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/examples/ha_archive.cc: - extend the handlerton with the info about cursor behaviour at commit. sql/examples/ha_archive.h: - ctor moved to .cc to make use of archive handlerton sql/examples/ha_example.cc: - add handlerton instance, init handler::ht with it sql/examples/ha_example.h: - ctor moved to .cc to make use of ha_example handlerton sql/examples/ha_tina.cc: - add handlerton instance, init handler::ht with it sql/examples/ha_tina.h: - ctor moved to .cc to make use of CSV handlerton sql/ha_berkeley.cc: - init handlerton::flags and handler::ht sql/ha_berkeley.h: - ctor moved to .cc to make use of BerkeleyDB handlerton sql/ha_blackhole.cc: - add handlerton instance, init handler::ht with it sql/ha_blackhole.h: - ctor moved to .cc to make use of blackhole handlerton sql/ha_federated.cc: - add handlerton instance, init handler::ht with it sql/ha_federated.h: - ctor moved to .cc to make use of federated handlerton sql/ha_heap.cc: - add handlerton instance, init handler::ht with it sql/ha_heap.h: - ctor moved to .cc to make use of ha_heap handlerton sql/ha_innodb.cc: - init handlerton::flags and handler::ht of innobase storage engine sql/ha_innodb.h: - ctor moved to .cc to make use of archive handlerton sql/ha_myisam.cc: - add handlerton instance, init handler::ht with it sql/ha_myisam.h: - ctor moved to .cc to make use of MyISAM handlerton sql/ha_myisammrg.cc: - init handler::ht in the ctor sql/ha_myisammrg.h: - ctor moved to .cc to make use of MyISAM MERGE handlerton sql/ha_ndbcluster.cc: - init handlerton::flags and handler::ht sql/handler.cc: - drop support for ISAM storage engine, which was removed from 5.0 - close all "transient" cursors at COMMIT/ROLLBACK. A "transient" 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 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.

This patch allows to configure MyISAM for 128 indexes per table. The main problem is the key_map, wich is implemented as an ulonglong. To get rid of the limit and keep the efficient and flexible implementation, the highest bit is now used for all upper keys. This means that the lower keys can be disabled and enabled individually as usual and the high keys can only be disabled and enabled as a block. That way the existing test suite is still applicable, while more keys work, though slightly less efficient. To really get more than 64 keys, some defines need to be changed. Another patch will address this. include/my_bitmap.h: Bug#10932 - Building server with key limit of 128, makes test cases fail Added the declaration for a function that extends the highest bit value to all upper bits of a bigger bitmap. include/myisam.h: Bug#10932 - Building server with key limit of 128, makes test cases fail Changed MI_MAX_POSSIBLE_KEY to what it was meant for.

sql/log_event.cc: BUG#11567 - mysqlbinlog tests failing on Windows. Cast was not working as intended with Windows compiler, the value of option was being printed instead. Reason is that config-win.h has '#define bool BOOL', and on Windows BOOL is a typedef for int, which means that all casts to bool are really a cast to int. Changed to explicitly print a 1 or 0 instead of using cast.
