unknown	d5303b8ab8	Fix for bug #12704 "Server crashes during trigger execution". 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.	21 years ago
unknown	c910050a76	Implement WL#2661 "Prepared Statements: Dynamic SQL in Stored Procedures". 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.	21 years ago
unknown	dc92221300	Rename: - 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.	21 years ago

unknown	7517d7e112	Implementation of WL#2486 - "Process NATURAL and USING joins according to SQL:2003". * Some of the main problems fixed by the patch: - in "select " queries the expanded correctly according to ANSI for arbitrary natural/using joins - natural/using joins are correctly transformed into JOIN ... ON for any number/nesting of the joins. - column references are correctly resolved against natural joins of any nesting and combined with arbitrary other joins. * This patch also contains a fix for name resolution of items inside the ON condition of JOIN ... ON - in this case items must be resolved only against the JOIN operands. To support such 'local' name resolution, the patch introduces a stack of name resolution contexts used at parse time.

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.

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.

unknown	14b1f91ba4	Enable support of access to tables from triggers. Thus fix bug #8406 "Triggers crash if referencing a table" and several other related bugs. Fix for bug #11834 "Re-execution of prepared statement with dropped function crashes server." which was spotted during work on previous bugs. Also couple of nice cleanups: - Replaced two separate hashes for stored routines used by statement with one. - Now instead of doing one pass through all routines used in statement for caching them and then doing another pass for adding their tables to table list, we do only one pass during which do both things. mysql-test/r/sp-error.result: Added test for bug #11834 "Re-execution of prepared statement with dropped function crashes server" also covering handling of prepared statements which use stored functions but does not require prelocking. mysql-test/r/sp.result: Updated test for LOCK TABLES with views in table list. (Old version of statement used in this test will work ok now, since prelocking algorithm was tuned and will lock only one multi-set of tables for each routine even if this routine is used in several different views). mysql-test/r/trigger.result: Added several tests for triggers using tables. mysql-test/t/sp-error.test: Added test for bug #11834 "Re-execution of prepared statement with dropped function crashes server" also covering handling of prepared statements which use stored functions but does not require prelocking. mysql-test/t/sp.test: Updated comment about recursive views to reflect current situation. Updated test for LOCK TABLES with views in table list. (Old version of statement used in this test will work ok now, since prelocking algorithm was tuned and will lock only one multi-set of tables for each routine even if this routine is used in several different views). mysql-test/t/trigger.test: Added several tests for triggers using tables. sql/item_func.cc: Item_func_sp::cleanup(): By next statement execution stored function can be dropped or altered so we can't assume that sp_head object for it will be still valid. sql/sp.cc: - Added Sroutine_hash_entry structure that represents element in the set of stored routines used by statement or routine. We can't as before use LEX_STRING for this purprose because we want link all elements of this set in list. - Replaced sp_add_to_hash() with sp_add_used_routine() which takes into account that now we use one hash for stored routines used by statement instead of two and which mantains list linking all elelemnts in this hash. - Renamed sp_merge_hash() to sp_update_sp_used_routines(). - Introduced sp_update_stmt_used_routines() for adding elements to the set of routines used by statement from another similar set for statement or routine. This function will also mantain list linking elements of destination set. - Now instead of one sp_cache_routines() function we have family of sp_cache_routines_and_add_tables() functions which are also responsible for adding tables used by routines being cached to statement table list. Nice optimization - thanks to list linking all elements in the hash of routines used by statement