I also saw the error with 305612d1b04aa06d3d1a1c8b51d046a644742fd5, so I reverted that too:

commit 305612d1b04aa06d3d1a1c8b51d046a644742fd5
Author: Zac Medico <zmedico@gentoo.org>
Date:   2024-02-03 13:27:45 -0800

    process.spawn: Use multiprocessing.Process for returnproc
    
    Use multiprocessing.Process for returnproc, so that
    fork will stop being used when python makes "spawn"
    the default multiprocessing start method.
    
    Continue to use _start_fork when returnproc is not
    enabled, for backward compatibility. Ultimately,
    it can be removed at the same time as the returnpid
    parameter.

It looks like I reverted 6aeee45d9b88d7dc8c450ba86975e4b017db203c prematurely, since I don't see an error with that and not 305612d1b04aa06d3d1a1c8b51d046a644742fd5.

It looks like we probably need more os.set_inheritable calls to make 305612d1b04aa06d3d1a1c8b51d046a644742fd5 work correctly, like the lib/portage/tests/ebuild/test_doebuild_fd_pipes.py change in that commit.

> How to repair?

Personally, I did:
git diff -p -b 6aeee45d9b8.. |sed -e 's^/lib/^/^g' > ~/fixportage.patch
cd /usr/lib/python3.11/site-packages
patch -p1 < ~/fixportage.patch

but it's potentially gonna depend what commit you were at previously

...and Sam's method is way easier
Comment 12 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-02-04 23:36:11 UTC
fwiw I'd be prepared to do what kurly did in future, it's just that in this case, there's a nice workaround
Comment 13 jospezial 2024-02-05 00:08:13 UTC
I found https://wiki.gentoo.org/wiki/Project:Portage/Fixing_broken_portage
based on that I did:

cd /var/tmp/portage/sys-apps/portage-9999/work/portage-9999/bin

export PYTHONPATH="/var/tmp/portage/sys-apps/portage-9999/work/portage-9999/lib${PYTHONPATH:+:}${PYTHONPATH}"

export PATH="/var/tmp/portage/sys-apps/portage-9999/work/portage-9999/bin:${PATH}"

emerge -va1 "<portage-9999"

That worked.
After logout and login into the shell to let it forget the exported PATH variables all is normal again.
sys-apps/portage-9999 is also working now.

Yeah, that's a great approach.

I've found that marking fd_pipes as inheritable just after fork solves the problem, but I think I might add a wrapper target function to do this just for _start_proc since it's only really needed when we exec for spawn:

    process.spawn: Use multiprocessing.Process for returnproc
    
    Use multiprocessing.Process for returnproc, so that
    fork will stop being used when python makes "spawn"
    the default multiprocessing start method.
    
    Continue to use _start_fork when returnproc is not
    enabled, for backward compatibility. Ultimately,
    it can be removed at the same time as the returnpid
    parameter.
    
    The _setup_pipes_after_fork wrapper prevents a
    "Bad file descriptor" error by making fd_pipes
    inheritable on exec for bug 923755. ForkProcess
    does not handle this because its target function
    does not necessarily exec.
