      MDEV-8289: Semijoin inflates number of rows in query result · 9b475ee3

      - Make semi-join optimizer not to choose LooseScan
        when 1) the index is not covered and 2) full index
        scan will be required.
      
      - Make sure that the code in make_join_select() that may change
        full index scan into a range scan is not invoked when the table
        uses full scan.

      Fixed overrun in key cache if one tried to allocate a key cache · afa9cb75
      Monty authored
      of more than 45G with a key_cache_block_size of 1024 or less.
      
      The problem was that some of the arguments to my_multi_malloc() got to be
      more than 4G.
      
      Fix:
      - Inntroduced my_multi_malloc_large() that can handle big regions.
      - Changed MyISAM and Aria key caches to use my_multi_malloc_large().
      
      I didn't change the default my_multi_malloc() as this would be a too big
      patch and we don't allocate 4G blocks anywhere else.

      MDEV-8302: Duplicate key with parallel replication · 9b9c5e89
      Kristian Nielsen authored
      This bug is essentially another variant of MDEV-7458.
      
      If a transaction conflict caused a deadlock kill of T2 in record_gtid()
      during commit, the code would do a rollback _before_ running
      rgi->unmark_start_commit(). This creates a race where following transactions
      could start too early (before T2 has completed its transaction retry). This
      in turn could lead to replication failure, if there was a conflict that
      caused eg. duplicate key error or similar.
      
      The fix is to remove these rollbacks (in Query_log_event::do_apply_event()
      and Xid_log_event::do_apply_event(). They seem out-of-place; code in
      log_event.cc generally does not roll back on error, this is handled higher
      up.
      
      In addition, because of the extreme difficulty of reproducing bugs like
      MDEV-7458 and MDEV-8302, this patch adds some extra precations to try to
      detect (in debug builds) or prevent (in release builds) similar bugs.
      ha_rollback_trans() will now call unmark_start_commit() if needed (and
      assert in debug build when a caller does rollback without unmark first).
      
      We also add an extra check for thd->killed() so that we avoid doing
      mark_start_commit() if we already have a pending deadlock kill.
      
      And we add a missing unmark_start_commit() call in the error case, found by
      the above assertion.
