Treat queries with no FROM and aggregate functions as normal queries,
so the aggregate function get correctly calculated as if there is 1 row. 
This means that they will be considered to have one row, so COUNT(*) will return
1 instead of 0. Other aggregates will behave in compatible manner.

When processing aggregate functions all tables values are reset
to NULLs at the end of each group. 
When doing that if there are no rows found for a group
the const tables must not be reset as they are not recalculated 
by do_select()/sub_select() for each group.

  * Bug #20792: Incorrect results from aggregate subquery
   - test suite for the bug. This is dependent on InnoDB despite
     the fact that the bug and the fix are not InnoDB specific.
     This is because of the table flag HA_NOT_EXACT_COUNT.
     When this flag is off (as in MyISAM) both t2 and t3 become of
     join type 'system' as they are estimated to have 1 record and
     and this statistics can be trusted (according to the absence of
     HA_NOT_EXACT_COUNT).

Too many cursors (more than 1024) could lead to memory corruption.
This affects both, stored routines and C API cursors, and the
threshold is per-server, not per-connection.  Similarly, the
corruption could happen when the server was under heavy load
(executing more than 1024 simultaneous complex queries), and this is
the reason why this bug is fixed in 4.1, which doesn't support
cursors.

The corruption was caused by a bug in the temporary tables code, when
an attempt to create a table could lead to a write beyond allocated
space.  Note, that only internal tables were affected (the tables
created internally by the server to resolve the query), not tables
created with CREATE TEMPORARY TABLE.  Another pre-condition for the
bug is TRUE value of --temp-pool startup option, which, however, is a
default.

The cause of a bug was that random memory was overwritten in
bitmap_set_next() due to out-of-bound memory access.


mysys/my_bitmap.c:
  Local 'bitmap_size' is measured in bytes, no need to multiply it by 8.
sql/sql_select.cc:
  Clear the temp_pool_slot bit only if we have set it previously.

 When optimizing conditions like 'a = <some_val> OR a IS NULL' so that they're
 united into a single condition on the key and checked together the server must 
 check which value is the NULL value in a correct way : not only using ->is_null 
 but also check if the expression doesn't depend on any tables referenced in the 
 current statement. 
 This additional check must be performed because that optimization takes place 
 before the actual execution of the statement, so if the field was initialized 
 to NULL from a previous statement the optimization would be applied incorrectly.

The problem was in that opt_sum_query() replaced MIN/MAX functions
with the corresponding constant found in a key, but due to imprecise
representation of float numbers, when evaluating the where clause,
this comparison failed.

When MIN/MAX optimization detects that all tables can be removed,
also remove all conjuncts in a where clause that refer to these
tables. As a result of this fix, these conditions are not evaluated
twice, and in the case of float number comparisons we do not discard
result rows due to imprecise float representation.

As a side-effect this fix also corrects an unnoticed problem in
bug 12882.


mysql-test/r/func_group.result:
  BUG#20954 - test result adjustment.
  Adjusted the test result of bug 12882 which was not preperly fixed.
  The current patch corrects the problem that was fully corrected by the
  patch for 12882.
  
  The problem was that opt_sum_query() indicated that the optimizer may
  remove all tables because all MIN/MAX/COUNT functions are constants,
  but this lead to an empty result instead of NULL because the WHERE
  clause was still evaluated.
  
  The current fix removes all conjuncts in the where clause that
  reference the removed tables, and thus corrects the problem.

for class Item_func_trim. 
For 4.1 it caused wrong output for EXPLAIN EXTENDED commands
if expressions with the TRIM function of two arguments were used.
For 5.0 it caused an error message when trying to select
from a view with the TRIM function of two arguments.
This unexpected error message was due to the fact that the
print method for the class Item_func_trim was inherited from
the class Item_func. Yet the TRIM function does not take a list
of its arguments. Rather it takes the arguments in the form:
  [{BOTH | LEADING | TRAILING} [remstr] FROM] str) |
  [remstr FROM] str

  function takes the arguments in the following forms:
