Sometimes a parameter slot may not get a value because of the protocol
data being plain wrong.
Such cases should be detected and handled by returning an error.
Fixed by checking data stream constraints where possible (like maximum
length) and reacting to the case where a value cannot be constructed.

Bug #28934:

When the INSERT .. ON DUPLICATE KEY UPDATE has to update a matched row but
the new data is the same as in the record then it returns as if
no rows were inserted or updated. Nevertheless the row is silently
updated. This leads to a situation when zero updated rows are reported
in the case when data has actually been changed.
Now the write_record function updates a row only if new data differs from
that in the record.

on PPC/Debian Linux default stack size for a thread is too big.

thread creation fails if we create lots of threads (as it
happens in flush.test). So now stack size is explicitly specified

When constructing the path to the original .frm file ALTER .. RENAME
was unnecessary (and incorrectly) lowercasing the whole path when not
on a case-insensitive filesystem.
This path should not be modified because of lower_case_table_names
as it is already in the correct case according to that setting.
Fixed by removing the lowercasing.
Unfortunately testing this would require running the tests on a case
sensitive filesystem in a directory that has uppercase letters.
This cannot be guaranteed in all setups so no test case added.

The bug was introduced by the patch for bug 21727. The patch
erroneously skipped initialization of the array of headers
for sorted records for non-first evaluations of the subquery.
To fix the problem a new parameter has been added to the
function make_char_array that performs the initialization.
Now this function is called for any invocation of the
filesort procedure. Yet it allocates the buffer for sorted
records only if this parameter is NULL.

This bug was introduced by the fix for the bug#27300. In this fix a section
of code was added to the Item::tmp_table_field_from_field_type method.
This section intended to create Field_geom fields for the Item_geometry_func
class and its descendants. In order to get the geometry type of the current
item it casted "this" to the Item_geometry_func* type. But the
Item::tmp_table_field_from_field_type method is also used for creation of
fields for UNION and in this case this method is called for an object of the
Item_type_holder class and the cast to the Item_geometry_func* type causes
a server crash.
Now the Item::tmp_table_field_from_field_type method correctly works when it's
called for both the Item_type_holder and the Item_geometry_func classes.
The new geometry_type variable is added to the Item_type_holder class.
The new method called get_geometry_type is added to the Item_field
and the Field classes. It returns geometry type from the field for the
Item_field and the Field_geom classes and fails an assert for other Field
descendants.
sql/field.h:

a temporary table has grown out of heap memory reserved for it and
the remaining disk space is not big enough to store the table as
a MyISAM table.
The crash happens because the function create_myisam_from_heap
does not handle safely the mem_root structure associated
with the converted table in the case when an error has occurred.

a special code has been added that raises an error for a newly

When making key reference buffers over CHAR fields whitespace (0x20)

flag is set.
When the CLIENT_FOUND_ROWS flag is set then the server should return
found number of rows independently whether they were updated or not.
But this wasn't the case for the INSERT statement which always returned
number of rows that were actually changed thus providing wrong info to
the user.
Now the select_insert::send_eof method and the mysql_insert function
are sending the number of touched rows if the CLIENT_FOUND_ROWS flag is set.

Added a test case for the bug#28505: mysql_affected_rows() may return wrong result

This bug is introduced by the fix for bug#16377. Before the fix the
Item_func_between::fix_length_and_dec method converted the second and third
arguments to the type of the first argument if they were constant and the first
argument is of the DATE/DATETIME type. That approach worked well for integer
constants and sometimes produced bad result for string constants. The fix for
the bug#16377 wrongly removed that code at all and as a result of this the
comparison of a DATETIME field and an integer constant was carried out in a
wrong way and sometimes led to wrong result sets.
Now the Item_func_between::fix_length_and_dec method converts the second and
third arguments to the type of the first argument if they are constant, the
first argument is of the DATE/DATETIME type and the DATETIME comparator isn't
applicable.

The value of "low-priority-updates" option and the LOW PRIORITY
prefix was taken into account at parse time.
This caused triggers (among others) to ignore this flag (if
supplied for the DML statement).
Moved reading of the LOW_PRIORITY flag at run time.
Fixed an incosistency when handling
SET GLOBAL LOW_PRIORITY_UPDATES : now it is in effect for
delayed INSERTs.
Tested by checking the effect of LOW_PRIORITY flag via a

sql/item_func.cc:
Post fix for bug#28494.
The Item_func_set_user_var::check method now silently doesn't use result_field
if it isn't defined.
This is an additional fix.
Item::val_xxx methods are supposed to use original data source and
Item::val_xxx_result methods to use the item's result field. But for the
Item_func_set_user_var class val_xxx_result methods were mapped to val_xxx
methods. This leads, in particular, to producing bad sort keys and thus
wrong order of the result set of queries with group by/order by clauses.
The set of val_xxx_result methods is added to the Item_func_set_user_var
class. It's the same as the val_xxx set of method but uses the result_field
to return a value.

using a derived table over a grouping subselect.
This crash happens only when materialization of the derived tables
requires creation of auxiliary temporary table, for example when
a grouping operation is carried out with usage of a temporary table.
The crash happened because EXPLAIN EXTENDED when printing the query
expression made an attempt to use the objects created in the mem_root
of the temporary table which has been already freed by the moment
when printing is called.
This bug appeared after the method Item_field::print() had been
introduced.
