tests fail on less common architectures #2328

drew-parsons · 2021-03-17T10:30:43Z

xtensor tests fail on less common machine architectures, including i386, mipsel, s390x, and others. Build logs can be found at https://buildd.debian.org/status/package.php?p=xtensor&suite=experimental

There seem to be two separate sets of failures. test_xnpy fails on s390x, hppa, powerpc, ppc64, sparc64.

On i386 the failing tests are test_xbuilder, test_xfunction, test_xreducer, test_xnan_functions.

The xnpy error message on s390x is

Do you have the same error on all architectures for test_xnpy? From the message you've posted, it is definitely a big endian / little endian issue (we need to fix the expected value in the test since we always assume little endian).
Regarding the other failures, they look like precision / rounding issues.

Is it easy for you to test any branch from Github? If so, I can push some changes that will help to diagnose the problem.

drew-parsons · 2021-03-23T15:27:47Z

Not all arches. The test_xnpy failure is on s390x, hppa, powerpc, ppc64, sparc64. It passes on ARM in both armel (little endian) and armhf (arm64 also passes).

I can pull branches if needed to test (I can test on Debian experimental so the main distribution is not affected).

drew-parsons · 2021-03-23T20:53:08Z

That is, test_xnpy passed on amd64, arm64, armel, armhf, i386, mips64el, ppc64el, alpha, ia64, m68k, riscv64, sh4, x32.

drew-parsons · 2021-09-13T14:18:33Z

With xtensor 0.23.10, other tests now pass. Only the 3 tests in test_xnpy continue to fail. For s390x:

Partially fix xtensor-stack#2328

Not sure how to reimplement test_xbuilder.cpp. The failure appears when gcc is used (it seems to use FPU instead of SSE for floating point).

JohanMabille · 2024-01-04T20:37:52Z

Maybe we can use floating point comparisons / assertions instead

Maybe we can use floating point comparisons / assertions instead

I think it is enough to make the step be power of 2, like 0.25f
