# # ==== Purpose ==== # # This test checks if the sql delay is being applied in a simple master-slave # topology. # # ==== Implementation ==== # # The SQL_Delay is set to 5 seconds. # For each for the six different transactions executed (two DDL, three DML and # one multi-statement DML), the test verifies if the delay was the expected using # replication timestamp infrastructure introduced by WL#7319. # # ==== References ==== # # WL#7318 Delayed Replication: GTID based and relative to immediate master commit # This test is very unstable when using windows because support for high # precision timestamps in this platform is not as good as in unix --source include/not_windows.inc # There is a specific test for mts --source include/not_mts_slave_parallel_workers.inc --source include/have_debug.inc --let $rpl_skip_start_slave= 1 --source include/master-slave.inc --let $delay= 7 --let $slave_sleep= 2 --source include/rpl_connection_slave.inc --eval CHANGE MASTER TO MASTER_DELAY= $delay source include/start_slave.inc; # Verify that the DESIRED_DELAY in replication_applier_configuration table # of performance_schema and SQL_Delay field of show slave status has the # same value as the delay set through the master_delay of the CHM command. --let $desired_delay= query_get_value(select *from performance_schema.replication_applier_configuration,DESIRED_DELAY,1) --let $assert_text= Assert that the desired delay from performance_schema is same as set in the Change master to command. --let $assert_cond= $desired_delay = $delay --source include/assert.inc --let $sql_delay= query_get_value(show slave status,SQL_Delay,1) --let $assert_text= Assert that the sql_delay in show slave status is same as set in the Change master to command. --let $assert_cond= $sql_delay = $delay --source include/assert.inc --let $debug_point= sql_delay_without_timestamps --source include/add_debug_point.inc --source include/rpl_connection_master.inc # $time_1 is collected in the same server as $time_2 # Since the delay is relative to the master's clock, we collect the time in # master --let $time_1= `SELECT SYSDATE(6)` CREATE TABLE t1 (a INT); --source extra/rpl_tests/check_slave_delay_old.inc INSERT INTO t1 VALUES (1); --source extra/rpl_tests/check_slave_delay_old.inc UPDATE t1 SET a=2; --source extra/rpl_tests/check_slave_delay_old.inc DELETE FROM t1 WHERE a=2; --source extra/rpl_tests/check_slave_delay_old.inc START TRANSACTION; INSERT INTO t1 VALUES (1); INSERT INTO t1 VALUES (2); INSERT INTO t1 VALUES (3); COMMIT; --source extra/rpl_tests/check_slave_delay_old.inc DROP TABLE t1; --source extra/rpl_tests/check_slave_delay_old.inc # Cleanup --source include/rpl_connection_slave.inc --source include/remove_debug_point.inc --source include/stop_slave_sql.inc CHANGE MASTER TO MASTER_DELAY= 0; --source include/start_slave_sql.inc --source include/rpl_connection_master.inc --source include/rpl_end.inc
