Package: python-support Version: 0.6.3 Severity: important While working on thuban I used this control file: http://svn.debian.org/wsvn/pkg-grass/packages/thuban/trunk/debian/control?op=filerev=0sc=0 introducing the alternative field Python-Depends: python-wxgtk2.6 (= 2.6.3), python-sqlite (= 0.4), python-xmlbase The resulting Depends field is: Depends: libc6 (= 2.3.6-6), libgcc1 (= 1:4.1.1-12), libgdal1-1.4.0, libstdc++6 (= 4.1.1-12), libwxbase2.6-0 (= 2.6.3.2.1.5), libwxgtk2.6-0 (= 2.6.3.2.1.5), proj (= 4.4.1-1), python2.5-xmlbase, python2.5-wxgtk2.6, python2.5-sqlite, python-xmlbase, python-sqlite (= 0.4), python2.4-wxgtk2.6, python-support (= 0.2), python2.4-xmlbase, python-wxgtk2.6 (=2.6.3), python (= 2.4), python2.4-sqlite, gdal-bin (= 1.3.2-1) Note that it depends on ALL alternative versions for 2.4 and 2.5 - which are the pyversions I declared (2.4-). It should depend in OR from those alternatives, not requiring the installation of all damn per-python version modules AFAIK. For instance in this case: python2.5-wxgtk2.6 | python-wxgtk2.6 python2.5-xmlbase | python-xmlbase python2.5-sqlite | python-sqlite So currently the Python-Provides field is simply unusable IMHO. -- System Information: Debian Release: 4.0 APT prefers unstable APT policy: (990, 'unstable'), (500, 'testing'), (1, 'experimental') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.18-3-686 Locale: [EMAIL PROTECTED], [EMAIL PROTECTED] (charmap=ISO-8859-15) Versions of packages python-support depends on: ii python2.4.4-2An interactive high-level object-o python-support recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

While working on thuban I used this control file:

introducing the alternative field
Python-Depends: python-wxgtk2.6 (= 2.6.3), python-sqlite (= 0.4),

which are the pyversions I declared (2.4-).
It should depend in OR from those alternatives, not requiring the
installation of all damn per-python version modules AFAIK.
This is expected. The per-python version are virtual packages which have
to be provided by the packages you depend upon. This doesn't mean, in
your example, that python2.4 and python2.5 will be brought, only that
python-wxgtk2.6 and so on have to provide the python2.5 interfaces.
If you don't do that, the Provides: field is meaningless. This was
discussed at large in Oaxtepec. Note that you don't need to use
Python-Depends if you don't have a Provides: ${python:Provides}, but
it is recommended.
For instance in this case:
python2.5-wxgtk2.6 | python-wxgtk2.6
python2.5-xmlbase | python-xmlbase
python2.5-sqlite | python-sqlite
These dependencies would be semantically wrong.

Sigh, I understand it is expected, but I find it ugly. If someone would
use just one single python version has to install tons of packages for
all other versions too. In the specific case I have to install also both
2.4 and 2.5 editions for every modules the program use. I know it does
not require installation of all python interpreters too, but it does not
make me feel better :)

So I have definitively to use Python-Depends even if the program
deos not provide public modules/extensions? Is that documented?
For instance in this case:
python2.5-wxgtk2.6 | python-wxgtk2.6
python2.5-xmlbase | python-xmlbase
python2.5-sqlite | python-sqlite
