Release Notes

The following are the release notes for Buildbot |version|.

Master

Deprecations, Removals, and Non-Compatible Changes

  • Forced builds now require that a :bb:sched:`ForceScheduler` be defined in the Buildbot configuration. For compatible behavior, this should look like:

    from buildbot.schedulers.forcesched import ForceScheduler
c['schedulers'].append(ForceScheduler(
                        name="force",
                        builderNames=["b1", "b2", ... ]))

    Where all of the builder names in the configuration are listed. See the documentation for the much more flexiblie configuration options now available.

  • buildbot start no longer invokes make if a Makefile.buildbot exists. If you are using this functionality, consider invoking make directly.

  • The buildbot sendchange option --username has been removed as promised in :bb🐛`1711`.

  • StatusReceivers' checkConfig method should now take an additional errors parameter and call its :py:meth:`~buildbot.config.ConfigErrors.addError` method to indicate errors.

  • The gerrit status callback now gets an additional parameter (the master status). If you use this callback, you will need to adjust its implementation.

  • This is the last release of Buildbot that will be compatible with Python 2.4. The next version will minimally require Python-2.5.

  • SQLAlchemy-Migrate version 0.6.0 is no longer supported. See :ref:`Buildmaster-Requirements`.

  • Older versions of SQLite which could limp along for previous versions of Buildbot are no longer supported. The minimum version is 3.4.0, and 3.7.0 or higher is recommended.

  • The master-side Git step now checks out 'HEAD' by default, rather than master, which translates to the default branch on the upstream repository. See :bb:pull:`301`.

Changes for Developers

Features

  • Buildbot can now take advantage of authentication done by a front-end web server - see :bb:pull:`266`.

  • Buildbot supports a simple cookie-based login system, so users no longer need to enter a username and password for every request. See the earlier commits in :bb:pull:`278`.

  • The master-side SVN step now has an export method which is similar to copy, but the build directory does not contain Subversion metdata. (:bb🐛`2078`)

  • :py:class:`Property` instances will now render any properties in the default value if necessary. This makes possible constructs like

    command=Property('command', default=Property('default-command'))

  • Buildbot has a new web hook to handle push notifications from Google Code - see :bb:pull:`278`.

  • Revision links are now generated by a flexible runtime conversion configured by :bb:cfg:`revlink` - see :bb:pull:`280`.

  • Shell command steps will now "flatten" nested lists in the command argument. This allows substitution of multiple command-line arguments using properties. See :bb🐛`2150`.

  • Steps now take an optional hideStepIf parameter to suppress the step from the waterfall and build details in the web. (:bb🐛`1743`)

  • :py:class:`Trigger` steps with waitForFinish=True now receive a URL to all the triggered builds. This URL is displayed in the waterfall and build details. See :bb🐛`2170`.

  • The bb:src:master/contrib/fakemaster.py` script allows you to run arbitrary commands on a slave by emulating a master. See the file itself for documentation.
