e7c6a81f25 Fixed bug #28076: inconsistent binary/varbinary comparison.
After adding an index the <VARBINARY> IN (SELECT <BINARY> ...)
clause returned a wrong result: the VARBINARY value was illegally padded
with zero bytes to the length of the BINARY column for the index search.
(<VARBINARY>, ...) IN (SELECT <BINARY>, ... ) clauses are affected too.


sql/item.cc:
  Fixed bug #28076.
  The Item_cache_str::save_in_field method has been overloaded
  to check cached values for an illegal padding before the saving
  into a field.
sql/item.h:
  Fixed bug #28076.
  The Item_cache_str::is_varbinary flag has been added and the
  Item_cache_str::save_in_field method has been overloaded to prevent
  cached values from an illegal padding when saving in fields.
  The signature of the Item_cache::get_cache method has been
  changed to accept pointers to Item instead of Item_result
  values.
sql/item_cmpfunc.cc:
  Fixed bug #28076.
  The Item_in_optimizer::fix_left method has been modified to
  to call Item_cache::get_cache in a new manner.
sql/item_subselect.cc:
  Fixed bug #28076.
  The subselect_indexsubquery_engine::exec method has been
  modified to take into account field conversion errors
  (copy&paste from subselect_uniquesubquery_engine::exec).
sql/sp_rcontext.cc:
  Fixed bug #28076.
  The sp_rcontext::create_case_expr_holder method has been
  modified to call Item_cache::get_cache in a new manner.
sql/sp_rcontext.h:
  Fixed bug #28076.
  The sp_rcontext::create_case_expr_holder method signature
  has been modified to pass Item pointers to the
  Item_cache::get_cache method.
sql/sql_class.cc:
  Fixed bug #28076.
  The select_max_min_finder_subselect::send_data method has been
  modified to call Item_cache::get_cache in a new manner.

6bbdacae20 Bug #31884: Assertion + crash in subquery in the SELECT clause.
Item_in_subselect's only externally callable method is val_bool().
However the nullability in the wrapper class (Item_in_optimizer) is 
established by calling the "forbidden" method val_int().

Fixed to use the correct method (val_bool() ) to establish nullability 
of Item_in_subselect in Item_in_optimizer.

c2e961cf2e Bug#27333: subquery grouped for aggregate of outer
query / no aggregate of subquery
 The optimizer counts the aggregate functions that 
 appear as top level expressions (in all_fields) in 
 the current subquery. Later it makes a list of these
 that it uses to actually execute the aggregates in
 end_send_group().
 That count is used in several places as a flag whether
 there are aggregates functions.
 While collecting the above info it must not consider
 aggregates that are not aggregated in the current 
 context. It must treat them as normal expressions 
 instead. Not doing that leads to incorrect data about
 the query, e.g. running a query that actually has no
 aggregate functions as if it has some (and hence is
 expected to return only one row).
 Fixed by ignoring the aggregates that are not aggregated
 in the current context. 
 One other smaller omission discovered and fixed in the 
 process : the place of aggregation was not calculated for
 user defined functions. Fixed by calling 
 Item_sum::init_sum_func_check() and 
 Item_sum::check_sum_func() as it's done for the rest of 
 the aggregate functions.

d8e2f2622d Fixed bug #28811: crash for a query containing a subquery with
ORDER BY and LIMIT 1. 
The bug was introduced by the patch for bug 21727. The patch
erroneously skipped initialization of the array of headers
for sorted records for non-first evaluations of the subquery.

To fix the problem a new parameter has been added to the
function make_char_array that performs the initialization.
Now this function is called for any invocation of the 
filesort procedure. Yet it allocates the buffer for sorted
records only if this parameter is NULL.

8c4ff24b56 Fixed bug #28728: a crash when executing EXPLAIN EXTENDED for a query
using a derived table over a grouping subselect.

This crash happens only when materialization of the derived tables 
requires creation of auxiliary temporary table, for example when
a grouping operation is carried out with usage of a temporary table.

The crash happened because EXPLAIN EXTENDED when printing the query
expression made an attempt to use the objects created in the mem_root
of the temporary table which has been already freed by the moment
when printing is called.

This bug appeared after the method Item_field::print() had been 
introduced.

  Fixed bug #28337: wrong results for grouping queries with correlated
  subqueries in WHERE conditions.
  This bug was introduced by the patch for bug 27321.
  
