Item::val_xxx() may be called by the server several times at execute time
for a single query. Calls to val_xxx() may be very expensive and sometimes
(count(distinct), sum(distinct), avg(distinct)) not possible.
To avoid that problem the results of calculation for these aggregate
functions are cached so that val_xxx() methods just return the calculated
value for the second and subsequent calls.

Problem: SHOW CREATE TABLE printed garbage in table
name for tables having TURKISH I
(i.e. LATIN CAPITABLE LETTER I WITH DOT ABOVE)
when lower-case-table-name=1.
Reason: In some cases during lower/upper conversion in utf8,
the result string can be shorter the original string
(including the above letter). Old implementation of caseup_str()
and casedn_str() didn't handle the result length properly,
assuming that length cannot change.
This fix changes the result type of cs->cset->casedn_str()
and cs->cset->caseup_str() from VOID to UINT, to return
the result length, as well as put '\0' terminator on a
proper place.
Also, my_caseup_str_utf8() and my_casedn_str_utf8() were
rewritten not to use strlen() for performance purposes.
It was done with help of adding of new functions - my_utf8_uni_no_range()
and my_uni_utf8_no_range() - for null terminated strings.

sql/sql_delete.cc:
Fix for bug #23412: delete rows with null date field
- during SELECT queries processing we convert 'date[time]_field is null'
conditions into 'date[time]_field = 0000-00-00[ 00:00:00]' for not null
DATE and DATETIME fields. To be consistent, we have to do the same for DELETE
queries. So we should call remove_eq_conds() in the mysql_delete() as well.
Also it may simplify and speed up DELETE queries execution.
a updatable view.
When there's a VIEW on a base table that have AUTO_INCREMENT column, and
this VIEW doesn't provide an access such column, after INSERT to such
VIEW LAST_INSERT_ID() did not return the value just generated.
This behaviour is intended and correct, because if the VIEW doesn't list
some columns then these columns are effectively hidden from the user,
and so any side effects of inserting default values to them.
However, there was a bug that such statement inserting into a view would
reset LAST_INSERT_ID() instead of leaving it unchanged.
This patch restores the original value of LAST_INSERT_ID() instead of
resetting it to zero.

- 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.

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

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.

If the error happens during DELETE IGNORE, nothing could be send to the
client, thus leaving it frozen expecting the reply.
The problem was that if some error occurred, it wouldn't be reported to
the client because of IGNORE, but neither success would be reported.
MySQL 4.1 would not freeze the client, but will report
ERROR 1105 (HY000): Unknown error
instead, which is also a bug.
The solution is to report success if we are in DELETE IGNORE and some
non-fatal error has happened.

The SQL parser was using Item::name to transfer user defined function attributes
to the user defined function (udf). It was not distinguishing between user defined
function call arguments and stored procedure call arguments. Setting Item::name
was causing Item_ref::print() method to print the argument as quoted identifiers
and caused views that reference aggregate functions as udf call arguments (and
rely on Item::print() for the text of the view to store) to throw an undefined
identifier error.
Overloaded Item_ref::print to print aggregate functions as such when printing
the references to aggregate functions taken out of context by split_sum_func2()
Fixed the parser to properly detect using AS clause in stored procedure arguments
as an error.
Fixed printing the arguments of udf call to print properly the udf attribute.
