Slave backward compatibility is not documented

Reported by: techtonik Owned by:
Priority: patches-accepted Milestone: 0.8.+
Version: 0.8.7p1 Keywords: docs


I have a standard Debian squeeze installation as a buildbot slave with:

Buildbot version: 0.7.12
Twisted version: 10.1.0
Python 2.6.6

and running 0.8.7p1 as a buildbot server.

The build fails with the following trace:

Traceback (most recent call last):
  File "/home/sconsbuildbot/buildbot-master/bbenv_087/lib/python2.7/site-packages/twisted/internet/defer.py", line 368, in callback

    return g.throw(RemoteError(self.type, self.value, self.traceback))

    updatable = yield self._sourcedirIsUpdatable()
twisted.spread.pb.RemoteError: unrecognized SlaveCommand 'stat'

I'm puzzled about python2.7 directory name and whether it is buildbot bug with Python versions or backward compatibility issue. It would be nice if backward compatibility was properly documented.

  • Priority changed from major to patches-accepted
  • Type changed from undecided to enhancement
  • Milestone changed from undecided to 0.8.+

The new master-side steps don't work with old buildslaves. I suspect the cut-off is 0.8.5.

If somebody were to research and document the requirements, that would certainly be accepted.

(Note: The traceback is from the master)
