Originally reported in issue #779 by @astrofrog.

I've tested this branch on MacOS 10.7 with freetype 2.4.9 (14.1.8), and all tests pass except three (the font_styles ones):

It looks as though somehow the font styles don't work on my system when anti-aliasing is disabled?

Does deleting your font cache (~/.matplotlib/fontList.cache) help?

Can you post your ~/.matplotlib/fontList.cache file? I suspect it isn't indexing the fonts correctly.

I tried removing it but the errors were still there.

Can you run this gist: https://gist.github.com/2159040

Run with debugging messages on and post the console output (also check test.png to see if it looks styled).

python font_styles.py --verbose-debug-annoying

Here is the log: http://pastebin.com/KbSyQ3ym

The text is not styled.

Just to confirm, since I see it in the logs: Have you been removing (and sending me) /Users/Shared/Jenkins/Home/.matplotlib/fontList.cache (since this is running in the Jenkins context) and not ~/.matplotlib/fontList.cache?

Still stumped as to what's going on. The fontList.cache you sent me works perfectly here (after updating the paths).

I did send the Jenkins one - but I think the one I had sent before was generated by Jenkins, so I removed it and then ran your script, which re-generated the file, and now the styles look fine. So somehow, in the restricted Jenkins environment, the font cache file that is generated has issues... I'm now going to run the Jenkins tests again with the fontList.cache file that was generated when I ran your script to see what happens. Anyway, it seems that this is an issue related to running in Jenkins rather than a real matplotlib bug. I'll report back.

Ok, this was indeed some strange artifact of running the tests on Jenkins. If I run the tests sequentially for different Python/Numpy versions, and remove fontList.cache between each run, then things work fine. The issue must be to do with the cache pointing to the fonts in the wrong matplotlib path (i.e. if the 2.7 & 1.6.1 tests run first, then the cache will contain fonts in the 2.7 & 1.6.1 path, which might confuse the other Python versions). Anyway, I don't think this is really a matplotlib bug, so this issue can be closed.
