[Buildbot-devel] Cleaning, but not every build

[Mark Roddy]

If I'm understanding correctly, I've had to solve these issues myself.
 Let me know if this is incorrect:

1) 'Incremental' and 'Full' builds - The only way I've found to
accomplish this is to have two different builds setup (which you noted
you could do).  There may be some work around I did not think of, but
also keep in mind you'll probably want to do a 'full checkout' on your
full builds rather then an update for which you'd need two different
build steps.  I've run into issues where someone would delete a file,
and subversion would delete the file on an update and the generated
binary file would remain resulting in tests that should have failed
but did not.

2) Building Changes One By One - Are you referring to that fact that a
build triggered by a source code commit could actually have several
commits in place?  If so you can always drop the wait time to
something pretty low so that each commit gets its own build, but then
you might have two problems.  Broken builds that someone fixed in a
commit shortly there after, and people who have multiple commits to a
single piece of work that actually leave things broken between them.
I'd suggest that use rebuild from the web page and specify the
revision number to be rebuilt until you find the problem.
