Buildbot

Bug fixes
---------

- Fix missing VERSION file in buildbot_worker wheel package (5948, 4464).
- Fixed error when attempting to specify ``ws_ping_interval`` configuration option (5991).

Bug fixes
---------

- Fixed usage of invalid characters in temporary file names by git-related steps (5949)
- Fixed parsing of URLs of the form https://api.bitbucket.org/2.0/repositories/OWNER/REPONAME in BitbucketStatusPush. These URLs are in the sourcestamps returned by the Bitbucket Cloud hook.
- 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.
- Improved cleanup of any containers left running by ``OpenstackLatentWorker``.
- Improved consistency of log messages produced by the reconfig script. Note that this output is not part of public API of Buildbot and may change at any time.
- Improved error message when try client cannot create a build due to builder being not configured on master side.
- Fixed exception when submitting builds via try jobdir client when the branch was not explicitly specified.
- Fixed handling of secrets in nested folders by the vault provider.

Features
--------

- Implemented report generator for new build requests
- Allow usage of Basic authentication to access GitHub API when looking for avatars
- Added support for default Pylint message that was changed in Pylint v2.0.
- Implemented support for configurable timeout in the reconfig script via new ``progress_timeout`` command-line parameter which determines how long it waits between subsequent progress updates in the logs before declaring a timeout.
- Implemented ``GitDiffInfo`` step that would extract information about what code has been changed in a pull/merge request.
- Add support ``--submodule`` option for the ``repo init`` command of the Repo source step.

Deprecations and Removals
-------------------------

- ``MessageFormatter`` will receive the actual builder name instead of ``whole buildset`` when used from ``BuildSetStatusGenerator``.

Bug fixes
---------

- Fixed a race condition in log handling of ``RpmLint`` and ``WarningCountingShellCommand`` steps resulting in steps crashing occasionally.
- Fixed incorrect state string of a finished buildstep being sent via message queue (5906).
- Reduced flickering of build summary tooltip during mouseover of build numbers (5930).
- Fixed missing data in Owners and Worker columns in changes and workers pages (5888, 5887).
- Fixed excessive debug logging in ``GerritEventLogPoller``.
- Fixed regression in pending buildrequests UI where owner is not displayed anymore (5940).
- Re-added support for ``lazylogfiles`` argument of ``ShellCommand`` that was available in old style steps.

Bug fixes
---------

- Updated Buildbot requirements to specify sqlalchemy 1.4 and newer as not supported yet.

Bug fixes
---------

- Fixed special character handling in avatar email URLs.
- Fixed errors when an email address matches GitHub commits but the user is unknown to it.
- Added missing report generators to the Buildbot plugin database (5892)
- Fixed non-default mode support for ``BuildSetStatusGenerator``.

Bug fixes
---------

- Avatar caching is now working properly and size argument is now handled correctly.
- Removed display of hidden steps in the build summary tooltip.
- ``GitHubPullrequestPoller`` now supports secrets in its ``token`` argument (4921)
- Plugin database will no longer issue warnings on load, but only when a particular entry is accessed.
- SSH connections are now run with ``-o BatchMode=yes`` to prevent interactive prompts which may tie up a step, reporter or change source until it times out.

Features
--------

- ``BitbucketPullrequestPoller``, ``BitbucketCloudEventHandler``, ``BitbucketServerEventHandler`` were enhanced to save PR entries matching provided masks as build properties.
- ``BitbucketPullrequestPoller`` has been enhanced to optionally authorize Bitbucket API.
- Added `pullrequesturl` property to the following pollers and change hooks: ``BitbucketPullrequestPoller``, ``GitHubPullrequestPoller``, ``GitHubEventHandler``.
This unifies all Bitbucket and GitHub pollers with the shared property interface.
- AvatarGitHub class has been enhanced to handle avatar based on email requests and take size argument into account
- Added support for Fossil user objects for use by the buildbot-fossil plugin.
- A new ``www.ws_ping_interval`` configuration option was added to avoid websocket timeouts when using reverse proxies and CDNs (4078)
