Andrew and I just spent a couple of hours on the phone trying to reconcile our freetype rendering discrepancies, and after much tedious poor-man's debugging, we finally figured out what was wrong. We thought we were using the same version of freetype but were not. The fault was mine: I configured my buildbot to recognize the right version of freetype at buildtime but not runtime. We've fixed this, we now both run the same version of freetype, and we are getting identical mpl images. We are very excited by the sea of green at
http://mpl-buildbot.code.astraw.com/waterfall Now that we have two bots passing the regression tests, we have big plans: * enable buildbots for more platforms (solaris and win32, we already have osx and linux) * enable buildbots for all supported versions of python (2.4, 2.5 and 2.6) * make the unit testing infrastructure in the "test" dir easier to use and extend, so it becomes trivial to drop in a new test (and then drop in a lot of tests) * enable tarballs and platform specific binary installers from the buildbots which upload to a nightly directory that users can grab stuff from * send out emails on any buildbot failures to the matplotlib-buildbot mailing list In preparation for the last point, I have created https://lists.sourceforge.net/lists/listinfo/matplotlib-buildbot so subscribe if you are interested in getting notices of failures. Andrew is taking a break before he configures the bot to email on failures, but he'll probably have it activated soon. We'll probably force a failure by uploading a bad image as a baseline to debug the email script, so there may be some false negatives coming out on the list over the next day or two, but once we have everything working the list should accurately reflect unit test failures. Thanks to Andrew for pushing this through. It's a big step forward to go from the poor-man's unit testing that we have in backend_driver to a real framework doing image diffs across platforms triggered by svn commits.
