Now we don't take any mutexes when creating or dropping internal HEAP tables during SELECT.
Change buffer sizes to size_t to make keycache 64 bit safe on platforms where sizeof(ulong) != sizeof(size_t)
BitKeeper/etc/ignore:
added support-files/mysqld_multi.server
include/heap.h:
Added 'internal_table' to HP_CREATE_INFO
include/keycache.h:
Change buffer sizes to size_t to make keycache 64 bit safe
include/my_base.h:

mysys/mf_keycache.c:
Change buffer sizes to size_t to make keycache 64 bit safe
sql/sql_select.cc:
Added HA_OPEN_INTERNAL_TABLE to mark temporary tables that should be deleted on close
Removed not anymore needed call to delete_table()
storage/heap/ha_heap.cc:
Added support for internal temporary tables that should be deleted on close.
Internal tables now use dedicated open and close calls to avoid taking mutexes.
If heap_open() failes, now delete the newly created table. (This fixes a possible memory leak)
Remove never executed info() in create()
storage/heap/ha_heap.h:
Added slots needed to handle internal temporary tables
storage/heap/heapdef.h:
Protect against C++ inclusion
storage/heap/hp_close.c:
Don't call list_delete() for internal temporary tables (They are not in the list)
storage/heap/hp_create.c:
Added HP_SHARE ** element to heap_create() to store the SHARE of the newly created table.
For internal temporary tables: Don't take any mutex and don't put them into the open table list.
storage/heap/hp_open.c:
Split heap_open() into sub functions to be able to create internal temporary tables without putting them in the heap_share_list.
Add faster open() functions for when we already know the 'share'.
storage/heap/hp_test1.c:
Update call to heap_create()
Initialize all keyinfo members.
storage/heap/hp_test2.c:
Update call to heap_create()
Now we don't take any mutexes when creating or dropping internal HEAP tables during SELECT.
Change buffer sizes to size_t to make keycache 64 bit safe on platforms where sizeof(ulong) != sizeof(size_t)

This bug manifested itself for join queries with GROUP BY and HAVING clauses
whose SELECT lists contained DISTINCT. It occurred when the optimizer could
deduce that the result set would have not more than one row.
The bug could lead to wrong result sets for queries of this type because
HAVING conditions were erroneously ignored in some cases in the function
remove_duplicates.

ORDER BY primary_key on InnoDB table
Queries that use an InnoDB secondary index to retrieve
data don't need to sort in case of ORDER BY primary key
if the secondary index is compared to constant(s).
They can also skip sorting if ORDER BY contains both the
the secondary key parts and the primary key parts (in
that order).
This is because InnoDB returns the rows in order of the
primary key for rows with the same values of the secondary
key columns.
Fixed by preventing temp table sort for the qualifying
queries.

A bug in the restore_prev_nj_state function allowed interleaving
inner tables of outer join operations with outer tables. With the
current implementation of the nested loops algorithm it could lead
to wrong result sets for queries with nested outer joins.
Another bug in this procedure effectively blocked evaluation of some

The need arose when working on Bug 26141, where it became
necessary to replace TABLE_LIST with its forward declaration in a few
headers, and this involved a lot of s/TABLE_LIST/st_table_list/.
Although other workarounds exist, this patch is in line
with our general strategy of moving away from typedef-ed names.
Sometime in future we might also rename TABLE_LIST to follow the
coding style, but this is a huge change.

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.

the loose scan optimization for grouping queries was applied returned
a wrong result set when the query was used with the SQL_BIG_RESULT
option.
The SQL_BIG_RESULT option forces to use sorting algorithm for grouping
queries instead of employing a suitable index. The current loose scan
optimization is applied only for one table queries when the suitable
index is covering. It does not make sense to use sort algorithm in this
case. However the create_sort_index function does not take into account
the possible choice of the loose scan to implement the DISTINCT operator
which makes sorting unnecessary. Moreover the current implementation of
the loose scan for queries with distinct assumes that sorting will
never happen. Thus in this case create_sort_index should not call
the function filesort.

Added a test case for bug #25602.
mysql-test/t/group_min_max.test:
Added a test case for bug #25602.
the loose scan optimization for grouping queries was applied returned
a wrong result set when the query was used with the SQL_BIG_RESULT
option.
The SQL_BIG_RESULT option forces to use sorting algorithm for grouping
queries instead of employing a suitable index. The current loose scan
optimization is applied only for one table queries when the suitable
index is covering. It does not make sense to use sort algorithm in this
case. However the create_sort_index function does not take into account
the possible choice of the loose scan to implement the DISTINCT operator
which makes sorting unnecessary. Moreover the current implementation of
the loose scan for queries with distinct assumes that sorting will
never happen. Thus in this case create_sort_index should not call
the function filesort.
