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.

Implementation of WL#2897: Complete definer support in the stored routines. The idea is to add DEFINER-clause in CREATE PROCEDURE and CREATE FUNCTION statements. Almost all support of definer in stored routines had been already done before this patch. NOTE: this patch changes behaviour of dumping stored routines in mysqldump. Before this patch, mysqldump did not dump DEFINER-clause for stored routines and this was documented behaviour. In order to get full information about stored routines, one should have dumped mysql.proc table. This patch changes this behaviour, so that DEFINER-clause is dumped. Since DEFINER-clause is not supported in CREATE PROCEDURE | FUNCTION statements before this patch, the clause is covered by additional version-specific comments. client/mysqldump.c: Updated the code for dumping stored routines: cover DEFINER-clause into version-specific comment. mysql-test/r/gis.result: Updated result file after adding DEFINER-clause. mysql-test/r/information_schema.result: Updated result file after adding DEFINER-clause. mysql-test/r/mysqldump.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_ddl.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_sp.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_trigger.result: Updated result file after adding DEFINER-clause. mysql-test/r/sp-security.result: Updated result file after adding DEFINER-clause. mysql-test/r/sp.result: Updated result file after adding DEFINER-clause. mysql-test/r/sql_mode.result: Updated result file after adding DEFINER-clause. mysql-test/t/sp-security.test: Updated result file after adding DEFINER-clause. sql/sp.cc: Added DEFINER-clause. sql/sp_head.cc: Added a new convenient variant of set_definer() operation. sql/sp_head.h: Updated result file after adding DEFINER-clause. sql/sql_lex.h: Renamed trigger_definition_begin into stmt_definition_begin to be used for triggers and stored routines. sql/sql_parse.cc: Check DEFINER-clause. sql/sql_trigger.cc: Renamed trigger_definition_begin into stmt_definition_begin to be used for triggers and stored routines. sql/sql_yacc.yy: Added DEFINER-clause.

Approximative fixes for BUG#2610,2611,9100 i.e. WL#2146 binlogging/replication of routines (stored procs and functions). Approximative, because it's using our binlogging way (what we call "query"-level) and this is not as good as record-level binlog (5.1) would be. It imposes several limitations to routines, and has caveats (which I'll document, and for which the server will try to issue errors but that is not always possible). Reason I don't propagate caller info to the binlog as planned is that on master and slave users may be different; even with that some caveats would remain. mysql-test/mysql-test-run.sh: In the testsuite we know what we do, we are not creating nasty routines, and breaking binlog is ok except in rpl_sp. mysql-test/r/blackhole.result: Updating results now that 4.1 has been merged mysql-test/valgrind.supp: Some suppressions for Valgrind (useful on my machine Suse 9.1); this is just adding to the already existing suppressions of pthread and dl. sql/item_func.cc: Don't binlog the substatements when executing a function. If the function is declared to modify data and does not complete, warning "broken binlog". Note that SELECT myfunc() will not be binlogged even if myfunc() updates data (will be documented); but INSERT INTO t VALUES(myfunc()) will be binlogged (what decides is if the caller gets binlogged; the function changes nothing to binlogging). sql/log_event.cc: Just making functions which can be re-used when we binlog more strings in status_vars in Query_log_event (e.g. one day "user", "host"). sql/log_event.h: comment sql/mysql_priv.h: --log-bin-trust-routine-creators sql/mysqld.cc: --log-bin-trust-routine-creators sql/set_var.cc: --log-bin-trust-routine-creators sql/share/errmsg.txt: error messages to warn about problems with routines and binlog sql/slave.cc: If in a routine, replication table inclusion/exclusion rules always answer "replicate!" (see comment in code). sql/sp.cc: If binlog is on: errors if one wants to create a non-deterministic update routine (repeatability problem - note that the test is not perfect for functions) or does not have SUPER (because routines can easily be made to destroy slave's data with just CREATE ROUTINE and EXECUTE priv on master). --log-bin-trust-routine-creators removes these errors. Binlogging of CREATE PROCEDURE|FUNCTION. sql/sql_acl.cc: No thd==0 in tables_ok(). sql/sql_parse.cc: Binlogging of CALL (and not of the substatements of the SP). If SP returns error, we don't binlog it (see comment); we push warning in this case. Binlogging of ALTER|DROP PROCEDURE|FUNCTION with safety messages.

