Bug#623485: python-apt: please add bindings pkgOrderList

[Pietro Abate <pietro.abate@pps.jussieu.fr>]

Package: python-apt
Version: 0.7.100.3+b1
Severity: wishlist


Hello,

This is a request to add a new binding to the class pkgOrderList of apt.
The idea is to allow to compute and set the pkgOrderList independently
and reason about it.

At the moment the only way to compute (via apt-get) the installation
plan is to execute it and print a debug trace of it. 

For the mancoosi project we would like to compute the plan before
executing it and to simulate the installation in order to detect
possible problems in the installation scripts.

I'm aware that this binding will export a read-only object and that the
installation plan will be recomputed by apt-get. This will be sufficient
for our goals.

Provided a bit of guidance (I'm not very familiar with the apt python
bindings), we'll be happy to provide a patch.

look forward for your feedback.

pietro
