• gh-140860: Clear audit hooks before destroying modules #140861

[StanFromIreland]

Any error will trigger, e.g.:

import sys
import time

time_tuple = time.localtime()

def hook(event, *args):
    pass
sys.addaudithook(hook)

raise ValueError

I'm guessing something to do with the time module.

[StanFromIreland]

Oh, it's just the audithook preventing proper clean up, simplified repro:

import sys
import time

time_tuple = time.localtime()

def hook(event, *args):
    pass
sys.addaudithook(hook)
pass

[efimov-mikhail]

Even without errors we have the same result:

import sys
import time

hook = lambda a, b: None
sys.addaudithook(hook)
t = time.localtime()

I can reproduce this issue with ASAN on 3.14 and main, and not on 3.13.

[StanFromIreland]

I have a patch to clear audit hooks before destroying modules to avoid reference cycles, fixes the issue.

[StanFromIreland]
