Various tests failures on Python 3.12.0rc1

Commencez par reproduire les échecs listés avec Python 3.12.0rc1, puis lisez tests/test_archive.py et tests/test_extractcode_cli.py, y compris leur helper run_extract et les cas d’archive en échec. Le travail est terminé lorsque les causes liées à Python 3.12 sont identifiées et que tous les tests listés passent dans l’environnement Fedora indiqué.

Environment:

• Python 3.12.0rc1
• Fedora Rawhide
• libmagic 5.45
• libarchive 3.7.1
• p7zip 16.02
