v2.1.0

Highlights

• Worker to Master protocol can now be encrypted via TLS.

Bug fixes

• To avoid database corruption, the upgrade-master command now ignores all
  signals except SIGKILL. It cannot be interrupted with ctrl-c
  (:issue:4600).
• Fixed incorrect tracking of latent worker states that could sometimes result
  in duplicate stop_instance calls and so on.
• Fixed a race condition that could manifest in cancelled substantiations if
  builds were created during insubstantiation of a latent worker.
• Perforce CLI Rev. 2018.2/1751184 (2019/01/21) is now supported
  (:issue:4574).
• Fix encoding issues with Forcescheduler parameters error management code.

Improved Documentation

• fix grammar mistakes and use Uppercase B for Buildbot

Features

• :py:class:~buildbot-worker.buildbot_worker.bot.Worker now have
  connection_string kw-argument which can be used to connect to a master
  over TLS.
• Adding 'expand_logs' option for LogPreview related settings.
• Force schedulers buttons are now sorted by their name. (:issue:4619)
• :bb:cfg:workers now have a new defaultProperties parameter.

v2.0.1

TAG 2.0.1

v2.0.0

Deprecations and Removals

• Removed support for Python 2.7 in the buildbot master code.
  Buildbot worker remains compatible with python2.7, and interoperability tests are run continuously.
• APIs that are not documented in the official Buildbot documentation have been
  made private. Users of these undocumented APIs are encouraged to file bugs to
  get them exposed.
• Removed support of old slave APIs from pre-0.9 days. Using old APIs may fail
  silently. To avoid weird errors when upgrading a Buildbot installation that
  may use old APIs, first upgrade to to 1.8.0 and make sure there are no
  deprecated API warnings.
• Remove deprecated default value handling of the keypair_name and
  security_name attributes of EC2LatentWorker.
• Support for Hyper.sh containers cloud provider has been removed as this
  service has shutdown.

Bug fixes

• Fix CRLF injection vulnerability with validating user provided redirect parameters (https://github.com/buildbot/buildbot/wiki/CRLF-injection-in-Buildbot-login-and-logout-redirect-code)
  Thanks to mik317 and mariadb for reporting it.

• Fix lockup during master shutdown when there's a build with unanswered ping
  from the worker and the TCP connection to worker is severed (issue:4575).

• Fix RemoteUserAuth.maybeAutLogin consumes bytes object as str leading to
  TypeError during JSON serialization. (:issue:4402)

• Various database integrity problems were fixed. Most notably, it is now
  possible to delete old changes without wiping all "child" changes in cascade
  (:issue:4539, :pull:4536).

• The GitLab change hook secret is now rendered correctly. (:issue:4118).

Features

• Identifiers can now contain UTF-8 characters which are not ASCII. This
  includes worker names, builder names, and step names.

v1.8.1

Bug fixes

• Fix CRLF injection vulnerability with validating user provided redirect parameters (https://github.com/buildbot/buildbot/wiki/CRLF-injection-in-Buildbot-login-and-logout-redirect-code)
  Thanks to mik317 and mariadb for reporting it.

v1.8.0

Bug fixes

• Fix a regression present in v1.7.0 which caused buildrequests waiting for a

• Don't run builds that request an instance with incompatible properties on
  Docker, Marathon and OpenStack latent workers.
• Gitpoller now fetches only branches that are known to exist on remote.
  Non-existing branches are quietly ignored.
• The demo repo in sample configuration files and the tutorial is now fetched
  via https: instead of git: to make life easier for those behind
  firewalls and/or using proxies.
• buildbot sendchange has been fixed on Python 3 (:issue:4138)

Features

• Add a :py:class:~buildbot.worker.kubernetes.KubeLatentWorker to launch
  workers into a kubernetes cluster
• Simplify/automate configuration of worker as Windows service - eliminate
  manual configuration of Log on as a service

Deprecations and Removals

  BuildMaster.data.updates.addBuildset instead.
• The deprecated BuildMaster.addChange method has been removed. Use
  BuildMaster.data.updates.addChange instead.
• buildbot package now requires Twisted versions >= 17.9.0. This is
  required for Python 3 support. Earlier versions of Twisted are not supported.

Bug fixes

• Fixed JSON decoding error when sending build properties to www change hooks

Features

• Added a page that lists all pending buildrequests (#4239)
• Builder page now has a plot displaying the evolution of build times over time

Features

• GitHub teams added to a user's groups by
  :py:class:~buildbot.www.oauth2.GitHubAuth's getTeamsMembership option

  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.

  v0.9.0, which defaulted to sending notices. The v0.8.x default of sending
  messages is now restored.

Reverts

• 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.

• Objects returned by :ref:renderer now are able to pass extra arguments to
  the rendered function via withArgs method.
