4.4.20. Release Notes for Buildbot v0.8.7¶
The following are the release notes for Buildbot v0.8.7. Buildbot v0.8.7 was released on September 22, 2012. Buildbot 0.8.7p1 was released on November 21, 2012.
4.4.20.1. 0.8.7p1¶
In addition to what's listed below, the 0.8.7p1 release adds the following.
- The
SetPropertiesFromEnv
step now correctly gets environment variables from the slave, rather than those set on the master. Also, it logs the changes made to properties. - The master-side
Git
source step now doesn't try to clone a branch calledHEAD
. This is whatgit
does by default, and specifying it explicitly doesn't work as expected. - The
Git
step properly deals with the case when there is a file calledFETCH_HEAD
in the checkout. - Buildbot no longer forks when told not to daemonize.
- Buildbot's startup is now more robust. See bug #1992.
- The
Trigger
step uses the provided list of source stamps exactly, if given, instead of adding them to the sourcestamps of the current build. In 0.8.7, they were combined with the source stamps for the current build. - The
Trigger
step again completely ignores the source stamp of the current build, ifalwaysUseLatest
is set. In 0.8.7, this was mistakenly changed to only ignore the specified revision of the source stamp. - The
Triggerable
scheduler is again properly passing changes through to the scheduled builds. See bug #2376. - Web change hooks log errors, allowing debugging.
- The
base
change hook now properly decodes the provided date. CVSMailDir
has been fixed.- Importing
buildbot.test
no longer causes python to exit, ifmock
insn't installed. The fixespydoc -k
when buildbot is installed. Mercurial
properly updates to the correct branch, when usinginrepo
branches.- Buildbot now doesn't fail on invalid UTF-8 in a number of places.
- Many documenation updates and fixes.
4.4.20.2. Master¶
Features¶
- Buildbot now supports building projects composed of multiple codebases. New
schedulers can aggregate changes to multiple codebases into source stamp sets
(with one source stamp for each codebase). Source steps then check out each
codebase as required, and the remainder of the build process proceeds
normally. See the Multiple-Codebase Builds for details.
- The format of the
got_revision
property has changed for multi-codebase builds. It is now a dictionary keyed by codebase.
- The format of the
Source
andShellCommand
steps now have an optionaldescriptionSuffix
, a suffix to thedescription
/descriptionDone
values. For example this can help distinguish between multipleCompile
steps that are applied to different codebases.- The
Git
step has a newgetDescription
option, which will rungit describe
after checkout normally. SeeGit
for details. - A new interpolation placeholder Interpolate, with more regular syntax, is available.
- A new ternary substitution operator
:?
and:#?
is available with theInterpolate
class. IRenderable.getRenderingFor
can now return a deferred.- The Mercurial hook now supports multiple masters. See pull request 436.
- There's a new poller for Mercurial:
HgPoller
. - The new
HTPasswdAprAuth
uses libaprutil (through ctypes) to validate the password against the hash from the .htpasswd file. This adds support for all hash types htpasswd can generate. GitPoller
has been rewritten. It now supports multiple branches and can share a directory between multiple pollers. It is also more resilient to changes in configuration, or in the underlying repository.- Added a new property
httpLoginUrl
tobuildbot.status.web.authz.Authz
to render a nice Login link in WebStatus for unauthenticated users ifuseHttpHeader
andhttpLoginUrl
are set. ForceScheduler
has been updated:- support for multiple codebases via the
codebases
parameter NestedParameter
to provide a logical grouping of parameters.CodebaseParameter
to set the branch/revision/repository/project for a codebase- new HTML/CSS customization points. Each parameter is contained in a
row
with multiple 'class' attributes associated with them (eg, 'force-string' and 'force-nested') as well as a unique id to use with Javascript. Explicit line-breaks have been removed from the HTML generator and are now controlled using CSS.
- support for multiple codebases via the
- The
SVNPoller
now supports multiple projects and codebases. See pull request 443. - The
MailNotifier
now takes a callable to calculate the "previous" build for purposes of determining status changes. See pull request 489. - The
copy_properties
parameter, given a list of properties to copy into the new build request, has been deprecated in favor of explicit use ofset_properties
.
Deprecations, Removals, and Non-Compatible Changes¶
Buildbot master now requires at least Python-2.5 and Twisted-9.0.0.
