according to the standard. The idea is to use Field-classes to implement stored routines variables. Also, we should provide facade to Item-hierarchy by Item_field class (it is necessary, since SRVs take part in expressions). The patch fixes the following bugs: - BUG#8702: Stored Procedures: No Error/Warning shown for inappropriate data type matching; - BUG#8768: Functions: For any unsigned data type, -ve values can be passed and returned; - BUG#8769: Functions: For Int datatypes, out of range values can be passed and returned; - BUG#9078: STORED PROCDURE: Decimal digits are not displayed when we use DECIMAL datatype; - BUG#9572: Stored procedures: variable type declarations ignored;

The cause of the bug was the use of end_write_group instead of end_write in the case when ORDER BY required a temporary table, which didn't take into account the fact that loose index scan already computes the result of MIN/MAX aggregate functions (and performs grouping). The solution is to call end_write instead of end_write_group and to add the MIN/MAX functions to the list of regular functions so that their values are inserted into the temporary table. mysql-test/r/group_min_max.result: Test for BUG#14920 mysql-test/t/group_min_max.test: Test for BUG#14920 sql/sql_class.cc: Added new member to TMP_TABLE_PARAM. sql/sql_class.h: Added new member to TMP_TABLE_PARAM. sql/sql_select.cc: Enable result rows generated by loose index scan being written into a temporary table. The change is necessary because loose index scan already computes the result of GROUP BY and the MIN/MAX aggregate functions. This is realized by three changes: - create_tmp_table allocates space for aggregate functions in the list of regular functions, - use end_write instead of end_write group, - copy the pointers to the MIN/MAX aggregate functions to the list of regular functions TMP_TABLE_PARAM::items_to_copy. sql/sql_select.h: New parameter to create_tmp_table.

if inner routine has more local variables than outer one, and one of its last variables was used as argument to NOT operator". THD::spcont was non-0 when we were parsing stored routine/trigger definition during execution of another stored routine. This confused methods of Item_splocal and forced them use wrong runtime context. Fix ensures that we always have THD::spcont equal to zero during routine/trigger body parsing. This also allows to avoid problems with errors which occur during parsing and SQL exception handlers. mysql-test/r/sp.result: Test suite for bug#13549. mysql-test/r/trigger.result: Test suite for bug#13549. mysql-test/t/sp.test: Test suite for bug#13549. mysql-test/t/trigger.test: Test suite for bug#13549. sql/item.cc: Protection against using wrong context by SP local variable. sql/item.h: Protection against using wrong context by SP local variable. sql/protocol.cc: An incorrect macro name fixed. sql/protocol.h: An incorrect macro name fixed. sql/sp.cc: Do not allow SP which we are parsing to use other SP context (BUG#13549). sql/sp_head.cc: Protection against using wrong context by SP local variable. sql/sp_rcontext.h: Protection against using wrong context by SP local variable. sql/sql_cache.h: An incorrect macro name fixed. sql/sql_class.cc: Protection against using wrong context by SP local variable. sql/sql_class.h: Protection against using wrong context by SP local variable. sql/sql_trigger.cc: Do not allow Trigger which we are parsing to use other SP context (BUG#13549). sql/sql_yacc.yy: Protection against using wrong context by SP local variable.

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.

Version for 5.0. It fixes three problems: 1. The cause of the bug was that we did not check the table version for the HANDLER ... READ commands. We did not notice when a table was replaced by a new one. This can happen during ALTER TABLE, REPAIR TABLE, and OPTIMIZE TABLE (there might be more cases). I call the fix for this problem "the primary bug fix". 2. mysql_ha_flush() was not always called with a locked LOCK_open. Though the function comment clearly said it must. I changed the code so that the locking is done when required. I call the fix for this problem "the secondary fix". 3. In 5.0 (not in 4.1 or 4.0) DROP TABLE had a possible deadlock flaw in concur with FLUSH TABLES WITH READ LOCK. I call the fix for this problem "the 5.0 addendum fix". include/my_pthread.h: Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash Added a new macro for the 5.0 addendum fix. mysql-test/r/handler.result: Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash The test result. mysql-test/t/handler.test: Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash The test case. sql/lock.cc: Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash Changed a comment which did confuse me and which is not fully correct anymore after the 5.0 addendum fix. Added an assertion which would fire without the 5.0 addendum fix. sql/mysql_priv.h: Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash Changed a definition for the secondary fix. sql/sql_base.cc: Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash Changed function calls for the secondary fix. sql/sql_class.cc: Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash Changed a function call for the secondary fix. sql/sql_handler.cc: Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash The first two diffs make the primary bug fix. The rest is for the secondary fix. sql/sql_table.cc: Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash The first diff (four changed places) make the 5.0 addendum fix. The other three are changed function calls for the secondary fix.

