result set".
To enable full access to contents of I_S tables from stored functions
or statements that use them, we manipulate with thread's open tables
state and ensure that we won't cause deadlock when we open tables by
ignoring flushes and name-locks.
Building of contents of I_S.TABLES no longer requires locking of tables
since we use use handler::info() method with HA_STATUS_AUTO flag instead
of handler::update_auto_increment() for obtaining information about
auto-increment values. But this also means that handlers have to implement
support for HA_STATUS_AUTO flag (particularly InnoDB needs it).
mysql-test/r/alter_table.result:
Updated test results. This change was caused by the fact that now when
we build contents of I_S tables (and thus output of SHOW INDEX) we
don't use instances of tables which may be already opened and locked
by thread (we always use new instance).
mysql-test/r/information_schema.result:
Added test which checks how information about current auto-increment value for
table is reported in INFORMATION_SCHEMA.TABLES view.
mysql-test/r/sp.result:
Added test for bug #10055 "Using stored function with information_schema causes
empty result set".

sql/mysql_priv.h:
close_thread_tables():
Get rid of 'stopper' argument which is no longer used. Now when we need
to open and then close some table without touching tables which are already
opened we use THD::reset_n/restore_backup_open_tables_state() methods.
open_tables()/open_normal_and_derived_tables():
Added 'flags' argument to be able open tables even if some has done
a flush or hold namelock on them.
sql/sp.cc:
close_proc_table/open_proc_table_for_read/db_find_routine():
Replaced push_open_tables_state/pop_open_tables_state() methods which
were saving/restoring current open tables state in/from THD::open_state_list
with reset_n_backup_open_tables_state/restore_backup_open_tables_state()
methods which assume that backup storage for this state is allocated on
stack (or elsewhere) by their caller.
open_proc_table_for_read():
Since now we can have several open tables states stacked up we can't rely
rely on checking whether we have some tables open in previous state.
Instead we always assume that some tables are open and we need to ignore
flush while locking mysql.proc. We don't really need
MYSQL_LOCK_IGNORE_GLOBAL_READ_LOCK in this case since we open mysql.proc table
only for reading.
sql/sp.h:
Added declarations of open_proc_table_for_read()/close_proc_table() to be
able to use them in sql_show.cc.
sql/sql_base.cc:
close_thread_tables():
Get rid of 'stopper' argument which is no longer used. Now when we need

Open_tables_state, THD:
Replaced push_open_tables_state/pop_open_tables_state() methods which

open_tables()/open_normal_and_derived_tables():
Added 'flags' argument to be able open tables even if some has done

sql/sql_show.cc:
get_all_tables():
Now we use THD::reset_n_/restore_backup_open_tables_state() for
saving/restoring open tables state instead of working with it directly
(This also allows us to have proper content of I_S system tables in
statements with stored functions and in stored functions). We also
ignore possible flushes when opening tables (we may create deadlock
otherwise). Also we do all needed manipulations with LEX in this function
and not in get_schema_tables_result() now.
get_schema_tables_record():
Let us use handler::info() method with HA_STATUS_AUTO flag for obtaining
information about table's auto-increment value. This allows to avoid locking
of tables which is needed when we use handler::update_auto_increment() method.
fill_schema_proc():
Now we use open_proc_table_for_read/close_proc_table() for access to
mysql.proc table (so we won't cause deadlock if we already have some
tables open and locked, this also allows us to have proper content in
ROUTINES system table in statements using stored functions/in stored
functions).
get_schema_tables_result():
Moved all manipulations with Open_tables_state and LEX needed for
safe opening of tables to ST_SCHEMA_TABLE::fill_table functions
(i.e. get_all_tables() and fill_schema_proc()).
sql/sql_update.cc:
open_tables()/open_normal_and_derived_tables():
Added 'flags' argument to be able open tables even if some has done
a flush or hold namelock on them.
Before the fix in ~Prepared_statments we got a memory leak when executing mysql_client_test.test
Note that test 'variables.test' fails.

