89d2b8efb9 Bug#34773: query with explain extended and derived table / other table
crashes server

When creating temporary table that contains aggregate functions a 
non-reversible source transformation was performed to redirect aggregate
function arguments towards temporary table columns.
This caused EXPLAIN EXTENDED to fail because it was trying to resolve
references to the (freed) temporary table.
Fixed by preserving the original aggregate function arguments and
using them (instead of the transformed ones) for EXPLAIN EXTENDED.

1a68ec2809 Fix for bug #35298: GROUP_CONCAT with DISTINCT can crash the server
The bug is a regression introduced by the patch for bug32798.

The code in Item_func_group_concat::clear() relied on the 'distinct'
variable to check if 'unique_filter' was initialized. That, however,
is not always valid because Item_func_group_concat::setup() can do
shortcuts in some cases w/o initializing 'unique_filter'.

Fixed by checking the value of 'unique_filter' instead of 'distinct'
before dereferencing.


mysql-test/r/func_gconcat.result:
  Added test cases for bugs #35298 and #36024.

  of distinct does not always mean that unique_filter is initialized
  because Item_func_group_concat::setup() can do shortcuts is some cases

9d661efd7f Bug#27219: Aggregate functions in ORDER BY.
Mixing aggregate functions and non-grouping columns is not allowed in the
ONLY_FULL_GROUP_BY mode. However in some cases the error wasn't thrown because
of insufficient check.

In order to check more thoroughly the new algorithm employs a list of outer
fields used in a sum function and a SELECT_LEX::full_group_by_flag.
Each non-outer field checked to find out whether it's aggregated or not and
the current select is marked accordingly.
All outer fields that are used under an aggregate function are added to the
Item_sum::outer_fields list and later checked by the Item_sum::check_sum_func
function.

8270d9875f Fix for bug #34512: CAST( AVG( double ) AS DECIMAL )
returns wrong results

Casting AVG() to DECIMAL led to incorrect results when the arguments
had a non-DECIMAL type, because in this case
Item_sum_avg::val_decimal() performed the division by the number of
arguments twice.

Fixed by changing Item_sum_avg::val_decimal() to not rely on
Item_sum_sum::val_decimal(), i.e. calculate sum and divide using
DECIMAL arithmetics for DECIMAL arguments, and utilize val_real() with
subsequent conversion to DECIMAL otherwise.

sql/item_sum.cc:
  Do not use Item_sum_sum::val_decimal() in Item_sum_avg::val_decimal()
  because the first one, depending on the arguments type, may return
  either the sum of the arguments, or the average calculated by the
  virtual val_real() method of Item_sum_avg. Instead, do our own
  calculation based on the arguments type.

a3e83048a3 Fix for Bug#30217: Views: changes in metadata behaviour
between 5.0 and 5.1.
  
The problem was that in the patch for Bug#11986 it was decided
to store original query in UTF8 encoding for the INFORMATION_SCHEMA.
This approach however turned out to be quite difficult to implement
properly. The main problem is to preserve the same IS-output after
dump/restore.
  
So, the fix is to rollback to the previous functionality, but also
to fix it to support multi-character-set-queries properly. The idea
is to generate INFORMATION_SCHEMA-query from the item-tree after
parsing view declaration. The IS-query should:
  - be completely in UTF8;
  - not contain character set introducers.
  
For more information, see WL4052.

012aab7d8b Fix for bug #33049: Assert while running test-as3ap test(mysql-bench
suite)

Under some circumstances a combination of aggregate functions and
GROUP BY in a SELECT query over a VIEW could lead to incorrect
calculation of the result type of the aggregate function. This in
turn could result in incorrect results, or assertion failures on debug
builds.

Fixed by changing the logic in Item_sum_hybrid::fix_fields() so that
the argument's item is dereferenced before calling its type() method.

0fbc29c197 A pre-requisite for the fix for Bug#12713 "Error in a stored function

Make private all class handler methods (PSEA API) that may modify
data. Introduce and deploy public ha_* wrappers for these methods in 
all sql/.
This necessary to keep track of all data modifications in sql/,
which is in turn necessary to be able to optimize two-phase
commit of those transactions that do not modify data.


sql/ha_partition.cc:
  Class ha_partition is no longer a friend of class handler.
  Use the public handler interface (handler::ha_ methods) for partition
  operations.

sql/handler.cc:
  Function ha_create_table() is no longer a friend of class handler.
  Use public handler::change_table_ptr() to access private members.
  This fixes a subtle bug (no test case in the test suite) when a
  deletion error occurs inside one partition of a partitioned engine. 
  The old code would crash in handler::print_error() in this case.
  
  Implement the newly introduced public ha_* wrappers of the private
  virtual handler methods.
sql/handler.h:
  Introduce ha_* wrappers to all class handler methods that may

0c4b3f5784 Bug#32798: DISTINCT in GROUP_CONCAT clause fails when ordering by a column
with null values

For queries containing GROUP_CONCAT(DISTINCT fields ORDER BY fields), there 
was a limitation that the DISTINCT fields had to be the same as ORDER BY 
fields, owing to the fact that one single sorted tree was used for keeping 
track of tuples, ordering and uniqueness. Fixed by introducing a second 
structure to handle uniqueness so that the original structure has only to 
order the result.

24a567e9f6 Fix for bug #31154: field.h:1649: virtual int Field_bit::cmp(const uchar*, const uchar*): Assertion
Problem: GROUP_CONCAT(DISTINCT BIT_FIELD...) uses a tree to store keys;
which are constructed using a temporary table fields,
see Item_func_group_concat::setup().
As a) we don't store null bits in the tree where the bit fields store parts 
of their data and b) there's no method to properly compare two table records
we've got problem.

Fix: convert BIT fields to INT in the temporary table used.

There was an assertion to detect a bug in ROLLUP

- The fix is to make COUNT(DISTINCT ...) code instruct create_tmp_table to

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.
