Agreed. Can you elaborate on what "experimental support for Python3 as the
Python that is shipped on the various Ubuntu ISOs" means to you? Does that
mean no Python 2.7 on the ISO? Also, by "experimental" do you mean having
a process for creating alternative CDs that have only Python 3.2 but not
on the standard daily CDs?
There is a lot of Python code in the Ubuntu insfrastructure. I'm not sure
exactly what I meant by that, but here's an example:
Ubiquity is written in Python. It's a reasonably complex program that is non-
trivial to maintain and improve. It's also mission critical for Ubuntu. I
would be really suprised if it was fully ported with no regressions in one
cycle. In this case, I think "experimental support" would be a python3 branch
that ~works, but may not be fully tested/have issues/or not be at feature
parity so we wouldn't want to switch to it in the oneiric cycle.
The goal would be to have it be mature enough during oneiric that in the "P"
cycle we could switch to it early and have it land ~smoothly for the LTS.
I know there are others.
My impression is that most upstreams for core desktop packages support
Python3. Mostly what we lack is packaging changes to support it. My
expectation is that most of the challenge around a Python3 desktop in "P" will
be around more peripheral modules/extensions and custom Ubuntu code.
That shouldn't preclude shipping some Python3 stuff in oneiric if it's ready
and we've got room on the relevant image.
Does that help?
It does, thanks. I wonder, with work going on in Launchpad to support
derivatives, can we pervert that to create a Python 3 Ubuntu derivative that
could be used for this experiment? It may not be fully functional, but I
think it would be a great test and status tracker for how well our Python 3
efforts are going.
which packages are affected, and what work is needed to get these packages even
built?
