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.
I couldn’t reproduce *this* error, but I reproduced a different error: =================================== FAILURES =================================== ____________________________ test_process_teardown _____________________________ request = <FixtureRequest for <Function test_process_teardown>> def test_process_teardown(request): proc = ProcessForTeardownTest() proc.start() request.addfinalizer(proc.terminate) proc.join(10) # starting new Python process may cost a lot assert proc.exitcode is not None, "process teardown hangs" > assert proc.exitcode == 0, f"Python process died with code {proc.exitcode}" E AssertionError: Python process died with code 1 E assert 1 == 0 E + where 1 = <ProcessForTeardownTest name='ProcessForTeardownTest-1' pid=1367 parent=1306 stopped exitcode=1>.exitcode tests/test_asyncio.py:388: AssertionError ----------------------------- Captured stderr call ----------------------------- Traceback (most recent call last): File "/usr/lib64/python3.14/multiprocessing/forkserver.py", line 335, in main code = _serve_one(child_r, fds, unused_fds, old_handlers) File "/usr/lib64/python3.14/multiprocessing/forkserver.py", line 375, in _serve_one code = spawn._main(child_r, parent_sentinel) File "/usr/lib64/python3.14/multiprocessing/spawn.py", line 132, in _main self = reduction.pickle.load(from_parent) ModuleNotFoundError: No module named 'tests' I fixed that in https://src.fedoraproject.org/rpms/python-zmq/pull-request/20, and that PR built successfully in COPR as https://copr.fedorainfracloud.org/coprs/g/python/python3.14/build/8652276/, so I’m going to call it a fix even though it doesn’t match the original report. Please do reopen this if you start seeing "zmq.error.ZMQError: Socket operation on non-socket" again. While I built this several times in mock using packages from the Python 3.14 COPR, there could still be some kind of flaky testing issue.
FEDORA-2025-2e53d31ab3 (python-zmq-26.2.1-3.fc43) has been submitted as an update to Fedora 43. https://bodhi.fedoraproject.org/updates/FEDORA-2025-2e53d31ab3
FEDORA-2025-2e53d31ab3 (python-zmq-26.2.1-3.fc43) has been pushed to the Fedora 43 stable repository. If problem still persists, please make note of it in this bug report.
Thank you. Things change in Copr so dynamically it's often tricky to determine what's one-off and what's persistent.
