on large length
Problem: Most (all) of the numeric inputs were being coerced into
int (32 bit) sized variables. Works OK for sane inputs; any input
larger than 2^32 (or 2^31 for signed vars) exihibited predictable
wrapping behavior (up to about 10^18) and then started having really
strange behaviour past that point (since the conversion to 64 bit int
from the DECIMAL type can do weird things on out of range numbers).
Solution: 1) Add many tests. 2) Convert input from (u)long type to
(u)longlong. 3) Do (sometimes multiple) sanity checks on input,
keeping in mind that sometimes a negative longlong is not a negative
longlong (if the unsigned_flag is set). 4) Emulate existing behavior
w/rt negative and "small" out-of-bounds values.

- When returning metadata for scalar subqueries the actual type of the
column was calculated based on the value type, which limits the actual
type of a scalar subselect to the set of (currently) 3 basic types :
integer, double precision or string. This is the reason that columns
of types other then the basic ones (e.g. date/time) are reported as
being of the corresponding basic type.
Fixed by storing/returning information for the column type in addition
to the result type.

Problem: GROUP_CONCAT on a multi-byte column can truncate
in the middle of a multibyte character when applying
group_concat_max_len limit. It produces an invalid
multi-byte character in the result string.
The second, easier version - reusing old "warning_for_row" flag,
instead of introducing of "result_is_full" - which was
added in the previous commit.

The parser is allocating Item_field for references by name in ORDER BY
expressions. Such expressions however may point not only to Item_field
in the select list (or to a table column) but also to an arbitrary Item.
This causes Item_field::fix_fields to throw an error about missing
column.
The fix substitutes Item_field for the reference with an Item_ref when
not pointing to Item_field.

(4.1 version, with post-review fixes)
The fix for another Bug (6439) limited FROM_UNIXTIME() to
TIMESTAMP_MAX_VALUE which is 2145916799 or 2037-12-01 23:59:59 GMT,
however unix timestamp in general is not considered to be limited
by this value. All dates up to power(2,31)-1 are valid.
This patch extends allowed TIMESTAMP range so, that max
TIMESTAMP value is power(2,31)-1. It also corrects
FROM_UNIXTIME() and UNIX_TIMESTAMP() functions, so that
max allowed UNIX_TIMESTAMP() is power(2,31)-1. FROM_UNIXTIME()
is fixed accordingly to allow conversion of dates up to
2038-01-19 03:14:07 UTC. The patch also fixes CONVERT_TZ()
function to allow extended range of dates.
The main problem solved in the patch is possible overflows
of variables, used in broken-time representation to time_t
conversion (required for UNIX_TIMESTAMP).
acinclude.m4:
Add new macro to check time_t range
configure.in:
Call the macro to check time_t range
include/my_time.h:
Move time-related defines to proper place.
Add a function to perform a rough check if

Note: it is defined as "static inline", as
otherwise libmysql won't compile (due to the
way how gcc handles "inline" directive).

sync using replicate-wild-ignore-table
Problem: changes in character set variables
before an action on an replication-ignored table
makes slave to forget new variable values.
Fix: initialize one_shot variables only when
4.1 -> 5.x replication is running.
mysql-test/r/rpl_ignore_table.result:
Adding test case

Don't replicate tables with names starting with "tmptbl"
mysql-test/t/rpl_ignore_table.test:

sql/sql_parse.cc:
Reset one_shot variables only if we do 4.1->5.x replication.
In other cases we cannot do that: resetting thd->variables out of sync with
st_relay_log_info::cached_charset, which makes
st_relay_log_info::cached_charset_compare() not to notice
character set related variables changes afterwards.
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.