Close mysql.proc, opened with open_proc_table_for_read().
SYNOPSIS
close_proc_table()
Fix for bug #10055 "Using stored function with information_schema causes empty result set". To enable full access to contents of I_S tables from stored functions or statements that use them, we manipulate with thread's open tables state and ensure that we won't cause deadlock when we open tables by ignoring flushes and name-locks. Building of contents of I_S.TABLES no longer requires locking of tables since we use use handler::info() method with HA_STATUS_AUTO flag instead of handler::update_auto_increment() for obtaining information about auto-increment values. But this also means that handlers have to implement support for HA_STATUS_AUTO flag (particularly InnoDB needs it). mysql-test/r/alter_table.result: Updated test results. This change was caused by the fact that now when we build contents of I_S tables (and thus output of SHOW INDEX) we don't use instances of tables which may be already opened and locked by thread (we always use new instance). mysql-test/r/information_schema.result: Added test which checks how information about current auto-increment value for table is reported in INFORMATION_SCHEMA.TABLES view. mysql-test/r/sp.result: Added test for bug #10055 "Using stored function with information_schema causes empty result set". mysql-test/t/information_schema.test: Added test which checks how information about current auto-increment value for table is reported in INFORMATION_SCHEMA.TABLES view. mysql-test/t/sp.test: Added test for bug #10055 "Using stored function with information_schema causes empty result set". sql/mysql_priv.h: close_thread_tables(): Get rid of 'stopper' argument which is no longer used. Now when we need to open and then close some table without touching tables which are already opened we use THD::reset_n/restore_backup_open_tables_state() methods. open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sp.cc: close_proc_table/open_proc_table_for_read/db_find_routine(): Replaced push_open_tables_state/pop_open_tables_state() methods which were saving/restoring current open tables state in/from THD::open_state_list with reset_n_backup_open_tables_state/restore_backup_open_tables_state() methods which assume that backup storage for this state is allocated on stack (or elsewhere) by their caller. open_proc_table_for_read(): Since now we can have several open tables states stacked up we can't rely rely on checking whether we have some tables open in previous state. Instead we always assume that some tables are open and we need to ignore flush while locking mysql.proc. We don't really need MYSQL_LOCK_IGNORE_GLOBAL_READ_LOCK in this case since we open mysql.proc table only for reading. sql/sp.h: Added declarations of open_proc_table_for_read()/close_proc_table() to be able to use them in sql_show.cc. sql/sql_base.cc: close_thread_tables(): Get rid of 'stopper' argument which is no longer used.

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.

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.

/*
Open the mysql.proc table for read.
SYNOPSIS
open_proc_table_for_read()
Fix for bug #10055 "Using stored function with information_schema causes empty result set". To enable full access to contents of I_S tables from stored functions or statements that use them, we manipulate with thread's open tables state and ensure that we won't cause deadlock when we open tables by ignoring flushes and name-locks. Building of contents of I_S.TABLES no longer requires locking of tables since we use use handler::info() method with HA_STATUS_AUTO flag instead of handler::update_auto_increment() for obtaining information about auto-increment values. But this also means that handlers have to implement support for HA_STATUS_AUTO flag (particularly InnoDB needs it). mysql-test/r/alter_table.result: Updated test results. This change was caused by the fact that now when we build contents of I_S tables (and thus output of SHOW INDEX) we don't use instances of tables which may be already opened and locked by thread (we always use new instance). mysql-test/r/information_schema.result: Added test which checks how information about current auto-increment value for table is reported in INFORMATION_SCHEMA.TABLES view. mysql-test/r/sp.result: Added test for bug #10055 "Using stored function with information_schema causes empty result set". mysql-test/t/information_schema.test: Added test which checks how information about current auto-increment value for table is reported in INFORMATION_SCHEMA.TABLES view. mysql-test/t/sp.test: Added test for bug #10055 "Using stored function with information_schema causes empty result set". sql/mysql_priv.h: close_thread_tables(): Get rid of 'stopper' argument which is no longer used. Now when we need to open and then close some table without touching tables which are already opened we use THD::reset_n/restore_backup_open_tables_state() methods. open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sp.cc: close_proc_table/open_proc_table_for_read/db_find_routine(): Replaced push_open_tables_state/pop_open_tables_state() methods which were saving/restoring current open tables state in/from THD::open_state_list with reset_n_backup_open_tables_state/restore_backup_open_tables_state() methods which assume that backup storage for this state is allocated on stack (or elsewhere) by their caller. open_proc_table_for_read(): Since now we can have several open tables states stacked up we can't rely rely on checking whether we have some tables open in previous state. Instead we always assume that some tables are open and we need to ignore flush while locking mysql.proc. We don't really need MYSQL_LOCK_IGNORE_GLOBAL_READ_LOCK in this case since we open mysql.proc table only for reading. sql/sp.h: Added declarations of open_proc_table_for_read()/close_proc_table() to be able to use them in sql_show.cc. sql/sql_base.cc: close_thread_tables(): Get rid of 'stopper' argument which is no longer used.