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.

The idea of the patch is to separate statement processing logic, such as parsing, validation of the parsed tree, execution and cleanup, from global query processing logic, such as logging, resetting priorities of a thread, resetting stored procedure cache, resetting thread count of errors and warnings. This makes PREPARE and EXECUTE behave similarly to the rest of SQL statements and allows their use in stored procedures. This patch contains a change in behaviour: until recently for each SQL prepared statement command, 2 queries were written to the general log, e.g. [Query] prepare stmt from @stmt_text; [Prepare] select * from t1 <-- contents of @stmt_text The chagne was necessary to prevent [Prepare] commands from being written to the general log when executing a stored procedure with Dynamic SQL. We should consider whether the old behavior is preferrable and probably restore it. This patch refixes Bug#7115, Bug#10975 (partially), Bug#10605 (various bugs in Dynamic SQL reported before it was disabled). mysql-test/r/not_embedded_server.result: Since we don't want to log Dynamic SQL in stored procedures, now the general log gets only one log entry per SQL statement. mysql-test/r/sp-error.result: - remove obsolete tests - a better error message for the case when a stored procedure that returns a result set is called from a function mysql-test/r/trigger.result: - a better error message for the case when a stored procedure that returns a result set is called from a trigger mysql-test/t/sp-error.test: - a better error message for the case when a stored procedure that returns a result set is called from a function. - move the comment to its place (end of file). mysql-test/t/trigger.test: - a better error message for the case when a stored procedure that returns a result set is called from a trigger sql/item_func.cc: - we need to pass sql_command explicitly to get_var_with_binlog, because when creating a query for SQL prepared statement thd->lex->sql_command points at SQLCOM_EXECUTE, which is not listed in the list of update queries. sql/log_event.h: - remove an extra copy of the previous sentence sql/mysql_priv.h: - fix declarations of sql_prepare.cc API sql/share/errmsg.txt: - a new error message, when one attempts to execute a prepared statement which is currently being executed (this can happen only in Dynamic SQL at the moment). sql/sp_head.cc: - extend sp_multi_results_command to return different flags for a command (and rename it) - add support for SQLCOM_PREPARE,SQLCOM_EXECUTE, SQLCOM_DEALLOCATE to sp_get_flags_for_command - replace multiple boolean sp_head members with uint m_flags - a fix for a crash when user variables are used in a stored procedure and binlog is on. A temporary fix for Bug#12637 "SP crashes the server if it has update query with user var & binlog is enabled", which actually stands for stored functions: now instead of a crash we break replication if a user variable is used in a stored function which is executed in prelocked mode. sql/sp_head.h: - replace multiple boolean flags of sp_head with uint m_flags; - add flag CONTAINS_DYNAMIC_SQL - use this flag to error if a stored procedure with Dynamic SQL is called from a function or trigger. sql/sql_class.cc: - Statement_map::insert should not delete a statement if it exists, now it's done externally to be able to handle the case when the statement being deleted is in use. - remove extra code (free_list is already reset in free_items) sql/sql_lex.cc: - add lex->stmt_prepare_mode; we can't rely on thd->command any more, because we don't reset it any more (Dynamic SQL requirement is that PS are as little intrusive as possible). sql/sql_lex.h: - declare bool LEX::stmt_prepare_mode sql/sql_parse.cc: - move prepared statement code to sql_prepare.cc - change declarations (refactored code) - better error message when one attempts to use Dynamic SQL or a stored procedure that returns a result set in a function or trigger. sql/sql_prepare.cc: - major refactoring to ensure PREPARE/EXECUTE commands do not reset global THD state and allow their use in stored procedures. - add Prepared_statement::flags and use it to ensure no recursive execution of a prepared statement is possible - better comments sql/sql_yacc.yy: - enable PREPARE/EXECUTE/DEALLOCATE in stored procedures - produce an error message on attempt to use PREPARE/EXECUTE/DEALLOCATE in a stored function or trigger mysql-test/r/sp-dynamic.result: - sp-dynamic.test results mysql-test/t/sp-dynamic.test: - a new test for PREPARE/EXECUTE/DEALLOCATE in stored procedures.

