This bug occurs when some trigger for table used by DML statement is created
or changed while statement was waiting in lock_tables(). In this situation
prelocking set which we have calculated becames invalid which can easily lead
to errors and even in some cases to crashes.
With proposed patch we no longer silently reopen tables in lock_tables(),
instead caller of lock_tables() becomes responsible for reopening tables and
recalculation of prelocking set.
mysql-test/t/trigger.test:
Added tests for bug #12704 "Server crashes during trigger execution".
Unfortunately these tests rely on the order in which tables are locked
by statement so they are non-determenistic and therefore should be disabled.
sql/lock.cc:
mysql_lock_tables():
Now instead of always reopening altered or dropped tables by itself
mysql_lock_tables() can notify upper level and rely on caller doing this.
sql/mysql_priv.h:
Now mysql_lock_tables() can either reopen deleted or altered tables by itself
or notify caller about such situation through 'need_reopen' argument and rely
on it in this.
Also lock_tables() has new 'need_reopen' out parameter through which it
notifies caller that some tables were altered or dropped so he needs to reopen
them (and rebuild prelocking set some triggers may change or simply appear).
sql/sp.cc:
sp_add_used_routine():
To be able to restore LEX::sroutines_list to its state right after parsing
we now adjust LEX::sroutines_list_own_last/sroutines_list_own_elements when
we add directly used routine.
sp_remove_not_own_routines():
Added procedure for restoring LEX::sroutines/sroutines_list to their state
right after parsing (by throwing out non-directly used routines).
sp_cache_routines_and_add_tables_for_view()/sp_update_stmt_used_routines():
We should use LEX::sroutines_list instead of LEX::sroutines as source of
routines used by view, since LEX::sroutines is not availiable for view
on second attempt to open it (see comment in open_tables() about it).
sql/sp.h:
sp_remove_not_own_routines():
Added procedure for restoring LEX::sroutines/sroutines_list to their state
right after parsing (by throwing out non-directly used routines).
sql/sp_head.cc:
Removed assert which is no longer always true.
sql/sql_base.cc:
reopen_table():
When we re-open table and do shallow copy of TABLE object we should adjust
pointers to it in associated Table_triggers_list object. Removed nil
operation.
open_tables():
Now this function is able to rebuild prelocking set for statement if it is
needed. It also correctly handles FLUSH TABLES which may occur during its
execution.
lock_tables():
Instead of allowing mysql_lock_tables() to silently reopen altered or dropped
tables let us notify caller and rely on that it will do reopen itself.
This solves the problem when trigger suddenly appears or changed during
mysq_lock_tables().
close_tables_for_reopen():
Added routine for properly preparing for reopening of tables and recalculation
of set of prelocked tables.
sql/sql_handler.cc:
Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_insert.cc:
Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_lex.cc:
LEX:
Added 'sroutines_list_own_last' and 'sroutines_list_own_elements' members
which are used for keeping state in which 'sroutines_list' was right after
statement parsing (and for restoring of this list to this state).
sql/sql_lex.h:
LEX:
Added 'sroutines_list_own_last' and 'sroutines_list_own_elements' members
which are used for keeping state in which 'sroutines_list' was right after
statement parsing (and for restoring of this list to this state).
Added chop_off_not_own_tables() method to simplify throwing away list
of implicitly used (prelocked) tables.
sql/sql_prepare.cc:
Now instead of silently reopening altered or dropped tables in
lock_tables() we notify caller and rely on that the caller will
reopen tables.
sql/sql_table.cc:
Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_trigger.cc:
Added Table_triggers_list::set_table() method to adjust Table_triggers_list
to new pointer to TABLE instance.
sql/sql_trigger.h:
Added Table_triggers_list::set_table() method to adjust Table_triggers_list
to new pointer to TABLE instance.
sql/sql_update.cc:
Now instead of silently reopening altered or dropped tables in
lock_tables() we notify caller and rely on that the caller will
reopen tables.

Bug was introduced by cset 1.1659.14.1. Before it server was silently
ignoring that lock can't be acquired because it already acquired.
This patch makes make_global_read_lock_block_commit() return without error
if lock already acquired.

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.

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/mysqld.cc:
- add server option --table_lock_wait_timeout (in seconds)
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

of stored routines definitions even if we already have some tables open and
locked. To avoid deadlocks in this case we have to put certain restrictions
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:
Added test which checks that now we can read stored routines definitions
under LOCK TABLES even if we have not locked mysql.proc explicitly. Also
added check for restrictions which this ability puts on mysql.proc locking.
Updated test for bug #9566 to correspond this new situation.
mysql-test/r/sp-threads.result:

sql/lock.cc:
get_lock_data():
To be able to open and lock for reading system tables like 'mysql.proc',
when we already have some tables opened and locked, and avoid deadlocks
we have to disallow write-locking of these tables with any other tables.
sql/mysql_priv.h:
open_table() has new parameter which allows to open table even if some-one
has done a flush or holding namelock on it.
sql/share/errmsg.txt:

