This allows the same verbose information to be logged in the cases where
it is of use. Mostly this information can be used to figure out why a
certain session was closed.
By doing the reconnection only when a new query arrives, we prevent the
excessive reconnecting that is done when a server's actual and monitored
states are in conflict.
Galeramon will now only use the larger cluster in case a split brain
situation occurs. If the clusters are of equal size, the one whose UUID
compares less will be used. This will guarantee that all MaxScales that
see the same picture will end up using the same cluster.
With this change, a parenthesized top-level SELECT, such as
"(SELECT f FROM t)" will be fully parsed. Before this change,
the statement was classified as invalid and would thus have
been sent to the master.
With this change also statements like
(SELECT f FROM t1) UNION (SELECT f FROM t2)
will be correctly classified, although only partially parsed.
With these changes
SET @saved_cs_client= @@character_set_client;
will be classified as QUERY_TYPE_USERVAR_WRITE and
SELECT 1 AS c1 FROM t1 ORDER BY ( SELECT 1 AS c2 FROM
t1 GROUP BY GREATEST(LAST_INSERT_ID(), t1.a) ORDER BY
GREATEST(LAST_INSERT_ID(), t1.a) LIMIT 1);
will be classified as QUERY_TYPE_READ|QUERY_TYPE_MASTER_READ
The TLS parameters were defined but the main parameter that enables it
wasn't automatically added. As the REST API documentation states that this
parameter does not need to be defined, the runtime configuration must add
it.
When a system test program is invoked with the flag '-l', it will
assume MaxScale is running on 127.0.0.1 using a configuration that
is compatible with the test.
NOTE: Currently any test that directly or indirectly sshes to the
MaxScale node will fail. With a bit of setup that could also
be made to work.
In some configs /etc/my.cnf.d/* files access rights are
very limited and server can not read configuration.
It leads to broken settings and unability to setup
replication during the test
Because of how the user-data was read, the same service name could be
found multiple times if the user-search query matched multiple rows. Now
the service names are read to a set, which ignores duplicates. The same
service may be attempted again if the authentication fails and user-data
is fetched again.
Authenticators and monitors now use SSL when configured. The fix has two parts:
1) Removed the extra SSLConfig inside SSLProvider, as SSLContext already contains
the config.
2) When inputting parameter values to mysql_ssl_set(), empty strings are converted
to NULL-pointers as the function expects those for unused values.
