Description: ============ To change 'CONSERVATIVE' @@global.slave_parallel_mode default to 'OPTIMISTIC' in 10.5. @sql/sys_vars.cc Changed default parallel_mode to 'OPTIMISTIC' @sql/rpl_filter.cc Changed default parallel_mode to 'OPTIMISTIC' @sql/mysqld.cc Removed the initialization of 'SLAVE_PARALLEL_CONSERVATIVE' to 'opt_slave_parallel_mode' variable. @mysql-test/suite/rpl/t/rpl_parallel_mdev6589.test @mysql-test/suite/rpl/t/rpl_mdev6386.test Added 'mtr' suppression to ignore 'ER_PRIOR_COMMIT_FAILED'. In case of 'OPTIMISTIC' mode if a transaction gets killed during "wait_for_prior_commit" it results in above error "1964". Hence suppression needs to be added for this error. @mysql-test/suite/rpl/t/rpl_parallel_conflicts.test Test has a 'slave.opt' which explicitly sets slave_parallel_mode to 'conservative'. When the test ends this mode conflicts with new default mode. Hence check test case reports an error. The 'slave.opt' is removed and options are set and reset within test. @mysql-test/suite/multi_source/info_logs.result @mysql-test/suite/multi_source/reset_slave.result @mysql-test/suite/multi_source/simple.result Result content mismatch in "show slave status" output. This is expected as new slave_parallel_mode='OPTIMISTIC'. @mysql-test/include/check-testcase.test Updated default 'slave_parallel_mode' to 'optimistic'. Refactored rpl_parallel.test into following test cases. Test case 1: @mysql-test/suite/rpl/t/rpl_parallel_domain.test Test case 2: @mysql-test/suite/rpl/t/rpl_parallel_domain_slave_single_grp.test Test case 3: @mysql-test/suite/rpl/t/rpl_parallel_single_grpcmt.test Test case 4: @mysql-test/suite/rpl/t/rpl_parallel_stop_slave.test Test case 5: @mysql-test/suite/rpl/t/rpl_parallel_slave_bgc_kill.test Test case 6: @mysql-test/suite/rpl/t/rpl_parallel_gco_wait_kill.test Test case 7: @mysql-test/suite/rpl/t/rpl_parallel_free_deferred_event.test Test case 8: @mysql-test/suite/rpl/t/rpl_parallel_missed_error_handling.test Test case 9: @mysql-test/suite/rpl/t/rpl_parallel_innodb_lock_conflict.test Test case 10: @mysql-test/suite/rpl/t/rpl_parallel_gtid_slave_pos_update_fail.test Test case 11: @mysql-test/suite/rpl/t/rpl_parallel_wrong_exec_master_pos.test Test case 12: @mysql-test/suite/rpl/t/rpl_parallel_partial_binlog_trans.test Test case 13: @mysql-test/suite/rpl/t/rpl_parallel_ignore_error_on_rotate.test Test case 14: @mysql-test/suite/rpl/t/rpl_parallel_wrong_binlog_order.test Test case 15: @mysql-test/suite/rpl/t/rpl_parallel_incorrect_relay_pos.test Test case 16: @mysql-test/suite/rpl/t/rpl_parallel_retry_deadlock.test Test case 17: @mysql-test/suite/rpl/t/rpl_parallel_deadlock_corrupt_binlog.test Test case 18: @mysql-test/suite/rpl/t/rpl_parallel_mode.test Test case 19: @mysql-test/suite/rpl/t/rpl_parallel_analyze_table_hang.test Test case 20: @mysql-test/suite/rpl/t/rpl_parallel_record_gtid_wakeup.test Test case 21: @mysql-test/suite/rpl/t/rpl_parallel_stop_on_con_kill.test Test case 22: @mysql-test/suite/rpl/t/rpl_parallel_rollback_assert.test