The idea of the patch
is that every cursor gets its own lock id for table level locking.
Thus cursors are protected from updates performed within the same
connection. Additionally a list of transient (must be closed at
commit) cursors is maintained and all transient cursors are closed
when necessary. Lastly, this patch adds support for deadlock
timeouts to TLL locking when using cursors.
+ post-review fixes.
include/thr_lock.h:
- add a notion of lock owner to table level locking. When using
cursors, lock owner can not be identified by a thread id any more,
as we must protect cursors from updates issued within the same
connection (thread). So, each cursor has its own lock identifier to
use with table level locking.
- extend return values of thr_lock and thr_multi_lock with
THR_LOCK_TIMEOUT and THR_LOCK_DEADLOCK, since these conditions
are now possible (see comments to thr_lock.c)
mysys/thr_lock.c:
Better support for cursors:
- use THR_LOCK_OWNER * as lock identifier, not pthread_t.
- check and return an error for a trivial deadlock case, when an
update statement is issued to a table locked by a cursor which has
been previously opened in the same connection.
- add support for locking timeouts: with use of cursors, trivial
deadlocks can occur. For now the only remedy is the lock wait timeout,
which is initialized from a new global variable 'table_lock_wait_timeout'
Example of a deadlock (assuming the storage engine does not downgrade
locks):
con1: open cursor for select * from t1;
con2: open cursor for select * from t2;
con1: update t2 set id=id*2; -- blocked
con2: update t1 set id=id*2; -- deadlock
Lock timeouts are active only if a connection is using cursors.
- the check in the wait_for_lock loop has been changed from
data->cond != cond to data->cond != 0. data->cond is zeroed
in every place it's changed.
- added comments

SQL level cursor is a cursor that uses tables that have a transaction-
specific state.
sql/handler.h:
- extend struct handlerton with flags, add handlerton *ht to every
handler instance.
sql/lock.cc:
- extend mysql_lock_tables to send error to the client if
thr_multi_lock returns a timeout or a deadlock error.

sql/set_var.cc:
- add new global variable 'table_lock_wait_timeout' to specify
a wait timeout for table-level locks of MySQL (in seconds). The default
timeout is 50 seconds. The timeout is active only if the connection
has open cursors.
sql/sql_class.cc:
- implement Statement_map::close_transient_cursors
- safety suggests that we need an assert ensuring
llock_info->n_cursors is functioning properly, adjust destruction of
the Statement_map to allow such assert in THD::~THD
sql/sql_class.h:
- add support for Cursors registry to Statement map.
sql/sql_prepare.cc:
- maintain a list of cursors that must be closed at commit/rollback.
sql/sql_select.cc:
- extend class Cursor to support specific at-COMMIT/ROLLBACK behavior.
If a cursor uses tables of a storage engine that
invalidates all open tables at COMMIT/ROLLBACK, it must be closed
before COMMIT/ROLLBACK is executed.
sql/sql_select.h:
- add an own lock_id and commit/rollback status flag to class Cursor
tests/mysql_client_test.c:
A test case for Bug#10760 and complementary issues: test a simple
deadlock case too.

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:
- changed the principle of Query_arena::backup_arena; free_items is now
a member of Query_arena.
sql/sql_prepare.cc:
free_items() is now a member of Query_arena.
sql/sql_select.cc:
free_items() now automatically sets free_list to zero.
sql/sql_class.cc:
Statement constructor for the case when it's used for backup only
was removed.
sql/sql_class.h:
Remove THD::stmt_backup and simplify Statement constructors.
sql/sql_prepare.cc:

sql/sql_select.cc:
Use an object on stack instead of THD::stmt_backup

to make it protected)

