This patch is not actually for transferring objects which are in pack
files in the source, but for transferring a group of objects as a pack
file. It does, however, read the source side with git-pack-objects to
generate the content to send, so it would, I guess, fix the problem for
the case where it decides to use a pack to transfer.
The real fix is to go through the pull methods (local-pull and
ssh-pull; http-pull presumably won't be encountering pack files yet) and
make them do appropriate things with pack files.
One thing that is in the patch is a change to the comment, specifying
that fetch() could also get other objects in addition to the one
specified, if there's some reason to think this is a good idea; the fix
for local-pull is probably to link/symlink/copy the pack file if the
object is in one.
For ssh-pull, serve_object in ssh-push needs to be taught how to extract
an object from a pack file and send it.
However, there's a bug in pull.c, covering up a terrible performance
issue: it doesn't actually make sure you have all the parent of a commit
that you had when it checked (due to not having a way of caching the
result of checking this, which would require you to put the entire
repository through cache each time you pull). This would mean that, if you
have a pack that references something outside of it, you won't get
everything with my proposal above.
I should be able to spend some time on these issues over the weekend.
