Having helper methods that combine the index position search and value
extraction make it easier to deal with results that have a lot of fields
e.g. the output of SHOW SLAVE STATUS.
The type mask of CREATE, ALTER, etc. that cause an implicit commit
will no longer contain the bit QUERY_TYPE_COMMIT.
As an implicit commit does not change the transaction state as seen
by MaxScale, it does not make sense to claim that the statement is
a commit.
If the DCB was closed before the handshake for the LocalCliet connection
was received, the gw_decode_mysql_server_handshake would use the closed
DCB to log the connection ID. Clearing out the pointer prevents it.
The DCB callbacks shouldn't be used to send more events as they cause the
callback to be called recursively. The recursive calls caused rows to be
sent before the schemas for the rows were sent. Queuing the events via the
worker mechanism prevents this.
Reduced the default cache size from 40% to 15%. Most cases don't benefit
from that much memory and the defaults have caused problems in live
environments.
If a query spans more than a single packet, it will never be successfully
classified due to the fact that the complete SQL is never available to the
query classifier. For this reason, it is pointless to cache them.
Took the Replicator into use in avrorouter as an alternative to the
binlogrouter based setup. This also allows the avrorouter to automatically
handle master failovers and to start replication from GTID coordinates.
Repurposed the Replicator from the CDC integration project as a
replication event processing service. It is similar to the CDC version of
the Replicator and is still in the same namespace but it lacks all of the
cross-thread communication that was a part of the integration project.
If a monitor was created with an argument that was not a key-value type, a
promise would be rejected outside of the main maxctrl function. Added a
test case that covers this and fixed a few other test coverage problems
that were present.
The STL regex implementations have proven to be unreliable on older
systems and replacing the regex with hand-written code for version
extraction is less prone to break.
The test seems to fail from time to time due to the monitor not picking up
the master state fast enough. To prevent this, the test needs to wait for
at least one monitor interval.
If 'dynamic_node_detection' has been set to false, then the
Clustrix monitor will not dynamically figure out what nodes are
available, but instead use the bootstrap nodes as such.
With 'dynamic_node_detection' being false, the Clustrix monitor
will do no cluster checks, but simply ping the health port of
each server.
'dynamic_node_detection' specifies whether the Clustrix monitor
should dynamically figure out what nodes there are, or just rely
upon static information.
'health_check_port' specifies the port to be used when perforing
the health check ping.
Added core functionality for UNIX domain sockets in servers. Currently the
address parameter accepts them both but a separate `socket` parameter is
needed.
