Wierd git over http behaviour

Hi,

We have a git tree that accesses fine via the git protocol, however I have also opened up http support for it as some of our users are behind git-unfriendly corporate firewalls.

I know http transport is not encouraged, but not much I can do about that.

Strange thing is, when doing an http fetch of said tree, it gets no updates to the tree later than about Jan 13 this year, even though the tree itself has many, many commits since then (its origin is Linus's tree and we pull regularly). Heads created later than that date are also not visible (doing git branch -a) in the clone pulled over http. Clones made using git: are fine.

Anything I can look for in the .git repo on the server, permissions or similar that might be relevant? It's almost like there's a single commit in there that somehow is making the http fetch puke. If you browse the http tree with a web browser, it's all there as expected.

For reference here are the URLs:

git://developer.petalogix.cmo/linux-2.6-microblaze

http://developer.petalogix.com/git2/linux-2.6-microblaze

Initially the http reference was a symlink on the server to the actual git tree, but I also tried just rsync'ing it across to /var/www/html/git2 to make sure it wasn't the symlink breaking things - no change.

Am I misunderstanding something or is this just flakey behaviour of the http protocol support?

Thanks,

John
