While working on #12326, it's realized that many modules and applications rely
on sys.platform. Change this value should be decided for each platform because
it breaks backward compatibility. Linux was a special case and now I

Having the major version in sys.platform only for a few selected platforms
doesn't seem too consistent for me.
If linux 4 will introduce major changes, will we have to look for the major
version of freebsd in sys.platform and for the

If we're changing linux2 / linux3 to just linux, we should be
consistent and do it for everybody. I propose sys.platform under 3.3
should contain things like linux, freebsd,

these OSes.

sys.platform refers to build time information,
so the platform module won't help.
When I wrote my patch, I realized that sys.platform is used to get the runtime
information, which is wrong. See the tests in Lib/test/test_*.py:

It is mostly to test FreeBSD major version, and it looks like Python is

But in general you are right: if you use system provided Python
packages, chances are that your runtime OS version will be
identical or very close to the build time OS version.

New submission from STINNER Victor victor.stin...@haypocalc.com:
sys.platform contains the major system version. If you test the sys.platform
value (e.g. sys.platform == 'linux2'), your program doesn't work anymore with
the new system major version (e.g. Linux 3). This problem is common with

there is the diffstat :

I think this change should be much much smaller in scope. It was (nearly)
agreed to drop the major version if the system is Linux. There is no consensus
(that I'm aware of) to drop the major OS version for all systems.
So I would propose

At the beginning, I thaught that it would be better to remove the major version
from sys.platform on all platforms. When I started to write the patch, I
expected to change only 2 or 3 files. But the patch is now huge (26 files
