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.

thd->allow_sum_func was left 'true' after previous statement thus allowing sum funcs to be present in conditions. thd->allow_sum_func should be set to 0 for each query and each prepared statement reinitialization. This is done in lex_start() and reset_stmt_for_execute(). sql/sql_lex.cc: Fix bug#13180 thd->allow_sum_func wasn't reset obefore query processing. thd->allow_sum_func is set to 0 in lex_start(). sql/sql_prepare.cc: Fix bug#13180 thd->allow_sum_func wasn't reset obefore query processing. thd->allow_sum_func is set to 0 in reset_stmt_for_execute(). mysql-test/t/update.test: Test case for bug#13180 thd->allow_sum_funcs wasn't reset before query processing. mysql-test/r/update.result: Test case for bug#13180 thd->allow_sum_funcs wasn't reset before query processing.

This bug occurs when some trigger for table used by DML statement is created or changed while statement was waiting in lock_tables(). In this situation prelocking set which we have calculated becames invalid which can easily lead to errors and even in some cases to crashes. With proposed patch we no longer silently reopen tables in lock_tables(), instead caller of lock_tables() becomes responsible for reopening tables and recalculation of prelocking set. mysql-test/t/trigger.test: Added tests for bug #12704 "Server crashes during trigger execution". Unfortunately these tests rely on the order in which tables are locked by statement so they are non-determenistic and therefore should be disabled. sql/lock.cc: mysql_lock_tables(): Now instead of always reopening altered or dropped tables by itself mysql_lock_tables() can notify upper level and rely on caller doing this. sql/mysql_priv.h: Now mysql_lock_tables() can either reopen deleted or altered tables by itself or notify caller about such situation through 'need_reopen' argument and rely on it in this. Also lock_tables() has new 'need_reopen' out parameter through which it notifies caller that some tables were altered or dropped so he needs to reopen them (and rebuild prelocking set some triggers may change or simply appear). sql/sp.cc: sp_add_used_routine(): To be able to restore LEX::sroutines_list to its state right after parsing we now adjust LEX::sroutines_list_own_last/sroutines_list_own_elements when we add directly used routine. sp_remove_not_own_routines(): Added procedure for restoring LEX::sroutines/sroutines_list to their state right after parsing (by throwing out non-directly used routines). sp_cache_routines_and_add_tables_for_view()/sp_update_stmt_used_routines(): We should use LEX::sroutines_list instead of LEX::sroutines as source of routines used by view, since LEX::sroutines is not availiable for view on second attempt to open it (see comment in open_tables() about it). sql/sp.h: sp_remove_not_own_routines(): Added procedure for restoring LEX::sroutines/sroutines_list to their state right after parsing (by throwing out non-directly used routines). sql/sp_head.cc: Removed assert which is no longer always true. sql/sql_base.cc: reopen_table(): When we re-open table and do shallow copy of TABLE object we should adjust pointers to it in associated Table_triggers_list object. Removed nil operation. open_tables(): Now this function is able to rebuild prelocking set for statement if it is needed. It also correctly handles FLUSH TABLES which may occur during its execution. lock_tables(): Instead of allowing mysql_lock_tables() to silently reopen altered or dropped tables let us notify caller and rely on that it will do reopen itself. This solves the problem when trigger suddenly appears or changed during mysq_lock_tables(). close_tables_for_reopen(): Added routine for properly preparing for reopening of tables and recalculation of set of prelocked tables. sql/sql_handler.cc: Here we let mysql_lock_tables() to reopen dropped or altered tables by itself. sql/sql_insert.cc: Here we let mysql_lock_tables() to reopen dropped or altered tables by itself. sql/sql_lex.cc: LEX: Added 'sroutines_list_own_last' and 'sroutines_list_own_elements' members which are used for keeping state in which 'sroutines_list' was right after statement parsing (and for restoring of this list to this state). sql/sql_lex.h: LEX: Added 'sroutines_list_own_last' and 'sroutines_list_own_elements' members which are used for keeping state in which 'sroutines_list' was right after statement parsing (and for restoring of this list to this state). Added chop_off_not_own_tables() method to simplify throwing away list of implicitly used (prelocked) tables. sql/sql_prepare.cc: Now instead of silently reopening altered or dropped tables in lock_tables() we notify caller and rely on that the caller will reopen tables. sql/sql_table.cc: Here we let mysql_lock_tables() to reopen dropped or altered tables by itself. sql/sql_trigger.cc: Added Table_triggers_list::set_table() method to adjust Table_triggers_list to new pointer to TABLE instance. sql/sql_trigger.h: Added Table_triggers_list::set_table() method to adjust Table_triggers_list to new pointer to TABLE instance. sql/sql_update.cc: Now instead of silently reopening altered or dropped tables in lock_tables() we notify caller and rely on that the caller will reopen tables.

