[Patch] Re: [Yum-devel] YumInstalledPackage

[Jack Neely]

Paul,

Attached is the code I was playing with.  I'm working with code for
kernel module handling which compares specific Requires of kernel module
packages.  (Do they require the same kernel?)  The method that you and I
mucked with a bit doesn't quite cut it.  The meta data that gets
populated into YumAvailablePackage looks like:

    (name, type, (epoch, version, release))

where type is 'EQ', "LT', etc.  Getting that info out of RPM gives me

    (name, code, "e:v-r")

I don't want to parse that.  I don't want to duplicate the code that
does it in createrepo.  In this case its not too hard to parse, but
*sigh*.

Jack