db_find_routine_aux()/db_find_routine()/db_update_routine()/...
Moved responsibility for opening mysql.proc table from db_find_routine_aux()
one level up, since this level knows better which type of table access for
reading of for update it needs.
sp_function_exists():
Removed unused function.
sql/sp.h:
sp_function_exists():
Removed unused function.
sql/sql_base.cc:
open_table():
Added new parameter which allows to open table even if some-one has done a
flush or holding namelock on it.
open_unireg_entry():
Mark 'mysql.proc' as a system table which has special restrictions on its
locking, but thanks to them can be open and locked even if we already have
some open and locked.
sql/sql_class.cc:
Moved THD members holding information about open and locked tables to separate
Open_tables_state class to be able to save/restore this state easier.
Added THD::push_open_tables_state()/pop_open_tables_state() methods for
saving/restoring this state.
sql/sql_class.h:

Removed LEX::proc_table member which was not really used.
sql/sql_table.cc:
open_table() has new parameter which allows to open table even if some-one
has done a flush or holding namelock on it.
sql/table.h:
Added TABLE_SHARE::system_table indicating that this table is system table
like 'mysql.proc' and we want to be able to open and read-lock it even when
we already have some tables open and locked (and because of this we have
to put some restrictions on write locking it).

1.) Added a new option to mysql_lock_tables() for ignoring FLUSH TABLES.
Used the new option in create_table_from_items().
It is necessary to prevent the SELECT table from being reopend.
It would get new storage assigned for its fields, while the
SELECT part of the command would still use the old (freed) storage.
2.) Protected the CREATE TABLE and CREATE TABLE ... SELECT commands
against a global read lock. This prevents a deadlock in
CREATE TABLE ... SELECT in conjunction with FLUSH TABLES WITH READ LOCK
and avoids the creation of new tables during a global read lock.
3.) Replaced set_protect_against_global_read_lock() and
unset_protect_against_global_read_lock() by
wait_if_global_read_lock() and start_waiting_global_read_lock()
in the INSERT DELAYED handling.

Added and extended some comments.
Added a protection against global read lock while a handler is
created and initialized.
Moved the unlock of the delayed insert object past its last usage
in delayed_get_table().
Changed the table locking in handle_delayed_insert() so that it
does not wait for global read lock.

Split TABLE to TABLE and TABLE_SHARE (TABLE_SHARE is still allocated as part of table, will be fixed soon)
Created Field::make_field() and made Field_num::make_field() to call this
Added 'TABLE_SHARE->db' that points to database name; Changed all usage of table_cache_key as database name to use this instead
Changed field->table_name to point to pointer to alias. This allows us to change alias for a table by just updating one pointer.

hadn't incremented it => very wrong => hangs.

Keep old code
when one connection had done FLUSH TABLES WITH READ LOCK, some updates, and then COMMIT,
it was accepted but my_error() was called and so, while client got no error, error was logged in binlog.
We now don't call my_error() in this case; we assume the connection know what it does.
This problem was specific to 4.0.21. The change is needed to make replication work with existing versions of innobackup.
sql/lock.cc:
If a connection has done FLUSH TABLES WITH READ LOCK and now is doing COMMIT, don't give error
(applies only if it's the same connection; others' COMMITs are still blocked).
(Includes merge of arena code in 4.1 and 5.0)

And a test.
sql/handler.cc:
making COMMIT wait if FLUSH TABLES WITH READ LOCK happened.
sql/lock.cc:
an additional stage so that FLUSH TABLES WITH READ LOCK blocks COMMIT:
make_global_read_lock_block_commit():
taking the global read lock is TWO steps (2nd step is optional; without
it, COMMIT of existing transactions will be allowed):
lock_global_read_lock() THEN make_global_read_lock_block_commit().
sql/mysql_priv.h:
new argument to wait_if_global_read_lock()
sql/sql_class.h:
THD::global_read_lock now an uint to reflect the 2 steps of global read lock (does not block COMMIT / does)
sql/sql_db.cc:
update for new prototype
sql/sql_parse.cc:
implementing the two steps of global read lock so that FLUSH TABLES WITH READ LOCK can block COMMIT without deadlocking with COMMITs.

Bug #4810 "deadlock with KILL when the victim was in a wait state"
(I included mutex unlock into exit_cond() for future safety)
and BUG#4827 "KILL while START SLAVE may lead to replication slave crash"
sql/lock.cc:
we did exit_cond() before unlock(LOCK_open), which led to deadlocks with THD::awake(). Fixing this.
sql/log.cc:
mutex unlock is now included in exit_cond()
sql/repl_failsafe.cc:
we did exit_cond() before unlock(LOCK_rpl_status), which led to deadlocks with THD::awake(). Fixing this.
sql/slave.cc:
we did exit_cond() before unlock(cond_lock), which led to deadlocks with THD::awake(). Fixing this.
Fixing also that if killed while waiting for slave thread to start, we don't release the mutex
(that caused a double release of the mutex => crash).
sql/sql_class.h:
comments about exit_cond()/enter_cond().
Mutex unlock is now included in exit_cond() so that it's always done in the good order.
sql/sql_table.cc:
unlock is now included in exit_cond().
