New submission from Alexey Izbyshev <izbys...@ispras.ru>: > python ัะตัั.pyc python: Can't reopen .pyc file
The issue is caused by _Py_fopen() being used as though it can deal with paths encoded in FS-default encoding (UTF-8 by default on Windows), but in fact it's just a simple wrapper around fopen() from the C runtime, so it uses the current ANSI code page, breaking if PYTHONLEGACYWINDOWSFSENCODING is not enabled. I could find only two callers if _Py_fopen() on Windows: * https://github.com/python/cpython/blob/db68544122f5/Python/pythonrun.c#L380 (which caused this issue) * https://github.com/python/cpython/blob/db68544122f5/Python/errors.c#L1708 PyErr_ProgramText() doesn't seem to be called in CPython, but https://github.com/python/cpython/blob/db68544122f5/Include/pyerrors.h#L243 claims that filename is "decoded from the filesystem encoding", which doesn't match the code. ---------- components: Interpreter Core, Windows messages: 382490 nosy: izbyshev, paul.moore, steve.dower, tim.golden, vstinner, zach.ware priority: normal severity: normal status: open title: Python can't run .pyc files with non-ASCII path on Windows type: behavior versions: Python 3.10, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42568> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
