Trac is anopen-source, web-basedproject management andbug tracking system. It has been adopted by a variety of organizations for use as a bug tracking system for both free and open-source software and proprietary projects and products.[4] Trac integrates with majorversion control systems including ("out of the box")Subversion andGit. Trac is used, among others, byDjango,[5]FFmpeg,[6]WebKit,[7]0 A.D.,[8] andWordPress.[9]
Trac is available on all majoroperating systems includingWindows via Installer orBitnami,[10]OS X viaMacPorts orpkgsrc,Debian,[11]Ubuntu,[12]Arch Linux[13] orFreeBSD,[14] as well as on variouscloud hosting services.
Inspired by CVSTrac, Jonas Borgström and Daniel Lundin from Edgewall Software started writingsvntrac in August 2003 usingSQLite andSubversion.[15] In December 2003 they renamed it toTrac. In February 2004 the Trac version was changed first from 0.0.1 to 0.1 and then directly from 0.1 to 0.5. That release was followed in March 2004 by 0.6 and 0.7, and 0.8 in November 2004.
Edgewall Software is an umbrella organization for hosting edgewall.org for the community to collaborate on developing open source Python software.[16] It used to offer software development, consulting and support services. Some of the earliest community members to collaborate in the open source development of Trac were Rocky Burt in March 2004, Christopher Lenz and Francois Harvey in May 2004, Christian Boos and Otavio Salvador in December 2004 and Mark Rowe March 2005.[17]
In August 2005 the license was changed fromGPL-2.0-or-later toBSD-3-Clause. The first release under this final license was Trac 0.9 in October 2005, which among other features introducedPostgreSQL database support.
Trac 0.10, released in September 2006, was an important release that first introduced the component system that to this day allows plugins to extend and add features to Trac's core. Trac itself since this point consists mainly of optional plugin components that can be disabled or replaced entirely.MySQL database support is added as one such core component. This release added support forversion control systems other than Subversion by external plugins.Mercurial support was provided through a separate plugin due to its GPL license restrictions.[18] Trac 0.11, released in June 2008, changed the HTMLtemplate system from ClearSilver[19] toGenshi, breaking compatibility with many of the older plugins.
Trac 0.12 was released in June 2010 and became a stable long term release with the latest point release 0.12.7 from July 2015. It addedinternationalization and localization support usingBabel, and allows using multiple version control repositories at once.
Trac 1.0 was released in September 2012,[20] the previous stable long term supported version with the latest point release 1.0.13 from September 2016. It included the previously external plugin forGit version control support.
Trac 1.1.1 from February 2013 through 1.1.6 from July 2015 are releases without long-term support and compatibility guarantees, that turned into Trac 1.2 from November 2016.[21]
Trac 1.4 from August 2019 was the last stable release running on Python 2.7. It uses theJinja template system.
Trac 1.6 from September 2023 is the current stable release and works exclusively on Python3. Many of the plugins have also been rewritten to work on Python3 as well as Jinja.
Trac offers a no-frills approach toproject management by deeply integratingticket tracking,version control (for which multiple repositories per environment are supported), andwiki. It allowshyperlinking information between these systems, include wiki content directly in a ticket or list tickets automatically on wiki pages.[22][23][24][25][26][27]
The ticket system can be used for tracking bugs, tasks, issues, incidents or any other kind of ticket. Customized reports can be generated from parametric storedSQL queries or using an interactive ticket query system. There is also an integrated search engine and a fine-grained permission system.
Additional project management features include grouping tickets into milestones and a roadmap where the milestones and their progress are listed and visualized. The recent activity is shown on a timeline page, and users are notified by email or can subscribe toRSS oriCalendar feeds.
Trac has a plugin system to add additional features and to integrate with external tools.[28] Besides the coreSVN and Git support, Trac can connect via plugins to many otherversion control systems, includingBazaar,CVS,Darcs,Mercurial,Monotone, andPerforce.[citation needed]Features provided by plugins includeContinuous integration, account management,tags, spam filtering, blogs and discussion fora, and connectors forXML-RPC andPastebin.[non-primary source needed]
