  • Fixed excessive debug logging in GerritEventLogPoller.

  • Fixed regression in pending buildrequests UI where owner is not displayed anymore (issue # 5940).

  • Re-added support for lazylogfiles argument of ShellCommand that was available in old style steps.

5.2. Buildbot 2.10.4 ( 2021-03-16 )

  • Fixed build steps continuing running commands even if when they have been cancelled.

  • Worked around failure to build recent enough cryptography module in the docker image due to too old rust being available.

  • Fixed a regression in GitHubEventHandler in that it would require a GitHub token for public repositories (issue # 5760).

  • Fixed a regression in GerritChangeSource since v2.6.0 that caused only the first event related to a Gerrit change to be reporter as a change to Buildbot (issue # 5596). Now such deduplication will be applied only to patchset-created and ref-updated events.

  • Reconfiguration reliability has been improved by not reconfiguring WAMP router if settings have not changed.

  • Fixed unauthorized login errors when latent worker with automatic password is reconfigured during substantiation.

  • Fixed a crash when a manual step interruption is happening during master shutdown which tries to stop builds itself.

  • Fixed a race condition that may result in a deadlock if master is stopped at the same time a build is started.

  • Improved buildbot.util.poll.method to react faster to a request to stop. New pending calls are no longer executed. Calls whose interval but not random delay has already expired are no longer executed.

  • Fixed a crash when a trigger step is used in a build with patch body data passed via the try scheduler (issue # 5165).

  • Fixed secret replacement for an empty string or whitespace which may have many matches and generally will not need to be redacted.

  • Added the option to hide sensitive HTTP header values from the log in HTTPStep.

  • It is now possible to set urlText on a url linked to a MultipleFileUpload step.

  • Use os_auth_args to pass in authentication for OpenstackLatentWorker.

  • DebPbuilder, DebCowbuilder, UbuPbuilder and UbuCowbuilder now support renderables for the step parameters.

  • Added rules for Bitbucket to default revlink helpers.

  • Added counts of the statuses of the triggered builds to the summary of trigger steps

  • The worker preparation step now shows the worker name.

5.11.4. Deprecations and Removals

  • buildbot.test.fake.httpclientservice.HttpClientService.getFakeService() has been deprecated. Use getService method of the same class.

  • The MTR step has been deprecated due to migration to new style steps and the build result APIs. The lack of proper unit tests made it too time-consuming to migrate this step along with other steps. Contributors are welcome to step in, migrate this step and add a proper test suite so that this situation never happens again.

  • Many steps have been migrated to new style from old style.

    This only affects users who use steps as base classes for their own steps. New style steps provide a completely different set of functions that may be overridden. Direct instantiation of step classes is not affected. Old and new style steps work exactly the same in that case and users don’t need to do anything.

    The old-style steps have been deprecated since Buildbot v0.9.0 released in October 2016. The support for old-style steps will be removed entirely Buildbot v3.0.0 which will be released in near future. Users are advised to upgrade their custom steps to new-style steps as soon as possible.

    A gradual migration path is provided for steps that are likely to be used as base classes. Users need to inherit from <StepName>NewStyle class and convert all overridden APIs to use new-style step APIs. The old-style <StepName> classes will be provided until Buildbot v3.0.0 release. In Buildbot v3.0.0 <StepName> will refer to new-style steps and will be equivalent to <StepName>NewStyle. <StepName>NewStyle aliases will be removed in Buildbot v3.2.0.

    The list of old-style steps that have new-style equivalents for gradual migration is as follows:

    • Configure (new-style equivalent is ConfigureNewStyle)

    • Compile (new-style equivalent is CompileNewStyle)

    • HTTPStep (new-style equivalent is HTTPStepNewStyle)

    • GET, PUT, POST, DELETE, HEAD, OPTIONS (new-style equivalent is GETNewStyle, PUTNewStyle, POSTNewStyle, DELETENewStyle, HEADNewStyle, OPTIONSNewStyle)

    • MasterShellCommand (new-style equivalent is MasterShellCommandNewStyle)

    • ShellCommand (new-style equivalent is ShellCommandNewStyle)

    • SetPropertyFromCommand (new-style equivalent is SetPropertyFromCommandNewStyle)

    • WarningCountingShellCommand (new-style equivalent is WarningCountingShellCommandNewStyle)

    • Test (new-style equivalent is TestNewStyle)

