Change History for ZConfig

3.4.1 (unreleased)

  • TBD

3.4.0 (2019-01-02)

Many changes have been made in the support for logging configurations:

  • The log handler section types defined by the ZConfig.components.logger package support additional, optional parameters:

    style

    Used to configure alternate format styles as found in the Python 3 standard library. Four style values are supported: classic (the default), format (equivalent to style='{' in Python 3), template (equivalent to style='$'), and safe-template (similar to template, but using the string.Template method safe_substitute method). A best-effort implementation is provided for Python 2.

    arbitrary-fields

    A Boolean defauting to False for backward compatibility, allows arbitrary replacement field names to be accepted in the format string (regardless of the style setting). This supports applications where log records are known to be generated with additional string or numeric fields, at least for some loggers. (An exception is still raised at format time if the additional fields are not provided, unless the style value safe-template is used.)

  • The logfile section type defined by the ZConfig.components.logger package supports the optional delay and encoding parameters. These can only be used for regular files, not the special STDOUT and STDERR streams.

  • More validation on the parameters to the logfile and email-notifier sections is performed early (at the construction of the factory, rather than at creation of the logging handler). This allows more checking of parameter combinations before any log files are opened.

  • The ZConfig.components.logger.handlers.log_format data type function now supports formats that include numeric formatting for levelno, and accept funcName as a valid log record field (added in Python 2.6 and 3.1).

3.3.0 (2018-10-04)

  • Drop support for Python 3.3.
  • Add support for Python 3.7.
  • Drop support for ‘python setup.py test’. See issue 38.
  • Add support for example in section and multisection, and include those examples in generated documentation. See https://github.com/zopefoundation/ZConfig/pull/5.
  • Fix configuration loaders to decode byte data using UTF-8 instead of the default encoding (usually ASCII). See issue 37.

3.2.0 (2017-06-22)

3.1.0 (2015-10-17)

  • Add ability to do variable substitution from environment variables using $() syntax.

3.0.4 (2014-03-20)

  • Added Python 3.4 support.

3.0.3 (2013-03-02)

  • Added Python 3.2 support.

3.0.2 (2013-02-14)

  • Fixed ResourceWarning in BaseLoader.openResource().

3.0.1 (2013-02-13)

  • Removed an accidentally left pdb statement from the code.
  • Fix a bug in Python 3 with the custom string repr() function.

3.0.0 (2013-02-13)

  • Added Python 3.3 support.
  • Dropped Python 2.4 and 2.5 support.

2.9.3 (2012-06-25)

  • Fixed: port values of 0 weren’t allowed. Port 0 is used to request an ephemeral port.

2.9.2 (2012-02-11)

  • Adjust test classes to avoid base classes being considered separate test cases by (at least) the “nose” test runner.

2.9.1 (2012-02-11)

  • Make FileHandler.reopen thread safe.

2.9.0 (2011-03-22)

  • Allow identical redefinition of %define names.
  • Added support for IPv6 addresses.

2.8.0 (2010-04-13)

2.7.1 (2009-06-13)

  • Improved documentation
  • Fixed tests failures on windows.

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.

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.

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.

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.

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.

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.

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 <section> and <multisection>, if the name attribute is omitted, assume name=”*”, since this is what is used most often.

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 <default> 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.

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 <key name=”+”> and <multikey name=”+”> by using <default key=”…”>.
  • 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.
  • <import package=’…’/> 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.

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 <schema> 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.

1.0 (2003-03-25)

  • Initial release.
