@graingert as the author of several of the tests in test_unraisableexception.py

[graingert]

Looks like the message changed from "Exception ignored in" to "Exception ignored while calling deallocator "

[graingert]

the urllib HTTPErrors are actually also files and need an explicit with or .close()

[graingert]

and looks like we've got a 3.14 error as unraisable_arg.object is not being set for unraisablehook:

import gc
import sys

class Foo:
    def __del__(self):
        raise ValueError("__del__ is broken")


def main():
    v = None
    def unraisablehook(unraisable_arg):
        nonlocal v
        v = unraisable_arg

    sys.unraisablehook = unraisablehook
    Foo()
    gc.collect()
    print(v.object)


if __name__ == "__main__":
    sys.exit(main())

[graingert]

see python/cpython#134732 looks like an intentional change not to pass object to unraisablehook

[jakkdl]

#13440 is marking testing.test_debugging.test_raises_bdbquit_with_eoferror as xfail. While I don't think we care about bdbquit in itself, there's a change in behavior where Ctrl-D/EOFError now behaves like quit and we get the test marked as not being run, rather than failing. I'm not sure if we can disambiguate quit from EOFError on py314, or if we should harmonize quit and EOFError to behave in the same way on py<314. And if so, do users prefer quitting the test session completely on Ctrl-D, or do we want quitting a test to become failing the test?

(I personally often ended up adding -x because I wanted to quit the session after debugging a test case and was not aware I could use quit, so I would vote for the former)

[nicoddemus]

And if so, do users prefer quitting the test session completely on Ctrl-D, or do we want quitting a test to become failing the test?

I also think Ctrl-D should quit the test session.

[graingert]

Shall we leave this open until a decision is reached about test_raises_bdbquit_with_eoferror?

[RonnyPfannschmidt]

Let's create a followup issue to sort that particular detail

[nicoddemus]

Let's create a followup issue to sort that particular detail

Agreed, done: #13453.

Closing this as fixed then, thanks @graingert!

[hroncok]

Folks. I just wanted to belatedly say: Thank you!
