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 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
