[issue26095] Update porting HOWTO to special-case Python 2 code, not Python 3

2016-01-12 Thread Nick Coghlan 

Nick Coghlan added the comment:

The feature detection approach is especially important for anything covered by 
the security backports in PEP 466 and 476, but can also apply for things like 
installing the importlib2 meta_path hooks into Python 2.7.

And suggesting feature detection is even better than version detection.

[issue26095] Update porting HOWTO to special-case Python 2 code, not Python 3

2016-01-12 Thread Brett Cannon 

New submission from Brett Cannon:

As pointed out by 
http://astrofrog.github.io/blog/2016/01/12/stop-writing-python-4-incompatible-code/,
 special-casing Python 3 code instead of Python 2 code when writing Python 2/3 
code will lead to breakage when Python 3 comes out. There should probably be a 
note in the porting HOWTO mentioning that you should always special-case Python 
2 code and not Python 3 code.
