New submission from Vlad Shcherbina:
When directory exists with a name chosen for new temporary file, OSError with
EACCESS errno is thrown on windows, while attempts to chose another name only
happen on EEXIST errors.
To reproduce, run
--------------- 8< -----------------
import sys
import tempfile
import os
print sys.platform
print sys.version
# Mock random names to ensure collision.
tempfile._RandomNameSequence = lambda: iter(['a', 'a', 'b'])
d = tempfile.mkdtemp()
print d
try:
print tempfile.NamedTemporaryFile().name
finally:
os.rmdir(d)
--------------- >8 -----------------
Expected result:
win32
2.7.3 (default, Apr 10 2012, 23:24:47) [MSC v.1500 64 bit (AMD64)]
...\tmpa
...\tmpb
Actual result:
win32
2.7.3 (default, Apr 10 2012, 23:24:47) [MSC v.1500 64 bit (AMD64)]
