Trac Release: 0.11, same 0.12

[Steffen Hoffmann]

What happend? You didn't select the proper component, and since you're not a registered user with this site you're not allowed to change it afterwards.

Anyway you should still provide more details regarding your configuration (trac.ini, etc.) to give us something to help you. And putting in your email address will help you much with tracking the changes of your ticket.

I have the same problem with Trac 0.12.1, GitPlugin 0.12 r7757 and python-subversion 1.6.6dfsg-2ubuntu1. From the log file:

2010-10-14 17:35:46,836 Trac[PyGIT] DEBUG: requested PyGIT.Storage instance 28793744 for '/home/akaihola/test.git'
2010-10-14 17:35:46,836 Trac[git_fs] INFO: enabled CachedRepository for '/home/akaihola/test.git'
2010-10-14 17:35:46,837 Trac[PyGIT] ERROR: GIT control files missing in '/home/akaihola/trac/git'
2010-10-14 17:35:46,837 Trac[chrome] ERROR: Error with navigation contributor BrowserModule: GitError: GIT control files not found, maybe wrong directory?

The directory /home/akaihola/test.git is a bare repository created with git init --bare, and I've pushed several commits into it. All directories and files are owned by me and I run tracd as myself.

Modifications I've made to the default trac.ini:

[trac]
repository_dir = /home/akaihola/test.git
repository_type = git

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

[components]
tracext.git.* = enabled

I've also tried without the settings in the [git] section. Same error.

[Antti Kaihola]

This might help: I ran tracd in the Python debugger, and evaluated these at trac/versioncontrol/api.py:526:

ipdb> import pprint;pprint.pprint(self.get_all_repositories())
{'': {'dir': u'/home/akaihola/repos/test.git',
      'id': 2,
      'name': ''},
 u'/home/akaihola/repos/test': {u'dir': u'/home/akaihola/trac/git',
                                'id': 1,
                                u'name': u'/home/akaihola/repos/test',
                                u'type': u''}}
ipdb> self

Solved: the trac-admin repository add command adds invalid entries into the database. Fixed them directly with sqlite3 and all works correctly.

[anonymous]

What exactly was your trac-admin repository add command in the first place btw?

[Antti Kaihola]

I tried to reproduce the problem, without success. I was messing around with both the [trac]/repository_dir and [trac]/repository_type settings and the trac-admin test repository add test /home/akaihola/test.git git or similar commands, and the repository table ended up containing entries with strange paths.

It's confusing that for some reason I ended up having the key repository_dir with a value like git:/home/akaihola/test.git instead of dir and /home/akaihola/test.git in the repository table. It looks like this has something to do with specifying the repository in trac.ini.

Sorry for not being able to reproduce exactly what happened before.

[anonymous]

thx for trying to reproduce :-)

do you remember if you could have fixed that problem also by using the repository section within the trac admin pages, instead of having to directly fix the sqlite database?

[dan@…]

I had this same error... looking closely at my trac.ini, I found an error in the path to the Git repo. So, the 'maybe wrong directory' hint was right on! Once fixed & resynced, all was fine!

[sai.giridhar@…]

I recently had done two installation of the git plugin and i have come across this error on both of them. I have solved it by doing

sudo chown -R git:www-data git-repository

and make sure that the group user has a read access to the repository. Hope this helps :)

[anonymous]

Thanks for the permissions hint - I've moved my repositories during Lenny to Squeeze upgrade, and lost the group permission, causing this error to appear.

[anonymous]

Replying to sai.giridhar@inso.tuwien.ac.at:

sudo chown -R git:www-data git-repository

In case of usage with gitolite: remember to setup a post receive hook. By default the ownership changes with each commit back to git:git.

[anonymous]

for me, it's really because I was not using a bare repo/not pointing to .git.

[track-hacks@…]

One more hint: If you are running trac with apache and mod-python, remember to restart apache after adding the apache user (www-data on debian/ubuntu) to a group with permissions to your git repository. This is not needed if the apache user is the actual owner of the repository, only if it is a group member.

[Walkman]

I had the same issue. Deleting and readding the repository in Trac admin solved the issue. I did that based on comment:6, thank you!

[Ryan J Ollos]

At least for the case of non-bare repositories, a similar issue was fixed in ​trac:#11297. For a non-bare repository, the Repository path must point to a .git directory (at least prior to ​[trac 12225], which using ​TracGit that is part of the Trac core). There is also ​trac:#11371, which might be responsible for some issues.

[Ryan J Ollos]

GitPlugin is deprecated. Please upgrade to Trac 1.0 and use ​TracGit.
