Test phase 1 to make sure that natral deadlock in trigger SP execution is
handled correctly

CREATE TABLE t1(a INT);
CREATE TABLE t2(f1 INT, f2 INT, f3 INT);

BEGIN
INSERT INTO t2 VALUES(100, 200, 300);
UPDATE t2 SET f3 = f3 + 100;
END|

Test phase 2 to make sure that BF abort for SP execution is
handled correctly

SET SESSION wsrep_retry_autocommit = 0;
SET SESSION wsrep_sync_wait = 0;
CREATE TABLE t1 (f1 INTEGER PRIMARY KEY, f2 CHAR(1));

UPDATE t1 SET f2='c';

Test phase 3 to make sure natural deadlock is not treated as BF abort

TRUNCATE t1;
INSERT INTO t1 VALUES (1, 'a'), (2, 'a');
connection node_1a;

is not treated as BF abort
