Using oqgraph/connect engines in mariadb-galera-server


Hi Serg, Svoj!

I am looking into an issue where accessing oqgraph/connect engines from
galera server
leads to errors like "Unknown option '<table option>'" and segfaults. The
issue being the
differences in handlerton structure in galera and non-galera server codes.

Since the connect/oqgraph packages are built from non-galera server, when
they are
loaded into galera server, the engine's handlerton gets improperly


I can think of the following potential solutions :

a) Club connect/oqgraph and mariadb-galera-server into a single package.
(this would
    mean adding new dependencies to mariadb-galera-server)
b) New packages for connect/oqgraph out of mariadb-galera build
    (mariadb-connect-engine-galera-10.0, mariadb-oqgraph-engine-galera-10.0)

Do you see any other option? Also, we should add some checks for plugin load
to fail in first place in such scenarios.
