More small fixes to the API : use LEX_STRING instead of LEX_STRING* and if error then return bool(true) instead of error code. Merged functions. Reduced usage of sp_name. Fixed a lot of function documentation errors. Added function documentation wherever needed. Removed some unused defines and error codes. Next to come is batch rename of Event_scheduler_ng to Event_scheduler. mysql-test/r/events.result: update result mysql-test/r/events_logs_tests.result: update result mysql-test/t/events.test: more test coverage mysql-test/t/events_logs_tests.test: fix test sql/event_data_objects.cc: Cosmetics. Fix function documentation whenever needed. Move Event_job_data::compile() next to Event_job_data::execute() sql/event_data_objects.h: Remove unneeded error codes and defines Move function declarations at the end of the header sql/event_db_repository.cc: Fix function documentation. Event_db_repository::update_event() now uses LEX_STRING *-s instead of sp_name . Lower coupling. sql/event_db_repository.h: Event_db_repository::update_event() now uses LEX_STRING *-s instead of sp_name . Lower coupling. find_event -> find_named_event find_event_by_name is not used externally, merge with load_named_event() sql/event_queue.cc: LEX_STRING* to LEX_STRING Fix comments. Fix and add function documentation. Remove Event_queue::events_count() as it is unused Change get_top_for_execution_if_time() to return status code as return value and the object is in out parameter. sql/event_queue.h: LEX_STRING* to LEX_STRING Fix comments. Fix and add function documentation. Remove Event_queue::events_count() as it is unused Change get_top_for_execution_if_time() to return status code as return value and the object is in out parameter. Try to detect also lock attemptions for deadlocks. sql/event_scheduler_ng.cc: Always execute on thd->mem_root Fix according to changed API of Event_queue::get_top_for_execution_if_time() sql/events.cc: Fix function documentation. Fix code after API changes of internal Event module classes. sql/events.h: sp_name -> LEX_STRINGs sql/sql_parse.cc: Fix according to changed API of Events::show_create_event() sql/sql_yacc.yy: Don't pass NULL as third parameter to sp_head::init_strings()
