[devel at bb.net] [users at bb.net] py3 master <==> py2 worker, problem

[Pierre Tardy]

'slave-config' is an old marker which is only valid for eight workers.
https://github.com/buildbot/buildbot/blob/master/master/buildbot/process/remotecommand.py#L404

it is set here:
            if self.step.workerVersionIsOlderThan("shell", "3.0"):
                # Old worker default of usePTY is to use
worker-configuration.
                self.args['usePTY'] = "slave-config"

but it shouldn't as you are using a nine worker. I think maybe
workerVersionIsOlderThan may not work because of nativeString use.
