|
|
* Release 0.7.7 (29 Mar 2008)
|
|
|
|
** Things You Need To Know
|
|
|
|
*** builder names must not start with an underscore (`_').
|
|
|
|
These are now reserved for internal buildbot purposes, such as the magic
|
|
"_all" pseudo-builder that the web pages use to allow force-build buttons
|
|
that start builds on all Builders at once.
|
|
|
|
** New Features
|
|
|
|
*** "buildbot checkconfig"
|
|
|
|
The "buildbot checkconfig" command will look at your master.cfg file and tell
|
|
you if there are any problems with it. This can be used to test potential
|
|
changes to your config file before submitting them to the running
|
|
buildmaster. This is particularly useful to run just before doing "buildbot
|
|
restart", since the restart will fail if the config file has an error. By
|
|
running "buildbot checkconfig master.cfg && buildbot restart", you'll only
|
|
perform the restart if the config file was ok. Many thanks to Ben Hearsum for
|
|
the patch.
|
|
|
|
*** Waterfall "?category=FOO" query-arguments
|
|
|
|
The Waterfall page now accepts one or more "category=" query arguments in the
|
|
URL, to filter the display by categories. These behave a lot like the
|
|
"builder=" query argument. Thanks to Jermo Davann for the patch.
|
|
|
|
** Bugs Fixed
|
|
|
|
Many bugs were fixed, and many minor features were added. Many thanks to
|
|
Dustin Mitchell who fixed and coordinated many of these. Here is a terse
|
|
list, for more details, please see the Trac page for the 0.7.7 release, at
|
|
http://buildbot.net/trac/query?status=closed&milestone=0.7.7 :
|
|
|
|
Many of the URLs generated by the buildbot were wrong.
|
|
Display of last-heard-from timestamps on the buildslaves web page were wrong.
|
|
Asking an IRC bot about a build waiting on a Lock should no longer crash.
|
|
Same for the web viewer.
|
|
Stop treating the encouraged info/ directory as leftover.
|
|
Add more force/stop build buttons.
|
|
Timestamps displayed on the waterfall now handle daylight savings properly.
|
|
p4poller no longer quits after a single failure.
|
|
Improved Git support, including 'try', branch, and revisions.
|
|
Buildslaves now use 'git', not 'cogito'.
|
|
Make older hg client/servers handle specific-revision builds properly.
|
|
Fix twisted.scripts._twistw problem on twisted-2.5.0 and windows.
|
|
Fix workdir= and env= on ShellCommands
|
|
Fix logfile-watching in 'buildbot start' on OS-X.
|
|
Fix ShellCommand crashes when the program emits >640kB of output per chunk.
|
|
New WarningCountingShellCommand step.
|
|
Fix TreeSize step.
|
|
Fix transfer.FileUpload/FileDownload crashes for large files.
|
|
Make 'buildbor reconfig' on windows tell you that it doesn't work.
|
|
Add a To: header to the mail sent by the slave-missing timeout.
|
|
Disable usePTY= for most unit tests, it makes some debian systems flunk tests.
|
|
Add 'absolute source stamps'
|
|
Add 'triggerable schedulers', and a buildstep to trigger them.
|
|
Remove buildbot.changes.freshcvsmail
|
|
Add new XMLRPC methods: getAllBuilders, getStatus, getLastBuilds.
|
|
Accept WithProperties in more places: env=, workdir=, others.
|
|
Use --no-auth-cache with SVN commands to avoid clobbering shared svn state.
|
|
Add hours/minutes/seconds in the waterfall's ETA display.
|
|
Trial: count Doctest lines too.
|
|
ShellCommand: record more info in the headers: stdin closing, PTY usage.
|
|
Make it possible to stop builds across reconfig boundaries.
|
|
SVN revision numbers are now passed as strings, which was breaking MailNotifier
|
|
|
|
** Deprecation Schedule
|
|
|
|
The changes.freshcvsmail change source was replaced by
|
|
changes.mail.FCMaildirSource in 0.7.6, and has been removed in 0.7.7 .
|
|
|
|
c['sources'] (plural) was replaced by c['change_source'] (singular) in 0.7.6,
|
|
and will be removed by 0.8.0.
|
|
|
|
c['bots'] was replaced by c['buildslaves'] in 0.7.6, and will be removed by
|
|
0.8.0 . c['bots'] only accepts BuildSlave instances, not name/passwd tuples.
|
|
|
|
The html.Waterfall status target was replaced by html.WebStatus in 0.7.6, and
|
|
will be removed by 0.8.0.
|
|
|
|
|
|
* Release 0.7.6 (30 Sep 2007)
|
|
|
|
** Things You Need To Know
|
|
|
|
*** 'buildbot upgrade-master'
|
|
|
|
Each time you install a new version of Buildbot, you should run the new
|
|
'buildbot upgrade-master' command on each of your pre-existing buildmasters.
|
|
This will add files and fix (or at least detect) incompatibilities between
|
|
your old config and the new code.
|
|
|
|
*** new WebStatus page
|
|
|
|
The Waterfall has been replaced by the more general WebStatus display,
|
|
described below. WebStatus serves static files from a new public_html/
|
|
directory that lives in the buildmaster's basedir. Files like index.html,
|
|
buildbot.css, and robots.txt are served directly from that directory, so any
|
|
modifications you wish to make should be made to those files. In particular,
|
|
any custom CSS you've written should be copied into public_html/buildbot.css.
|
|
The 'upgrade-master' command will populate this directory for you.
|
|
|
|
The old Waterfall page is deprecated, but it should continue to work for
|
|
another few releases. It is now a subclass of WebStatus which just replaces
|
|
the default root URL with another copy of the /waterfall resource.
|
|
|
|
*** Compatibility: Python-2.3 or newer, Twisted-2.0 or newer
|
|
|
|
No compatiblity losses here, buildbot-0.7.6 is compatible with the same
|
|
versions of python and twisted that 0.7.5 was.
|
|
|
|
Buildbot is tested on a regular basis (http://buildbot.buildbot.net) against
|
|
nearly a full matrix of Python-(2.3,2.4,2.5) * Twisted-(2.0,2.1,2.2,2.4,2.5).
|
|
|
|
*** New Buildbot Home Page
|
|
|
|
Buildbot has moved to a new Trac instance at http://buildbot.net/ , and all
|
|
new bugs and tickets should be filed there. The old sourceforge bugs at
|
|
http://buildbot.sf.net/ will slowly be migrated over. Mailing lists are still
|
|
managed at sourceforge, and downloads are still available there.
|
|
|
|
*** Changed/Deprecated master.cfg Keys and Classes
|
|
|
|
c['sources'] (plural) has been replaced by c['change_source'] (singular).
|
|
|
|
c['bots'] has been replaced by c['buildslaves'], and it expects a list of
|
|
BuildSlave instances instead of tuples. See below for more details.
|
|
|
|
The 'freshcvsmail' change source has been deprecated, and will be removed in
|
|
the next release.
|
|
|
|
The html.Waterfall status target has been deprecated, and replaced by
|
|
html.WebStatus .
|
|
|
|
** New Features
|
|
|
|
*** WebStatus
|
|
|
|
The new WebStatus display is a superset of the old Waterfall. It contains a
|
|
waterfall as a sub-page, but it also contains pages with more compact
|
|
representations of recent build status. The "one_line_per_build" page
|
|
contains just that, and "one_box_per_builder" shows just the information from
|
|
the top of the waterfall page (last-finished-build and current-activity).
|
|
|
|
The initial page (when you hit the root of the web site) is served from
|
|
index.html, and provides links to the Waterfall as well as the other pages.
|
|
|
|
Most of these pages can be filtered by adding query arguments to the URL.
|
|
Adding "?builder=XYZ" will cause the page to only show results for the given
|
|
builder. Adding "?builder=XYZ&builder=ABC" will show results for either
|
|
builder. "?branch=trunk" will limit the results to builds that involved code
|
|
from the trunk.
|
|
|
|
The /waterfall page has arguments to hide those annoying "buildslave
|
|
connected" messages, to start and and at arbitrary times, and to auto-refresh
|
|
at a chosen interval (with a hardcoded minimum of 15 seconds). It also has a
|
|
"help" page with forms that will help you add all of these nifty filtering
|
|
arguments.
|
|
|
|
The recommended practice is to modify the index.html file to include links to
|
|
the filtered pages that you find most useful.
|
|
|
|
Note that WebStatus defaults to allowForce=False, meaning that the display
|
|
will not offer or accept "Force Build" or "Stop Build" controls. (The old
|
|
Waterfall defaults to allowForce=True).
|
|
|
|
The new WebStatus pages try very hard to use only relative links, making life
|
|
better when the Buildbot sits behind an HTTP reverse proxy.
|
|
|
|
In addition, there is a rudimentary XMLRPC server run by the WebStatus
|
|
object. It only has two methods so far, but it will acquire more in the
|
|
future. The first customer of this is a project to add a buildbot plugin to
|
|
Trac.
|
|
|
|
*** BuildFactory.addStep(Step(args))
|
|
|
|
BuildFactories can be set up either with a complete list of steps, or by
|
|
calling the .addStep() method repeatedly. The preferred way to provide a step
|
|
is by instantiating it, rather than giving a class/kwargs pair. This gives
|
|
the BuildStep class a chance to examine the arguments (and complain about
|
|
anything it doesn't like) while the config file is being read and problems
|
|
are being logged. For example, the old-style:
|
|
|
|
from buildbot.process.factory import BuildFactory, s
|
|
steps = [s(CVS, cvsroot="blah", mode="copy"),
|
|
s(Compile, command=["make", "all"]),
|
|
s(Test, command=["make", "test"]),
|
|
]
|
|
f = BuildFactory(steps)
|
|
|
|
is now:
|
|
|
|
f = BuildFactory()
|
|
f.addStep( CVS(cvsroot="blah", mode="copy") )
|
|
f.addStep( Compile(command=["make", "all"]) )
|
|
f.addStep( Test(command=["make", "test"]) )
|
|
|
|
Authors of BuildStep subclasses which override __init__ to add new arguments
|
|
must register them with self.addFactoryArguments(**newargs) to make sure that
|
|
those classes will work with this new style, otherwise the new arguments will
|
|
be lost.
|
|
|
|
Using class/kwargs pairs is deprecated, and will be removed in a future
|
|
release.
|
|
|
|
|
|
*** BuildSlave instances, max_builds=, notify_on_missing=
|
|
|
|
Buildslave specification has changed a lot in this release. The old config:
|
|
|
|
c['bots'] = [ ("bot1name", "bot1passwd"),
|
|
("bot2name", "bot2passwd") ]
|
|
|
|
is now:
|
|
|
|
from buildbot.buildslave import BuildSlave
|
|
c['slaves'] = [ BuildSlave("bot1name", "bot1passwd"),
|
|
BuildSlave("bot2name", "bot2passwd") ]
|
|
|
|
This new form gives us the ability to add new controls. The first is
|
|
"max_builds=", which imposes a concurrency limit that is like the usual
|
|
SlaveLock, but gives the buildmaster the opportunity to find a different
|
|
slave to run the build. (the buildslave is chosen before the SlaveLock is
|
|
claimed, so pure SlaveLocks don't let you take full advantage of build
|
|
farms).
|
|
|
|
The other addition is "notify_on_missing=", which accepts an email address
|
|
(or list of addresses), and sends a message when the buildslave has been
|
|
disconnected for more than an hour (configurable with missing_timeout=). This
|
|
may be useful when you expect that the buildslave hosts should be available
|
|
most of the time, and want to investigate the reasons that it went offline.
|
|
|
|
|
|
** Other Improvements
|
|
|
|
The IRC bot has been refactored to make it easier to add instant-messaging
|
|
status delivery in the future. The IM plugins are not yet written, though.
|
|
|
|
When multiple buildslaves are available for a given build, one of them will
|
|
be picked at random. In previous releases, the first one on the list was
|
|
always picked. This helps to add a certain measure of load-balancing. More
|
|
improvements will be made in the future.
|
|
|
|
When the buildslave does a VC checkout step that requires clobbering the
|
|
build directory (i.e. in all modes except for 'update'), the buildslave will
|
|
first set the permissions on all build files to allow their deletion, before
|
|
it attempts to delete them. This should fix some problems in which a build
|
|
process left non-user-writable files lying around (frequently a result of
|
|
enthusiastic unit tests).
|
|
|
|
The BuildStep's workdir= argument can now accept a WithProperties()
|
|
specification, allowing greater control over the workdir.
|
|
|
|
Support for the 'Bazaar' version control system (/usr/bin/bzr) has been
|
|
added, using the buildbot.steps.source.Bzr class. This is a replacement for
|
|
the old 'Arch' (/usr/bin/tla and /usr/bin/baz) systems, which are still
|
|
supported by Buildbot with the source.Arch and source.Bazaar classes,
|
|
respectively. Unfortunately the old baz system claimed the 'Bazaar' classname
|
|
early, so the new system must use source.Bzr instead of the desired
|
|
source.Bazaar . A future release might change this.
