[Jython-bugs] [issue2561] win32_ver raises exception

[Stefan R. <re...@bu...>]

New submission from Stefan Richthofer:

Jython 2.7.1rc1 (, Mär 3 2017, 13:27:02)
[Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.8.0_121
Type "help", "copyright", "credits" or "license" for more information.
>>> import platform
>>> platform.win32_ver()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "D:\workspace\linux\Jython\ssh\jython\dist\Lib\platform.py", line 600, in win32_ver
    import _winreg
ImportError: No module named _winreg


This is 'caused' by the fix for #2553. However win32_ver also wasn't workable before that. Only difference was that it didn't raise an exception but returned empty strings instead.
Looking at what CPython says, win32_ver would return:

Python 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:53:40) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import platform
>>> platform.win32_ver()
('10', '10.0.14393', '', u'Multiprocessor Free')

We can easily emulate the first two values. Only the build-type would be hairy to get. It's only reachable via API command, or rather invonveniently via systeminfo cmd-call (hardly possible to parse, because line-captions are localized). So I' suggest to just fill in the first two entries - better than exception or all strings empty.

In long term we might be able to improve this using JNR or by supporting the win32api extension.