NOTES
Thanks to restrictions which we put on opening and locking of
this table for writing, we can open and lock it for reading
even when we already have some other tables open and locked.
One must call close_proc_table() to close table opened with
this call.

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.

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/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.

Fix for bug #10055 "Using stored function with information_schema causes empty result set". To enable full access to contents of I_S tables from stored functions or statements that use them, we manipulate with thread's open tables state and ensure that we won't cause deadlock when we open tables by ignoring flushes and name-locks. Building of contents of I_S.TABLES no longer requires locking of tables since we use use handler::info() method with HA_STATUS_AUTO flag instead of handler::update_auto_increment() for obtaining information about auto-increment values. But this also means that handlers have to implement support for HA_STATUS_AUTO flag (particularly InnoDB needs it). mysql-test/r/alter_table.result: Updated test results. This change was caused by the fact that now when we build contents of I_S tables (and thus output of SHOW INDEX) we don't use instances of tables which may be already opened and locked by thread (we always use new instance). mysql-test/r/information_schema.result: Added test which checks how information about current auto-increment value for table is reported in INFORMATION_SCHEMA.TABLES view. mysql-test/r/sp.result: Added test for bug #10055 "Using stored function with information_schema causes empty result set". mysql-test/t/information_schema.test: Added test which checks how information about current auto-increment value for table is reported in INFORMATION_SCHEMA.TABLES view. mysql-test/t/sp.test: Added test for bug #10055 "Using stored function with information_schema causes empty result set". sql/mysql_priv.h: close_thread_tables(): Get rid of 'stopper' argument which is no longer used. Now when we need to open and then close some table without touching tables which are already opened we use THD::reset_n/restore_backup_open_tables_state() methods. open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sp.cc: close_proc_table/open_proc_table_for_read/db_find_routine(): Replaced push_open_tables_state/pop_open_tables_state() methods which were saving/restoring current open tables state in/from THD::open_state_list with reset_n_backup_open_tables_state/restore_backup_open_tables_state() methods which assume that backup storage for this state is allocated on stack (or elsewhere) by their caller. open_proc_table_for_read(): Since now we can have several open tables states stacked up we can't rely rely on checking whether we have some tables open in previous state. Instead we always assume that some tables are open and we need to ignore flush while locking mysql.proc. We don't really need MYSQL_LOCK_IGNORE_GLOBAL_READ_LOCK in this case since we open mysql.proc table only for reading. sql/sp.h: Added declarations of open_proc_table_for_read()/close_proc_table() to be able to use them in sql_show.cc. sql/sql_base.cc: close_thread_tables(): Get rid of 'stopper' argument which is no longer used. Now when we need to open and then close some table without touching tables which are already opened we use THD::reset_n/restore_backup_open_tables_state() methods. open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sql_class.cc: Open_tables_state, THD: Replaced push_open_tables_state/pop_open_tables_state() methods which were saving/restoring current open tables state in/from THD::open_state_list with reset_n_backup_open_tables_state/restore_backup_open_tables_state() methods which assume that backup storage for this state is allocated on stack (or elsewhere) by their caller. sql/sql_class.h: Open_tables_state, THD: Replaced push_open_tables_state/pop_open_tables_state() methods which were saving/restoring current open tables state in/from THD::open_state_list with reset_n_backup_open_tables_state/restore_backup_open_tables_state() methods which assume that backup storage for this state is allocated on stack (or elsewhere) by their caller. sql/sql_handler.cc: open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sql_prepare.cc: open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sql_show.cc: get_all_tables(): Now we use THD::reset_n_/restore_backup_open_tables_state() for saving/restoring open tables state instead of working with it directly (This also allows us to have proper content of I_S system tables in statements with stored functions and in stored functions). We also ignore possible flushes when opening tables (we may create deadlock otherwise). Also we do all needed manipulations with LEX in this function and not in get_schema_tables_result() now. get_schema_tables_record(): Let us use handler::info() method with HA_STATUS_AUTO flag for obtaining information about table's auto-increment value. This allows to avoid locking of tables which is needed when we use handler::update_auto_increment() method. fill_schema_proc(): Now we use open_proc_table_for_read/close_proc_table() for access to mysql.proc table (so we won't cause deadlock if we already have some tables open and locked, this also allows us to have proper content in ROUTINES system table in statements using stored functions/in stored functions). get_schema_tables_result(): Moved all manipulations with Open_tables_state and LEX needed for safe opening of tables to ST_SCHEMA_TABLE::fill_table functions (i.e. get_all_tables() and fill_schema_proc()). sql/sql_update.cc: open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them.