we don't need to perform several iterations over this hash (as it was before in cases when we have added new elements to it). sql/sp.h: Added declarations of functions used for manipulations with set (hash) of stored routines used by statement. sql/sp_head.cc: sp_name::init_qname(): Now sp_name also holds key identifying routine in the set (hash) of stored routines used by statement. sp_head: Instead of two separate hashes sp_funs/m_spprocs representing sets of stored routines used by this routine we use one hash - m_sroutines. sp_instr_set_trigger_field: Added support for subqueries in assignments to row accessors in triggers. Removed definition of sp_add_sp_tables_to_table_list() and auxilary functions since now we don't have separate stage on which we add tables used by routines used by statement to table list for prelocking. We do it on the same stage as we load those routines in SP cache. So all this functionality moved to sp_cache_routines_and_add_tables() family of functions. sql/sp_head.h: sp_name: Now this class also holds key identifying routine in the set (hash) of stored routines used by statement. sp_head: Instead of two separate hashes sp_funs/m_spprocs representing sets of stored routines used by this routine we use one hash - m_sroutines. sp_instr_set_trigger_field: Added support for subqueries in assignments to row accessors in triggers. Removed declaration of sp_add_sp_tables_to_table_list() since now we don't have separate stage on which we add tables used by routines used by statement to table list for prelocking. We do it on the same stage as we load those routines in SP cache. sql/sql_base.cc: open_tables(): - LEX::spfuns/spprocs hashes were replaced with one LEX::sroutines hash. - Now instead of doing one pass through all routines used in statement for caching them and then doing another pass for adding their tables to table list, we do only one pass during which do both things. It is easy to do since all routines in the set of routines used by statement are linked in the list. This also allows us to calculate table list for prelocking more precisely. - Now triggers properly inform prelocking algorithm about tables they use. sql/sql_lex.cc: lex_start(): Replaced LEX::spfuns/spprocs with with one LEX::sroutines hash. Added LEX::sroutines_list list linking all elements in this hash. st_lex::st_lex(): Moved definition of LEX constructor to sql_lex.cc file to be able use sp_sroutine_key declaration from sp.h in it. sql/sql_lex.h: LEX: Replaced two separate hashes for stored routines used by statement with one. Added list linking all elements in this hash to be able to iterate through all elements and add new elements to this hash at the same time. Moved constructor definition to sql_lex.cc. sql/sql_parse.cc: mysql_execute_command(): Replaced LEX::spfuns/spprocs with one LEX::sroutines hash. sql/sql_trigger.cc: Added missing GNU GPL notice. Table_triggers_list::check_n_load() Added initialization of sroutines_key which stores key representing triggers of this table in the set (hash) of routines used by this statement. sql/sql_trigger.h: Added missing GNU GPL notice. Table_triggers_list: Added sroutines_key member to store key representing triggers of this table in the set (hash) of routines used by this statement. Declared sp_cache_routines_and_add_tables_for_triggers() as friend since it needs access to sroutines_key and trigger bodies. sql/sql_yacc.yy: - Now we use sp_add_used_routine() instead of sp_add_to_hash() for adding elements to the set of stored routines used in statement. - Enabled support of subqueries as right sides in assignments to triggers' row accessors.	21 years ago

The patch adds grammar support for LIMIT ?, ? and changes the type of ST_SELECT_LEX::select_limit,offset_limit from ha_rows to Item, so that it can point to Item_param. mysql-test/include/ps_modify.inc: Fix existing tests: now LIMIT can contain placeholders. mysql-test/include/ps_query.inc: Fix existing tests: now LIMIT can contain placeholders. mysql-test/r/ps.result: Add basic test coverage for LIMIT ?, ? and fix test results. mysql-test/r/ps_2myisam.result: Fix test results: now LIMIT can contain placeholders. mysql-test/r/ps_3innodb.result: Fix test results: now LIMIT can contain placeholders. mysql-test/r/ps_4heap.result: Fix test results: now LIMIT can contain placeholders. mysql-test/r/ps_5merge.result: Fix test results: