Let us update "thd" pointer in LEX, all its units and in LEX::result before
executing statement in trigger body, since triggers are associated with TABLE
object and because of this can be used in different threads.
mysql-test/r/trigger.result:
Added test case for bug #11973 "SELECT .. INTO var_name; in trigger cause
crash on update".
mysql-test/t/trigger.test:
Added test case for bug #11973 "SELECT .. INTO var_name; in trigger cause
crash on update".
sql/item_subselect.cc:
subselect_engine:
Moved implementation of set_thd() method to item_subselect.cc,
since now it also sets "thd" for subselect_engine::result.
sql/item_subselect.h:
subselect_engine:
Moved implementation of set_thd() method to item_subselect.cc,
since now it also sets "thd" for subselect_engine::result.
sql/sql_class.h:
select_result:
Added set_thd() method for updating select_result::thd value (we need this
in cases when statement to which this select_result belongs will be used
in different threads, as it happens for statements in trigger body).
multi_delete/multi_update:
Got rid of redundant "thd" member (we already have it in select_result).
sql/sql_delete.cc:
multi_delete:
Got rid of redundant "thd" member (we already have it in select_result).
sql/sql_lex.h:
st_select_lex_unit:
Added set_thd() method for updating st_select_lex_unit::thd value
(we need this in cases when statement to which this unit belongs will
be used in different threads, as it happens for statements in trigger body).
We don't update thd of select_result pointed by st_select_lex_unit::result
in this method, since it is either have too short lifetime (i.e. created for
each execution) or is accessible via Item_subquery or LEX::result and thus
already taken care of.
sql/sql_parse.cc:
multi_delete:
Got rid of redundant "thd" member (we already have it in select_result).
sql/sql_prepare.cc:
reinit_stmt_before_use():

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

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():

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():

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.

Item_func_user now support both USER() and CURRENT_USER(), so we have to pass parametr what it is

on locking of mysql.proc table.
This allows to use stored routines safely under LOCK TABLES without explicitly
mentioning mysql.proc in the list of locked tables. It also fixes bug #11554
"Server crashes on statement indirectly using non-cached function".
mysql-test/r/sp-error.result:

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.

main_mem_root is moved out of class Query_arena.
sql/sp_head.cc:

main_mem_root is moved out of class Query_arena.
sql/sp_head.h:
main_mem_root is moved out of class Query_arena: add it to class sp_head.
sql/sql_class.cc:
main_mem_root is moved out of class Query_arena: remove
constructors no longer relevant, remove dead code.
sql/sql_class.h:
main_mem_root is moved out of class Query_arena.
sql/sql_prepare.cc:
It's better to not use main_mem_root anywhere: logically, it's not
a public member (can't fix sp_head::make_field and Item_subselect::exec
to make it protected)
sql/sql_select.cc:
New Cursor constructor, which avoids unneeded memory allocation
when initializign main_mem_root.
sql/sql_select.h:
main_mem_root is moved out of class Query_arena.
query transformations to the PREPARE stage (prepared statements).
sql/item.h:
Remove an unused friend declaration.
sql/mysql_priv.h:
Change signature of insert_fields()
sql/sp_head.cc:
Make is_stmt_prepare_or_first_sp_execute really work: reset SP state
to EXECUTED after execution.
sql/sql_base.cc:
allocate_view_names flag of insert_fields is removed.
The purpose of this variable was to amend the case when a view
is replaced with a base table between subsequent executions of a prepared
statement: in that case the new table theoretically can be used instead
of the view. If allocate_view_names was set,
all the references to the view expressions were replaced with Item_field's
which in turn could have been resolved by their names.
But this approach doesn't work for other reasons, so let's not try
to help what must be solved by TDC.
sql/sql_class.h:
Add is_first_sp_execute() helper method.
sql/sql_handler.cc:
insert_fields signature changed.
sql/sql_lex.h:
Add a comment for variable 'first_execution'.

ALTER, OPTIMIZE and ANALYZE statements".
In 4.1 we disabled logging of slow admin statements. The fix adds an
option to enable it back.
No test case (slow log is not tested in the test suite), but tested
manually.
+ post-review fixes (word police mainly).
sql/mysql_priv.h:
- declaration for a new option
sql/mysqld.cc:
Add server option '--log-slow-admin-statements' to log slow
optimize/alter/etc statements to the slow log if it's enabled.
Add warnings that this option works only if the slow log is open.
sql/sql_class.h:
Rename 'thd->slow_command' to thd->enable_slow_log (negates
the meaning of this variable, and so resolves the need to negate
value opt_log_slow_admin_statements when setting it).
sql/sql_parse.cc:
Implement optional logging of administrative statements in the slow log.