  Now in the Item_field::fix_outer_field function we create an Item_outer_ref
  object for an outer reference only if it is used in the SELECT list or
  in the HAVING clause of the subquery against which the reference is resolved.

0ad4e1b2a6 Bug #27807.
Non-correlated scalar subqueries may get executed
in EXPLAIN at the optimization phase if they are
part of a right hand sargable expression.
If the scalar subquery uses a temp table to 
materialize its results it will replace the 
subquery structure from the parser with a simple
select from the materialization table.
As a result the EXPLAIN will crash as the 
temporary materialization table is not to be shown
in EXPLAIN at all.
Fixed by preserving the original query structure
right after calling optimize() for scalar subqueries
with temp tables executed during EXPLAIN.

e14fd2b651 Bug #27363:
Validity checks for nested set functions
were not taking into account that the enclosed
set function may be on a nest level that is
lower than the nest level of the enclosing set
function.
Fixed by :
 - propagating max_sum_func_level
up the enclosing set functions chain.
 - updating the max_sum_func_level of the 
   enclosing set function when the enclosed set
   function is aggregated above or on the same
   nest level of as the level of the enclosing 
   set function.
 - updating the max_arg_level of the enclosing
   set function on a reference that refers to
   an item above or on the same nest level
   as the level of the enclosing set function.
 - Treating both Item_field and Item_ref as possibly
   referencing items from outer nest levels.

1cf3b96513 Bug#27321: Wrong subquery result in a grouping select.
The Item_outer_ref class based on the Item_direct_ref class was always used
to represent an outer field. But if the outer select is a grouping one and the 
outer field isn't under an aggregate function which is aggregated in that
outer select an Item_ref object should be used to represent such a field.
If the outer select in which the outer field is resolved isn't grouping then
the Item_field class should be used to represent such a field.
This logic also should be used for an outer field resolved through its alias
name.

Now the Item_field::fix_outer_field() uses Item_outer_field objects to
represent aliased and non-aliased outer fields for grouping outer selects
only.
Now the fix_inner_refs() function chooses which class to use to access outer
field - the Item_ref or the Item_direct_ref. An object of the chosen class
substitutes the original field in the Item_outer_ref object.
The direct_ref and the found_in_select_list fields were added to the
Item_outer_ref class.

If a set function with a outer reference s(outer_ref) cannot be aggregated 
the outer query against which the reference has been resolved then MySQL
interpretes s(outer_ref) in the same way as it would interpret s(const).
Hovever the standard requires throwing an error in this situation.
Added some code to support this requirement in ansi mode.
Corrected another minor bug in Item_sum::check_sum_func.

when the column is to be read from a derived table column which 
was specified as a concatenation of string literals.
The bug happened because the Item_string::append did not adjust the

a1e20e04d8 Bug#21904 (parser problem when using IN with a double "(())")
Before this fix, a IN predicate of the form: "IN (( subselect ))", with two
parenthesis, would be evaluated as a single row subselect: if the subselect
returns more that 1 row, the statement would fail.

The SQL:2003 standard defines a special exception in the specification,
and mandates that this particular form of IN predicate shall be equivalent
to "IN ( subselect )", which involves a table subquery and works with more
than 1 row.

This fix implements "IN (( subselect ))", "IN ((( subselect )))" etc
as per the SQL:2003 requirement.

All the details related to the implementation of this change have been
commented in the code, and the relevant sections of the SQL:2003 spec
are given for reference, so they are not repeated here.

Having access to the spec is a requirement to review in depth this patch.

da561a802c Fixed bug #24653.
The bug report has demonstrated the following two problems.
1. If an ORDER/GROUP BY list includes a constant expression being 
optimized away and, at the same time, containing single-row
subselects that return more that one row, no error is reported.
Strictly speaking the standard allows to ignore error in this case.
Yet, now a corresponding fatal error is reported in this case.
2. If a query requires sorting by expressions containing single-row
subselects that, however, return more than one row, then the execution
of the query may cause a server crash. 
To fix this some code has been added that blocks execution of a subselect
item in case of a fatal error in the method Item_subselect::exec.

edf72bf613 Fixed bug #25219: crash for a query that contains an EXIST subquery with
UNION over correlated and uncorrelated SELECTS.
In such subqueries each uncorrelated SELECT should be considered as
uncacheable. Otherwise join_free is called for it and in many cases
it causes some problems.