now LIMIT can contain placeholders. mysql-test/r/ps_6bdb.result: Fix test results: now LIMIT can contain placeholders. mysql-test/r/ps_7ndb.result: Fix test results: now LIMIT can contain placeholders. mysql-test/t/ps.test: Add basic test coverage for LIMIT ?, ?. sql/item.h: Add a short-cut for (ulonglong) val_int() to Item. Add a constructor to Item_int() that accepts ulonglong. Simplify Item_uint constructor by using the c-tor above. sql/item_subselect.cc: Now select_limit has type Item . We can safely create an Item in Item_exists_subselect::fix_length_and_dec(): it will be allocated in runtime memory root and freed in the end of execution. sql/sp_head.cc: Add a special initalization state for stored procedures to be able to easily distinguish the first execution of a stored procedure from prepared statement prepare. sql/sql_class.h: Introduce new state 'INITIALIZED_FOR_SP' to be able to easily distinguish the first execution of a stored procedure from prepared statement prepare. sql/sql_derived.cc: - use unit->set_limit() to set unit->select_limit_cnt, offset_limit_cnt evreryplace. Add a warning about use of set_limit in mysql_derived_filling. sql/sql_error.cc: - use unit->set_limit() to set unit->select_limit_cnt, offset_limit_cnt evreryplace. - this change is also aware of bug#11095 "show warnings limit 0 returns all rows instead of zero rows", so the one who merges the bugfix from 4.1 can use local version of sql_error.cc. sql/sql_handler.cc: - use unit->set_limit() to initalize unit->select_limit_cnt,offset_limit_cnt everyplace. sql/sql_lex.cc: Now ST_SELECT_LEX::select_limit, offset_limit have type Item * sql/sql_lex.h: Now ST_SELECT_LEX::select_limit, offset_limit have type Item * sql/sql_parse.cc: - use unit->set_limit() to initalize unit->select_limit_cnt,offset_limit_cnt everyplace. - we can create an Item_int to set global limit of a statement: it will be created in the runtime mem root and freed in the end of execution. sql/sql_repl.cc: Use unit->set_limit to initialize limits. sql/sql_select.cc: - select_limit is now Item* so the proper way to check for default value is to compare it with NULL. sql/sql_union.cc: Evaluate offset_limit_cnt using the new type of ST_SELECT_LEX::offset_limit sql/sql_view.cc: Now ST_SELECT_LEX::select_limit, offset_limit have type Item * sql/sql_yacc.yy: Add grammar support for LIMIT ?, ? clause.	21 years ago
unknown	78422442df	Preparatory (and the most problematic) patch for Bug#7306 "the server side preparedStatement error for LIMIT placeholder", which moves all uses of LIMIT clause from PREPARE to OPTIMIZE and later steps. After-review fixes. mysql-test/r/group_min_max.result: Test results fixed for EXPLAINs when using GROUP_MIN_MAX access plan. sql/item_subselect.cc: Move setting of the internal LIMIT used for IN/ALL/ANY/EXISTS subqueries to one place: Item_exists_subselect::fix_length_and_dec(). This implies that unit->select_limit_cnt is not set until the item is fixed. This is OK, as now LIMIT values are not used until JOIN::optimize. sql/mysql_priv.h: setup_tables no longer needs a special flag for the case when it's called from JOIN::reinit() (we don't need to call setup_tables between two executions of a correlated subquery). sql/opt_range.cc: Fix a glitch in GROUP_MIN_MAX access plan: we should use table metadata, not field data, to evaluate max_used_key_length, which is then used for explain. sql/sp.cc: - setup_tables signature changed. sql/sql_base.cc: - setup_tables no longer needs a special mode for subqueries. Unused checks were removed. sql/sql_delete.cc: - setup_tables signature changed sql/sql_help.cc: - setup_tables signature changed sql/sql_insert.cc: - setup_tables signature changed sql/sql_lex.cc: Consolidate setting of internal LIMIT for IN/ALL/ANY/EXISTS subqeries in one place, and hence remove it from st_select_lex::test_limit(). sql/sql_lex.h: Cleanup signature of st_select_lex_unit::init_prepare_fake_select_lex(). sql/sql_load.cc: - setup_tables signature changed sql/sql_olap.cc: - setup_tables signature changed sql/sql_parse.cc: - st_select_lex_unit::set_limit() signature changed sql/sql_select.cc: Move setting of JOIN::select_limit from JOIN::prepare to JOIN::optimize. At prepare, limit is unknown yet. Remove excessive cleanups from JOIN::reinit which were overwriting join->join_tab[i]->table->used_keys. This fixes the bug which was triggered by the change in