############################################################################### # Bug#27368735 BINLOG NAME AND POS ARE WRONG IN GROUP_REPLICATION_APPLIER # CHANNEL'S ERROR MSGS # Problem: When group_replication_applier channel's applier thread is facing # an error, master_log_name and end_log_pos in the error message # are incorrect. # # Steps to reproduce: # =================== # 0) Test require two servers in the group # 1) Create a table with a primary key on both servers. # 2) Have a tuple with key '1' on server2. # 3) Insert the same tuple on server1 and try to sync on server2. # 4) Sync (applier thread on server2) will fail because of # the duplicate key error. # 5) Check that the error says master_log_name and end_log_pos as # instead of displaying wrong values. # 6) Cleanup (drop table on both servers) ############################################################################### --source include/only_mts_slave_parallel_workers.inc --source include/have_group_replication_plugin.inc --source include/group_replication.inc --echo # --echo # Step-1: Initial setup (create table on both servers) --echo # --let $rpl_connection_name= server_1 --source include/rpl_connection.inc CREATE TABLE t1(i INT PRIMARY KEY); --source include/rpl_sync.inc --echo # --echo # Step-2: Insert a tuple on server2 directly without writing --echo # into binlog. --echo # --let $rpl_connection_name= server_2 --source include/rpl_connection.inc SET sql_log_bin=0; INSERT INTO t1 values (1); --echo # --echo # Step-3: Add error suppressions which are required --echo # for the test to pass. --echo # CALL mtr.add_suppression("Could not execute Write_rows event on table test.t1"); CALL mtr.add_suppression("The applier thread execution was aborted.
