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.^[1] 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.^[2]

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.^[3]

Other features include:

• Project management (Roadmap, Milestones, etc.)
• Ticket system (bug tracking, tasks, etc.)
• Fine-grained permissions (since 0.11)
• Timeline of all recent activity
• Wiki (syntax similar to MoinMoin)
• Customized reporting
• VCS web interface
• RSS Feeds
• Multiple project support (planned for post-1.0 versions)
• Environment extensibility (via Python plugins)
• iCalendar export^[4]
• Multiple Repository Support per environment (since 0.12)
• Interface localizations (since 0.12)

Adoption

Trac is reported to have more than 450 major installations worldwide.^[5] Among the users of Trac is 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; Piwik, a free software equivalent to services like Google Analytics; and WordPress, the popular blogging platform, all use Trac for bug tracking and as a source tree viewer. Some projects also use Trac's wiki.
