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.

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.
mysql-test/var:
New BitKeeper file ``mysql-test/var''
"Triggers have the wrong namespace"
"Triggers: duplicate names allowed"
"Triggers: CREATE TRIGGER does not accept fully qualified names"
"SHOW TRIGGERS"
mysql-test/r/information_schema.result:
Added tests for new INFORMATION_SCHEMA.TRIGGERS view and SHOW TRIGGERS command.
mysql-test/r/information_schema_db.result:
INFORMATION_SCHEMA.TRIGGERS view was added.
mysql-test/r/rpl_sp.result:
Now DROP TRIGGER interprets first part of trigger identifier as database
name and not as table name. Adjusted tests properly.
mysql-test/r/trigger.result:
Now DROP TRIGGER interprets first part of trigger identifier as database
name and not as table name. Adjusted tests properly.
Added test checking that triggers have database wide namespace.
Added test for bug #8791 "Triggers: Allowed to create triggers on a subject
table in a different DB".
mysql-test/r/view.result:
Now DROP TRIGGER interprets first part of trigger identifier as database
name and not as table name. Adjusted tests properly.
mysql-test/t/information_schema.test:
Added tests for new INFORMATION_SCHEMA.TRIGGERS view and SHOW TRIGGERS command.
mysql-test/t/rpl_sp.test:
Now DROP TRIGGER interprets first part of trigger identifier as database
name and not as table name. Adjusted tests properly.
mysql-test/t/trigger.test:
Now DROP TRIGGER interprets first part of trigger identifier as database
name and not as table name. Adjusted tests properly.
Added test checking that triggers have database wide namespace.
Added test for bug #8791 "Triggers: Allowed to create triggers on a subject
table in a different DB".
mysql-test/t/view.test:
Now DROP TRIGGER interprets first part of trigger identifier as database
name and not as table name. Adjusted tests properly.
sql/handler.cc:
Added .TRN tho the list of known file extensions assoicated with tables.
sql/item.h:
trg_action_time_type/trg_event_type enums:
Added TRG_ACTION_MAX/TRG_EVENT_MAX elements which should be used instead of
magical values in various loops where we iterate through all types of trigger
action times or/and trigger event types.
sql/lex.h:
Added new symbol "TRIGGERS".
sql/mysql_priv.h:
Added declaration of constant holding extension for trigger name (.TRN) files.
sql/mysqld.cc:
Added statistical variable for SHOW TRIGGERS command.
sql/share/errmsg.txt:
Added error message saying that one attempts to create trigger in wrong schema.
sql/sp.cc:
Replaced magical values with TRG_EVENT_MAX/TRG_ACTION_MAX constants.
sql/sql_base.cc:
open_unireg_entry():
Now Table_triggers_list::check_n_load() has one more argument which
controls whether we should prepare Table_triggers_list with fully functional
triggers or load only their names.
sql/sql_lex.h:
Added element for new SHOW TRIGGERS command to enum_sql_command enum.
sql/sql_parse.cc:
prepare_schema_table():
Added support for SHOW TRIGGERS statement.
sql/sql_show.cc:
Added new INFORMATION_SCHEMA.TRIGGERS view and SHOW TRIGGERS command.
sql/sql_table.cc:
mysql_rm_table_part2():
Replaced simple deletion of .TRG file with call to
Table_triggers_list::drop_all_triggers which will also delete .TRN files
for all triggers associated with table.
sql/sql_trigger.cc:
Now triggers have database wide namespace. To support it we create special .TRN
file with same name as trigger for each trigger. This file contains name of
trigger's table so one does not need to specify it explicitly in DROP TRIGGER.
Moreover DROP TRIGGER treats first part of trigger identifier as database name
now. Updated mysql_create_or_drop_trigger() routine and
Table_triggers_list::create_trigger()/drop_trigger()/check_n_load() methods
accordingly. Added add_table_for_trigger() routine and
Table_triggers_list::drop_all_triggers() method.
Added Table_triggers_list::get_trigger_info() for obtaining trigger metadata.
sql/sql_trigger.h:
Table_triggers_list:
Use TRG_EVENT_MAX, TRG_ACTION_MAX instead of magic values.
Added get_trigger_info() method for obtaining trigger's meta-data.
Added drop_all_triggers() method which drops all triggers for table.
Added declarations of trg_action_time_type_names/trg_event_type_names
arrays which hold names of triggers action time types and event types.
sql/sql_yacc.yy:
Changed grammar for CREATE/DROP TRIGGER to support database wide trigger
namespace. Added new SHOW TRIGGERS statement.
sql/table.h:
enum enum_schema_tables:
Added constant for new INFORMATION_SCHEMA.TRIGGERS view.

Return 0 if table exists and it could be created
Return >0 if table existed but it could not be created.
sql/sql_base.cc:
Only need to call ha_create_table_from_engine and check if result is > 0. If that is the case, print error message
- Added better error messages when trying to open a table that can't be discovered or unpacked. The most likely cause of this is that it does not have any frm data, probably since it has been created from NdbApi or is a NDB system table.
- Separated functionality that was in ha_create_table_from_engine into two functions. One that checks if the table exists and another one that tries to create the table from the engine.
mysql-test/r/ndb_autodiscover.result:
Add tests for reading from a table that can't be discovered(SYSTAB_0)
Discovery is not performed during create table anymore.
mysql-test/t/ndb_autodiscover.test:

sql/handler.h:

Rename ha_table_exists to ha_table_exists_in_engine
sql/sql_base.cc:
Use the function ha_table_exists_in_engine to detect if table exists in enegine.
If it exists, call function ha_create_table_from_engine to try and create it.
If create of table fails, set correct error message.
sql/sql_table.cc:
Add comments, remove parameter create_if_found to ha_create_table_from_engine.
When dropping a table, try to discover it from engine. If discover fails, use same error message as if the table didn't exists.
Maybe another message should be displayed here, ex: "Table could not be dropped, unpack failed"
When creating a new table, use ha_table_exists_in_engine to check if a table with the given name already exists.
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"
and for general transaction handling inside of functions.
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
transactions, since doing them will ruin such transaction for
stateemtn which invokes this trigger.
sql/sql_yacc.yy:
Prohibited usage of statements which do explicit or implicit commit or
rollback inside of stored functions and triggers.

Semi-synchronous replication for InnoDB type tables; before telling the client that a commit has been processed, wait that the replication thread has returned from my_net_send() where it sends the binlog to the slave; note that TCP/IP, even with the TCP_NODELAY option does not guarantee that the slave has RECEIVED the data - this is just heuristic at the moment; this is useful in failover: in almost all cases, every transaction that has returned from the commit has been sent and processed in the slave, which makes failover to the slave simpler if the master crashes; the code does not work yet as is, because MySQL should call innobase_report_binlog_offset_and_commit() in a commit; we will most probably return that call to 5.0.x, to make InnoDB Hot Backup and group commit to work again; XA code broke them temporarily in 5.0.3
