[Mageia-dev] Bug 2317.

+It's very clear from the reply in bug 2720 that some packagers still do not
+understand the scope of bug 2317.  Hence I've decided to post my reply
+to one comment here.

+
+Ever since bug 2317 was opened, qa have been watching for packages
+being installed from the Release repositories.
+
+The problem is, that the only way to recreate this problem is to start
+with a Mandriva 2010.2 system, with task-kde4 installed AND the package
+called root.
+
+When the op upgraded from Mandriva, the version specific dependencies
+of the package called root (or one of it's dependencies) prevented the
+Mandriva versions of libiodbc2 from being upgraded.
+
+Now, when an upgrade of task-kde4 is being installed using mgaapplet,
+it (or one of it's dependencies) has a version specific requires, or
+selects the package because it has a higher release, or version, for
+a package that is only in Core Release, so the update fails.
+
+This didn't happen during beta testing, as none of the people doing
+the beta testing had the package called root installed from Mandriva.
+
+I may be wrong about which package prevented the dependencies from
+being installed, but that doesn't matter.  Some Mandriva package
+(not available in Mageia 1) has version specific requires, which
+blocked the update during the upgrade to Mageia.
+
+The only possible methods of dealing with this (as I see it) ...
+- Alter MegeiaUpdate to do the equivalent of urpmi --auto-select
+- link all of the Release packages in the Release repositories
+   in corresponding Updates Testing and Updates repositories.
+   (Massive synthesis.hdlist.cz files)
+- Create installations of Mandriva 2010.2 with all possible combinations
+   of packages, and test every update on each installation.
+   (Not possible with time/diskspace)
+- For each  update, get a list of every dependency, then get a list of
+   every package that requires that dependency on Mandriva 2010.2, and
+   check each of the .spec files for version dependant requires, and
+   link those packages only, to both Updates Testing, and Updates.
+   (Very time consuming for QA).
+
+While changing MageiaUpdate to do the equivalent of urpmi --auto-select
+will have an impact on speed, it is the only reasonable solution, in
+my opinion.
+
+I tried to provide a patch to fix the problem, it failed, as it also
+picked up suggestions from non-enabled repositories. While I can usually
+figure out what perl code does, I'm not a perl programmer.  We need
+someone who knows perl and urpmi, to fix this, and quickly.
