Re: Another little bug in pkg-order
Hi,
The only dependency checks made by the library are the ones
explicitly requested; so I think in this case that is the set of
packages to be installed.
I think maybe you should look at creating the dependencies and
checking them for the installed packages as well (give the same list
twice as arguments). I hope this won't make things too slow. Maybe
keep tags of whether the installed or the new list is changed, and
recheck as needed?
In the Deity code I'm starting to work on We are considering
ordering all interactions with dpkg; that means purges and removes as
well. For the most part we put the removes first in the list (even if
it fails, the package is marked for removal; and shall be removed
when the conflicting package is tried to be installed).
The problem I see is if there is an old package A, superceded
by a new package B, and a new package C conflicts with A and not
B. In this case, B should be installed ahaead of C, but there is no
explicit relationship between B and C. Hmmm. This requires thought.
