in cursors.
libmysql/libmysql.c:
- reset_stmt_handle(): don't reset the server side just because we have
an open cursor: the server will close the cursor automatically if
needed
sql/sql_prepare.cc:
- implement Prepared_statement::close_cursor,
- implicitly close an open cursor in mysql_stmt_execute instead of
issuing an error (to reduce the need to explicitly close cursors
and save network bandwidth).
- cleanup
sql/sql_select.cc:
Remove a destructor: cursor destruction can not be done by simply
calling a destructor, because of cross-references between cursor
and statement memory.
sql/sql_select.h:
- add an empty Cursor destructor
tests/mysql_client_test.c:
- remove a test for dropped functionality
data": remove the fix for another bug (8807) that
added OUTER_REF_TABLE_BIT to all subqueries that used a placeholder
to prevent their evaluation at prepare. As this bit hanged in
Item_subselect::used_tables_cache for ever, a constant subquery with
a placeholder was never evaluated as such, which caused wrong
choice of the execution plan for the statement.
- to fix Bug#8807 backport a better fix from 5.0
- post-review fixes.
mysql-test/r/ps.result:
Bug#11458: test results fixed
mysql-test/t/ps.test:
- add a test case for Bug#11458 "Prepared statement with subselects return
random data"
sql/item.cc:
- remove unnecessary Item_param::fix_fields
- fix Item_param::set_null to set item_type accordingly (safety:
Item_param should behave like a basic constant).
sql/item.h:
Remove Item_param::fix_fields
sql/item_subselect.h:
Remove no more existing friend.
sql/mysql_priv.h:
Add UNCACHEABLE_PREPARE to mark all subqueries as uncacheable if
in statement prepare (backport from 5.0).
sql/sql_lex.h:
Comment fixed.
sql/sql_parse.cc:
If in statement prepare, mark all subqueries as uncacheable (backport
from 5.0)
sql/sql_prepare.cc:
Switch off the uncacheable flag from all subqueries after statement
prepare is done (backport from 5.0)

We need every instruction to have its own arena, because we want to
track instruction's state (INITIALIZED_FOR_SP -> EXECUTED). Because of
`if' statements and other conditional instructions used in stored
procedures, not every instruction of a stored procedure gets executed
during the first (or even subsequent) execution of the procedure.
So it's better if we track the execution state of every instruction
independently.
All instructions of a given procedure now also share sp_head's
mem_root, but keep their own free_list.
This simplifies juggling with free Item lists in sp_head::execute.
- free_items() moved to be a member of Query_arena.
- logic of 'backup_arena' debug member of Query_arena has been
changed to support
multi-backups. Until now, TRUE 'backup_arena' meant that there is
exactly one active backup of the THD arena. Now it means simply that
the arena is used for backup, so that we can't accidentally overwrite an
existing backup. This allows doing multiple backups, e.g. in
sp_head::execute and Cursor::fetch, when THD arena is already backed up
but we want to set yet another arena (usually the 'permanent' arena,
to save permanent transformations/optimizations of a parsed tree).
sql/sp_head.cc:
- use Query_arena support in sp_head::execute() as now sp_instr inherites
from it.
sql/sp_head.h:
- inherite sp_instr from Query_arena
sql/sql_class.cc:
- changed the principle of Query_arena::backup_arena; free_items is now
a member of Query_arena.
sql/sql_class.h:

free_items() now automatically sets free_list to zero.

