Re: dependency checker for archive needed
Hi,
I have some perl modules that look at the Packages file, parse
it into package objects, etc, written in perl 5.
The idea is to use this to create associative arrays of
available packages (/var/lib/dpkg/available), Currently installed
packages (/var/lib/dpkg/status), new packages (create a packages file
with dpkg-scanpackages or look at a Packages file n the command
line).
Then, in the checking dependency phase, for each package in
the new packages list, we look at the dependencies, and ensure that
each dependency is satisfied in either the new ist or the installed
list (I'm having problems with the greater than less than directives,
at the moment). If the directive is satisfied from the nre list, add
a line to an output file withthe format
<package-that-needs-to-be-installed-first> <current-package>
Iff all dependencies are satisfied, we run tsort on the output file,
giving us an order to install new packages in.
Unfortunately, my current implementation is very, umm,
unstable, and my new job has me travelling a lot (I'm now a
``consultant'', and have been to Hong Kong, San Francisco, and Nice
in thre last 30 days), so my time for debian is available in
bursts. (I hope to put in a burst now, but I'm scheduled to go to
Hong Kong again by the end of the month).
I'll try to polish up what I have and have it available to
people by the end of the week (I believe Fabien volunteered, right?)
I do apologize for signing up to do this and then not
producing something in a timely fashion.