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)
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.
sql/sql_prepare.cc:
Cleanup mysql_test_* family of calls: now we don't send error message
from mysql_stmt_prepare, so no need to support -1 return code
(meaning error is not sent to client) in these functions.
Move unit->cleanup() to mysql_stmt_prepare() as it's done in most
of the mysql_test_ functions, and is a no-op for those which don't
call unit->prepare(). This should make fixing of Bug#10729 (cursors)
easier.
don't evaluate subqueries during statement prepare, even if they
are not correlated.
With post-review fixes.
sql/mysql_priv.h:
Add UNCACHEABLE_PREPARE to mark subqueries as non-constant in
mysql_stmt_prepare
sql/sql_lex.cc:
Add a missing assert: noone can call unit::set_limit from
mysql_stmt_prepare.
sql/sql_lex.h:
Comment fixed.
sql/sql_parse.cc:
Mark new SELECT_LEXes as uncacheable if they created during
statement prepare.
sql/sql_prepare.cc:
Switch off the uncacheable flag when prepare is done.

(crash on attempt to re-execute a statement with an open cursor) +
post-review fixes.
include/errmsg.h:
Add a special error message when we attempt to mysql_stmt_fetch
from a statement which has no result set.
libmysql/errmsg.c:
Error message text for CR_NO_RESULT_SET
libmysql/libmysql.c:
Move the code which frees result sets on client and closes the cursor
on server, resets long data state on client and server.
This makes one function out of two (mysql_stmt_reset and
mysql_stmt_free_result), thus aggregating all related reset work
in one place.
sql-common/client.c:
Fix one place where we flushed the pending result set of a statement,
but didn't set unbuffered_fetch_cancelled flag.
sql/share/errmsg.txt:
Fix format of ER_UNKNOWN_STMT_HANDLER error message (needs to
be fixed separately in 4.1). Add two new error messages
for the case when we fetch from when there is no cursor
and for the case when we attempt to execute a statement while there is
a cursor.
sql/sql_prepare.cc:
Return error when we fetch while there is no open cursor and
when we call execute while there is a pending cursor.
Fix mysql_stmt_reset to close the open cursor if there is any.
sql/sql_select.cc:
free_items and free_root moved to Cursor::close().
sql/sql_select.h:
A comment added.
tests/mysql_client_test.c:

with cursor". The patch refactors do_select/sub_select

Pushing with view.test failing (--ps-protocol).
sql/sql_prepare.cc:
Cursor::fetch() now returns void
sql/sql_select.cc:
A fix for Bug#9520 "SELECT DISTINCT crashes server with cursor":
* rename sub_select returns codes to be able to track down what's going
on in which case.
* move record processing and outer join record processing to a separate
function, out of sub_select read-record loop.
* use generalized sub_select() nested loop function for
cursors instead of own loop implementation used in Cursor::fetch() before
sql/sql_select.h:

for execution of next chunk of cursor's rows.
tests/mysql_client_test.c:
A test case for Bug#9520 "SELECT DISTINCT crashes server with cursor"
New more SP-locking friendly approach to handling locks in multi-update.
Now we mark all tables of multi-update as needing write lock at parsing
stage and if possible downgrade lock at execution stage (For its work
SP-locking mechanism needs to know all lock types right after parsing
stage).
mysql-test/r/sp-threads.result:

SP_TABLE, sp_head::merge_table_list()/add_used_tables_to_table_list():
Since some queries during their execution (e.g. multi-update)
may change type of lock for some of their tables and thus change
lock_type member for some of elements of table list, we should
store type of lock in SP_TABLE struct explicitly instead of using
lock_type member of TABLE_LIST object pointed by SP_TABLE::table.
sql/sql_lex.h:
Removed no longer used LEX::multi_lock_option member.
sql/sql_prepare.cc:
mysql_test_update():
We don't need to bother about LEX::multi_lock_option if we convert
multi-update to update anymore. Since nowdays multi-update uses
TABLE_LIST::lock_type for specifying lock level of updated tables
instead of LEX::multi_lock_option.
sql/sql_update.cc:
mysql_update()/mysql_multi_update_prepare():
Now we mark all tables of multi-update as needing write lock at parsing

SP-locking (For its work SP-locking mechanism needs to know all lock
