TIMESTAMP field when no value has been provided.

The LOAD DATA sets the current time in the TIMESTAMP field with
CURRENT_TIMESTAMP default value when the field is detected as a null.
But when the LOAD DATA command loads data from a file that doesn't contain
enough data for all fields then the rest of fields are simply set to null
without any check. This leads to no value being inserted to such TIMESTAMP
field.

Now the read_sep_field() and the read_fixed_length() functions set current
time to the TIMESTAMP field with CURRENT_TIMESTAMP default value in all cases
when a NULL value is loaded to the field.

  Added a test case for the bug#27670: LOAD DATA does not set CURRENT_TIMESTAMP
  default value for a TIMESTAMP field when no value has been provided.

 fixed coverage of out-of-mem errors

The LEAST/GREATEST functions compared DATE/DATETIME values as
strings which in some cases could lead to a wrong result.

A new member function called cmp_datetimes() is added to the
Item_func_min_max class. It compares arguments in DATETIME context
and returns index of the least/greatest argument.
The Item_func_min_max::fix_length_and_dec() function now detects when
arguments should be compared in DATETIME context and sets the newly
added flag compare_as_dates. It indicates that the cmp_datetimes() function
should be called to get a correct result.
Item_func_min_max::val_xxx() methods are corrected to call the
cmp_datetimes() function when needed.
Objects of the Item_splocal class now stores and reports correct original
field type.

When checking for applicability of join cache
we must disable its usage only if there is no
temp table in use.
When a temp table is used we can use join
cache (and it will not make the result-set 
unordered) to fill the temp table. The filesort() 
operation is then applied to the data in the temp 
table and hence is not affected by join cache
usage.
Fixed by narrowing the condition for disabling 
join cache to exclude the case where temp table
is used.

Non-correlated scalar subqueries may get executed
in EXPLAIN at the optimization phase if they are
part of a right hand sargable expression.
If the scalar subquery uses a temp table to 
materialize its results it will replace the 
subquery structure from the parser with a simple
select from the materialization table.
As a result the EXPLAIN will crash as the 
temporary materialization table is not to be shown
in EXPLAIN at all.
Fixed by preserving the original query structure
right after calling optimize() for scalar subqueries
with temp tables executed during EXPLAIN.

The generic string to int conversion was used by the Item_func_signed and
the Item_func_unsigned classes to convert DATE/DATETIME values to the
SIGNED/UNSIGNED type. But this conversion produces wrong results for such
values.

Now if the item which result has to be converted can return its result as
longlong then the item->val_int() method is used to allow the item to carry
out the conversion itself and return the correct result.
This condition is checked in the Item_func_signed::val_int() and the
Item_func_unsigned::val_int() functions.

(here: "scripts/mysql_fix_privilege_tables{.sql,_sql.c}"). Important for cross-builds.


scripts/Makefile.am:
  Generated files like "mysql_fix_privilege_tables{.sql,_sql.c}" should survive
  a "make clean", this is essential for cross-builds.
  So move them from "CLEANFILES" to "DISTCLEANFILES".

into  linux.site:/home/omer/source/bld50_2

source tarball, this is essential for cross builds, like for NetWare.


scripts/Makefile.am:
  On a fast build machine, both the source (mysql_fix_privilege_tables.sql) 
  and the generated file (mysql_fix_privilege_tables_sql.c) may have identical timestamps
  (granularity is one second only, may be too coarse).
  If that happens, the Makefile rule will fire, and "comp_sql" will be built and called -
  which fails in a cross build, like for NetWare.
  
  Prevent that by sleeping for 5 (five) seconds, this will ensure a time difference.