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.

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.

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.

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.

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.

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.

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.

In order to make ALTER PROCEDURE|FUNCTION work correctly, and in general to make characteristics (and SHOW) work right, we had to separate the old definition blob in the mysql.proc table into separate fields for parameters, return type, and body, and handle the characteristics (like SQL SECURITY) separately... and then reassemble the CREATE string for parsing, of course. This is rather ugly, mostly the parser bit. (Hopefully that will be better with the new parser.)

Fix for bug #10055 "Using stored function with information_schema causes empty result set". To enable full access to contents of I_S tables from stored functions or statements that use them, we manipulate with thread's open tables state and ensure that we won't cause deadlock when we open tables by ignoring flushes and name-locks. Building of contents of I_S.TABLES no longer requires locking of tables since we use use handler::info() method with HA_STATUS_AUTO flag instead of handler::update_auto_increment() for obtaining information about auto-increment values. But this also means that handlers have to implement support for HA_STATUS_AUTO flag (particularly InnoDB needs it). mysql-test/r/alter_table.result: Updated test results. This change was caused by the fact that now when we build contents of I_S tables (and thus output of SHOW INDEX) we don't use instances of tables which may be already opened and locked by thread (we always use new instance). mysql-test/r/information_schema.result: Added test which checks how information about current auto-increment value for table is reported in INFORMATION_SCHEMA.TABLES view. mysql-test/r/sp.result: Added test for bug #10055 "Using stored function with information_schema causes empty result set". mysql-test/t/information_schema.test: Added test which checks how information about current auto-increment value for table is reported in INFORMATION_SCHEMA.TABLES view. mysql-test/t/sp.test: Added test for bug #10055 "Using stored function with information_schema causes empty result set". sql/mysql_priv.h: close_thread_tables(): Get rid of 'stopper' argument which is no longer used. Now when we need to open and then close some table without touching tables which are already opened we use THD::reset_n/restore_backup_open_tables_state() methods. open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sp.cc: close_proc_table/open_proc_table_for_read/db_find_routine(): Replaced push_open_tables_state/pop_open_tables_state() methods which were saving/restoring current open tables state in/from THD::open_state_list with reset_n_backup_open_tables_state/restore_backup_open_tables_state() methods which assume that backup storage for this state is allocated on stack (or elsewhere) by their caller. open_proc_table_for_read(): Since now we can have several open tables states stacked up we can't rely rely on checking whether we have some tables open in previous state. Instead we always assume that some tables are open and we need to ignore flush while locking mysql.proc. We don't really need MYSQL_LOCK_IGNORE_GLOBAL_READ_LOCK in this case since we open mysql.proc table only for reading. sql/sp.h: Added declarations of open_proc_table_for_read()/close_proc_table() to be able to use them in sql_show.cc. sql/sql_base.cc: close_thread_tables(): Get rid of 'stopper' argument which is no longer used. Now when we need to open and then close some table without touching tables which are already opened we use THD::reset_n/restore_backup_open_tables_state() methods. open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sql_class.cc: Open_tables_state, THD: Replaced push_open_tables_state/pop_open_tables_state() methods which were saving/restoring current open tables state in/from THD::open_state_list with reset_n_backup_open_tables_state/restore_backup_open_tables_state() methods which assume that backup storage for this state is allocated on stack (or elsewhere) by their caller. sql/sql_class.h: Open_tables_state, THD: Replaced push_open_tables_state/pop_open_tables_state() methods which were saving/restoring current open tables state in/from THD::open_state_list with reset_n_backup_open_tables_state/restore_backup_open_tables_state() methods which assume that backup storage for this state is allocated on stack (or elsewhere) by their caller. sql/sql_handler.cc: open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sql_prepare.cc: open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sql_show.cc: get_all_tables(): Now we use THD::reset_n_/restore_backup_open_tables_state() for saving/restoring open tables state instead of working with it directly (This also allows us to have proper content of I_S system tables in statements with stored functions and in stored functions). We also ignore possible flushes when opening tables (we may create deadlock otherwise). Also we do all needed manipulations with LEX in this function and not in get_schema_tables_result() now. get_schema_tables_record(): Let us use handler::info() method with HA_STATUS_AUTO flag for obtaining information about table's auto-increment value. This allows to avoid locking of tables which is needed when we use handler::update_auto_increment() method. fill_schema_proc(): Now we use open_proc_table_for_read/close_proc_table() for access to mysql.proc table (so we won't cause deadlock if we already have some tables open and locked, this also allows us to have proper content in ROUTINES system table in statements using stored functions/in stored functions). get_schema_tables_result(): Moved all manipulations with Open_tables_state and LEX needed for safe opening of tables to ST_SCHEMA_TABLE::fill_table functions (i.e. get_all_tables() and fill_schema_proc()). sql/sql_update.cc: open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them.

