Summary: rpm Obsoletes does not handle virtual dependencies Product: openSUSE 10.2 Version: Alpha 4 plus Platform: Other OS/Version: Other Status: NEW Severity: Major Priority: P5 - None Component: Basesystem AssignedTo: mls@novell.com ReportedBy: rguenther@novell.com QAContact: qa@suse.de CC: aj@novell.com

rpm currently does not allow updating with -Uhv that would require removal of another package providing the same virtual provides.

Consider:

libgcc41 Provides: libgcc = 4.1.0 Obsoletes: libgcc < 4.1.0

libgcc42 Provides: libgcc = 4.2.0 Obsoletes: libgcc < 4.2.0

if now libgcc41 is installed and we want to install libgcc42, rpm does not know it needs to deinstall libgcc41, even though libgcc42 obsoletes libgcc.

If we know beforehand that libgcc41 exists at the time of packaging libgcc42 this can be worked around by obsoleting libgcc41 as well in libgcc42.

But now let's introduce a libgcc33 package which libgcc42 does not know about and things break again.

libgcc33: Provides: libgcc = 3.3.3 Obsoletes: libgcc < 3.3.3

Somehow teaching rpm to do the right thing here (deinstall all providers of libgcc < $VERSION if libgcc < $VERSION is obsoleted by a to-be-installed package) is essential.
