Testsuite failures on SuperH architecture

[glaubitz]

Hello!

Pillow currently fails to build from source on the buildds for the sh4 (Renesas SuperH) port of Debian. The testsuite crashes at some point with a traceback starting in the file /usr/lib/python2.7/dist-packages/nose/plugins/multiprocess.py.

I am not really an expert in Python but I would assume this issue arises since Pillow makes wrong assumptions about the underlying architecture. But please have a look at it yourself, I am attaching a the full build log [1]. I am also happy to provide further details if necessary and I would be happy to test any patches.

Cheers,
Adrian

Thanks. How about 2.7.0? Looks like the multiprocessing test failed. Maybe you can disable that one.

Alright, that was actually my guess :). I will ask the maintainer in Debian to disable that particular test on sh4. I am a Debian Developer myself but I don't maintain Pillow.

Could you give me a quick hint how to disable it so I can come up with a patch right away? Otherwise I am sure that Matthias Klose (maintainer of Pillow in Debian) will be able to do that as well.

Thanks!
Adrian

If these are nose tests, then pass 0 to --processes to disable multiprocessing:

  --processes=NUM       Spread test run among this many processes. Set a
                        number equal to the number of processors or cores in
                        your machine for best results. Pass a negative number
                        to have the number of processes automatically set to
                        the number of cores. Passing 0 means to disable
                        parallel testing. Default is 0 unless NOSE_PROCESSES
                        is set. [NOSE_PROCESSES]
