The problem is that cond->fix_fields(thd, 0) breaks
condition(cuts off 'having'). The reason of that is
that NULL valued Item pointer is present in the
middle of Item list and it breaks the Item processing
loop.

sql/item_cmpfunc.h:
added ASSERT to make sure that we do not add NULL valued Item pointer

skip adding an item to condition if Item pointer is NULL.
skip adding a list to condition if this list is empty.
performance degradation.
Filesort + join cache combination is preferred to full index scan because it
is usually faster. But it's not the case when the index is clustered one.
Now test_if_skip_sort_order function prefers filesort only if index isn't
clustered.
mysql-test/r/innodb_mysql.result:
Added a test case for the bug#50843.
mysql-test/t/innodb_mysql.test:
Added a test case for the bug#50843.
sql/sql_select.cc:
Bug#50843: Filesort used instead of clustered index led to
performance degradation.
Now test_if_skip_sort_order function prefers filesort only if index isn't
clustered.
Propagation of a large unsigned numeric constant
in the WHERE expression led to wrong result.
For example,
"WHERE a = CAST(0xFFFFFFFFFFFFFFFF AS USIGNED) AND FOO(a)",
where a is an UNSIGNED BIGINT, and FOO() accepts strings,
was transformed to "... AND FOO('-1')".
That has been fixed.
Also EXPLAIN EXTENDED printed incorrect numeric constants in
transformed WHERE expressions like above. That has been
fixed too.
mysql-test/r/bigint.result:
Added test case for bug #45360.
mysql-test/t/bigint.test:
Added test case for bug #45360.
sql/item.cc:
Bug #45360: wrong results
As far as Item_int_with_ref (and underlaying Item_int)
class accepts both signed and unsigned 64bit values,
Item_int::val_str and Item_int::print methods have been
modified to take into account unsigned_flag.
The problem was in an incorrect debug assertion. The expression
used in the failing assertion states that when finding
references matching ORDER BY expressions, there can be only one
reference to a single table. But that does not make any sense,
all test cases for this bug are valid examples with multiple
identical WHERE expressions referencing the same table which
are also present in the ORDER BY list.
Fixed by removing the failing assertion. We also have to take
care of the 'found' counter so that we count multiple
references only once. We rely on this fact later in
eq_ref_table().
mysql-test/r/join.result:
Added a test case for bug #50335.
mysql-test/t/join.test:
Added a test case for bug #50335.
sql/sql_select.cc:
Removing the assertion in eq_ref_table() as it does not make
any sense. We also have to take care of the 'found' counter so
that we count multiple references only once. We rely on this
fact later in eq_ref_table().
"TYPE=storage_engine" is deprecated, and will be removed
in the Celosia release of MySQL. Since the option is
present in the Betony release and the version number of
Celosia is still not decided, we need to bump the
deprecation version number back up to "6.0".

This is the final patch in the context of this bug.
cmd-line-utils/readline/rlmbutil.h:
Changed in a previous patch, reverted by a backport.
cmd-line-utils/readline/text.c:
Static var initialization.

SetErrorString handles errors outside of the YasslError

There was an erroneous parameter when calling flush_master_info
from write_ignored_events_info_to_relay_log which could lead to a
server crash. This happens because the I/O thread releases the
log_lock before calling the flush_master_info.
Set the function to call flush_master_info with third parameter
to true, so that the mutex is properly taken.
When EXPLAIN EXTENDED tries to print column names, it checks whether the
referenced table is CONST (in which case, the column's value rather than
its name will be printed). If no proper table is reference (i.e. because
a derived table was used that has since gone out of scope), this will fail
spectacularly.
This ports an equivalent of the fix for Bug 43354.
mysql-test/r/func_gconcat.result:
Show that EXPLAIN EXTENDED on a GROUP_CONCAT() on a derived table
no longer crashes the server.
mysql-test/t/func_gconcat.test:
Show that EXPLAIN EXTENDED on a GROUP_CONCAT() on a derived table
no longer crashes the server.
sql/item_sum.cc:
Do not de-ref what cannot be, that is, temp-tables that have gone away.
This is of questionable utility anyway, since our deref has the sole
purpose of checking whether the table is const (in which case, we'll
substitute the column with its value in EXPLAIN EXTENDED - that is all).
CHECK_FIELD_IGNORE was treated as CHECK_FIELD_ERROR_FOR_NULL;
UPDATE...SET...NULL on NOT NULL fields behaved differently after
a trigger.
Now distinguishes between IGNORE and ERROR_FOR_NULL and save/restores
check-field options.

Show that UPDATE...SET...NULL on NOT NULL columns doesn't behave differently
when run after a trigger.
mysql-test/t/trigger.test:
Show that UPDATE...SET...NULL on NOT NULL columns doesn't behave differently
when run after a trigger.
sql/field_conv.cc:
CHECK_FIELD_IGNORE was treated as CHECK_FIELD_ERROR_FOR_NULL.
Distinguish between the two.

Table corruption happens during table reading in ha_tina::find_current_row() func.
Field::store() method returns error(true) if stored value is 0.
The fix:
added special case for enum type which correctly processes 0 value.
Additional fix:
INSERT...(default) and INSERT...() have the same behaviour now for enum type.

Some logic would group by suite always
Disable this if using --noreorder
Also fix getting array from collect_one_suite() in this case
Amended according to previous comment
A "%define" is no shell command, so it must not be the
only line in the "then" or "else" branch of an "if".
Add a ':' line to make the branch non-empty.
