The server variable opt_secure_file_priv wasn't
normalized properly and caused the operations
LOAD DATA INFILE .. INTO TABLE ..
and
SELECT load_file(..)
to do different interpretations of the
--secure-file-priv option.
The patch moves code to the server initialization
routines so that the path always is normalized
once and only once.
It was also intended that setting the option
to an empty string should be equal to
lifting all previously set restrictions. This
is also fixed by this patch.
sql/mysqld.cc:
* If --secure_file_option is an empty string then the option variable
should be unset.
* opt_secure_file_option should be normalized once when the server starts.
sql/sql_load.cc:
* moved variable normalization code to fix_paths()
Arg_comparator initializes 'comparators' array in case of
ROW comparison and does not free this array on destruction.
It leads to memory leaks.
The fix:
-added Arg_comparator::cleanup() method which frees
'comparators' array.
-added Item_bool_func2::cleanup() method which calls
Arg_comparator::cleanup() method

When re-setting (SET GLOBAL debug='') the GLOBAL debug settings the
server was not freeing the data elements from the top (initial) frame
before setting them to 0 without freeing the underlying memory. As these
are global settings there's a chance that something is there already.
Fixed by :
1. making sure the allocated data are cleaned up before re-setting them
while parsing a debug string
2. making sure the stuff allocated in the global settings is freed on
shutdown.
union...order by (select... where...)
The problem is mysql is trying to materialize and
cache the scalar sub-queries at JOIN::optimize
even for EXPLAIN where the number of columns is
totally different from what's expected.
Fixed by not executing the scalar subqueries
for EXPLAIN.
they are ignored to a new test suite "innodb_plugin".
Remove a hack in mtr that was deployed to run the builtin InnoDB tests against
the InnoDB Plugin. Also detect if a test is an 'innodb plugin test' and if so
then transparently replace the builtin InnoDB with the InnoDB Plugin.

on LOAD DATA
Two problems :
1. LOAD DATA was not checking for SQL errors and was sending an OK
packet even when there were errors reported already. Fixed to check for
SQL errors in addition to the error conditions already detected.
2. There was an over-ambitious assert() on the server to check if the
protocol is always followed by the client. This can cause crashes on
debug servers by clients not completing the protocol exchange for some
reason (e.g. --send command in mysqltest). Fixed by keeping the assert
only on client side, since the server always completes the protocol
exchange.

The problem is that we can not use make_cond_for_table().
This function relies on used_tables() condition
which is not set properly for subqueries.
As result subquery is not filtered out.
The fix is to use remove_eq_conds() function instead
of make_cond_for_table() func. 'remove_eq_conds()'
algorithm relies on const_item() value and it allows
to handle subqueries in right way.

Procedure, while DECIMAL works
Selecting of the CONCAT(...<SP variable>...) result into
a user variable may return wrong data.
Item_func_concat::val_str contains a number of memory
allocation-saving tricks. One of them concatenates
strings inplace inserting the value of one string
at the beginning of the other string. However,
this trick didn't care about strings those points
to the same data buffer: this is possible when
a CONCAT() parameter is a stored procedure variable -
Item_sp_variable::val_str() uses the intermediate
Item_sp_variable::str_value field, where it may
store a reference to an external buffer.
The Item_func_concat::val_str function has been
modified to take into account val_str functions
(such as Item_sp_variable::val_str) that return
a pointer to an internal Item member variable
that may reference to a buffer provided.

'my_decimal' class has two members which can be used to access the
value. The member variable buf (inherited from parent class decimal_t)
is set to member variable buffer so that both are pointing to same value.
Item_copy_decimal::copy() uses memcpy to clone 'my_decimal'. The member
buffer is declared as an array and memcpy results in copying the values
of the array, but the inherited member buf, which should be pointing at
the begining of the array 'buffer' starts pointing to the begining of
buffer in original object (which is being cloned). Further updates on
'my_decimal' updates only the inherited member 'buf' but leaves
buffer unchanged.
Later when the new object (which now holds a inconsistent value) is cloned
again using proper cloning function 'my_decimal2decimal' the buf pointer
is fixed resulting in loss of the current value.
Using my_decimal2decimal instead of memcpy in Item_copy_decimal::copy()
fixed this problem.
