| Release Notes for Buildbot v0.8.8 | ||
| ================================= | ||
|
|
||
| .. | ||
| Any change that adds a feature or fixes a bug should have an entry here. | ||
| Most simply need an additional bulleted list item, but more significant | ||
| changes can be given a subsection of their own. | ||
| The following are the release notes for Buildbot v0.8.8. | ||
| This version was released XXX. | ||
|
|
||
| * The ``MasterShellCommand`` step now correctly handles environment variables passed as list. | ||
| * The master now poll the database for pending tasks when running buildbot in multi-master mode. | ||
|
|
||
| Master | ||
| ------ | ||
|
|
||
| Features | ||
| ~~~~~~~~ | ||
|
|
||
| * The algorithm to match build requests to slaves has been rewritten in :bb:pull:`615`. | ||
| The new algorithm automatically takes locks into account, and will not schedule a build only to have it wait on a lock. | ||
| The algorithm also introduces a ``canStartBuild`` builder configuration option which can be used to prevent a build request being assigned to a slave. | ||
|
|
||
| * ``buildbot stop`` and ``buildbot restart`` now accept ``--clean`` to stop or restart the master cleanly (allowing all running builds to complete first). | ||
|
|
||
| * The :bb:status:`IRC` bot now supports clean shutdown and immediate shutdown by using the command 'shutdown'. | ||
| To allow the command to function, you must provide `allowShutdown=True`. | ||
|
|
||
| * :bb:step:`CopyDirectory` has been added. | ||
|
|
||
| * :bb:sched:`BuildslaveChoiceParameter` has been added to provide a way to explicitly choose a buildslave | ||
| for a given build. | ||
|
|
||
| * default.css now wraps preformatted text by default. | ||
|
|
||
| * Slaves can now be paused through the web status. | ||
|
|
||
| * The latent buildslave support is less buggy, thanks to :bb:pull:`646`. | ||
|
|
||
| * The ``treeStableTimer`` for ``AnyBranchScheduler`` now maintains separate timers for separate branches, codebases, projects, and repositories. | ||
|
|
||
| * :bb:step:`SVN` has a new option `preferLastChangedRev=True` to use the last changed revision for ``got_revision`` | ||
|
|
||
| * The build request DB connector method :py:meth:`~buildbot.db.buildrequests.BuildRequestsConnectorComponent.getBuildRequests` can now filter by branch and repository. | ||
|
|
||
| * A new :bb:step:`SetProperty` step has been added in ``buildbot.steps.master`` which can set a property directly without accessing the slave. | ||
|
|
||
| * The new :bb:step:`LogRenderable` step logs Python objects, which can contain renderables, to the logfile. | ||
| This is helpful for debugging property values during a build. | ||
|
|
||
| * 'buildbot try' now has an additional :option:`--property` option to set properties. | ||
| Unlike the existing :option:`--properties` option, this new option supports setting | ||
| only a single property and therefore allows commas to be included in the property | ||
| name and value. | ||
|
|
||
| * The ``Git`` step has a new ``config`` option, which accepts a dict of git configuration options to pass to the low-level git commands. | ||
| See :bb:step:`Git` for details. | ||
|
|
||
| * The ``TryScheduler`` now accepts an additional ``properties`` argument to its | ||
| ``getAvailableBuilderNames`` method, which 'buildbot try' uses to send the properties | ||
| it was passed (and are normally sent when starting a build). | ||
|
|
||
| * In :bb:step:`ShellCommand` ShellCommand now validates its arguments during config and will identify any invalid arguments before a build is started. | ||
|
|
||
| * The list of force schedulers in the web UI is now sorted by name. | ||
|
|
||
| * The :bb:step:`ShellCommand` step has a new parameter ``user``. | ||
| When this is set, the slave will use 'sudo' to run the command as the given user. | ||
|
|
||
| * OpenStack-based Latent Buildslave support was added. | ||
| See :bb:pull:`666`. | ||
|
|
||
| * Master-side support for P4 is available, and provides a great deal more flexibility than the old slave-side step. | ||
| See :bb:pull:`596`. | ||
|
|
||
| Deprecations, Removals, and Non-Compatible Changes | ||
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
|
|
||
| * The ``split_file`` function for :bb:chsrc:`SVNPoller` may now return a dictionary instead of a tuple. | ||
| This allows it to add extra information about a change (such as ``project`` or ``repository``). | ||
|
|
||
| * The ``workdir`` build property has been renamed to ``builddir``. | ||
| This change accurately reflects its content; the term "workdir" means something different. | ||
|
|
||
| * The ``Blocker`` step has been removed. | ||
|
|
||
| * Several polling ChangeSources are now documented to take a ``pollInterval`` argument, instead of ``pollinterval``. | ||
| The old name is still supported. | ||
|
|
||
| * StatusReceivers' checkConfig method should no longer take an `errors` parameter. | ||
| It should indicate errors by calling :py:func:`~buildbot.config.error`. | ||
|
|
||
| * Build steps now require that their name be a string. | ||
| Previously, they would accept anything, but not behave appropriately. | ||
|
|
||
| * The web status no longer displays a potentially misleading message, indicating whether the build | ||
| can be rebuilt exactly. | ||
|
|
||
| * The ``SetProperty`` step in ``buildbot.steps.shell`` has been renamed to :bb:step:`SetPropertyFromCommand`. | ||
|
|
||
| Changes for Developers | ||
| ~~~~~~~~~~~~~~~~~~~~~~ | ||
|
|
||
| * Added an optional build start callback to ``buildbot.status.status_gerrit.GerritStatusPush`` | ||
|
|
||
| * An optional ``startCB`` callback to :bb:status:`GerritStatusPush` can be used | ||
| to send a message back to the committer. | ||
| See the linked documentation for details. | ||
|
|
||
| * bb:sched:`ChoiceStringParameter` has a new method ``getChoices`` that can be used to generate | ||
| content dynamically for Force scheduler forms. | ||
|
|
||
| Slave | ||
| ----- | ||
|
|
||
| Features | ||
| ~~~~~~~~ | ||
|
|
||
| * The fix for Twisted bug #5079 is now applied on the slave side, too. | ||
| This fixes a perspective broker memory leak in older versions of Twisted. | ||
| This fix was added on the master in Buildbot-0.8.4 (see :bb:bug:`1958`). | ||
|
|
||
| * The ``--nodaemon`` option to ``buildslave start`` now correctly prevents the slave from forking before running. | ||
|
