      Bug#20086: Can't get data from key partitioned tables with VARCHAR key · 4e138572
      unknown authored
      The problem appeared because the same values produced different hash
      during INSERT and SELECT for VARCHAR data type.
      Fix:
      VARCHAR required special treatment to avoid hashing of length bytes
      (leftmost one or two bytes) as well as trailing bytes beyond real length,
      which could contain garbage. Fix is done by introducing hash() - new method
      in the Field class.

        Adding test case

        Fixing test results (results differ due to changes in hash function)

        Adding test case
      sql/field.cc:
        Adding generic hash() method, and a special
        method for VARCHAR.
      sql/field.h:
        Adding prototypes for new methods
      sql/key.cc:
        Mark columns for write before executinf of set_key_image().
        Thanks for Mikael for suggesting this fix.
      sql/sql_partition.cc:
        Removing old hash code.
        Using new methid field->hash() instead.