|
|
|
|
A rudimentary Gnome Panel applet is provided in contrib/bb_applet.py, which
|
|
provides 'buildbot statusgui' -like colored status boxes inside the panel.
|
|
Installing it is a bit tricky, though.
|
|
|
|
The 'buildbot try' command now accepts a '--diff=foo.patch' argument, to let
|
|
you provide a pre-computed patch. This makes it easier to test out patches
|
|
that you've looked over for safety, without first applying them to your local
|
|
source tree.
|
|
|
|
A new Mercurial change source was added, hg_buildbot.py, which runs as an
|
|
in-process post-commit hook. This gives us access to much more information
|
|
about the change, as well as being much faster.
|
|
|
|
The email-based changesource have been refactored, to make it easier to write
|
|
new mail parsers. A parser for the SVN "commit-email.pl" script has been
|
|
added.
|
|
|
|
** Bugs Fixed
|
|
|
|
Far too many to count. Please see
|
|
http://buildbot.net/trac/query?status=closed&milestone=0.7.6 for a partial
|
|
list of tickets closed for this release, and the ChangeLog for a complete
|
|
list of all changes since 0.7.5 .
|
|
|
|
|
|
* Release 0.7.5 (10 Dec 2006)
|
|
|
|
** Things You Need To Know
|
|
|
|
*** The Great BuildStep Renaming
|
|
|
|
All BuildSteps have moved! They used to be classes in buildbot.process.step,
|
|
but now they all have separate modules in buildbot.steps.* . They have been
|
|
split out into separate categories: for example, the source checkout steps
|
|
are now buildbot.steps.source.CVS, buildbot.steps.source.Darcs, etc. The most
|
|
commonly used one is probably buildbot.steps.shell.ShellCommand . The
|
|
python-specific steps are in buildbot.steps.python, and the Twisted-specific
|
|
steps are in buildbot.steps.python_twisted .
|
|
|
|
You will need to update your master.cfg files to use the new names. The old
|
|
names are deprecated and will be removed altogether in the next release.
|
|
|
|
*** Compatibility
|
|
|
|
Buildbot now requires python-2.3 or later. Buildbot now requires
|
|
Twisted-2.0.0 or later. Support for earlier versions of both has finally been
|
|
removed. If you discover it works with unsupported versions, please return
|
|
your Buildbot to the factory for repairs :-).
|
|
|
|
Buildbot has *not* yet been tested against the recent python-2.5 release. It
|
|
has been tested against the latest SVN version of Twisted, but only in
|
|
conjunction with python-2.4 .
|
|
|
|
** new features
|
|
|
|
*** reconfiguring a Builder no longer causes a disconnect/reconnect cycle
|
|
|
|
This means that sending SIGHUP to the master or running 'buildbot reconfig
|
|
MASTERDIR' command no longer interrupts any current builds, nor does it lose
|
|
pending builds like it did before. This involved a fairly substantial
|
|
refactoring of the various internal BotPerspective/BotMaster/Builder classes.
|
|
Note that reconfiguring Schedulers still loses any Changes that were waiting
|
|
for the tree to become stable: hopefully this will be fixed in the next
|
|
release.
|
|
|
|
*** 'buildbot start/restart/reconfig' now show logs until startup is complete
|
|
|
|
These commands now have additional code to follow twistd.log and display all
|
|
the lines that are emitted from the beginning of the start/reconfig action
|
|
until it has completed. This gives you a chance to see any problems detected
|
|
in the config file without needing to manually look in twistd.log or use
|
|
another shell to 'tail -f' it. This also makes it clear which config file is
|
|
being used. This functionality is not available under windows.
|
|
|
|
In addition, if any problems are detected during 'start' or 'restart' (but
|
|
not reconfig), the buildbot command will terminate with a non-zero exit
|
|
status, making it easier to use in scripts. Closes SF#1517975.
|
|
|
|
*** Locks now take maxCount=N to allow multiple simultaneous owners
|
|
|
|
This allows Locks to be non-exclusive but still limit maximum concurrency.
|
|
Thanks to James Knight for the patch. Closes SF#1434997.
|
|
|
|
*** filetransfer steps
|
|
|
|
buildbot.steps.transfer.FileUpload is a buildstep that will move files from
|
|
the slave to the master. Likewise, FileDownload will move files from the
|
|
master down to the buildslave. Many thanks to Albert Hofkamp for contributing
|
|
these classes. Closes SF#1504631.
|
|
|
|
*** pyflakes step
|
|
|
|
buildbot.steps.python.PyFlakes will run the simple 'pyflakes' static analysis
|
|
tool and parse the results to tell you about undefined names, unused imports,
|
|
etc. You'll need to tell it how to run pyflakes, usually with something like
|
|
command=["pyflakes", "src/packagedir"] or the like. The default command is
|
|
"make pyflakes", which assumes that you have a suitable target in your
|
|
top-level Makefile.
|
|
|
|
*** Monotone support
|
|
|
|
Nathaniel Smith has contributed initial support for the Monotone version
|
|
control system. The code still needs docs and tests, but on the other hand it
|
|
has been in use by the Monotone buildbot for a long time now, so it is
|
|
probably fairly stable.
|
|
|
|
*** Tinderbox support
|
|
|
|
Ben Hearsum and the Mozilla crew have contributed some classes to allow
|
|
Buildbot to work with Tinderbox clients. One piece is
|
|
buildbot.changes.bonsaipoller.BonsaiPoller, which is a ChangeSource that
|
|
polls a Bonsai server (which is a kind of web-vased viewcvs CGI script) to
|
|
discover source code changes. The other piece is
|
|
buildbot.status.tinderbox.TinderboxMailNotifier, which is a status plugin
|
|
that sends email in the same format as Tinderbox does, which allows a number
|
|
of Tinderbox tools to be driven by Buildbot instead.
|
|
|
|
*** SVN Poller
|
|
|
|
Niklaus Giger contributed a ChangeSource (buildbot.changes.svnpoller) which
|
|
polls a remote SVN repository on a periodic basis. This is useful when, for
|
|
whatever reason, you cannot add a post-commit hook script to the repository.
|
|
This obsoletes the external contrib/svn_watcher.py script.
|
|
|
|
** notes for plugin developers
|
|
|
|
*** IStatusLog.readlines()
|
|
|
|
This new method makes it easier for a status plugin (or a
|
|
BuildStep.createSummary method) to walk through a StatusLog one line at a
|
|
time. For example, if you wanted to create an extra logfile that just
|
|
contained all the GCC warnings from the main log, you could use the
|
|
following:
|
|
|
|
def createSummary(self, log):
|
|
warnings = []
|
|
for line in log.readlines():
|
|
if "warning:" in line:
|
|
warnings.append()
|
|
self.addCompleteLog('warnings', "".join(warnings))
|
|
|
|
The "BuildStep LogFiles" section of the user's manual contains more
|
|
information. This method is not particularly memory-efficient yet (it reads
|
|
the whole logfile into memory first, then splits it into lines); this will be
|
|
improved in a future release.
|
|
|
|
** bug fixes
|
|
|
|
*** Update source.SVN to work with the new SVN-1.4.0
|
|
|
|
The latest subversion changed the behavior in an unusual situation which
|
|
caused the unit tests to fail. This was unlikely to cause a problem in actual
|
|
usage, but the tests have been updated to pass with the new version.
|
|
|
|
*** update svn_buildbot.py to avoid mangling filenames
|
|
|
|
Older versions of this script were stripping the wrong number of columns from
|
|
the output of 'svnlook changed', and would sometimes mangle filenames. This
|
|
has been fixed. Closes SF#1545146.
|
|
|
|
*** logfiles= caused subsequent build failures under Windows
|
|
|
|
Earlier versions of buildbot didn't explicitly close any logfiles= file
|
|
handles when the build finished. On windows (where you cannot delete a file
|
|
that someone else is reading), this could cause the next build to fail as the
|
|
source checkout step was unable to delete the old working directory. This has
|
|
been fixed. Closes SF#1568415.
|
|
|
|
*** logfiles= didn't work on OS-X
|
|
|
|
Macintosh OS-X has a different behavior when reading files that have reached
|
|
EOF, the result was that logfiles= sometimes didn't work. Thanks to Mark Rowe
|
|
for the patch.
|
|
|
|
** other changes
|
|
|
|
The 'buildbot sighup MASTERDIR' command has been replaced with 'buildbot
|
|
reconfig MASTERDIR', since that seems to be a slightly more meaningful name.
|
|
The 'sighup' form will remain as an alias.
|
|
|
|
|
|
* Release 0.7.4 (23 Aug 2006)
|
|
|
|
** Things You Need To Know
|
|
|
|
The PBChangeSource's prefix= argument has changed, you probably need to add a
|
|
slash now. This is mostly used by sites which use Subversion and
|
|
svn_buildbot.py.
|
|
|
|
The subcommands that are used to create a buildmaster or a buildslave have
|
|
changed. They used to be called 'buildbot master' and 'buildbot slave'. Now
|
|
they are called 'buildbot create-master' and 'buildbot create-slave'. Zipf's
|
|
Law suggests that these are more appropriate names for these
|
|
infrequently-used commands.
|
|
|
|
The syntax for the c['manhole'] feature has changed.
|
|
|
|
** new features
|
|
|
|
*** full Perforce support
|
|
|

SF#1473939: large patch from Scott Lamb, with docs and unit tests! This
|
|
includes both the step.P4 source-checkout BuildStep, and the changes.p4poller
|
|
ChangeSource you'll want to feed it. P4 is now supported just as well as all
|
|
the other VC systems. Thanks Scott!
|
|
|
|
*** SSH-based Manhole
|
|
|
|
The 'manhole' feature allows buildbot developers to get access to a python
|
|
read/eval/print loop (REPL) inside the buildmaster through a network
|
|
connection. Previously, this ran over unencrypted telnet, using a simple
|
|
username/password for access control. The new release defaults to encrypted
|
|
SSH access, using either username/password or an authorized_keys file (just
|
|
like sshd). There also exists an unencrypted telnet form, but its use is
|
|
discouraged. The syntax for setting up a manhole has changed, so master.cfg
|
|
files that use them must be updated. The "Debug options" section in the
|
|
user's manual provides a complete description.
|
|
|
|
*** Multiple Logfiles
|
|
|
|
BuildSteps can watch multiple log files in realtime, not just stdout/stderr.
|
|
This works in a similar fashion to 'tail -f': the file is polled once per
|
|
second, and any new data is sent to the buildmaster.
|
|
|
|
This requires a buildslave running 0.7.4 or later, and a warning message is
|
|
produced if used against an old buildslave (which will otherwise produce no
|
|
data). Use "logfiles={'name': 'filename'}" to take advantage of this feature
|
|
from master.cfg, and see the "ShellCommand" section of the user's manual for
|
|
full documentation.
|
|
|
|
The 'Trial' buildstep has been updated to use this, to display
|
|
_trial_temp/test.log in realtime. It also knows to fall back to the previous
|
|
"cat" command if the buildslave is too old.
|
|
|
|
*** BuildStep URLs
|
|
|
|
BuildSteps can now add arbitrary URLs which will be displayed on the
|
|
Waterfall page in the same place that Logs are presented. This is intended to
|
|
provide a link to generated HTML pages, such as the output of a code coverage
|
|
tool. The step is responsible for somehow uploading the HTML to a web server:
|
|
this feature merely provides an easy way to present the HREF link to the
|
|
user. See the "BuildStep URLs" section of the user's manual for details and
|
|
examples.
|
|
|
|
*** LogObservers
|
|
|
|
BuildSteps can now attach LogObservers to various logfiles, allowing them to
|
|
get real-time log output. They can use this to watch for progress-indicating
|
|
events (like counting the number of files compiled, or the number of tests
|
|
which have run), and update both ETA/progress-tracking and step text. This
|
|
allows for more accurate ETA information, and more information passed to the
|
|
user about how much of the process has completed.
|
|
|
|
The 'Trial' buildstep has been updated to use this for progress tracking, by
|
|
counting how many test cases have run.
|
|
|
|
** new documentation
|
|
|
|
What classes are useful in your master.cfg file? A table of them has been
|
|
added to the user's manual, in a section called "Index of Useful Classes".
|
|
|
|
Want a list of all the keys in master.cfg? Look in the "Index of master.cfg
|
|
keys" section.
|
|
|
|
A number of pretty diagrams have been added to the "System Architecture"
|
|
portion of the manual, explaining how all the buildbot pieces fit together.
