[Buildbot-devel] source change for sf.net hosted CVS

[Mark Pauley]

Sorry guys, been busy... you know how it is ;)

I'm still working on the CVSPolledSource merge.
I'm just hacking through the tests now.  Thanks to the p4poller  
tests, think I have a pretty good idea of how to test this sucker.

One issue I'd like to mention is that CVS is file-centric, that is  
CVS has a different version number for every file.
Currently, my hack is to just check a repository out to a given  
sandbox location on the master, and perform cvs update on that  
directory, and then examine the logs to get the details.
I shouldn't need to do this for the tests, all of the data is static,  
but still the solution smells weak and requires something that none  
of the other source change modules require.

This is not now p4 operates apparently, and I think my method is a  
big fat hacky hack.  It works, but it's ugly.  Can anyone else think  
of a better way to do this?
