      Bug#46051: Incorrectly market field caused wrong result. · 50323800
      Evgeny Potemkin authored
      When during the optimization an item is moved to the upper select
      the item's context left unchanged. This caused wrong result in the 
      PS/SP mode.
      The Item_ident::remove_dependence_processor now sets the context
      of the select to which the item is moved to.

        The test case for the bug#46051 is adjusted.

      In a subselect all fields from outer selects are marked as dependent on
      selects they are belong to. In some cases optimizer substitutes it for an
      equivalent expression. For example "a_field IN (SELECT outer_field)" is
      substituted with "a_field = outer_field". As we moved the outer_field to the
      upper select it's not really outer anymore. But it was left marked as outer.
      If exists an index over a_field optimizer choose wrong execution plan and thus
      return wrong result.
      
      Now the Item_in_subselect::single_value_transformer function removes dependent
      marking from fields when a subselect is optimized away.

      Bug #45287: phase 1 : 32 bit compilation warnings · 45b687c0
      Georgi Kodinov authored
      Fixed the following problems:
      1. cmake 2.6 warning because of a changed default on
      how the dependencies to libraries with a specified 
      path are resolved.
      Fixed by requiring cmake 2.6.
      2. Removed an obsolete pre-NT4 hack including defining
      Windows system defines to alter the behavior of windows.h.
      3. Disabled warning C4065 on compiling sql_yacc.cc because
      of a know incompatibility in some of the newer bison binaries.

      Bug#37740 Server crashes on execute statement with full text search and · c77b836a
      Anurag Shekhar authored
                match against.
      
      
      Server crashes when executing prepared statement with duplicating
      MATCH() function calls in SELECT and ORDER BY expressions, e.g.:
      SELECT MATCH(a) AGAINST('test') FROM t1 ORDER BY MATCH(a) AGAINST('test')
      
      This query gets optimized by the server, so the value returned
      by MATCH() from the SELECT list is reused for ORDER BY purposes.
      To make this optimization server is comparing items from
      SELECT and ORDER BY lists. We were getting server crash because
      comparision function for MATCH() item is not intended to be called
      at this point of execution.
      
      In 5.0 and 5.1 this problem is workarounded by resetting MATCH()
      item to the state as it was during PREPARE.
      
      In 6.0 correct comparision function will be implemented and
      duplicating MATCH() items from the ORDER BY list will be
      optimized.

        Updated with the test case for Bug#37740
      mysql-test/t/fulltext.test:
        A test case for Bug#37740.
      sql/item_func.h:
        True initialization of 'table' happens in ::fix_fields(). As
        Item_func_match::eq() may be called before ::fix_fields(), it is
        expected that 'table' is initialized to 0 when it is reused.
        
        This is mostly affecting prepared statements, when the same item
        doesn't get destroyed, but rather cleaned up and reused.

      Bug #40113: Embedded SELECT inside UPDATE or DELETE can timeout · 410e1a72
      Georgi Kodinov authored
      without error
      
      When using quick access methods for searching rows in UPDATE or 
      DELETE there was no check if a fatal error was not already sent 
      to the client while evaluating the quick condition.
      As a result a false OK (following the error) was sent to the 
      client and the error was thus transformed into a warning.
      
      Fixed by checking for errors sent to the client during 
      SQL_SELECT::check_quick() and treating them as real errors.
      
      Fixed a wrong test case in group_min_max.test
      Fixed a wrong return code in mysql_update() and mysql_delete()

      Bug #45790 Potential DoS vector: Writing of user input to log · 3cd431d5
      Staale Smedseng authored
      without proper formatting
            
      The problem is that a suitably crafted database identifier
      supplied to COM_CREATE_DB or COM_DROP_DB can cause a SIGSEGV,
      and thereby a denial of service. The database name is printed
      to the log without using a format string, so potential
      attackers can control the behavior of my_b_vprintf() by
      supplying their own format string. A CREATE or DROP privilege
      would be required.
            
      This patch supplies a format string to the printing of the
      database name. A test case is added to mysql_client_test.
      
      
      sql/sql_parse.cc:
        Added format strings.
      tests/mysql_client_test.c:
        Added new test case.
