PGF-related test failures on Mac OS-X #2097

mdboom · 2013-05-31T00:53:38Z

These were reported by @r-owen in the process of making osx binaries for 1.3.0rc2. @pwuertz: do you have any ideas? Something to do with the TeX environment?

pwuertz · 2013-05-31T08:01:42Z

It looks like XeTeX cannot find the Bitstream Vera Serif system font. The odd thing about this is that the backend shouldn't have selected a font that isn't in the list of system fonts. I'm retrieving that list from font_manager.findSystemFonts().

Is it possible that findSystemFonts includes the fonts provided by the matplotlib package? These are probably unknown to the OS and thus not available to XeTeX.

pwuertz · 2013-05-31T08:04:33Z

However, if Bitstream Vera Serif is indeed a regular system font there is something wrong with the TeX environment.

jenshnielsen · 2013-05-31T08:25:34Z

I have seen this issue too on OSX. Installing bitstream vera true type fonts makes the test pass. So yes the problem is that a non system available font is selected.

pwuertz · 2013-05-31T10:22:10Z

Ok, then it is a question of whether matplotlib fonts should show up in font_manager.findSystemFonts() or not.

pwuertz · 2013-06-02T10:51:17Z

@jenshnielsen Are you able to confirm that Bitstream Vera Serif is in the list retrieved from font_manager.findSystemFonts() on a system without this font installed?

jenshnielsen · 2013-06-02T17:07:20Z

The output of Vera fonts on my mac without any user installed fonts is (here the test failed)

a = font_manager.findSystemFonts()
matching = [s for s in a if "Vera" in s]
matching =

I guess these fonts may be installed by Xquarts ? Which I have installed but XeTeX does not use them.

With user installed fonts. Here the tests pass.

I have not tried to uninstall Xquarts

jenshnielsen · 2013-06-02T17:21:11Z

The X11 fonts are not install into the Mac OS Font viewer "Font Book". I can't remember how XeTeX findes the fonts but this might be the explanation?

pwuertz · 2013-06-02T18:52:22Z

This could indeed explain the issue. XeTeX uses OS-native methods for finding fonts. If OSX applications don't know about X11 fonts then XeTeX won't find them neither. I was thinking about using fontconfig to retrieve the list of system fonts. Do you know if the fc-list command is always available on OSX? Is it safe to assume that it's always present on Linux?

jenshnielsen · 2013-06-02T19:26:16Z

I have fc-list which does not fine the X11 fonts. That seems like a good solution. But it is installed by fontconfig from homebrew as a dependency of pango so I don't think we can rely on that being available all the time.

mdboom · 2013-06-04T13:10:03Z

findSystemFonts is a poorly named function. It's really intended to find more than just fonts that ship with matplotlib.

We do have win32InstalledFonts and OSXInstalledFonts however, so maybe we should add a function that wraps those that only returns "os findable" fonts and use that.

jenshnielsen · 2013-06-04T13:27:44Z

Yes that works as expected and does not return the X11 fonts.

a = font_manager.OSXInstalledFonts()
matching = [s for s in a if "Vera" in s]
['/Users/jenshnielsen/Library/Fonts/Vera.ttf',
 '/Users/jenshnielsen/Library/Fonts/VeraBd.ttf',
 '/Users/jenshnielsen/Library/Fonts/VeraBI.ttf',
 '/Users/jenshnielsen/Library/Fonts/VeraIt.ttf',
 '/Users/jenshnielsen/Library/Fonts/VeraMoBd.ttf',

 '/Users/jenshnielsen/Library/Fonts/VeraMono.ttf',

Ok, I'm going to prepare a patch that replaces findSystemFonts by win32InstalledFonts for win32 and a fc-list call for other systems. I think it's safe to assume that fontconfig is installed on unixoid systems, especially when a LaTeX distribution is present.

@pwuertz Does 9ccacff fix the issue? If so, I'm not sure it has been made into a pull request. Would you be able to do that so we can test it?

dmcdougall · 2013-07-01T17:13:05Z

I'm moving this out of blocker status, and into a v1.3 bugfix release milestone.

mdboom · 2013-09-17T19:01:33Z

Closed by #2117.

a59 · 2014-01-03T01:25:52Z

What is the status of fixing this?

aldanor · 2014-02-07T23:49:38Z

Same question; pgf still fails badly on OS X.

tacaswell · 2014-02-21T05:47:42Z

@pwuertz Can your re-base this commit (https://github.com/pwuertz/matplotlib/commit/9ccacffe81e0d4a48e4a4b19064460b94c6f77c9) on current master and push it back up? There is something very fishy going on with github here.

pwuertz · 2014-02-21T14:53:05Z

I put the PR back up (#2829). As mentioned before, I still have no clue if it is safe to assume that fc-list is always present on OSX systems with latex installed.

@nicola Is this an error from running the pgf tests? As far as I can see I removed any dependency on system fonts alltogether.
