94507ee756 Fixed bug #28716.
The result of the CHECK OPTION condition evaluation over an
updated record and records of merged tables was arbitrary and
dependant on the order of records in the merged tables during
the execution of SELECT statement.

The CHECK OPTION expression was evaluated over expired record
buffers (with arbitrary data in the fields).

Rowids of tables used in the CHECK OPTION expression were
added to temporary table rows. The multi_update::do_updates()
method was modified to restore necessary record buffers
before evaluation of the CHECK OPTION condition.

4e9cef545c Bug #28492: subselect returns LONG in >5.0.24a and LONGLONG in <=5.0.24a
Integer values with 10 digits may or may not fit into an int column 
(e.g. 2147483647 vs 6147483647).
Thus when creating a temp table column for such an int we must
use bigint instead.
Fixed to use bigint.
Also subsituted a "magic number" with a named constant.

d393c9e666 Bug#28450: The Item_date_add_interval in select list may fail the field
type assertion.

The bug was introduced by the patch for bug #16377.
The "+ INTERVAL" (Item_date_add_interval) function detects its result type
by the type of its first argument. But in some cases it returns STRING
as the result type. This happens when, for example, the first argument is a 
DATE represented as string. All this makes the get_datetime_value()
function misinterpret such result and return wrong DATE/DATETIME value.
To avoid such cases in the fix for #16377 the code that detects correct result
field type on the first execution was added to the
Item_date_add_interval::get_date() function. Due to this the result
field type of the Item_date_add_interval item stored by the send_fields()
function differs from item's result field type at the moment when
the item is actually sent. It causes an assertion failure.

Now the get_datetime_value() detects that the DATE value is returned by
some item not only by checking the result field type but also by comparing
the returned value with the 100000000L constant - any DATE value should be
less than this value.
Removed result field type adjusting code from the
Item_date_add_interval::get_date() function.

9e06efb45c Bug #28605: SHOW CREATE VIEW with views using stored_procedures no
longer showing SP names.
SHOW CREATE VIEW uses Item::print() methods to reconstruct the 
statement text from the parse tree.
The print() method for stored procedure calls needs allocate 
space to print the function's quoted name.
It was incorrectly calculating the length of the buffer needed 
(was too short).

  Setting the value of join->tables to for a subquery created serious

  after a call of the JOIN::join_free method.
  In fact setting join->tables to 0 in JOIN::cleanup is not needed 
  anywhere in the current code.

1734b4e990 Bug#27563: Stored functions and triggers wasn't throwing an error when killed.
If a stored function or a trigger was killed it had aborted but no error
was thrown. This allows the caller statement to continue without a notice.
This may lead to a wrong data being inserted/updated to/deleted as in such
cases the correct result of a stored function isn't guaranteed. In the case
of triggers it allows the caller statement to ignore kill signal and to
waste time because of re-evaluation of triggers that always will fail
because thd->killed flag is still on.

Now the Item_func_sp::execute() and the sp_head::execute_trigger() functions
check whether a function or a trigger were killed during execution and
throws an appropriate error if so.
Now the fill_record() function stops filling record if an error was reported
through thd->net.report_error.

f3b78f34e5 Bug#27507: Wrong DATETIME value was allowed by ALTER TABLE in the NO_ZERO_DATE
mode.

When a new DATE/DATETIME field without default value is being added by the
ALTER TABLE the '0000-00-00' value is used as the default one. But it wasn't
checked whether such value was allowed by the set sql mode. Due to this
'0000-00-00' values was allowed for DATE/DATETIME fields even in the
NO_ZERO_DATE mode.

Now the mysql_alter_table() function checks whether the '0000-00-00' value
is allowed for DATE/DATETIME fields by the set sql mode.
The new error_if_not_empty flag is used in the mysql_alter_table() function
to indicate that it should abort if the table being altered isn't empty.
The new new_datetime_field field is used in the mysql_alter_table() function
for error throwing purposes. 
The new error_if_not_empty parameter is added to the copy_data_between_tables()
function to indicate the it should return error if the source table isn't empty.
