Bug fixes

  • Fixed missed invocations of methods decorated with util.debounce when debouncer was being stopped under certain conditions. This caused step and build state string updates to be sometimes missed.
  • Improved stale connection handling in GerritChangeSource. GerritChangeSource will instruct the ssh client to send periodic keepalive messages and will reconnect if the server does not reply for 45 seconds (default). GerritChangeSource now has ssh_server_alive_interval_s and ssh_server_alive_count_max options to control this behavior.
  • Fixed unnecessary build started under the following conditions: there is an existing Nightly scheduler, onlyIfChanged is set to true and there is version upgrade from v3.4.0 (#6793).
  • Fixed performance of changes data API queries with custom filters.
  • Prevent possible event loss during reconfig of reporters (#6982).
  • Fixed exception thrown when worker copies directories in Solaris operating system (#6870).
  • Fixed excessive log messages due to JWT token decoding error (#6872).
  • Fixed excessive log messages when otherwise unsupported /auth/login endpoint is accessed when using RemoteUserAuth authentication plugin.

Features

  • Introduce a way to group builders by project. A new projects list is added to the configuration dictionary. Builders can be associated to the entries in that list by the new project argument.

    Grouping builders by project allows to significantly clean up the UI in larger Buildbot installations that contain hundreds or thousands of builders for a smaller number of unrelated codebases. This is currently implemented only in experimental React UI.

  • Added support specifying the project in GitHubPullrequestPoller. Previously it was forced to be equal to GitHub's repository full name.

  • Reporter BitbucketServerCoreAPIStatusPush now supports BuildRequestGenerator and generates build status for build requests (by default).

  • Buildbot now has copy-db script migrate all data stored in the database from one database to another. This may be used to change database engine types. For example a sqlite database may be migrated to Postgres or MySQL when the load and data size grows.

  • Added cron features like last day of month to Nightly Scheduler.

  • Buildrequests can now have their priority changed, using the /buildrequests API.

  • The force scheduler can now set a build request priority.

  • Added support for specifying builder descriptions in markdown which is later rendered to HTML for presentation in the web frontend.

  • Build requests are now sorted according to their buildrequest. Request time is now used as a secondary sort key.

  • Significantly improved performance of reporters or reporters with slower generators which is important on larger Buildbot installations.

  • Schedulers can now set a default priority for the buildrequests that it creates. It can either be an integer or a function.

  • Implement support for shallow submodule update using git.

  • GerritChangeSource will now log a small number of previous log lines coming from ssh process in case of connection failure.

Deprecations and Removals

  • Deprecated projectName and projectURL configuration dictionary keys.
