We would like to trigger builds for each and every commit made into Subversion. A post-commit hook, i suspect, would communicate to the build server and pass in the SVN revision id. This seems trivial to do. In fact, every CI server that I've evaluated thus far provides this capability. ...except, seemingly, TeamCity. Is it true that TeamCity only supports polling? This is an important need (perhaps a show stopper), and would be a real shame since TeamCity seems like a strong contender otherwise.
I did find an addon named vcsupdate. However, I'm not sure that is what I need. That seems to trigger TeamCity to then poll. So, it may not be per revision. There doesn't seem to be a way to pass the revision id to it.
Can someone confirm or deny whether VCS-triggered builds are supported. If not, why not! ..and when is it coming.
