################################################################################ # This test verifies whether the group_replication works fine when majority loss # occurs while there are dml operations running on some server # # Test: # 0. The test requires two servers: M1 and M2. # 1. Start the group_replication on all the servers. # 2. CREATE TABLE ON M1 and CREATE a procedure to perform the dml operations # on the table # 3. Call the procedure using send operation # 4. Kill and restart the server M2 # 5. Wait until server M2 is in UNREACHABLE state. # 6. SET group_replication_force_members value as local_address of server M1 # 7. Start GR on server M2. # 8. Obtain the result of send command on M1 and wait until both # the servers are ONLINE. # 9. Verify that table t1 has same data across all the members. # 10.Clean up ################################################################################ # This test does crashes servers, thence we skip it on asan and valgrind. --source include/not_asan.inc --source include/not_valgrind.inc --source include/big_test.inc --source include/force_restart.inc --source ../inc/have_group_replication_plugin.inc --source ../inc/group_replication.inc --let $rpl_connection_name= server1 --source include/rpl_connection.inc # Save the local address of server1 --let $local_address_server1= `SELECT @@GLOBAL.group_replication_local_address` CREATE TABLE t1(a int primary key); --source include/rpl_sync.inc # Create a procedure to perform the dml operations. delimiter $$; CREATE PROCEDURE dml_operations() BEGIN declare x INT; set x=1; while x<300 do insert into t1 values (x); update t1 set a=x+300 where a=x; delete from t1 where a<310; set x=x+1; end while; end$$ delimiter ;$$ --echo --echo ----call procedure---- --send call dml_operations() --echo --let $rpl_connection_name= server2 --source include/rpl_connection.inc set sql_log_bin=0; call mtr.add_suppression(".*Slave SQL for channel 'group_replication_applier': ...
