Buildbot Changelog

What's new in Buildbot 3.11.2

May 5, 2024
  • Bug fixes:
  • Fixed an error in HgPoller when repository initialization fails (#7488)
  • Updated Makefile to handle Windows paths and Python.
  • Added a web configuration setting to select whether build completion or start times are displayed.
  • Added revision info column in the web frontend.
  • Fixed steps raw log download button.
  • Fixed a regression in React UI that prevented hosting Buildbot at a custom URL prefix. This allows to support multiple Buildbot instances on a single server.
  • Improved Documentation:
  • Documented that ChangeSource does not support secrets (or any other renderables), best practice of not encoding secret values in changes and alternative solutions when secret values in changes are unavoidable. ChangeSource accidentally supported renderable arguments up until Buildbot 3.7, but this was not documented behavior.

New in Buildbot 3.11.1 (Mar 3, 2024)

  • Bug fixes:
  • GitPoller now ensures the SSH Private Key it uses has a trailing newline.
  • Migrated off python-future which prevented installing Buildbot on distributions that do not provide that package.
  • Fix sporadic navigation to builders page when new build is started

New in Buildbot 3.9.0 (Aug 27, 2023)

  • 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.

  • Fixed compatibility of hvac implementation with Vault 1.10.x
  • Fixed a race condition in PyLint step that may lead to step throwing exceptions.
  • Reporters now always wait for previous report to completing upload before sending another one. This works around a race condition in GitLab build reports ingestion pipeline
  • Fixed “retry fetch” and “clobber on failure” git checkout options.
  • Improved Visual Studio installation path retrieval when using MSBuild and only ‘BuildTools’ are installed.
  • Fixed search for Visual Studio executables by inspecting both C:Program Files and C:Program Files (x86) directories.
  • Fixed Visual Studio based steps causing an exception in getResultSummary when being skipped.
  • Fixed issue where workers would immediately retry login on authentication failure.
  • Fixed sending emails when using Twisted 21.2 or newer

New in Buildbot 3.5.0 (Mar 6, 2022)

  • Bug fixes:
  • Improved handling of "The container operating system does not match the host operating system" error on Docker on Windows to mark the build as erroneous so that it's not retried.

  • Fixed updating build step summary with mock state changes for MockBuildSRPM and MockRebuild.
  • Fixed support for optional builder parameter used in RebuildBuildEndpointMatcher (#6307).
  • Fixed error that caused builds to become stuck in building state until next master restart if builds that were in the process of being interrupted lost connection to the worker.
  • Fixed Gerrit change sources to emit changes with proper branch name instead of one containing refs/heads/ as the prefix.
  • Fixed handling of build_wait_timeout on latent workers which previously could result in latent worker being shut down while a build is running in certain scenarios (#5988).
  • Fixed problem on MySQL when using master names or builder tags that differ only by case.
  • Fixed timed schedulers not scheduling builds the first time they are enabled with onlyIfChanged=True when there are no important changes. In such case the state of the code is not known, so a build must be run to establish the baseline.
  • Switched Bitbucket OAuth client from the deprecated 'teams' APIs to the new 'workspaces' APIs
  • Fixed errors when killing a process on a worker fails due to any reason (e.g. permission error or process being already exited) (#6140).

  • Simplified :bb:cfg:prioritizeBuilders default function to make an example easier to customize.
  • Buildbot now exposes its internal framework for writing tests of custom build steps. Currently the API is experimental and subject to change.
  • Implemented detection of too long step and builder property names to produce errors at config time if possible.
  • Deprecations and Removals:
  • Deprecated subject argument of BuildStatusGenerator and BuildSetStatusGenerator status generators. Use subject argument of corresponding message formatters.

  • Fixed occasional InvalidSpotInstanceRequestID.NotFound errors when using spot instances on EC2. This could have lead to Buildbot launching zombie instances and not shutting them down.
  • Improved GitPoller behavior during reconfiguration to exit at earliest possible opportunity and thus reduce the delay that running GitPoller incurs for the reconfiguration.
  • The docker container for the master now fully builds the www packages. Previously they were downloaded from pypi which resulted in downloading whatever version was newest at the time (issue # 4998).
  • Implemented time out for master-side utility processes (e.g. git or hg) which could break the respective version control poller potentially indefinitely upon hanging.
  • Fixed a regression in the reconfig script which would time out instead of printing error when configuration update was not successfully applied.
  • Improved buildbot restart behavior to restore the worker paused state (issue # 6074)
  • Fixed support for binary patch files in try client (issue # 5933)

  • Brought back the old (pre v2.9.0) behavior of the FileDownload step to act more gracefully by returning FAILURE instead of raising an exception when the file doesn’t exist on master. This makes use cases such as FileDownload(haltOnFailure=False) possible again.
  • Fixed issue with getNewestCompleteTime which was returning no completed builds, although it could.
  • Fixed the Git source step causing last active branch to point to wrong commits. This only affected the branch state in the local repository, the checked out code was correct.
