aware plus it fixes the case when RAND is used in prepared
statements and replication is on (as well as several similar issues).
Until now we did not reset THD before every execution of a prepared
statement, so if some execution had set thd->time_zone_used
or thd->rand_used they would not be reset until next mysql_parse.
Some of post-review fixes done.

sql/sql_prepare.cc:
Deploy mysql_reset_thd_for_next_query to reset THD state before
execution of a prepared statement.
Normally this should have been added to just one place, but
we have to reset thd before assigning placeholders from variables,
thus we can't do that in execute_stmt (yuck).

column types TIMESTAMP is NOT NULL by default, so in order to have
TIMESTAMP column holding NULL valaues you have to specify NULL as
one of its attributes (this needed for backward compatibility).
Main changes:
Replaced TABLE::timestamp_default_now/on_update_now members with
TABLE::timestamp_auto_set_type flag which is used everywhere
for determining if we should auto-set value of TIMESTAMP field
during this operation or not. We are also use Field_timestamp::set_time()
instead of handler::update_timestamp() in handlers.
mysql-test/r/type_timestamp.result:
Added test for TIMESTAMP columns which are able to store NULL values.
mysql-test/t/type_timestamp.test:
Added test for TIMESTAMP columns which are able to store NULL values.
sql/field.cc:
Added support for TIMESTAMP fields holding NULL values.
We don't need Field_timestamp::set_timestamp_offsets() anymore.
Instead we need Field_timestamp::get_auto_set_type() function
which will convert TIMESTAMP auto-set type stored in Field in
unireg_check to value from timestamp_auto_set_type_enum.
(We can't replace this function with additional Field_timestamp member
and some code in constructor because then we will have troubles
with Field::new_field() method).
We should also set field to not null in Field_timestamp::set_time() now.
sql/field.h:
Added support for TIMESTAMP fields holding NULL values.
We don't need Field_timestamp::set_timestamp_offsets() anymore.
Instead we need Field_timestamp::get_auto_set_type() function,
which will convert TIMESTAMP auto-set type stored in Field in
unireg_check to value from timestamp_auto_set_type_enum.
We also have to support NULL values in Field_timestamp::get_timestamp()
function.
sql/field_conv.cc:
Added comment clarifying behavior in case of TIMESTAMP fields which are
able to store NULL values.
sql/ha_berkeley.cc:
Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now for determining
if we should auto-set value of TIMESTAMP field during this operation.
We are also use Field_timestamp::set_time() instead of
handler::update_timestamp().
sql/ha_heap.cc:
Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now for determining

handler::update_timestamp().
sql/ha_innodb.cc:
Now we use TABLE::timestamp_field_type instead of

We are also use Field_timestamp::set_time() instead of
handler::update_timestamp().
sql/ha_isam.cc:
Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now for determining
if we should auto-set value of TIMESTAMP field during this operation.
We are also use Field_timestamp::set_time() instead of
handler::update_timestamp().
sql/ha_isammrg.cc:

handler::update_timestamp().
sql/ha_myisam.cc:

sql/ha_ndbcluster.cc:

if we should auto-set value of TIMESTAMP field during this operation.
We are also use Field_timestamp::set_time() instead of
handler::update_timestamp().
sql/handler.cc:
handler::update_timestamp() is no longer needed since now we use
Field_timestamp::set_time() instead.
(we can't use handler::update_timestamp() anyway since field position
only is not enough for TIMESTAMP fields which are able to store NULLs)
sql/handler.h:
handler::update_timestamp() is no longer needed since now we use
Field_timestamp::set_time() instead.
sql/item_timefunc.cc:
Since now TIMESTAMP fields can hold NULL values we should take this into
account.
sql/sql_base.cc:
Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now.
(Here we use Field_timestamp::get_auto_set_type() to setup its value
before further statement execution).
sql/sql_insert.cc:
Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now.
sql/sql_load.cc:
Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now.
sql/sql_parse.cc:
Added support for TIMESTAMP fields holding NULL values.
We should distinguish NULL default values and non-specified default
values for such fields (because latter could mean DEFAULT NOW()
ON UPDATE NOW() in some cases).
sql/sql_show.cc:
Added support for TIMESTAMP fields holding NULL values.
Unlike all other fields these are NOT NULL by default
so we have to specify NULL attribute explicitly for them.
sql/sql_table.cc:
Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now.
sql/sql_update.cc:
Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now.
sql/sql_yacc.yy:
Added support for TIMESTAMP fields holding NULL values.
Unlike all other fields these are NOT NULL by default
(so we have to set NOT_NULL_FLAG properly for them).
sql/table.h:
Added timestamp_auto_set_type enum which values are used for indicating
during which operations we should automatically set TIMESTAPM field
value to current timestamp.
TABLE: Replaced timestamp_default_now/on_update_now members with
timestamp_auto_set_type flag (Now when TIMESTAMP field are able to
store NULL values, single position of field in record is not enough
for updating this field anyway).
using GROUP BY"
Now we are setting Field_timestamp::field_length to 19 in open_table()
if we are in new mode (and we are restoring it back when we are coming
back to normal mode). This also should solve potential problems with
some of LOAD DATA INFILE and SELECT * INTO in this mode.
mysql-test/r/type_timestamp.result:
Added test for bug #4131 'TIMESTAMP columns missing minutes and seconds
when using GROUP BY' and other --new mode related behavior.
mysql-test/t/type_timestamp.test:
Added test for bug #4131 'TIMESTAMP columns missing minutes and seconds
when using GROUP BY' and other --new mode related behavior.
sql/field.cc:
Added Field_timestamp::orig_field_length member for saving original
field_length value, because this member can be modified if new_mode is
in effect.
Lot of Field_timestamp code simplified and Field_timestamp::make_field()
is no longer needed because we are setting field_length to 19 if we are
in --new mode now.
sql/field.h:
Added Field_timestamp::orig_field_length member for saving original
field_length value, because this member can be modified if new_mode
is in effect.
Field_timestamp::make_field() is no longer needed because we are setting
field_length to 19 if we are in --new mode now.
sql/sql_base.cc:
If --new mode is in effect all TIMESTAMP fields should pretend that they
have length of 19. We are achieving this by setting
Field_timestamp::field_length to 19 (or original value) in open_table().
We are using TABLE::timestamp_mode variable for avoiding of unnecessary
looping over all fields of the table and setting field_length if table
was used with same new_mode value before.
Note: We do not introduce general framework for setting up Field objects
for usage with current THD here because this fix is only needed in 4.0
and Monty said that we will also remove looping over all fields when
updating table_name member at some point. This more general framework
will also complicate nice optimization with avoiding of unneeded looping.
sql/sql_parse.cc:
Now when we are creating TIMESTAMP(19) fields by default in --new mode,
otherwise we will have unaligned behavior between ALTER and CREATE.
sql/table.h:
Added TABLE::timestamp_mode field for saving information whenever we set
field_length members of table's TIMESTAMP fields to 19 (to honor
new_mode) or they have original values.
Added code to adjust the field_length of user variables
in dependence on the field type.
Aded new constants for numeric field widths.
include/mysql_com.h:
BUG#4788 - show create table provides incorrect statement.
Introduced definitions for default field width of numeric types.

execute crashes server": we were deleting lex->result
after each execute, but prepared statements assumed that
it's left intact.
The fix adds cleanup() method to select_result hierarchy,
so that result objects can be reused.
Plus we now need to delete result objects more wisely.
mysql-test/r/ps.result:
Test results fixed: test case for bug#5034
mysql-test/t/ps.test:
A test case for bug#5034, few followups
sql/sql_class.cc:
- fix warning in THD::THD
- implementation of cleanup() for select_result hierarchy
- select_export::send_eof was identical to
select_dump::send_eof: moved to the base class select_to_file.
- Statement::end_statement() to end lex, free items, and
delete possible select_result
sql/sql_class.h:
- select_result::cleanup() declaration
-
sql/sql_insert.cc:
- implementation of select_insert::cleanup(): currently
we always create a new instance of select_insert/
select_create on each execute.
sql/sql_lex.cc:
- with more complicated logic of freeing lex->result it's
easier to have it non-zero only if it points to a valid
result.
sql/sql_lex.h:
Now st_lex::st_lex is not empty.
sql/sql_parse.cc:
mysql_execute_command():
- delete select_result *result only if it was created in
this function.
- use end_statement() to cleanup lex and thd in the end of
each statement.
- no need to save THD::lock if this is explain. This save
apparently left from times when derived tables were
materialized here, not in open_and_lock_tables.
sql/sql_prepare.cc:
- call result->cleanup() in reset_stmt_for_execute
- now Statement is responsible for freeing its lex->result.
sql/sql_select.cc:
handle_select():
- don't delete result, it might be needed
for next executions
- result is never null