|
|
|
|
An HTML form of the user's manual is now shipped in the source tarball. This
|
|
makes it a bit bigger: sorry about that. The old PyCon-2003 paper has been
|
|
removed from the distribution, as it is mostly supplanted by the user's
|
|
manual by this point.
|
|
|
|
** bugfixes
|
|
|
|
SF#1217699 + SF#1381867: The prefix= argument to PBChangeSource has been
|
|
changed: now it does just a simple string-prefix match and strip. The
|
|
previous behavior was buggy and unhelpful. NOTE: if you were using prefix=
|
|
before, you probably need to add a slash to the end of it.
|
|
|
|
SF#1398174: ignore SVN property changes better, fixed by Olivier Bonnet
|
|
|
|
SF#1452801: don't double-escape the build URL, fixed by Olivier Bonnet
|
|
|
|
SF#1401121: add support for running py2exe on windows, by Mark Hammond
|
|
|
|
reloading unchanged config files with WithProperties shouldn't change anything.
|
|
|
|
All svn commands now include --non-interactive so they won't ask for
|
|
passwords. Instead, the command will fail if it cannot be performed without
|
|
user input.
|
|
|
|
Deprecation warnings with newer versions of Twisted have been hushed.
|
|
|
|
** compatibility
|
|
|
|
I haven't actually removed support for Twisted-1.3.0 yet, but I'd like to.
|
|
|
|
The step_twisted default value for --reporter matches modern Twisteds,
|
|
though, and won't work under 1.3.0.
|
|
|
|
ShellCommand.flunkOnFailure now defaults to True, so any shell command which
|
|
fails counts as a build failure. Set this to False if you don't want this
|
|
behavior.
|
|
|
|
** minor features
|
|
|
|
contrib/darcs_buildbot.py contains a new script suitable for use in a darcs
|
|
commit-hook.
|
|
|
|
Hovering a cursor over the yellow "Build #123" box in the Waterfall display
|
|
will pop up an HTML tooltip to show the reason for the build. Thanks to Zandr
|
|
Milewski for the suggestion.
|
|
|
|
contrib/CSS/*.css now contains several contributed stylesheets to make the
|
|
Waterfall display a bit less ugly. Thanks to John O'Duinn for gathering them.
|
|
|
|
ShellCommand and its derivatives can now accept either a string or a list of
|
|
strings in the description= and descriptionDone= arguments. Thanks to Paul
|
|
Winkler for the catch.
|
|
|
|
|
|
* Release 0.7.3 (23 May 2006)
|
|
|
|
** compatibility
|
|
|
|
This release is compatible with Twisted-1.3.0, but the next one will not be.
|
|
Please upgrade to at least Twisted-2.0.x soon, as the next buildbot release
|
|
will require it.
|
|
|
|
** new features
|
|
|
|
*** Mercurial support
|
|
|
|
Support for Mercurial version control system (http://selenic.com/mercurial)
|
|
has been added. This adds a buildbot.process.step.Mercurial BuildStep. A
|
|
suitable hook script to deliver changes to the buildmaster is still missing.
|
|
|
|
*** 'buildbot restart' command
|
|
|
|
The 'buildbot restart BASEDIR' command will perform a 'buildbot stop' and
|
|
'buildbot start', and will attempt to wait for the buildbot process to shut
|
|
down in between. This is useful when you need to upgrade the code on your
|
|
buildmaster or buildslave and want to take it down for a minimum amount of
|
|
time.
|
|
|
|
*** build properties
|
|
|
|
Each build now has a set of named "Build Properties", which can be set by
|
|
steps and interpolated into ShellCommands. The 'revision' and 'got_revision'
|
|
properties are the most interesting ones available at this point, and can be
|
|
used e.g. to get the VC revision number into the filename of a generated
|
|
tarball. See the user's manual section entited "Build Properties" for more
|
|
details.
|
|
|
|
** minor features
|
|
|
|
*** IRC now takes password= argument
|
|
|
|
Useful for letting your bot claim a persistent identity.
|
|
|
|
*** svn_buildbot.py is easier to modify to understand branches
|
|
*** BuildFactory has a new .addStep method
|
|
*** p4poller has new arguments
|
|
*** new contrib scripts: viewcvspoll, svnpoller, svn_watcher
|
|
|
|
These poll an external VC repository to watch for changes, as opposed to
|
|
adding a hook script to the repository that pushes changes into the
|
|
buildmaster. This means higher latency but may be easier to configure,
|
|
especially if you do not have authority on the repository host.
|
|
|
|
*** VC build property 'got_revision'
|
|
|
|
The 'got_revision' property reports what revision a VC step actually
|
|
acquired, which may be useful to know when building from HEAD.
|
|
|
|
*** improved CSS in Waterfall
|
|
|
|
The Waterfall display has a few new class= tags, which may make it easier to
|
|
write custom CSS to make it look prettier.
|
|
|
|
*** robots_txt= argument in Waterfall
|
|
|
|
You can now pass a filename to the robots_txt= argument, which will be served
|
|
as the "robots.txt" file. This can be used to discourage search engine
|
|
spiders from crawling through the numerous build-status pages.
|
|
|
|
** bugfixes
|
|
|
|
*** tests more likely to pass on non-English systems
|
|
|
|
The unit test suite now sets $LANG='C' to make subcommands emit error
|
|
messages in english instead of whatever native language is in use on the
|
|
host. This improves the chances that the unit tests will pass on such
|
|
systems. This affects certain VC-related subcommands too.
|
|
|
|
test_vc was assuming that the system time was expressed with a numeric
|
|
timezone, which is not always the case, especially under windows. This
|
|
probably works better now than it did before. This only affects the CVS
|
|
tests.
|
|
|
|
'buildbot try' (for CVS) now uses UTC instead of the local timezone. The
|
|
'got_revision' property is also expressed in UTC. Both should help deal with
|
|
buggy versions of CVS that don't parse numeric timezones properly.
|
|
|
|
|
|
* Release 0.7.2 (17 Feb 2006)
|
|
|
|
** new features
|
|
|
|
*** all TCP port numbers in config file now accept a strports string
|
|
|
|
Sometimes it is useful to restrict certain TCP ports that the buildmaster
|
|
listens on to use specific network interfaces. In particular, if the
|
|
buildmaster and SVN repository live on the same machine, you may want to
|
|
restrict the PBChangeSource to only listen on the loopback interface,
|
|
insuring that no external entities can inject Changes into the buildbot.
|
|
Likewise, if you are using something like Apache's reverse-proxy feature to
|
|
provide access to the buildmaster's HTML status page, you might want to hide
|
|
the real Waterfall port by having it only bind to the loopback interface.
|
|
|
|
To accomplish this, use a string like "tcp:12345:interface=127.0.0.1" instead
|
|
of a number like 12345. These strings are called "strports specification
|
|
strings", and are documented in twisted's twisted.application.strports module
|
|
(you can probably type 'pydoc twisted.application.strports' to see this
|
|
documentation). Pretty much everywhere the buildbot takes a port number will
|
|
now accept a strports spec, and any bare numbers are translated into TCP port
|
|
numbers (listening on all network interfaces) for compatibility.
|
|
|
|
*** buildslave --umask control
|
|
|
|
Twisted's daemonization utility (/usr/bin/twistd) automatically sets the
|
|
umask to 077, which means that all files generated by both the buildmaster
|
|
and the buildslave will only be readable by the account under which the
|
|
respective daemon is running. This makes it unnecessarily difficult to share
|
|
build products (e.g. by symlinking ~/public_html/current_docs/ to a directory
|
|
within the slave's build directory where each build puts the results of a
|
|
"make docs" step).
|
|
|
|
The 'buildbot slave <PARAMS>' command now accepts a --umask argument, which
|
|
can be used to override the umask set by twistd. If you create the buildslave
|
|
with '--umask=022', then all build products will be world-readable, making it
|
|
easier for other processes (run under other accounts) to access them.
|
|
|
|
** bug fixes
|
|
|
|
The 0.7.1 release had a bug whereby reloading the config file could break all
|
|
configured Schedulers, causing them to raise an exception when new changes
|
|
arrived but not actually schedule a new build. This has been fixed.
|
|
|
|
Fixed a bug which caused the AnyBranchScheduler to explode when branch==None.
|
|
Thanks to Kevin Turner for the catch. I also think I fixed a bug whereby the
|
|
TryScheduler would explode when it was given a Change (which it is supposed
|
|
to simply ignore).
|
|
|
|
The Waterfall display now does more quoting of names (including Builder
|
|
names, BuildStep names, etc), so it is more likely that these names can
|
|
contain unusual characters like spaces, quotes, and slashes. There may still
|
|
be some problems with these kinds of names, however.. please report any bugs
|
|
to the mailing list.
|
|
|
|
|
|
* Release 0.7.1 (26 Nov 2005)
|
|
|
|
** new features
|
|
|
|
*** scheduler.Nightly
|
|
|
|
Dobes Vandermeer contributed a cron-style 'Nightly' scheduler. Unlike the
|
|
more-primitive Periodic class (which only lets you specify the duration
|
|
between build attempts), Nightly lets you schedule builds for specific times
|
|
of day, week, month, or year. The interface is very much like the crontab(5)
|
|
file. See the buildbot.scheduler.Nightly docstring for complete details.
|
|
|
|
** minor new features
|
|
|
|
*** step.Trial can work with Trial from Twisted >2.1.0
|
|
|
|
The 'Trial' step now accepts the trialMode= argument, which should be a list
|
|
of strings to be added to trial's argv array. This defaults to ["-to"], which
|
|
is appropriate for the Trial that ships in Twisted-2.1.0 and earlier, and
|
|
tells Trial to emit non-colorized verbose output. To use this step with
|
|
trials from later versions of Twisted, this should be changed to
|
|
["--reporter=bwverbose"].
|
|
|
|
In addition, you can now set other Trial command-line parameters through the
|
|
trialArgs= argument. This is a list of strings, and defaults to an empty list.
|
|
|
|
*** Added a 'resubmit this build' button to the web page
|
|
|
|
*** Make the VC-checkout step's description more useful
|
|
|
|
Added the word "[branch]" to the VC step's description (used in the Step's
|
|
box on the Waterfall page, among others) when we're checking out a
|
|
non-default branch. Also add "rNNN" where appropriate to indicate which
|
|
revision is being checked out. Thanks to Brad Hards and Nathaniel Smith for
|
|
the suggestion.
|
|
|
|
** bugs fixed
|
|
|
|
Several patches from Dobes Vandermeer: Escape the URLs in email, in case they
|
|
have spaces and such. Fill otherwise-empty <td> elements, as a workaround for
|
|
buggy browsers that might optimize them away. Also use binary mode when
|
|
opening status pickle files, to make windows work better. The
|
|
AnyBranchScheduler now works even when you don't provide a fileIsImportant=
|
|
argument.
|
|
|
|
Stringify the base revision before stuffing it into a 'try' jobfile, helping
|
|
SVN and Arch implement 'try' builds better. Thanks to Steven Walter for the
|
|
patch.
|
|
|
|
Fix the compare_attrs list in PBChangeSource, FreshCVSSource, and Waterfall.
|
|
Before this, certain changes to these objects in the master.cfg file were
|
|
ignored, such that you would have to stop and re-start the buildmaster to
|
|
make them take effect.
|
|
|
|
The config file is now loaded serially, shutting down old (or replaced)
|
|
Status/ChangeSource plugins before starting new ones. This fixes a bug in
|
|
which changing an aspect of, say, the Waterfall display would cause an
|
|
exception as both old and new instances fight over the same TCP port. This
|
|
should also fix a bug whereby new Periodic Schedulers could fire a build
|
|
before the Builders have finished being added.
|
|
|
|
There was a bug in the way Locks were handled when the config file was
|
|
reloaded: changing one Builder (but not the others) and reloading master.cfg
|
|
would result in multiple instances of the same Lock object, so the Locks
|
|
would fail to prevent simultaneous execution of Builds or Steps. This has
|
|
been fixed.
|
|
|
|
** other changes
|
|
|
|
For a long time, certain StatusReceiver methods (like buildStarted and
|
|
stepStarted) have been able to return another StatusReceiver instance
|
|
(usually 'self') to indicate that they wish to subscribe to events within the
|
|
new object. For example, if the buildStarted() method returns 'self', the
|
|
status receiver will also receive events for the new build, like
|
|
stepStarted() and buildETAUpdate(). Returning a 'self' from buildStarted() is
|
|
equivalent to calling build.subscribe(self).
|
|
|
|
Starting with buildbot-0.7.1, this auto-subscribe convenience will also
|
|
register to automatically unsubscribe the target when the build or step has
|
|
finished, just as if build.unsubscribe(self) had been called. Also, the
|
|
unsubscribe() method has been changed to not explode if the same receiver is
|
|
unsubscribed multiple times. (note that it will still explode is the same
|
|
receiver is *subscribed* multiple times, so please continue to refrain from
|
|
doing that).
