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.
This is a mass-posted update. Sorry if it is not 100% accurate to this bugzilla. The Python 3.10 rebuild is in progress in a Koji side tag. If you manage to fix the problem, please commit the fix in the rawhide branch, but don't build the package in regular rawhide. You can either build the package in the side tag, with: $ fedpkg build --target=f35-python Or you can the build and we will eventually build it for you. Note that the rebuild is still in progress, so not all (build) dependencies of this package might be available right away. Thanks. See also https://fedoraproject.org/wiki/Changes/Python3.10 If you have general questions about the rebuild, please use this mailing list thread: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/thread/G47SGOYIQLRDTWGOSLSWERZSSHXDEDH5/
This is fixed upstream, but we might have to update coccinelle or backport the upstream patch. Mailing list thread: https://lore.kernel.org/cocci/ow4mtxjyqhx.fsf@inria.fr/
I've now actually checked and it seems cocci was rebuilt successfully: https://koji.fedoraproject.org/koji/buildinfo?buildID=1759679 against: DEBUG util.py:446: python3-devel x86_64 3.10.0~b2-3.fc35 build 205 k so there should be nothing to do here.
