This bug was introduced when the patch resolving the performance problem 17164 was applied. As a result of that modification the not_null_tables attributes were calculated incorrectly for constant OR conditions. This triggered invalid conversion of outer joins into inner joins. mysql-test/r/join_outer.result: Added a test case for bug #19816. mysql-test/t/join_outer.test: Added a test case for bug #19816.
