This would be a good script to add to pygame for the google testing project by Nicholas...
test_between_revisions.py r990 r1175 run_tests.py Then it could to a bisect build, and test between the revisions. It could take a file name to run between revisions. So you could pass it a file to run tests for you. eg. for this bug it could be: test_between_revisions.py r990 r1175 tests/manual/music.py It would download, and build them all, then run the tests. cu, On Thu, Apr 24, 2008 at 11:13 AM, Brian Fisher <[EMAIL PROTECTED]> wrote: > sweet, you rock. with 185 revisions between, then it only takes 8 more > get-build-test cycles to narrow it down to a single change :) > > > > On Wed, Apr 23, 2008 at 4:22 PM, Lenard Lindstrom <[EMAIL PROTECTED]> wrote: > > > I have been going through SVN.
