[Buildbot-devel] buildbot 0.8.1rc2 master not starting completely

[Andy Howell]

John,

	Thanks. That pointed me in the right direction. Turns out it was my own stupidity. I
wanted the master in '~/Master', but didn't specify the basedir. I made the '~/Master'
directory an moved the files in there. What is didn't notice is the line:

basedir = r'/home/buildbot/'

in buildbot.tac. I added Master to that and it started up just fine. d'oh.

Thanks,

	Andy

I am not too sure what effect being in the debugger has to the twisted internals, but my guess is that it blocks the entire application until the debugger finishes.  I also found that the logging prefix is still applied to every pdb line which gave me sample output like:
