  very puzzling; I have backed up the broken objects store, can you
repush, please? I'm curious about how this could have happenned;
repo.or.cz now uses Git from latest next, which is a rather strange
coincidence. ;-) Or did any of the pushers do anything special about
pushin to the repository recently?

  Huge amount of objects is missing, the repository has only few loose
objects and

-rw-rw-r-- 1 repo 65657 1408 2008-07-10 18:56 pack-503b8e3e6f3a650c8bc37df88e8a9d7b6193c900.idx
-rw-rw-r-- 1 repo 65657 3364 2008-07-10 18:56 pack-503b8e3e6f3a650c8bc37df88e8a9d7b6193c900.pack

  (By the way, how do I list objects in a pack again? I keep forgetting
the trick...)

Aneesh, did you try repushing?  It looks like the objects store is
broken again.

Pasky, in case it helps, and for the benefit of Linux-ext4 folks, I
have a copy of my repository (which I last pushed to repo.or.cz around
noon US/Eastern yesterday) here:

     git://git.kernel.org/pub/scm/fs/ext2/ext4-patch-queue.git

My most recent HEAD is ec90e411; if anyone has something more recent,
they can send it to me via:

     git bundle create /tmp/to-send ec90e411

... and then e-mailing me as an attachment the resulting binary file
in /tmp/to-send.

I don't have permission to push to the repo. I can only pull.

Right, sorry, I forgot that you didn't have write access to the repo.

Pasky, my attempt to push is failing:

Can you completely zap the repository replace it with a freshly 
"git init"-ialized files, and I'll try repushing?

Thanks!!

  right, I have done that now. For anyone interested in the corrupted
repository, the backed up refs and objects directories are still in the
repository under the name *.broken, e.g. at

	http://repo.or.cz/r/ext4-patch-queue.git

I will try to analyze it myself later.
