python-img2pdf with Python 3.10, see: https://copr.fedorainfracloud.org/coprs/g/python/python3.10/package/python-img2pdf/ 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 3.10: https://copr.fedorainfracloud.org/coprs/g/python/python3.10/ Let us know here if you have any questions. Python 3.10 will be included in Fedora 35. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.10. 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.
Since the segfault occurs during import of pikepdf (at what time img2pdf_test.py only has imported pretty standard python packages) the root cause of this issue seems to lie outside of img2pdf: + /usr/bin/python3 -m pytest src/img2pdf_test.py -k 'not test_png_icc and not test_tiff_ccitt_nometa2' Fatal Python error: Segmentation fault Current thread 0x00007fae2c668740 (most recent call first): File "<frozen importlib._bootstrap>", line 241 in _call_with_frames_removed File "<frozen importlib._bootstrap_external>", line 1125 in create_module File "<frozen importlib._bootstrap>", line 581 in module_from_spec File "<frozen importlib._bootstrap>", line 684 in _load_unlocked File "<frozen importlib._bootstrap>", line 1005 in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 1026 in _find_and_load File "<frozen importlib._bootstrap>", line 241 in _call_with_frames_removed File "<frozen importlib._bootstrap>", line 1077 in _handle_fromlist File "/usr/lib64/python3.10/site-packages/pikepdf/__init__.py", line 15 in <module> File "<frozen importlib._bootstrap>", line 241 in _call_with_frames_removed File "<frozen importlib._bootstrap_external>", line 832 in exec_module File "<frozen importlib._bootstrap>", line 698 in _load_unlocked File "<frozen importlib._bootstrap>", line 1005 in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 1026 in _find_and_load File "/builddir/build/BUILD/img2pdf-0.4.0/src/img2pdf_test.py", line 10 in <module> That means either there is an issue in the pikepdf module initialization or there is a bug in the general python import code. So what about re-assigning this issue then?
Elliot, can you take a look here regarding pikepdf?
I'm not sure how it could be pikepdf itself. It seems more likely to be something about the Python/C++ interface from pybind11. Can you get a backtrace?
I see succesful builds in https://copr.fedorainfracloud.org/coprs/g/python/python3.10/package/python-img2pdf/ -- let's assume this was a transient issue. Sorry for the noise.