|
|
|
|
|
|
* Release 0.7.0 (24 Oct 2005)
|
|
|
|
** new features
|
|
|
|
*** new c['schedulers'] config-file element (REQUIRED)
|
|
|
|
The code which decides exactly *when* a build is performed has been massively
|
|
refactored, enabling much more flexible build scheduling. YOU MUST UPDATE
|
|
your master.cfg files to match: in general this will merely require you to
|
|
add an appropriate c['schedulers'] entry. Any old ".treeStableTime" settings
|
|
on the BuildFactory instances will now be ignored. The user's manual has
|
|
complete details with examples of how the new Scheduler classes work.
|
|
|
|
*** c['interlocks'] removed, Locks and Dependencies now separate items
|
|
|
|
The c['interlocks'] config element has been removed, and its functionality
|
|
replaced with two separate objects. Locks are used to tell the buildmaster
|
|
that certain Steps or Builds should not run at the same time as other Steps
|
|
or Builds (useful for test suites that require exclusive access to some
|
|
external resource: of course the real fix is to fix the tests, because
|
|
otherwise your developers will be suffering from the same limitations). The
|
|
Lock object is created in the config file and then referenced by a Step
|
|
specification tuple or by the 'locks' key of the Builder specification
|
|
dictionary. Locks come in two flavors: MasterLocks are buildmaster-wide,
|
|
while SlaveLocks are specific to a single buildslave.
|
|
|
|
When you want to have one Build run or not run depending upon whether some
|
|
other set of Builds have passed or failed, you use a special kind of
|
|
Scheduler defined in the scheduler.Dependent class. This scheduler watches an
|
|
upstream Scheduler for builds of a given source version to complete, and only
|
|
fires off its own Builders when all of the upstream's Builders have built
|
|
that version successfully.
|
|
|
|
Both features are fully documented in the user's manual.
|
|
|
|
*** 'buildbot try'
|
|
|
|
The 'try' feature has finally been added. There is some configuration
|
|
involved, both in the buildmaster config and on the developer's side, but
|
|
once in place this allows the developer to type 'buildbot try' in their
|
|
locally-modified tree and to be given a report of what would happen if their
|
|
changes were to be committed. This works by computing a (base revision,
|
|
patch) tuple that describes the developer's tree, sending that to the
|
|
buildmaster, then running a build with that source on a given set of
|
|
Builders. The 'buildbot try' tool then emits status messages until the builds
|
|
have finished.
|
|
|
|
'try' exists to allow developers to run cross-platform tests on their code
|
|
before committing it, reducing the chances they will inconvenience other
|
|
developers by breaking the build. The UI is still clunky, but expect it to
|
|
change and improve over the next few releases.
|
|
|
|
Instructions for developers who want to use 'try' (and the configuration
|
|
changes necessary to enable its use) are in the user's manual.
|
|
|
|
*** Build-On-Branch
|
|
|
|
When suitably configured, the buildbot can be used to build trees from a
|
|
variety of related branches. You can set up Schedulers to build a tree using
|
|
whichever branch was last changed, or users can request builds of specific
|
|
branches through IRC, the web page, or (eventually) the CLI 'buildbot force'
|
|
subcommand.
|
|
|
|
The IRC 'force' command now takes --branch and --revision arguments (not that
|
|
they always make sense). Likewise the HTML 'force build' button now has an
|
|
input field for branch and revision. Your build's source-checkout step must
|
|
be suitably configured to support this: for SVN it involves giving both a
|
|
base URL and a default branch. Other VC systems are configured differently.
|
|
The ChangeSource must also provide branch information: the 'buildbot
|
|
sendchange' command now takes a --branch argument to help hook script writers
|
|
accomplish this.
|
|
|
|
*** Multiple slaves per Builder
|
|
|
|
You can now attach multiple buildslaves to each Builder. This can provide
|
|
redundancy or primitive load-balancing among many machines equally capable of
|
|
running the build. To use this, define a key in the Builder specification
|
|
dictionary named 'slavenames' with a list of buildslave names (instead of the
|
|
usual 'slavename' that contains just a single slavename).
|
|
|
|
*** minor new features
|
|
|
|
The IRC and email status-reporting facilities now provide more specific URLs
|
|
for particular builds, in addition to the generic buildmaster home page. The
|
|
HTML per-build page now has more information.
|
|
|
|
The Twisted-specific test classes have been modified to match the argument
|
|
syntax preferred by Trial as of Twisted-2.1.0 and newer. The generic trial
|
|
steps are still suitable for the Trial that comes with older versions of
|
|
Twisted, but may produce deprecation warnings or errors when used with the
|
|
latest Trial.
|
|
|
|
** bugs fixed
|
|
|
|
DNotify, used by the maildir-watching ChangeSources, had problems on some
|
|
64-bit systems relating to signed-vs-unsigned constants and the DN_MULTISHOT
|
|
flag. A workaround was provided by Brad Hards.
|
|
|
|
The web status page should now be valid XHTML, thanks to a patch by Brad
|
|
Hards. The charset parameter is specified to be UTF-8, so VC comments,
|
|
builder names, etc, should probably all be in UTF-8 to be displayed properly.
|
|
|
|
** creeping version dependencies
|
|
|
|
The IRC 'force build' command now requires python2.3 (for the shlex.split
|
|
function).
|
|
|
|
|
|
* Release 0.6.6 (23 May 2005)
|
|
|
|
** bugs fixed
|
|
|
|
The 'sendchange', 'stop', and 'sighup' subcommands were broken, simple bugs
|
|
that were not caught by the test suite. Sorry.
|
|
|
|
The 'buildbot master' command now uses "raw" strings to create .tac files
|
|
that will still function under windows (since we must put directory names
|
|
that contain backslashes into that file).
|
|
|
|
The keep-on-disk behavior added in 0.6.5 included the ability to upgrade old
|
|
in-pickle LogFile instances. This upgrade function was not added to the
|
|
HTMLLogFile class, so an exception would be raised when attempting to load or
|
|
display any build with one of these logs (which are normally used only for
|
|
showing build exceptions). This has been fixed.
|
|
|
|
Several unnecessary imports were removed, so the Buildbot should function
|
|
normally with just Twisted-2.0.0's "Core" module installed. (of course you
|
|
will need TwistedWeb, TwistedWords, and/or TwistedMail if you use status
|
|
targets that require them). The test suite should skip all tests that cannot
|
|
be run because of missing Twisted modules.
|
|
|
|
The master/slave's basedir is now prepended to sys.path before starting the
|
|
daemon. This used to happen implicitly (as a result of twistd's setup
|
|
preamble), but 0.6.5 internalized the invocation of twistd and did not copy
|
|
this behavior. This change restores the ability to access "private.py"-style
|
|
modules in the basedir from the master.cfg file with a simple "import
|
|
private" statement. Thanks to Thomas Vander Stichele for the catch.
|
|
|
|
|
|
* Release 0.6.5 (18 May 2005)
|
|
|
|
** deprecated config keys removed
|
|
|
|
The 'webPortnum', 'webPathname', 'irc', and 'manholePort' config-file keys,
|
|
which were deprecated in the previous release, have now been removed. In
|
|
addition, Builders must now always be configured with dictionaries: the
|
|
support for configuring them with tuples has been removed.
|
|
|
|
** master/slave creation and startup changed
|
|
|
|
The buildbot no longer uses .tap files to store serialized representations of
|
|
the buildmaster/buildslave applications. Instead, this release now uses .tac
|
|
files, which are human-readable scripts that create new instances (rather
|
|
than .tap files, which were pickles of pre-created instances). 'mktap
|
|
buildbot' is gone.
|
|
|
|
You will need to update your buildbot directories to handle this. The
|
|
procedure is the same as creating a new buildmaster or buildslave: use
|
|
'buildbot master BASEDIR' or 'buildbot slave BASEDIR ARGS..'. This will
|
|
create a 'buildbot.tac' file in the target directory. The 'buildbot start
|
|
BASEDIR' will use twistd to start the application.
|
|
|
|
The 'buildbot start' command now looks for a Makefile.buildbot, and if it
|
|
finds one (and /usr/bin/make exists), it will use it to start the application
|
|
instead of calling twistd directly. This allows you to customize startup,
|
|
perhaps by adding environment variables. The setup commands create a sample
|
|
file in Makefile.sample, but you must copy this to Makefile.buildbot to
|
|
actually use it. The previous release looked for a bare 'Makefile', and also
|
|
installed a 'Makefile', so you were always using the customized approach,
|
|
even if you didn't ask for it. That old Makefile launched the .tap file, so
|
|
changing names was also necessary to make sure that the new 'buildbot start'
|
|
doesn't try to run the old .tap file.
|
|
|
|
'buildbot stop' now uses os.kill instead of spawning an external process,
|
|
making it more likely to work under windows. It waits up to 5 seconds for the
|
|
daemon to go away, so you can now do 'buildbot stop BASEDIR; buildbot start
|
|
BASEDIR' with less risk of launching the new daemon before the old one has
|
|
fully shut down. Likewise, 'buildbot start' imports twistd's internals
|
|
directly instead of spawning an external copy, so it should work better under
|
|
windows.
|
|
|
|
** new documentation
|
|
|
|
All of the old Lore-based documents were converted into a new Texinfo-format
|
|
manual, and considerable new text was added to describe the installation
|
|
process. The docs are not yet complete, but they're slowly shaping up to form
|
|
a proper user's manual.
|
|
|
|
** new features
|
|
|
|
Arch checkouts can now use precise revision stamps instead of always using
|
|
the latest revision. A separate Source step for using Bazaar (an alternative
|
|
Arch client) instead of 'tla' was added. A Source step for Cogito (the new
|
|
linux kernel VC system) was contributed by Brandon Philips. All Source steps
|
|
now accept a retry= argument to indicate that failing VC checkouts should be
|
|
retried a few times (SF#1200395), note that this requires an updated
|
|
buildslave.
|
|
|
|
The 'buildbot sendchange' command was added, to be used in VC hook scripts to
|
|
send changes at a pb.PBChangeSource . contrib/arch_buildbot.py was added to
|
|
use this tool; it should be installed using the 'Arch meta hook' scheme.
|
|
|
|
Changes can now accept a branch= parameter, and Builders have an
|
|
isBranchImportant() test that acts like isFileImportant(). Thanks to Thomas
|
|
Vander Stichele. Note: I renamed his tag= to branch=, in anticipation of an
|
|
upcoming feature to build specific branches. "tag" seemed too CVS-centric.
|
|
|
|
LogFiles have been rewritten to stream the incoming data directly to disk
|
|
rather than keeping a copy in memory all the time (SF#1200392). This
|
|
drastically reduces the buildmaster's memory requirements and makes 100MB+
|
|
log files feasible. The log files are stored next to the serialized Builds,
|
|
in files like BASEDIR/builder-dir/12-log-compile-output, so you'll want a
|
|
cron job to delete old ones just like you do with old Builds. Old-style
|
|
Builds from 0.6.4 and earlier are converted when they are first read, so the
|
|
first load of the Waterfall display after updating to this release may take
|
|
quite some time.
|
|
|
|
** build process updates
|
|
|
|
BuildSteps can now return a status of EXCEPTION, which terminates the build
|
|
right away. This allows exceptions to be caught right away, but still make
|
|
sure the build stops quickly.
|
|
|
|
** bug fixes
|
|
|
|
Some more windows incompatibilities were fixed. The test suite now has two
|
|
failing tests remaining, both of which appear to be Twisted issues that
|
|
should not affect normal operation.
|
|
|
|
The test suite no longer raises any deprecation warnings when run against
|
|
twisted-2.0 (except for the ones which come from Twisted itself).
|
|
|
|
|
|
* Release 0.6.4 (28 Apr 2005)
|
|
|
|
** major bugs fixed
|
|
|
|
The 'buildbot' tool in 0.6.3, when used to create a new buildmaster, failed
|
|
unless it found a 'changes.pck' file. As this file is created by a running
|
|
buildmaster, this made 0.6.3 completely unusable for first-time
|
|
installations. This has been fixed.
|
|
|
|
** minor bugs fixed
|
|
|
|
The IRC bot had a bug wherein asking it to watch a certain builder (the "I'll
|
|
give a shout when the build finishes" message) would cause an exception, so
|
|
it would not, in fact, shout. The HTML page had an exception in the "change
|
|
sources" page (reached by following the "Changes" link at the top of the
|
|
column that shows the names of commiters). Re-loading the config file while
|
|
builders were already attached would result in a benign error message. The
|
|
server side of the PBListener status client had an exception when providing
|
|
information about a non-existent Build (e.g., when the client asks for the
|
|
Build that is currently running, and the server says "None").
|
|
|
|
These bugs have all been fixed.
