- 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.
* refactor test backend fixing
* return comatibility with 5.5 for backend restore
* remove backend configuration scripts
* adopt test backed restore function for 2.2 test fw
Combined functions into one which only used different default
values. Removed unused functions. Used std::string where possible to make
their usage easier. Hid code that isn't used externally.
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 MaxCtrl test suite is now a part of the regression test suite. The
cluster tests are expected to fail as that is yet to be implemented.
Also fixed the return value of TestConnections::ssh_maxscale.
The tests now print a stack trace to standard output if it receives a
fatal signal. This will help debug test failures caused by broken tests
and unexpected results.
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.
Every time MaxScale was restarted, the test waited for a total of 25
seconds. As MaxScale should start before the command returns, the sleep is
not necessary.
Added StartLimitBurst=0 to the systemd service file to allow rapid
restarts of MaxScale.
The replication needs to be stopped before the binlogrouter is started. If
the replication is stopped after this, it is possible that two servers
with the same value of server_id attempt to register as slaves which
causes the later of them to fail.

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.
