  The Field_set::store(longlong nr,...) method incompletely
  calculates a bit mask for the comparison with a given number:
  if that number is greater than 0x7F00 0000 0000 0000 (LONGLONG_MAX),
  it uses zero bit mask instead of 0xFFFF FFFF FFFF FFFF (ULONGLONG_MAX).
  
  Incomplete expression has been replaced with a set_bits macro call.

The bug was that handler::clone/handler::ha_open() call caused allocation of 
cloned_copy->ref on the handler->table->mem_root. The allocated memory could not 
be reclaimed until the table is flushed, so it was possible to exhaust memory by 
repeatedly running index_merge queries without doing table flushes.  

The fix:
- make handler::clone() allocate new_handler->ref on the passed mem_root 
- make handler::ha_open() not allocate this->ref if it has already been allocated
There is no testcase as it is not possible to check small leaks from testsuite.

Server handles truncation for assignment of too-long values
into CHAR/VARCHAR/TEXT columns in a different ways when the
truncated characters are spaces:
1. CHAR(N) columns silently ignore end-space truncation;
2. TEXT columns post a truncation warning/error in the
   non-strict/strict mode.
3. VARCHAR columns always post a truncation note in
   any mode.

Space truncation processing has been synchronised over
CHAR/VARCHAR/TEXT columns: current behavior of VARCHAR
columns has been propagated as standard.

Binary-encoded string/BLOB columns are not affected.

                    on table creates

The problem was in incompatible syntax for key definition in CREATE
TABLE.

5.0 supports only the following syntax for key definition (see "CREATE
TABLE syntax" in the manual):

{INDEX|KEY} [index_name] [index_type] (index_col_name,...)

While 5.1 parser supports the above syntax, the "preferred" syntax was
changed to:

{INDEX|KEY} [index_name] (index_col_name,...) [index_type]

The above syntax is used in 5.1 for the SHOW CREATE TABLE output, which
led to dumps generated by 5.1 being incompatible with 5.0.

Fixed by changing the parser in 5.0 to support both 5.0 and 5.1 syntax
for key definition.

Simple subselects are pulled into upper selects. This operation substitutes the
pulled subselect for the first item from the select list of the subselect.
If an alias is defined for a subselect it is inherited by the replacement item.
As this is done after fix_fields phase this alias isn't showed if the
replacement item is a stored function. This happens because the Item_func_sp::make_field
function makes send field from its result_field and ignores the defined alias.

Now when an alias is defined the Item_func_sp::make_field function sets it for
the returned field.

Two disjuncts containing equalities of the form key=const1 and key=const2 can
be merged into one if const1 is equal to const2. To check it the common 
collation of the constants were used rather than the collation of the field key.
For example when the default collation of the constants was cases insensitive
while the collation of the field was case sensitive, then two or-ed equality 
predicates key='b' and key='B' incorrectly were merged into one f='b'. As a 
result ref access was used instead of range access and wrong result sets were 
returned in many cases. 
Fixed the problem by comparing constant in the or-ed predicate with collation of
the key field.

value when inserting into a view.

The mysql_prepare_insert function checks all fields of the target table that
directly or indirectly (through a view) are specified in the INSERT
statement to have a default value. This check can be skipped if the INSERT
statement doesn't mention any insert fields. In case of a view this allows
fields that aren't mentioned in the view to bypass the check.

Now fields of the target table are always checked to have a default value
when insert goes into a view.

server crash.

The filesort implementation has an optimization for subquery execution which
consists of reusing previously allocated buffers. In particular the call to
the read_buffpek_from_file function might be skipped when a big enough buffer
for buffer descriptors (buffpeks) is already allocated. Beside allocating
memory for buffpeks this function fills allocated buffer with data read from
disk. Skipping it might led to using an arbitrary memory as fields' data and
finally to a crash.

Now the read_buffpek_from_file function is always called. It allocates
new buffer only when necessary, but always fill it with correct data.
