Summary: subprocess swallows empty arguments under win32
Initial Comment:
Hello,
empty arguments are not quoted by subprocess.list2cmdline. Therefore nothing is
concatenated with other arguments. To reproduce it:
test-empty.py
"""
import sys
print sys.argv
"""
then:
"""
Python 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import subprocess
>>> p = subprocess.Popen(['python', 'test-empty.py', ''],
>>> stdout=subprocess.PIPE)
>>> p.communicate()
("['test-empty.py']\r\n", None)
"""
To solve it:
