Subject: Bug#17711: DELETE doesn't use index when ORDER BY, LIMIT and
 non-restricting WHERE is present.

If a DELETE statement with ORDER BY and LIMIT contains a WHERE clause
with conditions that for sure cannot be used for index access (like in
WHERE @var:= field) the execution always follows the filesort path.
It happens currently even when for the above case there is an index that
can be used to speedup sorting by the order by list.

Now if a DELETE statement with ORDER BY and LIMIT contains such WHERE
clause conditions that cannot be used to build any quick select then
the mysql_delete() tries to use an index like there is no WHERE clause at all.

Subject: Bug#23409: Arguments of the ENCODE() and the DECODE() functions were
 not printed correctly.

The Item_func::print method was used to print the Item_func_encode and the
Item_func_decode objects. The last argument to ENCODE and DECODE functions
is a plain C string and thus Item_func::print wasn't able to print it.

The print() method is added to the Item_func_encode class. It correctly
prints the Item_func_encode and the Item_func_decode objects.

Subject: Bug#23417: Too strict checks against GROUP BY in the
 ONLY_FULL_GROUP_BY mode.

Currently in the ONLY_FULL_GROUP_BY mode no hidden fields are allowed in the
select list. To ensure this each expression in the select list is checked
to be a constant, an aggregate function or to occur in the GROUP BY list.
The last two requirements are wrong and doesn't allow valid expressions like
"MAX(b) - MIN(b)" or "a + 1" in a query with grouping by a.

The correct check implemented by the patch will ensure that:
any field reference in the [sub]expressions of the select list
  is under an aggregate function or
  is mentioned as member of the group list or
  is an outer reference or
  is part of the select list element that coincide with a grouping element.

The Item_field objects now can contain the position of the select list
expression which they belong to. The position is saved during the
field's Item_field::fix_fields() call.

The non_agg_fields list for non-aggregated fields is added to the SELECT_LEX
class. The SELECT_LEX::cur_pos_in_select_list now contains the position in the
select list of the expression being currently fixed.

Subject: Fixed bug #25398: crash in a trigger when using trigger fields in a
 select list. The objects of the Item_trigger_field class inherited the
 implementations of the methods copy_or_same, get_tmp_table_item and
 get_tmp_table_field from the class Item_field while they rather should have
 used the default implementations defined for the base class Item. It could
 cause catastrophic problems for triggers that used SELECTs with select list
 containing trigger fields such as NEW.<table column> under DISTINCT.

Subject: Fixed bug #24776: an assertion abort in handler::ha_index_init for
 queries using 'range checked for each record'. The problem was fixed in 5.0
 by the patch for bug 12291. This patch down-ported the corresponding code
 from 5.0 into QUICK_SELECT::init() and added a new test case.

Subject: BUG#20420: optimizer reports wrong keys on left join with IN  The
 optimizer needs to evaluate whether predicates are better  evaluated using an
 index. IN is one such predicate.  To qualify an IN predicate must involve a
 field of the index  on the left and constant arguments on the right.  However
 whether an expression is a constant can be determined only  by knowing the
 preceding tables in the join order.  Assuming that only IN predicates with
 expressions on the right that  are constant for the whole query qualify
 limits the scope of  possible optimizations of the IN predicate (more
 specifically it  doesn't allow the "Range checked for each record"
 optimization for  such an IN predicate.  Fixed by not pre-determining the
 optimizability of the IN predicate  in the case when all right IN operands
 are not SQL constant expressions

Subject: Fixed bug #25580: incorrect stored representations of views in cases
 when they contain the '!' operator. Added an implementation for the method
 Item_func_not::print. The method encloses any NOT expression into extra
 parentheses to avoid incorrect stored representations of views that use the
 '!' operators. Without this change when a view was created that contained the
 expression !0*5  its stored representation contained not this expression but
 rather the expression not(0)*5 . The operator '!' is of a higher precedence
 than '*', while NOT is of a lower precedence than '*'. That's why the
 expression !0*5 is interpreted as not(0)*5, while the expression not(0)*5 is
 interpreted as not((0)*5) unless sql_mode is set to HIGH_NOT_PRECEDENCE. Now
 we translate !0*5 into (not(0))*5.

Subject: Bug #25382: Passing NULL to an UDF called from stored procedures 
 crashes server  Check for null value is reliable only after calling some of
 the  val_xxx() methods. If the val_xxx() method is not called  the null_value
 flag will be set only for certain types of NULL  values (like SQL constant
 NULLs for example).  This caused a crash while trying to dereference a NULL
 pointer  that is returned by val_str() for NULL values.  Fixed by swapping
 the order of val_xxx() and null_value check.

Subject: Bug#25172: Not checked buffer size leads to a server crash.

After fix for bug#21798 JOIN stores the pointer to the buffer for sorting
fields. It is used while sorting for grouping and for ordering. If ORDER BY
clause has more elements then the GROUP BY clause then a memory overrun occurs.

Now the length of the ORDER BY list is always passed to the
make_unireg_sortorder() function and it allocates buffer big enough to be
used for bigger list.

Subject: Bug#25123: ON DUPLICATE KEY clause allows fields not from the insert
 table.

When inserting into a join-based view the update fields from the ON DUPLICATE
KEY UPDATE wasn't checked to be from the table being inserted into and were
silently ignored.

The new check_view_single_update() function is added to check that
insert/update fields are being from the same single table of the view.
