Re: Python 2.7 for Squeeze?

Of course most other upstreams that want their code to run on an
existing server install, with minimal hassle, support Python 2.6 or even
2.5. The enterprise distributions move *very* slowly. I know of people
complaining that their deployment environment only has 2.4...

That would be required to fix some bugs (wheezy doesn't even have 2.7 as
default yet, but that'll happen in the next week or so).
Many packages will support 2.7, but some of them will need to be rebuilt
to support it (i.e. C extensions, or packages using dh_python2)
I suspect that such rebuilding probably couldn't happen in Debian's
backports, as it would impact many packages.

You actually need someone on the backports team.

python-defaults is a source package. It builds the "python" package,
"python-all", etc. This determines what verions of python are available
and supported.
If you were to add 2.7 as a supported version, you'd have to touch
python-support and python-central as well. They hardcode supported
python versions. And before you could do that, you'd need to ensure that
every pure-python module is 2.7-compatible or has XS-Python-Version: <<
2.7 (or equivalent) in the source package.
Or you'd run into bugs like these:

virtualenv uses python-support, so to get it to work under 2.7, you'd
have to change python-support, which means everything else using
python-support would have to be 2.7 compatible.
Maybe I'm being overly pessimistic, but this sounds like an impossibly
big task for doing properly in debian-backports.
