> ctrl = browser.getControl(name='single-valued-checkbox-value') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value ['1'] >>> ctrl.value = [] >>> ctrl.disabled False >>> ctrl.multiple True >>> ctrl.options ['1'] >>> ctrl.displayOptions ['Single Valued Checkbox'] >>> ctrl.displayValue [] >>> verifyObject( ... interfaces.IItemControl, ... browser.getControl('Single Valued Checkbox')) True >>> browser.getControl('Single Valued Checkbox').selected False >>> browser.getControl('Single Valued Checkbox').optionValue '1' >>> ctrl.displayValue = ['Single Valued Checkbox'] >>> ctrl.displayValue ['Single Valued Checkbox'] >>> browser.getControl('Single Valued Checkbox').selected True >>> browser.getControl('Single Valued Checkbox').selected = False >>> browser.getControl('Single Valued Checkbox').selected False >>> ctrl.displayValue [] - Checkbox Control (Multi-Valued) >>> ctrl = browser.getControl(name='multi-checkbox-value') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value ['1', '3'] >>> ctrl.value = ['1', '2'] >>> ctrl.disabled False >>> ctrl.multiple True >>> ctrl.options ['1', '2', '3'] >>> ctrl.displayOptions ['One', 'Two', 'Three'] >>> ctrl.displayValue ['One', 'Two'] >>> ctrl.displayValue = ['Two'] >>> ctrl.value ['2'] >>> browser.getControl('Two').optionValue '2' >>> browser.getControl('Two').selected True >>> verifyObject(interfaces.IItemControl, browser.getControl('Two')) True >>> browser.getControl('Three').selected = True >>> browser.getControl('Three').selected True >>> browser.getControl('Two').selected True >>> ctrl.value ['2', '3'] >>> browser.getControl('Two').selected = False >>> ctrl.value ['3'] >>> browser.getControl('Three').selected = False >>> ctrl.value [] - Radio Control This is how you get a radio button based control: >>> ctrl = browser.getControl(name='radio-value') This shows the existing value of the control, as it was in the HTML received from the server: >>> ctrl.value ['2'] We can then unselect it: >>> ctrl.value = [] >>> ctrl.value [] We can also reselect it: >>> ctrl.value = ['2'] >>> ctrl.value ['2'] displayValue shows the text the user would see next to the control: >>> ctrl.displayValue ['Zwei'] This is just unit testing: >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.disabled False >>> ctrl.multiple False >>> ctrl.options ['1', '2', '3'] >>> ctrl.displayOptions ['Ein', 'Zwei', 'Drei'] >>> ctrl.displayValue = ['Ein'] >>> ctrl.value ['1'] >>> ctrl.displayValue ['Ein'] The radio control subcontrols were illustrated above. - Image Control >>> ctrl = browser.getControl(name='image-value') >>> ctrl >>> verifyObject(interfaces.IImageSubmitControl, ctrl) True >>> ctrl.value '' >>> ctrl.disabled False >>> ctrl.multiple False - Submit Control >>> ctrl = browser.getControl(name='submit-value') >>> ctrl >>> browser.getControl('Submit This') # value of submit button is a label >>> browser.getControl('Standard Submit Control') # label tag is legal >>> browser.getControl('Submit') # multiple labels, but same control >>> verifyObject(interfaces.ISubmitControl, ctrl) True >>> ctrl.value 'Submit This' >>> ctrl.disabled False >>> ctrl.multiple False Using Submitting Controls ~~~~~~~~~~~~~~~~~~~~~~~~~ Both the submit and image type should be clickable and submit the form: >>> browser.getControl('Text Control').value = 'Other Text' >>> browser.getControl('Submit').click() >>> print browser.contents ... Other Text ... Submit This ... Note that if you click a submit object after the associated page has expired, you will get an error. >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> ctrl = browser.getControl('Submit') >>> ctrl.click() >>> ctrl.click() Traceback (most recent call last): ... ExpiredError All the above also holds true for the image control: >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> browser.getControl('Text Control').value = 'Other Text' >>> browser.getControl(name='image-value').click() >>> print browser.contents ... Other Text ... 1 1 ... >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> ctrl = browser.getControl(name='image-value') >>> ctrl.click() >>> ctrl.click() Traceback (most recent call last): ... ExpiredError But when sending an image, you can also specify the coordinate you clicked: >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> browser.getControl(name='image-value').click((50,25)) >>> print browser.contents ... 50 25 ... Forms ----- Because pages can have multiple forms with like-named controls, it is sometimes necessary to access forms by name or id. The browser's `forms` attribute can be used to do so. The key value is the form's name or id. If more than one form has the same name or id, the first one will be returned. >>> browser.open('http://localhost/@@/testbrowser/forms.html') >>> form = browser.getForm(name='one') Form instances conform to the IForm interface. >>> verifyObject(interfaces.IForm, form) True The form exposes several attributes related to forms: - The name of the form: >>> form.name 'one' - The id of the form: >>> form.id '1' - The action (target URL) when the form is submitted: >>> form.action 'http://localhost/@@/testbrowser/forms.html' - The method (HTTP verb) used to transmit the form data: >>> form.method 'GET' Besides those attributes, you have also a couple of methods. Like for the browser, you can get control objects, but limited to the current form... >>> form.getControl(name='text-value') ...and submit the form. >>> form.submit('Submit') >>> print browser.contents ... First Text ... Submitting also works without specifying a control, as shown below, which is it's primary reason for existing in competition with the control submission discussed above. Now let me show you briefly that looking up forms is sometimes important. In the `forms.html` template, we have four forms all having a text control named `text-value`. Now, if I use the browser's `get` method, >>> browser.getControl(name='text-value') Traceback (most recent call last): ... AmbiguityError: name 'text-value' >>> browser.getControl('Text Control') Traceback (most recent call last): ... AmbiguityError: label 'Text Control' I'll always get an ambiguous form field. I can use the index argument, or with the `getForm` method I can disambiguate by searching only within a given form: >>> form = browser.getForm('2') >>> form.getControl(name='text-value').value 'Second Text' >>> form.submit('Submit') >>> browser.contents '...Second Text...' >>> form = browser.getForm('2') >>> form.getControl('Submit').click() >>> browser.contents '...Second Text...' >>> browser.getForm('3').getControl('Text Control').value 'Third Text' The last form on the page does not have a name, an id, or a submit button. Working with it is still easy, thanks to a index attribute that guarantees order. (Forms without submit buttons are sometimes useful for JavaScript.) >>> form = browser.getForm(index=3) >>> form.submit() >>> browser.contents '...Fourth Text...Submitted without the submit button....' If a form is requested that does not exists, an exception will be raised. >>> form = browser.getForm('does-not-exist') Traceback (most recent call last): LookupError If the HTML page contains only one form, no arguments to `getForm` are needed: >>> oneform = Browser() >>> oneform.open('http://localhost/@@/testbrowser/oneform.html') >>> form = oneform.getForm() If the HTML page contains more than one form, `index` is needed to disambiguate if no other arguments are provided: >>> browser.getForm() Traceback (most recent call last): ValueError: if no other arguments are given, index is required. Submitting a posts body directly -------------------------------- In addition to the open method, zope.testbrowser.testing.Browser has a ``post`` method that allows a request body to be supplied. This method is particularly helpful when testing Ajax methods. Let's visit a page that echos it's request: >>> browser.open('http://localhost/@@echo.html') >>> print browser.contents, HTTP_USER_AGENT: Python-urllib/2.4 HTTP_CONNECTION: close HTTP_COOKIE: REMOTE_ADDR: 127.0.0.1 HTTP_ACCEPT_LANGUAGE: en-US REQUEST_METHOD: GET HTTP_HOST: localhost PATH_INFO: /@@echo.html SERVER_PROTOCOL: HTTP/1.1 QUERY_STRING: Body: '' Now, we'll try a post. The post method takes a URL, a data string, and an optional content type. If we just pass a string, then a URL-encoded query string is assumed: >>> browser.post('http://localhost/@@echo.html', 'x=1&y=2') >>> print browser.contents, CONTENT_LENGTH: 7 HTTP_USER_AGENT: Python-urllib/2.4 HTTP_CONNECTION: close HTTP_COOKIE: REMOTE_ADDR: 127.0.0.1 HTTP_ACCEPT_LANGUAGE: en-US y: 2 REQUEST_METHOD: POST HTTP_HOST: localhost PATH_INFO: /@@echo.html CONTENT_TYPE: application/x-www-form-urlencoded SERVER_PROTOCOL: HTTP/1.1 QUERY_STRING: x: 1 Body: '' The body is empty because it is consumed to get form data. We can pass a content-type explicitly: >>> browser.post('http://localhost/@@echo.html', ... '{"x":1,"y":2}', 'application/x-javascript') >>> print browser.contents, CONTENT_LENGTH: 13 HTTP_USER_AGENT: Python-urllib/2.4 HTTP_CONNECTION: close HTTP_COOKIE: REMOTE_ADDR: 127.0.0.1 HTTP_ACCEPT_LANGUAGE: en-US REQUEST_METHOD: POST HTTP_HOST: localhost PATH_INFO: /@@echo.html CONTENT_TYPE: application/x-javascript SERVER_PROTOCOL: HTTP/1.1 Body: '{"x":1,"y":2}' Here, the body is left in place because it isn't form data. Performance Testing ------------------- Browser objects keep up with how much time each request takes. This can be used to ensure a particular request's performance is within a tolerable range. Be very careful using raw seconds, cross-machine differences can be huge, pystones is usually a better choice. >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.lastRequestSeconds < 10 # really big number for safety True >>> browser.lastRequestPystones < 10000 # really big number for safety True Handling Errors when using Zope 3's Publisher --------------------------------------------- A very useful feature of the publisher is the automatic graceful handling of application errors, such as invalid URLs: >>> browser.open('http://localhost/invalid') Traceback (most recent call last): ... HTTPError: HTTP Error 404: Not Found Note that the above error was thrown by ``mechanize`` and not by the publisher. For debugging purposes, however, it can be very useful to see the original exception caused by the application. In those cases you can set the ``handleErrors`` property of the browser to ``False``. It is defaulted to ``True``: >>> browser.handleErrors True So when we tell the publisher not to handle the errors, >>> browser.handleErrors = False we get a different, Zope internal error: >>> browser.open('http://localhost/invalid') Traceback (most recent call last): ... NotFound: Object: , name: u'invalid' NB: Setting the handleErrors attribute to False will only change anything if the http server you're testing is using Zope 3's publisher or can otherwise respond appropriately to an 'X-zope-handle-errors' header in requests. When the testbrowser is raising HttpErrors, the errors still hit the test. Sometimes we don't want that to happen, in situations where there are edge cases that will cause the error to be predictably but infrequently raised. Time is a primary cause of this. To get around this, one can set the raiseHttpErrors to False. >>> browser.handleErrors = True >>> browser.raiseHttpErrors = False This will cause HttpErrors not to propagate. >>> browser.open('http://localhost/invalid') The headers are still there, though. >>> '404 Not Found' in str(browser.headers) True If we don't handle the errors, and allow internal ones to propagate, however, this flag doesn't affect things. >>> browser.handleErrors = False >>> browser.open('http://localhost/invalid') Traceback (most recent call last): ... NotFound: Object: , name: u'invalid' >>> browser.raiseHttpErrors = True Hand-Holding ------------ Instances of the various objects ensure that users don't set incorrect instance attributes accidentally. >>> browser.nonexistant = None Traceback (most recent call last): ... AttributeError: 'Browser' object has no attribute 'nonexistant' >>> form.nonexistant = None Traceback (most recent call last): ... AttributeError: 'Form' object has no attribute 'nonexistant' >>> control.nonexistant = None Traceback (most recent call last): ... AttributeError: 'Control' object has no attribute 'nonexistant' >>> link.nonexistant = None Traceback (most recent call last): ... AttributeError: 'Link' object has no attribute 'nonexistant' ======= CHANGES ======= 3.11.1 (2011-01-24) ------------------- - Fixing brown bag release 3.11.0. 3.11.0 (2011-01-24) ------------------- - Added `wsgi_intercept` support (came from ``zope.app.wsgi.testlayer``). 3.10.4 (2011-01-14) ------------------- - Move the over-the-wire.txt doctest out of the TestBrowserLayer as it doesn't need or use it. - Fix test compatibility with zope.app.testing 3.8.1. 3.10.3 (2010-10-15) ------------------- - Fixed backwards compatibility with ``zope.app.wsgi.testlayer``. 3.10.2 (2010-10-15) ------------------- - Fixed Python 2.7 compatibility in Browser.handleErrors. 3.10.1 (2010-09-21) ------------------- - Fixed a bug that caused the ``Browser`` to keep it's previous ``contents`` The places are: - Link.click() - SubmitControl.click() - ImageControl.click() - Form.submit() - Also adjusted exception messages at the above places to match pre version 3.4.1 messages. 3.10.0 (2010-09-14) ------------------- - LP #98437: use mechanize's built-in ``submit()`` to submit forms, allowing mechanize to set the "Referer:" (sic) header appropriately. - Fixed tests to run with ``zope.app.testing`` 3.8 and above. 3.9.0 (2010-05-17) ------------------ - LP #568806: Update dependency ``mechanize >= 0.2.0``, which now includes the ``ClientForm`` APIs. Remove use of ``urllib2`` APIs (incompatible with ``mechanize 0.2.0``) in favor of ``mechanize`` equivalents. Thanks to John J. Lee for the patch. - Use stdlib ``doctest`` module, instead of ``zope.testing.doctest``. - **Caution:** This version is no longer fully compatible with Python 2.4: ``handleErrors = False`` no longer works. 3.8.1 (2010-04-19) ------------------ - Pinned dependency on mechanize to prevent use of the upcoming 0.2.0 release before we have time to adjust to its API changes. - LP #98396: testbrowser resolves relative URLs incorrectly. 3.8.0 (2010-03-05) ------------------ - Added ``follow`` convenience method which gets and follows a link. 3.7.0 (2009-12-17) ------------------ - Moved zope.app.testing dependency into the scope of the PublisherConnection class. Zope2 specifies its own PublisherConnection which isn't dependent on zope.app.testing. - Fixed LP #419119: return None when the browser has no contents instead of raising an exception. 3.7.0a1 (2009-08-29) -------------------- - Remove dependency on zope.app.publisher in favor of zope.browserpage, zope.browserresource and zope.ptresource. - Remove dependencies on zope.app.principalannotation and zope.securitypolicy by using the simple PermissiveSecurityPolicy. We aren't testing security in our tests. - Replaced the testing dependency on zope.app.zcmlfiles with explicit dependencies of a minimal set of packages. - Remove unneeded zope.app.authentication from ftesting.zcml. - Test dependency on zope.securitypolicy instead of its app variant. 3.6.0a2 (2009-01-31) -------------------- - Test dependency on zope.site.folder instead of zope.app.folder. - Remove useless test dependency in zope.app.component. 3.6.0a1 (2009-01-08) -------------------- - Author e-mail to zope-dev rather than zope3-dev. - New lines are no longer stripped in XML and HTML code contained in a textarea; fix requires ClientForm >= 0.2.10 (LP #268139). - Added ``cookies`` attribute to browser for easy manipulation of browser cookies. See brief example in main documentation, plus new ``cookies.txt`` documentation. 3.5.1 (2008-10-10) ------------------ - Provide a work around for a mechanize/urllib2 bug on Python 2.6 missing 'timeout' attribute on 'Request' base class. - Provide a work around for a mechanize/urllib2 bug in creating request objects that won't handle fragment URLs correctly. 3.5.0 (2008-03-30) ------------------ - Added a zope.testbrowser.testing.Browser.post method that allows tests to supply a body and a content type.

These are now pulled in via egg dependencies. * ``zope.testbrowser`` now works on Python 2.5. 3.4.0 (2007-06-04) ------------------ * Added the ability to suppress raising exceptions on HTTP errors (``raiseHttpErrors`` attribute). * Made the tests more resilient to HTTP header formatting changes with the REnormalizer. 3.4.0a1 (2007-04-22) -------------------- Initial release as a separate project, corresponds to zope.testbrowser from Zope 3.4.0a1 zope2.13-2.13.21/source/zope.testbrowser/src/0000755000175000017500000000000012214017652017565 5ustar arnauarnauzope2.13-2.13.21/source/zope.testbrowser/src/zope/0000755000175000017500000000000012214017652020542 5ustar arnauarnauzope2.13-2.13.21/source/zope.testbrowser/src/zope/testbrowser/0000755000175000017500000000000012214017652023125 5ustar arnauarnauzope2.13-2.13.21/source/zope.testbrowser/src/zope/testbrowser/browser.py0000644000175000017500000006337112214017652025174 0ustar arnauarnau############################################################################## # # Copyright (c) 2005 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

RuntimeError: no request found >>> browser.cookies.keys() Traceback (most recent call last): ... RuntimeError: no request found Once you send the browser to a URL, the cookies attribute can be used. >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> len(browser.cookies) 0 >>> browser.cookies.keys() [] >>> browser.url 'http://localhost/@@/testbrowser/simple.html' >>> browser.cookies.url 'http://localhost/@@/testbrowser/simple.html' >>> import zope.testbrowser.interfaces >>> from zope.interface.verify import verifyObject >>> verifyObject(zope.testbrowser.interfaces.ICookies, browser.cookies) True Alternatively, you can use the ``forURL`` method to get another instance of the cookies mapping for the given URL. >>> len(browser.cookies.forURL('http://www.example.com')) 0 >>> browser.cookies.forURL('http://www.example.com').keys() [] >>> browser.cookies.forURL('http://www.example.com').url 'http://www.example.com' >>> browser.url 'http://localhost/@@/testbrowser/simple.html' >>> browser.cookies.url 'http://localhost/@@/testbrowser/simple.html' Here, we use a view that will make the server set cookies with the values we provide. >>> browser.open('http://localhost/set_cookie.html?name=foo&value=bar') >>> browser.headers['set-cookie'].replace(';', '') 'foo=bar' Basic Mapping Interface ======================= Now the cookies for localhost have a value. These are examples of just the basic accessor operators and methods. >>> browser.cookies['foo'] 'bar' >>> browser.cookies.keys() ['foo'] >>> browser.cookies.values() ['bar'] >>> browser.cookies.items() [('foo', 'bar')] >>> 'foo' in browser.cookies True >>> 'bar' in browser.cookies False >>> len(browser.cookies) 1 >>> print(dict(browser.cookies)) {'foo': 'bar'} As you would expect, the cookies attribute can also be used to examine cookies that have already been set in a previous request. To demonstrate this, we use another view that does not set cookies but reports on the cookies it receives from the browser. >>> browser.open('http://localhost/get_cookie.html') >>> print browser.headers.get('set-cookie') None >>> browser.contents 'foo: bar' >>> browser.cookies['foo'] 'bar' The standard mapping mutation methods and operators are also available, as seen here. >>> browser.cookies['sha'] = 'zam' >>> len(browser.cookies) 2 >>> import pprint >>> pprint.pprint(sorted(browser.cookies.items())) [('foo', 'bar'), ('sha', 'zam')] >>> browser.open('http://localhost/get_cookie.html') >>> print browser.headers.get('set-cookie') None >>> print browser.contents # server got the cookie change foo: bar sha: zam >>> browser.cookies.update({'va': 'voom', 'tweedle': 'dee'}) >>> pprint.pprint(sorted(browser.cookies.items())) [('foo', 'bar'), ('sha', 'zam'), ('tweedle', 'dee'), ('va', 'voom')] >>> browser.open('http://localhost/get_cookie.html') >>> print browser.headers.get('set-cookie') None >>> print browser.contents foo: bar sha: zam tweedle: dee va: voom >>> del browser.cookies['foo'] >>> del browser.cookies['tweedle'] >>> browser.open('http://localhost/get_cookie.html') >>> print browser.contents sha: zam va: voom Headers ======= You can see the Cookies header that will be sent to the browser in the ``header`` attribute and the repr and str. >>> browser.cookies.header 'sha=zam; va=voom' >>> browser.cookies # doctest: +ELLIPSIS +NORMALIZE_WHITESPACE >>> str(browser.cookies) 'sha=zam; va=voom' Extended Mapping Interface ========================== ------------------------------------------ Read Methods: ``getinfo`` and ``iterinfo`` ------------------------------------------ ``getinfo`` ----------- The ``cookies`` mapping also has an extended interface to get and set extra information about each cookie. ``getinfo`` returns a dictionary.

If a cookie already exists for the given name, it's value will be changed; or else a new cookie will be created for the current request's domain and a path of '/', set to last for only this browser session (a "session" cookie). To create or change cookies with different additional information, use the ``create`` and ``change`` methods, respectively. Here is an example of ``create``. >>> from pytz import UTC >>> browser.cookies.create( ... 'bling', value='blang', path='/inner', ... expires=datetime.datetime(2020, 1, 1, tzinfo=UTC), ... comment='follow swallow') >>> pprint.pprint(browser.cookies.getinfo('bling')) {'comment': 'follow%20swallow', 'commenturl': None, 'domain': 'localhost.local', 'expires': datetime.datetime(2020, 1, 1, 0, 0, tzinfo=), 'name': 'bling', 'path': '/inner', 'port': None, 'secure': False, 'value': 'blang'} In these further examples of ``create``, note that the testbrowser sends all domains to Zope, and both http and https. >>> browser.open('https://dev.example.com/inner/path/get_cookie.html') >>> browser.cookies.keys() # a different domain [] >>> browser.cookies.create('tweedle', 'dee') >>> pprint.pprint(browser.cookies.getinfo('tweedle')) {'comment': None, 'commenturl': None, 'domain': 'dev.example.com', 'expires': None, 'name': 'tweedle', 'path': '/inner/path', 'port': None, 'secure': False, 'value': 'dee'} >>> browser.cookies.create( ... 'boo', 'yah', domain='.example.com', path='/inner', secure=True) >>> pprint.pprint(browser.cookies.getinfo('boo')) {'comment': None, 'commenturl': None, 'domain': '.example.com', 'expires': None, 'name': 'boo', 'path': '/inner', 'port': None, 'secure': True, 'value': 'yah'} >>> sorted(browser.cookies.keys()) ['boo', 'tweedle'] >>> browser.open('https://dev.example.com/inner/path/get_cookie.html') >>> print browser.contents boo: yah tweedle: dee >>> browser.open( # not https, so not secure, so not 'boo' ... 'http://dev.example.com/inner/path/get_cookie.html') >>> sorted(browser.cookies.keys()) ['tweedle'] >>> print browser.contents tweedle: dee >>> browser.open( # not tweedle's domain ... 'https://prod.example.com/inner/path/get_cookie.html') >>> sorted(browser.cookies.keys()) ['boo'] >>> print browser.contents boo: yah >>> browser.open( # not tweedle's domain ... 'https://example.com/inner/path/get_cookie.html') >>> sorted(browser.cookies.keys()) ['boo'] >>> print browser.contents boo: yah >>> browser.open( # not tweedle's path ... 'https://dev.example.com/inner/get_cookie.html') >>> sorted(browser.cookies.keys()) ['boo'] >>> print browser.contents boo: yah Masking by Path --------------- The API allows creation of cookies that mask existing cookies, but it does not allow creating a cookie that will be immediately masked upon creation. Having multiple cookies with the same name for a given URL is rare, and is a pathological case for using a mapping API to work with cookies, but it is supported to some degree, as demonstrated below. Note that the Cookie RFCs (2109, 2965) specify that all matching cookies be sent to the server, but with an ordering so that more specific paths come first. We also prefer more specific domains, though the RFCs state that the ordering of cookies with the same path is indeterminate. The best-matching cookie is the one that the mapping API uses. Also note that ports, as sent by RFC 2965's Cookie2 and Set-Cookie2 headers, are parsed and stored by this API but are not used for filtering as of this writing. This is an example of making one cookie that masks another because of path. First, unless you pass an explicit path, you will be modifying the existing cookie. >>> browser.open('https://dev.example.com/inner/path/get_cookie.html') >>> print browser.contents boo: yah tweedle: dee >>> browser.cookies.getinfo('boo')['path'] '/inner' >>> browser.cookies['boo'] = 'hoo' >>> browser.cookies.getinfo('boo')['path'] '/inner' >>> browser.cookies.getinfo('boo')['secure'] True Now we mask the cookie, using the path. >>> browser.cookies.create('boo', 'boo', path='/inner/path') >>> browser.cookies['boo'] 'boo' >>> browser.cookies.getinfo('boo')['path'] '/inner/path' >>> browser.cookies.getinfo('boo')['secure'] False >>> browser.cookies['boo'] 'boo' >>> sorted(browser.cookies.keys()) ['boo', 'tweedle'] To identify the additional cookies, you can change the URL... >>> extra_cookies = browser.cookies.forURL( ... 'https://dev.example.com/inner/get_cookie.html') >>> extra_cookies['boo'] 'hoo' >>> extra_cookies.getinfo('boo')['path'] '/inner' >>> extra_cookies.getinfo('boo')['secure'] True ...or use ``iterinfo`` and pass in a name. >>> pprint.pprint(list(browser.cookies.iterinfo('boo'))) [{'comment': None, 'commenturl': None, 'domain': 'dev.example.com', 'expires': None, 'name': 'boo', 'path': '/inner/path', 'port': None, 'secure': False, 'value': 'boo'}, {'comment': None, 'commenturl': None, 'domain': '.example.com', 'expires': None, 'name': 'boo', 'path': '/inner', 'port': None, 'secure': True, 'value': 'hoo'}] An odd situation in this case is that deleting a cookie can sometimes reveal another one. >>> browser.open('https://dev.example.com/inner/path/get_cookie.html') >>> browser.cookies['boo'] 'boo' >>> del browser.cookies['boo'] >>> browser.cookies['boo'] 'hoo' Creating a cookie that will be immediately masked within the current url is not allowed. >>> browser.cookies.getinfo('tweedle')['path'] '/inner/path' >>> browser.cookies.create('tweedle', 'dum', path='/inner') ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ValueError: cannot set a cookie that will be hidden by another cookie for this url (https://dev.example.com/inner/path/get_cookie.html) >>> browser.cookies['tweedle'] 'dee' Masking by Domain ----------------- All of the same behavior is also true for domains. The only difference is a theoretical one: while the behavior of masking cookies via paths is defined by the relevant IRCs, it is not defined for domains. Here, we simply follow a "best match" policy. We initialize by setting some cookies for example.org. >>> browser.open('https://dev.example.org/get_cookie.html') >>> browser.cookies.keys() # a different domain [] >>> browser.cookies.create('tweedle', 'dee') >>> browser.cookies.create('boo', 'yah', domain='example.org', ... secure=True) Before we look at the examples, note that the default behavior of the cookies is to be liberal in the matching of domains. >>> browser.cookies.strict_domain_policy False According to the RFCs, a domain of 'example.com' can only be set implicitly from the server, and implies an exact match, so example.com URLs will get the cookie, but not *.example.com (i.e., dev.example.com). Real browsers vary in their behavior in this regard. The cookies collection, by default, has a looser interpretation of this, such that domains are always interpreted as effectively beginning with a ".", so dev.example.com will include a cookie from the "example.com" domain filter as if it were a ".example.com" filter. Here's an example. If we go to dev.example.org, we should only see the "tweedle" cookie if we are using strict rules. But right now we are using loose rules, so 'boo' is around too. >>> browser.open('https://dev.example.org/get_cookie.html') >>> sorted(browser.cookies) ['boo', 'tweedle'] >>> print browser.contents boo: yah tweedle: dee If we set strict_domain_policy to True, then only tweedle is included. >>> browser.cookies.strict_domain_policy = True >>> sorted(browser.cookies) ['tweedle'] >>> browser.open('https://dev.example.org/get_cookie.html') >>> print browser.contents tweedle: dee If we set the "boo" domain to ".example.org" (as it would be set under the more recent Cookie RFC if a server sent the value) then maybe we get the "boo" value again. >>> browser.cookies.forURL('https://example.org').change( ... 'boo', domain=".example.org") Traceback (most recent call last): ... ValueError: policy does not allow this cookie Whoa! Why couldn't we do that? Well, the strict_domain_policy affects what cookies we can set also. With strict rules, ".example.org" can only be set by "*.example.org" domains, *not* example.org itself. OK, we'll create a new cookie then. >>> browser.cookies.forURL('https://snoo.example.org').create( ... 'snoo', 'kums', domain=".example.org") >>> sorted(browser.cookies) ['snoo', 'tweedle'] >>> browser.open('https://dev.example.org/get_cookie.html') >>> print browser.contents snoo: kums tweedle: dee Let's set things back to the way they were. >>> del browser.cookies['snoo'] >>> browser.cookies.strict_domain_policy = False >>> browser.open('https://dev.example.org/get_cookie.html') >>> sorted(browser.cookies) ['boo', 'tweedle'] >>> print browser.contents boo: yah tweedle: dee Now back to the the examples of masking by domain. First, unless you pass an explicit domain, you will be modifying the existing cookie. >>> browser.cookies.getinfo('boo')['domain'] 'example.org' >>> browser.cookies['boo'] = 'hoo' >>> browser.cookies.getinfo('boo')['domain'] 'example.org' >>> browser.cookies.getinfo('boo')['secure'] True Now we mask the cookie, using the domain. >>> browser.cookies.create('boo', 'boo', domain='dev.example.org') >>> browser.cookies['boo'] 'boo' >>> browser.cookies.getinfo('boo')['domain'] 'dev.example.org' >>> browser.cookies.getinfo('boo')['secure'] False >>> browser.cookies['boo'] 'boo' >>> sorted(browser.cookies.keys()) ['boo', 'tweedle'] To identify the additional cookies, you can change the URL... >>> extra_cookies = browser.cookies.forURL( ... 'https://example.org/get_cookie.html') >>> extra_cookies['boo'] 'hoo' >>> extra_cookies.getinfo('boo')['domain'] 'example.org' >>> extra_cookies.getinfo('boo')['secure'] True ...or use ``iterinfo`` and pass in a name. >>> pprint.pprint(list(browser.cookies.iterinfo('boo'))) [{'comment': None, 'commenturl': None, 'domain': 'dev.example.org', 'expires': None, 'name': 'boo', 'path': '/', 'port': None, 'secure': False, 'value': 'boo'}, {'comment': None, 'commenturl': None, 'domain': 'example.org', 'expires': None, 'name': 'boo', 'path': '/', 'port': None, 'secure': True, 'value': 'hoo'}] An odd situation in this case is that deleting a cookie can sometimes reveal another one. >>> browser.open('https://dev.example.org/get_cookie.html') >>> browser.cookies['boo'] 'boo' >>> del browser.cookies['boo'] >>> browser.cookies['boo'] 'hoo' Setting a cookie with a foreign domain from the current URL is not allowed (use forURL to get around this). >>> browser.cookies.create('tweedle', 'dum', domain='locahost.local') Traceback (most recent call last): ... ValueError: current url must match given domain >>> browser.cookies['tweedle'] 'dee' Setting a cookie that will be immediately masked within the current url is also not allowed. >>> browser.cookies.getinfo('tweedle')['domain'] 'dev.example.org' >>> browser.cookies.create('tweedle', 'dum', domain='.example.org') ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ValueError: cannot set a cookie that will be hidden by another cookie for this url (https://dev.example.org/get_cookie.html) >>> browser.cookies['tweedle'] 'dee' ``change`` ---------- So far all of our examples in this section have centered on ``create``. ``change`` allows making changes to existing cookies. Changing expiration is a good example. >>> browser.open("http://localhost/@@/testbrowser/cookies.html") >>> browser.cookies['foo'] = 'bar' >>> browser.cookies.change('foo', expires=datetime.datetime(2021, 1, 1)) >>> browser.cookies.getinfo('foo')['expires'] datetime.datetime(2021, 1, 1, 0, 0, tzinfo=) That's the main story. Now here are some edge cases. >>> browser.cookies.change( ...

This is to prevent hard-to- diagnose intermittent errors when one header or the other wins. >>> browser.cookies['boo'] = 'yah' >>> browser.addHeader('Cookie', 'gee=gaw') Traceback (most recent call last): ...

Unicode URLs ============ Unicode URLs or headers cause the entire constructed request to be unicode, and (as of Python 2.4.4) Cookie.SimpleCookie checks the type of the input against type(""), so it handles the value inappropriately, causing exceptions that ended with:: File "/home/benji/Python-2.4.4/lib/python2.4/Cookie.py", line 623, in load self.update(rawdata) ValueError: dictionary update sequence element #0 has length 1; 2 is required As a work-around, unicode strings passed to Browser.open() are now converted to ASCII before being passed on, as well as the key and value passed to Browser.addHeader(). The tests below failed before the change was put in place. >>> from zope.testbrowser.testing import Browser >>> browser = Browser() >>> browser.addHeader('Cookie', 'test') >>> browser.open(u'http://localhost/@@/testbrowser/simple.html') >>> from zope.testbrowser.testing import Browser >>> browser = Browser() >>> browser.addHeader(u'Cookie', 'test') >>> browser.open('http://localhost/@@/testbrowser/simple.html') Spaces in URL ============= When URLs have spaces in them, they're handled correctly (before the bug was fixed, you'd get "ValueError: too many values to unpack"): >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.getLink('Spaces in the URL').click() .goBack() Truncation ==================== The .goBack() method used to truncate the .contents. >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> actual_length = len(browser.contents) >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.goBack() >>> len(browser.contents) == actual_length True Labeled Radio Buttons ===================== The .getControl() method was sometimes unable to find radio buttons by label. >>> # import mechanize._form; mechanize._form._show_debug_messages() >>> browser.open('http://localhost/@@/testbrowser/radio.html') >>> browser.getControl('One').optionValue '1' >>> browser.getControl('Two').optionValue '2' >>> browser.getControl('Three').optionValue '3' Fragment URLs ============= Earlier versions of mechanize used to incorrectly follow links containing fragments. We upgraded our dependency to a newer version of mechanize and make sure this regression doesn't come back: >>> browser.open('http://localhost/@@/testbrowser/fragment.html#asdf') >>> browser.url 'http://localhost/@@/testbrowser/fragment.html#asdf' >>> browser.getLink('Follow me') >>> browser.getLink('Follow me').click() Textareas with HTML/XML ======================= >>> browser.open('http://localhost/@@/testbrowser/textarea.html') >>> browser.getControl('Text Area').value '\r\n \r\n &\r\n' .click() with non-200 status ============================ The problem was that with the below controls testbrowser forgot to do after-processing after an exception in mechanize. That means ``_stop_timer()`` and ``_changed()`` were not executed if an exception was raised. Not calling ``_changed()`` resulted in not refreshing ``contents``. The ``contents`` property gets cached on any first access and should be reset on any navigation. The problem is that e.g. a simple 403 status raises an exception. This is how it works with a simple open(): >>> browser.handleErrors=False >>> browser.open('http://localhost/set_status.html') >>> print browser.contents Everything fine >>> browser.open('http://localhost/set_status.html?status=403') Traceback (most recent call last): ... HTTPError: HTTP Error 403: Forbidden >>> print browser.contents Just set a status of 403 These are the various controls: A link: >>> browser.open('http://localhost/@@/testbrowser/status_lead.html') >>> print browser.contents ... >>> browser.getLink('403').click() Traceback (most recent call last): ... HTTPError: HTTP Error 403: Forbidden >>> print browser.contents Just set a status of 403 A submit button: >>> browser.open('http://localhost/@@/testbrowser/status_lead.html') >>> print browser.contents ... >>> browser.getControl(name='status').value = '404' >>> browser.getControl('Submit This').click() Traceback (most recent call last): ...

WSGI Test Browser ~~~~~~~~~~~~~~~~~ There is also a special version of the ``Browser`` class which uses `wsgi_intercept`_ and can be used to do functional testing of WSGI applications, it can be imported from ``zope.testbrowser.wsgi``: >>> from zope.testbrowser.wsgi import Browser >>> browser = Browser() .. _`wsgi_intercept`: http://pypi.python.org/pypi/wsgi_intercept To use this browser you have to: * use the `wsgi` extra of the ``zope.testbrowser`` egg, * write a subclass of ``zope.testbrowser.wsgi.Layer`` and override the ``make_wsgi_app`` method, * use an instance of the class as the test layer of your test. Example: >>> import zope.testbrowser.wsgi >>> class SimpleLayer(zope.testbrowser.wsgi.Layer): ... def make_wsgi_app(self): ... return simple_app Where ``simple_app`` is the callable of your WSGI application. Zope 3 Test Browser ~~~~~~~~~~~~~~~~~~~ There is also a special version of the ``Browser`` class used to do functional testing of Zope 3 applications, it can be imported from ``zope.testbrowser.testing``: >>> from zope.testbrowser.testing import Browser >>> browser = Browser() Bowser Usage ------------ All browsers are used the same way. An initial page to load can be passed to the ``Browser`` constructor: >>> browser = Browser('http://localhost/@@/testbrowser/simple.html') >>> browser.url 'http://localhost/@@/testbrowser/simple.html' The browser can send arbitrary headers; this is helpful for setting the "Authorization" header or a language value, so that your tests format values the way you expect in your tests, if you rely on zope.i18n locale-based formatting or a similar approach. >>> browser.addHeader('Authorization', 'Basic mgr:mgrpw') >>> browser.addHeader('Accept-Language', 'en-US') An existing browser instance can also `open` web pages: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.url 'http://localhost/@@/testbrowser/simple.html' Once you have opened a web page initially, best practice for writing testbrowser doctests suggests using 'click' to navigate further (as discussed below), except in unusual circumstances. The test browser complies with the IBrowser interface; see ``zope.testbrowser.interfaces`` for full details on the interface. >>> from zope.testbrowser import interfaces >>> from zope.interface.verify import verifyObject >>> verifyObject(interfaces.IBrowser, browser) True Page Contents ------------- The contents of the current page are available: >>> print browser.contents Simple Page

Simple Page

Making assertions about page contents is easy. >>> '

Simple Page

' in browser.contents True Utilizing the doctest facilities, it also possible to do: >>> browser.contents '...

Simple Page

...' Note: Unfortunately, ellipsis (...) cannot be used at the beginning of the output (this is a limitation of doctest). Checking for HTML ----------------- Not all URLs return HTML. Of course our simple page does: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.isHtml True But if we load an image (or other binary file), we do not get HTML: >>> browser.open('http://localhost/@@/testbrowser/zope3logo.gif') >>> browser.isHtml False HTML Page Title ---------------- Another useful helper property is the title: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.title 'Simple Page' If a page does not provide a title, it is simply ``None``: >>> browser.open('http://localhost/@@/testbrowser/notitle.html') >>> browser.title However, if the output is not HTML, then an error will occur trying to access the title: >>> browser.open('http://localhost/@@/testbrowser/zope3logo.gif') >>> browser.title Traceback (most recent call last): ... BrowserStateError: not viewing HTML Headers ------- As you can see, the `contents` of the browser does not return any HTTP headers. The headers are accessible via a separate attribute, which is an ``httplib.HTTPMessage`` instance (httplib is a part of Python's standard library): >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.headers The headers can be accessed as a string: >>> print browser.headers Status: 200 OK Content-Length: 123 Content-Type: text/html;charset=utf-8 X-Powered-By: Zope (www.zope.org), Python (www.python.org) Or as a mapping: >>> browser.headers['content-type'] 'text/html;charset=utf-8' Cookies ------- When a Set-Cookie header is available, it can be found in the headers, as seen above. Here, we use a view that will make the server set cookies with the values we provide. >>> browser.open('http://localhost/set_cookie.html?name=foo&value=bar') >>> browser.headers['set-cookie'].replace(';', '') 'foo=bar' It is also available in the browser's ``cookies`` attribute. This is an extended mapping interface that allows getting, setting, and deleting the cookies that the browser is remembering *for the current url*. Here are a few examples. >>> browser.cookies['foo'] 'bar' >>> browser.cookies.keys() ['foo'] >>> browser.cookies.values() ['bar'] >>> browser.cookies.items() [('foo', 'bar')] >>> 'foo' in browser.cookies True >>> 'bar' in browser.cookies False >>> len(browser.cookies) 1 >>> print(dict(browser.cookies)) {'foo': 'bar'} >>> browser.cookies['sha'] = 'zam' >>> len(browser.cookies) 2 >>> sorted(browser.cookies.items()) [('foo', 'bar'), ('sha', 'zam')] >>> browser.open('http://localhost/get_cookie.html') >>> print browser.headers.get('set-cookie') None >>> print browser.contents # server got the cookie change foo: bar sha: zam >>> sorted(browser.cookies.items()) [('foo', 'bar'), ('sha', 'zam')] >>> browser.cookies.clearAll() >>> len(browser.cookies) 0 Many more examples, and a discussion of the additional methods available, can be found in cookies.txt. Navigation and Link Objects --------------------------- If you want to simulate clicking on a link, get the link and `click` on it. In the `navigate.html` file there are several links set up to demonstrate the capabilities of the link objects and their `click` method. The simplest way to get a link is via the anchor text. In other words the text you would see in a browser (text and url searches are substring searches): >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...Link Text...' >>> link = browser.getLink('Link Text') >>> link Link objects comply with the ILink interface. >>> verifyObject(interfaces.ILink, link) True Links expose several attributes for easy access. >>> link.text 'Link Text' >>> link.tag # links can also be image maps. 'a' >>> link.url # it's normalized 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text' >>> link.attrs {'href': 'navigate.html?message=By+Link+Text'} Links can be "clicked" and the browser will navigate to the referenced URL. >>> link.click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text' >>> browser.contents '...Message: By Link Text...' When finding a link by its text, whitespace is normalized. >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...> Link Text \n with Whitespace\tNormalization (and parens) >> link = browser.getLink('Link Text with Whitespace Normalization ' ... '(and parens)') >>> link >>> link.text 'Link Text with Whitespace Normalization (and parens)' >>> link.click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text+with+Normalization' >>> browser.contents '...Message: By Link Text with Normalization...' When a link text matches more than one link, by default the first one is chosen. You can, however, specify the index of the link and thus retrieve a later matching link: >>> browser.getLink('Link Text') >>> browser.getLink('Link Text', index=1) Note that clicking a link object after its browser page has expired will generate an error. >>> link.click() Traceback (most recent call last): ... ExpiredError You can also find the link by its URL, >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...Using the URL...' >>> browser.getLink(url='?message=By+URL').click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+URL' >>> browser.contents '...Message: By URL...' or its id: >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...By Anchor Id...' >>> browser.getLink(id='anchorid').click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Id' >>> browser.contents '...Message: By Id...' You thought we were done here? Not so quickly. The `getLink` method also supports image maps, though not by specifying the coordinates, but using the area's id: >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> link = browser.getLink(id='zope3') >>> link.tag 'area' >>> link.click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=Zope+3+Name' >>> browser.contents '...Message: Zope 3 Name...' Getting a nonexistent link raises an exception. >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.getLink('This does not exist') Traceback (most recent call last): ... LinkNotFoundError A convenience method is provided to follow links; this uses the same arguments as `getLink`, but clicks on the link instead of returning the link object. >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...Link Text...' >>> browser.follow('Link Text') >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text' >>> browser.contents '...Message: By Link Text...' >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.follow(url='?message=By+URL') >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+URL' >>> browser.contents '...Message: By URL...' >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.follow(id='zope3') >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=Zope+3+Name' >>> browser.contents '...Message: Zope 3 Name...' Attempting to follow links that don't exist raises the same exception as asking for the link object: >>> browser.follow('This does not exist') Traceback (most recent call last): ... LinkNotFoundError Other Navigation ---------------- Like in any normal browser, you can reload a page: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.url 'http://localhost/@@/testbrowser/simple.html' >>> browser.reload() >>> browser.url 'http://localhost/@@/testbrowser/simple.html' You can also go back: >>> browser.open('http://localhost/@@/testbrowser/notitle.html') >>> browser.url 'http://localhost/@@/testbrowser/notitle.html' >>> browser.goBack() >>> browser.url 'http://localhost/@@/testbrowser/simple.html' Controls -------- One of the most important features of the browser is the ability to inspect and fill in values for the controls of input forms. To do so, let's first open a page that has a bunch of controls: >>> browser.open('http://localhost/@@/testbrowser/controls.html') Obtaining a Control ~~~~~~~~~~~~~~~~~~~ You look up browser controls with the 'getControl' method. The default first argument is 'label', and looks up the form on the basis of any associated label. >>> control = browser.getControl('Text Control') >>> control >>> browser.getControl(label='Text Control') # equivalent If you request a control that doesn't exist, the code raises a LookupError: >>> browser.getControl('Does Not Exist') Traceback (most recent call last): ... LookupError: label 'Does Not Exist' If you request a control with an ambiguous lookup, the code raises an AmbiguityError. >>> browser.getControl('Ambiguous Control') Traceback (most recent call last): ... AmbiguityError: label 'Ambiguous Control' This is also true if an option in a control is ambiguous in relation to the control itself. >>> browser.getControl('Sub-control Ambiguity') Traceback (most recent call last): ... AmbiguityError: label 'Sub-control Ambiguity' Ambiguous controls may be specified using an index value. We use the control's value attribute to show the two controls; this attribute is properly introduced below. >>> browser.getControl('Ambiguous Control', index=0) >>> browser.getControl('Ambiguous Control', index=0).value 'First' >>> browser.getControl('Ambiguous Control', index=1).value 'Second' >>> browser.getControl('Sub-control Ambiguity', index=0) >>> browser.getControl('Sub-control Ambiguity', index=1).optionValue 'ambiguous' Label searches are against stripped, whitespace-normalized, no-tag versions of the text. Text applied to searches is also stripped and whitespace normalized. The search finds results if the text search finds the whole words of your text in a label. Thus, for instance, a search for 'Add' will match the label 'Add a Client' but not 'Address'. Case is honored. >>> browser.getControl('Label Needs Whitespace Normalization') >>> browser.getControl('label needs whitespace normalization') Traceback (most recent call last): ... LookupError: label 'label needs whitespace normalization' >>> browser.getControl(' Label Needs Whitespace ') >>> browser.getControl('Whitespace') >>> browser.getControl('hitespace') Traceback (most recent call last): ... LookupError: label 'hitespace' >>> browser.getControl('[non word characters should not confuse]') Multiple labels can refer to the same control (simply because that is possible in the HTML 4.0 spec). >>> browser.getControl('Multiple labels really') >>> browser.getControl('really are possible') >>> browser.getControl('really') # OK: ambiguous labels, but not ambiguous control A label can be connected with a control using the 'for' attribute and also by containing a control. >>> browser.getControl( ... 'Labels can be connected by containing their respective fields') Get also accepts one other search argument, 'name'. Only one of 'label' and 'name' may be used at a time. The 'name' keyword searches form field names. >>> browser.getControl(name='text-value') >>> browser.getControl(name='ambiguous-control-name') Traceback (most recent call last): ... AmbiguityError: name 'ambiguous-control-name' >>> browser.getControl(name='does-not-exist') Traceback (most recent call last): ... LookupError: name 'does-not-exist' >>> browser.getControl(name='ambiguous-control-name', index=1).value 'Second' Combining 'label' and 'name' raises a ValueError, as does supplying neither of them. >>> browser.getControl(label='Ambiguous Control', name='ambiguous-control-name') Traceback (most recent call last): ... ValueError: Supply one and only one of "label" and "name" as arguments >>> browser.getControl() Traceback (most recent call last): ... ValueError: Supply one and only one of "label" and "name" as arguments Radio and checkbox fields are unusual in that their labels and names may point to different objects: names point to logical collections of radio buttons or checkboxes, but labels may only be used for individual choices within the logical collection. This means that obtaining a radio button by label gets a different object than obtaining the radio collection by name. Select options may also be searched by label. >>> browser.getControl(name='radio-value') >>> browser.getControl('Zwei') >>> browser.getControl('One') >>> browser.getControl('Tres') Characteristics of controls and subcontrols are discussed below. Control Objects ~~~~~~~~~~~~~~~ Controls provide IControl. >>> ctrl = browser.getControl('Text Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True They have several useful attributes: - the name as which the control is known to the form: >>> ctrl.name 'text-value' - the value of the control, which may also be set: >>> ctrl.value 'Some Text' >>> ctrl.value = 'More Text' >>> ctrl.value 'More Text' - the type of the control: >>> ctrl.type 'text' - a flag describing whether the control is disabled: >>> ctrl.disabled False - and a flag to tell us whether the control can have multiple values: >>> ctrl.multiple False Additionally, controllers for select, radio, and checkbox provide IListControl. These fields have four other attributes and an additional method: >>> ctrl = browser.getControl('Multiple Select Control') >>> ctrl >>> ctrl.disabled False >>> ctrl.multiple True >>> verifyObject(interfaces.IListControl, ctrl) True - 'options' lists all available value options. >>> ctrl.options ['1', '2', '3'] - 'displayOptions' lists all available options by label. The 'label' attribute on an option has precedence over its contents, which is why our last option is 'Third' in the display. >>> ctrl.displayOptions ['Un', 'Deux', 'Third'] - 'displayValue' lets you get and set the displayed values of the control of the select box, rather than the actual values. >>> ctrl.value [] >>> ctrl.displayValue [] >>> ctrl.displayValue = ['Un', 'Deux'] >>> ctrl.displayValue ['Un', 'Deux'] >>> ctrl.value ['1', '2'] - 'controls' gives you a list of the subcontrol objects in the control (subcontrols are discussed below). >>> ctrl.controls [, , ] - The 'getControl' method lets you get subcontrols by their label or their value. >>> ctrl.getControl('Un') >>> ctrl.getControl('Deux') >>> ctrl.getControl('Trois') # label attribute >>> ctrl.getControl('Third') # contents >>> browser.getControl('Third') # ambiguous in the browser, so useful Traceback (most recent call last): ... AmbiguityError: label 'Third' Finally, submit controls provide ISubmitControl, and image controls provide IImageSubmitControl, which extents ISubmitControl. These both simply add a 'click' method. For image submit controls, you may also provide a coordinates argument, which is a tuple of (x, y). These submit the forms, and are demonstrated below as we examine each control individually. ItemControl Objects ~~~~~~~~~~~~~~~~~~~ As introduced briefly above, using labels to obtain elements of a logical radio button or checkbox collection returns item controls, which are parents. Manipulating the value of these controls affects the parent control. >>> browser.getControl(name='radio-value').value ['2'] >>> browser.getControl('Zwei').optionValue # read-only. '2' >>> browser.getControl('Zwei').selected True >>> verifyObject(interfaces.IItemControl, browser.getControl('Zwei')) True >>> browser.getControl('Ein').selected = True >>> browser.getControl('Ein').selected True >>> browser.getControl('Zwei').selected False >>> browser.getControl(name='radio-value').value ['1'] >>> browser.getControl('Ein').selected = False >>> browser.getControl(name='radio-value').value [] >>> browser.getControl('Zwei').selected = True Checkbox collections behave similarly, as shown below. Controls with subcontrols-- Various Controls ~~~~~~~~~~~~~~~~ The various types of controls are demonstrated here. - Text Control The text control we already introduced above. - Password Control >>> ctrl = browser.getControl('Password Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value 'Password' >>> ctrl.value = 'pass now' >>> ctrl.value 'pass now' >>> ctrl.disabled False >>> ctrl.multiple False - Hidden Control >>> ctrl = browser.getControl(name='hidden-value') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value 'Hidden' >>> ctrl.value = 'More Hidden' >>> ctrl.disabled False >>> ctrl.multiple False - Text Area Control >>> ctrl = browser.getControl('Text Area Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value ' Text inside\n area!\n ' >>> ctrl.value = 'A lot of\n text.' >>> ctrl.disabled False >>> ctrl.multiple False - File Control File controls are used when a form has a file-upload field. To specify data, call the add_file method, passing: - A file-like object - a content type, and - a file name >>> ctrl = browser.getControl('File Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value is None True >>> import cStringIO >>> ctrl.add_file(cStringIO.StringIO('File contents'), ... 'text/plain', 'test.txt') The file control (like the other controls) also knows if it is disabled or if it can have multiple values. >>> ctrl.disabled False >>> ctrl.multiple False - Selection Control (Single-Valued) >>> ctrl = browser.getControl('Single Select Control') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value ['1'] >>> ctrl.value = ['2'] >>> ctrl.disabled False >>> ctrl.multiple False >>> ctrl.options ['1', '2', '3'] >>> ctrl.displayOptions ['Uno', 'Dos', 'Third'] >>> ctrl.displayValue ['Dos'] >>> ctrl.displayValue = ['Tres'] >>> ctrl.displayValue ['Third'] >>> ctrl.displayValue = ['Dos'] >>> ctrl.displayValue ['Dos'] >>> ctrl.displayValue = ['Third'] >>> ctrl.displayValue ['Third'] >>> ctrl.value ['3'] - Selection Control (Multi-Valued) This was already demonstrated in the introduction to control objects above. - Checkbox Control (Single-Valued; Unvalued) >>> ctrl = browser.getControl(name='single-unvalued-checkbox-value') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value True >>> ctrl.value = False >>> ctrl.disabled False >>> ctrl.multiple True >>> ctrl.options [True] >>> ctrl.displayOptions ['Single Unvalued Checkbox'] >>> ctrl.displayValue [] >>> verifyObject( ... interfaces.IItemControl, ... browser.getControl('Single Unvalued Checkbox')) True >>> browser.getControl('Single Unvalued Checkbox').optionValue 'on' >>> browser.getControl('Single Unvalued Checkbox').selected False >>> ctrl.displayValue = ['Single Unvalued Checkbox'] >>> ctrl.displayValue ['Single Unvalued Checkbox'] >>> browser.getControl('Single Unvalued Checkbox').selected True >>> browser.getControl('Single Unvalued Checkbox').selected = False >>> browser.getControl('Single Unvalued Checkbox').selected False >>> ctrl.displayValue [] >>> browser.getControl( ... name='single-disabled-unvalued-checkbox-value').disabled True - Checkbox Control (Single-Valued, Valued) >>> ctrl = browser.getControl(name='single-valued-checkbox-value') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value ['1'] >>> ctrl.value = [] >>> ctrl.disabled False >>> ctrl.multiple True >>> ctrl.options ['1'] >>> ctrl.displayOptions ['Single Valued Checkbox'] >>> ctrl.displayValue [] >>> verifyObject( ... interfaces.IItemControl, ... browser.getControl('Single Valued Checkbox')) True >>> browser.getControl('Single Valued Checkbox').selected False >>> browser.getControl('Single Valued Checkbox').optionValue '1' >>> ctrl.displayValue = ['Single Valued Checkbox'] >>> ctrl.displayValue ['Single Valued Checkbox'] >>> browser.getControl('Single Valued Checkbox').selected True >>> browser.getControl('Single Valued Checkbox').selected = False >>> browser.getControl('Single Valued Checkbox').selected False >>> ctrl.displayValue [] - Checkbox Control (Multi-Valued) >>> ctrl = browser.getControl(name='multi-checkbox-value') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value ['1', '3'] >>> ctrl.value = ['1', '2'] >>> ctrl.disabled False >>> ctrl.multiple True >>> ctrl.options ['1', '2', '3'] >>> ctrl.displayOptions ['One', 'Two', 'Three'] >>> ctrl.displayValue ['One', 'Two'] >>> ctrl.displayValue = ['Two'] >>> ctrl.value ['2'] >>> browser.getControl('Two').optionValue '2' >>> browser.getControl('Two').selected True >>> verifyObject(interfaces.IItemControl, browser.getControl('Two')) True >>> browser.getControl('Three').selected = True >>> browser.getControl('Three').selected True >>> browser.getControl('Two').selected True >>> ctrl.value ['2', '3'] >>> browser.getControl('Two').selected = False >>> ctrl.value ['3'] >>> browser.getControl('Three').selected = False >>> ctrl.value [] - Radio Control This is how you get a radio button based control: >>> ctrl = browser.getControl(name='radio-value') This shows the existing value of the control, as it was in the HTML received from the server: >>> ctrl.value ['2'] We can then unselect it: >>> ctrl.value = [] >>> ctrl.value [] We can also reselect it: >>> ctrl.value = ['2'] >>> ctrl.value ['2'] displayValue shows the text the user would see next to the control: >>> ctrl.displayValue ['Zwei'] This is just unit testing: >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.disabled False >>> ctrl.multiple False >>> ctrl.options ['1', '2', '3'] >>> ctrl.displayOptions ['Ein', 'Zwei', 'Drei'] >>> ctrl.displayValue = ['Ein'] >>> ctrl.value ['1'] >>> ctrl.displayValue ['Ein'] The radio control subcontrols were illustrated above. - Image Control >>> ctrl = browser.getControl(name='image-value') >>> ctrl >>> verifyObject(interfaces.IImageSubmitControl, ctrl) True >>> ctrl.value '' >>> ctrl.disabled False >>> ctrl.multiple False - Submit Control >>> ctrl = browser.getControl(name='submit-value') >>> ctrl >>> browser.getControl('Submit This') # value of submit button is a label >>> browser.getControl('Standard Submit Control') # label tag is legal >>> browser.getControl('Submit') # multiple labels, but same control >>> verifyObject(interfaces.ISubmitControl, ctrl) True >>> ctrl.value 'Submit This' >>> ctrl.disabled False >>> ctrl.multiple False Using Submitting Controls ~~~~~~~~~~~~~~~~~~~~~~~~~ Both the submit and image type should be clickable and submit the form: >>> browser.getControl('Text Control').value = 'Other Text' >>> browser.getControl('Submit').click() >>> print browser.contents ... Other Text ... Submit This ... Note that if you click a submit object after the associated page has expired, you will get an error. >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> ctrl = browser.getControl('Submit') >>> ctrl.click() >>> ctrl.click() Traceback (most recent call last): ... ExpiredError All the above also holds true for the image control: >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> browser.getControl('Text Control').value = 'Other Text' >>> browser.getControl(name='image-value').click() >>> print browser.contents ... Other Text ... 1 1 ... >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> ctrl = browser.getControl(name='image-value') >>> ctrl.click() >>> ctrl.click() Traceback (most recent call last): ... ExpiredError But when sending an image, you can also specify the coordinate you clicked: >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> browser.getControl(name='image-value').click((50,25)) >>> print browser.contents ... 50 25 ... Forms ----- Because pages can have multiple forms with like-named controls, it is sometimes necessary to access forms by name or id. The browser's `forms` attribute can be used to do so. The key value is the form's name or id. If more than one form has the same name or id, the first one will be returned. >>> browser.open('http://localhost/@@/testbrowser/forms.html') >>> form = browser.getForm(name='one') Form instances conform to the IForm interface. >>> verifyObject(interfaces.IForm, form) True The form exposes several attributes related to forms: - The name of the form: >>> form.name 'one' - The id of the form: >>> form.id '1' - The action (target URL) when the form is submitted: >>> form.action 'http://localhost/@@/testbrowser/forms.html' - The method (HTTP verb) used to transmit the form data: >>> form.method 'GET' Besides those attributes, you have also a couple of methods. Like for the browser, you can get control objects, but limited to the current form... >>> form.getControl(name='text-value') ...and submit the form. >>> form.submit('Submit') >>> print browser.contents ... First Text ... Submitting also works without specifying a control, as shown below, which is it's primary reason for existing in competition with the control submission discussed above. Now let me show you briefly that looking up forms is sometimes important. In the `forms.html` template, we have four forms all having a text control named `text-value`. Now, if I use the browser's `get` method, >>> browser.getControl(name='text-value') Traceback (most recent call last): ... AmbiguityError: name 'text-value' >>> browser.getControl('Text Control') Traceback (most recent call last): ... AmbiguityError: label 'Text Control' I'll always get an ambiguous form field. I can use the index argument, or with the `getForm` method I can disambiguate by searching only within a given form: >>> form = browser.getForm('2') >>> form.getControl(name='text-value').value 'Second Text' >>> form.submit('Submit') >>> browser.contents '...Second Text...' >>> form = browser.getForm('2') >>> form.getControl('Submit').click() >>> browser.contents '...Second Text...' >>> browser.getForm('3').getControl('Text Control').value 'Third Text' The last form on the page does not have a name, an id, or a submit button. Working with it is still easy, thanks to a index attribute that guarantees order. (Forms without submit buttons are sometimes useful for JavaScript.) >>> form = browser.getForm(index=3) >>> form.submit() >>> browser.contents '...Fourth Text...Submitted without the submit button....' If a form is requested that does not exists, an exception will be raised. >>> form = browser.getForm('does-not-exist') Traceback (most recent call last): LookupError If the HTML page contains only one form, no arguments to `getForm` are needed: >>> oneform = Browser() >>> oneform.open('http://localhost/@@/testbrowser/oneform.html') >>> form = oneform.getForm() If the HTML page contains more than one form, `index` is needed to disambiguate if no other arguments are provided: >>> browser.getForm() Traceback (most recent call last): ValueError: if no other arguments are given, index is required. Submitting a posts body directly -------------------------------- In addition to the open method, zope.testbrowser.testing.Browser has a ``post`` method that allows a request body to be supplied. This method is particularly helpful when testing Ajax methods. Let's visit a page that echos it's request: >>> browser.open('http://localhost/@@echo.html') >>> print browser.contents, HTTP_USER_AGENT: Python-urllib/2.4 HTTP_CONNECTION: close HTTP_COOKIE: REMOTE_ADDR: 127.0.0.1 HTTP_ACCEPT_LANGUAGE: en-US REQUEST_METHOD: GET HTTP_HOST: localhost PATH_INFO: /@@echo.html SERVER_PROTOCOL: HTTP/1.1 QUERY_STRING: Body: '' Now, we'll try a post. The post method takes a URL, a data string, and an optional content type. If we just pass a string, then a URL-encoded query string is assumed: >>> browser.post('http://localhost/@@echo.html', 'x=1&y=2') >>> print browser.contents, CONTENT_LENGTH: 7 HTTP_USER_AGENT: Python-urllib/2.4 HTTP_CONNECTION: close HTTP_COOKIE: REMOTE_ADDR: 127.0.0.1 HTTP_ACCEPT_LANGUAGE: en-US y: 2 REQUEST_METHOD: POST HTTP_HOST: localhost PATH_INFO: /@@echo.html CONTENT_TYPE: application/x-www-form-urlencoded SERVER_PROTOCOL: HTTP/1.1 QUERY_STRING: x: 1 Body: '' The body is empty because it is consumed to get form data. We can pass a content-type explicitly: >>> browser.post('http://localhost/@@echo.html', ... '{"x":1,"y":2}', 'application/x-javascript') >>> print browser.contents, CONTENT_LENGTH: 13 HTTP_USER_AGENT: Python-urllib/2.4 HTTP_CONNECTION: close HTTP_COOKIE: REMOTE_ADDR: 127.0.0.1 HTTP_ACCEPT_LANGUAGE: en-US REQUEST_METHOD: POST HTTP_HOST: localhost PATH_INFO: /@@echo.html CONTENT_TYPE: application/x-javascript SERVER_PROTOCOL: HTTP/1.1 Body: '{"x":1,"y":2}' Here, the body is left in place because it isn't form data. Performance Testing ------------------- Browser objects keep up with how much time each request takes. This can be used to ensure a particular request's performance is within a tolerable range. Be very careful using raw seconds, cross-machine differences can be huge, pystones is usually a better choice. >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.lastRequestSeconds < 10 # really big number for safety True >>> browser.lastRequestPystones < 10000 # really big number for safety True Handling Errors when using Zope 3's Publisher --------------------------------------------- A very useful feature of the publisher is the automatic graceful handling of application errors, such as invalid URLs: >>> browser.open('http://localhost/invalid') Traceback (most recent call last): ... HTTPError: HTTP Error 404: Not Found Note that the above error was thrown by ``mechanize`` and not by the publisher. For debugging purposes, however, it can be very useful to see the original exception caused by the application. In those cases you can set the ``handleErrors`` property of the browser to ``False``. It is defaulted to ``True``: >>> browser.handleErrors True So when we tell the publisher not to handle the errors, >>> browser.handleErrors = False we get a different, Zope internal error: >>> browser.open('http://localhost/invalid') Traceback (most recent call last): ... NotFound: Object: , name: u'invalid' NB: Setting the handleErrors attribute to False will only change anything if the http server you're testing is using Zope 3's publisher or can otherwise respond appropriately to an 'X-zope-handle-errors' header in requests. When the testbrowser is raising HttpErrors, the errors still hit the test. Sometimes we don't want that to happen, in situations where there are edge cases that will cause the error to be predictably but infrequently raised. Time is a primary cause of this. To get around this, one can set the raiseHttpErrors to False. >>> browser.handleErrors = True >>> browser.raiseHttpErrors = False This will cause HttpErrors not to propagate. >>> browser.open('http://localhost/invalid') The headers are still there, though. >>> '404 Not Found' in str(browser.headers) True If we don't handle the errors, and allow internal ones to propagate, however, this flag doesn't affect things. >>> browser.handleErrors = False >>> browser.open('http://localhost/invalid') Traceback (most recent call last): ... NotFound: Object: , name: u'invalid' >>> browser.raiseHttpErrors = True Hand-Holding ------------ Instances of the various objects ensure that users don't set incorrect instance attributes accidentally. >>> browser.nonexistant = None Traceback (most recent call last): ... AttributeError: 'Browser' object has no attribute 'nonexistant' >>> form.nonexistant = None Traceback (most recent call last): ...

It is used in Zope, but it's not Zope specific at all. For instance, it can be used to test or otherwise interact with any web site. ====================== Detailed Documentation ====================== Different Browsers ------------------ HTTP Browser ~~~~~~~~~~~~ The ``zope.testbrowser.browser`` module exposes a ``Browser`` class that simulates a web browser similar to Mozilla Firefox or IE. >>> from zope.testbrowser.browser import Browser >>> browser = Browser() This version of the browser object can be used to access any web site just as you would do using a normal web browser. WSGI Test Browser ~~~~~~~~~~~~~~~~~ There is also a special version of the ``Browser`` class which uses `wsgi_intercept`_ and can be used to do functional testing of WSGI applications, it can be imported from ``zope.testbrowser.wsgi``: >>> from zope.testbrowser.wsgi import Browser >>> browser = Browser() .. _`wsgi_intercept`: http://pypi.python.org/pypi/wsgi_intercept To use this browser you have to: * use the `wsgi` extra of the ``zope.testbrowser`` egg, * write a subclass of ``zope.testbrowser.wsgi.Layer`` and override the ``make_wsgi_app`` method, * use an instance of the class as the test layer of your test. Example: >>> import zope.testbrowser.wsgi >>> class SimpleLayer(zope.testbrowser.wsgi.Layer): ... def make_wsgi_app(self): ... return simple_app Where ``simple_app`` is the callable of your WSGI application. Zope 3 Test Browser ~~~~~~~~~~~~~~~~~~~ There is also a special version of the ``Browser`` class used to do functional testing of Zope 3 applications, it can be imported from ``zope.testbrowser.testing``: >>> from zope.testbrowser.testing import Browser >>> browser = Browser() Bowser Usage ------------ All browsers are used the same way. An initial page to load can be passed to the ``Browser`` constructor: >>> browser = Browser('http://localhost/@@/testbrowser/simple.html') >>> browser.url 'http://localhost/@@/testbrowser/simple.html' The browser can send arbitrary headers; this is helpful for setting the "Authorization" header or a language value, so that your tests format values the way you expect in your tests, if you rely on zope.i18n locale-based formatting or a similar approach. >>> browser.addHeader('Authorization', 'Basic mgr:mgrpw') >>> browser.addHeader('Accept-Language', 'en-US') An existing browser instance can also `open` web pages: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.url 'http://localhost/@@/testbrowser/simple.html' Once you have opened a web page initially, best practice for writing testbrowser doctests suggests using 'click' to navigate further (as discussed below), except in unusual circumstances. The test browser complies with the IBrowser interface; see ``zope.testbrowser.interfaces`` for full details on the interface. >>> from zope.testbrowser import interfaces >>> from zope.interface.verify import verifyObject >>> verifyObject(interfaces.IBrowser, browser) True Page Contents ------------- The contents of the current page are available: >>> print browser.contents Simple Page

Simple Page

Making assertions about page contents is easy. >>> '

Simple Page

' in browser.contents True Utilizing the doctest facilities, it also possible to do: >>> browser.contents '...

Simple Page

...' Note: Unfortunately, ellipsis (...) cannot be used at the beginning of the output (this is a limitation of doctest). Checking for HTML ----------------- Not all URLs return HTML. Of course our simple page does: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.isHtml True But if we load an image (or other binary file), we do not get HTML: >>> browser.open('http://localhost/@@/testbrowser/zope3logo.gif') >>> browser.isHtml False HTML Page Title ---------------- Another useful helper property is the title: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.title 'Simple Page' If a page does not provide a title, it is simply ``None``: >>> browser.open('http://localhost/@@/testbrowser/notitle.html') >>> browser.title However, if the output is not HTML, then an error will occur trying to access the title: >>> browser.open('http://localhost/@@/testbrowser/zope3logo.gif') >>> browser.title Traceback (most recent call last): ... BrowserStateError: not viewing HTML Headers ------- As you can see, the `contents` of the browser does not return any HTTP headers. The headers are accessible via a separate attribute, which is an ``httplib.HTTPMessage`` instance (httplib is a part of Python's standard library): >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.headers The headers can be accessed as a string: >>> print browser.headers Status: 200 OK Content-Length: 123 Content-Type: text/html;charset=utf-8 X-Powered-By: Zope (www.zope.org), Python (www.python.org) Or as a mapping: >>> browser.headers['content-type'] 'text/html;charset=utf-8' Cookies ------- When a Set-Cookie header is available, it can be found in the headers, as seen above. Here, we use a view that will make the server set cookies with the values we provide. >>> browser.open('http://localhost/set_cookie.html?name=foo&value=bar') >>> browser.headers['set-cookie'].replace(';', '') 'foo=bar' It is also available in the browser's ``cookies`` attribute. This is an extended mapping interface that allows getting, setting, and deleting the cookies that the browser is remembering *for the current url*. Here are a few examples. >>> browser.cookies['foo'] 'bar' >>> browser.cookies.keys() ['foo'] >>> browser.cookies.values() ['bar'] >>> browser.cookies.items() [('foo', 'bar')] >>> 'foo' in browser.cookies True >>> 'bar' in browser.cookies False >>> len(browser.cookies) 1 >>> print(dict(browser.cookies)) {'foo': 'bar'} >>> browser.cookies['sha'] = 'zam' >>> len(browser.cookies) 2 >>> sorted(browser.cookies.items()) [('foo', 'bar'), ('sha', 'zam')] >>> browser.open('http://localhost/get_cookie.html') >>> print browser.headers.get('set-cookie') None >>> print browser.contents # server got the cookie change foo: bar sha: zam >>> sorted(browser.cookies.items()) [('foo', 'bar'), ('sha', 'zam')] >>> browser.cookies.clearAll() >>> len(browser.cookies) 0 Many more examples, and a discussion of the additional methods available, can be found in cookies.txt. Navigation and Link Objects --------------------------- If you want to simulate clicking on a link, get the link and `click` on it. In the `navigate.html` file there are several links set up to demonstrate the capabilities of the link objects and their `click` method. The simplest way to get a link is via the anchor text. In other words the text you would see in a browser (text and url searches are substring searches): >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...Link Text...' >>> link = browser.getLink('Link Text') >>> link Link objects comply with the ILink interface. >>> verifyObject(interfaces.ILink, link) True Links expose several attributes for easy access. >>> link.text 'Link Text' >>> link.tag # links can also be image maps. 'a' >>> link.url # it's normalized 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text' >>> link.attrs {'href': 'navigate.html?message=By+Link+Text'} Links can be "clicked" and the browser will navigate to the referenced URL. >>> link.click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text' >>> browser.contents '...Message: By Link Text...' When finding a link by its text, whitespace is normalized. >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...> Link Text \n with Whitespace\tNormalization (and parens) >> link = browser.getLink('Link Text with Whitespace Normalization ' ... '(and parens)') >>> link >>> link.text 'Link Text with Whitespace Normalization (and parens)' >>> link.click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text+with+Normalization' >>> browser.contents '...Message: By Link Text with Normalization...' When a link text matches more than one link, by default the first one is chosen. You can, however, specify the index of the link and thus retrieve a later matching link: >>> browser.getLink('Link Text') >>> browser.getLink('Link Text', index=1) Note that clicking a link object after its browser page has expired will generate an error. >>> link.click() Traceback (most recent call last): ... ExpiredError You can also find the link by its URL, >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...Using the URL...' >>> browser.getLink(url='?message=By+URL').click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+URL' >>> browser.contents '...Message: By URL...' or its id: >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...By Anchor Id...' >>> browser.getLink(id='anchorid').click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Id' >>> browser.contents '...Message: By Id...' You thought we were done here? Not so quickly. The `getLink` method also supports image maps, though not by specifying the coordinates, but using the area's id: >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> link = browser.getLink(id='zope3') >>> link.tag 'area' >>> link.click() >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=Zope+3+Name' >>> browser.contents '...Message: Zope 3 Name...' Getting a nonexistent link raises an exception. >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.getLink('This does not exist') Traceback (most recent call last): ... LinkNotFoundError A convenience method is provided to follow links; this uses the same arguments as `getLink`, but clicks on the link instead of returning the link object. >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.contents '...Link Text...' >>> browser.follow('Link Text') >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+Link+Text' >>> browser.contents '...Message: By Link Text...' >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.follow(url='?message=By+URL') >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=By+URL' >>> browser.contents '...Message: By URL...' >>> browser.open('http://localhost/@@/testbrowser/navigate.html') >>> browser.follow(id='zope3') >>> browser.url 'http://localhost/@@/testbrowser/navigate.html?message=Zope+3+Name' >>> browser.contents '...Message: Zope 3 Name...' Attempting to follow links that don't exist raises the same exception as asking for the link object: >>> browser.follow('This does not exist') Traceback (most recent call last): ... LinkNotFoundError Other Navigation ---------------- Like in any normal browser, you can reload a page: >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.url 'http://localhost/@@/testbrowser/simple.html' >>> browser.reload() >>> browser.url 'http://localhost/@@/testbrowser/simple.html' You can also go back: >>> browser.open('http://localhost/@@/testbrowser/notitle.html') >>> browser.url 'http://localhost/@@/testbrowser/notitle.html' >>> browser.goBack() >>> browser.url 'http://localhost/@@/testbrowser/simple.html' Controls -------- One of the most important features of the browser is the ability to inspect and fill in values for the controls of input forms. To do so, let's first open a page that has a bunch of controls: >>> browser.open('http://localhost/@@/testbrowser/controls.html') Obtaining a Control ~~~~~~~~~~~~~~~~~~~ You look up browser controls with the 'getControl' method. The default first argument is 'label', and looks up the form on the basis of any associated label. >>> control = browser.getControl('Text Control') >>> control >>> browser.getControl(label='Text Control') # equivalent If you request a control that doesn't exist, the code raises a LookupError: >>> browser.getControl('Does Not Exist') Traceback (most recent call last): ... LookupError: label 'Does Not Exist' If you request a control with an ambiguous lookup, the code raises an AmbiguityError. >>> browser.getControl('Ambiguous Control') Traceback (most recent call last): ... AmbiguityError: label 'Ambiguous Control' This is also true if an option in a control is ambiguous in relation to the control itself. >>> browser.getControl('Sub-control Ambiguity') Traceback (most recent call last): ... AmbiguityError: label 'Sub-control Ambiguity' Ambiguous controls may be specified using an index value. We use the control's value attribute to show the two controls; this attribute is properly introduced below. >>> browser.getControl('Ambiguous Control', index=0) >>> browser.getControl('Ambiguous Control', index=0).value 'First' >>> browser.getControl('Ambiguous Control', index=1).value 'Second' >>> browser.getControl('Sub-control Ambiguity', index=0) >>> browser.getControl('Sub-control Ambiguity', index=1).optionValue 'ambiguous' Label searches are against stripped, whitespace-normalized, no-tag versions of the text. Text applied to searches is also stripped and whitespace normalized. The search finds results if the text search finds the whole words of your text in a label. Thus, for instance, a search for 'Add' will match the label 'Add a Client' but not 'Address'. Case is honored. >>> browser.getControl('Label Needs Whitespace Normalization') >>> browser.getControl('label needs whitespace normalization') Traceback (most recent call last): ... LookupError: label 'label needs whitespace normalization' >>> browser.getControl(' Label Needs Whitespace ') >>> browser.getControl('Whitespace') >>> browser.getControl('hitespace') Traceback (most recent call last): ... LookupError: label 'hitespace' >>> browser.getControl('[non word characters should not confuse]') Multiple labels can refer to the same control (simply because that is possible in the HTML 4.0 spec). >>> browser.getControl('Multiple labels really') >>> browser.getControl('really are possible') >>> browser.getControl('really') # OK: ambiguous labels, but not ambiguous control A label can be connected with a control using the 'for' attribute and also by containing a control. >>> browser.getControl( ... 'Labels can be connected by containing their respective fields') Get also accepts one other search argument, 'name'. Only one of 'label' and 'name' may be used at a time. The 'name' keyword searches form field names. >>> browser.getControl(name='text-value') >>> browser.getControl(name='ambiguous-control-name') Traceback (most recent call last): ... AmbiguityError: name 'ambiguous-control-name' >>> browser.getControl(name='does-not-exist') Traceback (most recent call last): ... LookupError: name 'does-not-exist' >>> browser.getControl(name='ambiguous-control-name', index=1).value 'Second' Combining 'label' and 'name' raises a ValueError, as does supplying neither of them. >>> browser.getControl(label='Ambiguous Control', name='ambiguous-control-name') Traceback (most recent call last): ... ValueError: Supply one and only one of "label" and "name" as arguments >>> browser.getControl() Traceback (most recent call last): ... ValueError: Supply one and only one of "label" and "name" as arguments Radio and checkbox fields are unusual in that their labels and names may point to different objects: names point to logical collections of radio buttons or checkboxes, but labels may only be used for individual choices within the logical collection. This means that obtaining a radio button by label gets a different object than obtaining the radio collection by name. Select options may also be searched by label. >>> browser.getControl(name='radio-value') >>> browser.getControl('Zwei') >>> browser.getControl('One') >>> browser.getControl('Tres') Characteristics of controls and subcontrols are discussed below. Control Objects ~~~~~~~~~~~~~~~ Controls provide IControl. >>> ctrl = browser.getControl('Text Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True They have several useful attributes: - the name as which the control is known to the form: >>> ctrl.name 'text-value' - the value of the control, which may also be set: >>> ctrl.value 'Some Text' >>> ctrl.value = 'More Text' >>> ctrl.value 'More Text' - the type of the control: >>> ctrl.type 'text' - a flag describing whether the control is disabled: >>> ctrl.disabled False - and a flag to tell us whether the control can have multiple values: >>> ctrl.multiple False Additionally, controllers for select, radio, and checkbox provide IListControl. These fields have four other attributes and an additional method: >>> ctrl = browser.getControl('Multiple Select Control') >>> ctrl >>> ctrl.disabled False >>> ctrl.multiple True >>> verifyObject(interfaces.IListControl, ctrl) True - 'options' lists all available value options. >>> ctrl.options ['1', '2', '3'] - 'displayOptions' lists all available options by label. The 'label' attribute on an option has precedence over its contents, which is why our last option is 'Third' in the display. >>> ctrl.displayOptions ['Un', 'Deux', 'Third'] - 'displayValue' lets you get and set the displayed values of the control of the select box, rather than the actual values. >>> ctrl.value [] >>> ctrl.displayValue [] >>> ctrl.displayValue = ['Un', 'Deux'] >>> ctrl.displayValue ['Un', 'Deux'] >>> ctrl.value ['1', '2'] - 'controls' gives you a list of the subcontrol objects in the control (subcontrols are discussed below). >>> ctrl.controls [, , ] - The 'getControl' method lets you get subcontrols by their label or their value. >>> ctrl.getControl('Un') >>> ctrl.getControl('Deux') >>> ctrl.getControl('Trois') # label attribute >>> ctrl.getControl('Third') # contents >>> browser.getControl('Third') # ambiguous in the browser, so useful Traceback (most recent call last): ... AmbiguityError: label 'Third' Finally, submit controls provide ISubmitControl, and image controls provide IImageSubmitControl, which extents ISubmitControl. These both simply add a 'click' method. For image submit controls, you may also provide a coordinates argument, which is a tuple of (x, y). These submit the forms, and are demonstrated below as we examine each control individually. ItemControl Objects ~~~~~~~~~~~~~~~~~~~ As introduced briefly above, using labels to obtain elements of a logical radio button or checkbox collection returns item controls, which are parents. Manipulating the value of these controls affects the parent control. >>> browser.getControl(name='radio-value').value ['2'] >>> browser.getControl('Zwei').optionValue # read-only. '2' >>> browser.getControl('Zwei').selected True >>> verifyObject(interfaces.IItemControl, browser.getControl('Zwei')) True >>> browser.getControl('Ein').selected = True >>> browser.getControl('Ein').selected True >>> browser.getControl('Zwei').selected False >>> browser.getControl(name='radio-value').value ['1'] >>> browser.getControl('Ein').selected = False >>> browser.getControl(name='radio-value').value [] >>> browser.getControl('Zwei').selected = True Checkbox collections behave similarly, as shown below. Controls with subcontrols-- Various Controls ~~~~~~~~~~~~~~~~ The various types of controls are demonstrated here. - Text Control The text control we already introduced above. - Password Control >>> ctrl = browser.getControl('Password Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value 'Password' >>> ctrl.value = 'pass now' >>> ctrl.value 'pass now' >>> ctrl.disabled False >>> ctrl.multiple False - Hidden Control >>> ctrl = browser.getControl(name='hidden-value') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value 'Hidden' >>> ctrl.value = 'More Hidden' >>> ctrl.disabled False >>> ctrl.multiple False - Text Area Control >>> ctrl = browser.getControl('Text Area Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value ' Text inside\n area!\n ' >>> ctrl.value = 'A lot of\n text.' >>> ctrl.disabled False >>> ctrl.multiple False - File Control File controls are used when a form has a file-upload field. To specify data, call the add_file method, passing: - A file-like object - a content type, and - a file name >>> ctrl = browser.getControl('File Control') >>> ctrl >>> verifyObject(interfaces.IControl, ctrl) True >>> ctrl.value is None True >>> import cStringIO >>> ctrl.add_file(cStringIO.StringIO('File contents'), ... 'text/plain', 'test.txt') The file control (like the other controls) also knows if it is disabled or if it can have multiple values. >>> ctrl.disabled False >>> ctrl.multiple False - Selection Control (Single-Valued) >>> ctrl = browser.getControl('Single Select Control') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value ['1'] >>> ctrl.value = ['2'] >>> ctrl.disabled False >>> ctrl.multiple False >>> ctrl.options ['1', '2', '3'] >>> ctrl.displayOptions ['Uno', 'Dos', 'Third'] >>> ctrl.displayValue ['Dos'] >>> ctrl.displayValue = ['Tres'] >>> ctrl.displayValue ['Third'] >>> ctrl.displayValue = ['Dos'] >>> ctrl.displayValue ['Dos'] >>> ctrl.displayValue = ['Third'] >>> ctrl.displayValue ['Third'] >>> ctrl.value ['3'] - Selection Control (Multi-Valued) This was already demonstrated in the introduction to control objects above. - Checkbox Control (Single-Valued; Unvalued) >>> ctrl = browser.getControl(name='single-unvalued-checkbox-value') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value True >>> ctrl.value = False >>> ctrl.disabled False >>> ctrl.multiple True >>> ctrl.options [True] >>> ctrl.displayOptions ['Single Unvalued Checkbox'] >>> ctrl.displayValue [] >>> verifyObject( ... interfaces.IItemControl, ... browser.getControl('Single Unvalued Checkbox')) True >>> browser.getControl('Single Unvalued Checkbox').optionValue 'on' >>> browser.getControl('Single Unvalued Checkbox').selected False >>> ctrl.displayValue = ['Single Unvalued Checkbox'] >>> ctrl.displayValue ['Single Unvalued Checkbox'] >>> browser.getControl('Single Unvalued Checkbox').selected True >>> browser.getControl('Single Unvalued Checkbox').selected = False >>> browser.getControl('Single Unvalued Checkbox').selected False >>> ctrl.displayValue [] >>> browser.getControl( ... name='single-disabled-unvalued-checkbox-value').disabled True - Checkbox Control (Single-Valued, Valued) >>> ctrl = browser.getControl(name='single-valued-checkbox-value') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value ['1'] >>> ctrl.value = [] >>> ctrl.disabled False >>> ctrl.multiple True >>> ctrl.options ['1'] >>> ctrl.displayOptions ['Single Valued Checkbox'] >>> ctrl.displayValue [] >>> verifyObject( ... interfaces.IItemControl, ... browser.getControl('Single Valued Checkbox')) True >>> browser.getControl('Single Valued Checkbox').selected False >>> browser.getControl('Single Valued Checkbox').optionValue '1' >>> ctrl.displayValue = ['Single Valued Checkbox'] >>> ctrl.displayValue ['Single Valued Checkbox'] >>> browser.getControl('Single Valued Checkbox').selected True >>> browser.getControl('Single Valued Checkbox').selected = False >>> browser.getControl('Single Valued Checkbox').selected False >>> ctrl.displayValue [] - Checkbox Control (Multi-Valued) >>> ctrl = browser.getControl(name='multi-checkbox-value') >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.value ['1', '3'] >>> ctrl.value = ['1', '2'] >>> ctrl.disabled False >>> ctrl.multiple True >>> ctrl.options ['1', '2', '3'] >>> ctrl.displayOptions ['One', 'Two', 'Three'] >>> ctrl.displayValue ['One', 'Two'] >>> ctrl.displayValue = ['Two'] >>> ctrl.value ['2'] >>> browser.getControl('Two').optionValue '2' >>> browser.getControl('Two').selected True >>> verifyObject(interfaces.IItemControl, browser.getControl('Two')) True >>> browser.getControl('Three').selected = True >>> browser.getControl('Three').selected True >>> browser.getControl('Two').selected True >>> ctrl.value ['2', '3'] >>> browser.getControl('Two').selected = False >>> ctrl.value ['3'] >>> browser.getControl('Three').selected = False >>> ctrl.value [] - Radio Control This is how you get a radio button based control: >>> ctrl = browser.getControl(name='radio-value') This shows the existing value of the control, as it was in the HTML received from the server: >>> ctrl.value ['2'] We can then unselect it: >>> ctrl.value = [] >>> ctrl.value [] We can also reselect it: >>> ctrl.value = ['2'] >>> ctrl.value ['2'] displayValue shows the text the user would see next to the control: >>> ctrl.displayValue ['Zwei'] This is just unit testing: >>> ctrl >>> verifyObject(interfaces.IListControl, ctrl) True >>> ctrl.disabled False >>> ctrl.multiple False >>> ctrl.options ['1', '2', '3'] >>> ctrl.displayOptions ['Ein', 'Zwei', 'Drei'] >>> ctrl.displayValue = ['Ein'] >>> ctrl.value ['1'] >>> ctrl.displayValue ['Ein'] The radio control subcontrols were illustrated above. - Image Control >>> ctrl = browser.getControl(name='image-value') >>> ctrl >>> verifyObject(interfaces.IImageSubmitControl, ctrl) True >>> ctrl.value '' >>> ctrl.disabled False >>> ctrl.multiple False - Submit Control >>> ctrl = browser.getControl(name='submit-value') >>> ctrl >>> browser.getControl('Submit This') # value of submit button is a label >>> browser.getControl('Standard Submit Control') # label tag is legal >>> browser.getControl('Submit') # multiple labels, but same control >>> verifyObject(interfaces.ISubmitControl, ctrl) True >>> ctrl.value 'Submit This' >>> ctrl.disabled False >>> ctrl.multiple False Using Submitting Controls ~~~~~~~~~~~~~~~~~~~~~~~~~ Both the submit and image type should be clickable and submit the form: >>> browser.getControl('Text Control').value = 'Other Text' >>> browser.getControl('Submit').click() >>> print browser.contents ... Other Text ... Submit This ... Note that if you click a submit object after the associated page has expired, you will get an error. >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> ctrl = browser.getControl('Submit') >>> ctrl.click() >>> ctrl.click() Traceback (most recent call last): ... ExpiredError All the above also holds true for the image control: >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> browser.getControl('Text Control').value = 'Other Text' >>> browser.getControl(name='image-value').click() >>> print browser.contents ... Other Text ... 1 1 ... >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> ctrl = browser.getControl(name='image-value') >>> ctrl.click() >>> ctrl.click() Traceback (most recent call last): ... ExpiredError But when sending an image, you can also specify the coordinate you clicked: >>> browser.open('http://localhost/@@/testbrowser/controls.html') >>> browser.getControl(name='image-value').click((50,25)) >>> print browser.contents ... 50 25 ... Forms ----- Because pages can have multiple forms with like-named controls, it is sometimes necessary to access forms by name or id. The browser's `forms` attribute can be used to do so. The key value is the form's name or id. If more than one form has the same name or id, the first one will be returned. >>> browser.open('http://localhost/@@/testbrowser/forms.html') >>> form = browser.getForm(name='one') Form instances conform to the IForm interface. >>> verifyObject(interfaces.IForm, form) True The form exposes several attributes related to forms: - The name of the form: >>> form.name 'one' - The id of the form: >>> form.id '1' - The action (target URL) when the form is submitted: >>> form.action 'http://localhost/@@/testbrowser/forms.html' - The method (HTTP verb) used to transmit the form data: >>> form.method 'GET' Besides those attributes, you have also a couple of methods. Like for the browser, you can get control objects, but limited to the current form... >>> form.getControl(name='text-value') ...and submit the form. >>> form.submit('Submit') >>> print browser.contents ... First Text ... Submitting also works without specifying a control, as shown below, which is it's primary reason for existing in competition with the control submission discussed above. Now let me show you briefly that looking up forms is sometimes important. In the `forms.html` template, we have four forms all having a text control named `text-value`. Now, if I use the browser's `get` method, >>> browser.getControl(name='text-value') Traceback (most recent call last): ... AmbiguityError: name 'text-value' >>> browser.getControl('Text Control') Traceback (most recent call last): ... AmbiguityError: label 'Text Control' I'll always get an ambiguous form field. I can use the index argument, or with the `getForm` method I can disambiguate by searching only within a given form: >>> form = browser.getForm('2') >>> form.getControl(name='text-value').value 'Second Text' >>> form.submit('Submit') >>> browser.contents '...Second Text...' >>> form = browser.getForm('2') >>> form.getControl('Submit').click() >>> browser.contents '...Second Text...' >>> browser.getForm('3').getControl('Text Control').value 'Third Text' The last form on the page does not have a name, an id, or a submit button. Working with it is still easy, thanks to a index attribute that guarantees order. (Forms without submit buttons are sometimes useful for JavaScript.) >>> form = browser.getForm(index=3) >>> form.submit() >>> browser.contents '...Fourth Text...Submitted without the submit button....' If a form is requested that does not exists, an exception will be raised. >>> form = browser.getForm('does-not-exist') Traceback (most recent call last): LookupError If the HTML page contains only one form, no arguments to `getForm` are needed: >>> oneform = Browser() >>> oneform.open('http://localhost/@@/testbrowser/oneform.html') >>> form = oneform.getForm() If the HTML page contains more than one form, `index` is needed to disambiguate if no other arguments are provided: >>> browser.getForm() Traceback (most recent call last): ValueError: if no other arguments are given, index is required. Submitting a posts body directly -------------------------------- In addition to the open method, zope.testbrowser.testing.Browser has a ``post`` method that allows a request body to be supplied. This method is particularly helpful when testing Ajax methods. Let's visit a page that echos it's request: >>> browser.open('http://localhost/@@echo.html') >>> print browser.contents, HTTP_USER_AGENT: Python-urllib/2.4 HTTP_CONNECTION: close HTTP_COOKIE: REMOTE_ADDR: 127.0.0.1 HTTP_ACCEPT_LANGUAGE: en-US REQUEST_METHOD: GET HTTP_HOST: localhost PATH_INFO: /@@echo.html SERVER_PROTOCOL: HTTP/1.1 QUERY_STRING: Body: '' Now, we'll try a post. The post method takes a URL, a data string, and an optional content type. If we just pass a string, then a URL-encoded query string is assumed: >>> browser.post('http://localhost/@@echo.html', 'x=1&y=2') >>> print browser.contents, CONTENT_LENGTH: 7 HTTP_USER_AGENT: Python-urllib/2.4 HTTP_CONNECTION: close HTTP_COOKIE: REMOTE_ADDR: 127.0.0.1 HTTP_ACCEPT_LANGUAGE: en-US y: 2 REQUEST_METHOD: POST HTTP_HOST: localhost PATH_INFO: /@@echo.html CONTENT_TYPE: application/x-www-form-urlencoded SERVER_PROTOCOL: HTTP/1.1 QUERY_STRING: x: 1 Body: '' The body is empty because it is consumed to get form data. We can pass a content-type explicitly: >>> browser.post('http://localhost/@@echo.html', ... '{"x":1,"y":2}', 'application/x-javascript') >>> print browser.contents, CONTENT_LENGTH: 13 HTTP_USER_AGENT: Python-urllib/2.4 HTTP_CONNECTION: close HTTP_COOKIE: REMOTE_ADDR: 127.0.0.1 HTTP_ACCEPT_LANGUAGE: en-US REQUEST_METHOD: POST HTTP_HOST: localhost PATH_INFO: /@@echo.html CONTENT_TYPE: application/x-javascript SERVER_PROTOCOL: HTTP/1.1 Body: '{"x":1,"y":2}' Here, the body is left in place because it isn't form data. Performance Testing ------------------- Browser objects keep up with how much time each request takes. This can be used to ensure a particular request's performance is within a tolerable range. Be very careful using raw seconds, cross-machine differences can be huge, pystones is usually a better choice. >>> browser.open('http://localhost/@@/testbrowser/simple.html') >>> browser.lastRequestSeconds < 10 # really big number for safety True >>> browser.lastRequestPystones < 10000 # really big number for safety True Handling Errors when using Zope 3's Publisher --------------------------------------------- A very useful feature of the publisher is the automatic graceful handling of application errors, such as invalid URLs: >>> browser.open('http://localhost/invalid') Traceback (most recent call last): ... HTTPError: HTTP Error 404: Not Found Note that the above error was thrown by ``mechanize`` and not by the publisher. For debugging purposes, however, it can be very useful to see the original exception caused by the application. In those cases you can set the ``handleErrors`` property of the browser to ``False``. It is defaulted to ``True``: >>> browser.handleErrors True So when we tell the publisher not to handle the errors, >>> browser.handleErrors = False we get a different, Zope internal error: >>> browser.open('http://localhost/invalid') Traceback (most recent call last): ... NotFound: Object: , name: u'invalid' NB: Setting the handleErrors attribute to False will only change anything if the http server you're testing is using Zope 3's publisher or can otherwise respond appropriately to an 'X-zope-handle-errors' header in requests. When the testbrowser is raising HttpErrors, the errors still hit the test. Sometimes we don't want that to happen, in situations where there are edge cases that will cause the error to be predictably but infrequently raised. Time is a primary cause of this. To get around this, one can set the raiseHttpErrors to False. >>> browser.handleErrors = True >>> browser.raiseHttpErrors = False This will cause HttpErrors not to propagate. >>> browser.open('http://localhost/invalid') The headers are still there, though. >>> '404 Not Found' in str(browser.headers) True If we don't handle the errors, and allow internal ones to propagate, however, this flag doesn't affect things. >>> browser.handleErrors = False >>> browser.open('http://localhost/invalid') Traceback (most recent call last): ... NotFound: Object: , name: u'invalid' >>> browser.raiseHttpErrors = True Hand-Holding ------------ Instances of the various objects ensure that users don't set incorrect instance attributes accidentally. >>> browser.nonexistant = None Traceback (most recent call last): ... AttributeError: 'Browser' object has no attribute 'nonexistant' >>> form.nonexistant = None Traceback (most recent call last): ... AttributeError: 'Form' object has no attribute 'nonexistant' >>> control.nonexistant = None Traceback (most recent call last): ... AttributeError: 'Control' object has no attribute 'nonexistant' >>> link.nonexistant = None Traceback (most recent call last): ... AttributeError: 'Link' object has no attribute 'nonexistant' ======= CHANGES ======= 3.11.1 (2011-01-24) ------------------- - Fixing brown bag release 3.11.0. 3.11.0 (2011-01-24) ------------------- - Added `wsgi_intercept` support (came from ``zope.app.wsgi.testlayer``). 3.10.4 (2011-01-14) ------------------- - Move the over-the-wire.txt doctest out of the TestBrowserLayer as it doesn't need or use it. - Fix test compatibility with zope.app.testing 3.8.1. 3.10.3 (2010-10-15) ------------------- - Fixed backwards compatibility with ``zope.app.wsgi.testlayer``. 3.10.2 (2010-10-15) ------------------- - Fixed Python 2.7 compatibility in Browser.handleErrors. 3.10.1 (2010-09-21) ------------------- - Fixed a bug that caused the ``Browser`` to keep it's previous ``contents`` The places are: - Link.click() - SubmitControl.click() - ImageControl.click() - Form.submit() - Also adjusted exception messages at the above places to match pre version 3.4.1 messages. 3.10.0 (2010-09-14) ------------------- - LP #98437: use mechanize's built-in ``submit()`` to submit forms, allowing mechanize to set the "Referer:" (sic) header appropriately. - Fixed tests to run with ``zope.app.testing`` 3.8 and above. 3.9.0 (2010-05-17) ------------------ - LP #568806: Update dependency ``mechanize >= 0.2.0``, which now includes the ``ClientForm`` APIs. Remove use of ``urllib2`` APIs (incompatible with ``mechanize 0.2.0``) in favor of ``mechanize`` equivalents. Thanks to John J. Lee for the patch. - Use stdlib ``doctest`` module, instead of ``zope.testing.doctest``. - **Caution:** This version is no longer fully compatible with Python 2.4: ``handleErrors = False`` no longer works. 3.8.1 (2010-04-19) ------------------ - Pinned dependency on mechanize to prevent use of the upcoming 0.2.0 release before we have time to adjust to its API changes. - LP #98396: testbrowser resolves relative URLs incorrectly. 3.8.0 (2010-03-05) ------------------ - Added ``follow`` convenience method which gets and follows a link. 3.7.0 (2009-12-17) ------------------ - Moved zope.app.testing dependency into the scope of the PublisherConnection class. Zope2 specifies its own PublisherConnection which isn't dependent on zope.app.testing. - Fixed LP #419119: return None when the browser has no contents instead of raising an exception. 3.7.0a1 (2009-08-29) -------------------- - Remove dependency on zope.app.publisher in favor of zope.browserpage, zope.browserresource and zope.ptresource. - Remove dependencies on zope.app.principalannotation and zope.securitypolicy by using the simple PermissiveSecurityPolicy. We aren't testing security in our tests. - Replaced the testing dependency on zope.app.zcmlfiles with explicit dependencies of a minimal set of packages. - Remove unneeded zope.app.authentication from ftesting.zcml. - Test dependency on zope.securitypolicy instead of its app variant. 3.6.0a2 (2009-01-31) -------------------- - Test dependency on zope.site.folder instead of zope.app.folder. - Remove useless test dependency in zope.app.component. 3.6.0a1 (2009-01-08) -------------------- - Author e-mail to zope-dev rather than zope3-dev. - New lines are no longer stripped in XML and HTML code contained in a textarea; fix requires ClientForm >= 0.2.10 (LP #268139). - Added ``cookies`` attribute to browser for easy manipulation of browser cookies. See brief example in main documentation, plus new ``cookies.txt`` documentation. 3.5.1 (2008-10-10) ------------------ - Provide a work around for a mechanize/urllib2 bug on Python 2.6 missing 'timeout' attribute on 'Request' base class. - Provide a work around for a mechanize/urllib2 bug in creating request objects that won't handle fragment URLs correctly. 3.5.0 (2008-03-30) ------------------ - Added a zope.testbrowser.testing.Browser.post method that allows tests to supply a body and a content type. This is handy for testing Ajax requests with non-form input (e.g. JSON). - Remove vendor import of mechanize. - Fix bug that caused HTTP exception tracebacks to differ between version 3.4.0 and 3.4.1. - Workaround for bug in Python Cookie.SimpleCookie when handling unicode strings. - Fix bug introduced in 3.4.1 that created incompatible tracebacks in doctests. This necessitated adding a patched mechanize to the source tree; patches have been sent to the mechanize project. - Fix https://bugs.launchpad.net/bugs/149517 by adding zope.interface and zope.schema as real dependencies - Fix browser.getLink documentation that was not updated since the last API modification. - Move tests for fixed bugs to a separate file. - Removed non-functional and undocumented code intended to help test servers using virtual hosting. 3.4.2 (2007-10-31) ------------------ - Resolve ``ZopeSecurityPolicy`` deprecation warning. 3.4.1 (2007-09-01) ------------------ * Updated to mechanize 0.1.7b and ClientForm 0.2.7. These are now pulled in via egg dependencies. * ``zope.testbrowser`` now works on Python 2.5. 3.4.0 (2007-06-04) ------------------ * Added the ability to suppress raising exceptions on HTTP errors (``raiseHttpErrors`` attribute). * Made the tests more resilient to HTTP header formatting changes with the REnormalizer. 3.4.0a1 (2007-04-22) -------------------- Initial release as a separate project, corresponds to zope.testbrowser from Zope 3.4.0a1 Platform: UNKNOWN Classifier: Environment :: Web Environment Classifier: Intended Audience :: Developers Classifier: License :: OSI Approved :: Zope Public License Classifier: Programming Language :: Python Classifier: Topic :: Software Development :: Testing Classifier: Topic :: Internet :: WWW/HTTP zope2.13-2.13.21/source/zope.testbrowser/src/zope.testbrowser.egg-info/dependency_links.txt0000644000175000017500000000000112214017652030664 0ustar arnauarnau zope2.13-2.13.21/source/zope.testbrowser/src/zope.testbrowser.egg-info/requires.txt0000644000175000017500000000055112214017652027217 0ustar arnauarnaumechanize>=0.2.0 setuptools zope.interface zope.schema pytz [test] zope.browserpage zope.browserresource zope.component zope.container zope.principalregistry zope.ptresource zope.publisher zope.security zope.site zope.traversing zope.app.appsetup zope.app.publication zope.app.testing >= 3.8.1 [zope-functional-testing] zope.app.testing [wsgi] wsgi_interceptzope2.13-2.13.21/source/zope.testbrowser/src/zope.testbrowser.egg-info/namespace_packages.txt0000644000175000017500000000000512214017652031144 0ustar arnauarnauzope zope2.13-2.13.21/source/zope.testbrowser/src/zope.testbrowser.egg-info/top_level.txt0000644000175000017500000000000512214017652027343 0ustar arnauarnauzope zope2.13-2.13.21/source/zope.testbrowser/src/zope.testbrowser.egg-info/SOURCES.txt0000644000175000017500000000277512214017652026515 0ustar arnauarnauCHANGES.txt COPYRIGHT.txt LICENSE.txt README.txt bootstrap.py buildout.cfg setup.py src/zope/__init__.py src/zope.testbrowser.egg-info/PKG-INFO src/zope.testbrowser.egg-info/SOURCES.txt src/zope.testbrowser.egg-info/dependency_links.txt src/zope.testbrowser.egg-info/namespace_packages.txt src/zope.testbrowser.egg-info/not-zip-safe src/zope.testbrowser.egg-info/requires.txt src/zope.testbrowser.egg-info/top_level.txt src/zope/testbrowser/README.txt src/zope/testbrowser/__init__.py src/zope/testbrowser/browser.py src/zope/testbrowser/cookies.py src/zope/testbrowser/cookies.txt src/zope/testbrowser/fixed-bugs.txt src/zope/testbrowser/interfaces.py src/zope/testbrowser/over_the_wire.txt src/zope/testbrowser/testing.py src/zope/testbrowser/wsgi.py src/zope/testbrowser/ftests/__init__.py src/zope/testbrowser/ftests/controls.html src/zope/testbrowser/ftests/cookies.html src/zope/testbrowser/ftests/forms.html src/zope/testbrowser/ftests/fragment.html src/zope/testbrowser/ftests/ftesting.zcml src/zope/testbrowser/ftests/navigate.html src/zope/testbrowser/ftests/notitle.html src/zope/testbrowser/ftests/oneform.html src/zope/testbrowser/ftests/radio.html src/zope/testbrowser/ftests/simple.html src/zope/testbrowser/ftests/status_lead.html src/zope/testbrowser/ftests/textarea.html src/zope/testbrowser/ftests/zope3logo.gif src/zope/testbrowser/tests/__init__.py src/zope/testbrowser/tests/helper.py src/zope/testbrowser/tests/test_browser.py src/zope/testbrowser/tests/test_doctests.py src/zope/testbrowser/tests/test_wsgi.pyzope2.13-2.13.21/source/zope.testbrowser/src/zope.testbrowser.egg-info/not-zip-safe0000644000175000017500000000000112214017652027044 0ustar arnauarnau zope2.13-2.13.21/source/zope.exceptions/0000755000175000017500000000000012214017562016574 5ustar arnauarnauzope2.13-2.13.21/source/zope.exceptions/setup.py0000644000175000017500000000551112214017562020310 0ustar arnauarnau############################################################################## # # Copyright (c) 2006 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

I removed it. 3.5.2 (2008-04-30) ------------------ - Updated CHANGES.txt. 3.5.1 (2008-04-28) ------------------ - Reverted changes in 3.5.0. 3.5.0 ----- - Added the capability for exceptions to be formatted line-by-line. Unfortunately, also introduced a bug cause each line of the exception to be its own log message. 3.4.0 (2007-10-02) ------------------ - Updated package meta-data. 3.4.0b2 (2007-08-14) -------------------- - Removed superfluous dependency on ``zope.deprecation``. 3.4.0b1 (2007-07-09) -------------------- - Corresponds to the version of the ``zope.exceptions`` package shipped as part of the Zope 3.4.0b1 release. 3.2.0 (2006-01-05) ------------------ - Corresponds to the version of the ``zope.exceptions`` package shipped as part of the Zope 3.2.0 release. - Deprecated the ``INotFoundError`` interface and the corresponding ``NotFoundError`` exception class, in favor of "standard" exceptions ``AttributeError``, ``KeyError``). The deprecated items will be removed in Zope 3.3. 3.0.0 (2004-11-07) ------------------ - Corresponds to the version of the zope.exceptions package shipped as part of the Zope X3.0.0 release.

Detailed Documentation ---------------------- ========================== Zope configuration system ========================== The zope configuration system provides an extensible system for supporting variouse kinds of configurations. It is based on the idea of configuration directives. Users of the configuration system provide configuration directives in some language that express configuration choices. The intent is that the language be pluggable. An XML language is provided by default. Configuration is performed in three stages. In the first stage, directives are processed to compute configuration actions. Configuration actions consist of: - A discriminator - A callable - Positional arguments - Keyword arguments The actions are essentially delayed function calls. Two or more actions conflict if they have the same discriminator. The configuration system has rules for resolving conflicts. If conflicts cannot be resolved, an error will result. Conflict resolution typically discards all but one of the conflicting actions, so that the remaining action of the originally-conflicting actions no longer conflicts. Non-conflicting actions are executed in the order that they were created by passing the positional and non-positional arguments to the action callable. The system is extensible. There is a meta-configuration language for defining configuration directives. A directive is defined by providing meta data about the directive and handler code to process the directive. There are four kinds of directives: - Simple directives compute configuration actions. Their handlers are typically functions that take a context and zero or more keyword arguments and return a sequence of configuration actions. To learn how to create simple directives, see `tests/test_simple.py`. - Grouping directives collect information to be used by nested directives. They are called with a context object which they adapt to some interface that extends IConfigurationContext. To learn how to create grouping directives, look at the documentation in zopeconfigure.py, which provides the implementation of the zope `configure` directive. Other directives can be nested in grouping directives. To learn how to implement nested directives, look at the documentation in `tests/test_nested.py`. - Complex directives are directives that have subdirectives. Subdirectives have handlers that are simply methods of complex directives. Complex diretives are handled by factories, typically classes, that create objects that have methods for handling subdirectives. These objects also have __call__ methods that are called when processing of subdirectives is finished. Complex directives only exist to support old directive handlers. They will probably be deprecated in the future. - Subdirectives are nested in complex directives. They are like simple directives except that they hane handlers that are complex directive methods. Subdirectives, like complex directives only exist to support old directive handlers. They will probably be deprecated in the future. ======= Changes ======= 3.7.4 (2011-04-03) ------------------ - Test fixes for Windows. 3.7.3 (2011-03-11) ------------------ - Correctly locate packages with a __path__ attribute but no __file__ attribute (such as namespace packages installed with setup.py install --single-version-externally-managed). - Allow "info" and "includepath" to be passed optionally to context.action. 3.7.2 (2010-04-30) ------------------ - Prefer the standard libraries doctest module over zope.testing.doctest. 3.7.1 (2010-01-05) ------------------ - Jython support: use ``__builtin__`` module import rather than assuming ``__builtins__`` is available. - Jython support: deal with the fact that the Jython SAX parser returns attribute sets that have an empty string indicating no namespace instead of ``None``. - Allow ``setup.py test`` to run at least a subset of the tests that would be run when using the zope testrunner: ``setup.py test`` runs 53 tests, while ``bin/test`` runs 156. 3.7.0 (2009-12-22) ------------------ - Adjust testing output to newer zope.schema. - Prefer zope.testing.doctest over doctestunit. 3.6.0 (2009-04-01) ------------------ - Removed dependency of `zope.deprecation` package. - Don't suppress deprecation warnings any more in 'zope.configuration' package level. This makes it more likely other packages will generate deprecation warnings now, which will allow us to remove more outdated ones. - Don't fail when zope.testing is not installed. - Added missing ``processFile`` method to ``IConfigurationContext``. It is already implemented in the mix-in class, ``zope.configuration.config.ConfigurationContext``, and used by implementations of ``include`` and ``exclude`` directives. 3.5.0 (2009-02-26) ------------------ - Added the ``exclude`` directive to standard directives. It was previously available via ``zc.configuration`` package and now it's merged into ``zope.configuration``. - Changed package's mailing list address to zope-dev at zope.org, change "cheeseshop" to "pypi" in the package's url. 3.4.1 (2008-12-11) ------------------ - Use built-in 'set' type, rather than importin the 'sets' module, which is deprecated in Python 2.6. - Added support to bootstrap on Jython. 3.4.0 (2007-10-02) ------------------ - Initial release as a standalone package.

It is based on the idea of configuration directives. Users of the configuration system provide configuration directives in some language that express configuration choices. The intent is that the language be pluggable. An XML language is provided by default. zope2.13-2.13.21/source/zope.configuration/setup.cfg0000644000175000017500000000007312214017543021102 0ustar arnauarnau[egg_info] tag_build = tag_date = 0 tag_svn_revision = 0 zope2.13-2.13.21/source/zope.configuration/COPYRIGHT.txt0000644000175000017500000000004012214017543021364 0ustar arnauarnauZope Foundation and Contributorszope2.13-2.13.21/source/zope.configuration/buildout.cfg0000644000175000017500000000030212214017543021564 0ustar arnauarnau[buildout] develop = . parts = test python [test] recipe = zc.recipe.testrunner eggs = zope.configuration [test] [python] recipe = zc.recipe.egg eggs = zope.configuration interpreter = python zope2.13-2.13.21/source/zope.configuration/bootstrap.py0000644000175000017500000000742212214017543021655 0ustar arnauarnau############################################################################## # # Copyright (c) 2006 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

This makes it more likely other packages will generate deprecation warnings now, which will allow us to remove more outdated ones. - Don't fail when zope.testing is not installed. - Added missing ``processFile`` method to ``IConfigurationContext``. It is already implemented in the mix-in class, ``zope.configuration.config.ConfigurationContext``, and used by implementations of ``include`` and ``exclude`` directives. 3.5.0 (2009-02-26) ------------------ - Added the ``exclude`` directive to standard directives. It was previously available via ``zc.configuration`` package and now it's merged into ``zope.configuration``. - Changed package's mailing list address to zope-dev at zope.org, change "cheeseshop" to "pypi" in the package's url. 3.4.1 (2008-12-11) ------------------ - Use built-in 'set' type, rather than importin the 'sets' module, which is deprecated in Python 2.6. - Added support to bootstrap on Jython. 3.4.0 (2007-10-02) ------------------ - Initial release as a standalone package.

It is broken out in a separate file to provide an example of a grouping directive. The zope configuration directive is a pure grouping directive. It doesn't compute any actions on it's own. Instead, it allows a package to be specified, affecting the interpretation of relative dotted names and file paths. It also allows an i18n domain to be specified. The information collected is used by subdirectives. To define a grouping directive, we need to do three things: - Define a schema for the parameters passed to the directive - Define a handler class. - Register the class The parameter schema is given by IZopeConfigure. It specifies a package parameter and an i18n_domain parameter. The package parameter is specified as a ``GlobalObject``. This means it must be given as a dotted name that can be resolved through import. The i18n domain is just a plain (not unicode) string. The handler class has a constructor that takes a context to be adapted and zero or more arguments (depending on the paramter schema). The handler class must implement ``zope.configuration.interfaces.IGroupingContext``, which defines hooks ``before`` and ``after``, that are called with no arguments before and after nested directives are processed. If a grouping directive handler creates any actions, or does any computation, this is normally done in either the ``before`` or ``after`` hooks. Grouping handlers are normally decorators. The base class, ``zope.configuration.config.GroupingContextDecorator``, is normally used to define grouping directive handlers. It provides: - An implementation of IConfigurationContext, which grouping directive handlers should normally implement, - A default implementation of ``IGroupingContext`` that provides empty hooks. - Decorator support that uses a ``__getattr__`` method to delegate attribute accesses to adapted contexts, and - A constructor that sets the ``context`` attribute to the adapted context and assigns keyword arguments to attributes. The ``ZopeConfigure`` provides handling for the ``configure`` directive. It subclasses GroupingContextDecorator, and overrides the constructor to set the ``basepath`` attribute if a ``package`` argument is provided. Note that it delegates the job of assigning paramters to attribute to the ``GroupingContextDecorator`` constructor. The last step is to register the directive using the meta configuration directive. If we wanted to register the Zope ``configure`` directive for the ``zope`` namespace, we'd use a meta-configuration directive like:: Zope configure The ``configure`` node is normally used as the root node for a configuration file. It can also be used to specify a package or internationalization domain for a group of directives within a file by grouping those directives. We use the groupingDirective meta-directive to register a grouping directive. The parameters are self explanatory. The textual contents of the directive provide documentation text, excluding parameter documentation, which is provided by the schema. (The Zope ``configuration`` directive is actually registered using a lower-level Python API because it is registered for all namespaces, which isn't supported using the meta-configuration directives.)

It is based on the idea of configuration directives. Users of the configuration system provide configuration directives in some language that express configuration choices. The intent is that the language be pluggable. An XML language is provided by default. Configuration is performed in three stages. In the first stage, directives are processed to compute configuration actions. Configuration actions consist of: - A discriminator - A callable - Positional arguments - Keyword arguments The actions are essentially delayed function calls. Two or more actions conflict if they have the same discriminator. The configuration system has rules for resolving conflicts. If conflicts cannot be resolved, an error will result. Conflict resolution typically discards all but one of the conflicting actions, so that the remaining action of the originally-conflicting actions no longer conflicts. Non-conflicting actions are executed in the order that they were created by passing the positional and non-positional arguments to the action callable. The system is extensible. There is a meta-configuration language for defining configuration directives. A directive is defined by providing meta data about the directive and handler code to process the directive. There are four kinds of directives: - Simple directives compute configuration actions. Their handlers are typically functions that take a context and zero or more keyword arguments and return a sequence of configuration actions. To learn how to create simple directives, see `tests/test_simple.py`. - Grouping directives collect information to be used by nested directives. They are called with a context object which they adapt to some interface that extends IConfigurationContext. To learn how to create grouping directives, look at the documentation in zopeconfigure.py, which provides the implementation of the zope `configure` directive. Other directives can be nested in grouping directives. To learn how to implement nested directives, look at the documentation in `tests/test_nested.py`. - Complex directives are directives that have subdirectives. Subdirectives have handlers that are simply methods of complex directives. Complex diretives are handled by factories, typically classes, that create objects that have methods for handling subdirectives. These objects also have __call__ methods that are called when processing of subdirectives is finished. Complex directives only exist to support old directive handlers. They will probably be deprecated in the future. - Subdirectives are nested in complex directives. They are like simple directives except that they hane handlers that are complex directive methods. Subdirectives, like complex directives only exist to support old directive handlers. They will probably be deprecated in the future. zope2.13-2.13.21/source/zope.configuration/src/zope/configuration/fields.py0000644000175000017500000002750412214017543025524 0ustar arnauarnau############################################################################## # # Copyright (c) 2003 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

The value of the attribute is an expression which is used to determine if that element and its descendents are used. If the condition is true, processing continues normally, otherwise that element and its descendents are ignored. Currently the expression is always of the form "have featurename", and it checks for the presence of a . Our demonstration uses a trivial registry; each registration consists of a simple id inserted in the global `registry` in this module.

A simple directive is a directive that doesn't contain other directives. It can be implemented via a fairly simple function. To implement a simple directive, you need to do 3 things: - You need to create a schema to describe the directive parameters, - You need to write a directive handler, and - You need to register the directive. In this module, we'll implement a contrived example that records information about files in a file registry. The file registry is just the list, ``file_registry``. Our registry will contain tuples with: - file path - file title - description - Information about where the file was defined Our schema is defined in IRegisterFile (see below). Our schema lists the path and title. We'll get the description and other information for free, as we'll see later. The title is not required, and may be ommmitted. The job of a configuration handler is to compute one or more configuration actions. Configuration actions are defered function calls. The handler doesn't perform the actions. It just computes actions, which may be performed later if they are not overridden by other directives. Out handler is given in the function, ``registerFile``. It takes a context, a path and a title. All directive handlers take the directive context as the first argument. A directive context, at a minimim, implements, ``zope.configuration.IConfigurationContext``. (Specialized contexts can implement more specific interfaces. We'll say more about that when we talk about grouping directives.) The title argument must have a default value, because we indicated that the title was not required in the schema. (Alternatively, we could have made the title required, but provided a default value in the schema. In the first line of function `registerFile`, we get the context information object. This object contains information about the configuration directive, such as the file and location within the file of the directive. The context information object also has a text attribute that contains the textual data contained by the configuration directive. (This is the concatenation of all of the xml text nodes directly contained by the directive.) We use this for our description in the second line of the handler. The last thing the handler does is to compute an action by calling the action method of the context. It passes the action method 3 keyword arguments: - discriminator The discriminator is used to identify the action to be performed so that duplicate actions can be detected. Two actions are duplicated, and this conflict, if they have the same discriminator values and the values are not ``None``. Conflicting actions can be resolved if one of the conflicting actions is from a configuration file that directly or indirectly includes the files containing the other conflicting actions. In function ``registerFile``, we a tuple with the string ``'RegisterFile'`` and the path to be registered. - callable The callable is the object to be called to perform the action. - args The args argument contains positinal arguments to be passed to the callable. In function ``registerFile``, we pass a tuple containing a ``FileInfo`` object. (Note that there's nothing special about the FileInfo class. It has nothing to do with creating simple directives. It's just used in this example to organize the application data.) The final step in implementing the simple directive is to register it. We do that with the zcml ``meta:directive`` directive. This is given in the file simple.zcml. Here we specify the name, namespace, schema, and handler for the directive. We also provide a documentation for the directive as text between the start and end tags. The file simple.zcml also includes some directives that use the new directive to register some files. Now let's try it all out: >>> from zope.configuration import tests >>> context = xmlconfig.file("simple.zcml", tests) Now we should see some file information in the registry: >>> from zope.configuration.tests.test_xmlconfig import clean_text_w_paths >>> from zope.configuration.tests.test_xmlconfig import clean_path >>> for i in file_registry: ... print "path:", clean_path(i.path) ... print "title:", i.title ... print "description:", '\n'.join( ...

This is typically done either to: - Avoid repetative input. Information shared among multiple directives is provided in a surrounding directive. - Put together information that is too complex or structured to express with a single set of directive parameters. Grouping directives are used to handle both of these cases. See the documentation in ``../zopeconfigure.py``. This file describes the implementation of the zope ``configure`` directive, which groups directives that use a common package or internationalization domain. The documentation in ``../zopeconfigure.py`` provides background for the documentation here. You should also have read the documentation in ``test_simple.py``, which documents how to create simple directives. This file shows you how to handle the second case above. In this case, we have grouping directives that are meant to collaborate with specific contained directives. To do this, you have the grouping directives declare a more specific (or alternate) interface to ``IConfigurationContext``. Directives designed to work with those grouping directives are registered for the new interface. Let's look at example. Suppose we wanted to be able to define schema using ZCML. We'd use a grouping directive to specify schemas and contained directives to specify fields within the schema. We'll use a schema registry to hold the defined schemas. A schema has a name, an id, some documentation, and some fields. We'll provide the name and the id as parameters. We'll define fields as subdirectives and documentation as text contained in the schema directive. The schema directive uses the schema, ``ISchemaInfo`` for it's parameters. We also define the schema, ISchema, that specifies an attribute that nested field directives will use to store the fields they define. The class, ``Schema``, provides the handler for the schema directive. (If you haven't read the documentation in ``zopeconfigure.py``, you need to do so now.) The constructor saves its arguments as attributes and initializes its ``fields`` attribute. The ``after`` method of the ``Schema`` class creates a schema and computes an action to register the schema in the schema registry. The discriminator prevents two schema directives from registering the same schema. It's important to note that when we call the ``action`` method on ``self``, rather than on ``self.context``. This is because, in a grouping directive handler, the handler instance is itself a context. When we call the ``action`` method, the method stores additional meta data associated with the context it was called on. This meta data includes an include path, used when resolving conflicting actions, and an object that contains information about the XML source used to invole the directive. If we called the action method on ``self.context``, the wrong meta data would be associated with the configuration action. The file ``schema.zcml`` contains the meta-configuration directive that defines the schema directive. To define fields, we'll create directives to define the fields. Let's start with a ``text`` field. ``ITextField`` defines the schema for text field parameters. It extends ``IFieldInfo``, which defines data common to all fields. We also define a simple handler method, textField, that takes a context and keyword arguments. (For information on writing simple directives, see ``test_simple.py``.) We've abstracted most of the logic into the function ``field``. The ``field`` function computes a field instance using the constructor, and the keyword arguments passed to it. It also uses the context information object to get the text content of the directive, which it uses for the field description. After computing the field instance, it gets the ``Schema`` instance, which is the context of the context passed to the function. The function checks to see if there is already a field with that name. If there is, it raises an error. Otherwise, it saves the field. We also define an ``IIntInfo`` schema and ``intField`` handler function to support defining integer fields. We register the ``text`` and ``int`` directives in ``schema.zcml``. These are like the simple directive definition we saw in ``test_simple.py`` with an important exception. We provide a ``usedIn`` parameter to say that these directives can *only* ne used in a ``ISchema`` context. In other words, these can only be used inside of ``schema`` directives. The ``schema.zcml`` file also contains some sample ``schema`` directives. We can execute the file: >>> from zope.configuration import tests >>> context = xmlconfig.file("schema.zcml", tests) And verify that the schema registery has the schemas we expect: >>> from pprint import PrettyPrinter >>> pprint=PrettyPrinter(width=70).pprint >>> pprint(list(schema_registry)) ['zope.configuration.tests.test_nested.I1', 'zope.configuration.tests.test_nested.I2'] >>> def sorted(x): ... r = list(x) ... r.sort() ... return r >>> i1 = schema_registry['zope.configuration.tests.test_nested.I1'] >>> sorted(i1) ['a', 'b'] >>> i1['a'].__class__.__name__ 'Text' >>> i1['a'].description.strip() u'A\n\n Blah blah' >>> i1['a'].min_length 1 >>> i1['b'].__class__.__name__ 'Int' >>> i1['b'].description.strip() u'B\n\n Not feeling very creative' >>> i1['b'].min 1 >>> i1['b'].max 10 >>> i2 = schema_registry['zope.configuration.tests.test_nested.I2'] >>> sorted(i2) ['x', 'y'] Now let's look at some error situations. For example, let's see what happens if we use a field directive outside of a schema dorective. (Note that we used the context we created above, so we don't have to redefine our directives: >>> try: ... v = xmlconfig.string( ...

It is used to exclude processing of configuration files. It is useful when including a configuration that includes some other configuration that you don't want. It must be used BEFORE including the files to be excluded. First, let's look at an example. The zope.configuration.tests.excludedemo package has a ZCML configuration that includes some other configuration files. We'll set a log handler so we can see what's going on: >>> import logging, sys >>> logger = logging.getLogger('config') >>> oldlevel = logger.level >>> logger.setLevel(logging.DEBUG) >>> handler = logging.StreamHandler(sys.stdout) >>> logger.addHandler(handler) Now, we'll include the zope.configuration.tests.excludedemo config: >>> from zope.configuration import xmlconfig >>> _ = xmlconfig.string('') include /zope.configuration/src/zope/configuration/tests/excludedemo/configure.zcml include /zope.configuration/src/zope/configuration/tests/excludedemo/sub/configure.zcml include /zope.configuration/src/zope/configuration/tests/excludedemo/spam.zcml Each run of the configuration machinery runs with fresh state, so rerunning gives the same thing: >>> _ = xmlconfig.string('') include /zope.configuration/src/zope/configuration/tests/excludedemo/configure.zcml include /zope.configuration/src/zope/configuration/tests/excludedemo/sub/configure.zcml include /zope.configuration/src/zope/configuration/tests/excludedemo/spam.zcml Now, we'll use the exclude directive to exclude the two files included by the configuration file in zope.configuration.tests.excludedemo: >>> _ = xmlconfig.string( ... ''' ... ... ... ... ... ... ''') include /zope.configuration/src/zope/configuration/tests/excludedemo/configure.zcml .. cleanup >>> logger.setLevel(oldlevel) >>> logger.removeHandler(handler) zope2.13-2.13.21/source/zope.configuration/src/zope/configuration/xmlconfig.py0000644000175000017500000005471712214017543026252 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002, 2003 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

Detailed Documentation ---------------------- ========================== Zope configuration system ========================== The zope configuration system provides an extensible system for supporting variouse kinds of configurations. It is based on the idea of configuration directives. Users of the configuration system provide configuration directives in some language that express configuration choices. The intent is that the language be pluggable. An XML language is provided by default. Configuration is performed in three stages. In the first stage, directives are processed to compute configuration actions. Configuration actions consist of: - A discriminator - A callable - Positional arguments - Keyword arguments The actions are essentially delayed function calls. Two or more actions conflict if they have the same discriminator. The configuration system has rules for resolving conflicts. If conflicts cannot be resolved, an error will result. Conflict resolution typically discards all but one of the conflicting actions, so that the remaining action of the originally-conflicting actions no longer conflicts. Non-conflicting actions are executed in the order that they were created by passing the positional and non-positional arguments to the action callable. The system is extensible. There is a meta-configuration language for defining configuration directives. A directive is defined by providing meta data about the directive and handler code to process the directive. There are four kinds of directives: - Simple directives compute configuration actions. Their handlers are typically functions that take a context and zero or more keyword arguments and return a sequence of configuration actions. To learn how to create simple directives, see `tests/test_simple.py`. - Grouping directives collect information to be used by nested directives. They are called with a context object which they adapt to some interface that extends IConfigurationContext. To learn how to create grouping directives, look at the documentation in zopeconfigure.py, which provides the implementation of the zope `configure` directive. Other directives can be nested in grouping directives. To learn how to implement nested directives, look at the documentation in `tests/test_nested.py`. - Complex directives are directives that have subdirectives. Subdirectives have handlers that are simply methods of complex directives. Complex diretives are handled by factories, typically classes, that create objects that have methods for handling subdirectives. These objects also have __call__ methods that are called when processing of subdirectives is finished. Complex directives only exist to support old directive handlers. They will probably be deprecated in the future. - Subdirectives are nested in complex directives. They are like simple directives except that they hane handlers that are complex directive methods. Subdirectives, like complex directives only exist to support old directive handlers. They will probably be deprecated in the future. ======= Changes ======= 3.7.4 (2011-04-03) ------------------ - Test fixes for Windows. 3.7.3 (2011-03-11) ------------------ - Correctly locate packages with a __path__ attribute but no __file__ attribute (such as namespace packages installed with setup.py install --single-version-externally-managed). - Allow "info" and "includepath" to be passed optionally to context.action. 3.7.2 (2010-04-30) ------------------ - Prefer the standard libraries doctest module over zope.testing.doctest. 3.7.1 (2010-01-05) ------------------ - Jython support: use ``__builtin__`` module import rather than assuming ``__builtins__`` is available. - Jython support: deal with the fact that the Jython SAX parser returns attribute sets that have an empty string indicating no namespace instead of ``None``. - Allow ``setup.py test`` to run at least a subset of the tests that would be run when using the zope testrunner: ``setup.py test`` runs 53 tests, while ``bin/test`` runs 156. 3.7.0 (2009-12-22) ------------------ - Adjust testing output to newer zope.schema. - Prefer zope.testing.doctest over doctestunit. 3.6.0 (2009-04-01) ------------------ - Removed dependency of `zope.deprecation` package. - Don't suppress deprecation warnings any more in 'zope.configuration' package level. This makes it more likely other packages will generate deprecation warnings now, which will allow us to remove more outdated ones. - Don't fail when zope.testing is not installed. - Added missing ``processFile`` method to ``IConfigurationContext``. It is already implemented in the mix-in class, ``zope.configuration.config.ConfigurationContext``, and used by implementations of ``include`` and ``exclude`` directives. 3.5.0 (2009-02-26) ------------------ - Added the ``exclude`` directive to standard directives. It was previously available via ``zc.configuration`` package and now it's merged into ``zope.configuration``. - Changed package's mailing list address to zope-dev at zope.org, change "cheeseshop" to "pypi" in the package's url. 3.4.1 (2008-12-11) ------------------ - Use built-in 'set' type, rather than importin the 'sets' module, which is deprecated in Python 2.6. - Added support to bootstrap on Jython. 3.4.0 (2007-10-02) ------------------ - Initial release as a standalone package. Before 3.4.0 ------------ This package was part of the Zope 3 distribution and did not have its own CHANGES.txt. For earlier changes please refer to either our subversion log or the CHANGES.txt of earlier Zope 3 releases.

Unless you need ExtensionClasses for legacy applications (e.g. Zope 2), you probably want to use Python's new-style classes (available since Python 2.2). ComputedAttribute ----------------- This package provides a way to attach attributes to an ``ExtensionClass`` or instance that are computed by calling a callable. This works very much like ``property`` known from new-style classes, except that a ``ComputedAttribute`` can also be attached to an instance and that it honours ExtensionClass semantics (which is useful for retaining Acquisition wrappers, for example). MethodObject ------------ This package lets you attach additional "methods" to ExtensionClasses. These "methods" are actually implemented by subclassing the ``MethodObject.Method`` class and implementing the ``__call__`` method there. Instances of those classes will be bound to the instances they're attached to and will receive that instance object as a first parameter (after ``self``). zope2.13-2.13.21/source/ExtensionClass/setup.cfg0000644000175000017500000000007312214017441020216 0ustar arnauarnau[egg_info] tag_build = tag_date = 0 tag_svn_revision = 0 zope2.13-2.13.21/source/ExtensionClass/COPYRIGHT.txt0000644000175000017500000000004012214017441020500 0ustar arnauarnauZope Foundation and Contributorszope2.13-2.13.21/source/ExtensionClass/buildout.cfg0000644000175000017500000000025312214017441020705 0ustar arnauarnau[buildout] develop = . parts = test versions = versions [test] recipe = zc.recipe.testrunner eggs = ExtensionClass [versions] zc.buildout = 1.4.3 zc.recipe.egg = 1.2.2 zope2.13-2.13.21/source/ExtensionClass/bootstrap.py0000644000175000017500000000733612214017441020775 0ustar arnauarnau############################################################################## # # Copyright (c) 2006 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

Refs https://bugs.launchpad.net/zope2/+bug/143657. In order to take advantage of this optimization, you need to re-save your objects. 2.12.0 (2010-02-14) ------------------- - Removed old build artifacts and some metadata cleanup. - Added support for method cache in ExtensionClass. Patch contributed by Yoshinori K. Okuji. See https://bugs.launchpad.net/zope2/+bug/486182. 2.11.3 (2009-08-02) ------------------- - Further 64-bit fixes (Python 2.4 compatibility). 2.11.2 (2009-08-02) ------------------- - Fixed 64-bit compatibility issues for Python 2.5.x / 2.6.x. See http://www.python.org/dev/peps/pep-0353/ for details. 2.11.1 (2009-02-19) ------------------- - Initial egg release. zope2.13-2.13.21/source/ExtensionClass/src/0000755000175000017500000000000012214017441017164 5ustar arnauarnauzope2.13-2.13.21/source/ExtensionClass/src/ExtensionClass/0000755000175000017500000000000012214017441022126 5ustar arnauarnauzope2.13-2.13.21/source/ExtensionClass/src/ExtensionClass/pickle/0000755000175000017500000000000012214017441023375 5ustar arnauarnauzope2.13-2.13.21/source/ExtensionClass/src/ExtensionClass/pickle/pickle.c0000644000175000017500000002154512214017441025017 0ustar arnauarnau/* Copyright (c) 2003 Zope Foundation and Contributors.

