[Buildbot-devel] client-side subversion ChangeSource?

[John Pye]

Did you try using the 'cvs log' command, I wonder? Maybe that would
allow your buildbot to find out what (if anything) has changed with a
bit less bandwidth being used.

Following on from my post, I have fixed a couple of bugs in my little
Subversion monitor script and so I'll attach it again here. This script
detects, using 'svn log', who the user was that made the change, what
the revision number is, and what files were changed, without needing to
transfer any of the files. It's written in python so should, with the
exception of the Python 'commands' module, be fairly easily ported to
other OSs.

Cheers
