BUG#37051 Replication rules not evaluated correctly
The problem of this bug is that we need to get the list of tables to be updated for a multi-table update statement, which requires to open all the tables referenced by the statement and resolve all the fields involved in update in order to figure out the list of tables for update. However if there are replicate filter rules, some tables might not exist on slave and result in a failure before we could examine the filter rules. I think the whole problem can not be solved on slave alone, the master must record and send the information of tables involved for update to slave, so that the slave do not need to open all the tables referenced by the multi-table update statement to figure out which tables are involved for update. So a status variable is added to Query_log event to store the value of table map for update on master. And on slave, it will try to get the value of this variable and use it to examine filter rules without opening any tables on slave, if this values is not available, the old approach is used and thus the bug will still occur for when replicating from old masters. sql/sql_class.h: add member table_map_for_update to THD sql/sql_parse.cc: check filter rules by using table_map_for_update value sql/sql_update.cc: save the value of table_map_for_update