As a meta-class, ExtensionClass provides the following features: - Support for a class initialiser: >>> from ExtensionClass import ExtensionClass, Base >>> class C(Base): ... def __class_init__(self): ... print 'class init called' ... print self.__name__ ... def bar(self): ... return 'bar called' class init called C >>> c = C() >>> int(c.__class__ is C) 1 >>> int(c.__class__ is type(c)) 1 - Making sure that every instance of the meta-class has Base as a base class: >>> class X: ... __metaclass__ = ExtensionClass >>> Base in X.__mro__ 1 - Provide an inheritedAttribute method for looking up attributes in base classes: >>> class C2(C): ... def bar(*a): ... return C2.inheritedAttribute('bar')(*a), 42 class init called C2 >>> o = C2() >>> o.bar() ('bar called', 42) This is for compatability with old code. New code should use super instead. The base class, Base, exists mainly to support the __of__ protocol. The __of__ protocol is similar to __get__ except that __of__ is called when an implementor is retrieved from an instance as well as from a class: >>> class O(Base): ... def __of__(*a): ... return a >>> o1 = O() >>> o2 = O() >>> C.o1 = o1 >>> c.o2 = o2 >>> c.o1 == (o1, c) 1 >>> C.o1 == o1 1 >>> int(c.o2 == (o2, c)) 1 We accomplish this by making a class that implements __of__ a descriptor and treating all descriptor ExtensionClasses this way. That is, if an extension class is a descriptor, it's __get__ method will be called even when it is retrieved from an instance. >>> class O(Base): ... def __get__(*a): ... return a ... >>> o1 = O() >>> o2 = O() >>> C.o1 = o1 >>> c.o2 = o2 >>> int(c.o1 == (o1, c, type(c))) 1 >>> int(C.o1 == (o1, None, type(c))) 1 >>> int(c.o2 == (o2, c, type(c))) 1 $Id: __init__.py 110581 2010-04-07 15:04:20Z tseaver $ """ from _ExtensionClass import * zope2.13-2.13.21/source/ExtensionClass/src/ExtensionClass/tests.py0000644000175000017500000004736612214017441023662 0ustar arnauarnau############################################################################## # # Copyright (c) 2003 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

Consider: >>> class X(Base): ... pass >>> class Y(Base): ... pass >>> class Z(Base): ... pass >>> class C(X, Y, Z): ... def foo(self): ... return 42 When we look up an attribute, we do the following: - Look in C's dictionary first. - Look up the attribute in X. We don't care how we get the attribute from X. If X is a new-style-class, we use the new algorithm. If X is a classic class, we use left-to-right depth-first. If X is an nsEC, use the "encapsulated base" algorithm. If we don't find the attribute in X, look in Y and then in Z, using the same approach. This algorithm will produce backward compatible results, providing the equivalent of left-to-right depth-first for nsECs and classic classes. We'll actually do something less abstract. We'll use a simple algorthm to merge the __mro__ of the base classes, computing an __mro__ for classic classes using the left-to-right depth-first algorithm. We'll basically lay the mros end-to-end left-to-right and remove repeats, keeping the first occurence of each class. >>> [c.__name__ for c in C.__mro__] ['C', 'X', 'Y', 'Z', 'Base', 'object'] For backward-compatability's sake, we actually depart from the above description a bit. We always put Base and object last in the mro, as shown in the example above. The primary reason for this is that object provides a do-nothing __init__ method. It is common practice to mix a C-implemented base class that implements a few methods with a Python class that implements those methods and others. The idea is that the C implementation overrides selected methods in C, so the C subclass is listed first. Unfortunately, because all extension classes are required to subclass Base, and thus, object, the C subclass brings along the __init__ object from objects, which would hide any __init__ method provided by the Python mix-in. Base and object are special in that they are implied by their meta classes. For example, a new-style class always has object as an ancestor, even if it isn't listed as a base: >>> class O: ... __metaclass__ = type >>> [c.__name__ for c in O.__bases__] ['object'] >>> [c.__name__ for c in O.__mro__] ['O', 'object'] Similarly, Base is always an ancestor of an extension class: >>> class E: ... __metaclass__ = ExtensionClass >>> [c.__name__ for c in E.__bases__] ['Base'] >>> [c.__name__ for c in E.__mro__] ['E', 'Base', 'object'] Base and object are generally added soley to get a particular meta class. They aren't used to provide application functionality and really shouldn't be considered when reasoning about where attributes come from. They do provide some useful default functionality and should be included at the end of the mro. Here are more examples: >>> from ExtensionClass import Base >>> class NA(object): ... pass >>> class NB(NA): ... pass >>> class NC(NA): ... pass >>> class ND(NB, NC): ... pass >>> [c.__name__ for c in ND.__mro__] ['ND', 'NB', 'NC', 'NA', 'object'] >>> class EA(Base): ... pass >>> class EB(EA): ... pass >>> class EC(EA): ... pass >>> class ED(EB, EC): ... pass >>> [c.__name__ for c in ED.__mro__] ['ED', 'EB', 'EA', 'EC', 'Base', 'object'] >>> class EE(ED, ND): ... pass >>> [c.__name__ for c in EE.__mro__] ['EE', 'ED', 'EB', 'EA', 'EC', 'ND', 'NB', 'NC', 'NA', 'Base', 'object'] >>> class EF(ND, ED): ... pass >>> [c.__name__ for c in EF.__mro__] ['EF', 'ND', 'NB', 'NC', 'NA', 'ED', 'EB', 'EA', 'EC', 'Base', 'object'] >>> class CA: ... pass >>> class CB(CA): ... pass >>> class CC(CA): ... pass >>> class CD(CB, CC): ... pass >>> class ECD(Base, CD): ... pass >>> [c.__name__ for c in ECD.__mro__] ['ECD', 'CD', 'CB', 'CA', 'CC', 'Base', 'object'] >>> class CDE(CD, Base): ... pass >>> [c.__name__ for c in CDE.__mro__] ['CDE', 'CD', 'CB', 'CA', 'CC', 'Base', 'object'] >>> class CEND(CD, ED, ND): ... pass >>> [c.__name__ for c in CEND.__mro__] ['CEND', 'CD', 'CB', 'CA', 'CC', """ \ """'ED', 'EB', 'EA', 'EC', 'ND', 'NB', 'NC', 'NA', 'Base', 'object'] """ def test_avoiding___init__decoy_w_inheritedAttribute(): """ >>> class Decoy(Base): ... pass >>> class B(Base): ... def __init__(self, a, b): ... print '__init__', a, b >>> class C(Decoy, B): ... def __init__(self): ... print 'C init' ...

This extra member is a method chain ('PyMethodChain') containing a linked list of method definition ('PyMethodDef') lists. Method chains can be used to implement method inheritance in C. Most extensions don't use method chains, but simply define method lists, which are null-terminated arrays of method definitions. A macro, 'METHOD_CHAIN' is defined in 'ExtensionClass.h' that converts a method list to a method chain. (See the example below.) - Module functions that create new instances must be replaced by an '__init__' method that initializes, but does not create storage for instances. - The extension class must be initialized and exported to the module with:: PyExtensionClass_Export(d,"name",type); where 'name' is the module name and 'type' is the extension class type object. Attribute lookup Attribute lookup is performed by calling the base extension class 'getattr' operation for the base extension class that includes C data, or for the first base extension class, if none of the base extension classes include C data. 'ExtensionClass.h' defines a macro 'Py_FindAttrString' that can be used to find an object's attributes that are stored in the object's instance dictionary or in the object's class or base classes:: v = Py_FindAttrString(self,name); In addition, a macro is provided that replaces 'Py_FindMethod' calls with logic to perform the same sort of lookup that is provided by 'Py_FindAttrString'. Linking The extension class mechanism was designed to be useful with dynamically linked extension modules. Modules that implement extension classes do not have to be linked against an extension class library. The macro 'PyExtensionClass_Export' imports the 'ExtensionClass' module and uses objects imported from this module to initialize an extension class with necessary behavior. */ #ifndef EXTENSIONCLASS_H #define EXTENSIONCLASS_H #include "Python.h" #include "import.h" /* Declarations for objects of type ExtensionClass */ #define EC PyTypeObject #define PyExtensionClass PyTypeObject #define EXTENSIONCLASS_BINDABLE_FLAG 1 << 2 #define EXTENSIONCLASS_NOINSTDICT_FLAG 1 << 5 typedef struct { PyObject_HEAD } _emptyobject; static struct ExtensionClassCAPIstruct { /***************************************************************************** WARNING: THIS STRUCT IS PRIVATE TO THE EXTENSION CLASS INTERFACE IMPLEMENTATION AND IS SUBJECT TO CHANGE !!! *****************************************************************************/ PyObject *(*EC_findiattrs_)(PyObject *self, char *cname); int (*PyExtensionClass_Export_)(PyObject *dict, char *name, PyTypeObject *typ); PyObject *(*PyECMethod_New_)(PyObject *callable, PyObject *inst); PyExtensionClass *ECBaseType_; PyExtensionClass *ECExtensionClassType_; } *PyExtensionClassCAPI = NULL; #define ECBaseType (PyExtensionClassCAPI->ECBaseType_) #define ECExtensionClassType (PyExtensionClassCAPI->ECExtensionClassType_) /* Following are macros that are needed or useful for defining extension classes: */ /* This macro redefines Py_FindMethod to do attribute for an attribute name given by a C string lookup using extension class meta-data.

Unless you need ExtensionClasses for legacy applications (e.g. Zope 2), you probably want to use Python's new-style classes (available since Python 2.2). ComputedAttribute ----------------- This package provides a way to attach attributes to an ``ExtensionClass`` or instance that are computed by calling a callable. This works very much like ``property`` known from new-style classes, except that a ``ComputedAttribute`` can also be attached to an instance and that it honours ExtensionClass semantics (which is useful for retaining Acquisition wrappers, for example). MethodObject ------------ This package lets you attach additional "methods" to ExtensionClasses. These "methods" are actually implemented by subclassing the ``MethodObject.Method`` class and implementing the ``__call__`` method there. Instances of those classes will be bound to the instances they're attached to and will receive that instance object as a first parameter (after ``self``). Changelog ========= 2.13.2 (2010-06-16) ------------------- - LP #587760: Handle tp_basicsize correctly. 2.13.1 (2010-04-03) ------------------- - Removed undeclared testing dependency on zope.testing. - Removed cruft in ``pickle/pickle.c`` related to removed ``__getnewargs__``. 2.13.0 (2010-02-22) ------------------- - Avoid defining ``__getnewargs__`` as not to defeat the ZODB persistent reference optimization. Refs https://bugs.launchpad.net/zope2/+bug/143657. In order to take advantage of this optimization, you need to re-save your objects. 2.12.0 (2010-02-14) ------------------- - Removed old build artifacts and some metadata cleanup. - Added support for method cache in ExtensionClass. Patch contributed by Yoshinori K. Okuji. See https://bugs.launchpad.net/zope2/+bug/486182. 2.11.3 (2009-08-02) ------------------- - Further 64-bit fixes (Python 2.4 compatibility). 2.11.2 (2009-08-02) ------------------- - Fixed 64-bit compatibility issues for Python 2.5.x / 2.6.x. See http://www.python.org/dev/peps/pep-0353/ for details. 2.11.1 (2009-02-19) ------------------- - Initial egg release.

The encoding for a value x is represented as a unary part and a binary part. The unary part is a sequence of 1 bits followed by a 0 bit. The binary part encodes some of the lower bits of x-1. The encoding is parameterized by a value m that describes how many bits to store in the binary part. If most of the values are smaller than 2**m then they can be stored in only m+1 bits.

This is intended for lists of word ids (wids). The # ordinary string .find() method can be used to find the encoded form of a # desired wid-string in an encoded wid-string. As in UTF-8, the initial byte # of an encoding can't appear in the interior of an encoding, so find() can't # be fooled into starting a match "in the middle" of an encoding. Unlike # UTF-8, the initial byte does not tell you how many continuation bytes # follow; and there's no ASCII superset property. # Details: # # + Only the first byte of an encoding has the sign bit set. # # + The first byte has 7 bits of data. # # + Bytes beyond the first in an encoding have the sign bit clear, followed # by 7 bits of data. # # + The first byte doesn't tell you how many continuation bytes are # following.

ZCTextIndex Lexicons store the words indexed by ZCTextIndexes in a ZCatalog. Controls 'Id' -- Allows you to specify the id of the ZCTextIndex Lexicon. 'Title' -- Allows you to specify the title of the ZCTextIndex Lexicon. Pipeline Stages The remaining controls allow you to select the desired processing of text to index by selecting pipeline stages. The default available stages are: - **Word Splitter** This is the only mandatory stage. The word splitter breaks the text up into a list of words. Included is a simple whitespace splitter, and a splitter that removes HTML tags. The HTML aware splitter gives best results when all of the incoming content to index is HTML. - **Stop Words** To conserve space in the vocabulary, and possibly increase performance, you can select a stop word remover which subtracts very common or single letter words from the Lexicon. Bear in mind that you will not be able to search on removed stop words, and they will also be removed from queries passed to search ZCTextIndexes using the Lexicon. - **Case Normalizer** The case normalizer removes case information from the words in the Lexicon. If case-sensitive searching is desires, then omit this element from the pipeline. zope2.13-2.13.21/source/Products.ZCTextIndex/src/Products/ZCTextIndex/help/ZCTextIndex_Add.stx0000644000175000017500000000317512214017454030574 0ustar arnauarnauZCTextIndex Add: Create a new ZCTextIndex Description A ZCTextIndex is an index for performing full text searches over bodies of text. It includes the following features: - Boolean query operators with parenthetical grouping - Globbing (partial word) and phrase matching - Two selectable relevance scoring algorithms ZCTextIndex is designed as a replacement for standard TextIndex, and has several advantages over it. Controls 'Id' -- The id of the ZCTextIndex, must be unique for this ZCatalog. 'Field Name' -- The name of the field (object attribute) to be indexed. 'Ranking Strategy' - **Okapi BM25 Rank** A relevance scoring technique that seems to work well when the document text is considerably longer than the query string, which is often the case with user specified query strings. - **Cosine Measure** A relevance scoring technique derived from the "*Managing Gigabytes*":http://www.cs.mu.oz.au/mg/ book. It seems to work best when the queries are similar in size and content to the text they are searching. 'Lexicon' -- The ZCTextIndex Lexicon to be used by this ZCTextIndex. Lexicons process and store the words from the text and help in processing queries. You must define a ZCTextIndex Lexicon before you can create a ZCTextIndex. Several ZCTextIndexes can share the same Lexicon if desired. zope2.13-2.13.21/source/Products.ZCTextIndex/src/Products/ZCTextIndex/README.txt0000644000175000017500000000717512214017454025665 0ustar arnauarnauZCTextIndex =========== This product is a replacement for the full text indexing facility of ZCatalog. Specifically, it is an alternative to PluginIndexes/TextIndex. Advantages of using ZCTextIndex over TextIndex: - A new query language, supporting both explicit and implicit Boolean operators, parentheses, globbing, and phrase searching. Apart from explicit operators and globbing, the syntax is roughly the same as that popularized by Google. - A more refined scoring algorithm, resulting in better selectiveness: it's much more likely that you'll find the document you are looking for among the first few highest-ranked results. - Actually, ZCTextIndex gives you a choice of two scoring algorithms from recent literature: the Cosine ranking from the Managing Gigabytes book, and Okapi from more recent research papers. Okapi usually does better, so it is the default (but your milage may vary). - A redesigned Lexicon, using a pipeline architecture to split the input text into words. This makes it possible to mix and match pipeline components, e.g. you can choose between an HTML-aware splitter and a plain text splitter, and additional components can be added to the pipeline for case folding, stopword removal, and other features. Enough example pipeline components are provided to get you started, and it is very easy to write new components. Performance is roughly the same as for TextIndex, and we're expecting to make tweaks to the code that will make it faster. This code can be used outside of Zope too; all you need is a standalone ZODB installation to make your index persistent. Several functional test programs in the tests subdirectory show how to do this, for example mhindex.py, mailtest.py, indexhtml.py, and queryhtml.py. See the online help for how to use ZCTextIndex within Zope. (Included in the subdirectory "help".)

It's based on probability arguments about how words are distributed in documents, not on an abstract vector space model. A long paper by its principal inventors gives an excellent overview of how it was derived: A probabilistic model of information retrieval: development and status K. Sparck Jones, S. Walker, S.E. Robertson http://citeseer.nj.nec.com/jones98probabilistic.html Spellings that ignore relevance information (which we don't have) are of this high-level form: score(D, Q) = sum(for t in D&Q: TF(D, t) * IDF(Q, t)) where D a specific document Q a specific query t a term (word, atomic phrase, whatever) D&Q the terms common to D and Q TF(D, t) a measure of t's importance in D -- a kind of term frequency weight IDF(Q, t) a measure of t's importance in the query and in the set of documents as a whole -- a kind of inverse document frequency weight The IDF(Q, t) here is identical to the one used for our cosine measure. Since queries are expected to be short, it ignores Q entirely: IDF(Q, t) = log(1.0 + N / f(t)) where N the total number of documents f(t) the number of documents in which t appears Most Okapi literature seems to use log(N/f(t)) instead. We don't, because that becomes 0 for a term that's in every document, and, e.g., if someone is searching for "documentation" on python.org (a term that may well show up on every page, due to the top navigation bar), we still want to find the pages that use the word a lot (which is TF's job to find, not IDF's -- we just want to stop IDF from considering this t to be irrelevant). The TF(D, t) spellings are more interesting. With lots of variations, the most basic spelling is of the form f(D, t) TF(D, t) = --------------- f(D, t) + K(D) where f(D, t) the number of times t appears in D K(D) a measure of the length of D, normalized to mean doc length The functional *form* f/(f+K) is clever. It's a gross approximation to a mixture of two distinct Poisson distributions, based on the idea that t probably appears in D for one of two reasons: 1. More or less at random. 2. Because it's important to D's purpose in life ("eliteness" in papers). Note that f/(f+K) is always between 0 and 1. If f is very large compared to K, it approaches 1. If K is very large compared to f, it approaches 0. If t appears in D more or less "for random reasons", f is likely to be small, and so K will dominate unless it's a very small doc, and the ratio will be small. OTOH, if t appears a lot in D, f will dominate unless it's a very large doc, and the ratio will be close to 1. We use a variation on that simple theme, a simplification of what's called BM25 in the literature (it was the 25th stab at a Best Match function from the Okapi group; "a simplification" means we're setting some of BM25's more esoteric free parameters to 0): f(D, t) * (k1 + 1) TF(D, t) = -------------------- f(D, t) + k1 * K(D) where k1 a "tuning factor", typically between 1.0 and 2.0. We use 1.2, the usual default value. This constant adjusts the curve to look more like a theoretical 2-Poisson curve. Note that as f(D, t) increases, TF(D, t) increases monotonically, approaching an asymptote of k1+1 from below. Finally, we use K(D) = (1-b) + b * len(D)/E(len(D)) where b is another free parameter, discussed below. We use 0.75. len(D) the length of D in words E(len(D)) the expected value of len(D) across the whole document set; or, IOW, the average document length b is a free parameter between 0.0 and 1.0, and adjusts for the expected effect of the "Verbosity Hypothesis". Suppose b is 1, and some word t appears 10 times as often in document d2 than in document d1. If document d2 is also 10 times as long as d1, TF(d1, t) and TF(d2, t) are identical: f(d2, t) * (k1 + 1) TF(d2, t) = --------------------------------- = f(d2, t) + k1 * len(d2)/E(len(D)) 10 * f(d1, t) * (k1 + 1) ----------------------------------------------- = TF(d1, t) 10 * f(d1, t) + k1 * (10 * len(d1))/E(len(D)) because the 10's cancel out. This is appropriate if we believe that a word appearing 10x more often in a doc 10x as long is simply due to that the longer doc is more verbose. If we do believe that, the longer doc and the shorter doc are probably equally relevant. OTOH, it *could* be that the longer doc is talking about t in greater depth too, in which case it's probably more relevant than the shorter doc. At the other extreme, if we set b to 0, the len(D)/E(len(D)) term vanishes completely, and a doc scores higher for having more occurences of a word regardless of the doc's length. Reality is between these extremes, and probably varies by document and word too. Reports in the literature suggest that b=0.75 is a good compromise "in general", favoring the "verbosity hypothesis" end of the scale. Putting it all together, the final TF function is f(D, t) * (k1 + 1) TF(D, t) = -------------------------------------------- f(D, t) + k1 * ((1-b) + b*len(D)/E(len(D))) with k1=1.2 and b=0.75. Query Term Weighting -------------------- I'm ignoring the query adjustment part of Okapi BM25 because I expect our queries are very short. Full BM25 takes them into account by adding the following to every score(D, Q); it depends on the lengths of D and Q, but not on the specific words in Q, or even on whether they appear in D(!): E(len(D)) - len(D) k2 * len(Q) * ------------------- E(len(D)) + len(D) Here k2 is another "tuning constant", len(Q) is the number of words in Q, and len(D) & E(len(D)) were defined above. The Okapi group set k2 to 0 in TREC-9, so it apparently doesn't do much good (or may even hurt). Full BM25 *also* multiplies the following factor into IDF(Q, t): f(Q, t) * (k3 + 1) ------------------ f(Q, t) + k3 where k3 is yet another free parameter, and f(Q,t) is the number of times t appears in Q. Since we're using short "web style" queries, I expect f(Q,t) to always be 1, and then that quotient is 1 * (k3 + 1) ------------ = 1 1 + k3 regardless of k3's value. So, in a trivial sense, we are incorporating this measure (and optimizing it by not bothering to multiply by 1 ).

usage: python mailtest.py [options] options: -v -- verbose Index Generation -i mailbox -n NNN -- max number of messages to read from mailbox -t NNN -- commit a transaction every NNN messages (default: 1) -p NNN -- pack every NNN messages (default: 500), and at end -p 0 -- don't pack at all -x -- exclude the message text from the data.fs Queries -q query -b NNN -- return the NNN best matches (default: 10) -c NNN -- context; if -v, show the first NNN lines of results (default: 5) The script either indexes or queries depending on whether -q or -i is passed as an option. For -i mailbox, the script reads mail messages from the mailbox and indexes them. It indexes one message at a time, then commits the transaction. For -q query, it performs a query on an existing index. If both are specified, the index is performed first. You can also interact with the index after it is completed.

This particular parser recognizes the following syntax: Start = OrExpr OrExpr = AndExpr ('OR' AndExpr)* AndExpr = Term ('AND' NotExpr)* NotExpr = ['NOT'] Term Term = '(' OrExpr ')' | ATOM+ The key words (AND, OR, NOT) are recognized in any mixture of case. An ATOM is either: + A sequence of characters not containing whitespace or parentheses or double quotes, and not equal (ignoring case) to one of the key words 'AND', 'OR', 'NOT'; or + A non-empty string enclosed in double quotes. The interior of the string can contain whitespace, parentheses and key words, but not quotes. + A hyphen followed by one of the two forms above, meaning that it must not be present. An unquoted ATOM may also contain globbing characters. Globbing syntax is defined by the lexicon; for example "foo*" could mean any word starting with "foo". When multiple consecutive ATOMs are found at the leaf level, they are connected by an implied AND operator, and an unquoted leading hyphen is interpreted as a NOT operator. Summarizing the default operator rules: - a sequence of words without operators implies AND, e.g. ``foo bar'' - double-quoted text implies phrase search, e.g. ``"foo bar"'' - words connected by punctuation implies phrase search, e.g. ``foo-bar'' - a leading hyphen implies NOT, e.g. ``foo -bar'' - these can be combined, e.g. ``foo -"foo bar"'' or ``foo -foo-bar'' - * and ?

It is maintained by the* `Zope Toolkit project `_. This package represents the core of the Zope Component Architecture. Together with the 'zope.interface' package, it provides facilities for defining, registering and looking up components. .. contents:: Detailed Documentation ********************** Zope Component Architecture =========================== This package, together with `zope.interface`, provides facilities for defining, registering and looking up components. There are two basic kinds of components: adapters and utilities. Utilities --------- Utilities are just components that provide an interface and that are looked up by an interface and a name. Let's look at a trivial utility definition: >>> from zope import interface >>> class IGreeter(interface.Interface): ... def greet(): ... "say hello" >>> class Greeter: ... interface.implements(IGreeter) ... ... def __init__(self, other="world"): ... self.other = other ... ... def greet(self): ... print "Hello", self.other We can register an instance this class using `provideUtility` [1]_: >>> from zope import component >>> greet = Greeter('bob') >>> component.provideUtility(greet, IGreeter, 'robert') In this example we registered the utility as providing the `IGreeter` interface with a name of 'bob'. We can look the interface up with either `queryUtility` or `getUtility`: >>> component.queryUtility(IGreeter, 'robert').greet() Hello bob >>> component.getUtility(IGreeter, 'robert').greet() Hello bob `queryUtility` and `getUtility` differ in how failed lookups are handled: >>> component.queryUtility(IGreeter, 'ted') >>> component.queryUtility(IGreeter, 'ted', 42) 42 >>> component.getUtility(IGreeter, 'ted') ... # doctest: +ELLIPSIS Traceback (most recent call last): ... ComponentLookupError: (, 'ted') If a component provides only one interface, as in the example above, then we can omit the provided interface from the call to `provideUtility`: >>> ted = Greeter('ted') >>> component.provideUtility(ted, name='ted') >>> component.queryUtility(IGreeter, 'ted').greet() Hello ted The name defaults to an empty string: >>> world = Greeter() >>> component.provideUtility(world) >>> component.queryUtility(IGreeter).greet() Hello world Adapters -------- Adapters are components that are computed from other components to adapt them to some interface. Because they are computed from other objects, they are provided as factories, usually classes. Here, we'll create a greeter for persons, so we can provide personalized greetings for different people: >>> class IPerson(interface.Interface): ... name = interface.Attribute("Name") >>> class PersonGreeter: ... ... component.adapts(IPerson) ... interface.implements(IGreeter) ... ... def __init__(self, person): ... self.person = person ... ... def greet(self): ... print "Hello", self.person.name The class defines a constructor that takes an argument for every object adapted. We used `component.adapts` to declare what we adapt. We can find out if an object declares that it adapts anything using adaptedBy: >>> list(component.adaptedBy(PersonGreeter)) == [IPerson] True If an object makes no declaration, then None is returned: >>> component.adaptedBy(Greeter()) is None True If we declare the interfaces adapted and if we provide only one interface, as in the example above, then we can provide the adapter very simply [1]_: >>> component.provideAdapter(PersonGreeter) For adapters that adapt a single interface to a single interface without a name, we can get the adapter by simply calling the interface: >>> class Person: ... interface.implements(IPerson) ... ... def __init__(self, name): ... self.name = name >>> IGreeter(Person("Sally")).greet() Hello Sally We can also provide arguments to be very specific about what how to register the adapter. >>> class BobPersonGreeter(PersonGreeter): ... name = 'Bob' ... def greet(self): ... print "Hello", self.person.name, "my name is", self.name >>> component.provideAdapter( ... BobPersonGreeter, [IPerson], IGreeter, 'bob') The arguments can also be provided as keyword arguments: >>> class TedPersonGreeter(BobPersonGreeter): ... name = "Ted" >>> component.provideAdapter( ... factory=TedPersonGreeter, adapts=[IPerson], ... provides=IGreeter, name='ted') For named adapters, use `queryAdapter`, or `getAdapter`: >>> component.queryAdapter(Person("Sally"), IGreeter, 'bob').greet() Hello Sally my name is Bob >>> component.getAdapter(Person("Sally"), IGreeter, 'ted').greet() Hello Sally my name is Ted If an adapter can't be found, `queryAdapter` returns a default value and `getAdapter` raises an error: >>> component.queryAdapter(Person("Sally"), IGreeter, 'frank') >>> component.queryAdapter(Person("Sally"), IGreeter, 'frank', 42) 42 >>> component.getAdapter(Person("Sally"), IGreeter, 'frank') ... # doctest: +ELLIPSIS Traceback (most recent call last): ... ComponentLookupError: (...Person...>, <...IGreeter>, 'frank') Adapters can adapt multiple objects: >>> class TwoPersonGreeter: ... ... component.adapts(IPerson, IPerson) ... interface.implements(IGreeter) ... ... def __init__(self, person, greeter): ... self.person = person ... self.greeter = greeter ... ... def greet(self): ... print "Hello", self.person.name ... print "my name is", self.greeter.name >>> component.provideAdapter(TwoPersonGreeter) To look up a multi-adapter, use either `queryMultiAdapter` or `getMultiAdapter`: >>> component.queryMultiAdapter((Person("Sally"), Person("Bob")), ... IGreeter).greet() Hello Sally my name is Bob Adapters need not be classes. Any callable will do. We use the adapter decorator (in the Python 2.4 decorator sense) to declare that a callable object adapts some interfaces (or classes): >>> class IJob(interface.Interface): ... "A job" >>> class Job: ... interface.implements(IJob) >>> def personJob(person): ... return getattr(person, 'job', None) >>> personJob = interface.implementer(IJob)(personJob) >>> personJob = component.adapter(IPerson)(personJob) In Python 2.4, the example can be written: >>> @interface.implementer(IJob) ... @component.adapter(IPerson) ... def personJob(person): ... return getattr(person, 'job', None) which looks a bit nicer. In this example, the personJob function simply returns the person's `job` attribute if present, or None if it's not present. An adapter factory can return None to indicate that adaptation wasn't possible. Let's register this adapter and try it out: >>> component.provideAdapter(personJob) >>> sally = Person("Sally") >>> IJob(sally) # doctest: +ELLIPSIS Traceback (most recent call last): ... TypeError: ('Could not adapt', ... The adaptation failed because sally didn't have a job. Let's give her one: >>> job = Job() >>> sally.job = job >>> IJob(sally) is job True Subscription Adapters --------------------- Unlike regular adapters, subscription adapters are used when we want all of the adapters that adapt an object to a particular adapter. Consider a validation problem. We have objects and we want to assess whether they meet some sort of standards. We define a validation interface: >>> class IValidate(interface.Interface): ... def validate(ob): ... """Determine whether the object is valid ... ... Return a string describing a validation problem. ... An empty string is returned to indicate that the ... object is valid. ... """ Perhaps we have documents: >>> class IDocument(interface.Interface): ... summary = interface.Attribute("Document summary") ... body = interface.Attribute("Document text") >>> class Document: ... interface.implements(IDocument) ... def __init__(self, summary, body): ... self.summary, self.body = summary, body Now, we may want to specify various validation rules for documents. For example, we might require that the summary be a single line: >>> class SingleLineSummary: ... component.adapts(IDocument) ... interface.implements(IValidate) ... ... def __init__(self, doc): ... self.doc = doc ... ... def validate(self): ... if '\n' in self.doc.summary: ... return 'Summary should only have one line' ... else: ... return '' Or we might require the body to be at least 1000 characters in length: >>> class AdequateLength: ... component.adapts(IDocument) ... interface.implements(IValidate) ... ... def __init__(self, doc): ... self.doc = doc ... ... def validate(self): ... if len(self.doc.body) < 1000: ... return 'too short' ... else: ... return '' We can register these as subscription adapters [1]_: >>> component.provideSubscriptionAdapter(SingleLineSummary) >>> component.provideSubscriptionAdapter(AdequateLength) We can then use the subscribers to validate objects: >>> doc = Document("A\nDocument", "blah") >>> [adapter.validate() ... for adapter in component.subscribers([doc], IValidate) ... if adapter.validate()] ['Summary should only have one line', 'too short'] >>> doc = Document("A\nDocument", "blah" * 1000) >>> [adapter.validate() ... for adapter in component.subscribers([doc], IValidate) ... if adapter.validate()] ['Summary should only have one line'] >>> doc = Document("A Document", "blah") >>> [adapter.validate() ... for adapter in component.subscribers([doc], IValidate) ... if adapter.validate()] ['too short'] Handlers -------- Handlers are subscription adapter factories that don't produce anything. They do all of their work when called. Handlers are typically used to handle events. Event subscribers are different from other subscription adapters in that the caller of event subscribers doesn't expect to interact with them in any direct way. For example, an event publisher doesn't expect to get any return value. Because subscribers don't need to provide an API to their callers, it is more natural to define them with functions, rather than classes. For example, in a document-management system, we might want to record creation times for documents: >>> import datetime >>> def documentCreated(event): ... event.doc.created = datetime.datetime.utcnow() In this example, we have a function that takes an event and performs some processing. It doesn't actually return anything. This is a special case of a subscription adapter that adapts an event to nothing. All of the work is done when the adapter "factory" is called. We call subscribers that don't actually create anything "handlers". There are special APIs for registering and calling them. To register the subscriber above, we define a document-created event: >>> class IDocumentCreated(interface.Interface): ... doc = interface.Attribute("The document that was created") >>> class DocumentCreated: ... interface.implements(IDocumentCreated) ... ... def __init__(self, doc): ... self.doc = doc We'll also change our handler definition to: >>> def documentCreated(event): ... event.doc.created = datetime.datetime.utcnow() >>> documentCreated = component.adapter(IDocumentCreated)(documentCreated) Note that in Python 2.4, this can be written: >>> @component.adapter(IDocumentCreated) ... def documentCreated(event): ... event.doc.created = datetime.datetime.utcnow() This marks the handler as an adapter of `IDocumentCreated` events. Now we'll register the handler [1]_: >>> component.provideHandler(documentCreated) Now, if we can create an event and use the `handle` function to call handlers registered for the event: >>> component.handle(DocumentCreated(doc)) >>> doc.created.__class__.__name__ 'datetime' .. [1] CAUTION: This API should only be used from test or application-setup code. This API shouldn't be used by regular library modules, as component registration is a configuration activity. Events ====== The Component Architecture provides a way to dispatch events to event handlers. Event handlers are registered as *subscribers* a.k.a. *handlers*. Before we can start we need to import ``zope.component.event`` to make the dispatching effective: >>> import zope.component.event Consider two event classes: >>> class Event1(object): ... pass >>> class Event2(Event1): ... pass Now consider two handlers for these event classes: >>> called = [] >>> import zope.component >>> @zope.component.adapter(Event1) ... def handler1(event): ... called.append(1) >>> @zope.component.adapter(Event2) ... def handler2(event): ... called.append(2) We can register them with the Component Architecture: >>> zope.component.provideHandler(handler1) >>> zope.component.provideHandler(handler2) Now let's go through the events. We'll see that the handlers have been called accordingly: >>> from zope.event import notify >>> notify(Event1()) >>> called [1] >>> del called[:] >>> notify(Event2()) >>> called.sort() >>> called [1, 2] Object events ------------- The ``objectEventNotify`` function is a subscriber to dispatch ObjectEvents to interested adapters. First create an object class: >>> class IUseless(zope.interface.Interface): ... """Useless object""" >>> class UselessObject(object): ... """Useless object""" ... zope.interface.implements(IUseless) Then create an event class: >>> class IObjectThrownEvent(zope.component.interfaces.IObjectEvent): ... """An object has been thrown away""" >>> class ObjectThrownEvent(zope.component.interfaces.ObjectEvent): ... """An object has been thrown away""" ... zope.interface.implements(IObjectThrownEvent) Create an object and an event: >>> hammer = UselessObject() >>> event = ObjectThrownEvent(hammer) Then notify the event to the subscribers. Since the subscribers list is empty, nothing happens. >>> zope.component.event.objectEventNotify(event) Now create an handler for the event: >>> events = [] >>> def record(*args): ... events.append(args) >>> zope.component.provideHandler(record, [IUseless, IObjectThrownEvent]) The event is notified to the subscriber: >>> zope.component.event.objectEventNotify(event) >>> events == [(hammer, event)] True Following test demonstrates how a subscriber can raise an exception to prevent an action. >>> zope.component.provideHandler(zope.component.event.objectEventNotify) Let's create a container: >>> class ToolBox(dict): ... def __delitem__(self, key): ... notify(ObjectThrownEvent(self[key])) ... return super(ToolBox,self).__delitem__(key) >>> container = ToolBox() And put the object into the container: >>> container['Red Hammer'] = hammer Create an handler function that will raise an error when called: >>> class Veto(Exception): ... pass >>> def callback(item, event): ... assert(item == event.object) ... raise Veto Register the handler: >>> zope.component.provideHandler(callback, [IUseless, IObjectThrownEvent]) Then if we try to remove the object, an ObjectThrownEvent is fired: >>> del container['Red Hammer'] ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... raise Veto Veto Factories ========= The Factory Class ----------------- >>> from zope.interface import Interface >>> class IFunction(Interface): ... pass >>> class IKlass(Interface): ... pass >>> from zope.interface import implements >>> class Klass(object): ... implements(IKlass) ... ... def __init__(self, *args, **kw): ... self.args = args ... self.kw = kw >>> from zope.component.factory import Factory >>> factory = Factory(Klass, 'Klass', 'Klassier') >>> factory2 = Factory(lambda x: x, 'Func', 'Function') >>> factory3 = Factory(lambda x: x, 'Func', 'Function', (IFunction,)) Calling a Factory ~~~~~~~~~~~~~~~~~ Here we test whether the factory correctly creates the objects and including the correct handling of constructor elements. First we create a factory that creates instanace of the `Klass` class: >>> factory = Factory(Klass, 'Klass', 'Klassier') Now we use the factory to create the instance >>> kl = factory(1, 2, foo=3, bar=4) and make sure that the correct class was used to create the object: >>> kl.__class__ Since we passed in a couple positional and keyword arguments >>> kl.args (1, 2) >>> kl.kw {'foo': 3, 'bar': 4} >>> factory2(3) 3 >>> factory3(3) 3 Title and Description ~~~~~~~~~~~~~~~~~~~~~ >>> factory.title 'Klass' >>> factory.description 'Klassier' >>> factory2.title 'Func' >>> factory2.description 'Function' >>> factory3.title 'Func' >>> factory3.description 'Function' Provided Interfaces ~~~~~~~~~~~~~~~~~~~ >>> implemented = factory.getInterfaces() >>> implemented.isOrExtends(IKlass) True >>> list(implemented) [] >>> implemented2 = factory2.getInterfaces() >>> list(implemented2) [] >>> implemented3 = factory3.getInterfaces() >>> list(implemented3) [] The Component Architecture Factory API -------------------------------------- >>> import zope.component >>> factory = Factory(Klass, 'Klass', 'Klassier') >>> gsm = zope.component.getGlobalSiteManager() >>> from zope.component.interfaces import IFactory >>> gsm.registerUtility(factory, IFactory, 'klass') Creating an Object ~~~~~~~~~~~~~~~~~~ >>> kl = zope.component.createObject('klass', 1, 2, foo=3, bar=4) >>> isinstance(kl, Klass) True >>> kl.args (1, 2) >>> kl.kw {'foo': 3, 'bar': 4} Accessing Provided Interfaces ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ >>> implemented = zope.component.getFactoryInterfaces('klass') >>> implemented.isOrExtends(IKlass) True >>> [iface for iface in implemented] [] List of All Factories ~~~~~~~~~~~~~~~~~~~~~ >>> [(name, fac.__class__) for name, fac in ... zope.component.getFactoriesFor(IKlass)] [(u'klass', )] Component-Management objects ============================ Component-management objects provide a higher-level component-management API over the basic adapter-registration API provided by the zope.interface package. In particular, it provides: - utilities - support for computing adapters, rather than just looking up adapter factories. - management of registration comments The zope.component.registry.Components class provides an implementation of zope.component.interfaces.IComponents that provides these features. >>> from zope.component import registry >>> from zope.component import tests >>> components = registry.Components('comps') As components are registered, events are generated. Let's register an event subscriber, so we can see the events generated: >>> import zope.event >>> def logevent(event): ... print event >>> zope.event.subscribers.append(logevent) Utilities --------- You can register Utilities using registerUtility: >>> components.registerUtility(tests.U1(1)) Registered event: UtilityRegistration(, I1, u'', 1, None, u'') Here we didn't specify an interface or name. An unnamed utility was registered for interface I1, since that is only interface implemented by the U1 class: >>> components.getUtility(tests.I1) U1(1) You can also register a utility using a factory instead of a utility instance: >>> def factory(): ... return tests.U1(1) >>> components.registerUtility(factory=factory) Unregistered event: UtilityRegistration(, I1, u'', 1, None, u'') Registered event: UtilityRegistration(, I1, u'', 1, >, u'') If a component implements other than one interface or no interface, then an error will be raised: >>> components.registerUtility(tests.U12(2)) ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... TypeError: The utility doesn't provide a single interface and no provided interface was specified. >>> components.registerUtility(tests.A) ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... TypeError: The utility doesn't provide a single interface and no provided interface was specified. We can provide an interface if desired: >>> components.registerUtility(tests.U12(2), tests.I2) Registered event: UtilityRegistration(, I2, u'', 2, None, u'') and we can specify a name: >>> components.registerUtility(tests.U12(3), tests.I2, u'three') Registered event: UtilityRegistration(, I2, u'three', 3, None, u'') >>> components.getUtility(tests.I2) U12(2) >>> components.getUtility(tests.I2, 'three') U12(3) If you try to get a utility that doesn't exist, you'll get a component lookup error: >>> components.getUtility(tests.I3) ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: (, u'') Unless you use queryUtility: >>> components.queryUtility(tests.I3) >>> components.queryUtility(tests.I3, default=42) 42 You can get information about registered utilities with the registeredUtilities method: >>> for registration in sorted(components.registeredUtilities()): ... print registration.provided, registration.name ... print registration.component, registration.info U1(1) U12(2) three U12(3) Duplicate registrations replace existing ones: >>> components.registerUtility(tests.U1(4), info=u'use 4 now') Unregistered event: UtilityRegistration(, I1, u'', 1, >, u'') Registered event: UtilityRegistration(, I1, u'', 4, None, u'use 4 now') >>> components.getUtility(tests.I1) U1(4) >>> for registration in sorted(components.registeredUtilities()): ... print registration.provided, registration.name ... print registration.component, registration.info U1(4) use 4 now U12(2) three U12(3) As shown in the this example, you can provide an "info" argumemnt when registering utilities. This provides extra documentation about the registration itself that is shown when listing registrations. You can also unregister utilities: >>> components.unregisterUtility(provided=tests.I1) Unregistered event: UtilityRegistration(, I1, u'', 4, None, u'use 4 now') True A boolean is returned indicating whether anything changed: >>> components.queryUtility(tests.I1) >>> for registration in sorted(components.registeredUtilities()): ... print registration.provided, registration.name ... print registration.component, registration.info U12(2) three U12(3) When you unregister, you can specify a component. If the component doesn't match the one registered, then nothing happens: >>> u5 = tests.U1(5) >>> components.registerUtility(u5) Registered event: UtilityRegistration(, I1, u'', 5, None, u'') >>> components.unregisterUtility(tests.U1(6)) False >>> components.queryUtility(tests.I1) U1(5) >>> components.unregisterUtility(u5) Unregistered event: UtilityRegistration(, I1, u'', 5, None, u'') True >>> components.queryUtility(tests.I1) You can get the name and utility for all of the utilities that provide an interface using getUtilitiesFor: >>> sorted(components.getUtilitiesFor(tests.I2)) [(u'', U12(2)), (u'three', U12(3))] getAllUtilitiesRegisteredFor is similar to getUtilitiesFor except that it includes utilities that are overridden. For example, we'll register a utility that for an extending interface of I2: >>> util = tests.U('ext') >>> components.registerUtility(util, tests.I2e) Registered event: UtilityRegistration(, I2e, u'', ext, None, u'') We don't get the new utility for getUtilitiesFor: >>> sorted(components.getUtilitiesFor(tests.I2)) [(u'', U12(2)), (u'three', U12(3))] but we do get it from getAllUtilitiesRegisteredFor: >>> sorted(map(str, components.getAllUtilitiesRegisteredFor(tests.I2))) ['U(ext)', 'U12(2)', 'U12(3)'] Removing a utility also makes it disappear from getUtilitiesFor: >>> components.unregisterUtility(util, tests.I2e) Unregistered event: UtilityRegistration(, I2e, u'', ext, None, u'') True >>> list(components.getAllUtilitiesRegisteredFor(tests.I2e)) [] Adapters -------- You can register adapters with registerAdapter: >>> components.registerAdapter(tests.A12_1) Registered event: AdapterRegistration(, [I1, I2], IA1, u'', A12_1, u'') Here, we didn't specify required interfaces, a provided interface, or a name. The required interfaces were determined from the factory s __component_adapts__ attribute and the provided interface was determined by introspecting what the factory implements. >>> components.getMultiAdapter((tests.U1(6), tests.U12(7)), tests.IA1) A12_1(U1(6), U12(7)) If a factory implements more than one interface, an exception will be raised: >>> components.registerAdapter(tests.A1_12) ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ...

They depend on being dispatched to by the object-event dispatcher: >>> from zope import component >>> import zope.component.event >>> zope.component.getGlobalSiteManager().registerHandler( ... zope.component.event.objectEventNotify) ... # doctest: +NORMALIZE_WHITESPACE Registered event: HandlerRegistration(, [IObjectEvent], u'', objectEventNotify, u'') To see this, we'll first register a multi-handler to show is when handlers are called on 2 objects: >>> @zope.component.adapter(None, None) ... def double_handler(o1, o2): ... print 'Double dispatch:' ... print ' ', o1 ... print ' ', o2 >>> zope.component.getGlobalSiteManager().registerHandler(double_handler) ... # doctest: +NORMALIZE_WHITESPACE Double dispatch: HandlerRegistration(, [Interface, Interface], u'', double_handler, u'') Registered event: HandlerRegistration(, [Interface, Interface], u'', double_handler, u'') Registered event: HandlerRegistration(, [Interface, Interface], u'', double_handler, u'') In the example above, the double_handler reported it's own registration. :) Now we'll register our handlers: >>> zope.component.getGlobalSiteManager().registerHandler( ... registry.dispatchUtilityRegistrationEvent) ... # doctest: +NORMALIZE_WHITESPACE +ELLIPSIS Double dispatch: ... >>> zope.component.getGlobalSiteManager().registerHandler( ... registry.dispatchAdapterRegistrationEvent) ... # doctest: +NORMALIZE_WHITESPACE +ELLIPSIS Double dispatch: ... >>> zope.component.getGlobalSiteManager().registerHandler( ... registry.dispatchSubscriptionAdapterRegistrationEvent) ... # doctest: +NORMALIZE_WHITESPACE +ELLIPSIS Double dispatch: ... >>> zope.component.getGlobalSiteManager().registerHandler( ... registry.dispatchHandlerRegistrationEvent) ... # doctest: +NORMALIZE_WHITESPACE Double dispatch: HandlerRegistration(, [IHandlerRegistration, IRegistrationEvent], u'', dispatchHandlerRegistrationEvent, u'') Registered event: HandlerRegistration(, [IHandlerRegistration, IRegistrationEvent], u'', dispatchHandlerRegistrationEvent, u'') Double dispatch: Registered event: HandlerRegistration(, [IHandlerRegistration, IRegistrationEvent], u'', dispatchHandlerRegistrationEvent, u'') Registered event: HandlerRegistration(, [IHandlerRegistration, IRegistrationEvent], u'', dispatchHandlerRegistrationEvent, u'') In the last example above, we can see that the registration of dispatchHandlerRegistrationEvent was handled by dispatchHandlerRegistrationEvent and redispatched. This can be seen in the second double-dispatch output, where the first argument is the object being registered, which is dispatchHandlerRegistrationEvent. If we change some other registrations, we can the double dispatch taking place: >>> components.registerUtility(u5) ... # doctest: +NORMALIZE_WHITESPACE Double dispatch: UtilityRegistration(, I1, u'', 5, None, u'') Registered event: UtilityRegistration(, I1, u'', 5, None, u'') Double dispatch: U1(5) Registered event: UtilityRegistration(, I1, u'', 5, None, u'') Registered event: UtilityRegistration(, I1, u'', 5, None, u'') >>> components.registerAdapter(tests.A12_1) ... # doctest: +NORMALIZE_WHITESPACE Double dispatch: AdapterRegistration(, [I1, I2], IA1, u'', A12_1, u'') Registered event: AdapterRegistration(, [I1, I2], IA1, u'', A12_1, u'') Double dispatch: zope.component.tests.A12_1 Registered event: AdapterRegistration(, [I1, I2], IA1, u'', A12_1, u'') Registered event: AdapterRegistration(, [I1, I2], IA1, u'', A12_1, u'') >>> components.registerSubscriptionAdapter(tests.A1_2) ... # doctest: +NORMALIZE_WHITESPACE Double dispatch: SubscriptionRegistration(, [I1], IA2, u'', A1_2, u'') Registered event: SubscriptionRegistration(, [I1], IA2, u'', A1_2, u'') Double dispatch: zope.component.tests.A1_2 Registered event: SubscriptionRegistration(, [I1], IA2, u'', A1_2, u'') Registered event: SubscriptionRegistration(, [I1], IA2, u'', A1_2, u'') Persistent Component Management =============================== Persistent component management allows persistent management of components. From a usage point of view, there shouldn't be any new behavior beyond what's described in registry.txt. The Zope 3 Component Architecture (Socket Example) ================================================== The component architecture provides an application framework that provides its functionality through loosely-connected components. A *component* can be any Python object and has a particular purpose associated with it. Thus, in a component-based applications you have many small component in contrast to classical object-oriented development, where you have a few big objects. Components communicate via specific APIs, which are formally defined by interfaces, which are provided by the `zope.interface` package. *Interfaces* describe the methods and properties that a component is expected to provide. They are also used as a primary mean to provide developer-level documentation for the components. For more details about interfaces see `zope/interface/README.txt`. The two main types of components are *adapters* and *utilities*. They will be discussed in detail later in this document. Both component types are managed by the *site manager*, with which you can register and access these components. However, most of the site manager's functionality is hidden behind the component architecture's public API, which is documented in `IComponentArchitecture`. Adapters -------- Adapters are a well-established pattern. An *adapter* uses an object providing one interface to produce an object that provides another interface. Here an example: Imagine that you purchased an electric shaver in the US, and thus you require the US socket type. You are now traveling in Germany, where another socket style is used. You will need a device, an adapter, that converts from the German to the US socket style. The functionality of adapters is actually natively provided by the `zope.interface` package and is thus well documented there. The `human.txt` file provides a gentle introduction to adapters, whereby `adapter.txt` is aimed at providing a comprehensive insight into adapters, but is too abstract for many as an initial read. Thus, we will only explain adapters in the context of the component architecture's API. So let's say that we have a German socket >>> from zope.interface import Interface, implements >>> class IGermanSocket(Interface): ... pass >>> class Socket(object): ... def __repr__(self): ... return '' %self.__class__.__name__ >>> class GermanSocket(Socket): ... """German wall socket.""" ... implements(IGermanSocket) and we want to convert it to an US socket >>> class IUSSocket(Interface): ... pass so that our shaver can be used in Germany. So we go to a German electronics store to look for an adapter that we can plug in the wall: >>> class GermanToUSSocketAdapter(Socket): ... implements(IUSSocket) ... __used_for__ = IGermanSocket ... ... def __init__(self, socket): ... self.context = socket Note that I could have called the passed in socket any way I like, but `context` is the standard name accepted. Single Adapters ~~~~~~~~~~~~~~~ Before we can use the adapter, we have to buy it and make it part of our inventory. In the component architecture we do this by registering the adapter with the framework, more specifically with the global site manager: >>> import zope.component >>> gsm = zope.component.getGlobalSiteManager() >>> gsm.registerAdapter(GermanToUSSocketAdapter, (IGermanSocket,), IUSSocket) `zope.component` is the component architecture API that is being presented by this file. You registered an adapter from `IGermanSocket` to `IUSSocket` having no name (thus the empty string). Anyways, you finally get back to your hotel room and shave, since you have not been able to shave in the plane. In the bathroom you discover a socket: >>> bathroomDE = GermanSocket() >>> IGermanSocket.providedBy(bathroomDE) True You now insert the adapter in the German socket >>> bathroomUS = zope.component.getAdapter(bathroomDE, IUSSocket, '') so that the socket now provides the US version: >>> IUSSocket.providedBy(bathroomUS) True Now you can insert your shaver and get on with your day. After a week you travel for a couple of days to the Prague and you notice that the Czech have yet another socket type: >>> class ICzechSocket(Interface): ... pass >>> class CzechSocket(Socket): ... implements(ICzechSocket) >>> czech = CzechSocket() You try to find an adapter for your shaver in your bag, but you fail, since you do not have one: >>> zope.component.getAdapter(czech, IUSSocket, '') \ ... #doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: (, , '') or the more graceful way: >>> marker = object() >>> socket = zope.component.queryAdapter(czech, IUSSocket, '', marker) >>> socket is marker True In the component architecture API any `get*` method will fail with a specific exception, if a query failed, whereby methods starting with `query*` will always return a `default` value after a failure. Named Adapters ~~~~~~~~~~~~~~ You are finally back in Germany. You also brought your DVD player and a couple DVDs with you, which you would like to watch. Your shaver was able to convert automatically from 110 volts to 240 volts, but your DVD player cannot. So you have to buy another adapter that also handles converting the voltage and the frequency of the AC current: >>> class GermanToUSSocketAdapterAndTransformer(object): ... implements(IUSSocket) ... __used_for__ = IGermanSocket ... ... def __init__(self, socket): ... self.context = socket Now, we need a way to keep the two adapters apart. Thus we register them with a name: >>> gsm.registerAdapter(GermanToUSSocketAdapter, ... (IGermanSocket,), IUSSocket, 'shaver',) >>> gsm.registerAdapter(GermanToUSSocketAdapterAndTransformer, ... (IGermanSocket,), IUSSocket, 'dvd') Now we simply look up the adapters using their labels (called *name*): >>> socket = zope.component.getAdapter(bathroomDE, IUSSocket, 'shaver') >>> socket.__class__ is GermanToUSSocketAdapter True >>> socket = zope.component.getAdapter(bathroomDE, IUSSocket, 'dvd') >>> socket.__class__ is GermanToUSSocketAdapterAndTransformer True Clearly, we do not have an adapter for the MP3 player >>> zope.component.getAdapter(bathroomDE, IUSSocket, 'mp3') \ ... #doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: (, , 'mp3') but you could use the 'dvd' adapter in this case of course. ;) Sometimes you want to know all adapters that are available. Let's say you want to know about all the adapters that convert a German to a US socket type: >>> sockets = list(zope.component.getAdapters((bathroomDE,), IUSSocket)) >>> len(sockets) 3 >>> names = [name for name, socket in sockets] >>> names.sort() >>> names [u'', u'dvd', u'shaver'] `zope.component.getAdapters()` returns a list of tuples. The first entry of the tuple is the name of the adapter and the second is the adapter itself. Multi-Adapters ~~~~~~~~~~~~~~ After watching all the DVDs you brought at least twice, you get tired of them and you want to listen to some music using your MP3 player. But darn, the MP3 player plug has a ground pin and all the adapters you have do not support that: >>> class IUSGroundedSocket(IUSSocket): ... pass So you go out another time to buy an adapter. This time, however, you do not buy yet another adapter, but a piece that provides the grounding plug: >>> class IGrounder(Interface): ... pass >>> class Grounder(object): ... implements(IGrounder) ... def __repr__(self): ... return '' Then together they will provided a grounded us socket: >>> class GroundedGermanToUSSocketAdapter(object): ... implements(IUSGroundedSocket) ... __used_for__ = (IGermanSocket, IGrounder) ... def __init__(self, socket, grounder): ... self.socket, self.grounder = socket, grounder You now register the combination, so that you know you can create a `IUSGroundedSocket`: >>> gsm.registerAdapter(GroundedGermanToUSSocketAdapter, ... (IGermanSocket, IGrounder), IUSGroundedSocket, 'mp3') Given the grounder >>> grounder = Grounder() and a German socket >>> livingroom = GermanSocket() we can now get a grounded US socket: >>> socket = zope.component.getMultiAdapter((livingroom, grounder), ... IUSGroundedSocket, 'mp3') >>> socket.__class__ is GroundedGermanToUSSocketAdapter True >>> socket.socket is livingroom True >>> socket.grounder is grounder True Of course, you do not have a 'dvd' grounded US socket available: >>> zope.component.getMultiAdapter((livingroom, grounder), ... IUSGroundedSocket, 'dvd') \ ... #doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: ((, ), , 'dvd') >>> socket = zope.component.queryMultiAdapter( ... (livingroom, grounder), IUSGroundedSocket, 'dvd', marker) >>> socket is marker True Again, you might want to read `adapter.txt` in `zope.interface` for a more comprehensive coverage of multi-adapters. Subscribers ----------- While subscribers are directly supported by the adapter registry and are adapters for all theoretical purposes, practically it might be better to think of them as separate components. Subscribers are particularly useful for events. Let's say one of our adapters overheated and caused a small fire: >>> class IFire(Interface): ... pass >>> class Fire(object): ... implements(IFire) >>> fire = Fire() We want to use all available objects to put out the fire: >>> class IFireExtinguisher(Interface): ... def extinguish(): ... pass >>> class FireExtinguisher(object): ... def __init__(self, fire): ... pass ... def extinguish(self): ... "Place extinguish code here." ... print 'Used ' + self.__class__.__name__ + '.' Here some specific methods to put out the fire: >>> class PowderExtinguisher(FireExtinguisher): ... pass >>> gsm.registerSubscriptionAdapter(PowderExtinguisher, ... (IFire,), IFireExtinguisher) >>> class Blanket(FireExtinguisher): ... pass >>> gsm.registerSubscriptionAdapter(Blanket, (IFire,), IFireExtinguisher) >>> class SprinklerSystem(FireExtinguisher): ... pass >>> gsm.registerSubscriptionAdapter(SprinklerSystem, ... (IFire,), IFireExtinguisher) Now let use all these things to put out the fire: >>> extinguishers = zope.component.subscribers((fire,), IFireExtinguisher) >>> extinguishers.sort() >>> for extinguisher in extinguishers: ... extinguisher.extinguish() Used Blanket. Used PowderExtinguisher. Used SprinklerSystem. If no subscribers are found for a particular object, then an empty list is returned: >>> zope.component.subscribers((object(),), IFireExtinguisher) [] Utilities --------- Utilities are the second type of component, the component architecture implements. *Utilities* are simply components that provide an interface. When you register an utility, you always register an instance (in contrast to a factory for adapters) since the initialization and setup process of a utility might be complex and is not well defined. In some ways a utility is much more fundamental than an adapter, because an adapter cannot be used without another component, but a utility is always self-contained. I like to think of utilities as the foundation of your application and adapters as components extending beyond this foundation. Back to our story... After your vacation is over you fly back home to Tampa, Florida. But it is August now, the middle of the Hurricane season. And, believe it or not, you are worried that you will not be able to shave when the power goes out for several days. (You just hate wet shavers.) So you decide to go to your favorite hardware store and by a Diesel-powered electric generator. The generator provides of course a US-style socket: >>> class Generator(object): ... implements(IUSSocket) ... def __repr__(self): ... return '' >>> generator = Generator() Like for adapters, we now have to add the newly-acquired generator to our inventory by registering it as a utility: >>> gsm.registerUtility(generator, IUSSocket) We can now get the utility using >>> utility = zope.component.getUtility(IUSSocket) >>> utility is generator True As you can see, it is very simple to register and retrieve utilities. If a utility does not exist for a particular interface, such as the German socket, then the lookup fails >>> zope.component.getUtility(IGermanSocket) Traceback (most recent call last): ... ComponentLookupError: (, '') or more gracefully when specifying a default value: >>> default = object() >>> utility = zope.component.queryUtility(IGermanSocket, default=default) >>> utility is default True Note: The only difference between `getUtility()` and `queryUtility()` is the fact that you can specify a default value for the latter function, so that it will never cause a `ComponentLookupError`. Named Utilities ~~~~~~~~~~~~~~~ It is often desirable to have several utilities providing the same interface per site. This way you can implement any sort of registry using utilities. For this reason, utilities -- like adapters -- can be named. In the context of our story, we might want to do the following: You really do not trust gas stations either. What if the roads are blocked after a hurricane and the gas stations run out of oil. So you look for another renewable power source. Then you think about solar panels! After a storm there is usually very nice weather, so why not? Via the Web you order a set of 110V/120W solar panels that provide a regular US-style socket as output: >>> class SolarPanel(object): ... implements(IUSSocket) ... def __repr__(self): ... return '' >>> panel = SolarPanel() Once it arrives, we add it to our inventory: >>> gsm.registerUtility(panel, IUSSocket, 'Solar Panel') You can now access the solar panel using >>> utility = zope.component.getUtility(IUSSocket, 'Solar Panel') >>> utility is panel True Of course, if a utility is not available, then the lookup will simply fail >>> zope.component.getUtility(IUSSocket, 'Wind Mill') Traceback (most recent call last): ... ComponentLookupError: (, 'Wind Mill') or more gracefully when specifying a default value: >>> default = object() >>> utility = zope.component.queryUtility(IUSSocket, 'Wind Mill', ... default=default) >>> utility is default True Now you want to look at all the utilities you have for a particular kind. The following API function will return a list of name/utility pairs: >>> utils = list(zope.component.getUtilitiesFor(IUSSocket)) >>> utils.sort() >>> utils #doctest: +NORMALIZE_WHITESPACE [(u'', ), (u'Solar Panel', )] Another method of looking up all utilities is by using `getAllUtilitiesRegisteredFor(iface)`. This function will return an iterable of utilities (without names); however, it will also return overridden utilities. If you are not using multiple site managers, you will not actually need this method. >>> utils = list(zope.component.getAllUtilitiesRegisteredFor(IUSSocket)) >>> utils.sort() >>> utils [, ] Factories ~~~~~~~~~ A *factory* is a special kind of utility that exists to create other components. A factory is always identified by a name. It also provides a title and description and is able to tell the developer what interfaces the created object will provide. The advantage of using a factory to create an object instead of directly instantiating a class or executing any other callable is that we can refer to the factory by name. As long as the name stays fixed, the implementation of the callable can be renamed or moved without a breakage in code. Let's say that our solar panel comes in parts and they have to be assembled. This assembly would be done by a factory, so let's create one for the solar panel. To do this, we can use a standard implementation of the `IFactory` interface: >>> from zope.component.factory import Factory >>> factory = Factory(SolarPanel, ... 'Solar Panel', ... 'This factory creates a solar panel.') Optionally, I could have also specified the interfaces that the created object will provide, but the factory class is smart enough to determine the implemented interface from the class. We now register the factory: >>> from zope.component.interfaces import IFactory >>> gsm.registerUtility(factory, IFactory, 'SolarPanel') We can now get a list of interfaces the produced object will provide: >>> ifaces = zope.component.getFactoryInterfaces('SolarPanel') >>> IUSSocket in ifaces True By the way, this is equivalent to >>> ifaces2 = factory.getInterfaces() >>> ifaces is ifaces2 True Of course you can also just create an object: >>> panel = zope.component.createObject('SolarPanel') >>> panel.__class__ is SolarPanel True Note: Ignore the first argument (`None`) for now; it is the context of the utility lookup, which is usually an optional argument, but cannot be in this case, since all other arguments beside the `name` are passed in as arguments to the specified callable. Once you register several factories >>> gsm.registerUtility(Factory(Generator), IFactory, 'Generator') you can also determine, which available factories will create objects providing a certain interface: >>> factories = zope.component.getFactoriesFor(IUSSocket) >>> factories = [(name, factory.__class__) for name, factory in factories] >>> factories.sort() >>> factories #doctest: +NORMALIZE_WHITESPACE [(u'Generator', ), (u'SolarPanel', )] Site Managers ------------- Why do we need site managers? Why is the component architecture API not sufficient? Some applications, including Zope 3, have a concept of locations. It is often desirable to have different configurations for these location; this can be done by overwriting existing or adding new component registrations. Site managers in locations below the root location, should be able to delegate requests to their parent locations. The root site manager is commonly known as *global site manager*, since it is always available. You can always get the global site manager using the API: >>> gsm = zope.component.getGlobalSiteManager() >>> from zope.component import globalSiteManager >>> gsm is globalSiteManager True >>> from zope.component.interfaces import IComponentLookup >>> IComponentLookup.providedBy(gsm) True >>> from zope.component.interfaces import IComponents >>> IComponents.providedBy(gsm) True You can also lookup at site manager in a given context. The only requirement is that the context can be adapted to a site manager. So let's create a special site manager: >>> from zope.component.globalregistry import BaseGlobalComponents >>> sm = BaseGlobalComponents() Now we create a context that adapts to the site manager via the `__conform__` method as specified in PEP 246. >>> class Context(object): ... def __init__(self, sm): ... self.sm = sm ... def __conform__(self, interface): ... if interface.isOrExtends(IComponentLookup): ... return self.sm We now instantiate the `Context` with our special site manager: >>> context = Context(sm) >>> context.sm is sm True We can now ask for the site manager of this context: >>> lsm = zope.component.getSiteManager(context) >>> lsm is sm True The site manager instance `lsm` is formally known as a *local site manager* of `context`. CHANGES ******* 3.9.5 (2010-07-09) ================== - Fix test requirements specification. 3.9.4 (2010-04-30) ================== - Prefer the standard libraries doctest module to the one from zope.testing. 3.9.3 (2010-03-08) ================== - The ZCML directives provided by zope.component now register the components in the registry returned by getSiteManager instead of the global registry. This allows the hooking of the getSiteManager method before the load of a ZCML file to register the components in a custom registry. 3.9.2 (2010-01-22) ================== - Fixed a bug introduced by recent refactoring, where passing CheckerPublic to securityAdapterFactory wrongly wrapped the factory into a LocatingUntrustedAdapterFactory. 3.9.1 (2010-01-21) ================== - The tested testrunner somehow gets influenced by options of the outer testrunner, such a the -v option. We modified the tests so that it avoids this. 3.9.0 (2010-01-21) ================== - Add testlayer support. It is now possible to load a ZCML file within tests more easily. See zope.component.testlayer.py and zope.component.testlayer.txt. 3.8.0 (2009-11-16) ================== - Removed the dependencies on zope.proxy and zope.security from the zcml extra: zope.component does not hard depend on them anymore; the support for security proxied components ZCML registrations is enabled only if zope.security and zope.proxy are available. - Moved the IPossibleSite and ISite interfaces here from zope.location as they are dealing with zope.component's concept of a site, but not with location. - Moved the zope.site.hooks functionality to zope.component.hooks as it isn't actually dealing with zope.site's concept of a site. 3.7.1 (2009-07-24) ================== - Fixed a problem, where ``queryNextUtility`` could fail if the context could not be adapted to a ``IComponentLookup``. - Fixed 2 related bugs: When a utility is registered and there was previously a utility registered for the same interface and name, then the old utility is unregistered. The 2 bugs related to this: - There was no ``Unregistered`` for the implicit unregistration. Now there is. - The old utility was still held and returned by getAllUtilitiesRegisteredFor. In other words, it was still considered registered, eeven though it wasn't. A particularly negative consequence of this is that the utility is held in memory or in the database even though it isn't used. 3.7.0 (2009-05-21) ================== - The HookableTests were not run by the testrunner. - Add in zope:view and zope:resource implementations into zope.component.zcml (dependency loaded with zope.component [zcml]). 3.6.0 (2009-03-12) ================== - IMPORTANT: the interfaces that were defined in the zope.component.bbb.interfaces and deprecated for years are now (re)moved. However, some packages, including part of zope framework were still using those interfaces. They will be adapted for this change. If you were using some of those interfaces, you need to adapt your code as well: - The IView and IDefaultViewName were moved to zope.publisher.interfaces. - The IResource was moved to zope.app.publisher.interfaces. - IContextDependent, IPresentation, IPresentationRequest, IResourceFactory, IViewFactory were removed completely. If you used IViewFactory in context of zope.app.form, there's now IWidgetFactory in the zope.app.form.interfaces instead. - Add getNextUtility/queryNextUtility functions that used to be in zope.site earlier (and in zope.app.component even more earlier). - Added a pure-Python 'hookable' implementation, for use when 'zope.hookable' is not present. - Removed use of 'zope.deferredimport' by breaking import cycles. - Cleanup package documentation and changelog a bit. Add sphinx-based documentation building command to the buildout. - Remove deprecated code. - Change package's mailing list address to zope-dev at zope.org, because zope3-dev at zope.org is now retired. 3.5.1 (2008-07-25) ================== - Fix bug introduced in 3.5.0: no longer supported interfaces declared in Python and always wanted an explicit provides="..." attribute. https://bugs.launchpad.net/zope3/+bug/251865 3.5.0 (2008-07-25) ================== - Support registration of utilities via factories through the component registry and return factory information in the registration information. This fixes https://bugs.launchpad.net/zope3/+bug/240631 - Optimized un/registerUtility via storing an optimized data structure for efficient retrieval of already registered utilities. This avoids looping over all utilities when registering a new one. 3.4.0 (2007-09-29) ================== No further changes since 3.4.0a1. 3.4.0a1 (2007-04-22) ==================== Corresponds to zope.component from Zope 3.4.0a1. - In the Zope 3.3.x series, ``zope.component`` was simplified yet once more. See http://wiki.zope.org/zope3/LocalComponentManagementSimplification for the proposal describing the changes. 3.2.0.2 (2006-04-15) ==================== - Fix packaging bug: 'package_dir' must be a *relative* path. 3.2.0.1 (2006-04-14) ==================== - Packaging change: suppress inclusion of 'setup.cfg' in 'sdist' builds. 3.2.0 (2006-01-05) ================== Corresponds to the verison of the zope.component package shipped as part of the Zope 3.2.0 release. - Deprecated services and related APIs. The adapter and utility registries are now available directly via the site manager's 'adapters' and 'utilities' attributes, respectively. Services are accessible, but deprecated, and will be removed in Zope 3.3. - Deprectaed all presentation-related APIs, including all view-related API functions. Use the adapter API functions instead. See http://dev.zope.org/Zope3/ImplementViewsAsAdapters` - Deprecated 'contextdependent' package: site managers are now looked up via a thread global, set during URL traversal. The 'context' argument is now always optional, and should no longer be passed. 3.0.0 (2004-11-07) ================== Corresponds to the verison of the zope.component package shipped as part of the Zope X3.0.0 release.

It is maintained by the* `Zope Toolkit project `_. This package represents the core of the Zope Component Architecture. Together with the 'zope.interface' package, it provides facilities for defining, registering and looking up components. .. contents:: Detailed Documentation ********************** Zope Component Architecture =========================== This package, together with `zope.interface`, provides facilities for defining, registering and looking up components. There are two basic kinds of components: adapters and utilities. Utilities --------- Utilities are just components that provide an interface and that are looked up by an interface and a name. Let's look at a trivial utility definition: >>> from zope import interface >>> class IGreeter(interface.Interface): ... def greet(): ... "say hello" >>> class Greeter: ... interface.implements(IGreeter) ... ... def __init__(self, other="world"): ... self.other = other ... ... def greet(self): ... print "Hello", self.other We can register an instance this class using `provideUtility` [1]_: >>> from zope import component >>> greet = Greeter('bob') >>> component.provideUtility(greet, IGreeter, 'robert') In this example we registered the utility as providing the `IGreeter` interface with a name of 'bob'. We can look the interface up with either `queryUtility` or `getUtility`: >>> component.queryUtility(IGreeter, 'robert').greet() Hello bob >>> component.getUtility(IGreeter, 'robert').greet() Hello bob `queryUtility` and `getUtility` differ in how failed lookups are handled: >>> component.queryUtility(IGreeter, 'ted') >>> component.queryUtility(IGreeter, 'ted', 42) 42 >>> component.getUtility(IGreeter, 'ted') ... # doctest: +ELLIPSIS Traceback (most recent call last): ... ComponentLookupError: (, 'ted') If a component provides only one interface, as in the example above, then we can omit the provided interface from the call to `provideUtility`: >>> ted = Greeter('ted') >>> component.provideUtility(ted, name='ted') >>> component.queryUtility(IGreeter, 'ted').greet() Hello ted The name defaults to an empty string: >>> world = Greeter() >>> component.provideUtility(world) >>> component.queryUtility(IGreeter).greet() Hello world Adapters -------- Adapters are components that are computed from other components to adapt them to some interface. Because they are computed from other objects, they are provided as factories, usually classes. Here, we'll create a greeter for persons, so we can provide personalized greetings for different people: >>> class IPerson(interface.Interface): ... name = interface.Attribute("Name") >>> class PersonGreeter: ... ... component.adapts(IPerson) ... interface.implements(IGreeter) ... ... def __init__(self, person): ... self.person = person ... ... def greet(self): ... print "Hello", self.person.name The class defines a constructor that takes an argument for every object adapted. We used `component.adapts` to declare what we adapt. We can find out if an object declares that it adapts anything using adaptedBy: >>> list(component.adaptedBy(PersonGreeter)) == [IPerson] True If an object makes no declaration, then None is returned: >>> component.adaptedBy(Greeter()) is None True If we declare the interfaces adapted and if we provide only one interface, as in the example above, then we can provide the adapter very simply [1]_: >>> component.provideAdapter(PersonGreeter) For adapters that adapt a single interface to a single interface without a name, we can get the adapter by simply calling the interface: >>> class Person: ... interface.implements(IPerson) ... ... def __init__(self, name): ... self.name = name >>> IGreeter(Person("Sally")).greet() Hello Sally We can also provide arguments to be very specific about what how to register the adapter. >>> class BobPersonGreeter(PersonGreeter): ... name = 'Bob' ... def greet(self): ... print "Hello", self.person.name, "my name is", self.name >>> component.provideAdapter( ... BobPersonGreeter, [IPerson], IGreeter, 'bob') The arguments can also be provided as keyword arguments: >>> class TedPersonGreeter(BobPersonGreeter): ... name = "Ted" >>> component.provideAdapter( ... factory=TedPersonGreeter, adapts=[IPerson], ... provides=IGreeter, name='ted') For named adapters, use `queryAdapter`, or `getAdapter`: >>> component.queryAdapter(Person("Sally"), IGreeter, 'bob').greet() Hello Sally my name is Bob >>> component.getAdapter(Person("Sally"), IGreeter, 'ted').greet() Hello Sally my name is Ted If an adapter can't be found, `queryAdapter` returns a default value and `getAdapter` raises an error: >>> component.queryAdapter(Person("Sally"), IGreeter, 'frank') >>> component.queryAdapter(Person("Sally"), IGreeter, 'frank', 42) 42 >>> component.getAdapter(Person("Sally"), IGreeter, 'frank') ... # doctest: +ELLIPSIS Traceback (most recent call last): ... ComponentLookupError: (...Person...>, <...IGreeter>, 'frank') Adapters can adapt multiple objects: >>> class TwoPersonGreeter: ... ... component.adapts(IPerson, IPerson) ... interface.implements(IGreeter) ... ... def __init__(self, person, greeter): ... self.person = person ... self.greeter = greeter ... ... def greet(self): ... print "Hello", self.person.name ... print "my name is", self.greeter.name >>> component.provideAdapter(TwoPersonGreeter) To look up a multi-adapter, use either `queryMultiAdapter` or `getMultiAdapter`: >>> component.queryMultiAdapter((Person("Sally"), Person("Bob")), ... IGreeter).greet() Hello Sally my name is Bob Adapters need not be classes. Any callable will do. We use the adapter decorator (in the Python 2.4 decorator sense) to declare that a callable object adapts some interfaces (or classes): >>> class IJob(interface.Interface): ... "A job" >>> class Job: ... interface.implements(IJob) >>> def personJob(person): ... return getattr(person, 'job', None) >>> personJob = interface.implementer(IJob)(personJob) >>> personJob = component.adapter(IPerson)(personJob) In Python 2.4, the example can be written: >>> @interface.implementer(IJob) ... @component.adapter(IPerson) ... def personJob(person): ... return getattr(person, 'job', None) which looks a bit nicer. In this example, the personJob function simply returns the person's `job` attribute if present, or None if it's not present. An adapter factory can return None to indicate that adaptation wasn't possible. Let's register this adapter and try it out: >>> component.provideAdapter(personJob) >>> sally = Person("Sally") >>> IJob(sally) # doctest: +ELLIPSIS Traceback (most recent call last): ... TypeError: ('Could not adapt', ... The adaptation failed because sally didn't have a job. Let's give her one: >>> job = Job() >>> sally.job = job >>> IJob(sally) is job True Subscription Adapters --------------------- Unlike regular adapters, subscription adapters are used when we want all of the adapters that adapt an object to a particular adapter. Consider a validation problem. We have objects and we want to assess whether they meet some sort of standards. We define a validation interface: >>> class IValidate(interface.Interface): ... def validate(ob): ... """Determine whether the object is valid ... ... Return a string describing a validation problem. ... An empty string is returned to indicate that the ... object is valid. ... """ Perhaps we have documents: >>> class IDocument(interface.Interface): ... summary = interface.Attribute("Document summary") ... body = interface.Attribute("Document text") >>> class Document: ... interface.implements(IDocument) ... def __init__(self, summary, body): ... self.summary, self.body = summary, body Now, we may want to specify various validation rules for documents. For example, we might require that the summary be a single line: >>> class SingleLineSummary: ... component.adapts(IDocument) ... interface.implements(IValidate) ... ... def __init__(self, doc): ... self.doc = doc ... ... def validate(self): ... if '\n' in self.doc.summary: ... return 'Summary should only have one line' ... else: ... return '' Or we might require the body to be at least 1000 characters in length: >>> class AdequateLength: ... component.adapts(IDocument) ... interface.implements(IValidate) ... ... def __init__(self, doc): ... self.doc = doc ... ... def validate(self): ... if len(self.doc.body) < 1000: ... return 'too short' ... else: ... return '' We can register these as subscription adapters [1]_: >>> component.provideSubscriptionAdapter(SingleLineSummary) >>> component.provideSubscriptionAdapter(AdequateLength) We can then use the subscribers to validate objects: >>> doc = Document("A\nDocument", "blah") >>> [adapter.validate() ... for adapter in component.subscribers([doc], IValidate) ... if adapter.validate()] ['Summary should only have one line', 'too short'] >>> doc = Document("A\nDocument", "blah" * 1000) >>> [adapter.validate() ... for adapter in component.subscribers([doc], IValidate) ... if adapter.validate()] ['Summary should only have one line'] >>> doc = Document("A Document", "blah") >>> [adapter.validate() ... for adapter in component.subscribers([doc], IValidate) ... if adapter.validate()] ['too short'] Handlers -------- Handlers are subscription adapter factories that don't produce anything. They do all of their work when called. Handlers are typically used to handle events. Event subscribers are different from other subscription adapters in that the caller of event subscribers doesn't expect to interact with them in any direct way. For example, an event publisher doesn't expect to get any return value. Because subscribers don't need to provide an API to their callers, it is more natural to define them with functions, rather than classes. For example, in a document-management system, we might want to record creation times for documents: >>> import datetime >>> def documentCreated(event): ... event.doc.created = datetime.datetime.utcnow() In this example, we have a function that takes an event and performs some processing. It doesn't actually return anything. This is a special case of a subscription adapter that adapts an event to nothing. All of the work is done when the adapter "factory" is called. We call subscribers that don't actually create anything "handlers". There are special APIs for registering and calling them. To register the subscriber above, we define a document-created event: >>> class IDocumentCreated(interface.Interface): ... doc = interface.Attribute("The document that was created") >>> class DocumentCreated: ... interface.implements(IDocumentCreated) ... ... def __init__(self, doc): ... self.doc = doc We'll also change our handler definition to: >>> def documentCreated(event): ... event.doc.created = datetime.datetime.utcnow() >>> documentCreated = component.adapter(IDocumentCreated)(documentCreated) Note that in Python 2.4, this can be written: >>> @component.adapter(IDocumentCreated) ... def documentCreated(event): ... event.doc.created = datetime.datetime.utcnow() This marks the handler as an adapter of `IDocumentCreated` events. Now we'll register the handler [1]_: >>> component.provideHandler(documentCreated) Now, if we can create an event and use the `handle` function to call handlers registered for the event: >>> component.handle(DocumentCreated(doc)) >>> doc.created.__class__.__name__ 'datetime' .. [1] CAUTION: This API should only be used from test or application-setup code. This API shouldn't be used by regular library modules, as component registration is a configuration activity. Events ====== The Component Architecture provides a way to dispatch events to event handlers. Event handlers are registered as *subscribers* a.k.a. *handlers*. Before we can start we need to import ``zope.component.event`` to make the dispatching effective: >>> import zope.component.event Consider two event classes: >>> class Event1(object): ... pass >>> class Event2(Event1): ... pass Now consider two handlers for these event classes: >>> called = [] >>> import zope.component >>> @zope.component.adapter(Event1) ... def handler1(event): ... called.append(1) >>> @zope.component.adapter(Event2) ... def handler2(event): ... called.append(2) We can register them with the Component Architecture: >>> zope.component.provideHandler(handler1) >>> zope.component.provideHandler(handler2) Now let's go through the events. We'll see that the handlers have been called accordingly: >>> from zope.event import notify >>> notify(Event1()) >>> called [1] >>> del called[:] >>> notify(Event2()) >>> called.sort() >>> called [1, 2] Object events ------------- The ``objectEventNotify`` function is a subscriber to dispatch ObjectEvents to interested adapters. First create an object class: >>> class IUseless(zope.interface.Interface): ... """Useless object""" >>> class UselessObject(object): ... """Useless object""" ... zope.interface.implements(IUseless) Then create an event class: >>> class IObjectThrownEvent(zope.component.interfaces.IObjectEvent): ... """An object has been thrown away""" >>> class ObjectThrownEvent(zope.component.interfaces.ObjectEvent): ... """An object has been thrown away""" ... zope.interface.implements(IObjectThrownEvent) Create an object and an event: >>> hammer = UselessObject() >>> event = ObjectThrownEvent(hammer) Then notify the event to the subscribers. Since the subscribers list is empty, nothing happens. >>> zope.component.event.objectEventNotify(event) Now create an handler for the event: >>> events = [] >>> def record(*args): ... events.append(args) >>> zope.component.provideHandler(record, [IUseless, IObjectThrownEvent]) The event is notified to the subscriber: >>> zope.component.event.objectEventNotify(event) >>> events == [(hammer, event)] True Following test demonstrates how a subscriber can raise an exception to prevent an action. >>> zope.component.provideHandler(zope.component.event.objectEventNotify) Let's create a container: >>> class ToolBox(dict): ... def __delitem__(self, key): ... notify(ObjectThrownEvent(self[key])) ... return super(ToolBox,self).__delitem__(key) >>> container = ToolBox() And put the object into the container: >>> container['Red Hammer'] = hammer Create an handler function that will raise an error when called: >>> class Veto(Exception): ... pass >>> def callback(item, event): ... assert(item == event.object) ... raise Veto Register the handler: >>> zope.component.provideHandler(callback, [IUseless, IObjectThrownEvent]) Then if we try to remove the object, an ObjectThrownEvent is fired: >>> del container['Red Hammer'] ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... raise Veto Veto Factories ========= The Factory Class ----------------- >>> from zope.interface import Interface >>> class IFunction(Interface): ... pass >>> class IKlass(Interface): ... pass >>> from zope.interface import implements >>> class Klass(object): ... implements(IKlass) ... ... def __init__(self, *args, **kw): ... self.args = args ... self.kw = kw >>> from zope.component.factory import Factory >>> factory = Factory(Klass, 'Klass', 'Klassier') >>> factory2 = Factory(lambda x: x, 'Func', 'Function') >>> factory3 = Factory(lambda x: x, 'Func', 'Function', (IFunction,)) Calling a Factory ~~~~~~~~~~~~~~~~~ Here we test whether the factory correctly creates the objects and including the correct handling of constructor elements. First we create a factory that creates instanace of the `Klass` class: >>> factory = Factory(Klass, 'Klass', 'Klassier') Now we use the factory to create the instance >>> kl = factory(1, 2, foo=3, bar=4) and make sure that the correct class was used to create the object: >>> kl.__class__ Since we passed in a couple positional and keyword arguments >>> kl.args (1, 2) >>> kl.kw {'foo': 3, 'bar': 4} >>> factory2(3) 3 >>> factory3(3) 3 Title and Description ~~~~~~~~~~~~~~~~~~~~~ >>> factory.title 'Klass' >>> factory.description 'Klassier' >>> factory2.title 'Func' >>> factory2.description 'Function' >>> factory3.title 'Func' >>> factory3.description 'Function' Provided Interfaces ~~~~~~~~~~~~~~~~~~~ >>> implemented = factory.getInterfaces() >>> implemented.isOrExtends(IKlass) True >>> list(implemented) [] >>> implemented2 = factory2.getInterfaces() >>> list(implemented2) [] >>> implemented3 = factory3.getInterfaces() >>> list(implemented3) [] The Component Architecture Factory API -------------------------------------- >>> import zope.component >>> factory = Factory(Klass, 'Klass', 'Klassier') >>> gsm = zope.component.getGlobalSiteManager() >>> from zope.component.interfaces import IFactory >>> gsm.registerUtility(factory, IFactory, 'klass') Creating an Object ~~~~~~~~~~~~~~~~~~ >>> kl = zope.component.createObject('klass', 1, 2, foo=3, bar=4) >>> isinstance(kl, Klass) True >>> kl.args (1, 2) >>> kl.kw {'foo': 3, 'bar': 4} Accessing Provided Interfaces ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ >>> implemented = zope.component.getFactoryInterfaces('klass') >>> implemented.isOrExtends(IKlass) True >>> [iface for iface in implemented] [] List of All Factories ~~~~~~~~~~~~~~~~~~~~~ >>> [(name, fac.__class__) for name, fac in ... zope.component.getFactoriesFor(IKlass)] [(u'klass', )] Component-Management objects ============================ Component-management objects provide a higher-level component-management API over the basic adapter-registration API provided by the zope.interface package. In particular, it provides: - utilities - support for computing adapters, rather than just looking up adapter factories. - management of registration comments The zope.component.registry.Components class provides an implementation of zope.component.interfaces.IComponents that provides these features. >>> from zope.component import registry >>> from zope.component import tests >>> components = registry.Components('comps') As components are registered, events are generated. Let's register an event subscriber, so we can see the events generated: >>> import zope.event >>> def logevent(event): ... print event >>> zope.event.subscribers.append(logevent) Utilities --------- You can register Utilities using registerUtility: >>> components.registerUtility(tests.U1(1)) Registered event: UtilityRegistration(, I1, u'', 1, None, u'') Here we didn't specify an interface or name. An unnamed utility was registered for interface I1, since that is only interface implemented by the U1 class: >>> components.getUtility(tests.I1) U1(1) You can also register a utility using a factory instead of a utility instance: >>> def factory(): ... return tests.U1(1) >>> components.registerUtility(factory=factory) Unregistered event: UtilityRegistration(, I1, u'', 1, None, u'') Registered event: UtilityRegistration(, I1, u'', 1, >, u'') If a component implements other than one interface or no interface, then an error will be raised: >>> components.registerUtility(tests.U12(2)) ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... TypeError: The utility doesn't provide a single interface and no provided interface was specified. >>> components.registerUtility(tests.A) ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... TypeError: The utility doesn't provide a single interface and no provided interface was specified. We can provide an interface if desired: >>> components.registerUtility(tests.U12(2), tests.I2) Registered event: UtilityRegistration(, I2, u'', 2, None, u'') and we can specify a name: >>> components.registerUtility(tests.U12(3), tests.I2, u'three') Registered event: UtilityRegistration(, I2, u'three', 3, None, u'') >>> components.getUtility(tests.I2) U12(2) >>> components.getUtility(tests.I2, 'three') U12(3) If you try to get a utility that doesn't exist, you'll get a component lookup error: >>> components.getUtility(tests.I3) ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: (, u'') Unless you use queryUtility: >>> components.queryUtility(tests.I3) >>> components.queryUtility(tests.I3, default=42) 42 You can get information about registered utilities with the registeredUtilities method: >>> for registration in sorted(components.registeredUtilities()): ... print registration.provided, registration.name ... print registration.component, registration.info U1(1) U12(2) three U12(3) Duplicate registrations replace existing ones: >>> components.registerUtility(tests.U1(4), info=u'use 4 now') Unregistered event: UtilityRegistration(, I1, u'', 1, >, u'') Registered event: UtilityRegistration(, I1, u'', 4, None, u'use 4 now') >>> components.getUtility(tests.I1) U1(4) >>> for registration in sorted(components.registeredUtilities()): ... print registration.provided, registration.name ... print registration.component, registration.info U1(4) use 4 now U12(2) three U12(3) As shown in the this example, you can provide an "info" argumemnt when registering utilities. This provides extra documentation about the registration itself that is shown when listing registrations. You can also unregister utilities: >>> components.unregisterUtility(provided=tests.I1) Unregistered event: UtilityRegistration(, I1, u'', 4, None, u'use 4 now') True A boolean is returned indicating whether anything changed: >>> components.queryUtility(tests.I1) >>> for registration in sorted(components.registeredUtilities()): ... print registration.provided, registration.name ... print registration.component, registration.info U12(2) three U12(3) When you unregister, you can specify a component. If the component doesn't match the one registered, then nothing happens: >>> u5 = tests.U1(5) >>> components.registerUtility(u5) Registered event: UtilityRegistration(, I1, u'', 5, None, u'') >>> components.unregisterUtility(tests.U1(6)) False >>> components.queryUtility(tests.I1) U1(5) >>> components.unregisterUtility(u5) Unregistered event: UtilityRegistration(, I1, u'', 5, None, u'') True >>> components.queryUtility(tests.I1) You can get the name and utility for all of the utilities that provide an interface using getUtilitiesFor: >>> sorted(components.getUtilitiesFor(tests.I2)) [(u'', U12(2)), (u'three', U12(3))] getAllUtilitiesRegisteredFor is similar to getUtilitiesFor except that it includes utilities that are overridden. For example, we'll register a utility that for an extending interface of I2: >>> util = tests.U('ext') >>> components.registerUtility(util, tests.I2e) Registered event: UtilityRegistration(, I2e, u'', ext, None, u'') We don't get the new utility for getUtilitiesFor: >>> sorted(components.getUtilitiesFor(tests.I2)) [(u'', U12(2)), (u'three', U12(3))] but we do get it from getAllUtilitiesRegisteredFor: >>> sorted(map(str, components.getAllUtilitiesRegisteredFor(tests.I2))) ['U(ext)', 'U12(2)', 'U12(3)'] Removing a utility also makes it disappear from getUtilitiesFor: >>> components.unregisterUtility(util, tests.I2e) Unregistered event: UtilityRegistration(, I2e, u'', ext, None, u'') True >>> list(components.getAllUtilitiesRegisteredFor(tests.I2e)) [] Adapters -------- You can register adapters with registerAdapter: >>> components.registerAdapter(tests.A12_1) Registered event: AdapterRegistration(, [I1, I2], IA1, u'', A12_1, u'') Here, we didn't specify required interfaces, a provided interface, or a name. The required interfaces were determined from the factory s __component_adapts__ attribute and the provided interface was determined by introspecting what the factory implements. >>> components.getMultiAdapter((tests.U1(6), tests.U12(7)), tests.IA1) A12_1(U1(6), U12(7)) If a factory implements more than one interface, an exception will be raised: >>> components.registerAdapter(tests.A1_12) ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ...

From a usage point of view, there shouldn't be any new behavior beyond what's described in registry.txt. The Zope 3 Component Architecture (Socket Example) ================================================== The component architecture provides an application framework that provides its functionality through loosely-connected components. A *component* can be any Python object and has a particular purpose associated with it. Thus, in a component-based applications you have many small component in contrast to classical object-oriented development, where you have a few big objects. Components communicate via specific APIs, which are formally defined by interfaces, which are provided by the `zope.interface` package. *Interfaces* describe the methods and properties that a component is expected to provide. They are also used as a primary mean to provide developer-level documentation for the components. For more details about interfaces see `zope/interface/README.txt`. The two main types of components are *adapters* and *utilities*. They will be discussed in detail later in this document. Both component types are managed by the *site manager*, with which you can register and access these components. However, most of the site manager's functionality is hidden behind the component architecture's public API, which is documented in `IComponentArchitecture`. Adapters -------- Adapters are a well-established pattern. An *adapter* uses an object providing one interface to produce an object that provides another interface. Here an example: Imagine that you purchased an electric shaver in the US, and thus you require the US socket type. You are now traveling in Germany, where another socket style is used. You will need a device, an adapter, that converts from the German to the US socket style. The functionality of adapters is actually natively provided by the `zope.interface` package and is thus well documented there. The `human.txt` file provides a gentle introduction to adapters, whereby `adapter.txt` is aimed at providing a comprehensive insight into adapters, but is too abstract for many as an initial read. Thus, we will only explain adapters in the context of the component architecture's API. So let's say that we have a German socket >>> from zope.interface import Interface, implements >>> class IGermanSocket(Interface): ... pass >>> class Socket(object): ... def __repr__(self): ... return '' %self.__class__.__name__ >>> class GermanSocket(Socket): ... """German wall socket.""" ... implements(IGermanSocket) and we want to convert it to an US socket >>> class IUSSocket(Interface): ... pass so that our shaver can be used in Germany. So we go to a German electronics store to look for an adapter that we can plug in the wall: >>> class GermanToUSSocketAdapter(Socket): ... implements(IUSSocket) ... __used_for__ = IGermanSocket ... ... def __init__(self, socket): ... self.context = socket Note that I could have called the passed in socket any way I like, but `context` is the standard name accepted. Single Adapters ~~~~~~~~~~~~~~~ Before we can use the adapter, we have to buy it and make it part of our inventory. In the component architecture we do this by registering the adapter with the framework, more specifically with the global site manager: >>> import zope.component >>> gsm = zope.component.getGlobalSiteManager() >>> gsm.registerAdapter(GermanToUSSocketAdapter, (IGermanSocket,), IUSSocket) `zope.component` is the component architecture API that is being presented by this file. You registered an adapter from `IGermanSocket` to `IUSSocket` having no name (thus the empty string). Anyways, you finally get back to your hotel room and shave, since you have not been able to shave in the plane. In the bathroom you discover a socket: >>> bathroomDE = GermanSocket() >>> IGermanSocket.providedBy(bathroomDE) True You now insert the adapter in the German socket >>> bathroomUS = zope.component.getAdapter(bathroomDE, IUSSocket, '') so that the socket now provides the US version: >>> IUSSocket.providedBy(bathroomUS) True Now you can insert your shaver and get on with your day. After a week you travel for a couple of days to the Prague and you notice that the Czech have yet another socket type: >>> class ICzechSocket(Interface): ... pass >>> class CzechSocket(Socket): ... implements(ICzechSocket) >>> czech = CzechSocket() You try to find an adapter for your shaver in your bag, but you fail, since you do not have one: >>> zope.component.getAdapter(czech, IUSSocket, '') \ ... #doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: (, , '') or the more graceful way: >>> marker = object() >>> socket = zope.component.queryAdapter(czech, IUSSocket, '', marker) >>> socket is marker True In the component architecture API any `get*` method will fail with a specific exception, if a query failed, whereby methods starting with `query*` will always return a `default` value after a failure. Named Adapters ~~~~~~~~~~~~~~ You are finally back in Germany. You also brought your DVD player and a couple DVDs with you, which you would like to watch. Your shaver was able to convert automatically from 110 volts to 240 volts, but your DVD player cannot. So you have to buy another adapter that also handles converting the voltage and the frequency of the AC current: >>> class GermanToUSSocketAdapterAndTransformer(object): ... implements(IUSSocket) ... __used_for__ = IGermanSocket ... ... def __init__(self, socket): ... self.context = socket Now, we need a way to keep the two adapters apart. Thus we register them with a name: >>> gsm.registerAdapter(GermanToUSSocketAdapter, ... (IGermanSocket,), IUSSocket, 'shaver',) >>> gsm.registerAdapter(GermanToUSSocketAdapterAndTransformer, ... (IGermanSocket,), IUSSocket, 'dvd') Now we simply look up the adapters using their labels (called *name*): >>> socket = zope.component.getAdapter(bathroomDE, IUSSocket, 'shaver') >>> socket.__class__ is GermanToUSSocketAdapter True >>> socket = zope.component.getAdapter(bathroomDE, IUSSocket, 'dvd') >>> socket.__class__ is GermanToUSSocketAdapterAndTransformer True Clearly, we do not have an adapter for the MP3 player >>> zope.component.getAdapter(bathroomDE, IUSSocket, 'mp3') \ ... #doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: (, , 'mp3') but you could use the 'dvd' adapter in this case of course. ;) Sometimes you want to know all adapters that are available. Let's say you want to know about all the adapters that convert a German to a US socket type: >>> sockets = list(zope.component.getAdapters((bathroomDE,), IUSSocket)) >>> len(sockets) 3 >>> names = [name for name, socket in sockets] >>> names.sort() >>> names [u'', u'dvd', u'shaver'] `zope.component.getAdapters()` returns a list of tuples. The first entry of the tuple is the name of the adapter and the second is the adapter itself. Multi-Adapters ~~~~~~~~~~~~~~ After watching all the DVDs you brought at least twice, you get tired of them and you want to listen to some music using your MP3 player. But darn, the MP3 player plug has a ground pin and all the adapters you have do not support that: >>> class IUSGroundedSocket(IUSSocket): ... pass So you go out another time to buy an adapter. This time, however, you do not buy yet another adapter, but a piece that provides the grounding plug: >>> class IGrounder(Interface): ... pass >>> class Grounder(object): ... implements(IGrounder) ... def __repr__(self): ... return '' Then together they will provided a grounded us socket: >>> class GroundedGermanToUSSocketAdapter(object): ... implements(IUSGroundedSocket) ... __used_for__ = (IGermanSocket, IGrounder) ... def __init__(self, socket, grounder): ... self.socket, self.grounder = socket, grounder You now register the combination, so that you know you can create a `IUSGroundedSocket`: >>> gsm.registerAdapter(GroundedGermanToUSSocketAdapter, ... (IGermanSocket, IGrounder), IUSGroundedSocket, 'mp3') Given the grounder >>> grounder = Grounder() and a German socket >>> livingroom = GermanSocket() we can now get a grounded US socket: >>> socket = zope.component.getMultiAdapter((livingroom, grounder), ... IUSGroundedSocket, 'mp3') >>> socket.__class__ is GroundedGermanToUSSocketAdapter True >>> socket.socket is livingroom True >>> socket.grounder is grounder True Of course, you do not have a 'dvd' grounded US socket available: >>> zope.component.getMultiAdapter((livingroom, grounder), ... IUSGroundedSocket, 'dvd') \ ... #doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: ((, ), , 'dvd') >>> socket = zope.component.queryMultiAdapter( ... (livingroom, grounder), IUSGroundedSocket, 'dvd', marker) >>> socket is marker True Again, you might want to read `adapter.txt` in `zope.interface` for a more comprehensive coverage of multi-adapters. Subscribers ----------- While subscribers are directly supported by the adapter registry and are adapters for all theoretical purposes, practically it might be better to think of them as separate components. Subscribers are particularly useful for events. Let's say one of our adapters overheated and caused a small fire: >>> class IFire(Interface): ... pass >>> class Fire(object): ... implements(IFire) >>> fire = Fire() We want to use all available objects to put out the fire: >>> class IFireExtinguisher(Interface): ... def extinguish(): ... pass >>> class FireExtinguisher(object): ... def __init__(self, fire): ... pass ... def extinguish(self): ... "Place extinguish code here." ... print 'Used ' + self.__class__.__name__ + '.' Here some specific methods to put out the fire: >>> class PowderExtinguisher(FireExtinguisher): ... pass >>> gsm.registerSubscriptionAdapter(PowderExtinguisher, ... (IFire,), IFireExtinguisher) >>> class Blanket(FireExtinguisher): ... pass >>> gsm.registerSubscriptionAdapter(Blanket, (IFire,), IFireExtinguisher) >>> class SprinklerSystem(FireExtinguisher): ... pass >>> gsm.registerSubscriptionAdapter(SprinklerSystem, ... (IFire,), IFireExtinguisher) Now let use all these things to put out the fire: >>> extinguishers = zope.component.subscribers((fire,), IFireExtinguisher) >>> extinguishers.sort() >>> for extinguisher in extinguishers: ... extinguisher.extinguish() Used Blanket. Used PowderExtinguisher. Used SprinklerSystem. If no subscribers are found for a particular object, then an empty list is returned: >>> zope.component.subscribers((object(),), IFireExtinguisher) [] Utilities --------- Utilities are the second type of component, the component architecture implements. *Utilities* are simply components that provide an interface. When you register an utility, you always register an instance (in contrast to a factory for adapters) since the initialization and setup process of a utility might be complex and is not well defined. In some ways a utility is much more fundamental than an adapter, because an adapter cannot be used without another component, but a utility is always self-contained. I like to think of utilities as the foundation of your application and adapters as components extending beyond this foundation. Back to our story... After your vacation is over you fly back home to Tampa, Florida. But it is August now, the middle of the Hurricane season. And, believe it or not, you are worried that you will not be able to shave when the power goes out for several days. (You just hate wet shavers.) So you decide to go to your favorite hardware store and by a Diesel-powered electric generator. The generator provides of course a US-style socket: >>> class Generator(object): ... implements(IUSSocket) ... def __repr__(self): ... return '' >>> generator = Generator() Like for adapters, we now have to add the newly-acquired generator to our inventory by registering it as a utility: >>> gsm.registerUtility(generator, IUSSocket) We can now get the utility using >>> utility = zope.component.getUtility(IUSSocket) >>> utility is generator True As you can see, it is very simple to register and retrieve utilities. If a utility does not exist for a particular interface, such as the German socket, then the lookup fails >>> zope.component.getUtility(IGermanSocket) Traceback (most recent call last): ... ComponentLookupError: (, '') or more gracefully when specifying a default value: >>> default = object() >>> utility = zope.component.queryUtility(IGermanSocket, default=default) >>> utility is default True Note: The only difference between `getUtility()` and `queryUtility()` is the fact that you can specify a default value for the latter function, so that it will never cause a `ComponentLookupError`. Named Utilities ~~~~~~~~~~~~~~~ It is often desirable to have several utilities providing the same interface per site. This way you can implement any sort of registry using utilities. For this reason, utilities -- like adapters -- can be named. In the context of our story, we might want to do the following: You really do not trust gas stations either. What if the roads are blocked after a hurricane and the gas stations run out of oil. So you look for another renewable power source. Then you think about solar panels! After a storm there is usually very nice weather, so why not? Via the Web you order a set of 110V/120W solar panels that provide a regular US-style socket as output: >>> class SolarPanel(object): ... implements(IUSSocket) ... def __repr__(self): ... return '' >>> panel = SolarPanel() Once it arrives, we add it to our inventory: >>> gsm.registerUtility(panel, IUSSocket, 'Solar Panel') You can now access the solar panel using >>> utility = zope.component.getUtility(IUSSocket, 'Solar Panel') >>> utility is panel True Of course, if a utility is not available, then the lookup will simply fail >>> zope.component.getUtility(IUSSocket, 'Wind Mill') Traceback (most recent call last): ... ComponentLookupError: (, 'Wind Mill') or more gracefully when specifying a default value: >>> default = object() >>> utility = zope.component.queryUtility(IUSSocket, 'Wind Mill', ... default=default) >>> utility is default True Now you want to look at all the utilities you have for a particular kind. The following API function will return a list of name/utility pairs: >>> utils = list(zope.component.getUtilitiesFor(IUSSocket)) >>> utils.sort() >>> utils #doctest: +NORMALIZE_WHITESPACE [(u'', ), (u'Solar Panel', )] Another method of looking up all utilities is by using `getAllUtilitiesRegisteredFor(iface)`. This function will return an iterable of utilities (without names); however, it will also return overridden utilities. If you are not using multiple site managers, you will not actually need this method. >>> utils = list(zope.component.getAllUtilitiesRegisteredFor(IUSSocket)) >>> utils.sort() >>> utils [, ] Factories ~~~~~~~~~ A *factory* is a special kind of utility that exists to create other components. A factory is always identified by a name. It also provides a title and description and is able to tell the developer what interfaces the created object will provide. The advantage of using a factory to create an object instead of directly instantiating a class or executing any other callable is that we can refer to the factory by name. As long as the name stays fixed, the implementation of the callable can be renamed or moved without a breakage in code. Let's say that our solar panel comes in parts and they have to be assembled. This assembly would be done by a factory, so let's create one for the solar panel. To do this, we can use a standard implementation of the `IFactory` interface: >>> from zope.component.factory import Factory >>> factory = Factory(SolarPanel, ... 'Solar Panel', ... 'This factory creates a solar panel.') Optionally, I could have also specified the interfaces that the created object will provide, but the factory class is smart enough to determine the implemented interface from the class. We now register the factory: >>> from zope.component.interfaces import IFactory >>> gsm.registerUtility(factory, IFactory, 'SolarPanel') We can now get a list of interfaces the produced object will provide: >>> ifaces = zope.component.getFactoryInterfaces('SolarPanel') >>> IUSSocket in ifaces True By the way, this is equivalent to >>> ifaces2 = factory.getInterfaces() >>> ifaces is ifaces2 True Of course you can also just create an object: >>> panel = zope.component.createObject('SolarPanel') >>> panel.__class__ is SolarPanel True Note: Ignore the first argument (`None`) for now; it is the context of the utility lookup, which is usually an optional argument, but cannot be in this case, since all other arguments beside the `name` are passed in as arguments to the specified callable. Once you register several factories >>> gsm.registerUtility(Factory(Generator), IFactory, 'Generator') you can also determine, which available factories will create objects providing a certain interface: >>> factories = zope.component.getFactoriesFor(IUSSocket) >>> factories = [(name, factory.__class__) for name, factory in factories] >>> factories.sort() >>> factories #doctest: +NORMALIZE_WHITESPACE [(u'Generator', ), (u'SolarPanel', )] Site Managers ------------- Why do we need site managers? Why is the component architecture API not sufficient? Some applications, including Zope 3, have a concept of locations. It is often desirable to have different configurations for these location; this can be done by overwriting existing or adding new component registrations. Site managers in locations below the root location, should be able to delegate requests to their parent locations. The root site manager is commonly known as *global site manager*, since it is always available. You can always get the global site manager using the API: >>> gsm = zope.component.getGlobalSiteManager() >>> from zope.component import globalSiteManager >>> gsm is globalSiteManager True >>> from zope.component.interfaces import IComponentLookup >>> IComponentLookup.providedBy(gsm) True >>> from zope.component.interfaces import IComponents >>> IComponents.providedBy(gsm) True You can also lookup at site manager in a given context. The only requirement is that the context can be adapted to a site manager. So let's create a special site manager: >>> from zope.component.globalregistry import BaseGlobalComponents >>> sm = BaseGlobalComponents() Now we create a context that adapts to the site manager via the `__conform__` method as specified in PEP 246. >>> class Context(object): ... def __init__(self, sm): ... self.sm = sm ... def __conform__(self, interface): ... if interface.isOrExtends(IComponentLookup): ... return self.sm We now instantiate the `Context` with our special site manager: >>> context = Context(sm) >>> context.sm is sm True We can now ask for the site manager of this context: >>> lsm = zope.component.getSiteManager(context) >>> lsm is sm True The site manager instance `lsm` is formally known as a *local site manager* of `context`. CHANGES ******* 3.9.5 (2010-07-09) ================== - Fix test requirements specification. 3.9.4 (2010-04-30) ================== - Prefer the standard libraries doctest module to the one from zope.testing. 3.9.3 (2010-03-08) ================== - The ZCML directives provided by zope.component now register the components in the registry returned by getSiteManager instead of the global registry. This allows the hooking of the getSiteManager method before the load of a ZCML file to register the components in a custom registry. 3.9.2 (2010-01-22) ================== - Fixed a bug introduced by recent refactoring, where passing CheckerPublic to securityAdapterFactory wrongly wrapped the factory into a LocatingUntrustedAdapterFactory. 3.9.1 (2010-01-21) ================== - The tested testrunner somehow gets influenced by options of the outer testrunner, such a the -v option. We modified the tests so that it avoids this. 3.9.0 (2010-01-21) ================== - Add testlayer support. It is now possible to load a ZCML file within tests more easily. See zope.component.testlayer.py and zope.component.testlayer.txt. 3.8.0 (2009-11-16) ================== - Removed the dependencies on zope.proxy and zope.security from the zcml extra: zope.component does not hard depend on them anymore; the support for security proxied components ZCML registrations is enabled only if zope.security and zope.proxy are available. - Moved the IPossibleSite and ISite interfaces here from zope.location as they are dealing with zope.component's concept of a site, but not with location. - Moved the zope.site.hooks functionality to zope.component.hooks as it isn't actually dealing with zope.site's concept of a site. 3.7.1 (2009-07-24) ================== - Fixed a problem, where ``queryNextUtility`` could fail if the context could not be adapted to a ``IComponentLookup``. - Fixed 2 related bugs: When a utility is registered and there was previously a utility registered for the same interface and name, then the old utility is unregistered. The 2 bugs related to this: - There was no ``Unregistered`` for the implicit unregistration. Now there is. - The old utility was still held and returned by getAllUtilitiesRegisteredFor. In other words, it was still considered registered, eeven though it wasn't. A particularly negative consequence of this is that the utility is held in memory or in the database even though it isn't used. 3.7.0 (2009-05-21) ================== - The HookableTests were not run by the testrunner. - Add in zope:view and zope:resource implementations into zope.component.zcml (dependency loaded with zope.component [zcml]). 3.6.0 (2009-03-12) ================== - IMPORTANT: the interfaces that were defined in the zope.component.bbb.interfaces and deprecated for years are now (re)moved. However, some packages, including part of zope framework were still using those interfaces. They will be adapted for this change. If you were using some of those interfaces, you need to adapt your code as well: - The IView and IDefaultViewName were moved to zope.publisher.interfaces. - The IResource was moved to zope.app.publisher.interfaces. - IContextDependent, IPresentation, IPresentationRequest, IResourceFactory, IViewFactory were removed completely. If you used IViewFactory in context of zope.app.form, there's now IWidgetFactory in the zope.app.form.interfaces instead. - Add getNextUtility/queryNextUtility functions that used to be in zope.site earlier (and in zope.app.component even more earlier). - Added a pure-Python 'hookable' implementation, for use when 'zope.hookable' is not present. - Removed use of 'zope.deferredimport' by breaking import cycles. - Cleanup package documentation and changelog a bit. Add sphinx-based documentation building command to the buildout. - Remove deprecated code. - Change package's mailing list address to zope-dev at zope.org, because zope3-dev at zope.org is now retired. 3.5.1 (2008-07-25) ================== - Fix bug introduced in 3.5.0: no longer supported interfaces declared in Python and always wanted an explicit provides="..." attribute. https://bugs.launchpad.net/zope3/+bug/251865 3.5.0 (2008-07-25) ================== - Support registration of utilities via factories through the component registry and return factory information in the registration information. This fixes https://bugs.launchpad.net/zope3/+bug/240631 - Optimized un/registerUtility via storing an optimized data structure for efficient retrieval of already registered utilities. This avoids looping over all utilities when registering a new one. 3.4.0 (2007-09-29) ================== No further changes since 3.4.0a1. 3.4.0a1 (2007-04-22) ==================== Corresponds to zope.component from Zope 3.4.0a1. - In the Zope 3.3.x series, ``zope.component`` was simplified yet once more. See http://wiki.zope.org/zope3/LocalComponentManagementSimplification for the proposal describing the changes. 3.2.0.2 (2006-04-15) ==================== - Fix packaging bug: 'package_dir' must be a *relative* path. 3.2.0.1 (2006-04-14) ==================== - Packaging change: suppress inclusion of 'setup.cfg' in 'sdist' builds. 3.2.0 (2006-01-05) ================== Corresponds to the verison of the zope.component package shipped as part of the Zope 3.2.0 release. - Deprecated services and related APIs. The adapter and utility registries are now available directly via the site manager's 'adapters' and 'utilities' attributes, respectively. Services are accessible, but deprecated, and will be removed in Zope 3.3. - Deprectaed all presentation-related APIs, including all view-related API functions. Use the adapter API functions instead. See http://dev.zope.org/Zope3/ImplementViewsAsAdapters` - Deprecated 'contextdependent' package: site managers are now looked up via a thread global, set during URL traversal. The 'context' argument is now always optional, and should no longer be passed. 3.0.0 (2004-11-07) ================== Corresponds to the verison of the zope.component package shipped as part of the Zope X3.0.0 release.

See zope.component.testlayer.py and zope.component.testlayer.txt. 3.8.0 (2009-11-16) ================== - Removed the dependencies on zope.proxy and zope.security from the zcml extra: zope.component does not hard depend on them anymore; the support for security proxied components ZCML registrations is enabled only if zope.security and zope.proxy are available. - Moved the IPossibleSite and ISite interfaces here from zope.location as they are dealing with zope.component's concept of a site, but not with location. - Moved the zope.site.hooks functionality to zope.component.hooks as it isn't actually dealing with zope.site's concept of a site. 3.7.1 (2009-07-24) ================== - Fixed a problem, where ``queryNextUtility`` could fail if the context could not be adapted to a ``IComponentLookup``. - Fixed 2 related bugs: When a utility is registered and there was previously a utility registered for the same interface and name, then the old utility is unregistered. The 2 bugs related to this: - There was no ``Unregistered`` for the implicit unregistration. Now there is. - The old utility was still held and returned by getAllUtilitiesRegisteredFor. In other words, it was still considered registered, eeven though it wasn't. A particularly negative consequence of this is that the utility is held in memory or in the database even though it isn't used. 3.7.0 (2009-05-21) ================== - The HookableTests were not run by the testrunner. - Add in zope:view and zope:resource implementations into zope.component.zcml (dependency loaded with zope.component [zcml]). 3.6.0 (2009-03-12) ================== - IMPORTANT: the interfaces that were defined in the zope.component.bbb.interfaces and deprecated for years are now (re)moved. However, some packages, including part of zope framework were still using those interfaces. They will be adapted for this change. If you were using some of those interfaces, you need to adapt your code as well: - The IView and IDefaultViewName were moved to zope.publisher.interfaces. - The IResource was moved to zope.app.publisher.interfaces. - IContextDependent, IPresentation, IPresentationRequest, IResourceFactory, IViewFactory were removed completely. If you used IViewFactory in context of zope.app.form, there's now IWidgetFactory in the zope.app.form.interfaces instead. - Add getNextUtility/queryNextUtility functions that used to be in zope.site earlier (and in zope.app.component even more earlier). - Added a pure-Python 'hookable' implementation, for use when 'zope.hookable' is not present. - Removed use of 'zope.deferredimport' by breaking import cycles. - Cleanup package documentation and changelog a bit. Add sphinx-based documentation building command to the buildout. - Remove deprecated code. - Change package's mailing list address to zope-dev at zope.org, because zope3-dev at zope.org is now retired. 3.5.1 (2008-07-25) ================== - Fix bug introduced in 3.5.0: no longer supported interfaces declared in Python and always wanted an explicit provides="..." attribute. https://bugs.launchpad.net/zope3/+bug/251865 3.5.0 (2008-07-25) ================== - Support registration of utilities via factories through the component registry and return factory information in the registration information. This fixes https://bugs.launchpad.net/zope3/+bug/240631 - Optimized un/registerUtility via storing an optimized data structure for efficient retrieval of already registered utilities. This avoids looping over all utilities when registering a new one. 3.4.0 (2007-09-29) ================== No further changes since 3.4.0a1. 3.4.0a1 (2007-04-22) ==================== Corresponds to zope.component from Zope 3.4.0a1. - In the Zope 3.3.x series, ``zope.component`` was simplified yet once more. See http://wiki.zope.org/zope3/LocalComponentManagementSimplification for the proposal describing the changes. 3.2.0.2 (2006-04-15) ==================== - Fix packaging bug: 'package_dir' must be a *relative* path. 3.2.0.1 (2006-04-14) ==================== - Packaging change: suppress inclusion of 'setup.cfg' in 'sdist' builds. 3.2.0 (2006-01-05) ================== Corresponds to the verison of the zope.component package shipped as part of the Zope 3.2.0 release. - Deprecated services and related APIs. The adapter and utility registries are now available directly via the site manager's 'adapters' and 'utilities' attributes, respectively. Services are accessible, but deprecated, and will be removed in Zope 3.3. - Deprectaed all presentation-related APIs, including all view-related API functions. Use the adapter API functions instead. See http://dev.zope.org/Zope3/ImplementViewsAsAdapters` - Deprecated 'contextdependent' package: site managers are now looked up via a thread global, set during URL traversal. The 'context' argument is now always optional, and should no longer be passed. 3.0.0 (2004-11-07) ================== Corresponds to the verison of the zope.component package shipped as part of the Zope X3.0.0 release. zope2.13-2.13.21/source/zope.component/src/0000755000175000017500000000000012214017426017203 5ustar arnauarnauzope2.13-2.13.21/source/zope.component/src/zope/0000755000175000017500000000000012214017426020160 5ustar arnauarnauzope2.13-2.13.21/source/zope.component/src/zope/component/0000755000175000017500000000000012214017426022162 5ustar arnauarnauzope2.13-2.13.21/source/zope.component/src/zope/component/registry.txt0000644000175000017500000011570612214017426024605 0ustar arnauarnauComponent-Management objects ============================ Component-management objects provide a higher-level component-management API over the basic adapter-registration API provided by the zope.interface package. In particular, it provides: - utilities - support for computing adapters, rather than just looking up adapter factories. - management of registration comments The zope.component.registry.Components class provides an implementation of zope.component.interfaces.IComponents that provides these features. >>> from zope.component import registry >>> from zope.component import tests >>> components = registry.Components('comps') As components are registered, events are generated. Let's register an event subscriber, so we can see the events generated: >>> import zope.event >>> def logevent(event): ... print event >>> zope.event.subscribers.append(logevent) Utilities --------- You can register Utilities using registerUtility: >>> components.registerUtility(tests.U1(1)) Registered event: UtilityRegistration(, I1, u'', 1, None, u'') Here we didn't specify an interface or name. An unnamed utility was registered for interface I1, since that is only interface implemented by the U1 class: >>> components.getUtility(tests.I1) U1(1) You can also register a utility using a factory instead of a utility instance: >>> def factory(): ... return tests.U1(1) >>> components.registerUtility(factory=factory) Unregistered event: UtilityRegistration(, I1, u'', 1, None, u'') Registered event: UtilityRegistration(, I1, u'', 1, >, u'') If a component implements other than one interface or no interface, then an error will be raised: >>> components.registerUtility(tests.U12(2)) ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ...

TypeError: The utility doesn't provide a single interface and no provided interface was specified. We can provide an interface if desired: >>> components.registerUtility(tests.U12(2), tests.I2) Registered event: UtilityRegistration(, I2, u'', 2, None, u'') and we can specify a name: >>> components.registerUtility(tests.U12(3), tests.I2, u'three') Registered event: UtilityRegistration(, I2, u'three', 3, None, u'') >>> components.getUtility(tests.I2) U12(2) >>> components.getUtility(tests.I2, 'three') U12(3) If you try to get a utility that doesn't exist, you'll get a component lookup error: >>> components.getUtility(tests.I3) ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: (, u'') Unless you use queryUtility: >>> components.queryUtility(tests.I3) >>> components.queryUtility(tests.I3, default=42) 42 You can get information about registered utilities with the registeredUtilities method: >>> for registration in sorted(components.registeredUtilities()): ... print registration.provided, registration.name ... print registration.component, registration.info U1(1) U12(2) three U12(3) Duplicate registrations replace existing ones: >>> components.registerUtility(tests.U1(4), info=u'use 4 now') Unregistered event: UtilityRegistration(, I1, u'', 1, >, u'') Registered event: UtilityRegistration(, I1, u'', 4, None, u'use 4 now') >>> components.getUtility(tests.I1) U1(4) >>> for registration in sorted(components.registeredUtilities()): ... print registration.provided, registration.name ... print registration.component, registration.info U1(4) use 4 now U12(2) three U12(3) As shown in the this example, you can provide an "info" argumemnt when registering utilities. This provides extra documentation about the registration itself that is shown when listing registrations. You can also unregister utilities: >>> components.unregisterUtility(provided=tests.I1) Unregistered event: UtilityRegistration(, I1, u'', 4, None, u'use 4 now') True A boolean is returned indicating whether anything changed: >>> components.queryUtility(tests.I1) >>> for registration in sorted(components.registeredUtilities()): ... print registration.provided, registration.name ... print registration.component, registration.info U12(2) three U12(3) When you unregister, you can specify a component. If the component doesn't match the one registered, then nothing happens: >>> u5 = tests.U1(5) >>> components.registerUtility(u5) Registered event: UtilityRegistration(, I1, u'', 5, None, u'') >>> components.unregisterUtility(tests.U1(6)) False >>> components.queryUtility(tests.I1) U1(5) >>> components.unregisterUtility(u5) Unregistered event: UtilityRegistration(, I1, u'', 5, None, u'') True >>> components.queryUtility(tests.I1) You can get the name and utility for all of the utilities that provide an interface using getUtilitiesFor: >>> sorted(components.getUtilitiesFor(tests.I2)) [(u'', U12(2)), (u'three', U12(3))] getAllUtilitiesRegisteredFor is similar to getUtilitiesFor except that it includes utilities that are overridden. For example, we'll register a utility that for an extending interface of I2: >>> util = tests.U('ext') >>> components.registerUtility(util, tests.I2e) Registered event: UtilityRegistration(, I2e, u'', ext, None, u'') We don't get the new utility for getUtilitiesFor: >>> sorted(components.getUtilitiesFor(tests.I2)) [(u'', U12(2)), (u'three', U12(3))] but we do get it from getAllUtilitiesRegisteredFor: >>> sorted(map(str, components.getAllUtilitiesRegisteredFor(tests.I2))) ['U(ext)', 'U12(2)', 'U12(3)'] Removing a utility also makes it disappear from getUtilitiesFor: >>> components.unregisterUtility(util, tests.I2e) Unregistered event: UtilityRegistration(, I2e, u'', ext, None, u'') True >>> list(components.getAllUtilitiesRegisteredFor(tests.I2e)) [] Adapters -------- You can register adapters with registerAdapter: >>> components.registerAdapter(tests.A12_1) Registered event: AdapterRegistration(, [I1, I2], IA1, u'', A12_1, u'') Here, we didn't specify required interfaces, a provided interface, or a name. The required interfaces were determined from the factory s __component_adapts__ attribute and the provided interface was determined by introspecting what the factory implements. >>> components.getMultiAdapter((tests.U1(6), tests.U12(7)), tests.IA1) A12_1(U1(6), U12(7)) If a factory implements more than one interface, an exception will be raised: >>> components.registerAdapter(tests.A1_12) ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ...

This can be seen in the second double-dispatch output, where the first argument is the object being registered, which is dispatchHandlerRegistrationEvent.

