[issue13195] subprocess: args with shell=True is not documented on Windows

[Martin Panter]

Martin Panter added the comment:

I think the documentation changes made for Issue 16115 should address your 
first question (shell=False). For shell=True, see the discussion at Issue 
20344. Perhaps you can review my patch.

[issue13195] subprocess: args with shell=True is not documented on Windows

[anatoly techtonik]

New submission from anatoly techtonik techto...@gmail.com:

For UNIX, it is said that if shell=False then you need to pass `args` as a list 
(if you want to pass any parameters to executable). Is that true for Windows 
(and perhaps other platforms) as well?

Again, for UNIX it is said that with shell=True, and args is a list - every 
item except the first one is an argument to the shell itself. Is it the same on 
Windows?


It would be better to just give advice in `shell` parameter description to 
pass args as a list with shell=False or else you'll lose params in Unix. If 
shell=True you need to pass args as a string, because list is needed only if 
you need to pass arguments to shell itself.

Looks like a can of worms. For now I'll be pretty fine if this stuff is at 
least properly documented.

Can you propose a document patch describing the current behaviour?

Certainly not right now as I don't have development environment setup. Perhaps 
in a few days if somebody pings me. It could be a lot easier with online 
editor, of course - http://code.google.com/p/pydotorg/issues/detail?id=6

See our development guide to get such environment:

Would like like to work on this project? (provide an online editor)

I know. There is better tool at
https://bitbucket.org/techtonik/devinabox but I have only 500Mb left
on my system drive and there are still more problems I need to handle.

Do you mean would I like to work on it? Actually, I made a prototype
on AppEngine that waits for JS guru to tune CodeMirror interface. If
somebody is interested to help, I've just uploaded the code to
http://code.google.com/p/pydotorg/source/browse/?repo=doceditor
