used in the tracker branch name.
5.5.2. Deprecations and Removals
The
pollinterval
(note the smalli
) argument of various change sources has been deprecated with a warning in favor ofpollInterval
.

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.
5.6.2. 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.
5.7. Buildbot 3.11.1
( 2024-02-24
)
5.7.1. 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.

)
5.8.1. Bug fixes
Declare Python 3.12 compatibility in generated packages of master and worker
5.8.2. Features
Added a new WSGI dashboards plugin for React frontend. It is backwards compatible with AngularJS one but may require changes in CSS styling of displayed web pages.
Implemented a report generator (
BuildSetCombinedStatusGenerator
) that can access complete information about a buildset.Low level database API now has
get_sourcestamps_for_buildset
to get source stamps for a buildset. “/buildsets/:buildsetid/sourcestamps” endpoint has been added to access this from the Data API.Added buildset information to dictionaries returned by report generators.
Added a way to pass additional reporter-specific data to Reporters. Added
extra_info_cb
argument toMessageFormatter
for this use case.Implemented support for report generators in
GerritStatusPush
.
5.8.3. Deprecations and Removals
The
reviewCB
,reviewArg
,startCB
,startArg
,summaryCB
,summaryArg
,builders
,wantSteps
,wantLogs
arguments ofGerritStatusPush
have been deprecated.
5.9. Buildbot 3.10.1
( 2023-12-26
)
5.9.1. Bug fixes
Fixed support for Twisted 23.10 and Python 3.12.
Fixed Data API to have “parent_buildid” key-value pair in messages for rebuilt buildsets (:issue 7222).
Improved security of tarfile extraction to help avoid CVE-2007-4559. See more details in https://peps.python.org/pep-0706/. Buildbot uses filter=’data’ now. (issue #7294)
Fixed web frontend package build on certain Python versions (e.g. 3.9).
5.10. Buildbot 3.10.0
( 2023-12-04
)
5.10.1. Bug fixes
buildbot.changes.bitbucket.BitbucketPullrequestPoller
has been updated to emit the change files.Fixed build status key sent to Bitbucket exceeding length limits (issue #7049).
Fixed a race condition resulting in
EXCEPTION
build results when build steps that are about to end are cancelled.Buildrequests are now selected by priority and then by buildrequestid (previously, Buildbot used the age as the secondary sort parameter). This preserves the property of choosing the oldest buildrequest, but makes it predictable which buildrequest will be selected, as there might be multiple buildrequests with the same age.
Fixed worker to fail a step
uploadDirectory
instead of throwing an exception when directory is not available. (issue #5878)Added missing
parent_buildid
andparent_relationship
keys to the buildset completion event in the Data API.Improved handling of Docker containers that fail before worker attaches to master. In such case build will be restarted immediately instead of waiting for a timeout to expire.
Enhanced the accessibility of secret files by enabling group-readability. Previously, secret files were exclusively accessible to the owner. Now, accessibility has been expanded to allow group members access as well. This enhancement is particularly beneficial when utilizing Systemd’s LoadCredential feature, which configures secrets with group-readable (0o440) permissions.
MailNotifier
now works correctly when SSL packages are installed butuseTls=False
and auth (smtpUser
,smtpPassword
) is not set. (issue #5609)P4 now reports the correct got_revision when syncing a changelist that only delete files
P4 step now use the rev-spec format //{p4client}/…@{revision} when syncing with a revision
Fixed incorrect propagation of option
--proxy-connection-string
into buildbot.tac when creating new Worker.Fixed link to Builder in React Grid View.
Addressed a number of timing errors in
Nightly
scheduler by upgradingcroniter
code.
5.10.2. Changes
Buildbot will render step properties and check if step should be skipped before acquiring locks. This allows to skip waiting for locks in case step is skipped.
The
isRaw
andisCollection
attributes of theEndpoint
type have been deprecated.Endpoint
is used to extend the Buildbot API. Us a replacement use the newkind
attribute.AbstractLatentWorker.check_instance()
now accepts error message being supplied in case instance is not good. The previous API has been deprecated.The published Docker image for the worker now uses Debian 11 (Bullseye) as base image.
The published Docker image for the worker now runs Buildbot in virtualenv.
5.10.3. Improved Documentation
Describe an existing bug with Libvirt latent workers that does not use a copy of the image (:issue 7122).
5.10.4. Features
The new React-based web frontend is no longer experimental. To enable please see the documentation on upgrading to 4.0 for more information. The new web frontend includes the following improvements compared to legacy AngularJS web frontend:
Project support (initially released in Buildbot 3.9.0).
Steps now show the amount of time spent waiting for locks.
The log viewer now supports huge logs without problems.
The log viewer now includes a search box that downloads entire log on-demand without additional button click.
The log viewer now supports downloading log file both as a file and also showing it inline in the browser.
The colors of the website can be adjusted from Buildbot configuration via
www["theme"]
key.Buildsteps and pending buildrequests have anchor links which allows linking directly to them from external web pages.
Workers can now be created to use
connection string
right out of the box when new option--connection-string=
is used.Docker Latent workers will now show last logs in Buildbot UI when their startup fails.
Added
EndpointKind.RAW_INLINE
data API endpoint type which will show the response data inline in the browser instead of downloading as a file.Implemented a way to specify volumes for containers spawned by
KubeLatentWorker
.Nightly
scheduler now supports forcing builds at specific times even ifonlyIfChanged
parameter was true and there were no important changes.buildbot.steps.source.p4.P4
can now take ap4client_type
argument to set the client type (More information on client type [here](https://www.perforce.com/manuals/p4sag/Content/P4SAG/performance.readonly.html))Added data and REST APIs to retrieve only projects with active builders.
Improved step result reporting to specify whether step failed due to a time out.
Added
tags
option to theGit
source step to download tags when updating repository.Worker now sends
failure_reason
update when the command it was running timed out.
5.10.5. Deprecations and Removals
Legacy AngularJS web frontend will be removed in Buildbot 4.0. Fixes to React web frontend that are regressions from AngularJS web frontend will be backported to 3.x Buildbot series to make migration easier.
Buildbot Master now requires Python 3.8 or newer. Python 3.7 is no longer supported.
buildbot.util.croniter
module has been deprecated in favor of using Pypicroniter
package.master.data.updates.setWorkerState()
has been deprecated. Usemaster.data.updates.set_worker_paused()
andmaster.data.updates.set_worker_graceful()
as replacements.Buildbot now requires
docker
of version v4.0.0 or newer for Docker support.BuildStep instances are now more strict about when their attributes can be changed. Changing attributes of BuildStep instances that are not yet part of any build is most likely an error. This is because such instances are only being used to configure a builder as a source to create real steps from. In this scenario any attribute changes are ignored as far as build configuration is concerned.
Such changing of attributes has been deprecated and will become an error in the future release.
For customizing BuildStep after an instance has already been created set_step_arg(name, value) function has been added.
5.11. Buildbot 3.9.2
( 2023-09-02
)
5.11.1. Bug fixes
Work around requirements parsing error for the Twisted dependency by pinning Twisted to 22.10 or older. This fixes buildbot crash on startup when newest Twisted is installed.
5.12. Buildbot 3.9.1
( 2023-09-02
)
5.12.1. Bug fixes
Fixed handling of primary key columns on Postgres in the
copy-db
script.Fixed a race condition in the
copy-db
script which sometimes lead to no data being copied.Options for create-worker that are converted to numbers are now also checked to be valid Python literals. This will prevent creating invalid worker configurations, e.g.: when using option
--umask=022
instead of--umask=0o022
or--umask=18
. (issue #7047)Fixed worker not connecting error when there are files in WORKER/info folder that can not be decoded. (issue #3585) (issue #4758) (issue #6932)
Fixed incorrect git command line parameters when using
Git
source step withmode="incremental"
,shallow=True
,submodules=True
(regression since Buildbot 3.9.0) (issue #7054).
5.12.2. Improved Documentation
Clarified that
shallow
option for theGit
source step is also supported inincremental
mode.
5.13. Buildbot 3.9.0
( 2023-08-16
)
5.13.1. 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 hasssh_server_alive_interval_s
andssh_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 (issue #6793).Fixed performance of changes data API queries with custom filters.
Prevent possible event loss during reconfig of reporters (issue #6982).
Fixed exception thrown when worker copies directories in Solaris operating system (issue #6870).
Fixed excessive log messages due to JWT token decoding error (issue #6872).
Fixed excessive log messages when otherwise unsupported
/auth/login
endpoint is accessed when usingRemoteUserAuth
authentication plugin.
5.13.2. 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 newproject
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 supportsBuildRequestGenerator
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 fromssh
process in case of connection failure.
5.13.3. Deprecations and Removals
Deprecated
projectName
andprojectURL
configuration dictionary keys.
5.14. Buildbot 3.8.0

