Description of problem:
Package python-pytest-cov fails to build from source in Fedora Rawhide.

Due to reasons described in https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/thread/XO5QGOXBWHFG7AOGDQBG23AQDS2MDTWI/ a rebuild of python-pytest-cov is needed in Fedora Rawhide (44) and Fedora 43.

Version-Release number of selected component (if applicable):
5.0.0-5.fc43

Steps to Reproduce:
fedpkg build

Hello. This is a bulk comment.

This package still needs to be rebuilt and/or shipped with Python 3.14.0rc2+ bytecode in Fedora 43.

The Beta Freeze of Fedora 43 is scheduled to start today. Please prioritize this bugzilla accordingly.

Thanks.

I maintain python-mwparserfromhell which depends on pytest-cov. Not sure I should take over maintainership but I'm happy to help and test. (I'm still unsure how coordination with depending packages works for a package like this.)

Notably, the upstream goes through major versions rather fast: https://github.com/pytest-dev/pytest-cov/tags (we are currently at 5.0.0  from early 2024, there is an open PR for 6.2.1 released June this year and 7.0.0 just came out in early September).

I'm happy to become co-maintainer (I'll make sure that it doesn't end up neglected again and help whenever necessary), maybe even mentee on how updates in such a package can be done.

Cheers!

David

> I maintain python-mwparserfromhell which depends on pytest-cov.

It doesn’t need to depend on it, and per https://docs.fedoraproject.org/en-US/packaging-guidelines/Python/#_linters, it shouldn’t. Try this: https://src.fedoraproject.org/rpms/python-mwparserfromhell/pull-request/1

Comment 6 Ben Beasley 2025-10-28 12:23:35 UTC
There are 138 packages that currently depend on this. For that reason, I suspect that somebody will end up “rescuing” this package. However, patching out the dependency is the right answer for almost any individual impacted package.

Comment 7 David Auer 2025-10-28 20:14:00 UTC
Ben, thanks a lot for the suggestion and PR! Consider me no longer interested in this package then ;)
