We hardcode the xy prefix we want to obsolete to "39", because:
1. Python 3.9 will remain the main Python versin in RHEL 9
2. python39 in RHEL 8 is still using the dotless naming (as opposed to
python3.9)
Resolves: rhbz#1990421
I.e. when %python3_pkgversion is 3.12, %__python3 is /usr/bin/python3.12
We assume that when packagers package for Python 3.X, they want to change both
%python3_pkgversion and %__python3 value.
Hence instead of copy-pasting this:
%global python3_pkgversion 3.X
%global __python3 /usr/bin/python3.X
They just need to do:
%global python3_pkgversion 3.X
Packagers who want to change the value of %__python3 without touching
%python3_pkgversion can still do it:
%global __python3 /usr/bin/pypy3

%%py{3}_check_import now respects the custom setting of %%py{3}_shebang_flags
and invokes Python with the respective values.
If %%py{3}_shebang_flags is undefined or set to no value,
there no flags are passed to Python on invoke.

-f: optionally read a file with module names to test
-t: bool flag - if set, filter only top-level modules
-e: optionally exclude module names matching the given glob (Unix
shell-style wildcards)
Importing all modules may cause bogus failures in some cases,
eg. when the imported code assumes there is an existing graphical window.
Such behaviour may be by design, hence for automatic processing it's
more convinient to - in some cases - check only for top-level modules
or filter out the troublemakers.

With $PATH and $PYTHONPATH set to the %buildroot,
the macro tries to import the given Python 3 module(s).
Useful as a smoke test in %check when ruining tests is not feasible.
Accepts spaces or commas as separators.
Package python-six:
%check
%py3_check_import six

%py3_check_import six seven
...

Traceback (most recent call last):

Distutils which were used to define the macros are deprecated in Python3.10:
https://www.python.org/dev/peps/pep-0632/.
Sysconfig isn't and it works across our Pythons, making it better choice for the task.

This allows e.g.:
%global extras cli,ghostwriter,pytz,dateutil,lark,numpy,pandas,pytest,redis,zoneinfo,django
%{pyproject_extras_subpkg -n python3-hypothesis %{extras}}
...
%pyproject_buildrequires -x %{extras}
(Note that %pyproject_extras_subpkg is a tiny wrapper around %python_extras_subpkg.)
