      Merge MySQL->MariaDB · dac8bb7f
      Sergey Petrunya authored
      * Finished Monty and Jani's merge
      * Some InnoDB tests still fail (because it's old xtradb code run against
        newer testsuite). They are expected to go after mergning with the latest
        xtradb.

      Bug#45010: invalid memory reads during parsing some strange statements · 357430de
      Davi Arnaut authored
      The problem is that the lexer could inadvertently skip over the
      end of a query being parsed if it encountered a malformed multibyte
      character. A specially crated query string could cause the lexer
      to jump up to six bytes past the end of the query buffer. Another
      problem was that the laxer could use unfiltered user input as
      a signed array index for the parser maps (having upper and lower
      bounds 0 and 256 respectively).
      
      The solution is to ensure that the lexer only skips over well-formed
      multibyte characters and that the index value of the parser maps
      is always a unsigned value.
      
      mysql-test/r/ctype_recoding.result:
        Update test case result: ending backtick is not skipped over anymore.
      sql/sql_lex.cc:
        Characters being analyzed must be unsigned as they can be
        used as indexes for the parser maps. Only skip over if the
        string is a valid multi-byte sequence.
      tests/mysql_client_test.c:
        Add test case for Bug#45010

      Bug#46454: MySQL wrong index optimisation leads to incorrect result & crashes · 1164f8a6
      Martin Hansson authored
      Problem 1:
      When the 'Using index' optimization is used, the optimizer may still - after
      cost-based optimization - decide to use another index in order to avoid using
      a temporary table. But when this happens, the flag to the storage engine to 
      read index only (not table) was still set. Fixed by resetting the flag in the 
      storage engine and TABLE structure in the above scenario, unless the new index
      allows for the same optimization.
      Problem 2:
      When a 'ref' access method was employed by cost-based optimizer, (when the column
      is non-NULLable), it was assumed that it needed no initialization if 'quick' access
      methods (since they are based on range scan). When ORDER BY optimization overrides 
      the decision, however, it expects to have this initialized and hence crashes. 
      Fixed in 5.1 (was fixed in 6.0 already) by initializing 'quick' even when there's 
      'ref' access. 
      
      mysql-test/r/order_by.result:

      sql/sql_select.cc:
        Bug#46454: 
        Problem 1 fixed in make_join_select()
        Problem 2 fixed in test_if_skip_sort_order()

        Bug#46454: Added comment to field.

      Fix for BUG#45816 - assertion failure with index containing double · ee9aff79
      Satya B authored
                          column on partitioned table
            
            
      An assertion 'ASSERT_COULUMN_MARKED_FOR_READ' is failed if the query 
      is executed with index containing double column on partitioned table.
      The problem is that assertion expects all the fields which are read,
      to be in the read_set.
            
      In this query only the field 'a' is in the readset as the tables in
      the query are joined by the field 'a' and so the assertion fails 
      expecting other field 'b'.
            
      Since the function cmp() is just comparison of two parameters passed, 
      the assertion is not required.
            
      Fixed by removing the assertion in the double fields comparision
      function and also fixed the index initialization to do ordered
      index scan with RW LOCK which ensures all the fields from a key are in
      the read_set.
       
      
      Note: this bug is not reproducible with other datatypes because the
            assertion doesn't exist in comparision function for other 
            datatypes.

      mysql-test/t/partition.test:
        Testcase for BUG#45816
      sql/field.cc:
        Removed the assertion ASSERT_COLUMN_MARED_FOR_READ in Field_double::cmp()
        function
      sql/ha_partition.cc:
        Fixed index_int() method to make it initialize the read_set properly if
        ordered index scan with RW lock is requested.

      Bug #45630 rpl_trigger.test causes valgrind failures within nptl_pthread_exit_hack_handler · 13c44afe
      unknown authored
      The server shutdown and start code triggered the valgrind failures 
      within nptl_pthread_exit_hack_handler on Ubuntu 9.04, x86 (but not amd64) 
      in rpl_trigger.test file.
      
      For fixing the bug, suppress valgrind failures within nptl_pthread_exit_hack_handler 
      on Ubuntu 9.04, x86 (but not amd64). Because the server shutdown and start
      code has been heavily used in mysql test set.
      
      mysql-test/valgrind.supp:
        Add code for suppressing valgrind failures within nptl_pthread_exit_hack_handler on Ubuntu 9.04, x86 (but not amd64).
