anaconda dependency calculation?

Hi all,

I'm trying to find a tool that calculates all dependencies
for a 
specific package or group of packages for use with CentOS 5
(beta) with 
the intention of putting together a custom single CD build
of CentOS 5. 
With CentOS 4 i used a python script that used the hdrlist
module to 
find all dependencies which borrowed code from a number of
sources.

I've looked at yumdownloader and how it checks dependencies
(using the 
--resolve option) but if i pass it the list of packages
defined in say 
the Base and the Core yum groups which generally form an
absolute 
minimal install i end up with about 200 packages. If i do a
custom 
install (using beta 1 disks) and deselect everything i end
up with over 
300 packages.

So i'm guessing anaconda calculates dependencies in a
slightly different 
way, can anyone point me to files/code where i should be
looking to find 
out?

Thanks very much in advance for help
Nick

Easiest solution is likely to just generate a hdlist (using 

genhdlist) and do what you did before.

There's a copy of genhdlist in rpm sources if you need.

Thanks Jeff i'll do that, should have thought of that myself
really. Out 
of interest (if you know) is there a "proper" way
though (even if it's 
not released/stable etc)?

AFAIK, the replacement is rpm-metadata xml instead of hdlist
headers.

hdlist headers are dirt simple compared to the tools
necessary to
parse xml.

FYI, rpm-4.4.3 and later has a -H,--hdlist command to query
hdlist's

E.g.
	rpm -qa -H
displays all the headers in a hdlist.

There's also a -T to display the order in which rpm would
install, as
     rpm -q -HT

Some of that functionality might be useful no matter what
rpm you have
chosen to install and use.

Is installing off a webserver and inspecting the logs too
difficult? It 
would tell you all the files used for that selection, and
the order 
which you could then use to optimise file ordering on the
ISO image.

Still? I thought genhdlist had been retired, not required in
Anaconda 
using yum.

The guy had tools to deal with hdlist headers, nothing
more.

The copy of genhdlist.c is within rpm sources for reference
purposes.

genhdlist has never been anything but a sick'n'quick
encapsulation of  
package metadata.

R.I.P. Ptooey!

The last version of RPM2 on cpan had a mechanism for reading
hd lists
(don't think it made it in the docs though), and I believe
the python
rpm bindings have this too.

I've just started looking at yumdownloader to perform that
task. I've 
found a --installroot patch for it, so that (hopefully and
apparently) it 
will not use the build system's rpmdb and will start with a
clean slate. 
It runs to completion, and does *some* dependency
resolution, but it's 
clearly deficient. There are *lots* of unsatisfied
dependencies in the 
resultant package set.

I think this is an issue to take to the yum-devel list. I'll
try bleeding 
edge yum/yum-utils and see if it does a better job.

Thanks for the info, i'll keep eye on that list to see what
you 
discover. I used genhdlist as per v4.x which worked fine
with a few 
tweaks. I've now got a pretty solid respin.

However i came across the redhat buildsys list 
(https://www.redhat.com/archives/fedora-buildsys-list/) 
which i didn't 
know about until recently and then discovered Pungi on it 
(https
://hosted.fedoraproject.org/projects/pungi) for Fedora
which looks 
very promising.

I'm going to have a go at getting it to work for CentOS 5 at
some point, 
as really there shouldn't be too much in the way of
differences and it 
purports to do full dependency resolution.

Cheers
Nick
