MDEV-6830: Server crashes in best_access_path after a sequence of SELECTs ... generate_derived_keys_for_table() did not work correctly in the case where - it had a potential index on derived table - however, TABLE::check_tmp_key() would disallow creation of this index after looking at its future key parts (because of the key parts exceeding max. index length) - the code would leave a KEYUSE structure that refers to a non-existant index. Depending on further optimizer calculations, this could cause a crash.	Sergey Petrunya	9 years ago

MDEV-7068: MRR accessing uninitialised bytes, test case failure main.innodb_mrr Backport to 5.3: - Don't call index_reader->interrupt_read() if the index reader has returned all rows that matched its keys.

3795	Fixed bug mdev-6705. Fixed bug mdev-6705. After constant row substitution the WHERE condition may be simplified and its multiple equality may be changed. In this case the references to these multiple equalities from the COND_EQUAL objects associated with ON expressions must be updated. Also we have to take into account that this simplification may lead to equalities of the form field=const that are mutually exclusive with some of the equalities in ON expressions.

3794	Fixed bug mdev-6292. Fixed bug mdev-6292. Avoided exponential recursive calls of JOIN_CACHE::join_records() in the case of non-nested outer joins. A different solution is required to resolve this performance problem for nested outer joins.	Igor Babaev	9 years ago