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.

- current_arena to stmt_arena: the thread may have more than one 'current' arenas: one for runtime data, and one for the parsed tree of a statement. 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.

In cp932, '\' character can be the second byte in a multi-byte character stream. This makes it difficult to use mysql_escape_string. Added flag to indicate which languages allow '\' as second byte of multibyte sequence so that when putting a prepared statement into the binlog we can decide at runtime whether hex encoding is really needed. include/m_ctype.h: Added bool to indicate character sets which allow '\' as the second byte of a multibyte character set (currently only cp932). For these character sets, escaping with '\' is dangerous and leads to corruption in replication. include/my_sys.h: Add function to enocde a string as hex with no prefix (bare) mysys/charset.c: Add function to encode string as hex with no prefix (bare). sql/item.cc: Check the connection character set to see if escape_string_for_mysql is safe, or if character set requires unambiguous (hex) encoding sql/item.h: Pass thd to query_val_str for access to charset() sql/sql_prepare.cc: Pass thd to query_val_str. strings/ctype-big5.c: Add escape_with_backslash_is_dangerous flag. strings/ctype-bin.c: Add escape_with_backslash_is_dangerous flag strings/ctype-cp932.c: Add escape_with_backslash_is_dangerous flag. strings/ctype-czech.c: Add escape_with_backslash_is_dangerous flag. strings/ctype-euc_kr.c: Add escape_with_backslash_is_dangerous flag. strings/ctype-extra.c: Add escape_with_backslash_is_dangerous flag. strings/ctype-gb2312.c: Add escape_with_backslash_is_dangerous flag. strings/ctype-gbk.c: Added escape_with_backslash_is_dangerous flag. strings/ctype-latin1.c: Added escape_with_backslash_is_dangerous flag. strings/ctype-sjis.c: Added escape_with_backslash_is_dangerous flag. strings/ctype-tis620.c: Added esacpe_with_backslash_character_is_dangerous flag. strings/ctype-uca.c: Added escape_with_backslash_is_dangerous flag. strings/ctype-ucs2.c: Added escape_with_backslash_is_dangerous. strings/ctype-ujis.c: Added escape_with_backslash_is_dangerous flag. strings/ctype-utf8.c: Added escape_with_backslash_is_dangerous. strings/ctype-win1250ch.c: Added escape_with_backslash_is_dangerous.

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''

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.

main_mem_root is moved out of class Query_arena. sql/sp_head.cc: Adjust to the changed Query_arena constructor. main_mem_root is moved out of class Query_arena. sql/sp_head.h: main_mem_root is moved out of class Query_arena: add it to class sp_head. sql/sql_class.cc: main_mem_root is moved out of class Query_arena: remove constructors no longer relevant, remove dead code. sql/sql_class.h: main_mem_root is moved out of class Query_arena. sql/sql_prepare.cc: It's better to not use main_mem_root anywhere: logically, it's not a public member (can't fix sp_head::make_field and Item_subselect::exec to make it protected) sql/sql_select.cc: New Cursor constructor, which avoids unneeded memory allocation when initializign main_mem_root. sql/sql_select.h: main_mem_root is moved out of class Query_arena.
