- The python-unversioned-command package is no longer Python 2, but 3
- The python, pydoc, python-config, python-debug, idle, pygettext.py and
msgfmt.py commands are now in python3
This allows easier compatibility back and forth once (and if)
https://fedoraproject.org/wiki/Changes/Python_means_Python3
happens. This is not the full implementation of the change,
as the python-unversioned package still needs to be added.
This is currently a no-op as %python_provide does nothing
for python3.
Since 2012, when the test was skipped from Python 3.3.0b1 (commit
3b4dd24c42), Linux now have a good
support for punching holes in filesystems.
Only 00160-disable-test_fs_holes-in-rpm-build.patch and
00163-disable-parts-of-test_socket-in-rpm-build.patch patches used
@unittest._skipInRpmBuild @unittest._expectedFailureInRpmBuild
decorators, but these 2 patches have been removed: remove
00132-add-rpmbuild-hooks-to-unittest.patch and
WITHIN_PYTHON_RPM_BUILD environment variable as well.
In diff order:
- gdbm releases in all Fedoras are long above 1:1.13
- the flat package should be called python3.7 but we are lazy to rename
- system-python is long gone, upgrade path works
- python3-enum34 is only required by 2 pkgs [0][1]
- glibc releases in all Fedoras are long above 2.24.90-26
Not removed:
- platform-python obsoletes shall be removed in Fedora 31, they were added in 28

Such files are only used to create Microsoft Windows installers
and that functionality is broken on Linux anyway.
We can keep the exe files in SRPM, as they are free software as
confirmed by the Python Software Foundation:
> Hello,
>
> Shipping and distributing these files is ok.
>
> These files are stubs, used as the executable part of a self-unzipping
> executable and showing an "installer window" to the user.
> They are original to Python and, while they call win32 functions,
> they don't have Windows SDK code in them.
> The source is at: PC/bdist_wininst/install.c
>
> The binaries are included so that anyone creating a bdist_wininst
> distribution (mostly deprecated, actually) can do so, even when
> cross-compiling.

> Thanks,

Python 3 test suite requires various locales. Install all of them to
build the package to make sure that no test is skipped because of a
missing locale.
- rename it, the are no pyo files on Python 3
- make sure to check all levels of pyc files optimization
- use path globs
- use comprehensions instead of map + filter
- use f-strings and print() instead of sys.stderr.write()
