[matplotlib-devel] 'NoneType' object has no attribute 'endswith' when running tests in a chroot

[Sandro T. <mo...@de...>]

Hello,
I've been trying to fix this problem for hours, and it's getting me
mad but to no conclusion, so I'm asking here.

In Debian we build our packges in a chroot, with all the minimum
dependecies needed to build the package (to guarantee reproducibility
and avoid weird effect of local installed packages), and so also the
unittests are runt here. While enabling the matplotlib unittest in
that chroot, I'm getting this error:

======================================================================
ERROR: matplotlib.tests.test_axes.test_arc_ellipse.test
----------------------------------------------------------------------
Traceback (most recent call last):

  File "/usr/lib/python2.6/posixpath.py", line 67, in join

(repeated for several times, it seems like a patter, given the output
of the test execution is:

..K.............EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK.EK..EK.EK.EK.EK.EK.EK.EKK...EK...EK.EK..EKEK..EK.EK.EK.EK.EK..EK.EK.EK[....]

and so on) so it seems the code can't find the datapath location. In
order to fix that, I'm calling the test suite like this:

PYTHONPATH=build/lib.linux-x86_64-2.6 \
        MATPLOTLIBDATA=/tmp/buildd/matplotlib-1.1.1~rc1/lib/matplotlib/mpl-data/
\
        MPLCONFIGDIR=. \
                python2.6 -c "import matplotlib as m ; m.test(verbosity=1)"

and in . there's a matplotlibrc file with simply:

  datapath : /tmp/buildd/matplotlib-1.1.1~rc1/lib/matplotlib/mpl-data/

in it; but still I got all of these failures. Anyone knows where I can
look to fix that?

Thanks in advance,

I'm not sure about this one.  Could it be due to not having a font cache 
in ~/.matplotlib?

This is most likely due to some of the testing dependencies not being 
present.  matplotlib uses ghostscript for rendering PDF and inkscape for 
rendering SVG (but only when testing).  See this documentation:

http://matplotlib.sourceforge.net/devel/coding_guide.html#testing

(Note the the PIL requirement goes away with matplotlib git master -- 
it's only required for the 1.1.x series).

(sigh - only now I find the time to work on it)

yep indeed - inkscape was missing, once installed almost all the tests
are passing, but I got some of them fail since the images doesn't
match: how can I report those problem? an issue on github attaching
the images pairs and the tests running output?
