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.
mysql-test/r/ps.result:
Test results fixed (a test case for Bug#16365)
mysql-test/t/ps.test:
A test case for Bug#16365 "Prepared Statements: DoS with too many
open statements". Also fix statement leaks in other tests.
sql/mysql_priv.h:
Add declarations for new global variables.
sql/mysqld.cc:
Add definitions of max_prepared_stmt_count, prepared_stmt_count.
sql/set_var.cc:
Implement support for @@prepared_stmt_count and
@@max_prepared_stmt_count. Currently these variables are queried
without acquiring LOCK_prepared_stmt_count due to limitations of
the set_var/sys_var class design. Updates are, however, protected
with a lock.
sql/set_var.h:
New declarations to add support for @@max_prepared_stmt_count.
Implement a new class, where the lock to be used when updating
a variable is a parameter.
sql/sql_class.cc:
Add accounting of the total number of prepared statements in the
server to the methods of Statement_map.
sql/sql_class.h:

Statement_map::insert will now send a message in case of an

The GROUP_CONCAT uses its own temporary table. When ROLLUP is present
it creates the second copy of Item_func_group_concat. This copy receives the
same list of arguments that original group_concat does. When the copy is
set up the result_fields of functions from the argument list are reset to the
temporary table of this copy.
As a result of this action data from functions flow directly to the ROLLUP copy
and the original group_concat functions shows wrong result.
Since queries with COUNT(DISTINCT ...) use temporary tables to store
the results the COUNT function they are also affected by this bug.
The idea of the fix is to copy content of the result_field for the function
under GROUP_CONCAT/COUNT from the first temporary table to the second one,
rather than setting result_field to point to the second temporary table.
To achieve this goal force_copy_fields flag is added to Item_func_group_concat
and Item_sum_count_distinct classes. This flag is initialized to 0 and set to 1
into the make_unique() member function of both classes.
To the TMP_TABLE_PARAM structure is modified to include the similar flag as
well.
The create_tmp_table() function passes that flag to create_tmp_field().
When the flag is set the create_tmp_field() function will set result_field
as a source field and will not reset that result field to newly created
field for Item_func_result_field and its descendants. Due to this there
will be created copy func to copy data from old result_field to newly
created field.

Now thd->mem_root is a pointer to thd->main_mem_root and THR_MALLOC is a pointer to thd->mem_root.
This gives us the following benefits:
- Allow us to easily detect if arena has already been swapped before (this fixes a bug in setup_conds() where arena was swaped twice in some cases)
- Faster swaps of arenas (as we don't have to copy the whole MEM_ROOT)
- We don't anymore have to call my_pthread_setspecific_ptr(THR_MALLOC,...) to change where memory is alloced. Now it's enough to set thd->mem_root

sql/sql_prepare.cc:
Deploy mysql_reset_thd_for_next_query to reset THD state before

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).

crashes mysqld": implementation for a generic item tree modifications
registry. Every item tree modification which should be rolled back for
subsequent execution of a prepared statement or stored procedure should
be saved in the registry. All such modifications are rolled back at once
during cleanup stage of PS.
Actual fix for the bug just adds a call to register modifications to
convert_constant_item.
Post review fixes implemented.
mysql-test/r/ps.result:
A fix for bug#5748, test results fixed.

A test case for Bug#5748 "Prepared statement with BETWEEN and bigint
values crashes mysqld"
sql/item.cc:
Fix for Bug#5748 "Prepared statement with BETWEEN and bigint values
crashes mysqld":
First step in removing up item-specific cleanups: now all such
tree modifications should be done using the genericm mechanism implemented
in this changeset.
sql/item.h:
Fix for Bug#5748 "Prepared statement with BETWEEN and bigint values
crashes mysqld": no need for an item-specific change record any more.
sql/item_cmpfunc.cc:
A fix for Bug#5748 "Prepared statement with BETWEEN and bigint
values crashes mysqld": register item tree transformation performed by
convert_constant_item.
sql/sql_class.cc:
Implementation for item tree transformations registry.
sql/sql_class.h:
Declarations, necessary for the tree transformations registry.
sql/sql_parse.cc:
Assert that the item tree transformations registry is not used for
conventional execution.
sql/sql_prepare.cc:
Use of the item tree modifications registry in prepared statements:
rollback all modifications in the end of statement prepare and execute.
Also we now always set thd->current_arena to be able to determine that
this is an execution of prepared statement inside the registry code.
tests/client_test.c:
A typo fixed.
Noteworthy:
- New HANDLER code
- New multi-update-grant-check code
- Table lock code in ha_innodb.cc was not applied

