################################################################################ # WL#7660 - GCS PLUGIN IMPLEMENTATION # # This test checks the basic functionality of the Group Replication replication # plugin: the installation, uninstallation of the plugin and the # update of the plugin status variables. # # Test: # 0. The test requires one server. # 1. Set group_replication_group_name=<INVALID_VALUE>. Expect error. # 2. Set group_replication_group_name=<VALID_VALUE>. Assert check the value. # - Set group_replication_start_on_boot=1. Assert check the value. # 3. Restart server to check that plugin is still loaded. # 4. After the server restart the group name is again set to NULL. Thus, START # GROUP_REPLICATION (GR) command must fail. # 5. Start GR command will succeed when group name is set to valid value. # 6. Try start GR command again. It must error out since the group is already # running. Start GR with valid value. It must start. # 7. Set group_replication_group_name=<VALID_VALUE>. It must error out i.e. we # cannot set group name when group is running. # 8. Clean up. ################################################################################ --let $group_replication_group_name= 8a94f357-aab4-11df-86ab-c80aa9429563 --source ../inc/have_group_replication_plugin.inc SET SESSION sql_log_bin= 0; call mtr.add_suppression("The group name *.*"); SET SESSION sql_log_bin= 1; --error ER_WRONG_VALUE_FOR_VAR SET GLOBAL group_replication_group_name= "8a94f357-aab4-11df-86ab-invalid"; # This is a valid name being given to the group name --eval SET GLOBAL group_replication_group_name= "$group_replication_group_name" --eval SET GLOBAL group_replication_start_on_boot= 1 --let $assert_text= The value of group name should be $group_replication_group_name --let $assert_cond= "[SELECT @@group_replication_group_name]" = "$group_replication_group_name" --source include/assert.inc --let $assert_text= The value of group_replication_start_on_boot should be 1 --let $assert_cond= [SELECT @@group_replication_start_on_boot] = 1 --source include/assert.inc # This restart tests that the plugin is still loaded on the server restart # Also it checks the shutdown hook that is provided as a part of WL#6821. --let $_group_replication_local_address= `SELECT @@GLOBAL.group_replication_local_address` --let $_group_replication_group_seeds= `SELECT @@GLOBAL.group_replication_group_seeds` --let $_group_replication_group_whitelist= `SELECT @@GLOBAL.group_replication_ip_whitelist` --let $restart_parameters=restart:--group_replication_local_address=$_group_replication_local_address --group_replication_group_seeds=$_group_replication_group_seeds --group_replication_bootstrap_group=1 --group_replication_ip_whitelist=$_group_replication_group_whitelist --replace_result $_group_replication_local_address GROUP_REPLICATION_LOCAL_ADDRESS $_group_replication_group_seeds GROUP_REPLICATION_GROUP_SEEDS $_group_replication_group_whitelist GROUP_REPLICATION_GROUP_WHITELIST --source include/restart_mysqld.inc # After the server restart the group name is again set to NULL which will # cause an error due to wrong configuration. --error ER_GROUP_REPLICATION_CONFIGURATION START GROUP_REPLICATION; --source include/start_group_replication.inc # This start command will error out since the group is already running. --error ER_GROUP_REPLICATION_RUNNING START GROUP_REPLICATION; # We cannot set group name when group is running. # Proper message will be logged on error log. --error ER_GROUP_REPLICATION_RUNNING --eval SET GLOBAL group_replication_group_name= "$group_replication_group_name" --source include/stop_group_replication.inc RESET SLAVE ALL FOR CHANNEL "group_replication_applier"; --source ../inc/gr_clear_configuration.inc
