libxml2 fails to build with Python 3.10.0a1. make[2]: Leaving directory '/builddir/build/BUILD/libxml2-2.9.10/py3/python/tests' test.xml:1: parser error : Couldn't find end of Start Tag foo <foo ^ SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/builddir/build/BUILD/libxml2-2.9.10/py3/python/tests/../../../python/tests/push.py", line 9, in <module> ctxt.parseChunk("/>", 2, 1) File "/builddir/build/BUILD/libxml2-2.9.10/python/libxml2.py", line 5101, in parseChunk ret = libxml2mod.xmlParseChunk(self._o, chunk, size, terminate) SystemError: <built-in function xmlParseChunk> returned a result with an error set For the build logs, see: https://copr-be.cloud.fedoraproject.org/results/@python/python3.10/fedora-rawhide-x86_64/01715877-libxml2/ For all our attempts to build libxml2 with Python 3.10, see: https://copr.fedorainfracloud.org/coprs/g/python/python3.10/package/libxml2/ 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.

I reported the issue to upstream: https://gitlab.gnome.org/GNOME/libxml2/-/issues/203 And I proposed a fix: https://gitlab.gnome.org/GNOME/libxml2/-/merge_requests/87
I proposed to https://src.fedoraproject.org/rpms/libxml2/pull-request/10 to backport my fix and fix the package (always regenerate the 3 Python generated files).

Hi, I've encountered this issue on Fedora 35 container. This issue occurs when I try to build the module build for RHEL-8 using this command: rhpkg module-build --scratch --buildrequires platform:el8.5.0 The Fedora container that I'm using is here: https://gitlab.cee.redhat.com/platform-eng-core-services/core-services-dockerfiles/-/tree/master/pkg-container Error message: Could not execute module_build: PY_SSIZE_T_CLEAN macro must be defined for '#' formats PS: I've tried it in the Fedora 34 container and it worked as expected, so the issue must be in the commits between these two versions Reopening this BZ, if you prefer to create a new one let me know.
I am not sure that gitlab.cee link works outside of the Red Hat network and this is Fedora Bugzilla. Could you provide a more accessible reproducer, please? Also, what makes you think that the error comes from libxml2?
A list of installed packages (including their versions, releaes and architecture) would be helpful to determine what packages could cause this. Could you please attach the output of `rpm -qa`? Also, is there a way to see the full traceback?
> Also, is there a way to see the full traceback? Please, run again with rhpkg --debug. That raises the exception instead of hiding it: except Exception as e: ... if getattr(client.args, 'debug', False): raise log.error('Could not execute %s: %s' % (client.args.command.__name__, e)) sys.exit(1)
