Ubuntu 10.10 mod_wsgi package oddness.

Do you want to continue [Y/n]?
Why is it wanting to drag down Python 3.1?
Has someone screwed up package in repository or have they done stupid
thing of not naming Python 3.1 variant of package differently.
The person on #python confident they are pointing at non standard repositories.

I thought that Python 3 was a separate package:
* Move Python 3.X extension to new libapache2-mod-wsgi-py3 binary package
or does it still drag it down and install it?

Bernd, Piotr, what is the current situation?

Shared Python runtime library (version 2.6)
Now, I didn't use the dependency to pull in python. I had python
installed before I asked for mod_wsgi and it seems to be working out
all right with my 2.6 install.
I spun up a fresh vm with a brand new 10.10 64 bit install, when I
install mod_wsgi it is indeed pulling in python3.1.
Python2.6 is already installed. This is not how it worked on the
debian box, so this is most certainly a canonical bug.
The depends line from apt-cache show on the package name indicated it
should be requiring a min version of 2.6.
The way the debian/rules file is written if you do an apt-build on the
package doesn't have obvious (to me) errors.
It looks like ubuntu is tracking the debian package, and this issue
may exist in sid. I can confirm that this is indeed happening and you
may want to get in touch ubuntu-dev...@lists.ubuntu.com

[¹] http://packages.ubuntu.com/maverick/amd64/libapache2-mod-wsgi/filelist
[²] http://packages.ubuntu.com/maverick/libapache2-mod-wsgi
In Debian Squeeze³ we decided to keep Python 2.X and Python 3.X as
separate runtime systems and thus for public modules we have python-foo
and python3-foo binary packages.
That's why I added libapache2-mod-wsgi-py3 package in 3.3-1 (which
conflicts with libapache2-mod-wsgi so you cannot install both at the
same time).
[³] first Debian stable version that supports Python 3, will be released
in less than 2 weeks, BTW
mod-wsgi was synced from unstable in an unfortunate time and that's why
this problem is affecting Ubuntu only

What is the result then?
Is it safe to install on Ubuntu, with the caveat that it also drags
down Python 3.1.
In the package it has:
/usr/lib/apache2/modules/mod_wsgi.so
/usr/lib/apache2/modules/mod_wsgi.so-2.6
/usr/lib/apache2/modules/mod_wsgi.so-3.1
Is the mod_wsgi.so a symlink to one or the other, or something else,
like version for Python 2.5?

/usr/lib/apache2/modules/mod_wsgi.so is a symlink to mod_wsgi.so-2.6,
if someone (insane ;) will change default Python version in Maverick to 3.1,
a hook will change the symlink to point to mod_wsgi.so-3.1 as well
What you can do with it?
* ask Ubuntu guys to upgrade the package, or
* drop 3.1 support in 3.2-2 (by removing line 12 from debian/rules file), or
* accept the fact that python3.1 installation wasted few MiB on your hard drive
(it doesn't harm mod_wsgi as long as you have Python 2.6 set as default)

Okay, great to know. Thanks.
