python-pyside2 fails to build with Python 3.10.0a2.
/sources/shiboken2/libshiboken/sbkstring.cpp:250:23: error: expression is not assignable
Py_REFCNT(ob) = 1;
1 error generated.
bpo-39573: Convert Py_REFCNT() and Py_SIZE() macros to static inline functions. They cannot be used as l-value anymore: use Py_SET_REFCNT() and Py_SET_SIZE() to set an object reference count and size. This change is backward incompatible on purpose, to prepare the C API for an opaque PyObject structure.

For all our attempts to build python-pyside2 with Python 3.10, see:
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:
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.
Victor, please take a look.
I'm working on a fix: https://src.fedoraproject.org/rpms/python-pyside2/pull-request/7
I reported the issue to Qt upstream (PySide project): https://bugreports.qt.io/browse/PYSIDE-1436
Upstream is having a very active discussion on the fix so I would rather wait for them than apply the patch which just makes it "build".
Hopefully they'll provide a patch (or something that I can make a patch from) and we won't have to wait until the next patch release.
This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle.
Changing version to 34.
