Here: http://ep09.pld-linux.org/~mmazur/pld-rpm/ver1.patch is the first version of a patch I'm making. It has one purpose - to allow automatic upgrade to a new version of any given distro. It does so by introducing a new field in rpm headers called distversion. The general idea is quite simple - if a system has package A installed and it's distribution field is eg. 'PLD', and we're trying to upgrade to package B which also has distribution field set to 'PLD', *and* our current distribution is in fact PLD, than rpm checks wether distversion fields are present in both packages. If so, than the package with higher distversion (as compared by rpmvercmp()) always takes precedence even if EVR of package A is less than or equal to EVR of installed package B. This functionality is meant only to ease upgrades - distversion field is by no means taken into account in Rs, BRs, etc. By default it's only taken into account if a package we're trying to upgrade to (and the already installed one) is in fact meant for the distribution we are currently using - in any other case rpm behaves as usual. Some defines can modify this behavior, but that's in the patch for now, I'll document it when I'm finished. Two things are still missing - many distros use the Distributions field in rpms not only for the distro name, but also for it's version (eg. 'PLD 1.0 Ra') which means I'll have to add some flexible translation mechanism that will allow distribution vendors to explicitly state that 'Fedora Core 1' or sth is just 'Fedora' as far as distversion comparison algorithm is concerned. The second thing is support for apt-get like tools to also be able to take distversion field into account (I'll be using poldek as a reference, so don't count on that functionality to be complete). Currently only command line install/upgrade is supported (and works :). Example: # rpm -q fix-info-dir fix-info-dir-0.13-6 # rpm -q --queryformat '%{distribution}-%{distversion}\n' fix-info-dir PLD-2.1 # rpm -qp --queryformat '%{distribution}-%{distversion}\n' fix-info-dir-0.13-5.i686.rpm PLD-2.2 # rpm -U fix-info-dir-0.13-5.i686.rpm # rpm -q fix-info-dir fix-info-dir-0.13-5 # rpm -U fix-info-dir-0.13-6.i686.rpm package fix-info-dir-0.13-6 is for older distribution than already installed fix-info-dir-0.13-5 # The patch in it's current form is not mergeable, but that should change when it's completed. -- In the year eighty five ten God is gonna shake his mighty head He'll either say, "I'm pleased where man has been" Or tear it down, and start again _______________________________________________ Rpm-list mailing list Rpm-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/rpm-list
