Hey, if you're going to be using p4poller as an example, use the
attached one instead. It makes some improvements:
- it understands branches. The next path component after your base is
taken to be the path name. (I haven't looked at how the Subversion
push one works; maybe its way is similar.) It makes a dictionary as
it goes in case a single Perforce change contains changes to multiple
branches and thus needs to be mapped to multiple buildbot Change
- it reports error return from p4. (Try it when P4PORT points to a
socket in which nothing is listening.)
- it gets the results back from the first poll. This is the SIGCHLD
problem I mailed the list about a couple days ago.
- it won't launch a new "p4 changes" if the last one hasn't finished.
(In other words, if the server is struggling, it doesn't make matters
This is part of a patch in progress.