|
|
|
|
The unit tests now pass under python2.2; they were failing before because of
|
|
some 2.3isms that crept in. More unit tests which failed under windows now
|
|
pass, only one (test_webPathname_port) is still failing.
|
|
|
|
** 'buildbot' tool looks for a .buildbot/options file
|
|
|
|
The 'statusgui' and the 'debugclient' subcommands can both look for a
|
|
.buildbot/ directory, and an 'options' file therein, to extract default
|
|
values for the location of the buildmaster. This directory is searched in the
|
|
current directory, its parent, etc, all the way up to the filesystem root
|
|
(assuming you own the directories in question). It also look in ~/.buildbot/
|
|
for this file. This feature allows you to put a .buildbot at the top of your
|
|
working tree, telling any 'buildbot' invocations you perform therein how to
|
|
get to the buildmaster associated with that tree's project.
|
|
|
|
Windows users get something similar, using %APPDATA%/buildbot instead of
|
|
~/.buildbot .
|
|
|
|
** windows ShellCommands are launched with 'cmd.exe'
|
|
|
|
The buildslave has been modified to run all list-based ShellCommands by
|
|
prepending [os.environ['COMSPEC'], '/c'] to the argv list before execution.
|
|
This should allow the buildslave's PATH to be searched for commands,
|
|
improving the chances that it can run the same 'trial -o foo' commands as a
|
|
unix buildslave. The potential downside is that spaces in argv elements might
|
|
be re-parsed, or quotes might be re-interpreted. The consensus on the mailing
|
|
list was that this is a useful thing to do, but please report any problems
|
|
you encounter with it.
|
|
|
|
** minor features
|
|
|
|
The Waterfall display now shows the buildbot's home timezone at the top of
|
|
the timestamp column. The default favicon.ico is now much nicer-looking (it
|
|
is generated with Blender.. the icon.blend file is available in CVS in
|
|
docs/images/ should you care to play with it).
|
|
|
|
|
|
|
|
* Release 0.6.3 (25 Apr 2005)
|
|
|
|
** 'buildbot' tool gets more uses
|
|
|
|
The 'buildbot' executable has acquired three new subcommands. 'buildbot
|
|
debugclient' brings up the small remote-control panel that connects to a
|
|
buildmaster (via the slave port and the c['debugPassword']). This tool,
|
|
formerly in contrib/debugclient.py, lets you reload the config file, force
|
|
builds, and simulate inbound commit messages. It requires gtk2, glade, and
|
|
the python bindings for both to be installed.
|
|
|
|
'buildbot statusgui' brings up a live status client, formerly available by
|
|
running buildbot/clients/gtkPanes.py as a program. This connects to the PB
|
|
status port that you create with:
|
|
|
|
c['status'].append(client.PBListener(portnum))
|
|
|
|
and shows two boxes per Builder, one for the last build, one for current
|
|
activity. These boxes are updated in realtime. The effect is primitive, but
|
|
is intended as an example of what's possible with the PB status interface.
|
|
|
|
'buildbot statuslog' provides a text-based running log of buildmaster events.
|
|
|
|
Note: command names are subject to change. These should get much more useful
|
|
over time.
|
|
|
|
** web page has a favicon
|
|
|
|
When constructing the html.Waterfall instance, you can provide the filename
|
|
of an image that will be provided when the "favicon.ico" resource is
|
|
requested. Many web browsers display this as an icon next to the URL or
|
|
bookmark. A goofy little default icon is included.
|
|
|
|
** web page has CSS
|
|
|
|
Thanks to Thomas Vander Stichele, the Waterfall page is now themable through
|
|
CSS. The default CSS is located in buildbot/status/classic.css, and creates a
|
|
page that is mostly identical to the old, non-CSS based table.
|
|
|
|
You can specify a different CSS file to use by passing it as the css=
|
|
argument to html.Waterfall(). See the docstring for Waterfall for some more
|
|
details.
|
|
|
|
** builder "categories"
|
|
|
|
Thomas has added code which places each Builder in an optional "category".
|
|
The various status targets (Waterfall, IRC, MailNotifier) can accept a list
|
|
of categories, and they will ignore any activity in builders outside this
|
|
list. This makes it easy to create some Builders which are "experimental" or
|
|
otherwise not yet ready for the world to see, or indicate that certain
|
|
builders should not harass developers when their tests fail, perhaps because
|
|
the build slaves for them are not yet fully functional.
|
|
|
|
** Deprecated features
|
|
|
|
*** defining Builders with tuples is deprecated
|
|
|
|
For a long time, the preferred way to define builders in the config file has
|
|
been with a dictionary. The less-flexible old style of a 4-item tuple (name,
|
|
slavename, builddir, factory) is now officially deprecated (i.e., it will
|
|
emit a warning if you use it), and will be removed in the next release.
|
|
Dictionaries are more flexible: additional keys like periodicBuildTime are
|
|
simply unavailable to tuple-defined builders.
|
|
|
|
Note: it is a good idea to watch the logfile (usually in twistd.log) when you
|
|
first start the buildmaster, or whenever you reload the config file. Any
|
|
warnings or errors in the config file will be found there.
|
|
|
|
*** c['webPortnum'], c['webPathname'], c['irc'] are deprecated
|
|
|
|
All status reporters should be defined in the c['status'] array, using
|
|
buildbot.status.html.Waterfall or buildbot.status.words.IRC . These have been
|
|
deprecated for a while, but this is fair warning that these keys will be
|
|
removed in the next release.
|
|
|
|
*** c['manholePort'] is deprecated
|
|
|
|
Again, this has been deprecated for a while, in favor of:
|
|
|
|
c['manhole'] = master.Manhole(port, username, password)
|
|
|
|
The preferred syntax will eventually let us use other, better kinds of debug
|
|
shells, such as the experimental curses-based ones in the Twisted sandbox
|
|
(which would offer command-line editing and history).
|
|
|
|
** bug fixes
|
|
|
|
The waterfall page has been improved a bit. A circular-reference bug in the
|
|
web page's TextLog class was fixed, which caused a major memory leak in a
|
|
long-running buildmaster with large logfiles that are viewed frequently.
|
|
Modifying the config file in a way which only changed a builder's base
|
|
directory now works correctly. The 'buildbot' command tries to create
|
|
slightly more useful master/slave directories, adding a Makefile entry to
|
|
re-create the .tap file, and removing global-read permissions from the files
|
|
that may contain buildslave passwords.
|
|
|
|
** twisted-2.0.0 compatibility
|
|
|
|
Both buildmaster and buildslave should run properly under Twisted-2.0 . There
|
|
are still some warnings about deprecated functions, some of which could be
|
|
fixed, but there are others that would require removing compatibility with
|
|
Twisted-1.3, and I don't expect to do that until 2.0 has been out and stable
|
|
for at least several months. The unit tests should pass under 2.0, whereas
|
|
the previous buildbot release had tests which could hang when run against the
|
|
new "trial" framework in 2.0.
|
|
|
|
The Twisted-specific steps (including Trial) have been updated to match 2.0
|
|
functionality.
|
|
|
|
** win32 compatibility
|
|
|
|
Thankt to Nick Trout, more compatibility fixes have been incorporated,
|
|
improving the chances that the unit tests will pass on windows systems. There
|
|
are still some problems, and a step-by-step "running buildslaves on windows"
|
|
document would be greatly appreciated.
|
|
|
|
** API docs
|
|
|
|
Thanks to Thomas Vander Stichele, most of the docstrings have been converted
|
|
to epydoc format. There is a utility in docs/gen-reference to turn these into
|
|
a tree of cross-referenced HTML pages. Eventually these docs will be
|
|
auto-generated and somehow published on the buildbot web page.
|
|
|
|
|
|
|
|
* Release 0.6.2 (13 Dec 2004)
|
|
|
|
** new features
|
|
|
|
It is now possible to interrupt a running build. Both the web page and the
|
|
IRC bot feature 'stop build' commands, which can be used to interrupt the
|
|
current BuildStep and accelerate the termination of the overall Build. The
|
|
status reporting for these still leaves something to be desired (an
|
|
'interrupt' event is pushed into the column, and the reason for the interrupt
|
|
is added to a pseudo-logfile for the step that was stopped, but if you only
|
|
look at the top-level status it appears that the build failed on its own).
|
|
|
|
Builds are also halted if the connection to the buildslave is lost. On the
|
|
slave side, any active commands are halted if the connection to the
|
|
buildmaster is lost.
|
|
|
|
** minor new features
|
|
|
|
The IRC log bot now reports ETA times in a MMSS format like "2m45s" instead
|
|
of the clunky "165 seconds".
|
|
|
|
** bug fixes
|
|
|
|
*** Slave Disconnect
|
|
|
|
Slave disconnects should be handled better now: the current build should be
|
|
abandoned properly. Earlier versions could get into weird states where the
|
|
build failed to finish, clogging the builder forever (or at least until the
|
|
buildmaster was restarted).
|
|
|
|
In addition, there are weird network conditions which could cause a
|
|
buildslave to attempt to connect twice to the same buildmaster. This can
|
|
happen when the slave is sending large logfiles over a slow link, while using
|
|
short keepalive timeouts. The buildmaster has been fixed to allow the second
|
|
connection attempt to take precedence over the first, so that the older
|
|
connection is jettisoned to make way for the newer one.
|
|
|
|
In addition, the buildslave has been fixed to be less twitchy about timeouts.
|
|
There are now two parameters: keepaliveInterval (which is controlled by the
|
|
mktap 'keepalive' argument), and keepaliveTimeout (which requires editing the
|
|
.py source to change from the default of 30 seconds). The slave expects to
|
|
see *something* from the master at least once every keepaliveInterval
|
|
seconds, and will try to provoke a response (by sending a keepalive request)
|
|
'keepaliveTimeout' seconds before the end of this interval just in case there
|
|
was no regular traffic. Any kind of traffic will qualify, including
|
|
acknowledgements of normal build-status updates.
|
|
|
|
The net result is that, as long as any given PB message can be sent over the
|
|
wire in less than 'keepaliveTimeout' seconds, the slave should not mistakenly
|
|
disconnect because of a timeout. There will be traffic on the wire at least
|
|
every 'keepaliveInterval' seconds, which is what you want to pay attention to
|
|
if you're trying to keep an intervening NAT box from dropping what it thinks
|
|
is an abandoned connection. A quiet loss of connection will be detected
|
|
within 'keepaliveInterval' seconds.
|
|
|
|
*** Large Logfiles
|
|
|
|
The web page rendering code has been fixed to deliver large logfiles in
|
|
pieces, using a producer/consumer apparatus. This avoids the large spike in
|
|
memory consumption when the log file body was linearized into a single string
|
|
and then buffered in the socket's application-side transmit buffer. This
|
|
should also avoid the 640k single-string limit for web.distrib servers that
|
|
could be hit by large (>640k) logfiles.
|
|
|
|
|
|
|
|
* Release 0.6.1 (23 Nov 2004)
|
|
|
|
** win32 improvements/bugfixes
|
|
|
|
Several changes have gone in to improve portability to non-unix systems. It
|
|
should be possible to run a build slave under windows without major issues
|
|
(although step-by-step documentation is still greatly desired: check the
|
|
mailing list for suggestions from current win32 users).
|
|
|
|
*** PBChangeSource: use configurable directory separator, not os.sep
|
|
|
|
The PBChangeSource, which listens on a TCP socket for change notices
|
|
delivered from tools like contrib/svn_buildbot.py, was splitting source
|
|
filenames with os.sep . This is inappropriate, because those file names are
|
|
coming from the VC repository, not the local filesystem, and the repository
|
|
host may be running a different OS (with a different separator convention)
|
|
than the buildmaster host. In particular, a win32 buildmaster using a CVS
|
|
repository running on a unix box would be confused.
|
|
|
|
PBChangeSource now takes a sep= argument to indicate the separator character
|
|
to use.
|
|
|
|
*** build saving should work better
|
|
|
|
windows cannot do the atomic os.rename() trick that unix can, so under win32
|
|
the buildmaster falls back to save/delete-old/rename, which carries a slight
|
|
risk of losing a saved build log (if the system were to crash between the
|
|
delete-old and the rename).
|
|
|
|
** new features
|
|
|
|
*** test-result tracking
|
|
|
|
Work has begun on fine-grained test-result handling. The eventual goal is to
|
|
be able to track individual tests over time, and create problem reports when
|
|
a test starts failing (which then are resolved when the test starts passing
|
|
again). The first step towards this is an ITestResult interface, and code in
|
|
the TrialTestParser to create such results for all non-passing tests (the
|
|
ones for which Trial emits exception tracebacks).
|
|
|
|
These test results are currently displayed in a tree-like display in a page
|
|
accessible from each Build's page (follow the numbered link in the yellow
|
|
box at the start of each build to get there).
