I briefly toyed with
Trac some time ago. Though I had to patch it to use WSGI, I found it pretty easy to use and maintain. My efforts eventually stalled, however, probably due to the way my public repository was derived from my real repository (i.e. lots of empty changesets).
Anyway, yesterday I updated to Trac 0.10.2 and was pleasantly surprised to find that it supported WSGI and flup's ajp and scgi servers out-of-the-box. The empty changeset issue is still there (which is my problem to fix). I just might have to split my repository up in the future.
Anyhow, flup has its own Trac site now:
http://trac.saddi.com/flup
The old flup site,
http://www.saddi.com/software/flup/ simply redirects there now. (And will probably do so for the foreseeable future.) Please continue to use this URL when referencing flup.
I locked down all the default pages, but all the flup-related pages (save for the front page) are editable by anyone. So feel free to contribute examples, FAQs, etc.
