This post is about configuring Trac and Git to work together properly. As you might be knowing, Git is a DVCS – Distributed Version Control System and Trac is a project management system. By default, Trac supports SVN, but there are plugins for Git and Mercurial. I don’t know if there are plugins for other repositories like Bazaar, etc.
In the default configuration in Trac’s Git plugin, the repository is not cached and setting
repository_sync_per_request to blank doesn’t stop Trac from syncing repostiories on each request. This is a big performance disadvantage and can big a real big trouble if you have lots of repositories with quite a lot of commits.