BUG#4335 - one name can be handler open'ed many times.
Reworked the HANDLER functions and interface.
Using a HASH to store information on open tables that
survives FLUSH TABLE.
HANDLER tables alias names must now be unique, though it
is allowed in 4.0 to qualify them with the database name
of the base table.
mysql-test/r/flush_table.result:
BUG#4286 - HANDLER tables are closed by FLUSH TABLE(S).
BUG#4335 - one name can be handler open'ed many times.
Moved pure handler test results to handler.result.

sql/sql_class.cc:
BUG#4286 - HANDLER tables are closed by FLUSH TABLE(S).
BUG#4335 - one name can be handler open'ed many times.

Changed the handler tables clean-up code.
Unreleted to bug: Changed the order of THD initialization
to avoid warning messages on Linux with gcc.
sql/sql_class.h:
BUG#4286 - HANDLER tables are closed by FLUSH TABLE(S).

with memory roots in THD/Statement/Item_arena.
Added assertions preventing memory allocation on bzero'ed MEM_ROOT since it is worked by
pure luck and was very ineffective.
include/my_sys.h:
Reimplementation of Monty's optimization of clear_alloc_root().
Now clear_alloc_root() can be used only for detaching memory associated with MEM_ROOT
(e.g. to avoid its freeing). It can not be used for MEM_ROOT initialization any longer
(it was bad idea anyway since memory allocation on such MEM_ROOT was very ineffective
and worked by pure luck).
Introduced ALLOC_ROOT_MIN_BLOCK_SIZE constant.
mysys/my_alloc.c:
Added description of init_alloc_root().
Added assertions to alloc_root() and reset_root_defaults() so now they can only be used
on previosly initialized MEM_ROOT. (It worked for bzeroed MEM_ROOT before but
by pure luck and very inefficiently). Calling free_root() on bzero'ed MEM_ROOT
is still ok (we can't remove this easily because of static MEM_ROOTs).
Also now using ALLOC_ROOT_MIN_BLOCK_SIZE constant inside these functions.
sql/opt_range.cc:
Fixed get_quick_select_for_ref() function to not use bzero'ed MEM_ROOT for allocation.
Also QUICK_RANGEs created in this function should be created in memory root of QUICK_SELECT.
sql/sql_class.cc:
Implementation of Monty's idea about clear_alloc_root() optimization and cleanup of work
with memory roots in THD/Statement/Item_arena.
Now we are always initing THD::transaction.mem_root and THD::mem_root in THD constructor
(without memory allocation and with minimal block size) and then later change their
parameters in THD::init_for_queries() (this is partially because we can't allocate anything
on bzero'ed memory roots anymore).
Item_arena() constructor is now trivial and is used only then Item_arena is created as backup
storage for other Item_arena (we use Item_arena(bool) now if it is part of Statement).
Both trivial Item_arena constructor and destructor are now inline.
Removed unneeded clear_alloc_root from Item_arena::restore_backup_item_arena().
sql/sql_class.h:
Both trivial Item_arena constructor and destructor are now inline.
Commented various Item_arena constructors.
prepared statements."
include/hash.h:
New declaration for hash_reset() function. The old version was not used.
libmysql/client_settings.h:
Declaration for mysql_detach_stmt_list().
libmysql/libmysql.c:
Fix for bug#5315 "mysql_change_user() doesn't free prepared statements":
add call to mysql_detach_stmt_list(prepared statements) to
mysql_change_user(): all statements are freed by server, so client
counterparts need to be marked as not usable.
mysys/hash.c:
Fix for bug#5315 "mysql_change_user() doesn't free prepared statements":
implementation of hash_reset(), which frees all hash elements
and prepares the hash for reuse.
sql-common/client.c:
Fix for bug#5315 "mysql_change_user() doesn't free prepared statements":
implementation of mysql_detach_stmt_list(): zero connection pointer
in given statement list, thus marking given statements as not usable.
sql/sql_class.cc:
Fix for bug#5315 "mysql_change_user() doesn't free prepared statements":
reset prepared statements map in THD::change_user().
sql/sql_class.h:
Fix for bug#5315 "mysql_change_user() doesn't free prepared statements":
implementation of Statement_map::reset().
A little cleanup of ~Statement_map(): first empty names_hash, as st_hash
has a free function, which will delete statements.
tests/client_test.c:
A test case for bug #5315 "mysql_change_user() doesn't free prepared
statements".
