      Bug#44232 Error msg should be improved when collation not supported. · 5158be8f
      Narayanan V authored
      When a user selected an unsupported character set for an
      IBMDB2I table, error 2501 or 2511 may have been returned,
      giving the appearance of an internal programming error.
      
      This patch consolidates these errors into a single descriptive
      error message for the common case of an unsupported character
      set.
      
      The new error number is 2504 and indicates a user error.
      The errors 2501 and 2511 remain to indicate cases of internal
      programming errors.

      Bug#44352 UPPER/LOWER function doesn't work correctly · a5184bb3
      Alexander Barkov authored
      on cp932 and sjis environment.
      Problem: case conversion erroneously changes the second bytes
      of multi-byte sequences because single-byte functions were
      called in a mistake.
      Fix: call multi-byte aware functions instead.

      1. Replace waiting of SQL thread stop by waiting of SQL error on slave and stopped
      SQL thread.
      2. Remove debug code because it already implemented in MTR2.

      Bug#43737: Select query return bad result · 7d244411
      Martin Hansson authored
            
      A bug in the initialization of key segment information made it point
      to the wrong bit, since a bit index was used when its int value
      was needed. This lead to misinterpretation of bit columns
      read from MyISAM record format when a NULL bit pushed them over
      a byte boundary.
      Fixed by using the int value of the bit instead.

      Bug#43932 myisam index corruption with large index and large · 57b4295d
      Vladislav Vaintroub authored
      key_buffer_size.
      
      The cause of corruption was number overflow when multiplying 
      two ulong values, number of used keycache blocks with size
      of a single block. The result of multiplication exceeded ulong 
      range (4G) and this lead to incorrectly calculated  buffer offset
      in the key cache.
      
      The fix is to use size_t for multiplication result.
      
      This patch also fixes pointless cast in safemalloc 
      (size of allocated block to uint), that creates lot of false
      alarm warnings when using big keycache (> 4GB) in debug mode.

      Bug#44337 Select query using index merge fails with MCH3601 · f51e62cf
      Narayanan V authored
      The storage engine was not correctly handling the case in 
      which rnd_pos is executed for a handler without a preceding
      rnd_next or index read operation. As a result, an unitialized
      file handle was sometimes being passed to the QMY_READ API.
      
      The fix clears the rrnAssocHandle at the beginning of each
      read operation and then checks to see whether it has been
      set to a valid handle value before attempting to use it
      in rnd_pos. If rrnAssocHandle has not been set by a previous
      read operation, rnd_pos instead falls back to the use of the
      currently active handle.
