mysqld crashed when a long-running explain query was killed from
another connection.
When the current thread caught a kill signal executing the function
best_extension_by_limited_search it just silently returned to
the calling function greedy_search without initializing elements of
the join->best_positions array.
However, the greedy_search function ignored thd->killed status
after a calls to the best_extension_by_limited_search function, and
after several calls the greedy_search function used an uninitialized
data from the join->best_positions[idx] to search position in the
join->best_ref array.
That search failed, and greedy_search tried to call swap_variables
function with NULL argument - that caused a crash.
sql/sql_select.cc:
Fixed bug #28598.
choose_plan(), greedy_search(), best_extension_by_limited_search()
and find_best() functions have been changed to return TRUE in case
of fatal error.

ENUM fields internally store their values as integers and may use integer
values as indexes to their values. Invalid values are mapped to zero value.
When storing an empty string the ENUM field fails to find an appropriate value
and tries to convert the provided string to integer. The conversion also
fails and error is returned even if the thd->count_cuted_fields is set to
CHECK_FIELD_IGNORE. This makes the range optimizer wrongly decide that an
impossible range is present.
Now the Field_enum::store() returns error while storing an empty string only
if the thd->count_cuted_fields isn't set to CHECK_FIELD_IGNORE.

Problem: Unicode->UJIS followed incorrect conversion
rules for U+00A5 YEN SIGN and U+203E OVERLINE,
so these characters were converted to ujis 0x8E5C
and 0x8E7E accordingly.
This behaviour would be correct for a JIS-X-0201 based character set,
but this is wrong for UJIS, which is documented as x-eucjp-unicode-0.9,
and which is based on ASCII for the range U+0000..U+007F.
Fix:
removing JIS-X-0201 conversion rules, making UJIS ASCII compatible.
YEN SIGN and OVERLINE do not have corresponding UJIS characters anymore
and converted to 0x3F QUESTION MARK, throwing a warning in appropriative cases.
This patch also includes a test covering full UJIS->Unicode->UJIS mapping.
sql/field.cc:
Nicer error message format:
always use HEX notation when printing warnings about UCS2 values -
this is more readable.

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.

use bigint instead.

there are two options for the test passing:
1. no rows inserted and the INSERT gets killed, then there is no INSERT query in binlog
2. all rows inserted, then INSERT gets to binlog and error_code is zero
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.
sql/item_cmpfunc.cc:
Bug#28450: The Item_date_add_interval in select list may fail the field
