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.
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.
