From bnc#707731 some more thoughts: I don't think the above can be achieved using rpm dependencies in any way. Thus the only reasonable thing is to provide a link from %name-debuginfo to %name to relate them and have the solver and/or the package install frontend do the above magic manually.
And that's exactly why we need a 'Requires: %name = %version-%release'.
No, we don't. A 'Requires: %name = %version-%release' does not merely link the packages but constitutes a bogus fact that the %name-debuginfo package requires %name in any form which it does not! I can perfectly well install _only_ a debuginfo package and inspect its contents, or use it from gdb when inspecting a core file. Thus, a requires is _wrong_. You could maybe say that it conflicts with %name != %version-%release but even that would be wrong in the core file case (where I want to be able to install a specific -debuginfo package, which is even suggested by gdb(!), without eventually needing to downgrade/upgrade my systems library packages).
'zypper (d)up' and 'yast2 --install' already ask what do with the non-fulfilled dependency (see my comment in bnc#707731):
Example with https://build.opensuse.org/request/show/79821 applied: Basis: envytools-20110825.0522-1.1 and envytools-debuginfo-20110825.0522-1.1 are installed

Problem: nothing provides envytools = 20110825.0522-1.2 needed by envytools-debuginfo-20110825.0522-1.2.x86_64 Solution 1: do not install envytools-debuginfo-20110825.0522-1.2.x86_64 Solution 2: break envytools-debuginfo by ignoring some of its dependencies

The following packages are going to be upgraded: envytools envytools-debuginfo
#envytools-debugino-20110825-0522-1.2.x86_64.rpm is in the path zypper in ./envytools-20110825.0522-1.1.x86_64.rpm Loading repository data... Reading installed packages... The selected package 'envytools-20110825.0522-1.1.x86_64' from repository 'Plain RPM files cache' has lower version than the installed one. Use 'zypper install --fo rce envytools-20110825.0522-1.1.x86_64' to force installation of the package. Resolving package dependencies...
Nothing to do.

Problem: envytools-debuginfo-20110825.0522-1.2.x86_64 requires envytools = 20110825.0522-1.2, but this requirement cannot be provided Solution 1: deinstallation of envytools-debuginfo-20110825.0522-1.2.x86_64 Solution 2: do not install envytools-20110825.0522-1.1.x86_64 Solution 3: break envytools-debuginfo by ignoring some of its dependencies
So I cannot understand your worries - openSUSE's frontends can handle such things.
"handle" by asking the user. But then there is no way to make my above use-cases work with that requirement encoded in the package. So, no, I think adding a requires is a step in the completely wrong direction. Btw, see the initial description on how existing tools can link %name and %name-debuginfo (if not simply looking at the package name only). I think this -debuginfo stuff is purely a frontend issue, apart from maybe providing a more reliable link from %name-debuginfo to %name (you can add a Provides: debuginfo(pkg) = %name or similar). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
