From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Lumir Balhar <lbalhar@redhat.com>

Subject: [PATCH] 00353: Original names for architectures with different names
downstream
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
https://fedoraproject.org/wiki/Changes/Python_Upstream_Architecture_Names
Pythons in RHEL/Fedora used different names for some architectures
than upstream and other distros (for example ppc64 vs. powerpc64).
This was patched in patch 274, now it is sedded if %with legacy_archnames.
That meant that an extension built with the default upstream settings
(on other distro or as an manylinux wheel) could not been found by Python
on RHEL/Fedora because it had a different suffix.
This patch adds the legacy names to importlib so Python is able
to import extensions with a legacy architecture name in its
file name.
It work both ways, so it support both %with and %without legacy_archnames.
WARNING: This patch has no effect on Python built with bootstrap
enabled because Python/importlib_external.h is not regenerated
and therefore Python during bootstrap contains importlib from
upstream without this feature. It's possible to include
Python/importlib_external.h to this patch but it'd make rebasing
a nightmare because it's basically a binary file.

commit 9e77ec82c40ab59846f9447b7c483e7b8e368b16
Author: Petr Viktorin <pviktori@redhat.com>
Date: Thu Mar 4 13:59:56 2021 +0100
CVE-2021-23336: Add `separator` argument to parse_qs; warn with default
Partially backports https://bugs.python.org/issue42967 : [security] Address a web cache-poisoning issue reported in urllib.parse.parse_qsl().
However, this solution is different than the upstream solution in Python 3.6.13.
An optional argument seperator is added to specify the separator.
It is recommended to set it to '&' or ';' to match the application or proxy in use.
The default can be set with an env variable of a config file.
If neither the argument, env var or config file specifies a separator, "&" is used
but a warning is raised if parse_qs is used on input that contains ';'.

# Original names for architectures with different names downstream
#
# https://fedoraproject.org/wiki/Changes/Python_Upstream_Architecture_Names
#
# Pythons in RHEL/Fedora used different names for some architectures
# than upstream and other distros (for example ppc64 vs. powerpc64).
# This was patched in patch 274, now it is sedded if %%with legacy_archnames.
#
# That meant that an extension built with the default upstream settings
# (on other distro or as an manylinux wheel) could not been found by Python
# on RHEL/Fedora because it had a different suffix.
# This patch adds the legacy names to importlib so Python is able
# to import extensions with a legacy architecture name in its
# file name.
# It work both ways, so it support both %%with and %%without legacy_archnames.
#
# WARNING: This patch has no effect on Python built with bootstrap
# enabled because Python/importlib_external.h is not regenerated
# and therefore Python during bootstrap contains importlib from
# upstream without this feature. It's possible to include
# Python/importlib_external.h to this patch but it'd make rebasing
# a nightmare because it's basically a binary file.