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.

Fix for bug #10055 "Using stored function with information_schema causes empty result set". To enable full access to contents of I_S tables from stored functions or statements that use them, we manipulate with thread's open tables state and ensure that we won't cause deadlock when we open tables by ignoring flushes and name-locks. Building of contents of I_S.TABLES no longer requires locking of tables since we use use handler::info() method with HA_STATUS_AUTO flag instead of handler::update_auto_increment() for obtaining information about auto-increment values. But this also means that handlers have to implement support for HA_STATUS_AUTO flag (particularly InnoDB needs it). mysql-test/r/alter_table.result: Updated test results. This change was caused by the fact that now when we build contents of I_S tables (and thus output of SHOW INDEX) we don't use instances of tables which may be already opened and locked by thread (we always use new instance). mysql-test/r/information_schema.result: Added test which checks how information about current auto-increment value for table is reported in INFORMATION_SCHEMA.TABLES view. mysql-test/r/sp.result: Added test for bug #10055 "Using stored function with information_schema causes empty result set". mysql-test/t/information_schema.test: Added test which checks how information about current auto-increment value for table is reported in INFORMATION_SCHEMA.TABLES view. mysql-test/t/sp.test: Added test for bug #10055 "Using stored function with information_schema causes empty result set". sql/mysql_priv.h: close_thread_tables(): Get rid of 'stopper' argument which is no longer used. Now when we need to open and then close some table without touching tables which are already opened we use THD::reset_n/restore_backup_open_tables_state() methods. open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sp.cc: close_proc_table/open_proc_table_for_read/db_find_routine(): Replaced push_open_tables_state/pop_open_tables_state() methods which were saving/restoring current open tables state in/from THD::open_state_list with reset_n_backup_open_tables_state/restore_backup_open_tables_state() methods which assume that backup storage for this state is allocated on stack (or elsewhere) by their caller. open_proc_table_for_read(): Since now we can have several open tables states stacked up we can't rely rely on checking whether we have some tables open in previous state. Instead we always assume that some tables are open and we need to ignore flush while locking mysql.proc. We don't really need MYSQL_LOCK_IGNORE_GLOBAL_READ_LOCK in this case since we open mysql.proc table only for reading. sql/sp.h: Added declarations of open_proc_table_for_read()/close_proc_table() to be able to use them in sql_show.cc. sql/sql_base.cc: close_thread_tables(): Get rid of 'stopper' argument which is no longer used. Now when we need to open and then close some table without touching tables which are already opened we use THD::reset_n/restore_backup_open_tables_state() methods. open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sql_class.cc: Open_tables_state, THD: Replaced push_open_tables_state/pop_open_tables_state() methods which were saving/restoring current open tables state in/from THD::open_state_list with reset_n_backup_open_tables_state/restore_backup_open_tables_state() methods which assume that backup storage for this state is allocated on stack (or elsewhere) by their caller. sql/sql_class.h: Open_tables_state, THD: Replaced push_open_tables_state/pop_open_tables_state() methods which were saving/restoring current open tables state in/from THD::open_state_list with reset_n_backup_open_tables_state/restore_backup_open_tables_state() methods which assume that backup storage for this state is allocated on stack (or elsewhere) by their caller. sql/sql_handler.cc: open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sql_prepare.cc: open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sql_show.cc: get_all_tables(): Now we use THD::reset_n_/restore_backup_open_tables_state() for saving/restoring open tables state instead of working with it directly (This also allows us to have proper content of I_S system tables in statements with stored functions and in stored functions). We also ignore possible flushes when opening tables (we may create deadlock otherwise). Also we do all needed manipulations with LEX in this function and not in get_schema_tables_result() now. get_schema_tables_record(): Let us use handler::info() method with HA_STATUS_AUTO flag for obtaining information about table's auto-increment value. This allows to avoid locking of tables which is needed when we use handler::update_auto_increment() method. fill_schema_proc(): Now we use open_proc_table_for_read/close_proc_table() for access to mysql.proc table (so we won't cause deadlock if we already have some tables open and locked, this also allows us to have proper content in ROUTINES system table in statements using stored functions/in stored functions). get_schema_tables_result(): Moved all manipulations with Open_tables_state and LEX needed for safe opening of tables to ST_SCHEMA_TABLE::fill_table functions (i.e. get_all_tables() and fill_schema_proc()). sql/sql_update.cc: open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them.

