[Buildbot-devel] Any way to know if checkconfig is being run?

[Richard O'Grady]

I just call this function:

def StartXYZServer():
  try:
    reactor.listenTCP(
        XYZServer.DEFAULT_PORT, pb.PBServerFactory(XYZServer()))
  except error.CannotListenError:
    # Probably buildbot is already running with this port open.
    # This happens e.g. during checkconfig as the config file is executed
    # with the server already running.
    pass

This PB server is unrelated to buildbot but it's convenient for us to have
it live and die with it.
I thought about looking in sys.argv but figured maybe there was a more
idiomatic way.
The idea of having a fake change source is neat, thanks.
