Subject: [PATCH] 00353: Original names for architectures with different names
|

downstream

|
|
|
|
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.
