Notable Items

InnoDB

  • InnoDB no longer acquires advisory file locks by default (MDEV-24393)
  • Encryption: Automatically disable key rotation checks for file_key_management plugin (MDEV-14180)
  • Some fixes from MySQL 5.7.35 (MDEV-26205)
  • Fixed scrubbing on AIX (MDEV-26110)
  • buf_pool.flush_list corrupted by buffer pool resizing or ROW_FORMAT=COMPRESSED (MDEV-26200)

Optimizer

  • A query that uses ORDER BY .. LIMIT clause and "Range checked for each record optimization" could produce incorrect results under some circumstances (MDEV-25858)
  • Queries that have more than 32 equality conditions comparing columns of different tables ("tableX.colX=tableY.colY) could cause a stack overrun in the query optimizer (MDEV-17783, MDEV-23937)
  • "Condition pushdown into derived table" optimization cannot be applied if the expression being pushed refers to a derived table column which is computed from expression that has a stored function call, @session variable reference, or other similar construct. The fix for MDEV-25969 makes it so that only the problematic part of the condition is not pushed. The rest of the condition is now pushed. (MDEV-25969)
  • A query with window function on the left side of the subquery could cause a crash. (MDEV-25630)
  • Fixed the issue fixed in MySQL Bug #76803: DML or locking SELECT statements that use outer joins could produce this warning in the error log: [ERROR] InnoDB: Unlock row could not find a 3 mode lock on the record. (MDEV-26106)
