Before:
$ python3.14 -m timeit -s 'import sysconfig' 'sysconfig.get_paths()'
2000 loops, best of 5: 157 usec per loop
$ python3.14 -m timeit -s 'import sysconfig' 'sysconfig.get_paths()'
2000 loops, best of 5: 162 usec per loop
$ python3.14 -m timeit -s 'import sysconfig' 'sysconfig.get_paths()'
1000 loops, best of 5: 146 usec per loop
After:
$ python3.14 -m timeit -s 'import sysconfig' 'sysconfig.get_paths()'
5000 loops, best of 5: 75.9 usec per loop
$ python3.14 -m timeit -s 'import sysconfig' 'sysconfig.get_paths()'
5000 loops, best of 5: 77.1 usec per loop
$ python3.14 -m timeit -s 'import sysconfig' 'sysconfig.get_paths()'
5000 loops, best of 5: 76.2 usec per loop
The results are inconclusive on 3.13,
but we want the patch to be identical (if possible).
This can be shipped with the next update.
This is for https://fedoraproject.org/wiki/Changes/Separate_dtrace_package
This already BuildRequired /usr/bin/dtrace, but it also needs the headers:
In file included from /builddir/build/BUILD/python3.13-3.13.0_b4-build/Python-3.13.0b4/Include/pydtrace.h:11,

compilation terminated.
- bzip2 is not used directly, only via bzip2-devel
- tar is not used directly either, %autosetup uses rpmuncompress
- desktop-file-utils is only used to install idle desktop file with main_python
- libappstream-glib is only used to validate idle appdata file with main_python
- /usr/sbin/ifconfig is no longer needed for test_uuid
- gcc-c++, glibc-all-langpacks, tzdata are only used in tests
(although something pulls in tzdata even with bootstrap without tests, so this one is hard to verify)
- gmp-devel in not needed since Python 2.4 (mpz module was removed)
- libGL-devel appears unused (and hard to find why it ever was needed)

The code in CPython uses XML_SetReparseDeferralEnabled when expat is >= 2.6 during the build.
However, when users upgrade Python independently on the expat package,
they may have expat 2.5 installed and see errors like:
$ python3.1X -m venv venv
Error: Command '['venv/bin/python3.1X', '-m', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.
$ venv/bin/python3.1X -m ensurepip --upgrade --default-pip

mimalloc provide is only declared in -libs subpackage, although
it's present also in -devel, -debug, -freethreading and
-freethreading-debug. All of those effectively require -libs, so
duplicating the provide accross all those was deemed unnecessary.
Patch 00371 was removed as it no longer applies after
33da0e844c
We need to monitor the freeipa situation and rework the patch entirely in
case it is still needed.
