unknown	f455634cba	Fix for bug #15047 : "server crash when compiling without transaction support". sql/sql_class.h: Fix for bug #15047: "server crash when compiling without transaction support". - set xid_state.xa_state to XA_NOTR in absence of transactional engines, as we check it in the end_trans() which is always called from the ha_enable_transaction().	20 years ago
unknown	11d4d7e6ff	Fix for bug #13825 "Triggers: crash if release savepoint" and for general handling of savepoints in stored routines. Fixed ha_rollback_to_savepoint()/ha_savepoint()/ha_release_savepoint() functions to properly handle savepoints inside of stored functions and triggers. Also now when we invoke stored function or trigger we create new savepoint level. We destroy it at the end of function/trigger execution and return back to old savepoint level. mysql-test/r/sp_trans.result: Added test for bug #13825 "Triggers: crash if release savepoint" and for general handling of savepoints in stored routines. mysql-test/t/sp_trans.test: Added test for bug #13825 "Triggers: crash if release savepoint" and for general handling of savepoints in stored routines. sql/ha_innodb.cc: innobase_savepoint(): Replaced check which always failed due to similar check in caller with assertion. sql/handler.cc: ha_rollback_to_savepoint()/ha_savepoint()/ha_release_savepoint(): Changed functions to properly support handling of savepoints inside of stored functions and triggers. sql/sql_class.cc: THD::reset_sub_statement_state()/restore_sub_statement_state(): When we invoke stored function or trigger we should create new savepoint level. We should destroy it at the end of function/trigger execution and return back to old savepoint level. To support this behavior we should save and reset list of current savepoints on entering function and restore old list when we leave it. sql/sql_class.h: Sub_statement_state: When we invoke stored function or trigger we should create new savepoint level. We should destroy it at the end of function/trigger execution and return back to old savepoint level. To support this behavior added "savepoint" member which is used to save/restore list of current savepoints on entering/leaving function. sql/sql_parse.cc: mysql_execute_command(): Changed processing of SQLCOM_SAVEPOINT so now it is not ignored when we are in autocommit mode and savepoint is set inside of stored function or trigger.	20 years ago

unknown	813fc4104e	A fix and a test case for Bug#6513 "Test Suite: Values inserted by using cursor is interpreted latin1 character and Bug#9819 "Cursors: Mysql Server Crash while fetching from table with 5 million records." A fix for a possible memory leak when fetching into an SP cursor in a long loop. The patch uses a common implementation of cursors in the binary protocol and in stored procedures and implements materialized cursors. For implementation details, see comments in sql_cursor.cc include/my_sys.h: - declaration for multi_alloc_root libmysqld/Makefile.am: - drop protocol_cursor.cc, add sql_cursor.cc (replaces the old implementation of cursors with a new one) mysql-test/r/ctype_ujis.result: - test results fixed (a test case for Bug#6513) mysql-test/r/sp-big.result: - test results fixed (a test case for Bug#9819) mysql-test/t/ctype_ujis.test: Add a test case for Bug#6513 "Test Suite: Values inserted by using cursor is interpreted latin1 character" mysql-test/t/sp-big.test: Add a restricted test case for Bug#9819 "Cursors: Mysql Server Crash while fetching from table with 5 million records." mysys/my_alloc.c: - an implementation of multi_alloc_root; this is largely a copy-paste from mulalloc.c, but the function is small and there is no easy way to reuse the existing C function. sql/Makefile.am: - add sql_cursor.h, sql_cursor.cc (a new implementation of stored procedure cursors) and drop protocol_cursor.cc (the old one) sql/handler.cc: - now TABLE object has its mem_root always initialized. Adjust the implementation handler::ha_open sql/item_subselect.cc: - adjust to the changed declaration of st_select_lex_unit::prepare sql/protocol.h: - drop Protocol_cursor sql/sp_head.cc: - move juggling with Query_arena::free_list and Item::next to sp_eval_func_item, as this is needed in 3 places already. sql/sp_head.h: - declare a no-op implementation for cleanup_stmt in sp_instr_cpush. This method is needed for non-materializing cursors, which are yet not used in stored procedures. - declaration for sp_eval_func_item sql/sp_rcontext.cc: - reimplement sp_cursor using the new implementation of server side cursors. - use sp_eval_func_item to assign values of SP variables from the row fetched from a cursor. This should fix a possible memory leak in the old implementation of sp_cursor::fetch sql/sp_rcontext.h: - reimplement sp_cursor using the new implementation of server side cursors. sql/sql_class.cc: - disable the functionality that closes transient cursors at commit/rollback; transient cursors are not used in 5.0, instead we use materialized ones. To be enabled in a later version. sql/sql_class.h: - adjust to the rename Cursor -> Server_side_cursor - additional declarations of select_union used in materialized cursors sql/sql_derived.cc: - reuse bits of tmp table code in UNION, derived tables, and materialized cursors - cleanup comments sql/sql_lex.h: - declarations of auxiliary methods used by materialized cursors - a cleanup in st_select_lex_unit interface sql/sql_list.h: - add an array operator new[] to class Sql_alloc sql/sql_prepare.cc: - split the tight coupling of cursors and prepared statements to reuse the same implementation in stored procedures - cleanups of error processing in Prepared_statement::{prepare,execute} sql/sql_select.cc: - move the implementation of sensitive (non-materializing) cursors to sql_cursor.cc - make temporary tables self-contained: the table, its record and fields are allocated in TABLE::mem_root. This implementation is not clean and resets thd->mem_root several times because of the way create_tmp_table works (many additional things are done inside it). - adjust to the changed declaration of st_select_lex_unit::prepare sql/sql_select.h: - move the declaration of sensitive (non-materializing) cursors to sql_cursor.cc sql/sql_union.cc: - move pieces of st_select_unit::prepare to select_union and st_table methods to be able to reuse code in the implementation of materialized cursors sql/sql_view.cc: - adjust to the changed signature of st_select_lex_unit::prepare sql/table.cc: - implement auxiliary st_table methods for use with temporary tables sql/table.h: - add declarations for auxiliary methods of st_table used to work with temporary tables tests/mysql_client_test.c: - if cursors are materialized, a parallel update of the table used in the cursor may go through: update the test. sql/sql_cursor.cc: New BitKeeper file ``sql/sql_cursor.cc'' -- implementation of server side cursors sql/sql_cursor.h: New BitKeeper file ``sql/sql_cursor.h'' - declarations for server side cursors.	20 years ago

unknown	39fda60043	Fix for bug #10055 "Using stored function with information_schema causes empty result set". 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 empty result set". mysql-test/t/information_schema.test: Added test which checks how information about current auto-increment value for table is reported in INFORMATION_SCHEMA.TABLES view. mysql-test/t/sp.test: Added test for bug #10055 "Using stored function with information_schema causes empty result set". 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(): 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/sql_class.cc: Open_tables_state, THD: 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. sql/sql_class.h: Open_tables_state, THD: 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. sql/sql_handler.cc: 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/sql_prepare.cc: 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/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(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them.	21 years ago

unknown	de6f5ae5ab	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=id2; -- blocked con2: update t1 set id=id2; -- 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''	21 years ago

unknown	11f9e513d7	Implementation of Monty's idea: Now we can open mysql.proc table for lookup 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.

unknown	91180cb8ab	- implement inheritance of sp_instr: public Query_arena. 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.	21 years ago
