In the code that converts IN predicates to EXISTS predicates it is changing the select list elements to constant 1. Example : SELECT ... FROM ... WHERE a IN (SELECT c FROM ...) is transformed to : SELECT ... FROM ... WHERE EXISTS (SELECT 1 FROM ... HAVING a = c) However there can be no FROM clause in the IN subquery and it may not be a simple select : SELECT ... FROM ... WHERE a IN (SELECT f(..) AS c UNION SELECT ...) This query is transformed to : SELECT ... FROM ... WHERE EXISTS (SELECT 1 FROM (SELECT f(..) AS c UNION SELECT ...) x HAVING a = c) In the above query c in the HAVING clause is made to be an Item_null_helper (a subclass of Item_ref) pointing to the real Item_field (which is not referenced anywhere else in the query anymore). This is done because Item_ref_null_helper collects information whether there are NULL values in the result. This is OK for directly executed statements, because the Item_field pointed by the Item_null_helper is already fixed when the transformation is done. But when executed as a prepared statement all the Item instances are "un-fixed" before the recompilation of the prepared statement. So when the Item_null_helper gets fixed it discovers that the Item_field it points to is not fixed and issues an error. The remedy is to keep the original select list references when there are no tables in the FROM clause. So the above becomes : SELECT ... FROM ... WHERE EXISTS (SELECT c FROM (SELECT f(..) AS c UNION SELECT ...) x HAVING a = c) In this way c is referenced directly in the select list as well as by reference in the HAVING clause. So it gets correctly fixed even with prepared statements. And since the Item_null_helper subclass of Item_ref_null_helper is not used anywhere else it's taken out.

Supplying --skip-rpl to mysql-test-run.pl would always disable the slaves, but those slaves may still be needed for the federated tests. Now we only disable the slaves when they are not used by any of the tests.

Add test to mysql-test-run.pl to see if the udf_example.so is availble. Set envioronment variable UDF_EXAMPLE_LIB if it is. Then check in have_udf if that variable is set. Finally use tahe variable when loading the shared library.
