Fixes #2102

On Windows during interpreter shutdown, process objects can be partially torn down and terminate() may raise AttributeError (e.g. missing TerminateProcess).

This PR treats that similarly to the existing OSError handling in _AutoInterrupt._terminate() and adds a regression test covering the AttributeError case.

Tests: pytest -q test/test_autointerrupt.py

I've made two changes:

  • Rebased this onto main after merging #2108 to fix #2107 (which arose more recently than #2105 (review) and is not due to changes here, but would have appeared here next time CI ran).
  • Fixed the blocker mentioned in #2105 (review) where the lint job failed. This was due to an unnecessary import pytest (since the module does not use anything from the pytest module in its own code).

I plan to merge this once CI passes.

Pull request overview

Fixes a Windows interpreter-shutdown edge case where Git.AutoInterrupt._terminate() can raise AttributeError from subprocess.Popen.terminate() due to partially torn-down stdlib internals, preventing noisy “Exception ignored in: del” messages.

Changes:

  • Treat AttributeError from proc.terminate() similarly to existing OSError handling in _AutoInterrupt._terminate().
  • Add a regression test that simulates terminate() raising AttributeError and asserts _terminate() does not raise and clears proc.
