* MDEV-334: Backport of UNION ALL optimization from mysql-5.7.Igor Babaev2014-10-141-3/+3
| | | | | | Although the original code of mysql-5.7 was adjusted to the current MariaDB code the main ideas of the optimization were preserved.

| | | * MDEV-5581: Server crashes in in JOIN::prepare on 2nd execution of PS with ↵Sergey Petrunya2014-02-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | materialization+semijoin - The problem was that JOIN::prepare() tried to set TABLE::maybe_null for a table in join. Non-merged semi-join tables 1) are present as join's base tables on second EXECUTE, but 2) do not yet have a TABLE object. Worked around the problem by putting mixed_implicit_grouping into JOIN object, and then passing it to JTBM tables in setup_jtbm_semi_joins().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - convert_subq_to_sj() must connect child select's tables into parent select's TABLE_LIST::next_local chain. - The problem was that it took child's leaf_tables.head() which is different. This could cause certain tables (in this bug's case, child select's non-merged semi-join) not to be present in TABLE_LIST::next_local chain. Which would cause non-merged semi-join not to be initialized in setup_tables(), which would lead to NULL pointer dereference.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | constant table - Don't pull out a table out of a semi-join if it is on the inner side of an outer join. - Make join->sort_by_table= get_sort_by_table(...) call after const table detection is done. That way, the value of join->sort_by_table will match the actual execution. Which will allow the code in setup_semijoin_dups_elimination() (search for "Make sure that possible sorting of rows from the head table is not to be employed." to see that "Using filesort" is going to be used together with Duplicate Elimination ( and change it to Using temporary + Using filesort)
