Sorry, my WikiFormatting got eaten.

I originally submitted this at ​http://trac.edgewall.org/ticket/10474 which is formatted properly.

[anonymous]

Which version of trac-git-plugin did you use?

[anonymous]

easy_install http://github.com/hvr/trac-git-plugin/tarball/master as described on GitPlugin.

[adamculp@…]

I have the same issue. Installed trac and git-trac from Ubuntu repos. Set up trac.ini file as follows:

repository_dir = /path/to/repos/.git
repository_type = git
tracrpc.* = enabled
tracext.git.* = enabled
cached_repository = false
persistent_cache = false
shortrev_len = 6
wiki_shortrev_len = 7
git_bin = /usr/bin/git
git_fs_encoding = utf-8
trac_user_rlookup = false
use_committer_id = true
use_committer_time = false

I have also the same issue when using trac-git with Ubuntu Oneiric.

[lorinh@…]

It looks like the trac-git package that ships with Ubuntu Oneiric is broken, removing it and installing using easy_install from github fixed the problem for me.

[anonymous]

I had the same problem in Ubuntu Natty, then removed and installed at github and the problem has changed, now the problem is:

Note: I'm using Trac1.0. I migrated from version 0.12 to 1.0 today.

I'm very sorry! The problem was actually just the name of the repository that pyECF typed instead pyecf.

[repositories]
.alias = pyecf
pyecf.description = This is the ''main'' project pyECF.
pyecf.dir = /opt/git/pyECF.git
pyecf.hidden = true
pyecf.type = git

Now I am a happy user Trac today that migrated from version 0.12 to 1.0.

So you are using the optional component that is distributed with Trac, rather than this plugin?

p.s. I cleaned up the formatting in your comments. You may want to give ​t:WikiFormatting a quick read ;)

I installed the plugin for trac-git Github. The trac-git on Ubuntu Natty is broken.

easy_install http://github.com/hvr/trac-git-plugin/tarball/master

Also enabled in my trac.ini:

tracopt.versioncontrol.git.* = enabled

[Ryan J Ollos]

What I was trying to describe to you earlier is that ​t:TracGit is part of the Trac project starting with Trac 1.0. Rather than installing that egg, you can just enable the plugin via the webadmin panel, or editing trac.ini. The reason I suggest this is that the version in the Trac core was brought in from http://github.com/hvr/trac-git-plugin/tarball/master, and you'll find that there have been bugfixes and will be better support going forward (see ​t:TracGit#History).

Anway, if you are interested in going that route, you should read the ​t:TracGit page.

I understand! In reality when I installed trac-git I was still using version 0.12.

In Trac1.0, so it is recommended to remove the "eggs" to trac-git?

And then let enabled native support:

tracopt.versioncontrol.git.* = enabled

[Ryan J Ollos]

Yeah, you should remove the egg, enable as you describe and then configure per the instructions at ​t:TracGit.

Thank you very much.
