Bug#870128: libgpuarray: broken autopkgtests

[Steve Langasek]

Source: libgpuarray
Version: 0.6.9-2
Severity: important
User: ubuntu-devel at lists.ubuntu.com
Usertags: origin-ubuntu artful autopkgtest

Hi Ghislain,

Your latest upload of libgpuarray has replaced the previous python
autopkgtest with one based on pocl.  Unfortunately, this means that the
autopkgtests now consistently fail on ci.debian.net, because they can no
longer be run on a system without a gpu, e.g.:

======================================================================
ERROR: pygpu.tests.test_gpu_ndarray.test_asfortranarray((), 'float32', True, True, 1, 'f')
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/nose/case.py", line 197, in runTest
    self.test(*self.arg)
  File "/usr/lib/python2.7/dist-packages/pygpu/tests/support.py", line 44, in f
    func(*args, **kwargs)
  File "/usr/lib/python2.7/dist-packages/pygpu/tests/test_gpu_ndarray.py", line 196, in asfortranarray
    assert b.gpudata == gpu.gpudata
  File "pygpu/gpuarray.pyx", line 2260, in pygpu.gpuarray.GpuArray.gpudata.__get__ (pygpu/gpuarray.c:28840)
TypeError: This is for CUDA arrays.

I would suggest that it's more useful to have a basic autopkgtest that
passes on generic hardware than to have a deep autopkgtest which will never
succeed there.

I am filing this bug because failing autopkgtests are considered blockers
for inclusion of a package in the Ubuntu release.  Newer versions of
libgpuarray might not be included in Ubuntu releases until this is resolved.

Thanks,