Only one of them is active at any moment. - set_item_arena -> set_query_arena, because Item_arena was renamed to Query_arena a while ago - set_n_backup_item_arena -> set_n_backup_active_arena; the active arena is the arena thd->mem_root and thd->free_list are currently pointing at. - restore_backup_item_arena -> restore_active_arena (with the same rationale) - change_arena_if_needed -> activate_stmt_arena_if_needed; this method sets thd->stmt_arena active if it's not done yet. sql/item.cc: Rename. sql/item_cmpfunc.cc: Rename. sql/item_func.cc: Rename. sql/item_subselect.cc: Rename. sql/item_subselect.h: Remove an unused forward declaration. sql/item_sum.h: Remove an unused forward declaration. sql/mysql_priv.h: Remove an unused forward declaration. sql/sp.cc: Rename. sql/sp_head.cc: Rename. sql/sql_base.cc: Rename. sql/sql_class.cc: Rename. sql/sql_class.h: Rename. sql/sql_lex.cc: Rename. sql/sql_parse.cc: Rename. sql/sql_prepare.cc: Rename. sql/sql_select.cc: Rename. sql/sql_show.cc: Rename. sql/sql_union.cc: Rename. sql/sql_view.cc: Rename. sql/table.cc: Rename.

This allows us to use statement replication with functions and triggers The following things are fixed with this patch: - NOW() and automatic timestamps takes the value from the main event for functions and triggers (which allows these to replicate with statement level logging) - No side effects for triggers or functions with auto-increment values(), last_insert_id(), rand() or found_rows() - Triggers can't return result sets Fixes bugs: #12480: NOW() is not constant in a trigger #12481: Using NOW() in a stored function breaks statement based replication #12482: Triggers has side effects with auto_increment values #11587: trigger causes lost connection error mysql-test/r/trigger.result: Added test fpr big mysql-test/t/sp-error.test: Changed error message numbers mysql-test/t/trigger.test: Added test for trigger returning result (#11587) sql/item_func.cc: Store the first used seed value for RAND() value. (This makes rand() replicatable in functions and triggers) Save and clear run context before executing a stored function and restore it afterwards. This removes side effects of stored functions for RAND(), auto-increment values and NOW() and makes most stored function replicatable sql/share/errmsg.txt: Reuse error message also for triggers sql/sp_head.cc: If in function or trigger, don't change value of NOW() (This allows us to use statement replication with functions that directly or indirectly uses timestamps) sql/sql_class.cc: Added framework for storing and retrieving run context while exceuting triggers or stored functions. sql/sql_class.h: Added framework for storing and retrieving run context while exceuting triggers or stored functions. sql/sql_parse.cc: If in function or trigger, don't change value of NOW() (This allows us to use statement replication with functions that directly or indirectly uses timestamps) sql/sql_trigger.cc: Moved process_triggers function from sql_trigger.h Use reset/restore sub_statement_state while executing triggers to avoid side effects and make them replicatable sql/sql_trigger.h: Moved process_triggers function from sql_trigger.h Use reset/restore sub_statement_state while executing triggers to avoid side effects and make them replicatable sql/sql_yacc.yy: Give error message if trigger can return a result set (Bug #11587) tests/fork_big2.pl: Removed return from end of lines mysql-test/r/rpl_trigger.result: New BitKeeper file ``mysql-test/r/rpl_trigger.result'' mysql-test/t/rpl_trigger.test: New BitKeeper file ``mysql-test/t/rpl_trigger.test''

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.

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''

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: Added test for bug #11554 "Server crashes on statement indirectly using non-cached function". mysql-test/t/sp-error.test: 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/t/sp-threads.test: Added test for bug #11554 "Server crashes on statement indirectly using non-cached function". 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: Added error message saying that one cannot write-lock some of system tables with any other tables. sql/sp.cc: open_proc_table_for_read()/close_proc_table(): Added functions to be able open and close mysql.proc table when we already have some tables open and locked. open_proc_table_for_update(): Added function to simplify opening of mysql.proc for updates. 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: 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_lex.cc: Removed LEX::proc_table member which was not really used. sql/sql_lex.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).

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.