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.

Approximative fixes for BUG#2610,2611,9100 i.e. WL#2146 binlogging/replication of routines (stored procs and functions). Approximative, because it's using our binlogging way (what we call "query"-level) and this is not as good as record-level binlog (5.1) would be. It imposes several limitations to routines, and has caveats (which I'll document, and for which the server will try to issue errors but that is not always possible). Reason I don't propagate caller info to the binlog as planned is that on master and slave users may be different; even with that some caveats would remain. mysql-test/mysql-test-run.sh: In the testsuite we know what we do, we are not creating nasty routines, and breaking binlog is ok except in rpl_sp. mysql-test/r/blackhole.result: Updating results now that 4.1 has been merged mysql-test/valgrind.supp: Some suppressions for Valgrind (useful on my machine Suse 9.1); this is just adding to the already existing suppressions of pthread and dl. sql/item_func.cc: Don't binlog the substatements when executing a function. If the function is declared to modify data and does not complete, warning "broken binlog". Note that SELECT myfunc() will not be binlogged even if myfunc() updates data (will be documented); but INSERT INTO t VALUES(myfunc()) will be binlogged (what decides is if the caller gets binlogged; the function changes nothing to binlogging). sql/log_event.cc: Just making functions which can be re-used when we binlog more strings in status_vars in Query_log_event (e.g. one day "user", "host"). sql/log_event.h: comment sql/mysql_priv.h: --log-bin-trust-routine-creators sql/mysqld.cc: --log-bin-trust-routine-creators sql/set_var.cc: --log-bin-trust-routine-creators sql/share/errmsg.txt: error messages to warn about problems with routines and binlog sql/slave.cc: If in a routine, replication table inclusion/exclusion rules always answer "replicate!" (see comment in code). sql/sp.cc: If binlog is on: errors if one wants to create a non-deterministic update routine (repeatability problem - note that the test is not perfect for functions) or does not have SUPER (because routines can easily be made to destroy slave's data with just CREATE ROUTINE and EXECUTE priv on master). --log-bin-trust-routine-creators removes these errors. Binlogging of CREATE PROCEDURE|FUNCTION. sql/sql_acl.cc: No thd==0 in tables_ok(). sql/sql_parse.cc: Binlogging of CALL (and not of the substatements of the SP). If SP returns error, we don't binlog it (see comment); we push warning in this case. Binlogging of ALTER|DROP PROCEDURE|FUNCTION with safety messages.

