trac-GitolitePlugin 0.3.1

Two-way integration of Trac and Gitolite
trac-GitolitePlugin is a Trac plugin that provides two-way integration with gitolite: https://github.com/sitaramc/gitolite.

1. Users who don't have read access to a repository in Gitolite will be blocked from viewing that repository in Trac's web browser
2. Trac admins may manage users' gitolite-based repository permissions through the Trac web interface
3. Trac admins may add and remove users' SSH public keys through the Trac web interface to control access to the gitolite system
4. Trac admins may use a "Create New Repository" feature to initialize an empty gitolite repository through the Trac web interface

Installation

Overview

1. Install Trac and Gitolite on the same server.
2. Ensure that the system user running the Trac process has filesystem read access to all gitolite repositories in the present and future. The simplest way to do this is to run Trac as the gitolite user; the more correct way is to add Trac to the gitolite user's primary group and set UMASK=>0027 in .gitolite.rc as well as running chmod to fix up permissions on the already-created files.
3. Ensure that the system user running the Trac process can clone and push the gitolite-admin repository, by setting up an SSH keypair for the Trac user, adding that public key to gitolite-admin/keydir and adding RW+ (or just RW) permissions to the corresponding user in gitolite-admin/conf/gitolite.conf for "repo gitolite-admin".
4. Tell Trac about the existence of the gitolite-admin repository by running a command like trac-admin repository add gitolite-admin $GITOLITE_HOME/repositories/gitolite-admin.git git
5. Install the trac_gitolite plugin, enable its components in trac.ini and prepend "GitolitePermissionPolicy" to your site's trac.ini permission_policies settings.

Detailed Instructions

First, install both Trac and Gitolite in the standard ways. They must be installed on the same server.

You will need to ensure that Trac has the necessary read access to the filesystem directory that contains your gitolite repositories. If Trac is running as user "wsgi" and gitolite has been installed to run as user "git" with a homedir /home/git/ you will probably want to run a command on your server like this:

sudo usermod -a -G git wsgi
sudo chmod -R g+rX /home/git/repositories/


You will also need to ensure that Trac can continue to read all needed files over time. One way to do this is to set the UMASK setting in .gitolite.rc to 0027. Another way would be to set the repository configuration core.sharedRepository = group in all existing and new repositories (including gitolite-admin) using a repository template.

Now Trac will be able to read from your gitolite repositories using its standard repository features.

You then need to add the gitolite-admin repository itself to Trac. This will allow Trac to read configuration files directly from the gitolite-admin repository using its own version-control APIs. Do this with a command line:

trac-admin /path/to/env/ repository add gitolite-admin /home/git/repositories/gitolite-admin.git git

From now on, to add an existing gitolite repository named "my-first-repo" to your Trac system, you would add a Trac git repository named "my-first-repo" with directory /home/git/repositories/my-first-repo.git through Trac's standard administrative web interface, shell scripts, or configuration files.

Next, you will need to grant the Trac system user read and write permissions on the gitolite-admin repository through gitolite itself. This is how Trac will write changes to your Gitolite system (web-based user, permission and repository management) -- it will clone the gitolite-admin repo, write changes, commit and push them back to the server.

To do this -- again supposing that Trac is running as user "wsgi" -- you will run commands on your server like this:

sudo su wsgi
ssh-keygen
exit
cd /tmp/
git clone git@localhost:gitolite-admin.git
cd /tmp/gitolite-admin/
echo "repo gitolite-admin
 RW+ = wsgi" >> ./conf/gitolite.conf
sudo cp ~wsgi/.ssh/id_rsa.pub ./keydir/wsgi.pub
git add keydir/wsgi.pub conf/gitolite.conf
git commit -m "configuring trac_gitolite permissions"
git push


Finally, enable the trac_gitolite components in trac.ini for your site:

[components]
trac_gitolite.* = enabled


This will add three new panels to the "Version Control" section in the Trac Admin. To additionally enable the permission policy, add to your trac.ini:

[trac]
permission_policies = GitolitePermissionPolicy, AuthzPolicy,
 DefaultPermissionPolicy, LegacyAttachmentPolicy


Configuration

Sensible defaults are provided that should work for most typical installations of Trac and Gitolite. The following trac.ini options (all in a [trac-gitolite] section) can be modified if necessary:

- admin_reponame: defaults to gitolite-admin; this is the name in trac of the gitolite-admin repository
- admin_real_reponame: defaults to gitolite-admin; this is the name in gitolite of the gitolite-admin repository
- admin_ssh_path: defaults to git@localhost:gitolite-admin.git
- admin_system_user: defaults to "trac"; this is the name in gitolite of the system user running the trac web process
- default_private: defaults to True; when set to True (the default) repositories known to Trac which are missing from gitolite.conf will not be visible through the Trac source browser to any users. Set this to False to defer those repositories' permissions to the rest of the Trac permission system.
- all_includes_anonymous: defaults to False; when set to True, repositories with @all = R in gitolite.conf will be viewable through the web by anonymous users. The default is to make these repositories viewable by all logged-in users only.
