Long ~0.5MB queries blocked MaxScale.
mysql_client.c:gw_read_client_event: Fixed packet reading logic. Reading didn't work when packet exceeded read buffer size.
mysql_common.c:gw_MySQL_get_next_packet: number of bytes to be copied to continuous buffer was calculated wrong, thus resulting in broken packet.
readwritesplit.c:disabled creation of canonical query in debug build because it slows down the processing too much with long queries
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/modules/filter/Makefile: Added path to libmysqld (-L<path>) so that linker finds it at compile time.
server/test/MaxScale_template.cnf: added write_ses_variables_to_all=Yes and read_ses_variables_from_slaves=Yes so that tests included in testall target succeed (at server/modules/routing/readwritesplit/test). Added hint filter to 'normal' rwsplit service.
Added description of new rwsplit variables, read_ses_variables_from_slaves and write_ses_variables_to_all to MaxScale_template.cnf
readwritesplit.h:Set default values for write_ses_variables_to_all=true, and read_ses_variables_from_slaves=false
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.
query_classifier.cc: updated skygw_get_table_names to allow for partial or full table names
readwritesplit.c: transferred temporary table detection to separate functions
- Monitor automatically builds the replication topology tree if at least Slave_IO thread is running in slaves and the master server will be available.
- If the replication is stopped or configuration removed the previos master server may be still available with detect_stale_master=1
The SERVER_STALE_STATUS bit is added to the server->status field
Monitor diagnostic routine print all new status descriptions
Includes imprvements to hints processing. If hint can't be followed query is routed possibly to slave, and eventually to master if other attempts fail.
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.
