Crashes with Python 3.13 b2 #11

Open alebastr opened 1 week ago

alebastr commented 1 week ago

The following example crashes with Python 3.13.0b2 (python3-3.13.0~b2-3.fc41.x86_64):

#!/usr/bin/python3
from unittest import TestCase

from kgb import SpyAgency

def outer(arg):
    # required to reproduce the crash
    def _inner_unused():
        # must be a closure to repro
        print(arg)

    return 1

class CrashTest(SpyAgency, TestCase):

    def test(self):
        self.spy_on(outer)
        outer(1)

if __name__ == '__main__':
    t = CrashTest()
    t.test()

(originally reproduced and extracted from the RBTools test suite)

Should be reliably reproducible in a fresh fedora:rawhide container.

I suspect that some changes in 3.13 weren't compatible with the way kgb works and require corresponding fixes here. I suppose this could be a Python bug instead, but even in that case I won't be able to debug that and will need your help.

chipx86 commented 1 week ago

Thanks for the report! Shame this is busted...

My initial hunch is that it has to do with the new locals() changes (https://peps.python.org/pep-0667/). Of course, it could be something else (JIT stuff, maybe?).

I'm going to need to spend some time figuring out exactly how this would impact bytecode mutation, and whether a workaround is possible.

chipx86 commented 1 week ago

Yeah, it's locals handling. Any call to locals() within our compiled function breaks. This indicates a problem building our CodeType, which may help narrow down the cause.

chipx86 commented 1 week ago

Testing a fix.

chipx86 commented 1 week ago

Can you test the attached patch locally?

0001-Fix-a-crash-when-accessing-locals-on-Python-3.13.patch

alebastr commented 1 week ago

Thanks!

The patch works for me both locally and in the package build environment.

chipx86 commented 1 week ago

Thanks for testing that so quickly!

I want to hold off on any release until 3.13 is further along (we haven't begun any official testing on 3.13 yet), in case anything regresses from this fix. We'll want to test it a while for existing releases. Would this be a blocker for you?

alebastr commented 1 week ago

That is fine, I'll just skip the testcase in the RBTools package spec and reenable it when we get a fix. No other packages were affected so we can wait.

chipx86 commented 4 days ago

Sounds good. Out of curiosity, is this for a Linux distro, or in-house build management?

alebastr commented 4 days ago

It's for Fedora Linux. I took ownership of the RBTools package a few months ago.
