[Buildbot-devel] Stopping a Build Upon Output

[Roy S. Rapoport]

My builds have update,build, and test phases (in that order).  The tests
take a while -- in one case, 4206 seconds.  

Now, a build may actually conclude with no changes (because nothing has
had to be rebuilt).  I would love to find a way to:
A) Based on output from a build step, determine this has happened; and
B) When it happens, skip doing the tests.  This isn't a 'haltOnFailure'
situation -- if it happens, we're all good and we want to say we're
successful.

Suggestions?
