The test now uses maxctrl to count how many connections there are. This
helps avoid creating new users on the database and works around the slave
syncing problems.
The blocking of the nodes that happens before it could cause the
connections to break. This also removes the need for the fixing of the
replication which takes time.
See script directory for method. The script to run in the top level
MaxScale directory is called maxscale-uncrustify.sh, which uses
another script, list-src, from the same directory (so you need to set
your PATH). The uncrustify version was 0.66.
The code that selects the candidate backend always returned the root
master if the server bitmask contained the master bit. This should only be
done if the master bit is the only bit in the bitmask and when there are
other bits, the normal candidate selection code should be used.
Also added a query to the expanded test case to make sure the connection
actually works.
The test case now verifies that the servers are actually load balanced
correctly. This test reveals a problem in the readconnroute; the master is
always preferred over slaves if one is available with
router_options=master,slave.
