Trac is an open source, Web-based project management and bug tracking system. The program is inspired by CVSTrac, and was originally named svntrac due to its ability to interface with Subversion.^[3] It is developed and maintained by Edgewall Software.

Trac is written in the Python programming language. Until mid-2005, it was available under the GNU General Public License; since version 0.9, it has been released under a modified BSD license.^[4]

Features

Trac allows hyperlinking information between a bug database, revision control and wiki content. It also serves as a Web interface to the following revision control systems: Subversion, Git, Mercurial, Bazaar, Perforce and Darcs. Prior to version 0.11, the web front end presentation of Trac was handled by the ClearSilver template system. Starting with 0.11, an in-house template system called Genshi is used, although compatibility with ClearSilver-based plugins will remain for several versions.^[5]

Other features include:

• Project management (Roadmap, Milestones, etc.)

• Ticket system (bug tracking, tasks, etc.)
• Search engine for tickets
• Email notifications
• Fine-grained permissions (since 0.11)

Trac is reported to have more than 450 major installations worldwide.^[14] Among the users of Trac are Tor^[15] and I2P^[16] projects, NASA's Jet Propulsion Laboratory, which reports that it uses this tool to manage various deep space and near space projects; Twisted, an asynchronous networking framework implemented in Python; the Dojo Toolkit, one of the popular Open source JavaScript library projects; Nginx, an open source Web server and a reverse proxy server; Piwik, a free software equivalent to services like Google Analytics; and WordPress, the popular blogging platform. They all use Trac for bug tracking and as a source tree viewer. Some projects also use Trac's wiki. The Apache Bloodhound project is a fork of Trac.
