Subject: [PATCH] 00251: Change user install location
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Change the values of sysconfig's "posix_prefix" install scheme to /usr/local
when RPM build or venv/virtualenv is not detected,
to make pip, sysconfig and distutils install into an isolated location.
Set values of base and platbase in sysconfig from /usr
to /usr/local when RPM build is not detected
to make pip and similar tools install into separate location.
The original values are saved as an additional "rpm_prefix" install scheme.
The site module adds the /usr/local paths to sys.path when site packages are
enabled and RPM build is not detected.
Set values of prefix and exec_prefix in distutils install command
to /usr/local if executable is /usr/bin/python* and RPM build
is not detected to make distutils and pypa/distutils install into separate location.
Fedora Change: https://fedoraproject.org/wiki/Changes/Making_sudo_pip_safe
Downstream only.
Rewrote in Fedora 36+ to patch sysconfig instead of distutils,
see https://discuss.python.org/t/pep-632-deprecate-distutils-module/5134/104
We've tried to rework in Fedora 36/Python 3.10 to follow https://bugs.python.org/issue43976
but we have identified serious problems with that approach,
see https://bugzilla.redhat.com/2026979 or https://bugzilla.redhat.com/2097183
Downstream only for now, waiting for https://bugs.python.org/issue43976
pypa/distutils integration: https://github.com/pypa/distutils/pull/70