Bug#8367 "low log doesn't gives complete information about prepared
statements"
Implement status variables for prepared statements commands (a port of
the patch by Andrey Hristov).
See details in comments to the changed files.
No test case as there is no way to test slow log/general log in
mysqltest.
mysql-test/r/ps_grant.result:
Now execute is logged with tag 'Execute' (changed result file).
sql/mysql_priv.h:
- remove obsolete macro.
- add declarations for new status variables.
- export function log_slow_statement, which now is used in sql_prepare.cc
sql/mysqld.cc:
Add status variables for prepared statements API: now we record
mysql_stmt_close, mysql_stmt_reset, mysql_stmt_prepare, mysql_stmt_execute
mysql_stmt_send_long_data, PREPARE, EXECUTE, DEALLOCATE.
sql/sql_parse.cc:
- account DEALLOCATE prepare as a Com_stmt_close command (close of a
prepared statement).
sql/sql_prepare.cc:
- fix a bug in SQL syntax for prepared statements + logging:
if we use --log and EXECUTE stmt USING @no_such_variable;, the
server crashed because the old code assumed that the variable
returned by get_var_with_binlog is never NULL.
- account statistics for
mysql_stmt_{prepare,execute,close,reset,send_long_data} in
Com_stmt_{prepare,execute,close,reset,send_long_data} correspondingly.
- log slow statements into the slow log early, when thd->query
points to a valid (with expanded placeholder values) query.
The previous version was logging it in sql_parse, when thd->query
is empty. Prevent the server from logging the statement twice by
setting thd->enable_slow_log= FALSE.
- now in case of EXECUTE stmt in SQL syntax for prepared statements the
general log gets two queries, e.g.
Query EXECUTE stmt USING @a, @b, @c
Execute INSERT INTO t1 VALUES (1, 2, 3)
This makes the behavior consistent with PREPARE command, which
also logs the statement twice.

CURSOR_TYPE_READ_ONLY". The bug was that we (me) don't perform proper
cleanups of the prepared statement when done fetching from a cursor.
Another patch.
sql/mysql_priv.h:
Rename reset_stmt_for_execute to init_stmt_before_use (to correspond to
cleanup_stmt_and_thd_after_use).
sql/sp_head.cc:
Rename.
sql/sql_prepare.cc:
Move common cleanup code to a cleanup function, call it when we close
a cursor.
sql/sql_select.cc:
Cleanup.
sql/sql_select.h:
No need for init_thd, this code has been inlined in Cursor::open.
tests/mysql_client_test.c:
Add a test case for Bug#10729 "mysql_stmt_attr_set CURSOR_TYPE_READ_ONLY"
(problem reusing a prepared statemnt if there was a cursor)
CURSOR_TYPE_READ_ONLY". The bug was that we (me) don't perform proper
cleanups of the prepared statement when done fetching from a cursor.
Another patch.
In order to make multi-delete SP friendly we need to have all table
locks for the elements of main statement table list properly set
at the end of parsing.
Also performed small cleanup: We don't need relink_tables_for_multidelete()
any longer since the only case now when TABLE_LIST::correspondent_table
is non-zero are tables in auxilary table list of multi-delete and these
tables are handled specially in mysql_multi_delete_prepare().
mysql-test/r/sp-threads.result:
Added test case for bug #11158 "Can't perform multi-delete in stored
procedure".
mysql-test/t/sp-threads.test:
Added test case for bug #11158 "Can't perform multi-delete in stored
procedure".
sql/mysql_priv.h:
- Removed third argument from the declaration of multi_delete_precheck()
as nowdays we calculate number of tables in multi-delete from which
we are going to delete rows right at the end of statement parsing.
- Introduced definition of multi_delete_set_locks_and_link_aux_tables()
which is responsible for propagation of proper table locks from
multi-delete's auxilary table list to the main list and binding
corresponding tables in these two lists.
sql/sql_base.cc:
Removed relink_tables_for_multidelete() routine and its invocations.
We don't need them in 5.0 since the only case now when
TABLE_LIST::correspondent_table is non-zero are tables in auxilary table
list of multi-delete and these tables are handled specially in
mysql_multi_delete_prepare().
sql/sql_lex.h:
LEX::table_count
Added description of new role of this LEX member for multi-delete.
Now for this statement we store number of tables from which we should
delete records there.
sql/sql_parse.cc:
multi_delete_precheck():
Moved code which is responsible for iterating through auxilary table
list and binding its elements with corresponding elements of main
table list, and properly updating locks in it to separate function -
multi_delete_set_locks_and_link_aux_tables(). This is because in order
to make multi-delete SP friendly we need to have all locks set properly
at the end of statement parsing. So we are introducing new function
which will be called from parser.
We also calculate number of tables from which we are going to perform
deletions there and store this number for later usage in
LEX::table_count.
Also removed some no longer needed code.
sql/sql_prepare.cc:
mysql_test_multidelete():
Now multi_delete_precheck() takes only two arguments, so we don't
need to pass fake third parameter.
sql/sql_yacc.yy:
delete:
In order to make multi-delete SP friendly we need to have all table
locks for the elements of main statement table list properly set
at the end of parsing.
