Sergei Golubchik	72b5b8b2e3	MDEV-27434 DESC attribute does not work with auto-increment on secondary column of multi-part index ... when searching for the last auto-inc value, it's HA_READ_PREFIX_LAST for the ASC keypart, but HA_READ_PREFIX for the DESC one also fixes MDEV-27585	2022-01-26 18:43:06 +01:00
Sergei Golubchik	ddbb3d1447	MDEV-27309 Server crash or ASAN memcpy-param-overlap upon INSERT into Aria/MyISAM table with DESC key ... MyiSAM and Aria, indexes with prefix compression, where the first keypart could be NULL - in this case they didn't expect the next key after the not NULL key to be NULL. Expect the first keypart of the next key to have zero length even if store_not_null==1, this combination means keypart is NULL, don't pack it. also fixes MDEV-27340	2022-01-26 18:43:06 +01:00
Sergei Golubchik	775e7ce6d6	MDEV-27303 Table corruption after insert into a non-InnoDB table with DESC index ... optimized prefix search didn't take into account descending indexes also fixes MDEV-27330	2022-01-26 18:43:06 +01:00