Passing a
BuildStep
subclass (rather than instance) toaddStep
is no longer supported. TheaddStep
method now takes exactly one argument.Buildbot master requires
python-dateutil
version 1.5 to support the Nightly scheduler.ForceScheduler
has been updated to support multiple codebases. The branch/revision/repository/project are deprecated; if you have customized these values, simply provide them ascodebases=[CodebaseParameter(name='', ...)]
.- The POST URL names for
AnyPropertyParameter
fields have changed. For example, 'property1name' is now 'property1_name', and 'property1value' is now 'property1_value'. Please update any bookmarked or saved URL's that used these fields. forcesched.BaseParameter
API has changed quite a bit and is no longer backwards compatible. Updating guidelines:get_from_post
is renamed togetFromKwargs
update_from_post
is renamed toupdateFromKwargs
. This function's parameters are now called via named parameters to allow subclasses to ignore values it doesnt use. Subclasses should add**unused
for future compatibility. A new parametersourcestampset
is provided to allow subclasses to modify the sourcestamp set, and will probably require you to add the**unused
field.
- The POST URL names for
The parameters to the callable version of
build.workdir
have changed. Instead of a single sourcestamp, a list of sourcestamps is passed. Each sourcestamp in the list has a different codebaseThe undocumented renderable
_ComputeRepositoryURL
is no longer imported tobuildbot.steps.source
. It is still available atbuildbot.steps.source.oldsource
.IProperties.render
now returns a deferred, so any code rendering properties by hand will need to take this into account.baseURL
has been removed inSVN
to use justrepourl
- see bug #2066. Branch info should be provided withInterpolate
.from buildbot.steps.source.svn import SVN factory.append(SVN(baseURL="svn://svn.example.org/svn/"))
can be replaced with
from buildbot.process.properties import Interpolate from buildbot.steps.source.svn import SVN factory.append(SVN(repourl=Interpolate("svn://svn.example.org/svn/%(src::branch)s")))
and
from buildbot.steps.source.svn import SVN factory.append(SVN(baseURL="svn://svn.example.org/svn/%%BRANCH%%/project"))
can be replaced with
from buildbot.process.properties import Interpolate from buildbot.steps.source.svn import SVN factory.append(SVN(repourl=Interpolate("svn://svn.example.org/svn/%(src::branch)s/project")))
and
from buildbot.steps.source.svn import SVN factory.append(SVN(baseURL="svn://svn.example.org/svn/", defaultBranch="branches/test"))
can be replaced with
from buildbot.process.properties import Interpolate from buildbot.steps.source.svn import SVN factory.append(SVN(repourl=Interpolate("svn://svn.example.org/svn/%(src::branch:-branches/test)s")))
The
P4Sync
step, deprecated since 0.8.5, has been removed. TheP4
step remains.The
fetch_spec
argument toGitPoller
is no longer supported.GitPoller
now only downloads branches that it is polling, so specifies a refspec itself.The format of the changes produced by
SVNPoller
has changed: directory pathnames end with a forward slash. This allows thesplit_file
function to distinguish between files and directories. Customized split functions may need to be adjusted accordingly.FlattenList has been deprecated in favor of Interpolate. Interpolate doesn't handle functions as keyword arguments. The following code using
WithProperties
from buildbot.process.properties import WithProperties def determine_foo(props): if props.hasProperty('bar'): return props['bar'] elif props.hasProperty('baz'): return props['baz'] return 'qux' WithProperties('%(foo)s', foo=determine_foo)
can be replaced with
from zope.interface import implementer from buildbot.interfaces import IRenderable from buildbot.process.properties import Interpolate @implementer(IRenderable) class determineFoo(object): def getRenderingFor(self, props): if props.hasProperty('bar'): return props['bar'] elif props.hasProperty('baz'): return props['baz'] return 'qux' Interpolate('%s(kw:foo)s', foo=determineFoo())
Changes for Developers¶
BuildStep.start
can now optionally return a deferred and any errback will be handled gracefully. If you useinlineCallbacks
, this means that unexpected exceptions and failures raised will be captured and logged and the build shut down normally.- The helper methods
getState
andsetState
fromBaseScheduler
have been factored intobuildbot.util.state.StateMixin
for use elsewhere.
