Using commas instead of spaces prevents a the misinterpretation of
commands as hostnames. If the `--hosts` option was given just before a
command, it would consume the commands as arguments to the `--hosts` list.
Only asynchronous authenticators require the thread-specific loading of
users as the synchronous ones all share the same data. If the service does
not declare asynchronous capabilities at startup, the users are not
seeded. This prevents unnecessary loading of users at startup.
If node00 is not the master when a test is started, the cleanup
performed by TestConnections takes considerable time.
By restoring the sitation back to normal before ending the test,
the startup time of the next test can be shortened significantly.
Time elapsed is now properly tracked during a switchover. After slave
redirection, an event is added to the master. Then, the slaves are queried
repeatedly until they advance to the newest event. I/O and SQL errors are
also detected.
Setting the query classifier with an absolute path makes it easier to
manage test setup without having to manually resolve the relative path to
the query classifier from the test source directory.
When an assertion fails due to an overflow of the event buffer, all
processed values for that event are dumped.
This commit also enables the assertions even for non-debug builds which
should speed up the elimination process for bugs in the avrorouter. The
overhead of doing this is minimal as the output is already gathered for
the INFO level logging.
The query classifier was not initialized for the housekeeper thread. This
means that tasks could not use the query classifier and as the avro
conversion is done inside a task, it can't use it.
Now that mariadbmon supports failover and switchover, a test may
may change the master to some other node than node 0.
Consequently, as part of fixing the replication, gtid_slave_pos
of node 0 must be reset as well.
As the stale status is not a real status bit and it's used to retain the
history of a master, there is no need to print it in any output. This
output will only confuse users now that the stale status will not be
cleared from masters that go down.
The test uses standard setup (1xMaster, 3xSlaves).
1. Shutdown master (server 1), check that autofailover promotes
a new master.
2. Stop MaxScale.
3. Start server 1 and add some events to it so it can no longer rejoin
cluster.
4. Start MaxScale, check that server 1 does not join.
5. Set current master to replicate from server 1, turning it to a relay
master.
6. Check that server 1 is master, all others are slaves (due to auto-rejoin).
