Steve Dower added the comment: Well, I was trying not to resurrect this old issue, but looks like I did it accidentally. Hi there, old hands! We miss you :) We also figured out a new [l]stat() implementation on Windows that handles symlinks and junctions better, and also non-file types such

Martin v. Löwis added the comment: The purpose of Py_GetFileAttributesEx* is to wrap GetFileAttributesEx, on systems where it doesn't exist (Windows 95 in particular). If it doesn't exist, it is emulated; if it exists, it is directly called. -- nosy: +loewis

Kevin Dwyer added the comment: Ok, it seems that Python 2.5 implements two new functions Py_GetFileAttributesExA and Py_GetFileAttributesExW in posixmodule.c within the #ifdef MS_WINDOWS block that may return ERROR_INVALID_PARAMETER to os.stat, which will percolate WindowsError up to os.exists():
