gbp-pull from the git-buildpackage uploaded to unstable last week has
an unpleasant effect (the version in testing is not affected). It
tends to fall asleep under certain circumstances:
The circumstances or: How to reproduce:
1) a repo with a remote that uses ssh
2) ssh with sockets [0]
3) calling gbp-pull when the socket for the repo's server doesn't
exist yet
[0] e.g.
Host *
ControlPath ~/.ssh/sock/%r@%h:%p
ControlMaster auto
ControlPersist 60
In this combination, gbp-pull waits for ControlPersist seconds.
(This does not happen with non-ssh URLs or when the socket exists due
to an earlier call to git or ssh or gbp-pull).
The problem seems to be caused by commit 8541450; some poking around
with ipython and randomly changing the code seems to suggest that the
problem is in the subprocess.Popen/communicate call in
gbp/git/repository.py line 146, more precisely in the stderr
handling; with the current code, the gbp-pull waits until the
persistent ssh socket gets killed (in select.poll()). If stderr is
not set to a PIPE then this waiting doesn't happen. It looks like
Popen waits for the ssh socket ...
Unfortunately I have no idea how to fix this, and capturing stderr
doesn't sound like a bad idea :)
PS: http://bugs.python.org/issue4216 sounds similar.
Cheers,
gregor
