[issue3748] [py3k] platform.architecture() prints vogus messege on windows

[Hirokazu Yamamoto]

Hirokazu Yamamoto [EMAIL PROTECTED] added the comment:

This difference between trunk and py3k would go down to this.

import os
os.popen(r'file e:\python-dev\py3k\PC\VC6\python_d.exe 2 /dev/null')

trunk prints nothing, but py3k prints that message.

I don't know which is popen's correct behavior, we can supress this
message by using subprocess.Popen instead.

Amaury Forgeot d'Arc [EMAIL PROTECTED] added the comment:

The call to _syscmd_file() should be avoided on windows platforms:
- the file program does not exist
- the stderr is redirected to /dev/null, which does not necessarily exists!

On my machine, there is a c:\dev directory. Now it contains a file
named null, which content is 'file' is not recognized as an internal
or external command, operable program or batch file.
No comment.
