git-http-push (git v1.5) problems with DAVLockDB on reiserfs FS

git-http-push (git v1.5) problems with DAVLockDB on reiserfs FS

[Fabien]

Hi,

I encountered many problems when using a git repository served over
apache/dav on ubuntu 8.04LTS
* versions in use on server:
- kernel 2.6.24
- apache 2.2.8
- git version 1.5.4.3 or 1.6.6.2 (doesn't change anything on server side)

* versions in use on clients
git 1.5.4.3 => causes problem
git 1.6.6.2 => is ok.


With client 1.5, when pushing more than one commit, it fails with this
error:

$ git push origin master
Fetching remote heads...
  refs/
  refs/tags/
  refs/heads/
updating 'refs/heads/master'
  from ad49aa06f145c5176f230744eb047f5f132361ab

    done
Updating remote server info
error: http-push died with strange error
error: failed to push some refs to

leaving the repository in the middle of the push which is really bad:
$ git fsck
bad sha1 file:
./objects/1d/881d1c352047547135810123fdc13fb4f8e1db_88cb4b13-a549-445f-b0f1-79aaf746129e

I finally noticed that this problem only occurs when I have the
DAVLockDB file on a reiserfs partition. If I move it on ext3, it's ok.
Weird...

Does somebody know which commit version change this behavior between 1.5
and 1.6 ?

although nothing might have changed on the server-side, git does a lot
of server-side operations via WebDAV, like locking, moving files, etc.

why not just use git 1.6?

Yes, I forgot to say the problem is related to locking problems on the
server side :
Could not LOCK /git-tests/project1.git/info/refs due to a failed
precondition (e.g. other locks)

This is why I tested another file system, because I already had problems
in the past with reiserfs and locking :)

Yes, but I have to tell that to around 100 contributors ;-)
I plan to use a rule in apache to deny access to old versions of git...
