PyPAM fails to build with Python 3.11.0a2.

PAMmodule.c: In function ‘PyPAM_conv’:

Since Py_TYPE() is changed to a inline static function, Py_TYPE(obj) = new_type must be replaced with Py_SET_TYPE(obj, new_type): see the Py_SET_TYPE() function (available since Python 3.9). For backward compatibility, this macro can be used:

#if PY_VERSION_HEX < 0x030900A4 && !defined(Py_SET_TYPE)
static inline void _Py_SET_TYPE(PyObject *ob, PyTypeObject *type)
{ ob->ob_type = type; }
#define Py_SET_TYPE(ob, type) _Py_SET_TYPE((PyObject*)(ob), type)

For all our attempts to build PyPAM with Python 3.11, 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 3.11:

Let us know here if you have any questions.

Python 3.11 is planned to be included in Fedora 37. To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.11.
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.

Comment 1 Fedora Admin user for bugzilla script actions 2021-11-11 00:04:24 UTC
This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component.

Comment 2 Miro Hrončok 2021-12-23 14:19:29 UTC
Automation has figured out the package is retired in rawhide.

If you like it to be unretired, please open a ticket at https://pagure.io/releng/new_issue?template=package_unretirement
