some rollup rows (rows with NULLs for grouping attributes) if GROUP BY
list contained constant expressions.
This happened because the results of constant expressions were not put
in the temporary table used for duplicate elimination. In fact a constant
item from the GROUP BY list of a ROLLUP query can be replaced for an
Item_null_result object when a rollup row is produced .
Now the JOIN::rollup_init function wraps any constant item referenced in
the GROYP BY list of a ROLLUP query into an Item_func object of a special
class that is never detected as constant item. This ensures creation of
fields for such constant items in temporary tables and guarantees right
results when the result of the rollup operation first has to be written
into a temporary table, e.g. in the cases when duplicate elimination is
required.

Fixed bug #24856: the result set of a ROLLUP query with DISTINCT could lack
some rollup rows (rows with NULLs for grouping attributes) if GROUP BY
list contained constant expressions.
Itroduced class Item_func_rollup_const derived from Item_func. The object of
this class are never detected as constant items.
We use them for wrapping constant items from the GROUP BY list of any ROLLUP
query. This wrapping allows us to ensure writing constant items into temporary
tables whenever the result of the ROLLUP operation has to be written into a
temporary table, e.g. when ROLLUP is used together with DISTINCT in the SELECT
list.

Note: bug#21726 does not directly apply to 4.1, as it doesn't have stored
procedures. However, 4.1 had some bugs that were fixed in 5.0 by the
patch for bug#21726, and this patch is a backport of those fixes.
Namely, in 4.1 it fixes:
- LAST_INSERT_ID(expr) didn't return value of expr (4.1 specific).
- LAST_INSERT_ID() could return the value generated by current
statement if the call happens after the generation, like in
CREATE TABLE t1 (i INT AUTO_INCREMENT PRIMARY KEY, j INT);
INSERT INTO t1 VALUES (NULL, 0), (NULL, LAST_INSERT_ID());
- Redundant binary log LAST_INSERT_ID_EVENTs could be generated.
mysql-test/r/rpl_insert_id.result:
Add result for bug#21726: Incorrect result with multiple invocations

mysql-test/t/rpl_insert_id.test:
Add test case for bug#21726: Incorrect result with multiple invocations
of LAST_INSERT_ID.
sql/item_func.cc:
Add implementation of Item_func_last_insert_id::fix_fields(), where we
set THD::last_insert_id_used when statement calls LAST_INSERT_ID().
In Item_func_last_insert_id::val_int(), return THD::current_insert_id
if called like LAST_INSERT_ID(), otherwise return value of argument if
called like LAST_INSERT_ID(expr).
sql/item_func.h:
Add declaration of Item_func_last_insert_id::fix_fields().
sql/log_event.cc:
Do not set THD::last_insert_id_used on LAST_INSERT_ID_EVENT. Though we
know the statement will call LAST_INSERT_ID(), it wasn't called yet.
sql/set_var.cc:
In sys_var_last_insert_id::value_ptr(), set THD::last_insert_id_used,
and return THD::current_insert_id for @@LAST_INSERT_ID.
sql/sql_class.h:
Update comments.
Remove THD::insert_id(), as it has lost its purpose now.
sql/sql_insert.cc:
Now it is OK to read THD::last_insert_id directly.
sql/sql_load.cc:
Now it is OK to read THD::last_insert_id directly.
sql/sql_parse.cc:
In mysql_execute_command(), remember THD::last_insert_id (first
generated value of the previous statement) in THD::current_insert_id,
which then will be returned for LAST_INSERT_ID() and @@LAST_INSERT_ID.
sql/sql_select.cc:
If "IS NULL" is replaced with "= <LAST_INSERT_ID>", use right value,
which is THD::current_insert_id, and also set THD::last_insert_id_used
to issue binary log LAST_INSERT_ID_EVENT.
sql/sql_update.cc:
Now it is OK to read THD::last_insert_id directly.

