If you require the threading incompatible fork start method you must explicitly request it using a context from multiprocessing.get_context() (preferred) or change the default via multiprocessing.set_start_method().

Smith in gh-84559.) https://docs.python.org/3.14/whatsnew/3.14.html For the build logs, see: https://copr-be.cloud.fedoraproject.org/results/@python/python3.14/fedora-rawhide-x86_64/08651086-python-redis/ For all our attempts to build python-redis with Python 3.14, see: https://copr.fedorainfracloud.org/coprs/g/python/python3.14/package/python-redis/ Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.14: https://copr.fedorainfracloud.org/coprs/g/python/python3.14/ Let us know here if you have any questions. Python 3.14 is planned to be included in Fedora 43. To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.14. A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon. We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.

This is not related to Python 3.14 per se: https://koschei.fedoraproject.org/package/python-redis
This seems to perhaps be fixed by https://github.com/redis/redis-py/pull/3442 which is in the new release that just dropped a few days ago. They seem to have moved all the test setup around though, so will require a bit of work...

We have that patch rebased for the currently packaged version, but the 6 new test failures as visible since valley 8.1 in https://koschei.fedoraproject.org/package/python-redis block us. I'll open a PR to skip them, but this should probably be brought upstream.
