- 1 master, 3 slaves
- stop maxscale so it does not autorejoin later on
- stop & reset slave on servers 3 & 4
- add data to server 4
- restart maxscale, check that server 3 is rejoined but not server 4
- manually set server 1 to replicate from server 4, creating a relay master
- check that servers 2 & 3 are redirected, making server 1 just a slave
- switchover master to server 1, check that it's the master
Also, moved some common functions into their own files. These functions
are used by multiple tests.
Added some code to detect server states in a consistent manner and created
the test. The multi-source replication appeared to cause problems for the
test system which needs to be resolved.
Added --force flags to most direct `mysql` calls to prevent errors from
stopping the processing of remaining commands.
The test expected the wrong error message to be in the log. To better cope
with changes in the text, the test now uses a regular expression to do the
matching.
The scripts start MaxScale processes on two different servers. The support
framework for the tests is in place but the tests themselves still need to
be modified to allow the use of non-localhost addresses.
The ssh_node function now supports printf style arguments. This is used to
simplify command execution on the nodes.
Curreltny, in addition to its old usage, it is used to drop extra
databases when replication is started.
The slave part of the binlogrouter replication can be ignored for
avrorouter tests. This will speed up the testing by skipping the
unnecessary restarting and configuration of slave servers.
