      Bug#10178 - failure to find a row in heap table by concurrent UPDATEs · a7e66efc
      unknown authored
      Moved the key statistics update to info().
      The table is not locked in open(). This made wrong stats possible.
      
      No test case for the test suite.
      This happens only with heavy concurrency.
      A test script is added to the bug report.
      
      
      mysql-test/r/heap_hash.result:
        Bug#10178 - failure to find a row in heap table by concurrent UPDATEs
        Updated test results to reflect the new  statistics behaviour.
      mysql-test/t/heap_hash.test:
        Bug#10178 - failure to find a row in heap table by concurrent UPDATEs
        Added a FLUSH TABLES to avoid statistics differences between normal 
        and ps-protocol tests.

        redefine 'new' before #include <asm/atomic.h> in any case.

      Fix for BUG#11185. · e4296f58
      unknown authored
      The source of the problem is in Field_longlong::cmp. If 'this' is
      an unsigned number, the method casts both the current value, and
      the constant that we compare with to an unsigned number. As a
      result if the constant we compare with is a negative number, it
      wraps to some unsigned number, and the comparison is incorrect.
      
      When the optimizer chooses the "range" access method, this problem
      causes handler::read_range_next to reject the current key when the
      upper bound key is a negative number because handler::compare_key
      incorrectly considers the positive and negative keys to be equal.
      
      The current patch does not correct the source of the problem in
      Field_longlong::cmp because it is not easy to propagate sign
      information about the constant at query execution time. Instead
      the patch changes the range optimizer so that it never compares
      unsiged fields with negative constants. As an added benefit,
      queries that do such comparisons will execute faster because
      the range optimizer replaces conditions like:
      (a) (unsigned_int [< | <=] negative_constant) == FALSE
      (b) (unsigned_int [> | >=] negative_constant) == TRUE
      with the corresponding constants.
      In some cases this may even result in constant time execution.
      
      
      mysql-test/r/range.result:
        - Changed incorrect result of an old test
        - Added new results for BUG#11185
      mysql-test/t/range.test:
        - Added new tests for BUG#11185
        - Deleted an old comment because now the problem is fixed
      sql/opt_range.cc:
        Added a new optimization to the range optimizer where we detect that
        an UNSIGNED field is compared with a negative constant. Depending on
        the comparison operator, we know directly that the result of the
        comparison is either TRUE or FALSE for all input values, and we need
        not check each value.
        
        This optimization is also necessary so that the index range access
        method produces correct results when comparing unsigned fields with
        negative constants.
