and I have also changed the repository.git to 777 , and also added trac-post-receive-hook-0.12-new-commits-from-all-branches-with-logfile.py
as directed in http://trac-hacks.org/wiki/GitPlugin#post-receive hook scripts, i m on
trac-admin 1.0.1 and git version 1.7.10.4 … but i m experiencing
Error: No such changeset No changeset None in the repository
when i try to browse the repository.
Please help - proper detailed way to solve it.

If your git repository has no commits, that is a correct behavior in Trac. Otherwise, git command might exit with some errors.
Could you please apply ticket11220-debug-git-logging.diff and confirm your trac.log when visiting "Browse source"?
After the patch, the following is logging.

I tried to add a simple file and then tried commit, but the same stuff is shown up..
Later applied the patch in the file and ran the Browse Source but same error message comes up. And the log shows this..

My doubt is, am i missing or need different
- Different chmod and chown setting for the trac/git folder
- Am i placing the post-commit file properly.
- I have not set any admin/user for my trac environment, could it be the problem.
sorry for the noisy log file i added.
Thanks …

Hi, I'm experiencing the exact same problem. Trac 1.0.1, Debian 7.1 (wheezy), git 1.7.10.4 and using Gitolite to manage repositories.
After applying the diff for extra logging I get the following in Trac log when trying to access a test repository:

Compare the following two invocations on the machine in question:
www-data@boltian:~$ git --git-dir=/home/git/repositories/testing.git branch fatal: Failed to resolve HEAD as a valid ref.
The above corresponds to the error we are seeing in the Trac log. If I do the same thing as the git user:
git@boltian:~$ git --git-dir=/home/git/repositories/testing.git branch * master
Checking permissions (try eg. find .) reveals that some files cannot be read by the trac user. In other words, "Failed to resolve HEAD as a valid ref." is git-speak for "Permission denied".
Following the instructions at https://github.com/boldprogressives/trac-GitolitePlugin for setting up a shared group used by both gitolite and trac fixes this problem for me.
Perhaps the Git support in trac could be improved to detect these kinds of errors and fail with a suitable hint to the user? Or at least this could be prominently documented somewhere.

Great! Thanks for the investigating.

Yeah, Trac must be able to directly access the git repository.

Good idea, I worked in [1529a510/jomae.git]. If it isn't readable a repository, log the following.

Can u guys please share me a proper steps to make my trac-git work. Using the gitolite would also do the trick, thou as of now i am not using the gitolite. Am just a trac and git newbie. Thanks for the infos.

Let me also try to follow the gitolite way https://github.com/boldprogressives/trac-GitolitePlugin for the time being , let me check this route too… thanks

Hi guys , finally my stuffs are working with gitolite and its a great experience to set it right. Thanks to u guys… just added www-data and git on a group and changed the repository to 777 and also added a user 'git' with sudo rights. Also i changed to trac :trac-admin 1.0.1.
did trac-admin /var/www/trac repository resync "*" and it worked.. :)
cheers to all..

Can't synchronize with repository "(default)" (No changeset f5c1909d7023448f3aee68c25cd7a193f63ea196 in the repository). Look in the Trac log for more information.

That is an InstallationIssue. Please ask for support on Trac usage on the MailingList or IrcChannel.

I realise - this steps that let to my latest prob is
- I have my repository changed to 777
- then i edited a file, committed the file and then
git push - Then I did
sudo trac-admin /var/www/trac repository resync "*"

The problem is resolved, in case this could be use to ppl in trouble like me,
after using gitolite, i switched to my git user, and then vim .gitolite.rc and changed the UMASK to 0027 ..
and it works out - thanks
