PKG Library naming incompatibility between Percona-Server and Percona-XtraDB-Cluster RPMs

[James Brown]

On CentOS, regular (non-Cluster) Percona 5.7 includes the package Percona-Server-shared-57, which provides libmysqlclient.so.20. Percona Cluster 5.7 includes the package Percona-XtraDB-Cluster-shared-57, which provides libperconaclient.so.20. Note that Percona Cluster 5.6 provided libmysqlclient.so.18, so this is also an upgrade hazard which is not mentioned in the Upgrading section of the manual.

These packages are marked as conflicting with one another, but provide non-overlapping shared libraries.

This seems to make it impossible to move from non-cluster Percona Server to cluster Percona Server without either doing something incredibly obnoxious like symlinking all of the shared libraries, or re-linking any software on the system which links against libmysqlclient.

My strong preference would be that Percona-XtraDB-Cluster provide libmysqlclient instead of providing libperconaclient.

This incompatibility is present in the latest available packages, Percona-Server-shared-57-5.7.17-11.1.el6.x86_64.rpm and Percona-XtraDB-Cluster-shared-57-5.7.16-27.19.1.el6.x86_64.rpm. It seems to have been present in all Percona-XtraDB-Cluster versions going back to at least 5.7.12.

This is similar to #1580764, but somewhat more critical since it affects what should be a safe operation of moving from Percona-Server to Percona-XtraDB-Cluster.

I have literally no idea why this package is marked as Conflicts with `Percona-Server-shared`.

Upstream made changes to the RPM scripts/configuration in 5.7.14 to facilitate the install of multiple client library versions. Please include the changes in your release of 5.7.14.
