Bug fixes

• Fixed an Access is denied error on Windows when calling AssignProcessToJobObject (#8162).
• Improved new build prioritization when many builds arrive at similar time.
• Fixed copydb script when SQLAlchemy 2.x is used.
• Fixed copydb script when there are rebuilt builds in the database.
• Fixed SetPropertiesFromEnv not 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.constants module being moved.
• Fixed build status reporting to use state_string as fallback when status_string is 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 (#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 (#8151).
• Slightly reduced waterfall view loading times

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.

Features

• Use standard URL syntax for Git steps to enable the use of a dedicated SSH port.
• Added ignore-fk-error-rows option to copy-db script. 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.method to support calling target function only when the burst is finished.
• Added support for specifying the master protocol to DockerLatentWorker and KubeLatentWorker. These classes get new master_protocol argument. The worker docker image will receive the master protocol via BUILDMASTER_PROTOCOL environment variable.
• Master's cleanupdb command can now run database optimization on PostgreSQL and MySQL (only available on SQLite previously)
• Added a way to setup TestReactorMixin with 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.

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 ZstdCompressor and ZstdDecompressor objects, 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.
