New submission from Łukasz Langa <luk...@langa.pl>: >>> class K: ... def __fspath__(self): ... return 1 ... >>> import os >>> os.stat(K()) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: stat: path should be string, bytes, os.PathLike or integer, not int
This error message is internally inconsistent: - it suggests that the error is about the path argument whereas it's in fact about the value returned from `__fspath__()` - it hilariously states "should be integer, not int" - it claims os.PathLike is fine as a return value from `__fspath__()` whereas it's not I would advise removing the custom `__fspath__()` handling from `path_converter` and just directly using PyOS_FSPath which returns a valid error in this case (example from pypy3): >>>> class K: .... def __fspath__(self): .... return 1 .... >>>> import os >>>> os.open(K(), os.O_RDONLY) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: expected K.__fspath__() to return str or bytes, not int ---------- messages: 335094 nosy: lukasz.langa priority: normal severity: normal stage: needs patch status: open title: posixmodule.c:path_converter() returns an invalid exception message for broken PathLike objects type: behavior versions: Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35942> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
