Buildbot Files

Bug fixes

• Improved handling of not found exceptions when stopping containers in Docker latent worker.
• Fixed garbage output from ANSI escape code sequences in build step logs (#7852)
• Fixed AuthorizedKeysManhole not picking up the specified ssh_host_keydir
• Fixed deprecation warnings being incorrectly raised as errors
• Fixed Git step failures when checking out commits containing LFS objects that require authentication
• Fixed crashes when using callable categories with HgPoller
• buildbot.reporters.http.HttpStatusPush now correctly exposes and passes through the skip_encoding parameter
• Implemented bold text style in build step logs (#7853)
• Websocket connections no longer allow unauthenticated users to connect when authorization is enabled

Changes

• Build now has a mutable env attribute, which is deep copied from the Builder's BuilderConfig.env. This allows steps to modify their current build's environment if needed.

Features

• Added a Build.do_build field and BuilderConfig.do_build_if to allow skipping entire builds
• Added support for configuring the database engine via the db.engine_kwargs configuration key
• Added support for tracking exact commits within codebases
• buildbot.util.httpclientservice.HTTPSession now supports mTLS. buildbot.reporters.http.HttpStatusPush now supports mTLS endpoints by accepting client certificates via the cert parameter (as either a combined file or tuple)
• Added a Log.flush() method to flush incomplete log lines without finishing the log
• Added a runtime_timeout argument to MasterShellCommand (#8377)
• Added a builds/<buildid>/triggered_builds Data API endpoint to retrieve builds triggered by a specific build

Misc

• Added a path_cls attribute (either PureWindowsPath or PurePosixPath depending on worker OS). This will replace path_module usage with better ergonomics and typing support.

Deprecations and Removals

• BuildFactory workdir callable support has been deprecated. Use renderables instead.
• Endpoint.pathPatterns as a multiline string has been deprecated. Use list of strings instead.
• ResourceType.eventPathPatterns as a multiline string has been deprecated. Use list of strings instead.
• DataConnector.produceEvent() has been deprecated. Use Data API update methods as replacement.
• The rootlinks Data and REST API endpoint has been deprecated
• Buildbot Master now requires Python 3.9 or newer. Python 3.8 is no longer supported.
• Raising NotImplementedError from reconfigServiceWithSibling or reconfigService has been deprecated. Use canReconfigWithSibling() that returns False as a replacement.
• buildbot.schedulers.base.BaseScheduler has been deprecated. Replace uses of it with ReconfigurableBaseScheduler.
• Old location of Dependent scheduler has been deprecated. Instead of buildbot.schedulers.basic.Dependent use buildbot.plugins.schedulers.Dependent.
