Trac

Trac is an enhanced wiki and issue tracking system for software development projects. It provides interfaces to Subversion and Git, an integrated Wiki and convenient reporting facilities.

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. 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.

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.

Adoption

Trac is reported to have more than 450 major installations worldwide. 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; 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, all use Trac for bug tracking and as a source tree viewer. Some projects also use Trac's wiki.

Trac allows wiki markup in issue descriptions and commit messages, creating links and seamless references between bugs, tasks, changesets, files and wiki pages. A timeline shows all current and past project events in order, making the acquisition of an overview of the project and tracking progress very easy. The roadmap shows the road ahead, listing the upcoming milestones.