item_subselect.cc. sql/sql_union.cc: Class st_select_lex_unit was changed to avoid calls to st_select_lex_unit::set_limit from places where it may be unknown. Now unit->select_limit_cnt is set at ::exec(). st_select_lex_unit::init_prepare_fake_select_lex(): - move out set_limit functionality - remove a few lines of dead code. st_select_lex_unit::prepare(): - now we don't call set_limit at the time of prepare, so the value of unit->select_limit_cnt may be unknown here. Use sl->select_limit instead. st_select_lex_unit::exec(): - cleanup - call set_limit explicitly as it has been moved out of init_prepare_fake_select_lex. sql/sql_update.cc: - setup_tables signature changed	21 years ago

unknown	ac9f68b9fa	Better approach for prelocking of tables for stored routines execution and some SP-related cleanups. - We don't have separate stage for calculation of list of tables to be prelocked and doing implicit LOCK/UNLOCK any more. Instead we calculate this list at open_tables() and do implicit LOCK in lock_tables() (and UNLOCK in close_thread_tables()). Also now we support cases when same table (with same alias) is used several times in the same query in SP. - Cleaned up execution of SP. Moved all common code which handles LEX and does preparations before statement execution or complex expression evaluation to auxilary sp_lex_keeper class. Now all statements in SP (and corresponding instructions) that evaluate expression which can contain subquery have their own LEX. mysql-test/r/lock.result: Replaced wrong error code with the correct one after fixing bug in SP-locking. mysql-test/r/mysqldump.result: Added dropping of view which is used in test to its beginning. mysql-test/r/sp.result: Added tests for improved SP-locking.

Now its 2nd parameter is in/out since it can add elements to table list. sql/sp.cc: sp_find_procedure(): Added one more parameter which enforces cache only lookup. sp_merge_hash(): Now uses its return value to indicate that first of two hashes changed as result of merge. sp_cache_routines(): This function caches all stored routines used in query now. sql/sp.h: - sp_find_procedure() now has one more parameter which enforces cache only lookup. - sp_merge_hash() now uses its return value to indicate that first of two hashes changed as result of merge. - sp_cache_routines() caches all stored routines now. So it does not need third argument any more. sql/sp_head.cc: sp_head::sp_head(): Added initialization of new m_spfuns and m_spprocs members. sp_head::execute(): Let us save/restore part of thread context which can be damaged by execution of instructions. sp_head::execute_function()/execute_procedure(): Now it is responsibility of caller to close tables used in subqueries which are passed as routine parameters. sp_head::restore_lex(): Let us accumulate information about routines used by this one in new m_spfuns, m_spprocs hashes. sp_lex_keeper::reset_lex_and_exec_core() Main method of new auxilary sp_lex_keeper class to which instructions delegate responsibility for handling LEX and preparations before executing statement or calculating complex expression. Since all instructions which calculate complex expression or execute command now use sp_lex_keeper they have to implement sp_instr::exec_core() method. Most of instruction specific logic has moved from sp_instr::execute() to this new method. Removed sp_instr_set_user_var class which is no longer used, because nowdays we allow execution of statements in stored functions and triggers. sp_merge_table_list() became sp_head::merge_table_list() method. It also treats sp_head::m_sptabs as multi-set of tables now. sp_hash_to_table_list() became sp_head::add_used_tables_to_table_list(). It takes into account that sp_head::m_sptabs is multi-set and allocates object into persistent arena of PS. Removed sp_merge_table_hash(), sp_open_and_lock_tables(), sp_unlock_tables(), sp_merge_routine_tables() methods since they are not used by new prelocking mechanism. Added sp_add_sp_tables_to_table_list() which serves for adding tables needed by routines used in query to the query table list for prelocking. sql/sp_head.h: class sp_head: - Added m_spfuns, m_spprocs members for storing names of routines used by this routine. - Added add_used_tables_to_table_list() method which allows to add tables needed by this routine to query's table list. - Converted sp_merge_table_list() to