Feature or enhancement

Proposal:

Currently, a ValueError is raised by the path_t converter if the input path is too long or if there are embedded null bytes. For any C code that is using this converter, such as os.stat, this actually makes os.stat raise a ValueError instead of an OSError in this case.

EDIT: Remove paragraph on NUL bytes. For NUL bytes, the converter must anyway raise ValueError. I fixed linecache in #122176 for that.

See #122170 (comment) for another issue (only on Windows though I don't know why since Linux may also have too long paths in general).

So, what I suggest is to raise OSError, or have a way to only disable ValueError that would not make stat(2) fail (i.e., keep ValueError for NUL bytes but not for long paths). I don't know which is the best but I'd prefer just ignoring long paths in path_t converter itself.
