[Buildbot-devel] one master - multiple projects

I've accomplished just this.
First, I hacked the svn_buildbot.py script to report the repository
name in the changes
instead of trunk/foo.txt
then, I subclassed the Scheduler class like so:
RCS file: /cvsroot/buildbot/buildbot/buildbot/scheduler.py,v
retrieving revision 1.15
diff -U5 -r1.15 scheduler.py
--- buildbot/scheduler.py 12 Mar 2006 11:28:04 -0000 1.15
+++ buildbot/scheduler.py 4 May 2006 17:34:08 -0000

+ log.msg("%s: change is not important, discarding %s" % (self,
"""This Scheduler will handle changes on a variety of branches.
accumulate Changes for each branch separately. It works by
separate Scheduler for each new branch it sees."""
and lastly, I did the following to my master.cfg:
thisMaster_projects = [
def isChangeImportant(project_name, change):
project_name_expr = re.compile(project_name)
for file in change.files:
if project_name_expr.match(file) != None:
return lambda change: isChangeImportant(project_name, change)
#fix this to get it's list from the same place as the builders
for project in thisMaster_projects:
(make_importanceTest(project + "/trunk"))
then set up the builders for each of those projects with the same name
and you should be good.
The krux was OnlyImportantScheduler and the closure-based trick for
generating importance tests on the fly.
Not re.compiling every time is also possible by moving the regular
expression object you're matching against
into the closure.
