RATHER THAN A TABLE Problem: In RBR, If a table is converted into a view at slave, (i.e., "drop table 'object1'" & "create view 'object1'"), then any DML operations on the table at master are causing crash at slave. Analysis: Slave prepares tables to be opened for DML list when it receives Table_map_log_event(s). And the same list will be sent to open_table function. Open_table logic assumes that if the list contains a view object, it also contains "select_lex" object of that view. In the above special case, the table object does not contain 'select_lex' as it is base table at master. Since it is a view at slave, open_table logic goes to 'mysql_make_view()' function which assumes that 'select_lex' exists for the object. Fix: While preparing 'tables to be opened' list, we should make sure that table required type is 'base table'. If it is not base table while opening the object, mysql_make_view will throw an error similar to 'object is not a base table' sql/log_event.cc: Restrict that all table_map_log_event's objects should be base tables @ slave also.
