testsuite fails on Alpine s390x #62

By Tuan Hoang on 2019-05-18T20:33:33.712Z

Hello,

I'm seeing a couple of test failures on Alpine s390x. Would you mind having a look ?
The build log could be found at : https://build.alpinelinux.org/buildlogs/build-3-10-s390x/community/py-img2pdf/py-img2pdf-0.3.3-r1.log
Or back up at : http://tpaste.us/YM6r

Thanks,

And this is how Alpine buildscript looks like : https://git.alpinelinux.org/aports/tree/community/py-img2pdf/APKBUILD

img2pdf builds fine on Alpine on other little endian architectures like x86 and ppc64le.

The log looks more like a PIL/Pillow problem. Are you running PIL/Pillow test suites on Alpine under s390x?

I just ran the testsuite on s390x on Debian unstable where this worked fine so this seems to be Alpine specific and not a problem with s390x in general.

Could you maybe just try creating an empty image with your PIL implementatation on Alpine on s390x and run the tobytes() member function of the image? That is the one that seems to fail.

Looks like Alpine s390x does not run py-pillow testsuites : https://git.alpinelinux.org/aports/tree/main/py-pillow/APKBUILD#n17 (meaning make check is not run).

I disabled it a while ago: https://git.alpinelinux.org/aports/commit/main/py-pillow/APKBUILD?id=b65c2c0c9a5606eabd0361fa4e03c981bd0f17be.

It's a known from upstream pillow.

Would you mind explaining 'image' ?

This small snippet should throw an error on s390x alpine:

python3 -c 'from PIL import Image; img=Image.new("RGB", (10,10));img.tobytes()'

By Tuan Hoang on 2019-05-18T22:12:46.269Z

Yes.

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3.7/site-packages/PIL/Image.py", line 756, in tobytes
    l, s, d = e.encode(bufsize)
MemoryError

In fact Fedora's pillow also skips test on s390x. Looking at Debian build and patches, I couldn't see how it does not face the test failures.

In that case, this is not an img2pdf problem.

If PIL doesn't work on Alpine on s390x, then img2pdf (which depends on PIL) cannot work on it either. And to fix it, you have to change PIL in Alpine and not img2pdf. Once your PIL is fixed, img2pdf will likely work as well.

Thanks for the explanation. I'm closing this issue.
