Bonsai is a web-based tool for managing CVS, the Concurrent Versioning System . Using Bonsai, administrators can control open/closed status of trees, query a fast relational database back-end for change, branch, and comment information, and view changes made since the last time the tree was closed. Bonsai also integrates with Tinderbox, the Mozilla automated build management system.
CVS integration is best accomplished, at this point, using the Bugzilla Email Gateway.
Follow the instructions in this Guide for enabling Bugzilla e-mail integration. Ensure that your check-in script sends an email to your Bugzilla e-mail gateway with the subject of "[Bug XXXX]", and you can have CVS check-in comments append to your Bugzilla bug. If you want to have the bug be closed automatically, you'll have to modify the contrib/bugzilla_email_append.pl script.
There is also a CVSZilla project, based upon somewhat dated Bugzilla code, to integrate CVS and Bugzilla through CVS' ability to email. Check it out at: http://homepages.kcbbs.gen.nz/~tonyg/.
Another system capable of CVS integration with Bugzilla is Scmbug. This system provides generic integration of Source code Configuration Management with Bugtracking. Check it out at: http://freshmeat.net/projects/scmbug/.
You can find the project page for Bugzilla and Teamtrack Perforce integration (p4dti) at: http://www.ravenbrook.com/project/p4dti/ . "p4dti" is now an officially supported product from Perforce, and you can find the "Perforce Public Depot" p4dti page at http://public.perforce.com/public/perforce/p4dti/index.html .
Integration of Perforce with Bugzilla, once patches are applied, is seamless. Perforce replication information will appear below the comments of each bug. Be certain you have a matching set of patches for the Bugzilla version you are installing. p4dti is designed to support multiple defect trackers, and maintains its own documentation for it. Please consult the pages linked above for further information.
Subversion is a free/open-source version control system, designed to overcome various limitations of CVS. Integration of Subversion with Bugzilla is possible using Scmbug, a system providing generic integration of Source Code Configuration Management with Bugtracking. Scmbug is available at http://freshmeat.net/projects/scmbug/.