ConfigurationError: security proxied components are not supported because zope.security is not available Components may be registered using the registration API exposed by ``zope.component`` (provideAdapter, provideUtility, etc.). They may also be registered using configuration files. The common way to do that is by using ZCML (Zope Configuration Markup Language), an XML spelling of component registration. In ZCML, each XML element is a *directive*. There are different top-level directives that let us register components. We will introduce them one by one here. This helper will let us easily execute ZCML snippets: >>> from cStringIO import StringIO >>> from zope.configuration.xmlconfig import xmlconfig >>> def runSnippet(snippet): ... template = """\ ... ... %s ... """ ... xmlconfig(StringIO(template % snippet)) adapter ------- Adapters play a key role in the Component Architecture. In ZCML, they are registered with the directive. >>> from zope.component.testfiles.adapter import A1, A2, A3, Handler >>> from zope.component.testfiles.adapter import I1, I2, I3, IS >>> from zope.component.testfiles.components import IContent, Content, Comp, comp Before we register the first test adapter, we can verify that adapter lookup doesn't work yet: >>> from zope.component.tests import clearZCML >>> clearZCML() >>> from zope.component.testfiles.components import IApp >>> IApp(Content(), None) is None True Then we register the adapter and see that the lookup works: >>> runSnippet(''' ... ''') >>> IApp(Content()).__class__ It is also possible to give adapters names. Then the combination of required interface, provided interface and name makes the adapter lookup unique. The name is supplied using the ``name`` argument to the directive: >>> from zope.component.tests import clearZCML >>> clearZCML() >>> import zope.component >>> zope.component.queryAdapter(Content(), IApp, 'test') is None True >>> runSnippet(''' ... ''') >>> zope.component.getAdapter(Content(), IApp, 'test').__class__ Adapter factories ~~~~~~~~~~~~~~~~~ It is possible to supply more than one adapter factory. In this case, during adapter lookup each factory will be called and the return value will be given to the next factory. The return value of the last factory is returned as the result of the adapter lookup. For examle: >>> clearZCML() >>> runSnippet(''' ... ''') The resulting adapter is an A3, around an A2, around an A1, around the adapted object: >>> content = Content() >>> a3 = IApp(content) >>> a3.__class__ is A3 True >>> a2 = a3.context[0] >>> a2.__class__ is A2 True >>> a1 = a2.context[0] >>> a1.__class__ is A1 True >>> a1.context[0] is content True Of course, if no factory is provided at all, we will get an error: >>> runSnippet(''' ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 4.2-8.8 ValueError: No factory specified Declaring ``for`` and ``provides`` in Python ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The directive can figure out from the in-line Python declaration (using ``zope.component.adapts()`` or ``zope.component.adapter()`` as well as ``zope.interface.implements``) what the adapter should be registered for and what it provides:: >>> clearZCML() >>> IApp(Content(), None) is None True >>> runSnippet(''' ... ''') >>> IApp(Content()).__class__ Of course, if the adapter has no ``implements()`` declaration, ZCML can't figure out what it provides: >>> runSnippet(''' ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 4.2-7.8 TypeError: Missing 'provides' attribute On the other hand, if the factory implements more than one interface, ZCML can't figure out what it should provide either: >>> runSnippet(''' ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 4.2-7.8 TypeError: Missing 'provides' attribute A not so common edge case is registering adapters directly for classes, not for interfaces. For example: >>> clearZCML() >>> runSnippet(''' ... ''') >>> content = Content() >>> a1 = zope.component.getAdapter(content, I1, '') >>> isinstance(a1, A1) True This time, any object providing ``IContent`` won't work if it's not an instance of the ``Content`` class: >>> import zope.interface >>> class MyContent: ... zope.interface.implements(IContent) >>> zope.component.getAdapter(MyContent(), I1, '') # doctest: +ELLIPSIS Traceback (most recent call last): ... ComponentLookupError: ... Multi-adapters ~~~~~~~~~~~~~~ Conventional adapters adapt one object to provide another interface. Multi-adapters adapt several objects at once: >>> clearZCML() >>> runSnippet(''' ... ''') >>> content = Content() >>> a1 = A1() >>> a2 = A2() >>> a3 = zope.component.queryMultiAdapter((content, a1, a2), I3) >>> a3.__class__ is A3 True >>> a3.context == (content, a1, a2) True You can even adapt an empty list of objects (we call this a null-adapter): >>> clearZCML() >>> runSnippet(''' ... ''') >>> a3 = zope.component.queryMultiAdapter((), I3) >>> a3.__class__ is A3 True >>> a3.context == () True Even with multi-adapters, ZCML can figure out the ``for`` and ``provides`` parameters from the Python declarations: >>> clearZCML() >>> runSnippet(''' ... ''') >>> a3 = zope.component.queryMultiAdapter((content, a1, a2), I3) >>> a3.__class__ is A3 True >>> a3.context == (content, a1, a2) True Chained factories are not supported for multi-adapters, though: >>> clearZCML() >>> runSnippet(''' ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 4.2-11.8 ValueError: Can't use multiple factories and multiple for And neither for null-adapters: >>> clearZCML() >>> runSnippet(''' ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 4.2-9.8 ValueError: Can't use multiple factories and multiple for subscriber ---------- With the directive you can register subscription adapters or event subscribers with the adapter registry. Consider this very typical example of a directive: >>> clearZCML() >>> runSnippet(''' ... ''') >>> content = Content() >>> a1 = A1() >>> subscribers = zope.component.subscribers((content, a1), IS) >>> a3 = subscribers[0] >>> a3.__class__ is A3 True >>> a3.context == (content, a1) True Note how ZCML provides some additional information when registering components, such as the ZCML filename and line numbers: >>> sm = zope.component.getSiteManager() >>> doc = [reg.info for reg in sm.registeredSubscriptionAdapters() ... if reg.provided is IS][0] >>> print doc File "", line 4.2-9.8 Could not read source. The "fun" behind subscription adapters/subscribers is that when several ones are declared for the same for/provides, they are all found. With regular adapters, the most specific one (and in doubt the one registered last) wins. Consider these two subscribers: >>> clearZCML() >>> runSnippet(''' ... ... ''') >>> subscribers = zope.component.subscribers((content, a1), IS) >>> len(subscribers) 2 >>> sorted([a.__class__.__name__ for a in subscribers]) ['A2', 'A3'] Declaring ``for`` and ``provides`` in Python ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Like the directive, the directive can figure out from the in-line Python declaration (using ``zope.component.adapts()`` or ``zope.component.adapter()``) what the subscriber should be registered for: >>> clearZCML() >>> runSnippet(''' ... ''') >>> content = Content() >>> a2 = A2() >>> subscribers = zope.component.subscribers((content, a1, a2), IS) >>> a3 = subscribers[0] >>> a3.__class__ is A3 True >>> a3.context == (content, a1, a2) True In the same way the directive can figure out what a subscriber provides: >>> clearZCML() >>> runSnippet(''' ... ''') >>> sm = zope.component.getSiteManager() >>> a3 = sm.adapters.subscriptions((IContent, I1, I2), None)[0] >>> a3 is A3 True A not so common edge case is declaring subscribers directly for classes, not for interfaces. For example: >>> clearZCML() >>> runSnippet(''' ... ''') >>> subs = list(zope.component.subscribers((Content(),), I1)) >>> isinstance(subs[0], A1) True This time, any object providing ``IContent`` won't work if it's not an instance of the ``Content`` class: >>> list(zope.component.subscribers((MyContent(),), I1)) [] Event subscriber (handlers) ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Sometimes, subscribers don't need to be adapters that actually provide anything. It's enough that a callable is called for a certain event. >>> clearZCML() >>> runSnippet(''' ... ''') In this case, simply getting the subscribers is enough to invoke them: >>> list(zope.component.subscribers((content, a1), None)) [] >>> content.args == ((a1,),) True utility ------- Apart from adapters (and subscription adapters), the Component Architecture knows a second kind of component: utilities. They are registered using the directive. Before we register the first test utility, we can verify that utility lookup doesn't work yet: >>> clearZCML() >>> zope.component.queryUtility(IApp) is None True Then we register the utility: >>> runSnippet(''' ... ''') >>> zope.component.getUtility(IApp) is comp True Like adapters, utilities can also have names. There can be more than one utility registered for a certain interface, as long as they each have a different name. First, we make sure that there's no utility yet: >>> clearZCML() >>> zope.component.queryUtility(IApp, 'test') is None True Then we register it: >>> runSnippet(''' ... ''') >>> zope.component.getUtility(IApp, 'test') is comp True Utilities can also be registered from a factory. In this case, the ZCML handler calls the factory (without any arguments) and registers the returned value as a utility. Typically, you'd pass a class for the factory: >>> clearZCML() >>> zope.component.queryUtility(IApp) is None True >>> runSnippet(''' ... ''') >>> zope.component.getUtility(IApp).__class__ is Comp True Declaring ``provides`` in Python ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Like other directives, can also figure out which interface a utility provides from the Python declaration: >>> clearZCML() >>> zope.component.queryUtility(IApp) is None True >>> runSnippet(''' ...

the registration API exposed by ``zope.component`` (provideAdapter, provideUtility, etc.). They may also be registered using configuration files. The common way to do that is by using ZCML (Zope Configuration Markup Language), an XML spelling of component registration. In ZCML, each XML element is a *directive*. There are different top-level directives that let us register components. We will introduce them one by one here. This helper will let us easily execute ZCML snippets: >>> from cStringIO import StringIO >>> from zope.configuration.xmlconfig import xmlconfig >>> def runSnippet(snippet): ... template = """\ ... ... %s ... """ ... xmlconfig(StringIO(template % snippet)) adapter ------- Adapters play a key role in the Component Architecture. In ZCML, they are registered with the directive. >>> from zope.component.testfiles.adapter import A1, A2, A3, Handler >>> from zope.component.testfiles.adapter import I1, I2, I3, IS >>> from zope.component.testfiles.components import IContent, Content, Comp, comp Before we register the first test adapter, we can verify that adapter lookup doesn't work yet: >>> from zope.component.tests import clearZCML >>> clearZCML() >>> from zope.component.testfiles.components import IApp >>> IApp(Content(), None) is None True Then we register the adapter and see that the lookup works: >>> runSnippet(''' ... ''') >>> IApp(Content()).__class__ It is also possible to give adapters names. Then the combination of required interface, provided interface and name makes the adapter lookup unique. The name is supplied using the ``name`` argument to the directive: >>> from zope.component.tests import clearZCML >>> clearZCML() >>> import zope.component >>> zope.component.queryAdapter(Content(), IApp, 'test') is None True >>> runSnippet(''' ... ''') >>> zope.component.getAdapter(Content(), IApp, 'test').__class__ Adapter factories ~~~~~~~~~~~~~~~~~ It is possible to supply more than one adapter factory. In this case, during adapter lookup each factory will be called and the return value will be given to the next factory. The return value of the last factory is returned as the result of the adapter lookup. For examle: >>> clearZCML() >>> runSnippet(''' ... ''') The resulting adapter is an A3, around an A2, around an A1, around the adapted object: >>> content = Content() >>> a3 = IApp(content) >>> a3.__class__ is A3 True >>> a2 = a3.context[0] >>> a2.__class__ is A2 True >>> a1 = a2.context[0] >>> a1.__class__ is A1 True >>> a1.context[0] is content True Of course, if no factory is provided at all, we will get an error: >>> runSnippet(''' ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 4.2-8.8 ValueError: No factory specified Declaring ``for`` and ``provides`` in Python ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The directive can figure out from the in-line Python declaration (using ``zope.component.adapts()`` or ``zope.component.adapter()`` as well as ``zope.interface.implements``) what the adapter should be registered for and what it provides:: >>> clearZCML() >>> IApp(Content(), None) is None True >>> runSnippet(''' ... ''') >>> IApp(Content()).__class__ Of course, if the adapter has no ``implements()`` declaration, ZCML can't figure out what it provides: >>> runSnippet(''' ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 4.2-7.8 TypeError: Missing 'provides' attribute On the other hand, if the factory implements more than one interface, ZCML can't figure out what it should provide either: >>> runSnippet(''' ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 4.2-7.8 TypeError: Missing 'provides' attribute A not so common edge case is registering adapters directly for classes, not for interfaces. For example: >>> clearZCML() >>> runSnippet(''' ... ''') >>> content = Content() >>> a1 = zope.component.getAdapter(content, I1, '') >>> isinstance(a1, A1) True This time, any object providing ``IContent`` won't work if it's not an instance of the ``Content`` class: >>> import zope.interface >>> class MyContent: ... zope.interface.implements(IContent) >>> zope.component.getAdapter(MyContent(), I1, '') # doctest: +ELLIPSIS Traceback (most recent call last): ... ComponentLookupError: ... Multi-adapters ~~~~~~~~~~~~~~ Conventional adapters adapt one object to provide another interface. Multi-adapters adapt several objects at once: >>> clearZCML() >>> runSnippet(''' ... ''') >>> content = Content() >>> a1 = A1() >>> a2 = A2() >>> a3 = zope.component.queryMultiAdapter((content, a1, a2), I3) >>> a3.__class__ is A3 True >>> a3.context == (content, a1, a2) True You can even adapt an empty list of objects (we call this a null-adapter): >>> clearZCML() >>> runSnippet(''' ... ''') >>> a3 = zope.component.queryMultiAdapter((), I3) >>> a3.__class__ is A3 True >>> a3.context == () True Even with multi-adapters, ZCML can figure out the ``for`` and ``provides`` parameters from the Python declarations: >>> clearZCML() >>> runSnippet(''' ... ''') >>> a3 = zope.component.queryMultiAdapter((content, a1, a2), I3) >>> a3.__class__ is A3 True >>> a3.context == (content, a1, a2) True Chained factories are not supported for multi-adapters, though: >>> clearZCML() >>> runSnippet(''' ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 4.2-11.8 ValueError: Can't use multiple factories and multiple for And neither for null-adapters: >>> clearZCML() >>> runSnippet(''' ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 4.2-9.8 ValueError: Can't use multiple factories and multiple for Protected adapters ~~~~~~~~~~~~~~~~~~ Adapters can be protected with a permission. First we have to define a permission for which we'll have to register the directive: >>> clearZCML() >>> IApp(Content(), None) is None True >>> import zope.security >>> from zope.configuration.xmlconfig import XMLConfig >>> XMLConfig('meta.zcml', zope.security)() >>> runSnippet(''' ... ... ''') We see that the adapter is a location proxy now so that the appropriate permissions can be found from the context: >>> IApp(Content()).__class__ >>> type(IApp(Content())) We can also go about it a different way. Let's make a public adapter and wrap the adapter in a security proxy. That often happens when an adapter is turned over to untrusted code: >>> clearZCML() >>> IApp(Content(), None) is None True >>> runSnippet(''' ... ''') >>> from zope.security.checker import ProxyFactory >>> adapter = ProxyFactory(IApp(Content())) >>> from zope.security.proxy import getTestProxyItems >>> items = [item[0] for item in getTestProxyItems(adapter)] >>> items ['a', 'f'] >>> from zope.security.proxy import removeSecurityProxy >>> removeSecurityProxy(adapter).__class__ is Comp True Of course, this still works when we let the ZCML directive handler figure out ``for`` and ``provides`` from the Python declarations: >>> clearZCML() >>> runSnippet(''' ... ''') >>> adapter = ProxyFactory(IApp(Content())) >>> [item[0] for item in getTestProxyItems(adapter)] ['a', 'f'] >>> removeSecurityProxy(adapter).__class__ is Comp True It also works with multi adapters: >>> clearZCML() >>> runSnippet(''' ... ''') >>> content = Content() >>> a1 = A1() >>> a2 = A2() >>> a3 = ProxyFactory(zope.component.queryMultiAdapter((content, a1, a2), I3)) >>> a3.__class__ == A3 True >>> [item[0] for item in getTestProxyItems(a3)] ['f1', 'f2', 'f3'] It's probably not worth mentioning, but when we try to protect an adapter with a permission that doesn't exist, we'll obviously get an error: >>> clearZCML() >>> runSnippet(''' ... ''') Traceback (most recent call last): ... ConfigurationExecutionError: exceptions.ValueError: ('Undefined permission id', 'zope.UndefinedPermission') in: File "", line 4.2-9.8 Could not read source. Trusted adapters ~~~~~~~~~~~~~~~~ Trusted adapters are adapters that are trusted to do anything with the objects they are given so that these objects are not security-proxied. They are registered using the ``trusted`` argument to the directive: >>> clearZCML() >>> runSnippet(''' ... ''') With an unproxied object, it's business as usual: >>> ob = Content() >>> type(I1(ob)) is A1 True With a security-proxied object, however, we get a security-proxied adapter: >>> p = ProxyFactory(ob) >>> a = I1(p) >>> type(a) While the adapter is security-proxied, the object it adapts is now proxy-free. The adapter has umlimited access to it: >>> a = removeSecurityProxy(a) >>> type(a) is A1 True >>> a.context[0] is ob True We can also protect the trusted adapter with a permission: >>> clearZCML() >>> XMLConfig('meta.zcml', zope.security)() >>> runSnippet(''' ... ... ''') Again, with an unproxied object, it's business as usual: >>> ob = Content() >>> type(I1(ob)) is A1 True With a security-proxied object, we again get a security-proxied adapter: >>> p = ProxyFactory(ob) >>> a = I1(p) >>> type(a) Since we protected the adapter with a permission, we now encounter a location proxy behind the security proxy: >>> a = removeSecurityProxy(a) >>> type(a) >>> a.context[0] is ob True There's one exception to all of this: When you use the public permission (``zope.Public``), there will be no location proxy: >>> clearZCML() >>> runSnippet(''' ... ''') >>> ob = Content() >>> p = ProxyFactory(ob) >>> a = I1(p) >>> type(a) >>> a = removeSecurityProxy(a) >>> type(a) is A1 True We can also explicitply pass the ``locate`` argument to make sure we get location proxies: >>> clearZCML() >>> runSnippet(''' ... ''') >>> ob = Content() >>> p = ProxyFactory(ob) >>> a = I1(p) >>> type(a) >>> a = removeSecurityProxy(a) >>> type(a) subscriber ---------- With the directive you can register subscription adapters or event subscribers with the adapter registry. Consider this very typical example of a directive: >>> clearZCML() >>> runSnippet(''' ... ''') >>> content = Content() >>> a1 = A1() >>> subscribers = zope.component.subscribers((content, a1), IS) >>> a3 = subscribers[0] >>> a3.__class__ is A3 True >>> a3.context == (content, a1) True Note how ZCML provides some additional information when registering components, such as the ZCML filename and line numbers: >>> sm = zope.component.getSiteManager() >>> doc = [reg.info for reg in sm.registeredSubscriptionAdapters() ... if reg.provided is IS][0] >>> print doc File "", line 4.2-9.8 Could not read source. The "fun" behind subscription adapters/subscribers is that when several ones are declared for the same for/provides, they are all found. With regular adapters, the most specific one (and in doubt the one registered last) wins. Consider these two subscribers: >>> clearZCML() >>> runSnippet(''' ... ... ''') >>> subscribers = zope.component.subscribers((content, a1), IS) >>> len(subscribers) 2 >>> sorted([a.__class__.__name__ for a in subscribers]) ['A2', 'A3'] Declaring ``for`` and ``provides`` in Python ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Like the directive, the directive can figure out from the in-line Python declaration (using ``zope.component.adapts()`` or ``zope.component.adapter()``) what the subscriber should be registered for: >>> clearZCML() >>> runSnippet(''' ... ''') >>> content = Content() >>> a2 = A2() >>> subscribers = zope.component.subscribers((content, a1, a2), IS) >>> a3 = subscribers[0] >>> a3.__class__ is A3 True >>> a3.context == (content, a1, a2) True In the same way the directive can figure out what a subscriber provides: >>> clearZCML() >>> runSnippet(''' ... ''') >>> sm = zope.component.getSiteManager() >>> a3 = sm.adapters.subscriptions((IContent, I1, I2), None)[0] >>> a3 is A3 True A not so common edge case is declaring subscribers directly for classes, not for interfaces. For example: >>> clearZCML() >>> runSnippet(''' ... ''') >>> subs = list(zope.component.subscribers((Content(),), I1)) >>> isinstance(subs[0], A1) True This time, any object providing ``IContent`` won't work if it's not an instance of the ``Content`` class: >>> list(zope.component.subscribers((MyContent(),), I1)) [] Protected subscribers ~~~~~~~~~~~~~~~~~~~~~ Subscribers can also be protected with a permission. First we have to define a permission for which we'll have to register the directive: >>> clearZCML() >>> XMLConfig('meta.zcml', zope.security)() >>> runSnippet(''' ... ... ''') >>> subscribers = zope.component.subscribers((content, a1), IS) >>> a3 = subscribers[0] >>> a3.__class__ is A3 True >>> type(a3) >>> a3.context == (content, a1) True Trusted subscribers ~~~~~~~~~~~~~~~~~~~ Like trusted adapters, trusted subscribers are subscribers that are trusted to do anything with the objects they are given so that these objects are not security-proxied. In analogy to the directive, they are registered using the ``trusted`` argument to the directive: >>> clearZCML() >>> runSnippet(''' ... ''') With an unproxied object, it's business as usual: >>> subscribers = zope.component.subscribers((content, a1), IS) >>> a3 = subscribers[0] >>> a3.__class__ is A3 True >>> a3.context == (content, a1) True >>> type(a3) is A3 True Now with a proxied object. We will see that the subscriber has unproxied access to it, but the subscriber itself is proxied: >>> p = ProxyFactory(content) >>> a3 = zope.component.subscribers((p, a1), IS)[0] >>> type(a3) There's no location proxy behind the security proxy: >>> removeSecurityProxy(a3).context[0] is content True >>> type(removeSecurityProxy(a3)) is A3 True If you want the trusted subscriber to be located, you'll also have to use the ``locate`` argument: >>> clearZCML() >>> runSnippet(''' ... ''') Again, it's business as usual with an unproxied object: >>> subscribers = zope.component.subscribers((content, a1), IS) >>> a3 = subscribers[0] >>> a3.__class__ is A3 True >>> a3.context == (content, a1) True >>> type(a3) is A3 True With a proxied object, we again get a security-proxied subscriber: >>> p = ProxyFactory(content) >>> a3 = zope.component.subscribers((p, a1), IS)[0] >>> type(a3) >>> removeSecurityProxy(a3).context[0] is content True However, thanks to the ``locate`` argument, we now have a location proxy behind the security proxy: >>> type(removeSecurityProxy(a3)) Event subscriber (handlers) ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Sometimes, subscribers don't need to be adapters that actually provide anything. It's enough that a callable is called for a certain event. >>> clearZCML() >>> runSnippet(''' ... ''') In this case, simply getting the subscribers is enough to invoke them: >>> list(zope.component.subscribers((content, a1), None)) [] >>> content.args == ((a1,),) True utility ------- Apart from adapters (and subscription adapters), the Component Architecture knows a second kind of component: utilities. They are registered using the directive. Before we register the first test utility, we can verify that utility lookup doesn't work yet: >>> clearZCML() >>> zope.component.queryUtility(IApp) is None True Then we register the utility: >>> runSnippet(''' ... ''') >>> zope.component.getUtility(IApp) is comp True Like adapters, utilities can also have names. There can be more than one utility registered for a certain interface, as long as they each have a different name. First, we make sure that there's no utility yet: >>> clearZCML() >>> zope.component.queryUtility(IApp, 'test') is None True Then we register it: >>> runSnippet(''' ... ''') >>> zope.component.getUtility(IApp, 'test') is comp True Utilities can also be registered from a factory. In this case, the ZCML handler calls the factory (without any arguments) and registers the returned value as a utility. Typically, you'd pass a class for the factory: >>> clearZCML() >>> zope.component.queryUtility(IApp) is None True >>> runSnippet(''' ... ''') >>> zope.component.getUtility(IApp).__class__ is Comp True Declaring ``provides`` in Python ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Like other directives, can also figure out which interface a utility provides from the Python declaration: >>> clearZCML() >>> zope.component.queryUtility(IApp) is None True >>> runSnippet(''' ... ''') >>> zope.component.getUtility(IApp) is comp True It won't work if the component that is to be registered doesn't provide anything: >>> clearZCML() >>> runSnippet(''' ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 4.2-4.61 TypeError: Missing 'provides' attribute Or if more than one interface is provided (then the ZCML directive handler doesn't know under which the utility should be registered): >>> clearZCML() >>> runSnippet(''' ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 4.2-4.61 TypeError: Missing 'provides' attribute We can repeat the same drill for utility factories: >>> clearZCML() >>> runSnippet(''' ...

ZopeXMLConfigurationError: File "", line 4.2-4.59 TypeError: Missing 'provides' attribute >>> clearZCML() >>> runSnippet(''' ... ''') Traceback (most recent call last): ...

Interfaces are registered as named utilities. We therefore needn't go though all the lookup details again, it is sufficient to see whether the directive handler emits the right actions. First we provide a stub configuration context: >>> import re, pprint >>> atre = re.compile(' at [0-9a-fA-Fx]+') >>> class Context(object): ... actions = () ... def action(self, discriminator, callable, args): ... self.actions += ((discriminator, callable, args), ) ... def __repr__(self): ... stream = StringIO() ... pprinter = pprint.PrettyPrinter(stream=stream, width=60) ... pprinter.pprint(self.actions) ... r = stream.getvalue() ... return (''.join(atre.split(r))).strip() >>> context = Context() Then we provide a test interface that we'd like to register: >>> from zope.interface import Interface >>> class I(Interface): ... pass It doesn't yet provide ``ITestType``: >>> from zope.component.tests import ITestType >>> ITestType.providedBy(I) False However, after calling the directive handler... >>> from zope.component.zcml import interface >>> interface(context, I, ITestType) >>> context ((None, , ('', , )),) ...it does provide ``ITestType``: >>> from zope.interface.interfaces import IInterface >>> ITestType.extends(IInterface) True >>> IInterface.providedBy(I) True zope2.13-2.13.21/source/zope.component/src/zope/component/event.txt0000644000175000017500000000643712214017426024056 0ustar arnauarnauEvents ====== The Component Architecture provides a way to dispatch events to event handlers. Event handlers are registered as *subscribers* a.k.a. *handlers*. Before we can start we need to import ``zope.component.event`` to make the dispatching effective: >>> import zope.component.event Consider two event classes: >>> class Event1(object): ... pass >>> class Event2(Event1): ... pass Now consider two handlers for these event classes: >>> called = [] >>> import zope.component >>> @zope.component.adapter(Event1) ... def handler1(event): ... called.append(1) >>> @zope.component.adapter(Event2) ... def handler2(event): ... called.append(2) We can register them with the Component Architecture: >>> zope.component.provideHandler(handler1) >>> zope.component.provideHandler(handler2) Now let's go through the events. We'll see that the handlers have been called accordingly: >>> from zope.event import notify >>> notify(Event1()) >>> called [1] >>> del called[:] >>> notify(Event2()) >>> called.sort() >>> called [1, 2] Object events ------------- The ``objectEventNotify`` function is a subscriber to dispatch ObjectEvents to interested adapters. First create an object class: >>> class IUseless(zope.interface.Interface): ... """Useless object""" >>> class UselessObject(object): ... """Useless object""" ... zope.interface.implements(IUseless) Then create an event class: >>> class IObjectThrownEvent(zope.component.interfaces.IObjectEvent): ... """An object has been thrown away""" >>> class ObjectThrownEvent(zope.component.interfaces.ObjectEvent): ... """An object has been thrown away""" ... zope.interface.implements(IObjectThrownEvent) Create an object and an event: >>> hammer = UselessObject() >>> event = ObjectThrownEvent(hammer) Then notify the event to the subscribers. Since the subscribers list is empty, nothing happens. >>> zope.component.event.objectEventNotify(event) Now create an handler for the event: >>> events = [] >>> def record(*args): ... events.append(args) >>> zope.component.provideHandler(record, [IUseless, IObjectThrownEvent]) The event is notified to the subscriber: >>> zope.component.event.objectEventNotify(event) >>> events == [(hammer, event)] True Following test demonstrates how a subscriber can raise an exception to prevent an action. >>> zope.component.provideHandler(zope.component.event.objectEventNotify) Let's create a container: >>> class ToolBox(dict): ... def __delitem__(self, key): ... notify(ObjectThrownEvent(self[key])) ... return super(ToolBox,self).__delitem__(key) >>> container = ToolBox() And put the object into the container: >>> container['Red Hammer'] = hammer Create an handler function that will raise an error when called: >>> class Veto(Exception): ... pass >>> def callback(item, event): ... assert(item == event.object) ... raise Veto Register the handler: >>> zope.component.provideHandler(callback, [IUseless, IObjectThrownEvent]) Then if we try to remove the object, an ObjectThrownEvent is fired: >>> del container['Red Hammer'] ... # doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... raise Veto Veto zope2.13-2.13.21/source/zope.component/src/zope/component/hooks.py0000644000175000017500000000721212214017426023661 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

One of them is the global component registry, and there is also the concept of a currently used component registry. Component registries other than the global one are associated with objects called sites. The ``zope.component.hooks`` module provides an API to set and access the current site as well as manipulate the adapter hook associated with it. As long as we haven't set a site, none is being considered current: >>> from zope.component.hooks import getSite >>> print getSite() None We can also ask for the current component registry (aka site manager historically); it will return the global one if no current site is set: >>> from zope.component.hooks import getSiteManager >>> getSiteManager() Let's set a site now. A site has to be an object that provides the ``getSiteManager`` method, which is specified by ``zope.component.interfaces.IPossibleSite``: >>> from zope.component.registry import Components >>> class Site(object): ... def __init__(self): ... self.registry = Components('components') ... def getSiteManager(self): ... return self.registry >>> from zope.component.hooks import setSite >>> site1 = Site() >>> setSite(site1) After this, the newly set site is considered the currently active one: >>> getSite() is site1 True >>> getSiteManager() is site1.registry True If we set another site, that one will be considered current: >>> site2 = Site() >>> site2.registry is not site1.registry True >>> setSite(site2) >>> getSite() is site2 True >>> getSiteManager() is site2.registry True Finally we can unset the site and the global component registry is used again: >>> setSite() >>> print getSite() None >>> getSiteManager() zope2.13-2.13.21/source/zope.component/src/zope/component/eventtesting.py0000644000175000017500000000353612214017426025262 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

These methods are supposed to be @classmethods and should not use super() as the test runner is supposed to take care of that. In practice, this mechanism turns out not to be useful and overcomplicated. It becomes difficult to pass information into layers (such as a ZCML file to load), because the only way to pass in information is to subclass, and subclassing these layers leads to a range of interactions that is hard to reason about. We'd rather just use Python and the super mechanism, as we know how to reason about that. This base class is a hack to make this possible. The hack requires us to set __bases__, __module__ and __name__. This fools zope.testing into thinking that this layer instance is a class it can work with.

There are two basic kinds of components: adapters and utilities. Utilities --------- Utilities are just components that provide an interface and that are looked up by an interface and a name. Let's look at a trivial utility definition: >>> from zope import interface >>> class IGreeter(interface.Interface): ... def greet(): ... "say hello" >>> class Greeter: ... interface.implements(IGreeter) ... ... def __init__(self, other="world"): ... self.other = other ... ... def greet(self): ... print "Hello", self.other We can register an instance this class using `provideUtility` [1]_: >>> from zope import component >>> greet = Greeter('bob') >>> component.provideUtility(greet, IGreeter, 'robert') In this example we registered the utility as providing the `IGreeter` interface with a name of 'bob'. We can look the interface up with either `queryUtility` or `getUtility`: >>> component.queryUtility(IGreeter, 'robert').greet() Hello bob >>> component.getUtility(IGreeter, 'robert').greet() Hello bob `queryUtility` and `getUtility` differ in how failed lookups are handled: >>> component.queryUtility(IGreeter, 'ted') >>> component.queryUtility(IGreeter, 'ted', 42) 42 >>> component.getUtility(IGreeter, 'ted') ... # doctest: +ELLIPSIS Traceback (most recent call last): ... ComponentLookupError: (, 'ted') If a component provides only one interface, as in the example above, then we can omit the provided interface from the call to `provideUtility`: >>> ted = Greeter('ted') >>> component.provideUtility(ted, name='ted') >>> component.queryUtility(IGreeter, 'ted').greet() Hello ted The name defaults to an empty string: >>> world = Greeter() >>> component.provideUtility(world) >>> component.queryUtility(IGreeter).greet() Hello world Adapters -------- Adapters are components that are computed from other components to adapt them to some interface. Because they are computed from other objects, they are provided as factories, usually classes. Here, we'll create a greeter for persons, so we can provide personalized greetings for different people: >>> class IPerson(interface.Interface): ... name = interface.Attribute("Name") >>> class PersonGreeter: ... ... component.adapts(IPerson) ... interface.implements(IGreeter) ... ... def __init__(self, person): ... self.person = person ... ... def greet(self): ... print "Hello", self.person.name The class defines a constructor that takes an argument for every object adapted. We used `component.adapts` to declare what we adapt. We can find out if an object declares that it adapts anything using adaptedBy: >>> list(component.adaptedBy(PersonGreeter)) == [IPerson] True If an object makes no declaration, then None is returned: >>> component.adaptedBy(Greeter()) is None True If we declare the interfaces adapted and if we provide only one interface, as in the example above, then we can provide the adapter very simply [1]_: >>> component.provideAdapter(PersonGreeter) For adapters that adapt a single interface to a single interface without a name, we can get the adapter by simply calling the interface: >>> class Person: ... interface.implements(IPerson) ... ... def __init__(self, name): ... self.name = name >>> IGreeter(Person("Sally")).greet() Hello Sally We can also provide arguments to be very specific about what how to register the adapter. >>> class BobPersonGreeter(PersonGreeter): ... name = 'Bob' ... def greet(self): ... print "Hello", self.person.name, "my name is", self.name >>> component.provideAdapter( ... BobPersonGreeter, [IPerson], IGreeter, 'bob') The arguments can also be provided as keyword arguments: >>> class TedPersonGreeter(BobPersonGreeter): ... name = "Ted" >>> component.provideAdapter( ... factory=TedPersonGreeter, adapts=[IPerson], ... provides=IGreeter, name='ted') For named adapters, use `queryAdapter`, or `getAdapter`: >>> component.queryAdapter(Person("Sally"), IGreeter, 'bob').greet() Hello Sally my name is Bob >>> component.getAdapter(Person("Sally"), IGreeter, 'ted').greet() Hello Sally my name is Ted If an adapter can't be found, `queryAdapter` returns a default value and `getAdapter` raises an error: >>> component.queryAdapter(Person("Sally"), IGreeter, 'frank') >>> component.queryAdapter(Person("Sally"), IGreeter, 'frank', 42) 42 >>> component.getAdapter(Person("Sally"), IGreeter, 'frank') ... # doctest: +ELLIPSIS Traceback (most recent call last): ... ComponentLookupError: (...Person...>, <...IGreeter>, 'frank') Adapters can adapt multiple objects: >>> class TwoPersonGreeter: ... ... component.adapts(IPerson, IPerson) ... interface.implements(IGreeter) ... ... def __init__(self, person, greeter): ... self.person = person ... self.greeter = greeter ... ... def greet(self): ... print "Hello", self.person.name ... print "my name is", self.greeter.name >>> component.provideAdapter(TwoPersonGreeter) To look up a multi-adapter, use either `queryMultiAdapter` or `getMultiAdapter`: >>> component.queryMultiAdapter((Person("Sally"), Person("Bob")), ... IGreeter).greet() Hello Sally my name is Bob Adapters need not be classes. Any callable will do. We use the adapter decorator (in the Python 2.4 decorator sense) to declare that a callable object adapts some interfaces (or classes): >>> class IJob(interface.Interface): ... "A job" >>> class Job: ... interface.implements(IJob) >>> def personJob(person): ... return getattr(person, 'job', None) >>> personJob = interface.implementer(IJob)(personJob) >>> personJob = component.adapter(IPerson)(personJob) In Python 2.4, the example can be written: >>> @interface.implementer(IJob) ... @component.adapter(IPerson) ... def personJob(person): ... return getattr(person, 'job', None) which looks a bit nicer. In this example, the personJob function simply returns the person's `job` attribute if present, or None if it's not present. An adapter factory can return None to indicate that adaptation wasn't possible. Let's register this adapter and try it out: >>> component.provideAdapter(personJob) >>> sally = Person("Sally") >>> IJob(sally) # doctest: +ELLIPSIS Traceback (most recent call last): ... TypeError: ('Could not adapt', ... The adaptation failed because sally didn't have a job. Let's give her one: >>> job = Job() >>> sally.job = job >>> IJob(sally) is job True Subscription Adapters --------------------- Unlike regular adapters, subscription adapters are used when we want all of the adapters that adapt an object to a particular adapter. Consider a validation problem. We have objects and we want to assess whether they meet some sort of standards. We define a validation interface: >>> class IValidate(interface.Interface): ... def validate(ob): ... """Determine whether the object is valid ... ... Return a string describing a validation problem. ... An empty string is returned to indicate that the ... object is valid. ... """ Perhaps we have documents: >>> class IDocument(interface.Interface): ... summary = interface.Attribute("Document summary") ... body = interface.Attribute("Document text") >>> class Document: ... interface.implements(IDocument) ... def __init__(self, summary, body): ... self.summary, self.body = summary, body Now, we may want to specify various validation rules for documents. For example, we might require that the summary be a single line: >>> class SingleLineSummary: ... component.adapts(IDocument) ... interface.implements(IValidate) ... ... def __init__(self, doc): ... self.doc = doc ... ... def validate(self): ... if '\n' in self.doc.summary: ... return 'Summary should only have one line' ... else: ... return '' Or we might require the body to be at least 1000 characters in length: >>> class AdequateLength: ... component.adapts(IDocument) ... interface.implements(IValidate) ... ... def __init__(self, doc): ... self.doc = doc ... ... def validate(self): ... if len(self.doc.body) < 1000: ... return 'too short' ... else: ... return '' We can register these as subscription adapters [1]_: >>> component.provideSubscriptionAdapter(SingleLineSummary) >>> component.provideSubscriptionAdapter(AdequateLength) We can then use the subscribers to validate objects: >>> doc = Document("A\nDocument", "blah") >>> [adapter.validate() ... for adapter in component.subscribers([doc], IValidate) ... if adapter.validate()] ['Summary should only have one line', 'too short'] >>> doc = Document("A\nDocument", "blah" * 1000) >>> [adapter.validate() ... for adapter in component.subscribers([doc], IValidate) ... if adapter.validate()] ['Summary should only have one line'] >>> doc = Document("A Document", "blah") >>> [adapter.validate() ... for adapter in component.subscribers([doc], IValidate) ... if adapter.validate()] ['too short'] Handlers -------- Handlers are subscription adapter factories that don't produce anything. They do all of their work when called. Handlers are typically used to handle events. Event subscribers are different from other subscription adapters in that the caller of event subscribers doesn't expect to interact with them in any direct way. For example, an event publisher doesn't expect to get any return value. Because subscribers don't need to provide an API to their callers, it is more natural to define them with functions, rather than classes. For example, in a document-management system, we might want to record creation times for documents: >>> import datetime >>> def documentCreated(event): ... event.doc.created = datetime.datetime.utcnow() In this example, we have a function that takes an event and performs some processing. It doesn't actually return anything. This is a special case of a subscription adapter that adapts an event to nothing. All of the work is done when the adapter "factory" is called. We call subscribers that don't actually create anything "handlers". There are special APIs for registering and calling them. To register the subscriber above, we define a document-created event: >>> class IDocumentCreated(interface.Interface): ... doc = interface.Attribute("The document that was created") >>> class DocumentCreated: ... interface.implements(IDocumentCreated) ... ... def __init__(self, doc): ... self.doc = doc We'll also change our handler definition to: >>> def documentCreated(event): ... event.doc.created = datetime.datetime.utcnow() >>> documentCreated = component.adapter(IDocumentCreated)(documentCreated) Note that in Python 2.4, this can be written: >>> @component.adapter(IDocumentCreated) ... def documentCreated(event): ... event.doc.created = datetime.datetime.utcnow() This marks the handler as an adapter of `IDocumentCreated` events. Now we'll register the handler [1]_: >>> component.provideHandler(documentCreated) Now, if we can create an event and use the `handle` function to call handlers registered for the event: >>> component.handle(DocumentCreated(doc)) >>> doc.created.__class__.__name__ 'datetime' .. [1] CAUTION: This API should only be used from test or application-setup code. This API shouldn't be used by regular library modules, as component registration is a configuration activity. zope2.13-2.13.21/source/zope.component/src/zope/component/event.py0000644000175000017500000000222712214017426023660 0ustar arnauarnau############################################################################## # # Copyright (c) 2004 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

LayerBase --------- We check whether our LayerBase can be used to create layers of our own. We do this simply by subclassing: >>> from zope.component.testlayer import LayerBase >>> class OurLayer(LayerBase): ... def setUp(self): ... super(OurLayer, self).setUp() ... print "setUp called" ... def tearDown(self): ... super(OurLayer, self).tearDown() ... print "tearDown called" ... def testSetUp(self): ... super(OurLayer, self).testSetUp() ... print "testSetUp called" ... def testTearDown(self): ... super(OurLayer, self).testTearDown() ... print "testTearDown called" Note that if we wanted to ensure that the methods of the superclass were called we have to use super(). In this case we actually wouldn't need to, as these methods do nothing at all, but we just ensure that they are there in the first place. Let's instantiate our layer. We need to supply it with the package the layer is defined in:: >>> import zope.component >>> layer = OurLayer(zope.component) Now we run some tests with this layer: >>> import unittest >>> class TestCase(unittest.TestCase): ... layer = layer ... ... def testFoo(self): ... print "testFoo" >>> suite = unittest.TestSuite() >>> suite.addTest(unittest.makeSuite(TestCase)) >>> from zope.testing.testrunner.runner import Runner >>> runner = Runner(args=[], found_suites=[suite]) >>> succeeded = runner.run() Running zope.component.OurLayer tests: Set up zope.component.OurLayer setUp called in ... seconds. testSetUp called testFoo testTearDown called Ran 1 tests with 0 failures and 0 errors in ... seconds. Tearing down left over layers: Tear down zope.component.OurLayer tearDown called in ... seconds. ZCMLLayer --------- We now want a layer that loads up some ZCML from a file. The default is ``ftesting.zcml``, but here we'll load a test ``testlayer.zcml``. >>> from zope.component.testlayer import ZCMLFileLayer >>> zcml_file_layer = ZCMLFileLayer( ... zope.component.testfiles, ... 'testlayer.zcml') >>> class TestCase(unittest.TestCase): ... layer = zcml_file_layer ... ... def testFoo(self): ... # we should now have the adapter registered ... from zope import component ... from zope.component.testfiles import components ... self.assert_(isinstance( ... components.IApp2(components.content), components.Comp2)) Since the ZCML sets up an adapter, we expect the tests to pass:: >>> suite = unittest.TestSuite() >>> suite.addTest(unittest.makeSuite(TestCase)) >>> runner = Runner(args=[], found_suites=[suite]) >>> succeeded = runner.run() Running zope.component.testfiles.ZCMLFileLayer tests: Set up zope.component.testfiles.ZCMLFileLayer in ... seconds.

A *component* can be any Python object and has a particular purpose associated with it. Thus, in a component-based applications you have many small component in contrast to classical object-oriented development, where you have a few big objects. Components communicate via specific APIs, which are formally defined by interfaces, which are provided by the `zope.interface` package. *Interfaces* describe the methods and properties that a component is expected to provide. They are also used as a primary mean to provide developer-level documentation for the components. For more details about interfaces see `zope/interface/README.txt`. The two main types of components are *adapters* and *utilities*. They will be discussed in detail later in this document. Both component types are managed by the *site manager*, with which you can register and access these components. However, most of the site manager's functionality is hidden behind the component architecture's public API, which is documented in `IComponentArchitecture`. Adapters -------- Adapters are a well-established pattern. An *adapter* uses an object providing one interface to produce an object that provides another interface. Here an example: Imagine that you purchased an electric shaver in the US, and thus you require the US socket type. You are now traveling in Germany, where another socket style is used. You will need a device, an adapter, that converts from the German to the US socket style. The functionality of adapters is actually natively provided by the `zope.interface` package and is thus well documented there. The `human.txt` file provides a gentle introduction to adapters, whereby `adapter.txt` is aimed at providing a comprehensive insight into adapters, but is too abstract for many as an initial read. Thus, we will only explain adapters in the context of the component architecture's API. So let's say that we have a German socket >>> from zope.interface import Interface, implements >>> class IGermanSocket(Interface): ... pass >>> class Socket(object): ... def __repr__(self): ... return '' %self.__class__.__name__ >>> class GermanSocket(Socket): ... """German wall socket.""" ... implements(IGermanSocket) and we want to convert it to an US socket >>> class IUSSocket(Interface): ... pass so that our shaver can be used in Germany. So we go to a German electronics store to look for an adapter that we can plug in the wall: >>> class GermanToUSSocketAdapter(Socket): ... implements(IUSSocket) ... __used_for__ = IGermanSocket ... ... def __init__(self, socket): ... self.context = socket Note that I could have called the passed in socket any way I like, but `context` is the standard name accepted. Single Adapters ~~~~~~~~~~~~~~~ Before we can use the adapter, we have to buy it and make it part of our inventory. In the component architecture we do this by registering the adapter with the framework, more specifically with the global site manager: >>> import zope.component >>> gsm = zope.component.getGlobalSiteManager() >>> gsm.registerAdapter(GermanToUSSocketAdapter, (IGermanSocket,), IUSSocket) `zope.component` is the component architecture API that is being presented by this file. You registered an adapter from `IGermanSocket` to `IUSSocket` having no name (thus the empty string). Anyways, you finally get back to your hotel room and shave, since you have not been able to shave in the plane. In the bathroom you discover a socket: >>> bathroomDE = GermanSocket() >>> IGermanSocket.providedBy(bathroomDE) True You now insert the adapter in the German socket >>> bathroomUS = zope.component.getAdapter(bathroomDE, IUSSocket, '') so that the socket now provides the US version: >>> IUSSocket.providedBy(bathroomUS) True Now you can insert your shaver and get on with your day. After a week you travel for a couple of days to the Prague and you notice that the Czech have yet another socket type: >>> class ICzechSocket(Interface): ... pass >>> class CzechSocket(Socket): ... implements(ICzechSocket) >>> czech = CzechSocket() You try to find an adapter for your shaver in your bag, but you fail, since you do not have one: >>> zope.component.getAdapter(czech, IUSSocket, '') \ ... #doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: (, , '') or the more graceful way: >>> marker = object() >>> socket = zope.component.queryAdapter(czech, IUSSocket, '', marker) >>> socket is marker True In the component architecture API any `get*` method will fail with a specific exception, if a query failed, whereby methods starting with `query*` will always return a `default` value after a failure. Named Adapters ~~~~~~~~~~~~~~ You are finally back in Germany. You also brought your DVD player and a couple DVDs with you, which you would like to watch. Your shaver was able to convert automatically from 110 volts to 240 volts, but your DVD player cannot. So you have to buy another adapter that also handles converting the voltage and the frequency of the AC current: >>> class GermanToUSSocketAdapterAndTransformer(object): ... implements(IUSSocket) ... __used_for__ = IGermanSocket ... ... def __init__(self, socket): ... self.context = socket Now, we need a way to keep the two adapters apart. Thus we register them with a name: >>> gsm.registerAdapter(GermanToUSSocketAdapter, ... (IGermanSocket,), IUSSocket, 'shaver',) >>> gsm.registerAdapter(GermanToUSSocketAdapterAndTransformer, ... (IGermanSocket,), IUSSocket, 'dvd') Now we simply look up the adapters using their labels (called *name*): >>> socket = zope.component.getAdapter(bathroomDE, IUSSocket, 'shaver') >>> socket.__class__ is GermanToUSSocketAdapter True >>> socket = zope.component.getAdapter(bathroomDE, IUSSocket, 'dvd') >>> socket.__class__ is GermanToUSSocketAdapterAndTransformer True Clearly, we do not have an adapter for the MP3 player >>> zope.component.getAdapter(bathroomDE, IUSSocket, 'mp3') \ ... #doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: (, , 'mp3') but you could use the 'dvd' adapter in this case of course. ;) Sometimes you want to know all adapters that are available. Let's say you want to know about all the adapters that convert a German to a US socket type: >>> sockets = list(zope.component.getAdapters((bathroomDE,), IUSSocket)) >>> len(sockets) 3 >>> names = [name for name, socket in sockets] >>> names.sort() >>> names [u'', u'dvd', u'shaver'] `zope.component.getAdapters()` returns a list of tuples. The first entry of the tuple is the name of the adapter and the second is the adapter itself. Multi-Adapters ~~~~~~~~~~~~~~ After watching all the DVDs you brought at least twice, you get tired of them and you want to listen to some music using your MP3 player. But darn, the MP3 player plug has a ground pin and all the adapters you have do not support that: >>> class IUSGroundedSocket(IUSSocket): ... pass So you go out another time to buy an adapter. This time, however, you do not buy yet another adapter, but a piece that provides the grounding plug: >>> class IGrounder(Interface): ... pass >>> class Grounder(object): ... implements(IGrounder) ... def __repr__(self): ... return '' Then together they will provided a grounded us socket: >>> class GroundedGermanToUSSocketAdapter(object): ... implements(IUSGroundedSocket) ... __used_for__ = (IGermanSocket, IGrounder) ... def __init__(self, socket, grounder): ... self.socket, self.grounder = socket, grounder You now register the combination, so that you know you can create a `IUSGroundedSocket`: >>> gsm.registerAdapter(GroundedGermanToUSSocketAdapter, ... (IGermanSocket, IGrounder), IUSGroundedSocket, 'mp3') Given the grounder >>> grounder = Grounder() and a German socket >>> livingroom = GermanSocket() we can now get a grounded US socket: >>> socket = zope.component.getMultiAdapter((livingroom, grounder), ... IUSGroundedSocket, 'mp3') >>> socket.__class__ is GroundedGermanToUSSocketAdapter True >>> socket.socket is livingroom True >>> socket.grounder is grounder True Of course, you do not have a 'dvd' grounded US socket available: >>> zope.component.getMultiAdapter((livingroom, grounder), ... IUSGroundedSocket, 'dvd') \ ... #doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: ((, ), , 'dvd') >>> socket = zope.component.queryMultiAdapter( ... (livingroom, grounder), IUSGroundedSocket, 'dvd', marker) >>> socket is marker True Again, you might want to read `adapter.txt` in `zope.interface` for a more comprehensive coverage of multi-adapters. Subscribers ----------- While subscribers are directly supported by the adapter registry and are adapters for all theoretical purposes, practically it might be better to think of them as separate components. Subscribers are particularly useful for events. Let's say one of our adapters overheated and caused a small fire: >>> class IFire(Interface): ... pass >>> class Fire(object): ... implements(IFire) >>> fire = Fire() We want to use all available objects to put out the fire: >>> class IFireExtinguisher(Interface): ... def extinguish(): ... pass >>> class FireExtinguisher(object): ... def __init__(self, fire): ... pass ... def extinguish(self): ... "Place extinguish code here." ... print 'Used ' + self.__class__.__name__ + '.' Here some specific methods to put out the fire: >>> class PowderExtinguisher(FireExtinguisher): ... pass >>> gsm.registerSubscriptionAdapter(PowderExtinguisher, ... (IFire,), IFireExtinguisher) >>> class Blanket(FireExtinguisher): ... pass >>> gsm.registerSubscriptionAdapter(Blanket, (IFire,), IFireExtinguisher) >>> class SprinklerSystem(FireExtinguisher): ... pass >>> gsm.registerSubscriptionAdapter(SprinklerSystem, ... (IFire,), IFireExtinguisher) Now let use all these things to put out the fire: >>> extinguishers = zope.component.subscribers((fire,), IFireExtinguisher) >>> extinguishers.sort() >>> for extinguisher in extinguishers: ... extinguisher.extinguish() Used Blanket. Used PowderExtinguisher. Used SprinklerSystem. If no subscribers are found for a particular object, then an empty list is returned: >>> zope.component.subscribers((object(),), IFireExtinguisher) [] Utilities --------- Utilities are the second type of component, the component architecture implements. *Utilities* are simply components that provide an interface. When you register an utility, you always register an instance (in contrast to a factory for adapters) since the initialization and setup process of a utility might be complex and is not well defined. In some ways a utility is much more fundamental than an adapter, because an adapter cannot be used without another component, but a utility is always self-contained. I like to think of utilities as the foundation of your application and adapters as components extending beyond this foundation. Back to our story... After your vacation is over you fly back home to Tampa, Florida. But it is August now, the middle of the Hurricane season. And, believe it or not, you are worried that you will not be able to shave when the power goes out for several days. (You just hate wet shavers.) So you decide to go to your favorite hardware store and by a Diesel-powered electric generator. The generator provides of course a US-style socket: >>> class Generator(object): ... implements(IUSSocket) ... def __repr__(self): ... return '' >>> generator = Generator() Like for adapters, we now have to add the newly-acquired generator to our inventory by registering it as a utility: >>> gsm.registerUtility(generator, IUSSocket) We can now get the utility using >>> utility = zope.component.getUtility(IUSSocket) >>> utility is generator True As you can see, it is very simple to register and retrieve utilities. If a utility does not exist for a particular interface, such as the German socket, then the lookup fails >>> zope.component.getUtility(IGermanSocket) Traceback (most recent call last): ... ComponentLookupError: (, '') or more gracefully when specifying a default value: >>> default = object() >>> utility = zope.component.queryUtility(IGermanSocket, default=default) >>> utility is default True Note: The only difference between `getUtility()` and `queryUtility()` is the fact that you can specify a default value for the latter function, so that it will never cause a `ComponentLookupError`. Named Utilities ~~~~~~~~~~~~~~~ It is often desirable to have several utilities providing the same interface per site. This way you can implement any sort of registry using utilities. For this reason, utilities -- like adapters -- can be named. In the context of our story, we might want to do the following: You really do not trust gas stations either. What if the roads are blocked after a hurricane and the gas stations run out of oil. So you look for another renewable power source. Then you think about solar panels! After a storm there is usually very nice weather, so why not? Via the Web you order a set of 110V/120W solar panels that provide a regular US-style socket as output: >>> class SolarPanel(object): ... implements(IUSSocket) ... def __repr__(self): ... return '' >>> panel = SolarPanel() Once it arrives, we add it to our inventory: >>> gsm.registerUtility(panel, IUSSocket, 'Solar Panel') You can now access the solar panel using >>> utility = zope.component.getUtility(IUSSocket, 'Solar Panel') >>> utility is panel True Of course, if a utility is not available, then the lookup will simply fail >>> zope.component.getUtility(IUSSocket, 'Wind Mill') Traceback (most recent call last): ... ComponentLookupError: (, 'Wind Mill') or more gracefully when specifying a default value: >>> default = object() >>> utility = zope.component.queryUtility(IUSSocket, 'Wind Mill', ... default=default) >>> utility is default True Now you want to look at all the utilities you have for a particular kind. The following API function will return a list of name/utility pairs: >>> utils = list(zope.component.getUtilitiesFor(IUSSocket)) >>> utils.sort() >>> utils #doctest: +NORMALIZE_WHITESPACE [(u'', ), (u'Solar Panel', )] Another method of looking up all utilities is by using `getAllUtilitiesRegisteredFor(iface)`. This function will return an iterable of utilities (without names); however, it will also return overridden utilities. If you are not using multiple site managers, you will not actually need this method. >>> utils = list(zope.component.getAllUtilitiesRegisteredFor(IUSSocket)) >>> utils.sort() >>> utils [, ] Factories ~~~~~~~~~ A *factory* is a special kind of utility that exists to create other components. A factory is always identified by a name. It also provides a title and description and is able to tell the developer what interfaces the created object will provide. The advantage of using a factory to create an object instead of directly instantiating a class or executing any other callable is that we can refer to the factory by name. As long as the name stays fixed, the implementation of the callable can be renamed or moved without a breakage in code. Let's say that our solar panel comes in parts and they have to be assembled. This assembly would be done by a factory, so let's create one for the solar panel. To do this, we can use a standard implementation of the `IFactory` interface: >>> from zope.component.factory import Factory >>> factory = Factory(SolarPanel, ... 'Solar Panel', ... 'This factory creates a solar panel.') Optionally, I could have also specified the interfaces that the created object will provide, but the factory class is smart enough to determine the implemented interface from the class. We now register the factory: >>> from zope.component.interfaces import IFactory >>> gsm.registerUtility(factory, IFactory, 'SolarPanel') We can now get a list of interfaces the produced object will provide: >>> ifaces = zope.component.getFactoryInterfaces('SolarPanel') >>> IUSSocket in ifaces True By the way, this is equivalent to >>> ifaces2 = factory.getInterfaces() >>> ifaces is ifaces2 True Of course you can also just create an object: >>> panel = zope.component.createObject('SolarPanel') >>> panel.__class__ is SolarPanel True Note: Ignore the first argument (`None`) for now; it is the context of the utility lookup, which is usually an optional argument, but cannot be in this case, since all other arguments beside the `name` are passed in as arguments to the specified callable. Once you register several factories >>> gsm.registerUtility(Factory(Generator), IFactory, 'Generator') you can also determine, which available factories will create objects providing a certain interface: >>> factories = zope.component.getFactoriesFor(IUSSocket) >>> factories = [(name, factory.__class__) for name, factory in factories] >>> factories.sort() >>> factories #doctest: +NORMALIZE_WHITESPACE [(u'Generator', ), (u'SolarPanel', )] Site Managers ------------- Why do we need site managers? Why is the component architecture API not sufficient? Some applications, including Zope 3, have a concept of locations. It is often desirable to have different configurations for these location; this can be done by overwriting existing or adding new component registrations. Site managers in locations below the root location, should be able to delegate requests to their parent locations. The root site manager is commonly known as *global site manager*, since it is always available. You can always get the global site manager using the API: >>> gsm = zope.component.getGlobalSiteManager() >>> from zope.component import globalSiteManager >>> gsm is globalSiteManager True >>> from zope.component.interfaces import IComponentLookup >>> IComponentLookup.providedBy(gsm) True >>> from zope.component.interfaces import IComponents >>> IComponents.providedBy(gsm) True You can also lookup at site manager in a given context. The only requirement is that the context can be adapted to a site manager. So let's create a special site manager: >>> from zope.component.globalregistry import BaseGlobalComponents >>> sm = BaseGlobalComponents() Now we create a context that adapts to the site manager via the `__conform__` method as specified in PEP 246. >>> class Context(object): ... def __init__(self, sm): ... self.sm = sm ... def __conform__(self, interface): ... if interface.isOrExtends(IComponentLookup): ... return self.sm We now instantiate the `Context` with our special site manager: >>> context = Context(sm) >>> context.sm is sm True We can now ask for the site manager of this context: >>> lsm = zope.component.getSiteManager(context) >>> lsm is sm True The site manager instance `lsm` is formally known as a *local site manager* of `context`. zope2.13-2.13.21/source/zope.component/src/zope/component/testfiles/0000755000175000017500000000000012214017426024164 5ustar arnauarnauzope2.13-2.13.21/source/zope.component/src/zope/component/testfiles/components.py0000644000175000017500000000260312214017426026724 0ustar arnauarnau############################################################################## # # Copyright (c) 2002 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

It is maintained by the* `Zope Toolkit project `_. This package represents the core of the Zope Component Architecture. Together with the 'zope.interface' package, it provides facilities for defining, registering and looking up components. .. contents:: Detailed Documentation ********************** Zope Component Architecture =========================== This package, together with `zope.interface`, provides facilities for defining, registering and looking up components. There are two basic kinds of components: adapters and utilities. Utilities --------- Utilities are just components that provide an interface and that are looked up by an interface and a name. Let's look at a trivial utility definition: >>> from zope import interface >>> class IGreeter(interface.Interface): ... def greet(): ... "say hello" >>> class Greeter: ... interface.implements(IGreeter) ... ... def __init__(self, other="world"): ... self.other = other ... ... def greet(self): ... print "Hello", self.other We can register an instance this class using `provideUtility` [1]_: >>> from zope import component >>> greet = Greeter('bob') >>> component.provideUtility(greet, IGreeter, 'robert') In this example we registered the utility as providing the `IGreeter` interface with a name of 'bob'. We can look the interface up with either `queryUtility` or `getUtility`: >>> component.queryUtility(IGreeter, 'robert').greet() Hello bob >>> component.getUtility(IGreeter, 'robert').greet() Hello bob `queryUtility` and `getUtility` differ in how failed lookups are handled: >>> component.queryUtility(IGreeter, 'ted') >>> component.queryUtility(IGreeter, 'ted', 42) 42 >>> component.getUtility(IGreeter, 'ted') ... # doctest: +ELLIPSIS Traceback (most recent call last): ... ComponentLookupError: (, 'ted') If a component provides only one interface, as in the example above, then we can omit the provided interface from the call to `provideUtility`: >>> ted = Greeter('ted') >>> component.provideUtility(ted, name='ted') >>> component.queryUtility(IGreeter, 'ted').greet() Hello ted The name defaults to an empty string: >>> world = Greeter() >>> component.provideUtility(world) >>> component.queryUtility(IGreeter).greet() Hello world Adapters -------- Adapters are components that are computed from other components to adapt them to some interface. Because they are computed from other objects, they are provided as factories, usually classes. Here, we'll create a greeter for persons, so we can provide personalized greetings for different people: >>> class IPerson(interface.Interface): ... name = interface.Attribute("Name") >>> class PersonGreeter: ... ... component.adapts(IPerson) ... interface.implements(IGreeter) ... ... def __init__(self, person): ... self.person = person ... ... def greet(self): ... print "Hello", self.person.name The class defines a constructor that takes an argument for every object adapted. We used `component.adapts` to declare what we adapt. We can find out if an object declares that it adapts anything using adaptedBy: >>> list(component.adaptedBy(PersonGreeter)) == [IPerson] True If an object makes no declaration, then None is returned: >>> component.adaptedBy(Greeter()) is None True If we declare the interfaces adapted and if we provide only one interface, as in the example above, then we can provide the adapter very simply [1]_: >>> component.provideAdapter(PersonGreeter) For adapters that adapt a single interface to a single interface without a name, we can get the adapter by simply calling the interface: >>> class Person: ... interface.implements(IPerson) ... ... def __init__(self, name): ... self.name = name >>> IGreeter(Person("Sally")).greet() Hello Sally We can also provide arguments to be very specific about what how to register the adapter. >>> class BobPersonGreeter(PersonGreeter): ... name = 'Bob' ... def greet(self): ... print "Hello", self.person.name, "my name is", self.name >>> component.provideAdapter( ... BobPersonGreeter, [IPerson], IGreeter, 'bob') The arguments can also be provided as keyword arguments: >>> class TedPersonGreeter(BobPersonGreeter): ... name = "Ted" >>> component.provideAdapter( ... factory=TedPersonGreeter, adapts=[IPerson], ... provides=IGreeter, name='ted') For named adapters, use `queryAdapter`, or `getAdapter`: >>> component.queryAdapter(Person("Sally"), IGreeter, 'bob').greet() Hello Sally my name is Bob >>> component.getAdapter(Person("Sally"), IGreeter, 'ted').greet() Hello Sally my name is Ted If an adapter can't be found, `queryAdapter` returns a default value and `getAdapter` raises an error: >>> component.queryAdapter(Person("Sally"), IGreeter, 'frank') >>> component.queryAdapter(Person("Sally"), IGreeter, 'frank', 42) 42 >>> component.getAdapter(Person("Sally"), IGreeter, 'frank') ... # doctest: +ELLIPSIS Traceback (most recent call last): ... ComponentLookupError: (...Person...>, <...IGreeter>, 'frank') Adapters can adapt multiple objects: >>> class TwoPersonGreeter: ... ... component.adapts(IPerson, IPerson) ... interface.implements(IGreeter) ... ... def __init__(self, person, greeter): ... self.person = person ... self.greeter = greeter ... ... def greet(self): ... print "Hello", self.person.name ... print "my name is", self.greeter.name >>> component.provideAdapter(TwoPersonGreeter) To look up a multi-adapter, use either `queryMultiAdapter` or `getMultiAdapter`: >>> component.queryMultiAdapter((Person("Sally"), Person("Bob")), ... IGreeter).greet() Hello Sally my name is Bob Adapters need not be classes. Any callable will do. We use the adapter decorator (in the Python 2.4 decorator sense) to declare that a callable object adapts some interfaces (or classes): >>> class IJob(interface.Interface): ... "A job" >>> class Job: ... interface.implements(IJob) >>> def personJob(person): ... return getattr(person, 'job', None) >>> personJob = interface.implementer(IJob)(personJob) >>> personJob = component.adapter(IPerson)(personJob) In Python 2.4, the example can be written: >>> @interface.implementer(IJob) ... @component.adapter(IPerson) ... def personJob(person): ... return getattr(person, 'job', None) which looks a bit nicer. In this example, the personJob function simply returns the person's `job` attribute if present, or None if it's not present. An adapter factory can return None to indicate that adaptation wasn't possible. Let's register this adapter and try it out: >>> component.provideAdapter(personJob) >>> sally = Person("Sally") >>> IJob(sally) # doctest: +ELLIPSIS Traceback (most recent call last): ... TypeError: ('Could not adapt', ... The adaptation failed because sally didn't have a job. Let's give her one: >>> job = Job() >>> sally.job = job >>> IJob(sally) is job True Subscription Adapters --------------------- Unlike regular adapters, subscription adapters are used when we want all of the adapters that adapt an object to a particular adapter. Consider a validation problem. We have objects and we want to assess whether they meet some sort of standards. We define a validation interface: >>> class IValidate(interface.Interface): ... def validate(ob): ... """Determine whether the object is valid ... ... Return a string describing a validation problem. ... An empty string is returned to indicate that the ... object is valid. ... """ Perhaps we have documents: >>> class IDocument(interface.Interface): ... summary = interface.Attribute("Document summary") ... body = interface.Attribute("Document text") >>> class Document: ... interface.implements(IDocument) ... def __init__(self, summary, body): ... self.summary, self.body = summary, body Now, we may want to specify various validation rules for documents. For example, we might require that the summary be a single line: >>> class SingleLineSummary: ... component.adapts(IDocument) ... interface.implements(IValidate) ... ... def __init__(self, doc): ... self.doc = doc ... ... def validate(self): ... if '\n' in self.doc.summary: ... return 'Summary should only have one line' ... else: ... return '' Or we might require the body to be at least 1000 characters in length: >>> class AdequateLength: ... component.adapts(IDocument) ... interface.implements(IValidate) ... ... def __init__(self, doc): ... self.doc = doc ... ... def validate(self): ... if len(self.doc.body) < 1000: ... return 'too short' ... else: ... return '' We can register these as subscription adapters [1]_: >>> component.provideSubscriptionAdapter(SingleLineSummary) >>> component.provideSubscriptionAdapter(AdequateLength) We can then use the subscribers to validate objects: >>> doc = Document("A\nDocument", "blah") >>> [adapter.validate() ... for adapter in component.subscribers([doc], IValidate) ... if adapter.validate()] ['Summary should only have one line', 'too short'] >>> doc = Document("A\nDocument", "blah" * 1000) >>> [adapter.validate() ... for adapter in component.subscribers([doc], IValidate) ... if adapter.validate()] ['Summary should only have one line'] >>> doc = Document("A Document", "blah") >>> [adapter.validate() ... for adapter in component.subscribers([doc], IValidate) ... if adapter.validate()] ['too short'] Handlers -------- Handlers are subscription adapter factories that don't produce anything. They do all of their work when called. Handlers are typically used to handle events. Event subscribers are different from other subscription adapters in that the caller of event subscribers doesn't expect to interact with them in any direct way. For example, an event publisher doesn't expect to get any return value. Because subscribers don't need to provide an API to their callers, it is more natural to define them with functions, rather than classes. For example, in a document-management system, we might want to record creation times for documents: >>> import datetime >>> def documentCreated(event): ... event.doc.created = datetime.datetime.utcnow() In this example, we have a function that takes an event and performs some processing. It doesn't actually return anything. This is a special case of a subscription adapter that adapts an event to nothing. All of the work is done when the adapter "factory" is called. We call subscribers that don't actually create anything "handlers". There are special APIs for registering and calling them. To register the subscriber above, we define a document-created event: >>> class IDocumentCreated(interface.Interface): ... doc = interface.Attribute("The document that was created") >>> class DocumentCreated: ... interface.implements(IDocumentCreated) ... ... def __init__(self, doc): ... self.doc = doc We'll also change our handler definition to: >>> def documentCreated(event): ... event.doc.created = datetime.datetime.utcnow() >>> documentCreated = component.adapter(IDocumentCreated)(documentCreated) Note that in Python 2.4, this can be written: >>> @component.adapter(IDocumentCreated) ... def documentCreated(event): ... event.doc.created = datetime.datetime.utcnow() This marks the handler as an adapter of `IDocumentCreated` events. Now we'll register the handler [1]_: >>> component.provideHandler(documentCreated) Now, if we can create an event and use the `handle` function to call handlers registered for the event: >>> component.handle(DocumentCreated(doc)) >>> doc.created.__class__.__name__ 'datetime' .. [1] CAUTION: This API should only be used from test or application-setup code. This API shouldn't be used by regular library modules, as component registration is a configuration activity. Events ====== The Component Architecture provides a way to dispatch events to event handlers. Event handlers are registered as *subscribers* a.k.a. *handlers*. Before we can start we need to import ``zope.component.event`` to make the dispatching effective: >>> import zope.component.event Consider two event classes: >>> class Event1(object): ... pass >>> class Event2(Event1): ... pass Now consider two handlers for these event classes: >>> called = [] >>> import zope.component >>> @zope.component.adapter(Event1) ... def handler1(event): ... called.append(1) >>> @zope.component.adapter(Event2) ... def handler2(event): ... called.append(2) We can register them with the Component Architecture: >>> zope.component.provideHandler(handler1) >>> zope.component.provideHandler(handler2) Now let's go through the events. We'll see that the handlers have been called accordingly: >>> from zope.event import notify >>> notify(Event1()) >>> called [1] >>> del called[:] >>> notify(Event2()) >>> called.sort() >>> called [1, 2] Object events ------------- The ``objectEventNotify`` function is a subscriber to dispatch ObjectEvents to interested adapters. First create an object class: >>> class IUseless(zope.interface.Interface): ... """Useless object""" >>> class UselessObject(object): ... """Useless object""" ... zope.interface.implements(IUseless) Then create an event class: >>> class IObjectThrownEvent(zope.component.interfaces.IObjectEvent): ... """An object has been thrown away""" >>> class ObjectThrownEvent(zope.component.interfaces.ObjectEvent): ...

In particular, it provides: - utilities - support for computing adapters, rather than just looking up adapter factories. - management of registration comments The zope.component.registry.Components class provides an implementation of zope.component.interfaces.IComponents that provides these features. >>> from zope.component import registry >>> from zope.component import tests >>> components = registry.Components('comps') As components are registered, events are generated.

This provides extra documentation about the registration itself that is shown when listing registrations. You can also unregister utilities: >>> components.unregisterUtility(provided=tests.I1) Unregistered event: UtilityRegistration(, I1, u'', 4, None, u'use 4 now') True A boolean is returned indicating whether anything changed: >>> components.queryUtility(tests.I1) >>> for registration in sorted(components.registeredUtilities()): ... print registration.provided, registration.name ... print registration.component, registration.info U12(2) three U12(3) When you unregister, you can specify a component.

They depend on being dispatched to by the object-event dispatcher: >>> from zope import component >>> import zope.component.event >>> zope.component.getGlobalSiteManager().registerHandler( ... zope.component.event.objectEventNotify) ... # doctest: +NORMALIZE_WHITESPACE Registered event: HandlerRegistration(, [IObjectEvent], u'', objectEventNotify, u'') To see this, we'll first register a multi-handler to show is when handlers are called on 2 objects: >>> @zope.component.adapter(None, None) ... def double_handler(o1, o2): ... print 'Double dispatch:' ... print ' ', o1 ... print ' ', o2 >>> zope.component.getGlobalSiteManager().registerHandler(double_handler) ... # doctest: +NORMALIZE_WHITESPACE Double dispatch: HandlerRegistration(, [Interface, Interface], u'', double_handler, u'') Registered event: HandlerRegistration(, [Interface, Interface], u'', double_handler, u'') Registered event: HandlerRegistration(, [Interface, Interface], u'', double_handler, u'') In the example above, the double_handler reported it's own registration. :) Now we'll register our handlers: >>> zope.component.getGlobalSiteManager().registerHandler( ... registry.dispatchUtilityRegistrationEvent) ... # doctest: +NORMALIZE_WHITESPACE +ELLIPSIS Double dispatch: ... >>> zope.component.getGlobalSiteManager().registerHandler( ... registry.dispatchAdapterRegistrationEvent) ... # doctest: +NORMALIZE_WHITESPACE +ELLIPSIS Double dispatch: ... >>> zope.component.getGlobalSiteManager().registerHandler( ... registry.dispatchSubscriptionAdapterRegistrationEvent) ... # doctest: +NORMALIZE_WHITESPACE +ELLIPSIS Double dispatch: ... >>> zope.component.getGlobalSiteManager().registerHandler( ... registry.dispatchHandlerRegistrationEvent) ... # doctest: +NORMALIZE_WHITESPACE Double dispatch: HandlerRegistration(, [IHandlerRegistration, IRegistrationEvent], u'', dispatchHandlerRegistrationEvent, u'') Registered event: HandlerRegistration(, [IHandlerRegistration, IRegistrationEvent], u'', dispatchHandlerRegistrationEvent, u'') Double dispatch: Registered event: HandlerRegistration(, [IHandlerRegistration, IRegistrationEvent], u'', dispatchHandlerRegistrationEvent, u'') Registered event: HandlerRegistration(, [IHandlerRegistration, IRegistrationEvent], u'', dispatchHandlerRegistrationEvent, u'') In the last example above, we can see that the registration of dispatchHandlerRegistrationEvent was handled by dispatchHandlerRegistrationEvent and redispatched. This can be seen in the second double-dispatch output, where the first argument is the object being registered, which is dispatchHandlerRegistrationEvent. If we change some other registrations, we can the double dispatch taking place: >>> components.registerUtility(u5) ... # doctest: +NORMALIZE_WHITESPACE Double dispatch: UtilityRegistration(, I1, u'', 5, None, u'') Registered event: UtilityRegistration(, I1, u'', 5, None, u'') Double dispatch: U1(5) Registered event: UtilityRegistration(, I1, u'', 5, None, u'') Registered event: UtilityRegistration(, I1, u'', 5, None, u'') >>> components.registerAdapter(tests.A12_1) ... # doctest: +NORMALIZE_WHITESPACE Double dispatch: AdapterRegistration(, [I1, I2], IA1, u'', A12_1, u'') Registered event: AdapterRegistration(, [I1, I2], IA1, u'', A12_1, u'') Double dispatch: zope.component.tests.A12_1 Registered event: AdapterRegistration(, [I1, I2], IA1, u'', A12_1, u'') Registered event: AdapterRegistration(, [I1, I2], IA1, u'', A12_1, u'') >>> components.registerSubscriptionAdapter(tests.A1_2) ... # doctest: +NORMALIZE_WHITESPACE Double dispatch: SubscriptionRegistration(, [I1], IA2, u'', A1_2, u'') Registered event: SubscriptionRegistration(, [I1], IA2, u'', A1_2, u'') Double dispatch: zope.component.tests.A1_2 Registered event: SubscriptionRegistration(, [I1], IA2, u'', A1_2, u'') Registered event: SubscriptionRegistration(, [I1], IA2, u'', A1_2, u'') Persistent Component Management =============================== Persistent component management allows persistent management of components. From a usage point of view, there shouldn't be any new behavior beyond what's described in registry.txt. The Zope 3 Component Architecture (Socket Example) ================================================== The component architecture provides an application framework that provides its functionality through loosely-connected components. A *component* can be any Python object and has a particular purpose associated with it. Thus, in a component-based applications you have many small component in contrast to classical object-oriented development, where you have a few big objects. Components communicate via specific APIs, which are formally defined by interfaces, which are provided by the `zope.interface` package. *Interfaces* describe the methods and properties that a component is expected to provide. They are also used as a primary mean to provide developer-level documentation for the components. For more details about interfaces see `zope/interface/README.txt`. The two main types of components are *adapters* and *utilities*. They will be discussed in detail later in this document. Both component types are managed by the *site manager*, with which you can register and access these components. However, most of the site manager's functionality is hidden behind the component architecture's public API, which is documented in `IComponentArchitecture`. Adapters -------- Adapters are a well-established pattern. An *adapter* uses an object providing one interface to produce an object that provides another interface. Here an example: Imagine that you purchased an electric shaver in the US, and thus you require the US socket type. You are now traveling in Germany, where another socket style is used. You will need a device, an adapter, that converts from the German to the US socket style. The functionality of adapters is actually natively provided by the `zope.interface` package and is thus well documented there. The `human.txt` file provides a gentle introduction to adapters, whereby `adapter.txt` is aimed at providing a comprehensive insight into adapters, but is too abstract for many as an initial read. Thus, we will only explain adapters in the context of the component architecture's API. So let's say that we have a German socket >>> from zope.interface import Interface, implements >>> class IGermanSocket(Interface): ... pass >>> class Socket(object): ... def __repr__(self): ... return '' %self.__class__.__name__ >>> class GermanSocket(Socket): ... """German wall socket.""" ... implements(IGermanSocket) and we want to convert it to an US socket >>> class IUSSocket(Interface): ... pass so that our shaver can be used in Germany. So we go to a German electronics store to look for an adapter that we can plug in the wall: >>> class GermanToUSSocketAdapter(Socket): ... implements(IUSSocket) ... __used_for__ = IGermanSocket ... ... def __init__(self, socket): ... self.context = socket Note that I could have called the passed in socket any way I like, but `context` is the standard name accepted. Single Adapters ~~~~~~~~~~~~~~~ Before we can use the adapter, we have to buy it and make it part of our inventory. In the component architecture we do this by registering the adapter with the framework, more specifically with the global site manager: >>> import zope.component >>> gsm = zope.component.getGlobalSiteManager() >>> gsm.registerAdapter(GermanToUSSocketAdapter, (IGermanSocket,), IUSSocket) `zope.component` is the component architecture API that is being presented by this file. You registered an adapter from `IGermanSocket` to `IUSSocket` having no name (thus the empty string). Anyways, you finally get back to your hotel room and shave, since you have not been able to shave in the plane. In the bathroom you discover a socket: >>> bathroomDE = GermanSocket() >>> IGermanSocket.providedBy(bathroomDE) True You now insert the adapter in the German socket >>> bathroomUS = zope.component.getAdapter(bathroomDE, IUSSocket, '') so that the socket now provides the US version: >>> IUSSocket.providedBy(bathroomUS) True Now you can insert your shaver and get on with your day. After a week you travel for a couple of days to the Prague and you notice that the Czech have yet another socket type: >>> class ICzechSocket(Interface): ... pass >>> class CzechSocket(Socket): ... implements(ICzechSocket) >>> czech = CzechSocket() You try to find an adapter for your shaver in your bag, but you fail, since you do not have one: >>> zope.component.getAdapter(czech, IUSSocket, '') \ ... #doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: (, , '') or the more graceful way: >>> marker = object() >>> socket = zope.component.queryAdapter(czech, IUSSocket, '', marker) >>> socket is marker True In the component architecture API any `get*` method will fail with a specific exception, if a query failed, whereby methods starting with `query*` will always return a `default` value after a failure. Named Adapters ~~~~~~~~~~~~~~ You are finally back in Germany. You also brought your DVD player and a couple DVDs with you, which you would like to watch. Your shaver was able to convert automatically from 110 volts to 240 volts, but your DVD player cannot. So you have to buy another adapter that also handles converting the voltage and the frequency of the AC current: >>> class GermanToUSSocketAdapterAndTransformer(object): ... implements(IUSSocket) ... __used_for__ = IGermanSocket ... ... def __init__(self, socket): ... self.context = socket Now, we need a way to keep the two adapters apart. Thus we register them with a name: >>> gsm.registerAdapter(GermanToUSSocketAdapter, ... (IGermanSocket,), IUSSocket, 'shaver',) >>> gsm.registerAdapter(GermanToUSSocketAdapterAndTransformer, ... (IGermanSocket,), IUSSocket, 'dvd') Now we simply look up the adapters using their labels (called *name*): >>> socket = zope.component.getAdapter(bathroomDE, IUSSocket, 'shaver') >>> socket.__class__ is GermanToUSSocketAdapter True >>> socket = zope.component.getAdapter(bathroomDE, IUSSocket, 'dvd') >>> socket.__class__ is GermanToUSSocketAdapterAndTransformer True Clearly, we do not have an adapter for the MP3 player >>> zope.component.getAdapter(bathroomDE, IUSSocket, 'mp3') \ ... #doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: (, , 'mp3') but you could use the 'dvd' adapter in this case of course. ;) Sometimes you want to know all adapters that are available. Let's say you want to know about all the adapters that convert a German to a US socket type: >>> sockets = list(zope.component.getAdapters((bathroomDE,), IUSSocket)) >>> len(sockets) 3 >>> names = [name for name, socket in sockets] >>> names.sort() >>> names [u'', u'dvd', u'shaver'] `zope.component.getAdapters()` returns a list of tuples. The first entry of the tuple is the name of the adapter and the second is the adapter itself. Multi-Adapters ~~~~~~~~~~~~~~ After watching all the DVDs you brought at least twice, you get tired of them and you want to listen to some music using your MP3 player. But darn, the MP3 player plug has a ground pin and all the adapters you have do not support that: >>> class IUSGroundedSocket(IUSSocket): ... pass So you go out another time to buy an adapter. This time, however, you do not buy yet another adapter, but a piece that provides the grounding plug: >>> class IGrounder(Interface): ... pass >>> class Grounder(object): ... implements(IGrounder) ... def __repr__(self): ... return '' Then together they will provided a grounded us socket: >>> class GroundedGermanToUSSocketAdapter(object): ... implements(IUSGroundedSocket) ... __used_for__ = (IGermanSocket, IGrounder) ... def __init__(self, socket, grounder): ... self.socket, self.grounder = socket, grounder You now register the combination, so that you know you can create a `IUSGroundedSocket`: >>> gsm.registerAdapter(GroundedGermanToUSSocketAdapter, ... (IGermanSocket, IGrounder), IUSGroundedSocket, 'mp3') Given the grounder >>> grounder = Grounder() and a German socket >>> livingroom = GermanSocket() we can now get a grounded US socket: >>> socket = zope.component.getMultiAdapter((livingroom, grounder), ... IUSGroundedSocket, 'mp3') >>> socket.__class__ is GroundedGermanToUSSocketAdapter True >>> socket.socket is livingroom True >>> socket.grounder is grounder True Of course, you do not have a 'dvd' grounded US socket available: >>> zope.component.getMultiAdapter((livingroom, grounder), ... IUSGroundedSocket, 'dvd') \ ... #doctest: +NORMALIZE_WHITESPACE Traceback (most recent call last): ... ComponentLookupError: ((, ), , 'dvd') >>> socket = zope.component.queryMultiAdapter( ... (livingroom, grounder), IUSGroundedSocket, 'dvd', marker) >>> socket is marker True Again, you might want to read `adapter.txt` in `zope.interface` for a more comprehensive coverage of multi-adapters. Subscribers ----------- While subscribers are directly supported by the adapter registry and are adapters for all theoretical purposes, practically it might be better to think of them as separate components. Subscribers are particularly useful for events. Let's say one of our adapters overheated and caused a small fire: >>> class IFire(Interface): ... pass >>> class Fire(object): ... implements(IFire) >>> fire = Fire() We want to use all available objects to put out the fire: >>> class IFireExtinguisher(Interface): ... def extinguish(): ... pass >>> class FireExtinguisher(object): ... def __init__(self, fire): ... pass ... def extinguish(self): ... "Place extinguish code here." ... print 'Used ' + self.__class__.__name__ + '.' Here some specific methods to put out the fire: >>> class PowderExtinguisher(FireExtinguisher): ... pass >>> gsm.registerSubscriptionAdapter(PowderExtinguisher, ... (IFire,), IFireExtinguisher) >>> class Blanket(FireExtinguisher): ... pass >>> gsm.registerSubscriptionAdapter(Blanket, (IFire,), IFireExtinguisher) >>> class SprinklerSystem(FireExtinguisher): ... pass >>> gsm.registerSubscriptionAdapter(SprinklerSystem, ... (IFire,), IFireExtinguisher) Now let use all these things to put out the fire: >>> extinguishers = zope.component.subscribers((fire,), IFireExtinguisher) >>> extinguishers.sort() >>> for extinguisher in extinguishers: ... extinguisher.extinguish() Used Blanket. Used PowderExtinguisher. Used SprinklerSystem. If no subscribers are found for a particular object, then an empty list is returned: >>> zope.component.subscribers((object(),), IFireExtinguisher) [] Utilities --------- Utilities are the second type of component, the component architecture implements. *Utilities* are simply components that provide an interface. When you register an utility, you always register an instance (in contrast to a factory for adapters) since the initialization and setup process of a utility might be complex and is not well defined. In some ways a utility is much more fundamental than an adapter, because an adapter cannot be used without another component, but a utility is always self-contained. I like to think of utilities as the foundation of your application and adapters as components extending beyond this foundation. Back to our story... After your vacation is over you fly back home to Tampa, Florida. But it is August now, the middle of the Hurricane season. And, believe it or not, you are worried that you will not be able to shave when the power goes out for several days. (You just hate wet shavers.) So you decide to go to your favorite hardware store and by a Diesel-powered electric generator. The generator provides of course a US-style socket: >>> class Generator(object): ... implements(IUSSocket) ... def __repr__(self): ... return '' >>> generator = Generator() Like for adapters, we now have to add the newly-acquired generator to our inventory by registering it as a utility: >>> gsm.registerUtility(generator, IUSSocket) We can now get the utility using >>> utility = zope.component.getUtility(IUSSocket) >>> utility is generator True As you can see, it is very simple to register and retrieve utilities. If a utility does not exist for a particular interface, such as the German socket, then the lookup fails >>> zope.component.getUtility(IGermanSocket) Traceback (most recent call last): ... ComponentLookupError: (, '') or more gracefully when specifying a default value: >>> default = object() >>> utility = zope.component.queryUtility(IGermanSocket, default=default) >>> utility is default True Note: The only difference between `getUtility()` and `queryUtility()` is the fact that you can specify a default value for the latter function, so that it will never cause a `ComponentLookupError`. Named Utilities ~~~~~~~~~~~~~~~ It is often desirable to have several utilities providing the same interface per site. This way you can implement any sort of registry using utilities. For this reason, utilities -- like adapters -- can be named. In the context of our story, we might want to do the following: You really do not trust gas stations either. What if the roads are blocked after a hurricane and the gas stations run out of oil. So you look for another renewable power source. Then you think about solar panels! After a storm there is usually very nice weather, so why not? Via the Web you order a set of 110V/120W solar panels that provide a regular US-style socket as output: >>> class SolarPanel(object): ... implements(IUSSocket) ... def __repr__(self): ... return '' >>> panel = SolarPanel() Once it arrives, we add it to our inventory: >>> gsm.registerUtility(panel, IUSSocket, 'Solar Panel') You can now access the solar panel using >>> utility = zope.component.getUtility(IUSSocket, 'Solar Panel') >>> utility is panel True Of course, if a utility is not available, then the lookup will simply fail >>> zope.component.getUtility(IUSSocket, 'Wind Mill') Traceback (most recent call last): ... ComponentLookupError: (, 'Wind Mill') or more gracefully when specifying a default value: >>> default = object() >>> utility = zope.component.queryUtility(IUSSocket, 'Wind Mill', ... default=default) >>> utility is default True Now you want to look at all the utilities you have for a particular kind. The following API function will return a list of name/utility pairs: >>> utils = list(zope.component.getUtilitiesFor(IUSSocket)) >>> utils.sort() >>> utils #doctest: +NORMALIZE_WHITESPACE [(u'', ), (u'Solar Panel', )] Another method of looking up all utilities is by using `getAllUtilitiesRegisteredFor(iface)`. This function will return an iterable of utilities (without names); however, it will also return overridden utilities. If you are not using multiple site managers, you will not actually need this method. >>> utils = list(zope.component.getAllUtilitiesRegisteredFor(IUSSocket)) >>> utils.sort() >>> utils [, ] Factories ~~~~~~~~~ A *factory* is a special kind of utility that exists to create other components. A factory is always identified by a name. It also provides a title and description and is able to tell the developer what interfaces the created object will provide. The advantage of using a factory to create an object instead of directly instantiating a class or executing any other callable is that we can refer to the factory by name. As long as the name stays fixed, the implementation of the callable can be renamed or moved without a breakage in code. Let's say that our solar panel comes in parts and they have to be assembled. This assembly would be done by a factory, so let's create one for the solar panel. To do this, we can use a standard implementation of the `IFactory` interface: >>> from zope.component.factory import Factory >>> factory = Factory(SolarPanel, ... 'Solar Panel', ... 'This factory creates a solar panel.') Optionally, I could have also specified the interfaces that the created object will provide, but the factory class is smart enough to determine the implemented interface from the class. We now register the factory: >>> from zope.component.interfaces import IFactory >>> gsm.registerUtility(factory, IFactory, 'SolarPanel') We can now get a list of interfaces the produced object will provide: >>> ifaces = zope.component.getFactoryInterfaces('SolarPanel') >>> IUSSocket in ifaces True By the way, this is equivalent to >>> ifaces2 = factory.getInterfaces() >>> ifaces is ifaces2 True Of course you can also just create an object: >>> panel = zope.component.createObject('SolarPanel') >>> panel.__class__ is SolarPanel True Note: Ignore the first argument (`None`) for now; it is the context of the utility lookup, which is usually an optional argument, but cannot be in this case, since all other arguments beside the `name` are passed in as arguments to the specified callable. Once you register several factories >>> gsm.registerUtility(Factory(Generator), IFactory, 'Generator') you can also determine, which available factories will create objects providing a certain interface: >>> factories = zope.component.getFactoriesFor(IUSSocket) >>> factories = [(name, factory.__class__) for name, factory in factories] >>> factories.sort() >>> factories #doctest: +NORMALIZE_WHITESPACE [(u'Generator', ), (u'SolarPanel', )] Site Managers ------------- Why do we need site managers? Why is the component architecture API not sufficient? Some applications, including Zope 3, have a concept of locations. It is often desirable to have different configurations for these location; this can be done by overwriting existing or adding new component registrations. Site managers in locations below the root location, should be able to delegate requests to their parent locations. The root site manager is commonly known as *global site manager*, since it is always available. You can always get the global site manager using the API: >>> gsm = zope.component.getGlobalSiteManager() >>> from zope.component import globalSiteManager >>> gsm is globalSiteManager True >>> from zope.component.interfaces import IComponentLookup >>> IComponentLookup.providedBy(gsm) True >>> from zope.component.interfaces import IComponents >>> IComponents.providedBy(gsm) True You can also lookup at site manager in a given context. The only requirement is that the context can be adapted to a site manager. So let's create a special site manager: >>> from zope.component.globalregistry import BaseGlobalComponents >>> sm = BaseGlobalComponents() Now we create a context that adapts to the site manager via the `__conform__` method as specified in PEP 246. >>> class Context(object): ... def __init__(self, sm): ... self.sm = sm ... def __conform__(self, interface): ... if interface.isOrExtends(IComponentLookup): ... return self.sm We now instantiate the `Context` with our special site manager: >>> context = Context(sm) >>> context.sm is sm True We can now ask for the site manager of this context: >>> lsm = zope.component.getSiteManager(context) >>> lsm is sm True The site manager instance `lsm` is formally known as a *local site manager* of `context`. CHANGES ******* 3.9.5 (2010-07-09) ================== - Fix test requirements specification. 3.9.4 (2010-04-30) ================== - Prefer the standard libraries doctest module to the one from zope.testing. 3.9.3 (2010-03-08) ================== - The ZCML directives provided by zope.component now register the components in the registry returned by getSiteManager instead of the global registry. This allows the hooking of the getSiteManager method before the load of a ZCML file to register the components in a custom registry. 3.9.2 (2010-01-22) ================== - Fixed a bug introduced by recent refactoring, where passing CheckerPublic to securityAdapterFactory wrongly wrapped the factory into a LocatingUntrustedAdapterFactory. 3.9.1 (2010-01-21) ================== - The tested testrunner somehow gets influenced by options of the outer testrunner, such a the -v option. We modified the tests so that it avoids this. 3.9.0 (2010-01-21) ================== - Add testlayer support. It is now possible to load a ZCML file within tests more easily. See zope.component.testlayer.py and zope.component.testlayer.txt. 3.8.0 (2009-11-16) ================== - Removed the dependencies on zope.proxy and zope.security from the zcml extra: zope.component does not hard depend on them anymore; the support for security proxied components ZCML registrations is enabled only if zope.security and zope.proxy are available. - Moved the IPossibleSite and ISite interfaces here from zope.location as they are dealing with zope.component's concept of a site, but not with location. - Moved the zope.site.hooks functionality to zope.component.hooks as it isn't actually dealing with zope.site's concept of a site. 3.7.1 (2009-07-24) ================== - Fixed a problem, where ``queryNextUtility`` could fail if the context could not be adapted to a ``IComponentLookup``. - Fixed 2 related bugs: When a utility is registered and there was previously a utility registered for the same interface and name, then the old utility is unregistered. The 2 bugs related to this: - There was no ``Unregistered`` for the implicit unregistration. Now there is. - The old utility was still held and returned by getAllUtilitiesRegisteredFor. In other words, it was still considered registered, eeven though it wasn't. A particularly negative consequence of this is that the utility is held in memory or in the database even though it isn't used. 3.7.0 (2009-05-21) ================== - The HookableTests were not run by the testrunner. - Add in zope:view and zope:resource implementations into zope.component.zcml (dependency loaded with zope.component [zcml]). 3.6.0 (2009-03-12) ================== - IMPORTANT: the interfaces that were defined in the zope.component.bbb.interfaces and deprecated for years are now (re)moved. However, some packages, including part of zope framework were still using those interfaces. They will be adapted for this change. If you were using some of those interfaces, you need to adapt your code as well: - The IView and IDefaultViewName were moved to zope.publisher.interfaces. - The IResource was moved to zope.app.publisher.interfaces. - IContextDependent, IPresentation, IPresentationRequest, IResourceFactory, IViewFactory were removed completely. If you used IViewFactory in context of zope.app.form, there's now IWidgetFactory in the zope.app.form.interfaces instead. - Add getNextUtility/queryNextUtility functions that used to be in zope.site earlier (and in zope.app.component even more earlier). - Added a pure-Python 'hookable' implementation, for use when 'zope.hookable' is not present. - Removed use of 'zope.deferredimport' by breaking import cycles. - Cleanup package documentation and changelog a bit. Add sphinx-based documentation building command to the buildout. - Remove deprecated code. - Change package's mailing list address to zope-dev at zope.org, because zope3-dev at zope.org is now retired. 3.5.1 (2008-07-25) ================== - Fix bug introduced in 3.5.0: no longer supported interfaces declared in Python and always wanted an explicit provides="..." attribute. https://bugs.launchpad.net/zope3/+bug/251865 3.5.0 (2008-07-25) ================== - Support registration of utilities via factories through the component registry and return factory information in the registration information. This fixes https://bugs.launchpad.net/zope3/+bug/240631 - Optimized un/registerUtility via storing an optimized data structure for efficient retrieval of already registered utilities. This avoids looping over all utilities when registering a new one. 3.4.0 (2007-09-29) ================== No further changes since 3.4.0a1. 3.4.0a1 (2007-04-22) ==================== Corresponds to zope.component from Zope 3.4.0a1. - In the Zope 3.3.x series, ``zope.component`` was simplified yet once more. See http://wiki.zope.org/zope3/LocalComponentManagementSimplification for the proposal describing the changes. 3.2.0.2 (2006-04-15) ==================== - Fix packaging bug: 'package_dir' must be a *relative* path. 3.2.0.1 (2006-04-14) ==================== - Packaging change: suppress inclusion of 'setup.cfg' in 'sdist' builds. 3.2.0 (2006-01-05) ================== Corresponds to the verison of the zope.component package shipped as part of the Zope 3.2.0 release. - Deprecated services and related APIs. The adapter and utility registries are now available directly via the site manager's 'adapters' and 'utilities' attributes, respectively. Services are accessible, but deprecated, and will be removed in Zope 3.3. - Deprectaed all presentation-related APIs, including all view-related API functions. Use the adapter API functions instead.

We'd like to be able to change the template used by a form without being forced to modify the form. Named templates provide templates that are registered as named view adapters. To define a named template, use the `NamedTemplateImplementation` constructor: >>> from zope.browserpage import ViewPageTemplateFile >>> from zope.browserpage.namedtemplate import ( ... NamedTemplateImplementation) >>> sample = ViewPageTemplateFile('tests/namedtemplate.pt') >>> sample = NamedTemplateImplementation(sample) Let's define a view that uses the named template. To use a named template, use the NamedTemplate constructor, and give a template name: >>> from zope.browserpage.namedtemplate import NamedTemplate >>> class MyView: ... def __init__(self, context, request): ... self.context = context ... self.request = request ... ... __call__ = NamedTemplate('sample') Normally, we'd register a named template for a view interface, to allow it to be registered for multiple views. We'll just register it for our view class. >>> from zope import component >>> component.provideAdapter(sample, [MyView], name='sample') Now, with this in place, we should be able to use our view: >>> class MyContent: ... def __init__(self, name): ... self.name = name >>> from zope.publisher.browser import TestRequest >>> print MyView(MyContent('bob'), TestRequest())(x=42) Hello bob The URL is http://127.0.0.1 The positional arguments were () The keyword argument x is 42 The view type that a named template is to be used for can be supplied when the named template is created: >>> class MyView: ... def __init__(self, context, request): ... self.context = context ... self.request = request ... ... __call__ = NamedTemplate('sample2') >>> sample = ViewPageTemplateFile('tests/namedtemplate.pt') >>> sample = NamedTemplateImplementation(sample, MyView) >>> component.provideAdapter(sample, name='sample2') >>> print MyView(MyContent('bob'), TestRequest())(x=42) Hello bob The URL is http://127.0.0.1 The positional arguments were () The keyword argument x is 42 zope2.13-2.13.21/source/zope.browserpage/src/zope/browserpage/metaconfigure.py0000644000175000017500000003573112214017535026232 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

Home-page: http://pypi.python.org/pypi/zope.browserpage/ Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: ======== Overview ======== *This package is at present not reusable without depending on a large chunk of the Zope Toolkit and its assumptions. It is maintained by the* `Zope Toolkit project `_. This package provides ZCML directives for configuring browser views. More specifically it defines the following ZCML directives: * browser:page * browser:pages * browser:view These directives also support menu item registration for pages, when ``zope.browsermenu`` package is installed. Otherwise, they simply ignore the menu attribute. ======= CHANGES ======= 3.12.2 (2010-05-24) =================== - Fixed unit tests broken under Python 2.4 by the switch to the standard library ``doctest`` module. 3.12.1 (2010-04-30) =================== - Prefer the standard library's ``doctest`` module to the one from ``zope.testing``. 3.12.0 (2010-04-26) =================== - Move the implementation of ``tales:expressiontype`` here from ``zope.app.pagetemplate``. 3.11.0 (2009-12-22) =================== - Move the named template implementation here from ``zope.app.pagetemplate``. 3.10.1 (2009-12-22) =================== - Depend on the ``untrustedpython`` extra of ``zope.security``, since we import from ``zope.pagetemplate.engine``. 3.10.0 (2009-12-22) =================== - Remove the dependency on ``zope.app.pagetemplate`` by moving ``viewpagetemplatefile``, ``simpleviewclass`` and ``metaconfigure.registerType`` into this package. 3.9.0 (2009-08-27) ================== - Initial release. This package was split off from ``zope.app.publisher``.

ZConfig 2.9.0 (2011-03-22) -------------------------- - Allow identical redefinition of ``%define`` names. - Added support for IPv6 addresses. ZConfig 2.8.0 (2010-04-13) -------------------------- - Fix relative path recognition. https://bugs.launchpad.net/zconfig/+bug/405687 - Added SMTP authentication support for email logger on Python 2.6. ZConfig 2.7.1 (2009-06-13) -------------------------- - Improved documentation - Fixed tests failures on windows. ZConfig 2.7.0 (2009-06-11) -------------------------- - Added a convenience function, ``ZConfig.configureLoggers(text)`` for configuring loggers. - Relaxed the requirement for a logger name in logger sections, allowing the logger section to be used for both root and non-root loggers. ZConfig 2.6.1 (2008-12-05) -------------------------- - Fixed support for schema descriptions that override descriptions from a base schema. If multiple base schema provide descriptions but the derived schema does not, the first base mentioned that provides a description wins. https://bugs.launchpad.net/zconfig/+bug/259475 - Fixed compatibility bug with Python 2.5.0. - No longer trigger deprecation warnings under Python 2.6. ZConfig 2.6.0 (2008-09-03) -------------------------- - Added support for file rotation by time by specifying when and interval, rather than max-size, for log files. - Removed dependency on setuptools from the setup.py. ZConfig 2.5.1 (2007-12-24) -------------------------- - Made it possible to run unit tests via 'python setup.py test' (requires setuptools on sys.path). - Added better error messages to test failure assertions. ZConfig 2.5 (2007-08-31) ------------------------ *A note on the version number:* Information discovered in the revision control system suggests that some past revision has been called "2.4", though it is not clear that any actual release was made with that version number. We're going to skip revision 2.4 entirely to avoid potential issues with anyone using something claiming to be ZConfig 2.4, and go straight to version 2.5. - Add support for importing schema components from ZIP archives (including eggs). - Added a 'formatter' configuration option in the logging handler sections to allow specifying a constructor for the formatter. - Documented the package: URL scheme that can be used in extending schema. - Added support for reopening all log files opened via configurations using the ZConfig.components.logger package. For Zope, this is usable via the ``zc.signalhandler`` package. ``zc.signalhandler`` is not required for ZConfig. - Added support for rotating log files internally by size. - Added a minimal implementation of schema-less parsing; this is mostly intended for applications that want to read several fragments of ZConfig configuration files and assemble a combined configuration. Used in some ``zc.buildout`` recipes. - Converted to using ``zc.buildout`` and the standard test runner from ``zope.testing``. - Added more tests. ZConfig 2.3.1 (2005-08-21) -------------------------- - Isolated some of the case-normalization code so it will at least be easier to override. This remains non-trivial. ZConfig 2.3 (2005-05-18) ------------------------ - Added "inet-binding-address" and "inet-connection-address" to the set of standard datatypes. These are similar to the "inet-address" type, but the default hostname is more sensible. The datatype used should reflect how the value will be used. - Alternate rotating logfile handler for Windows, to avoid platform limitations on renaming open files. Contributed by Sidnei da Silva. - For
and , if the name attribute is omitted, assume name="*", since this is what is used most often. ZConfig 2.2 (2004-04-21) ------------------------ - More documentation has been written. - Added a timedelta datatype function; the input is the same as for the time-interval datatype, but the resulting value is a datetime.timedelta object. - Make sure keys specified as attributes of the element are converted by the appropriate key type, and are re-checked for derived sections. - Refactored the ZConfig.components.logger schema components so that a schema can import just one of the "eventlog" or "logger" sections if desired. This can be helpful to avoid naming conflicts. - Added a reopen() method to the logger factories. - Always use an absolute pathname when opening a FileHandler. - A fix to the logger 'format' key to allow the %(process)d expansion variable that the logging package supports. - A new timedelta built-in datatype was added. Similar to time-interval except that it returns a datetime.timedelta object instead. ZConfig 2.1 (2004-04-12) ------------------------ - Removed compatibility with Python 2.1 and 2.2. - Schema components must really be in Python packages; the directory search has been modified to perform an import to locate the package rather than incorrectly implementing the search algorithm. - The default objects use for section values now provide a method getSectionAttributes(); this returns a list of all the attributes of the section object which store configuration-defined data (including information derived from the schema). - Default information can now be included in a schema for and by using . - More documentation has been added to discuss schema extension. - Support for a Unicode-free Python has been fixed. - Derived section types now inherit the datatype of the base type if no datatype is identified explicitly. - Derived section types can now override the keytype instead of always inheriting from their base type. - makes use of the current prefix if the package name begins witha dot. - Added two standard datatypes: dotted-name and dotted-suffix. - Added two standard schema components: ZConfig.components.basic and ZConfig.components.logger. ZConfig 2.0 (2003-10-27) ------------------------ - Configurations can import additional schema components using a new "%import" directive; this can be used to integrate 3rd-party components into an application. - Schemas may be extended using a new "extends" attribute on the element. - Better error messages when elements in a schema definition are improperly nested. - The "zconfig" script can now simply verify that a schema definition is valid, if that's all that's needed.

It supports a hierarchical schema-driven configuration model that allows a schema to specify data conversion routines written in Python. ZConfig's model is very different from the model supported by the ConfigParser module found in Python's standard library, and is more suitable to configuration-intensive applications. ZConfig schema are written in an XML-based language and are able to "import" schema components provided by Python packages. Since components are able to bind to conversion functions provided by Python code in the package (or elsewhere), configuration objects can be arbitrarily complex, with values that have been verified against arbitrary constraints. This makes it easy for applications to separate configuration support from configuration loading even with configuration data being defined and consumed by a wide range of separate packages. ZConfig is licensed under the Zope Public License, version 2.1. See the file LICENSE.txt in the distribution for the full license text. Reference documentation is available in the doc/ directory. One common use of ZConfig is to configure the Python logging framework. This is extremely simple to do as the following example demonstrates: >>> from ZConfig import configureLoggers >>> configureLoggers(''' ... ... level INFO ... ... PATH STDOUT ... format %(levelname)s %(name)s %(message)s ... ... ... ''') The above configures the root logger to output messages logged at INFO or above to the console, as we can see in the following example: >>> from logging import getLogger >>> logger = getLogger() >>> logger.info('An info message') INFO root An info message >>> logger.debug('A debug message') A more common configuration would see STDOUT replaced with a path to the file into which log entries would be written. For more information, see section 5.2 on the ZConfig documentation and the examples in ZConfig/components/logger/tests. Information on the latest released version of the ZConfig package is available at http://www.zope.org/Members/fdrake/zconfig/ You may either create an RPM and install this, or install directly from the source distribution. There is a mailing list for discussions and questions about ZConfig; more information on the list is available at http://mail.zope.org/mailman/listinfo/zconfig/ Installing from the source distribution --------------------------------------- For a simple installation:: python setup.py install To install to a user's home-dir:: python setup.py install --home= To install to another prefix (for example, /usr/local):: python setup.py install --prefix=/usr/local If you need to force the python interpreter to (for example) python2:: python2 setup.py install For more information on installing packages, please refer to `Installing Python Modules `__. ========================== Change History for ZConfig ========================== ZConfig 2.9.1 (2012-02-11) -------------------------- - Make FileHandler.reopen thread safe.

It supports a hierarchical schema-driven configuration model that allows a schema to specify data conversion routines written in Python. ZConfig's model is very different from the model supported by the ConfigParser module found in Python's standard library, and is more suitable to configuration-intensive applications. ZConfig schema are written in an XML-based language and are able to "import" schema components provided by Python packages. Since components are able to bind to conversion functions provided by Python code in the package (or elsewhere), configuration objects can be arbitrarily complex, with values that have been verified against arbitrary constraints. This makes it easy for applications to separate configuration support from configuration loading even with configuration data being defined and consumed by a wide range of separate packages. ZConfig is licensed under the Zope Public License, version 2.1. See the file LICENSE.txt in the distribution for the full license text. Reference documentation is available in the doc/ directory. One common use of ZConfig is to configure the Python logging framework. This is extremely simple to do as the following example demonstrates: >>> from ZConfig import configureLoggers >>> configureLoggers(''' ... ... level INFO ... ... PATH STDOUT ... format %(levelname)s %(name)s %(message)s ... ... ... ''') The above configures the root logger to output messages logged at INFO or above to the console, as we can see in the following example: >>> from logging import getLogger >>> logger = getLogger() >>> logger.info('An info message') INFO root An info message >>> logger.debug('A debug message') A more common configuration would see STDOUT replaced with a path to the file into which log entries would be written. For more information, see section 5.2 on the ZConfig documentation and the examples in ZConfig/components/logger/tests. Information on the latest released version of the ZConfig package is available at http://www.zope.org/Members/fdrake/zconfig/ You may either create an RPM and install this, or install directly from the source distribution. There is a mailing list for discussions and questions about ZConfig; more information on the list is available at http://mail.zope.org/mailman/listinfo/zconfig/ Installing from the source distribution --------------------------------------- For a simple installation:: python setup.py install To install to a user's home-dir:: python setup.py install --home= To install to another prefix (for example, /usr/local):: python setup.py install --prefix=/usr/local If you need to force the python interpreter to (for example) python2:: python2 setup.py install For more information on installing packages, please refer to `Installing Python Modules `__. ========================== Change History for ZConfig ========================== ZConfig 2.9.1 (2012-02-11) -------------------------- - Make FileHandler.reopen thread safe. ZConfig 2.9.0 (2011-03-22) -------------------------- - Allow identical redefinition of ``%define`` names. - Added support for IPv6 addresses. ZConfig 2.8.0 (2010-04-13) -------------------------- - Fix relative path recognition. https://bugs.launchpad.net/zconfig/+bug/405687 - Added SMTP authentication support for email logger on Python 2.6. ZConfig 2.7.1 (2009-06-13) -------------------------- - Improved documentation - Fixed tests failures on windows. ZConfig 2.7.0 (2009-06-11) -------------------------- - Added a convenience function, ``ZConfig.configureLoggers(text)`` for configuring loggers. - Relaxed the requirement for a logger name in logger sections, allowing the logger section to be used for both root and non-root loggers. ZConfig 2.6.1 (2008-12-05) -------------------------- - Fixed support for schema descriptions that override descriptions from a base schema. If multiple base schema provide descriptions but the derived schema does not, the first base mentioned that provides a description wins. https://bugs.launchpad.net/zconfig/+bug/259475 - Fixed compatibility bug with Python 2.5.0. - No longer trigger deprecation warnings under Python 2.6. ZConfig 2.6.0 (2008-09-03) -------------------------- - Added support for file rotation by time by specifying when and interval, rather than max-size, for log files. - Removed dependency on setuptools from the setup.py. ZConfig 2.5.1 (2007-12-24) -------------------------- - Made it possible to run unit tests via 'python setup.py test' (requires setuptools on sys.path). - Added better error messages to test failure assertions. ZConfig 2.5 (2007-08-31) ------------------------ *A note on the version number:* Information discovered in the revision control system suggests that some past revision has been called "2.4", though it is not clear that any actual release was made with that version number. We're going to skip revision 2.4 entirely to avoid potential issues with anyone using something claiming to be ZConfig 2.4, and go straight to version 2.5. - Add support for importing schema components from ZIP archives (including eggs). - Added a 'formatter' configuration option in the logging handler sections to allow specifying a constructor for the formatter. - Documented the package: URL scheme that can be used in extending schema. - Added support for reopening all log files opened via configurations using the ZConfig.components.logger package. For Zope, this is usable via the ``zc.signalhandler`` package. ``zc.signalhandler`` is not required for ZConfig. - Added support for rotating log files internally by size. - Added a minimal implementation of schema-less parsing; this is mostly intended for applications that want to read several fragments of ZConfig configuration files and assemble a combined configuration. Used in some ``zc.buildout`` recipes. - Converted to using ``zc.buildout`` and the standard test runner from ``zope.testing``. - Added more tests. ZConfig 2.3.1 (2005-08-21) -------------------------- - Isolated some of the case-normalization code so it will at least be easier to override. This remains non-trivial. ZConfig 2.3 (2005-05-18) ------------------------ - Added "inet-binding-address" and "inet-connection-address" to the set of standard datatypes. These are similar to the "inet-address" type, but the default hostname is more sensible. The datatype used should reflect how the value will be used. - Alternate rotating logfile handler for Windows, to avoid platform limitations on renaming open files. Contributed by Sidnei da Silva. - For
and , if the name attribute is omitted, assume name="*", since this is what is used most often. ZConfig 2.2 (2004-04-21) ------------------------ - More documentation has been written. - Added a timedelta datatype function; the input is the same as for the time-interval datatype, but the resulting value is a datetime.timedelta object. - Make sure keys specified as attributes of the element are converted by the appropriate key type, and are re-checked for derived sections. - Refactored the ZConfig.components.logger schema components so that a schema can import just one of the "eventlog" or "logger" sections if desired. This can be helpful to avoid naming conflicts. - Added a reopen() method to the logger factories. - Always use an absolute pathname when opening a FileHandler. - A fix to the logger 'format' key to allow the %(process)d expansion variable that the logging package supports. - A new timedelta built-in datatype was added. Similar to time-interval except that it returns a datetime.timedelta object instead. ZConfig 2.1 (2004-04-12) ------------------------ - Removed compatibility with Python 2.1 and 2.2. - Schema components must really be in Python packages; the directory search has been modified to perform an import to locate the package rather than incorrectly implementing the search algorithm. - The default objects use for section values now provide a method getSectionAttributes(); this returns a list of all the attributes of the section object which store configuration-defined data (including information derived from the schema). - Default information can now be included in a schema for and by using . - More documentation has been added to discuss schema extension. - Support for a Unicode-free Python has been fixed. - Derived section types now inherit the datatype of the base type if no datatype is identified explicitly. - Derived section types can now override the keytype instead of always inheriting from their base type. - makes use of the current prefix if the package name begins witha dot. - Added two standard datatypes: dotted-name and dotted-suffix. - Added two standard schema components: ZConfig.components.basic and ZConfig.components.logger. ZConfig 2.0 (2003-10-27) ------------------------ - Configurations can import additional schema components using a new "%import" directive; this can be used to integrate 3rd-party components into an application. - Schemas may be extended using a new "extends" attribute on the element. - Better error messages when elements in a schema definition are improperly nested. - The "zconfig" script can now simply verify that a schema definition is valid, if that's all that's needed.

ZConfig 1.0 (2003-03-25) ------------------------ - Initial release.

ZConfig is a configuration library intended for general use. It supports a hierarchical schema-driven configuration model that allows a schema to specify data conversion routines written in Python. ZConfig's model is very different from the model supported by the ConfigParser module found in Python's standard library, and is more suitable to configuration-intensive applications. ZConfig schema are written in an XML-based language and are able to ``import`` schema components provided by Python packages. Since components are able to bind to conversion functions provided by Python code in the package (or elsewhere), configuration objects can be arbitrarily complex, with values that have been verified against arbitrary constraints. This makes it easy for applications to separate configuration support from configuration loading even with configuration data being defined and consumed by a wide range of separate packages. $Id: __init__.py,v 1.18 2004/04/15 20:33:32 fdrake Exp $ """ __docformat__ = "reStructuredText" version_info = (2, 3) __version__ = ".".join([str(n) for n in version_info]) from ZConfig.loader import loadConfig, loadConfigFile from ZConfig.loader import loadSchema, loadSchemaFile class ConfigurationError(Exception): """Base class for ZConfig exceptions.""" # The 'message' attribute was deprecated for BaseException with # Python 2.6; here we create descriptor properties to continue using it def __set_message(self, v): self.__dict__['message'] = v def __get_message(self): return self.__dict__['message'] def __del_message(self): del self.__dict__['message'] message = property(__get_message, __set_message, __del_message) def __init__(self, msg, url=None): self.message = msg self.url = url Exception.__init__(self, msg) def __str__(self): return self.message class _ParseError(ConfigurationError): def __init__(self, msg, url, lineno, colno=None): self.lineno = lineno self.colno = colno ConfigurationError.__init__(self, msg, url) def __str__(self): s = self.message if self.url: s += "\n(" elif (self.lineno, self.colno) != (None, None): s += " (" if self.lineno: s += "line %d" % self.lineno if self.colno is not None: s += ", column %d" % self.colno if self.url: s += " in %s)" % self.url else: s += ")" elif self.url: s += self.url + ")" return s class SchemaError(_ParseError): """Raised when there's an error in the schema itself.""" def __init__(self, msg, url=None, lineno=None, colno=None): _ParseError.__init__(self, msg, url, lineno, colno) class SchemaResourceError(SchemaError): """Raised when there's an error locating a resource required by the schema.

This is most interesting when assembling a configuration from fragments, as some buildout recipes do. This is not recommended for general application use. The ``ZConfig.schemaless`` module provides some support for working without schema. Something things are not (currently) supported, including the %define and %include directives. The %import directive is supported. This module provides basic support for loading configuration, inspecting and modifying it, and re-serializing the result. >>> from ZConfig import schemaless There is a single function which loads configuration data from a file open for reading. Let's take a look at this, and what it returns:: >>> config_text = ''' ... ... some-key some-value ... ... some-key another-value ... ...
... key1 value1.1 ... key1 value1.2 ... key2 value2 ... ... ... another key ... another value ... ...
... ... another-key whee! ... ... ... ... nothing here ... ... ... ''' >>> import StringIO >>> config = schemaless.loadConfigFile(StringIO.StringIO(config_text)) The `config` object is a mapping from top-level keys to lists of values:: >>> config["some-key"] ['some-value', 'another-value'] >>> config["another-key"] ['whee!'] >>> config["no-such-key-in-the-config"] Traceback (most recent call last): KeyError: 'no-such-key-in-the-config' >>> lst = list(config) >>> lst.sort() >>> lst ['another-key', 'some-key'] There is also a ``sections`` attribute that lists child sections:: >>> len(config.sections) 2 Let's take a look at one of the sections. Like the top-level configuration, the section maps keys >>> section = config.sections[0] >>> section["key1"] ['value1.1', 'value1.2'] >>> section["key2"] ['value2'] >>> section["no-such-key-in-the-config"] Traceback (most recent call last): KeyError: 'no-such-key-in-the-config' >>> lst = list(section) >>> lst.sort() >>> lst ['key1', 'key2'] Child sections are again available via the ``sections`` attribute:: >>> len(section.sections) 1 In addition, the section has ``type`` and ``name`` attributes that record the type and name of the section as ZConfig understands them:: >>> section.type 'section' >>> print section.name None Let's look at the named section from our example, so we can see the name:: >>> section = config.sections[1] >>> section.type 'another' >>> section.name 'named' We can also mutate the configuration, adding new keys and values as desired:: >>> config["new-key"] = ["new-value-1", "new-value-2"] >>> config["some-key"].append("third-value") New sections can also be added:: >>> section = schemaless.Section("sectiontype", "my-name") >>> section["key"] = ["value"] >>> config.sections.insert(1, section) The configuration can be re-serialized using ``str()``:: >>> print str(config) another-key whee! new-key new-value-1 new-key new-value-2 some-key some-value some-key another-value some-key third-value
key1 value1.1 key1 value1.2 key2 value2 another key another value
key value nothing here Note that some adjustments have been made: - key/value pairs come before child sections - keys are sorted at each level - blank lines are removed, with new blank lines inserted to preserve some semblance of readability These are all presentation changes, but not essential changes to the configuration data. The ordering of sections is not modified in rendering, nor are the values for a single key re-ordered within a section or top-level configuration. Support for %import ------------------- Imports are supported, and are re-ordered in much the same way that other elements of a configuration are:: >>> config_text = ''' ... ... %import some.package ... ...
... ... %import another.package ... ... ... some value ... ... ...
... ... some-key some-value ... ... ''' >>> config = schemaless.loadConfigFile(StringIO.StringIO(config_text)) >>> print config %import some.package %import another.package some-key some-value
some value
The imports are also available as the ``imports`` attribute of the configuration object:: >>> config.imports ('some.package', 'another.package') Multiple imports of the same name are removed:: >>> config_text = ''' ... ... %import some.package ... %import another.package ... %import some.package ... ... ''' >>> config = schemaless.loadConfigFile(StringIO.StringIO(config_text)) >>> print config %import some.package %import another.package >>> config.imports ('some.package', 'another.package') Limitations ----------- There are some limitations of handling ZConfig-based configurations using the ``ZConfig.schemaless`` module. Some of these are implementation issues, and may be corrected in the future: - %define is not supported. - %include is not supported. Others are a function of not processing the schema, and can't easily be avoided: - normalization of keys based on keytypes specified in the or elements of the schema if not performed. If the transformation of a key might affect the behavior controlled by the resulting configuration, the generated configuration may not be equivalent. Examples of this are unusual, but exist. Limitations related to the non-processing of the schema cannot be detected by the ``ZConfig.schemaless``, so no errors are reported in these situations. For the strictly syntactic limitations, we do get errors when the input data requires they be supported. Let's look at both the %define and %include handling. When %define is used in the input configuration, an exception is raised when loading the configuration:: >>> config_text = ''' ... ... %define somename somevalue ... ... ''' >>> schemaless.loadConfigFile(StringIO.StringIO(config_text)) Traceback (most recent call last): NotImplementedError: defines are not supported A similar exception is raised for %include:: >>> config_text = ''' ... ... %include some/other/file.conf ... ... ''' >>> schemaless.loadConfigFile(StringIO.StringIO(config_text)) Traceback (most recent call last): NotImplementedError: includes are not supported zope2.13-2.13.21/source/ZConfig/ZConfig/components/0000755000175000017500000000000012214017462020521 5ustar arnauarnauzope2.13-2.13.21/source/ZConfig/ZConfig/components/basic/0000755000175000017500000000000012214017462021602 5ustar arnauarnauzope2.13-2.13.21/source/ZConfig/ZConfig/components/basic/mapping.py0000644000175000017500000000137412214017462023614 0ustar arnauarnau############################################################################## # # Copyright (c) 2003 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

It supports a hierarchical schema-driven configuration model that allows a schema to specify data conversion routines written in Python. ZConfig's model is very different from the model supported by the ConfigParser module found in Python's standard library, and is more suitable to configuration-intensive applications. ZConfig schema are written in an XML-based language and are able to "import" schema components provided by Python packages. Since components are able to bind to conversion functions provided by Python code in the package (or elsewhere), configuration objects can be arbitrarily complex, with values that have been verified against arbitrary constraints. This makes it easy for applications to separate configuration support from configuration loading even with configuration data being defined and consumed by a wide range of separate packages. ZConfig is licensed under the Zope Public License, version 2.1. See the file LICENSE.txt in the distribution for the full license text. Reference documentation is available in the doc/ directory. One common use of ZConfig is to configure the Python logging framework. This is extremely simple to do as the following example demonstrates: >>> from ZConfig import configureLoggers >>> configureLoggers(''' ... ... level INFO ... ... PATH STDOUT ... format %(levelname)s %(name)s %(message)s ... ... ... ''') The above configures the root logger to output messages logged at INFO or above to the console, as we can see in the following example: >>> from logging import getLogger >>> logger = getLogger() >>> logger.info('An info message') INFO root An info message >>> logger.debug('A debug message') A more common configuration would see STDOUT replaced with a path to the file into which log entries would be written. For more information, see section 5.2 on the ZConfig documentation and the examples in ZConfig/components/logger/tests. Information on the latest released version of the ZConfig package is available at http://www.zope.org/Members/fdrake/zconfig/ You may either create an RPM and install this, or install directly from the source distribution.

