[Python-Dev] "Deprecation" of os.system in favor of subprocess?


Good morning/afternoon/evening/night ;-)

In the documentation of os.system [1], there is this paragraph, where we
suggest to use subprocess instead of os.system.

"""
The subprocess module provides more powerful facilities for spawning new
processes and retrieving their results; using that module is preferable
to using this function. See the Replacing Older Functions with the
subprocess Module section in the subprocess documentation for some
helpful recipes.
"""

But I have found some references (between 15 and 23 (if we include
setup.py)) of os.system.


Do we need to keep the code like that or could we start to use
subprocess for these "references" because it is preferable?

If you think we could move to subprocess, I would like to open an issue
and try to fix it.

1. Add the 'deprecated' directive in the doc
2. Use subprocess for these references

What is your opinion?

Thank you,

St?phane
