In a simple queries a result of the GROUP_CONCAT() function was always of
varchar type.
But if length of GROUP_CONCAT() result is greater than 512 chars and temporary
table is used during select then the result is converted to blob, due to
policy to not to store fields longer than 512 chars in tmp table as varchar
fields.
In order to provide consistent behaviour, result of GROUP_CONCAT() now
will always be converted to blob if it is longer than 512 chars.
Item_func_group_concat::field_type() is modified accordingly.
mysql-test/t/func_gconcat.test:
Added test case for bug#14169: type of group_concat() result changed to blob if tmp_table was used

sql/unireg.h:

sql/sql_select.cc:
Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used
The unnamed constant 255 in the create_tmp_field() and create_tmp_field_from_item() functions now defined as the CONVERT_IF_BIGGER_TO_BLOB constant.
The create_tmp_field() function now converts the Item_sum string result to a blob field based on its char length.
sql/item_sum.h:
Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used
To the Item_func_group_concat calls added the member function field_type() which returns the BLOB or VAR_STRING type based on the items length.
sql/item_func.cc:
Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used
In the Item_func::tmp_table_field() function the unnamed constant 255 is changed to the CONVERT_IF_BIGGER_TO_BLOB constant.
The Item_func::tmp_table_field() function now measures the result length in chars rather than bytes when converting string result to a blob.
CONNECTION_ID() was implemented as a constant Item, i.e. an instance of
Item_static_int_func class holding value computed at creation time.
Since Items are created on parsing, and trigger statements are parsed
on table open, the first connection to open a particular table would
effectively set its own CONNECTION_ID() inside trigger statements for
that table.
Re-implement CONNECTION_ID() as a class derived from Item_int_func, and
compute connection_id on every call to fix_fields().
mysql-test/r/trigger.result:
Add result for bug#16461.
mysql-test/t/trigger.test:

sql/item_create.cc:

sql/item_func.cc:
Re-implement CONNECTION_ID() as Item_func_connection_id
(was Item_static_int_func). Set max_length to 10, as it was before.
Compute connection_id dynamically on every call to fix_fields().
sql/item_func.h:
Re-implement CONNECTION_ID() as Item_func_connection_id
(was Item_static_int_func).
a race between updating and checking Max_used_connections. This is done in

the test will fail.
Use con1, con2, con3 instead of con3, con4, con5.

If the second or the third argument of a BETWEEN predicate was
a constant expression, like '2005.09.01' - INTERVAL 6 MONTH,
while the other two arguments were fields then the predicate
was evaluated incorrectly and the query returned a wrong
result set.
The bug was introduced in 5.0.17 when in the fix for 12612.

a misnamed function
... in the presence of a continue handler. The problem was that with a
handler, it continued to execute as if function existed and had set a
useful return value (which it hadn't).
The fix is to set a null return value and do an error return when a function
wasn't found.
mysql-test/r/sp.result:
Updated results for a new test case (BUG#18787).
mysql-test/t/sp.test:
New testcase for BUG#18787.
sql/item_func.cc:
Don't set "out of resources" error in Item_func_sp::execute() if no
result field is returned, it's simply wrong, it can be sometthing else,
like a function not found. Instead set null_value and return error.
Also, set "out of resources" when field creation fails in
Item_func_sp::sp_result_field() and Item_func_sp::tmp_table_field().

The function agg_cmp_type in item_cmpfunc.cc neglected the fact that
the first argument in a BETWEEN/IN predicate could be a field of a view.
As a result in the case when the retrieved table was hidden by a view
over it and the arguments in the BETWEEN/IN predicates are of
the date/time type the function did not perform conversion of
the constant arguments to the same format as the first field argument.
If formats of the arguments differed it caused wrong a evaluation of
the predicates.

too many open statements". The patch adds a new global variable
@@max_prepared_stmt_count. This variable limits the total number
of prepared statements in the server. The default value of
@@max_prepared_stmt_count is 16382. 16382 small statements
(a select against 3 tables with GROUP, ORDER and LIMIT) consume
100MB of RAM. Once this limit has been reached, the server will
refuse to prepare a new statement and return ER_UNKNOWN_ERROR
(unfortunately, we can't add new errors to 4.1 without breaking 5.0). The limit is changeable after startup
and can accept any value from 0 to 1 million. In case
the new value of the limit is less than the current
statement count, no new statements can be added, while the old
still can be used. Additionally, the current count of prepared
statements is now available through a global read-only variable
@@prepared_stmt_count.

Test results fixed (a test case for Bug#16365)

sql/mysql_priv.h:

sql/mysqld.cc:
Add definitions of max_prepared_stmt_count, prepared_stmt_count.
sql/set_var.cc:
Implement support for @@prepared_stmt_count and

without acquiring LOCK_prepared_stmt_count due to limitations of
the set_var/sys_var class design. Updates are, however, protected
with a lock.

New declarations to add support for @@max_prepared_stmt_count.
Implement a new class, where the lock to be used when updating

sql/item_row.cc:
Implement Item_row::cleanup(): we should reset used_tables_cache
before reexecution of a prepared statement. In case ROW
arguments contain a placeholder, used_tables_cache has PARAM_TABLE
bit set in statement prepare. As a result, when executing a statement,
the condition push down algorithm (make_cond_for_table) would think
that the WHERE clause belongs to the non-existent PARAM_TABLE and
wouldn't attach the WHERE clause to any of the real tables,
effectively optimizing the clause away.
sql/item_row.h:
Remove a never used member 'array_holder'. Add declaration for
Item_row::cleanup.