    The list of old-style steps that have been converted to new style without a gradual migration path is as follows:

    • BuildEPYDoc

    • CopyDirectory

    • DebLintian

    • DebPbuilder

    • DirectoryUpload

    • FileDownload

    • FileExists

    • FileUpload

    • SetPropertiesFromEnv

    • Sphinx

    • StringDownload

    • TreeSize

    • Trial

    • VC6, VC7, VC8, VC9, VC10, VC11, VC12, VC14, VC141

    • VS2003, VS2005, VS2008, VS2010`, ``VS2012, VS2013, VS2015, VS2017

    Additionally, all source steps have been migrated to new style without a gradual migration path. Ability to be used as base classes was not documented and thus is considered unsupported. Please submit any custom steps to Buildbot for inclusion into the main tree to reduce maintenance burden. Additionally, bugs can be submitted to expose needed APIs publicly for which a migration path will be provided in the future.

    The list of old-style source steps that have been converted to new style is as follows:

    • Bzr

    • CVS

    • Darcs

    • Gerrit

    • Git

    • GitCommit

    • GitLab

    • GitPush

    • GitTag

    • Monotone

    • Mercurial

    • P4

    • Repo

    • Source

    • SVN

  • The undocumented and broken RpmSpec step has been removed.

  • The usage of certain parameters have been deprecated in BitbucketServerPRCommentPush, MailNotifier, PushjetNotifier and PushoverNotifier reporters. They have been replaced by the generators parameter. The support for the deprecated parameters will be removed in Buildbot v3.0. The list of deprecated parameters is as follows:

    • mode

    • tags

    • builders

    • buildSetSummary

    • messageFormatter

    • subject

    • addLogs

    • addPatch

    • schedulers

    • branches

    • watchedWorkers

    • messageFormatterMissingWorker

    The undocumented NotifierBase class has been renamed to ReporterBase.

    The undocumented HttpStatusPushBase class has been deprecated. Please use ReporterBase directly.

    The send method of the reporters based on HttpStatusPushBase has been deprecated. This affects only users who implemented custom reporters that directly or indirectly derive HttpStatusPushBase. Please use sendMessage as the replacement. The following reporters have been affected:

    • HttpStatusPush

    • BitbucketStatusPush

    • BitbucketServerStatusPush

    • BitbucketServerCoreAPIStatusPush

    • GerritVerifyStatusPush

    • GitHubStatusPush

    • GitLabStatusPush

    • HipChatStatusPush

    • ZulipStatusPush

  • BuildBot now requires SQLAlchemy 1.2.0 or newer.

Currently supported browsers are Chrome 56, Firefox 52, Edge 13 and Safari 10, newer versions of these browsers and their compatible derivatives. This set of browsers covers 98% of users of buildbot.net.

5.23. Buildbot 2.3.1 ( 2019-05-22 )

5.23.1. Bug fixes

5.24. Buildbot 2.3.0 ( 2019-05-06 )

5.24.1. Highlights

  • Support for older browsers has been hopefully temporarily broken due to frontend changes in progress. Notably, Internet Explorer 11 is not supported in this release. Currently supported browsers are Chrome 56, Firefox 52, Edge 13 and Safari 10, newer versions of these browsers and their compatible derivatives. This set of browsers covers 98% of users of buildbot.net.

5.24.2. Bug fixes

  • Fixed Git to clean the repository after the checkout when submodules are enabled. Previously this action could lead to untracked module directories after changing branches.

  • Latent workers with negative build_wait_timeout will be shutdown on master shutdown.

  • Latent worker will now wait until start_instance() before starting stop_instance() or vice-versa. Master will wait for these functions to finish during shutdown.

  • Latent worker will now correctly handle synchronous exception from the backend worker driver.

  • Fixed a potential error during database migration when upgrading to versions >=2.0 (issue # 4711).

5.24.3. Deprecations and Removals

  • The implementation language of the Buildbot web frontend has been changed from CoffeeScript to JavaScript. The documentation has not been updated yet, as we plan to transition to TypeScript. In the transitory period support for some browsers, notably IE 11 has been dropped. We hope to bring support for older browsers back once the transitory period is over.

  • The support for building Buildbot using npm as package manager has been removed. Please use yarn as a replacement that is used by Buildbot developers.

  • 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).

  • Removed support for Python <3.5 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.

  • 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 request 4536).

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

5.28.3. Features

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