sp_head::merge_table_list() method. - Changed semantics of THD::m_sptabs. Now it is multi-set which contains only tables which are used by this routine and not routines that are called from this one. Removed sp_merge_routine_tables(), sp_merge_table_hash(), sp_open_and_lock_tables(), sp_unlock_tables() calls since they are not used for our prelocking list calculation. Added auxilary sp_lex_keeper class to which instructions delegate responsibility for handling LEX and preparations before executing statement or calculating complex expression. This class uses new sp_instr::exec_core() method which is responsible for executing instruction's core function after all preparations were made. All instructions which hold and calculate complex expression now have their own LEX (by aggregating sp_lex_keeper instance). sp_instr_stmt now uses sp_lex_keeper too. Removed sp_instr_set_user_var class which is no longer used, because nowdays we allow execution of statements in stored functions and triggers. sql/sp_rcontext.cc: Now sp_cursor holds pointer to sp_lex_keeper instead of LEX. sql/sp_rcontext.h: Now sp_cursor holds pointer to sp_lex_keeper instead of LEX. sql/sql_acl.cc: acl_init(), grant_init(): Now we use simple_open_n_lock_tables() instead of explicit calls to open_tables() and mysql_lock_tables(). sql/sql_base.cc: Implemented support for execution of statements in "prelocked" mode. When we have statement which uses stored routines explicitly or implicitly (via views or triggers) we have to open and lock all tables for these routines at the same time as tables for the main statement. In fact we have to do implicit LOCK TABLES at the begining of such statement and implict UNLOCK TABLES at its end. We call such mode "prelocked". When open_tables() is called for the statement tables which are needed for execution of routines used by it are added to its tables list (this process also caches all routines used). Implicit use of routines is discovered when we open view or table with trigger and apropriate tables are added to the table list at this moment. Statement which has such extra tables in its list (well actually any that uses functions) is marked as requiring prelocked mode for its execution. When lock_tables() sees such statement it will issue implicit LOCK TABLES for this extended table list instead of doing usual locking, it will also set THD::prelocked_mode to indicate that we are in prelocked mode. When open_tables()/lock_tables() are called for statement of stored routine (substatement), they notice that we are running in prelocked mode and use one of prelocked tables from those that are not used by upper levels of execution. close_thread_tables() for substatement won't really close tables used but will mark them as free for reuse instead. Finally when close_thread_tables() is called for the main statement it really unlocks and closes all tables used. Everything will work even if one uses such statement under real LOCK TABLES (we are simply not doing implicit LOCK/UNLOCK in this case). sql/sql_class.cc: Added initialization of THD::prelocked_mode member. sql/sql_class.h: - Added prelocked_mode_type enum and THD::prelocked_mode member which are used for indication whenever "prelocked mode" is on (i.e. that statement uses stored routines and is executed under implicit LOCK TABLES). - Removed THD::shortcut_make_view which is no longer needed. We use TABLE_LIST::prelocking_placeholder for the same purprose now. sql/sql_handler.cc: Changed open_tables() invocation. Now its 2nd parameter is in/out since it can add elements to table list. sql/sql_lex.cc: lex_start(): Added initialization of LEX::query_tables_own_last. Unused LEX::sptabs member was removed. st_lex::unlink_first_table()/link_first_table_back(): We should update LEX::query_tables_last properly if table list contains(ed) only one element. sql/sql_lex.h: LEX: - Removed sptabs member since it is no longer used. - Added query_tables_own_last member, which if non-0 indicates that statement requires prelocking (implicit LOCK TABLES) for its execution and points to last own element in query table list. If it is zero then this query does not need prelocking. - Added requires_prelocking(), mark_as_requiring_prelocking(), first_not_own_table() inline methods to incapsulate and simplify usage of this new member. sql/sql_parse.cc: dispatch_command(): To properly leave prelocked mode when needed we should