Description Mamoru TASAKA 2010-07-27 07:22:34 UTC
Description of problem:
Currently my system has:
# grep ^boost /var/log/rpmpkgs | sort

It seems F-13 boost creats -mpi{,-python} subpackages,
while rawhide boost does not.
This causes upgrade path breakage when python27 rebuilt packages
is to be imported into rawhide tree:
# env LANG=C yum --enablerepo=koji-py27 upgrade python
Error: Package: boost-mpi-python-1.41.0-4.fc13.i686 (installed)
           Requires: libpython2.6.so.1.0
           Removing: python-libs-2.6.5-17.fc14.i686 (installed)
           Updated By: python-libs-2.7-7.fc14.i686 (koji-py27)
               Not found
           Available: python-libs-2.6.4-27.fc13.i686 (koji-13)

So boost-mpi{-python} packages must be obsoleted by some rawhide
boost related packages.

The following links give the lists of sub-packages produced for Boost:
- on Rawhide/F14: http://koji.fedoraproject.org/koji/buildinfo?buildID=186705
- on Fedora 13: http://koji.fedoraproject.org/koji/buildinfo?buildID=176643

So, on both the distributions, no -mpi{,-python} sub-package is produced.

However, in an alpha version of the Boost RPM specification file (1.41.0-4, which you seem to have used), such sub-packages were produced: http://koji.fedoraproject.org/koji/buildinfo?buildID=152830
But (the final version of) Fedora 13 has shipped with Boost 1.41.0-7 (ftp://ftp.free.fr/mirrors/fedora.redhat.com/fedora/linux/releases/13/Fedora/i386/os/repoview/ for a quick view and http://download.fedoraproject.org/pub/fedora/linux/releases/13/Everything/i386/os for more details), in which no -mpi{,-python} sub-package has been produced.

So, your issue seems to come from the fact that you use(d) an early beta version of Fedora 13.

Comment 2 Mamoru TASAKA 2010-07-28 14:02:52 UTC
Well, actually I use(d)
rawhide -> rawhide ->  F-13 development branch -> rawhide (now)
( -> F-14 development branch )
Anyway I think adding Obsoletes is preferable.

This bug appears to have been reported against 'rawhide' during the Fedora 14 development cycle.
Changing version to '14'.

More information and reason for this action is here:

I am not an expert, but since the draft Boost package (with -mpi{,-python} sub-packages) never made it to a stable Fedora distribution, it means that the Obsoletes concerns only early testers of Rawhide. And since Rawhide is clearly meant to be used by "adventurous" testers, with some good knowledge on how to repair broken dependencies during upgrades, I do not see why all the users of stable Fedora distributions should inherit from that Obsoletes directive.

But I may have missed something.
