Hello,
I have set up a buildbot for my first time (you do cool things !) and I
have fallen into a nasty bug.
I'm using buidlbot (slave and master) on Debian squeeze with mercurial:
{{{
(chroot)r...@kalessin:/tmp# buildbot --version
Buildbot version: 0.7.11p3
Twisted version: 9.0.0
(chroot)r...@kalessin:/tmp# hg --version
Mercurial Distributed SCM (version 1.4.1)

PURPOSE.
(chroot)r...@kalessin:/tmp#
}}}
Whenever a new build was launched the slave started an infinite loop. The
reason was here :
http://github.com/djmitche/buildbot/blob/master/buildbot/slave/commands.py#L2915
You compare two directories paths, but done this way /foo/bar and
/foo/bar/ appears to be differents. In my case when the condition was
true, the slave restarted a complete checkout of the code, falling again
in the condition, and again, and again, and again...
I have resolved the problem, by setting my repourl in my master.cfg
without the ending slash :
{{{
#!python
from buildbot.process import factory
from buildbot.steps.source import Mercurial
from buildbot.steps.shell import Compile, Configure, Test
f1 = factory.BuildFactory()
f1.addStep(Mercurial(repourl="/tmp/zia"))
f1.addStep(Configure(command=["cmake", "."])) # do not use configure
f1.addStep(Compile()) # make all
f1.addStep(Test()) # make test
}}}
A more robust way to compare directories paths should be used.
Please, find the log from both the slave and the master attached with this
ticket. (due to the loop I have truncated them).
Best Regards