Fixed compatibility issues with Python 3.11.
Fixed compatibility with Autobahn v22.4.1 and newer.
Fixed issue with overriding env when calling ShellMixin.makeRemoteShellCommand
Buildbot will now include the previous location of moved files when evaluating a Github commit. This fixes an issue where a commit that moves a file out of a folder, would not be shown in the web UI for a builder that is tracking that same folder.
Improved reliability of Buildbot log watching to follow log files even after rotation. This improves reliability of Buildbot start and restart scripts.
Fixed handling of occasional errors that happen when attempting to kill a master-side process that has already exited.
Fixed a race condition in PyLint step that may lead to step throwing exceptions.
Fixed compatibility with qemu 6.1 and newer when using LibVirtWorker with
cheap_copy=True
(default).Fixed an issue with secrets provider stripping newline from ssh keys sent in git steps.
Fixed occasional errors that happen when killing processes on Windows. TASKKILL command may return code 255 when process has already exited.
Fixed deleting secrets from worker that contain ‘~’ in their destination path.
5.14.2. Changes
Buildbot now requires NodeJS 14.18 or newer to build the frontend.
The URLs emitted by the Buildbot APIs have been changed to include slash after the hash (
#
) symbol to be compatible with what React web UI supports.
5.14.3. Improved Documentation
Replace statement “https is unsupported” with a more detailed disclaimer.
5.14.4. Features
Add a way to disable default
WarningCountingShellCommand
parser.Added health check API that latent workers can use to specify that a particular worker will not connect and build should not wait for it and mark itself as failure immediately.

