Buildbot

Bug fixes
---------

- Fix the umask parameter example to make it work with both Python 2.x and 3.x.
- Fix build-change association for multi-codebase builds in the console view..
- Fixed builders page doesn't list workers in multi-master configuration
(4326)
- Restricted groups added by :py:class:`~buildbot.www.oauth2.GitHubAuth`'s
``getTeamsMembership`` option to only those teams to which the user belongs.
Previously, groups were added for all teams for all organizations to which
the user belongs.
- Fix 'Show old workers' combo behavior.

Features
--------

- GitHub teams added to a user's ``groups`` by
:py:class:`~buildbot.www.oauth2.GitHubAuth`'s ``getTeamsMembership`` option
are now added by slug as well as by name. This means a team named "Bot
Builders" in the organization "buildbot" will be added as both ``buildbot/Bot
Builders`` and ``buildbot/bot-builders``.
- Make ``urlText`` renderable for the
:py:class:`~buildbot.steps.transfer.FileUpload` build step.
- Added ``noticeOnChannel`` option to :bb:reporter:`IRC` to send notices
instead of messages to channels. This was an option in v0.8.x and removed in
v0.9.0, which defaulted to sending notices. The v0.8.x default of sending
messages is now restored.

Reverts
-------

- Reverted: Fix git submodule support when using `sshPrivateKey` and `sshHostKey` because it broke other use cases (4316)
In order to have this feature to work, you need to keep your master in 1.4.0, and make sure your worker ``buildbot.tac`` are installed in the same path as your master.

Bug fixes
---------

- Fix `Build.getUrl()` to not ignore virtual builders.
- Fix git submodule support when using `sshPrivateKey` and `sshHostKey`
settings by passing ssh data as absolute, not relative paths.
- Fixed :bb:step:`P4` for change in latest version of `p4 login -p`.
- :py:class:`buildbot.reporters.irc.IrcStatusBot` no longer encodes messages
before passing them on to methods of its Twisted base class to avoid posting
the ``repr()`` of a bytes object when running on Python 3.

Features
--------

- Added new :bb:step:`GitPush` step to perform git push operations.
- Objects returned by :ref:`renderer` now are able to pass extra arguments to
the rendered function via `withArgs` method.

Test Suite
----------

- Test suite has been improved for readability by adding a lot of ``inlineCallbacks``
- Fixed tests which didn't wait for ``assertFailure``'s returned deferred.
- The test suite now runs on Python 3.7 (mostly deprecation warnings from dependencies shut down)

=====================================

Bug fixes
---------

- buildbot-worker docker image no longer use pidfile. This allows to
auto-restart a docker worker upon crash.
- GitLab v3 API is deprecated and has been removed from http://gitlab.com, so
we now use v4. (:issue:`4143`)

Features
--------

- -:bb:step:`Git` now supports `sshHostKey` parameter to specify ssh public
host key for fetch operations.
- -:bb:step:`Git` now supports `sshPrivateKey` parameter to specify private ssh
key for fetch operations.
- -:bb:chsrc:`GitPoller` now supports `sshHostKey` parameter to specify ssh
public host key for fetch operations. This feature is supported on git 2.3
and newer.
- -:bb:chsrc:`GitPoller` now supports `sshPrivateKey` parameter to specify
private ssh key for fetch operations. This feature is supported on git 2.3
and newer.
- Github hook token validation now uses ``hmac.compare_digest()`` for better security

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

- Removed support for GitLab v3 API ( GitLab < 9 ).

=====================================

Bug fixes
---------

- Fix issue which marked all workers dis-configured in the database every 24h
(:issue:`3981` :issue:`3956` :issue:`3970`)
- The :bb:reporter:`MailNotifier` no longer crashes when sending from/to email
addresses with "Real Name" parts (e.g., ``John Doe <john.doedomain.tld>``).
- Corrected pluralization of text on landing page of the web UI

Improved Documentation
----------------------

- Corrected typo in description of libvirt
- Update sample config to use preferred API

Misc Improvements
-----------------
