Table definition cache, part 2
The table opening process now works the following way: - Create common TABLE_SHARE object - Read the .frm file and unpack it into the TABLE_SHARE object - Create a TABLE object based on the information in the TABLE_SHARE object and open a handler to the table object Other noteworthy changes: - In TABLE_SHARE the most common strings are now LEX_STRING's - Better error message when table is not found - Variable table_cache is now renamed 'table_open_cache' - New variable 'table_definition_cache' that is the number of table defintions that will be cached - strxnmov() calls are now fixed to avoid overflows - strxnmov() will now always add one end \0 to result - engine objects are now created with a TABLE_SHARE object instead of a TABLE object. - After creating a field object one must call field->init(table) before using it - For a busy system this change will give you: - Less memory usage for table object - Faster opening of tables (if it's has been in use or is in table definition cache) - Allow you to cache many table definitions objects - Faster drop of table mysql-test/mysql-test-run.sh: Fixed some problems with --gdb option Test both with socket and tcp/ip port that all old servers are killed mysql-test/r/flush_table.result: More tests with lock table with 2 threads + flush table mysql-test/r/information_schema.result: Removed old (now wrong) result mysql-test/r/innodb.result: Better error messages (thanks to TDC patch) mysql-test/r/merge.result: Extra flush table test mysql-test/r/ndb_bitfield.result: Better error messages (thanks to TDC patch) mysql-test/r/ndb_partition_error.result: Better error messages (thanks to TDC patch) mysql-test/r/query_cache.result: Remove tables left from old tests mysql-test/r/temp_table.result: Test truncate with temporary tables mysql-test/r/variables.result: Table_cache -> Table_open_cache mysql-test/t/flush_table.test: More tests with lock table with 2 threads + flush table mysql-test/t/merge.test: Extra flush table test mysql-test/t/multi_update.test: Added 'sleep' to make test predictable mysql-test/t/query_cache.test: Remove tables left from old tests mysql-test/t/temp_table.test: Test truncate with temporary tables mysql-test/t/variables.test: Table_cache -> Table_open_cache mysql-test/valgrind.supp: Remove warning that may happens becasue threads dies in different order mysys/hash.c: Fixed wrong DBUG_PRINT mysys/mf_dirname.c: More DBUG mysys/mf_pack.c: Better comment mysys/mf_tempdir.c: More DBUG Ensure that we call cleanup_dirname() on all temporary directory paths.

A fix and a test case for Bug#10760 and complementary cleanups.
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'' |
