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

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 (kitty_tests.tui.TestTUI)

Traceback (most recent call last):

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: https://copr.fedorainfracloud.org/coprs/g/python/python3.10/package/kitty/

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 https://github.com/kovidgoyal/kitty/issues/3712
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 https://github.com/kovidgoyal/kitty/issues/2881 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.
