Dead code cleanup: part_info->num_parts usage was wrong and working incorrectly in mysql_drop_partitions() because num_parts is already updated in prep_alter_part_table(). We don't have to update part_info->partitions because part_info is destroyed at alter_partition_lock_handling(). Cleanups: - DBUG_EVALUATE_IF() macro replaced by shorter form DBUG_IF(); - Typo in ER_KEY_COLUMN_DOES_NOT_EXITS. Refactorings: - Splitted write_log_replace_delete_frm() into write_log_delete_frm() and write_log_replace_frm(); - partition_info via DDL_LOG_STATE; - set_part_info_exec_log_entry() removed. DBUG_EVALUATE removed DBUG_EVALUTATE was only added for consistency together with DBUG_EVALUATE_IF. It is not used anywhere in the code. DBUG_SUICIDE() fix on release build On release DBUG_SUICIDE() was statement. It was wrong as DBUG_SUICIDE() is used in expression context.
