################################################################################ # BUG#21142784 - CRASH ON 'START/STOP SLAVE FOR CHANNEL' AND 'START/STOP # GROUP_REPLICATION' # BUG#21154282 - RSA..CHANNEL 'GROUP_REPLICATION_APPLIER' SHOULD NOT BE ALLOWED # WITHOUT STOP GR # # This test checks to see that user should not be allowed to execute # set of commands for the group_replication_applier channel. # # a). When group_replication is ONLINE. # b). when group_replication is OFFLINE. # # Test: # 0. The test requires two servers: M1 and M2. # # 1. Start GR on member i.e. make M1 ONLINE. Now, check the execution of # following commands on the GR channels. # a) CHM is blocked on group_replication_applier # b) FLUSH RELAY LOGS is blocked on group_replication_applier # c) START SLAVE IO_THREAD is blocked on group_replication_applier # d) START SLAVE IO_THREAD with UNTIL option is blocked on # group_replication_applier # e) STOP SLAVE IO_THREAD is blocked on group_replication_applier # f) START SLAVE is blocked on group_replication_applier # g) STOP SLAVE is blocked on group_replication_applier # h) SHOW SLAVE STATUS is blocked on group_replication_applier # i) START SLAVE SQL_THREAD is allowed on group_replication_applier # j) START SLAVE SQL_THREAD with UNTIL option is allowed on # group_replication_applier # k) STOP SLAVE SQL_THREAD is allowed on group_replication_applier # l) SHOW RELAYLOG EVENTS is allowed on group_replication_applier # # 2.

Start GR on M1. Connect to M2 which is ONLINE. # a) RESET SLAVE ALL is blocked on group_replication_applier # b) RESET SLAVE is blocked on group_replication_applier # # 4. Stop GR on M2 (OFFLINE). # a) RESET SLAVE is allowed on group_replication_applier # # 5. Start GR on M2 (ONLINE). # a) RESET SLAVE is blocked on group_replication_applier # # 6. Stop GR on M2 (OFFLINE). # a) RESET SLAVE ALL is allowed on group_replication_applier # # 7. Start GR on M2 (ONLINE). STOP SLAVE SQL_THREAD on the channel. Then, # a) RESET SLAVE is blocked on group_replication_applier # b) RESET SLAVE ALL is blocked on group_replication_applier # # 8. START SLAVE SQL_THREAD on the channel. Stop GR on M2 (OFFLINE). Then, # a) RESET SLAVE ALL is allowed on group_replication_applier # b) RESET SLAVE - check that channel doesn't exists ################################################################################ --source include/big_test.inc --source ../inc/have_group_replication_plugin.inc --source ../inc/group_replication.inc --let $rpl_connection_name= server1 --source include/rpl_connection.inc # Part 1 - Checking the execution of the command when group_replication is ON. --echo --echo # CHANGE MASTER command is blocked for restricted channels. --error ER_SLAVE_CHANNEL_NAME_INVALID_OR_TOO_LONG CHANGE MASTER TO MASTER_HOST="localhost", MASTER_PORT=10 FOR CHANNEL "group_replication_applier";