We should not allow explicit or implicit transaction commits inside
of stored functions or triggers (so in autocommit mode we should not
do commits after execution of sub-statement).
Also since we don't support nested statement transactions in 5.0,
we shouldn't commit or rollback stmt transactions while we are inside
stored functions or triggers. This should be fixed in later (>=5.1)
releases.
mysql-test/r/sp_trans.result:
Added test for bug #10015 "Crash in InnoDB if stored routines are used"
and for general transaction handling inside of functions.
mysql-test/t/sp_trans.test:
Added test for bug #10015 "Crash in InnoDB if stored routines are used"

sql/handler.cc:
ha_trans_commit()/ha_trans_rollback():
Since we don't support nested statement transactions in 5.0,
we can't commit or rollback stmt transactions while we are inside
stored functions or triggers. So we simply do nothing now.
This should be fixed in later ( >= 5.1) releases.
sql/item_func.cc:
Item_func_sp::execute():
Set THD::transaction.in_sub_stmt flag to TRUE during stored function
execution to prevent commits and rollbacks for statement level
transactions, since doing them will ruin such transaction for
stateemtn which calls this function.
sql/share/errmsg.txt:
Added error message which says that statements doing explicit or implicit
commits are disallowed in triggers and stored functions.
sql/sql_base.cc:
close_thread_tables():
Clarified comment about committing of statement transactions in
prelocked mode.
sql/sql_class.h:
THD::transaction:
Added in_sub_stmt method which indicates that we are executing
statements from trigger or stored function now, and thus
statement transaction belongs to statement which invoked this
routine and we should not commit or rollback it while executing
these sub-statements.
sql/sql_parse.cc:
end_active_trans()/begin_trans()/end_trans():
We should not commit or rollback global (non-stmt) transaction
if we are executing stored function or trigger. These checks will
catch situation when we are trying to do commit or rollback in stored
procedure which is called from function or trigger.
sql/sql_trigger.h:
Table_triggers_list::process_triggers():
Set THD::transaction.in_sub_stmt flag to TRUE during trigger
execution to prevent commits and rollbacks for statement level

Simplify Item_uint constructor by using the c-tor above.
sql/item_subselect.cc:
Now select_limit has type Item *.
We can safely create an Item in Item_exists_subselect::fix_length_and_dec():
it will be allocated in runtime memory root and freed in the end of
execution.
sql/sp_head.cc:
Add a special initalization state for stored procedures to
be able to easily distinguish the first execution of a stored procedure
from prepared statement prepare.
sql/sql_class.h:
Introduce new state 'INITIALIZED_FOR_SP' to be able to easily distinguish
the first execution of a stored procedure from prepared statement prepare.
sql/sql_derived.cc:
- use unit->set_limit() to set unit->select_limit_cnt, offset_limit_cnt
evreryplace. Add a warning about use of set_limit in
mysql_derived_filling.
sql/sql_error.cc:
- use unit->set_limit() to set unit->select_limit_cnt, offset_limit_cnt
evreryplace.
- this change is also aware of bug#11095 "show warnings limit 0 returns
all rows instead of zero rows", so the one who merges the bugfix from
4.1 can use local version of sql_error.cc.
sql/sql_handler.cc:
- use unit->set_limit() to initalize
unit->select_limit_cnt,offset_limit_cnt everyplace.
sql/sql_lex.cc:
Now ST_SELECT_LEX::select_limit, offset_limit have type Item *

- we can create an Item_int to set global limit of a statement:
it will be created in the runtime mem root and freed in the end of
execution.
sql/sql_repl.cc:
Use unit->set_limit to initialize limits.
sql/sql_select.cc:
- select_limit is now Item* so the proper way to check for default value
is to compare it with NULL.
sql/sql_union.cc:
Evaluate offset_limit_cnt using the new type of ST_SELECT_LEX::offset_limit
sql/sql_view.cc:
Now ST_SELECT_LEX::select_limit, offset_limit have type Item *
