################################################################################ # This test verifies whether the group_replication works fine when the server # in a group goes down while there are dml operations running on it. # # Test: # 0. The test requires three servers: M1,M2 and M3. # 1. Start GR on all the servers. # 2. CREATE TABLE ON M1 and CREATE a procedure to insert data # into the table # 3. Call the procedure using send operation and sleep for some time. # 4. Kill and restart the server M1. # 5. Wait until there are two members in a group # 6. Start GR on server M1. # 7. Verify that table t1 has same data across all the members. # 8. 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 --let $rpl_server_count= 3 --source ../inc/group_replication.inc --let $rpl_connection_name= server1 --source include/rpl_connection.inc set sql_log_bin=0; call mtr.add_suppression("Error in Log_event::read_log_event()"); set sql_log_bin=1; --let $group_replication_group_seeds= `SELECT @@GLOBAL.group_replication_group_seeds` --let $group_replication_local_address= `SELECT @@GLOBAL.group_replication_local_address` CREATE TABLE t1(a int auto_increment, primary key(a)); # Create the 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 --disable_query_log --let $i=30 while($i) { --EVAL INSERT INTO t1(a) VALUES(NULL); --dec $i } --enable_query_log --let $rpl_connection_name= server1 --source include/rpl_connection.inc # Wait until some data is entered into table t1 to ensure that the server1 # will get killed while there are dml operations running on it --let $wait_condition= SELECT COUNT(*) >20 FROM t1 --source include/wait_condition.inc # Kill server1 --echo # killing --let $restart_parameters=restart:--group_replication_local_address=$group_replication_local_address --group_replication_group_seeds=$group_replication_group_seeds --group_replication_group_name=$group_replication_group_name --replace_result $group_replication_local_address GROUP_REPLICATION_LOCAL_ADDRESS $group_replication_group_seeds GROUP_REPLICATION_GROUP_SEEDS $group_replication_group_name GROUP_REPLICATION_GROUP_NAME --source ../inc/kill_and_restart_mysqld.inc --echo # restarting --exec date # Needed as we are not using rpl_restart_server.inc --let $rpl_server_number= 1 --source include/rpl_reconnect.inc --let $rpl_connection_name= server2 --source include/rpl_connection.inc # Wait until group has only 2 members, that is, server1 death is detected by # the group. --echo # check that there are 2 members in the group --let $group_replication_number_of_members= 2 --source ../inc/gr_wait_for_number_of_members.inc # --let $rpl_server_number= 1 # --source include/rpl_reconnect.inc --let $rpl_connection_name= server2 --source include/rpl_connection.inc --let $_rpl_server_number = 2 while ($_rpl_server_number <= $rpl_server_count){ --let $rpl_connection_name= server$_rpl_server_number --source include/rpl_connection.inc --let $saved_read_only=`SELECT @@GLOBAL.super_read_only;` if (!$saved_read_only){ --EVAL INSERT INTO t1(a) VALUES(NULL); --exec date; } --inc $_rpl_server_number } --let $rpl_connection_name= server_1 --source include/rpl_connection.inc # START GR on server1 --source include/start_group_replication.inc # Sync all the servers. --source include/rpl_sync.inc # Verify that all the tables have same data. --let $diff_tables=server_1:t1, server2:t1, server3:t1 --source include/diff_tables.inc drop table t1; --source ../inc/group_replication_end.inc
