Fixed some possible fatal wrong arguments to printf() style functions
Initialized some not initialized variables
Fixed bug in stored procedure and continue handlers
(Fixes Bug#22150)
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Allocation of memory for the sort buffer at each evaluation of a
subquery may take a significant amount of time if the buffer is rather big.
With the fix we allocate the buffer at the first evaluation of the
subquery and reuse it at each subsequent evaluation.
mysql-test/r/subselect.result:
Added a test case for bug #21727.
mysql-test/t/subselect.test:
Added a test case for bug #21727.
sql/item_subselect.h:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Added an implementation for Item_subselect::is_uncacheable()
returning TRUE if the engine if the subselect is uncacheable.
sql/mysql_priv.h:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Added a new boolean parameter to the filesort_free_buffers procedure.
If the value of this parameter is TRUE the procedure frees the sort_keys
buffpek buffers.
sql/records.cc:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation

Fixed bug #21727.
Made sure that st_table::pos_in_table_list would be always initialized.
sql/sql_select.cc:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation

Cleanup.
sql/table.cc:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Added st_table_list::in_subselect() returning for a table the subselect that
contains the FROM list this table is taken from (if there is any).
sql/table.h:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Added fields for sort_keys and buffpek buffers to the FILESORT_INFO structure.
This is a performance issue for queries with subqueries evaluation

Evaluate "NULL IN (SELECT ...)" in a special way: Disable pushed-down
conditions and their "consequences":
= Do full table scans instead of unique_[index_subquery] lookups.
= Change appropriate "ref_or_null" accesses to full table scans in
subquery's joins.
Also cache value of NULL IN (SELECT ...) if the SELECT is not correlated
wrt any upper select.

sql/item_cmpfunc.cc:
BUG#8804: wrong results for NULL IN (SELECT ...):

sql/item_cmpfunc.h:
BUG#8804: wrong results for NULL IN (SELECT ...):
- Made Item_in_optimizer cache the value of "NULL IN (uncorrelated select)"

sql/item_subselect.cc:
BUG#8804: wrong results for NULL IN (SELECT ...):
- When needed, wrap the predicates we push into subquery into an
Item_func_trig_cond so we're able to turn them off when evaluating
NULL IN (SELECT ...).
- Added code to evaluate NULL IN (SELECT ...) in a special way:
= In [unique_]index_subquery, do full table scan to see if there
are any rows.
= For other subqueries, change ref[_or_null] to ALL if the
ref[_or_null] was created from pushed-down predicate.

- As a sideeffect of the patch to generate lex_hash.h only once
on the machine where the source dist was produced, a problem
was found when compiling a mysqld without partition support - it
would crash when looking up the lex symbols due to mismatch between
lex.h and the generated lex_hash.h
- Remove the ifdef for partition in lex.h
- Fix minor problem with"EXPLAIN PARTITION" when not compiled with
partition(existed also without the above patch)
- Add test case that will be run when we don't have partition
support compiled into mysqld
- Return error ER_FEATURE_DISABLED if user tries to use PARTITION
when there is no support for it.
sql/lex.h:
There should be no ifdefs of features in lex.h
sql/sql_class.cc:
In line with the comment in sql_yacc.yy that we want the same output
from "EXPLAIN PARTITIONS.." regardless of wheter we have compiled in
support for partition or not, remove the ifdef so the extra field
is added to output if the DESCRIBE_PARTITIONS bit it set. Without
this patch we get a crash as the code in select_describe believes the
field is there.
sql/sql_select.cc:
Use "const" for the variable as it's a ssigned once and never changes

We miss some records sometimes using RANGE method if we have
partial key segments.
Example:
Create table t1(a char(2), key(a(1)));
insert into t1 values ('a'), ('xx');
select a from t1 where a > 'x';
We call index_read() passing 'x' key and HA_READ_AFTER_KEY flag
in the handler::read_range_first() wich is wrong because we have
a partial key segment for the field and might miss records like 'xx'.
Fix: don't use open segments in such a case.

instead of HA_READ_AFTER_KEY.