|
|
|
|
This interface is still in flux, as it really wants to be able to accomodate
|
|
things like compiler warnings and tests that are skipped because of missing
|
|
libraries or unsupported architectures.
|
|
|
|
** bug fixes
|
|
|
|
*** VC updates should survive temporary failures
|
|
|
|
Some VC systems (CVS and SVN in particular) get upset when files are turned
|
|
into directories or vice versa, or when repository items are moved without
|
|
the knowledge of the VC system. The usual symptom is that a 'cvs update'
|
|
fails where a fresh checkout succeeds.
|
|
|
|
To avoid having to manually intervene, the build slaves' VC commands have
|
|
been refactored to respond to update failures by deleting the tree and
|
|
attempting a full checkout. This may cause some unnecessary effort when,
|
|
e.g., the CVS server falls off the net, but in the normal case it will only
|
|
come into play when one of these can't-cope situations arises.
|
|
|
|
*** forget about an existing build when the slave detaches
|
|
|
|
If the slave was lost during a build, the master did not clear the
|
|
.currentBuild reference, making that builder unavailable for later builds.
|
|
This has been fixed, so that losing a slave should be handled better. This
|
|
area still needs some work, I think it's still possible to get both the
|
|
slave and the master wedged by breaking the connection at just the right
|
|
time. Eventually I want to be able to resume interrupted builds (especially
|
|
when the interruption is the result of a network failure and not because the
|
|
slave or the master actually died).
|
|
|
|
*** large logfiles now consume less memory
|
|
|
|
Build logs are stored as lists of (type,text) chunks, so that
|
|
stdout/stderr/headers can be displayed differently (if they were
|
|
distinguishable when they were generated: stdout and stderr are merged when
|
|
usePTY=1). For multi-megabyte logfiles, a large list with many short strings
|
|
could incur a large overhead. The new behavior is to merge same-type string
|
|
chunks together as they are received, aiming for a chunk size of about 10kb,
|
|
which should bring the overhead down to a more reasonable level.
|
|
|
|
There remains an issue with actually delivering large logfiles over, say,
|
|
the HTML interface. The string chunks must be merged together into a single
|
|
string before delivery, which causes a spike in the memory usage when the
|
|
logfile is viewed. This can also break twisted.web.distrib -type servers,
|
|
where the underlying PB protocol imposes a 640k limit on the size of
|
|
strings. This will be fixed (with a proper Producer/Consumer scheme) in the
|
|
next release.
|
|
|
|
|
|
* Release 0.6.0 (30 Sep 2004)
|
|
|
|
** new features
|
|
|
|
*** /usr/bin/buildbot control tool
|
|
|
|
There is now an executable named 'buildbot'. For now, this just provides a
|
|
convenient front-end to mktap/twistd/kill, but eventually it will provide
|
|
access to other client functionality (like the 'try' builds, and a status
|
|
client). Assuming you put your buildbots in /var/lib/buildbot/master/FOO,
|
|
you can do 'buildbot create-master /var/lib/buildbot/master/FOO' and it will
|
|
create the .tap file and set up a sample master.cfg for you. Later,
|
|
'buildbot start /var/lib/buildbot/master/FOO' will start the daemon.
|
|
|
|
|
|
*** build status now saved in external files, -shutdown.tap unnecessary
|
|
|
|
The status rewrite included a change to save all build status in a set of
|
|
external files. These files, one per build, are put in a subdirectory of the
|
|
master's basedir (named according to the 'builddir' parameter of the Builder
|
|
configuration dictionary). This helps keep the buildmaster's memory
|
|
consumption small: the (potentially large) build logs are kept on disk
|
|
instead of in RAM. There is a small cache (2 builds per builder) kept in
|
|
memory, but everything else lives on disk.
|
|
|
|
The big change is that the buildmaster now keeps *all* status in these
|
|
files. It is no longer necessary to preserve the buildbot-shutdown.tap file
|
|
to run a persistent buildmaster. The buildmaster may be launched with
|
|
'twistd -f buildbot.tap' each time, in fact the '-n' option can be added to
|
|
prevent twistd from automatically creating the -shutdown.tap file.
|
|
|
|
There is still one lingering bug with this change: the Expectations object
|
|
for each builder (which records how long the various steps took, to provide
|
|
an ETA value for the next time) is not yet saved. The result is that the
|
|
first build after a restart will not provide an ETA value.
|
|
|
|
0.6.0 keeps status in a single file per build, as opposed to 0.5.0 which
|
|
kept status in many subdirectories (one layer for builds, another for steps,
|
|
and a third for logs). 0.6.0 will detect and delete these subdirectories as
|
|
it overwrites them.
|
|
|
|
The saved builds are optional. To prevent disk usage from growing without
|
|
bounds, you may want to set up a cron job to run 'find' and delete any which
|
|
are too old. The status displays will happily survive without those saved
|
|
build objects.
|
|
|
|
The set of recorded Changes is kept in a similar file named 'changes.pck'.
|
|
|
|
|
|
*** source checkout now uses timestamp/revision
|
|
|
|
Source checkouts are now performed with an appropriate -D TIMESTAMP (for
|
|
CVS) or -r REVISION (for SVN) marker to obtain the exact sources that were
|
|
specified by the most recent Change going into the current Build. This
|
|
avoids a race condition in which a change might be committed after the build
|
|
has started but before the source checkout has completed, resulting in a
|
|
mismatched set of source files. Such changes are now ignored.
|
|
|
|
This works by keeping track of repository-wide revision/transaction numbers
|
|
(for version control systems that offer them, like SVN). The checkout or
|
|
update is performed with the highest such revision number. For CVS (which
|
|
does not have them), the timestamp of each commit message is used, and a -D
|
|
argument is created to place the checkout squarely in the middle of the "tree
|
|
stable timer"'s window.
|
|
|
|
This also provides the infrastructure for the upcoming 'try' feature. All
|
|
source-checkout commands can now obtain a base revision marker and a patch
|
|
from the Build, allowing certain builds to be performed on something other
|
|
than the most recent sources.
|
|
|
|
See source.xhtml and steps.xhtml for details.
|
|
|
|
|
|
*** Darcs and Arch support added
|
|
|
|
There are now build steps which retrieve a source tree from Darcs and Arch
|
|
repositories. See steps.xhtml for details.
|
|
|
|
Preliminary P4 support has been added, thanks to code from Dave Peticolas.
|
|
You must manually set up each build slave with an appropriate P4CLIENT: all
|
|
buildbot does is run 'p4 sync' at the appropriate times.
|
|
|
|
|
|
*** Status reporting rewritten
|
|
|
|
Status reporting was completely revamped. The config file now accepts a
|
|
BuildmasterConfig['status'] entry, with a list of objects that perform status
|
|
delivery. The old config file entries which controlled the web status port
|
|
and the IRC bot have been deprecated in favor of adding instances to
|
|
['status']. The following status-delivery classes have been implemented, all
|
|
in the 'buildbot.status' package:
|
|
|
|
client.PBListener(port, username, passwd)
|
|
html.Waterfall(http_port, distrib_port)
|
|
mail.MailNotifier(fromaddr, mode, extraRecipients..)
|
|
words.IRC(host, nick, channels)
|
|
|
|
See the individual docstrings for details about how to use each one. You can
|
|
create new status-delivery objects by following the interfaces found in the
|
|
buildbot.interfaces module.
|
|
|
|
|
|
*** BuildFactory configuration process changed
|
|
|
|
The basic BuildFactory class is now defined in buildbot.process.factory
|
|
rather than buildbot.process.base, so you will have to update your config
|
|
files. factory.BuildFactory is the base class, which accepts a list of Steps
|
|
to run. See docs/factories.xhtml for details.
|
|
|
|
There are now easier-to-use BuildFactory classes for projects which use GNU
|
|
Autoconf, perl's MakeMaker (CPAN), python's distutils (but no unit tests),
|
|
and Twisted's Trial. Each one takes a separate 'source' Step to obtain the
|
|
source tree, and then fills in the rest of the Steps for you.
|
|
|
|
|
|
*** CVS/SVN VC steps unified, simplified
|
|
|
|
The confusing collection of arguments for the CVS step ('clobber=',
|
|
'copydir=', and 'export=') have been removed in favor of a single 'mode'
|
|
argument. This argument describes how you want to use the sources: whether
|
|
you want to update and compile everything in the same tree (mode='update'),
|
|
or do a fresh checkout and full build each time (mode='clobber'), or
|
|
something in between.
|
|
|
|
The SVN (Subversion) step has been unified and accepts the same mode=
|
|
parameter as CVS. New version control steps will obey the same interface.
|
|
|
|
Most of the old configuration arguments have been removed. You will need to
|
|
update your configuration files to use the new arguments. See
|
|
docs/steps.xhtml for a description of all the new parameters.
|
|
|
|
|
|
*** Preliminary Debian packaging added
|
|
|
|
Thanks to the contributions of Kirill Lapshin, we can now produce .deb
|
|
installer packages. These are still experimental, but they include init.d
|
|
startup/shutdown scripts, which the the new /usr/bin/buildbot to invoke
|
|
twistd. Create your buildmasters in /var/lib/buildbot/master/FOO, and your
|
|
slaves in /var/lib/buildbot/slave/BAR, then put FOO and BAR in the
|
|
appropriate places in /etc/default/buildbot . After that, the buildmasters
|
|
and slaves will be started at every boot.
|
|
|
|
Pre-built .debs are not yet distributed. Use 'debuild -uc -us' from the
|
|
source directory to create them.
|
|
|
|
|
|
** minor features
|
|
|
|
|
|
*** Source Stamps
|
|
|
|
Each build now has a "source stamp" which describes what sources it used. The
|
|
idea is that the sources for this particular build can be completely
|
|
regenerated from the stamp. The stamp is a tuple of (revision, patch), where
|
|
the revision depends on the VC system being used (for CVS it is either a
|
|
revision tag like "BUILDBOT-0_5_0" or a datestamp like "2004/07/23", for
|
|
Subversion it is a revision number like 11455). This must be combined with
|
|
information from the Builder that is constant across all builds (something to
|
|
point at the repository, and possibly a branch indicator for CVS and other VC
|
|
systems that don't fold this into the repository string).
|
|
|
|
The patch is an optional unified diff file, ready to be applied by running
|
|
'patch -p0 <PATCH' from inside the workdir. This provides support for the
|
|
'try' feature that will eventually allow developers to run buildbot tests on
|
|
their code before checking it in.
|
|
|
|
|
|
*** SIGHUP causes the buildmaster's configuration file to be re-read
|
|
|
|
*** IRC bot now has 'watch' command
|
|
|
|
You can now tell the buildbot's IRC bot to 'watch <buildername>' on a builder
|
|
which is currently performing a build. When that build is finished, the
|
|
buildbot will make an announcement (including the results of the build).
|
|
|
|
The IRC 'force build' command will also announce when the resulting build has
|
|
completed.
|
|
|
|
|
|
*** the 'force build' option on HTML and IRC status targets can be disabled
|
|
|
|
The html.Waterfall display and the words.IRC bot may be constructed with an
|
|
allowForce=False argument, which removes the ability to force a build through
|
|
these interfaces. Future versions will be able to restrict this build-forcing
|
|
capability to authenticated users. The per-builder HTML page no longer
|
|
displays the 'Force Build' buttons if it does not have this ability. Thanks
|
|
to Fred Drake for code and design suggestions.
|
|
|
|
|
|
*** master now takes 'projectName' and 'projectURL' settings
|
|
|
|
These strings allow the buildbot to describe what project it is working for.
|
|
At the moment they are only displayed on the Waterfall page, but in the next
|
|
release they will be retrieveable from the IRC bot as well.
|
|
|
|
|
|
*** survive recent (SVN) Twisted versions
|
|
|
|
The buildbot should run correctly (albeit with plenty of noisy deprecation
|
|
warnings) under the upcoming Twisted-2.0 release.
|
|
|
|
|
|
*** work-in-progress realtime Trial results acquisition
|
|
|
|
Jonathan Simms (<slyphon>) has been working on 'retrial', a rewrite of
|
|
Twisted's unit test framework that will most likely be available in
|
|
Twisted-2.0 . Although it is not yet complete, the buildbot will be able to
|
|
use retrial in such a way that build status is reported on a per-test basis,
|
|
in real time. This will be the beginning of fine-grained test tracking and
|
|
Problem management, described in docs/users.xhtml .
|
|
|
|
|
|
* Release 0.5.0 (22 Jul 2004)
|
|
|
|
** new features
|
|
|
|
*** web.distrib servers via TCP
|
|
|
|
The 'webPathname' config option, which specifies a UNIX socket on which to
|
|
publish the waterfall HTML page (for use by 'mktap web -u' or equivalent),
|
|
now accepts a numeric port number. This publishes the same thing via TCP,
|
|
allowing the parent web server to live on a separate machine.