call close_thread_tables() even if there are no open tables. mysql_execute_command(): - Removed part of function which were responsible for doing implicit LOCK TABLES before statement execution if statement used stored routines (and doing UNLOCK TABLES at the end). Now we do all this in open_tables()/lock_tables()/close_thread_tables() instead. - It is also sensible to reset errors before execution of statement which uses routines. - SQLCOM_DO, SQLCOM_SET_OPTION, SQLCOM_CALL We should always try to open tables because even if statement has empty table list, it can call routines using tables, which should be preopened before statement execution. - SQLCOM_CALL We should not look up routine called in mysql.proc, since it should be already cached by this moment by open_tables() call. - SQLCOM_LOCK_TABLES it is better to use simple_open_n_lock_tables() since we want to avoid materialization of derived tables for this command. sql/sql_prepare.cc: mysql_test_update(): Changed open_tables() invocations. Now its 2nd parameter is in/out since it can add elements to table list. check_prepared_statement(): Since now we cache all routines used by statement in open_tables() we don't need to do it explicitly. mysql_stmt_prepare(): Now we should call close_thread_tables() when THD::lex points to the LEX of statement which opened tables. reset_stmt_for_execute(): Commented why we are resetting all tables in table list. sql/sql_trigger.h: Table_triggers_list::process_triggers(): We should surpress sending of ok packet when we are calling trigger's routine, since now we allow statements in them. sql/sql_update.cc: Changed open_tables() invocations. Now its 2nd parameter is in/out since it can add elements to table list. sql/sql_view.cc: mysql_make_view(): - Removed handling of routines used in view. Instead we add tables which are needed for their execution to statement's table list in open_tables(). - Now we use TABLE_LIST::prelocking_placeholder instead of THD::shortcut_make_view for indicating that view is opened only to discover which tables and routines it uses (this happens when we build extended table list for prelocking). Also now we try to avoid to modify main LEX in this case (except of its table list). - Corrected small error we added tables to the table list of the main LEX without updating its query_tables_last member properly. sql/sql_yacc.yy: Now each expression which is used in SP statements and can contain subquery has its own LEX. This LEX is stored in corresponding sp_instr object and used along with Item tree for expression calculation. We don't need sp_instr_set_user_var() anymore since now we allow execution of statements in stored functions and triggers. sql/table.h: Added TABLE_LIST::prelocking_placeholder member for distinguishing elements of table list which does not belong to the statement itself and added there only for prelocking (as they are to be used by routines called by this statement). sql/tztime.cc: my_tz_init(): Now we use more simplier simple_open_n_lock_tables() call instead of open_tables()/lock_tables() pair.	21 years ago

unknown	3f24932124	WL#2130: Table locking for stored FUNCTIONs Collect all tables and SPs refered by a statement, and open all tables with an implicit LOCK TABLES. Do find things refered by triggers and views, we open them first (and then repeat this until nothing new is found), before doing the actual lock tables. mysql-test/r/information_schema.result: Updated result for WL#2130. mysql-test/r/lock.result: Updated result for WL#2130. mysql-test/r/sp-error.result: Updated result for WL#2130. mysql-test/r/sp.result: Updated result for WL#2130. mysql-test/r/view.result: Updated result for WL#2130. mysql-test/t/information_schema.test: Disabled one test case due to a bug involving LOCK TABLES, which shows up with WL#2130. mysql-test/t/lock.test: New error message with WL#2130. This change is under debate and might change in the future, but will do for now. mysql-test/t/sp-error.test: Updated for WL#2130. Some tests are voided when table access does work from functions. mysql-test/t/sp.test: Updated for WL#2130. mysql-test/t/view.test: Updated for WL#2130. sql/item_func.cc: We now have to set net.no_send_ok for functions too, with WL#2130. sql/share/errmsg.txt: Reused an error code since the old use was voided by WL#2130, but a new one was needed instead (similar, but more specific