[Buildbot-devel] Still have problems with schedulers passing wrongbranches

[Gavin]

I'm not sure using branch=None is helping matters.

Im also not sure of your exact svn setup. Considering your BaseURL
exception, perhaps you should try using that in all your factories.

Here is an example of what we use.

c['schedulers'].append(AnyBranchScheduler(name="on-rat-commit",
                         branches=["incubator/rat/main/trunk"],
                         treeStableTimer=2,
                         builderNames=["rat_trunk"]))

#builders

f2 = factory.BuildFactory()
f2.addStep(SVN(
    mode="clobber",
    baseURL="http://svn.apache.org/repos/asf/",
    defaultBranch="incubator/rat/main/trunk",
))

Note that if you go and browse http://svn.apache.org/repos/asf/ you will see
100+ projects there, I have one Buildbot master managing all of the projects
that want to use it and use a modified svn post-commit hook to send the
branch info to buildbot (via svn_buildbot.py), all other non-participating
branches are ignored. Probably straying off-topic there, but anyway, perhaps
using baseURL combined with branches/defaultBranch might put you on the
right track.
