Description Miro Hrončok 2021-06-14 10:56:02 UTC

It appears that kitty-0.21.1-1.fc35 fails to build in rawhide with some test failures on at least s390x:

ERROR: test_multiprocessing_spawn (
Traceback (most recent call last):
  File "/builddir/build/BUILD/kitty-0.21.1/kitty_tests/", line 48, in test_multiprocessing_spawn

    timeout = 1.999996468075551
Ran 102 tests in 3.145s

This blocks the Python 3.10 rebuild of the package.

Comment 1 Miro Hrončok 2021-06-14 10:58:20 UTC
This appears to be a timeout issue. Maybe the builder is just too slow? In copr, the package builds fine:

Running 3 scratchbuilds on all architectures to see how relevant the individual architectures are for the failures.

Comment 2 Artem 2021-06-14 11:11:02 UTC
Miro good day. I've in a hurry reported upstream
Didn't look into that yet, but seems like there is a two python version installed at the same time.

Comment 3 Miro Hrončok 2021-06-14 11:13:49 UTC
Observations: this happens on all architectures, even if I sed s/timeout=2/timeout=20/.

> seems like there is a two python version installed at the same time.

Indeed python3.9 is installed in root.log. Let me see why.

Comment 4 Miro Hrončok 2021-06-14 11:15:57 UTC
Because of:

    BuildRequires:  kitty

Let's build without tests first, only to build with tests later.

Comment 5 Miro Hrončok 2021-06-14 11:17:55 UTC
Oh no, wait, this is only because to add kitty on PATH. We should not install kitty to add it to PATH, we should add the recently built kitty to it.

Comment 7 Artem 2021-06-14 12:05:10 UTC
Miro thanks a lot for help. Now it built successfully on Rawhide.
