Subject: auto packing with simultaneous pushes: "error: Could not stat 'objects/[…]/[…]'"
Date: Wed, 23 Jan 2013 18:50:38 -0500 [thread overview]
Message-ID: <CADcu=0jCkNr6J_-iiKp00aSXHPf=+QV6oFvFHUZ_uc02JTaCbQ@mail.gmail.com> (raw)
my coworker and i just pushed some commits seconds apart from each
other. both of our pushes triggered a server-side auto pack
(presumably as part of ``receive-pack``, as a result of the setting
``receive.autogc = true``). each auto pack produced multiple errors
of the form ``error: Could not stat 'objects/[…]/[…]'``. there
appears to be no overlap between the two auto packs' lists of failed
object hashes.
my suspicion is that the two auto pack processes each generated a list
of objects to pack, then proceeded to pack them, removing the
corresponding files as they went along. as each one encountered an
entry in its list that was previously handled by the other process, it
found that it was unable to stat the corresponding file because it had
been removed by the other process.
my suggestion is that an auto pack should lock the repository,
preventing at least other auto packs (and perhaps other operations)
from running until it is finished. alternatively, the auto pack can
skip over objects that were already packed by another process;
however, i imagine this would be much less efficient if done
correctly.
here is the console output from my push:
$ git push
