################################################################################ # Scenario: # SigCon= ({R(B), W(B)}) # GroupRepApplier=({R(B), W(B), C}, HIGH_PRIORITY). # # Outcome: SigCon must abort, THe GroupRepApplier must commit. # # Full details on WL#6835. # # Test: # 0. The test requires two servers: M1 and M2. # 1. With both members ONLINE. On M1 create table t1 and insert value 0 in # column c1. # 2. On M2, create SIGCON connection using DEBUG point. # 3. On M2, send update c1 from 0 to 99. # 4. On M1, update c1 from 0 to 1. # 5. On M2, wait for c1 to be 1. # 6. On M2, now signal the waiting thread on sigcon to resume and it should # end up in an error stating that it was aborted. # 7. On M2, reap. It should error out on COMMIT. # 8. Validate data in c1. It should be 1 on M2. # 9. Clean up. ################################################################################ --source include/have_debug.inc --source include/have_debug_sync.inc --let $group_replication_group_name= 8a94f357-aab4-11df-86ab-c80aa9429548 --source ../inc/have_group_replication_plugin.inc --source ../inc/group_replication.inc ####### SERVER 1 ####### --let $rpl_connection_name= server1 --source include/rpl_connection.inc CREATE TABLE t1 (c1 INT NOT NULL PRIMARY KEY) ENGINE=InnoDB; INSERT INTO t1 VALUES (0); ####### SIGCON (server2) ####### --let $rpl_connection_name= sigcon --let $rpl_server_number= 2 --source include/rpl_connect.inc --echo [connection sigcon] --let $sync_slave_connection= sigcon --source include/sync_slave_sql_with_master.inc SET DEBUG_SYNC='ha_innobase_end_statement WAIT_FOR waiting1'; BEGIN; --send UPDATE t1 SET c1=99 WHERE c1=0 ####### SERVER 2 ####### --let $rpl_connection_name= server2 --source include/rpl_connection.inc # Wait until sigcon reaches the ha_innobase_update_row_done debug sync point. --let $wait_condition=SELECT COUNT(*)=1 FROM INFORMATION_SCHEMA.PROCESSLIST WHERE State = 'debug sync point: ha_innobase_end_statement' --source include/wait_condition.inc ####### SERVER 1 ####### --let $rpl_connection_name= server1 --source include/rpl_connection.inc UPDATE t1 SET c1=1 WHERE c1=0; ####### SERVER 2 ####### --let $rpl_connection_name= server2 --source include/rpl_connection.inc # Wait for c1 in t1 to be 1 --let $wait_condition=SELECT COUNT(*)=1 FROM t1 WHERE c1=1 --source include/wait_condition.inc # Now signal the waiting thread on sigcon to resume # and it should end up in an error stating that it # was aborted SET DEBUG_SYNC='now SIGNAL waiting1'; ####### SIGCON ####### --echo [connection sigcon] --let $rpl_connection_name= sigcon --source include/rpl_connection.inc --reap --error ER_ERROR_DURING_COMMIT COMMIT; --disconnect sigcon ####### SERVER 2 ####### --connection server1 --let $sync_slave_connection= server2 --source include/sync_slave_sql_with_master.inc --let $assert_text= 'There is a 1 in t1' --let $assert_cond= [SELECT COUNT(*) AS count FROM t1 WHERE t1.c1 = 1, count, 1] = 1 --source include/assert.inc --let $assert_text= 'There is no 0 in t1' --let $assert_cond= [SELECT COUNT(*) AS count FROM t1 WHERE t1.c1 = 0, count, 1] = 0 --source include/assert.inc --let $assert_text= 'There is no 99 in t1' --let $assert_cond= [SELECT COUNT(*) AS count FROM t1 WHERE t1.c1 = 99, count, 1] = 0 --source include/assert.inc # Clean up. --connection server1 DROP TABLE t1; --source ../inc/group_replication_end.inc
