4. Release Notes
4.1. Buildbot 4.2.1 ( 2025-01-10 )
4.1.1. Bug fixes
- Fixed regression introduced in Buildbot 4.2.0 that broke support for renderable Git step repourl parameter. 
4.2. Buildbot 4.2.0 ( 2024-12-10 )
4.2.1. Bug fixes
- Fixed an Access is denied error on Windows when calling AssignProcessToJobObject (issue #8162). 
- Improved new build prioritization when many builds arrive at similar time. 
- Fixed - copydbscript when SQLAlchemy 2.x is used.
- Fixed - copydbscript when there are rebuilt builds in the database.
- Fixed - SetPropertiesFromEnvnot treating environment variable names as case insensitive for Windows workers
- Reliability of Gerrit change source has been improved on unstable connections. 
- Fixed bad default of Github webhooks not verifying HTTPS certificates in connections originating from Buildbot. 
- Fixed the timestamp comparison in janitor: it should cleanup builds ‘older than’ given timestamp - previously janitor would delete all build_data for builds ‘newer than’ the configured build data horizon. 
- Fixed compatibility with Twisted 24.11.0 due to - twisted.python.constantsmodule being moved.
- Fixed build status reporting to use state_string as fallback when - status_stringis- None. This makes IRC build failure messages more informative by showing the failure reason instead of just “failed”.
- Fix exception when worker loses connection to master while a command is running. 
- Fix certain combinations of ANSI reset escape sequences not displayed correctly (issue #8216). 
- Fixed wrong positioning of search box in Buildbot UI log viewer. 
- Improved ANSI escape sequence support in Buildbot UI log viewer: - Fixed support for formatting and color reset. - Fixed support for simultaneous background and foreground color (issue #8151). 
- Slightly reduced waterfall view loading times 
4.2.2. Improved Documentation
- Fixed Scheduler documentation to indicate that owner property is a string, not a list, and contains only one owner. This property was changed to singular and to string in Buildbot 1.0, but documentation was not updated. 
4.2.3. Features
- Use standard URL syntax for Git steps to enable the use of a dedicated SSH port. 
- Added - ignore-fk-error-rowsoption to- copy-dbscript. It allows ignoring all rows that fail foreign key constraint checks. This is useful in cases when migrating from a database engine that does not support foreign key constraints to one that does.
- Enhanced - debounce.methodto support calling target function only when the burst is finished.
- Added support for specifying the master protocol to - DockerLatentWorkerand- KubeLatentWorker. These classes get new- master_protocolargument. The worker docker image will receive the master protocol via BUILDMASTER_PROTOCOL environment variable.
- Master’s - cleanupdbcommand can now run database optimization on PostgreSQL and MySQL (only available on SQLite previously)
- Added a way to setup - TestReactorMixinwith explicit tear down function.
- Added a way to return all test result sets from getTestResultSets() and from data API via new /test_result_sets path. 
4.2.4. Misc
- Logs compression/decompression operation no longer occur in a Database connection thread. This change will improve overall master reactivity on instances receiving large logs from Steps. 
- Improve logs compression operation performance with zstd. Logs compression/decompression tasks now re-use - zstandard’s- ZstdCompressorand- ZstdDecompressorobjects, as advised in the documentation.
- BuildView’s ‘Changes’ tab (builders/:builderid/builds/:buildnumber) now only loads a limited number of changes, with the option to load more. 
- BuildView (builders/:builderid/builds/:buildnumber) now load ‘Changes’ and ‘Responsible Users’ on first access to the tab. This lower unnecessary queries on the master. 
4.2.5. Deprecations and Removals
- The following test tear down functions have been deprecated: - TestBuildStepMixin.tear_down_test_build_step()
- TestReactorMixin.tear_down_test_reactor()
 - The tear down is now run automatically. Any additional test tear down should be run using - twisted.trial.TestCase.addCleanupto better control tear down ordering.
- Worker.__init__no longer accepts- usePTYargument. It has been deprecated for a long time and no other values than- Nonewere accepted.
4.3. Buildbot 4.1.0 ( 2024-10-13 )
4.3.1. Bug fixes
- Fixed crash in - GerritEventLogPollerwhen invalid input is passed (issue #7612)
- Fixed - Buildsummary containing non obfuscated- Secretvalues present in a failed- BuildStepsummary (issue #7833)
- Fixed data API query using buildername to correctly work with buildername containing spaces and unicode characters (issue #7752) 
- Fixed an error when master is reconfigured with new builders and a build finishing at this time, causing the build to never finish. 
- Fixed crash on master shutdown trying to insubstantiate build’s worker when no worker is assigned to the build (issue #7753) 
- Fixed confusing error messages in case of HTTP errors that occur when connecting to Gerrit server. 
- Fixed - GitPollermerge commit processing.- GitPollernow correctly list merge commit files. (issue #7494)
- Fixed hang in - buildbot stop --cleanwhen a in progress build was waiting on a not yet started BuildRequest that it triggered.
- Improved error message in case of OAuth2 failures. 
- Fixed display of navigation links when the web frontend is displayed in narrow window (issue #7818) 
- Fixed inconsistent logs data in reports produced by report generators. In particular, - stepnamekey is consistently attached to logs regardless if they come with build steps or with the global- logskey.
- Fixed a regression where a - ChoiceStringParameterrequires a user selected value (no default value), but the force build form incorrectly displays the first choice as being selected which later causes validation error.
- Fixed logs - /rawand- /raw_inlineendpoint requiring large memory on master (more than full log size) (issue #3011)
- Fixed sidebar group expander to use different icon for expanded groups. 
- Log queries in BuildView ( - builders/:builderid/builds/:buildnumber) have been reduced when logs won’t be displayed to the user.
- REST API json responses now correctly provide the - Content-Lengthheader for non-HEAD requests.
- Buildbot is now compatible with SQLAlchemy v2.0+
