A journey to python 3: porting redis-limpyd

Introduction

A few weeks ago, I - Twidi - made a proposal to talk about redis-limpyd at Pytong.

And it was accepted. But... the main subject of Pytong is "After python 2".

redis-limpyd currently only works on python 2.6 and 2.7, and as I said during my lightning talk at PyconFR in October 2013 (start at 47:50), "porting to python 3 is on it's way"... but the only thing that was done at this time - and it's still the case as I'm writing these lines - was a simple run of the 2to3 command to see the things that needed to be done, by Yohan Boniface, original author of the project.

# Ce que je voudrais
SELECT AVG(last_updated_at - created_at) FROM monapp_item;
 
# Ceci fonctione
Item.objects.extra(select={'delta': 'last_update_at - created_at'})
 
# Mais pas ça
Item.objects.extra(select={'delta': 'last_update_at - created_at'}).aggregate(Avg('delta'))

- we use `ack` (`ack-grep`)
- we assume builtins are marked so, or in a `python*` directory in a `lib` one, but not in `*packages*` (`site-packages for example`)
- everything that cannot be imported is not a builtin package

If your python is not in a "lib/pythonX.Y" directory, you can change the path.

PS: on my machine, it works in a virtualenv
