New service parameter ‘localhost_match_any’ allows localhost matching
the wildcard host.
Default value is 0, don’t match.
It may be changed if backend servers don’t have the anonymous user
‘’@localhost
server/core/config.c: Removed unused if..else block from config_get_valint. Changed it also to return value which indicates whether the operation succeed. Added config_get_valbool similar to config_get_valint.
service.c:Added typelib-like struct and array of valid boolean values. Fixed parameter type test in service_set_param_value. Completed boolean type parameter handling.
hintparser.c:Fixed error message for non-maxscale hints.
readwritesplit.c:Added loading of configuration parameters from service to instance and from instance to each new session. Fixed routing condition in get_route_target. Modified get_route_target so that it takes also rw_read_sesvars_from_slaves and rw_write_sesvars_to_all as parameters.
skygw_types.h: added array size counting macro.
Fix for broken replication has been added to mysql_monitor.
Both Slave_IO and Slave_SQL threads must be running in order to assign
the SERVER_SLAVE status but If only Slave_IO is running let’s assign
the master_id to current server and continue building the replication
tree; if no slaves at all the master will be still available.
The “detect_stale_master” option has been added, its default is 0.
If set to 1 the monitor will keep the last detected master even if the
replication setup is completely not working, i.e. both Slave_IO and
Slave_SQL threads are not running: this applies only to the server that
was master before.
After monitor or MaxScale are restarted and the replication is still
stopped or not configured there will be no master because it’s not
possible to compute the replication topology tree.
Only downstream filters are supported currently, i.e. no result
set filtering can be done.
A crude QLA (Query Log All) filter is included as a test harness only
The option is reloadable in the same way as max_slave_connections parameter. Option value determines which sort function is called before to sort backend server pointers before selecting them and establishing connections to backends.
In practice, 'reload config' reads config file and updates config parameters of rwsplit router service. In addition to that there is a version number indicating what generation of configuration service holds. When router instance is created (when MaxScale is started) service's config version is copied to router intance. Whenever new client connection (rwsplit session) is started, router instance's config version is checked against that of service's. If versions differ, service's config data is copied to router instance. New session will be started with router instance's config values.