This configuration mechanism is itself configured using a schema specification written in XML. \end{abstract} \tableofcontents \section{Introduction \label{intro}} Zope uses a common syntax and API for configuration files designed for software components written by Zope Corporation. Third-party software which is also part of a Zope installation may use a different syntax, though any software is welcome to use the syntax used by Zope Corporation. Any software written in Python is free to use the \module{ZConfig} software to load such configuration files in order to ensure compatibility. This software is covered by the Zope Public License, version 2.1. The \module{ZConfig} package has been tested with Python 2.3. Older versions of Python are not supported. \module{ZConfig} only relies on the Python standard library. Configurations which use \module{ZConfig} are described using \dfn{schema}. A schema is a specification for the allowed structure and content of the configuration. \module{ZConfig} schema are written using a small XML-based language. The schema language allows the schema author to specify the names of the keys allowed at the top level and within sections, to define the types of sections which may be used (and where), the types of each values, whether a key or section must be specified or is optional, default values for keys, and whether a value can be given only once or repeatedly. \section{Configuration Syntax \label{syntax}} Like the \ulink{\module{ConfigParser}} {http://docs.python.org/library/configparser.html} format, this format supports key-value pairs arranged in sections. Unlike the \module{ConfigParser} format, sections are typed and can be organized hierarchically. Additional files may be included if needed. Schema components not specified in the application schema can be imported from the configuration file. Though both formats are substantially line-oriented, this format is more flexible. The intent of supporting nested section is to allow setting up the configurations for loosely-associated components in a container. For example, each process running on a host might get its configuration section from that host's section of a shared configuration file. The top level of a configuration file consists of a series of inclusions, key-value pairs, and sections. Comments can be added on lines by themselves. A comment has a \character{\#} as the first non-space character and extends to the end of the line: \begin{verbatim} # This is a comment \end{verbatim} An inclusion is expressed like this: \begin{verbatim} %include defaults.conf \end{verbatim} The resource to be included can be specified by a relative or absolute URL, resolved relative to the URL of the resource the \keyword{\%include} directive is located in. A key-value pair is expressed like this: \begin{verbatim} key value \end{verbatim} The key may include any non-white characters except for parentheses. The value contains all the characters between the key and the end of the line, with surrounding whitespace removed. Since comments must be on lines by themselves, the \character{\#} character can be part of a value: \begin{verbatim} key value # still part of the value \end{verbatim} Sections may be either empty or non-empty. An empty section may be used to provide an alias for another section. A non-empty section starts with a header, contains configuration data on subsequent lines, and ends with a terminator. The header for a non-empty section has this form (square brackets denote optional parts): \begin{alltt} <\var{section-type} \optional{\var{name}} > \end{alltt} \var{section-type} and \var{name} all have the same syntactic constraints as key names. The terminator looks like this: \begin{alltt} \end{alltt} The configuration data in a non-empty section consists of a sequence of one or more key-value pairs and sections. For example: \begin{verbatim} key-1 value-1 key-2 value-2 key-3 value-3 \end{verbatim} (The indentation is used here for clarity, but is not required for syntactic correctness.) The header for empty sections is similar to that of non-empty sections, but there is no terminator: \begin{alltt} <\var{section-type} \optional{\var{name}} /> \end{alltt} \subsection{Extending the Configuration Schema} As we'll see in section~\ref{writing-schema}, ``Writing Configuration Schema,'' what can be written in a configuration is controlled by schemas which can be built from \emph{components}. These components can also be used to extend the set of implementations of objects the application can handle. What this means when writing a configuration is that third-party implementations of application object types can be used wherever those application types are used in the configuration, if there's a \module{ZConfig} component available for that implementation. The configuration file can use an \keyword{\%import} directive to load a named component: \begin{verbatim} %import Products.Ape \end{verbatim} The text to the right of the \keyword{\%import} keyword must be the name of a Python package; the \module{ZConfig} component provided by that package will be loaded and incorporated into the schema being used to load the configuration file. After the import, section types defined in the component may be used in the configuration. More detail is needed for this to really make sense. A schema may define section types which are \emph{abstract}; these cannot be used directly in a configuration, but multiple concrete section types can be defined which \emph{implement} the abstract types. Wherever the application allows an abstract type to be used, any concrete type which implements that abstract type can be used in an actual configuration. The \keyword{\%import} directive allows loading schema components which provide alternate concrete section types which implement the abstract types defined by the application. This allows third-party implementations of abstract types to be used in place of or in addition to implementations provided with the application. Consider an example application application which supports logging in the same way Zope 2 does. There are some parameters which configure the general behavior of the logging mechanism, and an arbitrary number of \emph{log handlers} may be specified to control how the log messages are handled. Several log handlers are provided by the application. Here is an example logging configuration: \begin{verbatim} level verbose path /var/log/myapp/events.log \end{verbatim} A third-party component may provide a log handler to send high-priority alerts the system administrator's text pager or SMS-capable phone. All that's needed is to install the implementation so it can be imported by Python, and modify the configuration: \begin{verbatim} %import my.pager.loghandler level verbose path /var/log/myapp/events.log number 1-800-555-1234 message Something broke! \end{verbatim} \subsection{Textual Substitution in Values} \module{ZConfig} provides a limited way to re-use portions of a value using simple string substitution. To use this facility, define named bits of replacement text using the \keyword{\%define} directive, and reference these texts from values. The syntax for \keyword{\%define} is: \begin{alltt} %define \var{name} \optional{\var{value}} \end{alltt} The value of \var{name} must be a sequence of letters, digits, and underscores, and may not start with a digit; the namespace for these names is separate from the other namespaces used with \module{ZConfig}, and is case-insensitive. If \var{value} is omitted, it will be the empty string. If given, there must be whitespace between \var{name} and \var{value}; \var{value} will not include any whitespace on either side, just like values from key-value pairs. Names must be defined before they are used, and may not be re-defined with a different value. All resources being parsed as part of a configuration share a single namespace for defined names. References to defined names from configuration values use the syntax described for the \refmodule{ZConfig.substitution} module. Configuration values which include a \character{\$} as part of the actual value will need to use \code{\$\$} to get a single \character{\$} in the result. The values of defined names are processed in the same way as configuration values, and may contain references to named definitions. For example, the value for \code{key} will evaluate to \code{value}: \begin{verbatim} %define name value key $name \end{verbatim} %$ <-- bow to font-lock \section{Writing Configuration Schema \label{writing-schema}} \module{ZConfig} schema are written as XML documents. Data types are searched in a special namespace defined by the data type registry. The default registry has slightly magical semantics: If the value can be matched to a standard data type when interpreted as a \datatype{basic-key}, the standard data type will be used. If that fails, the value must be a \datatype{dotted-name} containing at least one dot, and a conversion function will be sought using the \method{search()} method of the data type registry used to load the schema. \subsection{Schema Elements \label{elements}} For each element, the content model is shown, followed by a description of how the element is used, and then a list of the available attributes. For each attribute, the type of the value is given as either the name of a \module{ZConfig} datatype or an XML attribute value type. Familiarity with XML's Document Type Definition language is helpful. The following elements are used to describe a schema: \begin{elementdesc}{schema}{description?, metadefault?, example?, import*, (sectiontype | abstracttype)*, (section | key | multisection | multikey)*} Document element for a \module{ZConfig} schema. \begin{attributedesc}{extends}{\datatype{space-separated-url-references}} A list of URLs of base schemas from which this section type will inherit key, section, and section type declarations. If omitted, this schema is defined using only the keys, sections, and section types contained within the \element{schema} element. \end{attributedesc} \begin{attributedesc}{datatype}{\datatype{basic-key} or \datatype{dotted-name}} The data type converter which will be applied to the value of this section. If the value is a \datatype{dotted-name} that begins with a period, the value of \attribute{prefix} will be pre-pended, if set. If any base schemas are listed in the \attribute{extends} attribute, the default value for this attribute comes from the base schemas. If the base schemas all use the same \attribute{datatype}, then that data type will be the default value for the extending schema. If there are no base schemas, the default value is \datatype{null}, which means that the \module{ZConfig} section object will be used unconverted. If the base schemas have different \attribute{datatype} definitions, you must explicitly define the \attribute{datatype} in the extending schema. \end{attributedesc} \begin{attributedesc}{handler}{\datatype{basic-key}} \end{attributedesc} \begin{attributedesc}{keytype}{\datatype{basic-key} or \datatype{dotted-name}} The data type converter which will be applied to keys found in this section. This can be used to constrain key values in different ways; two data types which may be especially useful are the \datatype{identifier} and \datatype{ipaddr-or-hostname} types. If the value is a \datatype{dotted-name} that begins with a period, the value of \attribute{prefix} will be pre-pended, if set. If any base schemas are listed in the \attribute{extends} attribute, the default value for this attribute comes from the base schemas. If the base schemas all use the same \attribute{keytype}, then that key type will be the default value for the extending schema. If there are no base schemas, the default value is \datatype{basic-key}. If the base schemas have different \attribute{keytype} definitions, you must explicitly define the \attribute{keytype} in the extending schema. \end{attributedesc} \begin{attributedesc}{prefix}{\datatype{dotted-name}} Prefix to be pre-pended in front of partial dotted-names that start with a period. The value of this attribute is used in all contexts with the \element{schema} element if it hasn't been overridden by an inner element with a \attribute{prefix} attribute. \end{attributedesc} \end{elementdesc} \begin{elementdesc}{description}{PCDATA} Descriptive text explaining the purpose the container of the \element{description} element. Most other elements can contain a \element{description} element as their first child. At most one \element{description} element may appear in a given context. \begin{attributedesc}{format}{NMTOKEN} Optional attribute that can be added to indicate what conventions are used to mark up the contained text. This is intended to serve as a hint for documentation extraction tools. Suggested values are: \begin{tableii}{l|l}{code}{Value}{Content Format} \lineii{plain}{\mimetype{text/plain}; blank lines separate paragraphs} \lineii{rest}{reStructuredText} \lineii{stx}{Classic Structured Text} \end{tableii} \end{attributedesc} \end{elementdesc} \begin{elementdesc}{example}{PCDATA} An example value. This serves only as documentation. \end{elementdesc} \begin{elementdesc}{metadefault}{PCDATA} A description of the default value, for human readers. This may include information about how a computed value is determined when the schema does not specify a default value. \end{elementdesc} \begin{elementdesc}{abstracttype}{description?} Define an abstract section type. \begin{attributedesc}{name}{\datatype{basic-key}} The name of the abstract section type; required. \end{attributedesc} \end{elementdesc} \begin{elementdesc}{sectiontype}{description?, (section | key | multisection | multikey)*} Define a concrete section type. \begin{attributedesc}{datatype}{\datatype{basic-key} or \datatype{dotted-name}} The data type converter which will be applied to the value of this section. If the value is a \datatype{dotted-name} that begins with a period, the value of \attribute{prefix} will be pre-pended, if set. If \attribute{datatype} is omitted and \attribute{extends} is used, the \attribute{datatype} from the section type identified by the \attribute{extends} attribute is used. \end{attributedesc} \begin{attributedesc}{extends}{\datatype{basic-key}} The name of a concrete section type from which this section type acquires all key and section declarations. This type does \emph{not} automatically implement any abstract section type implemented by the named section type. If omitted, this section is defined with only the keys and sections contained within the \element{sectiontype} element. The new section type is called a \emph{derived} section type, and the type named by this attribute is called the \emph{base} type. Values for the \attribute{datatype} and \attribute{keytype} attributes are acquired from the base type if not specified. \end{attributedesc} \begin{attributedesc}{implements}{\datatype{basic-key}} The name of an abstract section type which this concrete section type implements. If omitted, this section type does not implement any abstract type, and can only be used if it is specified directly in a schema or other section type. \end{attributedesc} \begin{attributedesc}{keytype}{\datatype{basic-key}} The data type converter which will be applied to keys found in this section. This can be used to constrain key values in different ways; two data types which may be especially useful are the \datatype{identifier} and \datatype{ipaddr-or-hostname} types. If the value is a \datatype{dotted-name} that begins with a period, the value of \attribute{prefix} will be pre-pended, if set. The default value is \datatype{basic-key}. If \attribute{keytype} is omitted and \attribute{extends} is used, the \attribute{keytype} from the section type identified by the \attribute{extends} attribute is used. \end{attributedesc} \begin{attributedesc}{name}{\datatype{basic-key}} The name of the section type; required. \end{attributedesc} \begin{attributedesc}{prefix}{\datatype{dotted-name}} Prefix to be pre-pended in front of partial dotted-names that start with a period. The value of this attribute is used in all contexts in the \element{sectiontype} element. If omitted, the prefix specified by a containing context is used if specified. \end{attributedesc} \end{elementdesc} \begin{elementdesc}{import}{EMPTY} Import a schema component. Exactly one of the attributes \attribute{package} and \attribute{src} must be specified. \begin{attributedesc}{file}{file name without directory information} Name of the component file within a package; if not specified, \file{component.xml} is used. This may only be given when \attribute{package} is used. (The \file{component.xml} file is always used when importing via \keyword{\%import} from a configuration file.) \end{attributedesc} \begin{attributedesc}{package}{\datatype{dotted-suffix}} Name of a Python package that contains the schema component being imported. The component will be loaded from the file identified by the \attribute{file} attribute, or \file{component.xml} if \attribute{file} is not specified. If the package name given starts with a dot (\character{.}), the name used will be the current prefix and the value of this attribute concatenated. \end{attributedesc} \begin{attributedesc}{src}{\datatype{url-reference}} URL to a separate schema which can provide useful types. The referenced resource must contain a schema, not a schema component. Section types defined or imported by the referenced schema are added to the schema containing the \element{import}; top-level keys and sections are ignored. \end{attributedesc} \end{elementdesc} \begin{elementdesc}{key}{description?, example?, metadefault?, default*} A \element{key} element is used to describe a key-value pair which may occur at most once in the section type or top-level schema in which it is listed. \begin{attributedesc}{attribute}{\datatype{identifier}} The name of the Python attribute which this key should be the value of on a \class{SectionValue} instance. This must be unique within the immediate contents of a section type or schema. If this attribute is not specified, an attribute name will be computed by converting hyphens in the key name to underscores. \end{attributedesc} \begin{attributedesc}{datatype}{\datatype{basic-key} or \datatype{dotted-name}} The data type converter which will be applied to the value of this key. If the value is a \datatype{dotted-name} that begins with a period, the value of \attribute{prefix} will be pre-pended, if set. \end{attributedesc} \begin{attributedesc}{default}{\datatype{string}} If the key-value pair is optional and this attribute is specified, the value of this attribute will be converted using the appropriate data type converter and returned to the application as the configured value. This attribute may not be specified if the \attribute{required} attribute is \code{yes}. \end{attributedesc} \begin{attributedesc}{handler}{\datatype{basic-key}} \end{attributedesc} \begin{attributedesc}{name}{\datatype{basic-key}} The name of the key, as it must be given in a configuration instance, or `\code{*}'. If the value is `\code{*}', any name not already specified as a key may be used, and the configuration value for the key will be a dictionary mapping from the key name to the value. In this case, the \attribute{attribute} attribute must be specified, and the data type for the key will be applied to each key which is found. \end{attributedesc} \begin{attributedesc}{required}{\code{yes|no}} Specifies whether the configuration instance is required to provide the key. If the value is \code{yes}, the \attribute{default} attribute may not be specified and an error will be reported if the configuration instance does not specify a value for the key. If the value is \code{no} (the default) and the configuration instance does not specify a value, the value reported to the application will be that specified by the \attribute{default} attribute, if given, or \code{None}. \end{attributedesc} \end{elementdesc} \begin{elementdesc}{multikey}{description?, example?, metadefault?, default*} A \element{multikey} element is used to describe a key-value pair which may occur any number of times in the section type or top-level schema in which it is listed. \begin{attributedesc}{attribute}{\datatype{identifier}} The name of the Python attribute which this key should be the value of on a \class{SectionValue} instance. This must be unique within the immediate contents of a section type or schema. If this attribute is not specified, an attribute name will be computed by converting hyphens in the key name to underscores. \end{attributedesc} \begin{attributedesc}{datatype}{\datatype{basic-key} or \datatype{dotted-name}} The data type converter which will be applied to the value of this key. If the value is a \datatype{dotted-name} that begins with a period, the value of \attribute{prefix} will be pre-pended, if set. \end{attributedesc} \begin{attributedesc}{handler}{\datatype{basic-key}} \end{attributedesc} \begin{attributedesc}{name}{\datatype{basic-key}} The name of the key, as it must be given in a configuration instance, or `\code{+}'. If the value is `\code{+}', any name not already specified as a key may be used, and the configuration value for the key will be a dictionary mapping from the key name to the value. In this case, the \attribute{attribute} attribute must be specified, and the data type for the key will be applied to each key which is found. \end{attributedesc} \begin{attributedesc}{required}{\code{yes|no}} Specifies whether the configuration instance is required to provide the key. If the value is \code{yes}, no \element{default} elements may be specified and an error will be reported if the configuration instance does not specify at least one value for the key. If the value is \code{no} (the default) and the configuration instance does not specify a value, the value reported to the application will be a list containing one element for each \element{default} element specified as a child of the \element{multikey}. Each value will be individually converted according to the \attribute{datatype} attribute. \end{attributedesc} \end{elementdesc} \begin{elementdesc}{default}{PCDATA} Each \element{default} element specifies a single default value for a \element{multikey}. This element can be repeated to produce a list of individual default values. The text contained in the element will be passed to the datatype conversion for the \element{multikey}. \begin{attributedesc}{key}{key type of the containing sectiontype} Key to associate with the default value. This is only used for defaults of a \element{key} or \element{multikey} with a \attribute{name} of \code{+}; in that case this attribute is required. It is an error to use the \attribute{key} attribute with a \element{default} element for a \element{multikey} with a name other than \code{+}. \begin{notice}[warning] The datatype of this attribute is that of the section type \emph{containing} the actual keys, not necessarily that of the section type which defines the key. If a derived section overrides the key type of the base section type, the actual key type used is that of the derived section. This can lead to confusing errors in schemas, though the \refmodule{ZConfig} package checks for this when the schema is loaded. This situation is particularly likely when a derived section type uses a key type which collapses multiple default keys which were not collapsed by the base section type. Consider this example schema: \begin{verbatim} some value some value
\end{verbatim} When this schema is loaded, a set of defaults for the \datatype{derived} section type is computed. Since \datatype{basic-key} is case-insensitive (everything is converted to lower case), \samp{foo} and \samp{Foo} are both converted to \samp{foo}, which clashes since \element{key} only allows one value for each key. \end{notice} \end{attributedesc} \end{elementdesc} \begin{elementdesc}{section}{description?} A \element{section} element is used to describe a section which may occur at most once in the section type or top-level schema in which it is listed. \begin{attributedesc}{attribute}{\datatype{identifier}} The name of the Python attribute which this section should be the value of on a \class{SectionValue} instance. This must be unique within the immediate contents of a section type or schema. If this attribute is not specified, an attribute name will be computed by converting hyphens in the section name to underscores, in which case the \attribute{name} attribute may not be \code{*} or \code{+}. \end{attributedesc} \begin{attributedesc}{handler}{\datatype{basic-key}} \end{attributedesc} \begin{attributedesc}{name}{\datatype{basic-key}} The name of the section, as it must be given in a configuration instance, \code{*}, or \code{+}. If the value is \code{*} or this attribute is omitted, any name not already specified as a key may be used. If the value is \code{*} or \code{+}, the \attribute{attribute} attribute must be specified. If the value is \code{*}, any name is allowed, or the name may be omitted. If the value is \code{+}, any name is allowed, but some name must be provided. \end{attributedesc} \begin{attributedesc}{required}{\code{yes|no}} Specifies whether the configuration instance is required to provide the section. If the value is \code{yes}, an error will be reported if the configuration instance does not include the section. If the value is \code{no} (the default) and the configuration instance does not include the section, the value reported to the application will be \code{None}. \end{attributedesc} \begin{attributedesc}{type}{\datatype{basic-key}} The section type which matching sections must implement. If the value names an abstract section type, matching sections in the configuration file must be of a type which specifies that it implements the named abstract type. If the name identifies a concrete type, the section type must match exactly. \end{attributedesc} \end{elementdesc} \begin{elementdesc}{multisection}{description?} A \element{multisection} element is used to describe a section which may occur any number of times in the section type or top-level schema in which it is listed. \begin{attributedesc}{attribute}{\datatype{identifier}} The name of the Python attribute which matching sections should be the value of on a \class{SectionValue} instance. This is required and must be unique within the immediate contents of a section type or schema. The \class{SectionValue} instance will contain a list of matching sections. \end{attributedesc} \begin{attributedesc}{handler}{\datatype{basic-key}} \end{attributedesc} \begin{attributedesc}{name}{\datatype{basic-key}} For a \element{multisection}, any name not already specified as a key may be used. If the value is \code{*} or \code{+}, the \attribute{attribute} attribute must be specified. If the value is \code{*} or this attribute is omitted, any name is allowed, or the name may be omitted. If the value is \code{+}, any name is allowed, but some name must be provided. No other value for the \attribute{name} attribute is allowed for a \element{multisection}. \end{attributedesc} \begin{attributedesc}{required}{\code{yes|no}} Specifies whether the configuration instance is required to provide at least one matching section. If the value is \code{yes}, an error will be reported if the configuration instance does not include the section. If the value is \code{no} (the default) and the configuration instance does not include the section, the value reported to the application will be \code{None}. \end{attributedesc} \begin{attributedesc}{type}{\datatype{basic-key}} The section type which matching sections must implement. If the value names an abstract section type, matching sections in the configuration file must be of types which specify that they implement the named abstract type. If the name identifies a concrete type, the section type must match exactly. \end{attributedesc} \end{elementdesc} \subsection{Schema Components \label{schema-components}} XXX need more explanation \module{ZConfig} supports schema components that can be provided by disparate components, and allows them to be knit together into concrete schema for applications. Components cannot add additional keys or sections in the application schema. A schema \dfn{component} is allowed to define new abstract and section types. Components are identified using a dotted-name, similar to a Python module name. For example, one component may be \code{zodb.storage}. Schema components are stored alongside application code since they directly reference datatype code. Schema components are provided by Python packages. The component definition is normally stored in the file \file{component.xml}; an alternate filename may be specified using the \attribute{file} attribute of the \element{import} element. Components imported using the \keyword{\%import} keyword from a configuration file must be named \file{component.xml}. The component defines the types provided by that component; it must have a \element{component} element as the document element. The following element is used as the document element for schema components. Note that schema components do not allow keys and sections to be added to the top-level of a schema; they serve only to provide type definitions. \begin{elementdesc}{component}{description?, (abstracttype | sectiontype)*} The top-level element for schema components. \begin{attributedesc}{prefix}{\datatype{dotted-name}} Prefix to be pre-pended in front of partial dotted-names that start with a period. The value of this attribute is used in all contexts within the \element{component} element if it hasn't been overridden by an inner element with a \attribute{prefix} attribute. \end{attributedesc} \end{elementdesc} \subsection{Referring to Files in Packages} The \attribute{extends} attribute of the \element{schema} element is used to refer to files containing base schema; sometimes it makes sense to refer to a base schema relative to the Python package that provides it. For this purpose, ZConfig supports the special \code{package:} URL scheme. The \code{package:} URL scheme is straightforward, and contains three parts: the scheme name, the package name, and a relative path. The relative path is searched for using the named package's \code{__path__} if it's a conventional filesystem package, or using the package's loader if that supports resource access (such as the loader for eggs and other ZIP-file based packages). The basic form of the \code{package:} URL is \begin{alltt} package:\var{package.name}:\var{relative-path} \end{alltt} The package name must be fully specified; the current prefix, if any, is not used. If the named package is contained in an egg or ZIP file, the resource identified by the relative path must reside in the same egg or ZIP file. The \code{package:} URL scheme is generally available everywhere ZConfig supports loading text from URLs directly, but applications using ZConfig do not automatically acquire general support for this. \section{Standard \module{ZConfig} Datatypes\label{standard-datatypes}} There are a number of data types which can be identified using the \attribute{datatype} attribute on \element{key}, \element{sectiontype}, and \element{schema} elements. Applications may extend the set of datatypes by calling the \method{register()} method of the data type registry being used or by using Python dotted-names to refer to conversion routines defined in code. The following data types are provided by the default type registry. \begin{definitions} \term{\datatype{basic-key}} The default data type for a key in a ZConfig configuration file. The result of conversion is always lower-case, and matches the regular expression \regexp{[a-z][-._a-z0-9]*}. \term{\datatype{boolean}} Convert a human-friendly string to a boolean value. The names \code{yes}, \code{on}, and \code{true} convert to \constant{True}, while \code{no}, \code{off}, and \code{false} convert to \constant{False}. Comparisons are case-insensitive. All other input strings are disallowed. \term{\datatype{byte-size}} A specification of a size, with byte multiplier suffixes (for example, \samp{128MB}). Suffixes are case insensitive and may be \samp{KB}, \samp{MB}, or \samp{GB} \term{\datatype{dotted-name}} A string consisting of one or more \datatype{identifier} values separated by periods (\character{.}). \term{\datatype{dotted-suffix}} A string consisting of one or more \datatype{identifier} values separated by periods (\character{.}), possibly prefixed by a period. This can be used to indicate a dotted name that may be specified relative to some base dotted name. \term{\datatype{existing-dirpath}} Validates that the directory portion of a pathname exists. For example, if the value provided is \file{/foo/bar}, \file{/foo} must be an existing directory. No conversion is performed. \term{\datatype{existing-directory}} Validates that a directory by the given name exists on the local filesystem. No conversion is performed. \term{\datatype{existing-file}} Validates that a file by the given name exists. No conversion is performed. \term{\datatype{existing-path}} Validates that a path (file, directory, or symlink) by the given name exists on the local filesystem. No conversion is performed. \term{\datatype{float}} A Python float. \code{Inf}, \code{-Inf}, and \code{NaN} are not allowed. \term{\datatype{identifier}} Any valid Python identifier. \term{\datatype{inet-address}} An Internet address expressed as a \code{(\var{hostname}, \var{port})} pair. If only the port is specified, the default host will be returned for \var{hostname}. The default host is \code{localhost} on Windows and the empty string on all other platforms. If the port is omitted, \code{None} will be returned for \var{port}. IPv6 addresses can be specified in colon-separated notation; if both host and port need to be specified, the bracketed form (\code{[addr]:port}) must be used. \term{\datatype{inet-binding-address}} An Internet address expressed as a \code{(\var{hostname}, \var{port})} pair. The address is suitable for binding a socket. If only the port is specified, the default host will be returned for \var{hostname}. The default host is the empty string on all platforms. If the port is omitted, \code{None} will be returned for \var{port}. \term{\datatype{inet-connection-address}} An Internet address expressed as a \code{(\var{hostname}, \var{port})} pair. The address is suitable for connecting a socket to a server. If only the port is specified, \code{'127.0.0.1'} will be returned for \var{hostname}. If the port is omitted, \code{None} will be returned for \var{port}. \term{\datatype{integer}} Convert a value to an integer. This will be a Python \class{int} if the value is in the range allowed by \class{int}, otherwise a Python \class{long} is returned. \term{\datatype{ipaddr-or-hostname}} Validates a valid IP address or hostname. If the first character is a digit, the value is assumed to be an IP address. If the first character is not a digit, the value is assumed to be a hostname. Strings containing colons are considered IPv6 address. Hostnames are converted to lower case. \term{\datatype{locale}} Any valid locale specifier accepted by the available \function{locale.setlocale()} function. Be aware that only the \code{'C'} locale is supported on some platforms. \term{\datatype{null}} No conversion is performed; the value passed in is the value returned. This is the default data type for section values. \term{\datatype{port-number}} Returns a valid port number as an integer. Validity does not imply that any particular use may be made of the port, however. For example, port number lower than 1024 generally cannot be bound by non-root users. \term{\datatype{socket-address}} An address for a socket. The converted value is an object providing two attributes. \member{family} specifies the address family (\constant{AF_INET} or \constant{AF_UNIX}), with \code{None} instead of \constant{AF_UNIX} on platforms that don't support it. The \member{address} attribute will be the address that should be passed to the socket's \method{bind()} method. If the family is \constant{AF_UNIX}, the specific address will be a pathname; if the family is \constant{AF_INET}, the second part will be the result of the \datatype{inet-address} conversion. \term{\datatype{string}} Returns the input value as a string. If the source is a Unicode string, this implies that it will be checked to be simple 7-bit \ASCII. This is the default data type for values in configuration files. \term{\datatype{time-interval}} A specification of a time interval in seconds, with multiplier suffixes (for example, \code{12h}). Suffixes are case insensitive and may be \samp{s} (seconds), \samp{m} (minutes), \samp{h} (hours), or \samp{d} (days). \term{\datatype{timedelta}} Similar to the \datatype{time-interval}, this data type returns a Python datetime.timedelta object instead of a float. The set of suffixes recognized by \datatype{timedelta} are: \samp{w} (weeks), \samp{d} (days), \samp{h} (hours), \samp{m} (minutes), \samp{s} (seconds). Values may be floats, for example: \code{4w 2.5d 7h 12m 0.001s}. \end{definitions} \section{Standard \module{ZConfig} Schema Components \label{standard-components}} \module{ZConfig} provides a few convenient schema components as part of the package. These may be used directly or can server as examples for creating new components. \subsection{\module{ZConfig.components.basic}} The \module{ZConfig.components.basic} package provides small components that can be helpful in composing application-specific components and schema. There is no large functionality represented by this package. The default component provided by this package simply imports all of the smaller components. This can be imported using \begin{verbatim} \end{verbatim} Each of the smaller components is documented directly; importing these selectively can reduce the time it takes to load a schema slightly, and allows replacing the other basic components with alternate components (by using different imports that define the same type names) if desired. \subsubsection{The Mapping Section Type \label{basic-mapping}} There is a basic section type that behaves like a simple Python mapping; this can be imported directly using \begin{verbatim} \end{verbatim} This defines a single section type, \datatype{ZConfig.basic.mapping}. When this is used, the section value is a Python dictionary mapping keys to string values. This type is intended to be used by extending it in simple ways. The simplest is to create a new section type name that makes more sense for the application: \begin{verbatim}
\end{verbatim} This allows a configuration to contain a mapping from \datatype{basic-key} names to string values like this: \begin{verbatim} This that and the other \end{verbatim} The value of the configuration object's \member{map} attribute would then be the dictionary \begin{verbatim} {'this': 'that', 'and': 'the other', } \end{verbatim} (Recall that the \datatype{basic-key} data type converts everything to lower case.) Perhaps a more interesting application of \datatype{ZConfig.basic.mapping} is using the derived type to override the \attribute{keytype}. If we have the conversion function: \begin{verbatim} def email_address(value): userid, hostname = value.split("@", 1) hostname = hostname.lower() # normalize what we know we can return "%s@%s" % (userid, hostname) \end{verbatim} then we can use this as the key type for a derived mapping type: \begin{verbatim}
\end{verbatim} \subsection{\module{ZConfig.components.logger}} The \module{ZConfig.components.logger} package provides configuration support for the \ulink{\module{logging} package} {http://docs.python.org/library/logging.html} in Python's standard library. This component can be imported using \begin{verbatim} \end{verbatim} This component defines two abstract types and several concrete section types. These can be imported as a unit, as above, or as four smaller components usable in creating alternate logging packages. The first of the four smaller components contains the abstract types, and can be imported using \begin{verbatim} \end{verbatim} The two abstract types imported by this are: \begin{definitions} \term{\datatype{ZConfig.logger.log}} Logger objects are represented by this abstract type. \term{\datatype{ZConfig.logger.handler}} Each logger object can have one or more ``handlers'' associated with them. These handlers are responsible for writing logging events to some form of output stream using appropriate formatting. The output stream may be a file on a disk, a socket communicating with a server on another system, or a series of \code{syslog} messages. Section types which implement this type represent these handlers. \end{definitions} The second and third of the smaller components provides section types that act as factories for \class{logging.Logger} objects. These can be imported using \begin{verbatim} \end{verbatim} The types defined in these components implement the \datatype{ZConfig.logger.log} abstract type. The \file{eventlog.xml} component defines an \datatype{eventlog} type which represents the root logger from the the \module{logging} package (the return value of \function{logging.getLogger()}), while the \file{logger.xml} component defines a \datatype{logger} section type which represents a named logger (as returned by \function{logging.getLogger(\var{name})}). The third of the smaller components provides section types that are factories for \class{logging.Handler} objects. This can be imported using \begin{verbatim} \end{verbatim} The types defined in this component implement the \datatype{ZConfig.logger.handler} abstract type. The configuration objects provided by both the logger and handler types are factories for the finished loggers and handlers. These factories should be called with no arguments to retrieve the logger or log handler objects. Calling the factories repeatedly will cause the same objects to be returned each time, so it's safe to simply call them to retrieve the objects. The factories for the logger objects, whether the \datatype{eventlog} or \datatype{logger} section type is used, provide a \method{reopen()} method which may be called to close any log files and re-open them. This is useful when using a \UNIX{} signal to effect log file rotation: the signal handler can call this method, and not have to worry about what handlers have been registered for the logger. There is also a function in the \module{ZConfig.components.logger.loghandler} module that re-opens all open log files created using ZConfig configuraiton: \begin{funcdesc}{reopenFiles}{} Closes and re-opens all the log files held open by handlers created by the factories for \code{logfile} sections. This is intended to help support log rotation for applications. \end{funcdesc} Building an application that uses the logging components is fairly straightforward. The schema needs to import the relevant components and declare their use: \begin{verbatim}
\end{verbatim} In the application, the schema and configuration file should be loaded normally. Once the configuration object is available, the logger factory should be called to configure Python's \module{logging} package: \begin{verbatim} import os import ZConfig def run(configfile): schemafile = os.path.join(os.path.dirname(__file__), "schema.xml") schema = ZConfig.loadSchema(schemafile) config, handlers = ZConfig.loadConfig(schema, configfile) # configure the logging package: config.eventlog() # now do interesting things \end{verbatim} An example configuration file for this application may look like this: \begin{verbatim} level info path /var/log/myapp format %(asctime)s %(levelname)s %(name)s %(message)s # locale-specific date/time representation dateformat %c level error address syslog.example.net:514 format %(levelname)s %(name)s %(message)s \end{verbatim} Refer to the \module{logging} package documentation for the names available in the message format strings (the \code{format} key in the log handlers). The date format strings (the \code{dateformat} key in the log handlers) are the same as those accepted by the \function{time.strftime()} function. \subsubsection{Configuring the email logger} ZConfig has support for Python's STMTPHandler via the handler. \begin{verbatim} to sysadmin@example.com to john@example.com from zlog-user@example.com level fatal smtp-username john smtp-password johnpw \end{verbatim} For details about the SMTPHandler see the Python \module{logging} module. \begin{seealso} \seepep{282}{A Logging System} {The proposal which described the logging feature for inclusion in the Python standard library.} \seelink{http://docs.python.org/library/logging.html} {\module{logging} --- Logging facility for Python} {Python's \module{logging} package documentation, from the \citetitle[http://docs.python.org/library/] {Python Library Reference}.} \seelink{http://www.red-dove.com/python_logging.html} {Original Python \module{logging} package} {This is the original source for the \module{logging} package. This is mostly of historical interest.} \end{seealso} \section{Using Components to Extend Schema} % XXX This section needs a lot of work, but should get people started % who really want to add new pieces to ZConfig-configured applications. It is possible to use schema components and the \keyword{\%import} construct to extend the set of section types available for a specific configuration file, and allow the new components to be used in place of standard components. The key to making this work is the use of abstract section types. Wherever the original schema accepts an abstract type, it is possible to load new implementations of the abstract type and use those instead of, or in addition to, the implementations loaded by the original schema. Abstract types are generally used to represent interfaces. Sometimes these are interfaces for factory objects, and sometimes not, but there's an interface that the new component needs to implement. What interface is required should be documented in the \element{description} element in the \element{abstracttype} element; this may be by reference to an interface specified in a Python module or described in some other bit of documentation. The following things need to be created to make the new component usable from the configuration file: \begin{enumerate} \item An implementation of the required interface. \item A schema component that defines a section type that contains the information needed to construct the component. \item A ``datatype'' function that converts configuration data to an instance of the component. \end{enumerate} For simplicity, let's assume that the implementation is defined by a Python class. The example component we build here will be in the \module{noise} package, but any package will do. Components loadable using \keyword{\%import} must be contained in the \file{component.xml} file; alternate filenames may not be selected by the \keyword{\%import} construct. Create a ZConfig component that provides a section type to support your component. The new section type must declare that it implements the appropriate abstract type; it should probably look something like this: \begin{verbatim} Port number to listen on. Silly way to specify a noise generation algorithm. \end{verbatim} This example uses one of the standard ZConfig datatypes, \datatype{port-number}, and requires two additional types to be provided by the \module{noise.server} module: \class{NoiseServerFactory} and \function{noise_color()}. The \function{noise_color()} function is a datatype conversion for a key, so it accepts a string and returns the value that should be used: \begin{verbatim} _noise_colors = { # color -> r,g,b 'white': (255, 255, 255), 'pink': (255, 182, 193), } def noise_color(string): if string in _noise_colors: return _noise_colors[string] else: raise ValueError('unknown noise color: %r' % string) \end{verbatim} \class{NoiseServerFactory} is a little different, as it's the datatype function for a section rather than a key. The parameter isn't a string, but a section value object with two attributes, \member{port} and \member{color}. Since the \datatype{ZServer.server} abstract type requires that the component returned is a factory object, the datatype function can be implemented at the constructor for the class of the factory object. (If the datatype function could select different implementation classes based on the configuration values, it makes more sense to use a simple function that returns the appropriate implementation.) A class that implements this datatype might look like this: \begin{verbatim} from ZServer.datatypes import ServerFactory from noise.generator import WhiteNoiseGenerator, PinkNoiseGenerator class NoiseServerFactory(ServerFactory): def __init__(self, section): # host and ip will be initialized by ServerFactory.prepare() self.host = None self.ip = None self.port = section.port self.color = section.color def create(self): if self.color == 'white': generator = WhiteNoiseGenerator() else: generator = PinkNoiseGenerator() return NoiseServer(self.ip, self.port, generator) \end{verbatim} You'll need to arrange for the package containing this component to be available on Python's \code{sys.path} before the configuration file is loaded; this is mostly easily done by manipulating the \envvar{PYTHONPATH} environment variable. Your configuration file can now include the following to load and use your new component: \begin{verbatim} %import noise port 1234 color white \end{verbatim} \section{\module{ZConfig} --- Basic configuration support} \declaremodule{}{ZConfig} \modulesynopsis{Configuration package.} The main \module{ZConfig} package exports these convenience functions: \begin{funcdesc}{loadConfig}{schema, url\optional{, overrides}} Load and return a configuration from a URL or pathname given by \var{url}. \var{url} may be a URL, absolute pathname, or relative pathname. Fragment identifiers are not supported. \var{schema} is a reference to a schema loaded by \function{loadSchema()} or \function{loadSchemaFile()}. The return value is a tuple containing the configuration object and a composite handler that, when called with a name-to-handler mapping, calls all the handlers for the configuration. The optional \var{overrides} argument represents information derived from command-line arguments. If given, it must be either a sequence of value specifiers, or \code{None}. A \dfn{value specifier} is a string of the form \code{\var{optionpath}=\var{value}}. The \var{optionpath} specifies the ``full path'' to the configuration setting: it can contain a sequence of names, separated by \character{/} characters. Each name before the last names a section from the configuration file, and the last name corresponds to a key within the section identified by the leading section names. If \var{optionpath} contains only one name, it identifies a key in the top-level schema. \var{value} is a string that will be treated just like a value in the configuration file. \end{funcdesc} \begin{funcdesc}{loadConfigFile}{schema, file\optional{, url\optional{, overrides}}} Load and return a configuration from an opened file object. If \var{url} is omitted, one will be computed based on the \member{name} attribute of \var{file}, if it exists. If no URL can be determined, all \keyword{\%include} statements in the configuration must use absolute URLs. \var{schema} is a reference to a schema loaded by \function{loadSchema()} or \function{loadSchemaFile()}. The return value is a tuple containing the configuration object and a composite handler that, when called with a name-to-handler mapping, calls all the handlers for the configuration. The \var{overrides} argument is the same as for the \function{loadConfig()} function. \end{funcdesc} \begin{funcdesc}{loadSchema}{url} Load a schema definition from the URL \var{url}. \var{url} may be a URL, absolute pathname, or relative pathname. Fragment identifiers are not supported. The resulting schema object can be passed to \function{loadConfig()} or \function{loadConfigFile()}. The schema object may be used as many times as needed. \end{funcdesc} \begin{funcdesc}{loadSchemaFile}{file\optional{, url}} Load a schema definition from the open file object \var{file}. If \var{url} is given and not \code{None}, it should be the URL of resource represented by \var{file}. If \var{url} is omitted or \code{None}, a URL may be computed from the \member{name} attribute of \var{file}, if present. The resulting schema object can be passed to \function{loadConfig()} or \function{loadConfigFile()}. The schema object may be used as many times as needed. \end{funcdesc} The following exceptions are defined by this package: \begin{excdesc}{ConfigurationError} Base class for exceptions specific to the \module{ZConfig} package. All instances provide a \member{message} attribute that describes the specific error, and a \member{url} attribute that gives the URL of the resource the error was located in, or \constant{None}. \end{excdesc} \begin{excdesc}{ConfigurationSyntaxError} Exception raised when a configuration source does not conform to the allowed syntax. In addition to the \member{message} and \member{url} attributes, exceptions of this type offer the \member{lineno} attribute, which provides the line number at which the error was detected. \end{excdesc} \begin{excdesc}{DataConversionError} Raised when a data type conversion fails with \exception{ValueError}. This exception is a subclass of both \exception{ConfigurationError} and \exception{ValueError}. The \function{str()} of the exception provides the explanation from the original \exception{ValueError}, and the line number and URL of the value which provoked the error. The following additional attributes are provided: \begin{tableii}{l|l}{member}{Attribute}{Value} \lineii{colno} {column number at which the value starts, or \code{None}} \lineii{exception} {the original \exception{ValueError} instance} \lineii{lineno} {line number on which the value starts} \lineii{message} {\function{str()} returned by the original \exception{ValueError}} \lineii{value} {original value passed to the conversion function} \lineii{url} {URL of the resource providing the value text} \end{tableii} \end{excdesc} \begin{excdesc}{SchemaError} Raised when a schema contains an error. This exception type provides the attributes \member{url}, \member{lineno}, and \member{colno}, which provide the source URL, the line number, and the column number at which the error was detected. These attributes may be \code{None} in some cases. \end{excdesc} \begin{excdesc}{SchemaResourceError} Raised when there's an error locating a resource required by the schema. This is derived from \exception{SchemaError}. Instances of this exception class add the attributes \member{filename}, \member{package}, and \member{path}, which hold the filename searched for within the package being loaded, the name of the package, and the \code{__path__} attribute of the package itself (or \constant{None} if it isn't a package or could not be imported). \end{excdesc} \begin{excdesc}{SubstitutionReplacementError} Raised when the source text contains references to names which are not defined in \var{mapping}. The attributes \member{source} and \member{name} provide the complete source text and the name (converted to lower case) for which no replacement is defined. \end{excdesc} \begin{excdesc}{SubstitutionSyntaxError} Raised when the source text contains syntactical errors. \end{excdesc} \subsection{Basic Usage} The simplest use of \refmodule{ZConfig} is to load a configuration based on a schema stored in a file. This example loads a configuration file specified on the command line using a schema in the same directory as the script: \begin{verbatim} import os import sys import ZConfig try: myfile = __file__ except NameError: myfile = os.path.realpath(sys.argv[0]) mydir = os.path.dirname(myfile) schema = ZConfig.loadSchema(os.path.join(mydir, 'schema.xml')) conf, handler = ZConfig.loadConfig(schema, sys.argv[1]) \end{verbatim} If the schema file contained this schema: \begin{verbatim} \end{verbatim} and the file specified on the command line contained this text: \begin{verbatim} # sample configuration server www.example.com \end{verbatim} then the configuration object \code{conf} loaded above would have two attributes: \begin{tableii}{l|l}{member}{Attribute}{Value} \lineii{server}{\code{'www.example.com'}} \lineii{attempts}{\code{5}} \end{tableii} \section{\module{ZConfig.datatypes} --- Default data type registry} \declaremodule{}{ZConfig.datatypes} \modulesynopsis{Default implementation of a data type registry} The \module{ZConfig.datatypes} module provides the implementation of the default data type registry and all the standard data types supported by \module{ZConfig}. A number of convenience classes are also provided to assist in the creation of additional data types. A \dfn{datatype registry} is an object that provides conversion functions for data types. The interface for a registry is fairly simple. A \dfn{conversion function} is any callable object that accepts a single argument and returns a suitable value, or raises an exception if the input value is not acceptable. \exception{ValueError} is the preferred exception for disallowed inputs, but any other exception will be properly propagated. \begin{classdesc}{Registry}{\optional{stock}} Implementation of a simple type registry. If given, \var{stock} should be a mapping which defines the ``built-in'' data types for the registry; if omitted or \code{None}, the standard set of data types is used (see section~\ref{standard-datatypes}, ``Standard \module{ZConfig} Datatypes''). \end{classdesc} \class{Registry} objects have the following methods: \begin{methoddesc}{get}{name} Return the type conversion routine for \var{name}. If the conversion function cannot be found, an (unspecified) exception is raised. If the name is not provided in the stock set of data types by this registry and has not otherwise been registered, this method uses the \method{search()} method to load the conversion function. This is the only method the rest of \module{ZConfig} requires. \end{methoddesc} \begin{methoddesc}{register}{name, conversion} Register the data type name \var{name} to use the conversion function \var{conversion}. If \var{name} is already registered or provided as a stock data type, \exception{ValueError} is raised (this includes the case when \var{name} was found using the \method{search()} method). \end{methoddesc} \begin{methoddesc}{search}{name} This is a helper method for the default implementation of the \method{get()} method. If \var{name} is a Python dotted-name, this method loads the value for the name by dynamically importing the containing module and extracting the value of the name. The name must refer to a usable conversion function. \end{methoddesc} The following classes are provided to define conversion functions: \begin{classdesc}{MemoizedConversion}{conversion} Simple memoization for potentially expensive conversions. This conversion helper caches each successful conversion for re-use at a later time; failed conversions are not cached in any way, since it is difficult to raise a meaningful exception providing information about the specific failure. \end{classdesc} \begin{classdesc}{RangeCheckedConversion}{conversion\optional{, min\optional{, max}}} Helper that performs range checks on the result of another conversion. Values passed to instances of this conversion are converted using \var{conversion} and then range checked. \var{min} and \var{max}, if given and not \code{None}, are the inclusive endpoints of the allowed range. Values returned by \var{conversion} which lay outside the range described by \var{min} and \var{max} cause \exception{ValueError} to be raised. \end{classdesc} \begin{classdesc}{RegularExpressionConversion}{regex} Conversion that checks that the input matches the regular expression \var{regex}. If it matches, returns the input, otherwise raises \exception{ValueError}. \end{classdesc} \section{\module{ZConfig.loader} --- Resource loading support} \declaremodule{}{ZConfig.loader} \modulesynopsis{Support classes for resource loading} This module provides some helper classes used by the primary APIs exported by the \module{ZConfig} package. These classes may be useful for some applications, especially applications that want to use a non-default data type registry. \begin{classdesc}{Resource}{file, url\optional{, fragment}} Object that allows an open file object and a URL to be bound together to ease handling. Instances have the attributes \member{file}, \member{url}, and \member{fragment} which store the constructor arguments. These objects also have a \method{close()} method which will call \method{close()} on \var{file}, then set the \member{file} attribute to \code{None} and the \member{closed} to \constant{True}. \end{classdesc} \begin{classdesc}{BaseLoader}{} Base class for loader objects. This should not be instantiated directly, as the \method{loadResource()} method must be overridden for the instance to be used via the public API. \end{classdesc} \begin{classdesc}{ConfigLoader}{schema} Loader for configuration files. Each configuration file must conform to the schema \var{schema}. The \method{load*()} methods return a tuple consisting of the configuration object and a composite handler. \end{classdesc} \begin{classdesc}{SchemaLoader}{\optional{registry}} Loader that loads schema instances. All schema loaded by a \class{SchemaLoader} will use the same data type registry. If \var{registry} is provided and not \code{None}, it will be used, otherwise an instance of \class{ZConfig.datatypes.Registry} will be used. \end{classdesc} \subsection{Loader Objects} Loader objects provide a general public interface, an interface which subclasses must implement, and some utility methods. The following methods provide the public interface: \begin{methoddesc}[loader]{loadURL}{url} Open and load a resource specified by the URL \var{url}. This method uses the \method{loadResource()} method to perform the actual load, and returns whatever that method returns. \end{methoddesc} \begin{methoddesc}[loader]{loadFile}{file\optional{, url}} Load from an open file object, \var{file}. If given and not \code{None}, \var{url} should be the URL of the resource represented by \var{file}. If omitted or \code{None}, the \member{name} attribute of \var{file} is used to compute a \code{file:} URL, if present. This method uses the \method{loadResource()} method to perform the actual load, and returns whatever that method returns. \end{methoddesc} The following method must be overridden by subclasses: \begin{methoddesc}[loader]{loadResource}{resource} Subclasses of \class{BaseLoader} must implement this method to actually load the resource and return the appropriate application-level object. \end{methoddesc} The following methods can be used as utilities: \begin{methoddesc}[loader]{isPath}{s} Return true if \var{s} should be considered a filesystem path rather than a URL. \end{methoddesc} \begin{methoddesc}[loader]{normalizeURL}{url-or-path} Return a URL for \var{url-or-path}. If \var{url-or-path} refers to an existing file, the corresponding \code{file:} URL is returned. Otherwise \var{url-or-path} is checked for sanity: if it does not have a schema, \exception{ValueError} is raised, and if it does have a fragment identifier, \exception{ConfigurationError} is raised. This uses \method{isPath()} to determine whether \var{url-or-path} is a URL of a filesystem path. \end{methoddesc} \begin{methoddesc}[loader]{openResource}{url} Returns a resource object that represents the URL \var{url}. The URL is opened using the \function{urllib2.urlopen()} function, and the returned resource object is created using \method{createResource()}. If the URL cannot be opened, \exception{ConfigurationError} is raised. \end{methoddesc} \begin{methoddesc}[loader]{createResource}{file, url} Returns a resource object for an open file and URL, given as \var{file} and \var{url}, respectively. This may be overridden by a subclass if an alternate resource implementation is desired. \end{methoddesc} \section{\module{ZConfig.cmdline} --- Command-line override support} \declaremodule{}{ZConfig.cmdline} \modulesynopsis{Support for command-line overrides for configuration settings.} This module exports an extended version of the \class{ConfigLoader} class from the \refmodule{ZConfig.loader} module. This provides support for overriding specific settings from the configuration file from the command line, without requiring the application to provide specific options for everything the configuration file can include. \begin{classdesc}{ExtendedConfigLoader}{schema} Construct a \class{ConfigLoader} subclass that adds support for command-line overrides. \end{classdesc} The following additional method is provided, and is the only way to provide position information to associate with command-line parameters: \begin{methoddesc}{addOption}{spec\optional{, pos}} Add a single value to the list of overridden values. The \var{spec} argument is a value specified, as described for the \function{\refmodule{ZConfig}.loadConfig()} function. A source position for the specifier may be given as \var{pos}. If \var{pos} is specified and not \code{None}, it must be a sequence of three values. The first is the URL of the source (or some other identifying string). The second and third are the line number and column of the setting. These position information is only used to construct a \exception{DataConversionError} when data conversion fails. \end{methoddesc} \section{\module{ZConfig.substitution} --- String substitution} \declaremodule{}{ZConfig.substitution} \modulesynopsis{Shell-style string substitution helper.} This module provides a basic substitution facility similar to that found in the Bourne shell (\program{sh} on most \UNIX{} platforms). The replacements supported by this module include: \begin{tableiii}{l|l|c}{code}{Source}{Replacement}{Notes} \lineiii{\$\$}{\code{\$}}{(1)} \lineiii{\$\var{name}}{The result of looking up \var{name}}{(2)} \lineiii{\$\{\var{name}\}}{The result of looking up \var{name}}{} \end{tableiii} \noindent Notes: \begin{description} \item[(1)] This is different from the Bourne shell, which uses \code{\textbackslash\$} to generate a \character{\$} in the result text. This difference avoids having as many special characters in the syntax. \item[(2)] Any character which immediately follows \var{name} may not be a valid character in a name. \end{description} In each case, \var{name} is a non-empty sequence of alphanumeric and underscore characters not starting with a digit. If there is not a replacement for \var{name}, the exception \exception{SubstitutionReplacementError} is raised. Note that the lookup is expected to be case-insensitive; this module will always use a lower-case version of the name to perform the query. This module provides these functions: \begin{funcdesc}{substitute}{s, mapping} Substitute values from \var{mapping} into \var{s}. \var{mapping} can be a \class{dict} or any type that supports the \method{get()} method of the mapping protocol. Replacement values are copied into the result without further interpretation. Raises \exception{SubstitutionSyntaxError} if there are malformed constructs in \var{s}. \end{funcdesc} \begin{funcdesc}{isname}{s} Returns \constant{True} if \var{s} is a valid name for a substitution text, otherwise returns \constant{False}. \end{funcdesc} \subsection{Examples} \begin{verbatim} >>> from ZConfig.substitution import substitute >>> d = {'name': 'value', ... 'top': '$middle', ... 'middle' : 'bottom'} >>> >>> substitute('$name', d) 'value' >>> substitute('$top', d) '$middle' \end{verbatim} \appendix \section{Schema Document Type Definition \label{schema-dtd}} The following is the XML Document Type Definition for \module{ZConfig} schema: \verbatiminput{schema.dtd} \end{document} zope2.13-2.13.21/source/ZConfig/doc/zconfig.pdf0000644000175000017500000057075612214017462017720 0ustar arnauarnau%PDF-1.4 %ÐÔÅØ 28 0 obj << /Length 2046 /Filter /FlateDecode >> stream xÚíZMsÛ6½ûWð(ã“ zKœd&™dšÆNÛi’MÑ6}U¤ê¸¿¾KbI‚"H1I{Š'žÐÁ·ËÝ· H, ðšÃ ’õÅ‘Ïg1ü Cd(ËùŸh°„‘W%Æ„Á}…Y2Œàº .Ï~iî[À² \÷éÕÙù n.‰Ž4 ®n.(‰"„Z&dpµ >Ìþ¸Øn>RÊoç ®£ÙÛ¹¤³8™s:ûߦvð]z3t–îÓM’Î?]½:!àyŒ¥¸]Y¡T°àðٕߥ«4Îq N"Bí­@ŠI"dXݺa ¸KN”`Hj»Ãû.¶ûùž½ƒ+fE¶Ý bB–«¨P&pna–Ptöd·ÏVöWNYEâìùUã4©¡& ”$nå;!F‚»•¬ Ÿ[ÿÖØ…®xe@æxÅŠÍ]Qì~:?¿¿¿Ÿ‡tFþ™35+­„ I¶ëócZJÒ¥&L2%¢G^kK„G†xŠkB¾–'×y±“¢ñb‹_0Éd°6ƒ—ÂÑWwYXn“Ã:Ýå_l¶LódŸ]§8YÜ¥v<Øñ;o–vðÉÛ—vä§8”mìH‚xØÛ·[M–#«zé›2ÊQpÔn»8±½±ã±ýæZ;/âÕªYÎî÷YQ¤Uì”ùÅà+|5ס¢¾Ê2ê ઻ ŒY;æútáÖušÜÅ›,_[ŒÅŠYVäéêæø¾Ê0{ȳͭŒíHžÜ¥ëØå»4ÉÊ;ç9µö)8øû›×Ä›Zû†jH±2F0ß!Ý‹ÊGñÒ!!{hŽf@©0®Ž¹6ulÎÁ×”Î^n Èàh¶]’:‰Ýç3)ˆ¢¬C¢ó5jœƒ9¢Ìt‰pŸÅ WLšÓ·8¿Å8²_ôèÒ&DZñ#Tuèxl· q2é]FGÏ‹B°V’Bš1j>BÖ>ՕߣõìCIõêÁæç_ â–6ÖU-jÈA6Žs¥¡Àt÷=T£ÆÉòé.[Hsïìǹ0ÍÙ aB¡`L ;5ƒc`\Í5te üRb¬Ñ—(PYqhC"Ãë¯sÆ@ëW‡´§^œC¥ƒ’ë÷Ä¢Æ9Ã);¦é.>†ƒFz„Th(;ü¤Ž¶0¯Œâtåp*úT¼F:¾F18#,4.3_@XÐ(±ZR]vj(qBND¨¦%N‹NÄX—4ŠzY÷ ¥º®Òµ¯ ³HÀ‚u(ùŠŠE³a@GÁ†£Cç1%¾=‡ãGQhÀ§…OŽ Áàážà¹hêãðõÓ°/sy¢A£d`ÓEã6¡05Z8DKÓZ¿`(U°Ûœ/-v8`ƒ#0b`ÿŸî÷m·µ×™Ý¡9%úmYÌã¤<:ðÖhmt‡´¿F—¨q¾Mv ?FL1ÌW¤¨¸Ð§«t‹ó—iœ¯œ.±N_°×÷K6´Áà'¡=à<)\vP¸jŒõ*aè È• N “GŽ$퉹Žó,éo ±¨qv\0"»Ü%£&Ú×ÈqI¢ˆnäZœ¿‘ÃùÊ÷!6rïsç¬Êù¬ÊÙ5ÙÓðÑ£+x«¦l˦ž8AÔ8Ѧ-sÙúýBAÛBqÚ/-Îž¤=-“•Ú~eGû‘smö´êÓª_ßy`~Øí¶û¢ßì2‚˜»vúš]‹7³ñªk+3uŠF(všî`ëT±n¿¼ÏËÏî%Ê‹ˆx‡ŽçHQãLX( S¢KåQy¾ç"éê—žqßF”…†ÐÓûÐæÍRœ®Þ[45IÉÒÝ“-Ê(„ë§ë³ô&>¬ ûG¹ÊáÃëfõ±pz›åÅþáØ^Á`³Ä´kt?dkШÍuʺ†ûý+!¥ôéÏ2œßÃ8_=ÉLvñj/mëp´$$?Óºïßwi¾=T>LÒºûˆÛO[‡Ô¶éR¨Žµ5DÔ¸±k]‹ùЇÎL@Ãô45l±ÃjˆëçF _[?V>øùúOØâõ¸uù•ª¨ÃÈ#ˆˆ'ÃtVºËæQؾ_…/E™€Ò lqþÅy[¾éäMÖËU¶I=Ij8”EOÏÍà:Þ,ÕmÕȶü:ÛßååÑú2ÍVÁ!°CÙ1Ü£ƒˆ·»ÉV×x¯›¡¶‹ r ó:§“ÕI>Îݯxª ìÄ©ä}O_{Gûºkt\JiÕ;Fz<Š Qk‡º†r9 ~ ’‡“į…jBз¥ö©j‡¯w«þÁ9“Ê¥àû‚U…}8S!

This documentation is written using the Python LaTeX styles. To format the documentation, get a copy of the Python documentation tools (the Doc/ directory from the Python sources), and create a symlink to the tools/mkhowto script from some convenient bin/ directory. You will need to have a fairly complete set of documentation tools installed on your platform; see http://www.python.org/doc/current/doc/doc.html for more information on the tools.

It is mainly used by the ZODB, though. Note that the data manager API, ``transaction.interfaces.IDataManager``, is syntactically simple, but semantically complex.

The semantics are presented in detail through examples of a sample data manager in ``transaction.tests.test_SampleDataManager``. Changes ======= 1.1.1 (2010-09-16) ------------------ Bug Fixes: - Code in ``_transaction.py`` held on to local references to traceback objects after calling ``sys.exc_info()`` to get one, causing potential reference leakages. - Fixed ``hexlify`` NameError in ``transaction._transaction.oid_repr`` and add test. 1.1.0 (1010-05-12) ------------------ New Features: - Transaction managers and the transaction module can be used with the with statement to define transaction boundaries, as in:: with transaction: ... do some things ... See transaction/tests/convenience.txt for more details. - There is a new iterator function that automates dealing with transient errors (such as ZODB confict errors). For example, in:: for attempt in transaction.attempts(5): with attempt: ... do some things .. If the work being done raises transient errors, the transaction will be retried up to 5 times.

Compatibility issues -------------------- The implementation of Transaction objects involves two layers of backwards compatibility, because this version of transaction supports both ZODB 3 and ZODB 4. Zope is evolving towards the ZODB4 interfaces. Transaction has two methods for a resource manager to call to participate in a transaction -- register() and join(). join() takes a resource manager and adds it to the list of resources. register() is for backwards compatibility. It takes a persistent object and registers its _p_jar attribute. TODO: explain adapter Two-phase commit ---------------- A transaction commit involves an interaction between the transaction object and one or more resource managers. The transaction manager calls the following four methods on each resource manager; it calls tpc_begin() on each resource manager before calling commit() on any of them. 1. tpc_begin(txn) 2. commit(txn) 3. tpc_vote(txn) 4. tpc_finish(txn) Before-commit hook ------------------ Sometimes, applications want to execute some code when a transaction is committed. For example, one might want to delay object indexing until a transaction commits, rather than indexing every time an object is changed. Or someone might want to check invariants only after a set of operations. A pre-commit hook is available for such use cases: use addBeforeCommitHook(), passing it a callable and arguments. The callable will be called with its arguments at the start of the commit (but not for substransaction commits). After-commit hook ------------------ Sometimes, applications want to execute code after a transaction is committed or aborted. For example, one might want to launch non transactional code after a successful commit. Or still someone might want to launch asynchronous code after. A post-commit hook is available for such use cases: use addAfterCommitHook(), passing it a callable and arguments. The callable will be called with a Boolean value representing the status of the commit operation as first argument (true if successfull or false iff aborted) preceding its arguments at the start of the commit (but not for substransaction commits). Error handling -------------- When errors occur during two-phase commit, the transaction manager aborts all the resource managers. The specific methods it calls depend on whether the error occurs before or after the call to tpc_vote() on that transaction manager. If the resource manager has not voted, then the resource manager will have one or more uncommitted objects. There are two cases that lead to this state; either the transaction manager has not called commit() for any objects on this resource manager or the call that failed was a commit() for one of the objects of this resource manager. For each uncommitted object, including the object that failed in its commit(), call abort(). Once uncommitted objects are aborted, tpc_abort() or abort_sub() is called on each resource manager. Synchronization --------------- You can register sychronization objects (synchronizers) with the tranasction manager. The synchronizer must implement beforeCompletion() and afterCompletion() methods. The transaction manager calls beforeCompletion() when it starts a top-level two-phase commit. It calls afterCompletion() when a top-level transaction is committed or aborted. The methods are passed the current Transaction as their only argument.

NameError: name 'xxx' is not defined >>> dm['z'] 3 Retries ------- Commits can fail for transient reasons, especially conflicts. Applications will often retry transactions some number of times to overcome transient failures. This typically looks something like:: for i in range(3): try: with transaction: ... some something ... except SomeTransientException: contine else: break This is rather ugly. Transaction managers provide a helper for this case. To show this, we'll use a contrived example: >>> ntry = 0 >>> with transaction: ... dm['ntry'] = 0 >>> import transaction.interfaces >>> class Retry(transaction.interfaces.TransientError): ... pass >>> for attempt in transaction.manager.attempts(): ... with attempt as t: ... t.note('test') ... print dm['ntry'], ntry ... ntry += 1 ... dm['ntry'] = ntry ... if ntry % 3: ... raise Retry(ntry) 0 0 0 1 0 2 The raising of a subclass of TransientError is critical here. It's what signals that the transaction should be retried. It is generally up to the data manager to signal that a transaction should try again by raising a subclass of TransientError (or TransientError itself, of course). You shouldn't make any assumptions about the object returned by the iterator. (It isn't a transaction or transaction manager, as far as you know. :) If you use the ``as`` keyword in the ``with`` statement, a transaction object will be assigned to the variable named. By default, it tries 3 times. We can tell it how many times to try: >>> for attempt in transaction.manager.attempts(2): ... with attempt: ... ntry += 1 ... if ntry % 3: ... raise Retry(ntry) Traceback (most recent call last): ... Retry: 5 It it doesn't succeed in that many times, the exception will be propagated. Of course, other errors are propagated directly: >>> ntry = 0 >>> for attempt in transaction.manager.attempts(): ... with attempt: ... ntry += 1 ... if ntry == 3: ... raise ValueError(ntry) Traceback (most recent call last): ... ValueError: 3 We can use the default transaction manager: >>> for attempt in transaction.attempts(): ... with attempt as t: ... t.note('test') ... print dm['ntry'], ntry ... ntry += 1 ... dm['ntry'] = ntry ... if ntry % 3: ... raise Retry(ntry) 3 3 3 4 3 5 Sometimes, a data manager doesn't raise exceptions directly, but wraps other other systems that raise exceptions outside of it's control. Data managers can provide a should_retry method that takes an exception instance and returns True if the transaction should be attempted again. >>> class DM(transaction.tests.savepointsample.SampleSavepointDataManager): ... def should_retry(self, e): ... if 'should retry' in str(e): ... return True >>> ntry = 0 >>> dm2 = DM() >>> with transaction: ... dm2['ntry'] = 0 >>> for attempt in transaction.manager.attempts(): ... with attempt: ... print dm['ntry'], ntry ... ntry += 1 ... dm['ntry'] = ntry ... dm2['ntry'] = ntry ... if ntry % 3: ... raise ValueError('we really should retry this') 6 0 6 1 6 2 >>> dm2['ntry'] 3 zope2.13-2.13.21/source/transaction/transaction/tests/test_weakset.py0000644000175000017500000000434412214017513024530 0ustar arnauarnau############################################################################## # # Copyright (c) 2007 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

Applications ------------ To demonstrate how savepoints work with transactions, we've provided a sample data manager implementation that provides savepoint support. The primary purpose of this data manager is to provide code that can be read to understand how savepoints work. The secondary purpose is to provide support for demonstrating the correct operation of savepoint support within the transaction system. This data manager is very simple. It provides flat storage of named immutable values, like strings and numbers. >>> import transaction >>> from transaction.tests import savepointsample >>> dm = savepointsample.SampleSavepointDataManager() >>> dm['name'] = 'bob' As with other data managers, we can commit changes: >>> transaction.commit() >>> dm['name'] 'bob' and abort changes: >>> dm['name'] = 'sally' >>> dm['name'] 'sally' >>> transaction.abort() >>> dm['name'] 'bob' Now, let's look at an application that manages funds for people. It allows deposits and debits to be entered for multiple people. It accepts a sequence of entries and generates a sequence of status messages. For each entry, it applies the change and then validates the user's account. If the user's account is invalid, we roll back the change for that entry. The success or failure of an entry is indicated in the output status. First we'll initialize some accounts: >>> dm['bob-balance'] = 0.0 >>> dm['bob-credit'] = 0.0 >>> dm['sally-balance'] = 0.0 >>> dm['sally-credit'] = 100.0 >>> transaction.commit() Now, we'll define a validation function to validate an account: >>> def validate_account(name): ... if dm[name+'-balance'] + dm[name+'-credit'] < 0: ... raise ValueError('Overdrawn', name) And a function to apply entries. If the function fails in some unexpected way, it rolls back all of its changes and prints the error: >>> def apply_entries(entries): ... savepoint = transaction.savepoint() ... try: ... for name, amount in entries: ... entry_savepoint = transaction.savepoint() ... try: ... dm[name+'-balance'] += amount ... validate_account(name) ... except ValueError, error: ... entry_savepoint.rollback() ... print 'Error', str(error) ... else: ... print 'Updated', name ... except Exception, error: ... savepoint.rollback() ... print 'Unexpected exception', error Now let's try applying some entries: >>> apply_entries([ ... ('bob', 10.0), ... ('sally', 10.0), ... ('bob', 20.0), ... ('sally', 10.0), ... ('bob', -100.0), ... ('sally', -100.0), ... ]) Updated bob Updated sally Updated bob Updated sally Error ('Overdrawn', 'bob') Updated sally >>> dm['bob-balance'] 30.0 >>> dm['sally-balance'] -80.0 If we provide entries that cause an unexpected error: >>> apply_entries([ ... ('bob', 10.0), ... ('sally', 10.0), ... ('bob', '20.0'), ... ('sally', 10.0), ... ]) Updated bob Updated sally Unexpected exception unsupported operand type(s) for +=: 'float' and 'str' Because the apply_entries used a savepoint for the entire function, it was able to rollback the partial changes without rolling back changes made in the previous call to ``apply_entries``: >>> dm['bob-balance'] 30.0 >>> dm['sally-balance'] -80.0 If we now abort the outer transactions, the earlier changes will go away: >>> transaction.abort() >>> dm['bob-balance'] 0.0 >>> dm['sally-balance'] 0.0 Savepoint invalidation ---------------------- A savepoint can be used any number of times: >>> dm['bob-balance'] = 100.0 >>> dm['bob-balance'] 100.0 >>> savepoint = transaction.savepoint() >>> dm['bob-balance'] = 200.0 >>> dm['bob-balance'] 200.0 >>> savepoint.rollback() >>> dm['bob-balance'] 100.0 >>> savepoint.rollback() # redundant, but should be harmless >>> dm['bob-balance'] 100.0 >>> dm['bob-balance'] = 300.0 >>> dm['bob-balance'] 300.0 >>> savepoint.rollback() >>> dm['bob-balance'] 100.0 However, using a savepoint invalidates any savepoints that come after it: >>> dm['bob-balance'] = 200.0 >>> dm['bob-balance'] 200.0 >>> savepoint1 = transaction.savepoint() >>> dm['bob-balance'] = 300.0 >>> dm['bob-balance'] 300.0 >>> savepoint2 = transaction.savepoint() >>> savepoint.rollback() >>> dm['bob-balance'] 100.0 >>> savepoint2.rollback() Traceback (most recent call last): ... InvalidSavepointRollbackError >>> savepoint1.rollback() Traceback (most recent call last): ... InvalidSavepointRollbackError >>> transaction.abort() Databases without savepoint support ----------------------------------- Normally it's an error to use savepoints with databases that don't support savepoints: >>> dm_no_sp = savepointsample.SampleDataManager() >>> dm_no_sp['name'] = 'bob' >>> transaction.commit() >>> dm_no_sp['name'] = 'sally' >>> savepoint = transaction.savepoint() Traceback (most recent call last): ... TypeError: ('Savepoints unsupported', {'name': 'bob'}) >>> transaction.abort() However, a flag can be passed to the transaction savepoint method to indicate that databases without savepoint support should be tolerated until a savepoint is rolled back. This allows transactions to proceed if there are no reasons to roll back: >>> dm_no_sp['name'] = 'sally' >>> savepoint = transaction.savepoint(1) >>> dm_no_sp['name'] = 'sue' >>> transaction.commit() >>> dm_no_sp['name'] 'sue' >>> dm_no_sp['name'] = 'sam' >>> savepoint = transaction.savepoint(1) >>> savepoint.rollback() Traceback (most recent call last): ... TypeError: ('Savepoints unsupported', {'name': 'sam'}) Failures -------- If a failure occurs when creating or rolling back a savepoint, the transaction state will be uncertain and the transaction will become uncommitable. From that point on, most transaction operations, including commit, will fail until the transaction is aborted. In the previous example, we got an error when we tried to rollback the savepoint. If we try to commit the transaction, the commit will fail: >>> transaction.commit() # doctest: +ELLIPSIS Traceback (most recent call last): ...

Doom is useful in places where abort is unsafe and an exception cannot be raised. This occurs when the programmer wants the code following the doom to run but not commit. It is unsafe to abort in these circumstances as a following get() may implicitly open a new transaction. Any attempt to commit a doomed transaction will raise a DoomedTransaction exception. An example of such a use case can be found in zope/app/form/browser/editview.py. Here a form validation failure must doom the transaction as committing the transaction may have side-effects. However, the form code must continue to calculate a form containing the error messages to return. For Zope in general, code running within a request should always doom transactions rather than aborting them. It is the responsibilty of the publication to either abort() or commit() the transaction. Application code can use savepoints and doom() safely. To see how it works we first need to create a stub data manager: >>> from transaction.interfaces import IDataManager >>> from zope.interface import implements >>> class DataManager: ... implements(IDataManager) ... def __init__(self): ... self.attr_counter = {} ... def __getattr__(self, name): ... def f(transaction): ... self.attr_counter[name] = self.attr_counter.get(name, 0) + 1 ... return f ... def total(self): ... count = 0 ... for access_count in self.attr_counter.values(): ... count += access_count ... return count ... def sortKey(self): ... return 1 Start a new transaction: >>> import transaction >>> txn = transaction.begin() >>> dm = DataManager() >>> txn.join(dm) We can ask a transaction if it is doomed to avoid expensive operations. An example of a use case is an object-relational mapper where a pre-commit hook sends all outstanding SQL to a relational database for objects changed during the transaction. This expensive operation is not necessary if the transaction has been doomed. A non-doomed transaction should return False: >>> txn.isDoomed() False We can doom a transaction by calling .doom() on it: >>> txn.doom() >>> txn.isDoomed() True We can doom it again if we like: >>> txn.doom() The data manager is unchanged at this point: >>> dm.total() 0 Attempting to commit a doomed transaction any number of times raises a DoomedTransaction: >>> txn.commit() # doctest: +ELLIPSIS Traceback (most recent call last): ... DoomedTransaction >>> txn.commit() # doctest: +ELLIPSIS Traceback (most recent call last): ... DoomedTransaction But still leaves the data manager unchanged: >>> dm.total() 0 But the doomed transaction can be aborted: >>> txn.abort() Which aborts the data manager: >>> dm.total() 1 >>> dm.attr_counter['abort'] 1 Dooming the current transaction can also be done directly from the transaction module. We can also begin a new transaction directly after dooming the old one: >>> txn = transaction.begin() >>> transaction.isDoomed() False >>> transaction.doom() >>> transaction.isDoomed() True >>> txn = transaction.begin() After committing a transaction we get an assertion error if we try to doom the transaction. This could be made more specific, but trying to doom a transaction after it's been committed is probably a programming error: >>> txn = transaction.begin() >>> txn.commit() >>> txn.doom() Traceback (most recent call last): ... AssertionError A doomed transaction should act the same as an active transaction, so we should be able to join it: >>> txn = transaction.begin() >>> txn.doom() >>> dm2 = DataManager() >>> txn.join(dm2) Clean up: >>> txn = transaction.begin() >>> txn.abort() zope2.13-2.13.21/source/transaction/transaction/tests/test_transaction.py0000644000175000017500000005232512214017513025414 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002, 2005 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

I wrote these unittests to investigate some odd transaction behavior when doing unittests of integrating non sub transaction aware objects, and to insure proper txn behavior. these tests test the transaction system independent of the rest of the zodb. you can see the method calls to a jar by passing the keyword arg tracing to the modify method of a dataobject. the value of the arg is a prefix used for tracing print calls to that objects jar. the number of times a jar method was called can be inspected by looking at an attribute of the jar that is the method name prefixed with a c (count/check). i've included some tracing examples for tests that i thought were illuminating as doc strings below. TODO add in tests for objects which are modified multiple times, for example an object that gets modified in multiple sub txns.

The transaction package supports several different APIs for resource managers. The original ZODB3 API was implemented by ZODB.Connection. The Connection passed persistent objects to a Transaction's register() method. It's possible that third-party code also used this API, hence these tests that the code that adapts the old interface to the current API works. These tests use a TestConnection object that implements the old API. They check that the right methods are called and in roughly the right order. Common cases ------------ First, check that a basic transaction commit works. >>> cn = TestConnection() >>> cn.register(Object()) >>> cn.register(Object()) >>> cn.register(Object()) >>> transaction.commit() >>> len(cn.committed) 3 >>> len(cn.aborted) 0 >>> cn.calls ['begin', 'vote', 'finish'] Second, check that a basic transaction abort works. If the application calls abort(), then the transaction never gets into the two-phase commit. It just aborts each object. >>> cn = TestConnection() >>> cn.register(Object()) >>> cn.register(Object()) >>> cn.register(Object()) >>> transaction.abort() >>> len(cn.committed) 0 >>> len(cn.aborted) 3 >>> cn.calls [] Error handling -------------- The tricky part of the implementation is recovering from an error that occurs during the two-phase commit. We override the commit() and abort() methods of Object to cause errors during commit. Note that the implementation uses lists internally, so that objects are committed in the order they are registered. (In the presence of multiple resource managers, objects from a single resource manager are committed in order. I'm not sure if this is an accident of the implementation or a feature that should be supported by any implementation.) The order of resource managers depends on sortKey(). >>> cn = TestConnection() >>> cn.register(Object()) >>> cn.register(CommitError()) >>> cn.register(Object()) >>> transaction.commit() Traceback (most recent call last): ...

It is mainly used by the ZODB, though. Note that the data manager API, ``transaction.interfaces.IDataManager``, is syntactically simple, but semantically complex. The semantics were not easy to express in the interface. This could probably use more work.

See transaction/tests/convenience.txt for more details. - There is a new iterator function that automates dealing with transient errors (such as ZODB confict errors). For example, in:: for attempt in transaction.attempts(5): with attempt: ... do some things .. If the work being done raises transient errors, the transaction will be retried up to 5 times. See transaction/tests/convenience.txt for more details. Bugs fixed: - Fixed a bug that caused extra commit calls to be made on data managers under certain special circumstances. https://mail.zope.org/pipermail/zodb-dev/2010-May/013329.html - When threads were reused, transaction data could leak accross them, causing subtle application bugs. https://bugs.launchpad.net/zodb/+bug/239086 1.0.1 (2010-05-07) ------------------ - LP #142464: remove double newline between log entries: it makes doing smarter formatting harder. - Updated tests to remove use of deprecated ``zope.testing.doctest``. 1.0.0 (2009-07-24) ------------------ - Fix test that incorrectly relied on the order of a list that was generated from a dict. - Remove crufty DEPENDENCIES.cfg left over from zpkg. 1.0a1 (2007-12-18) ------------------ = Initial release, branched from ZODB trunk on 2007-11-08 (aka "3.9.0dev"). - Remove (deprecated) support for beforeCommitHook alias to addBeforeCommitHook. - Add weakset tests. - Remove unit tests that depend on ZODB.tests.utils from test_transaction (these are actually integration tests). zope2.13-2.13.21/source/transaction/ez_setup.pyc0000644000175000017500000002140012214017513020330 0ustar arnauarnauó K0Rc@s²dZddlZdZdejd Zidd6dd 6d d 6d d 6dd6dd6dd6dd6dd6dd6dd6dd6dd6d d!6d"d#6d$d%6d&d'6d(d)6d*d+6d,d-6d.d/6d0d16d2d36d4d56d6d76d8d96d:d;6ZddlZddlZd<„Zeeejd=d>„Z eeejd=d?„Z ed@„Z dA„Z e dBkr®eejƒdCkršejdDdEkrše ejdCƒq®e ejdDƒndS(Fs Bootstrap setuptools installation If you want to use setuptools in your package's setup.py, just include this file in the same directory with it, and add this to the top of your setup.py:: from ez_setup import use_setuptools use_setuptools() If you want to require a specific version of setuptools, set a download mirror, or use an alternate download directory, you can do so by supplying the appropriate options to ``use_setuptools()``.

We express these constraints in interfaces. Let's define some container and item interfaces: >>> from zope.container.interfaces import IContainer >>> from zope.location.interfaces import IContained >>> from zope.container.constraints import containers, contains >>> class IBuddyFolder(IContainer): ... contains('.IBuddy') In this example, we used the contains function to declare that objects that provide IBuddyFolder can only contain items that provide IBuddy. Note that we used a string containing a dotted name for the IBuddy interface. This is because IBuddy hasn't been defined yet. When we define IBuddy, we can use IBuddyFolder directly: >>> class IBuddy(IContained): ... containers(IBuddyFolder) Now, with these interfaces in place, we can define Buddy and BuddyFolder classes and verify that we can put buddies in buddy folders: >>> from zope import interface >>> class Buddy: ... interface.implements(IBuddy) >>> class BuddyFolder: ... interface.implements(IBuddyFolder) >>> from zope.container.constraints import checkObject, checkFactory >>> from zope.component.factory import Factory >>> checkObject(BuddyFolder(), 'x', Buddy()) >>> checkFactory(BuddyFolder(), 'x', Factory(Buddy)) True If we try to use other containers or folders, we'll get errors: >>> class Container: ... interface.implements(IContainer) >>> class Contained: ... interface.implements(IContained) >>> checkObject(Container(), 'x', Buddy()) ... # doctest: +ELLIPSIS Traceback (most recent call last): InvalidContainerType: ... >>> checkFactory(Container(), 'x', Factory(Buddy)) False >>> checkObject(BuddyFolder(), 'x', Contained()) ... # doctest: +ELLIPSIS Traceback (most recent call last): InvalidItemType: ... >>> checkFactory(BuddyFolder(), 'x', Factory(Contained)) False In the example, we defined the container first and then the items. We could have defined these in the opposite order: >>> class IContact(IContained): ... containers('.IContacts') >>> class IContacts(IContainer): ... contains(IContact) >>> class Contact: ... interface.implements(IContact) >>> class Contacts: ... interface.implements(IContacts) >>> checkObject(Contacts(), 'x', Contact()) >>> checkFactory(Contacts(), 'x', Factory(Contact)) True >>> checkObject(Contacts(), 'x', Buddy()) ... # doctest: +ELLIPSIS Traceback (most recent call last): InvalidItemType: ... >>> checkFactory(Contacts(), 'x', Factory(Buddy)) False ======= CHANGES ======= 3.11.2 (2010-09-25) ------------------- - Added not declared, but needed test dependency on `zope.testing`. 3.11.1 (2010-04-30) ------------------- - Prefer the standard libraries doctest module to the one from zope.testing. - Added compatibility with ZODB3 3.10 by importing the IBroken interface from it directly. Once we can rely on the new ZODB3 version exclusively, we can remove the dependency onto the zope.broken distribution. - Never fail if the suggested name is in a wrong type (#227617) - ``checkName`` first checks the parameter type before the emptiness. 3.11.0 (2009-12-31) ------------------- - Copy two trivial classes from zope.cachedescriptors into this package, which allows us to remove that dependency. We didn't actually use any caching properties as the dependency suggested. 3.10.1 (2009-12-29) ------------------- - Moved zope.copypastemove related tests into that package. - Removed no longer used zcml prefix from the configure file. - Stop importing DocTestSuite from zope.testing.doctestunit. Fixes compatibility problems with zope.testing 3.8.4. 3.10.0 (2009-12-15) ------------------- - Break testing dependency on zope.app.testing. - Break testing dependency on zope.app.dependable by moving the code and tests into that package. - Import ISite from zope.component after it was moved there from zope.location. 3.9.1 (2009-10-18) ------------------ - Rerelease 3.9.0 as it had a broken Windows 2.6 egg. - Marked as part of the ZTK. 3.9.0 (2009-08-28) ------------------ - Previous releases should be versioned 3.9.0 as they are not pure bugfix releases and worth a "feature" release, increasing feature version. Packages that depend on any changes introduced in version 3.8.2 or 3.8.3 should depend on version 3.9 or greater. 3.8.3 (2009-08-27) ------------------ - Move IXMLRPCPublisher ZCML registrations for containers from zope.app.publisher.xmlrpc to zope.container for now. 3.8.2 (2009-05-17) ------------------ - Rid ourselves of ``IContained`` interface. This interface was moved to ``zope.location.interfaces``. A b/w compat import still exists to keep old code running. Depend on ``zope.location``>=3.5.4. - Rid ourselves of the implementations of ``IObjectMovedEvent``, ``IObjectAddedEvent``, ``IObjectRemovedEvent`` interfaces and ``ObjectMovedEvent``, ``ObjectAddedEvent`` and ``ObjectRemovedEvent`` classes. B/w compat imports still exist. All of these were moved to ``zope.lifecycleevent``. Depend on ``zope.lifecycleevent``>=3.5.2. - Fix a bug in OrderedContainer where trying to set the value for a key that already exists (duplication error) would actually delete the key from the order, leaving a dangling reference. - Partially break dependency on ``zope.traversing`` by disusing zope.traversing.api.getPath in favor of using ILocationInfo(object).getPath(). The rest of the runtime dependencies on zope.traversing are currently interface dependencies. - Break runtime dependency on ``zope.app.dependable`` by using a zcml condition on the qsubscriber ZCML directive that registers the CheckDependency handler for IObjectRemovedEvent. If ``zope.app.dependable`` is not installed, this subscriber will never be registered. ``zope.app.dependable`` is now a testing dependency only. 3.8.1 (2009-04-03) ------------------ - Fixed misspackaged 3.8.0 3.8.0 (2009-04-03) ------------------ - Change configure.zcml to not depend on zope.app.component. Fixes: https://bugs.launchpad.net/bugs/348329 - Moved the declaration of ``IOrderedContainer.updateOrder`` to a new, basic ``IOrdered`` interface and let ``IOrderedContainer`` inherit it. This allows easier reuse of the declaration. 3.7.2 (2009-03-12) ------------------ - Fix: added missing ComponentLookupError, missing since revision 95429 and missing in last release. - Adapt to the move of IDefaultViewName from zope.component.interfaces to zope.publisher.interfaces. - Add support for reserved names for containers. To specify reserved names for some container, you need to provide an adapter from the container to the ``zope.container.interfaces.IReservedNames`` interface. The default NameChooser is now also aware of reserved names. 3.7.1 (2009-02-05) ------------------ - Raise more "Pythonic" errors from ``__setitem__``, losing the dependency on ``zope.exceptions``: o ``zope.exceptions.DuplicationError`` -> ``KeyError`` o ``zope.exceptions.UserError`` -> ``ValueError`` - Moved import of ``IBroken`` interface to use new ``zope.broken`` package, which has no dependencies beyond ``zope.interface``. - Made ``test`` part pull in the extra test requirements of this package. - Split the ``z3c.recipe.compattest`` configuration out into a new file, ``compat.cfg``, to reduce the burden of doing standard unit tests. - Stripped out bogus develop eggs from ``buildout.cfg``. 3.7.0 (2009-01-31) ------------------ - Split this package off ``zope.app.container``. This package is intended to have far less dependencies than ``zope.app.container``. - This package also contains the container implementation that used to be in ``zope.app.folder``.

In this state, the _p_changed attribute is non-None and false and the _p_jar attribute is set to a data manager. - Sticky This state is identical to the saved state except that the object cannot transition to the ghost state. This is a special state used by C methods of persistent objects to make sure that state is not unloaded in the middle of computation. In this state, the _p_changed attribute is non-None and false and the _p_jar attribute is set to a data manager. There is no Python API for detecting whether an object is in the sticky state. - Changed The object has been changed. In this state, the _p_changed attribute is true and the _p_jar attribute is set to a data manager. - Ghost the object is in memory but its state has not been loaded from the database (or its state has been unloaded). In this state, the object doesn't contain any application data. In this state, the _p_changed attribute is None, and the _p_jar attribute is set to the data manager from which the object was obtained. In all the above, _p_oid (the persistent object id) is set when _p_jar first gets set. The following state transitions are possible: - Unsaved -> Saved This transition occurs when an object is saved in the database. This usually happens when an unsaved object is added to (e.g. as an attribute or item of) a saved (or changed) object and the transaction is committed. - Saved -> Changed Sticky -> Changed Ghost -> Changed This transition occurs when someone sets an attribute or sets _p_changed to a true value on a saved, sticky or ghost object. When the transition occurs, the persistent object is required to call the register() method on its data manager, passing itself as the only argument. Prior to ZODB 3.6, setting _p_changed to a true value on a ghost object was ignored (the object remained a ghost, and getting its _p_changed attribute continued to return None). - Saved -> Sticky This transition occurs when C code marks the object as sticky to prevent its deactivation. - Saved -> Ghost This transition occurs when a saved object is deactivated or invalidated. See discussion below. - Sticky -> Saved This transition occurs when C code unmarks the object as sticky to allow its deactivation. - Changed -> Saved This transition occurs when a transaction is committed. After saving the state of a changed object during transaction commit, the data manager sets the object's _p_changed to a non-None false value. - Changed -> Ghost This transition occurs when a transaction is aborted. All changed objects are invalidated by the data manager by an abort. - Ghost -> Saved This transition occurs when an attribute or operation of a ghost is accessed and the object's state is loaded from the database. Note that there is a separate C API that is not included here. The C API requires a specific data layout and defines the sticky state. About Invalidation, Deactivation and the Sticky & Ghost States The sticky state is intended to be a short-lived state, to prevent an object's state from being discarded while we're in C routines. It is an error to invalidate an object in the sticky state. Deactivation is a request that an object discard its state (become a ghost). Deactivation is an optimization, and a request to deactivate may be ignored. There are two equivalent ways to request deactivation: - call _p_deactivate() - set _p_changed to None There are two ways to invalidate an object: call the _p_invalidate() method (preferred) or delete its _p_changed attribute. This cannot be ignored, and is used when semantics require invalidation. Normally, an invalidated object transitions to the ghost state. However, some objects cannot be ghosts. When these objects are invalidated, they immediately reload their state from their data manager, and are then in the saved state. """ _p_jar = Attribute( """The data manager for the object.

At and after ZODB 3.6, setting _p_changed to a true value for a ghost object activates the object; prior to 3.6, setting _p_changed to a true value on a ghost object was ignored. Note that an object can transition to the changed state only if it has a data manager.

They are stored in the self->data dictionary, and are never garbage collected. The klass_items() method returns a sequence of (oid,object) tuples for every Persistent Class, which should make it possible to implement garbage collection in Python if necessary. Regime 2: Ghost Objects There is no benefit to keeping a ghost object which has no external references, therefore a weak reference scheme is used to ensure that ghost objects are removed from memory as soon as possible, when the last external reference is lost. Ghost objects are stored in the self->data dictionary. Normally a dictionary keeps a strong reference on its values, however this reference count is 'stolen'. This weak reference scheme leaves a dangling reference, in the dictionary, when the last external reference is lost. To clean up this dangling reference the persistent object dealloc function calls self->cache->_oid_unreferenced(self->oid). The cache looks up the oid in the dictionary, ensures it points to an object whose reference count is zero, then removes it from the dictionary. Before removing the object from the dictionary it must temporarily resurrect the object in much the same way that class instances are resurrected before their __del__ is called. Since ghost objects are stored under a different regime to non-ghost objects, an extra ghostify function in cPersistenceAPI replaces self->state=GHOST_STATE assignments that were common in other persistent classes (such as BTrees). Regime 3: Non-Ghost Objects Non-ghost objects are stored in two data structures: the dictionary mapping oids to objects and a doubly-linked list that encodes the order in which the objects were accessed. The dictionary reference is borrowed, as it is for ghosts. The list reference is a new reference; the list stores recently used objects, even if they are otherwise unreferenced, to avoid loading the object from the database again. The doubly-link-list nodes contain next and previous pointers linking together the cache and all non-ghost persistent objects. The node embedded in the cache is the home position. On every attribute access a non-ghost object will relink itself just behind the home position in the ring. Objects accessed least recently will eventually find themselves positioned after the home position. Occasionally other nodes are temporarily inserted in the ring as position markers. The cache contains a ring_lock flag which must be set and unset before and after doing so. Only if the flag is unset can the cache assume that all nodes are either his own home node, or nodes from persistent objects. This assumption is useful during the garbage collection process. The number of non-ghost objects is counted in self->non_ghost_count. The garbage collection process consists of traversing the ring, and deactivating (that is, turning into a ghost) every object until self->non_ghost_count is down to the target size, or until it reaches the home position again. Note that objects in the sticky or changed states are still kept in the ring, however they can not be deactivated. The garbage collection process must skip such objects, rather than deactivating them. */ static char cPickleCache_doc_string[] = "Defines the PickleCache used by ZODB Connection objects.\n" "\n" "$Id: cPickleCache.c 29896 2005-04-07 04:48:06Z tim_one $\n"; #define DONT_USE_CPERSISTENCECAPI #include "cPersistence.h" #include "structmember.h" #include #include #undef Py_FindMethod /* Python string objects to speed lookups; set by module init. */ static PyObject *py__p_changed; static PyObject *py__p_deactivate; static PyObject *py__p_jar; static PyObject *py__p_oid; static cPersistenceCAPIstruct *capi; /* This object is the pickle cache.

That's the key difference between deactivation and invalidation. >>> p._p_invalidate() >>> p._p_state -1 Now that the object is a ghost, any attempt to modify it will require that it be unghosted first. The test data manager has the odd property that it sets the object's ``x`` attribute to ``42`` when it is unghosted. >>> p.inc() >>> p.x 43 >>> dm.called 2 You can manually reset the changed field to ``False``, although it's not clear why you would want to do that. The object changes to the ``UPTODATE`` state but retains its modifications. >>> p._p_changed = False >>> p._p_state 0 >>> p._p_changed False >>> p.x 43 >>> p.inc() >>> p._p_changed True >>> dm.called 3 ``__getstate__()`` and ``__setstate__()`` ----------------------------------------- The next several tests cover the ``__getstate__()`` and ``__setstate__()`` implementations. >>> p = P() >>> state = p.__getstate__() >>> isinstance(state, dict) True >>> state['x'] 0 >>> p._p_state 0 Calling setstate always leaves the object in the uptodate state? (I'm not entirely clear on this one.) >>> p.__setstate__({'x': 5}) >>> p._p_state 0 Assigning to a volatile attribute has no effect on the object state. >>> p._v_foo = 2 >>> p.__getstate__() {'x': 5} >>> p._p_state 0 The ``_p_serial`` attribute is not affected by calling setstate. >>> p._p_serial = "00000012" >>> p.__setstate__(p.__getstate__()) >>> p._p_serial '00000012' Change Ghost test ----------------- If an object is a ghost and its ``_p_changed`` is set to ``True`` (any true value), it should activate (unghostify) the object. This behavior is new in ZODB 3.6; before then, an attempt to do ``ghost._p_changed = True`` was ignored. >>> p = P() >>> p._p_jar = DM() >>> p._p_oid = 1 >>> p._p_deactivate() >>> p._p_changed # None >>> p._p_state # ghost state -1 >>> p._p_changed = True >>> p._p_changed 1 >>> p._p_state # changed state 1 >>> p.x 42 Activate, deactivate, and invalidate ------------------------------------ Some of these tests are redundant, but are included to make sure there are explicit and simple tests of ``_p_activate()``, ``_p_deactivate()``, and ``_p_invalidate()``. >>> p = P() >>> p._p_oid = 1 >>> p._p_jar = DM() >>> p._p_deactivate() >>> p._p_state -1 >>> p._p_activate() >>> p._p_state 0 >>> p.x 42 >>> p.inc() >>> p.x 43 >>> p._p_state 1 >>> p._p_invalidate() >>> p._p_state -1 >>> p.x 42 Test failures ------------- The following tests cover various errors cases. When an object is modified, it registers with its data manager. If that registration fails, the exception is propagated and the object stays in the up-to-date state. It shouldn't change to the modified state, because it won't be saved when the transaction commits. >>> p = P() >>> p._p_oid = 1 >>> p._p_jar = BrokenDM() >>> p._p_state 0 >>> p._p_jar.called 0 >>> p._p_changed = 1 Traceback (most recent call last): ... NotImplementedError >>> p._p_jar.called 1 >>> p._p_state 0 Make sure that exceptions that occur inside the data manager's ``setstate()`` method propagate out to the caller. >>> p = P() >>> p._p_oid = 1 >>> p._p_jar = BrokenDM() >>> p._p_deactivate() >>> p._p_state -1 >>> p._p_activate() Traceback (most recent call last): ... NotImplementedError >>> p._p_state -1 Special test to cover layout of ``__dict__`` -------------------------------------------- We once had a bug in the `Persistent` class that calculated an incorrect offset for the ``__dict__`` attribute. It assigned ``__dict__`` and ``_p_jar`` to the same location in memory. This is a simple test to make sure they have different locations. >>> p = P() >>> p.inc() >>> p.inc() >>> 'x' in p.__dict__ True >>> p._p_jar Inheritance and metaclasses --------------------------- Simple tests to make sure it's possible to inherit from the `Persistent` base class multiple times. There used to be metaclasses involved in `Persistent` that probably made this a more interesting test. >>> class A(Persistent): ... pass >>> class B(Persistent): ... pass >>> class C(A, B): ... pass >>> class D(object): ... pass >>> class E(D, B): ... pass >>> a = A() >>> b = B() >>> c = C() >>> d = D() >>> e = E() Also make sure that it's possible to define `Persistent` classes that have a custom metaclass. >>> class alternateMeta(type): ... type >>> class alternate(object): ... __metaclass__ = alternateMeta >>> class mixedMeta(alternateMeta, type): ... pass >>> class mixed(alternate, Persistent): ... pass >>> class mixed(Persistent, alternate): ... pass Basic type structure -------------------- >>> Persistent.__dictoffset__ 0 >>> Persistent.__weakrefoffset__ 0 >>> Persistent.__basicsize__ > object.__basicsize__ True >>> P.__dictoffset__ > 0 True >>> P.__weakrefoffset__ > 0 True >>> P.__dictoffset__ < P.__weakrefoffset__ True >>> P.__basicsize__ > Persistent.__basicsize__ True Slots ----- These are some simple tests of classes that have an ``__slots__`` attribute. Some of the classes should have slots, others shouldn't. >>> class noDict(object): ... __slots__ = ['foo'] >>> class p_noDict(Persistent): ... __slots__ = ['foo'] >>> class p_shouldHaveDict(p_noDict): ... pass >>> p_noDict.__dictoffset__ 0 >>> x = p_noDict() >>> x.foo = 1 >>> x.foo 1 >>> x.bar = 1 Traceback (most recent call last): ... AttributeError: 'p_noDict' object has no attribute 'bar' >>> x._v_bar = 1 Traceback (most recent call last): ... AttributeError: 'p_noDict' object has no attribute '_v_bar' >>> x.__dict__ Traceback (most recent call last): ... AttributeError: 'p_noDict' object has no attribute '__dict__' The various _p_ attributes are unaffected by slots. >>> p._p_oid >>> p._p_jar >>> p._p_state 0 If the most-derived class does not specify >>> p_shouldHaveDict.__dictoffset__ > 0 True >>> x = p_shouldHaveDict() >>> isinstance(x.__dict__, dict) True Pickling -------- There's actually a substantial effort involved in making subclasses of `Persistent` work with plain-old pickle. The ZODB serialization layer never calls pickle on an object; it pickles the object's class description and its state as two separate pickles. >>> import pickle >>> p = P() >>> p.inc() >>> p2 = pickle.loads(pickle.dumps(p)) >>> p2.__class__ is P True >>> p2.x == p.x True We should also test that pickle works with custom getstate and setstate. Perhaps even reduce. The problem is that pickling depends on finding the class in a particular module, and classes defined here won't appear in any module. We could require each user of the tests to define a base class, but that might be tedious. Interfaces ---------- Some versions of Zope and ZODB have the `zope.interfaces` package available. If it is available, then persistent will be associated with several interfaces. It's hard to write a doctest test that runs the tests only if `zope.interface` is available, so this test looks a little unusual. One problem is that the assert statements won't do anything if you run with `-O`. >>> try: ... import zope.interface ... except ImportError: ... pass ... else: ... from persistent.interfaces import IPersistent ... assert IPersistent.implementedBy(Persistent) ... p = Persistent() ... assert IPersistent.providedBy(p) ... assert IPersistent.implementedBy(P) ... p = P() ... assert IPersistent.providedBy(p) zope2.13-2.13.21/source/zope.container/include/persistent/tests/test_overriding_attrs.py0000644000175000017500000002600712214017546030367 0ustar arnauarnau############################################################################## # # Copyright (c) 2004 Zope Corporation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

Once we can rely on the new ZODB3 version exclusively, we can remove the dependency onto the zope.broken distribution. - Never fail if the suggested name is in a wrong type (#227617) - ``checkName`` first checks the parameter type before the emptiness. 3.11.0 (2009-12-31) ------------------- - Copy two trivial classes from zope.cachedescriptors into this package, which allows us to remove that dependency. We didn't actually use any caching properties as the dependency suggested. 3.10.1 (2009-12-29) ------------------- - Moved zope.copypastemove related tests into that package. - Removed no longer used zcml prefix from the configure file. - Stop importing DocTestSuite from zope.testing.doctestunit. Fixes compatibility problems with zope.testing 3.8.4. 3.10.0 (2009-12-15) ------------------- - Break testing dependency on zope.app.testing. - Break testing dependency on zope.app.dependable by moving the code and tests into that package. - Import ISite from zope.component after it was moved there from zope.location. 3.9.1 (2009-10-18) ------------------ - Rerelease 3.9.0 as it had a broken Windows 2.6 egg. - Marked as part of the ZTK. 3.9.0 (2009-08-28) ------------------ - Previous releases should be versioned 3.9.0 as they are not pure bugfix releases and worth a "feature" release, increasing feature version. Packages that depend on any changes introduced in version 3.8.2 or 3.8.3 should depend on version 3.9 or greater. 3.8.3 (2009-08-27) ------------------ - Move IXMLRPCPublisher ZCML registrations for containers from zope.app.publisher.xmlrpc to zope.container for now. 3.8.2 (2009-05-17) ------------------ - Rid ourselves of ``IContained`` interface. This interface was moved to ``zope.location.interfaces``. A b/w compat import still exists to keep old code running. Depend on ``zope.location``>=3.5.4. - Rid ourselves of the implementations of ``IObjectMovedEvent``, ``IObjectAddedEvent``, ``IObjectRemovedEvent`` interfaces and ``ObjectMovedEvent``, ``ObjectAddedEvent`` and ``ObjectRemovedEvent`` classes. B/w compat imports still exist. All of these were moved to ``zope.lifecycleevent``. Depend on ``zope.lifecycleevent``>=3.5.2. - Fix a bug in OrderedContainer where trying to set the value for a key that already exists (duplication error) would actually delete the key from the order, leaving a dangling reference. - Partially break dependency on ``zope.traversing`` by disusing zope.traversing.api.getPath in favor of using ILocationInfo(object).getPath(). The rest of the runtime dependencies on zope.traversing are currently interface dependencies. - Break runtime dependency on ``zope.app.dependable`` by using a zcml condition on the qsubscriber ZCML directive that registers the CheckDependency handler for IObjectRemovedEvent. If ``zope.app.dependable`` is not installed, this subscriber will never be registered. ``zope.app.dependable`` is now a testing dependency only. 3.8.1 (2009-04-03) ------------------ - Fixed misspackaged 3.8.0 3.8.0 (2009-04-03) ------------------ - Change configure.zcml to not depend on zope.app.component. Fixes: https://bugs.launchpad.net/bugs/348329 - Moved the declaration of ``IOrderedContainer.updateOrder`` to a new, basic ``IOrdered`` interface and let ``IOrderedContainer`` inherit it. This allows easier reuse of the declaration. 3.7.2 (2009-03-12) ------------------ - Fix: added missing ComponentLookupError, missing since revision 95429 and missing in last release. - Adapt to the move of IDefaultViewName from zope.component.interfaces to zope.publisher.interfaces. - Add support for reserved names for containers. To specify reserved names for some container, you need to provide an adapter from the container to the ``zope.container.interfaces.IReservedNames`` interface. The default NameChooser is now also aware of reserved names. 3.7.1 (2009-02-05) ------------------ - Raise more "Pythonic" errors from ``__setitem__``, losing the dependency on ``zope.exceptions``: o ``zope.exceptions.DuplicationError`` -> ``KeyError`` o ``zope.exceptions.UserError`` -> ``ValueError`` - Moved import of ``IBroken`` interface to use new ``zope.broken`` package, which has no dependencies beyond ``zope.interface``. - Made ``test`` part pull in the extra test requirements of this package. - Split the ``z3c.recipe.compattest`` configuration out into a new file, ``compat.cfg``, to reduce the burden of doing standard unit tests. - Stripped out bogus develop eggs from ``buildout.cfg``. 3.7.0 (2009-01-31) ------------------ - Split this package off ``zope.app.container``. This package is intended to have far less dependencies than ``zope.app.container``. - This package also contains the container implementation that used to be in ``zope.app.folder``. zope2.13-2.13.21/source/zope.container/src/0000755000175000017500000000000012214017546017166 5ustar arnauarnauzope2.13-2.13.21/source/zope.container/src/zope/0000755000175000017500000000000012214017546020143 5ustar arnauarnauzope2.13-2.13.21/source/zope.container/src/zope/container/0000755000175000017500000000000012214017546022125 5ustar arnauarnauzope2.13-2.13.21/source/zope.container/src/zope/container/sample.py0000644000175000017500000000550312214017546023763 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002 Zope Corporation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

"Add an item" ... __setitem__.precondition = preNoZ >>> from zope.container.interfaces import IContainer >>> class C1(object): ... zope.interface.implements(I1, IContainer) ... def __repr__(self): ... return 'C1' Given such a precondition, we can then check whether an object can be added: >>> c1 = C1() >>> checkObject(c1, "bob", None) >>> checkObject(c1, "Zbob", None) Traceback (most recent call last): ... Invalid: Names can not start with Z We can also express constaints on the containers an object can be added to. We do this by setting a field constraint on an object's `__parent__` attribute: >>> import zope.schema A field constraint is a callable object that returns a boolean value: >>> def con1(container): ... "silly container constraint" ... if not hasattr(container, 'x'): ... return False ... return True >>> class I2(zope.interface.Interface): ... __parent__ = zope.schema.Field(constraint = con1) >>> class O(object): ... zope.interface.implements(I2) If the constraint isn't satisfied, we'll get a validation error when we check whether the object can be added: >>> checkObject(c1, "bob", O()) Traceback (most recent call last): ... ConstraintNotSatisfied: C1 Note that the validation error isn't very informative. For that reason, it's better for constraints to raise Invalid errors when they aren't satisfied: >>> def con1(container): ... "silly container constraint" ... if not hasattr(container, 'x'): ... raise zope.interface.Invalid("What, no x?") ... return True >>> class I2(zope.interface.Interface): ... __parent__ = zope.schema.Field(constraint = con1) >>> class O(object): ... zope.interface.implements(I2) >>> checkObject(c1, "bob", O()) Traceback (most recent call last): ... Invalid: What, no x? >>> c1.x = 1 >>> checkObject(c1, "bob", O()) The `checkObject` function is handy when checking whether we can add an existing object to a container, but, sometimes, we want to check whether an object produced by a factory can be added. To do this, we use `checkFactory`: >>> class Factory(object): ... def __call__(self): ... return O() ... def getInterfaces(self): ... return zope.interface.implementedBy(O) >>> factory = Factory() >>> checkFactory(c1, "bob", factory) True >>> del c1.x >>> checkFactory(c1, "bob", factory) False Unlike `checkObject`, `checkFactory`: - Returns a boolean value - Takes a factory (e.g. a class) rather than an argument. The container constraint we defined for C1 isn't actually used to check the factory: >>> c1.x = 1 >>> checkFactory(c1, "Zbob", factory) True To work with `checkFactory`, a container precondition has to implement a factory method. This is because a factory, rather than an object is passed. To illustrate this, we'll make preNoZ its own factory method: >>> preNoZ.factory = preNoZ We can do this (silly thing) because preNoZ doesn't use the object argument. >>> checkFactory(c1, "Zbob", factory) False $Id: constraints.py 107468 2009-12-31 20:12:53Z hannosch $ """ __docformat__ = 'restructuredtext' import sys from zope.dottedname.resolve import resolve import zope.schema from zope.interface import providedBy from zope.container.interfaces import InvalidItemType, InvalidContainerType from zope.container.i18n import ZopeMessageFactory as _ from zope.container.interfaces import IContainer def checkObject(container, name, object): """Check containement constraints for an object and container """ # check __setitem__ precondition containerProvided = providedBy(container) __setitem__ = containerProvided.get('__setitem__') if __setitem__ is not None: precondition = __setitem__.queryTaggedValue('precondition') if precondition is not None: precondition(container, name, object) # check the constraint on __parent__ __parent__ = providedBy(object).get('__parent__') if __parent__ is not None: try: validate = __parent__.validate except AttributeError: pass else: validate(container) if not containerProvided.extends(IContainer): # If it doesn't implement IContainer, it can't contain stuff. raise TypeError( _('Container is not a valid Zope container.') ) def checkFactory(container, name, factory): __setitem__ = providedBy(container).get('__setitem__') if __setitem__ is not None: precondition = __setitem__.queryTaggedValue('precondition') if precondition is not None: try: precondition = precondition.factory except AttributeError: pass else: try: precondition(container, name, factory) except zope.interface.Invalid: return False # check the constraint on __parent__ __parent__ = factory.getInterfaces().get('__parent__') if __parent__ is not None: try: validate = __parent__.validate except AttributeError: pass else: try: validate(container) except zope.interface.Invalid: return False return True class readproperty(object): def __init__(self, func): self.func = func def __get__(self, inst, class_): if inst is None: return self func = self.func return func(inst) class IItemTypePrecondition(zope.interface.Interface): def __call__(container, name, object): """Test whether container setitem arguments are valid.

Once we can rely on the new ZODB3 version exclusively, we can remove the dependency onto the zope.broken distribution. - Never fail if the suggested name is in a wrong type (#227617) - ``checkName`` first checks the parameter type before the emptiness. 3.11.0 (2009-12-31) ------------------- - Copy two trivial classes from zope.cachedescriptors into this package, which allows us to remove that dependency. We didn't actually use any caching properties as the dependency suggested. 3.10.1 (2009-12-29) ------------------- - Moved zope.copypastemove related tests into that package. - Removed no longer used zcml prefix from the configure file. - Stop importing DocTestSuite from zope.testing.doctestunit. Fixes compatibility problems with zope.testing 3.8.4. 3.10.0 (2009-12-15) ------------------- - Break testing dependency on zope.app.testing. - Break testing dependency on zope.app.dependable by moving the code and tests into that package. - Import ISite from zope.component after it was moved there from zope.location. 3.9.1 (2009-10-18) ------------------ - Rerelease 3.9.0 as it had a broken Windows 2.6 egg. - Marked as part of the ZTK. 3.9.0 (2009-08-28) ------------------ - Previous releases should be versioned 3.9.0 as they are not pure bugfix releases and worth a "feature" release, increasing feature version. Packages that depend on any changes introduced in version 3.8.2 or 3.8.3 should depend on version 3.9 or greater. 3.8.3 (2009-08-27) ------------------ - Move IXMLRPCPublisher ZCML registrations for containers from zope.app.publisher.xmlrpc to zope.container for now. 3.8.2 (2009-05-17) ------------------ - Rid ourselves of ``IContained`` interface. This interface was moved to ``zope.location.interfaces``. A b/w compat import still exists to keep old code running. Depend on ``zope.location``>=3.5.4. - Rid ourselves of the implementations of ``IObjectMovedEvent``, ``IObjectAddedEvent``, ``IObjectRemovedEvent`` interfaces and ``ObjectMovedEvent``, ``ObjectAddedEvent`` and ``ObjectRemovedEvent`` classes. B/w compat imports still exist. All of these were moved to ``zope.lifecycleevent``. Depend on ``zope.lifecycleevent``>=3.5.2. - Fix a bug in OrderedContainer where trying to set the value for a key that already exists (duplication error) would actually delete the key from the order, leaving a dangling reference. - Partially break dependency on ``zope.traversing`` by disusing zope.traversing.api.getPath in favor of using ILocationInfo(object).getPath(). The rest of the runtime dependencies on zope.traversing are currently interface dependencies. - Break runtime dependency on ``zope.app.dependable`` by using a zcml condition on the qsubscriber ZCML directive that registers the CheckDependency handler for IObjectRemovedEvent. If ``zope.app.dependable`` is not installed, this subscriber will never be registered. ``zope.app.dependable`` is now a testing dependency only. 3.8.1 (2009-04-03) ------------------ - Fixed misspackaged 3.8.0 3.8.0 (2009-04-03) ------------------ - Change configure.zcml to not depend on zope.app.component. Fixes: https://bugs.launchpad.net/bugs/348329 - Moved the declaration of ``IOrderedContainer.updateOrder`` to a new, basic ``IOrdered`` interface and let ``IOrderedContainer`` inherit it. This allows easier reuse of the declaration. 3.7.2 (2009-03-12) ------------------ - Fix: added missing ComponentLookupError, missing since revision 95429 and missing in last release. - Adapt to the move of IDefaultViewName from zope.component.interfaces to zope.publisher.interfaces. - Add support for reserved names for containers. To specify reserved names for some container, you need to provide an adapter from the container to the ``zope.container.interfaces.IReservedNames`` interface. The default NameChooser is now also aware of reserved names. 3.7.1 (2009-02-05) ------------------ - Raise more "Pythonic" errors from ``__setitem__``, losing the dependency on ``zope.exceptions``: o ``zope.exceptions.DuplicationError`` -> ``KeyError`` o ``zope.exceptions.UserError`` -> ``ValueError`` - Moved import of ``IBroken`` interface to use new ``zope.broken`` package, which has no dependencies beyond ``zope.interface``. - Made ``test`` part pull in the extra test requirements of this package. - Split the ``z3c.recipe.compattest`` configuration out into a new file, ``compat.cfg``, to reduce the burden of doing standard unit tests. - Stripped out bogus develop eggs from ``buildout.cfg``. 3.7.0 (2009-01-31) ------------------ - Split this package off ``zope.app.container``.

Detailed Documentation ---------------------- ===================================== ZPT (Zope Page-Template) Architecture ===================================== There are a number of major components that make up the page-template architecture: - The TAL *compiler* and *interpreter*. This is responsible for compiling source files and for executing compiled templates. See the `zope.tal` package for more information. - An *expression engine* is responsible for compiling expressions and for creating expression execution contexts. It is common for applications to override expression engines to provide custom expression support or to change the way expressions are implemented. The `zope.app.pagetemplate` package uses this to implement trusted and untrusted evaluation; a different engine is used for each, with different implementations of the same type of expressions. Expression contexts support execution of expressions and provide APIs for setting up variable scopes and setting variables. The expression contexts are passed to the TAL interpreter at execution time. The most commonly used expression implementation is that found in `zope.tales`. - Page templates tie everything together. They assemble an expression engine with the TAL interpreter and orchestrate management of source and compiled template data. See `zope.pagetemplate.interfaces`. ============== Page Templates ============== Introduction ------------ Page Templates provide an elegant templating mechanism that achieves a clean separation of presentation and application logic while allowing for designers to work with templates in their visual editing tools (FrontPage, Dreamweaver, GoLive, etc.). This document focuses on usage of Page Templates outside of a Zope context, it does *not* explain how to write page templates as there are several resources on the web which do so. Simple Usage ------------ Using Page Templates outside of Zope3 is very easy and straight forward. A quick example:: >>> from zope.pagetemplate.pagetemplatefile import PageTemplateFile >>> my_pt = PageTemplateFile('hello_world.pt') >>> my_pt() u'Hello World' Subclassing PageTemplates ------------------------- Lets say we want to alter page templates such that keyword arguments appear as top level items in the namespace. We can subclass `PageTemplate` and alter the default behavior of `pt_getContext()` to add them in:: from zope.pagetemplate.pagetemplate import PageTemplate class mypt(PageTemplate): def pt_getContext(self, args=(), options={}, **kw): rval = PageTemplate.pt_getContext(self, args=args) options.update(rval) return options class foo: def getContents(self): return 'hi' So now we can bind objects in a more arbitrary fashion, like the following:: template = """ Good Stuff Here """ pt = mypt() pt.write(template) pt(das_object=foo()) See `interfaces.py`. ======= CHANGES ======= 3.5.2 (2010-07-08) ------------------ - Fixed PTRuntimeError exception messages to be consistent across Python versions, and compatibile with the output under Python 2.4. (More readable than the previous output under Python 2.6 as well.) 3.5.1 (2010-04-30) ------------------ - Removed use of 'zope.testing.doctestunit' in favor of stdlib's doctest. - Added dependency on "zope.security [untrustedpython]" because the 'engine' module uses it. 3.5.0 (2009-05-25) ------------------ - Added test coverage reporting support. - Moved 'engine' module and related test scaffolding here from ``zope.app.pagetemplate`` package. 3.4.2 (2009-03-17) ------------------ - Remove old zpkg-related DEPENDENCIES.cfg file. - Change package's mailing list address to zope-dev at zope.org, as zope3-dev at zope.org is now retired. - Change `cheeseshop` to `pypi` in the packages' homepage url. 3.4.1 (2009-01-27) ------------------ - Fix test due to recent changes in zope.tal. 3.4.0 (2007-10-02) ------------------ - Initial release independent of the Zope 3 tree. 3.2.0 (2006-01-05) ------------------ - Corresponds to the verison of the zope.pagetemplate package shipped as part of the Zope 3.2.0 release. - ZPTPage macro expansion: changed label text to match the corresponding label in Zope 2 and activated the name spaces for macro expansion in 'read'. See http://www.zope.org/Collectors/Zope3-dev/199 - Coding style cleanups. 3.1.0 (2005-10-03) ------------------ - Corresponds to the verison of the zope.pagetemplate package shipped as part of the Zope 3.1.0 release. - Fixed apidoc and Cookie, which were using wrong descriptor class (changed to 'property'). See http://www.zope.org/Collectors/Zope3-dev/387 - Documentation / style / testing cleanups. 3.0.0 (2004-11-07) ------------------ - Corresponds to the verison of the zope.pagetemplate package shipped as part of the Zope X3.0.0 release.

Detailed Documentation ---------------------- ===================================== ZPT (Zope Page-Template) Architecture ===================================== There are a number of major components that make up the page-template architecture: - The TAL *compiler* and *interpreter*. This is responsible for compiling source files and for executing compiled templates. See the `zope.tal` package for more information. - An *expression engine* is responsible for compiling expressions and for creating expression execution contexts. It is common for applications to override expression engines to provide custom expression support or to change the way expressions are implemented. The `zope.app.pagetemplate` package uses this to implement trusted and untrusted evaluation; a different engine is used for each, with different implementations of the same type of expressions. Expression contexts support execution of expressions and provide APIs for setting up variable scopes and setting variables. The expression contexts are passed to the TAL interpreter at execution time. The most commonly used expression implementation is that found in `zope.tales`. - Page templates tie everything together. They assemble an expression engine with the TAL interpreter and orchestrate management of source and compiled template data. See `zope.pagetemplate.interfaces`. ============== Page Templates ============== Introduction ------------ Page Templates provide an elegant templating mechanism that achieves a clean separation of presentation and application logic while allowing for designers to work with templates in their visual editing tools (FrontPage, Dreamweaver, GoLive, etc.). This document focuses on usage of Page Templates outside of a Zope context, it does *not* explain how to write page templates as there are several resources on the web which do so. Simple Usage ------------ Using Page Templates outside of Zope3 is very easy and straight forward. A quick example:: >>> from zope.pagetemplate.pagetemplatefile import PageTemplateFile >>> my_pt = PageTemplateFile('hello_world.pt') >>> my_pt() u'Hello World' Subclassing PageTemplates ------------------------- Lets say we want to alter page templates such that keyword arguments appear as top level items in the namespace. We can subclass `PageTemplate` and alter the default behavior of `pt_getContext()` to add them in:: from zope.pagetemplate.pagetemplate import PageTemplate class mypt(PageTemplate): def pt_getContext(self, args=(), options={}, **kw): rval = PageTemplate.pt_getContext(self, args=args) options.update(rval) return options class foo: def getContents(self): return 'hi' So now we can bind objects in a more arbitrary fashion, like the following:: template = """ Good Stuff Here """ pt = mypt() pt.write(template) pt(das_object=foo()) See `interfaces.py`. ======= CHANGES ======= 3.5.2 (2010-07-08) ------------------ - Fixed PTRuntimeError exception messages to be consistent across Python versions, and compatibile with the output under Python 2.4.

Home-page: http://pypi.python.org/pypi/Products.ZCatalog Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: Overview ======== The ZCatalog is Zope 2’s built in search engine. It allows you to categorize and search all kinds of Zope objects. It comes with a variety of indexes for different types of data. Changelog ========= 2.13.23 (2012-04-26) -------------------- - Fixed another issue with preserving score values, when a custom index was queried first which was neither ILimitedResultIndex aware nor return scores, and a later index was of the default ZCTextIndex type. 2.13.22 (2011-11-17) -------------------- - Added a new `load_from_path` class method to the `PriorityMap`, which allows one to load a plan from a file, instead of a module via an environment var. 2.13.21 (2011-10-20) -------------------- - Refactored value index logic. Determine value indexes per catalog instead of globally. Store value index set in the priority map, so it can be seen in the ZMI and stored in the module level storage. - Added support for using ZCatalog as local utility. This feature requires the optional `five.globalrequest` dependency. 2.13.20 (2011-08-23) -------------------- - Fixed incorrect calculation of batches in the second half of the result set in sortResults. 2.13.19 (2011-08-20) -------------------- - Increase plan precision to 4 digits in its string representation. 2.13.18 (2011-07-29) -------------------- - In the string representation of a catalog plan, round the times to at most two digits after the comma. 2.13.17 (2011-07-29) -------------------- - Put back the `weightedIntersection` optimization but guard against results with values and do the appropriate fallback to the weighted version. 2.13.16 (2011-07-24) -------------------- - Restored preserving score values from ZCTextIndex indices. https://bugs.launchpad.net/zope2/+bug/815469 2.13.15 (2011-06-30) -------------------- - Fixed undefined variables in BooleanIndex inline migration code. - Fixed BooleanIndex' items method so the ZMI browse view works. 2.13.14 (2011-05-19) -------------------- - Fixed addition of two LazyCat's if any of them was already flattened. - Extend BooleanIndex by making the indexed value variable instead of hardcoding it to `True`. The indexed value will determine the smaller set automatically and choose its best value. An inline switch is done once the indexed value set grows larger than 60% of the total length. 60% was chosen to avoid constant switching for indexes that have an almost equal distribution of `True/False`. - Substitute catalog entry in UUIDIndex error message. 2.13.13 (2011-05-04) -------------------- - Optimize `Catalog.updateMetadata` avoiding a `self.uids` lookup and removing inline migration code for converting `self.data` from non-IOBTree types. - In the path index, don't update data if the value hasn't changed. 2.13.12 (2011-05-02) -------------------- - Optimize DateRangeIndex for better conflict resolution handling. It always starts out with storing an IITreeSet of the value instead of special casing storing an int for a single value. The `single value as int` optimization should be provided via a separate API to be called periodically outside the context of a normal request. - Replaced `weightedIntersection` and `weightedUnion` calls with their non-weighted version, as we didn't pass in weights. 2.13.11 (2011-05-02) -------------------- - Fix possible TypeError in `sortResults` method if only b_start but not b_size has been provided. - Prevent the new UUIDIndex from acquiring attributes via Acquisition. 2.13.10 (2011-04-21) -------------------- - Handle `TypeErrors` in the KeywordIndex if an indexed attribute is a method with required arguments. - Added reporting of the intersection time of each index' result with the result set of the other indexes and consider this time to be part of each index time for prioritizing the index. - Removed tracking of result length from the query plan. The calculation of the length of an intermediate index result can itself be expensive. 2.13.9 (2011-04-10) ------------------- - Added a floor and ceiling value to the date range index. Values outside the specified range will be interpreted the same way as passing `None`, i.e. `since the beginning of time` and `until the end of it`. This allows the index to apply its optimizations, while objects with values outside this range can still be stored in a normal date index, which omits explicitly passed in `None` values. 2.13.8 (2011-04-01) ------------------- - Fixed bug in date range index, which would omit objects exactly matching the query term if a resultset was provided. - Fixed the BooleanIndex to not index objects without the cataloged attribute. 2.13.7 (2011-02-15) ------------------- - Fixed the `DateIndex._unindex` to be of type `IIBTree` instead of `OIBTree`. It stores document ids as keys, which can only be ints. 2.13.6 (2011-02-10) ------------------- - Remove docstrings from various methods, as they shouldn't be web-publishable. 2.13.5 (2011-02-05) ------------------- - Fixed test failures introduced in 2.13.4. 2.13.4 (2011-02-05) ------------------- - Added a new UUIDIndex, based on the common UnIndex. It behaves like a FieldIndex, but can only store one document id per value, so there's a 1:1 mapping from value to document id. An error is logged if a different document id is indexed for an already taken value. The internal data structures are optimized for this and avoid storing one IITreeSet per value. - Optimize sorting in presence of batching arguments. If a batch from the end of the result set is requested, we internally reverse the sorting order and at the end reverse the lazy sequence again. In a sequence with 100 entries, if we request the batch with items 80 to 90, we now reverse sort 20 items (100 to 80), slice of the first ten items and then reverse them. Before we would had to sort the first 90 items and then slice of the last 10. - If batching arguments are provided, limit the returned lazy sequence to the items in the required batch instead of returning leading items falling outside of the requested batch. - Fixed inline `IISet` to `IITreeSet` conversion code inside DateRangeIndex' `_insertForwardIndexEntry` method. 2.13.3 (2011-01-01) ------------------- - Avoid locale-dependent test condition in `test_length_with_filter`. 2.13.2 (2010-12-31) ------------------- - Preserve `actual_result_count` on flattening nested LazyCat's. - Preserve the `actual_result_count` on all lazy return values. This allows to get proper batching information from catalog results which have been restricted by `sort_limit`. - Made sure `actual_result_count` is available on all lazy classes and falls back to `__len__` if not explicitly provided. - Optimized length calculation of Lazy classes. 2.13.1 (2010-12-25) ------------------- - Added automatic sorting limit calculation based on batch arguments. If the query contains a `b_start` and `b_size` argument and no explicit `sort_limit` is provided, the sort limit will be calculated as `b_start + b_size`. - Avoid pre-allocation of marker items in `LazyMap`. 2.13.0 (2010-12-25) ------------------- - Fix `LazyMap` to avoid unnecessary function calls. - Released as separate distribution.

Determine value indexes per catalog instead of globally. Store value index set in the priority map, so it can be seen in the ZMI and stored in the module level storage. - Added support for using ZCatalog as local utility. This feature requires the optional `five.globalrequest` dependency. 2.13.20 (2011-08-23) -------------------- - Fixed incorrect calculation of batches in the second half of the result set in sortResults. 2.13.19 (2011-08-20) -------------------- - Increase plan precision to 4 digits in its string representation. 2.13.18 (2011-07-29) -------------------- - In the string representation of a catalog plan, round the times to at most two digits after the comma. 2.13.17 (2011-07-29) -------------------- - Put back the `weightedIntersection` optimization but guard against results with values and do the appropriate fallback to the weighted version. 2.13.16 (2011-07-24) -------------------- - Restored preserving score values from ZCTextIndex indices. https://bugs.launchpad.net/zope2/+bug/815469 2.13.15 (2011-06-30) -------------------- - Fixed undefined variables in BooleanIndex inline migration code. - Fixed BooleanIndex' items method so the ZMI browse view works. 2.13.14 (2011-05-19) -------------------- - Fixed addition of two LazyCat's if any of them was already flattened. - Extend BooleanIndex by making the indexed value variable instead of hardcoding it to `True`. The indexed value will determine the smaller set automatically and choose its best value. An inline switch is done once the indexed value set grows larger than 60% of the total length. 60% was chosen to avoid constant switching for indexes that have an almost equal distribution of `True/False`. - Substitute catalog entry in UUIDIndex error message. 2.13.13 (2011-05-04) -------------------- - Optimize `Catalog.updateMetadata` avoiding a `self.uids` lookup and removing inline migration code for converting `self.data` from non-IOBTree types. - In the path index, don't update data if the value hasn't changed. 2.13.12 (2011-05-02) -------------------- - Optimize DateRangeIndex for better conflict resolution handling. It always starts out with storing an IITreeSet of the value instead of special casing storing an int for a single value. The `single value as int` optimization should be provided via a separate API to be called periodically outside the context of a normal request. - Replaced `weightedIntersection` and `weightedUnion` calls with their non-weighted version, as we didn't pass in weights. 2.13.11 (2011-05-02) -------------------- - Fix possible TypeError in `sortResults` method if only b_start but not b_size has been provided. - Prevent the new UUIDIndex from acquiring attributes via Acquisition. 2.13.10 (2011-04-21) -------------------- - Handle `TypeErrors` in the KeywordIndex if an indexed attribute is a method with required arguments. - Added reporting of the intersection time of each index' result with the result set of the other indexes and consider this time to be part of each index time for prioritizing the index. - Removed tracking of result length from the query plan. The calculation of the length of an intermediate index result can itself be expensive. 2.13.9 (2011-04-10) ------------------- - Added a floor and ceiling value to the date range index. Values outside the specified range will be interpreted the same way as passing `None`, i.e. `since the beginning of time` and `until the end of it`. This allows the index to apply its optimizations, while objects with values outside this range can still be stored in a normal date index, which omits explicitly passed in `None` values. 2.13.8 (2011-04-01) ------------------- - Fixed bug in date range index, which would omit objects exactly matching the query term if a resultset was provided. - Fixed the BooleanIndex to not index objects without the cataloged attribute. 2.13.7 (2011-02-15) ------------------- - Fixed the `DateIndex._unindex` to be of type `IIBTree` instead of `OIBTree`. It stores document ids as keys, which can only be ints. 2.13.6 (2011-02-10) ------------------- - Remove docstrings from various methods, as they shouldn't be web-publishable. 2.13.5 (2011-02-05) ------------------- - Fixed test failures introduced in 2.13.4. 2.13.4 (2011-02-05) ------------------- - Added a new UUIDIndex, based on the common UnIndex. It behaves like a FieldIndex, but can only store one document id per value, so there's a 1:1 mapping from value to document id. An error is logged if a different document id is indexed for an already taken value. The internal data structures are optimized for this and avoid storing one IITreeSet per value. - Optimize sorting in presence of batching arguments. If a batch from the end of the result set is requested, we internally reverse the sorting order and at the end reverse the lazy sequence again. In a sequence with 100 entries, if we request the batch with items 80 to 90, we now reverse sort 20 items (100 to 80), slice of the first ten items and then reverse them. Before we would had to sort the first 90 items and then slice of the last 10. - If batching arguments are provided, limit the returned lazy sequence to the items in the required batch instead of returning leading items falling outside of the requested batch. - Fixed inline `IISet` to `IITreeSet` conversion code inside DateRangeIndex' `_insertForwardIndexEntry` method. 2.13.3 (2011-01-01) ------------------- - Avoid locale-dependent test condition in `test_length_with_filter`. 2.13.2 (2010-12-31) ------------------- - Preserve `actual_result_count` on flattening nested LazyCat's. - Preserve the `actual_result_count` on all lazy return values. This allows to get proper batching information from catalog results which have been restricted by `sort_limit`. - Made sure `actual_result_count` is available on all lazy classes and falls back to `__len__` if not explicitly provided. - Optimized length calculation of Lazy classes. 2.13.1 (2010-12-25) ------------------- - Added automatic sorting limit calculation based on batch arguments. If the query contains a `b_start` and `b_size` argument and no explicit `sort_limit` is provided, the sort limit will be calculated as `b_start + b_size`. - Avoid pre-allocation of marker items in `LazyMap`. 2.13.0 (2010-12-25) ------------------- - Fix `LazyMap` to avoid unnecessary function calls. - Released as separate distribution. zope2.13-2.13.21/source/Products.ZCatalog/src/0000755000175000017500000000000012214017452017532 5ustar arnauarnauzope2.13-2.13.21/source/Products.ZCatalog/src/Products/0000755000175000017500000000000012214017452021335 5ustar arnauarnauzope2.13-2.13.21/source/Products.ZCatalog/src/Products/ZCatalog/0000755000175000017500000000000012214017452023041 5ustar arnauarnauzope2.13-2.13.21/source/Products.ZCatalog/src/Products/ZCatalog/ZCatalog.py0000644000175000017500000011036312214017452025123 0ustar arnauarnau############################################################################## # # Copyright (c) 2002 Zope Foundation and Contributors. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

""" from zope.interface import Interface class IZCatalog(Interface): """ZCatalog object A ZCatalog contains arbitrary index like references to Zope objects. ZCatalog's can index object attribute using a variety of "plug-in" index types. Several index types are included, and others may be added. Text -- Text indexes index textual content. The index can be used to search for objects containing certain words. Field -- Field indexes index atomic values. The index can be used to search for objects that have certain properties. Keyword -- Keyword indexes index sequences of values. The index can be used to search for objects that match one or more of the search terms. Path -- Path indexes index URI paths. They allow you to find objects based on their placement in a hierarchy. Date -- Date indexes index date and type data. They are a type of field index specifically optimized for indexing dates. Date Range -- Date range indexes index time intervals. They are designed for efficient searching of dates falling between two boundaries (such as effective / expiration dates). Topic -- Topic indexes store prefiltered sets of documents. They are used to optimize complex queries into a single fast query by prefiltering documents by an expression The ZCatalog can maintain a table of extra data about cataloged objects. This information can be used on search result pages to show information about a search result. The meta-data table schema is used to build the schema for ZCatalog Result objects. The objects have the same attributes as the column of the meta-data table. ZCatalog does not store references to the objects themselves, but rather to a unique identifier that defines how to get to the object. In Zope, this unique identifier is the object's relative path to the ZCatalog (since two Zope objects cannot have the same URL, this is an excellent unique qualifier in Zope). """ def catalog_object(obj, uid, idxs=None, update_metadata=1): """Catalogs the object 'obj' with the unique identifier 'uid'. The uid must be a physical path, either absolute or relative to the catalog. If provided, idxs specifies the names of indexes to update.

""" def getIndexObjects(): """Returns a list of acquisition wrapped index objects """ def searchResults(REQUEST=None, **kw): """Search the catalog. Search terms can be passed in the REQUEST or as keyword arguments. Search queries consist of a mapping of index names to search parameters. You can either pass a mapping to searchResults as the variable 'REQUEST' or you can use index names and search parameters as keyword arguments to the method, in other words:: searchResults(title='Elvis Exposed', author='The Great Elvonso') is the same as:: searchResults({'title' : 'Elvis Exposed', 'author : 'The Great Elvonso'}) In these examples, 'title' and 'author' are indexes. This query will return any objects that have the title *Elvis Exposed* AND also are authored by *The Great Elvonso*. Terms that are passed as keys and values in a searchResults() call are implicitly ANDed together. To OR two search results, call searchResults() twice and add concatenate the results like this:: results = ( searchResults(title='Elvis Exposed') + searchResults(author='The Great Elvonso') ) This will return all objects that have the specified title OR the specified author. There are some special index names you can pass to change the behavior of the search query: sort_on -- This parameters specifies which index to sort the results on. sort_order -- You can specify 'reverse' or 'descending'. Default behavior is to sort ascending. sort_limit -- An optimization hint to tell the catalog how many results you are really interested in. See the limit argument to the search method for more details. There are some rules to consider when querying this method: - an empty query mapping (or a bogus REQUEST) returns all items in the catalog. - results from a query involving only field/keyword indexes, e.g. {'id':'foo'} and no 'sort_on' will be returned unsorted. - results from a complex query involving a field/keyword index *and* a text index, e.g. {'id':'foo','PrincipiaSearchSource':'bar'} and no 'sort_on' will be returned unsorted. - results from a simple text index query e.g.{'PrincipiaSearchSource':'foo'} will be returned sorted in descending order by 'score'. A text index cannot beused as a 'sort_on' parameter, and attempting to do so will raise an error. Depending on the type of index you are querying, you may be able to provide more advanced search parameters that can specify range searches or wildcards.

This is an optimization hint used in conjunction with a sort_index. If possible ZCatalog will use a different sort algorithm that uses much less memory and scales better then a full sort. The actual number of records returned is not guaranteed to be <= limit. You still need to apply the same batching to the results. Since the len() of the results will no longer be the actual result count, you can use the "actual_result_count" attribute of the lazy result object instead to determine the size of the full result set. merge -- Return merged, lazy results (like searchResults) or raw results for later merging.

Catalog record at

The goal of this page is to provide basic debugging information about what is in the Catalog on a specific object. Listed below is all the information that the Catalog currently contains for the above specified object. This information should match what is currently in the instance of that object.


Metadata Contents

Metadata is the information that the Catalog keeps inside of its internal structure so that it can answer questions quickly. This is then returned in the "brain" that the Catalog gives back during searches.
  Key Value
  &dtml-sequence-key; &dtml-sequence-item;

Index Contents

The following table gives information that is contained in the various indexes of the Catalog. In the case of Keyword or Text indexes, the results are returned as a tuple, and will show as '(one, two, three)', rather than in a more normal way.

Catalog Maintenance

Updating the catalog will update all catalog records and remove invalid records. It does this by clearing all indexes and re-cataloging all currently indexed objects.

Clearing the catalog will remove all entries.

Log progress of reindexing every N objects to the Zope logger (set to 0 to disable logging)

Subtransactions

Subtransactions allow Zope to commit small parts of a transaction over a period of time instead of all at once. For ZCatalog, this means using subtransactions can signficantly reduce the memory requirements needed to index huge amounts of text all at once. Currently, subtransactions are only applied to text indexes.

If enabled, subtransactions will reduce the memory requirements of ZCatalog, but at the expense of speed. If you choose to enable subtransactions, you can adjust how often ZCatalog commits a subtransactions by adjusting the threshold below.

Subtransactions are Enabled Disabled

The Subtransaction threshold is the number of objects cataloged in the context of a single transaction that the catalog will index before it commits a subtransaction. If this number is low, the Catalog will take longer to index but consume less memory. If this number is higher, the Catalog will index quickly but consume much more memory.
zope2.13-2.13.21/source/Products.ZCatalog/src/Products/ZCatalog/dtml/catalogSchema.dtml0000644000175000017500000000470512214017452027424 0ustar arnauarnau

This list defines what per object meta data the Catalog will store. When objects get cataloged, the values of any attributes they may have which match a name in this list will get stored in a table in the Catalog. The Catalog then uses this information to create result objects that are returned whenever the catalog is searched. It is important to understand that when the Catalog is searched, it returns a list of result objects, not the cataloged objects themselves, so if you want to use the value of an object's attribute in the result of a search, that attribute must be in this list

It is generally a good idea to keep this list lightweight. It is useful, for example, to keep the 'summary' meta data of a text document (like the first 200 characters) but not the text content in it's entirety (it is useful in this example to index the text contents, which is configured in the Indexes View tab). This way, the summary data may be shown in the search results.

The query report shows catalog queries that perform slowly. For each index there's an additional entry for the time the intersection of the index result with the result by the other indexes took. These are marked with a #intersection postfix. The time reported for the index is the sum of the intersection time and the time the index itself took. Subtract the intersection time, if you want to know the pure index time.

This list defines what indexes the Catalog will contain. When objects get cataloged, the values of any attributes which match an index in this list will get indexed.

If you add indexes to a Catalog which contains indexed objects, you MUST at the least re-index your newly added index. You may want to update the whole Catalog.

DateIndex is a pluggable index which addresses these two issues as follows: o It normalizes the indexed value to an integer representation with a granularity of one minute. o It normalizes the 'query' value into the same form. o Objects which return 'None' for the index query are omitted from the index. zope2.13-2.13.21/source/Products.ZCatalog/src/Products/PluginIndexes/DateIndex/DateIndex.py0000644000175000017500000002172712214017452030210 0ustar arnauarnau############################################################################## # # Copyright (c) 2002 Zope Foundation and Contributors. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

This is very similiar to a substring search on strings. How it works Assume we have to index an object with id=xxx and the physical path '/zoo/animals/africa/tiger.doc'. We split the path into its components and keep track of the level of every component. Inside the index we store pairs(component,level) and the ids of the documents:: (component,level) id of document ----------------------------------------- ('zoo',0) xxx ('animals',1) xxx ('africa',2) xxx Note that we do not store the id of the objects itself inside the path index. Searching with the PathIndex The PathIndex allows you to search for all object ids whose objects match a physical path query. The query is split into components and matched against the index. E.g. '/zoo/animals' will match in the example above but not '/zoo1/animals'. The default behaviour is to start matching at level 0. To start matching on another level on can specify an additional level parameter (see API) API 'query' -- A single or list of Path component(s) to be searched. 'level' -- level to start searching (optional,default: 0). If level=-1 we search through all levels. 'operator' -- either 'or' or 'and' (optional, default: 'or') Example Objects with the following ids and physical path should be stored in the ZCatalog 'MyCAT':: id physical path ---------------------------- 1 /aa/bb/aa/1.txt 2 /aa/bb/bb/2.txt 3 /aa/bb/cc/3.txt 4 /bb/bb/aa/4.txt 5 /bb/bb/bb/5.txt 6 /bb/bb/cc/6.txt 7 /cc/bb/aa/7.txt 8 /cc/bb/bb/8.txt 9 /cc/bb/cc/9.txt Query found ids ------------------------------------------- query='/aa/bb',level=0 [1,2,3] query='/bb/bb',level=0 [4,5,6] query='/bb/bb',level=1 [2,5,8] query='/bb/bb',level=-1 [2,4,5,6,8] query='/xx' ,level=-1 [] zope2.13-2.13.21/source/Products.ZCatalog/src/Products/PluginIndexes/PathIndex/__init__.py0000644000175000017500000000004712214017452030111 0ustar arnauarnau# empty comment for winzip and friends zope2.13-2.13.21/source/Products.ZCatalog/src/Products/PluginIndexes/PathIndex/tests/0000755000175000017500000000000012214017452027141 5ustar arnauarnauzope2.13-2.13.21/source/Products.ZCatalog/src/Products/PluginIndexes/PathIndex/tests/__init__.py0000644000175000017500000000007012214017452031247 0ustar arnauarnau# This file is needed to make this directory a package. ././@LongLink0000000000000000000000000000014600000000000011566 Lustar rootrootzope2.13-2.13.21/source/Products.ZCatalog/src/Products/PluginIndexes/PathIndex/tests/testPathIndex.pyzope2.13-2.13.21/source/Products.ZCatalog/src/Products/PluginIndexes/PathIndex/tests/testPathIndex.p0000644000175000017500000004722612214017452032121 0ustar arnauarnau############################################################################## # # Copyright (c) 2002 Zope Foundation and Contributors. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

A FilteredSet consists of an expression and a set of internal ZCatalog document identifiers that represent a pre-calculated result list for performance reasons. Instead of executing the same query on a ZCatalog multiple times it is much faster to use a TopicIndex instead. Building up FilteredSets happens on the fly when objects are cataloged and uncatalogued. Every indexed object is evaluated against the expressions of every FilteredSet. An object is added to a FilteredSet if the expression with the object evaluates to 1. Uncatalogued objects are removed from the FilteredSet. Types of FilteredSet PythonFilteredSet A PythonFilteredSet evaluates using the eval() function inside the context of the FilteredSet class. The object to be indexes must be referenced inside the expression using "o.". Examples:: "o.meta_type=='DTML Method'" Queries on TopicIndexes A TopicIndex is queried in the same way as other ZCatalog Indexes and supports usage of the 'operator' parameter to specify how to combine search results. API The TopicIndex implements the API for pluggable Indexes.

A TopicIndex is a container for so-called FilteredSets that consist of an expression and a set of internal ZCatalog document identifiers that fulfill this expression. TopicIndexes are useful for performance reasons when search queries take too long and pre-calculated result sets offer a better performance.

This query *can* be done using a pair of indexes, but this implementation is hideously expensive: o DateTime instances are *huge*, both in RAM and on disk. o DateTime instances maintain an absurd amount of precision, far beyond any reasonable search criteria for "normal" cases. o Results must be fetched and intersected between two indexes. o Handling objects which do not specify both endpoints (i.e., where the interval is open or half-open) is iffy, as the default value needs to be coerced into a different abnormal value for each end to permit ordered comparison. o The *very* common case of the open interval (neither endpoint specified) should be optimized. DateRangeIndex is a pluggable index which addresses these issues as follows: o It groups the "open" case into a special set, '_always'. o It maintains separate ordered sets for each of the "half-open" cases. o It performs the expensive "intersect two range search" operation only on the (usually small) set of objects which provide a closed interval. o It flattens the key values into integers with granularity of one minute. o It normalizes the 'query' value into the same form. zope2.13-2.13.21/source/Products.ZCatalog/src/Products/PluginIndexes/DateRangeIndex/tests/0000755000175000017500000000000012214017452030077 5ustar arnauarnau././@LongLink0000000000000000000000000000014600000000000011566 Lustar rootrootzope2.13-2.13.21/source/Products.ZCatalog/src/Products/PluginIndexes/DateRangeIndex/tests/__init__.pyzope2.13-2.13.21/source/Products.ZCatalog/src/Products/PluginIndexes/DateRangeIndex/tests/__init__.p0000644000175000017500000000125312214017452032020 0ustar arnauarnau############################################################################## # # Copyright (c) 2003 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

A DateRangeIndex takes the name of two input attributes; one containing the start date of the range, the second the end of the range. This index is filled with range information based on those two markers. You can then search for objects for those where a given date falls within the range.

Home-page: http://pypi.python.org/pypi/Products.ZCatalog Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: Overview ======== The ZCatalog is Zope 2’s built in search engine. It allows you to categorize and search all kinds of Zope objects. It comes with a variety of indexes for different types of data. Changelog ========= 2.13.23 (2012-04-26) -------------------- - Fixed another issue with preserving score values, when a custom index was queried first which was neither ILimitedResultIndex aware nor return scores, and a later index was of the default ZCTextIndex type. 2.13.22 (2011-11-17) -------------------- - Added a new `load_from_path` class method to the `PriorityMap`, which allows one to load a plan from a file, instead of a module via an environment var. 2.13.21 (2011-10-20) -------------------- - Refactored value index logic. Determine value indexes per catalog instead of globally. Store value index set in the priority map, so it can be seen in the ZMI and stored in the module level storage. - Added support for using ZCatalog as local utility. This feature requires the optional `five.globalrequest` dependency. 2.13.20 (2011-08-23) -------------------- - Fixed incorrect calculation of batches in the second half of the result set in sortResults. 2.13.19 (2011-08-20) -------------------- - Increase plan precision to 4 digits in its string representation. 2.13.18 (2011-07-29) -------------------- - In the string representation of a catalog plan, round the times to at most two digits after the comma. 2.13.17 (2011-07-29) -------------------- - Put back the `weightedIntersection` optimization but guard against results with values and do the appropriate fallback to the weighted version. 2.13.16 (2011-07-24) -------------------- - Restored preserving score values from ZCTextIndex indices. https://bugs.launchpad.net/zope2/+bug/815469 2.13.15 (2011-06-30) -------------------- - Fixed undefined variables in BooleanIndex inline migration code. - Fixed BooleanIndex' items method so the ZMI browse view works. 2.13.14 (2011-05-19) -------------------- - Fixed addition of two LazyCat's if any of them was already flattened. - Extend BooleanIndex by making the indexed value variable instead of hardcoding it to `True`. The indexed value will determine the smaller set automatically and choose its best value. An inline switch is done once the indexed value set grows larger than 60% of the total length. 60% was chosen to avoid constant switching for indexes that have an almost equal distribution of `True/False`. - Substitute catalog entry in UUIDIndex error message. 2.13.13 (2011-05-04) -------------------- - Optimize `Catalog.updateMetadata` avoiding a `self.uids` lookup and removing inline migration code for converting `self.data` from non-IOBTree types. - In the path index, don't update data if the value hasn't changed. 2.13.12 (2011-05-02) -------------------- - Optimize DateRangeIndex for better conflict resolution handling. It always starts out with storing an IITreeSet of the value instead of special casing storing an int for a single value. The `single value as int` optimization should be provided via a separate API to be called periodically outside the context of a normal request. - Replaced `weightedIntersection` and `weightedUnion` calls with their non-weighted version, as we didn't pass in weights. 2.13.11 (2011-05-02) -------------------- - Fix possible TypeError in `sortResults` method if only b_start but not b_size has been provided. - Prevent the new UUIDIndex from acquiring attributes via Acquisition. 2.13.10 (2011-04-21) -------------------- - Handle `TypeErrors` in the KeywordIndex if an indexed attribute is a method with required arguments. - Added reporting of the intersection time of each index' result with the result set of the other indexes and consider this time to be part of each index time for prioritizing the index. - Removed tracking of result length from the query plan. The calculation of the length of an intermediate index result can itself be expensive. 2.13.9 (2011-04-10) ------------------- - Added a floor and ceiling value to the date range index. Values outside the specified range will be interpreted the same way as passing `None`, i.e. `since the beginning of time` and `until the end of it`. This allows the index to apply its optimizations, while objects with values outside this range can still be stored in a normal date index, which omits explicitly passed in `None` values. 2.13.8 (2011-04-01) ------------------- - Fixed bug in date range index, which would omit objects exactly matching the query term if a resultset was provided. - Fixed the BooleanIndex to not index objects without the cataloged attribute. 2.13.7 (2011-02-15) ------------------- - Fixed the `DateIndex._unindex` to be of type `IIBTree` instead of `OIBTree`. It stores document ids as keys, which can only be ints. 2.13.6 (2011-02-10) ------------------- - Remove docstrings from various methods, as they shouldn't be web-publishable. 2.13.5 (2011-02-05) ------------------- - Fixed test failures introduced in 2.13.4. 2.13.4 (2011-02-05) ------------------- - Added a new UUIDIndex, based on the common UnIndex. It behaves like a FieldIndex, but can only store one document id per value, so there's a 1:1 mapping from value to document id. An error is logged if a different document id is indexed for an already taken value. The internal data structures are optimized for this and avoid storing one IITreeSet per value. - Optimize sorting in presence of batching arguments. If a batch from the end of the result set is requested, we internally reverse the sorting order and at the end reverse the lazy sequence again. In a sequence with 100 entries, if we request the batch with items 80 to 90, we now reverse sort 20 items (100 to 80), slice of the first ten items and then reverse them. Before we would had to sort the first 90 items and then slice of the last 10. - If batching arguments are provided, limit the returned lazy sequence to the items in the required batch instead of returning leading items falling outside of the requested batch. - Fixed inline `IISet` to `IITreeSet` conversion code inside DateRangeIndex' `_insertForwardIndexEntry` method. 2.13.3 (2011-01-01) ------------------- - Avoid locale-dependent test condition in `test_length_with_filter`. 2.13.2 (2010-12-31) ------------------- - Preserve `actual_result_count` on flattening nested LazyCat's. - Preserve the `actual_result_count` on all lazy return values. This allows to get proper batching information from catalog results which have been restricted by `sort_limit`. - Made sure `actual_result_count` is available on all lazy classes and falls back to `__len__` if not explicitly provided. - Optimized length calculation of Lazy classes. 2.13.1 (2010-12-25) ------------------- - Added automatic sorting limit calculation based on batch arguments. If the query contains a `b_start` and `b_size` argument and no explicit `sort_limit` is provided, the sort limit will be calculated as `b_start + b_size`. - Avoid pre-allocation of marker items in `LazyMap`. 2.13.0 (2010-12-25) ------------------- - Fix `LazyMap` to avoid unnecessary function calls. - Released as separate distribution.

As a meta-class, ExtensionClass provides the following features: - Support for a class initialiser: >>> from ExtensionClass import ExtensionClass, Base >>> class C(Base): ... def __class_init__(self): ... print 'class init called' ... print self.__name__ ... def bar(self): ... return 'bar called' class init called C >>> c = C() >>> int(c.__class__ is C) 1 >>> int(c.__class__ is type(c)) 1 - Making sure that every instance of the meta-class has Base as a base class: >>> class X: ... __metaclass__ = ExtensionClass >>> Base in X.__mro__ 1 - Provide an inheritedAttribute method for looking up attributes in base classes: >>> class C2(C): ... def bar(*a): ... return C2.inheritedAttribute('bar')(*a), 42 class init called C2 >>> o = C2() >>> o.bar() ('bar called', 42) This is for compatability with old code. New code should use super instead. The base class, Base, exists mainly to support the __of__ protocol. The __of__ protocol is similar to __get__ except that __of__ is called when an implementor is retrieved from an instance as well as from a class: >>> class O(Base): ... def __of__(*a): ... return a >>> o1 = O() >>> o2 = O() >>> C.o1 = o1 >>> c.o2 = o2 >>> c.o1 == (o1, c) 1 >>> C.o1 == o1 1 >>> int(c.o2 == (o2, c)) 1 We accomplish this by making a class that implements __of__ a descriptor and treating all descriptor ExtensionClasses this way. That is, if an extension class is a descriptor, it's __get__ method will be called even when it is retrieved from an instance. >>> class O(Base): ... def __get__(*a): ... return a ... >>> o1 = O() >>> o2 = O() >>> C.o1 = o1 >>> c.o2 = o2 >>> int(c.o1 == (o1, c, type(c))) 1 >>> int(C.o1 == (o1, None, type(c))) 1 >>> int(c.o2 == (o2, c, type(c))) 1 $Id: __init__.py 40218 2005-11-18 14:39:19Z andreasjung $ """ from _ExtensionClass import * zope2.13-2.13.21/source/Missing/include/ExtensionClass/tests.py0000644000175000017500000004744512214017442023164 0ustar arnauarnau############################################################################## # # Copyright (c) 2003 Zope Corporation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

The basic idea is: I'll call this the "encapsulated base" scheme. Consider: >>> class X(Base): ... pass >>> class Y(Base): ... pass >>> class Z(Base): ... pass >>> class C(X, Y, Z): ... def foo(self): ... return 42 When we look up an attribute, we do the following: - Look in C's dictionary first. - Look up the attribute in X. We don't care how we get the attribute from X. If X is a new-style-class, we use the new algorithm. If X is a classic class, we use left-to-right depth-first. If X is an nsEC, use the "encapsulated base" algorithm. If we don't find the attribute in X, look in Y and then in Z, using the same approach. This algorithm will produce backward compatible results, providing the equivalent of left-to-right depth-first for nsECs and classic classes. We'll actually do something less abstract. We'll use a simple algorthm to merge the __mro__ of the base classes, computing an __mro__ for classic classes using the left-to-right depth-first algorithm. We'll basically lay the mros end-to-end left-to-right and remove repeats, keeping the first occurence of each class. >>> [c.__name__ for c in C.__mro__] ['C', 'X', 'Y', 'Z', 'Base', 'object'] For backward-compatability's sake, we actually depart from the above description a bit. We always put Base and object last in the mro, as shown in the example above. The primary reason for this is that object provides a do-nothing __init__ method. It is common practice to mix a C-implemented base class that implements a few methods with a Python class that implements those methods and others. The idea is that the C implementation overrides selected methods in C, so the C subclass is listed first. Unfortunately, because all extension classes are required to subclass Base, and thus, object, the C subclass brings along the __init__ object from objects, which would hide any __init__ method provided by the Python mix-in. Base and object are special in that they are implied by their meta classes. For example, a new-style class always has object as an ancestor, even if it isn't listed as a base: >>> class O: ... __metaclass__ = type >>> [c.__name__ for c in O.__bases__] ['object'] >>> [c.__name__ for c in O.__mro__] ['O', 'object'] Similarly, Base is always an ancestor of an extension class: >>> class E: ... __metaclass__ = ExtensionClass >>> [c.__name__ for c in E.__bases__] ['Base'] >>> [c.__name__ for c in E.__mro__] ['E', 'Base', 'object'] Base and object are generally added soley to get a particular meta class. They aren't used to provide application functionality and really shouldn't be considered when reasoning about where attributes come from. They do provide some useful default functionality and should be included at the end of the mro. Here are more examples: >>> from ExtensionClass import Base >>> class NA(object): ... pass >>> class NB(NA): ... pass >>> class NC(NA): ... pass >>> class ND(NB, NC): ... pass >>> [c.__name__ for c in ND.__mro__] ['ND', 'NB', 'NC', 'NA', 'object'] >>> class EA(Base): ... pass >>> class EB(EA): ... pass >>> class EC(EA): ... pass >>> class ED(EB, EC): ... pass >>> [c.__name__ for c in ED.__mro__] ['ED', 'EB', 'EA', 'EC', 'Base', 'object'] >>> class EE(ED, ND): ... pass >>> [c.__name__ for c in EE.__mro__] ['EE', 'ED', 'EB', 'EA', 'EC', 'ND', 'NB', 'NC', 'NA', 'Base', 'object'] >>> class EF(ND, ED): ... pass >>> [c.__name__ for c in EF.__mro__] ['EF', 'ND', 'NB', 'NC', 'NA', 'ED', 'EB', 'EA', 'EC', 'Base', 'object'] >>> class CA: ... pass >>> class CB(CA): ... pass >>> class CC(CA): ... pass >>> class CD(CB, CC): ... pass >>> class ECD(Base, CD): ... pass >>> [c.__name__ for c in ECD.__mro__] ['ECD', 'CD', 'CB', 'CA', 'CC', 'Base', 'object'] >>> class CDE(CD, Base): ... pass >>> [c.__name__ for c in CDE.__mro__] ['CDE', 'CD', 'CB', 'CA', 'CC', 'Base', 'object'] >>> class CEND(CD, ED, ND): ... pass >>> [c.__name__ for c in CEND.__mro__] ['CEND', 'CD', 'CB', 'CA', 'CC', """ \ """'ED', 'EB', 'EA', 'EC', 'ND', 'NB', 'NC', 'NA', 'Base', 'object'] """ def test_avoiding___init__decoy_w_inheritedAttribute(): """ >>> class Decoy(Base): ... pass >>> class B(Base): ... def __init__(self, a, b): ... print '__init__', a, b >>> class C(Decoy, B): ... def __init__(self): ... print 'C init' ...