property_<match_type>
parameters to perform filtering on change properties.
- Expanded
Exposed frontend configuration as implementation-defined JSON document that can be queried separately.
Added support for custom branch keys to
OldBuildCanceller
. This is useful in Version Control Systems such as Gerrit that have multiple branch names for the same logical branch that should be tracked by the canceller.p4port
argument of theP4
step has been marked renderable.Added automatic generation of commands for Telegram bot without need to send them manually to BotFather.
5.15.3. Deprecations and Removals
This release includes an experimental web UI written using React framework. The existing web UI is written using AngularJS framework which is no longer maintained. The new web UI can be tested by installing
buildbot-www-react
package and'base_react': {}
key-value to www plugins. Currently no web UI plugins are supported. The existing web UI will be deprecated on subsequent Buildbot released and eventually replaced with the React-based web UI on Buildbot 4.0.

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 rare
AlreadyCalledError
exceptions in the logs when worker worker connection is lost at the same time it is delivering final outcome of a command.Fixed errors when accessing non-existing build via REST API when an endpoint matching rule with builder filter was present.
Fixed an error in

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 (issue #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) (issue #6140).
Fixed updates to page title in the web UI. Web UI now shows the configured buildbot title within the page title.

GitPoller
behavior during reconfiguration to exit at earliest possible opportunity and thus reduce the delay that runningGitPoller
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
orhg
) 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)
Improved handling of unsubscription errors in WAMP which will no longer crash the unsubscribing component and instead just log an error.
Fixed a crash when a worker is disconnected from a running build that uses worker information for some of its properties (issue #5745).
5.22.2. Improved Documentation
Added documentation about installation Buildbot worker as Windows service.
5.22.3. Features
DebPbuilder
now supports the--othermirror
flag for including additional repositoriesImplemented support for setting docker container’s hostname
The libvirt latent worker will now wait for the VM to come online instead of disabling the worker during connection establishment process. The VM management connections are now pooled by URI.
Buildbot now sends metadata required to establish connection back to master to libvirt worker VMs.
LibVirtWorker
will now setup libvirt metadata with details needed by the worker to connect back to master.The docker container for the master has been switched to Debian. Additionally, buildbot is installed into a virtualenv there to reduce chances of conflicts with Python packages installed via
dpkg
.BitbucketStatusPush now has renderable build status key, name, and description.
Pausing a worker is a manual operation which the quarantine timer was overwriting. Worker paused state and quarantine state are now independent. (issue #5611)
Reduce buildbot_worker wheel package size by 40% by dropping tests from package.
5.22.4. Deprecations and Removals
The connection argument of the LibVirtWorker constructor has been deprecated along with the related Connection class. Use uri as replacement.
The
*NewStyle
build step aliases have been removed. Please use equivalent steps without theNewStyle
suffix in the name.Try client no longer supports protocol used by Buildbot older than v0.9.
5.23. Buildbot 3.1.1
( 2021-04-28
)
5.23.1. Bug fixes
Fix missing VERSION file in buildbot_worker wheel package (issue #5948, issue #4464).

Fixed usage of invalid characters in temporary file names by git-related steps (issue #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 returningFAILURE
instead of raising an exception when the file doesn’t exist on master. This makes use cases such asFileDownload(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.
5.24.2. 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 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 therepo init
command of the Repo source step.
5.24.3. Deprecations and Removals
MessageFormatter
will receive the actual builder name instead ofwhole buildset
when used fromBuildSetStatusGenerator
.

Reduced flickering of build summary tooltip during mouseover of build numbers (issue #5930).
Fixed missing data in Owners and Worker columns in changes and workers pages (issue #5888, issue #5887).
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 ofShellCommand
that was available in old style steps.

argument (issue #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.
5.28.2. Features
BitbucketPullrequestPoller
,BitbucketCloudEventHandler
