[New-bugs-announce] [issue1311] os.path.exists(os.devnul) regression on windows

[David Kågedal]

New submission from David Kågedal:

When moving from Python 2.4 to Python 2.5, my program stopped working on
win32 because of a change in os.path.exists. I couldn't find any
description of the change, so I can only assume it's a bug.

The os.devnul variable contains the name of the "null file", which is
"/dev/null" on posix, and "nul" on win32. As I understand it, "NUL" is a
file that exists in every directory on win32.

Opening the "nul" file with open("nul", "r") works fine, but
os.path.exists("nul") returns False. In Python 2.4, it returns True.