On exactly-sized Strings, the String::c_ptr() function peeked beyond the
end of the buffer, possibly into unititialized space to see whether the
buffer was NUL-terminated.
In a place that did peek improperly, we now use a c_ptr_safe() function,

Final version of patch.
Adds support for specifying of DEFAULT NOW() and/or ON UPDATE NOW()
clauses for TIMESTAMP field definition.
Current implementation allows only one such field per table and
uses several unireg types for storing info about this properties of
field. It should be replaced with better implementation when new
.frm format is introduced.
include/mysqld_error.h:
Added error codes for case when we have more than one column with NOW()
in DEFAULT or ON UPDATE clauses and for case when we are using ON UPDATE
clause with wrong type.

non-TIMESTAMP fields.

mysql-test/t/type_timestamp.test:
Added tests for various DEFAULT and ON UPDATE clauses for TIMESTAMP
fields definitions.
sql/field.cc:
Added support for various combinations of DEFAULT and ON UPDATE clauses
for TIMESTAMP field.
Setting TABLE::timestamp* members for TIMESTAMP fields with auto-set
option taking into account their unireg type (which corresponds to
various DEFAULT/ON UPDATE values combinations). Replaced
TABLE::time_stamp with TABLE::timestamp_default_now/on_update_now
couple moved their setup to separate method set_timestamp_offsets(),
which now is called from open_table instead of Field_timestamp cons.
sql/field.h:
Added more unireg types for handling of DEFAULT NOW() and ON UPDATE
NOW() for TIMESTAMP fields.
Fixed value corresponding to DEFAULT item for TIMESTAMP field.
sql/ha_berkeley.cc:

INSERT or/and UPDATE independently.

We need to distinguish NOW() from other function for using in
DEFAULT and in ON UPDATE clauses.

sql/sql_base.cc:
Added setup of TABLE::timestamp_default_now/on_update_now pair
for each statement to open_table().
sql/sql_insert.cc:
Using TABLE::timestamp_default_now/on_update_now pair instead of
old TABLE::time_stamp. Added check for case then REPLACE could not
be converted to UPDATE because of different DEFAULT/ON UPDATE values
for TIMESTAMP field.
sql/sql_lex.h:
Added member for value used in ON UPDATE clause to st_lex.
sql/sql_load.cc:
Using TABLE::timestamp_default_now/on_update_now pair instead of
old TABLE::time_stamp. We don't need to restore these members
since they are set up for each statement in open_table().
sql/sql_parse.cc:
Added handling of DEFAULT NOW() and ON UPDATE NOW() clauses for
TIMESTAMP fields to add_field_to_list() function.
sql/sql_show.cc:
Added support for DEFAULT CURRENT_TIMESTAMP (aka NOW() ) and
ON UPDATE CURRENT_TIMESTAMP to SHOW CREATE TABLE and SHOW COLUMNS.

mysql_create_table() function - added check for number of TIMESTAMP
fields with auto-set values and replacing of old style TIMESTAMPs
with their newer analogs.
mysql_alter_table(): Using TABLE::timestamp_default_now/on_update_now
pair instead of old TABLE::time_stamp. We don't need to restore these
members since they are set up for each statement in open_table().
sql/sql_update.cc:
Left only setting of TABLE::timestamp_default_now/on_update_now
to 0 since they should be already set up in open_table().
sql/sql_yacc.yy:
Added support for DEFAULT NOW() and ON UPDATE NOW() in field
definitions.
sql/table.h:
Replaced TABLE::time_stamp withTABLE::timestamp_default_now/timestamp_on_update_now
pair which allows to distinguish TIMESTAMP's with various DEFAULT/ON UPDATE
clauses and optimize checks if TIMESTAMP field should be set to NOW()
in handlers.
sql/unireg.cc:
Now we are marking only TIMESTAMP fields with NOW() as default or
as on update value as special field for unireg.
This turned out to be a problem for prepared statements as well; the id was
evaluated once, at parse time.
mysql-test/r/auto_increment.result:
