[Buildbot-devel] Problem with 0.7.10

[René Müller]

Hi,

I upgraded buildbot to 0.7.10 and now I get this log:

I tried very much different things:
 - python 2.5 and twisted 8.1
 - python 2.5 and twisted 8.2
 - my old buildmaster and slave (from 0.7.9)
 - new buildmaster and new slave

The build only consists of this (master.cfg.sample):

from buildbot.process import factory
from buildbot.steps.source import SVN

f1 = factory.BuildFactory()
f1.addStep(SVN(svnurl="https://xxxxx",\
               mode="clobber",\
               username="xxxx",\
               password="xxxx"))

b1 = {'name': "testbuild",
      'slavename': "Test-Buildslave",
      'builddir': "testbuild",
      'factory': f1,
      }
c['builders'] = [b1]


Now I force the build, the svn-step works (reported as success and a green color in the waterfall), but the build is marked "exception". When I add more steps, the build stops after the svn-step.

Can anybody give me a hint where to start? I already searched for an solution for 2 days, but I can't get it working. When I downgrade to 0.7.9 everything is fine.

Greetings,
René
