[Buildbot-devel] Perforce (P4) commit trigger

[Tony Walker]

Hi,

Thanks for the information. Ok, so I have set up a p4poller in the 
master config file like this:

p4_source = p4poller.P4Source(p4port="192.168.0.80:1666", 
p4user="general",p4client="buildmaster", 
p4base="//depot/Dev/Projects/Sublines/stage_a/...", 
p4bin="/usr/local/bin/p4",pollinterval=300)

and a scheduler to suit:

c['schedulers'].append(Scheduler(name="all", branch="stage_a", 
treeStableTimer=2*60, builderNames=["builder_a","builder_b"]))


What I have noticed from the log on the buildmaster side is that it now 
seems to be polling the perforce repository, which is great, and it gets 
a submitted change. However, it doesn't seem to kick off a build 'two 
minutes' later. I noticed that in the 'scheduler.py' file, two branches 
are getting compared, change.branch and self.branch. Now, 
self.branch=stage_a (which is correct), but change.branch=None  ?? So it 
won't build. So my question is, where is this supposed to be set? I can 
assume at this point that p4poller.py is extracting information and 
setting these variables up, but missing the branch, is this correct? Any 
ideas would be greatly appreciated.

Thanks,

Tony.
