SVN/Trac Integration
A long time ago I wrote an article titled CVS/Bugzilla Integration. Here is an updated version for subversion and trac.
Note that it doesn’t require access the trac python libs or database; it just uses HTTP. But it does require BeautifulSoup. Install it by adding it to your hooks post-commit script. (it takes the normal params of REPOS and REV).
