python-klusta fails to build with Python 3.14.05. + help2man --no-info '--name=Spikesort a dataset' --version-string=3.0.16 --output=/builddir/build/BUILD/python-klusta-3.0.16-build/BUILDROOT/usr/share/man/man1/klusta.1 /builddir/build/BUILD/python-klusta-3.0.16-build/BUILDROOT/usr/bin/klusta help2man: can't get `--help' info from /builddir/build/BUILD/python-klusta-3.0.16-build/BUILDROOT/usr/bin/klusta 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_64/08651033-python-klusta/ For all our attempts to build python-klusta with Python 3.14, see: https://copr.fedorainfracloud.org/coprs/g/python/python3.14/package/python-klusta/ 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.
The root cause is h5py failing to import, bug 2345536. # PYTHONPATH=/builddir/build/BUILD/python-klusta-3.0.16-build/BUILDROOT/usr/lib/python3.14/site-packages/ /builddir/build/BUILD/python-klusta-3.0.16-build/BUILDROOT/usr/bin/klusta --help Traceback (most recent call last): File "/builddir/build/BUILD/python-klusta-3.0.16-build/BUILDROOT/usr/bin/klusta", line 5, in <module> from klusta.launch import main File "/builddir/build/BUILD/python-klusta-3.0.16-build/BUILDROOT/usr/lib/python3.14/site-packages/klusta/launch.py", line 18, in <module> from .traces import SpikeDetekt File "/builddir/build/BUILD/python-klusta-3.0.16-build/BUILDROOT/usr/lib/python3.14/site-packages/klusta/traces/__init__.py", line 9, in <module> from .spikedetekt import SpikeDetekt File "/builddir/build/BUILD/python-klusta-3.0.16-build/BUILDROOT/usr/lib/python3.14/site-packages/klusta/traces/spikedetekt.py", line 21, in <module> from ..kwik.mea import (_channels_per_group, _probe_adjacency_list, ) File "/builddir/build/BUILD/python-klusta-3.0.16-build/BUILDROOT/usr/lib/python3.14/site-packages/klusta/kwik/__init__.py", line 6, in <module> from .creator import KwikCreator, create_kwik File "/builddir/build/BUILD/python-klusta-3.0.16-build/BUILDROOT/usr/lib/python3.14/site-packages/klusta/kwik/creator.py", line 14, in <module> from h5py import Dataset File "/usr/lib64/python3.14/site-packages/h5py/__init__.py", line 45, in <module> from ._conv import register_converters as _register_converters, \ unregister_converters as _unregister_converters File "h5py/_conv.pyx", line 1, in init h5py._conv File "h5py/h5r.pyx", line 1, in init h5py.h5r File "h5py/h5p.pyx", line 1, in init h5py.h5p File "h5py/h5t.pyx", line 289, in init h5py.h5t File "h5py/h5t.pyx", line 281, in h5py.h5t._get_available_ftypes ValueError: chr() arg not in range(0x110000)
I see a successful build in https://copr.fedorainfracloud.org/coprs/g/python/python3.14/build/8736650/, so I guess the h5py issue must have been resolved.
