python-pytest-twisted fails to build with Python 3.14.0b1. Creating the ticket for tracking purposes. twisted doesn't fully work with Python 3.14 yet. It was reported upstream. Failing twisted tests were skipped for now. But this causes python-pytest-twisted to fail, the fail comes from the codepath that is not prepared for Python 3.14. ======================== 52 passed, 8 skipped in 14.71s ======================== INTERNALERROR> Traceback (most recent call last): INTERNALERROR> File "/usr/lib/python3.14/site-packages/_pytest/main.py", line 279, in wrap_session INTERNALERROR> config._do_configure() INTERNALERROR> ~~~~~~~~~~~~~~~~~~~~^^ INTERNALERROR> File "/usr/lib/python3.14/site-packages/_pytest/config/__init__.py", line 1118, in _do_configure INTERNALERROR> self.hook.pytest_configure.call_historic(kwargs=dict(config=self)) INTERNALERROR> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^ INTERNALERROR> File "/usr/lib/python3.14/site-packages/pluggy/_hooks.py", line 535, in call_historic INTERNALERROR> res = self._hookexec(self.name, self._hookimpls.copy(), kwargs, False) INTERNALERROR> File "/usr/lib/python3.14/site-packages/pluggy/_manager.py", line 120, in _hookexec INTERNALERROR> return self._inner_hookexec(hook_name, methods, kwargs, firstresult) INTERNALERROR> ~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ INTERNALERROR> File "/usr/lib/python3.14/site-packages/pluggy/_callers.py", line 139, in _multicall INTERNALERROR> raise exception.with_traceback(exception.__traceback__) INTERNALERROR> File "/usr/lib/python3.14/site-packages/pluggy/_callers.py", line 103, in _multicall INTERNALERROR> res = hook_impl.function(*args) INTERNALERROR> File "/builddir/build/BUILD/python-pytest-twisted-1.14.3-build/BUILDROOT/usr/lib/python3.14/site-packages/pytest_twisted/__init__.py", line 472, in pytest_configure INTERNALERROR> reactor_installers[config.getoption("reactor")]() INTERNALERROR> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^ INTERNALERROR> File "/builddir/build/BUILD/python-pytest-twisted-1.14.3-build/BUILDROOT/usr/lib/python3.14/site-packages/pytest_twisted/__init__.py", line 418, in init_asyncio_reactor INTERNALERROR> _install_reactor( INTERNALERROR> ~~~~~~~~~~~~~~~~^ INTERNALERROR> reactor_installer=asyncioreactor.install, INTERNALERROR> ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ INTERNALERROR> reactor_type=asyncioreactor.AsyncioSelectorReactor, INTERNALERROR> ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ INTERNALERROR> ) INTERNALERROR> ^ INTERNALERROR> File "/builddir/build/BUILD/python-pytest-twisted-1.14.3-build/BUILDROOT/usr/lib/python3.14/site-packages/pytest_twisted/__init__.py", line 434, in _install_reactor INTERNALERROR> reactor_installer() INTERNALERROR> ~~~~~~~~~~~~~~~~~^^ INTERNALERROR> File "/usr/lib/python3.14/site-packages/twisted/internet/asyncioreactor.py", line 304, in install INTERNALERROR> reactor = AsyncioSelectorReactor(eventloop) INTERNALERROR> File "/usr/lib/python3.14/site-packages/twisted/internet/asyncioreactor.py", line 50, in __init__ INTERNALERROR> _eventloop: AbstractEventLoop = get_event_loop() INTERNALERROR> ~~~~~~~~~~~~~~^^ INTERNALERROR> File "/usr/lib64/python3.14/asyncio/events.py", line 718, in get_event_loop INTERNALERROR> raise RuntimeError('There is no current event loop in thread %r.'

According to https://docs.python.org/dev/whatsnew/3.14.html#id3 Removed implicit creation of event loop by asyncio.get_event_loop(). It now raises a RuntimeError if there is no current event loop.

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-b1/ 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.
