Wrong result with NOT IN + RIGHT JOIN + views

[Philip Stoev]

The following query:

SELECT * FROM v1, t2
WHERE t2.a NOT IN (
        SELECT t3.b
        FROM t3
        RIGHT JOIN t4 ON ( t4.d = t3.d )
        WHERE t4.d >= v1.d
);

returns 2 rows even though the same query using base table instead of a view v1 returns no rows. PostgreSQL also returns no rows in both cases.

test case:

CREATE TABLE t1 ( d varchar(32) , e int );
INSERT INTO t1 VALUES ('y',0),('w',0);

CREATE TABLE t2 ( a int , b int , c int , d varchar(1), e varchar(1));
INSERT INTO t2 VALUES (10,8,7,'b','b');

CREATE TABLE t3 ( a int , b int , c int , d varchar(1), e varchar(1));

CREATE TABLE t4 ( d varchar(32) , e int );
INSERT INTO t4 VALUES ('y',0),('w',0);

CREATE VIEW v1 AS SELECT * FROM t1;

SELECT * FROM v1, t2
WHERE t2.a NOT IN (
        SELECT t3.b
        FROM t3
        RIGHT JOIN t4 ON ( t4.d = t3.d )
        WHERE t4.d >= v1.d
);

Repeatable in maria-5.3, maria-5.2, mysql-5.5

A fix for the bug was pushed into the 5.3 tree.
Probably it makes sense to downport the fix into 5.2 as well.
