[issue1311] os.path.exists(os.devnull) regression on windows

2007-10-23 Thread David Kågedal 

David Kågedal added the comment:

I tried it on two different machines, and got two different answers:

conan$ /cygdrive/c/Python25/python -c 'import os.path; print
os.path.exists("nul")'
False
conan$ /cygdrive/c/Python24/python -c 'import os.path; print
os.path.exists("nul")'
False

conan$ /cygdrive/c/Python24/python -c 'import os; print os.stat("nul")'
Traceback (most recent call last):
  File "", line 1, in ?
OSError: [Errno 22] Invalid argument: 'nul'
conan$ /cygdrive/c/Python25/python -c 'import os; print os.stat("nul")'
Traceback (most recent call last):
  File "", line 1, in 
WindowsError: [Error 87] The parameter is incorrect: 'nul'


titti$ /cygdrive/c/Python24/python -c 'import os.path; print
os.path.exists("nul")'
True
titti$ /cygdrive/c/Python25/python -c 'import os.path; print
os.path.exists("nul")'
False

titti$ /cygdrive/c/Python24/python -c 'import os; print os.stat("nul")'
(33206, 0L, 3, 1, 0, 0, 0L, -1, -1, -1)
titti$ /cygdrive/c/Python25/python -c 'import os; print
os.stat("nul")'Traceback (most recent call last):
  File "", line 1, in 
WindowsError: [Error 87] The parameter is incorrect: 'nul'

I ran it from a cygwin prompt, but the pythons are native.

So you are correct that it doesn't work as I expected in Python 2.4
either on the "conan" host..  On "titti", there is a difference in how
os.path.exist works between 2.4 and 2.5. On "conan" there is actually
also a difference, but only in the exception raised by os.stat.

I don't know what the differences between these installation are.

[issue1311] os.path.exists(os.devnull) regression on windows

It's called os.devnull, and nothing else.

[issue1311] os.path.exists(os.devnul) regression on windows

2007-10-22 Thread 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.