This extra member is a method chain ('PyMethodChain') containing a linked list of method definition ('PyMethodDef') lists. Method chains can be used to implement method inheritance in C. Most extensions don't use method chains, but simply define method lists, which are null-terminated arrays of method definitions. A macro, 'METHOD_CHAIN' is defined in 'ExtensionClass.h' that converts a method list to a method chain. (See the example below.) - Module functions that create new instances must be replaced by an '__init__' method that initializes, but does not create storage for instances. - The extension class must be initialized and exported to the module with:: PyExtensionClass_Export(d,"name",type); where 'name' is the module name and 'type' is the extension class type object. Attribute lookup Attribute lookup is performed by calling the base extension class 'getattr' operation for the base extension class that includes C data, or for the first base extension class, if none of the base extension classes include C data. 'ExtensionClass.h' defines a macro 'Py_FindAttrString' that can be used to find an object's attributes that are stored in the object's instance dictionary or in the object's class or base classes:: v = Py_FindAttrString(self,name); In addition, a macro is provided that replaces 'Py_FindMethod' calls with logic to perform the same sort of lookup that is provided by 'Py_FindAttrString'. Linking The extension class mechanism was designed to be useful with dynamically linked extension modules. Modules that implement extension classes do not have to be linked against an extension class library. The macro 'PyExtensionClass_Export' imports the 'ExtensionClass' module and uses objects imported from this module to initialize an extension class with necessary behavior. */ #ifndef EXTENSIONCLASS_H #define EXTENSIONCLASS_H #include "Python.h" #include "import.h" /* Declarations for objects of type ExtensionClass */ #define EC PyTypeObject #define PyExtensionClass PyTypeObject #define EXTENSIONCLASS_BINDABLE_FLAG 1 << 2 #define EXTENSIONCLASS_NOINSTDICT_FLAG 1 << 5 typedef struct { PyObject_HEAD } _emptyobject; static struct ExtensionClassCAPIstruct { /***************************************************************************** WARNING: THIS STRUCT IS PRIVATE TO THE EXTENSION CLASS INTERFACE IMPLEMENTATION AND IS SUBJECT TO CHANGE !!! *****************************************************************************/ PyObject *(*EC_findiattrs_)(PyObject *self, char *cname); int (*PyExtensionClass_Export_)(PyObject *dict, char *name, PyTypeObject *typ); PyObject *(*PyECMethod_New_)(PyObject *callable, PyObject *inst); PyExtensionClass *ECBaseType_; PyExtensionClass *ECExtensionClassType_; } *PyExtensionClassCAPI = NULL; #define ECBaseType (PyExtensionClassCAPI->ECBaseType_) #define ECExtensionClassType (PyExtensionClassCAPI->ECExtensionClassType_) /* Following are macros that are needed or useful for defining extension classes: */ /* This macro redefines Py_FindMethod to do attribute for an attribute name given by a C string lookup using extension class meta-data.

As a meta-class, ExtensionClass provides the following features: - Support for a class initialiser: >>> from ExtensionClass import ExtensionClass, Base >>> class C(Base): ... def __class_init__(self): ... print 'class init called' ... print self.__name__ ... def bar(self): ... return 'bar called' class init called C >>> c = C() >>> int(c.__class__ is C) 1 >>> int(c.__class__ is type(c)) 1 - Making sure that every instance of the meta-class has Base as a base class: >>> class X: ... __metaclass__ = ExtensionClass >>> Base in X.__mro__ 1 - Provide an inheritedAttribute method for looking up attributes in base classes: >>> class C2(C): ... def bar(*a): ... return C2.inheritedAttribute('bar')(*a), 42 class init called C2 >>> o = C2() >>> o.bar() ('bar called', 42) This is for compatability with old code. New code should use super instead. The base class, Base, exists mainly to support the __of__ protocol. The __of__ protocol is similar to __get__ except that __of__ is called when an implementor is retrieved from an instance as well as from a class: >>> class O(Base): ... def __of__(*a): ... return a >>> o1 = O() >>> o2 = O() >>> C.o1 = o1 >>> c.o2 = o2 >>> c.o1 == (o1, c) 1 >>> C.o1 == o1 1 >>> int(c.o2 == (o2, c)) 1 We accomplish this by making a class that implements __of__ a descriptor and treating all descriptor ExtensionClasses this way.

The basic idea is: I'll call this the "encapsulated base" scheme. Consider: >>> class X(Base): ... pass >>> class Y(Base): ... pass >>> class Z(Base): ... pass >>> class C(X, Y, Z): ... def foo(self): ... return 42 When we look up an attribute, we do the following: - Look in C's dictionary first. - Look up the attribute in X. We don't care how we get the attribute from X. If X is a new-style-class, we use the new algorithm. If X is a classic class, we use left-to-right depth-first. If X is an nsEC, use the "encapsulated base" algorithm. If we don't find the attribute in X, look in Y and then in Z, using the same approach. This algorithm will produce backward compatible results, providing the equivalent of left-to-right depth-first for nsECs and classic classes. We'll actually do something less abstract. We'll use a simple algorthm to merge the __mro__ of the base classes, computing an __mro__ for classic classes using the left-to-right depth-first algorithm. We'll basically lay the mros end-to-end left-to-right and remove repeats, keeping the first occurence of each class. >>> [c.__name__ for c in C.__mro__] ['C', 'X', 'Y', 'Z', 'Base', 'object'] For backward-compatability's sake, we actually depart from the above description a bit. We always put Base and object last in the mro, as shown in the example above. The primary reason for this is that object provides a do-nothing __init__ method. It is common practice to mix a C-implemented base class that implements a few methods with a Python class that implements those methods and others. The idea is that the C implementation overrides selected methods in C, so the C subclass is listed first. Unfortunately, because all extension classes are required to subclass Base, and thus, object, the C subclass brings along the __init__ object from objects, which would hide any __init__ method provided by the Python mix-in. Base and object are special in that they are implied by their meta classes. For example, a new-style class always has object as an ancestor, even if it isn't listed as a base: >>> class O: ... __metaclass__ = type >>> [c.__name__ for c in O.__bases__] ['object'] >>> [c.__name__ for c in O.__mro__] ['O', 'object'] Similarly, Base is always an ancestor of an extension class: >>> class E: ... __metaclass__ = ExtensionClass >>> [c.__name__ for c in E.__bases__] ['Base'] >>> [c.__name__ for c in E.__mro__] ['E', 'Base', 'object'] Base and object are generally added soley to get a particular meta class. They aren't used to provide application functionality and really shouldn't be considered when reasoning about where attributes come from. They do provide some useful default functionality and should be included at the end of the mro. Here are more examples: >>> from ExtensionClass import Base >>> class NA(object): ... pass >>> class NB(NA): ... pass >>> class NC(NA): ... pass >>> class ND(NB, NC): ... pass >>> [c.__name__ for c in ND.__mro__] ['ND', 'NB', 'NC', 'NA', 'object'] >>> class EA(Base): ... pass >>> class EB(EA): ... pass >>> class EC(EA): ... pass >>> class ED(EB, EC): ... pass >>> [c.__name__ for c in ED.__mro__] ['ED', 'EB', 'EA', 'EC', 'Base', 'object'] >>> class EE(ED, ND): ... pass >>> [c.__name__ for c in EE.__mro__] ['EE', 'ED', 'EB', 'EA', 'EC', 'ND', 'NB', 'NC', 'NA', 'Base', 'object'] >>> class EF(ND, ED): ... pass >>> [c.__name__ for c in EF.__mro__] ['EF', 'ND', 'NB', 'NC', 'NA', 'ED', 'EB', 'EA', 'EC', 'Base', 'object'] >>> class CA: ... pass >>> class CB(CA): ... pass >>> class CC(CA): ... pass >>> class CD(CB, CC): ... pass >>> class ECD(Base, CD): ... pass >>> [c.__name__ for c in ECD.__mro__] ['ECD', 'CD', 'CB', 'CA', 'CC', 'Base', 'object'] >>> class CDE(CD, Base): ... pass >>> [c.__name__ for c in CDE.__mro__] ['CDE', 'CD', 'CB', 'CA', 'CC', 'Base', 'object'] >>> class CEND(CD, ED, ND): ... pass >>> [c.__name__ for c in CEND.__mro__] ['CEND', 'CD', 'CB', 'CA', 'CC', """ \ """'ED', 'EB', 'EA', 'EC', 'ND', 'NB', 'NC', 'NA', 'Base', 'object'] """ def test_avoiding___init__decoy_w_inheritedAttribute(): """ >>> class Decoy(Base): ... pass >>> class B(Base): ... def __init__(self, a, b): ... print '__init__', a, b >>> class C(Decoy, B): ... def __init__(self): ... print 'C init' ...

This extra member is a method chain ('PyMethodChain') containing a linked list of method definition ('PyMethodDef') lists. Method chains can be used to implement method inheritance in C. Most extensions don't use method chains, but simply define method lists, which are null-terminated arrays of method definitions. A macro, 'METHOD_CHAIN' is defined in 'ExtensionClass.h' that converts a method list to a method chain. (See the example below.) - Module functions that create new instances must be replaced by an '__init__' method that initializes, but does not create storage for instances. - The extension class must be initialized and exported to the module with:: PyExtensionClass_Export(d,"name",type); where 'name' is the module name and 'type' is the extension class type object. Attribute lookup Attribute lookup is performed by calling the base extension class 'getattr' operation for the base extension class that includes C data, or for the first base extension class, if none of the base extension classes include C data. 'ExtensionClass.h' defines a macro 'Py_FindAttrString' that can be used to find an object's attributes that are stored in the object's instance dictionary or in the object's class or base classes:: v = Py_FindAttrString(self,name); In addition, a macro is provided that replaces 'Py_FindMethod' calls with logic to perform the same sort of lookup that is provided by 'Py_FindAttrString'. Linking The extension class mechanism was designed to be useful with dynamically linked extension modules. Modules that implement extension classes do not have to be linked against an extension class library. The macro 'PyExtensionClass_Export' imports the 'ExtensionClass' module and uses objects imported from this module to initialize an extension class with necessary behavior. */ #ifndef EXTENSIONCLASS_H #define EXTENSIONCLASS_H #include "Python.h" #include "import.h" /* Declarations for objects of type ExtensionClass */ #define EC PyTypeObject #define PyExtensionClass PyTypeObject #define EXTENSIONCLASS_BINDABLE_FLAG 1 << 2 #define EXTENSIONCLASS_NOINSTDICT_FLAG 1 << 5 typedef struct { PyObject_HEAD } _emptyobject; static struct ExtensionClassCAPIstruct { /***************************************************************************** WARNING: THIS STRUCT IS PRIVATE TO THE EXTENSION CLASS INTERFACE IMPLEMENTATION AND IS SUBJECT TO CHANGE !!! *****************************************************************************/ PyObject *(*EC_findiattrs_)(PyObject *self, char *cname); int (*PyExtensionClass_Export_)(PyObject *dict, char *name, PyTypeObject *typ); PyObject *(*PyECMethod_New_)(PyObject *callable, PyObject *inst); PyExtensionClass *ECBaseType_; PyExtensionClass *ECExtensionClassType_; } *PyExtensionClassCAPI = NULL; #define ECBaseType (PyExtensionClassCAPI->ECBaseType_) #define ECExtensionClassType (PyExtensionClassCAPI->ECExtensionClassType_) /* Following are macros that are needed or useful for defining extension classes: */ /* This macro redefines Py_FindMethod to do attribute for an attribute name given by a C string lookup using extension class meta-data.

Detailed Documentation ********************** ============================= Viewlets and Viewlet Managers ============================= Let's start with some motivation. Using content providers allows us to insert one piece of HTML content. In most Web development, however, you are often interested in defining some sort of region and then allow developers to register content for those regions. >>> from zope.viewlet import interfaces Design Notes ------------ As mentioned above, besides inserting snippets of HTML at places, we more frequently want to define a region in our page and allow specialized content providers to be inserted based on configuration. Those specialized content providers are known as viewlets and are only available inside viewlet managers, which are just a more complex example of content providers. Unfortunately, the Java world does not implement this layer separately. The viewlet manager is most similar to a Java "channel", but we decided against using this name, since it is very generic and not very meaningful. The viewlet has no Java counterpart, since Java does not implement content providers using a component architecture and thus does not register content providers specifically for viewlet managers, which I believe makes the Java implementation less useful as a generic concept. In fact, the main design goal in the Java world is the implementation of reusable and sharable portlets. The scope for Zope 3 is larger, since we want to provide a generic framework for building pluggable user interfaces. The Viewlet Manager ------------------- In this implementation of viewlets, those regions are just content providers called viewlet managers that manage a special type of content providers known as viewlets. Every viewlet manager handles the viewlets registered for it: >>> class ILeftColumn(interfaces.IViewletManager): ... """Viewlet manager located in the left column.""" You can then create a viewlet manager using this interface now: >>> from zope.viewlet import manager >>> LeftColumn = manager.ViewletManager('left', ILeftColumn) Now we have to instantiate it: >>> import zope.interface >>> class Content(object): ... zope.interface.implements(zope.interface.Interface) >>> content = Content() >>> from zope.publisher.browser import TestRequest >>> request = TestRequest() >>> from zope.publisher.interfaces.browser import IBrowserView >>> class View(object): ... zope.interface.implements(IBrowserView) ... def __init__(self, context, request): ... pass >>> view = View(content, request) >>> leftColumn = LeftColumn(content, request, view) So initially nothing gets rendered: >>> leftColumn.update() >>> leftColumn.render() u'' But now we register some viewlets for the manager >>> import zope.component >>> from zope.publisher.interfaces.browser import IDefaultBrowserLayer >>> class WeatherBox(object): ... zope.interface.implements(interfaces.IViewlet) ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... ... def update(self): ... pass ... ... def render(self): ... return u'
It is sunny today!
' >>> # Create a security checker for viewlets. >>> from zope.security.checker import NamesChecker, defineChecker >>> viewletChecker = NamesChecker(('update', 'render')) >>> defineChecker(WeatherBox, viewletChecker) >>> zope.component.provideAdapter( ... WeatherBox, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, ILeftColumn), ... interfaces.IViewlet, name='weather') >>> from zope.location.interfaces import ILocation >>> class SportBox(object): ... zope.interface.implements(interfaces.IViewlet, ... ILocation) ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... ... def update(self): ... pass ... ... def render(self): ... return u'
Patriots (23) : Steelers (7)
' >>> defineChecker(SportBox, viewletChecker) >>> zope.component.provideAdapter( ... SportBox, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, ILeftColumn), ... interfaces.IViewlet, name='sport') and thus the left column is filled. Note that also events get fired before viewlets are updated. We register a simple handler to demonstrate this behaviour. >>> from zope.contentprovider.interfaces import IBeforeUpdateEvent >>> events = [] >>> def handler(ev): ... events.append(ev) >>> zope.component.provideHandler(handler, (IBeforeUpdateEvent,)) >>> leftColumn.update() >>> [(ev, ev.object.__class__.__name__) for ev in events] [(, 'SportBox'), (, 'WeatherBox')] >>> print leftColumn.render()
Patriots (23) : Steelers (7)
It is sunny today!
But this is of course pretty lame, since there is no way of specifying how the viewlets are put together. But we have a solution. The second argument of the ``ViewletManager()`` function is a template in which we can specify how the viewlets are put together: >>> import os, tempfile >>> temp_dir = tempfile.mkdtemp() >>> leftColTemplate = os.path.join(temp_dir, 'leftCol.pt') >>> open(leftColTemplate, 'w').write(''' ...
... ...
... ''') >>> LeftColumn = manager.ViewletManager('left', ILeftColumn, ... template=leftColTemplate) >>> leftColumn = LeftColumn(content, request, view) TODO: Fix this silly thing; viewlets should be directly available. As you can see, the viewlet manager provides a global ``options/viewlets`` variable that is an iterable of all the available viewlets in the correct order: >>> leftColumn.update() >>> print leftColumn.render().strip()
Patriots (23) : Steelers (7)
It is sunny today!
If a viewlet provides ILocation the ``__name__`` attribute of the viewlet is set to the name under which the viewlet is registered. >>> [getattr(viewlet, '__name__', None) for viewlet in leftColumn.viewlets] [u'sport', None] You can also lookup the viewlets directly for management purposes: >>> leftColumn['weather'] >>> leftColumn.get('weather') The viewlet manager also provides the __contains__ method defined in IReadMapping: >>> 'weather' in leftColumn True >>> 'unknown' in leftColumn False If the viewlet is not found, then the expected behavior is provided: >>> leftColumn['stock'] Traceback (most recent call last): ... ComponentLookupError: No provider with name `stock` found. >>> leftColumn.get('stock') is None True Customizing the default Viewlet Manager --------------------------------------- One important feature of any viewlet manager is to be able to filter and sort the viewlets it is displaying. The default viewlet manager that we have been using in the tests above, supports filtering by access availability and sorting via the viewlet's ``__cmp__()`` method (default). You can easily override this default policy by providing a base viewlet manager class. In our case we will manage the viewlets using a global list: >>> shown = ['weather', 'sport'] The viewlet manager base class now uses this list: >>> class ListViewletManager(object): ... ... def filter(self, viewlets): ... viewlets = super(ListViewletManager, self).filter(viewlets) ... return [(name, viewlet) ... for name, viewlet in viewlets ... if name in shown] ... ... def sort(self, viewlets): ... viewlets = dict(viewlets) ... return [(name, viewlets[name]) for name in shown] Let's now create a new viewlet manager: >>> LeftColumn = manager.ViewletManager( ... 'left', ILeftColumn, bases=(ListViewletManager,), ... template=leftColTemplate) >>> leftColumn = LeftColumn(content, request, view) So we get the weather box first and the sport box second: >>> leftColumn.update() >>> print leftColumn.render().strip()
It is sunny today!
Patriots (23) : Steelers (7)
Now let's change the order... >>> shown.reverse() and the order should switch as well: >>> leftColumn.update() >>> print leftColumn.render().strip()
Patriots (23) : Steelers (7)
It is sunny today!
Of course, we also can remove a shown viewlet: >>> weather = shown.pop() >>> leftColumn.update() >>> print leftColumn.render().strip()
Patriots (23) : Steelers (7)
WeightOrderedViewletManager --------------------------- The weight ordered viewlet manager offers ordering viewlets by a additional weight argument. Viewlets which doesn't provide a weight attribute will get a weight of 0 (zero). Let's define a new column: >>> class IWeightedColumn(interfaces.IViewletManager): ... """Column with weighted viewlet manager.""" First register a template for the weight ordered viewlet manager: >>> weightedColTemplate = os.path.join(temp_dir, 'weightedColTemplate.pt') >>> open(weightedColTemplate, 'w').write(''' ...
... ...
... ''') And create a new weight ordered viewlet manager: >>> from zope.viewlet.manager import WeightOrderedViewletManager >>> WeightedColumn = manager.ViewletManager( ... 'left', IWeightedColumn, bases=(WeightOrderedViewletManager,), ... template=weightedColTemplate) >>> weightedColumn = WeightedColumn(content, request, view) Let's create some viewlets: >>> from zope.viewlet import viewlet >>> class FirstViewlet(viewlet.ViewletBase): ... ... weight = 1 ... ... def render(self): ... return u'
first
' >>> class SecondViewlet(viewlet.ViewletBase): ... ... weight = 2 ... ... def render(self): ... return u'
second
' >>> class ThirdViewlet(viewlet.ViewletBase): ... ... weight = 3 ... ... def render(self): ... return u'
third
' >>> class UnWeightedViewlet(viewlet.ViewletBase): ... ... def render(self): ... return u'
unweighted
' >>> defineChecker(FirstViewlet, viewletChecker) >>> defineChecker(SecondViewlet, viewletChecker) >>> defineChecker(ThirdViewlet, viewletChecker) >>> defineChecker(UnWeightedViewlet, viewletChecker) >>> zope.component.provideAdapter( ... ThirdViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='third') >>> zope.component.provideAdapter( ... FirstViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='first') >>> zope.component.provideAdapter( ... SecondViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='second') >>> zope.component.provideAdapter( ... UnWeightedViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='unweighted') And check the order: >>> weightedColumn.update() >>> print weightedColumn.render().strip()

ConditionalViewletManager ------------------------- The conditional ordered viewlet manager offers ordering viewlets by a additional weight argument and filters by the available attribute if a supported by the viewlet. Viewlets which doesn't provide a available attribute will not get skipped. The default weight value for viewlets which doesn't provide a weight attribute is 0 (zero). Let's define a new column: >>> class IConditionalColumn(interfaces.IViewletManager): ... """Column with weighted viewlet manager.""" First register a template for the weight ordered viewlet manager: >>> conditionalColTemplate = os.path.join(temp_dir, ... 'conditionalColTemplate.pt') >>> open(conditionalColTemplate, 'w').write(''' ...
... ...
... ''') And create a new conditional viewlet manager: >>> from zope.viewlet.manager import ConditionalViewletManager >>> ConditionalColumn = manager.ViewletManager( ... 'left', IConditionalColumn, bases=(ConditionalViewletManager,), ... template=conditionalColTemplate) >>> conditionalColumn = ConditionalColumn(content, request, view) Let's create some viewlets. We also use the previous viewlets supporting no weight and or no available attribute: >>> from zope.viewlet import viewlet >>> class AvailableViewlet(viewlet.ViewletBase): ... ... weight = 4 ... ... available = True ... ... def render(self): ... return u'
available
' >>> class UnAvailableViewlet(viewlet.ViewletBase): ... ... weight = 5 ... ... available = False ... ... def render(self): ... return u'
not available
' >>> defineChecker(AvailableViewlet, viewletChecker) >>> defineChecker(UnAvailableViewlet, viewletChecker) >>> zope.component.provideAdapter( ... ThirdViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='third') >>> zope.component.provideAdapter( ... FirstViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='first') >>> zope.component.provideAdapter( ... SecondViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='second') >>> zope.component.provideAdapter( ... UnWeightedViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='unweighted') >>> zope.component.provideAdapter( ... AvailableViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='available') >>> zope.component.provideAdapter( ... UnAvailableViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='unavailable') And check the order: >>> conditionalColumn.update() >>> print conditionalColumn.render().strip()

Viewlet Base Classes -------------------- To make the creation of viewlets simpler, a set of useful base classes and helper functions are provided. The first class is a base class that simply defines the constructor: >>> base = viewlet.ViewletBase('context', 'request', 'view', 'manager') >>> base.context 'context' >>> base.request 'request' >>> base.__parent__ 'view' >>> base.manager 'manager' But a default ``render()`` method implementation is not provided: >>> base.render() Traceback (most recent call last): ... NotImplementedError: `render` method must be implemented by subclass. If you have already an existing class that produces the HTML content in some method, then the ``SimpleAttributeViewlet`` might be for you, since it can be used to convert any class quickly into a viewlet: >>> class FooViewlet(viewlet.SimpleAttributeViewlet): ... __page_attribute__ = 'foo' ... ... def foo(self): ... return 'output' The `__page_attribute__` attribute provides the name of the function to call for rendering. >>> foo = FooViewlet('context', 'request', 'view', 'manager') >>> foo.foo() 'output' >>> foo.render() 'output' If you specify `render` as the attribute an error is raised to prevent infinite recursion: >>> foo.__page_attribute__ = 'render' >>> foo.render() Traceback (most recent call last): ... AttributeError: render The same is true if the specified attribute does not exist: >>> foo.__page_attribute__ = 'bar' >>> foo.render() Traceback (most recent call last): ... AttributeError: 'FooViewlet' object has no attribute 'bar' To create simple template-based viewlets you can use the ``SimpleViewletClass()`` function. This function is very similar to its view equivalent and is used by the ZCML directives to create viewlets. The result of this function call will be a fully functional viewlet class. Let's start by simply specifying a template only: >>> template = os.path.join(temp_dir, 'demoTemplate.pt') >>> open(template, 'w').write('''
contents
''') >>> Demo = viewlet.SimpleViewletClass(template) >>> print Demo(content, request, view, manager).render()
contents
Now let's additionally specify a class that can provide additional features: >>> class MyViewlet(object): ... myAttribute = 8 >>> Demo = viewlet.SimpleViewletClass(template, bases=(MyViewlet,)) >>> MyViewlet in Demo.__bases__ True >>> Demo(content, request, view, manager).myAttribute 8 The final important feature is the ability to pass in further attributes to the class: >>> Demo = viewlet.SimpleViewletClass( ... template, attributes={'here': 'now', 'lucky': 3}) >>> demo = Demo(content, request, view, manager) >>> demo.here 'now' >>> demo.lucky 3 As for all views, they must provide a name that can also be passed to the function: >>> Demo = viewlet.SimpleViewletClass(template, name='demoViewlet') >>> demo = Demo(content, request, view, manager) >>> demo.__name__ 'demoViewlet' In addition to the the generic viewlet code above, the package comes with two viewlet base classes and helper functions for inserting CSS and Javascript links into HTML headers, since those two are so very common. I am only going to demonstrate the helper functions here, since those demonstrations will fully demonstrate the functionality of the base classes as well. The viewlet will look up the resource it was given and tries to produce the absolute URL for it: >>> class JSResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/resource.js' >>> zope.component.provideAdapter( ... JSResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='resource.js') >>> JSViewlet = viewlet.JavaScriptViewlet('resource.js') >>> print JSViewlet(content, request, view, manager).render().strip() There is also a javascript viewlet base class which knows how to render more then one javascript resource file: >>> class JSSecondResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/second-resource.js' >>> zope.component.provideAdapter( ... JSSecondResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='second-resource.js') >>> JSBundleViewlet = viewlet.JavaScriptBundleViewlet(('resource.js', ... 'second-resource.js')) >>> print JSBundleViewlet(content, request, view, manager).render().strip() The same works for the CSS resource viewlet: >>> class CSSResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/resource.css' >>> zope.component.provideAdapter( ... CSSResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='resource.css') >>> CSSViewlet = viewlet.CSSViewlet('resource.css') >>> print CSSViewlet(content, request, view, manager).render().strip() You can also change the media type and the rel attribute: >>> CSSViewlet = viewlet.CSSViewlet('resource.css', media='print', rel='css') >>> print CSSViewlet(content, request, view, manager).render().strip() There is also a bundle viewlet for CSS links: >>> class CSSPrintResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/print-resource.css' >>> zope.component.provideAdapter( ... CSSPrintResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='print-resource.css') >>> items = [] >>> items.append({'path':'resource.css', 'rel':'stylesheet', 'media':'all'}) >>> items.append({'path':'print-resource.css', 'media':'print'}) >>> CSSBundleViewlet = viewlet.CSSBundleViewlet(items) >>> print CSSBundleViewlet(content, request, view, manager).render().strip() A Complex Example ----------------- The Data ~~~~~~~~ So far we have only demonstrated simple (maybe overly trivial) use cases of the viewlet system. In the following example, we are going to develop a generic contents view for files. The step is to create a file component: >>> class IFile(zope.interface.Interface): ... data = zope.interface.Attribute('Data of file.') >>> class File(object): ... zope.interface.implements(IFile) ... def __init__(self, data=''): ... self.__name__ = '' ... self.data = data Since we want to also provide the size of a file, here a simple implementation of the ``ISized`` interface: >>> from zope import size >>> class FileSized(object): ... zope.interface.implements(size.interfaces.ISized) ... zope.component.adapts(IFile) ... ... def __init__(self, file): ... self.file = file ... ... def sizeForSorting(self): ... return 'byte', len(self.file.data) ... ... def sizeForDisplay(self): ... return '%i bytes' %len(self.file.data) >>> zope.component.provideAdapter(FileSized) We also need a container to which we can add files: >>> class Container(dict): ... def __setitem__(self, name, value): ... value.__name__ = name ... super(Container, self).__setitem__(name, value) Here is some sample data: >>> container = Container() >>> container['test.txt'] = File('Hello World!') >>> container['mypage.html'] = File('Hello World!') >>> container['data.xml'] = File('Hello World!') The View ~~~~~~~~ The contents view of the container should iterate through the container and represent the files in a table: >>> contentsTemplate = os.path.join(temp_dir, 'contents.pt') >>> open(contentsTemplate, 'w').write(''' ... ... ...

Contents

...
... ... ... ''') >>> from zope.browserpage.simpleviewclass import SimpleViewClass >>> Contents = SimpleViewClass(contentsTemplate, name='contents.html') The Viewlet Manager ~~~~~~~~~~~~~~~~~~~ Now we have to write our own viewlet manager. In this case we cannot use the default implementation, since the viewlets will be looked up for each different item: >>> shownColumns = [] >>> class ContentsViewletManager(object): ... zope.interface.implements(interfaces.IViewletManager) ... index = None ... ... def __init__(self, context, request, view): ... self.context = context ... self.request = request ... self.__parent__ = view ... ... def update(self): ... rows = [] ... for name, value in self.context.items(): ... rows.append( ... [zope.component.getMultiAdapter( ... (value, self.request, self.__parent__, self), ... interfaces.IViewlet, name=colname) ... for colname in shownColumns]) ... [entry.update() for entry in rows[-1]] ... self.rows = rows ... ... def render(self, *args, **kw): ... return self.index(*args, **kw) Now we need a template to produce the contents table: >>> tableTemplate = os.path.join(temp_dir, 'table.pt') >>> open(tableTemplate, 'w').write(''' ... ... ... ... ...
... ...
... ''') From the two pieces above, we can generate the final viewlet manager class and register it (it's a bit tedious, I know): >>> from zope.browserpage import ViewPageTemplateFile >>> ContentsViewletManager = type( ... 'ContentsViewletManager', (ContentsViewletManager,), ... {'index': ViewPageTemplateFile(tableTemplate)}) >>> zope.component.provideAdapter( ... ContentsViewletManager, ... (Container, IDefaultBrowserLayer, zope.interface.Interface), ... interfaces.IViewletManager, name='contents') Since we have not defined any viewlets yet, the table is totally empty: >>> contents = Contents(container, request) >>> print contents().strip()

Contents

The Viewlets and the Final Result ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Now let's create a first viewlet for the manager... >>> class NameViewlet(object): ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... self.context = context ... ... def update(self): ... pass ... ... def render(self): ... return self.context.__name__ and register it: >>> zope.component.provideAdapter( ... NameViewlet, ... (IFile, IDefaultBrowserLayer, ... zope.interface.Interface, interfaces.IViewletManager), ... interfaces.IViewlet, name='name') Note how you register the viewlet on ``IFile`` and not on the container. Now we should be able to see the name for each file in the container: >>> print contents().strip()

Contents

Waaa, nothing there! What happened? Well, we have to tell our user preferences that we want to see the name as a column in the table: >>> shownColumns = ['name'] >>> print contents().strip()

Contents

mypage.html
data.xml
test.txt
Let's now write a second viewlet that will display the size of the object for us: >>> class SizeViewlet(object): ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... self.context = context ... ... def update(self): ... pass ... ... def render(self): ... return size.interfaces.ISized(self.context).sizeForDisplay() >>> zope.component.provideAdapter( ... SizeViewlet, ... (IFile, IDefaultBrowserLayer, ... zope.interface.Interface, interfaces.IViewletManager), ... interfaces.IViewlet, name='size') After we added it to the list of shown columns, >>> shownColumns = ['name', 'size'] we can see an entry for it: >>> print contents().strip()

Contents

mypage.html 38 bytes
data.xml 31 bytes
test.txt 12 bytes
If we switch the two columns around, >>> shownColumns = ['size', 'name'] the result will be >>> print contents().strip()

Contents

38 bytes mypage.html
31 bytes data.xml
12 bytes test.txt
Supporting Sorting ~~~~~~~~~~~~~~~~~~ Oftentimes you also want to batch and sort the entries in a table. Since those two features are not part of the view logic, they should be treated with independent components. In this example, we are going to only implement sorting using a simple utility: >>> class ISorter(zope.interface.Interface): ... ... def sort(values): ... """Sort the values.""" >>> class SortByName(object): ... zope.interface.implements(ISorter) ... ... def sort(self, values): ... return sorted(values, lambda x, y: cmp(x.__name__, y.__name__)) >>> zope.component.provideUtility(SortByName(), name='name') >>> class SortBySize(object): ... zope.interface.implements(ISorter) ... ... def sort(self, values): ... return sorted( ... values, ... lambda x, y: cmp(size.interfaces.ISized(x).sizeForSorting(), ... size.interfaces.ISized(y).sizeForSorting())) >>> zope.component.provideUtility(SortBySize(), name='size') Note that we decided to give the sorter utilities the same name as the corresponding viewlet. This convention will make our implementation of the viewlet manager much simpler: >>> sortByColumn = '' >>> class SortedContentsViewletManager(object): ... zope.interface.implements(interfaces.IViewletManager) ... index = None ... ... def __init__(self, context, request, view): ... self.context = context ... self.request = request ... self.__parent__ = view ... ... def update(self): ... values = self.context.values() ... ... if sortByColumn: ... sorter = zope.component.queryUtility(ISorter, sortByColumn) ... if sorter: ... values = sorter.sort(values) ... ... rows = [] ... for value in values: ... rows.append( ... [zope.component.getMultiAdapter( ... (value, self.request, self.__parent__, self), ... interfaces.IViewlet, name=colname) ... for colname in shownColumns]) ... [entry.update() for entry in rows[-1]] ... self.rows = rows ... ... def render(self, *args, **kw): ... return self.index(*args, **kw) As you can see, the concern of sorting is cleanly separated from generating the view code. In MVC terms that means that the controller (sort) is logically separated from the view (viewlets). Let's now do the registration dance for the new viewlet manager. We simply override the existing registration: >>> SortedContentsViewletManager = type( ... 'SortedContentsViewletManager', (SortedContentsViewletManager,), ... {'index': ViewPageTemplateFile(tableTemplate)}) >>> zope.component.provideAdapter( ... SortedContentsViewletManager, ... (Container, IDefaultBrowserLayer, zope.interface.Interface), ... interfaces.IViewletManager, name='contents') Finally we sort the contents by name: >>> shownColumns = ['name', 'size'] >>> sortByColumn = 'name' >>> print contents().strip()

Now let's sort by size: >>> sortByColumn = 'size' >>> print contents().strip()

That's it! As you can see, in a few steps we have built a pretty flexible contents view with selectable columns and sorting. However, there is a lot of room for extending this example: - Table Header: The table header cell for each column should be a different type of viewlet, but registered under the same name. The column header viewlet also adapts the container not the item. The header column should also be able to control the sorting. - Batching: A simple implementation of batching should work very similar to the sorting feature. Of course, efficient implementations should somehow combine batching and sorting more effectively. - Sorting in ascending and descending order: Currently, you can only sort from the smallest to the highest value; however, this limitation is almost superficial and can easily be removed by making the sorters a bit more flexible. - Further Columns: For a real application, you would want to implement other columns, of course. You would also probably want some sort of fallback for the case that a viewlet is not found for a particular container item and column. Cleanup ------- >>> import shutil >>> shutil.rmtree(temp_dir) ================================ The ``viewletManager`` Directive ================================ The ``viewletManager`` directive allows you to quickly register a new viewlet manager without worrying about the details of the ``adapter`` directive. Before we can use the directives, we have to register their handlers by executing the package's meta configuration: >>> from zope.configuration import xmlconfig >>> context = xmlconfig.string(''' ... ... ... ... ''') Now we can register a viewlet manager: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Let's make sure the directive has really issued a sensible adapter registration; to do that, we create some dummy content, request and view objects: >>> import zope.interface >>> class Content(object): ... zope.interface.implements(zope.interface.Interface) >>> content = Content() >>> from zope.publisher.browser import TestRequest >>> request = TestRequest() >>> from zope.publisher.browser import BrowserView >>> view = BrowserView(content, request) Now let's lookup the manager. This particular registration is pretty boring: >>> import zope.component >>> from zope.viewlet import interfaces >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ... interfaces.IViewletManager, name='defaultmanager') >>> manager object ...> >>> interfaces.IViewletManager.providedBy(manager) True >>> manager.template is None True >>> manager.update() >>> manager.render() u'' However, this registration is not very useful, since we did specify a specific viewlet manager interface, a specific content interface, specific view or specific layer. This means that all viewlets registered will be found. The first step to effectively using the viewlet manager directive is to define a special viewlet manager interface: >>> class ILeftColumn(interfaces.IViewletManager): ... """Left column of my page.""" Now we can register register a manager providing this interface: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> ILeftColumn.providedBy(manager) True >>> manager.template is None True >>> manager.update() >>> manager.render() u'' Next let's see what happens, if we specify a template for the viewlet manager: >>> import os, tempfile >>> temp_dir = tempfile.mkdtemp() >>> leftColumnTemplate = os.path.join(temp_dir, 'leftcolumn.pt') >>> open(leftColumnTemplate, 'w').write(''' ...
...
...
... ''') >>> context = xmlconfig.string(''' ... ... ... ... ''' %leftColumnTemplate, context=context) >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> ILeftColumn.providedBy(manager) True >>> manager.template ...>> >>> manager.update() >>> print manager.render().strip()
Additionally you can specify a class that will serve as a base to the default viewlet manager or be a viewlet manager in its own right. In our case we will provide a custom implementation of the ``sort()`` method, which will sort by a weight attribute in the viewlet: >>> class WeightBasedSorting(object): ... def sort(self, viewlets): ... return sorted(viewlets, ... lambda x, y: cmp(x[1].weight, y[1].weight)) >>> context = xmlconfig.string(''' ... ... ... ... ''' %leftColumnTemplate, context=context) >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> manager.__class__.__bases__ (, ) >>> ILeftColumn.providedBy(manager) True >>> manager.template ...>> >>> manager.update() >>> print manager.render().strip()
Finally, if a non-existent template is specified, an error is raised: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 3.2-7.8 ConfigurationError: ('No such file', '...foo.pt') ========================= The ``viewlet`` Directive ========================= Now that we have a viewlet manager, we have to register some viewlets for it. The ``viewlet`` directive is similar to the ``viewletManager`` directive, except that the viewlet is also registered for a particular manager interface, as seen below: >>> weatherTemplate = os.path.join(temp_dir, 'weather.pt') >>> open(weatherTemplate, 'w').write(''' ...
sunny
... ''') >>> context = xmlconfig.string(''' ... ... ... ... ''' % weatherTemplate, context=context) If we look into the adapter registry, we will find the viewlet: >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='weather') >>> viewlet.render().strip() u'
sunny
' >>> viewlet.extra_string_attributes u'can be specified' The manager now also gives us the output of the one and only viewlet: >>> manager.update() >>> print manager.render().strip()
sunny
Let's now ensure that we can also specify a viewlet class: >>> class Weather(object): ... weight = 0 >>> context = xmlconfig.string(''' ... ... ... ... ''' % weatherTemplate, context=context) >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='weather2') >>> viewlet().strip() u'
sunny
' Okay, so the template-driven cases work. But just specifying a class should also work: >>> class Sport(object): ... weight = 0 ... def __call__(self): ... return u'Red Sox vs. White Sox' >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, name='sport') >>> viewlet() u'Red Sox vs. White Sox' It should also be possible to specify an alternative attribute of the class to be rendered upon calling the viewlet: >>> class Stock(object): ... weight = 0 ... def getStockTicker(self): ... return u'SRC $5.19' >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='stock') >>> viewlet.render() u'SRC $5.19' A final feature the ``viewlet`` directive is that it supports the specification of any number of keyword arguments: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='stock2') >>> viewlet.weight u'8' Error Scenarios --------------- Neither the class or template have been specified: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 3.2-7.8 ConfigurationError: Must specify a class or template The specified attribute is not ``__call__``, but also a template has been specified: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 3.2-9.8 ConfigurationError: Attribute and template cannot be used together. Now, we are not specifying a template, but a class that does not have the specified attribute: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 3.2-9.8 ConfigurationError: The provided class doesn't have the specified attribute Cleanup ------- >>> import shutil >>> shutil.rmtree(temp_dir) ======= CHANGES ======= 3.7.2 (2010-05-25) ------------------ - Fixed unit tests broken under Python 2.4 by the switch to the standard library ``doctest`` module. 3.7.1 (2010-04-30) ------------------ - Removed use of 'zope.testing.doctest' in favor of stdlib's 'doctest. - Fixed dubious quoting in metadirectives.py.

Detailed Documentation ********************** ============================= Viewlets and Viewlet Managers ============================= Let's start with some motivation. Using content providers allows us to insert one piece of HTML content. In most Web development, however, you are often interested in defining some sort of region and then allow developers to register content for those regions. >>> from zope.viewlet import interfaces Design Notes ------------ As mentioned above, besides inserting snippets of HTML at places, we more frequently want to define a region in our page and allow specialized content providers to be inserted based on configuration. Those specialized content providers are known as viewlets and are only available inside viewlet managers, which are just a more complex example of content providers. Unfortunately, the Java world does not implement this layer separately. The viewlet manager is most similar to a Java "channel", but we decided against using this name, since it is very generic and not very meaningful. The viewlet has no Java counterpart, since Java does not implement content providers using a component architecture and thus does not register content providers specifically for viewlet managers, which I believe makes the Java implementation less useful as a generic concept. In fact, the main design goal in the Java world is the implementation of reusable and sharable portlets. The scope for Zope 3 is larger, since we want to provide a generic framework for building pluggable user interfaces. The Viewlet Manager ------------------- In this implementation of viewlets, those regions are just content providers called viewlet managers that manage a special type of content providers known as viewlets. Every viewlet manager handles the viewlets registered for it: >>> class ILeftColumn(interfaces.IViewletManager): ... """Viewlet manager located in the left column.""" You can then create a viewlet manager using this interface now: >>> from zope.viewlet import manager >>> LeftColumn = manager.ViewletManager('left', ILeftColumn) Now we have to instantiate it: >>> import zope.interface >>> class Content(object): ... zope.interface.implements(zope.interface.Interface) >>> content = Content() >>> from zope.publisher.browser import TestRequest >>> request = TestRequest() >>> from zope.publisher.interfaces.browser import IBrowserView >>> class View(object): ... zope.interface.implements(IBrowserView) ... def __init__(self, context, request): ... pass >>> view = View(content, request) >>> leftColumn = LeftColumn(content, request, view) So initially nothing gets rendered: >>> leftColumn.update() >>> leftColumn.render() u'' But now we register some viewlets for the manager >>> import zope.component >>> from zope.publisher.interfaces.browser import IDefaultBrowserLayer >>> class WeatherBox(object): ... zope.interface.implements(interfaces.IViewlet) ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... ... def update(self): ... pass ... ... def render(self): ... return u'

' >>> # Create a security checker for viewlets. >>> from zope.security.checker import NamesChecker, defineChecker >>> viewletChecker = NamesChecker(('update', 'render')) >>> defineChecker(WeatherBox, viewletChecker) >>> zope.component.provideAdapter( ... WeatherBox, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, ILeftColumn), ... interfaces.IViewlet, name='weather') >>> from zope.location.interfaces import ILocation >>> class SportBox(object): ... zope.interface.implements(interfaces.IViewlet, ... ILocation) ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... ... def update(self): ... pass ... ... def render(self): ... return u'

' >>> defineChecker(SportBox, viewletChecker) >>> zope.component.provideAdapter( ... SportBox, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, ILeftColumn), ... interfaces.IViewlet, name='sport') and thus the left column is filled. Note that also events get fired before viewlets are updated. We register a simple handler to demonstrate this behaviour. >>> from zope.contentprovider.interfaces import IBeforeUpdateEvent >>> events = [] >>> def handler(ev): ... events.append(ev) >>> zope.component.provideHandler(handler, (IBeforeUpdateEvent,)) >>> leftColumn.update() >>> [(ev, ev.object.__class__.__name__) for ev in events] [(, 'SportBox'), (, 'WeatherBox')] >>> print leftColumn.render()

It is sunny today!
But this is of course pretty lame, since there is no way of specifying how the viewlets are put together. But we have a solution. The second argument of the ``ViewletManager()`` function is a template in which we can specify how the viewlets are put together: >>> import os, tempfile >>> temp_dir = tempfile.mkdtemp() >>> leftColTemplate = os.path.join(temp_dir, 'leftCol.pt') >>> open(leftColTemplate, 'w').write(''' ...
... ...
... ''') >>> LeftColumn = manager.ViewletManager('left', ILeftColumn, ... template=leftColTemplate) >>> leftColumn = LeftColumn(content, request, view) TODO: Fix this silly thing; viewlets should be directly available. As you can see, the viewlet manager provides a global ``options/viewlets`` variable that is an iterable of all the available viewlets in the correct order: >>> leftColumn.update() >>> print leftColumn.render().strip()
Patriots (23) : Steelers (7)
It is sunny today!
If a viewlet provides ILocation the ``__name__`` attribute of the viewlet is set to the name under which the viewlet is registered. >>> [getattr(viewlet, '__name__', None) for viewlet in leftColumn.viewlets] [u'sport', None] You can also lookup the viewlets directly for management purposes: >>> leftColumn['weather'] >>> leftColumn.get('weather') The viewlet manager also provides the __contains__ method defined in IReadMapping: >>> 'weather' in leftColumn True >>> 'unknown' in leftColumn False If the viewlet is not found, then the expected behavior is provided: >>> leftColumn['stock'] Traceback (most recent call last): ... ComponentLookupError: No provider with name `stock` found. >>> leftColumn.get('stock') is None True Customizing the default Viewlet Manager --------------------------------------- One important feature of any viewlet manager is to be able to filter and sort the viewlets it is displaying. The default viewlet manager that we have been using in the tests above, supports filtering by access availability and sorting via the viewlet's ``__cmp__()`` method (default). You can easily override this default policy by providing a base viewlet manager class. In our case we will manage the viewlets using a global list: >>> shown = ['weather', 'sport'] The viewlet manager base class now uses this list: >>> class ListViewletManager(object): ... ... def filter(self, viewlets): ... viewlets = super(ListViewletManager, self).filter(viewlets) ... return [(name, viewlet) ... for name, viewlet in viewlets ... if name in shown] ... ... def sort(self, viewlets): ... viewlets = dict(viewlets) ... return [(name, viewlets[name]) for name in shown] Let's now create a new viewlet manager: >>> LeftColumn = manager.ViewletManager( ... 'left', ILeftColumn, bases=(ListViewletManager,), ... template=leftColTemplate) >>> leftColumn = LeftColumn(content, request, view) So we get the weather box first and the sport box second: >>> leftColumn.update() >>> print leftColumn.render().strip()
It is sunny today!
Patriots (23) : Steelers (7)
Now let's change the order... >>> shown.reverse() and the order should switch as well: >>> leftColumn.update() >>> print leftColumn.render().strip()
Patriots (23) : Steelers (7)
It is sunny today!
Of course, we also can remove a shown viewlet: >>> weather = shown.pop() >>> leftColumn.update() >>> print leftColumn.render().strip()
Patriots (23) : Steelers (7)
WeightOrderedViewletManager --------------------------- The weight ordered viewlet manager offers ordering viewlets by a additional weight argument. Viewlets which doesn't provide a weight attribute will get a weight of 0 (zero). Let's define a new column: >>> class IWeightedColumn(interfaces.IViewletManager): ... """Column with weighted viewlet manager.""" First register a template for the weight ordered viewlet manager: >>> weightedColTemplate = os.path.join(temp_dir, 'weightedColTemplate.pt') >>> open(weightedColTemplate, 'w').write(''' ...
... ...
... ''') And create a new weight ordered viewlet manager: >>> from zope.viewlet.manager import WeightOrderedViewletManager >>> WeightedColumn = manager.ViewletManager( ... 'left', IWeightedColumn, bases=(WeightOrderedViewletManager,), ... template=weightedColTemplate) >>> weightedColumn = WeightedColumn(content, request, view) Let's create some viewlets: >>> from zope.viewlet import viewlet >>> class FirstViewlet(viewlet.ViewletBase): ... ... weight = 1 ... ... def render(self): ... return u'
first
' >>> class SecondViewlet(viewlet.ViewletBase): ... ... weight = 2 ... ... def render(self): ... return u'
second
' >>> class ThirdViewlet(viewlet.ViewletBase): ... ... weight = 3 ... ... def render(self): ... return u'
third
' >>> class UnWeightedViewlet(viewlet.ViewletBase): ... ... def render(self): ... return u'
unweighted
' >>> defineChecker(FirstViewlet, viewletChecker) >>> defineChecker(SecondViewlet, viewletChecker) >>> defineChecker(ThirdViewlet, viewletChecker) >>> defineChecker(UnWeightedViewlet, viewletChecker) >>> zope.component.provideAdapter( ... ThirdViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='third') >>> zope.component.provideAdapter( ... FirstViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='first') >>> zope.component.provideAdapter( ... SecondViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='second') >>> zope.component.provideAdapter( ... UnWeightedViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='unweighted') And check the order: >>> weightedColumn.update() >>> print weightedColumn.render().strip()

ConditionalViewletManager ------------------------- The conditional ordered viewlet manager offers ordering viewlets by a additional weight argument and filters by the available attribute if a supported by the viewlet. Viewlets which doesn't provide a available attribute will not get skipped. The default weight value for viewlets which doesn't provide a weight attribute is 0 (zero). Let's define a new column: >>> class IConditionalColumn(interfaces.IViewletManager): ... """Column with weighted viewlet manager.""" First register a template for the weight ordered viewlet manager: >>> conditionalColTemplate = os.path.join(temp_dir, ... 'conditionalColTemplate.pt') >>> open(conditionalColTemplate, 'w').write(''' ...
... ...
... ''') And create a new conditional viewlet manager: >>> from zope.viewlet.manager import ConditionalViewletManager >>> ConditionalColumn = manager.ViewletManager( ... 'left', IConditionalColumn, bases=(ConditionalViewletManager,), ... template=conditionalColTemplate) >>> conditionalColumn = ConditionalColumn(content, request, view) Let's create some viewlets. We also use the previous viewlets supporting no weight and or no available attribute: >>> from zope.viewlet import viewlet >>> class AvailableViewlet(viewlet.ViewletBase): ... ... weight = 4 ... ... available = True ... ... def render(self): ... return u'
available
' >>> class UnAvailableViewlet(viewlet.ViewletBase): ... ... weight = 5 ... ... available = False ... ... def render(self): ... return u'
not available
' >>> defineChecker(AvailableViewlet, viewletChecker) >>> defineChecker(UnAvailableViewlet, viewletChecker) >>> zope.component.provideAdapter( ... ThirdViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='third') >>> zope.component.provideAdapter( ... FirstViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='first') >>> zope.component.provideAdapter( ... SecondViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='second') >>> zope.component.provideAdapter( ... UnWeightedViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='unweighted') >>> zope.component.provideAdapter( ... AvailableViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='available') >>> zope.component.provideAdapter( ... UnAvailableViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='unavailable') And check the order: >>> conditionalColumn.update() >>> print conditionalColumn.render().strip()

Viewlet Base Classes -------------------- To make the creation of viewlets simpler, a set of useful base classes and helper functions are provided. The first class is a base class that simply defines the constructor: >>> base = viewlet.ViewletBase('context', 'request', 'view', 'manager') >>> base.context 'context' >>> base.request 'request' >>> base.__parent__ 'view' >>> base.manager 'manager' But a default ``render()`` method implementation is not provided: >>> base.render() Traceback (most recent call last): ... NotImplementedError: `render` method must be implemented by subclass. If you have already an existing class that produces the HTML content in some method, then the ``SimpleAttributeViewlet`` might be for you, since it can be used to convert any class quickly into a viewlet: >>> class FooViewlet(viewlet.SimpleAttributeViewlet): ... __page_attribute__ = 'foo' ... ... def foo(self): ... return 'output' The `__page_attribute__` attribute provides the name of the function to call for rendering. >>> foo = FooViewlet('context', 'request', 'view', 'manager') >>> foo.foo() 'output' >>> foo.render() 'output' If you specify `render` as the attribute an error is raised to prevent infinite recursion: >>> foo.__page_attribute__ = 'render' >>> foo.render() Traceback (most recent call last): ... AttributeError: render The same is true if the specified attribute does not exist: >>> foo.__page_attribute__ = 'bar' >>> foo.render() Traceback (most recent call last): ... AttributeError: 'FooViewlet' object has no attribute 'bar' To create simple template-based viewlets you can use the ``SimpleViewletClass()`` function. This function is very similar to its view equivalent and is used by the ZCML directives to create viewlets. The result of this function call will be a fully functional viewlet class. Let's start by simply specifying a template only: >>> template = os.path.join(temp_dir, 'demoTemplate.pt') >>> open(template, 'w').write('''
contents
''') >>> Demo = viewlet.SimpleViewletClass(template) >>> print Demo(content, request, view, manager).render()
contents
Now let's additionally specify a class that can provide additional features: >>> class MyViewlet(object): ... myAttribute = 8 >>> Demo = viewlet.SimpleViewletClass(template, bases=(MyViewlet,)) >>> MyViewlet in Demo.__bases__ True >>> Demo(content, request, view, manager).myAttribute 8 The final important feature is the ability to pass in further attributes to the class: >>> Demo = viewlet.SimpleViewletClass( ... template, attributes={'here': 'now', 'lucky': 3}) >>> demo = Demo(content, request, view, manager) >>> demo.here 'now' >>> demo.lucky 3 As for all views, they must provide a name that can also be passed to the function: >>> Demo = viewlet.SimpleViewletClass(template, name='demoViewlet') >>> demo = Demo(content, request, view, manager) >>> demo.__name__ 'demoViewlet' In addition to the the generic viewlet code above, the package comes with two viewlet base classes and helper functions for inserting CSS and Javascript links into HTML headers, since those two are so very common. I am only going to demonstrate the helper functions here, since those demonstrations will fully demonstrate the functionality of the base classes as well. The viewlet will look up the resource it was given and tries to produce the absolute URL for it: >>> class JSResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/resource.js' >>> zope.component.provideAdapter( ... JSResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='resource.js') >>> JSViewlet = viewlet.JavaScriptViewlet('resource.js') >>> print JSViewlet(content, request, view, manager).render().strip() There is also a javascript viewlet base class which knows how to render more then one javascript resource file: >>> class JSSecondResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/second-resource.js' >>> zope.component.provideAdapter( ... JSSecondResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='second-resource.js') >>> JSBundleViewlet = viewlet.JavaScriptBundleViewlet(('resource.js', ... 'second-resource.js')) >>> print JSBundleViewlet(content, request, view, manager).render().strip() The same works for the CSS resource viewlet: >>> class CSSResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/resource.css' >>> zope.component.provideAdapter( ... CSSResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='resource.css') >>> CSSViewlet = viewlet.CSSViewlet('resource.css') >>> print CSSViewlet(content, request, view, manager).render().strip() You can also change the media type and the rel attribute: >>> CSSViewlet = viewlet.CSSViewlet('resource.css', media='print', rel='css') >>> print CSSViewlet(content, request, view, manager).render().strip() There is also a bundle viewlet for CSS links: >>> class CSSPrintResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/print-resource.css' >>> zope.component.provideAdapter( ... CSSPrintResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='print-resource.css') >>> items = [] >>> items.append({'path':'resource.css', 'rel':'stylesheet', 'media':'all'}) >>> items.append({'path':'print-resource.css', 'media':'print'}) >>> CSSBundleViewlet = viewlet.CSSBundleViewlet(items) >>> print CSSBundleViewlet(content, request, view, manager).render().strip() A Complex Example ----------------- The Data ~~~~~~~~ So far we have only demonstrated simple (maybe overly trivial) use cases of the viewlet system. In the following example, we are going to develop a generic contents view for files. The step is to create a file component: >>> class IFile(zope.interface.Interface): ... data = zope.interface.Attribute('Data of file.') >>> class File(object): ... zope.interface.implements(IFile) ... def __init__(self, data=''): ... self.__name__ = '' ... self.data = data Since we want to also provide the size of a file, here a simple implementation of the ``ISized`` interface: >>> from zope import size >>> class FileSized(object): ... zope.interface.implements(size.interfaces.ISized) ... zope.component.adapts(IFile) ... ... def __init__(self, file): ... self.file = file ... ... def sizeForSorting(self): ... return 'byte', len(self.file.data) ... ... def sizeForDisplay(self): ... return '%i bytes' %len(self.file.data) >>> zope.component.provideAdapter(FileSized) We also need a container to which we can add files: >>> class Container(dict): ... def __setitem__(self, name, value): ... value.__name__ = name ... super(Container, self).__setitem__(name, value) Here is some sample data: >>> container = Container() >>> container['test.txt'] = File('Hello World!') >>> container['mypage.html'] = File('Hello World!') >>> container['data.xml'] = File('Hello World!') The View ~~~~~~~~ The contents view of the container should iterate through the container and represent the files in a table: >>> contentsTemplate = os.path.join(temp_dir, 'contents.pt') >>> open(contentsTemplate, 'w').write(''' ... ... ...

Contents

...
... ... ... ''') >>> from zope.browserpage.simpleviewclass import SimpleViewClass >>> Contents = SimpleViewClass(contentsTemplate, name='contents.html') The Viewlet Manager ~~~~~~~~~~~~~~~~~~~ Now we have to write our own viewlet manager. In this case we cannot use the default implementation, since the viewlets will be looked up for each different item: >>> shownColumns = [] >>> class ContentsViewletManager(object): ... zope.interface.implements(interfaces.IViewletManager) ... index = None ... ... def __init__(self, context, request, view): ... self.context = context ... self.request = request ... self.__parent__ = view ... ... def update(self): ... rows = [] ... for name, value in self.context.items(): ... rows.append( ... [zope.component.getMultiAdapter( ... (value, self.request, self.__parent__, self), ... interfaces.IViewlet, name=colname) ... for colname in shownColumns]) ... [entry.update() for entry in rows[-1]] ... self.rows = rows ... ... def render(self, *args, **kw): ... return self.index(*args, **kw) Now we need a template to produce the contents table: >>> tableTemplate = os.path.join(temp_dir, 'table.pt') >>> open(tableTemplate, 'w').write(''' ... ... ... ... ...
... ...
... ''') From the two pieces above, we can generate the final viewlet manager class and register it (it's a bit tedious, I know): >>> from zope.browserpage import ViewPageTemplateFile >>> ContentsViewletManager = type( ... 'ContentsViewletManager', (ContentsViewletManager,), ... {'index': ViewPageTemplateFile(tableTemplate)}) >>> zope.component.provideAdapter( ... ContentsViewletManager, ... (Container, IDefaultBrowserLayer, zope.interface.Interface), ... interfaces.IViewletManager, name='contents') Since we have not defined any viewlets yet, the table is totally empty: >>> contents = Contents(container, request) >>> print contents().strip()

Contents

The Viewlets and the Final Result ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Now let's create a first viewlet for the manager... >>> class NameViewlet(object): ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... self.context = context ... ... def update(self): ... pass ... ... def render(self): ... return self.context.__name__ and register it: >>> zope.component.provideAdapter( ... NameViewlet, ... (IFile, IDefaultBrowserLayer, ... zope.interface.Interface, interfaces.IViewletManager), ... interfaces.IViewlet, name='name') Note how you register the viewlet on ``IFile`` and not on the container. Now we should be able to see the name for each file in the container: >>> print contents().strip()

Contents

Waaa, nothing there! What happened? Well, we have to tell our user preferences that we want to see the name as a column in the table: >>> shownColumns = ['name'] >>> print contents().strip()

Contents

mypage.html
data.xml
test.txt
Let's now write a second viewlet that will display the size of the object for us: >>> class SizeViewlet(object): ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... self.context = context ... ... def update(self): ... pass ... ... def render(self): ... return size.interfaces.ISized(self.context).sizeForDisplay() >>> zope.component.provideAdapter( ... SizeViewlet, ... (IFile, IDefaultBrowserLayer, ... zope.interface.Interface, interfaces.IViewletManager), ... interfaces.IViewlet, name='size') After we added it to the list of shown columns, >>> shownColumns = ['name', 'size'] we can see an entry for it: >>> print contents().strip()

Contents

mypage.html 38 bytes
data.xml 31 bytes
test.txt 12 bytes
If we switch the two columns around, >>> shownColumns = ['size', 'name'] the result will be >>> print contents().strip()

Contents

38 bytes mypage.html
31 bytes data.xml
12 bytes test.txt
Supporting Sorting ~~~~~~~~~~~~~~~~~~ Oftentimes you also want to batch and sort the entries in a table. Since those two features are not part of the view logic, they should be treated with independent components. In this example, we are going to only implement sorting using a simple utility: >>> class ISorter(zope.interface.Interface): ... ... def sort(values): ... """Sort the values.""" >>> class SortByName(object): ... zope.interface.implements(ISorter) ... ... def sort(self, values): ... return sorted(values, lambda x, y: cmp(x.__name__, y.__name__)) >>> zope.component.provideUtility(SortByName(), name='name') >>> class SortBySize(object): ... zope.interface.implements(ISorter) ... ... def sort(self, values): ... return sorted( ... values, ... lambda x, y: cmp(size.interfaces.ISized(x).sizeForSorting(), ... size.interfaces.ISized(y).sizeForSorting())) >>> zope.component.provideUtility(SortBySize(), name='size') Note that we decided to give the sorter utilities the same name as the corresponding viewlet. This convention will make our implementation of the viewlet manager much simpler: >>> sortByColumn = '' >>> class SortedContentsViewletManager(object): ... zope.interface.implements(interfaces.IViewletManager) ... index = None ... ... def __init__(self, context, request, view): ... self.context = context ... self.request = request ... self.__parent__ = view ... ... def update(self): ... values = self.context.values() ... ... if sortByColumn: ... sorter = zope.component.queryUtility(ISorter, sortByColumn) ... if sorter: ... values = sorter.sort(values) ... ... rows = [] ... for value in values: ... rows.append( ... [zope.component.getMultiAdapter( ... (value, self.request, self.__parent__, self), ... interfaces.IViewlet, name=colname) ... for colname in shownColumns]) ... [entry.update() for entry in rows[-1]] ... self.rows = rows ... ... def render(self, *args, **kw): ... return self.index(*args, **kw) As you can see, the concern of sorting is cleanly separated from generating the view code. In MVC terms that means that the controller (sort) is logically separated from the view (viewlets). Let's now do the registration dance for the new viewlet manager. We simply override the existing registration: >>> SortedContentsViewletManager = type( ... 'SortedContentsViewletManager', (SortedContentsViewletManager,), ... {'index': ViewPageTemplateFile(tableTemplate)}) >>> zope.component.provideAdapter( ... SortedContentsViewletManager, ... (Container, IDefaultBrowserLayer, zope.interface.Interface), ... interfaces.IViewletManager, name='contents') Finally we sort the contents by name: >>> shownColumns = ['name', 'size'] >>> sortByColumn = 'name' >>> print contents().strip()

Contents

data.xml 31 bytes
mypage.html 38 bytes
test.txt 12 bytes
Now let's sort by size: >>> sortByColumn = 'size' >>> print contents().strip()

Contents

test.txt 12 bytes
data.xml 31 bytes
mypage.html 38 bytes
That's it! As you can see, in a few steps we have built a pretty flexible contents view with selectable columns and sorting. However, there is a lot of room for extending this example: - Table Header: The table header cell for each column should be a different type of viewlet, but registered under the same name. The column header viewlet also adapts the container not the item. The header column should also be able to control the sorting. - Batching: A simple implementation of batching should work very similar to the sorting feature. Of course, efficient implementations should somehow combine batching and sorting more effectively. - Sorting in ascending and descending order: Currently, you can only sort from the smallest to the highest value; however, this limitation is almost superficial and can easily be removed by making the sorters a bit more flexible. - Further Columns: For a real application, you would want to implement other columns, of course. You would also probably want some sort of fallback for the case that a viewlet is not found for a particular container item and column. Cleanup ------- >>> import shutil >>> shutil.rmtree(temp_dir) ================================ The ``viewletManager`` Directive ================================ The ``viewletManager`` directive allows you to quickly register a new viewlet manager without worrying about the details of the ``adapter`` directive. Before we can use the directives, we have to register their handlers by executing the package's meta configuration: >>> from zope.configuration import xmlconfig >>> context = xmlconfig.string(''' ... ... ... ... ''') Now we can register a viewlet manager: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Let's make sure the directive has really issued a sensible adapter registration; to do that, we create some dummy content, request and view objects: >>> import zope.interface >>> class Content(object): ... zope.interface.implements(zope.interface.Interface) >>> content = Content() >>> from zope.publisher.browser import TestRequest >>> request = TestRequest() >>> from zope.publisher.browser import BrowserView >>> view = BrowserView(content, request) Now let's lookup the manager. This particular registration is pretty boring: >>> import zope.component >>> from zope.viewlet import interfaces >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ... interfaces.IViewletManager, name='defaultmanager') >>> manager object ...> >>> interfaces.IViewletManager.providedBy(manager) True >>> manager.template is None True >>> manager.update() >>> manager.render() u'' However, this registration is not very useful, since we did specify a specific viewlet manager interface, a specific content interface, specific view or specific layer. This means that all viewlets registered will be found. The first step to effectively using the viewlet manager directive is to define a special viewlet manager interface: >>> class ILeftColumn(interfaces.IViewletManager): ... """Left column of my page.""" Now we can register register a manager providing this interface: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> ILeftColumn.providedBy(manager) True >>> manager.template is None True >>> manager.update() >>> manager.render() u'' Next let's see what happens, if we specify a template for the viewlet manager: >>> import os, tempfile >>> temp_dir = tempfile.mkdtemp() >>> leftColumnTemplate = os.path.join(temp_dir, 'leftcolumn.pt') >>> open(leftColumnTemplate, 'w').write(''' ...
...
...
... ''') >>> context = xmlconfig.string(''' ... ... ... ... ''' %leftColumnTemplate, context=context) >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> ILeftColumn.providedBy(manager) True >>> manager.template ...>> >>> manager.update() >>> print manager.render().strip()
Additionally you can specify a class that will serve as a base to the default viewlet manager or be a viewlet manager in its own right. In our case we will provide a custom implementation of the ``sort()`` method, which will sort by a weight attribute in the viewlet: >>> class WeightBasedSorting(object): ... def sort(self, viewlets): ... return sorted(viewlets, ... lambda x, y: cmp(x[1].weight, y[1].weight)) >>> context = xmlconfig.string(''' ... ... ... ... ''' %leftColumnTemplate, context=context) >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> manager.__class__.__bases__ (, ) >>> ILeftColumn.providedBy(manager) True >>> manager.template ...>> >>> manager.update() >>> print manager.render().strip()
Finally, if a non-existent template is specified, an error is raised: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 3.2-7.8 ConfigurationError: ('No such file', '...foo.pt') ========================= The ``viewlet`` Directive ========================= Now that we have a viewlet manager, we have to register some viewlets for it. The ``viewlet`` directive is similar to the ``viewletManager`` directive, except that the viewlet is also registered for a particular manager interface, as seen below: >>> weatherTemplate = os.path.join(temp_dir, 'weather.pt') >>> open(weatherTemplate, 'w').write(''' ...
sunny
... ''') >>> context = xmlconfig.string(''' ... ... ... ... ''' % weatherTemplate, context=context) If we look into the adapter registry, we will find the viewlet: >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='weather') >>> viewlet.render().strip() u'
sunny
' >>> viewlet.extra_string_attributes u'can be specified' The manager now also gives us the output of the one and only viewlet: >>> manager.update() >>> print manager.render().strip()
sunny
Let's now ensure that we can also specify a viewlet class: >>> class Weather(object): ... weight = 0 >>> context = xmlconfig.string(''' ... ... ... ... ''' % weatherTemplate, context=context) >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='weather2') >>> viewlet().strip() u'
sunny
' Okay, so the template-driven cases work. But just specifying a class should also work: >>> class Sport(object): ... weight = 0 ... def __call__(self): ... return u'Red Sox vs. White Sox' >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, name='sport') >>> viewlet() u'Red Sox vs. White Sox' It should also be possible to specify an alternative attribute of the class to be rendered upon calling the viewlet: >>> class Stock(object): ... weight = 0 ... def getStockTicker(self): ... return u'SRC $5.19' >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='stock') >>> viewlet.render() u'SRC $5.19' A final feature the ``viewlet`` directive is that it supports the specification of any number of keyword arguments: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='stock2') >>> viewlet.weight u'8' Error Scenarios --------------- Neither the class or template have been specified: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 3.2-7.8 ConfigurationError: Must specify a class or template The specified attribute is not ``__call__``, but also a template has been specified: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 3.2-9.8 ConfigurationError: Attribute and template cannot be used together. Now, we are not specifying a template, but a class that does not have the specified attribute: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 3.2-9.8 ConfigurationError: The provided class doesn't have the specified attribute Cleanup ------- >>> import shutil >>> shutil.rmtree(temp_dir) ======= CHANGES ======= 3.7.2 (2010-05-25) ------------------ - Fixed unit tests broken under Python 2.4 by the switch to the standard library ``doctest`` module. 3.7.1 (2010-04-30) ------------------ - Removed use of 'zope.testing.doctest' in favor of stdlib's 'doctest. - Fixed dubious quoting in metadirectives.py.

One example would be a viewlet that contains a search form created by a library such as z3c.form, plus a second viewlet that provides a list of search results. This is very simple to accomplish with zope.viewlet but has turned out not to be obvious, so here is an explicit example. It is not written as a doc test since it uses z3c.form which should not become a dependency of zope.viewlet. The viewlets ============ For the purpose of this example, we simulate a search form. Our search results are simply the characters of the search term and are stored on the viewlet as an attribute: class ISearchForm(zope.interface.Interface): searchterm = zope.schema.TextLine(title=u"Search term") class SearchForm(z3c.form.form.Form): ignoreContext = True fields = z3c.form.field.Fields(ISearchForm) results = "" @z3c.form.button.buttonAndHandler(u"Search") def search(self, action): data, errors = self.extractData() self.results = list(data["searchterm"]) (Notice that this example is minimized to point out communication between viewlets, and no care is taken to handle the form itself in the best way possible. In particular, one will probably want to make sure that the actual search is not performed more than once, which may happen with the above code.) The result list viewlet needs to display the results stored on the search form. Therefore, the result list viewlet needs to access that viewlet, which is probably the only tricky part (if there is any at all) in this example: Since viewlets know their viewlet manager which lets viewlets be looked up by ID, it is all a matter of the result list viewlet knowing the ID of the search form. We'll store the search form viewlet's ID as an attribute of the result list viewlet. Let's hard-code the ID for a start, then the result list looks like this: class ResultList(zope.viewlet.viewlet.ViewletBase): searchform_id = "searchform" def update(self): super(ResultList, self).update() searchform = self.manager[self.searchform_id] searchform.update() self.results = searchform.results def render(self): return "
    %s
" % "\n".join(u"
  • %s
    • " % x for x in self.results) Registering the viewlets ======================== As long as we treat the ID of the search form as hard-coded, we have to use the correct name when registering the two viewlets: Making the ID of the search form more flexible now doesn't even require changing any code: the viewlet directive may be passed arbitrary attributes which will be available as attributes of the ResultList objects. The attribute that holds our search form's ID is searchform_id, so we might register the viewlets like this: zope2.13-2.13.21/source/zope.viewlet/src/zope/viewlet/directives.txt0000644000175000017500000003065412214017662024230 0ustar arnauarnau================================ The ``viewletManager`` Directive ================================ The ``viewletManager`` directive allows you to quickly register a new viewlet manager without worrying about the details of the ``adapter`` directive. Before we can use the directives, we have to register their handlers by executing the package's meta configuration: >>> from zope.configuration import xmlconfig >>> context = xmlconfig.string(''' ... ... ... ... ''') Now we can register a viewlet manager: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Let's make sure the directive has really issued a sensible adapter registration; to do that, we create some dummy content, request and view objects: >>> import zope.interface >>> class Content(object): ... zope.interface.implements(zope.interface.Interface) >>> content = Content() >>> from zope.publisher.browser import TestRequest >>> request = TestRequest() >>> from zope.publisher.browser import BrowserView >>> view = BrowserView(content, request) Now let's lookup the manager. This particular registration is pretty boring: >>> import zope.component >>> from zope.viewlet import interfaces >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ... interfaces.IViewletManager, name='defaultmanager') >>> manager object ...> >>> interfaces.IViewletManager.providedBy(manager) True >>> manager.template is None True >>> manager.update() >>> manager.render() u'' However, this registration is not very useful, since we did specify a specific viewlet manager interface, a specific content interface, specific view or specific layer. This means that all viewlets registered will be found. The first step to effectively using the viewlet manager directive is to define a special viewlet manager interface: >>> class ILeftColumn(interfaces.IViewletManager): ... """Left column of my page.""" Now we can register register a manager providing this interface: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> ILeftColumn.providedBy(manager) True >>> manager.template is None True >>> manager.update() >>> manager.render() u'' Next let's see what happens, if we specify a template for the viewlet manager: >>> import os, tempfile >>> temp_dir = tempfile.mkdtemp() >>> leftColumnTemplate = os.path.join(temp_dir, 'leftcolumn.pt') >>> open(leftColumnTemplate, 'w').write(''' ...
    ...
    ...
    ... ''') >>> context = xmlconfig.string(''' ... ... ... ... ''' %leftColumnTemplate, context=context) >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> ILeftColumn.providedBy(manager) True >>> manager.template ...>> >>> manager.update() >>> print manager.render().strip()
    Additionally you can specify a class that will serve as a base to the default viewlet manager or be a viewlet manager in its own right. In our case we will provide a custom implementation of the ``sort()`` method, which will sort by a weight attribute in the viewlet: >>> class WeightBasedSorting(object): ... def sort(self, viewlets): ... return sorted(viewlets, ... lambda x, y: cmp(x[1].weight, y[1].weight)) >>> context = xmlconfig.string(''' ... ... ... ... ''' %leftColumnTemplate, context=context) >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> manager.__class__.__bases__ (, ) >>> ILeftColumn.providedBy(manager) True >>> manager.template ...>> >>> manager.update() >>> print manager.render().strip()
    Finally, if a non-existent template is specified, an error is raised: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 3.2-7.8 ConfigurationError: ('No such file', '...foo.pt') ========================= The ``viewlet`` Directive ========================= Now that we have a viewlet manager, we have to register some viewlets for it. The ``viewlet`` directive is similar to the ``viewletManager`` directive, except that the viewlet is also registered for a particular manager interface, as seen below: >>> weatherTemplate = os.path.join(temp_dir, 'weather.pt') >>> open(weatherTemplate, 'w').write(''' ...
    sunny
    ... ''') >>> context = xmlconfig.string(''' ... ... ... ... ''' % weatherTemplate, context=context) If we look into the adapter registry, we will find the viewlet: >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='weather') >>> viewlet.render().strip() u'
    sunny
    ' >>> viewlet.extra_string_attributes u'can be specified' The manager now also gives us the output of the one and only viewlet: >>> manager.update() >>> print manager.render().strip()
    sunny
    Let's now ensure that we can also specify a viewlet class: >>> class Weather(object): ... weight = 0 >>> context = xmlconfig.string(''' ... ... ... ... ''' % weatherTemplate, context=context) >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='weather2') >>> viewlet().strip() u'
    sunny
    ' Okay, so the template-driven cases work. But just specifying a class should also work: >>> class Sport(object): ... weight = 0 ... def __call__(self): ... return u'Red Sox vs. White Sox' >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, name='sport') >>> viewlet() u'Red Sox vs. White Sox' It should also be possible to specify an alternative attribute of the class to be rendered upon calling the viewlet: >>> class Stock(object): ... weight = 0 ... def getStockTicker(self): ... return u'SRC $5.19' >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='stock') >>> viewlet.render() u'SRC $5.19' A final feature the ``viewlet`` directive is that it supports the specification of any number of keyword arguments: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='stock2') >>> viewlet.weight u'8' Error Scenarios --------------- Neither the class or template have been specified: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Traceback (most recent call last): ...

Using content providers allows us to insert one piece of HTML content. In most Web development, however, you are often interested in defining some sort of region and then allow developers to register content for those regions. >>> from zope.viewlet import interfaces Design Notes ------------ As mentioned above, besides inserting snippets of HTML at places, we more frequently want to define a region in our page and allow specialized content providers to be inserted based on configuration. Those specialized content providers are known as viewlets and are only available inside viewlet managers, which are just a more complex example of content providers. Unfortunately, the Java world does not implement this layer separately. The viewlet manager is most similar to a Java "channel", but we decided against using this name, since it is very generic and not very meaningful. The viewlet has no Java counterpart, since Java does not implement content providers using a component architecture and thus does not register content providers specifically for viewlet managers, which I believe makes the Java implementation less useful as a generic concept. In fact, the main design goal in the Java world is the implementation of reusable and sharable portlets. The scope for Zope 3 is larger, since we want to provide a generic framework for building pluggable user interfaces. The Viewlet Manager ------------------- In this implementation of viewlets, those regions are just content providers called viewlet managers that manage a special type of content providers known as viewlets. Every viewlet manager handles the viewlets registered for it: >>> class ILeftColumn(interfaces.IViewletManager): ... """Viewlet manager located in the left column.""" You can then create a viewlet manager using this interface now: >>> from zope.viewlet import manager >>> LeftColumn = manager.ViewletManager('left', ILeftColumn) Now we have to instantiate it: >>> import zope.interface >>> class Content(object): ... zope.interface.implements(zope.interface.Interface) >>> content = Content() >>> from zope.publisher.browser import TestRequest >>> request = TestRequest() >>> from zope.publisher.interfaces.browser import IBrowserView >>> class View(object): ... zope.interface.implements(IBrowserView) ... def __init__(self, context, request): ... pass >>> view = View(content, request) >>> leftColumn = LeftColumn(content, request, view) So initially nothing gets rendered: >>> leftColumn.update() >>> leftColumn.render() u'' But now we register some viewlets for the manager >>> import zope.component >>> from zope.publisher.interfaces.browser import IDefaultBrowserLayer >>> class WeatherBox(object): ... zope.interface.implements(interfaces.IViewlet) ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... ... def update(self): ... pass ... ... def render(self): ... return u'
    It is sunny today!
    ' >>> # Create a security checker for viewlets. >>> from zope.security.checker import NamesChecker, defineChecker >>> viewletChecker = NamesChecker(('update', 'render')) >>> defineChecker(WeatherBox, viewletChecker) >>> zope.component.provideAdapter( ... WeatherBox, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, ILeftColumn), ... interfaces.IViewlet, name='weather') >>> from zope.location.interfaces import ILocation >>> class SportBox(object): ... zope.interface.implements(interfaces.IViewlet, ... ILocation) ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... ... def update(self): ... pass ... ... def render(self): ... return u'
    Patriots (23) : Steelers (7)
    ' >>> defineChecker(SportBox, viewletChecker) >>> zope.component.provideAdapter( ... SportBox, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, ILeftColumn), ... interfaces.IViewlet, name='sport') and thus the left column is filled. Note that also events get fired before viewlets are updated. We register a simple handler to demonstrate this behaviour. >>> from zope.contentprovider.interfaces import IBeforeUpdateEvent >>> events = [] >>> def handler(ev): ... events.append(ev) >>> zope.component.provideHandler(handler, (IBeforeUpdateEvent,)) >>> leftColumn.update() >>> [(ev, ev.object.__class__.__name__) for ev in events] [(, 'SportBox'), (, 'WeatherBox')] >>> print leftColumn.render()
    Patriots (23) : Steelers (7)
    It is sunny today!
    But this is of course pretty lame, since there is no way of specifying how the viewlets are put together. But we have a solution. The second argument of the ``ViewletManager()`` function is a template in which we can specify how the viewlets are put together: >>> import os, tempfile >>> temp_dir = tempfile.mkdtemp() >>> leftColTemplate = os.path.join(temp_dir, 'leftCol.pt') >>> open(leftColTemplate, 'w').write(''' ...
    ... ...
    ... ''') >>> LeftColumn = manager.ViewletManager('left', ILeftColumn, ... template=leftColTemplate) >>> leftColumn = LeftColumn(content, request, view) TODO: Fix this silly thing; viewlets should be directly available. As you can see, the viewlet manager provides a global ``options/viewlets`` variable that is an iterable of all the available viewlets in the correct order: >>> leftColumn.update() >>> print leftColumn.render().strip()
    Patriots (23) : Steelers (7)
    It is sunny today!
    If a viewlet provides ILocation the ``__name__`` attribute of the viewlet is set to the name under which the viewlet is registered. >>> [getattr(viewlet, '__name__', None) for viewlet in leftColumn.viewlets] [u'sport', None] You can also lookup the viewlets directly for management purposes: >>> leftColumn['weather'] >>> leftColumn.get('weather') The viewlet manager also provides the __contains__ method defined in IReadMapping: >>> 'weather' in leftColumn True >>> 'unknown' in leftColumn False If the viewlet is not found, then the expected behavior is provided: >>> leftColumn['stock'] Traceback (most recent call last): ... ComponentLookupError: No provider with name `stock` found. >>> leftColumn.get('stock') is None True Customizing the default Viewlet Manager --------------------------------------- One important feature of any viewlet manager is to be able to filter and sort the viewlets it is displaying. The default viewlet manager that we have been using in the tests above, supports filtering by access availability and sorting via the viewlet's ``__cmp__()`` method (default). You can easily override this default policy by providing a base viewlet manager class. In our case we will manage the viewlets using a global list: >>> shown = ['weather', 'sport'] The viewlet manager base class now uses this list: >>> class ListViewletManager(object): ... ... def filter(self, viewlets): ... viewlets = super(ListViewletManager, self).filter(viewlets) ... return [(name, viewlet) ... for name, viewlet in viewlets ... if name in shown] ... ... def sort(self, viewlets): ... viewlets = dict(viewlets) ... return [(name, viewlets[name]) for name in shown] Let's now create a new viewlet manager: >>> LeftColumn = manager.ViewletManager( ... 'left', ILeftColumn, bases=(ListViewletManager,), ... template=leftColTemplate) >>> leftColumn = LeftColumn(content, request, view) So we get the weather box first and the sport box second: >>> leftColumn.update() >>> print leftColumn.render().strip()
    It is sunny today!
    Patriots (23) : Steelers (7)
    Now let's change the order... >>> shown.reverse() and the order should switch as well: >>> leftColumn.update() >>> print leftColumn.render().strip()
    Patriots (23) : Steelers (7)
    It is sunny today!
    Of course, we also can remove a shown viewlet: >>> weather = shown.pop() >>> leftColumn.update() >>> print leftColumn.render().strip()
    Patriots (23) : Steelers (7)
    WeightOrderedViewletManager --------------------------- The weight ordered viewlet manager offers ordering viewlets by a additional weight argument. Viewlets which doesn't provide a weight attribute will get a weight of 0 (zero). Let's define a new column: >>> class IWeightedColumn(interfaces.IViewletManager): ... """Column with weighted viewlet manager.""" First register a template for the weight ordered viewlet manager: >>> weightedColTemplate = os.path.join(temp_dir, 'weightedColTemplate.pt') >>> open(weightedColTemplate, 'w').write(''' ...
    ... ...
    ... ''') And create a new weight ordered viewlet manager: >>> from zope.viewlet.manager import WeightOrderedViewletManager >>> WeightedColumn = manager.ViewletManager( ... 'left', IWeightedColumn, bases=(WeightOrderedViewletManager,), ... template=weightedColTemplate) >>> weightedColumn = WeightedColumn(content, request, view) Let's create some viewlets: >>> from zope.viewlet import viewlet >>> class FirstViewlet(viewlet.ViewletBase): ... ... weight = 1 ... ... def render(self): ... return u'
    first
    ' >>> class SecondViewlet(viewlet.ViewletBase): ... ... weight = 2 ... ... def render(self): ... return u'
    second
    ' >>> class ThirdViewlet(viewlet.ViewletBase): ... ... weight = 3 ... ... def render(self): ... return u'
    third
    ' >>> class UnWeightedViewlet(viewlet.ViewletBase): ... ... def render(self): ... return u'
    unweighted
    ' >>> defineChecker(FirstViewlet, viewletChecker) >>> defineChecker(SecondViewlet, viewletChecker) >>> defineChecker(ThirdViewlet, viewletChecker) >>> defineChecker(UnWeightedViewlet, viewletChecker) >>> zope.component.provideAdapter( ... ThirdViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='third') >>> zope.component.provideAdapter( ... FirstViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='first') >>> zope.component.provideAdapter( ... SecondViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='second') >>> zope.component.provideAdapter( ... UnWeightedViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='unweighted') And check the order: >>> weightedColumn.update() >>> print weightedColumn.render().strip()
    unweighted
    first
    second
    third
    ConditionalViewletManager ------------------------- The conditional ordered viewlet manager offers ordering viewlets by a additional weight argument and filters by the available attribute if a supported by the viewlet. Viewlets which doesn't provide a available attribute will not get skipped. The default weight value for viewlets which doesn't provide a weight attribute is 0 (zero). Let's define a new column: >>> class IConditionalColumn(interfaces.IViewletManager): ... """Column with weighted viewlet manager.""" First register a template for the weight ordered viewlet manager: >>> conditionalColTemplate = os.path.join(temp_dir, ... 'conditionalColTemplate.pt') >>> open(conditionalColTemplate, 'w').write(''' ...
    ... ...
    ... ''') And create a new conditional viewlet manager: >>> from zope.viewlet.manager import ConditionalViewletManager >>> ConditionalColumn = manager.ViewletManager( ... 'left', IConditionalColumn, bases=(ConditionalViewletManager,), ... template=conditionalColTemplate) >>> conditionalColumn = ConditionalColumn(content, request, view) Let's create some viewlets. We also use the previous viewlets supporting no weight and or no available attribute: >>> from zope.viewlet import viewlet >>> class AvailableViewlet(viewlet.ViewletBase): ... ... weight = 4 ... ... available = True ... ... def render(self): ... return u'
    available
    ' >>> class UnAvailableViewlet(viewlet.ViewletBase): ... ... weight = 5 ... ... available = False ... ... def render(self): ... return u'
    not available
    ' >>> defineChecker(AvailableViewlet, viewletChecker) >>> defineChecker(UnAvailableViewlet, viewletChecker) >>> zope.component.provideAdapter( ... ThirdViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='third') >>> zope.component.provideAdapter( ... FirstViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='first') >>> zope.component.provideAdapter( ... SecondViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='second') >>> zope.component.provideAdapter( ... UnWeightedViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='unweighted') >>> zope.component.provideAdapter( ... AvailableViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='available') >>> zope.component.provideAdapter( ... UnAvailableViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='unavailable') And check the order: >>> conditionalColumn.update() >>> print conditionalColumn.render().strip()
    unweighted

    available
    Viewlet Base Classes -------------------- To make the creation of viewlets simpler, a set of useful base classes and helper functions are provided. The first class is a base class that simply defines the constructor: >>> base = viewlet.ViewletBase('context', 'request', 'view', 'manager') >>> base.context 'context' >>> base.request 'request' >>> base.__parent__ 'view' >>> base.manager 'manager' But a default ``render()`` method implementation is not provided: >>> base.render() Traceback (most recent call last): ... NotImplementedError: `render` method must be implemented by subclass. If you have already an existing class that produces the HTML content in some method, then the ``SimpleAttributeViewlet`` might be for you, since it can be used to convert any class quickly into a viewlet: >>> class FooViewlet(viewlet.SimpleAttributeViewlet): ... __page_attribute__ = 'foo' ... ... def foo(self): ... return 'output' The `__page_attribute__` attribute provides the name of the function to call for rendering. >>> foo = FooViewlet('context', 'request', 'view', 'manager') >>> foo.foo() 'output' >>> foo.render() 'output' If you specify `render` as the attribute an error is raised to prevent infinite recursion: >>> foo.__page_attribute__ = 'render' >>> foo.render() Traceback (most recent call last): ... AttributeError: render The same is true if the specified attribute does not exist: >>> foo.__page_attribute__ = 'bar' >>> foo.render() Traceback (most recent call last): ... AttributeError: 'FooViewlet' object has no attribute 'bar' To create simple template-based viewlets you can use the ``SimpleViewletClass()`` function. This function is very similar to its view equivalent and is used by the ZCML directives to create viewlets. The result of this function call will be a fully functional viewlet class. Let's start by simply specifying a template only: >>> template = os.path.join(temp_dir, 'demoTemplate.pt') >>> open(template, 'w').write('''
    contents
    ''') >>> Demo = viewlet.SimpleViewletClass(template) >>> print Demo(content, request, view, manager).render()
    contents
    Now let's additionally specify a class that can provide additional features: >>> class MyViewlet(object): ... myAttribute = 8 >>> Demo = viewlet.SimpleViewletClass(template, bases=(MyViewlet,)) >>> MyViewlet in Demo.__bases__ True >>> Demo(content, request, view, manager).myAttribute 8 The final important feature is the ability to pass in further attributes to the class: >>> Demo = viewlet.SimpleViewletClass( ... template, attributes={'here': 'now', 'lucky': 3}) >>> demo = Demo(content, request, view, manager) >>> demo.here 'now' >>> demo.lucky 3 As for all views, they must provide a name that can also be passed to the function: >>> Demo = viewlet.SimpleViewletClass(template, name='demoViewlet') >>> demo = Demo(content, request, view, manager) >>> demo.__name__ 'demoViewlet' In addition to the the generic viewlet code above, the package comes with two viewlet base classes and helper functions for inserting CSS and Javascript links into HTML headers, since those two are so very common. I am only going to demonstrate the helper functions here, since those demonstrations will fully demonstrate the functionality of the base classes as well. The viewlet will look up the resource it was given and tries to produce the absolute URL for it: >>> class JSResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/resource.js' >>> zope.component.provideAdapter( ... JSResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='resource.js') >>> JSViewlet = viewlet.JavaScriptViewlet('resource.js') >>> print JSViewlet(content, request, view, manager).render().strip() There is also a javascript viewlet base class which knows how to render more then one javascript resource file: >>> class JSSecondResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/second-resource.js' >>> zope.component.provideAdapter( ... JSSecondResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='second-resource.js') >>> JSBundleViewlet = viewlet.JavaScriptBundleViewlet(('resource.js', ... 'second-resource.js')) >>> print JSBundleViewlet(content, request, view, manager).render().strip() The same works for the CSS resource viewlet: >>> class CSSResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/resource.css' >>> zope.component.provideAdapter( ... CSSResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='resource.css') >>> CSSViewlet = viewlet.CSSViewlet('resource.css') >>> print CSSViewlet(content, request, view, manager).render().strip() You can also change the media type and the rel attribute: >>> CSSViewlet = viewlet.CSSViewlet('resource.css', media='print', rel='css') >>> print CSSViewlet(content, request, view, manager).render().strip() There is also a bundle viewlet for CSS links: >>> class CSSPrintResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/print-resource.css' >>> zope.component.provideAdapter( ... CSSPrintResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='print-resource.css') >>> items = [] >>> items.append({'path':'resource.css', 'rel':'stylesheet', 'media':'all'}) >>> items.append({'path':'print-resource.css', 'media':'print'}) >>> CSSBundleViewlet = viewlet.CSSBundleViewlet(items) >>> print CSSBundleViewlet(content, request, view, manager).render().strip() A Complex Example ----------------- The Data ~~~~~~~~ So far we have only demonstrated simple (maybe overly trivial) use cases of the viewlet system. In the following example, we are going to develop a generic contents view for files. The step is to create a file component: >>> class IFile(zope.interface.Interface): ... data = zope.interface.Attribute('Data of file.') >>> class File(object): ... zope.interface.implements(IFile) ... def __init__(self, data=''): ... self.__name__ = '' ... self.data = data Since we want to also provide the size of a file, here a simple implementation of the ``ISized`` interface: >>> from zope import size >>> class FileSized(object): ... zope.interface.implements(size.interfaces.ISized) ... zope.component.adapts(IFile) ... ... def __init__(self, file): ... self.file = file ... ... def sizeForSorting(self): ... return 'byte', len(self.file.data) ... ... def sizeForDisplay(self): ... return '%i bytes' %len(self.file.data) >>> zope.component.provideAdapter(FileSized) We also need a container to which we can add files: >>> class Container(dict): ... def __setitem__(self, name, value): ... value.__name__ = name ... super(Container, self).__setitem__(name, value) Here is some sample data: >>> container = Container() >>> container['test.txt'] = File('Hello World!') >>> container['mypage.html'] = File('Hello World!') >>> container['data.xml'] = File('Hello World!') The View ~~~~~~~~ The contents view of the container should iterate through the container and represent the files in a table: >>> contentsTemplate = os.path.join(temp_dir, 'contents.pt') >>> open(contentsTemplate, 'w').write(''' ... ... ...

    Contents

    ...
    ... ... ... ''') >>> from zope.browserpage.simpleviewclass import SimpleViewClass >>> Contents = SimpleViewClass(contentsTemplate, name='contents.html') The Viewlet Manager ~~~~~~~~~~~~~~~~~~~ Now we have to write our own viewlet manager. In this case we cannot use the default implementation, since the viewlets will be looked up for each different item: >>> shownColumns = [] >>> class ContentsViewletManager(object): ... zope.interface.implements(interfaces.IViewletManager) ... index = None ... ... def __init__(self, context, request, view): ... self.context = context ... self.request = request ... self.__parent__ = view ... ... def update(self): ... rows = [] ... for name, value in self.context.items(): ... rows.append( ... [zope.component.getMultiAdapter( ... (value, self.request, self.__parent__, self), ... interfaces.IViewlet, name=colname) ... for colname in shownColumns]) ... [entry.update() for entry in rows[-1]] ... self.rows = rows ... ... def render(self, *args, **kw): ... return self.index(*args, **kw) Now we need a template to produce the contents table: >>> tableTemplate = os.path.join(temp_dir, 'table.pt') >>> open(tableTemplate, 'w').write(''' ... ... ... ... ...
    ... ...
    ... ''') From the two pieces above, we can generate the final viewlet manager class and register it (it's a bit tedious, I know): >>> from zope.browserpage import ViewPageTemplateFile >>> ContentsViewletManager = type( ... 'ContentsViewletManager', (ContentsViewletManager,), ... {'index': ViewPageTemplateFile(tableTemplate)}) >>> zope.component.provideAdapter( ... ContentsViewletManager, ... (Container, IDefaultBrowserLayer, zope.interface.Interface), ... interfaces.IViewletManager, name='contents') Since we have not defined any viewlets yet, the table is totally empty: >>> contents = Contents(container, request) >>> print contents().strip()

    Contents

    The Viewlets and the Final Result ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Now let's create a first viewlet for the manager... >>> class NameViewlet(object): ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... self.context = context ... ... def update(self): ... pass ... ... def render(self): ... return self.context.__name__ and register it: >>> zope.component.provideAdapter( ... NameViewlet, ... (IFile, IDefaultBrowserLayer, ... zope.interface.Interface, interfaces.IViewletManager), ... interfaces.IViewlet, name='name') Note how you register the viewlet on ``IFile`` and not on the container. Now we should be able to see the name for each file in the container: >>> print contents().strip()

    Contents

    Waaa, nothing there! What happened? Well, we have to tell our user preferences that we want to see the name as a column in the table: >>> shownColumns = ['name'] >>> print contents().strip()

    Contents

    mypage.html
    data.xml
    test.txt
    Let's now write a second viewlet that will display the size of the object for us: >>> class SizeViewlet(object): ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... self.context = context ... ... def update(self): ... pass ... ... def render(self): ... return size.interfaces.ISized(self.context).sizeForDisplay() >>> zope.component.provideAdapter( ... SizeViewlet, ... (IFile, IDefaultBrowserLayer, ... zope.interface.Interface, interfaces.IViewletManager), ... interfaces.IViewlet, name='size') After we added it to the list of shown columns, >>> shownColumns = ['name', 'size'] we can see an entry for it: >>> print contents().strip()

    Contents

    mypage.html 38 bytes
    data.xml 31 bytes
    test.txt 12 bytes
    If we switch the two columns around, >>> shownColumns = ['size', 'name'] the result will be >>> print contents().strip()

    Supporting Sorting ~~~~~~~~~~~~~~~~~~ Oftentimes you also want to batch and sort the entries in a table. Since those two features are not part of the view logic, they should be treated with independent components. In this example, we are going to only implement sorting using a simple utility: >>> class ISorter(zope.interface.Interface): ... ... def sort(values): ... """Sort the values.""" >>> class SortByName(object): ... zope.interface.implements(ISorter) ... ... def sort(self, values): ... return sorted(values, lambda x, y: cmp(x.__name__, y.__name__)) >>> zope.component.provideUtility(SortByName(), name='name') >>> class SortBySize(object): ... zope.interface.implements(ISorter) ... ... def sort(self, values): ... return sorted( ... values, ... lambda x, y: cmp(size.interfaces.ISized(x).sizeForSorting(), ... size.interfaces.ISized(y).sizeForSorting())) >>> zope.component.provideUtility(SortBySize(), name='size') Note that we decided to give the sorter utilities the same name as the corresponding viewlet. This convention will make our implementation of the viewlet manager much simpler: >>> sortByColumn = '' >>> class SortedContentsViewletManager(object): ... zope.interface.implements(interfaces.IViewletManager) ... index = None ... ... def __init__(self, context, request, view): ... self.context = context ... self.request = request ... self.__parent__ = view ... ... def update(self): ... values = self.context.values() ... ... if sortByColumn: ... sorter = zope.component.queryUtility(ISorter, sortByColumn) ... if sorter: ... values = sorter.sort(values) ... ... rows = [] ... for value in values: ... rows.append( ... [zope.component.getMultiAdapter( ... (value, self.request, self.__parent__, self), ... interfaces.IViewlet, name=colname) ... for colname in shownColumns]) ... [entry.update() for entry in rows[-1]] ... self.rows = rows ... ... def render(self, *args, **kw): ... return self.index(*args, **kw) As you can see, the concern of sorting is cleanly separated from generating the view code. In MVC terms that means that the controller (sort) is logically separated from the view (viewlets). Let's now do the registration dance for the new viewlet manager. We simply override the existing registration: >>> SortedContentsViewletManager = type( ... 'SortedContentsViewletManager', (SortedContentsViewletManager,), ... {'index': ViewPageTemplateFile(tableTemplate)}) >>> zope.component.provideAdapter( ... SortedContentsViewletManager, ... (Container, IDefaultBrowserLayer, zope.interface.Interface), ... interfaces.IViewletManager, name='contents') Finally we sort the contents by name: >>> shownColumns = ['name', 'size'] >>> sortByColumn = 'name' >>> print contents().strip()

    Contents

    data.xml 31 bytes
    mypage.html 38 bytes
    test.txt 12 bytes
    Now let's sort by size: >>> sortByColumn = 'size' >>> print contents().strip()

    That's it! As you can see, in a few steps we have built a pretty flexible contents view with selectable columns and sorting. However, there is a lot of room for extending this example: - Table Header: The table header cell for each column should be a different type of viewlet, but registered under the same name. The column header viewlet also adapts the container not the item. The header column should also be able to control the sorting. - Batching: A simple implementation of batching should work very similar to the sorting feature. Of course, efficient implementations should somehow combine batching and sorting more effectively. - Sorting in ascending and descending order: Currently, you can only sort from the smallest to the highest value; however, this limitation is almost superficial and can easily be removed by making the sorters a bit more flexible. - Further Columns: For a real application, you would want to implement other columns, of course. You would also probably want some sort of fallback for the case that a viewlet is not found for a particular container item and column.

Detailed Documentation ********************** ============================= Viewlets and Viewlet Managers ============================= Let's start with some motivation. Using content providers allows us to insert one piece of HTML content. In most Web development, however, you are often interested in defining some sort of region and then allow developers to register content for those regions. >>> from zope.viewlet import interfaces Design Notes ------------ As mentioned above, besides inserting snippets of HTML at places, we more frequently want to define a region in our page and allow specialized content providers to be inserted based on configuration. Those specialized content providers are known as viewlets and are only available inside viewlet managers, which are just a more complex example of content providers. Unfortunately, the Java world does not implement this layer separately. The viewlet manager is most similar to a Java "channel", but we decided against using this name, since it is very generic and not very meaningful. The viewlet has no Java counterpart, since Java does not implement content providers using a component architecture and thus does not register content providers specifically for viewlet managers, which I believe makes the Java implementation less useful as a generic concept. In fact, the main design goal in the Java world is the implementation of reusable and sharable portlets. The scope for Zope 3 is larger, since we want to provide a generic framework for building pluggable user interfaces. The Viewlet Manager ------------------- In this implementation of viewlets, those regions are just content providers called viewlet managers that manage a special type of content providers known as viewlets. Every viewlet manager handles the viewlets registered for it: >>> class ILeftColumn(interfaces.IViewletManager): ... """Viewlet manager located in the left column.""" You can then create a viewlet manager using this interface now: >>> from zope.viewlet import manager >>> LeftColumn = manager.ViewletManager('left', ILeftColumn) Now we have to instantiate it: >>> import zope.interface >>> class Content(object): ... zope.interface.implements(zope.interface.Interface) >>> content = Content() >>> from zope.publisher.browser import TestRequest >>> request = TestRequest() >>> from zope.publisher.interfaces.browser import IBrowserView >>> class View(object): ... zope.interface.implements(IBrowserView) ... def __init__(self, context, request): ... pass >>> view = View(content, request) >>> leftColumn = LeftColumn(content, request, view) So initially nothing gets rendered: >>> leftColumn.update() >>> leftColumn.render() u'' But now we register some viewlets for the manager >>> import zope.component >>> from zope.publisher.interfaces.browser import IDefaultBrowserLayer >>> class WeatherBox(object): ... zope.interface.implements(interfaces.IViewlet) ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... ... def update(self): ... pass ... ... def render(self): ... return u'

    ' >>> defineChecker(SportBox, viewletChecker) >>> zope.component.provideAdapter( ... SportBox, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, ILeftColumn), ... interfaces.IViewlet, name='sport') and thus the left column is filled. Note that also events get fired before viewlets are updated. We register a simple handler to demonstrate this behaviour. >>> from zope.contentprovider.interfaces import IBeforeUpdateEvent >>> events = [] >>> def handler(ev): ... events.append(ev) >>> zope.component.provideHandler(handler, (IBeforeUpdateEvent,)) >>> leftColumn.update() >>> [(ev, ev.object.__class__.__name__) for ev in events] [(, 'SportBox'), (, 'WeatherBox')] >>> print leftColumn.render()
    Patriots (23) : Steelers (7)
    It is sunny today!
    But this is of course pretty lame, since there is no way of specifying how the viewlets are put together. But we have a solution. The second argument of the ``ViewletManager()`` function is a template in which we can specify how the viewlets are put together: >>> import os, tempfile >>> temp_dir = tempfile.mkdtemp() >>> leftColTemplate = os.path.join(temp_dir, 'leftCol.pt') >>> open(leftColTemplate, 'w').write(''' ...
    ... ...
    ... ''') >>> LeftColumn = manager.ViewletManager('left', ILeftColumn, ... template=leftColTemplate) >>> leftColumn = LeftColumn(content, request, view) TODO: Fix this silly thing; viewlets should be directly available. As you can see, the viewlet manager provides a global ``options/viewlets`` variable that is an iterable of all the available viewlets in the correct order: >>> leftColumn.update() >>> print leftColumn.render().strip()
    Patriots (23) : Steelers (7)
    It is sunny today!
    If a viewlet provides ILocation the ``__name__`` attribute of the viewlet is set to the name under which the viewlet is registered. >>> [getattr(viewlet, '__name__', None) for viewlet in leftColumn.viewlets] [u'sport', None] You can also lookup the viewlets directly for management purposes: >>> leftColumn['weather'] >>> leftColumn.get('weather') The viewlet manager also provides the __contains__ method defined in IReadMapping: >>> 'weather' in leftColumn True >>> 'unknown' in leftColumn False If the viewlet is not found, then the expected behavior is provided: >>> leftColumn['stock'] Traceback (most recent call last): ... ComponentLookupError: No provider with name `stock` found. >>> leftColumn.get('stock') is None True Customizing the default Viewlet Manager --------------------------------------- One important feature of any viewlet manager is to be able to filter and sort the viewlets it is displaying. The default viewlet manager that we have been using in the tests above, supports filtering by access availability and sorting via the viewlet's ``__cmp__()`` method (default). You can easily override this default policy by providing a base viewlet manager class. In our case we will manage the viewlets using a global list: >>> shown = ['weather', 'sport'] The viewlet manager base class now uses this list: >>> class ListViewletManager(object): ... ... def filter(self, viewlets): ... viewlets = super(ListViewletManager, self).filter(viewlets) ... return [(name, viewlet) ... for name, viewlet in viewlets ... if name in shown] ... ... def sort(self, viewlets): ... viewlets = dict(viewlets) ... return [(name, viewlets[name]) for name in shown] Let's now create a new viewlet manager: >>> LeftColumn = manager.ViewletManager( ... 'left', ILeftColumn, bases=(ListViewletManager,), ... template=leftColTemplate) >>> leftColumn = LeftColumn(content, request, view) So we get the weather box first and the sport box second: >>> leftColumn.update() >>> print leftColumn.render().strip()
    It is sunny today!
    Patriots (23) : Steelers (7)
    Now let's change the order... >>> shown.reverse() and the order should switch as well: >>> leftColumn.update() >>> print leftColumn.render().strip()
    Patriots (23) : Steelers (7)
    It is sunny today!
    Of course, we also can remove a shown viewlet: >>> weather = shown.pop() >>> leftColumn.update() >>> print leftColumn.render().strip()
    Patriots (23) : Steelers (7)
    WeightOrderedViewletManager --------------------------- The weight ordered viewlet manager offers ordering viewlets by a additional weight argument. Viewlets which doesn't provide a weight attribute will get a weight of 0 (zero). Let's define a new column: >>> class IWeightedColumn(interfaces.IViewletManager): ... """Column with weighted viewlet manager.""" First register a template for the weight ordered viewlet manager: >>> weightedColTemplate = os.path.join(temp_dir, 'weightedColTemplate.pt') >>> open(weightedColTemplate, 'w').write(''' ...
    ... ...
    ... ''') And create a new weight ordered viewlet manager: >>> from zope.viewlet.manager import WeightOrderedViewletManager >>> WeightedColumn = manager.ViewletManager( ... 'left', IWeightedColumn, bases=(WeightOrderedViewletManager,), ... template=weightedColTemplate) >>> weightedColumn = WeightedColumn(content, request, view) Let's create some viewlets: >>> from zope.viewlet import viewlet >>> class FirstViewlet(viewlet.ViewletBase): ... ... weight = 1 ... ... def render(self): ... return u'
    first
    ' >>> class SecondViewlet(viewlet.ViewletBase): ... ... weight = 2 ... ... def render(self): ... return u'
    second
    ' >>> class ThirdViewlet(viewlet.ViewletBase): ... ... weight = 3 ... ... def render(self): ... return u'
    third
    ' >>> class UnWeightedViewlet(viewlet.ViewletBase): ... ... def render(self): ... return u'
    unweighted
    ' >>> defineChecker(FirstViewlet, viewletChecker) >>> defineChecker(SecondViewlet, viewletChecker) >>> defineChecker(ThirdViewlet, viewletChecker) >>> defineChecker(UnWeightedViewlet, viewletChecker) >>> zope.component.provideAdapter( ... ThirdViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='third') >>> zope.component.provideAdapter( ... FirstViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='first') >>> zope.component.provideAdapter( ... SecondViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='second') >>> zope.component.provideAdapter( ... UnWeightedViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IWeightedColumn), ... interfaces.IViewlet, name='unweighted') And check the order: >>> weightedColumn.update() >>> print weightedColumn.render().strip()
    unweighted
    first
    second
    third
    ConditionalViewletManager ------------------------- The conditional ordered viewlet manager offers ordering viewlets by a additional weight argument and filters by the available attribute if a supported by the viewlet. Viewlets which doesn't provide a available attribute will not get skipped. The default weight value for viewlets which doesn't provide a weight attribute is 0 (zero). Let's define a new column: >>> class IConditionalColumn(interfaces.IViewletManager): ... """Column with weighted viewlet manager.""" First register a template for the weight ordered viewlet manager: >>> conditionalColTemplate = os.path.join(temp_dir, ... 'conditionalColTemplate.pt') >>> open(conditionalColTemplate, 'w').write(''' ...
    ... ...
    ... ''') And create a new conditional viewlet manager: >>> from zope.viewlet.manager import ConditionalViewletManager >>> ConditionalColumn = manager.ViewletManager( ... 'left', IConditionalColumn, bases=(ConditionalViewletManager,), ... template=conditionalColTemplate) >>> conditionalColumn = ConditionalColumn(content, request, view) Let's create some viewlets. We also use the previous viewlets supporting no weight and or no available attribute: >>> from zope.viewlet import viewlet >>> class AvailableViewlet(viewlet.ViewletBase): ... ... weight = 4 ... ... available = True ... ... def render(self): ... return u'
    available
    ' >>> class UnAvailableViewlet(viewlet.ViewletBase): ... ... weight = 5 ... ... available = False ... ... def render(self): ... return u'
    not available
    ' >>> defineChecker(AvailableViewlet, viewletChecker) >>> defineChecker(UnAvailableViewlet, viewletChecker) >>> zope.component.provideAdapter( ... ThirdViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='third') >>> zope.component.provideAdapter( ... FirstViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='first') >>> zope.component.provideAdapter( ... SecondViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='second') >>> zope.component.provideAdapter( ... UnWeightedViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='unweighted') >>> zope.component.provideAdapter( ... AvailableViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='available') >>> zope.component.provideAdapter( ... UnAvailableViewlet, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, IConditionalColumn), ... interfaces.IViewlet, name='unavailable') And check the order: >>> conditionalColumn.update() >>> print conditionalColumn.render().strip()
    unweighted

    Viewlet Base Classes -------------------- To make the creation of viewlets simpler, a set of useful base classes and helper functions are provided. The first class is a base class that simply defines the constructor: >>> base = viewlet.ViewletBase('context', 'request', 'view', 'manager') >>> base.context 'context' >>> base.request 'request' >>> base.__parent__ 'view' >>> base.manager 'manager' But a default ``render()`` method implementation is not provided: >>> base.render() Traceback (most recent call last): ... NotImplementedError: `render` method must be implemented by subclass. If you have already an existing class that produces the HTML content in some method, then the ``SimpleAttributeViewlet`` might be for you, since it can be used to convert any class quickly into a viewlet: >>> class FooViewlet(viewlet.SimpleAttributeViewlet): ... __page_attribute__ = 'foo' ... ... def foo(self): ... return 'output' The `__page_attribute__` attribute provides the name of the function to call for rendering. >>> foo = FooViewlet('context', 'request', 'view', 'manager') >>> foo.foo() 'output' >>> foo.render() 'output' If you specify `render` as the attribute an error is raised to prevent infinite recursion: >>> foo.__page_attribute__ = 'render' >>> foo.render() Traceback (most recent call last): ... AttributeError: render The same is true if the specified attribute does not exist: >>> foo.__page_attribute__ = 'bar' >>> foo.render() Traceback (most recent call last): ... AttributeError: 'FooViewlet' object has no attribute 'bar' To create simple template-based viewlets you can use the ``SimpleViewletClass()`` function. This function is very similar to its view equivalent and is used by the ZCML directives to create viewlets. The result of this function call will be a fully functional viewlet class. Let's start by simply specifying a template only: >>> template = os.path.join(temp_dir, 'demoTemplate.pt') >>> open(template, 'w').write('''
    contents
    ''') >>> Demo = viewlet.SimpleViewletClass(template) >>> print Demo(content, request, view, manager).render()
    contents
    Now let's additionally specify a class that can provide additional features: >>> class MyViewlet(object): ... myAttribute = 8 >>> Demo = viewlet.SimpleViewletClass(template, bases=(MyViewlet,)) >>> MyViewlet in Demo.__bases__ True >>> Demo(content, request, view, manager).myAttribute 8 The final important feature is the ability to pass in further attributes to the class: >>> Demo = viewlet.SimpleViewletClass( ... template, attributes={'here': 'now', 'lucky': 3}) >>> demo = Demo(content, request, view, manager) >>> demo.here 'now' >>> demo.lucky 3 As for all views, they must provide a name that can also be passed to the function: >>> Demo = viewlet.SimpleViewletClass(template, name='demoViewlet') >>> demo = Demo(content, request, view, manager) >>> demo.__name__ 'demoViewlet' In addition to the the generic viewlet code above, the package comes with two viewlet base classes and helper functions for inserting CSS and Javascript links into HTML headers, since those two are so very common. I am only going to demonstrate the helper functions here, since those demonstrations will fully demonstrate the functionality of the base classes as well. The viewlet will look up the resource it was given and tries to produce the absolute URL for it: >>> class JSResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/resource.js' >>> zope.component.provideAdapter( ... JSResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='resource.js') >>> JSViewlet = viewlet.JavaScriptViewlet('resource.js') >>> print JSViewlet(content, request, view, manager).render().strip() There is also a javascript viewlet base class which knows how to render more then one javascript resource file: >>> class JSSecondResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/second-resource.js' >>> zope.component.provideAdapter( ... JSSecondResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='second-resource.js') >>> JSBundleViewlet = viewlet.JavaScriptBundleViewlet(('resource.js', ... 'second-resource.js')) >>> print JSBundleViewlet(content, request, view, manager).render().strip() The same works for the CSS resource viewlet: >>> class CSSResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/resource.css' >>> zope.component.provideAdapter( ... CSSResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='resource.css') >>> CSSViewlet = viewlet.CSSViewlet('resource.css') >>> print CSSViewlet(content, request, view, manager).render().strip() You can also change the media type and the rel attribute: >>> CSSViewlet = viewlet.CSSViewlet('resource.css', media='print', rel='css') >>> print CSSViewlet(content, request, view, manager).render().strip() There is also a bundle viewlet for CSS links: >>> class CSSPrintResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/print-resource.css' >>> zope.component.provideAdapter( ... CSSPrintResource, ... (IDefaultBrowserLayer,), ... zope.interface.Interface, name='print-resource.css') >>> items = [] >>> items.append({'path':'resource.css', 'rel':'stylesheet', 'media':'all'}) >>> items.append({'path':'print-resource.css', 'media':'print'}) >>> CSSBundleViewlet = viewlet.CSSBundleViewlet(items) >>> print CSSBundleViewlet(content, request, view, manager).render().strip() A Complex Example ----------------- The Data ~~~~~~~~ So far we have only demonstrated simple (maybe overly trivial) use cases of the viewlet system. In the following example, we are going to develop a generic contents view for files. The step is to create a file component: >>> class IFile(zope.interface.Interface): ... data = zope.interface.Attribute('Data of file.') >>> class File(object): ... zope.interface.implements(IFile) ... def __init__(self, data=''): ... self.__name__ = '' ... self.data = data Since we want to also provide the size of a file, here a simple implementation of the ``ISized`` interface: >>> from zope import size >>> class FileSized(object): ... zope.interface.implements(size.interfaces.ISized) ... zope.component.adapts(IFile) ... ... def __init__(self, file): ... self.file = file ... ... def sizeForSorting(self): ... return 'byte', len(self.file.data) ... ... def sizeForDisplay(self): ... return '%i bytes' %len(self.file.data) >>> zope.component.provideAdapter(FileSized) We also need a container to which we can add files: >>> class Container(dict): ... def __setitem__(self, name, value): ... value.__name__ = name ... super(Container, self).__setitem__(name, value) Here is some sample data: >>> container = Container() >>> container['test.txt'] = File('Hello World!') >>> container['mypage.html'] = File('Hello World!') >>> container['data.xml'] = File('Hello World!') The View ~~~~~~~~ The contents view of the container should iterate through the container and represent the files in a table: >>> contentsTemplate = os.path.join(temp_dir, 'contents.pt') >>> open(contentsTemplate, 'w').write(''' ... ... ...

    Contents

    ...
    ... ... ... ''') >>> from zope.browserpage.simpleviewclass import SimpleViewClass >>> Contents = SimpleViewClass(contentsTemplate, name='contents.html') The Viewlet Manager ~~~~~~~~~~~~~~~~~~~ Now we have to write our own viewlet manager. In this case we cannot use the default implementation, since the viewlets will be looked up for each different item: >>> shownColumns = [] >>> class ContentsViewletManager(object): ... zope.interface.implements(interfaces.IViewletManager) ... index = None ... ... def __init__(self, context, request, view): ... self.context = context ... self.request = request ... self.__parent__ = view ... ... def update(self): ... rows = [] ... for name, value in self.context.items(): ... rows.append( ... [zope.component.getMultiAdapter( ... (value, self.request, self.__parent__, self), ... interfaces.IViewlet, name=colname) ... for colname in shownColumns]) ... [entry.update() for entry in rows[-1]] ... self.rows = rows ... ... def render(self, *args, **kw): ... return self.index(*args, **kw) Now we need a template to produce the contents table: >>> tableTemplate = os.path.join(temp_dir, 'table.pt') >>> open(tableTemplate, 'w').write(''' ... ... ... ... ...
    ... ...
    ... ''') From the two pieces above, we can generate the final viewlet manager class and register it (it's a bit tedious, I know): >>> from zope.browserpage import ViewPageTemplateFile >>> ContentsViewletManager = type( ... 'ContentsViewletManager', (ContentsViewletManager,), ... {'index': ViewPageTemplateFile(tableTemplate)}) >>> zope.component.provideAdapter( ... ContentsViewletManager, ... (Container, IDefaultBrowserLayer, zope.interface.Interface), ... interfaces.IViewletManager, name='contents') Since we have not defined any viewlets yet, the table is totally empty: >>> contents = Contents(container, request) >>> print contents().strip()

    Contents

    The Viewlets and the Final Result ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Now let's create a first viewlet for the manager... >>> class NameViewlet(object): ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... self.context = context ... ... def update(self): ... pass ... ... def render(self): ... return self.context.__name__ and register it: >>> zope.component.provideAdapter( ... NameViewlet, ... (IFile, IDefaultBrowserLayer, ... zope.interface.Interface, interfaces.IViewletManager), ... interfaces.IViewlet, name='name') Note how you register the viewlet on ``IFile`` and not on the container. Now we should be able to see the name for each file in the container: >>> print contents().strip()

    Contents

    Waaa, nothing there! What happened? Well, we have to tell our user preferences that we want to see the name as a column in the table: >>> shownColumns = ['name'] >>> print contents().strip()

    Contents

    mypage.html
    data.xml
    test.txt
    Let's now write a second viewlet that will display the size of the object for us: >>> class SizeViewlet(object): ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... self.context = context ... ... def update(self): ... pass ... ... def render(self): ... return size.interfaces.ISized(self.context).sizeForDisplay() >>> zope.component.provideAdapter( ... SizeViewlet, ... (IFile, IDefaultBrowserLayer, ... zope.interface.Interface, interfaces.IViewletManager), ... interfaces.IViewlet, name='size') After we added it to the list of shown columns, >>> shownColumns = ['name', 'size'] we can see an entry for it: >>> print contents().strip()

    Contents

    mypage.html 38 bytes
    data.xml 31 bytes
    test.txt 12 bytes
    If we switch the two columns around, >>> shownColumns = ['size', 'name'] the result will be >>> print contents().strip()

    Contents

    38 bytes mypage.html
    31 bytes data.xml
    12 bytes test.txt
    Supporting Sorting ~~~~~~~~~~~~~~~~~~ Oftentimes you also want to batch and sort the entries in a table. Since those two features are not part of the view logic, they should be treated with independent components. In this example, we are going to only implement sorting using a simple utility: >>> class ISorter(zope.interface.Interface): ... ... def sort(values): ... """Sort the values.""" >>> class SortByName(object): ... zope.interface.implements(ISorter) ... ... def sort(self, values): ... return sorted(values, lambda x, y: cmp(x.__name__, y.__name__)) >>> zope.component.provideUtility(SortByName(), name='name') >>> class SortBySize(object): ... zope.interface.implements(ISorter) ... ... def sort(self, values): ... return sorted( ... values, ... lambda x, y: cmp(size.interfaces.ISized(x).sizeForSorting(), ... size.interfaces.ISized(y).sizeForSorting())) >>> zope.component.provideUtility(SortBySize(), name='size') Note that we decided to give the sorter utilities the same name as the corresponding viewlet. This convention will make our implementation of the viewlet manager much simpler: >>> sortByColumn = '' >>> class SortedContentsViewletManager(object): ... zope.interface.implements(interfaces.IViewletManager) ... index = None ... ... def __init__(self, context, request, view): ... self.context = context ... self.request = request ... self.__parent__ = view ... ... def update(self): ... values = self.context.values() ... ... if sortByColumn: ... sorter = zope.component.queryUtility(ISorter, sortByColumn) ... if sorter: ... values = sorter.sort(values) ... ... rows = [] ... for value in values: ... rows.append( ... [zope.component.getMultiAdapter( ... (value, self.request, self.__parent__, self), ... interfaces.IViewlet, name=colname) ... for colname in shownColumns]) ... [entry.update() for entry in rows[-1]] ... self.rows = rows ... ... def render(self, *args, **kw): ... return self.index(*args, **kw) As you can see, the concern of sorting is cleanly separated from generating the view code. In MVC terms that means that the controller (sort) is logically separated from the view (viewlets). Let's now do the registration dance for the new viewlet manager. We simply override the existing registration: >>> SortedContentsViewletManager = type( ... 'SortedContentsViewletManager', (SortedContentsViewletManager,), ... {'index': ViewPageTemplateFile(tableTemplate)}) >>> zope.component.provideAdapter( ... SortedContentsViewletManager, ... (Container, IDefaultBrowserLayer, zope.interface.Interface), ... interfaces.IViewletManager, name='contents') Finally we sort the contents by name: >>> shownColumns = ['name', 'size'] >>> sortByColumn = 'name' >>> print contents().strip()

    Contents

    data.xml 31 bytes
    mypage.html 38 bytes
    test.txt 12 bytes
    Now let's sort by size: >>> sortByColumn = 'size' >>> print contents().strip()

    Contents

    test.txt 12 bytes
    data.xml 31 bytes
    mypage.html 38 bytes
    That's it! As you can see, in a few steps we have built a pretty flexible contents view with selectable columns and sorting. However, there is a lot of room for extending this example: - Table Header: The table header cell for each column should be a different type of viewlet, but registered under the same name. The column header viewlet also adapts the container not the item. The header column should also be able to control the sorting. - Batching: A simple implementation of batching should work very similar to the sorting feature. Of course, efficient implementations should somehow combine batching and sorting more effectively. - Sorting in ascending and descending order: Currently, you can only sort from the smallest to the highest value; however, this limitation is almost superficial and can easily be removed by making the sorters a bit more flexible. - Further Columns: For a real application, you would want to implement other columns, of course. You would also probably want some sort of fallback for the case that a viewlet is not found for a particular container item and column. Cleanup ------- >>> import shutil >>> shutil.rmtree(temp_dir) ================================ The ``viewletManager`` Directive ================================ The ``viewletManager`` directive allows you to quickly register a new viewlet manager without worrying about the details of the ``adapter`` directive. Before we can use the directives, we have to register their handlers by executing the package's meta configuration: >>> from zope.configuration import xmlconfig >>> context = xmlconfig.string(''' ... ... ... ... ''') Now we can register a viewlet manager: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Let's make sure the directive has really issued a sensible adapter registration; to do that, we create some dummy content, request and view objects: >>> import zope.interface >>> class Content(object): ... zope.interface.implements(zope.interface.Interface) >>> content = Content() >>> from zope.publisher.browser import TestRequest >>> request = TestRequest() >>> from zope.publisher.browser import BrowserView >>> view = BrowserView(content, request) Now let's lookup the manager. This particular registration is pretty boring: >>> import zope.component >>> from zope.viewlet import interfaces >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ... interfaces.IViewletManager, name='defaultmanager') >>> manager object ...> >>> interfaces.IViewletManager.providedBy(manager) True >>> manager.template is None True >>> manager.update() >>> manager.render() u'' However, this registration is not very useful, since we did specify a specific viewlet manager interface, a specific content interface, specific view or specific layer. This means that all viewlets registered will be found. The first step to effectively using the viewlet manager directive is to define a special viewlet manager interface: >>> class ILeftColumn(interfaces.IViewletManager): ... """Left column of my page.""" Now we can register register a manager providing this interface: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> ILeftColumn.providedBy(manager) True >>> manager.template is None True >>> manager.update() >>> manager.render() u'' Next let's see what happens, if we specify a template for the viewlet manager: >>> import os, tempfile >>> temp_dir = tempfile.mkdtemp() >>> leftColumnTemplate = os.path.join(temp_dir, 'leftcolumn.pt') >>> open(leftColumnTemplate, 'w').write(''' ...
    ...
    ...
    ... ''') >>> context = xmlconfig.string(''' ... ... ... ... ''' %leftColumnTemplate, context=context) >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> ILeftColumn.providedBy(manager) True >>> manager.template ...>> >>> manager.update() >>> print manager.render().strip()
    Additionally you can specify a class that will serve as a base to the default viewlet manager or be a viewlet manager in its own right. In our case we will provide a custom implementation of the ``sort()`` method, which will sort by a weight attribute in the viewlet: >>> class WeightBasedSorting(object): ... def sort(self, viewlets): ... return sorted(viewlets, ... lambda x, y: cmp(x[1].weight, y[1].weight)) >>> context = xmlconfig.string(''' ... ... ... ... ''' %leftColumnTemplate, context=context) >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> manager.__class__.__bases__ (, ) >>> ILeftColumn.providedBy(manager) True >>> manager.template ...>> >>> manager.update() >>> print manager.render().strip()
    Finally, if a non-existent template is specified, an error is raised: >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 3.2-7.8 ConfigurationError: ('No such file', '...foo.pt') ========================= The ``viewlet`` Directive ========================= Now that we have a viewlet manager, we have to register some viewlets for it. The ``viewlet`` directive is similar to the ``viewletManager`` directive, except that the viewlet is also registered for a particular manager interface, as seen below: >>> weatherTemplate = os.path.join(temp_dir, 'weather.pt') >>> open(weatherTemplate, 'w').write(''' ...
    sunny
    ... ''') >>> context = xmlconfig.string(''' ... ... ... ... ''' % weatherTemplate, context=context) If we look into the adapter registry, we will find the viewlet: >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='weather') >>> viewlet.render().strip() u'
    sunny
    ' >>> viewlet.extra_string_attributes u'can be specified' The manager now also gives us the output of the one and only viewlet: >>> manager.update() >>> print manager.render().strip()
    sunny
    Let's now ensure that we can also specify a viewlet class: >>> class Weather(object): ... weight = 0 >>> context = xmlconfig.string(''' ... ... ... ... ''' % weatherTemplate, context=context) >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='weather2') >>> viewlet().strip() u'
    sunny
    ' Okay, so the template-driven cases work. But just specifying a class should also work: >>> class Sport(object): ... weight = 0 ... def __call__(self): ... return u'Red Sox vs. White Sox' >>> context = xmlconfig.string(''' ... ... ... ... ''', context=context) >>> viewlet = zope.component.getMultiAdapter( ...

The second file can be recovered similarly, but by retaining only " " and "+ " lines; use ndiff with -r2; or, on Unix, the second file can be recovered by piping the output through sed -n '/^[+ ] /s/^..//p' See module comments for details and programmatic interface. $Id: ndiff.py 38178 2005-08-30 21:50:19Z mj $ """ __version__ = 1, 5, 0 # SequenceMatcher tries to compute a "human-friendly diff" between # two sequences (chiefly picturing a file as a sequence of lines, # and a line as a sequence of characters, here). Unlike e.g. UNIX(tm) # diff, the fundamental notion is the longest *contiguous* & junk-free # matching subsequence. That's what catches peoples' eyes. The # Windows(tm) windiff has another interesting notion, pairing up elements # that appear uniquely in each sequence. That, and the method here, # appear to yield more intuitive difference reports than does diff. This # method appears to be the least vulnerable to synching up on blocks # of "junk lines", though (like blank lines in ordinary text files, # or maybe "

    " lines in HTML files). That may be because this is # the only method of the 3 that has a *concept* of "junk" . # # Note that ndiff makes no claim to produce a *minimal* diff. To the # contrary, minimal diffs are often counter-intuitive, because they # synch up anywhere possible, sometimes accidental matches 100 pages # apart. Restricting synch points to contiguous matches preserves some # notion of locality, at the occasional cost of producing a longer diff. # # With respect to junk, an earlier version of ndiff simply refused to # *start* a match with a junk element. The result was cases like this: # before: private Thread currentThread; # after: private volatile Thread currentThread; # If you consider whitespace to be junk, the longest contiguous match # not starting with junk is "e Thread currentThread". So ndiff reported # that "e volatil" was inserted between the 't' and the 'e' in "private". # While an accurate view, to people that's absurd. The current version # looks for matching blocks that are entirely junk-free, then extends the # longest one of those as far as possible but only with matching junk. # So now "currentThread" is matched, then extended to suck up the # preceding blank; then "private" is matched, and extended to suck up the # following blank; then "Thread" is matched; and finally ndiff reports # that "volatile " was inserted before "Thread". The only quibble # remaining is that perhaps it was really the case that " volatile" # was inserted after "private". I can live with that . # # NOTE on junk: the module-level names # IS_LINE_JUNK # IS_CHARACTER_JUNK # can be set to any functions you like. The first one should accept # a single string argument, and return true iff the string is junk. # The default is whether the regexp r"\s*#?\s*$" matches (i.e., a # line without visible characters, except for at most one splat). # The second should accept a string of length 1 etc. The default is # whether the character is a blank or tab (note: bad idea to include # newline in this!). # # After setting those, you can call fcompare(f1name, f2name) with the # names of the files you want to compare. The difference report # is sent to stdout. Or you can call main(args), passing what would # have been in sys.argv[1:] had the cmd-line form been used.

It also includes the Macro Expansion for TAL (METAL) macro language used in page assembly. The dynamic values themselves are specified using a companion language, TALES (see the 'zope.tales' package for more). See: http://www.zope.org/Wikis/DevSite/Projects/ZPT/TAL%20Specification%201.4 ======= CHANGES ======= 3.5.2 (2009-10-31) ------------------ - In talgettext.POEngine.translate, print a warning if a msgid already exists in the domain with a different default. 3.5.1 (2009-03-08) ------------------ - Updated tests of "bad" entities for compatibility with the stricter HTMLParser module shipped with Python 2.6.x. 3.5.0 (2008-06-06) ------------------ - Removed artificial addition of a trailing newline if the output doesn't end in one; this allows the template source to be the full specification of what should be included. (See https://bugs.launchpad.net/launchpad/+bug/218706.) 3.4.1 (2007-11-16) ------------------ - Removed unnecessary ``dummyengine`` dependency on zope.i18n to simplify distribution. The ``dummyengine.DummyTranslationDomain`` class no longer implements ``zope.i18n.interfaces.ITranslationDomain`` as a result. Installing zope.tal with easy_install or buildout no longer pulls in many unrelated distributions. - Support ability to run tests using "setup.py test". - Stop pinning (no longer required) zope.traversing and zope.app.publisher versions in buildout.cfg. 3.4.0 (2007-10-03) ------------------ - Updated package meta-data. 3.4.0b1 ------- - Updated dependency for ``zope.i18n`` that requires the correct version of zope.security to avoid a hidden dependency issue in zope.security. Note: The code changes before 3.4.0b1 where not tracked as an individual package and have been documented in the Zope 3 changelog.

