Hi,
At work we use SVN. To deal with this I mirror the svn repo with
git-svn and have a cron job that runs git svn rebase every hour, and
then I rebase from that git repo.
Unfortunately, on the computer that runs the cron job, /home ran out
of space. After making more space and deleting the
svn/trunk/.rev_map, my 'git svn rebase' dies with a
> git svn rebase
Rebuilding .git/svn/trunk/.rev_map.4279b43a-dd95-8640-b069-b0d2992e4ff2 ...
error: Could not read 3d4c2b0225e7605a7e2a38ffc44dcb888589f4ce

So I look for corruption with

Thankfully, I have copies of the repo and this object (3d4c2b) in
other location and that passes git-fsck. Strangely, it is a commit
object from about 18 month ago and should have been in a pack for a
long time, so maybe running out of disk space was not the cause.
I would rather not copy the whole good repo back to the one that ran
out of space because it's multiple gigs. My plan is to just explode
the bad pack on of the corrupted repo, explode good pack and then,
copy the corrupted object back. So my question is how do I tell which
pack contains that object? (I would rather not explode all the packs
because of the repo size.) Is there a way to extract a single object
from a pack without exploding the whole pack?
git is version 1.6.4 on CentOS 5.3
Thanks,
Tarmigan
