/**
 * @file bug547.cpp regression case for bug 547 and bug 594 ( "get_dcb fails if slaves are not available" and "Maxscale fails to start without anything in the logs if there is no slave available" )
 * Behaviour has been changed and this test check only for crash
 * - block all slaves
 * - try some queries (create table, do INSERT using RWSplit router)
 * - check there is no crash
 */

/*

get_dcb function returns the backend descriptor for router. Some merge has broken the logic and in case of non-existent slave the router simply fails to find a backend server although master would be available.
Comment 1 Vilho Raatikka 2014-09-16 09:40:14 UTC
get_dcb now searches master if slaves are not available.

// also relates to bug594
// all slaves in MaxScale config have wrong IP
