coccinelle fails to build with Python 3.10.0a4. /lib64/libpython3.10.so.1.0 returned Cannot resolve _Py_fopen bpo-32381: Remove the private _Py_fopen() function which is no longer needed. Use _Py_wfopen() or _Py_fopen_obj() instead. https://docs.python.org/3.10/whatsnew/changelog.html#c-api For the build logs, see: https://copr-be.cloud.fedoraproject.org/results/@python/python3.10/fedora-rawhide-x86_64/01859535-coccinelle/ For all our attempts to build coccinelle with Python 3.10, see: https://copr.fedorainfracloud.org/coprs/g/python/python3.10/package/coccinelle/ 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.

Hmm, I thought I fixed the Python 3.10 things (bug 1896393). Or is Python 3.10 still in development? Anyway this fix is a bit beyond me. Replacing the call with _Py_wfopen appears like it will work, but what I'm not sure is why on earth the code is calling these internal python functions in the first place instead of using regular fopen. Indeed for Python 2 it *was* using regular fopen. I will ask upstream.

This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle. Changing version to 34.