restriction). sql/sp.cc: Fixed error handling and collection of used tables for WL#2130. sql/sp.h: Fixed error handling and collection of used tables for WL#2130. sql/sp_head.cc: Added support functions for collecting and merging hash tables and lists of used tables from SPs and substatements, for WL#2130. sql/sp_head.h: Added support functions for collecting and merging hash tables and lists of used tables from SPs and substatements, for WL#2130. sql/sql_base.cc: Changed the way table->query_id is tested and set during with locked tables in effect. This makes some SP test cases work with WL#2130, but has a side effect on some error cases with explicit LOCK TABLES. It's still debated if this is the correct way, so it might change. sql/sql_class.h: Added flags for circumventing some interference between WL#2130 and mysql_make_view(). sql/sql_derived.cc: Added some missing initializations. (Potential bugs.) sql/sql_lex.cc: Clear the new hash tables for WL#2130. sql/sql_lex.h: Added hash tables for procedures and tables too (as for functions), for WL#2130. sql/sql_parse.cc: WL#2130: Make table accesses from stored functions work by adding an implicit LOCK TABLES around (most) executed statements. To do this, we have to go through a loop where we collect all SPs and tables in mysql_execute_statement. sql/sql_prepare.cc: Cache both functions and procedures for WL#2130. sql/sql_show.cc: Added some missing initializations. (Potential bugs.) sql/sql_view.cc: Shortcut mysql_make_view() if thd->shortcut_make_view is true during the pre-open phase for collecting tables in WL#2130. Otherwise, the similar mechanism here causes interference. sql/sql_yacc.yy: For WL#2130, added caching of procedures and disallowed LOCK/UNLOCK TABLES in SPs.	21 years ago

unknown	20bd0bd6fd	Fix for bug #7899 "CREATE TABLE .. SELECT .. and CONVERT_TZ() function does not work well together". Now using simplier and more correct implementation of st_lex::unlink_first_table()/link_first_table_back() (It also nicely handles case when global table list is created because of implictly used time zone tables). (2nd attempt) Fix for bug #7705 "CONVERT_TZ() crashes with subquery/WHERE on index column". Implemented new approach for caching objects for constant time zone arguments. Now instead of determining whenever these arguments are constants and performing time zone lookup at fix_fields() stage, we do it on first get_date() invocation. Cleanup of global @@time_zone variable handling. mysql-test/r/timezone2.result: Added test for bugs #7705 "CONVERT_TZ() crashes with subquery/WHERE on index column" and #7899 "CREATE TABLE .. SELECT .. and CONVERT_TZ() function does not work well together". mysql-test/t/timezone2.test: Added test for bugs #7705 "CONVERT_TZ() crashes with subquery/WHERE on index column" and #7899 "CREATE TABLE .. SELECT .. and CONVERT_TZ() function does not work well together". sql/item_timefunc.cc: Item_func_convert_tz(): New approach for caching objects for constant time zone arguments. Now instead of determining whenever these arguments are constants and performing time zone lookup at fix_fields() stage, we do it on first get_date() invocation. This works better in cases when const_item() for these arguments returns true only on get_date() stage but not on fix_fields() stage (e.g. this happens in quries with joins or derived tables). sql/item_timefunc.h: Item_func_convert_tz(): Added from_tz_cached/to_tz_cached members indicating whenever we already have Time_zone object representing one of constant time zone arguments. sql/set_var.cc: Cleaned up global @@time_zone variable handling. Now we use proper locking when we are setting or reading its value. sql/set_var.h: Removed declaration of sys_var_thd_time_zone::get_tz_ptr() method, which no longer used. sql/sql_lex.cc: st_lex::unlink_first_table(), st_lex::link_first_table_back(): Simplify implementation according to Monty's suggestion. Instead doing something special if global and local table lists are the same, we simply save/restore pointers to first elements of both global and local lists (which works even when this lists are the same!). This handles nicely the case when we have separate global table list becuase time zone tables are implicitly used. sql/tztime.cc: Backport of Monty's fixes from 5.0, which give us nicer error messages if we haven't found time zone with such name or its description.	21 years ago
