Platform: Python 2.5b1 Windows XP Bug: os.access will report that a user doesn't have write permissions to a file or directory when the user actually does. Reproducibility: always This is being run on an administrator account. >>> import os >>> os.access("C:\\", os.W_OK) False >>> os.access("C:\\test.txt", os.W_OK) False I have also checked that Python can indeed write to the file.

Logged In: YES user_id=33168 Does this problem only occur with 2.5 or is it also present in 2.4?

Logged In: YES user_id=1081617 Yeah, it's only 2.5, and only 2.5b1. Basically, there's a double ampersand used instead of a single ampersand in posixmodule.c. I've attached the patch.

Logged In: YES user_id=33168 Your change looks correct, but I would really like a test case to fix this problem. I don't have access to a Windows box, so I can't verify the test fails before this patch and succeeds with it. Can you create a test case too? The best place to add the test would be Lib/test/test_posix.py. Thanks!

Logged In: YES user_id=1081617 Cool. I added the new patch with the test case.

Logged In: YES user_id=21627 Thanks for the report and the patch, committed as r47198 (I moved the test in a separate class, though).
