[nico-trackhack-git@…]

I installed trac & trac-git from debian lenny: 0.11 of trac:

ii trac 0.11-3 Enhanced wiki and issue tracking system for ii trac-git 0.0.20080710-1 Git version control backend for Trac

I did GIT_DIR=trac/g1 git init and git push trac master:refs/heads/master to populate the git-repo. trac options:

[git] cached_repository = false git_bin = /usr/bin/git persistent_cache = false shortrev_len = 7

[trac] repository_dir = /home/nicosc/trac/g1/ repository_type = git

nicosc@ikdesk1:~/trac/g1$ git --version git version 1.5.6.5

I get this error:

Any idea what I did wrong?

I get something comparable whenever it tries to resolve a rev:

lyndir tracext # git --version

Using Trac 0.11.2.1

As a result, nothing from GIT is available anymore.

Note: This is after having patched GitPlugin to fix this issue: #4227

[lhunath]

Uhm, I take that back. After cleaning up the patch I submitted for #4227 my issue went away.

In case the patch difference is somehow useful (if this issue is even related to what I was struggling with) I will commit the cleaned up patch (which does fix #4227) as a separate file.

Have you tried creating some entries in git repo ? If it is null sometimes it gives this assertion.

Looks like a duplicate of #4139
