NoSuchRevision when pushing to RemoteBranch

[Andrew Bennetts]

I just got this:

NoSuchRevision: RemoteBranch(bzr+ssh://people.ubuntu.com/home/andrew/public_html/bzr/suspend-write-group/) has no revision <email address hidden>

bzr 1.13dev on python 2.5.2 (linux2)
arguments: ['/home/andrew/code/bzr/bzr', '-Dhpss', 'push']

The problem seems to be that the client isn't falling back to pre-1.13 logic when the Repository.insert_stream RPC is unavailable:

...
24.011 hpss call w/body stream: ('Repository.insert_stream', 'home/andrew/public_html/bzr/')
26.550 result: ('UnknownMethod', 'Repository.insert_stream')
26.551 hpss call: 'delete', '/home/andrew/public_html/bzr/.bzr/repository/upload/e7kiy5xz8xwglrmhbndo.pack'
26.551 (to bzr+ssh://people.ubuntu.com/home/andrew/public_html/bzr/suspend-write-group/)
26.904 result: ('ok',)
26.905 hpss call: 'PackRepository.autopack', 'home/andrew/public_html/bzr/'
26.905 (to bzr+ssh://people.ubuntu.com/home/andrew/public_html/bzr/suspend-write-group/)
27.274 result: ('ok',)

(Then just a delete, get, get_parent_map, and unlock. Then the traceback happens.)

Is this a stacked branch or non stacked?

Workaround getting tested at the moment.

[Andrew Bennetts (spiv)]

Robert has landed a fix, and it works for me.
