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.
Per https://docs.python.org/dev/whatsnew/3.14.html#multiprocessing: The default start method (see Contexts and start methods) changed from fork to forkserver on platforms other than macOS & Windows where it was already spawn. 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().

This bug appears to have been reported against 'rawhide' during the Fedora Linux 42 development cycle. Changing version to 42.
