Please unblock package python3-defaults
First, apologies for this late unblock request. I'd been focused on getting
python2.7/python-defaults updated and thought one of my co-maintainers had
taken care of this already. Changelog below is annotated with why I think
this should be unblocked.
python3-defaults (3.2.3-6) unstable; urgency=low
[ Piotr Ożarowski ]
* dh_python3
- ignore empty files while trying to normalize shebangs
This fixed build failures, so there are likely packages that built since this
was uploaded to Sid that won't build in Wheezy.
- mention the right file (debian/py3dist-overrides) while warning about
guessed dependency - thanks to Sebastian Ramacher for the patch
(Closes: #685067)
Trivial documentation fix. Not critical, but good to have and certainly not
worth a TPU upload to avoid.
- fix generating dependencies when maximum version is specified
(Closes: #687060)
This fixed build failures, so there are likely packages that built since this
was uploaded to Sid that won't build in Wheezy.
* py3versions.py: fix parsing DEBPYTHON3_SUPPORTED env. variable
(versions should be separated using comma, as in debian_defaults
config file)
This is similar to the change that was just part of the python-defaults
unblock. It's here for tests. There are packages that use the env variable,
but all maintained by p1otr and he'd checked they work with this change. To
stay in line with the way pyversions.py will work in Wheezy, this should go
in.
* py3versions, debpython: close previously opened files - thanks to Dmitry
Shachnev for the patch (Closes: #686587)
This is a bug. Not critical, but not worth a TPU upload to avoid.
[ Dmitry Shachnev ]
[ Barry Warsaw ]
* py3clean: Don't remove everything in the __pycache__ directory for
system site package directories. Prevents bogus cleaning of unrelated
*.pyc files. Original patch by Dmitry, with review, clean up, small
modifications, and additional comments by Barry. (Closes: #685167)
This is a significant bug that should be fixed.
[ Barry Warsaw ]
* dh_python3: Rework calculation of extension tags to add support for
Python 3.3's different suffixes, and to allow for unadorned .so files
to assume they are built with the default Python 3 version.
Closes: 672178
This is not essential for Wheezy, but will make working with python3.3 much
easier for people that want to do it. I think it's worth making the change to
make Wheezy a better platform for Python 3 development.
* README.derivatives: It is no longer necessary to edit
debian/py3versions.py since the values are taken from
debian_defaults. Also added some text on how to separate the
specification when multiple versions are supported.
* Makefile: Fix the nosetests3 command. Closes: 690259
These don't directly impact the way the package works and are nice to have.
Not worth uploading to TPU to avoid.

This has been in Sid for several months without issue. At this point the
risks of not including it (because packages have built against it) is, in my
opinion, greater than the risk of including it.
