I'm currently trying out
Mercurial, a distributed SCM that's 99% pure Python. I was able to migrate some of my recent projects (including full history) over to it. My repository is
http://hg.saddi.com/.
I haven't fully committed yet, but it's very tempting since it's far easier to install (it's literally a "python setup.py install"). Setting up the web interface was a breeze too (it's built on top of WSGI!)
Oh well, I mention this now because I've finally committed something to my Hg repository. In other words, my SVN and Hg repositories are now out of sync...
Anyway, I know there's a Trac plugin for Hg which I will have to try out as well. Not sure if and when I'll fully commit. Only time will tell and I really haven't been working on any personal projects lately...