|
|
|
|
This config option could be named better, but it will go away altogether in
|
|
a few releases, when status delivery is unified. It will be replaced with a
|
|
WebStatusTarget object, and the config file will simply contain a list of
|
|
various kinds of status targets.
|
|
|
|
*** 'master.cfg' filename is configurable
|
|
|
|
The buildmaster can use a config file named something other than
|
|
"master.cfg". Use the --config=foo.cfg option to mktap to control this.
|
|
|
|
*** FreshCVSSource now uses newcred (CVSToys >= 1.0.10)
|
|
|
|
The FreshCVSSource class now defaults to speaking to freshcvs daemons from
|
|
modern CVSToys releases. If you need to use the buildbot with a daemon from
|
|
CVSToys-1.0.9 or earlier, use FreshCVSSourceOldcred instead. Note that the
|
|
new form only requires host/port/username/passwd: the "serviceName"
|
|
parameter is no longer meaningful.
|
|
|
|
*** Builders are now configured with a dictionary, not a tuple
|
|
|
|
The preferred way to set up a Builder in master.cfg is to provide a
|
|
dictionary with various keys, rather than a (non-extensible) 4-tuple. See
|
|
docs/config.xhtml for details. The old tuple-way is still supported for now,
|
|
it will probably be deprecated in the next release and removed altogether in
|
|
the following one.
|
|
|
|
*** .periodicBuildTime is now exposed to the config file
|
|
|
|
To set a builder to run at periodic intervals, simply add a
|
|
'periodicBuildTime' key to its master.cfg dictionary. Again, see
|
|
docs/config.xhtml for details.
|
|
|
|
*** svn_buildbot.py adds --include, --exclude
|
|
|
|
The commit trigger script now gives you more control over which files are
|
|
sent to the buildmaster and which are not.
|
|
|
|
*** usePTY is controllable at slave mktap time
|
|
|
|
The buildslaves usually run their child processes in a pty, which creates a
|
|
process group for all the children, which makes it much easier to kill them
|
|
all at once (i.e. if a test hangs). However this causes problems on some
|
|
systems. Rather than hacking slavecommand.py to disable the use of these
|
|
ptys, you can now create the slave's .tap file with --usepty=0 at mktap
|
|
time.
|
|
|
|
** Twisted changes
|
|
|
|
A summary of warnings (e.g. DeprecationWarnings) is provided as part of the
|
|
test-case summarizer. The summarizer also counts Skips, expectedFailures,
|
|
and unexpectedSuccesses, displaying the counts on the test step's event box.
|
|
|
|
The RunUnitTests step now uses "trial -R twisted" instead of "trial
|
|
twisted.test", which is a bit cleaner. All .pyc files are deleted before
|
|
starting trial, to avoid getting tripped up by deleted .py files.
|
|
|
|
** documentation
|
|
|
|
docs/config.xhtml now describes the syntax and allowed contents of the
|
|
'master.cfg' configuration file.
|
|
|
|
** bugfixes
|
|
|
|
Interlocks had a race condition that could cause the lock to get stuck
|
|
forever.
|
|
|
|
FreshCVSSource has a prefix= argument that was moderately broken (it used to
|
|
only work if the prefix was a single directory component). It now works with
|
|
subdirectories.
|
|
|
|
The buildmaster used to complain when it saw the "info" directory in a
|
|
slave's workspace. This directory is used to publish information about the
|
|
slave host and its administrator, and is not a leftover build directory as
|
|
the complaint suggested. This complain has been silenced.
|
|
|
|
|
|
* Release 0.4.3 (30 Apr 2004)
|
|
|
|
** PBChangeSource made explicit
|
|
|
|
In 0.4.2 and before, an internal interface was available which allowed
|
|
special clients to inject changes into the Buildmaster. This interface is
|
|
used by the contrib/svn_buildbot.py script. The interface has been extracted
|
|
into a proper PBChangeSource object, which should be created in the
|
|
master.cfg file just like the other kinds of ChangeSources. See
|
|
docs/sources.xhtml for details.
|
|
|
|
If you were implicitly using this change source (for example, if you use
|
|
Subversion and the svn_buildbot.py script), you *must* add this source to
|
|
your master.cfg file, or changes will not be delivered and no builds will be
|
|
triggered.
|
|
|
|
The PBChangeSource accepts the same "prefix" argument as all other
|
|
ChangeSources. For a SVN repository that follows the recommended practice of
|
|
using "trunk/" for the trunk revisions, you probably want to construct the
|
|
source like this:
|
|
|
|
source = PBChangeSource(prefix="trunk")
|
|
|
|
to make sure that the Builders are given sensible (trunk-relative)
|
|
filenames for each changed source file.
|
|
|
|
** Twisted changes
|
|
|
|
*** step_twisted.RunUnitTests can change "bin/trial"
|
|
|
|
The twisted RunUnitTests step was enhanced to let you run something other
|
|
than "bin/trial", making it easier to use a buildbot on projects which use
|
|
Twisted but aren't actually Twisted itself.
|
|
|
|
*** Twisted now uses Subversion
|
|
|
|
Now that Twisted has moved from CVS to SVN, the Twisted build processes have
|
|
been modified to perform source checkouts from the Subversion repository.
|
|
|
|
** minor feature additions
|
|
|
|
*** display Changes with HTML
|
|
|
|
Changes are displayed with a bit more pizazz, and a links= argument was
|
|
added to allow things like ViewCVS links to be added to the display
|
|
(although it is not yet clear how this argument should be used: the
|
|
interface remains subject to change untill it has been documented).
|
|
|
|
*** display ShellCommand logs with HTML
|
|
|
|
Headers are in blue, stderr is in red (unless usePTY=1 in which case stderr
|
|
and stdout are indistinguishable). A link is provided which returns the same
|
|
contents as plain text (by appending "?text=1" to the URL).
|
|
|
|
*** buildslaves send real tracebacks upon error
|
|
|
|
The .unsafeTracebacks option has been turned on for the buildslaves,
|
|
allowing them to send a full stack trace when an exception occurs, which is
|
|
logged in the buildmaster's twistd.log file. This makes it much easier to
|
|
determine what went wrong on the slave side.
|
|
|
|
*** BasicBuildFactory refactored
|
|
|
|
The BasicBuildFactory class was refactored to make it easier to create
|
|
derivative classes, in particular the BasicSVN variant.
|
|
|
|
*** "ping buildslave" web button added
|
|
|
|
There is now a button on the "builder information" page that lets a web user
|
|
initiate a ping of the corresponding build slave (right next to the button
|
|
that lets them force a build). This was added to help track down a problem
|
|
with the slave keepalives.
|
|
|
|
** bugs fixed:
|
|
|
|
You can now have multiple BuildSteps with the same name (the names are used
|
|
as hash keys in the data structure that helps determine ETA values for each
|
|
step, the new code creates unique key names if necessary to avoid
|
|
collisions). This means that, for example, you do not have to create a
|
|
BuildStep subclass just to have two Compile steps in the same process.
|
|
|
|
If CVSToys is not installed, the tests that depend upon it are skipped.
|
|
|
|
Some tests in 0.4.2 failed because of a missing set of test files, they are
|
|
now included in the tarball properly.
|
|
|
|
Slave keepalives should work better now in the face of silent connection
|
|
loss (such as when an intervening NAT box times out the association), the
|
|
connection should be reestablished in minutes instead of hours.
|
|
|
|
Shell commands on the slave are invoked with an argument list instead of the
|
|
ugly and error-prone split-on-spaces approach. If the ShellCommand is given
|
|
a string (instead of a list), it will fall back to splitting on spaces.
|
|
Shell commands should work on win32 now (using COMSPEC instead of /bin/sh).
|
|
|
|
Buildslaves under w32 should theoretically work now, and one was running for
|
|
the Twisted buildbot for a while until the machine had to be returned.
|
|
|
|
The "header" lines in ShellCommand logs (which include the first line, that
|
|
displays the command being run, and the last, which shows its exit status)
|
|
are now generated by the buildslave side instead of the local (buildmaster)
|
|
side. This can provide better error handling and is generally cleaner.
|
|
However, if you have an old buildslave (running 0.4.2 or earlier) and a new
|
|
buildmaster, then neither end will generate these header lines.
|
|
|
|
CVSCommand was improved, in certain situations 0.4.2 would perform
|
|
unnecessary checkouts (when an update would have sufficed). Thanks to Johan
|
|
Dahlin for the patches. The status output was fixed as well, so that
|
|
failures in CVS and SVN commands (such as not being able to find the 'svn'
|
|
executable) make the step status box red.
|
|
|
|
Subversion support was refactored to make it behave more like CVS. This is a
|
|
work in progress and will be improved in the next release.
|
|
|
|
|
|
* Release 0.4.2 (08 Jan 2004)
|
|
|
|
** test suite updated
|
|
|
|
The test suite has been completely moved over to Twisted's "Trial"
|
|
framework, and all tests now pass. To run the test suite (consisting of 64
|
|
tests, probably covering about 30% of BuildBot's logic), do this:
|
|
|
|
PYTHONPATH=. trial -v buildbot.test
|
|
|
|
** Mail parsers updated
|
|
|
|
Several bugs in the mail-parsing code were fixed, allowing a buildmaster to
|
|
be triggered by mail sent out by a CVS repository. (The Twisted Buildbot is
|
|
now using this to trigger builds, as their CVS server machine is having some
|
|
difficulties with FreshCVS). The FreshCVS mail format for directory
|
|
additions appears to have changed recently: the new parser should handle
|
|
both old and new-style messages.
|
|
|
|
A parser for Bonsai commit messages (buildbot.changes.mail.parseBonsaiMail)
|
|
was contributed by Stephen Davis. Thanks Stephen!
|
|
|
|
** CVS "global options" now available
|
|
|
|
The CVS build step can now accept a list of "global options" to give to the
|
|
cvs command. These go before the "update"/"checkout" word, and are described
|
|
fully by "cvs --help-options". Two useful ones might be "-r", which causes
|
|
checked-out files to be read-only, and "-R", which assumes the repository is
|
|
read-only (perhaps by not attempting to write to lock files).
|
|
|
|
|
|
* Release 0.4.1 (09 Dec 2003)
|
|
|
|
** MaildirSources fixed
|
|
|
|
Several bugs in MaildirSource made them unusable. These have been fixed (for
|
|
real this time). The Twisted buildbot is using an FCMaildirSource while they
|
|
fix some FreshCVS daemon problems, which provided the encouragement for
|
|
getting these bugs fixed.
|
|
|
|
In addition, the use of DNotify (only available under linux) was somehow
|
|
broken, possibly by changes in some recent version of Python. It appears to
|
|
be working again now (against both python-2.3.3c1 and python-2.2.1).
|
|
|
|
** master.cfg can use 'basedir' variable
|
|
|
|
As documented in the sample configuration file (but not actually implemented
|
|
until now), a variable named 'basedir' is inserted into the namespace used
|
|
by master.cfg . This can be used with something like:
|
|
|
|
os.path.join(basedir, "maildir")
|
|
|
|
to obtain a master-basedir-relative location.
|
|
|
|
|
|
* Release 0.4.0 (05 Dec 2003)
|
|
|
|
** newapp
|
|
|
|
I've moved the codebase to Twisted's new 'application' framework, which
|
|
drastically cleans up service startup/shutdown just like newcred did for
|
|
authorization. This is mostly an internal change, but the interface to
|
|
IChangeSources was modified, so in the off chance that someone has written a
|
|
custom change source, it may have to be updated to the new scheme.
|
|
|
|
The most user-visible consequence of this change is that now both
|
|
buildmasters and buildslaves are generated with the standard Twisted 'mktap'
|
|
utility. Basic documentation is in the README file.
|
|
|
|
Both buildmaster and buildslave .tap files need to be re-generated to run
|
|
under the new code. I have not figured out the styles.Versioned upgrade path
|
|
well enough to avoid this yet. Sorry.
|
|
|
|
This also means that both buildslaves and the buildmaster require
|
|
Twisted-1.1.0 or later.
|
|
|
|
** reloadable master.cfg
|
|
|
|
Most aspects of a buildmaster is now controlled by a configuration file
|
|
which can be re-read at runtime without losing build history. This feature
|
|
makes the buildmaster *much* easier to maintain.
|
|
|
|
In the previous release, you would create the buildmaster by writing a
|
|
program to define the Builders and ChangeSources and such, then run it to
|
|
create the .tap file. In the new release, you use 'mktap' to create the .tap
|
|
file, and the only parameter you give it is the base directory to use. Each
|
|
time the buildmaster starts, it will look for a file named 'master.cfg' in
|
|
that directory and parse it as a python script. That script must define a
|
|
dictionary named 'BuildmasterConfig' with various keys to define the
|
|
builders, the known slaves, what port to use for the web server, what IRC
|
|
channels to connect to, etc.
