I am curious as to whether the django community cannot comfortably do
away with support for python 2.3 in the effort towards django 1.0.
There were significant changes made between python 2.3 and 2.4, and
continuing support of 2.3 in the django code base is a significant
restriction. As django 1.0 will not be fully compatible with .96,
this might be an opportune time to drop the 2.3 support.
The peps of most import to my reasoning for dropping 2.3 support in
1.0:
PEP 218: Built-In Set Objects
Allow the removal of code that conditionally loads the set module
and allow the use of frozenset
PEP 289: Generator Expressions
Efficiency in a web server is very important. There are many
instances in the code base where list
comprehensions are used when generator expressions would more than
suffice. As a list comprehension
basically wraps a generator expression in a call to list(), many
unneeded temporary lists can be avoided.
The resulting saving in cpu and memory could be significant.
PEP 318: Decorators for Functions and Methods
It is a shame that the code base can't take advantage of decorator
syntax, even as it defines useful decorators.
PEP 322: Reverse Iteration
another opportunity to reduce code
PEP 327: Decimal Data Type
I have seen much discussion in the group about the inclusion of
decimal.py in django.contrib.util
Removing 2.3 support makes that entire line of discussion moot.
The other peps from new in 2.4 ():
PEP 331: Locale-Independent Float/String Conversions
PEP 237: Unifying Long Integers and Integers
PEP 292: Simpler String Substitutions
PEP 324: New subprocess Module
PEP 328: Multi-line Imports
So, the question is "Does django 1.0 need to continue support for
python 2.3?"
Or, even more agressively, remove support for 2.4, as well?
Thoughts?
