server.h:added macro SERVER_IS_ROOT_MASTER for finding valid candidate for root master
readwritesplit.c: wrote open three if conditions in get_root_master_bref for clarity
All counters are now updated in routeQuery
Fix to bug #545, http://bugs.skysql.com/show_bug.cgi?id=545
All sql variable and session modification statements, such as autocommit-, and set <db> commands are routed to all nodes.
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
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
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.
query_classifier.h: added QUERY_TYPE_CREATE_TMP_TABLE and QUERY_TYPE_READ_TMP_TABLE for use of temporary table support.
hashtable.c:Added variant of hashtable which is 'flat', that is, stored to existing memory instead of allocating memory as a part of the call. Existing function declarations don't change but added hashtable_alloc_flat for the purpose. Both hashtable_alloc and hashtable_alloc_flat now call the real allocation function, hashtable_alloc_real. hashtable_free only frees memory which is allocated in hashtable_alloc_real.
hashtable.h: added a flag to HASHTABLE struct to indicate whether hashtable owns its memory or not.
readwritesplit.h: Added RSES_PROP_TYPE_TMPTABLES property type to be used for keeping the hashtable for tablenames.
readwritesplit.c: Added comments about temporary table support implementation.
