You can see it on an example of java-1_6_0-sun-plugin.rpm, which obsoletes java-1.5.0-plugin and thus java-1_5_0-sun-plugin.rpm. So when you try to install both packages, zypper bails on conflicts (*), while rpm allows you to install without any problem (might be due to the fact the obsoleted name is not a package).

No, that's because you probably did 'rpm -i java-1_6_0-sun-plugin.rpm' while rpm only deletes obsoleted packages when upgrading (-U):

I see, but that still makes a difference, rpm allows you to install both at the same time while zypper does not. How would rpm behave in this scenario? # rpm -ivh java-1_5_0-sun-plugin-0.rpm java-1_6_0-sun-plugin-0.rpm # rpm -Uvh java-1_5_0-sun-plugin-1.rpm java-1_6_0-sun-plugin-1.rpm Would it complain (in the second step, the first step succeeds), uninstall 1_5_0 silently or upgrade both?

The change concerns 'virtual' obsoletes. Our rpm command only matches 'obsoletes' to package _names_. Zypp does a generic capability match which triggers also for package _provides_.

IIRC, thats a known deficiency.

zypper with the libredcarpet solver behaves similar to the 'original' rpm command. The rpm package shipped with openSUSE is modified.

But please ask Michael Schroeder for the glory details ;-)

Depends on the rpm version. rpm3 did not look at provides, unmodified rpm4 looked at provides. We patched that feature *out* in some of our releases. Currently, rpm4 *upstream* (maintained by Panu) does no longer look at the provides, while rpm5 upstream does. Confused enough?

With "provides", do you also mean "obsoletes"?

I meant that if a package contains an obsoletes, rpm will also obsolete all packages that provide this dependency.

As we are not going for rpm5 any time soon, looks like we stick with the same behavior as always.

The question is then if we should not change zypp to mimic the rpm behavior.

Oh, we already do that. I had to patch rpm in both directions to make it compatible to zypp. Sigh, Michael. -- Michael Schroeder mls@suse.de SUSE LINUX Products GmbH, GF Markus Rex, HRB 16746 AG Nuernberg main(_){while(_=~getchar())putchar(~_-1/(~(_|32)/13*2-11)*13);} -- To unsubscribe, e-mail: opensuse-softwaremgmt+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-softwaremgmt+help@opensuse.org

At least in 10.3 the behavior is different, if you try to install java-1_5_0-sun-plugin and java-1_6_0-sun-plugin at the same time, with rpm it succeeds, with zypper it fails.

True, but they obsolete each other. So if you first install java-1_5_0-sun-plugin and then java-1_6_0-sun-plugin, java-1_5_0-sun-plugin will be silently gone. I prefer zypp's error message.