|
|
|
|
This config file can be re-read at runtime, and the buildmaster will compute
|
|
the differences and add/remove services as necessary. The re-reading is
|
|
currently triggered through the debug port (contrib/debugclient.py is the
|
|
debug port client), but future releases will add the ability to trigger the
|
|
reconfiguration by IRC command, web page button, and probably a local UNIX
|
|
socket (with a helper script to trigger a rebuild locally).
|
|
|
|
docs/examples/twisted_master.cfg contains a sample configuration file, which
|
|
also lists all the keys that can be set.
|
|
|
|
There may be some bugs lurking, such as re-configuring the buildmaster while
|
|
a build is running. It needs more testing.
|
|
|
|
** MaxQ support
|
|
|
|
Radix contributed some support scripts to run MaxQ test scripts. MaxQ
|
|
(http://maxq.tigris.org/) is a web testing tool that allows you to record
|
|
HTTP sessions and play them back.
|
|
|
|
** Builders can now wait on multiple Interlocks
|
|
|
|
The "Interlock" code has been enhanced to allow multiple builders to wait on
|
|
each one. This was done to support the new config-file syntax for specifying
|
|
Interlocks (in which each interlock is a tuple of A and [B], where A is the
|
|
builder the Interlock depends upon, and [B] is a list of builders that
|
|
depend upon the Interlock).
|
|
|
|
"Interlock" is misnamed. In the next release it will be changed to
|
|
"Dependency", because that's what it really expresses. A new class (probably
|
|
called Interlock) will be created to express the notion that two builders
|
|
should not run at the same time, useful when multiple builders are run on
|
|
the same machine and thrashing results when several CPU- or disk- intensive
|
|
compiles are done simultaneously.
|
|
|
|
** FreshCVSSource can now handle newcred-enabled FreshCVS daemons
|
|
|
|
There are now two FreshCVSSource classes: FreshCVSSourceNewcred talks to
|
|
newcred daemons, and FreshCVSSourceOldcred talks to oldcred ones. Mind you,
|
|
FreshCVS doesn't yet do newcred, but when it does, we'll be ready.
|
|
|
|
'FreshCVSSource' maps to the oldcred form for now. That will probably change
|
|
when the current release of CVSToys supports newcred by default.
|
|
|
|
** usePTY=1 on posix buildslaves
|
|
|
|
When a buildslave is running under POSIX (i.e. pretty much everything except
|
|
windows), child processes are created with a pty instead of separate
|
|
stdin/stdout/stderr pipes. This makes it more likely that a hanging build
|
|
(when killed off by the timeout code) will have all its sub-childred cleaned
|
|
up. Non-pty children would tend to leave subprocesses running because the
|
|
buildslave was only able to kill off the top-level process (typically
|
|
'make').
|
|
|
|
Windows doesn't have any concept of ptys, so non-posix systems do not try to
|
|
enable them.
|
|
|
|
** mail parsers should actually work now
|
|
|
|
The email parsing functions (FCMaildirSource and SyncmailMaildirSource) were
|
|
broken because of my confused understanding of how python class methods
|
|
work. These sources should be functional now.
|
|
|
|
** more irc bot sillyness
|
|
|
|
The IRC bot can now perform half of the famous AYBABTO scene.
|
|
|
|
|
|
* Release 0.3.5 (19 Sep 2003)
|
|
|
|
** newcred
|
|
|
|
Buildbot has moved to "newcred", a new authorization framework provided by
|
|
Twisted, which is a good bit cleaner and easier to work with than the
|
|
"oldcred" scheme in older versions. This causes both buildmaster and
|
|
buildslaves to depend upon Twisted 1.0.7 or later. The interface to
|
|
'makeApp' has changed somewhat (the multiple kinds of remote connections all
|
|
use the same TCP port now).
|
|
|
|
Old buildslaves will get "_PortalWrapper instance has no attribute
|
|
'remote_username'" errors when they try to connect. They must be upgraded.
|
|
|
|
The FreshCVSSource uses PB to connect to the CVSToys server. This has been
|
|
upgraded to use newcred too. If you get errors (TODO: what do they look
|
|
like?) in the log when the buildmaster tries to connect, you need to upgrade
|
|
your FreshCVS service or use the 'useOldcred' argument when creating your
|
|
FreshCVSSource. This is a temporary hack to allow the buildmaster to talk to
|
|
oldcred CVSToys servers. Using it will trigger deprecation warnings. It will
|
|
go away eventually.
|
|
|
|
In conjunction with this change, makeApp() now accepts a password which can
|
|
be applied to the debug service.
|
|
|
|
** new features
|
|
|
|
*** "copydir" for CVS checkouts
|
|
|
|
The CVS build step can now accept a "copydir" parameter, which should be a
|
|
directory name like "source" or "orig". If provided, the CVS checkout is
|
|
done once into this directory, then copied into the actual working directory
|
|
for compilation etc. Later updates are done in place in the copydir, then
|
|
the workdir is replaced with a copy.
|
|
|
|
This reduces CVS bandwidth (update instead of full checkout) at the expense
|
|
of twice the disk space (two copies of the tree).
|
|
|
|
*** Subversion (SVN) support
|
|
|
|
Radix (Christopher Armstrong) contributed early support for building
|
|
Subversion-based trees. The new 'SVN' buildstep behaves roughly like the
|
|
'CVS' buildstep, and the contrib/svn_buildbot.py script can be used as a
|
|
checkin trigger to feed changes to a running buildmaster.
|
|
|
|
** notable bugfixes
|
|
|
|
*** .tap file generation
|
|
|
|
We no longer set the .tap filename, because the buildmaster/buildslave
|
|
service might be added to an existing .tap file and we shouldn't presume to
|
|
own the whole thing. You may want to manually rename the "buildbot.tap" file
|
|
to something more meaningful (like "buildslave-bot1.tap").
|
|
|
|
*** IRC reconnect
|
|
|
|
If the IRC server goes away (it was restarted, or the network connection was
|
|
lost), the buildmaster will now schedule a reconnect attempt.
|
|
|
|
*** w32 buildslave fixes
|
|
|
|
An "rm -rf" was turned into shutil.rmtree on non-posix systems.
|
|
|
|
|
|
* Release 0.3.4 (28 Jul 2003)
|
|
|
|
** IRC client
|
|
|
|
The buildmaster can now join a set of IRC channels and respond to simple
|
|
queries about builder status.
|
|
|
|
** slave information
|
|
|
|
The build slaves can now report information from a set of info/* files in
|
|
the slave base directory to the buildmaster. This will be used by the slave
|
|
administrator to announce details about the system hosting the slave,
|
|
contact information, etc. For now, info/admin should contain the name/email
|
|
of the person who is responsible for the buildslave, and info/host should
|
|
describe the system hosting the build slave (OS version, CPU speed, memory,
|
|
etc). The contents of these files are made available through the waterfall
|
|
display.
|
|
|
|
** change notification email parsers
|
|
|
|
A parser for Syncmail (syncmail.sourceforge.net) was added. SourceForge
|
|
provides examples of setting up syncmail to deliver CVS commit messages to
|
|
mailing lists, so hopefully this will make it easier for sourceforge-hosted
|
|
projects to set up a buildbot.
|
|
|
|
email processors were moved into buildbot.changes.mail . FCMaildirSource was
|
|
moved, and the compatibility location (buildbot.changes.freshcvsmail) will
|
|
go away in the next release.
|
|
|
|
** w32 buildslave ought to work
|
|
|
|
Some non-portable code was changed to make it more likely that the
|
|
buildslave will run under windows. The Twisted buildbot now has a
|
|
(more-or-less) working w32 buildslave.
|
|
|
|
|
|
* Release 0.3.3 (21 May 2003):
|
|
|
|
** packaging changes
|
|
|
|
*** include doc/examples in the release. Oops again.
|
|
|
|
** network changes
|
|
|
|
*** add keepalives to deal with NAT boxes
|
|
|
|
Some NAT boxes drop port mappings if the TCP connection looks idle for too
|
|
long (maybe 30 minutes?). Add application-level keepalives (dummy commands
|
|
sent from slave to master every 10 minutes) to appease the NAT box and keep
|
|
our connection alive. Enable this with --keepalive in the slave mktap
|
|
command line. Check the README for more details.
|
|
|
|
** UI changes
|
|
|
|
*** allow slaves to trigger any build that they host
|
|
|
|
Added an internal function to ask the buildmaster to start one of their
|
|
builds. Must be triggered with a debugger or manhole on the slave side for
|
|
now, will add a better UI later.
|
|
|
|
*** allow web page viewers to trigger any build
|
|
|
|
Added a button to the per-build page (linked by the build names on the third
|
|
row of the waterfall page) to allow viewers to manually trigger builds.
|
|
There is a field for them to indicate who they are and why they are
|
|
triggering the build. It is possible to abuse this, but for now the benefits
|
|
outweigh the damage that could be done (worst case, someone can make your
|
|
machine run builds continuously).
|
|
|
|
** generic buildprocess changes
|
|
|
|
*** don't queue multiple builds for offline slaves
|
|
|
|
If a slave is not online when a build is ready to run, that build is queued
|
|
so the slave will run it when it next connects. However, the buildmaster
|
|
used to queue every such build, so the poor slave machine would be subject
|
|
to tens or hundreds of builds in a row when they finally did come online.
|
|
The buildmaster has been changed to merge these multiple builds into a
|
|
single one.
|
|
|
|
*** bump ShellCommand default timeout to 20 minutes
|
|
|
|
Used for testing out the win32 twisted builder. I will probably revert this
|
|
in the next relese.
|
|
|
|
*** split args in ShellCommand ourselves instead of using /bin/sh
|
|
|
|
This should remove the need for /bin/sh on the slave side, improving the
|
|
chances that the buildslave can run on win32.
|
|
|
|
*** add configureEnv argument to Configure step, pass env dict to slave
|
|
|
|
Allows build processes to do things like 'CFLAGS=-O0 ./configure' without
|
|
using /bin/sh to set the environment variable
|
|
|
|
** Twisted buildprocess changes
|
|
|
|
*** warn instead of flunk the build when cReactor or qtreactor tests fail
|
|
|
|
These two always fail. For now, downgrade those failures to a warning
|
|
(orange box instead of red).
|
|
|
|
*** don't use 'clobber' on remote builds
|
|
|
|
Builds that run on remote machines (freebsd, OS-X) now use 'cvs update'
|
|
instead of clobbering their trees and doing a fresh checkout. The multiple
|
|
simultaneous CVS checkouts were causing a strain on Glyph's upstream
|
|
bandwidth.
|
|
|
|
*** use trial --testmodule instead of our own test-case-name grepper
|
|
|
|
The Twisted coding/testing convention has developers put 'test-case-name'
|
|
tags (emacs local variables, actually) in source files to indicate which
|
|
test cases should be run to exercise that code. Twisted's unit-test
|
|
framework just acquired an argument to look for these tags itself. Use that
|
|
instead of the extra FindUnitTestsForFiles build step we were doing before.
|
|
Removes a good bit of code from buildbot and into Twisted where it really
|
|
belongs.
|
|
|
|
|
|
* Release 0.3.2 (07 May 2003):
|
|
|
|
** packaging changes
|
|
|
|
*** fix major packaging bug: none of the buildbot/* subdirectories were
|
|
included in the 0.3.1 release. Sorry, I'm still figuring out distutils
|
|
here..
|
|
|
|
** internal changes
|
|
|
|
*** use pb.Cacheable to update Events in remote status client. much cleaner.
|
|
|
|
*** start to clean up BuildProcess->status.builder interface
|
|
|
|
** bug fixes
|
|
|
|
*** waterfall display was missing a <tr>, causing it to be misrendered in most
|
|
browsers (except the one I was testing it with, of course)
|
|
|
|
*** URL without trailing slash (when served in a twisted-web distributed
|
|
server, with a url like "http://twistedmatrix.com/~warner.twistd") should do
|
|
redirect to URL-with-trailing-slash, otherwise internal hrefs are broken.
|
|
|
|
*** remote status clients: forget RemoteReferences at shutdown, removes
|
|
warnings about "persisting Ephemerals"
|
|
|
|
** Twisted buildprocess updates:
|
|
|
|
*** match build process as of twisted-1.0.5
|
|
**** use python2.2 everywhere now that twisted rejects python2.1
|
|
**** look for test-result constants in multiple places
|
|
*** move experimental 'trial --jelly' code to separate module
|
|
*** add FreeBSD builder
|
|
*** catch rc!=0 in HLint step
|
|
*** remove RunUnitTestsRandomly, use randomly=1 parameter instead
|
|
*** parameterize ['twisted.test'] default test case to make subclassing easier
|
|
*** ignore internal distutils warnings in python2.3 builder
|
|
|
|
|
|
* Release 0.3.1 (29 Apr 2003):
