List not only needs to be joined, it should be quoted as well. But the biggest 
problem will be the change of behavior between Python versions which may 
confuse users even more.

Perhaps it's a good time to start embedding 'best practice' recipes in manual.

Raymond Hettinger raymond.hettin...@gmail.com added the comment:

I don't think you can tighten the API at this point.  We could however make 
Popen complain when options are going to be thrown away.  Or it could be made 
more liberal about what is accepts (running shlex on string input or join on 
list input as needed).

[issue13197] subprocess: move shell arguments to a separate keyword param

2011-10-17 Thread anatoly techtonik 

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

subprocess.Popen(args, shell=shell) is implicitly inconsistent on Unix:
 1. when shell=False, the args should be a list or you'll lose program options
 2. when shell=True, the args should be a string or your program options will 
be passed to shell itself


I propose to make consistent behaviour - require args to be a list, and pass 
shell options in a separate shell_args keyword argument. If it not for python4, 
then perhaps it can be implemented in PopenShell() and PopenSystem() functions.

This will also require unification of behaviour across platforms.

No. I won't be fixed in 2.7 anyway, and if it can not be fixed, it should be 
documented at least.

Oh, sorry - my attention span is limited under time pressure. #7839 is related, 
of course. There is a lot of comments, so I'll take a look at it later.
