# ==== Purpose ==== # # Verify that INSERT DELAYED in mixed or row mode writes events to the # binlog, and that AUTO_INCREMENT works correctly. # # ==== Method ==== # # Insert both single and multiple rows into an autoincrement column, # both with specified value and with NULL. # # With INSERT DELAYED, the rows do not show up in the table # immediately, so we must do source include/wait_until_rows_count.inc # between any two INSERT DELAYED statements. Moreover, if mixed or # row-based logging is used, there is also a delay between when rows # show up in the table and when they show up in the binlog. To ensure # that the rows show up in the binlog, we call FLUSH TABLES, which # waits until the delayed_insert thread has finished. # # We cannot read the binlog after executing INSERT DELAYED statements # that insert multiple rows, because that is nondeterministic. More # precisely, rows may be written in batches to the binlog, where each # batch has one Table_map_log_event and one or more # Write_rows_log_event. The number of rows included in each batch is # nondeterministic. # # ==== Related bugs ==== # # BUG#20627: INSERT DELAYED does not honour auto_increment_* variables # Bug in this test: BUG#38068: binlog_stm_binlog fails sporadically in pushbuild create table t1 (a int not null auto_increment, primary key (a)) engine=myisam; let $table=t1; let $count=0; insert /* before delayed */ delayed /* after delayed */ into t1 values (207); inc $count; --source include/wait_until_rows_count.inc insert /*! delayed */ into t1 values (null); inc $count; --source include/wait_until_rows_count.inc insert delayed into t1 values (300); inc $count; --source include/wait_until_rows_count.inc # It is not enough to wait until all rows have been inserted into the # table.
