Gitosis administration plugin
This plugin allows partial Gitosis administration from Trac. Gitosis is a tool which provides access control and remote management for hosted Git repositories. Users will be able to add their public SSH key in Gitosis in a new settings tab.
Admins will be able to set the location of the gitosis-admin repository and settings for the Git repository associated with Trac (requires GitPlugin).
If you have any issues, create a new ticket.

Before this plugin can work, you need a few things:
- a working git installation on the server running Trac
- SSH key pair without passphrase for the user running Trac
- access to a gitosis-admin repository
SSH key pair
Example on a RHEL server using Apache httpd :
# Create the key pair without passphrase mkdir /var/www/.ssh ssh-keygen -f /var/www/.ssh/id_rsa # Connect to the server hosting gitosis once to validate the server identity ssh -i /var/www/.ssh/id_rsa -o UserKnownHostsFile=/var/www/.ssh/known_hosts <git_user>@<git_server> # Give this directory to the user running Trac (here: apache) chown -Rh apache.apache /var/www/.ssh
Configure access to gitosis-admin
Simply add the previously generated public key in the file keydir/trac.pub and add the user trac in the gitosis-admin group members in the gitosis.conf file as for a standard gitosis admin. Then commit and push your changes. That should do it.
Configuration into Trac
You have to enable the plugin (and restart Trac) with this parameter in trac.ini:
[components] tracgitosis.* = enabled
Next, in the Admin panel, you'll see two pages in a new Trac Gitosis section:
- Admin Settings
- Repository Settings
In the Admin Settings, you must give gitosis-admin access parameters before you can actually use this plugin:
|Admin Repository Name||gitosis-admin||the name of the gitosis administration special repository|
|User||git||System username for access on the gitosis repositories|
|Server||localhost||Server hosting gitosis repositories|
Save changes and enjoy the Repository Settings (for admins only) and the gitosis SSH public key in all users preferences.
When accessing either Repository Settings or gitosis SSH public key for the first time, Trac clones the gitosis-admin repository at the root of the trac project.
Then, each time these pages are displayed, the repository is pulled in order to read current settings and public keys. When you press Save changes, the repository is pulled again, settings are written into gitosis.conf, public key is written into keydir/<user>.pub, changes are committed and pushed to the main admin repository.
The gitosis file is overwritten each time setting are saved in Trac using a modified ConfigParser Python class. The [gitosis] section will be written first. All other sections will be written in a sorted way. In each section, the parameters are written the same sorted way.
In short, this means:
- sections and parameters will be moved if they were not sorted in the original file
- all comments will be lost, because I don't know were to write them after section and/or parameters moved
