= Proposed Self Contained Change: RPM MPI Requires Provides = https://fedoraproject.org/wiki/Changes/RpmMPIReqProv Change owner(s): Sandro Mani <manisandro at gmail dot com> Have the rpm-build find-provides and find-requires scripts encode the MPI compiler name in the provides string of a binary to distinguish otherwise identical provides between packages $foo, $foo-openmpi and $foo-mpich. == Detailed Description == Currently, the packages libfoo, libfoo-openmpi and libfoo-mpich providing the library libfoo.so all have a provides string of i.e. libfoo.so()(64bit) While yum used a shortest-package-name rule to choose which package to pick, dnf does not have any rules, and seems to just pick the first match it comes across. Currently the only solution would be to filter the provides from the -openmpi, -mpich packages and add explicit Requires: where needed. I'd like to propose to extend the provides string in such way that it also encodes the MPI implementation, i.e.: $ rpm -qp --provides libfoo libfoo.so()(64bit) $ rpm -qp --provides libfoo-mpich libfoo.so()(64bit)(mpich-x86_64) $ rpm -qp --provides libfoo-openmpi libfoo.so()(64bit)(openmpi-x86_64) To this end, I'm proposing to adapt the find-requires and find-provides scripts as (or similarly to): find-provides find-requires Discussion of these changes are tracked in bug #1232504. This change is intended to coordinate the rebuild of all MPI related packages to ensure all such packages consistently use the new provides format. == Scope == * Proposal owners: - Work on find-provides and find-requires based on feedback. - As soon as updated find-provides and find-requires shipped with rpm-build, do a mass-rebuild of all MPI packages. * Other developers: N/A (not a System Wide Change) * Release engineering: N/A (not a System Wide Change) * Policies and guidelines: N/A (not a System Wide Change) * Trademark approval: N/A (not needed for this Change) -- Jan Kuřík _______________________________________________ devel-announce mailing list devel-announce@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel-announce -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
