Comment 4 for bug 403857

Hi,

I believe the original bug report was slightly wrong, re-opening as I think it is
still an issue.

It should have been

   bzr export localname bzr+ssh://bazaar.launchpad.net/~oubiwann/project/branch/subdir
   bzr: ERROR: Permission denied: "Cannot create 'subdir'. Only Bazaar branches are allowed."

Consider

   bzr ls lp:~bzr/bzr/trunk/bzrlib/
   bzr: ERROR: Permission denied: "Cannot create 'bzrlib'. Only Bazaar branches are allowed."

Traceback (most recent call last):
  File "/home/jw2328/devel/bzr/bzr.dev/bzrlib/commands.py", line 835, in exception_to_return_code

    return remote.RemoteBzrDir(transport, self)

    response = self._call('BzrDir.open', path)
  File "/home/jw2328/devel/bzr/bzr.dev/bzrlib/remote.py", line 56, in _call

  File "/home/jw2328/devel/bzr/bzr.dev/bzrlib/remote.py", line 2668, in _translate_error
    raise errors.PermissionDenied(path, extra=extra)

so calling BzrDir.open on a path that is "under" a branch is rejected by LP.
Presumably if it just says "not found" to the open request then bzr would continue
and open the containing branch.

I'm not sure how this would affect the ability to reject pushes to arbitrary locations
though.

Thanks,

James
