[users at bb.net] Buildbot failing to start

[Chris Spencer]

Yes, the buildbot.tac was generated. The contents are:

    import os

    from twisted.application import service
    from buildbot.master import BuildMaster

    basedir = '/usr/local/myproject/src/buildbot/master'
    rotateLength = 10000000
    maxRotatedFiles = 10
    configfile = 'master.cfg'

    # Default umask for server
    umask = None

    # if this is a relocatable tac file, get the directory containing the
TAC
    if basedir == '.':
        import os.path
        basedir = os.path.abspath(os.path.dirname(__file__))

    # note: this line is matched against to check that this is a buildmaster
    # directory; do not edit it.
    application = service.Application('buildmaster')
    from twisted.python.logfile import LogFile
    from twisted.python.log import ILogObserver, FileLogObserver
    logfile = LogFile.fromFullPath(os.path.join(basedir, "twistd.log"),
rotateLength=rotateLength,
                                    maxRotatedFiles=maxRotatedFiles)
    application.setComponent(ILogObserver, FileLogObserver(logfile).emit)

    m = BuildMaster(basedir, configfile, umask)
    m.setServiceParent(application)
    m.log_rotation.rotateLength = rotateLength
    m.log_rotation.maxRotatedFiles = maxRotatedFiles

I'm using Buildbot version 0.8.12.

When that didn't work, I tried using the version in the repo, which I
believe is 0.8.8-1.1 on Ubuntu 14. That didn't work either, but at least it
gave me an error message in its twistd.log complaining about it being
unable to import plugins. I'm assuming the master/slave code generated with
0.8.12 isn't compatible with 0.8.8.