Home-page: http://pypi.python.org/pypi/Acquisition Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: .. contents:: Introductory Example ==================== Zope implements acquisition with "Extension Class" mix-in classes. To use acquisition your classes must inherit from an acquisition base class. For example:: >>> import ExtensionClass, Acquisition >>> class C(ExtensionClass.Base): ... color='red' >>> class A(Acquisition.Implicit): ... def report(self): ... print self.color ... >>> a = A() >>> c = C() >>> c.a = a >>> c.a.report() red >>> d = C() >>> d.color = 'green' >>> d.a = a >>> d.a.report() green >>> a.report() # raises an attribute error Traceback (most recent call last): ... AttributeError: color The class ``A`` inherits acquisition behavior from ``Acquisition.Implicit``. The object, ``a``, "has" the color of objects ``c`` and d when it is accessed through them, but it has no color by itself. The object ``a`` obtains attributes from its environment, where its environment is defined by the access path used to reach ``a``. Acquisition Wrappers ==================== When an object that supports acquisition is accessed through an extension class instance, a special object, called an acquisition wrapper, is returned. In the example above, the expression ``c.a`` returns an acquisition wrapper that contains references to both ``c`` and ``a``. It is this wrapper that performs attribute lookup in ``c`` when an attribute cannot be found in ``a``. Acquisition wrappers provide access to the wrapped objects through the attributes ``aq_parent``, ``aq_self``, ``aq_base``. Continue the example from above:: >>> c.a.aq_parent is c True >>> c.a.aq_self is a True Explicit and Implicit Acquisition ================================= Two styles of acquisition are supported: implicit and explicit acquisition. Implicit acquisition -------------------- Implicit acquisition is so named because it searches for attributes from the environment automatically whenever an attribute cannot be obtained directly from an object or through inheritance. An attribute can be implicitly acquired if its name does not begin with an underscore. To support implicit acquisition, your class should inherit from the mix-in class ``Acquisition.Implicit``. Explicit Acquisition -------------------- When explicit acquisition is used, attributes are not automatically obtained from the environment. Instead, the method aq_acquire must be used. For example:: >>> print c.a.aq_acquire('color') red To support explicit acquisition, your class should inherit from the mix-in class ``Acquisition.Explicit``. Controlling Acquisition ----------------------- A class (or instance) can provide attribute by attribute control over acquisition. Your should subclass from ``Acquisition.Explicit``, and set all attributes that should be acquired to the special value ``Acquisition.Acquired``. Setting an attribute to this value also allows inherited attributes to be overridden with acquired ones. For example:: >>> class C(Acquisition.Explicit): ... id=1 ... secret=2 ... color=Acquisition.Acquired ... __roles__=Acquisition.Acquired The only attributes that are automatically acquired from containing objects are color, and ``__roles__``. Note that the ``__roles__`` attribute is acquired even though its name begins with an underscore. In fact, the special ``Acquisition.Acquired`` value can be used in ``Acquisition.Implicit`` objects to implicitly acquire selected objects that smell like private objects. Sometimes, you want to dynamically make an implicitly acquiring object acquire explicitly. You can do this by getting the object's aq_explicit attribute. This attribute provides the object with an explicit wrapper that replaces the original implicit wrapper. Filtered Acquisition ==================== The acquisition method, ``aq_acquire``, accepts two optional arguments. The first of the additional arguments is a "filtering" function that is used when considering whether to acquire an object. The second of the additional arguments is an object that is passed as extra data when calling the filtering function and which defaults to ``None``. The filter function is called with five arguments: * The object that the aq_acquire method was called on, * The object where an object was found, * The name of the object, as passed to aq_acquire, * The object found, and * The extra data passed to aq_acquire. If the filter returns a true object that the object found is returned, otherwise, the acquisition search continues. Here's an example:: >>> from Acquisition import Explicit >>> class HandyForTesting: ... def __init__(self, name): ... self.name = name ... def __str__(self): ... return "%s(%s)" % (self.name, self.__class__.__name__) ... __repr__=__str__ ... >>> class E(Explicit, HandyForTesting): pass ... >>> class Nice(HandyForTesting): ... isNice= 1 ... def __str__(self): ... return HandyForTesting.__str__(self)+' and I am nice!' ... __repr__=__str__ ... >>> a = E('a') >>> a.b = E('b') >>> a.b.c = E('c') >>> a.p = Nice('spam') >>> a.b.p = E('p') >>> def find_nice(self, ancestor, name, object, extra): ... return hasattr(object,'isNice') and object.isNice >>> print a.b.c.aq_acquire('p', find_nice) spam(Nice) and I am nice! The filtered acquisition in the last line skips over the first attribute it finds with the name ``p``, because the attribute doesn't satisfy the condition given in the filter. Filtered acquisition is rarely used in Zope. Acquiring from Context ====================== Normally acquisition allows objects to acquire data from their containers. However an object can acquire from objects that aren't its containers. Most of the examples we've seen so far show establishing of an acquisition context using getattr semantics. For example, ``a.b`` is a reference to ``b`` in the context of ``a``. You can also manually set acquisition context using the ``__of__`` method. For example:: >>> from Acquisition import Implicit >>> class C(Implicit): pass ... >>> a = C() >>> b = C() >>> a.color = "red" >>> print b.__of__(a).color red In this case, ``a`` does not contain ``b``, but it is put in ``b``'s context using the ``__of__`` method. Here's another subtler example that shows how you can construct an acquisition context that includes non-container objects:: >>> from Acquisition import Implicit >>> class C(Implicit): ... def __init__(self, name): ... self.name = name >>> a = C("a") >>> a.b = C("b") >>> a.b.color = "red" >>> a.x = C("x") >>> print a.b.x.color red Even though ``b`` does not contain ``x``, ``x`` can acquire the color attribute from ``b``. This works because in this case, ``x`` is accessed in the context of ``b`` even though it is not contained by ``b``. Here acquisition context is defined by the objects used to access another object. Containment Before Context ========================== If in the example above suppose both a and b have an color attribute:: >>> a = C("a") >>> a.color = "green" >>> a.b = C("b") >>> a.b.color = "red" >>> a.x = C("x") >>> print a.b.x.color green Why does ``a.b.x.color`` acquire color from ``a`` and not from ``b``? The answer is that an object acquires from its containers before non-containers in its context. To see why consider this example in terms of expressions using the ``__of__`` method:: a.x -> x.__of__(a) a.b -> b.__of__(a) a.b.x -> x.__of__(a).__of__(b.__of__(a)) Keep in mind that attribute lookup in a wrapper is done by trying to look up the attribute in the wrapped object first and then in the parent object. So in the expressions above proceeds from left to right. The upshot of these rules is that attributes are looked up by containment before context. This rule holds true also for more complex examples. For example, ``a.b.c.d.e.f.g.attribute`` would search for attribute in ``g`` and all its containers first. (Containers are searched in order from the innermost parent to the outermost container.) If the attribute is not found in ``g`` or any of its containers, then the search moves to ``f`` and all its containers, and so on. Additional Attributes and Methods ================================= You can use the special method ``aq_inner`` to access an object wrapped only by containment. So in the example above, ``a.b.x.aq_inner`` is equivalent to ``a.x``. You can find out the acquisition context of an object using the aq_chain method like so: >>> [obj.name for obj in a.b.x.aq_chain] ['x', 'b', 'a'] You can find out if an object is in the containment context of another object using the ``aq_inContextOf`` method. For example: >>> a.b.aq_inContextOf(a) 1 .. Note: as of this writing the aq_inContextOf examples don't work the way they should be working. According to Jim, this is because aq_inContextOf works by comparing object pointer addresses, which (because they are actually different wrapper objects) doesn't give you the expected results. He acknowledges that this behavior is controversial, and says that there is a collector entry to change it so that you would get the answer you expect in the above. (We just need to get to it). Acquisition Module Functions ============================ In addition to using acquisition attributes and methods directly on objects you can use similar functions defined in the ``Acquisition`` module. These functions have the advantage that you don't need to check to make sure that the object has the method or attribute before calling it. ``aq_acquire(object, name [, filter, extra, explicit, default, containment])`` Acquires an object with the given name. This function can be used to explictly acquire when using explicit acquisition and to acquire names that wouldn't normally be acquired. The function accepts a number of optional arguments: ``filter`` A callable filter object that is used to decide if an object should be acquired. The filter is called with five arguments: * The object that the aq_acquire method was called on, * The object where an object was found, * The name of the object, as passed to aq_acquire, * The object found, and * The extra argument passed to aq_acquire. If the filter returns a true object that the object found is returned, otherwise, the acquisition search continues. ``extra`` Extra data to be passed as the last argument to the filter. ``explicit`` A flag (boolean value) indicating whether explicit acquisition should be used. The default value is true. If the flag is true, then acquisition will proceed regardless of whether wrappers encountered in the search of the acquisition hierarchy are explicit or implicit wrappers. If the flag is false, then parents of explicit wrappers are not searched. This argument is useful if you want to apply a filter without overriding explicit wrappers. ``default`` A default value to return if no value can be acquired. ``containment`` A flag indicating whether the search should be limited to the containment hierarchy. In addition, arguments can be provided as keywords. ``aq_base(object)`` Return the object with all wrapping removed. ``aq_chain(object [, containment])`` Return a list containing the object and it's acquisition parents. The optional argument, containment, controls whether the containment or access hierarchy is used. ``aq_get(object, name [, default, containment])`` Acquire an attribute, name. A default value can be provided, as can a flag that limits search to the containment hierarchy. ``aq_inner(object)`` Return the object with all but the innermost layer of wrapping removed. ``aq_parent(object)`` Return the acquisition parent of the object or None if the object is unwrapped. ``aq_self(object)`` Return the object with one layer of wrapping removed, unless the object is unwrapped, in which case the object is returned. In most cases it is more convenient to use these module functions instead of the acquisition attributes and methods directly. Acquisition and Methods ======================= Python methods of objects that support acquisition can use acquired attributes. When a Python method is called on an object that is wrapped by an acquisition wrapper, the wrapper is passed to the method as the first argument. This rule also applies to user-defined method types and to C methods defined in pure mix-in classes. Unfortunately, C methods defined in extension base classes that define their own data structures, cannot use aquired attributes at this time. This is because wrapper objects do not conform to the data structures expected by these methods. In practice, you will seldom find this a problem. Conclusion ========== Acquisition provides a powerful way to dynamically share information between objects. Zope 2 uses acquisition for a number of its key features including security, object publishing, and DTML variable lookup. Acquisition also provides an elegant solution to the problem of circular references for many classes of problems. While acquisition is powerful, you should take care when using acquisition in your applications. The details can get complex, especially with the differences between acquiring from context and acquiring from containment. Changelog ========= 2.13.8 (2011-06-11) ------------------- - Fixed a segfault on 64bit platforms when providing the `explicit` argument to the aq_acquire method of an Acquisition wrapper. Thx to LP #675064 for the hint to the solution. The code passed an int instead of a pointer into a function. 2.13.7 (2011-03-02) ------------------- - Fixed bug: When an object did not implement ``__unicode__``, calling ``unicode(wrapped)`` was calling ``__str__`` with an unwrapped ``self``. 2.13.6 (2011-02-19) ------------------- - Add ``aq_explicit`` to ``IAcquisitionWrapper``. - Fixed bug: ``unicode(wrapped)`` was not calling a ``__unicode__`` method on wrapped objects. 2.13.5 (2010-09-29) ------------------- - Fixed unit tests that failed on 64bit Python on Windows machines. 2.13.4 (2010-08-31) ------------------- - LP 623665: Fixed typo in Acquisition.h. 2.13.3 (2010-04-19) ------------------- - Use the doctest module from the standard library and no longer depend on zope.testing. 2.13.2 (2010-04-04) ------------------- - Give both wrapper classes a ``__getnewargs__`` method, which causes the ZODB optimization to fail and create persistent references using the ``_p_oid`` alone. This happens to be the persistent oid of the wrapped object. This lets these objects to be persisted correctly, even though they are passed to the ZODB in a wrapped state. - Added failing tests for http://dev.plone.org/plone/ticket/10318. This shows an edge-case where AQ wrappers can be pickled using the specific combination of cPickle, pickle protocol one and a custom Pickler class with an ``inst_persistent_id`` hook. Unfortunately this is the exact combination used by ZODB3. 2.13.1 (2010-02-23) ------------------- - Update to include ExtensionClass 2.13.0. - Fix the ``tp_name`` of the ImplicitAcquisitionWrapper and ExplicitAcquisitionWrapper to match their Python visible names and thus have a correct ``__name__``. - Expand the ``tp_name`` of our extension types to hold the fully qualified name. This ensures classes have their ``__module__`` set correctly. 2.13.0 (2010-02-14) ------------------- - Added support for method cache in Acquisition. Patch contributed by Yoshinori K. Okuji. See https://bugs.launchpad.net/zope2/+bug/486182. 2.12.4 (2009-10-29) ------------------- - Fix iteration proxying to pass `self` acquisition-wrapped into both `__iter__` as well as `__getitem__` (this fixes https://bugs.launchpad.net/zope2/+bug/360761). - Add tests for the __getslice__ proxying, including open-ended slicing. 2.12.3 (2009-08-08) ------------------- - More 64-bit fixes in Py_BuildValue calls. - More 64-bit issues fixed: Use correct integer size for slice operations. 2.12.2 (2009-08-02) ------------------- - Fixed 64-bit compatibility issues for Python 2.5.x / 2.6.x. See http://www.python.org/dev/peps/pep-0353/ for details. 2.12.1 (2009-04-15) ------------------- - Update for iteration proxying: The proxy for `__iter__` must not rely on the object to have an `__iter__` itself, but also support fall-back iteration via `__getitem__` (this fixes https://bugs.launchpad.net/zope2/+bug/360761). 2.12 (2009-01-25) ----------------- - Release as separate package.

Home-page: http://pypi.python.org/pypi/Acquisition Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: .. contents:: Introductory Example ==================== Zope implements acquisition with "Extension Class" mix-in classes. To use acquisition your classes must inherit from an acquisition base class. For example:: >>> import ExtensionClass, Acquisition >>> class C(ExtensionClass.Base): ... color='red' >>> class A(Acquisition.Implicit): ... def report(self): ... print self.color ... >>> a = A() >>> c = C() >>> c.a = a >>> c.a.report() red >>> d = C() >>> d.color = 'green' >>> d.a = a >>> d.a.report() green >>> a.report() # raises an attribute error Traceback (most recent call last): ... AttributeError: color The class ``A`` inherits acquisition behavior from ``Acquisition.Implicit``. The object, ``a``, "has" the color of objects ``c`` and d when it is accessed through them, but it has no color by itself. The object ``a`` obtains attributes from its environment, where its environment is defined by the access path used to reach ``a``. Acquisition Wrappers ==================== When an object that supports acquisition is accessed through an extension class instance, a special object, called an acquisition wrapper, is returned. In the example above, the expression ``c.a`` returns an acquisition wrapper that contains references to both ``c`` and ``a``. It is this wrapper that performs attribute lookup in ``c`` when an attribute cannot be found in ``a``. Acquisition wrappers provide access to the wrapped objects through the attributes ``aq_parent``, ``aq_self``, ``aq_base``. Continue the example from above:: >>> c.a.aq_parent is c True >>> c.a.aq_self is a True Explicit and Implicit Acquisition ================================= Two styles of acquisition are supported: implicit and explicit acquisition. Implicit acquisition -------------------- Implicit acquisition is so named because it searches for attributes from the environment automatically whenever an attribute cannot be obtained directly from an object or through inheritance. An attribute can be implicitly acquired if its name does not begin with an underscore. To support implicit acquisition, your class should inherit from the mix-in class ``Acquisition.Implicit``. Explicit Acquisition -------------------- When explicit acquisition is used, attributes are not automatically obtained from the environment. Instead, the method aq_acquire must be used. For example:: >>> print c.a.aq_acquire('color') red To support explicit acquisition, your class should inherit from the mix-in class ``Acquisition.Explicit``. Controlling Acquisition ----------------------- A class (or instance) can provide attribute by attribute control over acquisition. Your should subclass from ``Acquisition.Explicit``, and set all attributes that should be acquired to the special value ``Acquisition.Acquired``. Setting an attribute to this value also allows inherited attributes to be overridden with acquired ones. For example:: >>> class C(Acquisition.Explicit): ... id=1 ... secret=2 ... color=Acquisition.Acquired ... __roles__=Acquisition.Acquired The only attributes that are automatically acquired from containing objects are color, and ``__roles__``. Note that the ``__roles__`` attribute is acquired even though its name begins with an underscore. In fact, the special ``Acquisition.Acquired`` value can be used in ``Acquisition.Implicit`` objects to implicitly acquire selected objects that smell like private objects. Sometimes, you want to dynamically make an implicitly acquiring object acquire explicitly. You can do this by getting the object's aq_explicit attribute. This attribute provides the object with an explicit wrapper that replaces the original implicit wrapper. Filtered Acquisition ==================== The acquisition method, ``aq_acquire``, accepts two optional arguments. The first of the additional arguments is a "filtering" function that is used when considering whether to acquire an object. The second of the additional arguments is an object that is passed as extra data when calling the filtering function and which defaults to ``None``. The filter function is called with five arguments: * The object that the aq_acquire method was called on, * The object where an object was found, * The name of the object, as passed to aq_acquire, * The object found, and * The extra data passed to aq_acquire. If the filter returns a true object that the object found is returned, otherwise, the acquisition search continues. Here's an example:: >>> from Acquisition import Explicit >>> class HandyForTesting: ... def __init__(self, name): ... self.name = name ... def __str__(self): ... return "%s(%s)" % (self.name, self.__class__.__name__) ... __repr__=__str__ ... >>> class E(Explicit, HandyForTesting): pass ... >>> class Nice(HandyForTesting): ... isNice= 1 ... def __str__(self): ... return HandyForTesting.__str__(self)+' and I am nice!' ... __repr__=__str__ ... >>> a = E('a') >>> a.b = E('b') >>> a.b.c = E('c') >>> a.p = Nice('spam') >>> a.b.p = E('p') >>> def find_nice(self, ancestor, name, object, extra): ... return hasattr(object,'isNice') and object.isNice >>> print a.b.c.aq_acquire('p', find_nice) spam(Nice) and I am nice! The filtered acquisition in the last line skips over the first attribute it finds with the name ``p``, because the attribute doesn't satisfy the condition given in the filter. Filtered acquisition is rarely used in Zope. Acquiring from Context ====================== Normally acquisition allows objects to acquire data from their containers. However an object can acquire from objects that aren't its containers. Most of the examples we've seen so far show establishing of an acquisition context using getattr semantics. For example, ``a.b`` is a reference to ``b`` in the context of ``a``. You can also manually set acquisition context using the ``__of__`` method. For example:: >>> from Acquisition import Implicit >>> class C(Implicit): pass ... >>> a = C() >>> b = C() >>> a.color = "red" >>> print b.__of__(a).color red In this case, ``a`` does not contain ``b``, but it is put in ``b``'s context using the ``__of__`` method. Here's another subtler example that shows how you can construct an acquisition context that includes non-container objects:: >>> from Acquisition import Implicit >>> class C(Implicit): ... def __init__(self, name): ... self.name = name >>> a = C("a") >>> a.b = C("b") >>> a.b.color = "red" >>> a.x = C("x") >>> print a.b.x.color red Even though ``b`` does not contain ``x``, ``x`` can acquire the color attribute from ``b``. This works because in this case, ``x`` is accessed in the context of ``b`` even though it is not contained by ``b``. Here acquisition context is defined by the objects used to access another object. Containment Before Context ========================== If in the example above suppose both a and b have an color attribute:: >>> a = C("a") >>> a.color = "green" >>> a.b = C("b") >>> a.b.color = "red" >>> a.x = C("x") >>> print a.b.x.color green Why does ``a.b.x.color`` acquire color from ``a`` and not from ``b``? The answer is that an object acquires from its containers before non-containers in its context. To see why consider this example in terms of expressions using the ``__of__`` method:: a.x -> x.__of__(a) a.b -> b.__of__(a) a.b.x -> x.__of__(a).__of__(b.__of__(a)) Keep in mind that attribute lookup in a wrapper is done by trying to look up the attribute in the wrapped object first and then in the parent object. So in the expressions above proceeds from left to right. The upshot of these rules is that attributes are looked up by containment before context. This rule holds true also for more complex examples. For example, ``a.b.c.d.e.f.g.attribute`` would search for attribute in ``g`` and all its containers first. (Containers are searched in order from the innermost parent to the outermost container.) If the attribute is not found in ``g`` or any of its containers, then the search moves to ``f`` and all its containers, and so on. Additional Attributes and Methods ================================= You can use the special method ``aq_inner`` to access an object wrapped only by containment. So in the example above, ``a.b.x.aq_inner`` is equivalent to ``a.x``. You can find out the acquisition context of an object using the aq_chain method like so: >>> [obj.name for obj in a.b.x.aq_chain] ['x', 'b', 'a'] You can find out if an object is in the containment context of another object using the ``aq_inContextOf`` method. For example: >>> a.b.aq_inContextOf(a) 1 .. Note: as of this writing the aq_inContextOf examples don't work the way they should be working. According to Jim, this is because aq_inContextOf works by comparing object pointer addresses, which (because they are actually different wrapper objects) doesn't give you the expected results. He acknowledges that this behavior is controversial, and says that there is a collector entry to change it so that you would get the answer you expect in the above. (We just need to get to it). Acquisition Module Functions ============================ In addition to using acquisition attributes and methods directly on objects you can use similar functions defined in the ``Acquisition`` module. These functions have the advantage that you don't need to check to make sure that the object has the method or attribute before calling it. ``aq_acquire(object, name [, filter, extra, explicit, default, containment])`` Acquires an object with the given name. This function can be used to explictly acquire when using explicit acquisition and to acquire names that wouldn't normally be acquired. The function accepts a number of optional arguments: ``filter`` A callable filter object that is used to decide if an object should be acquired. The filter is called with five arguments: * The object that the aq_acquire method was called on, * The object where an object was found, * The name of the object, as passed to aq_acquire, * The object found, and * The extra argument passed to aq_acquire. If the filter returns a true object that the object found is returned, otherwise, the acquisition search continues. ``extra`` Extra data to be passed as the last argument to the filter. ``explicit`` A flag (boolean value) indicating whether explicit acquisition should be used. The default value is true. If the flag is true, then acquisition will proceed regardless of whether wrappers encountered in the search of the acquisition hierarchy are explicit or implicit wrappers. If the flag is false, then parents of explicit wrappers are not searched. This argument is useful if you want to apply a filter without overriding explicit wrappers. ``default`` A default value to return if no value can be acquired. ``containment`` A flag indicating whether the search should be limited to the containment hierarchy. In addition, arguments can be provided as keywords. ``aq_base(object)`` Return the object with all wrapping removed. ``aq_chain(object [, containment])`` Return a list containing the object and it's acquisition parents. The optional argument, containment, controls whether the containment or access hierarchy is used. ``aq_get(object, name [, default, containment])`` Acquire an attribute, name. A default value can be provided, as can a flag that limits search to the containment hierarchy. ``aq_inner(object)`` Return the object with all but the innermost layer of wrapping removed. ``aq_parent(object)`` Return the acquisition parent of the object or None if the object is unwrapped. ``aq_self(object)`` Return the object with one layer of wrapping removed, unless the object is unwrapped, in which case the object is returned. In most cases it is more convenient to use these module functions instead of the acquisition attributes and methods directly. Acquisition and Methods ======================= Python methods of objects that support acquisition can use acquired attributes. When a Python method is called on an object that is wrapped by an acquisition wrapper, the wrapper is passed to the method as the first argument. This rule also applies to user-defined method types and to C methods defined in pure mix-in classes. Unfortunately, C methods defined in extension base classes that define their own data structures, cannot use aquired attributes at this time. This is because wrapper objects do not conform to the data structures expected by these methods. In practice, you will seldom find this a problem. Conclusion ========== Acquisition provides a powerful way to dynamically share information between objects. Zope 2 uses acquisition for a number of its key features including security, object publishing, and DTML variable lookup. Acquisition also provides an elegant solution to the problem of circular references for many classes of problems. While acquisition is powerful, you should take care when using acquisition in your applications. The details can get complex, especially with the differences between acquiring from context and acquiring from containment.

New code should use super instead. The base class, Base, exists mainly to support the __of__ protocol.

The basic idea is: I'll call this the "encapsulated base" scheme. Consider: >>> class X(Base): ... pass >>> class Y(Base): ... pass >>> class Z(Base): ... pass >>> class C(X, Y, Z): ... def foo(self): ... return 42 When we look up an attribute, we do the following: - Look in C's dictionary first. - Look up the attribute in X. We don't care how we get the attribute from X. If X is a new-style-class, we use the new algorithm. If X is a classic class, we use left-to-right depth-first. If X is an nsEC, use the "encapsulated base" algorithm. If we don't find the attribute in X, look in Y and then in Z, using the same approach. This algorithm will produce backward compatible results, providing the equivalent of left-to-right depth-first for nsECs and classic classes. We'll actually do something less abstract. We'll use a simple algorthm to merge the __mro__ of the base classes, computing an __mro__ for classic classes using the left-to-right depth-first algorithm. We'll basically lay the mros end-to-end left-to-right and remove repeats, keeping the first occurence of each class. >>> [c.__name__ for c in C.__mro__] ['C', 'X', 'Y', 'Z', 'Base', 'object'] For backward-compatability's sake, we actually depart from the above description a bit. We always put Base and object last in the mro, as shown in the example above. The primary reason for this is that object provides a do-nothing __init__ method. It is common practice to mix a C-implemented base class that implements a few methods with a Python class that implements those methods and others. The idea is that the C implementation overrides selected methods in C, so the C subclass is listed first. Unfortunately, because all extension classes are required to subclass Base, and thus, object, the C subclass brings along the __init__ object from objects, which would hide any __init__ method provided by the Python mix-in. Base and object are special in that they are implied by their meta classes. For example, a new-style class always has object as an ancestor, even if it isn't listed as a base: >>> class O: ... __metaclass__ = type >>> [c.__name__ for c in O.__bases__] ['object'] >>> [c.__name__ for c in O.__mro__] ['O', 'object'] Similarly, Base is always an ancestor of an extension class: >>> class E: ... __metaclass__ = ExtensionClass >>> [c.__name__ for c in E.__bases__] ['Base'] >>> [c.__name__ for c in E.__mro__] ['E', 'Base', 'object'] Base and object are generally added soley to get a particular meta class. They aren't used to provide application functionality and really shouldn't be considered when reasoning about where attributes come from. They do provide some useful default functionality and should be included at the end of the mro. Here are more examples: >>> from ExtensionClass import Base >>> class NA(object): ... pass >>> class NB(NA): ... pass >>> class NC(NA): ... pass >>> class ND(NB, NC): ... pass >>> [c.__name__ for c in ND.__mro__] ['ND', 'NB', 'NC', 'NA', 'object'] >>> class EA(Base): ... pass >>> class EB(EA): ... pass >>> class EC(EA): ... pass >>> class ED(EB, EC): ... pass >>> [c.__name__ for c in ED.__mro__] ['ED', 'EB', 'EA', 'EC', 'Base', 'object'] >>> class EE(ED, ND): ... pass >>> [c.__name__ for c in EE.__mro__] ['EE', 'ED', 'EB', 'EA', 'EC', 'ND', 'NB', 'NC', 'NA', 'Base', 'object'] >>> class EF(ND, ED): ... pass >>> [c.__name__ for c in EF.__mro__] ['EF', 'ND', 'NB', 'NC', 'NA', 'ED', 'EB', 'EA', 'EC', 'Base', 'object'] >>> class CA: ... pass >>> class CB(CA): ... pass >>> class CC(CA): ... pass >>> class CD(CB, CC): ... pass >>> class ECD(Base, CD): ... pass >>> [c.__name__ for c in ECD.__mro__] ['ECD', 'CD', 'CB', 'CA', 'CC', 'Base', 'object'] >>> class CDE(CD, Base): ... pass >>> [c.__name__ for c in CDE.__mro__] ['CDE', 'CD', 'CB', 'CA', 'CC', 'Base', 'object'] >>> class CEND(CD, ED, ND): ... pass >>> [c.__name__ for c in CEND.__mro__] ['CEND', 'CD', 'CB', 'CA', 'CC', """ \ """'ED', 'EB', 'EA', 'EC', 'ND', 'NB', 'NC', 'NA', 'Base', 'object'] """ def test_avoiding___init__decoy_w_inheritedAttribute(): """ >>> class Decoy(Base): ... pass >>> class B(Base): ... def __init__(self, a, b): ... print '__init__', a, b >>> class C(Decoy, B): ... def __init__(self): ... print 'C init' ...

This extra member is a method chain ('PyMethodChain') containing a linked list of method definition ('PyMethodDef') lists. Method chains can be used to implement method inheritance in C. Most extensions don't use method chains, but simply define method lists, which are null-terminated arrays of method definitions. A macro, 'METHOD_CHAIN' is defined in 'ExtensionClass.h' that converts a method list to a method chain. (See the example below.) - Module functions that create new instances must be replaced by an '__init__' method that initializes, but does not create storage for instances. - The extension class must be initialized and exported to the module with:: PyExtensionClass_Export(d,"name",type); where 'name' is the module name and 'type' is the extension class type object. Attribute lookup Attribute lookup is performed by calling the base extension class 'getattr' operation for the base extension class that includes C data, or for the first base extension class, if none of the base extension classes include C data. 'ExtensionClass.h' defines a macro 'Py_FindAttrString' that can be used to find an object's attributes that are stored in the object's instance dictionary or in the object's class or base classes:: v = Py_FindAttrString(self,name); In addition, a macro is provided that replaces 'Py_FindMethod' calls with logic to perform the same sort of lookup that is provided by 'Py_FindAttrString'. Linking The extension class mechanism was designed to be useful with dynamically linked extension modules. Modules that implement extension classes do not have to be linked against an extension class library. The macro 'PyExtensionClass_Export' imports the 'ExtensionClass' module and uses objects imported from this module to initialize an extension class with necessary behavior. */ #ifndef EXTENSIONCLASS_H #define EXTENSIONCLASS_H #include "Python.h" #include "import.h" /* Declarations for objects of type ExtensionClass */ #define EC PyTypeObject #define PyExtensionClass PyTypeObject #define EXTENSIONCLASS_BINDABLE_FLAG 1 << 2 #define EXTENSIONCLASS_NOINSTDICT_FLAG 1 << 5 typedef struct { PyObject_HEAD } _emptyobject; static struct ExtensionClassCAPIstruct { /***************************************************************************** WARNING: THIS STRUCT IS PRIVATE TO THE EXTENSION CLASS INTERFACE IMPLEMENTATION AND IS SUBJECT TO CHANGE !!! *****************************************************************************/ PyObject *(*EC_findiattrs_)(PyObject *self, char *cname); int (*PyExtensionClass_Export_)(PyObject *dict, char *name, PyTypeObject *typ); PyObject *(*PyECMethod_New_)(PyObject *callable, PyObject *inst); PyExtensionClass *ECBaseType_; PyExtensionClass *ECExtensionClassType_; } *PyExtensionClassCAPI = NULL; #define ECBaseType (PyExtensionClassCAPI->ECBaseType_) #define ECExtensionClassType (PyExtensionClassCAPI->ECExtensionClassType_) /* Following are macros that are needed or useful for defining extension classes: */ /* This macro redefines Py_FindMethod to do attribute for an attribute name given by a C string lookup using extension class meta-data.

Thx to LP #675064 for the hint to the solution. The code passed an int instead of a pointer into a function. 2.13.7 (2011-03-02) ------------------- - Fixed bug: When an object did not implement ``__unicode__``, calling ``unicode(wrapped)`` was calling ``__str__`` with an unwrapped ``self``. 2.13.6 (2011-02-19) ------------------- - Add ``aq_explicit`` to ``IAcquisitionWrapper``. - Fixed bug: ``unicode(wrapped)`` was not calling a ``__unicode__`` method on wrapped objects. 2.13.5 (2010-09-29) ------------------- - Fixed unit tests that failed on 64bit Python on Windows machines. 2.13.4 (2010-08-31) ------------------- - LP 623665: Fixed typo in Acquisition.h. 2.13.3 (2010-04-19) ------------------- - Use the doctest module from the standard library and no longer depend on zope.testing. 2.13.2 (2010-04-04) ------------------- - Give both wrapper classes a ``__getnewargs__`` method, which causes the ZODB optimization to fail and create persistent references using the ``_p_oid`` alone. This happens to be the persistent oid of the wrapped object. This lets these objects to be persisted correctly, even though they are passed to the ZODB in a wrapped state. - Added failing tests for http://dev.plone.org/plone/ticket/10318. This shows an edge-case where AQ wrappers can be pickled using the specific combination of cPickle, pickle protocol one and a custom Pickler class with an ``inst_persistent_id`` hook. Unfortunately this is the exact combination used by ZODB3. 2.13.1 (2010-02-23) ------------------- - Update to include ExtensionClass 2.13.0. - Fix the ``tp_name`` of the ImplicitAcquisitionWrapper and ExplicitAcquisitionWrapper to match their Python visible names and thus have a correct ``__name__``. - Expand the ``tp_name`` of our extension types to hold the fully qualified name. This ensures classes have their ``__module__`` set correctly. 2.13.0 (2010-02-14) ------------------- - Added support for method cache in Acquisition. Patch contributed by Yoshinori K. Okuji. See https://bugs.launchpad.net/zope2/+bug/486182. 2.12.4 (2009-10-29) ------------------- - Fix iteration proxying to pass `self` acquisition-wrapped into both `__iter__` as well as `__getitem__` (this fixes https://bugs.launchpad.net/zope2/+bug/360761). - Add tests for the __getslice__ proxying, including open-ended slicing. 2.12.3 (2009-08-08) ------------------- - More 64-bit fixes in Py_BuildValue calls. - More 64-bit issues fixed: Use correct integer size for slice operations. 2.12.2 (2009-08-02) ------------------- - Fixed 64-bit compatibility issues for Python 2.5.x / 2.6.x. See http://www.python.org/dev/peps/pep-0353/ for details. 2.12.1 (2009-04-15) ------------------- - Update for iteration proxying: The proxy for `__iter__` must not rely on the object to have an `__iter__` itself, but also support fall-back iteration via `__getitem__` (this fixes https://bugs.launchpad.net/zope2/+bug/360761). 2.12 (2009-01-25) ----------------- - Release as separate package. zope2.13-2.13.21/source/Acquisition/src/0000755000175000017500000000000012214017433016513 5ustar arnauarnauzope2.13-2.13.21/source/Acquisition/src/Acquisition.egg-info/0000755000175000017500000000000012214017433022475 5ustar arnauarnauzope2.13-2.13.21/source/Acquisition/src/Acquisition.egg-info/PKG-INFO0000644000175000017500000005167112214017433023604 0ustar arnauarnauMetadata-Version: 1.0 Name: Acquisition Version: 2.13.8 Summary: Acquisition is a mechanism that allows objects to obtain attributes from the containment hierarchy they're in. Home-page: http://pypi.python.org/pypi/Acquisition Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: .. contents:: Introductory Example ==================== Zope implements acquisition with "Extension Class" mix-in classes. To use acquisition your classes must inherit from an acquisition base class. For example:: >>> import ExtensionClass, Acquisition >>> class C(ExtensionClass.Base): ... color='red' >>> class A(Acquisition.Implicit): ... def report(self): ... print self.color ... >>> a = A() >>> c = C() >>> c.a = a >>> c.a.report() red >>> d = C() >>> d.color = 'green' >>> d.a = a >>> d.a.report() green >>> a.report() # raises an attribute error Traceback (most recent call last): ... AttributeError: color The class ``A`` inherits acquisition behavior from ``Acquisition.Implicit``. The object, ``a``, "has" the color of objects ``c`` and d when it is accessed through them, but it has no color by itself. The object ``a`` obtains attributes from its environment, where its environment is defined by the access path used to reach ``a``. Acquisition Wrappers ==================== When an object that supports acquisition is accessed through an extension class instance, a special object, called an acquisition wrapper, is returned. In the example above, the expression ``c.a`` returns an acquisition wrapper that contains references to both ``c`` and ``a``. It is this wrapper that performs attribute lookup in ``c`` when an attribute cannot be found in ``a``. Acquisition wrappers provide access to the wrapped objects through the attributes ``aq_parent``, ``aq_self``, ``aq_base``. Continue the example from above:: >>> c.a.aq_parent is c True >>> c.a.aq_self is a True Explicit and Implicit Acquisition ================================= Two styles of acquisition are supported: implicit and explicit acquisition. Implicit acquisition -------------------- Implicit acquisition is so named because it searches for attributes from the environment automatically whenever an attribute cannot be obtained directly from an object or through inheritance. An attribute can be implicitly acquired if its name does not begin with an underscore. To support implicit acquisition, your class should inherit from the mix-in class ``Acquisition.Implicit``. Explicit Acquisition -------------------- When explicit acquisition is used, attributes are not automatically obtained from the environment. Instead, the method aq_acquire must be used. For example:: >>> print c.a.aq_acquire('color') red To support explicit acquisition, your class should inherit from the mix-in class ``Acquisition.Explicit``. Controlling Acquisition ----------------------- A class (or instance) can provide attribute by attribute control over acquisition. Your should subclass from ``Acquisition.Explicit``, and set all attributes that should be acquired to the special value ``Acquisition.Acquired``. Setting an attribute to this value also allows inherited attributes to be overridden with acquired ones. For example:: >>> class C(Acquisition.Explicit): ... id=1 ... secret=2 ... color=Acquisition.Acquired ... __roles__=Acquisition.Acquired The only attributes that are automatically acquired from containing objects are color, and ``__roles__``. Note that the ``__roles__`` attribute is acquired even though its name begins with an underscore. In fact, the special ``Acquisition.Acquired`` value can be used in ``Acquisition.Implicit`` objects to implicitly acquire selected objects that smell like private objects. Sometimes, you want to dynamically make an implicitly acquiring object acquire explicitly. You can do this by getting the object's aq_explicit attribute. This attribute provides the object with an explicit wrapper that replaces the original implicit wrapper. Filtered Acquisition ==================== The acquisition method, ``aq_acquire``, accepts two optional arguments. The first of the additional arguments is a "filtering" function that is used when considering whether to acquire an object. The second of the additional arguments is an object that is passed as extra data when calling the filtering function and which defaults to ``None``. The filter function is called with five arguments: * The object that the aq_acquire method was called on, * The object where an object was found, * The name of the object, as passed to aq_acquire, * The object found, and * The extra data passed to aq_acquire. If the filter returns a true object that the object found is returned, otherwise, the acquisition search continues. Here's an example:: >>> from Acquisition import Explicit >>> class HandyForTesting: ... def __init__(self, name): ... self.name = name ... def __str__(self): ... return "%s(%s)" % (self.name, self.__class__.__name__) ... __repr__=__str__ ... >>> class E(Explicit, HandyForTesting): pass ... >>> class Nice(HandyForTesting): ... isNice= 1 ... def __str__(self): ... return HandyForTesting.__str__(self)+' and I am nice!' ... __repr__=__str__ ... >>> a = E('a') >>> a.b = E('b') >>> a.b.c = E('c') >>> a.p = Nice('spam') >>> a.b.p = E('p') >>> def find_nice(self, ancestor, name, object, extra): ... return hasattr(object,'isNice') and object.isNice >>> print a.b.c.aq_acquire('p', find_nice) spam(Nice) and I am nice! The filtered acquisition in the last line skips over the first attribute it finds with the name ``p``, because the attribute doesn't satisfy the condition given in the filter. Filtered acquisition is rarely used in Zope. Acquiring from Context ====================== Normally acquisition allows objects to acquire data from their containers. However an object can acquire from objects that aren't its containers. Most of the examples we've seen so far show establishing of an acquisition context using getattr semantics. For example, ``a.b`` is a reference to ``b`` in the context of ``a``. You can also manually set acquisition context using the ``__of__`` method. For example:: >>> from Acquisition import Implicit >>> class C(Implicit): pass ... >>> a = C() >>> b = C() >>> a.color = "red" >>> print b.__of__(a).color red In this case, ``a`` does not contain ``b``, but it is put in ``b``'s context using the ``__of__`` method. Here's another subtler example that shows how you can construct an acquisition context that includes non-container objects:: >>> from Acquisition import Implicit >>> class C(Implicit): ... def __init__(self, name): ... self.name = name >>> a = C("a") >>> a.b = C("b") >>> a.b.color = "red" >>> a.x = C("x") >>> print a.b.x.color red Even though ``b`` does not contain ``x``, ``x`` can acquire the color attribute from ``b``. This works because in this case, ``x`` is accessed in the context of ``b`` even though it is not contained by ``b``. Here acquisition context is defined by the objects used to access another object. Containment Before Context ========================== If in the example above suppose both a and b have an color attribute:: >>> a = C("a") >>> a.color = "green" >>> a.b = C("b") >>> a.b.color = "red" >>> a.x = C("x") >>> print a.b.x.color green Why does ``a.b.x.color`` acquire color from ``a`` and not from ``b``? The answer is that an object acquires from its containers before non-containers in its context. To see why consider this example in terms of expressions using the ``__of__`` method:: a.x -> x.__of__(a) a.b -> b.__of__(a) a.b.x -> x.__of__(a).__of__(b.__of__(a)) Keep in mind that attribute lookup in a wrapper is done by trying to look up the attribute in the wrapped object first and then in the parent object. So in the expressions above proceeds from left to right. The upshot of these rules is that attributes are looked up by containment before context. This rule holds true also for more complex examples. For example, ``a.b.c.d.e.f.g.attribute`` would search for attribute in ``g`` and all its containers first. (Containers are searched in order from the innermost parent to the outermost container.) If the attribute is not found in ``g`` or any of its containers, then the search moves to ``f`` and all its containers, and so on. Additional Attributes and Methods ================================= You can use the special method ``aq_inner`` to access an object wrapped only by containment. So in the example above, ``a.b.x.aq_inner`` is equivalent to ``a.x``. You can find out the acquisition context of an object using the aq_chain method like so: >>> [obj.name for obj in a.b.x.aq_chain] ['x', 'b', 'a'] You can find out if an object is in the containment context of another object using the ``aq_inContextOf`` method. For example: >>> a.b.aq_inContextOf(a) 1 .. Note: as of this writing the aq_inContextOf examples don't work the way they should be working. According to Jim, this is because aq_inContextOf works by comparing object pointer addresses, which (because they are actually different wrapper objects) doesn't give you the expected results. He acknowledges that this behavior is controversial, and says that there is a collector entry to change it so that you would get the answer you expect in the above. (We just need to get to it). Acquisition Module Functions ============================ In addition to using acquisition attributes and methods directly on objects you can use similar functions defined in the ``Acquisition`` module. These functions have the advantage that you don't need to check to make sure that the object has the method or attribute before calling it. ``aq_acquire(object, name [, filter, extra, explicit, default, containment])`` Acquires an object with the given name. This function can be used to explictly acquire when using explicit acquisition and to acquire names that wouldn't normally be acquired. The function accepts a number of optional arguments: ``filter`` A callable filter object that is used to decide if an object should be acquired. The filter is called with five arguments: * The object that the aq_acquire method was called on, * The object where an object was found, * The name of the object, as passed to aq_acquire, * The object found, and * The extra argument passed to aq_acquire. If the filter returns a true object that the object found is returned, otherwise, the acquisition search continues. ``extra`` Extra data to be passed as the last argument to the filter. ``explicit`` A flag (boolean value) indicating whether explicit acquisition should be used. The default value is true. If the flag is true, then acquisition will proceed regardless of whether wrappers encountered in the search of the acquisition hierarchy are explicit or implicit wrappers. If the flag is false, then parents of explicit wrappers are not searched. This argument is useful if you want to apply a filter without overriding explicit wrappers. ``default`` A default value to return if no value can be acquired. ``containment`` A flag indicating whether the search should be limited to the containment hierarchy. In addition, arguments can be provided as keywords. ``aq_base(object)`` Return the object with all wrapping removed. ``aq_chain(object [, containment])`` Return a list containing the object and it's acquisition parents. The optional argument, containment, controls whether the containment or access hierarchy is used. ``aq_get(object, name [, default, containment])`` Acquire an attribute, name. A default value can be provided, as can a flag that limits search to the containment hierarchy. ``aq_inner(object)`` Return the object with all but the innermost layer of wrapping removed. ``aq_parent(object)`` Return the acquisition parent of the object or None if the object is unwrapped. ``aq_self(object)`` Return the object with one layer of wrapping removed, unless the object is unwrapped, in which case the object is returned. In most cases it is more convenient to use these module functions instead of the acquisition attributes and methods directly. Acquisition and Methods ======================= Python methods of objects that support acquisition can use acquired attributes. When a Python method is called on an object that is wrapped by an acquisition wrapper, the wrapper is passed to the method as the first argument. This rule also applies to user-defined method types and to C methods defined in pure mix-in classes. Unfortunately, C methods defined in extension base classes that define their own data structures, cannot use aquired attributes at this time. This is because wrapper objects do not conform to the data structures expected by these methods. In practice, you will seldom find this a problem. Conclusion ========== Acquisition provides a powerful way to dynamically share information between objects. Zope 2 uses acquisition for a number of its key features including security, object publishing, and DTML variable lookup. Acquisition also provides an elegant solution to the problem of circular references for many classes of problems. While acquisition is powerful, you should take care when using acquisition in your applications. The details can get complex, especially with the differences between acquiring from context and acquiring from containment. Changelog ========= 2.13.8 (2011-06-11) ------------------- - Fixed a segfault on 64bit platforms when providing the `explicit` argument to the aq_acquire method of an Acquisition wrapper. Thx to LP #675064 for the hint to the solution. The code passed an int instead of a pointer into a function. 2.13.7 (2011-03-02) ------------------- - Fixed bug: When an object did not implement ``__unicode__``, calling ``unicode(wrapped)`` was calling ``__str__`` with an unwrapped ``self``. 2.13.6 (2011-02-19) ------------------- - Add ``aq_explicit`` to ``IAcquisitionWrapper``. - Fixed bug: ``unicode(wrapped)`` was not calling a ``__unicode__`` method on wrapped objects. 2.13.5 (2010-09-29) ------------------- - Fixed unit tests that failed on 64bit Python on Windows machines. 2.13.4 (2010-08-31) ------------------- - LP 623665: Fixed typo in Acquisition.h. 2.13.3 (2010-04-19) ------------------- - Use the doctest module from the standard library and no longer depend on zope.testing. 2.13.2 (2010-04-04) ------------------- - Give both wrapper classes a ``__getnewargs__`` method, which causes the ZODB optimization to fail and create persistent references using the ``_p_oid`` alone. This happens to be the persistent oid of the wrapped object. This lets these objects to be persisted correctly, even though they are passed to the ZODB in a wrapped state. - Added failing tests for http://dev.plone.org/plone/ticket/10318. This shows an edge-case where AQ wrappers can be pickled using the specific combination of cPickle, pickle protocol one and a custom Pickler class with an ``inst_persistent_id`` hook. Unfortunately this is the exact combination used by ZODB3. 2.13.1 (2010-02-23) ------------------- - Update to include ExtensionClass 2.13.0. - Fix the ``tp_name`` of the ImplicitAcquisitionWrapper and ExplicitAcquisitionWrapper to match their Python visible names and thus have a correct ``__name__``. - Expand the ``tp_name`` of our extension types to hold the fully qualified name. This ensures classes have their ``__module__`` set correctly. 2.13.0 (2010-02-14) ------------------- - Added support for method cache in Acquisition. Patch contributed by Yoshinori K. Okuji. See https://bugs.launchpad.net/zope2/+bug/486182. 2.12.4 (2009-10-29) ------------------- - Fix iteration proxying to pass `self` acquisition-wrapped into both `__iter__` as well as `__getitem__` (this fixes https://bugs.launchpad.net/zope2/+bug/360761). - Add tests for the __getslice__ proxying, including open-ended slicing. 2.12.3 (2009-08-08) ------------------- - More 64-bit fixes in Py_BuildValue calls. - More 64-bit issues fixed: Use correct integer size for slice operations. 2.12.2 (2009-08-02) ------------------- - Fixed 64-bit compatibility issues for Python 2.5.x / 2.6.x. See http://www.python.org/dev/peps/pep-0353/ for details. 2.12.1 (2009-04-15) ------------------- - Update for iteration proxying: The proxy for `__iter__` must not rely on the object to have an `__iter__` itself, but also support fall-back iteration via `__getitem__` (this fixes https://bugs.launchpad.net/zope2/+bug/360761). 2.12 (2009-01-25) ----------------- - Release as separate package.

To use acquisition your classes must inherit from an acquisition base class. For example:: >>> import ExtensionClass, Acquisition >>> class C(ExtensionClass.Base): ... color='red' >>> class A(Acquisition.Implicit): ... def report(self): ... print self.color ... >>> a = A() >>> c = C() >>> c.a = a >>> c.a.report() red >>> d = C() >>> d.color = 'green' >>> d.a = a >>> d.a.report() green >>> a.report() # raises an attribute error Traceback (most recent call last): ... AttributeError: color The class ``A`` inherits acquisition behavior from ``Acquisition.Implicit``. The object, ``a``, "has" the color of objects ``c`` and d when it is accessed through them, but it has no color by itself. The object ``a`` obtains attributes from its environment, where its environment is defined by the access path used to reach ``a``. Acquisition Wrappers ==================== When an object that supports acquisition is accessed through an extension class instance, a special object, called an acquisition wrapper, is returned. In the example above, the expression ``c.a`` returns an acquisition wrapper that contains references to both ``c`` and ``a``. It is this wrapper that performs attribute lookup in ``c`` when an attribute cannot be found in ``a``. Acquisition wrappers provide access to the wrapped objects through the attributes ``aq_parent``, ``aq_self``, ``aq_base``. Continue the example from above:: >>> c.a.aq_parent is c True >>> c.a.aq_self is a True Explicit and Implicit Acquisition ================================= Two styles of acquisition are supported: implicit and explicit acquisition. Implicit acquisition -------------------- Implicit acquisition is so named because it searches for attributes from the environment automatically whenever an attribute cannot be obtained directly from an object or through inheritance. An attribute can be implicitly acquired if its name does not begin with an underscore. To support implicit acquisition, your class should inherit from the mix-in class ``Acquisition.Implicit``. Explicit Acquisition -------------------- When explicit acquisition is used, attributes are not automatically obtained from the environment. Instead, the method aq_acquire must be used. For example:: >>> print c.a.aq_acquire('color') red To support explicit acquisition, your class should inherit from the mix-in class ``Acquisition.Explicit``. Controlling Acquisition ----------------------- A class (or instance) can provide attribute by attribute control over acquisition. Your should subclass from ``Acquisition.Explicit``, and set all attributes that should be acquired to the special value ``Acquisition.Acquired``. Setting an attribute to this value also allows inherited attributes to be overridden with acquired ones. For example:: >>> class C(Acquisition.Explicit): ... id=1 ... secret=2 ... color=Acquisition.Acquired ... __roles__=Acquisition.Acquired The only attributes that are automatically acquired from containing objects are color, and ``__roles__``. Note that the ``__roles__`` attribute is acquired even though its name begins with an underscore. In fact, the special ``Acquisition.Acquired`` value can be used in ``Acquisition.Implicit`` objects to implicitly acquire selected objects that smell like private objects. Sometimes, you want to dynamically make an implicitly acquiring object acquire explicitly. You can do this by getting the object's aq_explicit attribute. This attribute provides the object with an explicit wrapper that replaces the original implicit wrapper. Filtered Acquisition ==================== The acquisition method, ``aq_acquire``, accepts two optional arguments. The first of the additional arguments is a "filtering" function that is used when considering whether to acquire an object. The second of the additional arguments is an object that is passed as extra data when calling the filtering function and which defaults to ``None``. The filter function is called with five arguments: * The object that the aq_acquire method was called on, * The object where an object was found, * The name of the object, as passed to aq_acquire, * The object found, and * The extra data passed to aq_acquire. If the filter returns a true object that the object found is returned, otherwise, the acquisition search continues. Here's an example:: >>> from Acquisition import Explicit >>> class HandyForTesting: ... def __init__(self, name): ... self.name = name ... def __str__(self): ... return "%s(%s)" % (self.name, self.__class__.__name__) ... __repr__=__str__ ... >>> class E(Explicit, HandyForTesting): pass ... >>> class Nice(HandyForTesting): ... isNice= 1 ... def __str__(self): ... return HandyForTesting.__str__(self)+' and I am nice!' ... __repr__=__str__ ... >>> a = E('a') >>> a.b = E('b') >>> a.b.c = E('c') >>> a.p = Nice('spam') >>> a.b.p = E('p') >>> def find_nice(self, ancestor, name, object, extra): ... return hasattr(object,'isNice') and object.isNice >>> print a.b.c.aq_acquire('p', find_nice) spam(Nice) and I am nice! The filtered acquisition in the last line skips over the first attribute it finds with the name ``p``, because the attribute doesn't satisfy the condition given in the filter. Filtered acquisition is rarely used in Zope. Acquiring from Context ====================== Normally acquisition allows objects to acquire data from their containers. However an object can acquire from objects that aren't its containers. Most of the examples we've seen so far show establishing of an acquisition context using getattr semantics. For example, ``a.b`` is a reference to ``b`` in the context of ``a``. You can also manually set acquisition context using the ``__of__`` method. For example:: >>> from Acquisition import Implicit >>> class C(Implicit): pass ... >>> a = C() >>> b = C() >>> a.color = "red" >>> print b.__of__(a).color red In this case, ``a`` does not contain ``b``, but it is put in ``b``'s context using the ``__of__`` method. Here's another subtler example that shows how you can construct an acquisition context that includes non-container objects:: >>> from Acquisition import Implicit >>> class C(Implicit): ... def __init__(self, name): ... self.name = name >>> a = C("a") >>> a.b = C("b") >>> a.b.color = "red" >>> a.x = C("x") >>> print a.b.x.color red Even though ``b`` does not contain ``x``, ``x`` can acquire the color attribute from ``b``. This works because in this case, ``x`` is accessed in the context of ``b`` even though it is not contained by ``b``. Here acquisition context is defined by the objects used to access another object. Containment Before Context ========================== If in the example above suppose both a and b have an color attribute:: >>> a = C("a") >>> a.color = "green" >>> a.b = C("b") >>> a.b.color = "red" >>> a.x = C("x") >>> print a.b.x.color green Why does ``a.b.x.color`` acquire color from ``a`` and not from ``b``? The answer is that an object acquires from its containers before non-containers in its context. To see why consider this example in terms of expressions using the ``__of__`` method:: a.x -> x.__of__(a) a.b -> b.__of__(a) a.b.x -> x.__of__(a).__of__(b.__of__(a)) Keep in mind that attribute lookup in a wrapper is done by trying to look up the attribute in the wrapped object first and then in the parent object. So in the expressions above proceeds from left to right. The upshot of these rules is that attributes are looked up by containment before context. This rule holds true also for more complex examples. For example, ``a.b.c.d.e.f.g.attribute`` would search for attribute in ``g`` and all its containers first. (Containers are searched in order from the innermost parent to the outermost container.) If the attribute is not found in ``g`` or any of its containers, then the search moves to ``f`` and all its containers, and so on. Additional Attributes and Methods ================================= You can use the special method ``aq_inner`` to access an object wrapped only by containment. So in the example above, ``a.b.x.aq_inner`` is equivalent to ``a.x``. You can find out the acquisition context of an object using the aq_chain method like so: >>> [obj.name for obj in a.b.x.aq_chain] ['x', 'b', 'a'] You can find out if an object is in the containment context of another object using the ``aq_inContextOf`` method. For example: >>> a.b.aq_inContextOf(a) 1 .. Note: as of this writing the aq_inContextOf examples don't work the way they should be working. According to Jim, this is because aq_inContextOf works by comparing object pointer addresses, which (because they are actually different wrapper objects) doesn't give you the expected results. He acknowledges that this behavior is controversial, and says that there is a collector entry to change it so that you would get the answer you expect in the above. (We just need to get to it). Acquisition Module Functions ============================ In addition to using acquisition attributes and methods directly on objects you can use similar functions defined in the ``Acquisition`` module. These functions have the advantage that you don't need to check to make sure that the object has the method or attribute before calling it. ``aq_acquire(object, name [, filter, extra, explicit, default, containment])`` Acquires an object with the given name. This function can be used to explictly acquire when using explicit acquisition and to acquire names that wouldn't normally be acquired. The function accepts a number of optional arguments: ``filter`` A callable filter object that is used to decide if an object should be acquired. The filter is called with five arguments: * The object that the aq_acquire method was called on, * The object where an object was found, * The name of the object, as passed to aq_acquire, * The object found, and * The extra argument passed to aq_acquire. If the filter returns a true object that the object found is returned, otherwise, the acquisition search continues. ``extra`` Extra data to be passed as the last argument to the filter. ``explicit`` A flag (boolean value) indicating whether explicit acquisition should be used. The default value is true. If the flag is true, then acquisition will proceed regardless of whether wrappers encountered in the search of the acquisition hierarchy are explicit or implicit wrappers. If the flag is false, then parents of explicit wrappers are not searched. This argument is useful if you want to apply a filter without overriding explicit wrappers. ``default`` A default value to return if no value can be acquired. ``containment`` A flag indicating whether the search should be limited to the containment hierarchy. In addition, arguments can be provided as keywords. ``aq_base(object)`` Return the object with all wrapping removed. ``aq_chain(object [, containment])`` Return a list containing the object and it's acquisition parents. The optional argument, containment, controls whether the containment or access hierarchy is used. ``aq_get(object, name [, default, containment])`` Acquire an attribute, name. A default value can be provided, as can a flag that limits search to the containment hierarchy. ``aq_inner(object)`` Return the object with all but the innermost layer of wrapping removed. ``aq_parent(object)`` Return the acquisition parent of the object or None if the object is unwrapped. ``aq_self(object)`` Return the object with one layer of wrapping removed, unless the object is unwrapped, in which case the object is returned. In most cases it is more convenient to use these module functions instead of the acquisition attributes and methods directly.

When a Python method is called on an object that is wrapped by an acquisition wrapper, the wrapper is passed to the method as the first argument. This rule also applies to user-defined method types and to C methods defined in pure mix-in classes. Unfortunately, C methods defined in extension base classes that define their own data structures, cannot use aquired attributes at this time. This is because wrapper objects do not conform to the data structures expected by these methods. In practice, you will seldom find this a problem.

It is similar to inheritence, except that, rather than traversing an inheritence hierarchy to obtain attributes, a containment hierarchy is traversed. The "ExtensionClass":ExtensionClass.html. release includes mix-in extension base classes that can be used to add acquisition as a feature to extension subclasses. These mix-in classes use the context-wrapping feature of ExtensionClasses to implement acquisition. Consider the following example:: >>> import ExtensionClass, Acquisition >>> class C(ExtensionClass.Base): ... color='red' >>> class A(Acquisition.Implicit): ... def report(self): ... print self.color >>> a = A() >>> c = C() >>> c.a = a >>> c.a.report() red >>> d = C() >>> d.color = 'green' >>> d.a = a >>> d.a.report() green >>> a.report() # raises an attribute error Traceback (most recent call last): ... AttributeError: color The class 'A' inherits acquisition behavior from 'Acquisition.Implicit'. The object, 'a', "has" the color of objects 'c' and 'd' when it is accessed through them, but it has no color by itself. The object 'a' obtains attributes from it's environment, where it's environment is defined by the access path used to reach 'a'. Acquisition wrappers When an object that supports acquisition is accessed through an extension class instance, a special object, called an acquisition wrapper, is returned. In the example above, the expression 'c.a' returns an acquisition wrapper that contains references to both 'c' and 'a'. It is this wrapper that performs attribute lookup in 'c' when an attribute cannot be found in 'a'. Aquisition wrappers provide access to the wrapped objects through the attributes 'aq_parent', 'aq_self', 'aq_base'. In the example above, the expressions:: >>> c.a.aq_parent is c 1 and:: >>> c.a.aq_self is a 1 both evaluate to true, but the expression:: >>> c.a is a 0 evaluates to false, because the expression 'c.a' evaluates to an acquisition wrapper around 'c' and 'a', not 'a' itself. The attribute 'aq_base' is similar to 'aq_self'. Wrappers may be nested and 'aq_self' may be a wrapped object. The 'aq_base' attribute is the underlying object with all wrappers removed. Acquisition Control Two styles of acquisition are supported in the current ExtensionClass release, implicit and explicit aquisition. Implicit acquisition Implicit acquisition is so named because it searches for attributes from the environment automatically whenever an attribute cannot be obtained directly from an object or through inheritence. An attribute may be implicitly acquired if it's name does not begin with an underscore, '_'. To support implicit acquisition, an object should inherit from the mix-in class 'Acquisition.Implicit'. Explicit Acquisition When explicit acquisition is used, attributes are not automatically obtained from the environment. Instead, the method 'aq_aquire' must be used, as in:: print c.a.aq_acquire('color') To support explicit acquisition, an object should inherit from the mix-in class 'Acquisition.Explicit'. Controlled Acquisition A class (or instance) can provide attribute by attribute control over acquisition. This is done by: - subclassing from 'Acquisition.Explicit', and - setting all attributes that should be acquired to the special value: 'Acquisition.Acquired'. Setting an attribute to this value also allows inherited attributes to be overridden with acquired ones. For example, in:: >>> class E(Acquisition.Explicit): ... id = 1 ... secret = 2 ... color = Acquisition.Acquired ... __roles__ = Acquisition.Acquired The *only* attributes that are automatically acquired from containing objects are 'color', and '__roles__'. >>> c = C() >>> c.foo = 'foo' >>> c.e = E() >>> c.e.color 'red' >>> c.e.foo Traceback (most recent call last): ... AttributeError: foo Note also that the '__roles__' attribute is acquired even though it's name begins with an underscore: >>> c.__roles__ = 'Manager', 'Member' >>> c.e.__roles__ ('Manager', 'Member') In fact, the special 'Acquisition.Acquired' value can be used in 'Acquisition.Implicit' objects to implicitly acquire selected objects that smell like private objects. >>> class I(Acquisition.Implicit): ... __roles__ = Acquisition.Acquired >>> c.x = C() >>> c.x.__roles__ Traceback (most recent call last): ... AttributeError: __roles__ >>> c.x = I() >>> c.x.__roles__ ('Manager', 'Member') Filtered Acquisition The acquisition method, 'aq_acquire', accepts two optional arguments. The first of the additional arguments is a "filtering" function that is used when considering whether to acquire an object. The second of the additional arguments is an object that is passed as extra data when calling the filtering function and which defaults to 'None'. The filter function is called with five arguments: - The object that the 'aq_acquire' method was called on, - The object where an object was found, - The name of the object, as passed to 'aq_acquire', - The object found, and - The extra data passed to 'aq_acquire'. If the filter returns a true object that the object found is returned, otherwise, the acquisition search continues. For example, in:: >>> from Acquisition import Explicit >>> class HandyForTesting: ... def __init__(self, name): self.name=name ... def __str__(self): ... return "%s(%s)" % (self.name, self.__class__.__name__) ... __repr__=__str__ >>> class E(Explicit, HandyForTesting): ... pass >>> class Nice(HandyForTesting): ... isNice=1 ... def __str__(self): ... return HandyForTesting.__str__(self)+' and I am nice!' ... __repr__=__str__ >>> a = E('a') >>> a.b = E('b') >>> a.b.c = E('c') >>> a.p = Nice('spam') >>> a.b.p = E('p') >>> def find_nice(self, ancestor, name, object, extra): ... return hasattr(object,'isNice') and object.isNice >>> print a.b.c.aq_acquire('p', find_nice) spam(Nice) and I am nice! The filtered acquisition in the last line skips over the first attribute it finds with the name 'p', because the attribute doesn't satisfy the condition given in the filter. Acquisition and methods Python methods of objects that support acquisition can use acquired attributes as in the 'report' method of the first example above. When a Python method is called on an object that is wrapped by an acquisition wrapper, the wrapper is passed to the method as the first argument. This rule also applies to user-defined method types and to C methods defined in pure mix-in classes. Unfortunately, C methods defined in extension base classes that define their own data structures, cannot use aquired attributes at this time. This is because wrapper objects do not conform to the data structures expected by these methods. Acquiring Acquiring objects Consider the following example:: >>> from Acquisition import Implicit >>> class C(Implicit): ... def __init__(self, name): self.name=name ... def __str__(self): ... return "%s(%s)" % (self.name, self.__class__.__name__) ... __repr__=__str__ >>> a = C("a") >>> a.b = C("b") >>> a.b.pref = "spam" >>> a.b.c = C("c") >>> a.b.c.color = "red" >>> a.b.c.pref = "eggs" >>> a.x = C("x") >>> o = a.b.c.x The expression 'o.color' might be expected to return '"red"'. In earlier versions of ExtensionClass, however, this expression failed. Acquired acquiring objects did not acquire from the environment they were accessed in, because objects were only wrapped when they were first found, and were not rewrapped as they were passed down the acquisition tree. In the current release of ExtensionClass, the expression "o.color" does indeed return '"red"'. >>> o.color 'red' When searching for an attribute in 'o', objects are searched in the order 'x', 'a', 'b', 'c'. So, for example, the expression, 'o.pref' returns '"spam"', not '"eggs"':: >>> o.pref 'spam' In earlier releases of ExtensionClass, the attempt to get the 'pref' attribute from 'o' would have failed. If desired, the current rules for looking up attributes in complex expressions can best be understood through repeated application of the '__of__' method: 'a.x' -- 'x.__of__(a)' 'a.b' -- 'b.__of__(a)' 'a.b.x' -- 'x.__of__(a).__of__(b.__of__(a))' 'a.b.c' -- 'c.__of__(b.__of__(a))' 'a.b.c.x' -- 'x.__of__(a).__of__(b.__of__(a)).__of__(c.__of__(b.__of__(a)))' and by keeping in mind that attribute lookup in a wrapper is done by trying to lookup the attribute in the wrapped object first and then in the parent object. In the expressions above involving the '__of__' method, lookup proceeds from left to right. Note that heuristics are used to avoid most of the repeated lookups. For example, in the expression: 'a.b.c.x.foo', the object 'a' is searched no more than once, even though it is wrapped three times. ..

There are three issues we need to deal with: File system representation Every object is either a directory or a file. Properties There are two kinds of proprties: - Data properties Data properties are handled directly by the object implementation. - Meta-data properties Meta data properties are handled via annotations. Completeness We must have a complete lossless data representation for file-system synchronization. This is achieved through serialization of: - All annotations (not just properties), and - Extra data. Strategies for common access mechanisms: FTP - For getting directory info (statish) information: - Use Zope DublinCore to get modification times - Show as readable if we can access a read method. - Show as writable if we can access a write method. FTP and WebDAV - Treat as a directory if there is an adapter to `IReadDirectory`. Treat as a file otherwise. - For creating objects: - Directories: Look for an `IDirectoryFactory` adapter. - Files First lookj for a `IFileFactory` adapter with a name that is the same as the extention (e.g. ".pt"). Then look for an unnamed `IFileFactory` adapter. File-system synchronization Because this must be lossless, we will use class-based adapters for this, but we want to make it as easy as possible to use other adapters as well. For reading, there must be a class adapter to `IReadSync`. We will then apply rules similar to those above.

Every folder: >>> from zope.site import folder >>> myfolder = folder.rootFolder() has the potential to become a site: >>> from zope.component.interfaces import ISite, IPossibleSite >>> IPossibleSite.providedBy(myfolder) True but is not yet one: >>> ISite.providedBy(myfolder) False If you would like your custom content component to be able to become a site, you can use the `SiteManagerContainer` mix-in class: >>> from zope import site >>> class MyContentComponent(site.SiteManagerContainer): ... pass >>> myContent = MyContentComponent() >>> IPossibleSite.providedBy(myContent) True >>> ISite.providedBy(myContent) False To convert a possible site to a real site, we have to provide a site manager: >>> sm = site.LocalSiteManager(myfolder) >>> myfolder.setSiteManager(sm) >>> ISite.providedBy(myfolder) True >>> myfolder.getSiteManager() is sm True Note that an event is generated when a local site manager is created: >>> from zope.component.eventtesting import getEvents >>> from zope.site.interfaces import INewLocalSite >>> [event] = getEvents(INewLocalSite) >>> event.manager is sm True If one tries to set a bogus site manager, a `ValueError` will be raised: >>> myfolder2 = folder.Folder() >>> myfolder2.setSiteManager(object) Traceback (most recent call last): ... ValueError: setSiteManager requires an IComponentLookup If the possible site has been changed to a site already, a `TypeError` is raised when one attempts to add a new site manager: >>> myfolder.setSiteManager(site.LocalSiteManager(myfolder)) Traceback (most recent call last): ... TypeError: Already a site There is also an adapter you can use to get the next site manager from any location: >>> myfolder['mysubfolder'] = folder.Folder() >>> import zope.component >>> zope.component.interfaces.IComponentLookup(myfolder['mysubfolder']) is sm True If the location passed is a site, the site manager of that site is returned: >>> zope.component.interfaces.IComponentLookup(myfolder) is sm True Using the Site Manager ---------------------- A site manager contains several *site management folders*, which are used to logically organize the software. When a site manager is initialized, a default site management folder is created: >>> sm = myfolder.getSiteManager() >>> default = sm['default'] >>> default.__class__ However, you can tell not to create the default site manager folder on LocalSiteManager creation: >>> nodefault = site.LocalSiteManager(myfolder, default_folder=False) >>> 'default' in nodefault False Also, note that when creating LocalSiteManager, its __parent__ is set to site that was passed to constructor and the __name__ is set to ++etc++site. >>> nodefault.__parent__ is myfolder True >>> nodefault.__name__ == '++etc++site' True You can easily create a new site management folder: >>> sm['mySMF'] = site.SiteManagementFolder() >>> sm['mySMF'].__class__ Once you have your site management folder -- let's use the default one -- we can register some components. Let's start with a utility: >>> import zope.interface >>> class IMyUtility(zope.interface.Interface): ... pass >>> import persistent >>> from zope.container.contained import Contained >>> class MyUtility(persistent.Persistent, Contained): ... zope.interface.implements(IMyUtility) ... def __init__(self, title): ... self.title = title ... def __repr__(self): ... return "%s('%s')" %(self.__class__.__name__, self.title) Now we can create an instance of our utility and put it in the site management folder and register it: >>> myutil = MyUtility('My custom utility') >>> default['myutil'] = myutil >>> sm.registerUtility(myutil, IMyUtility, 'u1') Now we can ask the site manager for the utility: >>> sm.queryUtility(IMyUtility, 'u1') MyUtility('My custom utility') Of course, the local site manager has also access to the global component registrations: >>> gutil = MyUtility('Global Utility') >>> from zope.component import getGlobalSiteManager >>> gsm = getGlobalSiteManager() >>> gsm.registerUtility(gutil, IMyUtility, 'gutil') >>> sm.queryUtility(IMyUtility, 'gutil') MyUtility('Global Utility') Next let's see whether we can also successfully register an adapter as well. Here the adapter will provide the size of a file: >>> class IFile(zope.interface.Interface): ... pass >>> class ISized(zope.interface.Interface): ... pass >>> class File(object): ... zope.interface.implements(IFile) >>> class FileSize(object): ... zope.interface.implements(ISized) ... def __init__(self, context): ... self.context = context Now that we have the adapter we need to register it: >>> sm.registerAdapter(FileSize, [IFile]) Finally, we can get the adapter for a file: >>> file = File() >>> size = sm.queryAdapter(file, ISized, name='') >>> size.__class__ >>> size.context is file True By the way, once you set a site >>> from zope.component import hooks >>> hooks.setSite(myfolder) you can simply use the zope.component's `getSiteManager()` method to get the nearest site manager: >>> from zope.component import getSiteManager >>> getSiteManager() is sm True This also means that you can simply use zope.component to look up your utility >>> from zope.component import getUtility >>> getUtility(IMyUtility, 'gutil') MyUtility('Global Utility') or the adapter via the interface's `__call__` method: >>> size = ISized(file) >>> size.__class__ >>> size.context is file True Multiple Sites -------------- Until now we have only dealt with one local and the global site. But things really become interesting, once we have multiple sites. We can override other local configuration. This behaviour uses the notion of location, therefore we need to configure the zope.location package first: >>> import zope.configuration.xmlconfig >>> _ = zope.configuration.xmlconfig.string(""" ... ... ... ... ... """) Let's now create a new folder called `folder11`, add it to `myfolder` and make it a site: >>> myfolder11 = folder.Folder() >>> myfolder['myfolder11'] = myfolder11 >>> myfolder11.setSiteManager(site.LocalSiteManager(myfolder11)) >>> sm11 = myfolder11.getSiteManager() If we ask the second site manager for its next, we get >>> sm11.__bases__ == (sm, ) True and the first site manager should have the folling sub manager: >>> sm.subs == (sm11,) True If we now register a second utility with the same name and interface with the new site manager folder, >>> default11 = sm11['default'] >>> myutil11 = MyUtility('Utility, uno & uno') >>> default11['myutil'] = myutil11 >>> sm11.registerUtility(myutil11, IMyUtility, 'u1') then it will will be available in the second site manager >>> sm11.queryUtility(IMyUtility, 'u1') MyUtility('Utility, uno & uno') but not in the first one: >>> sm.queryUtility(IMyUtility, 'u1') MyUtility('My custom utility') It is also interesting to look at the use cases of moving and copying a site. To do that we create a second root folder and make it a site, so that site hierarchy is as follows: :: _____ global site _____ / \ myfolder1 myfolder2 | myfolder11 >>> myfolder2 = folder.rootFolder() >>> myfolder2.setSiteManager(site.LocalSiteManager(myfolder2)) Before we can move or copy sites, we need to register two event subscribers that manage the wiring of site managers after moving or copying: >>> from zope import container >>> gsm.registerHandler( ... site.changeSiteConfigurationAfterMove, ... (ISite, container.interfaces.IObjectMovedEvent), ... ) We only have to register one event listener, since the copy action causes an `IObjectAddedEvent` to be created, which is just a special type of `IObjectMovedEvent`. First, make sure that everything is setup correctly in the first place: >>> myfolder11.getSiteManager().__bases__ == (myfolder.getSiteManager(), ) True >>> myfolder.getSiteManager().subs[0] is myfolder11.getSiteManager() True >>> myfolder2.getSiteManager().subs () Let's now move `myfolder11` from `myfolder` to `myfolder2`: >>> myfolder2['myfolder21'] = myfolder11 >>> del myfolder['myfolder11'] Now the next site manager for `myfolder11`'s site manager should have changed: >>> myfolder21 = myfolder11 >>> myfolder21.getSiteManager().__bases__ == (myfolder2.getSiteManager(), ) True >>> myfolder2.getSiteManager().subs[0] is myfolder21.getSiteManager() True >>> myfolder.getSiteManager().subs () Make sure that our interfaces and classes are picklable: >>> import sys >>> sys.modules['zope.site.tests'].IMyUtility = IMyUtility >>> IMyUtility.__module__ = 'zope.site.tests' >>> sys.modules['zope.site.tests'].MyUtility = MyUtility >>> MyUtility.__module__ = 'zope.site.tests' >>> from pickle import dumps, loads >>> data = dumps(myfolder2['myfolder21']) >>> myfolder['myfolder11'] = loads(data) >>> myfolder11 = myfolder['myfolder11'] >>> myfolder11.getSiteManager().__bases__ == (myfolder.getSiteManager(), ) True >>> myfolder.getSiteManager().subs[0] is myfolder11.getSiteManager() True >>> myfolder2.getSiteManager().subs[0] is myfolder21.getSiteManager() True Finally, let's check that everything works fine when our folder is moved to the folder that doesn't contain any site manager. Our folder's sitemanager's bases should be set to global site manager. >>> myfolder11.getSiteManager().__bases__ == (myfolder.getSiteManager(), ) True >>> nosm = folder.Folder() >>> nosm['root'] = myfolder11 >>> myfolder11.getSiteManager().__bases__ == (gsm, ) True ======= CHANGES ======= 3.9.2 (2010-09-25) ------------------ - Added not declared, but needed test dependency on `zope.testing`. 3.9.1 (2010-04-30) ------------------ - Removed use of 'zope.testing.doctest' in favor of stdlib's 'doctest. - Removed use of 'zope.testing.doctestunit' in favor of stdlib's 'doctest. 3.9.0 (2009-12-29) ------------------ - Avoid a test dependency on zope.copypastemove by testing the correct persistent behavior of a site manager using the normal pickle module. 3.8.0 (2009-12-15) ------------------ - Removed functional testing setup and dependency on zope.app.testing. 3.7.1 (2009-11-18) ------------------ - Moved the zope.site.hooks functionality to zope.component.hooks as it isn't actually dealing with zope.site's concept of a site. - Import ISite and IPossibleSite from zope.component after they were moved there from zope.location. 3.7.0 (2009-09-29) ------------------ - Cleaned up the undeclared dependency on zope.app.publication by moving the two relevant subscriber registrations and their tests to that package. - Dropped the dependency on zope.traversing which was only used to access zope.location functionality. Configure zope.location for some tests. - Demoted zope.configuration to a testing dependency. 3.6.4 (2009-09-01) ------------------ - Set __parent__ and __name__ in the LocalSiteManager's constructor after calling constructor of its superclasses, so __name__ doesn't get overwritten with empty string by the Components constructor. - Don't set __parent__ and __name__ attributes of site manager in SiteManagerContainer's ``setSiteManager`` method, as they're already set for LocalSiteManager. Other site manager implementations are not required to have those attributes at all, so we're not adding them anymore. 3.6.3 (2009-07-27) ------------------ - Propagate an ObjectRemovedEvent to the SiteManager upon removal of a SiteManagerContainer. 3.6.2 (2009-07-24) ------------------ - Fixed tests to pass with latest packages. - Removed failing test of persistent interfaces, since it did not test anything in this package and used the deprecated ``zodbcode`` module. - Fix NameError when calling ``zope.site.testing.siteSetUp(site=True)``. - The ``getNextUtility`` and ``queryNextUtility`` functions was moved to ``zope.component``. While backward-compatibility imports are provided, it's strongly recommended to update your imports. 3.6.1 (2009-02-28) ------------------ - Import symbols moved from zope.traversing to zope.location from the new location. - Don't fail when changing component registry bases while moving ISite object to non-ISite object. - Allow specify whether to create 'default' SiteManagementFolder on initializing LocalSiteManager. Use the ``default_folder`` argument. - Add a containment constraint to the SiteManagementFolder that makes it only available to be contained in ILocalSiteManagers and other ISiteManagementFolders. - Change package's mailing list address to zope-dev at zope.org, as zope3-dev at zope.org is now retired. - Remove old unused code. Update package description. 3.6.0 (2009-01-31) ------------------ - Use zope.container instead of zope.app.container. 3.5.1 (2009-01-27) ------------------ - Extracted from zope.app.component (trunk, 3.5.1 under development) as part of an effort to clean up dependencies between Zope packages.

Configure zope.location for some tests. - Demoted zope.configuration to a testing dependency. 3.6.4 (2009-09-01) ------------------ - Set __parent__ and __name__ in the LocalSiteManager's constructor after calling constructor of its superclasses, so __name__ doesn't get overwritten with empty string by the Components constructor. - Don't set __parent__ and __name__ attributes of site manager in SiteManagerContainer's ``setSiteManager`` method, as they're already set for LocalSiteManager. Other site manager implementations are not required to have those attributes at all, so we're not adding them anymore. 3.6.3 (2009-07-27) ------------------ - Propagate an ObjectRemovedEvent to the SiteManager upon removal of a SiteManagerContainer. 3.6.2 (2009-07-24) ------------------ - Fixed tests to pass with latest packages. - Removed failing test of persistent interfaces, since it did not test anything in this package and used the deprecated ``zodbcode`` module. - Fix NameError when calling ``zope.site.testing.siteSetUp(site=True)``. - The ``getNextUtility`` and ``queryNextUtility`` functions was moved to ``zope.component``. While backward-compatibility imports are provided, it's strongly recommended to update your imports. 3.6.1 (2009-02-28) ------------------ - Import symbols moved from zope.traversing to zope.location from the new location. - Don't fail when changing component registry bases while moving ISite object to non-ISite object. - Allow specify whether to create 'default' SiteManagementFolder on initializing LocalSiteManager. Use the ``default_folder`` argument. - Add a containment constraint to the SiteManagementFolder that makes it only available to be contained in ILocalSiteManagers and other ISiteManagementFolders. - Change package's mailing list address to zope-dev at zope.org, as zope3-dev at zope.org is now retired. - Remove old unused code.

Creating and Accessing Sites ---------------------------- *Sites* are used to provide custom component setups for parts of your application or web site. Every folder: >>> from zope.site import folder >>> myfolder = folder.rootFolder() has the potential to become a site: >>> from zope.component.interfaces import ISite, IPossibleSite >>> IPossibleSite.providedBy(myfolder) True but is not yet one: >>> ISite.providedBy(myfolder) False If you would like your custom content component to be able to become a site, you can use the `SiteManagerContainer` mix-in class: >>> from zope import site >>> class MyContentComponent(site.SiteManagerContainer): ... pass >>> myContent = MyContentComponent() >>> IPossibleSite.providedBy(myContent) True >>> ISite.providedBy(myContent) False To convert a possible site to a real site, we have to provide a site manager: >>> sm = site.LocalSiteManager(myfolder) >>> myfolder.setSiteManager(sm) >>> ISite.providedBy(myfolder) True >>> myfolder.getSiteManager() is sm True Note that an event is generated when a local site manager is created: >>> from zope.component.eventtesting import getEvents >>> from zope.site.interfaces import INewLocalSite >>> [event] = getEvents(INewLocalSite) >>> event.manager is sm True If one tries to set a bogus site manager, a `ValueError` will be raised: >>> myfolder2 = folder.Folder() >>> myfolder2.setSiteManager(object) Traceback (most recent call last): ... ValueError: setSiteManager requires an IComponentLookup If the possible site has been changed to a site already, a `TypeError` is raised when one attempts to add a new site manager: >>> myfolder.setSiteManager(site.LocalSiteManager(myfolder)) Traceback (most recent call last): ... TypeError: Already a site There is also an adapter you can use to get the next site manager from any location: >>> myfolder['mysubfolder'] = folder.Folder() >>> import zope.component >>> zope.component.interfaces.IComponentLookup(myfolder['mysubfolder']) is sm True If the location passed is a site, the site manager of that site is returned: >>> zope.component.interfaces.IComponentLookup(myfolder) is sm True Using the Site Manager ---------------------- A site manager contains several *site management folders*, which are used to logically organize the software. When a site manager is initialized, a default site management folder is created: >>> sm = myfolder.getSiteManager() >>> default = sm['default'] >>> default.__class__ However, you can tell not to create the default site manager folder on LocalSiteManager creation: >>> nodefault = site.LocalSiteManager(myfolder, default_folder=False) >>> 'default' in nodefault False Also, note that when creating LocalSiteManager, its __parent__ is set to site that was passed to constructor and the __name__ is set to ++etc++site. >>> nodefault.__parent__ is myfolder True >>> nodefault.__name__ == '++etc++site' True You can easily create a new site management folder: >>> sm['mySMF'] = site.SiteManagementFolder() >>> sm['mySMF'].__class__ Once you have your site management folder -- let's use the default one -- we can register some components. Let's start with a utility: >>> import zope.interface >>> class IMyUtility(zope.interface.Interface): ... pass >>> import persistent >>> from zope.container.contained import Contained >>> class MyUtility(persistent.Persistent, Contained): ... zope.interface.implements(IMyUtility) ... def __init__(self, title): ... self.title = title ... def __repr__(self): ... return "%s('%s')" %(self.__class__.__name__, self.title) Now we can create an instance of our utility and put it in the site management folder and register it: >>> myutil = MyUtility('My custom utility') >>> default['myutil'] = myutil >>> sm.registerUtility(myutil, IMyUtility, 'u1') Now we can ask the site manager for the utility: >>> sm.queryUtility(IMyUtility, 'u1') MyUtility('My custom utility') Of course, the local site manager has also access to the global component registrations: >>> gutil = MyUtility('Global Utility') >>> from zope.component import getGlobalSiteManager >>> gsm = getGlobalSiteManager() >>> gsm.registerUtility(gutil, IMyUtility, 'gutil') >>> sm.queryUtility(IMyUtility, 'gutil') MyUtility('Global Utility') Next let's see whether we can also successfully register an adapter as well. Here the adapter will provide the size of a file: >>> class IFile(zope.interface.Interface): ... pass >>> class ISized(zope.interface.Interface): ... pass >>> class File(object): ... zope.interface.implements(IFile) >>> class FileSize(object): ... zope.interface.implements(ISized) ... def __init__(self, context): ... self.context = context Now that we have the adapter we need to register it: >>> sm.registerAdapter(FileSize, [IFile]) Finally, we can get the adapter for a file: >>> file = File() >>> size = sm.queryAdapter(file, ISized, name='') >>> size.__class__ >>> size.context is file True By the way, once you set a site >>> from zope.component import hooks >>> hooks.setSite(myfolder) you can simply use the zope.component's `getSiteManager()` method to get the nearest site manager: >>> from zope.component import getSiteManager >>> getSiteManager() is sm True This also means that you can simply use zope.component to look up your utility >>> from zope.component import getUtility >>> getUtility(IMyUtility, 'gutil') MyUtility('Global Utility') or the adapter via the interface's `__call__` method: >>> size = ISized(file) >>> size.__class__ >>> size.context is file True Multiple Sites -------------- Until now we have only dealt with one local and the global site. But things really become interesting, once we have multiple sites. We can override other local configuration. This behaviour uses the notion of location, therefore we need to configure the zope.location package first: >>> import zope.configuration.xmlconfig >>> _ = zope.configuration.xmlconfig.string(""" ... ... ... ... ... """) Let's now create a new folder called `folder11`, add it to `myfolder` and make it a site: >>> myfolder11 = folder.Folder() >>> myfolder['myfolder11'] = myfolder11 >>> myfolder11.setSiteManager(site.LocalSiteManager(myfolder11)) >>> sm11 = myfolder11.getSiteManager() If we ask the second site manager for its next, we get >>> sm11.__bases__ == (sm, ) True and the first site manager should have the folling sub manager: >>> sm.subs == (sm11,) True If we now register a second utility with the same name and interface with the new site manager folder, >>> default11 = sm11['default'] >>> myutil11 = MyUtility('Utility, uno & uno') >>> default11['myutil'] = myutil11 >>> sm11.registerUtility(myutil11, IMyUtility, 'u1') then it will will be available in the second site manager >>> sm11.queryUtility(IMyUtility, 'u1') MyUtility('Utility, uno & uno') but not in the first one: >>> sm.queryUtility(IMyUtility, 'u1') MyUtility('My custom utility') It is also interesting to look at the use cases of moving and copying a site. To do that we create a second root folder and make it a site, so that site hierarchy is as follows: :: _____ global site _____ / \ myfolder1 myfolder2 | myfolder11 >>> myfolder2 = folder.rootFolder() >>> myfolder2.setSiteManager(site.LocalSiteManager(myfolder2)) Before we can move or copy sites, we need to register two event subscribers that manage the wiring of site managers after moving or copying: >>> from zope import container >>> gsm.registerHandler( ... site.changeSiteConfigurationAfterMove, ... (ISite, container.interfaces.IObjectMovedEvent), ... ) We only have to register one event listener, since the copy action causes an `IObjectAddedEvent` to be created, which is just a special type of `IObjectMovedEvent`. First, make sure that everything is setup correctly in the first place: >>> myfolder11.getSiteManager().__bases__ == (myfolder.getSiteManager(), ) True >>> myfolder.getSiteManager().subs[0] is myfolder11.getSiteManager() True >>> myfolder2.getSiteManager().subs () Let's now move `myfolder11` from `myfolder` to `myfolder2`: >>> myfolder2['myfolder21'] = myfolder11 >>> del myfolder['myfolder11'] Now the next site manager for `myfolder11`'s site manager should have changed: >>> myfolder21 = myfolder11 >>> myfolder21.getSiteManager().__bases__ == (myfolder2.getSiteManager(), ) True >>> myfolder2.getSiteManager().subs[0] is myfolder21.getSiteManager() True >>> myfolder.getSiteManager().subs () Make sure that our interfaces and classes are picklable: >>> import sys >>> sys.modules['zope.site.tests'].IMyUtility = IMyUtility >>> IMyUtility.__module__ = 'zope.site.tests' >>> sys.modules['zope.site.tests'].MyUtility = MyUtility >>> MyUtility.__module__ = 'zope.site.tests' >>> from pickle import dumps, loads >>> data = dumps(myfolder2['myfolder21']) >>> myfolder['myfolder11'] = loads(data) >>> myfolder11 = myfolder['myfolder11'] >>> myfolder11.getSiteManager().__bases__ == (myfolder.getSiteManager(), ) True >>> myfolder.getSiteManager().subs[0] is myfolder11.getSiteManager() True >>> myfolder2.getSiteManager().subs[0] is myfolder21.getSiteManager() True Finally, let's check that everything works fine when our folder is moved to the folder that doesn't contain any site manager. Our folder's sitemanager's bases should be set to global site manager. >>> myfolder11.getSiteManager().__bases__ == (myfolder.getSiteManager(), ) True >>> nosm = folder.Folder() >>> nosm['root'] = myfolder11 >>> myfolder11.getSiteManager().__bases__ == (gsm, ) True zope2.13-2.13.21/source/zope.site/src/zope/site/site.py0000644000175000017500000001727512214017634021421 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

Every folder: >>> from zope.site import folder >>> myfolder = folder.rootFolder() has the potential to become a site: >>> from zope.component.interfaces import ISite, IPossibleSite >>> IPossibleSite.providedBy(myfolder) True but is not yet one: >>> ISite.providedBy(myfolder) False If you would like your custom content component to be able to become a site, you can use the `SiteManagerContainer` mix-in class: >>> from zope import site >>> class MyContentComponent(site.SiteManagerContainer): ... pass >>> myContent = MyContentComponent() >>> IPossibleSite.providedBy(myContent) True >>> ISite.providedBy(myContent) False To convert a possible site to a real site, we have to provide a site manager: >>> sm = site.LocalSiteManager(myfolder) >>> myfolder.setSiteManager(sm) >>> ISite.providedBy(myfolder) True >>> myfolder.getSiteManager() is sm True Note that an event is generated when a local site manager is created: >>> from zope.component.eventtesting import getEvents >>> from zope.site.interfaces import INewLocalSite >>> [event] = getEvents(INewLocalSite) >>> event.manager is sm True If one tries to set a bogus site manager, a `ValueError` will be raised: >>> myfolder2 = folder.Folder() >>> myfolder2.setSiteManager(object) Traceback (most recent call last): ... ValueError: setSiteManager requires an IComponentLookup If the possible site has been changed to a site already, a `TypeError` is raised when one attempts to add a new site manager: >>> myfolder.setSiteManager(site.LocalSiteManager(myfolder)) Traceback (most recent call last): ... TypeError: Already a site There is also an adapter you can use to get the next site manager from any location: >>> myfolder['mysubfolder'] = folder.Folder() >>> import zope.component >>> zope.component.interfaces.IComponentLookup(myfolder['mysubfolder']) is sm True If the location passed is a site, the site manager of that site is returned: >>> zope.component.interfaces.IComponentLookup(myfolder) is sm True Using the Site Manager ---------------------- A site manager contains several *site management folders*, which are used to logically organize the software. When a site manager is initialized, a default site management folder is created: >>> sm = myfolder.getSiteManager() >>> default = sm['default'] >>> default.__class__ However, you can tell not to create the default site manager folder on LocalSiteManager creation: >>> nodefault = site.LocalSiteManager(myfolder, default_folder=False) >>> 'default' in nodefault False Also, note that when creating LocalSiteManager, its __parent__ is set to site that was passed to constructor and the __name__ is set to ++etc++site. >>> nodefault.__parent__ is myfolder True >>> nodefault.__name__ == '++etc++site' True You can easily create a new site management folder: >>> sm['mySMF'] = site.SiteManagementFolder() >>> sm['mySMF'].__class__ Once you have your site management folder -- let's use the default one -- we can register some components. Let's start with a utility: >>> import zope.interface >>> class IMyUtility(zope.interface.Interface): ... pass >>> import persistent >>> from zope.container.contained import Contained >>> class MyUtility(persistent.Persistent, Contained): ... zope.interface.implements(IMyUtility) ... def __init__(self, title): ... self.title = title ... def __repr__(self): ... return "%s('%s')" %(self.__class__.__name__, self.title) Now we can create an instance of our utility and put it in the site management folder and register it: >>> myutil = MyUtility('My custom utility') >>> default['myutil'] = myutil >>> sm.registerUtility(myutil, IMyUtility, 'u1') Now we can ask the site manager for the utility: >>> sm.queryUtility(IMyUtility, 'u1') MyUtility('My custom utility') Of course, the local site manager has also access to the global component registrations: >>> gutil = MyUtility('Global Utility') >>> from zope.component import getGlobalSiteManager >>> gsm = getGlobalSiteManager() >>> gsm.registerUtility(gutil, IMyUtility, 'gutil') >>> sm.queryUtility(IMyUtility, 'gutil') MyUtility('Global Utility') Next let's see whether we can also successfully register an adapter as well. Here the adapter will provide the size of a file: >>> class IFile(zope.interface.Interface): ... pass >>> class ISized(zope.interface.Interface): ... pass >>> class File(object): ... zope.interface.implements(IFile) >>> class FileSize(object): ... zope.interface.implements(ISized) ... def __init__(self, context): ... self.context = context Now that we have the adapter we need to register it: >>> sm.registerAdapter(FileSize, [IFile]) Finally, we can get the adapter for a file: >>> file = File() >>> size = sm.queryAdapter(file, ISized, name='') >>> size.__class__ >>> size.context is file True By the way, once you set a site >>> from zope.component import hooks >>> hooks.setSite(myfolder) you can simply use the zope.component's `getSiteManager()` method to get the nearest site manager: >>> from zope.component import getSiteManager >>> getSiteManager() is sm True This also means that you can simply use zope.component to look up your utility >>> from zope.component import getUtility >>> getUtility(IMyUtility, 'gutil') MyUtility('Global Utility') or the adapter via the interface's `__call__` method: >>> size = ISized(file) >>> size.__class__ >>> size.context is file True Multiple Sites -------------- Until now we have only dealt with one local and the global site. But things really become interesting, once we have multiple sites. We can override other local configuration. This behaviour uses the notion of location, therefore we need to configure the zope.location package first: >>> import zope.configuration.xmlconfig >>> _ = zope.configuration.xmlconfig.string(""" ... ... ... ... ... """) Let's now create a new folder called `folder11`, add it to `myfolder` and make it a site: >>> myfolder11 = folder.Folder() >>> myfolder['myfolder11'] = myfolder11 >>> myfolder11.setSiteManager(site.LocalSiteManager(myfolder11)) >>> sm11 = myfolder11.getSiteManager() If we ask the second site manager for its next, we get >>> sm11.__bases__ == (sm, ) True and the first site manager should have the folling sub manager: >>> sm.subs == (sm11,) True If we now register a second utility with the same name and interface with the new site manager folder, >>> default11 = sm11['default'] >>> myutil11 = MyUtility('Utility, uno & uno') >>> default11['myutil'] = myutil11 >>> sm11.registerUtility(myutil11, IMyUtility, 'u1') then it will will be available in the second site manager >>> sm11.queryUtility(IMyUtility, 'u1') MyUtility('Utility, uno & uno') but not in the first one: >>> sm.queryUtility(IMyUtility, 'u1') MyUtility('My custom utility') It is also interesting to look at the use cases of moving and copying a site. To do that we create a second root folder and make it a site, so that site hierarchy is as follows: :: _____ global site _____ / \ myfolder1 myfolder2 | myfolder11 >>> myfolder2 = folder.rootFolder() >>> myfolder2.setSiteManager(site.LocalSiteManager(myfolder2)) Before we can move or copy sites, we need to register two event subscribers that manage the wiring of site managers after moving or copying: >>> from zope import container >>> gsm.registerHandler( ... site.changeSiteConfigurationAfterMove, ... (ISite, container.interfaces.IObjectMovedEvent), ... ) We only have to register one event listener, since the copy action causes an `IObjectAddedEvent` to be created, which is just a special type of `IObjectMovedEvent`. First, make sure that everything is setup correctly in the first place: >>> myfolder11.getSiteManager().__bases__ == (myfolder.getSiteManager(), ) True >>> myfolder.getSiteManager().subs[0] is myfolder11.getSiteManager() True >>> myfolder2.getSiteManager().subs () Let's now move `myfolder11` from `myfolder` to `myfolder2`: >>> myfolder2['myfolder21'] = myfolder11 >>> del myfolder['myfolder11'] Now the next site manager for `myfolder11`'s site manager should have changed: >>> myfolder21 = myfolder11 >>> myfolder21.getSiteManager().__bases__ == (myfolder2.getSiteManager(), ) True >>> myfolder2.getSiteManager().subs[0] is myfolder21.getSiteManager() True >>> myfolder.getSiteManager().subs () Make sure that our interfaces and classes are picklable: >>> import sys >>> sys.modules['zope.site.tests'].IMyUtility = IMyUtility >>> IMyUtility.__module__ = 'zope.site.tests' >>> sys.modules['zope.site.tests'].MyUtility = MyUtility >>> MyUtility.__module__ = 'zope.site.tests' >>> from pickle import dumps, loads >>> data = dumps(myfolder2['myfolder21']) >>> myfolder['myfolder11'] = loads(data) >>> myfolder11 = myfolder['myfolder11'] >>> myfolder11.getSiteManager().__bases__ == (myfolder.getSiteManager(), ) True >>> myfolder.getSiteManager().subs[0] is myfolder11.getSiteManager() True >>> myfolder2.getSiteManager().subs[0] is myfolder21.getSiteManager() True Finally, let's check that everything works fine when our folder is moved to the folder that doesn't contain any site manager. Our folder's sitemanager's bases should be set to global site manager. >>> myfolder11.getSiteManager().__bases__ == (myfolder.getSiteManager(), ) True >>> nosm = folder.Folder() >>> nosm['root'] = myfolder11 >>> myfolder11.getSiteManager().__bases__ == (gsm, ) True ======= CHANGES ======= 3.9.2 (2010-09-25) ------------------ - Added not declared, but needed test dependency on `zope.testing`. 3.9.1 (2010-04-30) ------------------ - Removed use of 'zope.testing.doctest' in favor of stdlib's 'doctest. - Removed use of 'zope.testing.doctestunit' in favor of stdlib's 'doctest. 3.9.0 (2009-12-29) ------------------ - Avoid a test dependency on zope.copypastemove by testing the correct persistent behavior of a site manager using the normal pickle module. 3.8.0 (2009-12-15) ------------------ - Removed functional testing setup and dependency on zope.app.testing. 3.7.1 (2009-11-18) ------------------ - Moved the zope.site.hooks functionality to zope.component.hooks as it isn't actually dealing with zope.site's concept of a site. - Import ISite and IPossibleSite from zope.component after they were moved there from zope.location. 3.7.0 (2009-09-29) ------------------ - Cleaned up the undeclared dependency on zope.app.publication by moving the two relevant subscriber registrations and their tests to that package. - Dropped the dependency on zope.traversing which was only used to access zope.location functionality. Configure zope.location for some tests. - Demoted zope.configuration to a testing dependency. 3.6.4 (2009-09-01) ------------------ - Set __parent__ and __name__ in the LocalSiteManager's constructor after calling constructor of its superclasses, so __name__ doesn't get overwritten with empty string by the Components constructor. - Don't set __parent__ and __name__ attributes of site manager in SiteManagerContainer's ``setSiteManager`` method, as they're already set for LocalSiteManager. Other site manager implementations are not required to have those attributes at all, so we're not adding them anymore. 3.6.3 (2009-07-27) ------------------ - Propagate an ObjectRemovedEvent to the SiteManager upon removal of a SiteManagerContainer. 3.6.2 (2009-07-24) ------------------ - Fixed tests to pass with latest packages. - Removed failing test of persistent interfaces, since it did not test anything in this package and used the deprecated ``zodbcode`` module. - Fix NameError when calling ``zope.site.testing.siteSetUp(site=True)``. - The ``getNextUtility`` and ``queryNextUtility`` functions was moved to ``zope.component``. While backward-compatibility imports are provided, it's strongly recommended to update your imports. 3.6.1 (2009-02-28) ------------------ - Import symbols moved from zope.traversing to zope.location from the new location. - Don't fail when changing component registry bases while moving ISite object to non-ISite object. - Allow specify whether to create 'default' SiteManagementFolder on initializing LocalSiteManager. Use the ``default_folder`` argument. - Add a containment constraint to the SiteManagementFolder that makes it only available to be contained in ILocalSiteManagers and other ISiteManagementFolders. - Change package's mailing list address to zope-dev at zope.org, as zope3-dev at zope.org is now retired. - Remove old unused code. Update package description. 3.6.0 (2009-01-31) ------------------ - Use zope.container instead of zope.app.container. 3.5.1 (2009-01-27) ------------------ - Extracted from zope.app.component (trunk, 3.5.1 under development) as part of an effort to clean up dependencies between Zope packages.

This also includes support for traversal namespaces (e.g. ``++view++``, ``++skin++``, etc.) as well as computing URLs via the ``@@absolute_url`` view. ======= Changes ======= 3.13.2 (2011-03-02) ------------------- - Re-release of 3.13.0. 3.13.1 introduced dependencies unsuitable for a bugfix release. 3.13.1 (2010-12-14) ------------------- - Fixed ZCML-related dependencies. 3.13 (2010-07-09) ----------------- - When a ``__parent__`` attribute is available on an object, it is always used for absolute URL construction, and no ILocation adapter lookup is performed for it. This was the previous behavior but was broken (around 3.5?) due to dependency refactoring. If the object provides no ``__parent__`` then an ILocation adapter lookup will be performed. This will always succeed as zope.location provides a default LocationProxy for everything, but more specific ILocation adapters can also be provided. 3.12.1 (2010-04-30) ------------------- - Removed use of 'zope.testing.doctestunit' in favor of stdlib's doctest. 3.12.0 (2009-12-29) ------------------- - Avoid testing dependencies on zope.securitypolicies and zope.principalregistry. 3.11.0 (2009-12-27) ------------------- - Removed testing dependency on zope.app.publication. 3.10.0 (2009-12-16) ------------------- - Removed stray test claiming a no longer existing dependency on zope.app.applicationcontrol. - Refactored functional tests to loose dependency on both zope.app.appsetup and zope.app.testing. - Simplified tests for the browser sub-package by using PlacelessSetup from zope.component.testing instead of zope.app.testing. - Simplified test_dependencies module by using zope.configuration instead of zope.app.testing.functional. - Removed testing dependency on zope.app.publisher. - Replaced testing dependency on zope.app.security with zope.securitypolicy. - Removed testing dependency on zope.app.zcmlfiles in favor of more explicit dependencies. - Removed testing dependency on zope.app.component. - Replaced a test dependency on zope.app.zptpage with a dependency on zope.pagetemplate. 3.9.0 (2009-12-15) ------------------ - Moved IBeforeTraverseEvent from zope.app.publication into this package, as we already deal with publication traversal. 3.8.0 (2009-09-29) ------------------ - In zope.traversing.api.getParent(), try to delegate to zope.location.interfaces.ILocationInfo.getParent(), analogous to getParents(). Keep returning the traversal parent as a fallback. - Brought ITraverser back from zope.location where it had been moved to invert the package interdependency, but is no longer used now. 3.7.2 (2009-08-29) ------------------ - Made virtual hosting tests compatible with zope.publisher 3.9. Redirecting to a different host requires an explicit `trusted` redirect now. 3.7.1 (2009-06-16) ------------------ - AbsoluteURL now implements the fact that __call__ returns the same as __str__ in a manner that it applies for subclasses, too, so they only have to override __str__ and not both. 3.7.0 (2009-05-23) ------------------ - Moved the publicationtraverse module to zope.traversing, removing the zope.app.publisher -> zope.app.publication dependency (which was a cycle). - Look up the application controller through a utility registration rather than a direct reference. 3.6.0 (2009-04-06) ------------------ - Change configure.zcml to not depend on zope.app.component. - This release includes the BBB-incompatible ``zope.publisher.skinnable`` change from 3.5.3. 3.5.4 (2009-04-06) ------------------ - Revert BBB-incompatible use of ``zope.publisher.skinnable``: that change belongs in a 3.6.0 release, because it requires a BBB-incompatible version of ``zope.publisher``. 3.5.3 (2009-03-10) ------------------ - Use applySkin from new location. zope.publisher.skinnable instead of zope.publisher.browser. - Use IAbsoluteURL lookup instead of the "absolute_url" view in the recursive AbsoluteURL adapters (LP: #338101). 3.5.2 (2009-02-04) ------------------ - The RootPhysicallyLocatable is not the same as LocationPhysicallyLocatable now in zope.location. Fix the import and testing setups. 3.5.1 (2009-02-02) ------------------ - The ``RootPhysicallyLocatable`` adapter has been superseded by the refactored ``zope.location.traversing.LocationPhysicallyLocatable`` that we depend on since 3.5.0a4. Remove the adapter and its registration, and making its import place pointing to ``zope.location.traversing.LocationPhysicallyLocatable`` to maintain backward-compatibility. This also fixes a bug introduced in version 3.5.0a4 when trying to call ``getParents`` function for the root object. - Use direct imports instead of compatibility ones for things that were moved to ``zope.location``. - Remove the ``zope.traversing.interfaces.INamespaceHandler`` interface, as it seems not to be used for years. - Change package's mailing list address to zope-dev at zope.org instead of retired zope3-dev at zope.org 3.5.0 (2009-01-31) ------------------ - Use zope.container instead of zope.app.container. - Use zope.site instead of zope.app.folder in the unit tests. - Reduced, but did not eliminate, test dependencies on zope.app.component. 3.5.0a4 (2008-08-01) -------------------- - Reverse dependencies between zope.location and zope.traversing. - Updated (test) dependencies and tests to expect and work with a spec compliant TAL interpreter as available in zope.tal >= 3.5.0. - Fixed deprecation warning caused by using an old module name for ZopeSecurityPolicy in ftesting.zcml - Made sure traversing doesn't raise an TypeError but a TraversalError when the traversal step before yielded a string. 3.5.0a3 (2007-12-28) -------------------- - backed out the controversial `++skin++` traverser for XML-RPC. 3.5.0a2 (2007-11-28) -------------------- - ported 3.4.1a1 to trunk - Do not use unicode strings to set the application server in the virtual host namespace. This caused absolute_url to create unicode URL's. - Added a traverer for ++skin++ for XMLRPC skins (IXMLRPCSkinType). This also means that the normal ++skin++ namespace handler is only bound to IBrowserRequest. - Resolved the dependency on zope.app.applicationcontrol by importing the application controller only if the package is available. 3.4.1 (2008-07-30) ------------------ - Fixed deprecation warning caused by using an old module name for ZopeSecurityPolicy in ftesting.zcml 3.4.1a1 (2007-11-13) -------------------- Do not use unicode strings to set the application server in the virtual host namespace. This caused absolute_url to create unicode URL's. 3.4.0 (2007-09-29) ------------------ No further changes since 3.4.0a1. 3.4.0a1 (2007-04-22) -------------------- Initial release as a separate project, corresponds to zope.traversing from Zope 3.4.0a1 Platform: UNKNOWN zope2.13-2.13.21/source/zope.traversing/pip-egg-info/0000755000175000017500000000000012214017660021057 5ustar arnauarnauzope2.13-2.13.21/source/zope.traversing/pip-egg-info/zope.traversing.egg-info/0000755000175000017500000000000012214017660025711 5ustar arnauarnauzope2.13-2.13.21/source/zope.traversing/pip-egg-info/zope.traversing.egg-info/PKG-INFO0000644000175000017500000002200412214017660027004 0ustar arnauarnauMetadata-Version: 1.0 Name: zope.traversing Version: 3.13.2 Summary: Resolving paths in the object hierarchy Home-page: http://pypi.python.org/pypi/zope.traversing Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: The ``zope.traversing`` package provides adapteres for resolving object paths by traversing an object hierarchy.

Redirecting to a different host requires an explicit `trusted` redirect now. 3.7.1 (2009-06-16) ------------------ - AbsoluteURL now implements the fact that __call__ returns the same as __str__ in a manner that it applies for subclasses, too, so they only have to override __str__ and not both. 3.7.0 (2009-05-23) ------------------ - Moved the publicationtraverse module to zope.traversing, removing the zope.app.publisher -> zope.app.publication dependency (which was a cycle). - Look up the application controller through a utility registration rather than a direct reference. 3.6.0 (2009-04-06) ------------------ - Change configure.zcml to not depend on zope.app.component. - This release includes the BBB-incompatible ``zope.publisher.skinnable`` change from 3.5.3. 3.5.4 (2009-04-06) ------------------ - Revert BBB-incompatible use of ``zope.publisher.skinnable``: that change belongs in a 3.6.0 release, because it requires a BBB-incompatible version of ``zope.publisher``. 3.5.3 (2009-03-10) ------------------ - Use applySkin from new location. zope.publisher.skinnable instead of zope.publisher.browser. - Use IAbsoluteURL lookup instead of the "absolute_url" view in the recursive AbsoluteURL adapters (LP: #338101). 3.5.2 (2009-02-04) ------------------ - The RootPhysicallyLocatable is not the same as LocationPhysicallyLocatable now in zope.location. Fix the import and testing setups. 3.5.1 (2009-02-02) ------------------ - The ``RootPhysicallyLocatable`` adapter has been superseded by the refactored ``zope.location.traversing.LocationPhysicallyLocatable`` that we depend on since 3.5.0a4. Remove the adapter and its registration, and making its import place pointing to ``zope.location.traversing.LocationPhysicallyLocatable`` to maintain backward-compatibility. This also fixes a bug introduced in version 3.5.0a4 when trying to call ``getParents`` function for the root object. - Use direct imports instead of compatibility ones for things that were moved to ``zope.location``. - Remove the ``zope.traversing.interfaces.INamespaceHandler`` interface, as it seems not to be used for years. - Change package's mailing list address to zope-dev at zope.org instead of retired zope3-dev at zope.org 3.5.0 (2009-01-31) ------------------ - Use zope.container instead of zope.app.container. - Use zope.site instead of zope.app.folder in the unit tests. - Reduced, but did not eliminate, test dependencies on zope.app.component. 3.5.0a4 (2008-08-01) -------------------- - Reverse dependencies between zope.location and zope.traversing. - Updated (test) dependencies and tests to expect and work with a spec compliant TAL interpreter as available in zope.tal >= 3.5.0. - Fixed deprecation warning caused by using an old module name for ZopeSecurityPolicy in ftesting.zcml - Made sure traversing doesn't raise an TypeError but a TraversalError when the traversal step before yielded a string. 3.5.0a3 (2007-12-28) -------------------- - backed out the controversial `++skin++` traverser for XML-RPC. 3.5.0a2 (2007-11-28) -------------------- - ported 3.4.1a1 to trunk - Do not use unicode strings to set the application server in the virtual host namespace. This caused absolute_url to create unicode URL's. - Added a traverer for ++skin++ for XMLRPC skins (IXMLRPCSkinType). This also means that the normal ++skin++ namespace handler is only bound to IBrowserRequest. - Resolved the dependency on zope.app.applicationcontrol by importing the application controller only if the package is available. 3.4.1 (2008-07-30) ------------------ - Fixed deprecation warning caused by using an old module name for ZopeSecurityPolicy in ftesting.zcml 3.4.1a1 (2007-11-13) -------------------- Do not use unicode strings to set the application server in the virtual host namespace. This caused absolute_url to create unicode URL's. 3.4.0 (2007-09-29) ------------------ No further changes since 3.4.0a1. 3.4.0a1 (2007-04-22) -------------------- Initial release as a separate project, corresponds to zope.traversing from Zope 3.4.0a1 Platform: UNKNOWN zope2.13-2.13.21/source/zope.traversing/pip-egg-info/zope.traversing.egg-info/dependency_links.txt0000644000175000017500000000000112214017660031757 0ustar arnauarnau zope2.13-2.13.21/source/zope.traversing/pip-egg-info/zope.traversing.egg-info/requires.txt0000644000175000017500000000042312214017660030310 0ustar arnauarnausetuptools zope.component zope.i18n zope.i18nmessageid zope.interface zope.proxy zope.publisher zope.security zope.location>=3.7.0 [test] zope.browserpage zope.browserresource zope.configuration zope.container zope.pagetemplate zope.site zope.tal >= 3.5.0 zope.testing ZODB3zope2.13-2.13.21/source/zope.traversing/pip-egg-info/zope.traversing.egg-info/namespace_packages.txt0000644000175000017500000000000512214017660032237 0ustar arnauarnauzope zope2.13-2.13.21/source/zope.traversing/pip-egg-info/zope.traversing.egg-info/top_level.txt0000644000175000017500000000000512214017660030436 0ustar arnauarnauzope zope2.13-2.13.21/source/zope.traversing/pip-egg-info/zope.traversing.egg-info/SOURCES.txt0000644000175000017500000000252012214017660027574 0ustar arnauarnauREADME.txt setup.cfg pip-egg-info/zope.traversing.egg-info/PKG-INFO pip-egg-info/zope.traversing.egg-info/SOURCES.txt pip-egg-info/zope.traversing.egg-info/dependency_links.txt pip-egg-info/zope.traversing.egg-info/namespace_packages.txt pip-egg-info/zope.traversing.egg-info/not-zip-safe pip-egg-info/zope.traversing.egg-info/requires.txt pip-egg-info/zope.traversing.egg-info/top_level.txt src/zope/__init__.py src/zope/traversing/__init__.py src/zope/traversing/adapters.py src/zope/traversing/api.py src/zope/traversing/interfaces.py src/zope/traversing/namespace.py src/zope/traversing/publicationtraverse.py src/zope/traversing/testing.py src/zope/traversing/browser/__init__.py src/zope/traversing/browser/absoluteurl.py src/zope/traversing/browser/interfaces.py src/zope/traversing/browser/tests.py src/zope/traversing/tests/__init__.py src/zope/traversing/tests/test_conveniencefunctions.py src/zope/traversing/tests/test_dependencies.py src/zope/traversing/tests/test_lang.py src/zope/traversing/tests/test_namespacetrversal.py src/zope/traversing/tests/test_physicallocationadapters.py src/zope/traversing/tests/test_presentation.py src/zope/traversing/tests/test_publicationtraverse.py src/zope/traversing/tests/test_skin.py src/zope/traversing/tests/test_traverser.py src/zope/traversing/tests/test_vh.py src/zope/traversing/tests/test_vhosting.pyzope2.13-2.13.21/source/zope.traversing/pip-egg-info/zope.traversing.egg-info/not-zip-safe0000644000175000017500000000000112214017660030137 0ustar arnauarnau zope2.13-2.13.21/source/zope.traversing/LICENSE.txt0000644000175000017500000000402612214017660020423 0ustar arnauarnauZope Public License (ZPL) Version 2.1 A copyright notice accompanies this license document that identifies the copyright holders.

This was the previous behavior but was broken (around 3.5?) due to dependency refactoring. If the object provides no ``__parent__`` then an ILocation adapter lookup will be performed. This will always succeed as zope.location provides a default LocationProxy for everything, but more specific ILocation adapters can also be provided. 3.12.1 (2010-04-30) ------------------- - Removed use of 'zope.testing.doctestunit' in favor of stdlib's doctest. 3.12.0 (2009-12-29) ------------------- - Avoid testing dependencies on zope.securitypolicies and zope.principalregistry. 3.11.0 (2009-12-27) ------------------- - Removed testing dependency on zope.app.publication. 3.10.0 (2009-12-16) ------------------- - Removed stray test claiming a no longer existing dependency on zope.app.applicationcontrol. - Refactored functional tests to loose dependency on both zope.app.appsetup and zope.app.testing. - Simplified tests for the browser sub-package by using PlacelessSetup from zope.component.testing instead of zope.app.testing. - Simplified test_dependencies module by using zope.configuration instead of zope.app.testing.functional. - Removed testing dependency on zope.app.publisher. - Replaced testing dependency on zope.app.security with zope.securitypolicy. - Removed testing dependency on zope.app.zcmlfiles in favor of more explicit dependencies. - Removed testing dependency on zope.app.component. - Replaced a test dependency on zope.app.zptpage with a dependency on zope.pagetemplate. 3.9.0 (2009-12-15) ------------------ - Moved IBeforeTraverseEvent from zope.app.publication into this package, as we already deal with publication traversal. 3.8.0 (2009-09-29) ------------------ - In zope.traversing.api.getParent(), try to delegate to zope.location.interfaces.ILocationInfo.getParent(), analogous to getParents().

This also includes support for traversal namespaces (e.g. ``++view++``, ``++skin++``, etc.) as well as computing URLs via the ``@@absolute_url`` view. ======= Changes ======= 3.13.2 (2011-03-02) ------------------- - Re-release of 3.13.0. 3.13.1 introduced dependencies unsuitable for a bugfix release. 3.13.1 (2010-12-14) ------------------- - Fixed ZCML-related dependencies. 3.13 (2010-07-09) ----------------- - When a ``__parent__`` attribute is available on an object, it is always used for absolute URL construction, and no ILocation adapter lookup is performed for it. This was the previous behavior but was broken (around 3.5?) due to dependency refactoring. If the object provides no ``__parent__`` then an ILocation adapter lookup will be performed. This will always succeed as zope.location provides a default LocationProxy for everything, but more specific ILocation adapters can also be provided. 3.12.1 (2010-04-30) ------------------- - Removed use of 'zope.testing.doctestunit' in favor of stdlib's doctest. 3.12.0 (2009-12-29) ------------------- - Avoid testing dependencies on zope.securitypolicies and zope.principalregistry. 3.11.0 (2009-12-27) ------------------- - Removed testing dependency on zope.app.publication. 3.10.0 (2009-12-16) ------------------- - Removed stray test claiming a no longer existing dependency on zope.app.applicationcontrol. - Refactored functional tests to loose dependency on both zope.app.appsetup and zope.app.testing. - Simplified tests for the browser sub-package by using PlacelessSetup from zope.component.testing instead of zope.app.testing. - Simplified test_dependencies module by using zope.configuration instead of zope.app.testing.functional. - Removed testing dependency on zope.app.publisher. - Replaced testing dependency on zope.app.security with zope.securitypolicy. - Removed testing dependency on zope.app.zcmlfiles in favor of more explicit dependencies. - Removed testing dependency on zope.app.component. - Replaced a test dependency on zope.app.zptpage with a dependency on zope.pagetemplate. 3.9.0 (2009-12-15) ------------------ - Moved IBeforeTraverseEvent from zope.app.publication into this package, as we already deal with publication traversal. 3.8.0 (2009-09-29) ------------------ - In zope.traversing.api.getParent(), try to delegate to zope.location.interfaces.ILocationInfo.getParent(), analogous to getParents(). Keep returning the traversal parent as a fallback. - Brought ITraverser back from zope.location where it had been moved to invert the package interdependency, but is no longer used now. 3.7.2 (2009-08-29) ------------------ - Made virtual hosting tests compatible with zope.publisher 3.9. Redirecting to a different host requires an explicit `trusted` redirect now. 3.7.1 (2009-06-16) ------------------ - AbsoluteURL now implements the fact that __call__ returns the same as __str__ in a manner that it applies for subclasses, too, so they only have to override __str__ and not both. 3.7.0 (2009-05-23) ------------------ - Moved the publicationtraverse module to zope.traversing, removing the zope.app.publisher -> zope.app.publication dependency (which was a cycle). - Look up the application controller through a utility registration rather than a direct reference. 3.6.0 (2009-04-06) ------------------ - Change configure.zcml to not depend on zope.app.component. - This release includes the BBB-incompatible ``zope.publisher.skinnable`` change from 3.5.3. 3.5.4 (2009-04-06) ------------------ - Revert BBB-incompatible use of ``zope.publisher.skinnable``: that change belongs in a 3.6.0 release, because it requires a BBB-incompatible version of ``zope.publisher``. 3.5.3 (2009-03-10) ------------------ - Use applySkin from new location. zope.publisher.skinnable instead of zope.publisher.browser. - Use IAbsoluteURL lookup instead of the "absolute_url" view in the recursive AbsoluteURL adapters (LP: #338101). 3.5.2 (2009-02-04) ------------------ - The RootPhysicallyLocatable is not the same as LocationPhysicallyLocatable now in zope.location. Fix the import and testing setups. 3.5.1 (2009-02-02) ------------------ - The ``RootPhysicallyLocatable`` adapter has been superseded by the refactored ``zope.location.traversing.LocationPhysicallyLocatable`` that we depend on since 3.5.0a4. Remove the adapter and its registration, and making its import place pointing to ``zope.location.traversing.LocationPhysicallyLocatable`` to maintain backward-compatibility. This also fixes a bug introduced in version 3.5.0a4 when trying to call ``getParents`` function for the root object. - Use direct imports instead of compatibility ones for things that were moved to ``zope.location``. - Remove the ``zope.traversing.interfaces.INamespaceHandler`` interface, as it seems not to be used for years. - Change package's mailing list address to zope-dev at zope.org instead of retired zope3-dev at zope.org 3.5.0 (2009-01-31) ------------------ - Use zope.container instead of zope.app.container. - Use zope.site instead of zope.app.folder in the unit tests. - Reduced, but did not eliminate, test dependencies on zope.app.component. 3.5.0a4 (2008-08-01) -------------------- - Reverse dependencies between zope.location and zope.traversing. - Updated (test) dependencies and tests to expect and work with a spec compliant TAL interpreter as available in zope.tal >= 3.5.0. - Fixed deprecation warning caused by using an old module name for ZopeSecurityPolicy in ftesting.zcml - Made sure traversing doesn't raise an TypeError but a TraversalError when the traversal step before yielded a string. 3.5.0a3 (2007-12-28) -------------------- - backed out the controversial `++skin++` traverser for XML-RPC. 3.5.0a2 (2007-11-28) -------------------- - ported 3.4.1a1 to trunk - Do not use unicode strings to set the application server in the virtual host namespace. This caused absolute_url to create unicode URL's. - Added a traverer for ++skin++ for XMLRPC skins (IXMLRPCSkinType). This also means that the normal ++skin++ namespace handler is only bound to IBrowserRequest. - Resolved the dependency on zope.app.applicationcontrol by importing the application controller only if the package is available. 3.4.1 (2008-07-30) ------------------ - Fixed deprecation warning caused by using an old module name for ZopeSecurityPolicy in ftesting.zcml 3.4.1a1 (2007-11-13) -------------------- Do not use unicode strings to set the application server in the virtual host namespace. This caused absolute_url to create unicode URL's. 3.4.0 (2007-09-29) ------------------ No further changes since 3.4.0a1. 3.4.0a1 (2007-04-22) -------------------- Initial release as a separate project, corresponds to zope.traversing from Zope 3.4.0a1 Platform: UNKNOWN zope2.13-2.13.21/source/zope.traversing/src/zope.traversing.egg-info/dependency_links.txt0000644000175000017500000000000112214017660030265 0ustar arnauarnau zope2.13-2.13.21/source/zope.traversing/src/zope.traversing.egg-info/requires.txt0000644000175000017500000000042312214017660026616 0ustar arnauarnausetuptools zope.component zope.i18n zope.i18nmessageid zope.interface zope.proxy zope.publisher zope.security zope.location>=3.7.0 [test] zope.browserpage zope.browserresource zope.configuration zope.container zope.pagetemplate zope.site zope.tal >= 3.5.0 zope.testing ZODB3zope2.13-2.13.21/source/zope.traversing/src/zope.traversing.egg-info/namespace_packages.txt0000644000175000017500000000000512214017660030545 0ustar arnauarnauzope zope2.13-2.13.21/source/zope.traversing/src/zope.traversing.egg-info/top_level.txt0000644000175000017500000000000512214017660026744 0ustar arnauarnauzope zope2.13-2.13.21/source/zope.traversing/src/zope.traversing.egg-info/SOURCES.txt0000644000175000017500000000270612214017660026110 0ustar arnauarnauCHANGES.txt COPYRIGHT.txt LICENSE.txt README.txt bootstrap.py buildout.cfg setup.py src/zope/__init__.py src/zope.traversing.egg-info/PKG-INFO src/zope.traversing.egg-info/SOURCES.txt src/zope.traversing.egg-info/dependency_links.txt src/zope.traversing.egg-info/namespace_packages.txt src/zope.traversing.egg-info/not-zip-safe src/zope.traversing.egg-info/requires.txt src/zope.traversing.egg-info/top_level.txt src/zope/traversing/__init__.py src/zope/traversing/adapters.py src/zope/traversing/api.py src/zope/traversing/configure.zcml src/zope/traversing/interfaces.py src/zope/traversing/namespace.py src/zope/traversing/publicationtraverse.py src/zope/traversing/testing.py src/zope/traversing/browser/__init__.py src/zope/traversing/browser/absoluteurl.py src/zope/traversing/browser/configure.zcml src/zope/traversing/browser/interfaces.py src/zope/traversing/browser/tests.py src/zope/traversing/tests/__init__.py src/zope/traversing/tests/ftesting.zcml src/zope/traversing/tests/test_conveniencefunctions.py src/zope/traversing/tests/test_dependencies.py src/zope/traversing/tests/test_lang.py src/zope/traversing/tests/test_namespacetrversal.py src/zope/traversing/tests/test_physicallocationadapters.py src/zope/traversing/tests/test_presentation.py src/zope/traversing/tests/test_publicationtraverse.py src/zope/traversing/tests/test_skin.py src/zope/traversing/tests/test_traverser.py src/zope/traversing/tests/test_vh.py src/zope/traversing/tests/test_vhosting.pyzope2.13-2.13.21/source/zope.traversing/src/zope.traversing.egg-info/not-zip-safe0000644000175000017500000000000112214017660026445 0ustar arnauarnau zope2.13-2.13.21/source/zope.testing/0000755000175000017500000000000012214017655016073 5ustar arnauarnauzope2.13-2.13.21/source/zope.testing/setup.py0000644000175000017500000000713212214017655017610 0ustar arnauarnau############################################################################## # # Copyright (c) 2004 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

This is intended to support functional tests that need to extract information from HTML forms returned by the publisher. See formparser.txt. loggingsupport.py Support for testing logging code If you want to test that your code generates proper log output, you can create and install a handler that collects output. loghandler.py Logging handler for tests that check logging output. module.py Lets a doctest pretend to be a Python module. See module.txt. renormalizing.py Regular expression pattern normalizing output checker. Useful for doctests. server.py Provides a simple HTTP server compatible with the zope.app.testing functional testing API. Lets you interactively play with the system under test. Helpful in debugging functional doctest failures. setupstack.py A simple framework for automating doctest set-up and tear-down. See setupstack.txt. testrunner The test runner package. This is typically wrapped by a test.py script that sets up options to run a particular set of tests. Getting started *************** zope.testing uses buildout. To start, run ``python bootstrap.py``. It will create a number of directories and the ``bin/buildout`` script. Next, run ``bin/buildout``. It will create a test script for you. Now, run ``bin/test`` to run the zope.testing test suite. zope.testing Changelog ********************** 3.9.7 (2011-11-02) ================== - Work around sporadic timing-related issues in the subprocess buffering tests. Thanks to Jonathan Ballet for the patch! 3.9.6 (2011-02-21) ================== - LP #719369: An `Unexpected success`_ (concept intruduced in Python 2.7) is no longer handled as success but as failure. This is a workaround. The whole unexpected success concept might be implemented later. .. _`Unexpected success`: http://www.voidspace.org.uk/python/articles/unittest2.shtml#more-skipping - Updated tests to run on Python 2.7, too. 3.9.5 (2010-05-19) ================== - LP #579019: When layers were run in parallel, their tearDown was not called. Additionally, the first layer which was run in the main thread did not have it's tearDown called either. - Deprecated zope.testing.testrunner and zope.testing.exceptions. They have been moved to a separate zope.testrunner module, and will be removed from zope.testing in 4.0.0, together with zope.testing.doctest. 3.9.4 (2010-04-13) ================== - LP #560259: Fix subunit output formatter to handle layer setup errors. - LP #399394: Added a ``--stop-on-error`` / ``--stop`` / ``-x`` option to the testrunner. - LP #498162: Added a ``--pdb`` alias for the existing ``--post-mortem`` / ``-D`` option to the testrunner. - LP #547023: Added a ``--version`` option to the testrunner. - Added tests for LP #144569 and #69988. https://bugs.launchpad.net/bugs/69988 https://bugs.launchpad.net/zope3/+bug/144569 3.9.3 (2010-03-26) ================== - zope.testing.renormalizer no longer imports zope.testing.doctest, which caused deprecation warnings. - Fix testrunner-layers-ntd.txt to suppress output to sys.stderr. - Suppress zope.testing.doctest deprecation warning when running zope.testing's own test suite. 3.9.2 (2010-03-15) ================== - Fixed broken ``from zope.testing.doctest import *`` 3.9.1 (2010-03-15) ================== - No changes; reuploaded to fix broken 3.9.0 release on PyPI. 3.9.0 (2010-03-12) ================== - Modified the testrunner to use the standard Python doctest module instead of the deprecated zope.testing.doctest. - Fix testrunner-leaks.txt to use the run_internal helper, so that sys.exit() isn't triggered during the test run. - Added support for conditionally using a subunit-based output formatter upon request if subunit and testtools are available. Patch contributed by Jonathan Lange. 3.8.6 (2009-12-23) ================== - Added MANIFEST.in and reuploaded to fix broken 3.8.5 release on PyPI. 3.8.5 (2009-12-23) ================== - Added DocFileSuite, DocTestSuite, debug_src and debug back BBB imports back into zope.testing.doctestunit; apparently many packages still import them from there! - Made zope.testing.doctest and zope.testing.doctestunit emit deprecation warnings: use the stdlib doctest instead. 3.8.4 (2009-12-18) ================== - Fixed missing imports and undefined variables reported by pyflakes, adding tests to exercise the blind spots. - Cleaned up unused imports reported by pyflakes. - Added two new options to generate randomly ordered list of tests and to select a specific order of tests. - RENormalizing checkers can be combined via ``+`` now: ``checker1 + checker2`` creates a checker with the transformations of both checkers. - Test fixes for Python 2.7. 3.8.3 (2009-09-21) ================== - Avoid a split() call or we get test failures when running from a directory with spaces in it. - Fix testrunner behavior on Windows for -j2 (or greater) combined with -v (or greater). 3.8.2 (2009-09-15) ================== - Removing hotshot profiler when using Python 2.6. That makes zope.testing compatible with Python 2.6 3.8.1 (2009-08-12) ================== - Avoid hardcoding sys.argv[0] as script; allow, for instance, Zope 2's `bin/instance test` (LP#407916). - Produce a clear error message when a subprocess doesn't follow the zope.testing.testrunner protocol (LP#407916). - Do not unnecessarily squelch verbose output in a subprocess when there are not multiple subprocesses. - Do not unnecessarily batch subprocess output, which can stymie automated and human processes for identifying hung tests. - Include incremental output when there are multiple subprocesses and a verbosity of -vv or greater is requested. This again is not batched, supporting automated processes and humans looking for hung tests. 3.8.0 (2009-07-24) ================== - Testrunner automatically picks up descendants of unittest.TestCase in test modules, so you don't have to provide a test_suite() anymore. 3.7.7 (2009-07-15) ================== - Clean up support for displaying tracebacks with supplements by turning it into an always-enabled feature and making the dependency on zope.exceptions explicit. - Fix #251759: Test runner descended into directories that aren't Python packages. - Code cleanups. 3.7.6 (2009-07-02) ================== - Add zope-testrunner console_scripts entry point. This exposes a zope-testrunner binary with default installs allowing the testrunner to be run from the command line. 3.7.5 (2009-06-08) ================== - Fix bug when running subprocesses on Windows. - The option REPORT_ONLY_FIRST_FAILURE (command line option "-1") is now respected even when a doctest declares its own REPORTING_FLAGS, such as REPORT_NDIFF. - Fixed bug that broke readline with pdb when using doctest (see http://bugs.python.org/issue5727). - Made tests pass on Windows and Linux at the same time. 3.7.4 (2009-05-01) ================== - Filenames of doctest examples now contain the line number and not only the example number. So a stack trace in pdb tells the exact line number of the current example. This fixes https://bugs.launchpad.net/bugs/339813 - Colorization of doctest output correctly handles blank lines. 3.7.3 (2009-04-22) ================== - Better deal with rogue threads by always exiting with status so even spinning daemon threads won't block the runner from exiting. This deprecated the ``--with-exit-status`` option. 3.7.2 (2009-04-13) ================== - fix test failure on Python 2.4 because of slight difference in the way coverage is reported (__init__ files with only a single comment line are now not reported) - fixed bug that caused the test runner to hang when running subprocesses (as a result Python 2.3 is no longer supported). - there is apparently a bug in Python 2.6 (related to http://bugs.python.org/issue1303673) that causes the profile tests to fail. - added explanitory notes to buildout.cfg about how to run the tests with multiple versions of Python 3.7.1 (2008-10-17) ================== - The setupstack temporary-directory support now properly handles read-only files by making them writable before removing them. 3.7.0 (2008-09-22) ================== - Added an alterate setuptools / distutils commands for running all tests using our testrunner. See 'zope.testing.testrunner.eggsupport:ftest'. - Added a setuptools-compatible test loader which skips tests with layers: the testrunner used by 'setup.py test' doesn't know about them, and those tests then fail. See 'zope.testing.testrunner.eggsupport:SkipLayers'. - Added support for Jython, when a garbage collector call is sent. - Added support to bootstrap on Jython. - Fixed NameError in StartUpFailure. - Open doctest files in universal mode, so that packages released in Windoes can be tested in Linux, for example. 3.6.0 (2008/07/10) ================== - Added -j option to parallel tests run in subprocesses. - RENormalizer accepts plain Python callables. - Added --slow-test option. - Added --no-progress and --auto-progress options. - Complete refactoring of the test runner into multiple code files and a more modular (pipeline-like) architecture. - Unified unit tests with the layer support by introducing a real unit test layer. - Added a doctest for ``zope.testing.module``. There were several bugs that were fixed: * ``README.txt`` was a really bad default argument for the module name, as it is not a proper dotted name. The code would immediately fail as it would look for the ``txt`` module in the ``README`` package. The default is now ``__main__``. * The tearDown function did not clean up the ``__name__`` entry in the global dictionary. - Fix a bug that caused a SubprocessError to be generated if a subprocess sent any output to stderr. - Fix a bug that caused the unit tests to be skipped if run in a subprocess. 3.5.1 (2007/08/14) ================== Bugs Fixed: ----------- - Post-mortem debugging wasn't invoked for layer-setup failures. 3.5.0 (2007/07/19) ================== New Features ------------ - The test runner now works on Python 2.5. - Added support for cProfile. - Added output colorizing (-c option). - Added --hide-secondary-failures and --show-secondary-failures options (https://bugs.launchpad.net/zope3/+bug/115454). Bugs Fixed: ----------- - Fix some problems with Unicode in doctests. - Fix "Error reading from subprocess" errors on Unix-like systems. 3.4 (2007/03/29) ================ New Features ------------ - Added exit-with-status support (supports use with buildbot and zc.recipe.testing) - Added a small framework for automating set up and tear down of doctest tests. See setupstack.txt. Bugs Fixed: ----------- - Fix testrunner-wo-source.txt and testrunner-errors.txt to run with a read-only source tree. 3.0 (2006/09/20) ================ - Updated the doctest copy with text-file encoding support. - Added logging-level support to loggingsuppport module. - At verbosity-level 1, dots are not output continuously, without any line breaks. - Improved output when the inability to tear down a layer causes tests to be run in a subprocess. - Made zope.exception required only if the zope_tracebacks extra is requested. 2.x.y (???) =========== - Fix the test coverage. If a module, for example `interfaces`, was in an ignored directory/package, then if a module of the same name existed in a covered directory/package, then it was also ignored there, because the ignore cache stored the result by module name and not the filename of the module. 2.0 (2006/01/05) ================ - Corresponds to the version of the zope.testing package shipped as part of the Zope 3.2.0 release. Detailed Documentation ********************** Test Runner =========== The testrunner module is used to run automated tests defined using the unittest framework. Its primary feature is that it *finds* tests by searching directory trees. It doesn't require the manual concatenation of specific test suites. It is highly customizable and should be usable with any project. In addition to finding and running tests, it provides the following additional features: - Test filtering using specifications of: o test packages within a larger tree o regular expression patterns for test modules o regular expression patterns for individual tests - Organization of tests into levels and layers Sometimes, tests take so long to run that you don't want to run them on every run of the test runner. Tests can be defined at different levels. The test runner can be configured to only run tests at a specific level or below by default. Command-line options can be used to specify a minimum level to use for a specific run, or to run all tests. Individual tests or test suites can specify their level via a 'level' attribute. where levels are integers increasing from 1. Most tests are unit tests. They don't depend on other facilities, or set up whatever dependencies they have. For larger applications, it's useful to specify common facilities that a large number of tests share. Making each test set up and and tear down these facilities is both ineffecient and inconvenient. For this reason, we've introduced the concept of layers, based on the idea of layered application architectures. Software build for a layer should be able to depend on the facilities of lower layers already being set up. For example, Zope defines a component architecture. Much Zope software depends on that architecture. We should be able to treat the component architecture as a layer that we set up once and reuse. Similarly, Zope application software should be able to depend on the Zope application server without having to set it up in each test. The test runner introduces test layers, which are objects that can set up environments for tests within the layers to use. A layer is set up before running the tests in it. Individual tests or test suites can define a layer by defining a `layer` attribute, which is a test layer. - Reporting - progress meter - summaries of tests run - Analysis of test execution - post-mortem debugging of test failures - memory leaks - code coverage - source analysis using pychecker - memory errors - execution times - profiling Simple Usage ============ The test runner consists of an importable module. The test runner is used by providing scripts that import and invoke the `run` method from the module. The `testrunner` module is controlled via command-line options. Test scripts supply base and default options by supplying a list of default command-line options that are processed before the user-supplied command-line options are provided. Typically, a test script does 2 things: - Adds the directory containing the zope package to the Python path. - Calls the test runner with default arguments and arguments supplied to the script. Normally, it just passes default/setup arguments. The test runner uses `sys.argv` to get the user's input. This testrunner_ex subdirectory contains a number of sample packages with tests. Let's run the tests found here. First though, we'll set up our default options: >>> import os.path >>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex') >>> defaults = [ ... '--path', directory_with_tests, ... '--tests-pattern', '^sampletestsf?$', ... ] The default options are used by a script to customize the test runner for a particular application. In this case, we use two options: path Set the path where the test runner should look for tests. This path is also added to the Python path. tests-pattern Tell the test runner how to recognize modules or packages containing tests. Now, if we run the tests, without any other options: >>> from zope.testing import testrunner >>> import sys >>> sys.argv = ['test'] >>> testrunner.run_internal(defaults) Running samplelayers.Layer1 tests: Set up samplelayers.Layer1 in N.NNN seconds. Ran 9 tests with 0 failures and 0 errors in N.NNN seconds. Running samplelayers.Layer11 tests: Set up samplelayers.Layer11 in N.NNN seconds. Ran 34 tests with 0 failures and 0 errors in N.NNN seconds. Running samplelayers.Layer111 tests: Set up samplelayers.Layerx in N.NNN seconds. Set up samplelayers.Layer111 in N.NNN seconds.

Running samplelayers.Layer122 tests: Tear down samplelayers.Layer121 in N.NNN seconds. Set up samplelayers.Layer122 in N.NNN seconds. Ran 34 tests with 0 failures and 0 errors in N.NNN seconds. Running zope.testing.testrunner.layer.UnitTests tests: Tear down samplelayers.Layer122 in N.NNN seconds. Tear down samplelayers.Layer12 in N.NNN seconds. Tear down samplelayers.Layer1 in N.NNN seconds. Set up zope.testing.testrunner.layer.UnitTests in N.NNN seconds. Ran 192 tests with 0 failures and 0 errors in N.NNN seconds. Tearing down left over layers: Tear down zope.testing.testrunner.layer.UnitTests in N.NNN seconds. Total: 405 tests, 0 failures, 0 errors in N.NNN seconds. False we see the normal testrunner output, which summarizes the tests run for each layer. For each layer, we see what layers had to be torn down or set up to run the layer and we see the number of tests run, with results. The test runner returns a boolean indicating whether there were errors. In this example, there were no errors, so it returned False. (Of course, the times shown in these examples are just examples. Times will vary depending on system speed.) Layers ====== A Layer is an object providing setup and teardown methods used to setup and teardown the environment provided by the layer. It may also provide setup and teardown methods used to reset the environment provided by the layer between each test. Layers are generally implemented as classes using class methods. >>> class BaseLayer: ... def setUp(cls): ... log('BaseLayer.setUp') ... setUp = classmethod(setUp) ... ... def tearDown(cls): ... log('BaseLayer.tearDown') ... tearDown = classmethod(tearDown) ... ... def testSetUp(cls): ... log('BaseLayer.testSetUp') ... testSetUp = classmethod(testSetUp) ... ... def testTearDown(cls): ... log('BaseLayer.testTearDown') ... testTearDown = classmethod(testTearDown) ... Layers can extend other layers. Note that they do not explicitly invoke the setup and teardown methods of other layers - the test runner does this for us in order to minimize the number of invocations. >>> class TopLayer(BaseLayer): ... def setUp(cls): ... log('TopLayer.setUp') ... setUp = classmethod(setUp) ... ... def tearDown(cls): ... log('TopLayer.tearDown') ... tearDown = classmethod(tearDown) ... ... def testSetUp(cls): ... log('TopLayer.testSetUp') ... testSetUp = classmethod(testSetUp) ... ... def testTearDown(cls): ... log('TopLayer.testTearDown') ... testTearDown = classmethod(testTearDown) ... Tests or test suites specify what layer they need by storing a reference in the 'layer' attribute. >>> import unittest >>> class TestSpecifyingBaseLayer(unittest.TestCase): ... 'This TestCase explicitly specifies its layer' ... layer = BaseLayer ... name = 'TestSpecifyingBaseLayer' # For testing only ... ... def setUp(self): ... log('TestSpecifyingBaseLayer.setUp') ... ... def tearDown(self): ... log('TestSpecifyingBaseLayer.tearDown') ... ... def test1(self): ... log('TestSpecifyingBaseLayer.test1') ... ... def test2(self): ... log('TestSpecifyingBaseLayer.test2') ... >>> class TestSpecifyingNoLayer(unittest.TestCase): ... 'This TestCase specifies no layer' ... name = 'TestSpecifyingNoLayer' # For testing only ... def setUp(self): ... log('TestSpecifyingNoLayer.setUp') ... ... def tearDown(self): ... log('TestSpecifyingNoLayer.tearDown') ... ... def test1(self): ... log('TestSpecifyingNoLayer.test') ... ... def test2(self): ... log('TestSpecifyingNoLayer.test') ... Create a TestSuite containing two test suites, one for each of TestSpecifyingBaseLayer and TestSpecifyingNoLayer. >>> umbrella_suite = unittest.TestSuite() >>> umbrella_suite.addTest(unittest.makeSuite(TestSpecifyingBaseLayer)) >>> no_layer_suite = unittest.makeSuite(TestSpecifyingNoLayer) >>> umbrella_suite.addTest(no_layer_suite) Before we can run the tests, we need to setup some helpers. >>> from zope.testing.testrunner import options >>> from zope.testing.loggingsupport import InstalledHandler >>> import logging >>> log_handler = InstalledHandler('zope.testing.tests') >>> def log(msg): ... logging.getLogger('zope.testing.tests').info(msg) >>> def fresh_options(): ... opts = options.get_options(['--test-filter', '.*']) ... opts.resume_layer = None ... opts.resume_number = 0 ... return opts Now we run the tests. Note that the BaseLayer was not setup when the TestSpecifyingNoLayer was run and setup/torn down around the TestSpecifyingBaseLayer tests. >>> from zope.testing.testrunner.runner import Runner >>> runner = Runner(options=fresh_options(), args=[], found_suites=[umbrella_suite]) >>> succeeded = runner.run() Running BaseLayer tests: Set up BaseLayer in N.NNN seconds. Ran 2 tests with 0 failures and 0 errors in N.NNN seconds. Running zope.testing.testrunner.layer.UnitTests tests: Tear down BaseLayer in N.NNN seconds. Set up zope.testing.testrunner.layer.UnitTests in N.NNN seconds. Ran 2 tests with 0 failures and 0 errors in N.NNN seconds. Tearing down left over layers: Tear down zope.testing.testrunner.layer.UnitTests in N.NNN seconds. Total: 4 tests, 0 failures, 0 errors in N.NNN seconds. Now lets specify a layer in the suite containing TestSpecifyingNoLayer and run the tests again. This demonstrates the other method of specifying a layer. This is generally how you specify what layer doctests need. >>> no_layer_suite.layer = BaseLayer >>> runner = Runner(options=fresh_options(), args=[], found_suites=[umbrella_suite]) >>> succeeded = runner.run() Running BaseLayer tests: Set up BaseLayer in N.NNN seconds. Ran 4 tests with 0 failures and 0 errors in N.NNN seconds. Tearing down left over layers: Tear down BaseLayer in N.NNN seconds. Clear our logged output, as we want to inspect it shortly. >>> log_handler.clear() Now lets also specify a layer in the TestSpecifyingNoLayer class and rerun the tests. This demonstrates that the most specific layer is used. It also shows the behavior of nested layers - because TopLayer extends BaseLayer, both the BaseLayer and TopLayer environments are setup when the TestSpecifyingNoLayer tests are run. >>> TestSpecifyingNoLayer.layer = TopLayer >>> runner = Runner(options=fresh_options(), args=[], found_suites=[umbrella_suite]) >>> succeeded = runner.run() Running BaseLayer tests: Set up BaseLayer in N.NNN seconds. Ran 2 tests with 0 failures and 0 errors in N.NNN seconds. Running TopLayer tests: Set up TopLayer in N.NNN seconds. Ran 2 tests with 0 failures and 0 errors in N.NNN seconds. Tearing down left over layers: Tear down TopLayer in N.NNN seconds. Tear down BaseLayer in N.NNN seconds. Total: 4 tests, 0 failures, 0 errors in N.NNN seconds. If we inspect our trace of what methods got called in what order, we can see that the layer setup and teardown methods only got called once. We can also see that the layer's test setup and teardown methods got called for each test using that layer in the right order. >>> def report(): ... for record in log_handler.records: ... print record.getMessage() >>> report() BaseLayer.setUp BaseLayer.testSetUp TestSpecifyingBaseLayer.setUp TestSpecifyingBaseLayer.test1 TestSpecifyingBaseLayer.tearDown BaseLayer.testTearDown BaseLayer.testSetUp TestSpecifyingBaseLayer.setUp TestSpecifyingBaseLayer.test2 TestSpecifyingBaseLayer.tearDown BaseLayer.testTearDown TopLayer.setUp BaseLayer.testSetUp TopLayer.testSetUp TestSpecifyingNoLayer.setUp TestSpecifyingNoLayer.test TestSpecifyingNoLayer.tearDown TopLayer.testTearDown BaseLayer.testTearDown BaseLayer.testSetUp TopLayer.testSetUp TestSpecifyingNoLayer.setUp TestSpecifyingNoLayer.test TestSpecifyingNoLayer.tearDown TopLayer.testTearDown BaseLayer.testTearDown TopLayer.tearDown BaseLayer.tearDown Now lets stack a few more layers to ensure that our setUp and tearDown methods are called in the correct order. >>> from zope.testing.testrunner.find import name_from_layer >>> class A(object): ... def setUp(cls): ... log('%s.setUp' % name_from_layer(cls)) ... setUp = classmethod(setUp) ... ... def tearDown(cls): ... log('%s.tearDown' % name_from_layer(cls)) ... tearDown = classmethod(tearDown) ... ... def testSetUp(cls): ... log('%s.testSetUp' % name_from_layer(cls)) ... testSetUp = classmethod(testSetUp) ... ... def testTearDown(cls): ... log('%s.testTearDown' % name_from_layer(cls)) ... testTearDown = classmethod(testTearDown) ... >>> class B(A): pass >>> class C(B): pass >>> class D(A): pass >>> class E(D): pass >>> class F(C,E): pass >>> class DeepTest(unittest.TestCase): ... layer = F ... def test(self): ... pass >>> suite = unittest.makeSuite(DeepTest) >>> log_handler.clear() >>> runner = Runner(options=fresh_options(), args=[], found_suites=[suite]) >>> succeeded = runner.run() Running F tests: Set up A in N.NNN seconds.

False Debugging ========= The testrunner module supports post-mortem debugging and debugging using `pdb.set_trace`. Let's look first at using `pdb.set_trace`. To demonstrate this, we'll provide input via helper Input objects: >>> class Input: ... def __init__(self, src): ... self.lines = src.split('\n') ... def readline(self): ... line = self.lines.pop(0) ... print line ... return line+'\n' If a test or code called by a test calls pdb.set_trace, then the runner will enter pdb at that point: >>> import os.path, sys >>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex') >>> from zope.testing import testrunner >>> defaults = [ ... '--path', directory_with_tests, ... '--tests-pattern', '^sampletestsf?$', ... ] >>> real_stdin = sys.stdin >>> if sys.version_info[:2] == (2, 3): ... sys.stdin = Input('n\np x\nc') ... else: ... sys.stdin = Input('p x\nc') >>> sys.argv = ('test -ssample3 --tests-pattern ^sampletests_d$' ... ' -t set_trace1').split() >>> try: testrunner.run_internal(defaults) ... finally: sys.stdin = real_stdin ... # doctest: +ELLIPSIS Running zope.testing.testrunner.layer.UnitTests tests: ... > testrunner-ex/sample3/sampletests_d.py(27)test_set_trace1() -> y = x (Pdb) p x 1 (Pdb) c Ran 1 tests with 0 failures and 0 errors in 0.001 seconds. ... False Note that, prior to Python 2.4, calling pdb.set_trace caused pdb to break in the pdb.set_trace function. It was necessary to use 'next' or 'up' to get to the application code that called pdb.set_trace. In Python 2.4, pdb.set_trace causes pdb to stop right after the call to pdb.set_trace. You can also do post-mortem debugging, using the --post-mortem (-D) option: >>> sys.stdin = Input('p x\nc') >>> sys.argv = ('test -ssample3 --tests-pattern ^sampletests_d$' ... ' -t post_mortem1 -D').split() >>> try: testrunner.run_internal(defaults) ... finally: sys.stdin = real_stdin ... # doctest: +NORMALIZE_WHITESPACE +REPORT_NDIFF Running zope.testing.testrunner.layer.UnitTests tests: ...

Only directories selected for testing should report coverage. The test runner provides a custom implementation of the relevant API. The ``TestIgnore`` class, the class managing the ignoring, is initialized by passing the command line options. It uses the options to determine the directories that should be covered. >>> class FauxOptions(object): ... package = None ... test_path = [('/myproject/src/blah/foo', ''), ... ('/myproject/src/blah/bar', '')] >>> from zope.testing.testrunner import coverage >>> from zope.testing.testrunner.find import test_dirs >>> ignore = coverage.TestIgnore(test_dirs(FauxOptions(), {})) >>> ignore._test_dirs ['/myproject/src/blah/foo/', '/myproject/src/blah/bar/'] We can now ask whether a particular module should be ignored: >>> ignore.names('/myproject/src/blah/foo/baz.py', 'baz') False >>> ignore.names('/myproject/src/blah/bar/mine.py', 'mine') False >>> ignore.names('/myproject/src/blah/foo/__init__.py', 'foo') False >>> ignore.names('/myproject/src/blah/hello.py', 'hello') True When running the test runner, modules are sometimes created from text strings. Those should *always* be ignored: >>> ignore.names('/myproject/src/blah/hello.txt', '') True To make this check fast, the class implements a cache. In an early implementation, the result was cached by the module name, which was a problem, since a lot of modules carry the same name (not the Python dotted name here!). So just because a module has the same name in an ignored and tested directory, does not mean it is always ignored: >>> ignore.names('/myproject/src/blah/module.py', 'module') True >>> ignore.names('/myproject/src/blah/foo/module.py', 'module') False Profiling ========= The testrunner supports hotshot and cProfile profilers.

We'll delete these ourselves: >>> import os >>> for f in files: ... os.unlink(f) Running Without Source Code =========================== The ``--usecompiled`` option allows running tests in a tree without .py source code, provided compiled .pyc or .pyo files exist (without ``--usecompiled``, .py files are necessary). We have a very simple directory tree, under ``usecompiled/``, to test this. Because we're going to delete its .py files, we want to work in a copy of that: >>> import os.path, shutil, sys, tempfile >>> directory_with_tests = tempfile.mkdtemp() >>> NEWNAME = "unlikely_package_name" >>> src = os.path.join(this_directory, 'testrunner-ex', 'usecompiled') >>> os.path.isdir(src) True >>> dst = os.path.join(directory_with_tests, NEWNAME) >>> os.path.isdir(dst) False Have to use our own copying code, to avoid copying read-only SVN files that can't be deleted later. >>> n = len(src) + 1 >>> for root, dirs, files in os.walk(src): ... dirs[:] = [d for d in dirs if d == "package"] # prune cruft ... os.mkdir(os.path.join(dst, root[n:])) ... for f in files: ... shutil.copy(os.path.join(root, f), ... os.path.join(dst, root[n:], f)) Now run the tests in the copy: >>> from zope.testing import testrunner >>> mydefaults = [ ... '--path', directory_with_tests, ... '--tests-pattern', '^compiletest$', ... '--package', NEWNAME, ...

Tearing down left over layers: Tear down zope.testing.testrunner.layer.UnitTests in N.NNN seconds. False If we delete the source files, it's normally a disaster: the test runner doesn't believe any test files, or even packages, exist. Note that we pass ``--keepbytecode`` this time, because otherwise the test runner would delete the compiled Python files too: >>> for root, dirs, files in os.walk(dst): ... for f in files: ... if f.endswith(".py"): ... os.remove(os.path.join(root, f)) >>> testrunner.run_internal(mydefaults, ["test", "--keepbytecode"]) Running tests at level 1 Total: 0 tests, 0 failures, 0 errors in N.NNN seconds. False Finally, passing ``--usecompiled`` asks the test runner to treat .pyc and .pyo files as adequate replacements for .py files. Note that the output is the same as when running with .py source above. The absence of "removing stale bytecode ..." messages shows that ``--usecompiled`` also implies ``--keepbytecode``: >>> testrunner.run_internal(mydefaults, ["test", "--usecompiled"]) Running tests at level 1 Running zope.testing.testrunner.layer.UnitTests tests: Set up zope.testing.testrunner.layer.UnitTests in N.NNN seconds.

Layers are set up and torn down only once. Garbage Collection Control ========================== When having problems that seem to be caused my memory-management errors, it can be helpful to adjust Python's cyclic garbage collector or to get garbage colection statistics. The --gc option can be used for this purpose. If you think you are getting a test failure due to a garbage collection problem, you can try disabling garbage collection by using the --gc option with a value of zero. >>> import os.path, sys >>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex') >>> defaults = ['--path', directory_with_tests] >>> from zope.testing import testrunner >>> sys.argv = 'test --tests-pattern ^gc0$ --gc 0 -vv'.split() >>> _ = testrunner.run_internal(defaults) Cyclic garbage collection is disabled.

Running: make_sure_gc_is_disabled (gc0) Ran 1 tests with 0 failures and 0 errors in N.NNN seconds. Tearing down left over layers: Tear down zope.testing.testrunner.layer.UnitTests in N.NNN seconds. Alternatively, if you think you are having a garbage collection related problem, you can cause garbage collection to happen more often by providing a low threshold: >>> sys.argv = 'test --tests-pattern ^gc1$ --gc 1 -vv'.split() >>> _ = testrunner.run_internal(defaults) Cyclic garbage collection threshold set to: (1,) Running tests at level 1 Running zope.testing.testrunner.layer.UnitTests tests: Set up zope.testing.testrunner.layer.UnitTests in N.NNN seconds.

Tearing down left over layers: Tear down zope.testing.testrunner.layer.UnitTests in N.NNN seconds. You can specify up to 3 --gc options to set each of the 3 gc threshold values: >>> sys.argv = ('test --tests-pattern ^gcset$ --gc 701 --gc 11 --gc 9 -vv' ... .split()) >>> _ = testrunner.run_internal(defaults) Cyclic garbage collection threshold set to: (701, 11, 9) Running tests at level 1 Running zope.testing.testrunner.layer.UnitTests tests: Set up zope.testing.testrunner.layer.UnitTests in N.NNN seconds.

Tearing down left over layers: Tear down zope.testing.testrunner.layer.UnitTests in N.NNN seconds.

SystemExit: 1 >>> sys.stdout = stdout >>> print out.getvalue() Too many --gc options Garbage Collection Statistics ----------------------------- You can enable gc debugging statistics using the --gc-options (-G) option. You should provide names of one or more of the flags described in the library documentation for the gc module. The output statistics are written to standard error. >>> from StringIO import StringIO >>> err = StringIO() >>> stderr = sys.stderr >>> sys.stderr = err >>> sys.argv = ('test --tests-pattern ^gcstats$ -G DEBUG_STATS' ...

Debugging Memory Leaks ====================== The --report-refcounts (-r) option can be used with the --repeat (-N) option to detect and diagnose memory leaks. To use this option, you must configure Python with the --with-pydebug option. (On Unix, pass this option to configure and then build Python.) >>> import os.path, sys >>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex') >>> defaults = [ ...

Tear down samplelayers.Layer1 in 0.000 seconds. Total: 68 tests, 0 failures, 0 errors in N.NNN seconds. Each layer is repeated the requested number of times. For each iteration after the first, the system refcount and change in system refcount is shown. The system refcount is the total of all refcount in the system. When a refcount on any object is changed, the system refcount is changed by the same amount. Tests that don't leak show zero changes in systen refcount. Let's look at an example test that leaks: >>> sys.argv = 'test --tests-pattern leak -N4 -r'.split() >>> _ = testrunner.run_internal(defaults) Running zope.testing.testrunner.layer.UnitTests tests:... Iteration 1 Ran 1 tests with 0 failures and 0 errors in 0.000 seconds. Iteration 2 Ran 1 tests with 0 failures and 0 errors in 0.000 seconds. sys refcount=92506 change=12 Iteration 3 Ran 1 tests with 0 failures and 0 errors in 0.000 seconds. sys refcount=92513 change=12 Iteration 4 Ran 1 tests with 0 failures and 0 errors in 0.000 seconds. sys refcount=92520 change=12 Tearing down left over layers: Tear down zope.testing.testrunner.layer.UnitTests in N.NNN seconds. Here we see that the system refcount is increating. If we specify a verbosity greater than one, we can get details broken out by object type (or class): >>> sys.argv = 'test --tests-pattern leak -N5 -r -v'.split() >>> _ = testrunner.run_internal(defaults) Running tests at level 1 Running zope.testing.testrunner.layer.UnitTests tests:...

It is instructive to analyze the results in some detail. The test being run was designed to intentionally leak: class ClassicLeakable: def __init__(self): self.x = 'x' class Leakable(object): def __init__(self): self.x = 'x' leaked = [] class TestSomething(unittest.TestCase): def testleak(self): leaked.append((ClassicLeakable(), Leakable(), time.time())) Let's go through this by type. float, leak.ClassicLeakable, leak.Leakable, and tuple We leak one of these every time. This is to be expected because we are adding one of these to the list every time. str We don't leak any instances, but we leak 4 references. These are due to the instance attributes avd values. dict We leak 2 of these, one for each ClassicLeakable and Leakable instance. classobj We increase the number of classobj instance references by one each time because each ClassicLeakable instance has a reference to its class. This instances increases the references in it's class, which increases the total number of references to classic classes (clasobj instances). type For most interations, we increase the number of type references by one for the same reason we increase the number of clasobj references by one. The increase of the number of type references by 3 in the second iteration is puzzling, but illustrates that this sort of data is often puzzling. int The change in the number of int instances and references in this example is a side effect of the statistics being gathered. Lots of integers are created to keep the memory statistics used here. The summary statistics include the sum of the detail refcounts. (Note that this sum is less than the system refcount. This is because the detailed analysis doesn't inspect every object. Not all objects in the system are returned by sys.getobjects.) Knitting in extra package directories ===================================== Python packages have __path__ variables that can be manipulated to add extra directories cntaining software used in the packages. The testrunner needs to be given extra information about this sort of situation. Let's look at an example. The testrunner-ex-knit-lib directory is a directory that we want to add to the Python path, but that we don't want to search for tests. It has a sample4 package and a products subpackage. The products subpackage adds the testrunner-ex-knit-products to it's __path__. We want to run tests from the testrunner-ex-knit-products directory. When we import these tests, we need to import them from the sample4.products package. We can't use the --path option to name testrunner-ex-knit-products. It isn't enough to add the containing directory to the test path because then we wouldn't be able to determine the package name properly. We might be able to use the --package option to run the tests from the sample4/products package, but we want to run tests in testrunner-ex that aren't in this package. We can use the --package-path option in this case. The --package-path option is like the --test-path option in that it defines a path to be searched for tests without affecting the python path. It differs in that it supplied a package name that is added a profex when importing any modules found. The --package-path option takes *two* arguments, a package name and file path. >>> import os.path, sys >>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex') >>> sys.path.append(os.path.join(this_directory, 'testrunner-ex-pp-lib')) >>> defaults = [ ...

Parsing HTML Forms ================== Sometimes in functional tests, information from a generated form must be extracted in order to re-submit it as part of a subsequent request. The `zope.testing.formparser` module can be used for this purpose. The scanner is implemented using the `FormParser` class. The constructor arguments are the page data containing the form and (optionally) the URL from which the page was retrieved: >>> import zope.testing.formparser >>> page_text = '''\ ... ...
    ... ... ... ... ...
    ... ... Just for fun, a second form, after specifying a base: ... ...
    ... ... ... ... ...

You specify a sequence of patterns and replacements. The replacements are applied to the expected and actual outputs before calling the default outputs checker. Let's look at an example. In this example, we have some times and addresses: >>> want = '''\ ... ... completed in 1.234 seconds. ... ... ... completed in 123.234 seconds. ... ... ... completed in .234 seconds. ... ... ... completed in 1.234 seconds. ... ... ''' >>> got = '''\ ... ... completed in 1.235 seconds. ... ... ... completed in 123.233 seconds. ... ... ... completed in .231 seconds. ... ... ... completed in 1.23 seconds. ... ... ''' We may wish to consider these two strings to match, even though they differ in actual addresses and times. The default output checker will consider them different: >>> doctest.OutputChecker().check_output(want, got, 0) False We'll use the RENormalizing to normalize both the wanted and gotten strings to ignore differences in times and addresses: >>> import re >>> checker = RENormalizing([ ... (re.compile('[0-9]*[.][0-9]* seconds'), ' seconds'), ... (re.compile('at 0x[0-9a-f]+'), 'at '), ... ]) >>> checker.check_output(want, got, 0) True Usual OutputChecker options work as expected: >>> want_ellided = '''\ ... ... completed in 1.234 seconds. ... ... ... ... completed in 1.234 seconds. ... ... ''' >>> checker.check_output(want_ellided, got, 0) False >>> checker.check_output(want_ellided, got, doctest.ELLIPSIS) True When we get differencs, we output them with normalized text: >>> source = '''\ ... >>> do_something() ... ... completed in 1.234 seconds. ... ... ... ... completed in 1.234 seconds. ... ... ''' >>> example = doctest.Example(source, want_ellided) >>> print checker.output_difference(example, got, 0) Expected: > completed in seconds. ... > completed in seconds. Got: > completed in seconds. > completed in seconds. > completed in seconds. > completed in seconds. >>> print checker.output_difference(example, got, ... doctest.REPORT_NDIFF) Differences (ndiff with -expected +actual): - > - completed in seconds. - ... > completed in seconds. + > + completed in seconds. + + > + completed in seconds. + + > + completed in seconds. + If the wanted text is empty, however, we don't transform the actual output. This is usful when writing tests. We leave the expected output empty, run the test, and use the actual output as expected, after reviewing it. >>> source = '''\ ... >>> do_something() ... ''' >>> example = doctest.Example(source, '\n') >>> print checker.output_difference(example, got, 0) Expected: Got: completed in 1.235 seconds. completed in 123.233 seconds. completed in .231 seconds. completed in 1.23 seconds. If regular expressions aren't expressive enough, you can use arbitrary Python callables to transform the text. For example, suppose you want to ignore case during comparison: >>> checker = RENormalizing([ ... lambda s: s.lower(), ... lambda s: s.replace('', ''), ... ]) >>> want = '''\ ... Usage: thundermonkey [options] [url] ... ... Options: ... -h display this help message ... ''' >>> got = '''\ ... usage: thundermonkey [options] [URL] ... ... options: ... -h Display this help message ... ''' >>> checker.check_output(want, got, 0) True Suppose we forgot that must be in upper case: >>> checker = RENormalizing([ ... lambda s: s.lower(), ... ]) >>> checker.check_output(want, got, 0) False The difference would show us that: >>> source = '''\ ... >>> print_help_message() ... ''' + want >>> example = doctest.Example(source, want) >>> print checker.output_difference(example, got, ... doctest.REPORT_NDIFF), Differences (ndiff with -expected +actual): usage: thundermonkey [options] [url] - + options: -h display this help message It is possible to combine RENormalizing checkers for easy reuse: >>> address_and_time_checker = RENormalizing([ ... (re.compile('[0-9]*[.][0-9]* seconds'), ' seconds'), ... (re.compile('at 0x[0-9a-f]+'), 'at '), ... ]) >>> lowercase_checker = RENormalizing([ ... lambda s: s.lower(), ... ]) >>> combined_checker = address_and_time_checker + lowercase_checker >>> len(combined_checker.transformers) 3 Combining a checker with something else does not work: >>> lowercase_checker + 5 Traceback (most recent call last): ...

Only directories selected for testing should report coverage. The test runner provides a custom implementation of the relevant API. The ``TestIgnore`` class, the class managing the ignoring, is initialized by passing the command line options. It uses the options to determine the directories that should be covered. >>> class FauxOptions(object): ... package = None ... test_path = [('/myproject/src/blah/foo', ''), ...

Those should *always* be ignored: >>> ignore.names('/myproject/src/blah/hello.txt', '') True To make this check fast, the class implements a cache. In an early implementation, the result was cached by the module name, which was a problem, since a lot of modules carry the same name (not the Python dotted name here!). So just because a module has the same name in an ignored and tested directory, does not mean it is always ignored: >>> ignore.names('/myproject/src/blah/module.py', 'module') True >>> ignore.names('/myproject/src/blah/foo/module.py', 'module') False zope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/tb_format.py0000644000175000017500000000315712214017655026062 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

However, if you want to ensure that your tests are well isolated then running them in a varying order can be helpful. (Proper isolation meaning your tests don't depend on each others outcomes or side effects and thus the setup and tear down methods are written properly.) The ``--shuffle`` option tells the test runner to shuffle the list of tests before running them: >>> import os.path, sys >>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex') >>> defaults = [ ... '--path', directory_with_tests, ... '--tests-pattern', '^sampletestsf?$', ... ] >>> from zope.testing import testrunner >>> default_argv = 'test -u -m sample1 -t test_y0 --list-tests ' Running shuffled tests ---------------------- When specifying the ``--shuffle`` option tests are ordered differently each time you run the tests: >>> argv = (default_argv + '--shuffle').split() >>> testrunner.run_internal(defaults, argv) Tests were shuffled using seed number ... Listing zope.testing.testrunner.layer.UnitTests tests: ... False Note: The runner prints out a new piece of information which is the seed number used to generate the shuffled list of tests. This seed number can later be used to re-run the tests in exactly the same order to support debugging. Specifying a seed number to control tests shuffling --------------------------------------------------- Along with the ``--shuffle`` option comes the ``--shuffle-seed`` option which takes a seed number as an argument. If you want to reproduce test failures that happened during a randomly shuffled test run then simply write down the seed number that was printed out and run it again using the ``--shuffle-seed`` option. The order is guaranteed to be the same. For example, using the seed number 0 will give us the following, stable, list of tests: >>> argv = (default_argv + '--shuffle --shuffle-seed 0').split() >>> testrunner.run_internal(defaults, argv) Tests were shuffled using seed number 0. Listing zope.testing.testrunner.layer.UnitTests tests: test_y0 (sample1.sampletestsf.TestA) test_y0 (sample1.sampletests.test_one) test_y0 (sample1.sampletests.test1.TestA) test_y0 (sample1.sampletestsf) test_y0 (sample1.sampletests.test_one.TestA) test_y0 (sample1.sample13.sampletests) test_y0 (sample1.sample13.sampletests.TestA) test_y0 (sample1.sample11.sampletests) test_y0 (sample1.sample11.sampletests.TestA) test_y0 (sample1.sampletests.test1) False >>> testrunner.run_internal(defaults, argv) Tests were shuffled using seed number 0.

It may also provide setup and teardown methods used to reset the environment provided by the layer between each test. Layers are generally implemented as classes using class methods. >>> class BaseLayer: ... def setUp(cls): ... log('BaseLayer.setUp') ... setUp = classmethod(setUp) ... ... def tearDown(cls): ... log('BaseLayer.tearDown') ... tearDown = classmethod(tearDown) ... ... def testSetUp(cls): ... log('BaseLayer.testSetUp') ... testSetUp = classmethod(testSetUp) ... ... def testTearDown(cls): ... log('BaseLayer.testTearDown') ... testTearDown = classmethod(testTearDown) ... Layers can extend other layers. Note that they do not explicitly invoke the setup and teardown methods of other layers - the test runner does this for us in order to minimize the number of invocations. >>> class TopLayer(BaseLayer): ... def setUp(cls): ... log('TopLayer.setUp') ... setUp = classmethod(setUp) ... ... def tearDown(cls): ... log('TopLayer.tearDown') ... tearDown = classmethod(tearDown) ... ... def testSetUp(cls): ... log('TopLayer.testSetUp') ... testSetUp = classmethod(testSetUp) ... ... def testTearDown(cls): ... log('TopLayer.testTearDown') ... testTearDown = classmethod(testTearDown) ... Tests or test suites specify what layer they need by storing a reference in the 'layer' attribute. >>> import unittest >>> class TestSpecifyingBaseLayer(unittest.TestCase): ... 'This TestCase explicitly specifies its layer' ... layer = BaseLayer ... name = 'TestSpecifyingBaseLayer' # For testing only ... ... def setUp(self): ... log('TestSpecifyingBaseLayer.setUp') ... ... def tearDown(self): ... log('TestSpecifyingBaseLayer.tearDown') ... ... def test1(self): ... log('TestSpecifyingBaseLayer.test1') ... ... def test2(self): ... log('TestSpecifyingBaseLayer.test2') ... >>> class TestSpecifyingNoLayer(unittest.TestCase): ...

Create a TestSuite containing two test suites, one for each of TestSpecifyingBaseLayer and TestSpecifyingNoLayer. >>> umbrella_suite = unittest.TestSuite() >>> umbrella_suite.addTest(unittest.makeSuite(TestSpecifyingBaseLayer)) >>> no_layer_suite = unittest.makeSuite(TestSpecifyingNoLayer) >>> umbrella_suite.addTest(no_layer_suite) Before we can run the tests, we need to setup some helpers. >>> from zope.testing.testrunner import options >>> from zope.testing.loggingsupport import InstalledHandler >>> import logging >>> log_handler = InstalledHandler('zope.testing.tests') >>> def log(msg): ... logging.getLogger('zope.testing.tests').info(msg) >>> def fresh_options(): ... opts = options.get_options(['--test-filter', '.*']) ... opts.resume_layer = None ... opts.resume_number = 0 ... return opts Now we run the tests. Note that the BaseLayer was not setup when the TestSpecifyingNoLayer was run and setup/torn down around the TestSpecifyingBaseLayer tests. >>> from zope.testing.testrunner.runner import Runner >>> runner = Runner(options=fresh_options(), args=[], found_suites=[umbrella_suite]) >>> succeeded = runner.run() Running BaseLayer tests: Set up BaseLayer in N.NNN seconds. Ran 2 tests with 0 failures and 0 errors in N.NNN seconds. Running zope.testing.testrunner.layer.UnitTests tests: Tear down BaseLayer in N.NNN seconds. Set up zope.testing.testrunner.layer.UnitTests in N.NNN seconds. Ran 2 tests with 0 failures and 0 errors in N.NNN seconds. Tearing down left over layers: Tear down zope.testing.testrunner.layer.UnitTests in N.NNN seconds. Total: 4 tests, 0 failures, 0 errors in N.NNN seconds. Now lets specify a layer in the suite containing TestSpecifyingNoLayer and run the tests again. This demonstrates the other method of specifying a layer. This is generally how you specify what layer doctests need. >>> no_layer_suite.layer = BaseLayer >>> runner = Runner(options=fresh_options(), args=[], found_suites=[umbrella_suite]) >>> succeeded = runner.run() Running BaseLayer tests: Set up BaseLayer in N.NNN seconds. Ran 4 tests with 0 failures and 0 errors in N.NNN seconds. Tearing down left over layers: Tear down BaseLayer in N.NNN seconds. Clear our logged output, as we want to inspect it shortly. >>> log_handler.clear() Now lets also specify a layer in the TestSpecifyingNoLayer class and rerun the tests. This demonstrates that the most specific layer is used. It also shows the behavior of nested layers - because TopLayer extends BaseLayer, both the BaseLayer and TopLayer environments are setup when the TestSpecifyingNoLayer tests are run. >>> TestSpecifyingNoLayer.layer = TopLayer >>> runner = Runner(options=fresh_options(), args=[], found_suites=[umbrella_suite]) >>> succeeded = runner.run() Running BaseLayer tests: Set up BaseLayer in N.NNN seconds.

Tearing down left over layers: Tear down TopLayer in N.NNN seconds. Tear down BaseLayer in N.NNN seconds. Total: 4 tests, 0 failures, 0 errors in N.NNN seconds. If we inspect our trace of what methods got called in what order, we can see that the layer setup and teardown methods only got called once. We can also see that the layer's test setup and teardown methods got called for each test using that layer in the right order. >>> def report(): ... for record in log_handler.records: ... print record.getMessage() >>> report() BaseLayer.setUp BaseLayer.testSetUp TestSpecifyingBaseLayer.setUp TestSpecifyingBaseLayer.test1 TestSpecifyingBaseLayer.tearDown BaseLayer.testTearDown BaseLayer.testSetUp TestSpecifyingBaseLayer.setUp TestSpecifyingBaseLayer.test2 TestSpecifyingBaseLayer.tearDown BaseLayer.testTearDown TopLayer.setUp BaseLayer.testSetUp TopLayer.testSetUp TestSpecifyingNoLayer.setUp TestSpecifyingNoLayer.test TestSpecifyingNoLayer.tearDown TopLayer.testTearDown BaseLayer.testTearDown BaseLayer.testSetUp TopLayer.testSetUp TestSpecifyingNoLayer.setUp TestSpecifyingNoLayer.test TestSpecifyingNoLayer.tearDown TopLayer.testTearDown BaseLayer.testTearDown TopLayer.tearDown BaseLayer.tearDown Now lets stack a few more layers to ensure that our setUp and tearDown methods are called in the correct order. >>> from zope.testing.testrunner.find import name_from_layer >>> class A(object): ... def setUp(cls): ... log('%s.setUp' % name_from_layer(cls)) ... setUp = classmethod(setUp) ... ... def tearDown(cls): ... log('%s.tearDown' % name_from_layer(cls)) ... tearDown = classmethod(tearDown) ... ... def testSetUp(cls): ... log('%s.testSetUp' % name_from_layer(cls)) ... testSetUp = classmethod(testSetUp) ... ... def testTearDown(cls): ... log('%s.testTearDown' % name_from_layer(cls)) ... testTearDown = classmethod(testTearDown) ... >>> class B(A): pass >>> class C(B): pass >>> class D(A): pass >>> class E(D): pass >>> class F(C,E): pass >>> class DeepTest(unittest.TestCase): ... layer = F ... def test(self): ... pass >>> suite = unittest.makeSuite(DeepTest) >>> log_handler.clear() >>> runner = Runner(options=fresh_options(), args=[], found_suites=[suite]) >>> succeeded = runner.run() Running F tests: Set up A in N.NNN seconds.

Let's look first at using `pdb.set_trace`. To demonstrate this, we'll provide input via helper Input objects: >>> class Input: ... def __init__(self, src): ... self.lines = src.split('\n') ... def readline(self): ... line = self.lines.pop(0) ... print line ... return line+'\n' If a test or code called by a test calls pdb.set_trace, then the runner will enter pdb at that point: >>> import os.path, sys >>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex') >>> from zope.testing import testrunner >>> defaults = [ ... '--path', directory_with_tests, ... '--tests-pattern', '^sampletestsf?$', ... ] >>> real_stdin = sys.stdin >>> if sys.version_info[:2] == (2, 3): ... sys.stdin = Input('n\np x\nc') ... else: ... sys.stdin = Input('p x\nc') >>> sys.argv = ('test -ssample3 --tests-pattern ^sampletests_d$' ...

False Note that, prior to Python 2.4, calling pdb.set_trace caused pdb to break in the pdb.set_trace function. It was necessary to use 'next' or 'up' to get to the application code that called pdb.set_trace. In Python 2.4, pdb.set_trace causes pdb to stop right after the call to pdb.set_trace. You can also do post-mortem debugging, using the --post-mortem (-D) option: >>> sys.stdin = Input('p x\nc') >>> sys.argv = ('test -ssample3 --tests-pattern ^sampletests_d$' ... ' -t post_mortem1 -D').split() >>> try: testrunner.run_internal(defaults) ... finally: sys.stdin = real_stdin ... # doctest: +NORMALIZE_WHITESPACE +REPORT_NDIFF Running zope.testing.testrunner.layer.UnitTests tests: ...

See http://www.voidspace.org.uk/python/articles/unittest2.shtml#more-skipping Although testrunner is currently not able to hande unexpected successes correctly at least it does not report them as successes. This document has some edge-case examples to test various aspects of the test runner. Separating Python path and test directories ------------------------------------------- The --path option defines a directory to be searched for tests *and* a directory to be added to Python's search path. The --test-path option can be used when you want to set a test search path without also affecting the Python path: >>> import os, sys >>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex-719369') >>> from zope.testing import testrunner >>> defaults = [ ...

If no such function is present, testrunner will use all classes in the module that inherit from unittest.TestCase as tests: >>> import os, sys >>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex') >>> from zope.testing import testrunner >>> defaults = [ ...

Its primary feature is that it *finds* tests by searching directory trees. It doesn't require the manual concatenation of specific test suites. It is highly customizable and should be usable with any project. In addition to finding and running tests, it provides the following additional features: - Test filtering using specifications of: o test packages within a larger tree o regular expression patterns for test modules o regular expression patterns for individual tests - Organization of tests into levels and layers Sometimes, tests take so long to run that you don't want to run them on every run of the test runner. Tests can be defined at different levels. The test runner can be configured to only run tests at a specific level or below by default. Command-line options can be used to specify a minimum level to use for a specific run, or to run all tests. Individual tests or test suites can specify their level via a 'level' attribute. where levels are integers increasing from 1. Most tests are unit tests. They don't depend on other facilities, or set up whatever dependencies they have. For larger applications, it's useful to specify common facilities that a large number of tests share. Making each test set up and and tear down these facilities is both ineffecient and inconvenient. For this reason, we've introduced the concept of layers, based on the idea of layered application architectures. Software build for a layer should be able to depend on the facilities of lower layers already being set up. For example, Zope defines a component architecture. Much Zope software depends on that architecture. We should be able to treat the component architecture as a layer that we set up once and reuse. Similarly, Zope application software should be able to depend on the Zope application server without having to set it up in each test. The test runner introduces test layers, which are objects that can set up environments for tests within the layers to use. A layer is set up before running the tests in it. Individual tests or test suites can define a layer by defining a `layer` attribute, which is a test layer. - Reporting - progress meter - summaries of tests run - Analysis of test execution - post-mortem debugging of test failures - memory leaks - code coverage - source analysis using pychecker - memory errors - execution times - profiling zope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/__init__.py0000644000175000017500000000424212214017655025640 0ustar arnauarnau############################################################################## # # Copyright (c) 2004-2006 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

Make sure this works now:: >>> get_unicode() u'foo \u2014 bar' >>> print get_unicode() foo — bar Get some normal output as well:: >>> 'xyz' 123 zope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex/sample1/0000755000175000017500000000000012214017655027712 5ustar arnauarnauzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex/sample1/sample11/0000755000175000017500000000000012214017655031335 5ustar arnauarnau././@LongLink0000000000000000000000000000015400000000000011565 Lustar rootrootzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex/sample1/sample11/__init__.pyzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex/sample1/sample11/__in0000644000175000017500000000000212214017655032154 0ustar arnauarnau# ././@LongLink0000000000000000000000000000015700000000000011570 Lustar rootrootzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex/sample1/sample11/sampletests.pyzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex/sample1/sample11/samp0000644000175000017500000000530312214017655032221 0ustar arnauarnau############################################################################## # # Copyright (c) 2003 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.0 (ZPL).

Prior to the change that this tests, output from within a test layer in a subprocess would be buffered. This could wreak havoc on supervising processes (or human) that would kill a test run if no output was seen for some period of time. First, we wrap stdout with an object that instruments it. It notes the time at which a given line was written. >>> import os, sys, datetime >>> class RecordingStreamWrapper: ... def __init__(self, wrapped): ... self.record = [] ... self.wrapped = wrapped ... def write(self, out): ... self.record.append((out, datetime.datetime.now())) ... self.wrapped.write(out) ... def flush(self): ... self.wrapped.flush() ... >>> sys.stdout = RecordingStreamWrapper(sys.stdout) Now we actually call our test. If you open the file to which we are referring here (zope/testing/testrunner-ex/sampletests_buffering.py) you will see two test suites, each with its own layer that does not know how to tear down. This forces the second suite to be run in a subprocess. That second suite has two tests. Both sleep for half a second each. >>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex') >>> from zope.testing import testrunner >>> defaults = [ ... '--path', directory_with_tests, ... ] >>> argv = [sys.argv[0], ... '-vv', '--tests-pattern', '^sampletests_buffering.*'] >>> try: ... testrunner.run_internal(defaults, argv) ... record = sys.stdout.record ... finally: ... sys.stdout = sys.stdout.wrapped ... Running tests at level 1 Running sampletests_buffering.Layer1 tests: Set up sampletests_buffering.Layer1 in N.NNN seconds. Running: test_something (sampletests_buffering.TestSomething1) Ran 1 tests with 0 failures and 0 errors in N.NNN seconds.

Tear down sampletests_buffering.Layer2 ... not supported Total: 3 tests, 0 failures, 0 errors in N.NNN seconds. False Now we actually check the results we care about. We should see that there are two pauses of about half a second, one around the first test and one around the second. Before the change that this test verifies, there was a single pause of more than a second after the second suite ran. >>> def assert_progressive_output(): ... pause = datetime.timedelta(seconds=0.3) ... last_line, last_time = record.pop(0) ... print '---' ... for line, time in record: ... if time-last_time >= pause: ... # We paused! ... print 'PAUSE FOUND BETWEEN THESE LINES:' ... print ''.join([last_line, line, '-'*70]) ... last_line, last_time = line, time >>> assert_progressive_output() # doctest: +ELLIPSIS ---...

Because this is a test based on timing, it may be somewhat fragile. However, on a relatively slow machine, this timing works out fine; I'm hopeful that this test will not be a source of spurious errors. If it is, we will have to readdress. Now let's do the same thing, but with multiple processes at once. We'll get a different result that has similar characteristics. >>> sys.stdout = RecordingStreamWrapper(sys.stdout) >>> argv.extend(['-j', '2']) >>> try: ... testrunner.run_internal(defaults, argv) ... record = sys.stdout.record ... finally: ... sys.stdout = sys.stdout.wrapped ...

False Notice that, with a -vv (or greater) verbosity, the parallel test run includes a progress report to keep track of tests run in the various layers. Because the actual results are saved to be displayed assembled in the original test order, the progress report shows up before we are given the news that the testrunner is starting Layer2. This is counterintuitive, but lets us keep the primary reporting information for the given layer in one location, while also giving us progress reports that can be used for keepalive analysis by a human or automated agent. In particular for the second point, notice below that, as before, the progress output is not buffered. >>> def assert_progressive_output(): ... pause = datetime.timedelta(seconds=0.3) ... last_line, last_time = record.pop(0) ... print '---' ... for line, time in record: ... if time-last_time >= pause: ... # We paused! ... print 'PAUSE FOUND BETWEEN THIS OUTPUT:' ... print '\n'.join([last_line, line, '-'*70]) ... last_line, last_time = line, time >>> assert_progressive_output() # doctest: +ELLIPSIS ---...

The --gc option can be used for this purpose. If you think you are getting a test failure due to a garbage collection problem, you can try disabling garbage collection by using the --gc option with a value of zero. >>> import os.path, sys >>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex') >>> defaults = ['--path', directory_with_tests] >>> from zope.testing import testrunner >>> sys.argv = 'test --tests-pattern ^gc0$ --gc 0 -vv'.split() >>> _ = testrunner.run_internal(defaults) Cyclic garbage collection is disabled.

Alternatively, if you think you are having a garbage collection related problem, you can cause garbage collection to happen more often by providing a low threshold: >>> sys.argv = 'test --tests-pattern ^gc1$ --gc 1 -vv'.split() >>> _ = testrunner.run_internal(defaults) Cyclic garbage collection threshold set to: (1,) Running tests at level 1 Running zope.testing.testrunner.layer.UnitTests tests: Set up zope.testing.testrunner.layer.UnitTests in N.NNN seconds.

The test runner is used by providing scripts that import and invoke the `run` method from the module. The `testrunner` module is controlled via command-line options. Test scripts supply base and default options by supplying a list of default command-line options that are processed before the user-supplied command-line options are provided. Typically, a test script does 2 things: - Adds the directory containing the zope package to the Python path. - Calls the test runner with default arguments and arguments supplied to the script. Normally, it just passes default/setup arguments. The test runner uses `sys.argv` to get the user's input. This testrunner_ex subdirectory contains a number of sample packages with tests. Let's run the tests found here. First though, we'll set up our default options: >>> import os.path >>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex') >>> defaults = [ ... '--path', directory_with_tests, ... '--tests-pattern', '^sampletestsf?$', ... ] The default options are used by a script to customize the test runner for a particular application. In this case, we use two options: path Set the path where the test runner should look for tests. This path is also added to the Python path. tests-pattern Tell the test runner how to recognize modules or packages containing tests. Now, if we run the tests, without any other options: >>> from zope.testing import testrunner >>> import sys >>> sys.argv = ['test'] >>> testrunner.run_internal(defaults) Running samplelayers.Layer1 tests: Set up samplelayers.Layer1 in N.NNN seconds. Ran 9 tests with 0 failures and 0 errors in N.NNN seconds. Running samplelayers.Layer11 tests: Set up samplelayers.Layer11 in N.NNN seconds. Ran 34 tests with 0 failures and 0 errors in N.NNN seconds. Running samplelayers.Layer111 tests: Set up samplelayers.Layerx in N.NNN seconds. Set up samplelayers.Layer111 in N.NNN seconds. Ran 34 tests with 0 failures and 0 errors in N.NNN seconds. Running samplelayers.Layer112 tests: Tear down samplelayers.Layer111 in N.NNN seconds. Set up samplelayers.Layer112 in N.NNN seconds. Ran 34 tests with 0 failures and 0 errors in N.NNN seconds. Running samplelayers.Layer12 tests: Tear down samplelayers.Layer112 in N.NNN seconds. Tear down samplelayers.Layerx in N.NNN seconds. Tear down samplelayers.Layer11 in N.NNN seconds. Set up samplelayers.Layer12 in N.NNN seconds. Ran 34 tests with 0 failures and 0 errors in N.NNN seconds. Running samplelayers.Layer121 tests: Set up samplelayers.Layer121 in N.NNN seconds. Ran 34 tests with 0 failures and 0 errors in N.NNN seconds. Running samplelayers.Layer122 tests: Tear down samplelayers.Layer121 in N.NNN seconds. Set up samplelayers.Layer122 in N.NNN seconds. Ran 34 tests with 0 failures and 0 errors in N.NNN seconds. Running zope.testing.testrunner.layer.UnitTests tests: Tear down samplelayers.Layer122 in N.NNN seconds. Tear down samplelayers.Layer12 in N.NNN seconds. Tear down samplelayers.Layer1 in N.NNN seconds. Set up zope.testing.testrunner.layer.UnitTests in N.NNN seconds. Ran 192 tests with 0 failures and 0 errors in N.NNN seconds. Tearing down left over layers: Tear down zope.testing.testrunner.layer.UnitTests in N.NNN seconds. Total: 405 tests, 0 failures, 0 errors in N.NNN seconds. False we see the normal testrunner output, which summarizes the tests run for each layer. For each layer, we see what layers had to be torn down or set up to run the layer and we see the number of tests run, with results. The test runner returns a boolean indicating whether there were errors. In this example, there were no errors, so it returned False. (Of course, the times shown in these examples are just examples. Times will vary depending on system speed.) zope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/0000755000175000017500000000000012214017655027122 5ustar arnauarnauzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/0000755000175000017500000000000012214017655030047 5ustar arnauarnau././@LongLink0000000000000000000000000000016200000000000011564 Lustar rootrootzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/foo.bar-1.2-py2.5.egg/zope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/foo.bar-10000755000175000017500000000000012214017655031454 5ustar arnauarnau././@LongLink0000000000000000000000000000017100000000000011564 Lustar rootrootzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/foo.bar-1.2-py2.5.egg/test.pyzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/foo.bar-10000644000175000017500000000000012214017655031444 0ustar arnauarnau././@LongLink0000000000000000000000000000016600000000000011570 Lustar rootrootzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/foo.bar-1.2-py2.5.egg/foo/zope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/foo.bar-10000755000175000017500000000000012214017655031454 5ustar arnauarnau././@LongLink0000000000000000000000000000017200000000000011565 Lustar rootrootzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/foo.bar-1.2-py2.5.egg/foo/bar/zope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/foo.bar-10000755000175000017500000000000012214017655031454 5ustar arnauarnau././@LongLink0000000000000000000000000000020500000000000011562 Lustar rootrootzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/foo.bar-1.2-py2.5.egg/foo/bar/__init__.pyzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/foo.bar-10000644000175000017500000000000012214017655031444 0ustar arnauarnau././@LongLink0000000000000000000000000000020200000000000011557 Lustar rootrootzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/foo.bar-1.2-py2.5.egg/foo/bar/tests.pyzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/foo.bar-10000644000175000017500000000000012214017655031444 0ustar arnauarnau././@LongLink0000000000000000000000000000020100000000000011556 Lustar rootrootzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/foo.bar-1.2-py2.5.egg/foo/__init__.pyzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-ex-251759/eggs/foo.bar-10000644000175000017500000000000012214017655031444 0ustar arnauarnauzope2.13-2.13.21/source/zope.testing/src/zope/testing/testrunner/testrunner-progress.txt0000644000175000017500000005110112214017655030337 0ustar arnauarnauTest Progress ============= If the --progress (-p) option is used, progress information is printed and a carriage return (rather than a new-line) is printed between detail lines.

Here, the actual output uses the word "and" rather than the word "an", but it's a bit hard to pick this out. We can use the various diff outputs to see this better. We could modify the test to ask for diff output, but it's easier to use one of the diff options. The --ndiff option requests a diff using Python's ndiff utility. This is the only method that marks differences within lines as well as across lines. For example, if a line of expected output contains digit 1 where actual output contains letter l, a line is inserted with a caret marking the mismatching column positions. >>> sys.argv = 'test --tests-pattern ^pledge$ --ndiff'.split() >>> _ = testrunner.run_internal(defaults) Running zope.testing.testrunner.layer.UnitTests tests: Set up zope.testing.testrunner.layer.UnitTests in N.NNN seconds.

The testrunner needs to be given extra information about this sort of situation. Let's look at an example. The testrunner-ex-knit-lib directory is a directory that we want to add to the Python path, but that we don't want to search for tests. It has a sample4 package and a products subpackage. The products subpackage adds the testrunner-ex-knit-products to it's __path__. We want to run tests from the testrunner-ex-knit-products directory. When we import these tests, we need to import them from the sample4.products package. We can't use the --path option to name testrunner-ex-knit-products. It isn't enough to add the containing directory to the test path because then we wouldn't be able to determine the package name properly. We might be able to use the --package option to run the tests from the sample4/products package, but we want to run tests in testrunner-ex that aren't in this package. We can use the --package-path option in this case. The --package-path option is like the --test-path option in that it defines a path to be searched for tests without affecting the python path. It differs in that it supplied a package name that is added a profex when importing any modules found. The --package-path option takes *two* arguments, a package name and file path. >>> import os.path, sys >>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex') >>> sys.path.append(os.path.join(this_directory, 'testrunner-ex-pp-lib')) >>> defaults = [ ...

We have a very simple directory tree, under ``usecompiled/``, to test this. Because we're going to delete its .py files, we want to work in a copy of that: >>> import os.path, shutil, sys, tempfile >>> directory_with_tests = tempfile.mkdtemp() >>> NEWNAME = "unlikely_package_name" >>> src = os.path.join(this_directory, 'testrunner-ex', 'usecompiled') >>> os.path.isdir(src) True >>> dst = os.path.join(directory_with_tests, NEWNAME) >>> os.path.isdir(dst) False Have to use our own copying code, to avoid copying read-only SVN files that can't be deleted later. >>> n = len(src) + 1 >>> for root, dirs, files in os.walk(src): ... dirs[:] = [d for d in dirs if d == "package"] # prune cruft ... os.mkdir(os.path.join(dst, root[n:])) ... for f in files: ... shutil.copy(os.path.join(root, f), ... os.path.join(dst, root[n:], f)) Now run the tests in the copy: >>> from zope.testing import testrunner >>> mydefaults = [ ... '--path', directory_with_tests, ... '--tests-pattern', '^compiletest$', ... '--package', NEWNAME, ... '-vv', ... ] >>> sys.argv = ['test'] >>> testrunner.run_internal(mydefaults) Running tests at level 1 Running zope.testing.testrunner.layer.UnitTests tests: Set up zope.testing.testrunner.layer.UnitTests in N.NNN seconds.

Tearing down left over layers: Tear down zope.testing.testrunner.layer.UnitTests in N.NNN seconds. False If we delete the source files, it's normally a disaster: the test runner doesn't believe any test files, or even packages, exist. Note that we pass ``--keepbytecode`` this time, because otherwise the test runner would delete the compiled Python files too: >>> for root, dirs, files in os.walk(dst): ... for f in files: ... if f.endswith(".py"): ... os.remove(os.path.join(root, f)) >>> testrunner.run_internal(mydefaults, ["test", "--keepbytecode"]) Running tests at level 1 Total: 0 tests, 0 failures, 0 errors in N.NNN seconds. False Finally, passing ``--usecompiled`` asks the test runner to treat .pyc and .pyo files as adequate replacements for .py files. Note that the output is the same as when running with .py source above. The absence of "removing stale bytecode ..." messages shows that ``--usecompiled`` also implies ``--keepbytecode``: >>> testrunner.run_internal(mydefaults, ["test", "--usecompiled"]) Running tests at level 1 Running zope.testing.testrunner.layer.UnitTests tests: Set up zope.testing.testrunner.layer.UnitTests in N.NNN seconds.

Tear down samplelayers.Layer1 in 0.000 seconds. Total: 68 tests, 0 failures, 0 errors in N.NNN seconds. Each layer is repeated the requested number of times. For each iteration after the first, the system refcount and change in system refcount is shown. The system refcount is the total of all refcount in the system. When a refcount on any object is changed, the system refcount is changed by the same amount. Tests that don't leak show zero changes in systen refcount. Let's look at an example test that leaks: >>> sys.argv = 'test --tests-pattern leak -N4 -r'.split() >>> _ = testrunner.run_internal(defaults) Running zope.testing.testrunner.layer.UnitTests tests:... Iteration 1 Ran 1 tests with 0 failures and 0 errors in 0.000 seconds.

Here we see that the system refcount is increating.

It is instructive to analyze the results in some detail. The test being run was designed to intentionally leak: class ClassicLeakable: def __init__(self): self.x = 'x' class Leakable(object): def __init__(self): self.x = 'x' leaked = [] class TestSomething(unittest.TestCase): def testleak(self): leaked.append((ClassicLeakable(), Leakable(), time.time())) Let's go through this by type. float, leak.ClassicLeakable, leak.Leakable, and tuple We leak one of these every time. This is to be expected because we are adding one of these to the list every time. str We don't leak any instances, but we leak 4 references. These are due to the instance attributes avd values. dict We leak 2 of these, one for each ClassicLeakable and Leakable instance. classobj We increase the number of classobj instance references by one each time because each ClassicLeakable instance has a reference to its class. This instances increases the references in it's class, which increases the total number of references to classic classes (clasobj instances). type For most interations, we increase the number of type references by one for the same reason we increase the number of clasobj references by one. The increase of the number of type references by 3 in the second iteration is puzzling, but illustrates that this sort of data is often puzzling. int The change in the number of int instances and references in this example is a side effect of the statistics being gathered. Lots of integers are created to keep the memory statistics used here. The summary statistics include the sum of the detail refcounts. (Note that this sum is less than the system refcount. This is because the detailed analysis doesn't inspect every object. Not all objects in the system are returned by sys.getobjects.) zope2.13-2.13.21/source/zope.testing/src/zope/testing/cleanup.py0000644000175000017500000000346712214017655023327 0ustar arnauarnau############################################################################## # # Copyright (c) 2001, 2002 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

    Almost all Zope objects can be owned. When you create an object you become its owner. Ownership matters for method objects since it determines what roles they have when they are executed. See the Proxy Roles view of method objects for more information.

    This object is owned by &dtml-id; (&dtml-path;).unowned.


    If you have the Take Ownership permission you can take ownership of an object. Usually when taking ownership you should also take ownership of sub-objects as well.

    Also take ownership of all sub-objects

    Note: Zope can export/import objects in two different formats: a binary format (called ZEXP) and as XML. The ZEXP format is the officially supported export/import format for moving data between identical Zope installations (it is not a migration tool).

    Export object id
    		" class="form-element"/>
    Export to

     
    (unsupported, see above)

    You may import Zope objects which have been previously exported to a file, by placing the file in the "import" directory of your Zope installation on the server. You should create the "import" directory in the root of your Zope installation if it does not yet exist.

    Note that by default, you will become the owner of the objects that you are importing. If you wish the imported objects to retain their existing ownership information, select "retain existing ownership information".

    This application's transactional feature allows you to easily undo changes made to the application's settings or data. You can revert the application to a "snapshot" of its state at a previous point in time.

    Select one or more transactions below and then click on the "Undo" button to undo those transactions. Note that even though a transaction is shown below, you may not be able to undo it if later transactions modified objects that were modified by a selected transaction.

    Profiling is not currently enabled or there is not yet any profiling data to report. To enable profiling, restart the Zope process with the configuration setting 'publisher-profile-file' defined. The value of this variable should be the full system path to a file that will be used to dump a profile report when the process restarts or exits.

    You have not created any users in this Zope instance. In order to log in and manage this Zope instance, you'll need to add an administrative user account.

    You can create an administrative user account via the "zopectl adduser" command from a shell. Note: You'll need to shut Zope itself down before "zopectl adduser" will work. Restart Zope after executing this command in order to log in.

    Welcome to Zope, a high-performance object-oriented platform for building dynamic Web applications. Here are some quick pointers to get you started:

    • Read The Fine Manual. This document guides you through the whole process of learning Zope, from logging in for the first time to creating your own web applications.

    • Go to the main Documentation Overview on Zope.org. Here you will find pointers to official and community contributed documentation.

    • Look at the various Mailing Lists about Zope. The Mailing Lists are where you can get quick, accurate, friendly help from a large community of Zope users from around the world.

    • Go directly to the Zope Management Interface if you'd like to start working with Zope right away.

    &dtml-form_title;

    The refresh function, designed to ease the development of Zope products, is not currently enabled for this product. To make it available, put a file named "refresh.txt" in the &dtml-id; product directory. Please note that not all products are compatible with the refresh function.

    An exception occurred during the last refresh.
    Exception type: &dtml-error_type;
    Exception value: &dtml-error_value; 

    &dtml-error_tb;

    Important information about refreshing this product:

    Auto refresh is enabled. Zope will repeatedly scan for changes to the Python modules that make up this product and execute a refresh when needed. Although auto refresh is enabled, Zope is not in development mode so auto refresh is not available. Use the "-D" argument when starting Zope to enable development mode. Auto refresh is disabled. Enable auto refresh to cause Zope to frequently scan this product for changes. Note that auto refresh can slow down Zope considerably if enabled for more than a few products.
    Auto refresh mode  

    Select dependent auto-refreshable products to be refreshed simultaneously.

    Refreshable product modules:

FAIL (No value given for property {http://webdav.org/neon/litmus/}high-unicode) This is because test 17 fails to set a value. 'locks' tests: 15. cond_put.............. SKIPPED Zope does not appear to send an Etag in normal responses, which this test seems to require as a precondition for execution. See http://www.mnot.net/cache_docs/ for more information about Etags. These tests appear to be skipped for the same reason: 16. fail_cond_put......... SKIPPED 19. complex_cond_put...... SKIPPED 20. fail_complex_cond_put. SKIPPED Zope's webdav package has an webdav.EtagSupport.EtagSupport class which is inherited by the webdav.Lockable.LockableItem class, which is in turn inherited by the webdav.Resource.Resource class, which is in turn inherited by OFS.SimpleItem.SimpleItem (upon which almost all Zope content is based), so potentially all Zope content can reasonably easily generate meaningful ETags in responses. Finding out why it's not generating them appears to be an archaeology exercise. 18. cond_put_corrupt_token FAIL (conditional PUT with invalid lock-token should fail: 204 No Content) I (chrism) haven't been able to fix this without breaking 32. lock_collection, which is a more important interaction.

FAIL (LOCK on `/litmus/lockme': 403 Forbidden) Zope does not support locking resources with lockscope 'shared' (only exclusive locks are supported for any kind of Zope resource). Litmus could probably do a PROPFIND on the /litmus/lockme resource and check the lockscope in the response before declaring this a failure (class 2 DAV servers are not required to support shared locks).

FAIL (timeout waiting for interim response) Unknown reason (not yet investigated). additional notes: litmus 0.11 times out on several of the lock tests due to some HTTP-level miscommunication between neon 0.26 and Zope (perhaps, as I've gathered on the litmus maillist, having to do with neon 0.26's expectation to use persistent connections, and perhaps due to some bug in Zope's implementation of same), and this is why litmus 0.11/neon 0.25 was used to do the testing even though litmus 11.0 was available. litmus 0.10.5 times out in a similar fashion on the "http.expect100" test but on none of the lock tests. analyses: Analysis of what happens during locks 32. lock_collection: The first request in this test set is a successful LOCK request with "Depth: infinity" to /litmus/lockcoll (an existing newly-created collection): LOCK /litmus/lockcoll/ HTTP/1.1 Depth: infinity litmus test suite Zope responds to this with a success response like this: infinity litmus test suite Second-3600 opaquelocktoken:{olt} ({olt} in the above quoted response represents an actual valid lock token, not a literal) The next request sent during this test is a conditional PUT request to /litmus/lockcoll/lockme.txt (which doesn't yet exist at the time of the request): PUT /litmus/lockcoll/lockme.txt HTTP/1.1 If: ( now) # there's time remaining def getLockType(): """ returns the lock type ('write') """ def getLockScope(): """ returns the lock scope ('exclusive') """ def asLockDiscoveryProperty(ns='d'): """ Return the lock rendered as an XML representation of a WebDAV 'lockdiscovery' property.

Objects which do not support a given operation should respond appropriately with a "405 Method Not Allowed" response.

    This item is locked by WebDAV as a Lock-Null Resource. A lock-null resource is created when a resource is locked before it is fully created, basically reserving its name. When the owner of this resource issues a command to either fill it with content, or turn it into a collection (folder), that object will replace this one.

When a signal is # registered, we simply create a global named event for that signal. The # signal can be set by any user with the correct permission opening and # setting the event. # # One event is used per signal, and the event name is based on both the # Zope process ID and the signal number. For example, assuming a process # ID of 123, a SIGINT handler would create an event called "Zope-123-2" # (as signal.SIGINT==2). The logfile reopen handler uses an event named # "Zope-123-12" (as the logfile handler uses SIGUSR2, which == 12) # The following program will send such an event: # import sys, win32event # hev = win32event.OpenEvent(win32event.EVENT_MODIFY_STATE, 0, sys.argv[1]) # win32event.SetEvent(hev) # A good way to get the PID is to read the var/*.pid file for the app. # This code is only the generic signal mechanism for Windows. # The signal handlers are still external, just like for other platforms. # NOTE: There is one huge semantic difference between these "signals" # and signals on Unix. On Windows, the signals are delivered asynchronously # to a thread inside this module. This thread calls the event handler # directly - there is no magic to switch the call back to the main thread. # If this is a problem (not currently, but likely later), one option may be # to add yet another asyncore handler - the thread in this module could # then "post" the request to the main thread via this asyncore handler. import sys, os import signal import threading import asyncore import atexit import Lifetime # As at pywin32-204, we must ensure pywintypes is the first win32 module # imported in our process, otherwise we can end up with 2 pywintypesxx.dll # instances in our process resulting in: # TypeError: The object is not a PySECURITY_ATTRIBUTES object import pywintypes # SetConsoleCtrlHandler not in early pywin32 versions - Signals.py will # catch the import error. from win32api import SetConsoleCtrlHandler import win32con import win32event import ntsecuritycon import logging logger=logging.getLogger("WinSignalHandler") # We simulate signals via win32 named events.

The Five project was a dream given form. Its goal: to use Zope 3 technologies in Zope 2.7 by creating a Zope 2 product where Zope 3 and Zope 2 could work out their differences peacefully." -- Babylon 5, creatively quoted "The Law of Fives states simply that: ALL THINGS HAPPEN IN FIVES, OR ARE DIVISIBLE BY OR ARE MULTIPLES OF FIVE, OR ARE SOMEHOW DIRECTLY OR INDIRECTLY RELATED TO FIVE. THE LAW OF FIVES IS NEVER WRONG." -- Principia Discordia What is Five? ------------- A couple of years back an attempt was made to rewrite Zope 2 from scratch and provide an upgrade path from current Zope 2 to the new version. This project used the name Zope 3. The attempt of writing a newer version of a full blown application server similar to Zope 2 failed. Instead the project generated a whole lot of underlying technologies and new concepts packaged up in reusable libraries. Five is the project that integrates those technologies and packages into Zope 2. It's name is a pun on the original naming of Zope 2 + Zope 3 = Zope 5. Among others, it allows you to use zope.interface, ZCML-based configuration, adapters, browser pages (including layers, and resources), zope.schemas, object events, as well as zope.i18n message catalogs. We've tried to keep the Five experience as close to that of the integrated Zope packages as possible, so this means that what you learn while using Five should also be applicable to the Zope packages directly. zope2.13-2.13.21/source/Zope2/src/Products/Five/doc/0000755000175000017500000000000012214017421020460 5ustar arnauarnauzope2.13-2.13.21/source/Zope2/src/Products/Five/doc/manual.txt0000644000175000017500000001560212214017421022502 0ustar arnauarnau=========== Five Manual =========== Zope interfaces --------------- Interfaces? =========== An interface is simply a description of what an object provides to the world, i.e. its public attribute and methods. It looks very much like a class, but contains no implementation:: from zope.interface import Interface # by convention, all interfaces are prefixed with ``I`` class IElephant(Interface): """An elephant is a big object that barely fits in the cupboard. """ def getAngerLevel(): """Anger level, maximum of 100. The longer the elephant has been in the cupboard, the angrier. """ def isInCupboard(): """Returns true if the elephant is indeed in cupboard. """ def trunkSmash(target): """Smash the target with trunk. The anger level determines the force of the hit. """ def trample(target): """Trample the target. The anger level determines the rate of flattening of the target. """ A concrete class somewhere can now claim that it implements the interface (i.e. its instance will provide the interface):: class PinkElephant: # this says all instances of this class provide IElephant implements(IElephant) def getAngerLevel(self): return 0 # this elephant is peaceful def isInCupboard(self): return False # it's never in a cupboard but can be found in bottles def trunkSmash(self, target): target.tickle() def trample(self, target): target.patOnHead() Interfaces themselves are good for a number of reasons: * They provide API documentation. * They help you make explicit the design of your application, hopefully improving it. * If an object provides an interface, that object is considered to be a *component*. This means you can use Zope's component architecture with these objects. In order to use the component architecture, you'll have to make your objects provide interfaces. Sometimes, you cannot change the code of class (as you are not the maintainer), but you still want to make it implement an interface. Zope provides a ZCML directive to do this:: Adapters -------- From a Python programmer's perspective, the immediate thing that Five brings to do the table are adapters. This section goes through some demo code to explain how everything is tied together. Zope adapters depend on Zope interfaces. To create a Zope interface you need to subclass it from ``zope.interface.Interface``. Here is an example:: from zope.interface import Interface class IMyInterface(Interface): """This is an interface. """ def someMethod(): """This method does amazing stuff. """ Now to make some class declare that it implements this interface, you need to use the ``implements()`` function in the class:: from zope.interface import implements from interfaces import IMyInterface class MyClass: implements(IMyInterface) def someMethod(self): return "I am alive! Alive!" Now let's set up the interface that we are adapting to:: class INewInterface(Interface): """The interface we adapt to. """ def anotherMethod(): """This method does more stuff. """ Next we'll work on the class that implements the adapter. The requirement to make a class that is an adapter is very simple; you only need to take a context object as the constructor. The context object is the object being adapted. An example:: from zope.interface import implements from interfaces import INewInterface class MyAdapter: implements(INewInterface) def __init__(self, context): self.context = context def anotherMethod(self): return "We have adapted: %s" % self.context.someMethod() Next, we hook it all up using zcml. If the classes are in a module called ``classes.py`` and the interfaces in a module called ``interfaces.py``, we can declare ``MyAdapter`` to be an adapter for ``IMyInterface`` to ``INewInterface`` like this (in a file called ``configure.zcml``):: Zope will automatically pickup ``configure.zcml`` when it's placed in the product's directory. Any object that provides ``IMyInterface`` can now be adapted to ``INewInterface``, like this:: from classes import MyClass from interfaces import INewInterface object = MyClass() adapted = INewInterface(object) print adapted.anotherMethod() Views ----- This section will give a brief introduction on how to use the Zope view system. Zope enables you to create views for your own objects, or even built-in Zope objects, as long as two things are the case: * The object provides a Zope interface, typically through its class. * The object (typically its class) is made traversable. This allows Zope views, resources and other things to be attached to a Zope object. Typically you give your classes an interface using the ``implements`` directive in the class body:: class MyClass: implements(ISomeInterface) For existing objects that you cannot modify this is not possible. Instead, we provide a ZCML directive to accomplish this. As an example, to make Zope's ``Folder`` (and all its subclasses) implement ``IFolder`` (an interface you defined), you can do the following in ZCML:: Views in Zope are simple classes. The only requirements for a view class are: * They need an ``__init__()`` that take a context and a request attribute. Typically this comes from a base class, such as ``BrowserView``. An example of a simple view:: from zope.publisher.browser import BrowserView class SimpleFolderView(BrowserView): def eagle(self): """Test """ return "The eagle has landed: %s" % self.context.keys() Note that it is not a good idea to give a view class its own ``index_html``, as this confuses Zope's view lookup machinery. This view uses methods in Python, but you can also use other mechanisms such as ``ViewPageTemplateFile``. Finally, we need to hook up the pages through ZCML:: ``browser`` in this refers to the XML namespace for browser related things; it's ``http://namespace.zope.org/browser``. ``permission`` declares the Zope 2 permission needs in order to access this view. The file ``permissions.zcml`` in AccessControl contains a mapping of Zope 2 permissions to their zope.security names. zope2.13-2.13.21/source/Zope2/src/Products/Five/doc/features.txt0000644000175000017500000000344412214017421023044 0ustar arnauarnau============= Zope features ============= Zope features are mostly features from zope.* packages, though it has some extras and some limitations. ZCML ==== ZCML is the Zope Configuration Markup Language, an XML application. Zope code consists of a lot of components that can be plugged together using ZCML. If you put a ``site.zcml`` in the etc directory of your Zope instance, this is the root of the ZCML tree. An example of ``site.zcml`` is in ``site.zcml.in``. If you don't place a ``site.zcml``, Five falls back on ``fallback.zcml``. ZCML in Zope 2 has a special directive, ``five:loadProducts``, to load the ZCML (``meta.zcml``, ``configure.zcml``) of all installed Zope 2 products, if available. Another special directive, ``five:loadProductsOverrides`` is available to load any overriding ZCML (``overrides.zcml``) in these products. In the ``overrides.zcml`` you can override existing views or adapters, in this or in other products. Security declarations ===================== Zope 2 aims to eradicate ``declareProtected``, ``ClassSecurityInfo`` and ``initializeClass`` from your code. In order to do this, Zope 2 provides a way of declaring permissions from ZCML. To declare permissions for methods and templates on views you use the ``permission`` attribute on the ``browser:page`` directive, and specify a Zope 2 permission (given a dotted name). You can find a list of these permissions in ``permissions.zcml`` in AccessControl's permissions.zcml. The permission check takes place before the view is executed. The ``class`` directive can also be used to declare permissions on Zope 2 content classes. Note however that these permissions will be ignored by views anyway, as they are trusted -- it only serves to protect directly exposed methods on content classes (the Python scripts and the ZPublisher). zope2.13-2.13.21/source/Zope2/src/Products/Five/doc/directives.txt0000644000175000017500000000445512214017421023372 0ustar arnauarnau=================================== ZCML Directives supported by Zope 2 =================================== Zope 2 tries to use the directives from zope.* packages where possible, though does sometimes subset the possible attributes. It also introduces a few directives of its own under the ``five`` namespace. Directives are listed per namespace, in alphabetic order. zope ``http://namespaces.zope.org/zope`` ======================================== adapter ------- Hook an adapter factory to an interface. class ----- Declare interface and permissions on classes. Declares Zope 2 permissions. permission ---------- Way to make Zope 2 permissions available, ``title`` is permission name. redefinePermission ------------------ Redefine a permission in included ZCML as another one. utility ------- Declare a global utility. interface --------- Register an interface in ZCML. hook ---- Install a hook on a hookable object. browser ``http://namespaces.zope.org/browser`` ============================================== page ---- Declare a page view for an interface. Permission is a Zope 2 permission. pages ----- Declare multiple page views for an interface. Permissions are Zope 2 permissions. defaultView ----------- Declare the name of the view that should be used for the default when viewing the object; i.e. when the object is traversed to without a view. menu ---- Declare a menu menuItem, menuItems ------------------- Declare menuItems five ``http://namespaces.zope.org/five`` ======================================== loadProducts ------------ Loads ZCML in all Zope 2 products. First processes all ``meta.zcml`` files, then processes all ``configure.zcml`` files. loadProductsOverrides --------------------- Loads overriding ZCML in all products (``overrides.zcml``). sizable ------- Retrieve size information for a Zope 2 content class via a zope.size style ``ISized`` adapter. deprecatedManageAddDelete ------------------------- Specify a class that needs its old deprecated methods like ``manage_afterAdd``, ``manage_beforeDelete`` and ``manage_afterClone`` to be called. Modern classes should use event subscribers instead. pagesFromDirectory ------------------ Loads all files with .pt extension in a directory as pages. registerClass ------------- Registers Zope 2 content classes with Zope 2. zope2.13-2.13.21/source/Zope2/src/Products/Five/doc/i18n.txt0000644000175000017500000000073712214017421022007 0ustar arnauarnauInternationalization ==================== Translation ----------- To register translation domains, use the following ZCML statement:: where the 'i18n' prefix is bound to the http://namespaces.zope.org/i18n namespace identifier.

Before we can use the directives, we have to register their handlers by executing the package's meta configuration: >>> context = zcml.load_string(''' ... ... ... ... ''') Now we can register a viewlet manager: >>> context = zcml.load_string(''' ... ... ... ... ''') Let's make sure the directive has really issued a sensible adapter registration; to do that, we create some dummy content, request and view objects: >>> from Products.Five.viewlet.tests import Content >>> content = Content() >>> obj_id = self.folder._setObject('content1', Content()) >>> content = self.folder[obj_id] >>> from zope.publisher.browser import TestRequest >>> request = TestRequest() >>> from Products.Five.browser import BrowserView as View >>> view = View(content, request) Now let's lookup the manager. This particular registration is pretty boring: >>> import zope.component >>> from zope.viewlet import interfaces >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ... interfaces.IViewletManager, name='defaultmanager') >>> manager object ...> >>> interfaces.IViewletManager.providedBy(manager) True >>> manager.template is None True >>> manager.update() >>> manager.render() u'' However, this registration is not very useful, since we did specify a specific viewlet manager interface, a specific content interface, specific view or specific layer. This means that all viewlets registered will be found. The first step to effectively using the viewlet manager directive is to define a special viewlet manager interface: >>> from Products.Five.viewlet.tests import ILeftColumn Now we can register register a manager providing this interface: >>> context = zcml.load_string(''' ... ... ... ... ''') >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> ILeftColumn.providedBy(manager) True >>> manager.template is None True >>> manager.update() >>> manager.render() u'' Next let's see what happens, if we specify a template for the viewlet manager: >>> import os, tempfile >>> temp_dir = tempfile.mkdtemp() >>> leftColumnTemplate = os.path.join(temp_dir, 'leftcolumn.pt') >>> open(leftColumnTemplate, 'w').write(''' ...
    ...
    ...
    ... ''') >>> context = zcml.load_string(''' ... ... ... ... ''' %leftColumnTemplate) >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> ILeftColumn.providedBy(manager) True >>> manager.update() >>> print manager.render().strip()
    Additionally you can specify a class that will serve as a base to the default viewlet manager or be a viewlet manager in its own right. In our case we will provide a custom implementation of the ``sort()`` method, which will sort by a weight attribute in the viewlet: >>> context = zcml.load_string(''' ... ... ... ... ''' %leftColumnTemplate) >>> manager = zope.component.getMultiAdapter( ... (content, request, view), ILeftColumn, name='leftcolumn') >>> manager object ...> >>> manager.__class__.__bases__ (, ) >>> ILeftColumn.providedBy(manager) True >>> manager.update() >>> print manager.render().strip()
    Finally, if a non-existent template is specified, an error is raised: >>> context = zcml.load_string(''' ... ... ... ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 3.2-7.8 ConfigurationError: ('No such file', '...foo.pt') ========================= The ``viewlet`` Directive ========================= Now that we have a viewlet manager, we have to register some viewlets for it. The ``viewlet`` directive is similar to the ``viewletManager`` directive, except that the viewlet is also registered for a particular manager interface, as seen below: >>> weatherTemplate = os.path.join(temp_dir, 'weather.pt') >>> open(weatherTemplate, 'w').write(''' ...
    sunny
    ... ''') >>> context = zcml.load_string(''' ... ... ... ... ''' % weatherTemplate) If we look into the adapter registry, we will find the viewlet: >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='weather') >>> viewlet.render().strip() u'
    sunny
    ' >>> viewlet.extra_string_attributes u'can be specified' The manager now also gives us the output of the one and only viewlet: >>> manager.update() >>> print manager.render().strip()
    sunny
    Let's now ensure that we can also specify a viewlet class: >>> context = zcml.load_string(''' ... ... ... ... ''' % weatherTemplate) >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='weather2') >>> viewlet().strip() u'
    sunny
    ' Okay, so the template-driven cases work. But just specifying a class should also work: >>> context = zcml.load_string(''' ... ... ... ... ''') >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, name='sport') >>> viewlet() u'Red Sox vs. White Sox' It should also be possible to specify an alternative attribute of the class to be rendered upon calling the viewlet: >>> context = zcml.load_string(''' ... ... ... ... ''') >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='stock') >>> viewlet.render() u'SRC $5.19' A final feature the ``viewlet`` directive supports is the additional specification of any amount keyword arguments: >>> context = zcml.load_string(''' ... ... ... ... ''') >>> viewlet = zope.component.getMultiAdapter( ... (content, request, view, manager), interfaces.IViewlet, ... name='stock2') >>> viewlet.weight u'8' Error Scenarios --------------- Neither the class or template have been specified: >>> context = zcml.load_string(''' ... ... ... ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 3.2-7.8 ConfigurationError: Must specify a class or template The specified attribute is not ``__call__``, but also a template has been specified: >>> context = zcml.load_string(''' ... ... ... ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 3.2-9.8 ConfigurationError: Attribute and template cannot be used together. Now, we are not specifying a template, but a class that does not have the specified attribute: >>> context = zcml.load_string(''' ... ... ... ... ''') Traceback (most recent call last): ... ZopeXMLConfigurationError: File "", line 3.2-9.8 ConfigurationError: The provided class doesn't have the specified attribute ================================ Viewlet Directive Security ================================ Before we can begin, we need to set up a few things. We need a manager account: >>> uf = self.folder.acl_users >>> _ignored = uf._doAddUser('manager', 'r00t', ['Manager'], []) Finally, we need to setup a traversable folder. Otherwise, Five won't get do its view lookup magic: >>> from OFS.Folder import manage_addFolder >>> manage_addFolder(self.folder, 'ftf') Now we can register another simple viewlet manager: >>> from Products.Five.viewlet.tests import INewColumn >>> context = zcml.load_string(''' ... ... ... ... ''') And a view to call our new content provider: >>> testTemplate = os.path.join(temp_dir, 'test.pt') >>> open(testTemplate, 'w').write(''' ... ... ...

    Weather

    ...
    ... ... ... ''') >>> context = zcml.load_string(''' ... ... ... ... ''' % testTemplate) We now register some viewlets with different permissions: >>> weatherTemplate = os.path.join(temp_dir, 'weather2.pt') >>> open(weatherTemplate, 'w').write(''' ...
    sunny
    ... ''') >>> context = zcml.load_string(''' ... ... ... ... ''' % weatherTemplate) >>> context = zcml.load_string(''' ... ... ... ... ''' % weatherTemplate) If we make the request as a manager, we should see both viewlets: >>> print http(r""" ... GET /test_folder_1_/ftf/@@securitytest_view HTTP/1.1 ... Authorization: Basic manager:r00t ... """, handle_errors=False) HTTP/1.1 200 OK ...

    ... But when we make an anonymous request, we will only see the public viewlet: >>> print http(r""" ... GET /test_folder_1_/ftf/@@securitytest_view HTTP/1.1 ... """, handle_errors=False) HTTP/1.1 200 OK ...

    ... A Dynamic Viewlet ----------------- A viewlet template can of course contain some dynamic code, let's see how that works: >>> dynWeatherTemplate = os.path.join(temp_dir, 'dynamic_weather.pt') >>> open(dynWeatherTemplate, 'w').write(u''' ...
    ''' ... ) >>> context = zcml.load_string(''' ... ... ... ... ''' % dynWeatherTemplate) Now we request the view to ensure that we can see the dynamic template rendered as expected: >>> print http(r""" ... GET /test_folder_1_/ftf/@@securitytest_view HTTP/1.1 ... """, handle_errors=False) HTTP/1.1 200 OK ...

Using content providers allows us to insert one piece of HTML content. In most Web development, however, you are often interested in defining some sort of region and then allow developers to register content for those regions. >>> from zope.viewlet import interfaces Setup traversal stuff >>> import Products.Five >>> from Zope2.App import zcml >>> zcml.load_config("configure.zcml", Products.Five) Set a loose security policy because these are unit tests, security will be tested in another file: >>> from AccessControl import SecurityManager >>> from Products.Five.viewlet.tests import UnitTestSecurityPolicy >>> from AccessControl.SecurityManagement import newSecurityManager >>> from AccessControl.SecurityManagement import noSecurityManager >>> noSecurityManager() >>> oldPolicy = SecurityManager.setSecurityPolicy(UnitTestSecurityPolicy()) Design Notes ------------ As mentioned above, besides inserting snippets of HTML at places, we more frequently want to define a region in our page and allow specialized content providers to be inserted based on configuration. Those specialized content providers are known viewlets and are only available inside viewlet managers, which are just a more complex example of content providers. Unfortunately, the Java world does not implement this layer separately. The viewlet manager is most similar to a Java "channel", but we decided against using this name, since it is very generic and not very meaningful. The viewlet has no Java counterpart, since Java does not implement content providers using a component architecture and thus does not register content providers specifically for viewlet managers, which I believe makes the Java implementation less useful as a generic concept. In fact, the main design goal in the Java world is the implementation of reusable and sharable portlets. The scope for Zope is larger, since we want to provide a generic framework for building pluggable user interfaces. The Viewlet Manager ------------------- In this implementation of viewlets, those regions are just content providers called viewlet managers that manage a special type of content providers known as viewlets. Every viewlet manager handles the viewlets registered for it: >>> from Products.Five.viewlet.tests import ILeftColumn You can then create a viewlet manager using this interface now: >>> from Products.Five.viewlet import manager >>> LeftColumn = manager.ViewletManager('left', ILeftColumn) Now we have to instantiate it in the context of an actual zope object: >>> import zope.interface >>> from OFS import SimpleItem, Folder >>> class Content(SimpleItem.SimpleItem): ... zope.interface.implements(zope.interface.Interface) >>> obj_id = self.folder._setObject('content1', Content()) >>> content = self.folder[obj_id] >>> from zope.publisher.browser import TestRequest >>> request = TestRequest() >>> from Products.Five.browser import BrowserView as View >>> view = View(content, request) >>> leftColumn = LeftColumn(content, request, view) So initially nothing gets rendered: >>> leftColumn.update() >>> leftColumn.render() u'' But now we register some viewlets for the manager >>> import zope.component >>> from zope.publisher.interfaces.browser import IDefaultBrowserLayer >>> from zope.browser.interfaces import IBrowserView >>> class WeatherBox(object): ... zope.interface.implements(interfaces.IViewlet) ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... self.context = context ... ... def update(self): ... pass ... ... def render(self): ... return u'
    It is sunny today!
    ' >>> zope.component.provideAdapter( ... WeatherBox, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, ILeftColumn), ... interfaces.IViewlet, name='weather') >>> class SportBox(object): ... zope.interface.implements(interfaces.IViewlet) ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... self.context = context ... ... def update(self): ... pass ... ... def render(self): ... return u'
    Patriots (23) : Steelers (7)
    ' >>> zope.component.provideAdapter( ... SportBox, ... (zope.interface.Interface, IDefaultBrowserLayer, ... IBrowserView, ILeftColumn), ... interfaces.IViewlet, name='sport') and thus the left column is filled: >>> leftColumn.update() >>> print leftColumn.render()
    Patriots (23) : Steelers (7)
    It is sunny today!
    But this is of course pretty lame, since there is no way of specifying how the viewlets are put together. But we have a solution. The second argument of the ``ViewletManager()`` function is a template in which we can specify how the viewlets are put together: >>> import os, tempfile >>> temp_dir = tempfile.mkdtemp() >>> leftColTemplate = os.path.join(temp_dir, 'leftCol.pt') >>> open(leftColTemplate, 'w').write(''' ...
    ... ...
    ... ''') >>> LeftColumn = manager.ViewletManager('left', ILeftColumn, ... template=leftColTemplate) >>> leftColumn = LeftColumn(content, request, view) TODO: Fix this silly thing; viewlets should be directly available. As you can see, the viewlet manager provides a global ``options/viewlets`` variable that is an iterable of all the avialable viewlets in the correct order: >>> leftColumn.update() >>> print leftColumn.render().strip()
    Patriots (23) : Steelers (7)
    It is sunny today!
    You can also lookup the viewlets directly for management purposes: >>> leftColumn['weather'] >>> leftColumn.get('weather') If the viewlet is not found, then the expected behavior is provided: >>> leftColumn['stock'] Traceback (most recent call last): ... ComponentLookupError: No provider with name `stock` found. >>> leftColumn.get('stock') is None True Customizing the default Viewlet Manager --------------------------------------- One important feature of any viewlet manager is to be able to filter and sort the viewlets it is displaying. The default viewlet manager that we have been using in the tests above, supports filtering by access availability and sorting via the viewlet's ``__cmp__()`` method (default). You can easily override this default policy by providing a base viewlet manager class. In our case we will manage the viewlets using a global list: >>> shown = ['weather', 'sport'] The viewlet manager base class now uses this list: >>> class ListViewletManager(object): ... ... def filter(self, viewlets): ... viewlets = super(ListViewletManager, self).filter(viewlets) ... return [(name, viewlet) ... for name, viewlet in viewlets ... if name in shown] ... ... def sort(self, viewlets): ... viewlets = dict(viewlets) ... return [(name, viewlets[name]) for name in shown] Let's now create a new viewlet manager: >>> LeftColumn = manager.ViewletManager( ... 'left', ILeftColumn, bases=(ListViewletManager,), ... template=leftColTemplate) >>> leftColumn = LeftColumn(content, request, view) So we get the weather box first and the sport box second: >>> leftColumn.update() >>> print leftColumn.render().strip()
    It is sunny today!
    Patriots (23) : Steelers (7)
    Now let's change the order... >>> shown.reverse() and the order should switch as well: >>> leftColumn.update() >>> print leftColumn.render().strip()
    Patriots (23) : Steelers (7)
    It is sunny today!
    Of course, we also can remove a shown viewlet: >>> weather = shown.pop() >>> leftColumn.update() >>> print leftColumn.render().strip()
    Patriots (23) : Steelers (7)
    Viewlet Base Classes -------------------- To make the creation of viewlets simpler, a set of useful base classes and helper functions are provided: >>> from Products.Five.viewlet import viewlet The first class is a base class that simply defines the constructor: >>> base = viewlet.ViewletBase('context', 'request', 'view', 'manager') >>> base.context 'context' >>> base.request 'request' >>> base.__parent__ 'view' >>> base.manager 'manager' But a default ``render()`` method implementation is not provided: >>> base.render() Traceback (most recent call last): ... NotImplementedError: `render` method must be implemented by subclass. If you have already an existing class that produces the HTML content in some method, then the ``SimpleAttributeViewlet`` might be for you, since it can be used to convert any class quickly into a viewlet: >>> class FooViewlet(viewlet.SimpleAttributeViewlet): ... __page_attribute__ = 'foo' ... ... def foo(self): ... return 'output' The `__page_attribute__` attribute provides the name of the function to call for rendering. >>> foo = FooViewlet('context', 'request', 'view', 'manager') >>> foo.foo() 'output' >>> foo.render() 'output' If you specify `render` as the attribute an error is raised to prevent infinite recursion: >>> foo.__page_attribute__ = 'render' >>> foo.render() Traceback (most recent call last): ... AttributeError: render The same is true if the specified attribute does not exist: >>> foo.__page_attribute__ = 'bar' >>> foo.render() Traceback (most recent call last): ... AttributeError: 'FooViewlet' object has no attribute 'bar' To create simple template-based viewlets you can use the ``SimpleViewletClass()`` function. This function is very similar to its view equivalent and is used by the ZCML directives to create viewlets. The result of this function call will be a fully functional viewlet class. Let's start by simply specifying a template only: >>> template = os.path.join(temp_dir, 'demoTemplate.pt') >>> open(template, 'w').write('''
    contents
    ''') >>> Demo = viewlet.SimpleViewletClass(template) >>> print Demo(content, request, view, manager).render()
    contents
    Now let's additionally specify a class that can provide additional features: >>> class MyViewlet(object): ... myAttribute = 8 >>> Demo = viewlet.SimpleViewletClass(template, bases=(MyViewlet,)) >>> MyViewlet in Demo.__bases__ True >>> Demo(content, request, view, manager).myAttribute 8 The final important feature is the ability to pass in further attributes to the class: >>> Demo = viewlet.SimpleViewletClass( ... template, attributes={'here': 'now', 'lucky': 3}) >>> demo = Demo(content, request, view, manager) >>> demo.here 'now' >>> demo.lucky 3 As for all views, they must provide a name that can also be passed to the function: >>> Demo = viewlet.SimpleViewletClass(template, name='demoViewlet') >>> demo = Demo(content, request, view, manager) >>> demo.__name__ 'demoViewlet' In addition to the the generic viewlet code above, the package comes with two viewlet base classes and helper functions for inserting CSS and Javascript links into HTML headers, since those two are so very common. I am only going to demonstrate the helper functions here, since those demonstrations will fully demonstrate the functionality of the base classes as well. >>> from zope.interface import Interface >>> from zope.component import getGlobalSiteManager >>> from zope.publisher.interfaces.browser import IDefaultBrowserLayer >>> def registerResource(name, factory): ... gsm = getGlobalSiteManager() ... gsm.registerAdapter( ... factory, ... required=(IDefaultBrowserLayer, ), ... provided=Interface, ... name=name, ... ) The viewlet will look up the resource it was given and tries to produce the absolute URL for it: >>> class JSResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/resource.js' >>> registerResource('resource.js', JSResource) >>> JSViewlet = viewlet.JavaScriptViewlet('resource.js') >>> print JSViewlet(content, request, view, manager).render().strip() The same works for the CSS resource viewlet: >>> class CSSResource(object): ... def __init__(self, request): ... self.request = request ... ... def __call__(self): ... return '/@@/resource.css' >>> registerResource('resource.css', CSSResource) >>> CSSViewlet = viewlet.CSSViewlet('resource.css') >>> print CSSViewlet(content, request, view, manager).render().strip() You can also change the media type and the rel attribute: >>> CSSViewlet = viewlet.CSSViewlet('resource.css', media='print', rel='css') >>> print CSSViewlet(content, request, view, manager).render().strip() A Complex Example ----------------- The Data ~~~~~~~~ So far we have only demonstrated simple (maybe overly trivial) use cases of the viewlet system. In the following example, we are going to develop a generic contents view for files. The step is to create a file component: >>> class IFile(zope.interface.Interface): ... data = zope.interface.Attribute('Data of file.') >>> class File(SimpleItem.SimpleItem): ... zope.interface.implements(IFile) ... def __init__(self, data=''): ... self.__name__ = '' ... self.data = data Since we want to also provide the size of a file, here a simple implementation of the ``ISized`` interface: >>> from zope import size >>> class FileSized(object): ... zope.interface.implements(size.interfaces.ISized) ... zope.component.adapts(IFile) ... ... def __init__(self, file): ... self.file = file ... ... def sizeForSorting(self): ... return 'byte', len(self.file.data) ... ... def sizeForDisplay(self): ... return '%i bytes' %len(self.file.data) >>> zope.component.provideAdapter(FileSized) We also need a container to which we can add files: >>> class Container(Folder.Folder): ... def __setitem__(self, name, value): ... self._setObject(name, value) ... value.__name__ = name Here is some sample data: >>> container = Container() >>> obj_id = self.folder._setObject('container', container) >>> container = self.folder[obj_id] >>> container['mypage.html'] = File('Hello World!') >>> container['data.xml'] = File('Hello World!') >>> container['test.txt'] = File('Hello World!') The View ~~~~~~~~ The contents view of the container should iterate through the container and represent the files in a table: >>> contentsTemplate = os.path.join(temp_dir, 'contents.pt') >>> open(contentsTemplate, 'w').write(''' ... ... ...

    Cotnents

    ...
    ... ... ... ''') >>> from Products.Five.browser.metaconfigure import makeClassForTemplate >>> Contents = makeClassForTemplate(contentsTemplate, name='contents.html') The Viewlet Manager ~~~~~~~~~~~~~~~~~~~ Now we have to write our own viewlet manager. In this case we cannot use the default implementation, since the viewlets will be looked up for each different item: >>> shownColumns = [] >>> class ContentsViewletManager(object): ... zope.interface.implements(interfaces.IViewletManager) ... index = None ... ... def __init__(self, context, request, view): ... self.context = context ... self.request = request ... self.__parent__ = view ... ... def update(self): ... rows = [] ... for name, value in self.context.objectItems(): ... rows.append( ... [zope.component.getMultiAdapter( ... (value, self.request, self.__parent__, self), ... interfaces.IViewlet, name=colname) ... for colname in shownColumns]) ... [entry.update() for entry in rows[-1]] ... self.rows = rows ... ... def render(self, *args, **kw): ... return self.index(*args, **kw) Now we need a template to produce the contents table: >>> tableTemplate = os.path.join(temp_dir, 'table.pt') >>> open(tableTemplate, 'w').write(''' ... ... ... ... ...
    ... ...
    ... ''') From the two pieces above, we can generate the final viewlet manager class and register it (it's a bit tedious, I know): >>> from Products.Five.browser.pagetemplatefile import ZopeTwoPageTemplateFile >>> ContentsViewletManager = type( ... 'ContentsViewletManager', (ContentsViewletManager,), ... {'index': ZopeTwoPageTemplateFile('table.pt', temp_dir)}) >>> zope.component.provideAdapter( ... ContentsViewletManager, ... (Container, IDefaultBrowserLayer, zope.interface.Interface), ... interfaces.IViewletManager, name='contents') Since we have not defined any viewlets yet, the table is totally empty: >>> contents = Contents(container, request) >>> print contents().strip()

    Cotnents

    The Viewlets and the Final Result ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Now let's create a first viewlet for the manager... >>> class NameViewlet(object): ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... self.context = context ... ... def update(self): ... pass ... ... def render(self): ... return self.context.__name__ and register it: >>> zope.component.provideAdapter( ... NameViewlet, ... (IFile, IDefaultBrowserLayer, ... zope.interface.Interface, interfaces.IViewletManager), ... interfaces.IViewlet, name='name') Note how you register the viewlet on ``IFile`` and not on the container. Now we should be able to see the name for each file in the container: >>> print contents().strip()

    Cotnents

    Waaa, nothing there! What happened? Well, we have to tell our user preferences that we want to see the name as a column in the table: >>> shownColumns = ['name'] >>> print contents().strip()

    Cotnents

    mypage.html
    data.xml
    test.txt
    Let's now write a second viewlet that will display the size of the object for us: >>> class SizeViewlet(object): ... ... def __init__(self, context, request, view, manager): ... self.__parent__ = view ... self.context = context ... ... def update(self): ... pass ... ... def render(self): ... return size.interfaces.ISized(self.context).sizeForDisplay() >>> zope.component.provideAdapter( ... SizeViewlet, ... (IFile, IDefaultBrowserLayer, ... zope.interface.Interface, interfaces.IViewletManager), ... interfaces.IViewlet, name='size') After we added it to the list of shown columns, >>> shownColumns = ['name', 'size'] we can see an entry for it: >>> print contents().strip()

    If we switch the two columns around, >>> shownColumns = ['size', 'name'] the result will be >>> print contents().strip()

    Supporting Sorting ~~~~~~~~~~~~~~~~~~ Oftentimes you also want to batch and sort the entries in a table. Since those two features are not part of the view logic, they should be treated with independent components. In this example, we are going to only implement sorting using a simple utility: >>> class ISorter(zope.interface.Interface): ... ... def sort(values): ... """Sort the values.""" >>> class SortByName(object): ... zope.interface.implements(ISorter) ... ... def sort(self, values): ... return sorted(values, lambda x, y: cmp(x.__name__, y.__name__)) >>> zope.component.provideUtility(SortByName(), name='name') >>> class SortBySize(object): ... zope.interface.implements(ISorter) ... ... def sort(self, values): ... return sorted( ... values, ... lambda x, y: cmp(size.interfaces.ISized(x).sizeForSorting(), ... size.interfaces.ISized(y).sizeForSorting())) >>> zope.component.provideUtility(SortBySize(), name='size') Note that we decided to give the sorter utilities the same name as the corresponding viewlet. This convention will make our implementation of the viewlet manager much simpler: >>> sortByColumn = '' >>> class SortedContentsViewletManager(manager.ViewletManagerBase): ... zope.interface.implements(interfaces.IViewletManager) ... index = None ... ... def __init__(self, context, request, view): ... self.context = context ... self.request = request ... self.__parent__ = view ... ... def update(self): ... values = self.context.objectValues() ... ... if sortByColumn: ... sorter = zope.component.queryUtility(ISorter, sortByColumn) ... if sorter: ... values = sorter.sort(values) ... ... rows = [] ... for value in values: ... rows.append( ... [zope.component.getMultiAdapter( ... (value, self.request, self.__parent__, self), ... interfaces.IViewlet, name=colname) ... for colname in shownColumns]) ... [entry.update() for entry in rows[-1]] ... self.rows = rows ... ... def render(self, *args, **kw): ... return self.index(*args, **kw) As you can see, the concern of sorting is cleanly separated from generating the view code. In MVC terms that means that the controller (sort) is logically separated from the view (viewlets). Let's now do the registration dance for the new viewlet manager. We simply override the existing registration: >>> SortedContentsViewletManager = type( ... 'SortedContentsViewletManager', (SortedContentsViewletManager,), ... {'index': ZopeTwoPageTemplateFile('table.pt', temp_dir)}) >>> zope.component.provideAdapter( ... SortedContentsViewletManager, ... (Container, IDefaultBrowserLayer, zope.interface.Interface), ... interfaces.IViewletManager, name='contents') Finally we sort the contents by name: >>> shownColumns = ['name', 'size'] >>> sortByColumn = 'name' >>> print contents().strip()

    Cotnents

    data.xml 31 bytes
    mypage.html 38 bytes
    test.txt 12 bytes
    Now let's sort by size: >>> sortByColumn = 'size' >>> print contents().strip()

    That's it! As you can see, in a few steps we have built a pretty flexible contents view with selectable columns and sorting. However, there is a lot of room for extending this example: - Table Header: The table header cell for each column should be a different type of viewlet, but registered under the same name. The column header viewlet also adapts the container not the item. The header column should also be able to control the sorting. - Batching: A simple implementation of batching should work very similar to the sorting feature. Of course, efficient implementations should somehow combine batching and sorting more effectively. - Sorting in ascending and descending order: Currently, you can only sort from the smallest to the highest value; however, this limitation is almost superficial and can easily be removed by making the sorters a bit more flexible. - Further Columns: For a real application, you would want to implement other columns, of course. You would also probably want some sort of fallback for the case that a viewlet is not found for a particular container item and column.

    Testing legacy content providers and viewlets ============================================= >>> browser.open('http://localhost/test_folder_1_/aqlegacyprovider') >>> print browser.contents

    Content provider inheriting from Explicit

    >>> browser.open('http://localhost/test_folder_1_/aqlegacymanager') >>> print browser.contents

    BrowserView viewlet Viewlet inheriting from Explicit

    Testing namespace traversal =========================== Namespace traversal can turn up objects during traversal without attribute access. That means they might not be wrapped by default. Here we make sure that they are wrapped and that things like the request can be acquired. First let's try ``restrictedTraverse()``: >>> foo = self.folder.restrictedTraverse('++aqlegacy++foo') >>> import Acquisition >>> Acquisition.aq_acquire(foo, 'REQUEST') Now let's try URL traversal: >>> browser.open('http://localhost/test_folder_1_/++aqlegacy++foo/index.html') >>> print browser.contents

    The falcon has taken flight

    Testing keyword arguments ========================= ViewPageTemplateFile's take arbitrary keyword arguments: >>> view = getMultiAdapter((self.folder, request), name='template') >>> template = view.template >>> print template(foo=1, bar=2)

    The falcon has taken flight

    Passing in an argument called instance was supported by the old Five version of ViewPageTemplateFile, so we still need to support it. >>> print template(instance='allowed')

    The falcon has taken flight

    No arguments required ===================== ViewPageTemplateFile's require no arguments, but you can only use them as class variables: >>> view = getMultiAdapter((self.folder, request), name='template_two') >>> print view() Traceback (most recent call last): ...

To this end we have copied the tests from zope.contentprovider and made them work with Five. We have defined a muber of relevant views which use the new tal expression in providers.zcml: >>> from zope.contentprovider import interfaces >>> import Products.Five.browser.tests >>> from Zope2.App import zcml >>> zcml.load_config("configure.zcml", Products.Five) >>> zcml.load_config('provider.zcml', package=Products.Five.browser.tests) Content Providers ----------------- Content Provider is a term from the Java world that refers to components that can provide HTML content. It means nothing more! How the content is found and returned is totally up to the implementation. The Zope touch to the concept is that content providers are multi-adapters that are looked up by the context, request (and thus the layer/skin), and view they are displayed in. So let's create a simple content provider: >>> import zope.interface >>> import zope.component >>> from zope.publisher.interfaces import browser >>> class MessageBox(object): ... zope.interface.implements(interfaces.IContentProvider) ... zope.component.adapts(zope.interface.Interface, ... browser.IDefaultBrowserLayer, ... zope.interface.Interface) ... message = u'My Message' ... ... def __init__(self, context, request, view): ... self.__parent__ = view ... ... def update(self): ... pass ... ... def render(self): ... return u'
    %s
    ' %self.message The ``update()`` method is executed during phase one. Since no state needs to be calculated and no data is modified by this simple content provider, it is an empty implementation. The ``render()`` method implements phase 2 of the process. We can now instantiate the content provider (manually) and render it: >>> box = MessageBox(None, None, None) >>> box.render() u'
    My Message
    ' Since our content provider did not require the context, request or view to create its HTML content, we were able to pass trivial dummy values into the constructor. Also note that the provider must have a parent (using the ``__parent__`` attribute) specified at all times. The parent must be the view the provider appears in. The TALES ``provider`` Expression --------------------------------- The ``provider`` expression will look up the name of the content provider, call it and return the HTML content. The first step, however, will be to register our content provider with the component architecture: >>> zope.component.provideAdapter(MessageBox, name='mypage.MessageBox') The content provider must be registered by name, since the TALES expression uses the name to look up the provider at run time. >>> from Products.Five.tests.testing.simplecontent import manage_addSimpleContent >>> manage_addSimpleContent(self.folder, 'content_obj', 'ContentObj') >>> content = self.folder.content_obj Finally we publish the view: >>> print http(r''' ... GET /test_folder_1_/content_obj/main.html HTTP/1.1 ... ''') HTTP/1.1 200 OK ...

''', handle_errors=False) Traceback (most recent call last): ... ContentProviderLookupError: ...mypage.UnknownName... Additional Data from TAL ~~~~~~~~~~~~~~~~~~~~~~~~ The ``provider`` expression allows also for transferring data from the TAL context into the content provider. This is accomplished by having the content provider implement an interface that specifies the attributes and provides ``ITALNamespaceData``: >>> import zope.schema >>> class IMessageText(zope.interface.Interface): ... message = zope.schema.Text(title=u'Text of the message box') >>> zope.interface.directlyProvides(IMessageText, ... interfaces.ITALNamespaceData) Now the message box can receive its text from the TAL environment: >>> class DynamicMessageBox(MessageBox): ... zope.interface.implements(IMessageText) >>> zope.component.provideAdapter( ...

The ZPublisher marshalls arguments to called methods from the request based on the method's signature. This however assumes that it finds the real callable method. However in case of the autogenerated __call__ method of a view, the real method is wrapped. Although the publisher correctly handles this by looking at the __browser_default__ and applying the request on the real method, Plone's portal factory does not do this correctly, thus causing these method calls fail with TypeError, since no parameters will be marshalled to the browser default methods if within the portal factory. The applied fix changes the __call__ in such a way that it is not wrapper any more, but yields the original callable instead. This test simply checks that this is so, in other words this is a check that would have failed with the original version.

This crazy requirement luckily isn't true for zope.publisher, so it should be possible to write docstring-less view classes that are still published through ZPublisher. We see that even though the callables have no docstring, they are published nevertheless: >>> print http(r""" ... GET /test_folder_1_/testoid/nodoc-function HTTP/1.1 ... """) HTTP/1.1 200 OK ...

GET /test_folder_1_/testoid/nodoc-object HTTP/1.1 ... """) HTTP/1.1 200 OK ... No docstring Security -------- Browser pages need to be protected with a permission. Let's test those; we start by adding two users: >>> uf = self.folder.acl_users >>> _ignored = uf._doAddUser('viewer', 'secret', [], []) >>> _ignored = uf._doAddUser('manager', 'r00t', ['Manager'], []) >>> protected_view_names = [ ...

The contents of a Temporary Folder are lost upon shutdown. Creating By default, Zope will create a Temporary Folder named "temp_folder" in the root of every Zope installation. This Temporary Folder will be used by the Zope Sessions machinery, but it may be used for other purposes as well. You may create additional Temporary Folders. Creating a Temporary Folder is fairly straightfoward; they are created in the same way as a "regular" Folder through the Zope management interface: - Specify an id (a name) for the folder - Specify an optional title for the folder Usage Once created, a Temporary Folder acts just like regular Folder object with the exception that the items which it contains will be lost upon Zope shutdown and restart. Since Temporary Folders use RAM to store data, it is advised to add items to a Temporary Folder sparingly. The capacity of a Temporary Folder is limited by available RAM. Interaction with ZEO Temporary Folders exist local to the Zope server. Thus, each server in a ZEO cluster would have their own private copy of data in a Temporary Folder. Only temporary data that should be local to a specific Zope instance should go into a Temporary Folder. Items which need to be shared between Zope servers in a ZEO cluster should not be placed in Temporary Folders. zope2.13-2.13.21/source/Zope2/src/Products/TemporaryFolder/TemporaryFolder.py0000644000175000017500000000641112214017422025633 0ustar arnauarnau############################################################################## # # Copyright (c) 2002 Zope Foundation and Contributors. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

Browser id managers are part of the Zope sessioning machinery. Form options available are: Id -- you cannot choose an 'id' for your browser id manager. It must always be "browser_id_manager". Additionally, you cannot rename a browser id manager. This is required in the current implementation so that session data managers can find browser id managers via Zope acquisition. This may be changed in a later release. Title -- the browser id manager title. Browser Id Name -- the cookie name and/or form variable name used for this browser id manager instance. This will be the name looked up in the 'cookies' or 'form' REQUEST namespaces when the browser id manager attempts to find a cookie or form variable with a browser id in it. Look for Browser Id In -- choose any of 'Forms and Query Strings', 'URLs', or 'Cookies'. The browser id name/value will be looked for within these places. Automatically Encode Zope-Generated URLs With A Browser Id -- if this is selected, URLs generated by Zope (such as URLs which come as a result of calling an object's 'absolute_url' method) will be encoded with a browser name and browser id as the first two elements of the URL path. Cookie path -- this is the 'path' element which should be sent in the session token cookie. For more information, see the Netscape Cookie specification at http://home.netscape.com/newsref/std/cookie_spec.html. Cookie domain -- this is the "domain" element which should be sent in the browser id cookie. For more information, see the Netscape Cookie specification at http://home.netscape.com/newsref/std/cookie_spec.html. Leaving this form element blank results in no domain element in the cookie. If you change the cookie domain here, the value you enter must have at least two dots (as per the cookie spec). Cookie lifetime in days -- browser id cookies sent to browsers will last this many days on a remote system before expiring if this value is set. If this value is 0, cookies will persist on client browsers for only as long as the browser is open. Only send cookie over https -- if this flag is set, only send cookies to remote browsers if they're communicating with us over https. The browser id cookie sent under this circumstance will also have the 'secure' flag set in it, which the remote browser should interpret as a request to refrain from sending the cookie back to the server over an insecure (non-https) connection. NOTE: In the case you wish to share browser id cookies between https and non-https connections from the same browser, do not set this flag. After reviewing and changing these options, click the "Add" button to instantiate a browser id manager. You can manage a browser id manager by visiting it in the management interface. Instantiating Multiple Browser Id Managers (Optional) If you've got special needs, you may want to instantiate more than one browser id manager. In its default configuration, Zope will not allow you to create a browser id manager if one is installed in the root or in a place where the new browser id manager can acquire the original browser id manager via its containment path (for programmers: the session id manager's class' Zope __replaceable__ property is set to UNIQUE). This means, practically, that if you wish to have multiple browser id managers, you need to carefully delete the root browser id manager, then you need to place additional browser id managers in the most deeply-nested containers first, working your way out towards the root, finally replacing the root browser id manager if desired.

It is part of the Zope sessioning machinery. Programmers will sometimes interact with a session data manager in order to obtain information about session data. You can place a session data manager in any Zope container,as long as a browser id manager object can be acquired from that container. The session data manager will use the first acquired object named "browser_id_manager" as a browser id manager. Choose "Session Data Manager" within the container you wish to house the session data manager from the "Add" dropdown box in the Zope management interface. The session data manager add form displays these options: id -- choose an id for the session data manager title -- choose a title for the session data manager transient object container path -- the path in Zope to a transient object container which will store the actual session data. This path is /temp_folder/transient_container in a default Zope installation. place SESSION in REQUEST as -- If set, the REQUEST variable will be populated with the session object, stored as the given name (default is 'SESSION') After reviewing and changing these options, click the "Add" button to instantiate a session data manager. You can manage a session data manager by visiting it in the management interface. You may change all options available during the add process by doing this.

    A Session Data Manager object is responsible for maintaining a relationship between session data objects and Zope browser ids. It is part of the Zope sessioning machinery. Programmers may interact with a session data manager in order to obtain information about session data, but will more often use the REQUEST.SESSION object to do sessioning-related tasks.

    Zope Browser Id Manager objects allow Zope to differentiate between site visitors by "tagging" each of their browsers with a unique identifier. This is useful if you need to tell visitors apart from one another even if they do not "log in" to your site. Browser Id Managers are generally used by interacting with the Zope sessioning machinery.

    Zope Session Data Managers objects keep track of your users' session data objects. Developers interact with a Session Data Manager in order to store and retrieve information during a user session. A Session Data Manager communicates with a Browser Id Manager to determine the session information for the current user, and hands out Session Data Objects related to that user.

    The Virtual Host Monster supports virtual hosting

    It changes the protocol, host, and/or path of URLs generated by Zope. Values affected include REQUEST variables starting with URL or BASE (such as URL1, BASE2, URLPATH0), and the absolute_url() methods of objects. By changing these, the Virtual Host Monster allows you to host several different domains in a single Zope.

    The most common sort of virtual hosting setup is one in which you create a Folder in your Zope root for each domain that you want to serve. For instance http://www.buystuff.com is served from Folder /buystuff.com while http://www.mycause.org is served from /mycause.org.

    One is enough

    A single Virtual Host Monster in your Zope root can handle all of your virtual hosting needs. It doesn't matter what Id you give it, as long as nothing else in your site has the same Id.

    You must add special names in the path

    The VHM doesn't do anything unless it sees one of the following special path elements in a URL: VirtualHostBase sets the protocol and host, while VirtualHostRoot sets the path root.

    If the URL path of a request begins with "/VirtualHostBase/http/www.buystuff.com", for instance, then URLs generated by Zope will start with http://www.buystuff.com. Since the port number was not specified, it is left unchanged. If your Zope is running on port 8080, and you want generated URLs not to include this port number, you must use "/VirtualHostBase/http/www.buystuff.com:80".

    If the URL contains VirtualHostRoot, then all path elements up to that point are removed from generated URLs. For instance, a request with path "/a/b/c/VirtualHostRoot/d" will traverse "a/b/c/d" and then generate a URL with path /d.

    You add these names by rewriting incoming URLs

    Visitors to your site don't see these special names, of course. You insert them into the path using either an external rewriter, such as an Apache RewriteRule or ProxyPass directive, or by setting up a mapping on the "Mappings" tab.

    For example, suppose Zope is running on port 8080 behind an Apache running on port 80. You place a Virtual Host Monster in the Zope root Folder, and use Apache to rewrite "/(.*)" to http://localhost:8080/VirtualHostBase/http/www.buystuff.com:80/buystuff.com/VirtualHostRoot/$1.

    You could get the same effect in a standalone Zope by adding the line www.buystuff.com/buystuff.com to the "Mappings" tab. In either case, requests for http://www.buystuff.com/anything will look for Zope object /buystuff.com/anything.

    You should only use the "Mappings" tab for simple virtual hosting, in a Zope that is serving requests directly. Each mapping line is a host name followed by a path to a Folder. The VHM checks the host specified in each incoming request to see if it is in the list. If it is, then the corresponding path is inserted at the start of the path, followed by "VirtualHostRoot".

    You can match multiple subdomains by putting "*." in front of the host name, as in "*.buystuff.com". If an exact match exists, it is used instead of a wildcard match.

    Inside-out hosting

    Another use for virtual hosting is to make Zope appear to be part of a site controlled by another server. For example, Zope might only serve the contents of http://www.mycause.org/dynamic_stuff. To accomplish this, you want to add "dynamic_stuff" to the start of all Zope-generated URLs.

    If you insert VirtualHostRoot, followed by one or more path elements that start with '_vh_', then these elements will be ignored during traversal and then added (without the '_vh_') to the start of generated URLs. For instance, a request for "/a/VirtualHostRoot/_vh_z/" will traverse "a" and then generate URLs that start with /z.

    In our example, you would have the main server send requests for http://www.mycause.org/dynamic_stuff/anything to Zope, rewritten as /VirtualHostRoot/_vh_dynamic_stuff/anything.

    You may edit the mappings for this Virtual Host Monster using the form below. You don't need to use this tab if you are using Apache or some other front-end server to rewrite requests. This is only for simple virtual hosting in a bare Zope server. If you place the hostname that you use to manage your Zope in this list you are likely to regret it, and will probably need to manage Zope using its raw IP address to fix things.

    Basics

    SiteAccess started as a Product to enable Zope Virtual Hosting, then became more generalized. Virtual Hosting is the ability to publish sub-objects of a Zope hierarchy as though they were the root of their own site. For example, it allows 'http:/www.silly-walks.org/current' to publish the Zope object 'silly-walks/current' instead of just 'current'.

    Usage

    See:

    What does SiteAccess do?

    SiteAccess provides the ability to force ZPublisher to call objects of your choice as it enters any folder. With this capability, you can designate a method in the Zope root to examine the request parameters and alter or replace the URL.

    If an Access Rule is broken, and is preventing normal access, it can be disabled by restarting Zope with environment variable SUPPRESS_ACCESSRULE set.

    zope2.13-2.13.21/source/Zope2/src/Products/SiteAccess/doc/vhosting.html0000644000175000017500000001663312214017422024356 0ustar arnauarnau Virtual Site Hosting

    Getting Started

    Before you can set up virtual hosting in Zope, you need to answer two questions:
    • What is the URI of each site's logical root?
    • What is the corresponding path to the physical root?
    Suppose, for example, that you want to use Zope to host the domain www.hotsite.com, and you want 'http://www.hotsite.com' to publish the Zope object '/hotsite/index_html'. Then 'http://www.hotsite.com' is the URI of your logical root, and '/hotsite' is the path to your physical root.

    Example 1: One Site

    Put a SiteRoot in '/hotsite', your site's physical root, and accept the default Path. Create a DTML Method in the Zope root folder containing 
    Is the first-level domain 'hotsite.com'? Ignore sub-domains and port number.
<dtml-if "_.string.split(_.string.split(HTTP_HOST, ':')[0], '.')[-2:]==['hotsite', 'com']">
  Add physical root: 
  <dtml-call "REQUEST['TraversalRequestNameStack'].append('hotsite')">
</dtml-if >
    Use "Set Access Rule" with the DTML Method's Id. Want to understand this? Read on.

    Getting Physical

    The first half of virtual hosting is rewriting incoming URIs into physical paths. Many people run ZServer behind Apache, or another HTTP server with rewriting capabilities, or a proxy. In these cases, you can tell the front-end HTTP server to rewrite 'http://www.hotsite.com/(.*)' to '/blah/cgi/Zope.cgi/hotsite/$1', for example.

    This works perfectly well, but if your clients are connecting directly to ZServer, or if you would like to keep all of the virtual hosting logic in Zope, you will need to do your rewriting in an Access Rule.

    An Access Rule is just a regular method (DTML Method or Document, External Method, Python Method, etc.) on which you have used SiteAccess' "Set Access Rule" method. In this case, the method lives in the root, so it will examine every incoming request and decide how to deal with it.

    The example DTML Method above is the simplest kind of rewrite rule, forcing all requests to traverse the 'hotsite' object before any others in the URI.

    Getting Logical

    The second, and more difficult, half of virtual hosting is getting your Zope objects to generate correct logical URIs for links and images. For example, if you are rewriting hotsite as described above, then a standard DTML snippet such as 
    <a href="&dtml-URL;/hottopics">
    in object '/hotsite/forum' will generate 
    <a href="http://www.hotsite.com/hotsite/forum/hottopics">
rather than
<a href="http://www.hotsite.com/forum/hottopics">
    To prevent this, all of the URLn and BASEn request variables and the absolute_url() method need to be told to strip off '/hotsite'. That's what SiteRoot objects do.

    A SiteRoot object should be placed in the physical root folder ('/hotsite', in this case) and told the logical URL at which to base all requests passing through this folder. You tell it by setting its Path property, which in this case should have the value '/'.

    For flexibility's sake, Path can also be set as a property 'SiteRootPATH' of the '/hotsite' folder or of the root folder, or it can be set in the rewriting Access Rule with a call to "REQUEST.set('SiteRootPATH', '/')", or it can be passed in from the mediating web server as an environment variable. You can also provide a Base ('SiteRootBASE') value, which will then replace the host:port/script portion of URIs.

    Example 2: Multiple Sites

    Suppose we are hosting 'hotsite.net', 'fooflowers.com', and 'openmouths.org' from '/hotsite', '/foof', and '/openm' respectively. We are distinguishing requests via HTTP_HOST, and we don't care what subdomain or port was specified.

    Put a SiteRoot in each of '/hotsite', '/foof', and '/openm'. In each one, erase the default Path and leave Base blank. Make a DTML Method in the root folder containing 
    Extract the part of HTTP_HOST we care about, and declare our rewrite dictionary.
<dtml-let hostname="_.string.join(_.string.split(_.string.split(HTTP_HOST, ':')[0], '.')[-2:], '.')"
          sitemap="{'hotsite.net': 'hotsite',
                    'fooflowers.com': 'foof',
                    'openmouths.org': 'openm'}">
    Do we have a match?
    <dtml-if expr="sitemap.has_key(hostname)">
Set the logical root: <dtml-call "REQUEST.set('SiteRootPATH', '/')">
Add physical root: <dtml-call "REQUEST['TraversalRequestNameStack'].append(sitemap[hostname])">
    </dtml-if>
</dtml-let>
    Use "Set Access Rule" with the DTML Method's Id. An almost identical method can be used to distinguish sites by SERVER_ADDRESS and SERVER_PORT instead of HTTP_HOST. In that case, though, you would probably add a line to set the appropriate SiteRootBASE.

    If you wanted all of these virtual hosts' root folders to live in the folder 'vhosts', you could add the line: 
    Add vhost root: <dtml-call "REQUEST['TraversalRequestNameStack'].append('vhosts')">
    after the 'Add physical root' line. If you wanted to add multiple path elements for each site, you could use path.extend instead of path.append and map 'fooflowers.org', for example, to ['foof', 'f', 'comsites']. This would place the root of fooflowers in folder '/comsites/f/foof/'.

    Minor Notes

    • The return value of an Access Rule is ignored and discarded. This allows embedded string comments such as in the examples above, and the use of <dtml-return " 'ignored' "> to exit the Rule. It also means that if you want to redirect within an Access Rule, you must use <dtml-raise type="Redirect"> instead of "RESPONSE.redirect()"
    • A SiteRoot object is essentially an Access Rule which calls
      REQUEST.setServerURL(SiteRootBASE) and REQUEST.setVirtualRoot(SiteRootPATH).
    • You might want to exempt management access from being affected by the virtual hosting. One way to do this is to have a 'magic folder' start all management interactions. I use 'Z', and wrap the rest of the Access Rule code in something like:

    • If a SiteRooted folder is ever accessed through URLs with a base or path that does not get rewritten to match the Base and Path of the SiteRoot, you should make the SiteRoot's Base and Path blank and dynamically create SiteRootPATH/SiteRootBASE variables. For example, if you made a 'Zope' global-access prefix as described above, then the 'else' part should contain something like <dtml-call "REQUEST.set('SiteRootPATH', '/')">.

    Must Upgrade

    If your site has SiteAccess 1 objects in it, you must upgrade them. Until you do, they will be inert

    From the command line

    Copy 'updata.py' from the 'Extensions' directory of the SiteAccess Product to the 'lib/python' directory. Run it there, then delete it.

    From an External Method

    In the Zope root folder, add an External Method with method "updata" and python file "SiteAccess.updata". Click on the "Try It" tab, then delete it.

    zope2.13-2.13.21/source/Zope2/src/Products/SiteAccess/doc/otheruse.html0000644000175000017500000000452612214017422024351 0ustar arnauarnau Other Uses of Access Rules

    Embedded Session Values

    Sometimes it would be nice to be able to embed a variable/value in the middle of a URL, rather than having to tack a query string onto the end. It can be essential, such as when you want parameterized pages to be spiderable (spiders don't like query strings).

    One way to accomplish this is with an Access Rule. For example, suppose we created a Zope folder called 'Session', containing the following DTML Method Access Rule: 
    <dtml-let stack="REQUEST['TraversalRequestNameStack']">
Don't intercept management requests
<dtml-unless "stack[0][:6]=='manage'">
  Is the next path segment a positive integer?
  <dtml-if "_.int(stack[-1])>0">
    Save it and remove it from the path
    <dtml-call "REQUEST.set('SessionID', stack.pop())">
    Add it back into the logical path
    <dtml-call "REQUEST.setVirtualRoot(REQUEST.steps+[SessionID])">
  <dtml-else>
    <dtml-raise type="Invalid">Invalid Session ID!</dtml-raise>
  </dtml-if>
</dtml-unless>
</dtml-let>
    Then the request URI 'http://www.mysite.com/foo/Session/84076/step3' will publish the Zope object at '/foo/Session/step3', with variable 'SessionID' set to '84076'. Thanks to acquisition, 'step3' doesn't need to be in 'Session'. 'Session' may be empty except for the Access Rule, or it may contain session-management objects.

    When writing this kind of Access Rule, it is useful to remember the following:
    • REQUEST['TraversalRequestNameStack'] is the stack of Ids yet to be traversed.
    • REQUEST.steps is the list of Ids already traversed.
    • You can manipulate the path stack with append, insert, pop, and similar list operations.
    • You should not manipulate 'steps', instead using REQUEST.setVirtualRoot('path') to alter the apparent traversal history and URL generation.

It must be unpacked in the Products directory, for better compatibility with INSTANCE_HOME installations. 2000-03-21 Evan Simpson * Version 1.0.1 * Fix for FTP incompatibility * Match changes in Zope 2.1.5/6 2000-01-18 Evan Simpson * Version 1.0.0 * Decided that it's been long enough to call it stable * Eliminated stale _v_absolute_url attributes (thanks to Wade Simmons) * Killed peculiar and obscure interaction with ZCatalog 1999-12-15 Evan Simpson * Version 0.2.0 * Got absolute_url to do the right thing under both Zope 2.0 and 2.1. Note that this will change 2.0's behavior to match 2.1 1999-11-19 Evan Simpson * Added COPYRIGHT.txt, making Wide Open Source licence (BSD-style) explicit. (Mike Goldman provided the text, I provided the silly name). 1999-11-18 Evan Simpson * Version 0.1.4 * BASE tags generated for default pages should play nicely with setURL(base=...) * Setting the base but not the path works now. * Added ./doc/ directory with copies of documentation from Zope.org * SiteRoot* variables set in the environment are now seen. 1999-10-29 Evan Simpson * Version 0.1.3 * Using DTML Docs/Methods as Access Rules should work better, and allow normal acquisition. You won't have permissions for anything unless you give the rule a Proxy Role, though. * __no_before_traverse__ at the start of a URL path now persists in generated URLs, making debugging easier. 1999-10-27 Evan Simpson * Version 0.1.2 * Fixed absolute_url() of objects acquired from above the point at which setURL was called (usually by a SiteRoot). (thanks again to Bruce Perens and technocrat.net) * Added Base and Path properties to SiteRoot, with Path defaulting to '/', the most commonly used value. If these are blank, it will search for SiteRootBASE and SiteRootPATH. * REQUEST.setURL now accepts either a string or sequence of strings for its path argument. 1999-10-24 Evan Simpson * Version 0.1.1 * Made Access Rules work on unadorned root path (thanks to Bruce Perens) * Reorganized REQUEST.traverse to better handle changes to the path within the loop. * Experimental change: Overrides icon of methods designated as Access Rules to provide visual feedback. This is a fragile hack, but relatively harmless if it fails. (suggested by Evan Gibson) * Fixed Acquisition of SiteRoot* values (thanks to Oleg Broytmann) * Rationalized file permissions (thanks to Joshua Brauer) 1999-10-19 Evan Simpson * Version 0.1.0 * First (apparently) working version * Implemented REQUEST.setURL(base, path) and made SiteRoot use it. * Put a link to existing AccessRule on "Add AccessRule" page. zope2.13-2.13.21/source/Zope2/src/Products/SiteAccess/version.txt0000644000175000017500000000002112214017422023270 0ustar arnauarnauSiteAccess-2-0-0 zope2.13-2.13.21/source/Zope2/src/Products/ZReST/0000755000175000017500000000000012214017422017772 5ustar arnauarnauzope2.13-2.13.21/source/Zope2/src/Products/ZReST/TODO.txt0000644000175000017500000000031012214017422021272 0ustar arnauarnau. charset configuration, defaulting to 'latin-1' . add "level" and "header" args to render / as_html - level indicates the header level to start at - header boolean turns page header tags on/off zope2.13-2.13.21/source/Zope2/src/Products/ZReST/ZReST.py0000644000175000017500000002441512214017422021321 0ustar arnauarnau''' ReStructuredText Product for Zope This Product stores two texts - a "source" text in ReStructureText format, and a HTML "formatted" version of that text.

