Cruisecontrolrb Cruise Control.rb

For various reasons, the people who host our Subversion repository would prefer that we don't poll the repository. So I wrote the attached patch to support a post-commit hook. The changes add a new notification controller, which supports a single dirs_changed action. This works together with a simple post-commit hook which sends a list of changed directories. Here's an example post-commit hook: ------------------------ #!/bin/sh WGET=/opt/local/bin/wget SVNLOOK=/opt/local/bin/svnlook CC_URL=http://cruise.82ask.com/notification/dirs_changed $WGET -q -O- --post-data="`$SVNLOOK dirs-changed $1`" $CC_URL > /dev/null ------------------------ I think that I've made these changes in a "sympathetic" way to the existing code, but have had to restructure the PollingScheduler code somewhat. At some point, I should probably modify PollingController so that it can be configured so that it doesn't poll at all (we currently run with the polling interval set to 12.hours). Please let me know what you think of these changes - if there are things that should be changed in order to make this fit in with the "CruiseControl way", I'd love to hear about them.