An instance of this class is found in the default Zope installation at /temp_folder/session_data. The TransientObjectContainer (TOC) holds Transient Objects (TOs). A TO is obtained via its container via a call to TOC.new_or_existing(key), where "key" is usually the "browser id" associated with a visitor (See Products.Session.BrowserIdManager). If the TOC has a "current" TO corresponding to "key", it is returned. If the TOC does not have a "current" TO corresponding to "key", (due to the expiration of the TO or because it never existed in the first place) a "new" TO is manufactured and returned. Timeslices Transience defines the notion of a "timeslice". A "timeslice" is an integer that represents some "slice" of time, defined by a "period". For example, if a period is 20 seconds long, three ordered time slices might be expressed as 0, 20, and 40. The next timeslice would be 60, and so on. For an absolute time to "belong" to a timeslice, it would need to be equal to or greater than one timeslice integer, but less than the subsequent timeslice integer. Data Structures Maintained by a Transient Object Container The TOC maintains three important kinds of data structures: - a "_data" structure, which is an IOBTree mapping a "timeslice" integer to a "bucket" (see next bullet for definition of bucket). - One or more "buckets", which are OOBTree objects which map a "key" (usually browser id) to a TransientObject. Buckets are stored inside of the "_data" structure. There is a concept of a "current" bucket, which is the bucket that is contained within the _data structured with a key equal to the "current" timeslice. A current bucket must always exist (this is an invariant). - A "max_timeslice" integer, which is equal to the "largest" timeslice for which there exists a bucket in the _data structure. This is an optimization given that key operations against BTrees can be slow and could cause conflicts (the same could be achieved via _data.maxKey() otherwise). When a Transient Object is created via new_or_existing, it is added to the "current" bucket. As time goes by, the bucket to which the TO was added ceases to be the "current" bucket. If the transient object is "accessed" (it is called up out of the TOC via the TOC's 'get' method), it is again moved to the "current" bucket defined by the current time's timeslice. During the course of normal operations, a TransientObject will move from an "old" bucket to the "current" bucket many times, as long as it continues to be accessed. It is possible for a TransientObject to never expire, as long as it is called up out of its TOC often enough. If a TransientObject is not accessed in the period of time defined by the TOC's "timeout", it is eventually garbage collected. How the TransientObjectContainer Determines if a TransientObject is "Current" All "current" timeslice buckets (as specified by the timeout) are searched for the transient object, most recent bucket first. Housekeeping: Finalization, Garbage Collection, and Bucket Replentishing The TOC performs "finalization", "garbage collection", and "bucket replentishing". It typically performs these tasks "in-band" (although it is possible to do the housekeeping tasks "out of band" as well: see the methods of the Transient Object Container with "housekeep" in their names). "In band" housekeeping implies that the TOC does not maintain a separate thread or process that wakes up every so often to clean up. Instead, during the course of normal operations, the TOC opportunistically performs housekeeping functions. Finalization is defined as optionally calling a function at bucket expiration time against all transient objects contained within that bucket. The optional function call is user-defined, but it is managed by the "notifyDel" method of the TOC. Garbage collection is defined as deleting "expired" buckets in the _data structure (the _data structure maps a timeslice to a bucket). Typically this is done by throwing away one or more buckets in the _data structure after they expire. Bucket replentishing is defined as the action of (opportunistically) creating more buckets to insert into the the _data structure, replacing ones that are deleted during garbage collection. The act of deleting a bucket does not necessarily imply that a new bucket will be immediately created thereafter. We create new buckets in batches to reduce the possibility of conflicts. Finalization is attempted on every call to the transience machinery to make TOs appear to expire "on time". Garbage collection and replentishment is performed on a somewhat random basis to avoid unnecessary conflicts. Goals - A low number of ZODB conflict errors (which reduce performance). - Stability. To Do - Testing under ZEO. zope2.13-2.13.21/source/Zope2/src/Products/Transience/TransientObject.py0000644000175000017500000002276512214017422024602 0ustar arnauarnau############################################################################## # # Copyright (c) 2002 Zope Foundation and Contributors. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

They implement the following interfaces: - ItemWithId - StringKeyedHomogenousItemContainer - TransientItemContainer In particular, one uses the 'new_or_existing' method on TransientObjectContainers to retrieve or create a TransientObject based on a given string key. If add or delete notifications are registered with the container, they will be called back when items in the container are added or deleted, with the item and the container as arguments. The callbacks may be registered either as bound methods, functions, or physical paths to Zope Script (Python Script or External Method) objects (e.g. '/some/resolvable/script/name'). In any of these cases, the delete and add notifications will be called with arguments allowing the callbacks to operate on data representing the state of the transient object at the moment of addition or deletion (see setAddNotificationTarget and setDelNotificationTarget below). TransientObjects are containerish items held within TransientObjectContainers and they implement the following interfaces: - ItemWithId - Transient - DictionaryLike - TTWDictionary - ImmutablyValuedMappingOfPickleableObjects Of particular importance is the idea that TransientObjects do not offer the contract of "normal" ZODB container objects; mutations made to items which are contained within a TransientObject cannot be expected to persist. Developers need explicitly resave the state of a subobject of a TransientObject by placing it back into the TransientObject via the TransientObject.__setitem__ or .set methods. This requirement is due to the desire to allow people to create alternate TransientObject implementations that are *not* based on the ZODB. Practically, this means that when working with a TransientObject which contains mutable subobjects (even if they inherit from Persistence.Persistent), you *must* resave them back into the TransientObject. For example:: class Foo(Persistence.Persistent): pass transient_object = transient_data_container.new('t') foo = transient_object['foo'] = Foo() foo.bar = 1 # the following is *necessary* to repersist the data transient_object['foo'] = foo """ from zope.interface import Interface class Transient(Interface): def invalidate(): """ Invalidate (expire) the transient object.

Items placed into transient object must have string keys, but may have any type of value. Common Usages A Transient Object Container is used by Session Data Managers to store session data. To create a Transient Object Container, specify the following: - **Id** The Zope id of the Transient Object Container. - **Title** *Optional* The title of the object. - **Data object timeout (in minutes)** The minimum number of minutes that objects in the container will persist for. Objects in the container are passively deleted, so they may not be deleted exactly after this number of minutes elapses. A setting of "0" indicates that objects should not expire. - **Timeout resolution (in seconds)** Defines what the "resolution" of item timeout is. Setting this higher allows the transience machinery to do fewer "writes" at the expense of causing items to time out later than the "Data object timeout value" by a factor of (at most) this many seconds. This number must divide evenly into the number of timeout seconds ("Data object timeout value" * 60) and cannot be set higher than the timeout value in seconds. - **Maximum number of subobjects ** The maximum number of subobjects that this container may simultaneously hold. Since transient objects normally hold session data, this number is this is the effective limit for the number of simultaneous sessions. If the value is "0", the number of objects addable to the container will be not be artificially limited. Note: This setting is useful to prevent accidental or deliberate denial of service due to RAM shortage if the transient object container is instantiated in a storage which is backed solely by RAM, such as a Temporary Folder. - **Script to call when objects are added** *Optional* The physical path of of a Zope script which will receive notifications when objects are added to the Transient Object Container. Ex: '/path/to/add/script'. For more information, see "Add and Delete Scripts" below. - **Script to call when objects are deleted** *Optional* The physical path of a Zope script which will receive notifications when objects are deleted from the Transient Object Container, either explicitly or through timeout-related expiration. Ex: '/path/to/delete/script' For more information, see "Add and Delete Scripts" below. Add and Delete Scripts Add and Delete scripts are Zope scripts which are called, respectively, when an object is added or removed from a Transient Object Container. An add or delete script is specified by naming it by its full Zope object path with slash separators, e.g. "/path/to/method". Add and delete scripts are called with two arguments. The first argument is the item being added or removed from the container; the second argument is the Transient Object Container itself. The container will be acquisition wrapped, allowing the it to be used as a context to reference other Zope objects.

    Transient Object Containers are used to store transient data. Transient data will persist, but only for a user-specified period of time (the "data object timeout") after which it will be flushed.

    1 item is in this transient object container. &dtml-l; items are in this transient object container. There are no items in this transient object container.

    Title
    Data object timeout value (in minutes)
    ("0" means no expiration)
    Timeout resolution (in seconds)
    Defines what the "resolution" of item timeout is. Setting this higher allows the transience machinery to do fewer "writes" at the expense of causing items to time out later than the "Data object timeout value" by a factor of (at most) this many seconds. This number must divide evenly into the number of timeout seconds ("Data object timeout value" * 60) and cannot be set higher than the timeout value in seconds.
    Maximum number of subobjects
    ("0" means infinite)
    Script to call when objects are added
    (e.g. "/somefolder/addScript")
    Script to call when objects are deleted
    (e.g. "/somefolder/delScript")

    WARNING! All data objects existing in this transient object container will be deleted when the data object timeout or expiration resolution is changed.

    Transient Object Containers are used to store transient data. Transient data will persist, but only for a user-specified period of time, (the "data object timeout") after which it will be flushed.

    It is recommended that Transient Object Containers be added to storages which do not support undo operations; transient objects are write-intensive; their use may cause many undoable transactions, potentially bloating undoing ZODB databases.

    Transient Object Containers support Add and Delete Scripts which are methods which are invoked when transient objects are added or deleted from the container. A add/delete script is invoked with the item being operated upon and the transient object container as arguments. Specify the Zope physical path to the method to be invoked to receive the notification (e.g. '/folder/add_notifier').

    Here are some examples of Zope Page Template use:
    Image Batches This example displays images in batches of three. One of the images has View permission turned off, so this also demonstrates error handling and skip_unauthorized.
    Macro Usage This example uses a full-page macro, and uses a paragraph macro twice.
    Object Tree This example uses the SimpleTreeMaker to simulate the ZMI left panel tree.
    Object Access and HTML This example accesses several objects and shows the difference between structure and text insertion.

You can define two different kinds of TAL variables: local and global. When you define a local variable in a statement element, you can only use that variable in that element and the elements it contains. If you redefine a local variable in a contained element, the new definition hides the outer element's definition within the inner element. When you define a global variables, you can use it in any element processed after the defining element. If you redefine a global variable, you replace its definition for the rest of the template. *Note: local variables are the default* If the expression associated with a variable evaluates to *nothing*, then that variable has the value *nothing*, and may be used as such in further expressions. Likewise, if the expression evaluates to *default*, then the variable has the value *default*, and may be used as such in further expressions. Examples Defining a global variable:: tal:define="global company_name string:Zope Corp, Inc."

It replaces the statement element with either text or a structure (unescaped markup). The body of the statement is an expression with an optional type prefix. The value of the expression is converted into an escaped string if you prefix the expression with 'text' or omit the prefix, and is inserted unchanged if you prefix it with 'structure'. Escaping consists of converting "&" to "&amp;", "<" to "&lt;", and ">" to "&gt;". If the value is *nothing*, then the element is simply removed. If the value is *default*, then the element is left unchanged. Examples The two ways to insert the title of a template:: Title Title Inserting HTML/XML::

If its expression evaluates to a *true* value, then normal processing of the element continues, otherwise the statement element is immediately removed from the template. For these purposes, the value *nothing* is false, and *default* has the same effect as returning a true value. *Note: Zope considers missing variables, None, zero, empty strings, and empty sequences false; all other values are true.* Examples Test a variable before inserting it (the first example tests for existence and truth, while the second only tests for existence)::

The string can contain variable substitutions of the form '$name' or '${path}', where 'name' is a variable name, and 'path' is a "path expression":tales-path.stx.

Template Text The text in a template must be well-formed HTML if the content type is 'text/html'. Otherwise, it must be well-formed XML. Either way, it may include "TAL":tal.stx or "METAL":metal.stx markup containing "TALES":tales.stx expressions. Controls 'Title' -- Allows you to specify the Zope title of the template. 'Content-Type' -- Allows you to specify the content-type that will be given to renderings of this template. Also, if the content type is 'text/html' (the default) then the template is assumed to contain HTML, not XML. This affects both parsing and rendering of the template, and can be overridden by giving the template an 'is_html' property. In HTML mode you don't need to explicitly declare 'tal' and 'metal' XML namespaces. In XML mode you must explicitly declare 'tal' and 'metal' XML namespaces, and Zope assumes that your template contains well-formed XML. 'Expand macros when editing' -- Allows you to turn the expansion of METAL macros on or off. This only affects viewing of the source code, not rendering. Buttons and Other Form Elements 'Save Changes' -- saves changes you make to the body, title, or content type. 'Taller'/'Shorter'/'Wider'/'Narrower' -- make the body textarea taller, shorter, wider, or narrower. 'File' -- upload a file into this template.

If the expression supplied does not evaluate to a boolean value, *not* will issue a warning and *coerce* the expression's value into a boolean type based on the following rules: 1. the number 0 is *false* 2. numbers > 0 are *true* 3. an empty string or other sequence is *false* 4. a non-empty string or other sequence is *true* 5. a *non-value* (e.g. void, None, Nil, NULL, etc) is *false* 6. all other values are implementation-dependent. If no expression string is supplied, an error should be generated. Zope considers all objects not specifically listed above as *false* (including negative numbers) to be *true*.

TALES is *one* possible expression syntax for these languages, but they are not bound to this definition. Similarly, TALES could be used in a context having nothing to do with TAL or METAL. TALES expressions are described below with any delimiter or quote markup from higher language layers removed. Here is the basic definition of TALES syntax:: Expression ::= [type_prefix ':'] String type_prefix ::= Name Here are some simple examples:: a/b/c path:a/b/c nothing path:nothing python: 1 + 2 string:Hello, ${user/getUserName} The optional *type prefix* determines the semantics and syntax of the *expression string* that follows it. A given implementation of TALES can define any number of expression types, with whatever syntax you like. It also determines which expression type is indicated by omitting the prefix. If you do not specify a prefix, Zope assumes that the expression is a *path* expression. TALES Expression Types These are the TALES expression types supported by Zope: * "path":tales-path.stx expressions - locate a value by its path. * "exists":tales-exists.stx expressions - test whether a path is valid. * "nocall":tales-nocall.stx expressions - locate an object by its path. * "not":tales-not.stx expressions - negate an expression * "string":tales-string.stx expressions - format a string * "python":tales-python.stx expressions - execute a Python expression Built-in Names These are the names that always available to TALES expressions in Zope: - *nothing* - special value used by to represent a *non-value* (e.g. void, None, Nil, NULL). - *default* - special value used to specify that existing text should not be replaced. See the documentation for individual TAL statements for details on how they interpret *default*. - *options* - the *keyword* arguments passed to the template. These are generally available when a template is called from Methods and Scripts, rather than from the web. - *repeat* - the 'repeat' variables; see the "tal:repeat":tal-repeat.stx documentation. - *attrs* - a dictionary containing the initial values of the attributes of the current statement tag. - *CONTEXTS* - the list of standard names (this list). This can be used to access a built-in variable that has been hidden by a local or global variable with the same name. - *root* - the system's top-most object: the Zope root folder. - *here* - the object to which the template is being applied. - *container* - The folder in which the template is located. - *template* - the template itself. - *request* - the publishing request object. - *user* - the authenticated user object. - *modules* - a collection through which Python modules and packages can be accessed. Only modules which are approved by the Zope security policy can be accessed. Note the names 'root', 'here', 'container', 'template', 'request', 'user', and 'modules' are optional names supported by Zope, but are not required by the TALES standard.

The statement expression describes a macro definition. In Zope the expression will generally be a path expression referring to a macro defined in another template. See "metal:define-macro" for more information. The effect of expanding a macro is to graft a subtree from another document (or from elsewhere in the current document) in place of the statement element, replacing the existing sub-tree. Parts of the original subtree may remain, grafted onto the new subtree, if the macro has *slots*. See "metal:define-slot":metal-define-slot.stx for more information. If the macro body uses any macros, they are expanded first. When a macro is expanded, its 'metal:define-macro' attribute is replaced with the 'metal:use-macro' attribute from the statement element. This makes the root of the expanded macro a valid 'use-macro' statement element. Examples Basic macro usage::

    header macro from defined in other.html template

    This example refers to the 'header' macro defined in the 'other.html' template which is in the same folder as the current template. When the macro is expanded, the 'p' element and its contents will be replaced by the macro. Note: there will still be a 'metal:use-macro' attribute on the replacement element. See Also "metal:define-macro":metal-define-macro.stx "metal:fill-slot":metal-fill-slot.stx zope2.13-2.13.21/source/Zope2/src/Products/PageTemplates/help/tal-on-error.stx0000644000175000017500000000374612214017422025601 0ustar arnauarnauon-error: Handle errors Syntax 'tal:on-error' syntax:: argument ::= (['text'] | 'structure') expression Description The 'tal:on-error' statement provides error handling for your template. When a TAL statement produces an error, the TAL interpreter searches for a 'tal:on-error' statement on the same element, then on the enclosing element, and so forth. The first 'tal:on-error' found is invoked. It is treated as a 'tal:content' statement. A local variable 'error' is set. This variable has these attributes: 'type' -- the exception type 'value' -- the exception instance 'traceback' -- the traceback object The simplest sort of 'tal:on-error' statement has a literal error string or *nothing* for an expression. A more complex handler may call a script that examines the error and either emits error text or raises an exception to propagate the error outwards. Examples Simple error message:: Ishmael Removing elements with errors:: Ishmael Calling an error-handling script::
    ...
    Here's what the error-handling script might look like:: ## Script (Python) "errHandler" ##bind namespace=_ ## error=_['error'] if error.type==ZeroDivisionError: return "

The expression should evaluate to a sequence. If the sequence is empty, then the statement element is deleted, otherwise it is repeated for each value in the sequence. If the expression is *default*, then the element is left unchanged, and no new variables are defined. The 'variable_name' is used to define a local variable and a repeat variable. For each repetition, the local variable is set to the current sequence element, and the repeat variable is set to an iteration object. Repeat Variables You use repeat variables to access information about the current repetition (such as the repeat index). The repeat variable has the same name as the local variable, but is only accessible through the built-in variable named 'repeat'. The following information is available from the repeat variable: o *index* - repetition number, starting from zero. o *number* - repetition number, starting from one. o *even* - true for even-indexed repetitions (0, 2, 4, ...). o *odd* - true for odd-indexed repetitions (1, 3, 5, ...). o *start* - true for the starting repetition (index 0). o *end* - true for the ending, or final, repetition. o *first* - true for the first item in a group - see note below o *last* - true for the last item in a group - see note below o *length* - length of the sequence, which will be the total number of repetitions. o *letter* - repetition number as a lower-case letter: "a" - "z", "aa" - "az", "ba" - "bz", ..., "za" - "zz", "aaa" - "aaz", and so forth. o *Letter* - upper-case version of *letter*. o *roman* - repetition number as a lower-case roman numeral: "i", "ii", "iii", "iv", "v", etc. o *Roman* - upper-case version of *roman*. You can access the contents of the repeat variable using path expressions or Python expressions. In path expressions, you write a three-part path consisting of the name 'repeat', the statement variable's name, and the name of the information you want, for example, 'repeat/item/start'. In Python expressions, you use normal dictionary notation to get the repeat variable, then attribute access to get the information, for example, "python:repeat['item'].start". Note that 'first' and 'last' are intended for use with sorted sequences. They try to divide the sequence into group of items with the same value. If you provide a path, then the value obtained by following that path from a sequence item is used for grouping, otherwise the value of the item is used. You can provide the path by passing it as a parameter, as in "python:repeat['item'].first('color')", or by appending it to the path from the repeat variable, as in "repeat/item/first/color". Examples Iterating over a sequence of strings::

    Inserting a sequence of table rows, and using the repeat variable to number the rows::
    1 Widget $1.50
    Nested repeats::
    1 * 1 = 1
    Insert objects. Seperates groups of objects by meta-type by drawing a rule between them::

    Meta Type

    Note, the objects in the above example should already be sorted by meta-type. zope2.13-2.13.21/source/Zope2/src/Products/PageTemplates/help/tales-path.stx0000644000175000017500000000536412214017422025320 0ustar arnauarnauTALES Path expressions Syntax Path expression syntax:: PathExpr ::= Path [ '|' Path ]* Path ::= variable [ '/' URL_Segment ]* variable ::= Name Description A path expression consists of one or more *paths* separated by vertical bars (|). A path consists of one or more non-empty strings separated by slashes. The first string must be a variable name (built-in variable or a user defined variable), and the remaining strings, the *path segments*, may contain letters, digits, spaces, and the punctuation characters underscore, dash, period, comma, and tilde. For example:: request/cookies/oatmeal nothing here/some-file 2001_02.html.tar.gz/foo root/to/branch | default request/name | string:Anonymous Coward When a path expression is evaluated, Zope attempts to traverse the path, from left to right, until it succeeds or runs out of paths segments. To traverse a path, it first fetches the object stored in the variable. For each path segment, it traverses from the current object to the subobject named by the path segment. Subobjects are located according to standard Zope traversal rules (via getattr, getitem, or traversal hooks). Once a path has been successfully traversed, the resulting object is the value of the expression. If it is a callable object, such as a method or template, it is called. If a traversal step fails, evaluation immediately proceeds to the next path. If there are no further paths, an error results. The expression in a series of paths seperated by vertical bars can be any TALES expression. For example, 'request/name | string:Anonymous Coward'. This is useful chiefly for providing default values such as strings and numbers which are not expressable as path expressions. If no path is given the result is *nothing*. Since every path must start with a variable name, you need a set of starting variables that you can use to find other objects and values. See the "TALES overview":tales.stx for a list of built-in variables. Since variable names are looked up first in locals, then in globals, then in this list, these names act just like built-ins in Python; They are always available, but they can be shadowed by a global or local variable declaration. You can always access the built-in names explicitly by prefixing them with *CONTEXTS*. (e.g. CONTEXTS/root, CONTEXTS/nothing, etc).

When a macro is used, its slots can be replaced, in order to customize the macro. Slot definitions provide default content for the slot. You will get the default slot contents if you decide not to customize the macro when using it. The 'metal:define-slot' statement must be used inside a 'metal:define-macro' statement. Slot names must be unique within a macro. Examples Simple macro with slot::

    Hello World

    This example defines a macro with one slot named 'name'. When you use this macro you can customize the 'b' element by filling the 'name' slot.

The macro is named by the statement expression, and is defined as the element and its sub-tree. In Zope, a macro definition is available as a sub-object of a template's 'macros' object. For example, to access a macro named 'header' in a template named 'master.html', you could use the path expression 'master.html/macros/header'. Examples Simple macro definition::

If its expression evaluates to a *false* value, then normal processing of the element continues and the tag is not omitted. If the expression evaluates to a *true* value, or there is no expression, the statement tag is replaced with its contents. Zope treats empty strings, empty sequences, zero, None, *nothing*, and *default* at false. All other values are considered true. Examples Unconditionally omitting a tag::

It can be used in conjunction with or independently of "TAL":tal.stx and "TALES":tales.stx. Macros provide a way to define a chunk of presentation in one template, and share it in others, so that changes to the macro are immediately reflected in all of the places that share it. Additionally, macros are always fully expanded, even in a template's source text, so that the template appears very similar to its final rendering. METAL Namespace The METAL namespace URI and recommended alias are currently defined as:: xmlns:metal="http://xml.zope.org/namespaces/metal" Just like the TAL namespace URI, this URI is not attached to a web page; it's just a unique identifier. Zope does not require an XML namespace declaration when creating templates with a content-type of 'text/html'. However, it does require an XML namespace declaration for all other content-types. METAL Statements METAL defines a number of statements: * "metal:define-macro":metal-define-macro.stx - Define a macro. * "metal:use-macro":metal-use-macro.stx - Use a macro. * "metal:define-slot":metal-define-slot.stx - Define a macro customization point. * "metal:fill-slot":metal-fill-slot.stx - Customize a macro. Although METAL does not define the syntax of expression non-terminals, leaving that up to the implementation, a canonical expression syntax for use in METAL arguments is described in "TALES Specification":tales.stx. See Also "TAL Overview":tal.stx "TALES Overview":tales.stx "metal:define-macro":metal-define-macro.stx "metal:use-macro":metal-use-macro.stx "metal:define-slot":metal-define-slot.stx "metal:fill-slot":metal-fill-slot.stx zope2.13-2.13.21/source/Zope2/src/Products/PageTemplates/help/tales-exists.stx0000644000175000017500000000132712214017422025676 0ustar arnauarnauTALES Exists expressions Syntax Exists expression syntax:: exists_expressions ::= 'exists:' path_expression Description Exists expressions test for the existence of paths. An exists expression returns true when the path expressions following it expression returns a value. It is false when the path expression cannot locate an object. Examples Testing for the existence of a form variable::

    Please enter a number between 0 and 5

    Note that in this case you can't use the expression, 'not:request/form/number', since that expression will be true if the 'number' variable exists and is zero. zope2.13-2.13.21/source/Zope2/src/Products/PageTemplates/help/tales-python.stx0000644000175000017500000000702012214017422025674 0ustar arnauarnauTALES Python expressions Syntax Python expression syntax:: Any valid Python language expression Description Python expressions evaluate Python code in a security-restricted environment. Python expressions offer the same facilities as those available in Python-based Scripts and DTML variable expressions. Security Restrictions Python expressions are subject to the same security restrictions as Python-based scripts. These restrictions include: access limits -- Python expressions are subject to Zope permission and role security restrictions. In addition, expressions cannot access objects whose names begin with underscore. write limits -- Python expressions cannot change attributes of Zope objects. Despite these limits malicious Python expressions can cause problems. See The Zope Book for more information. Built-in Functions Python expressions have the same built-ins as Python-based Scripts with a few additions. These standard Python built-ins are available: 'None', 'abs', 'apply', 'callable', 'chr', 'cmp', 'complex', 'delattr', 'divmod', 'filter', 'float', 'getattr', 'hash', 'hex', 'int', 'isinstance', 'issubclass', 'list', 'len', 'long', 'map', 'max', 'min', 'oct', 'ord', 'repr', 'round', 'setattr', 'str', 'tuple'. The 'range' and 'pow' functions are available and work the same way they do in standard Python; however, they are limited to keep them from generating very large numbers and sequences. This limitation helps protect against denial of service attacks. Finally, these functions are available in Python expressions, but not in Python-based scripts: 'path(string)' -- Evaluate a TALES "path":tales-path.stx expression. 'string(string)' -- Evaluate a TALES "string":tales-string.stx expression. 'exists(string)' -- Evaluates a TALES "exists":tales-exists.stx expression. 'nocall(string)' -- Evaluates a TALES "nocall":tales-nocall.stx expression. Python Modules A number of Python modules are available by default. You can make more modules available. You can access modules either via path expressions (for example 'modules/string/join') or in Python with the 'modules' mapping object (for example 'modules["string"].join'). Here are the default modules: 'string' -- The standard "Python string module":http://www.python.org/doc/current/lib/module-string.html. Note: most of the functions in the module are also available as methods on string objects. 'random' -- The standard "Python random module":http://www.python.org/doc/current/lib/module-random.html. 'math' -- The standard "Python math module":http://www.python.org/doc/current/lib/module-math.html. Examples Using a module usage (pick a random choice from a list):: a random number between one and five String processing (capitalize the user name)::

The 'metal:fill-slot' statement must be used inside a 'metal:use-macro' statement. Slot names must be unique within a macro. If the named slot does not exist within the macro, the slot contents will be silently dropped. Examples Given this macro::

    Hello World

    You can fill the 'name' slot like so::

    Hello Kevin Bacon

The statement argument is exactly like that of 'tal:replace', and is interpreted in the same fashion. If the expression evaluates to *nothing*, the statement element is left childless. If the expression evaluates to *default*, then the element's contents are unchanged. *Note: The default replacement behavior is 'text'.* Examples Inserting the user name::

You can qualify an attribute name with a namespace prefix, for example 'html:table', if you are generating an XML document with multiple namespaces. The value of each expression is converted to a string, if necessary. If the expression associated with an attribute assignment evaluates to *nothing*, then that attribute is deleted from the statement element. If the expression evaluates to *default*, then that attribute is left unchanged. Each attribute assignment is independent, so attributes may be assigned in the same statement in which some attributes are deleted and others are left alone. If you use 'tal:attributes' on an element with an active 'tal:replace' command, the 'tal:attributes' statement is ignored. If you use 'tal:attributes' on an element with a 'tal:repeat' statement, the replacement is made on each repetition of the element, and the replacement expression is evaluated fresh for each repetition.

These include 'string', 'math', and 'random'. The only way to make other Python modules available for import is to add security declarations to them in the filesystem. MyScriptModules The simplest way to allow import of a module is to create your own simple custom Product. To make this Product: 1. Create a subdirectory of your Zope installation's "Products" directory. The name of the directory doesn't really matter; Let's call it 'MyScriptModules'. 2. Create a file in this subdirectory called '__init__.py'. 3. Add the following lines to your '__init__.py':: from Products.PythonScripts.Utility import allow_module, allow_class from AccessControl import ModuleSecurityInfo, ClassSecurityInfo from AccessControl.class_init import InitializeClass 4. For each module to which you want to allow access, add security declarations in '__init__.py'. Security Declarations You will need to write different security declarations depending on how much of a module you want to expose. You should import the module at the Python command line, and use 'dir()' to examine its contents. Names starting with underscore ('_') may be safely ignored. Be wary of dangerous modules, such as 'sys' and 'os', which may be exposed by the module. You can handle a module, such as 'base64', that contains only safe functions by writing 'allow_module("module_name")'. To allow access to only some names, in a module with dangerous contents, you can write:: ModuleSecurityInfo('module_name').declarePublic('name1', 'name2', ...) If the module contains a class that you want to use, you will need to add the following:: from import allow_class() Certain modules, such as 'sha', provide extension types instead of classes. Security declarations typically cannot be added to extension types, so the only way to use this sort of module is to write a Python wrapper class, or use External Methods. zope2.13-2.13.21/source/Products.PythonScripts/src/Products/PythonScripts/help/PythonScript_edit.stx0000644000175000017500000001132012214017673032460 0ustar arnauarnauEdit View: Edit A Script (Python) Description This view allows you to edit the logic which composes a script in Python. Script instances execute in a restricted context, bounded by your user's privilege level in Zope, and certain global restrictions of all through-the-web code. For information about what you "can" and "cannot" do in a Script instance as opposed to non-through-the-web Python, see the API Reference documentation for "Script (Python)" in this help system. Controls 'Title' -- Allows you to specify the Zope title of the script. 'Id' -- Allows you to specify the id of the script. 'Parameter List' -- Enter function parameters for this script separated by commas. For example: *foo, bar, baz* Status Elements 'Bound Names' -- the names used by this script for bindings. You may use these names in the body of the script to refer to bound elements. The defaults are:: context -- the script's "parent" respective to acquisition. container -- the script's "parent" respective to containment. script -- the script object itself. traverse_subpath -- if the script is called directly from a URL, this is the portion of the URL path after the script's name, split at slash separators, into a list of strings. If the script was not called directly from a URL, this will be an empty list. Another possible name binding, to the "namespace" object, is not set by default. If this was set, if the Script was called from DTML, it would represent the namespace of the calling DTML object. More information about bindings can be found by visiting the help screens of the "Bindings" tab of a Script (Python) instance. Buttons and Other Form Elements 'Save Changes' -- saves changes you make to the body, title, or parameter list. 'Taller'/'Shorter'/'Wider'/'Narrower' -- make the body textarea taller, shorter, wider, or narrower. 'File' -- upload a file into this Script (Python) instance. File Upload Details Files uploaded into a Script (Python) instance may either consist only of the actual body of the function, or the file containing the function body may contain at its head a set of lines starting with "##" which describe bindings, parameters, and the title. For example, a file uploaded into a Script (Python) instance might be simply:: return "Hello" If you upload this file into a Script (Python) instance, the existing settings (or default settings) for bindings, parameters, and title will remain. However, if you wished to, you could develop a Script (Python) on disk which looked like:: ## Script (Python) "foo" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters=goop, fudge ##title= ## return "Fudge was %s, goop was %s" % (fudge, goop) The lines preceded by "##" are metadata about the Script (Python) instance which can survive a round trip via FTP or through the web interface. When these lines are encountered by the parser after an upload (or webform save), they serve to *modify* the settings of the Script (Python) instance with the metadata contained within the blocked area. Lines beginning with "##" without any spaces after the "##" are contextually meaningful to the file upload parser. There are three keywords which can directly follow a "##": "bind", "parameters", and "title". The "bind" keyword following a "##" binds a name to a object in the context this Script (Python) instance's body. For example, the line "##bind container=goober" binds the name "goober" to the acquisition parent of the script, allowing you to refer to "goober" in the script body. Legal objects to which to bind are: container, context, namespace, script, and subpath. See the help available from the "bindings" tab of Script (Python) instances for more details about what bindings mean. The "title" keyword following a "##" provides a title to the script. E.g. "title=A Really Neat Script" The "parameters" keyword following a "##" provides parameters to the Script (Python) instance. E.g. "parameters=foo,bar,baz". zope2.13-2.13.21/source/Products.PythonScripts/src/Products/PythonScripts/help/standard.py0000644000175000017500000001052012214017673030420 0ustar arnauarnau""" Products.PythonScripts.standard: Utility functions and classes The functions and classes in this module are available from Python-based scripts, DTML, and Page Templates.

The following safety issues drive the need for secure Python Scripts: o Because many users can use Zope, a Python Script must make sure it does not allow a user to do something they are not allowed to do, like deleting an object they do not have permission to delete. Because of this requirement, Python Scripts do many security checks in the course of their execution. o Because Python Scripts can be edited through the insecure medium of the web, they are not allowed access to the Zope server's file-system. Normal Python builtins like 'open' are, therefore, not allowed. o Because many standard Python modules break the above two security restrictions, only a small subset of Python modules may be imported into a Python Scripts with the "import" statement unless they have been validated by Zope's security policy. Currently, the following standard python modules have been validated: o string o math o random o Products.PythonScripts.standard o Because it allows you to execute arbitrary python code, the python "exec" statement is not allowed in Python methods. o Because they may represent or cause security violations, some Python builtin functions are not allowed. The following Python builtins are not allowed: o open o input o raw_input o eval o execfile o compile o type o coerce o intern o dir o globals o locals o vars o buffer o reduce o Other builtins are restricted in nature. The following builtins are restricted: range -- Due to possible memory denial of service attacks, the range builtin is restricted to creating ranges less than 10,000 elements long. filter, map, tuple, list -- For the same reason, builtins that construct lists from sequences do not operate on strings. getattr, setattr, delattr -- Because these may enable Python code to circumvent Zope's security system, they are replaced with custom, security constrained versions. o In order to be consistent with the Python expressions available to DTML, the builtin functions are augmented with a small number of functions and a class: o test o namespace o render o same_type o DateTime o Because the "print" statement cannot operate normally in Zope, its effect has been changed. Rather than sending text to stdout, "print" appends to an internal variable. The special builtin name "printed" evaluates to the concatenation of all text printed so far during the current execution of the script.

In order to use the example code, create a directory called "MyScriptModules", or something equally descriptive, in your Zope's "Products" directory. Copy this file to a file called "__init__.py" in the new directory. Edit the new file, uncommenting the block of code for each module that you want to make available for import by Scripts. You can, of course, add your own code to your "__init__.py" for modules that are not listed below. The list is not comprehensive, but is provided as a decent cross-section of modules. NB: Placing security assestions within the package/module you are trying to import will not work unless that package/module is located in your Products directory. This is because that package/module would have to be imported for its included security assertions to take effect, but to do that would require importing a module without any security declarations, which defeats the point of the restricted python environment. Products work differently as they are imported at Zope startup. By placing a package/module in your Products directory, you are asserting, among other things, that it is safe for Zope to check that package/module for security assertions. As a result, please be careful when place packages or modules that are not Zope Products in the Products directory.

Home-page: http://pypi.python.org/pypi/zope.browserresource/ Author: Zope Corporation and Contributors Author-email: zope-dev@zope.org License: UNKNOWN Description: ======== Overview ======== *This package is at present not reusable without depending on a large chunk of the Zope Toolkit and its assumptions. It is maintained by the* `Zope Toolkit project `_. This package provides an implementation of browser resources. It also provides directives for defining those resources using ZCML. Resources are static files and directories that are served to the browser directly from the filesystem. The most common example are images, CSS style sheets, or JavaScript files. Resources are be registered under a symbolic name and can later be referred to by that name, so their usage is independent from their physical location. You can register a single file with the `` directive, and a whole directory with the `` directive, for example This causes a named adapter to be registered that adapts the request to zope.interface.Interface (XXX why do we not use an explicit interface?), so to later retrieve a resource, use `zope.component.getAdapter(request, name='myfile')`. There are two ways to traverse to a resource, 1. with the 'empty' view on a site, e. g. `http://localhost/@@/myfile` (This is declared by zope.browserresource) 2. with the `++resource++` namespace, e. g. `http://localhost/++resource++myfile` (This is declared by zope.traversing.namespace) In case of resource-directories traversal simply continues through its contents, e. g. `http://localhost/@@/main-images/subdir/sample.jpg` Rather than putting together the URL to a resource manually, you should use zope.traversing.browser.interfaces.IAbsoluteURL to get the URL, or for a shorthand, call the resource object. This has an additional benefit: If you want to serve resources from a different URL, for example because you want to use a web server specialized in serving static files instead of the appserver, you can register an IAbsoluteURL adapter for the site under the name 'resource' that will be used to compute the base URLs for resources. For example, if you register 'http://static.example.com/' as the base 'resource' URL, the resources from the above example would yield the following absolute URLs: http://static.example.com/@@/myfile and http://static.example.com/@@/main-images ======= CHANGES ======= 3.10.3 (2010-04-30) =================== - Prefer the standard libraries doctest module to the one from zope.testing. 3.10.2 (2009-11-25) =================== - The previous release had a broken egg, sorry. 3.10.1 (2009-11-24) =================== - Import hooks functionality from zope.component after it was moved there from zope.site. This lifts the dependency on zope.site and thereby, ZODB. - Import ISite and IPossibleSite from zope.component after they were moved there from zope.location. 3.10.0 (2009-09-25) =================== - Add an ability to forbid publishing of some files in the resource directory, this is done by fnmatch'ing the wildcards in the ``forbidden_names``class attribute of ``DirectoryResource``. By default, the ``.svn`` is in that attribute, so directories won't publish subversion system directory that can contain private information. 3.9.0 (2009-08-27) ================== Initial release. This package was splitted off zope.app.publisher as a part of refactoring process. Additional changes that are made during refactoring: * Resource class for file resources are now selected the pluggable way. The resource directory publisher and browser:resource ZCML directive now creating file resources using factory utility lookup based on the file extension, so it's now possible to add new resource types without introducing new ZCML directives and they will work inside resource directories as well. NOTE: the "resource_factories" attribute from the DirectoryResource was removed, so if you were using this attribute for changing resource classes for some file extensions, you need to migrate your code to new utility-based mechanism. See zope.browserresource.interfaces.IResourceFactoryFactory interface. * The Image resource class was removed, as they are actually simple files. To migrate, simply rename the "image" argument in browser:resource and browser:i18n-resource directives to "file", if you don't do this, resouces will work, but you'll get deprecation warnings. If you need custom behaviour for images, you can register a resource factory utility for needed file extensions. * The PageTemplateResource was moved into a separate package, "zope.ptresource", which is a plugin for this package now. Because of that, the "template" argument of browser:resource directive was deprecated and you should rename it to "file" to migrate. The PageTemplateResource will be created for "pt", "zpt" and "html" files automatically, if zope.ptresource package is included in your configuration. * Fix stripping the "I" from an interface name for icon title, if no title is specified. * When publishing a resource via Resources view, set resource parent to an ISite object, not to current site manager. * Clean up code and improve test coverage.

This package was splitted off zope.app.publisher as a part of refactoring process. Additional changes that are made during refactoring: * Resource class for file resources are now selected the pluggable way. The resource directory publisher and browser:resource ZCML directive now creating file resources using factory utility lookup based on the file extension, so it's now possible to add new resource types without introducing new ZCML directives and they will work inside resource directories as well. NOTE: the "resource_factories" attribute from the DirectoryResource was removed, so if you were using this attribute for changing resource classes for some file extensions, you need to migrate your code to new utility-based mechanism. See zope.browserresource.interfaces.IResourceFactoryFactory interface. * The Image resource class was removed, as they are actually simple files. To migrate, simply rename the "image" argument in browser:resource and browser:i18n-resource directives to "file", if you don't do this, resouces will work, but you'll get deprecation warnings. If you need custom behaviour for images, you can register a resource factory utility for needed file extensions. * The PageTemplateResource was moved into a separate package, "zope.ptresource", which is a plugin for this package now. Because of that, the "template" argument of browser:resource directive was deprecated and you should rename it to "file" to migrate. The PageTemplateResource will be created for "pt", "zpt" and "html" files automatically, if zope.ptresource package is included in your configuration. * Fix stripping the "I" from an interface name for icon title, if no title is specified. * When publishing a resource via Resources view, set resource parent to an ISite object, not to current site manager. * Clean up code and improve test coverage. zope2.13-2.13.21/source/zope.browserresource/src/0000755000175000017500000000000012214017540020431 5ustar arnauarnauzope2.13-2.13.21/source/zope.browserresource/src/zope.browserresource.egg-info/0000755000175000017500000000000012214017540026332 5ustar arnauarnauzope2.13-2.13.21/source/zope.browserresource/src/zope.browserresource.egg-info/PKG-INFO0000644000175000017500000001565612214017540027444 0ustar arnauarnauMetadata-Version: 1.0 Name: zope.browserresource Version: 3.10.3 Summary: Browser resources implementation for Zope. Home-page: http://pypi.python.org/pypi/zope.browserresource/ Author: Zope Corporation and Contributors Author-email: zope-dev@zope.org License: UNKNOWN Description: ======== Overview ======== *This package is at present not reusable without depending on a large chunk of the Zope Toolkit and its assumptions. It is maintained by the* `Zope Toolkit project `_. This package provides an implementation of browser resources. It also provides directives for defining those resources using ZCML. Resources are static files and directories that are served to the browser directly from the filesystem. The most common example are images, CSS style sheets, or JavaScript files. Resources are be registered under a symbolic name and can later be referred to by that name, so their usage is independent from their physical location. You can register a single file with the `` directive, and a whole directory with the `` directive, for example This causes a named adapter to be registered that adapts the request to zope.interface.Interface (XXX why do we not use an explicit interface?), so to later retrieve a resource, use `zope.component.getAdapter(request, name='myfile')`. There are two ways to traverse to a resource, 1. with the 'empty' view on a site, e. g. `http://localhost/@@/myfile` (This is declared by zope.browserresource) 2. with the `++resource++` namespace, e. g. `http://localhost/++resource++myfile` (This is declared by zope.traversing.namespace) In case of resource-directories traversal simply continues through its contents, e. g. `http://localhost/@@/main-images/subdir/sample.jpg` Rather than putting together the URL to a resource manually, you should use zope.traversing.browser.interfaces.IAbsoluteURL to get the URL, or for a shorthand, call the resource object. This has an additional benefit: If you want to serve resources from a different URL, for example because you want to use a web server specialized in serving static files instead of the appserver, you can register an IAbsoluteURL adapter for the site under the name 'resource' that will be used to compute the base URLs for resources. For example, if you register 'http://static.example.com/' as the base 'resource' URL, the resources from the above example would yield the following absolute URLs: http://static.example.com/@@/myfile and http://static.example.com/@@/main-images ======= CHANGES ======= 3.10.3 (2010-04-30) =================== - Prefer the standard libraries doctest module to the one from zope.testing. 3.10.2 (2009-11-25) =================== - The previous release had a broken egg, sorry. 3.10.1 (2009-11-24) =================== - Import hooks functionality from zope.component after it was moved there from zope.site.

Home-page: http://pypi.python.org/pypi/RestrictedPython Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: .. contents:: Overview ======== RestrictedPython provides a ``restricted_compile`` function that works like the built-in ``compile`` function, except that it allows the controlled and restricted execution of code: >>> src = ''' ... def hello_world(): ... return "Hello World!" ... ''' >>> from RestrictedPython import compile_restricted >>> code = compile_restricted(src, '', 'exec') The resulting code can be executed using the ``exec`` built-in: >>> exec(code) As a result, the ``hello_world`` function is now available in the global namespace: >>> hello_world() 'Hello World!' Compatibility ============= This release of RestrictedPython is compatible with Python 2.3, 2.4, 2.5, 2.6, and 2.7. Implementing a policy ===================== RestrictedPython only provides the raw material for restricted execution. To actually enforce any restrictions, you need to supply a policy implementation by providing restricted versions of ``print``, ``getattr``, ``setattr``, ``import``, etc. These restricted implementations are hooked up by providing a set of specially named objects in the global dict that you use for execution of code. Specifically: 1. ``_print_`` is a callable object that returns a handler for print statements. This handler must have a ``write()`` method that accepts a single string argument, and must return a string when called. ``RestrictedPython.PrintCollector.PrintCollector`` is a suitable implementation. 2. ``_write_`` is a guard function taking a single argument. If the object passed to it may be written to, it should be returned, otherwise the guard function should raise an exception. ``_write`` is typically called on an object before a ``setattr`` operation. 3. ``_getattr_`` and ``_getitem_`` are guard functions, each of which takes two arguments. The first is the base object to be accessed, while the second is the attribute name or item index that will be read. The guard function should return the attribute or subitem, or raise an exception. 4. ``__import__`` is the normal Python import hook, and should be used to control access to Python packages and modules. 5. ``__builtins__`` is the normal Python builtins dictionary, which should be weeded down to a set that cannot be used to get around your restrictions. A usable "safe" set is ``RestrictedPython.Guards.safe_builtins``. To help illustrate how this works under the covers, here's an example function:: def f(x): x.foo = x.foo + x[0] print x return printed and (sort of) how it looks after restricted compilation:: def f(x): # Make local variables from globals. _print = _print_() _write = _write_ _getattr = _getattr_ _getitem = _getitem_ # Translation of f(x) above _write(x).foo = _getattr(x, 'foo') + _getitem(x, 0) print >>_print, x return _print() Examples ======== ``print`` --------- To support the ``print`` statement in restricted code, we supply a ``_print_`` object (note that it's a *factory*, e.g. a class or a callable, from which the restricted machinery will create the object): >>> from RestrictedPython.PrintCollector import PrintCollector >>> _print_ = PrintCollector >>> src = ''' ... print "Hello World!" ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) As you can see, the text doesn't appear on stdout. The print collector collects it. We can have access to the text using the ``printed`` variable, though: >>> src = ''' ... print "Hello World!" ... result = printed ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) >>> result 'Hello World!\n' Built-ins --------- By supplying a different ``__builtins__`` dictionary, we can rule out unsafe operations, such as opening files: >>> from RestrictedPython.Guards import safe_builtins >>> restricted_globals = dict(__builtins__ = safe_builtins) >>> src = ''' ... open('/etc/passwd') ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) in restricted_globals Traceback (most recent call last): ... NameError: name 'open' is not defined Guards ------ Here's an example of a write guard that never lets restricted code modify (assign, delete an attribute or item) except dictionaries and lists: >>> from RestrictedPython.Guards import full_write_guard >>> _write_ = full_write_guard >>> _getattr_ = getattr >>> class BikeShed(object): ... colour = 'green' ... >>> shed = BikeShed() Normally accessing attriutes works as expected, because we're using the standard ``getattr`` function for the ``_getattr_`` guard: >>> src = ''' ... print shed.colour ... result = printed ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) >>> result 'green\n' However, changing an attribute doesn't work: >>> src = ''' ... shed.colour = 'red' ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) Traceback (most recent call last): ... TypeError: attribute-less object (assign or del) As said, this particular write guard (``full_write_guard``) will allow restricted code to modify lists and dictionaries: >>> fibonacci = [1, 1, 2, 3, 4] >>> transl = dict(one=1, two=2, tres=3) >>> src = ''' ... # correct mistake in list ... fibonacci[-1] = 5 ... # one item doesn't belong ... del transl['tres'] ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) >>> fibonacci [1, 1, 2, 3, 5] >>> sorted(transl.keys()) ['one', 'two'] Changes ======= 3.6.0 (2010-07-09) ------------------ - Added name check for names assigned during imports using the "from x import y" format. - Added test for name check when assigning an alias using multiple-context with statements in Python 2.7. - Added tests for protection of the iterators for dict and set comprehensions in Python 2.7. 3.6.0a1 (2010-06-05) -------------------- - Removed support for DocumentTemplate.sequence - this is handled in the DocumentTemplate package itself. 3.5.2 (2010-04-30) ------------------ - Removed a testing dependency on zope.testing. 3.5.1 (2009-03-17) ------------------ - Added tests for ``Utilities`` module. - Filtered DeprecationWarnings when importing Python's ``sets`` module. 3.5.0 (2009-02-09) ------------------ - Dropped legacy support for Python 2.1 / 2.2 (``__future__`` imports of ``nested_scopes`` / ``generators``.). 3.4.3 (2008-10-26) ------------------ - Fixed deprecation warning: ``with`` is now a reserved keyword on Python 2.6. That means RestrictedPython should run on Python 2.6 now.

Home-page: http://pypi.python.org/pypi/RestrictedPython Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: .. contents:: Overview ======== RestrictedPython provides a ``restricted_compile`` function that works like the built-in ``compile`` function, except that it allows the controlled and restricted execution of code: >>> src = ''' ... def hello_world(): ... return "Hello World!" ... ''' >>> from RestrictedPython import compile_restricted >>> code = compile_restricted(src, '', 'exec') The resulting code can be executed using the ``exec`` built-in: >>> exec(code) As a result, the ``hello_world`` function is now available in the global namespace: >>> hello_world() 'Hello World!' Compatibility ============= This release of RestrictedPython is compatible with Python 2.3, 2.4, 2.5, 2.6, and 2.7. Implementing a policy ===================== RestrictedPython only provides the raw material for restricted execution. To actually enforce any restrictions, you need to supply a policy implementation by providing restricted versions of ``print``, ``getattr``, ``setattr``, ``import``, etc. These restricted implementations are hooked up by providing a set of specially named objects in the global dict that you use for execution of code. Specifically: 1. ``_print_`` is a callable object that returns a handler for print statements. This handler must have a ``write()`` method that accepts a single string argument, and must return a string when called. ``RestrictedPython.PrintCollector.PrintCollector`` is a suitable implementation. 2. ``_write_`` is a guard function taking a single argument. If the object passed to it may be written to, it should be returned, otherwise the guard function should raise an exception. ``_write`` is typically called on an object before a ``setattr`` operation. 3. ``_getattr_`` and ``_getitem_`` are guard functions, each of which takes two arguments. The first is the base object to be accessed, while the second is the attribute name or item index that will be read. The guard function should return the attribute or subitem, or raise an exception. 4. ``__import__`` is the normal Python import hook, and should be used to control access to Python packages and modules. 5. ``__builtins__`` is the normal Python builtins dictionary, which should be weeded down to a set that cannot be used to get around your restrictions. A usable "safe" set is ``RestrictedPython.Guards.safe_builtins``. To help illustrate how this works under the covers, here's an example function:: def f(x): x.foo = x.foo + x[0] print x return printed and (sort of) how it looks after restricted compilation:: def f(x): # Make local variables from globals. _print = _print_() _write = _write_ _getattr = _getattr_ _getitem = _getitem_ # Translation of f(x) above _write(x).foo = _getattr(x, 'foo') + _getitem(x, 0) print >>_print, x return _print() Examples ======== ``print`` --------- To support the ``print`` statement in restricted code, we supply a ``_print_`` object (note that it's a *factory*, e.g. a class or a callable, from which the restricted machinery will create the object): >>> from RestrictedPython.PrintCollector import PrintCollector >>> _print_ = PrintCollector >>> src = ''' ... print "Hello World!" ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) As you can see, the text doesn't appear on stdout. The print collector collects it. We can have access to the text using the ``printed`` variable, though: >>> src = ''' ... print "Hello World!" ... result = printed ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) >>> result 'Hello World!\n' Built-ins --------- By supplying a different ``__builtins__`` dictionary, we can rule out unsafe operations, such as opening files: >>> from RestrictedPython.Guards import safe_builtins >>> restricted_globals = dict(__builtins__ = safe_builtins) >>> src = ''' ... open('/etc/passwd') ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) in restricted_globals Traceback (most recent call last): ... NameError: name 'open' is not defined Guards ------ Here's an example of a write guard that never lets restricted code modify (assign, delete an attribute or item) except dictionaries and lists: >>> from RestrictedPython.Guards import full_write_guard >>> _write_ = full_write_guard >>> _getattr_ = getattr >>> class BikeShed(object): ... colour = 'green' ... >>> shed = BikeShed() Normally accessing attriutes works as expected, because we're using the standard ``getattr`` function for the ``_getattr_`` guard: >>> src = ''' ... print shed.colour ... result = printed ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) >>> result 'green\n' However, changing an attribute doesn't work: >>> src = ''' ... shed.colour = 'red' ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) Traceback (most recent call last): ... TypeError: attribute-less object (assign or del) As said, this particular write guard (``full_write_guard``) will allow restricted code to modify lists and dictionaries: >>> fibonacci = [1, 1, 2, 3, 4] >>> transl = dict(one=1, two=2, tres=3) >>> src = ''' ... # correct mistake in list ... fibonacci[-1] = 5 ... # one item doesn't belong ... del transl['tres'] ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) >>> fibonacci [1, 1, 2, 3, 5] >>> sorted(transl.keys()) ['one', 'two'] Changes ======= 3.6.0 (2010-07-09) ------------------ - Added name check for names assigned during imports using the "from x import y" format. - Added test for name check when assigning an alias using multiple-context with statements in Python 2.7. - Added tests for protection of the iterators for dict and set comprehensions in Python 2.7. 3.6.0a1 (2010-06-05) -------------------- - Removed support for DocumentTemplate.sequence - this is handled in the DocumentTemplate package itself. 3.5.2 (2010-04-30) ------------------ - Removed a testing dependency on zope.testing. 3.5.1 (2009-03-17) ------------------ - Added tests for ``Utilities`` module. - Filtered DeprecationWarnings when importing Python's ``sets`` module. 3.5.0 (2009-02-09) ------------------ - Dropped legacy support for Python 2.1 / 2.2 (``__future__`` imports of ``nested_scopes`` / ``generators``.). 3.4.3 (2008-10-26) ------------------ - Fixed deprecation warning: ``with`` is now a reserved keyword on Python 2.6.

''' >>> from RestrictedPython import compile_restricted >>> code = compile_restricted(src, '', 'exec') The resulting code can be executed using the ``exec`` built-in: >>> exec(code) As a result, the ``hello_world`` function is now available in the global namespace: >>> hello_world() 'Hello World!' Compatibility ============= This release of RestrictedPython is compatible with Python 2.3, 2.4, 2.5, 2.6, and 2.7. Implementing a policy ===================== RestrictedPython only provides the raw material for restricted execution. To actually enforce any restrictions, you need to supply a policy implementation by providing restricted versions of ``print``, ``getattr``, ``setattr``, ``import``, etc. These restricted implementations are hooked up by providing a set of specially named objects in the global dict that you use for execution of code. Specifically: 1. ``_print_`` is a callable object that returns a handler for print statements. This handler must have a ``write()`` method that accepts a single string argument, and must return a string when called. ``RestrictedPython.PrintCollector.PrintCollector`` is a suitable implementation. 2. ``_write_`` is a guard function taking a single argument. If the object passed to it may be written to, it should be returned, otherwise the guard function should raise an exception. ``_write`` is typically called on an object before a ``setattr`` operation. 3. ``_getattr_`` and ``_getitem_`` are guard functions, each of which takes two arguments. The first is the base object to be accessed, while the second is the attribute name or item index that will be read. The guard function should return the attribute or subitem, or raise an exception. 4. ``__import__`` is the normal Python import hook, and should be used to control access to Python packages and modules. 5. ``__builtins__`` is the normal Python builtins dictionary, which should be weeded down to a set that cannot be used to get around your restrictions. A usable "safe" set is ``RestrictedPython.Guards.safe_builtins``. To help illustrate how this works under the covers, here's an example function:: def f(x): x.foo = x.foo + x[0] print x return printed and (sort of) how it looks after restricted compilation:: def f(x): # Make local variables from globals. _print = _print_() _write = _write_ _getattr = _getattr_ _getitem = _getitem_ # Translation of f(x) above _write(x).foo = _getattr(x, 'foo') + _getitem(x, 0) print >>_print, x return _print() Examples ======== ``print`` --------- To support the ``print`` statement in restricted code, we supply a ``_print_`` object (note that it's a *factory*, e.g. a class or a callable, from which the restricted machinery will create the object): >>> from RestrictedPython.PrintCollector import PrintCollector >>> _print_ = PrintCollector >>> src = ''' ... print "Hello World!" ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) As you can see, the text doesn't appear on stdout. The print collector collects it. We can have access to the text using the ``printed`` variable, though: >>> src = ''' ... print "Hello World!" ... result = printed ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) >>> result 'Hello World!\n' Built-ins --------- By supplying a different ``__builtins__`` dictionary, we can rule out unsafe operations, such as opening files: >>> from RestrictedPython.Guards import safe_builtins >>> restricted_globals = dict(__builtins__ = safe_builtins) >>> src = ''' ... open('/etc/passwd') ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) in restricted_globals Traceback (most recent call last): ... NameError: name 'open' is not defined Guards ------ Here's an example of a write guard that never lets restricted code modify (assign, delete an attribute or item) except dictionaries and lists: >>> from RestrictedPython.Guards import full_write_guard >>> _write_ = full_write_guard >>> _getattr_ = getattr >>> class BikeShed(object): ... colour = 'green' ... >>> shed = BikeShed() Normally accessing attriutes works as expected, because we're using the standard ``getattr`` function for the ``_getattr_`` guard: >>> src = ''' ... print shed.colour ... result = printed ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) >>> result 'green\n' However, changing an attribute doesn't work: >>> src = ''' ... shed.colour = 'red' ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) Traceback (most recent call last): ... TypeError: attribute-less object (assign or del) As said, this particular write guard (``full_write_guard``) will allow restricted code to modify lists and dictionaries: >>> fibonacci = [1, 1, 2, 3, 4] >>> transl = dict(one=1, two=2, tres=3) >>> src = ''' ... # correct mistake in list ... fibonacci[-1] = 5 ... # one item doesn't belong ... del transl['tres'] ... ''' >>> code = compile_restricted(src, '', 'exec') >>> exec(code) >>> fibonacci [1, 1, 2, 3, 5] >>> sorted(transl.keys()) ['one', 'two'] zope2.13-2.13.21/source/RestrictedPython/src/RestrictedPython/RestrictionMutator.py0000644000175000017500000003566312214017460027317 0ustar arnauarnau############################################################################## # # Copyright (c) 2002 Zope Foundation and Contributors. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

These notes will hopefully make this a little easier. :) - The important module is RCompile. The entry points are the compile_restricted_* functions. + compile_restricted_function is used by Python scripts. + compile_restricted_eval is used by ZPT and by DTML indirectly through Eval.RestrictionCapableEval. - OK, so lets see how this works by following the logic of compile_restricted_eval. - First, we create an RExpression, passing the source and a "file name", to be used in tracebacks. Now, an RExpression is just: + a subclass of RestrictedCompileMode and Expression. Expression is a subclass of AbstractCompileMode that sets it's mode to 'eval' and everided compile. Sigh. + RestrictedCompileMode is a subclass of AbstractCompileMode that changes a bunch of things. :) These include compile, so we can ignore the compile we got from Expression. It would have been simpler to just set the dang mode in RExpression. Sigh. RestrictedCompileMode seem to be the interestng base class. I assume it implements the interesting functionality. We'll see below... - Next, we call compileAndTuplize. + This calls compile on the RExpression. It has an error handler that does something that I hope I don't care about. :) + It then calls the genCode method on the RExpression. This is boring, so we'll not worry about it. - The compile method provided by RestrictedCompileMode is interesting. + First it calls _get_tree. * It uses compiler.parse to parse the source * it uses MutatingWalker.walk to mutate the tree using the RestrictedCompileMode's 'rm' attr, which is a RestrictionMutator. The RestrictionMutator has the recipies for mutating the parse tree. (Note, for comparison, that Zope3's zope.security.untrustedpython.rcompile module an alternative RestrictionMutator that provides a much smaller set of changes.) A mutator has visit method for different kinds of AST nodes. These visit methods may mutate nodes or return new nodes that replace the originally visited nodes. There is a default visitor that visits a node's children and replaces the children whose visitors returned new nodes. The walk function just calls the visitor for the root node of the given tree. Note _get_tree ignores the walk return value, thus assuming that the visitor for the root node doesn't return a new node. This is a theoretical bug that we can ignore. + Second, it generates the code. This too is boring. - So this seems simple enough. ;) When we want to add a check, we need to update or add a visit function in RestrictionMutator. How does a visit function work. - First, we usually call walker.defaultVisitNode(node). This transforms the node's child nodes. - Then we hack the node, or possibly return the node. To do this, we have to know how the node works. - The hack often involved changing the code to call some checker function. These have names like _name_. These are names that would be illegal in the input source. If this is a new function, we have to provide it in AccessControl.ZopeGuards._safe_globals. - Don't forget to add a test case to tests.before_and_after. zope2.13-2.13.21/source/RestrictedPython/src/RestrictedPython/Guards.py0000644000175000017500000001050712214017460024651 0ustar arnauarnau############################################################################## # # Copyright (c) 2002 Zope Foundation and Contributors. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

As a meta-class, ExtensionClass provides the following features: - Support for a class initialiser: >>> from ExtensionClass import ExtensionClass, Base >>> class C(Base): ... def __class_init__(self): ... print 'class init called' ... print self.__name__ ... def bar(self): ... return 'bar called' class init called C >>> c = C() >>> int(c.__class__ is C) 1 >>> int(c.__class__ is type(c)) 1 - Making sure that every instance of the meta-class has Base as a base class: >>> class X: ... __metaclass__ = ExtensionClass >>> Base in X.__mro__ 1 - Provide an inheritedAttribute method for looking up attributes in base classes: >>> class C2(C): ... def bar(*a): ... return C2.inheritedAttribute('bar')(*a), 42 class init called C2 >>> o = C2() >>> o.bar() ('bar called', 42) This is for compatability with old code. New code should use super instead. The base class, Base, exists mainly to support the __of__ protocol. The __of__ protocol is similar to __get__ except that __of__ is called when an implementor is retrieved from an instance as well as from a class: >>> class O(Base): ... def __of__(*a): ... return a >>> o1 = O() >>> o2 = O() >>> C.o1 = o1 >>> c.o2 = o2 >>> c.o1 == (o1, c) 1 >>> C.o1 == o1 1 >>> int(c.o2 == (o2, c)) 1 We accomplish this by making a class that implements __of__ a descriptor and treating all descriptor ExtensionClasses this way. That is, if an extension class is a descriptor, it's __get__ method will be called even when it is retrieved from an instance. >>> class O(Base): ... def __get__(*a): ... return a ... >>> o1 = O() >>> o2 = O() >>> C.o1 = o1 >>> c.o2 = o2 >>> int(c.o1 == (o1, c, type(c))) 1 >>> int(C.o1 == (o1, None, type(c))) 1 >>> int(c.o2 == (o2, c, type(c))) 1 $Id: __init__.py 40218 2005-11-18 14:39:19Z andreasjung $ """ from _ExtensionClass import * zope2.13-2.13.21/source/Record/include/ExtensionClass/tests.py0000644000175000017500000004744512214017456022776 0ustar arnauarnau############################################################################## # # Copyright (c) 2003 Zope Corporation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

The basic idea is: I'll call this the "encapsulated base" scheme. Consider: >>> class X(Base): ... pass >>> class Y(Base): ... pass >>> class Z(Base): ... pass >>> class C(X, Y, Z): ... def foo(self): ... return 42 When we look up an attribute, we do the following: - Look in C's dictionary first. - Look up the attribute in X. We don't care how we get the attribute from X. If X is a new-style-class, we use the new algorithm. If X is a classic class, we use left-to-right depth-first. If X is an nsEC, use the "encapsulated base" algorithm. If we don't find the attribute in X, look in Y and then in Z, using the same approach. This algorithm will produce backward compatible results, providing the equivalent of left-to-right depth-first for nsECs and classic classes. We'll actually do something less abstract. We'll use a simple algorthm to merge the __mro__ of the base classes, computing an __mro__ for classic classes using the left-to-right depth-first algorithm. We'll basically lay the mros end-to-end left-to-right and remove repeats, keeping the first occurence of each class. >>> [c.__name__ for c in C.__mro__] ['C', 'X', 'Y', 'Z', 'Base', 'object'] For backward-compatability's sake, we actually depart from the above description a bit. We always put Base and object last in the mro, as shown in the example above. The primary reason for this is that object provides a do-nothing __init__ method. It is common practice to mix a C-implemented base class that implements a few methods with a Python class that implements those methods and others. The idea is that the C implementation overrides selected methods in C, so the C subclass is listed first. Unfortunately, because all extension classes are required to subclass Base, and thus, object, the C subclass brings along the __init__ object from objects, which would hide any __init__ method provided by the Python mix-in. Base and object are special in that they are implied by their meta classes. For example, a new-style class always has object as an ancestor, even if it isn't listed as a base: >>> class O: ... __metaclass__ = type >>> [c.__name__ for c in O.__bases__] ['object'] >>> [c.__name__ for c in O.__mro__] ['O', 'object'] Similarly, Base is always an ancestor of an extension class: >>> class E: ... __metaclass__ = ExtensionClass >>> [c.__name__ for c in E.__bases__] ['Base'] >>> [c.__name__ for c in E.__mro__] ['E', 'Base', 'object'] Base and object are generally added soley to get a particular meta class. They aren't used to provide application functionality and really shouldn't be considered when reasoning about where attributes come from. They do provide some useful default functionality and should be included at the end of the mro. Here are more examples: >>> from ExtensionClass import Base >>> class NA(object): ... pass >>> class NB(NA): ... pass >>> class NC(NA): ... pass >>> class ND(NB, NC): ... pass >>> [c.__name__ for c in ND.__mro__] ['ND', 'NB', 'NC', 'NA', 'object'] >>> class EA(Base): ... pass >>> class EB(EA): ... pass >>> class EC(EA): ... pass >>> class ED(EB, EC): ... pass >>> [c.__name__ for c in ED.__mro__] ['ED', 'EB', 'EA', 'EC', 'Base', 'object'] >>> class EE(ED, ND): ... pass >>> [c.__name__ for c in EE.__mro__] ['EE', 'ED', 'EB', 'EA', 'EC', 'ND', 'NB', 'NC', 'NA', 'Base', 'object'] >>> class EF(ND, ED): ... pass >>> [c.__name__ for c in EF.__mro__] ['EF', 'ND', 'NB', 'NC', 'NA', 'ED', 'EB', 'EA', 'EC', 'Base', 'object'] >>> class CA: ... pass >>> class CB(CA): ... pass >>> class CC(CA): ... pass >>> class CD(CB, CC): ... pass >>> class ECD(Base, CD): ... pass >>> [c.__name__ for c in ECD.__mro__] ['ECD', 'CD', 'CB', 'CA', 'CC', 'Base', 'object'] >>> class CDE(CD, Base): ... pass >>> [c.__name__ for c in CDE.__mro__] ['CDE', 'CD', 'CB', 'CA', 'CC', 'Base', 'object'] >>> class CEND(CD, ED, ND): ... pass >>> [c.__name__ for c in CEND.__mro__] ['CEND', 'CD', 'CB', 'CA', 'CC', """ \ """'ED', 'EB', 'EA', 'EC', 'ND', 'NB', 'NC', 'NA', 'Base', 'object'] """ def test_avoiding___init__decoy_w_inheritedAttribute(): """ >>> class Decoy(Base): ... pass >>> class B(Base): ... def __init__(self, a, b): ... print '__init__', a, b >>> class C(Decoy, B): ... def __init__(self): ... print 'C init' ...

This extra member is a method chain ('PyMethodChain') containing a linked list of method definition ('PyMethodDef') lists. Method chains can be used to implement method inheritance in C. Most extensions don't use method chains, but simply define method lists, which are null-terminated arrays of method definitions. A macro, 'METHOD_CHAIN' is defined in 'ExtensionClass.h' that converts a method list to a method chain. (See the example below.) - Module functions that create new instances must be replaced by an '__init__' method that initializes, but does not create storage for instances. - The extension class must be initialized and exported to the module with:: PyExtensionClass_Export(d,"name",type); where 'name' is the module name and 'type' is the extension class type object. Attribute lookup Attribute lookup is performed by calling the base extension class 'getattr' operation for the base extension class that includes C data, or for the first base extension class, if none of the base extension classes include C data. 'ExtensionClass.h' defines a macro 'Py_FindAttrString' that can be used to find an object's attributes that are stored in the object's instance dictionary or in the object's class or base classes:: v = Py_FindAttrString(self,name); In addition, a macro is provided that replaces 'Py_FindMethod' calls with logic to perform the same sort of lookup that is provided by 'Py_FindAttrString'. Linking The extension class mechanism was designed to be useful with dynamically linked extension modules. Modules that implement extension classes do not have to be linked against an extension class library. The macro 'PyExtensionClass_Export' imports the 'ExtensionClass' module and uses objects imported from this module to initialize an extension class with necessary behavior. */ #ifndef EXTENSIONCLASS_H #define EXTENSIONCLASS_H #include "Python.h" #include "import.h" /* Declarations for objects of type ExtensionClass */ #define EC PyTypeObject #define PyExtensionClass PyTypeObject #define EXTENSIONCLASS_BINDABLE_FLAG 1 << 2 #define EXTENSIONCLASS_NOINSTDICT_FLAG 1 << 5 typedef struct { PyObject_HEAD } _emptyobject; static struct ExtensionClassCAPIstruct { /***************************************************************************** WARNING: THIS STRUCT IS PRIVATE TO THE EXTENSION CLASS INTERFACE IMPLEMENTATION AND IS SUBJECT TO CHANGE !!! *****************************************************************************/ PyObject *(*EC_findiattrs_)(PyObject *self, char *cname); int (*PyExtensionClass_Export_)(PyObject *dict, char *name, PyTypeObject *typ); PyObject *(*PyECMethod_New_)(PyObject *callable, PyObject *inst); PyExtensionClass *ECBaseType_; PyExtensionClass *ECExtensionClassType_; } *PyExtensionClassCAPI = NULL; #define ECBaseType (PyExtensionClassCAPI->ECBaseType_) #define ECExtensionClassType (PyExtensionClassCAPI->ECExtensionClassType_) /* Following are macros that are needed or useful for defining extension classes: */ /* This macro redefines Py_FindMethod to do attribute for an attribute name given by a C string lookup using extension class meta-data.

    External Methods allow you to add functionality to Zope by writing Python functions which are exposed as callable Zope objects. The module name should give the name of the Python module without the ".py" file extension. The function name should name a callable object found in the module.

Home-page: http://pypi.python.org/pypi/Products.StandardCacheManagers Author: Zope Foundation and Contributors Author-email: zope-dev@zope.org License: ZPL 2.1 Description: Overview ======== This package provides two cache managers for Zope 2. A RAMCacheManager and an Accelerated HTTP cache manager, which adds HTTP cache headers to responses. The following is intended for people interested in the internals of RAMCacheManager, such as maintainers. Introduction ============ The caching framework does not interpret the data in any way, it acts just as a general storage for data passed to it. It tries to check if the data is pickleable though. IOW, only pickleable data is cacheable. The idea behind the RAMCacheManager is that it should be shared between threads, so that the same objects are not cached in each thread. This is achieved by storing the cache data structure itself as a module level variable (RAMCacheManager.caches). This, of course, requires locking on modifications of that data structure. Each RAMCacheManager instance has one cache in RAMCacheManager.caches dictionary. A unique __cacheid is generated when creating a cache manager and it's used as a key for caches. Object Hierarchy ================ RAMCacheManager RAMCache ObjectCacheEntries CacheEntry RAMCacheManager is a persistent placeful object. It is assigned a unique __cacheid on its creation. It is then used as a key to look up the corresponding RAMCache object in the global caches dictionary. So, each RAMCacheManager has a single RAMCache related to it. RAMCache is a volatile cache, unique for each RAMCacheManager. It is shared among threads and does all the locking. It has a writelock. No locking is done on reading though. RAMCache keeps a dictionary of ObjectCacheEntries indexed by the physical path of a cached object. ObjectCacheEntries is a container for cached values for a single object. The values in it are indexed by a tuple of a view_name, interesting request variables, and extra keywords passed to Cache.ZCache_set(). CacheEntry is a wrapper around a single cached value. It stores the data itself, creation time, view_name and keeps the access count. Changelog ========= 2.13.0 (2010-07-11) ------------------- - Released as separate package.

The following is intended for people interested in the internals of RAMCacheManager, such as maintainers. Introduction ============ The caching framework does not interpret the data in any way, it acts just as a general storage for data passed to it. It tries to check if the data is pickleable though. IOW, only pickleable data is cacheable. The idea behind the RAMCacheManager is that it should be shared between threads, so that the same objects are not cached in each thread. This is achieved by storing the cache data structure itself as a module level variable (RAMCacheManager.caches). This, of course, requires locking on modifications of that data structure. Each RAMCacheManager instance has one cache in RAMCacheManager.caches dictionary. A unique __cacheid is generated when creating a cache manager and it's used as a key for caches. Object Hierarchy ================ RAMCacheManager RAMCache ObjectCacheEntries CacheEntry RAMCacheManager is a persistent placeful object. It is assigned a unique __cacheid on its creation. It is then used as a key to look up the corresponding RAMCache object in the global caches dictionary. So, each RAMCacheManager has a single RAMCache related to it. RAMCache is a volatile cache, unique for each RAMCacheManager. It is shared among threads and does all the locking. It has a writelock. No locking is done on reading though. RAMCache keeps a dictionary of ObjectCacheEntries indexed by the physical path of a cached object. ObjectCacheEntries is a container for cached values for a single object. The values in it are indexed by a tuple of a view_name, interesting request variables, and extra keywords passed to Cache.ZCache_set(). CacheEntry is a wrapper around a single cached value. It stores the data itself, creation time, view_name and keeps the access count. zope2.13-2.13.21/source/Products.StandardCacheManagers/setup.cfg0000644000175000017500000000007312214017675023231 0ustar arnauarnau[egg_info] tag_build = tag_date = 0 tag_svn_revision = 0 zope2.13-2.13.21/source/Products.StandardCacheManagers/COPYRIGHT.txt0000644000175000017500000000004012214017675023513 0ustar arnauarnauZope Foundation and Contributorszope2.13-2.13.21/source/Products.StandardCacheManagers/buildout.cfg0000644000175000017500000000033512214017675023721 0ustar arnauarnau[buildout] develop = . parts = interpreter test [interpreter] recipe = zc.recipe.egg interpreter = python eggs = Products.StandardCacheManagers [test] recipe = zc.recipe.testrunner eggs = Products.StandardCacheManagers zope2.13-2.13.21/source/Products.StandardCacheManagers/bootstrap.py0000644000175000017500000000742012214017675024002 0ustar arnauarnau############################################################################## # # Copyright (c) 2006 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

It provides access statistics and simple configuration options. Not all objects are appropriate for use with a RAM Cache Manager. See the **caveats** section below. Storing the result in memory results in the fastest possible cache retrieval, but carries some risks. Unconstrained, it can consume too much RAM. And it doesn't reduce network traffic, it only helps Zope return a result more quickly. Fortunately, RAM cache managers have tunable parameters. You can configure the threshold on the number of entries that should be in the cache, which defaults to 1000. Reduce it if the cache is taking up too much memory or increase it if entries are being cleared too often. You can also configure the cleanup interval. If the RAM cache is fluctuating too much in memory usage, reduce the cleanup interval. Finally, you can configure the list of REQUEST variables that will be used in the cache key. This can be a simple and effective way to distinguish requests from authenticated versus anonymous users or those with session cookies. If you find that some of your objects need certain cache parameters while others need somewhat different parameters, create multiple RAM cache managers. The 'Statistics' tab allows you to view a summary of the contents of the cache. Click the column headers to re-sort the list, twice to sort backwards. You can use the statistics to gauge the benefit of caching each of your objects. For a given object, if the number of hits is less than or not much greater than the number of misses, you probably need to re-evaluate how that object is cached. Caveats You should generally not cache the following with RAM Cache Manager: * Images * Files * Complete web pages Although Zope does not prevent you from doing so, it generally does not make sense to associate any of these objects with a RAM cache manager. The cache will simply not cache image or file data, since the data is already available in RAM. In addition, be careful with complete web pages. The problem is that most cacheable objects will cache only their return value; important out-of-band information such as the HTTP response code is typically not cached. For example, if you cache a page which calls RESPONSE.redirect(), a client that gets a cache hit will see an HTTP 200 response code instead of the redirect. For all of the above objects, another kind of cache manager, an *accelerated HTTP cache manager*, is available and more suitable. ././@LongLink0000000000000000000000000000015100000000000011562 Lustar rootrootzope2.13-2.13.21/source/Products.StandardCacheManagers/src/Products/StandardCacheManagers/help/Accel.stxzope2.13-2.13.21/source/Products.StandardCacheManagers/src/Products/StandardCacheManagers/help/Accel0000644000175000017500000000613212214017675032030 0ustar arnauarnau Accelerated HTTP Cache Managers The HTTP protocol provides for headers that can indicate to downstream proxy caches, browser caches, and dedicated caches that certain documents and images are cacheable. Most images, for example, can safely be cached for a long time. Anonymous visits to most primary pages can be cached as well. An accelerated HTTP cache manager lets you control the headers that get sent with the responses to requests so that downstream caches will know what to cache and for how long. This allows you to reduce the traffic to your site and handle larger loads than otherwise possible. You can associate accelerated HTTP cache managers with any kind of cacheable object that can be viewed through the web. The main risk in using an accelerated HTTP cache manager involves a part of a page setting headers that apply to the whole response. If, for example, your home page contains three parts that are cacheable and one of those parts is associated with an accelerated HTTP cache manager, Zope will return the headers set by the part of the page, making downstream caches think that the whole page should be cached. The workaround is simple: don't use an accelerated HTTP cache manager with objects that make up parts of a page unless you really know what you're doing. There are some parameters available for accelerated HTTP cache managers. The interval is the number of seconds the downstream caches should cache the object. 3600 seconds, or one hour, is a good default. If you find that some objects need one interval and other objects should be set to another interval, use multiple cache managers. If you set the *cache anonymous connections only* checkbox, you will reduce the possibility of caching private data. The *notify URLs* parameter allows you to specify the URLs of specific downstream caches so they can receive invalidation messages as 'PURGE' directives. Dedicated HTTP cache software such as Squid will clear cached data for a given URL when receiving the 'PURGE' directive. (More details below.) Simple statistics are provided. Remember that the only time Zope receives a request that goes through an HTTP cache is when the HTTP cache had a *miss*. So the hits seen by Zope correspond to misses seen by the HTTP cache. To do traffic analysis, you should consult the downstream HTTP caches. When testing the accelerated HTTP cache manager, keep in mind that the *reload* button on most browsers causes the 'Pragma: no-cache' header to be sent, forcing HTTP caches to reload the page as well. Try using telnet, netcat, or tcpwatch to observe the headers. To allow Zope to execute the Squid PURGE directive, make sure the following lines or the equivalent are in squid.conf (changing 'localhost' to the correct host name if Squid is on a different machine):: acl PURGE method purge http_access allow localhost http_access allow purge localhost http_access deny purge http_access deny all zope2.13-2.13.21/source/Products.StandardCacheManagers/src/Products/StandardCacheManagers/tests/0000755000175000017500000000000012214017675031306 5ustar arnauarnau././@LongLink0000000000000000000000000000017500000000000011570 Lustar rootrootzope2.13-2.13.21/source/Products.StandardCacheManagers/src/Products/StandardCacheManagers/tests/test_CacheManagerLocation.pyzope2.13-2.13.21/source/Products.StandardCacheManagers/src/Products/StandardCacheManagers/tests/test0000644000175000017500000001141712214017675032214 0ustar arnauarnau############################################################################## # # Copyright (c) 2010 Zope Foundation and Contributors. # All Rights Reserved. # # This software is subject to the provisions of the Zope Public License, # Version 2.1 (ZPL).

    The RAM Cache Manager allows you to cache the result of calling expensive objects, such as Python Scripts and External Methods, in memory. Because it does not cache HTTP headers, caching full web pages is generally not advised.

WebDAV, as an extension to the HTTP Protocol, allows the users to create *Write Locks* as a way of trying to avoid the "lost updates problem". However, sometimes WriteLocks may become abandoned. This may be due to users forgetting to unlock their resources, software failures such as crashes, etc. In many cases, locks might just time out before this becomes a problem. In cases where it's not, this control panel object may be used to locate locked resources inside of Zope and clear *ALL* of their WebDAV writelocks. Controls 'Path' -- This lets you enter a path (based off the root of the Zope site) to filter down the list of locked objects. Clicking 'Go' executes the filter. When locked objects are found, they are listed one per line with a checkbox that can be used to select the item. Also listed in each line is information about the lock(s) on the object - the user who created the lock (identified by the path to the user folder the user is defined in), and the locktoken that identifies the lock. In the majority of cases, there should only be one lock per object. '[Checkbox]' -- Selects locked items. 'Select All' -- This button marks all items displayed as selected. 'Deselect All' -- After 'Select All' has been clicked, it changes to say 'Deselect All'. Clicking this deselects all displayed items. 'Unlock objects' -- Unlocks the selected items.zope2.13-2.13.21/source/Products.OFSP/src/Products/OFSP/help/dtml-comment.stx0000644000175000017500000000127612214017450025243 0ustar arnauarnaucomment: Comments DTML The comment tag lets you document your DTML with comments.

It can act as a template to display other objects. It can also hold small pieces of content which are inserted into other DTML Documents or DTML Methods. The DTML Method's id is available via the 'document_id' variable and the title is available via the 'document_title' variable. """ def __call__(client=None, REQUEST={}, **kw): """ Calling a DTMLMethod causes the Method to interpret the DTML code that it contains. The method returns the result of the interpretation, which can be any kind of object. To accomplish its task, DTML Method often needs to resolve various names into objects. For example, when the code '<dtml-var spam>' is executed, the DTML engine tries to resolve the name 'spam'. In order to resolve names, the Method must be passed a namespace to look them up in. This can be done several ways: * By passing a 'client' object -- If the argument 'client' is passed, then names are looked up as attributes on the argument. * By passing a 'REQUEST' mapping -- If the argument 'REQUEST' is passed, then names are looked up as items on the argument. If the object is not a mapping, an TypeError will be raised when a name lookup is attempted. * By passing keyword arguments -- names and their values can be passed as keyword arguments to the Method. The namespace given to a DTML Method is the composite of these three methods. You can pass any number of them or none at all. Names will be looked up first in the keyword argument, next in the client and finally in the mapping. Unlike DTMLDocuments, DTMLMethods do not look up names in their own instance dictionary. Passing in a namespace to a DTML Method is often referred to as providing the Method with a *context*. DTML Methods can be called three ways: From DTML A DTML Method can be called from another DTML Method or Document:: In this example, the Method 'aDTMLMethod' is being called from another DTML object by name. The calling method passes the value 'this' as the client argument and the current DTML namespace as the REQUEST argument. The above is identical to this following usage in a DTML Python expression:: From Python Products, External Methods, and Scripts can call a DTML Method in the same way as calling a DTML Method from a Python expression in DTML; as shown in the previous example. By the Publisher When the URL of a DTML Method is fetched from Zope, the DTML Method is called by the publisher. The REQUEST object is passed as the second argument to the Method.

The 'Cache' tab allows you to associate a cacheable object with a cache manager. It is only available when at least one cache manager exists somewhere in the current context. Use the drop-down box to select which cache manager should be associated with the object. Some types of objects provide additional caching options. DTML methods can be cached according to the DTML namespace. The entry box on the 'Cache' tab allows you to enter the names (one per line) that Zope should look up in the namespace to create the cache key. Note, however, that the namespace lookup operation can be expensive, so use this feature with care. Also note that it is not possible for accelerated HTTP cache managers to make use of this feature. (TODO) Python scripts may also provide further options. zope2.13-2.13.21/source/Products.OFSP/src/Products/OFSP/help/dtml-var.stx0000644000175000017500000001125012214017450024362 0ustar arnauarnauvar: Inserts a variable The 'var' tags allows you insert variables into DTML output. Syntax 'var' tag syntax:: The 'var' tag is a singleton tag. The 'var' tag finds a variable by searching the DTML namespace which usually consists of current object, the current object's containers, and finally the web request. If the variable is found, it is inserted into the DTML output. If not found, Zope raises an error. 'var' tag entity syntax:: &dtml-variableName; Entity syntax is a short cut which inserts and HTML quotes the variable. It is useful when inserting variables into HTML tags. 'var' tag entity syntax with attributes:: &dtml.attribute1[.attribute2]...-variableName; To a limited degree you may specify attributes with the entity syntax. You may include zero or more attributes delimited by periods. You cannot provide arguments for attributes using the entity syntax. If you provide zero or more attributes, then the variable is not automatically HTML quoted. Thus you can avoid HTML quoting with this syntax, '&dtml.-variableName;'. Attributes html_quote -- Convert characters that have special meaning in HTML to HTML character entities. missing=string -- Specify a default value in case Zope cannot find the variable. fmt=string -- Format a variable. Zope provides a few built-in formats including C-style format strings. For more information on C-style format strings see the "Python Library Reference":http://www.python.org/doc/current/lib/typesseq-strings.html If the format string is not a built-in format, then it is assumed to be a method of the object, and it called. whole-dollars -- Formats the variable as dollars. dollars-and-cents -- Formats the variable as dollars and cents. collection-length -- The length of the variable, assuming it is a sequence. structured-text -- Formats the variable as Structured Text. For more information on Structured Text see "Structured Text How-To":http://www.zope.org/Members/millejoh/structuredText on the Zope.org web site. null=string -- A default value to use if the variable is None. lower -- Converts upper-case letters to lower case. upper -- Converts lower-case letters to upper case. capitalize -- Capitalizes the first character of the inserted word. spacify -- Changes underscores in the inserted value to spaces. thousands_commas -- Inserts commas every three digits to the left of a decimal point in values containing numbers for example '12000' becomes '12,000'. url -- Inserts the URL of the object, by calling its 'absolute_url' method. url_quote -- Converts characters that have special meaning in URLs to HTML character entities. url_quote_plus -- URL quotes character, like 'url_quote' but also converts spaces to plus signs. url_unquote -- Converts HTML '%xx' escapes into their single character values (ie: undoes the effects of url_quote). url_unquote_plus -- Like url_unquote, but also replaces '+' characters with spaces (ie: undoes the effects of url_quote_plus). sql_quote -- Converts single quotes to pairs of single quotes. This is needed to safely include values in SQL strings. newline_to_br -- Convert newlines (including carriage returns) to HTML break tags. size=arg -- Truncates the variable at the given length (Note: if a space occurs in the second half of the truncated string, then the string is further truncated to the right-most space). etc=arg -- Specifies a string to add to the end of a string which has been truncated (by setting the 'size' attribute listed above). By default, this is '...' Examples Inserting a simple variable into a document:: Truncation:: will produce the following output if *colors* is the string 'red yellow green':: red yellow, etc. C-style string formatting:: renders to:: 23432.23 Inserting a variable, *link*, inside an HTML 'A' tag with the entity syntax:: Link Inserting a link to a document 'doc', using entity syntax with attributes:: This creates an HTML link to an object using its URL and title. This example calls the object's 'absolute_url' method for the URL (using the 'url' attribute) and its 'title_or_id' method for the title. zope2.13-2.13.21/source/Products.OFSP/src/Products/OFSP/help/dtml-return.stx0000644000175000017500000000112712214017450025113 0ustar arnauarnaureturn: Returns data The 'return' tag stops executing DTML and returns data.

The method returns the result of the interpretation, which can be any kind of object. To accomplish its task, DTML Document often needs to resolve various names into objects. For example, when the code '<dtml-var spam>' is executed, the DTML engine tries to resolve the name 'spam'. In order to resolve names, the Document must be passed a namespace to look them up in. This can be done several ways: * By passing a 'client' object -- If the argument 'client' is passed, then names are looked up as attributes on the argument. * By passing a 'REQUEST' mapping -- If the argument 'REQUEST' is passed, then names are looked up as items on the argument. If the object is not a mapping, an TypeError will be raised when a name lookup is attempted. * By passing keyword arguments -- names and their values can be passed as keyword arguments to the Document. The namespace given to a DTML Document is the composite of these three methods. You can pass any number of them or none at all. Names are looked up first in the keyword arguments, then in the client, and finally in the mapping. A DTMLDocument implicitly pass itself as a client argument in addition to the specified client, so names are looked up in the DTMLDocument itself. Passing in a namespace to a DTML Document is often referred to as providing the Document with a *context*. DTML Documents can be called three ways. From DTML A DTML Document can be called from another DTML Method or Document:: In this example, the Document 'aDTMLDocument' is being called from another DTML object by name. The calling method passes the value 'this' as the client argument and the current DTML namespace as the REQUEST argument.

One way to deal with expensive tasks is to cache them. The first time the computation is requested, the results are stored in a table or *cache*. Subsequent requests get the results from the cache. This can result in a dramatic speed increase. There are so many possible strategies for caching that no one could possibly come up with them all. Caches can be stored in memory, on disk, on other computers, or by other means. Caches can be limited in size or unconstrained. They can be made to work with only specific types of objects. They can be tuned in different ways. So instead of trying to provide for every possible caching strategy, Zope defines an API called *cache management* that lets developers write their own caching strategies, or *cache managers*, and lets site administrators easily connect cacheable objects to those cache managers. You can use caching to speed up access to often-requested pages, reduce disk access and network traffic, and deal with heavy loads. All these benefits come with risks of excessive caching, however, so it's important to fine-tune the cache settings. More on this later. How to set up caching The first thing you need to do is create a cache manager instance. In the Zope management interface, go to a folder containing objects that would benefit from caching. From the add list, select a cache manager type such as 'RAM Cache Manager'. Use an ID that describes the purpose of the cache manager. Next, visit one of the objects that you want to cache. A new tab labeled 'Cache' should be visible. Select it. From the drop-down box, select the cache manager you just created and press the 'Change' button. The object is now ready to be cached. Visit the 'View' tab. If the object is a script that takes a long time to render, the first view will still take just as long as before. But if you're using a RAM cache manager or similar, the second view should be much faster. Press the *reload* button in your browser to try it out. You can associate many objects to a cache manager at once using the 'Associate' tab of all cache managers. Visit the cache manager object you created and select the 'Associate' tab. Press the 'Locate' button. Zope will locate all cacheable objects in the folder. Select the checkboxes next to the objects you want to cache and press the 'Save changes' button. Inherent risks Cache managers generally don't know the nature of what is being cached, so here are some issues that can surface: - Data that is intended for authorized viewers only can be inadvertently cached in public caches. - Data is cached for too long a time. - If more than one cache is involved, data is purged from one cache but not the other. - A method that makes up part of the page sets the caching headers for the entire response, fooling downstream caches into thinking the whole response should be cached. - Result data can depend on any number of objects. Early on it was decided that the standard cache managers will not try to deduce dependencies, but instead rely on the user for configuration of simple dependencies. Because of these risks, you should be careful when setting up caching. You'll need to fine-tune the cache settings. Sometimes you'll find that you can't cache one of your major pages, but that you can cache pieces of it. Also remember that caching can actually slow down Zope if it is applied unscrupulously. You should perform speed tests to verify that caching really does speed up your site. zope2.13-2.13.21/source/Products.OFSP/src/Products/OFSP/help/DTML-Method.stx0000644000175000017500000000061512214017450024615 0ustar arnauarnauDTML Method: Template object.

Click on a historical version to view the object as it existed at a given point in history. '[Checkbox]' -- Select a historical revision. 'Copy to present' -- Changes the object to the same state as the selected historical revision. 'Compare' -- Summarizes the difference between two historical revisions. If you select one historical revision it will be compared to the current state. The comparison shows the changes needed to change the older revision to match the newer revision. zope2.13-2.13.21/source/Products.OFSP/src/Products/OFSP/help/dtml-tree.stx0000644000175000017500000001016112214017450024531 0ustar arnauarnautree: Inserts a tree widget The 'tree' tag displays a dynamic tree widget by querying Zope objects. Syntax 'tree' tag syntax:: The 'tree' tag is a block tag. It renders a dynamic tree widget in HTML. The root of the tree is given by variable name or expression, if present, otherwise it defaults to the current object. The 'tree' block is rendered for each tree node, with the current node pushed onto the DTML namespace. Tree state is set in HTTP cookies. Thus for trees to work, cookies must be enabled. Also you can only have one tree per page. Attributes branches=string -- Finds tree branches by calling the named method. The default method is 'tpValues' which most Zope objects support. branches_expr=string -- Finds tree branches by evaluating the expression. id=string -- The name of a method or id to determine tree state. It defaults to 'tpId' which most Zope objects support. This attribute is for advanced usage only. url=string -- The name of a method or attribute to determine tree item URLs. It defaults to 'tpURL' which most Zope objects support. This attribute is for advanced usage only. leaves=string -- The name of a DTML Document or Method used to render nodes that don't have any children. Note: this document should begin with '' and end with '' in order to ensure proper display in the tree. header=string -- The name of a DTML Document or Method displayed before expanded nodes. If the header is not found, it is skipped. footer=string -- The name of a DTML Document or Method displayed after expanded nodes. If the footer is not found, it is skipped. nowrap=boolean -- If true then rather than wrap, nodes may be truncated to fit available space. sort=string -- Sorts the branches by the named attribute. reverse -- Reverses the order of the branches. assume_children=boolean -- Assumes that nodes have children. This is useful if fetching and querying child nodes is a costly process. This results in plus boxes being drawn next to all nodes. single=boolean -- Allows only one branch to be expanded at a time. When you expand a new branch, any other expanded branches close. skip_unauthorized -- Skips nodes that the user is unauthorized to see, rather than raising an error. urlparam=string -- A query string which is included in the expanding and contracting widget links. This attribute is for advanced usage only. prefix=string -- Provide versions of the tag variables that start with this prefix instead of "tree", and that use underscores (_) instead of hyphens (-). The prefix must start with a letter and contain only alphanumeric characters and underscores (_). Tag Variables tree-item-expanded -- True if the current node is expanded. tree-item-url -- The URL of the current node. tree-root-url -- The URL of the root node. tree-level -- The depth of the current node. Top-level nodes have a depth of zero. tree-colspan -- The number of levels deep the tree is being rendered. This variable along with the 'tree-level' variable can be used to calculate table rows and colspan settings when inserting table rows into the tree table. tree-state -- The tree state expressed as a list of ids and sub-lists of ids. This variable is for advanced usage only. Tag Control Variables You can control the tree tag by setting these variables. expand_all -- If this variable is true then the entire tree is expanded. collapse_all -- If this variable is true then the entire tree is collapsed.

Syntax 'in' tag syntax:: [] The 'in' block is repeated once for each item in the sequence variable or sequence expression. The current item is pushed on to the DTML namespace during each executing of the 'in' block. If there are no items in the sequence variable or expression, the optional 'else' block is executed. Attributes mapping -- Iterates over mapping objects rather than instances. This allows values of the mapping objects to be accessed as DTML variables. no_push_item -- Inhibit pushing sequence-item onto the namespace stack. reverse -- Reverses the sequence. sort=string -- Sorts the sequence by the given attribute name. start=int -- The number of the first item to be shown, where items are numbered from 1. end=int -- The number of the last item to be shown, where items are numbered from 1. size=int -- The size of the batch. skip_unauthorized -- Don't raise an exception if an unauthorized item is encountered. orphan=int -- The desired minimum batch size. This controls how sequences are split into batches. If a batch smaller than the orphan size would occur, then no split is performed, and a batch larger than the batch size results. For example, if the sequence size is 12, the batch size is 10 the orphan size is 3, then the result is one batch with all 12 items since splitting the items into two batches would result in a batch smaller than the orphan size. The default value is 0. overlap=int -- The number of items to overlap between batches. The default is no overlap. previous -- Iterates once if there is a previous batch. Sets batch variables for previous sequence. next -- Iterates once if there is a next batch. Sets batch variables for the next sequence. prefix=string -- Provide versions of the tag variables that start with this prefix instead of "sequence", and that use underscores (_) instead of hyphens (-). The prefix must start with a letter and contain only alphanumeric characters and underscores (_). sort_expr=expression -- Sorts the sequence by an attribute named by the value of the expression. This allows you to sort on different attributes. reverse_expr=expression -- Reverses the sequence if the expression evaluates to true. This allows you to selectively reverse the sequence. Tag Variables Current Item Variables These variables describe the current item. sequence-item -- The current item. sequence-key -- The current key. When looping over tuples of the form '(key,value)', the 'in' tag interprets them as '(sequence-key, sequence-item)'. sequence-index -- The index starting with 0 of the current item. sequence-number -- The index starting with 1 of the current item. sequence-roman -- The index in lowercase Roman numerals of the current item. sequence-Roman -- The index in uppercase Roman numerals of the current item. sequence-letter -- The index in lowercase letters of the current item. sequence-Letter -- The index in uppercase letters of the current item. sequence-start -- True if the current item is the first item. sequence-end -- True if the current item is the last item. sequence-even -- True if the index of the current item is even. sequence-odd -- True if the index of the current item is odd. sequence-length -- The length of the sequence. sequence-var-*variable* -- A variable in the current item. For example, 'sequence-var-title' is the 'title' variable of the current item. Normally you can access these variables directly since the current item is pushed on the DTML namespace. However these variables can be useful when displaying previous and next batch information. sequence-index-*variable* -- The index of a variable of the current item. Summary Variables These variable summarize information about numeric item variables. To use these variable you must loop over objects (like database query results) that have numeric variables. total-*variable* -- The total of all occurrences of an item variable. count-*variable* -- The number of occurrences of an item variable. min-*variable* -- The minimum value of an item variable. max-*variable* -- The maximum value of an item variable. mean-*variable* -- The mean value of an item variable. variance-*variable* -- The variance of an item variable with count-1 degrees of freedom. variance-n-*variable* -- The variance of an item variable with n degrees of freedom. standard-deviation-*variable* -- The standard-deviation of an item variable with count-1 degrees of freedom. standard-deviation-n-*variable* -- The standard-deviation of an item variable with n degrees of freedom. Grouping Variables These variables allow you to track changes in current item variables. first-*variable* -- True if the current item is the first with a particular value for a variable. last-*variable* -- True if the current item is the last with a particular value for a variable. Batch Variables sequence-query -- The query string with the 'start' variable removed. You can use this variable to construct links to next and previous batches. sequence-step-size -- The batch size. previous-sequence -- True if the current batch is not the first one. Note, this variable is only true for the first loop iteration. previous-sequence-start-index -- The starting index of the previous batch. previous-sequence-start-number -- The starting number of the previous batch. Note, this is the same as 'previous-sequence-start-index' + 1. previous-sequence-end-index -- The ending index of the previous batch. previous-sequence-end-number -- The ending number of the previous batch. Note, this is the same as 'previous-sequence-end-index' + 1. previous-sequence-size -- The size of the previous batch. previous-batches -- A sequence of mapping objects with information about all previous batches. Each mapping object has these keys 'batch-start-index', 'batch-end-index', and 'batch-size'. next-sequence -- True if the current batch is not the last batch. Note, this variable is only true for the last loop iteration. next-sequence-start-index -- The starting index of the next sequence. next-sequence-start-number -- The starting number of the next sequence. Note, this is the same as 'next-sequence-start-index' + 1. next-sequence-end-index -- The ending index of the next sequence. next-sequence-end-number -- The ending number of the next sequence. Note, this is the same as 'next-sequence-end-index' + 1. next-sequence-size -- The size of the next index. next-batches -- A sequence of mapping objects with information about all following batches. Each mapping object has these keys 'batch-start-index', 'batch-end-index', and 'batch-size'. Examples Looping over sub-objects:: title:
    Looping over two sets of objects, using prefixes::
    Looping over a list of '(key, value)' tuples:: id: , title:

Description This view displays the contained objects and allows you to add, delete and change them. Each contained object is displayed on a line and is identified by an icon, an id and a title in parenthesis. Additionally, the size (if applicable) and the date during which the object was last modified are displayed. You can manage an object by clicking on its identifying link. Sorting You can sort contained objects by type, name (id), size, or modification date. To do so, click on the appropriate column heading. Clicking a second time on any column heading will reverse the sort on that field. Controls '[Checkbox]' -- Selects the object in order to perform operations on it. The operations you can perform are rename, cut, copy, delete, and export. Some operations may not be visible if they are not allowed. 'Rename' -- Changes the ids of the selected objects. 'Cut' -- Cuts selected objects and place them into the clipboard. This is similar to cut in most file managers. Cut objects can be pasted in a new location. When cut objects are pasted into another location the old objects are deleted. 'Copy' -- Copies selected objects and place them in the clipboard. This is similar to copy in most file managers. Copied objects can be pasted in a new location. 'Paste' -- Allows you to paste objects from the clipboard into this object. **Note: This option will only appear if objects have previously been copied or cut.** 'Delete' -- Deletes the selected objects. Deleted objects are *not* placed in the clipboard. 'Import/Export' -- Imports or exports a Zope object. 'Available Objects' -- Selects a type of object to add. 'Add' -- Adds an object specified in 'Available Objects'.

Description This view gives you information about the size and location of the Zope database. The Zope database stores all Zope objects. You can reduce the size of your Zope database by packing it. Packing removes old revisions of objects, thus freeing up space but also limiting your ability to undo object changes. Controls 'Pack' -- Pack will remove all versions of objects from the Zope database. This will reduce the size of your database. **Note Pack will prevent you from undoing some or all old transactions.** You can control which old revisions of objects are removed from the database by specifying how many days old the revisions must be to be removed. If you specify 0 days old, then all old object revisions will be removed. zope2.13-2.13.21/source/Products.OFSP/src/Products/OFSP/help/Debug-Information_Profile.stx0000644000175000017500000000364612214017450027637 0ustar arnauarnauDebug Management - Profile: Performance testing. Description Zope can provide real-time profiling information. Profiling helps product authors to speed up sections of code that are taking too long to perform their tasks. In order to use profiling Zope has to be started with the 'PROFILE_PUBLISHER' environment variable set to a non-empty value. If the variable is set to a valid filesystem path, then the accumulated profile information will be dumped to the named file when Zope is shut down. If the variable is simply set to a non-empty value that is not a valid filesystem path then Zope will still run in profiling mode, but profile information will only be available through the web interface. **Note: Profiling will slow Zope performance significantly.** Once Zope has started in profiling mode visit your site with your Web browser - Zope will accumulate profiling information as you are working with your site. When you want to view the profiling information, visit the Control Panel, click on the 'Debugging information' link and select the 'Profiling' tab. The profiling screen will show a list of methods and the amount of time each method is taking. Multiple views are available by changing the sort order and pushing the "update" button. The online profiler is based on the standard Python profile module. For specific information on the meaning of the profile information, see the standard Python documentation for the 'profile' module. When you are done profiling turn profiling off by restarting Zope without the 'PROFILE_PUBLISHER' environment variable set. Controls 'Sort' -- How to sort function calls. 'Limit' -- How many function calls to display. 'Update' -- Updates the profiling information.

The 'if' tag mirrors Python's 'if/elif/else' condition testing statements. Syntax If tag syntax:: [] ... [] The 'if' tag is a block tag. The 'if' tag and optional 'elif' tags take a condition variable name or a condition expression, but not both. If the condition name or expression evaluates to true then the 'if' block is executed. True means not zero, an empty string or an empty list. If the condition variable is not found then the condition is considered false. If the initial condition is false, each 'elif' condition is tested in turn. If any 'elif' condition is true, its block is executed. Finally the optional 'else' block is executed if none of the 'if' and 'elif' conditions were true. Only one block will be executed. Examples Testing for a variable:: The snake variable is true Testing for expression conditions:: num is greater than five num is less than five num must be five See Also "Python Tutorial: If Statements":http://www.python.org/doc/current/tut/node6.html#SECTION006100000000000000000 zope2.13-2.13.21/source/Products.OFSP/src/Products/OFSP/help/DTML-Document.stx0000644000175000017500000000062012214017450025147 0ustar arnauarnauDTML Document: Content object.

Syntax The 'try' tag has two different syntaxes, 'try/except/else' and 'try/finally'. 'try/except/else' Syntax:: ... [] The 'try' tag encloses a block in which exceptions can be caught and handled. There can be one or more 'except' tags that handles zero or more exceptions. If an 'except' tag does not specify an exception, then it handles all exceptions. When an exception is raised, control jumps to the first 'except' tag that handles the exception. If there is no 'except' tag to handle the exception, then the exception is raised normally. If no exception is raised, and there is an 'else' tag, then the 'else' tag will be executed after the body of the 'try' tag. The 'except' and 'else' tags are optional. 'try/finally' Syntax:: The 'finally' tag cannot be used in the same 'try' block as the 'except' and 'else' tags. If there is a 'finally' tag, its block will be executed whether or not an exception is raised in the 'try' block. Attributes except -- Zero or more exception names. If no exceptions are listed then the except tag will handle all exceptions. Tag Variables Inside the 'except' block these variables are defined. error_type -- The exception type. error_value -- The exception value. error_tb -- The traceback. Examples Catching a math error:: You tried to divide by zero. Returning information about the handled exception:: An error occurred.

This includes, the input headers, form data, server data, and cookies. The request object is a mapping object that represents a collection of variable to value mappings. In addition, variables are divided into five categories: - Environment variables These variables include input headers, server data, and other request-related data. The variable names are as specified in the CGI specification - Form data These are data extracted from either a URL-encoded query string or body, if present. - Cookies These are the cookie data, if present. - Lazy Data These are callables which are deferred until explicitly referenced, at which point they are resolved (called) and the result stored as "other" data, ie regular request data. Thus, they are "lazy" data items. An example is SESSION objects. Lazy data in the request may only be set by the Python method set_lazy(name,callable) on the REQUEST object. This method is not callable from DTML or through the web. - Other Data that may be set by an application object. The request object may be used as a mapping object, in which case values will be looked up in the order: environment variables, other variables, form data, and then cookies. These special variables are set in the Request: 'PARENTS' -- A list of the objects traversed to get to the published object. So, 'PARENTS[0]' would be the ancestor of the published object. 'REQUEST' -- The Request object. 'RESPONSE' -- The Response object. 'PUBLISHED' -- The actual object published as a result of url traversal.

It shows how many objects were loaded and stored. You can use this information to determine the optimal memory cache size for your Zope application. You can also use it to discover applications that write to the database too often. Information 'Keep History' -- Lets you define how many seconds of history to keep for analysis. 3600 is one hour. 86400 is one day. Note that in the current implementation, analysis data is kept only in memory and is never stored to disk, so each time you restart, you lose the historical information. 'Displayed Range' -- Tells you what period of time is displayed by the chart. 'Show current chart' -- Redisplays the chart for the current time. The chart contains a bar graph. The rightmost bar shows the most recent activity. The red portion indicates the number of objects stored and the blue portion indicates the number of objects loaded during that time period. To the right of the graph there is a total. If you click on a bar, the chart will zoom in on the time period for just that bar. You will see the details of the activity during that short time period. Click the "Show current chart" button to return to the chart for the current time. How to use this information Once Zope has loaded enough objects, the ZODB cache consistently keeps in the cache the number of objects you specify under the "Cache Parameters" tab. Because the cache size is so consistent and ZODB is so transparent to both the user and application developer, Zope applications can invisibly develop a performance problem by loading objects from ZODB on every request. Also, if the cache size is set too high, Zope will consume more RAM than it needs. You need to find a good balance that fits your site. If the bar chart shows a large number of objects being loaded all the time, increase the cache size, which will increase memory usage but should also increase performance. If the chart shows little activity even though the site is visited frequently, you can reduce the cache size so Zope will consume less RAM. As your site changes, its cache size requirements may change also, so remember to make adjustments over time. If the graph shows a lot of writes (a significant portion of red), some application or product may be writing to the database too frequently. Check the "undo" log for clues. Note that the activity graph does not show activity in mounted databases, so objects loaded and stored by the sessioning machinery are not counted in the graph. zope2.13-2.13.21/source/Products.OFSP/src/Products/OFSP/help/dtml-let.stx0000644000175000017500000000236712214017450024367 0ustar arnauarnaulet: Defines DTML variables The 'let' tag defines variables in the DTML namespace.

It is used to build SQL queries. The 'sqltest' tag correctly escapes the inserted variable. The named variable or variable expression is tested against a SQL column using the specified comparison operation. Attributes type=string -- The type of the variable. Valid types include: 'string', 'int', 'float' and 'nb'. 'nb' means non-blank string, and should be used instead of 'string' unless you want to test for blank values. The type attribute is required and is used to properly escape inserted variable. column=string -- The name of the SQL column to test against. This attribute defaults to the variable name. multiple=boolean -- If true, then the variable may be a sequence of values to test the column against. optional=boolean -- If true, then the test is optional and will not be rendered if the variable is empty or non-existent. op=string -- The comparison operation. Valid comparisons include: eq -- equal to gt -- greater than lt -- less than ne -- not equal to ge -- greater than or equal to le -- less than or equal to The comparison defaults to equal to.

Description This view allows you to view Zope database cache statistics and set cache parameters. The Zope database cache operates by keeping recently used objects in memory to improve performance. A large cache improves object access speed, but increases memory usage. A small cache reduces memory usage but may slow down object access speed. Information 'Total number of objects in the database' -- Indicates the number of persistent objects in the Zope database. All of these objects are stored on disk, some of them are in memory too. 'Total number of objects in memory from all caches' -- Indicates the number of objects which are currently cached in memory. This is a good indication of the amount of memory used by Zope. 'Target number of objects in memory per cache' -- Indicates the target number of objects to have in each cache at any given time. Zope will allow the number of objects to grow above this number while processing a request, but will always reduce the level to this number at the end of each request. This parameter is one factor affecting the amount of memory use by Zope. It controls the amount of memory used per cache, the other factor is the number of caches. In general, Zope uses one cache per worker thread (specified by the '-t' switch on the command line) 'Total number of objects in each cache' -- This table displays one row for each object cache. 'Number of objects in memory' -- This value should not stay larger than the configured target size for longer than one transaction. Note that the total number at the bottom of this column should be the same as the figure in the top half of the page. It may be slightly different because there is a small time interval between the calculation of the two totals. 'Number of ghost objects' -- Ghost objects are those which only have a tiny memory footprint because their full state has not been loaded. You generally do not need to worry about the number of ghost objects because they are so small. zope2.13-2.13.21/source/Products.OFSP/src/Products/OFSP/help/dtml-with.stx0000644000175000017500000000222112214017450024543 0ustar arnauarnauwith: Controls DTML variable look up The 'with' tag pushes an object onto the DTML namespace.

Description This view displays the contained objects and allows you to add, delete, change and order them. Each contained object is displayed on a line and is identified by an icon, an id and a title in parenthesis. Additionally, the size (if applicable) and the date during which the object was last modified are displayed. You can manage an object by clicking on its identifying link. Sorting vs. Ordering You can sort contained objects by type, name (id), size, modification date or by position (fixed order, see below). To do so, click on the appropriate column heading. Clicking a second time on any column heading (except position) will reverse the sort on that field. Sorting takes no actions on the contained objects, but will only change the users personal point of view. You can order contained objects with the controls on the bottom of the page. The order of objects ('sort by position') is stored in the database and remains fixed until it is changed by another user. Controls '[Checkbox]' -- Selects the object in order to perform operations on it. The operations you can perform are rename, cut, copy, delete, and export. Some operations may not be visible if they are not allowed. 'Rename' -- Changes the ids of the selected objects. 'Cut' -- Cuts selected objects and place them into the clipboard. This is similar to cut in most file managers. Cut objects can be pasted in a new location. When cut objects are pasted into another location the old objects are deleted. 'Copy' -- Copies selected objects and place them in the clipboard. This is similar to copy in most file managers. Copied objects can be pasted in a new location. 'Paste' -- Allows you to paste objects from the clipboard into this object. **Note: This option will only appear if objects have previously been copied or cut.** 'Delete' -- Deletes the selected objects. Deleted objects are *not* placed in the clipboard. 'Import/Export' -- Imports or exports a Zope object. 'Available Objects' -- Selects a type of object to add. 'Add' -- Adds an object specified in 'Available Objects'. 'Select All (Deselect All)' -- Toggles between selecting and deselecting each item currently displayed in the contents view. **Note: This control will only appear if your browser is javascript-enabled.** 'Set View as Default' -- Sets current sorted view as default contents view for this folder. **Note: This option will only appear if your current sorted view is not the default view.** **The following options will only appear in Position view:** 'Up' -- Moves selected objects up by the selected amount of steps (default is 1).

Functions abs(number) -- Return the absolute value of a number. The argument may be a plain or long integer or a floating point number. If the argument is a complex number, its magnitude is returned. chr(integer) -- Return a string of one character whose ASCII code is the integer, e.g., 'chr(97)' returns the string 'a'. This is the inverse of ord(). The argument must be in the range 0 to 255, inclusive; 'ValueError' will be raised if the integer is outside that range. DateTime() -- Returns a Zope 'DateTime' object given constructor arguments. See the "DateTime":DateTime.py API reference for more information on constructor arguments. divmod(number, number) -- Take two numbers as arguments and return a pair of numbers consisting of their quotient and remainder when using long division. With mixed operand types, the rules for binary arithmetic operators apply. For plain and long integers, the result is the same as '(a / b, a % b)'. For floating point numbers the result is '(q, a % b)', where *q* is usually 'math.floor(a / b)' but may be 1 less than that. In any case 'q * b + a % b' is very close to *a*, if 'a % b' is non-zero it has the same sign as *b*, and '0 <= abs(a % b) < abs(b)'. float(number) -- Convert a string or a number to floating point. If the argument is a string, it must contain a possibly signed decimal or floating point number, possibly embedded in whitespace; this behaves identical to 'string.atof(number)'. Otherwise, the argument may be a plain or long integer or a floating point number, and a floating point number with the same value (within Python's floating point precision) is returned. getattr(object, string) -- Return the value of the named attributed of object. name must be a string. If the string is the name of one of the object's attributes, the result is the value of that attribute. For example, 'getattr(x, "foobar")' is equivalent to 'x.foobar'. If the named attribute does not exist, default is returned if provided, otherwise 'AttributeError' is raised. getitem(variable, render=0) -- Returns the value of a DTML variable. If 'render' is true, the variable is rendered. See the 'render' function. hasattr(object, string) -- The arguments are an object and a string. The result is 1 if the string is the name of one of the object's attributes, 0 if not. (This is implemented by calling getattr(object, name) and seeing whether it raises an exception or not.) hash(object) -- Return the hash value of the object (if it has one). Hash values are integers. They are used to quickly compare dictionary keys during a dictionary lookup. Numeric values that compare equal have the same hash value (even if they are of different types, e.g. 1 and 1.0). has_key(variable) -- Returns true if the DTML namespace contains the named variable. hex(integer) -- Convert an integer number (of any size) to a hexadecimal string. The result is a valid Python expression. Note: this always yields an unsigned literal, e.g. on a 32-bit machine, 'hex(-1)' yields '0xffffffff'. When evaluated on a machine with the same word size, this literal is evaluated as -1; at a different word size, it may turn up as a large positive number or raise an 'OverflowError' exception. int(number) -- Convert a string or number to a plain integer. If the argument is a string, it must contain a possibly signed decimal number representable as a Python integer, possibly embedded in whitespace; this behaves identical to 'string.atoi(number[, radix]'). The 'radix' parameter gives the base for the conversion and may be any integer in the range 2 to 36. If 'radix' is specified and the number is not a string, 'TypeError' is raised. Otherwise, the argument may be a plain or long integer or a floating point number. Conversion of floating point numbers to integers is defined by the C semantics; normally the conversion truncates towards zero. len(sequence) -- Return the length (the number of items) of an object. The argument may be a sequence (string, tuple or list) or a mapping (dictionary). max(s) -- With a single argument s, return the largest item of a non-empty sequence (e.g., a string, tuple or list). With more than one argument, return the largest of the arguments. min(s) -- With a single argument s, return the smallest item of a non-empty sequence (e.g., a string, tuple or list). With more than one argument, return the smallest of the arguments. namespace([name=value]...) -- Returns a new DTML namespace object. Keyword argument 'name=value' pairs are pushed into the new namespace. oct(integer) -- Convert an integer number (of any size) to an octal string. The result is a valid Python expression. Note: this always yields an unsigned literal, e.g. on a 32-bit machine, 'oct(-1)' yields '037777777777'. When evaluated on a machine with the same word size, this literal is evaluated as -1; at a different word size, it may turn up as a large positive number or raise an OverflowError exception. ord(character) -- Return the ASCII value of a string of one character. E.g., 'ord("a")' returns the integer 97. This is the inverse of 'chr()'. pow(x, y [,z]) -- Return *x* to the power *y*; if *z* is present, return *x* to the power *y*, modulo *z* (computed more efficiently than 'pow(x, y) % z'). The arguments must have numeric types. With mixed operand types, the rules for binary arithmetic operators apply. The effective operand type is also the type of the result; if the result is not expressible in this type, the function raises an exception; e.g., 'pow(2, -1)' or 'pow(2, 35000)' is not allowed. range([start,] stop [,step]) -- This is a versatile function to create lists containing arithmetic progressions. The arguments must be plain integers. If the step argument is omitted, it defaults to 1. If the start argument is omitted, it defaults to 0. The full form returns a list of plain integers '[start, start + step, start + 2 * step, ...]'. If step is positive, the last element is the largest 'start + i * step' less than *stop*; if *step* is negative, the last element is the largest 'start + i * step' greater than *stop*. *step* must not be zero (or else 'ValueError' is raised). round(x [,n]) -- Return the floating point value *x* rounded to *n* digits after the decimal point. If n is omitted, it defaults to zero. The result is a floating point number. Values are rounded to the closest multiple of 10 to the power minus n; if two multiples are equally close, rounding is done away from 0 (so e.g. round(0.5) is 1.0 and round(-0.5) is -1.0). render(object) -- Render 'object'. For DTML objects this evaluates the DTML code with the current namespace. For other objects, this is equivalent to 'str(object)'. reorder(s [,with] [,without]) -- Reorder the items in s according to the order given in 'with' and without the items mentioned in 'without'. Items from s not mentioned in with are removed. s, with, and without are all either sequences of strings or sequences of key-value tuples, with ordering done on the keys. This function is useful for constructing ordered select lists. SecurityCalledByExecutable() -- Return a true if the current object (e.g. DTML document or method) is being called by an executable (e.g. another DTML document or method or script). SecurityCheckPermission(permission, object) -- Check whether the security context allows the given permission on the given object. For example, 'SecurityCheckPermission("Add Documents, Images, and Files", this())' would return true if the current user was authorized to create documents, images, and files in the current location. SecurityGetUser() -- Return the current user object. This is normally the same as the 'REQUEST.AUTHENTICATED_USER' object. However, the 'AUTHENTICATED_USER' object is insecure since it can be replaced. SecurityValidate([object] [,parent] [,name] [,value]) -- Return true if the value is accessible to the current user. 'object' is the object the value was accessed in, 'parent' is the container of the value, and 'name' is the named used to access the value (for example, if it was obtained via 'getattr'). You may omit some of the arguments, however it is best to provide all available arguments. SecurityValidateValue(object) -- Return true if the object is accessible to the current user. This function is the same as calling 'SecurityValidate(None, None, None, object)'. str(object) -- Return a string containing a nicely printable representation of an object. For strings, this returns the string itself. test(condition, result [,condition, result]... [,default]) -- Takes one or more condition, result pairs and returns the result of the first true condition. Only one result is returned, even if more than one condition is true. If no condition is true and a default is given, the default is returned. If no condition is true and there is no default, None is returned. unichr(number) -- Return a unicode string representing the value of number as a unicode character. This is the inverse of ord() for unicode characters. unicode(string[, encoding[, errors ] ]) -- Decodes string using the codec for encoding. Error handling is done according to errors. The default behavior is to decode UTF-8 in strict mode, meaning that encoding errors raise ValueError. Attributes None -- The 'None' object is equivalent to the Python built-in object 'None'. This is usually used to represent a Null or false value.

DateTime also provides methods for calendar operations, date and time arithmetic and formatting. DateTime objects represent instants in time and provide interfaces for controlling its representation without affecting the absolute value of the object. DateTime objects may be created from a wide variety of string or numeric data, or may be computed from other DateTime objects. DateTimes support the ability to convert their representations to many major timezones, as well as the ability to create a DateTime object in the context of a given timezone. DateTime objects provide partial numerical behavior: - Two date-time objects can be subtracted to obtain a time, in days between the two. - A date-time object and a positive or negative number may be added to obtain a new date-time object that is the given number of days later than the input date-time object. - A positive or negative number and a date-time object may be added to obtain a new date-time object that is the given number of days later than the input date-time object. - A positive or negative number may be subtracted from a date-time object to obtain a new date-time object that is the given number of days earlier than the input date-time object. DateTime objects may be converted to integer, long, or float numbers of days since January 1, 1901, using the standard int, long, and float functions (Compatibility Note: int, long and float return the number of days since 1901 in GMT rather than local machine timezone). DateTime objects also provide access to their value in a float format usable with the python time module, provided that the value of the object falls in the range of the epoch-based time module. A DateTime object should be considered immutable; all conversion and numeric operations return a new DateTime object rather than modify the current object. A DateTime object always maintains its value as an absolute UTC time, and is represented in the context of some timezone based on the arguments used to create the object. A DateTime object's methods return values based on the timezone context. Note that in all cases the local machine timezone is used for representation if no timezone is specified. DateTimes may be created with from zero to seven arguments. - If the function is called with no arguments, then the current date/time is returned, represented in the timezone of the local machine. - If the function is invoked with a single string argument which is a recognized timezone name, an object representing the current time is returned, represented in the specified timezone. - If the function is invoked with a single string argument representing a valid date/time, an object representing that date/time will be returned. As a general rule, any date-time representation that is recognized and unambiguous to a resident of North America is acceptable.(The reason for this qualification is that in North America, a date like: 2/1/1994 is interpreted as February 1, 1994, while in some parts of the world, it is interpreted as January 2, 1994.) A date/time string consists of two components, a date component and an optional time component, separated by one or more spaces. If the time component is omitted, 12:00am is assumed. Any recognized timezone name specified as the final element of the date/time string will be used for computing the date/time value. (If you create a DateTime with the string 'Mar 9, 1997 1:45pm US/Pacific', the value will essentially be the same as if you had captured time.time() at the specified date and time on a machine in that timezone):: e=DateTime("US/Eastern") # returns current date/time, represented in US/Eastern. x=DateTime("1997/3/9 1:45pm") # returns specified time, represented in local machine zone. y=DateTime("Mar 9, 1997 13:45:00") # y is equal to x The date component consists of year, month, and day values. The year value must be a one-, two-, or four-digit integer. If a one- or two-digit year is used, the year is assumed to be in the twentieth century. The month may be an integer, from 1 to 12, a month name, or a month abbreviation, where a period may optionally follow the abbreviation. The day must be an integer from 1 to the number of days in the month. The year, month, and day values may be separated by periods, hyphens, forward slashes, or spaces. Extra spaces are permitted around the delimiters. Year, month, and day values may be given in any order as long as it is possible to distinguish the components. If all three components are numbers that are less than 13, then a month-day-year ordering is assumed. The time component consists of hour, minute, and second values separated by colons. The hour value must be an integer between 0 and 23 inclusively. The minute value must be an integer between 0 and 59 inclusively. The second value may be an integer value between 0 and 59.999 inclusively. The second value or both the minute and second values may be omitted. The time may be followed by am or pm in upper or lower case, in which case a 12-hour clock is assumed. - If the DateTime function is invoked with a single Numeric argument, the number is assumed to be a floating point value such as that returned by time.time(). A DateTime object is returned that represents the gmt value of the time.time() float represented in the local machine's timezone. - If the function is invoked with two numeric arguments, then the first is taken to be an integer year and the second argument is taken to be an offset in days from the beginning of the year, in the context of the local machine timezone. The date-time value returned is the given offset number of days from the beginning of the given year, represented in the timezone of the local machine. The offset may be positive or negative. Two-digit years are assumed to be in the twentieth century. - If the function is invoked with two arguments, the first a float representing a number of seconds past the epoch in gmt (such as those returned by time.time()) and the second a string naming a recognized timezone, a DateTime with a value of that gmt time will be returned, represented in the given timezone.:: import time t=time.time() now_east=DateTime(t,'US/Eastern') # Time t represented as US/Eastern now_west=DateTime(t,'US/Pacific') # Time t represented as US/Pacific # now_east == now_west # only their representations are different - If the function is invoked with three or more numeric arguments, then the first is taken to be an integer year, the second is taken to be an integer month, and the third is taken to be an integer day. If the combination of values is not valid, then a DateTimeError is raised. Two-digit years are assumed to be in the twentieth century. The fourth, fifth, and sixth arguments specify a time in hours, minutes, and seconds; hours and minutes should be positive integers and seconds is a positive floating point value, all of these default to zero if not given. An optional string may be given as the final argument to indicate timezone (the effect of this is as if you had taken the value of time.time() at that time on a machine in the specified timezone). New in Zope 2.7: A new keyword parameter "datefmt" can be passed to the constructor. If set to "international", the constructor is forced to treat ambigious dates as "days before month before year". This useful if you need to parse non-US dates in a reliable way If a string argument passed to the DateTime constructor cannot be parsed, it will raise DateTime.SyntaxError. Invalid date, time, or timezone components will raise a DateTime.DateTimeError. The module function Timezones() will return a list of the timezones recognized by the DateTime module. Recognition of timezone names is case-insensitive. """ def timeTime(): """ Return the date/time as a floating-point number in UTC, in the format used by the python time module.

The beginning of the block describes the email headers. The headers are separated from the body by a blank line. Alternately the 'To', 'From' and 'Subject' headers can be set with tag arguments. Attributes mailhost -- The name of a Zope MailHost object to use to send email. You cannot specify both a mailhost and a smtphost. smtphost -- The name of a SMTP server used to send email. You cannot specify both a mailhost and a smtphost. port -- If the smtphost attribute is used, then the port attribute is used to specify a port number to connect to. If not specified, then port 25 will be used. mailto -- The recipient address or a list of recipient addresses separated by commas. This can also be specified with the 'To' header. mailfrom -- The sender address. This can also be specified with the 'From' header. subject -- The email subject.

Description This view allows you to reload filesystem-based product code without restarting Zope. This function is useful during development of products. To enable your product to be refreshed, it is required that you put a file called 'refresh.txt' in your product directory. It can optionally contain a warning for others who might use the refresh function. (Producting refreshing is not perfect. Some products, especially "hotfix" style products which patch Zope, should not be refreshed. That's why 'refresh.txt' is required. Most products are safe to refresh, however.) There are two modes of operation. You can visit your product's 'Refresh' tab and manually push the refresh button. Or you can turn on "auto-refresh" mode, which causes Zope to periodically scan the modification time of the Python files that make up your product and execute a refresh operation in the background. **NOTE**: Don't enable auto-refresh for too many products at once. Scanning file modification times can take a lot of time per request. You can also select dependent refreshable products. If you have a product that subclasses from a product you're working on, you'll want to enable refresh for both products and add the product that subclasses as a dependent of the product you're modifying. This enables subclasses to be updated. Controls 'Refresh this product' -- The manual refresh button. 'Auto refresh mode' -- Check the checkbox to enable auto-refresh. 'Dependent auto-refreshable products' -- A list of other products which are auto-refreshable. How it works To execute a refresh, Zope looks in the sys.modules dictionary for modules with names that start with the prefix for your product. It tries to scan for dependencies between the modules that make up your product then uses Python's reload() function for each module in order. Then it sets a flag that will cause ZODB to dump its cache on the next connection so that changes to persistent classes will take effect. To implement auto-refresh, Zope stores a PersistentMapping called RefreshData on the database root object (below the Application object). The contents of the PersistentMapping are examined at the moment a database connection is opened by ZApplication. The PersistentMapping contains a list of which products have auto-refresh enabled. For each product with auto-refresh enabled, Zope compares the file mod times with the last recorded times and executes a refresh if there are any changes. zope2.13-2.13.21/source/Products.OFSP/src/Products/OFSP/help/dtml-mime.stx0000644000175000017500000000460412214017450024526 0ustar arnauarnaumime: Formats data with MIME The 'mime' tag allows you to create MIME encoded data. It is chiefly used to format email inside the 'sendmail' tag. Syntax 'mime' tag syntax:: [] ... The 'mime' tag is a block tag. The block is can be divided by one or more 'boundry' tags to create a multi-part MIME message. 'mime' tags may be nested. The 'mime' tag is most often used inside the 'sendmail' tag. Attributes Both the 'mime' and 'boundry' tags have the same attributes. encode=string -- MIME Content-Transfer-Encoding header, defaults to 'base64'. Valid encoding options include 'base64', 'quoted-printable', 'uuencode', 'x-uuencode', 'uue', 'x-uue', and '7bit'. If the 'encode' attribute is set to '7bit' no encoding is done on the block and the data is assumed to be in a valid MIME format. type=string -- MIME Content-Type header. type_expr=string -- MIME Content-Type header as a variable expression. You cannot use both 'type' and 'type_expr'. name=string -- MIME Content-Type header name. name_expr=string -- MIME Content-Type header name as a variable expression. You cannot use both 'name' and 'name_expr'. disposition=string -- MIME Content-Disposition header. disposition_expr=string -- MIME Content-Disposition header as a variable expression. You cannot use both 'disposition' and 'disposition_expr'. filename=string -- MIME Content-Disposition header filename. filename_expr=string -- MIME Content-Disposition header filename as a variable expression.

Description Proxy roles control security for DTML Documents and Methods. Normally a DTML Document or Method executes with an intersection of the owner's and viewer's roles. This means that the DTML can only perform actions that are available to both the owner and viewer. Proxy roles explicitly list the roles that a DTML Document or Method will execute with.

Debugging Information * The Zope version * The Python version * The system platform name * The filesystem path of the Zope core software, add-on software, and data files. * The ID number of the Zope process (if available on your platform) * The length of time Zope has been running * The Python module search paths (sys.path). * The top refcounts, including a table listing the changes since * the last snapshot * The open object database connections The Zope version, Python version, and system platform name are used to verify compatibility between Zope, Python, and your system. On platforms where the process ID number is available, the Zope process can be managed using a more forceful means than is available through the web. Refcounts The top refcounts list lets you take a look at what is being stored by Zope in memory. The scrollable list shows how many instances of each type of object are currently in memory. If there are items in the list with a very high refcount, there is a good chance there is a memory leak in a product or in Zope. Using the snapshot and refresh options allow you to determine which operations are causing memory leaks. Open Connections A database connection usually corresponds with an HTTP request. The left column shows the time at which the connection was opened. If there is a request that has been running for a long time you may need to restart Zope to kill the corresponding thread. The middle column usually shows the state of the REQUEST object with size of the cache for that connection in parentheses. The right column shows information about the version the user is working in. Controls 'Update Snapshot' -- Takes the current refcounts and store them in memory. Then each time the debugging page is reloaded, the table will show the difference in refcounts between the snapshot and the current state. 'Refresh' -- Reloads and updates the debugging information. 'Auto refresh interval' -- The number of seconds to wait before automatically refreshing the debugging information. 'Start auto refresh' -- Begins automatically refreshing the debugging information.

This tag is used in SQL Methods. Syntax 'sqlvar' tag syntax:: The 'sqlvar' tag is a singleton. Like the 'var' tag, the 'sqlvar' tag looks up a variable and inserts it. Unlike the var tag, the formatting options are tailored for SQL code. Attributes type=string -- The type of the variable. Valid types include: 'string', 'int', 'float' and 'nb'. 'nb' means non-blank string and should be used in place of 'string' unless you want to use blank strings.

If no encoding is specified, 'base64' is defaulted. Valid encoding options include 'base64', 'quoted-printable', 'uuencode', 'x-uuencode', 'uue' and 'x-uue'. If the 'encode' attribute is set to '7bit' no encoding is done on the block and the data is assumed to be in a valid MIME format.

This allows Zope to send attachments along with email. Here is an example. Create a DTML method called 'input' with the following code::

    Send to:
    Create another DTML Method called 'send' with the following code:: From: michel@digicool.com To: Hi , someone sent you this attachment. Mail with attachment was sent. Notice that there is no blank line between the 'To:' header and the starting #mime tag. If a blank line is inserted between them then the message will not be interpreted as multipart by the receiving mail reader. Also notice that there is no newline between the #boundary tag and the #var tag, or the end of the #var tag and the closing #mime tag. This is important, if you break the tags up with newlines then they will be encoded and included in the MIME part, which is probably not what you're after. As per the MIME spec, #mime tags may be nested within #mime tags arbitrarily.

The ```` tag is used to construct MIME containers. The syntax of the ```` tag is:: Contents of first part Contents of second part Contents of nth part The area of data between tags, called a block, is encoded into whatever is specified with the 'encode' tag attribute for that block. If no encoding is specified, 'base64' is defaulted. Valid encoding options include 'base64', 'quoted-printable', 'uuencode', 'x-uuencode', 'uue' and 'x-uue'. If the 'encode' attribute is set to '7bit' no encoding is done on the block and the data is assumed to be in a valid MIME format. If the 'disposition' attribute is not specified for a certain block, then the 'Content-Disposition:' MIME header is not included in that block's MIME part. The entire MIME container, from the opening mime tag to the closing, has it's 'Content-Type:' MIME header set to 'multipart/mixed'. For example, the following DTML:: This is the first part. This is the second. Is rendered to the following text:: Content-Type: multipart/mixed; boundary="216.164.72.30.501.1550.923070182.795.22531" --216.164.72.30.501.1550.923070182.795.22531 Content-Type: text/plain Content-Transfer-Encoding: 7bit This is the first part. --216.164.72.30.501.1550.923070182.795.22531 Content-Type: text/plain Content-Transfer-Encoding: base64 VGhpcyBpcyB0aGUgc2Vjb25kLgo= --216.164.72.30.501.1550.923070182.795.22531-- The #mime tag is particularly handy in conjunction with the ``#sendmail`` tag.