In order to make ALTER PROCEDURE|FUNCTION work correctly, and in general to make characteristics (and SHOW) work right, we had to separate the old definition blob in the mysql.proc table into separate fields for parameters, return type, and body, and handle the characteristics (like SQL SECURITY) separately... and then reassemble the CREATE string for parsing, of course. This is rather ugly, mostly the parser bit. (Hopefully that will be better with the new parser.) Docs/sp-imp-spec.txt: Separated the definitions string of the procedure into different columns in the mysql.proc schema. mysql-test/r/sp.result: New characteristics tests. mysql-test/t/sp.test: New characteristics tests. scripts/mysql_create_system_tables.sh: Separated the definitions string of the procedure into different columns in the mysql.proc schema. scripts/mysql_fix_privilege_tables.sql: Separated the definitions string of the procedure into different columns in the mysql.proc schema. sql/sp.cc: Separated the definitions string of the procedure into different columns. Rewrote much of the code related this (have a assemble the definition string from its different parts now) and the way characteristics are now handled, in order to make ALTER actually work. sql/sp.h: Changed prototypes. sql/sp_head.cc: Rewrote much of the code related to the new mysql.proc schema with separate definition fields (have to assemble the definition string from its different parts now) and the way characteristics are now handled, in order to make ALTER actually work. sql/sp_head.h: Separated the different parts of the definition strings: name, parameters, return type (for functions) and body. sql/sql_yacc.yy: Separated the different parts of the definition strings: name, parameters, return type (for functions) and body. This is ugly and messy; hopefully there's a more elegant way to do this when the new parser is installed.

Fix for bug #10055 "Using stored function with information_schema causes empty result set". To enable full access to contents of I_S tables from stored functions or statements that use them, we manipulate with thread's open tables state and ensure that we won't cause deadlock when we open tables by ignoring flushes and name-locks. Building of contents of I_S.TABLES no longer requires locking of tables since we use use handler::info() method with HA_STATUS_AUTO flag instead of handler::update_auto_increment() for obtaining information about auto-increment values. But this also means that handlers have to implement support for HA_STATUS_AUTO flag (particularly InnoDB needs it). mysql-test/r/alter_table.result: Updated test results. This change was caused by the fact that now when we build contents of I_S tables (and thus output of SHOW INDEX) we don't use instances of tables which may be already opened and locked by thread (we always use new instance). mysql-test/r/information_schema.result: Added test which checks how information about current auto-increment value for table is reported in INFORMATION_SCHEMA.TABLES view. mysql-test/r/sp.result: Added test for bug #10055 "Using stored function with information_schema causes empty result set". mysql-test/t/information_schema.test: Added test which checks how information about current auto-increment value for table is reported in INFORMATION_SCHEMA.TABLES view. mysql-test/t/sp.test: Added test for bug #10055 "Using stored function with information_schema causes empty result set". sql/mysql_priv.h: close_thread_tables(): Get rid of 'stopper' argument which is no longer used. Now when we need to open and then close some table without touching tables which are already opened we use THD::reset_n/restore_backup_open_tables_state() methods. open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sp.cc: close_proc_table/open_proc_table_for_read/db_find_routine(): Replaced push_open_tables_state/pop_open_tables_state() methods which were saving/restoring current open tables state in/from THD::open_state_list with reset_n_backup_open_tables_state/restore_backup_open_tables_state() methods which assume that backup storage for this state is allocated on stack (or elsewhere) by their caller. open_proc_table_for_read(): Since now we can have several open tables states stacked up we can't rely rely on checking whether we have some tables open in previous state. Instead we always assume that some tables are open and we need to ignore flush while locking mysql.proc. We don't really need MYSQL_LOCK_IGNORE_GLOBAL_READ_LOCK in this case since we open mysql.proc table only for reading. sql/sp.h: Added declarations of open_proc_table_for_read()/close_proc_table() to be able to use them in sql_show.cc. sql/sql_base.cc: close_thread_tables(): Get rid of 'stopper' argument which is no longer used. Now when we need to open and then close some table without touching tables which are already opened we use THD::reset_n/restore_backup_open_tables_state() methods. open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sql_class.cc: Open_tables_state, THD: Replaced push_open_tables_state/pop_open_tables_state() methods which were saving/restoring current open tables state in/from THD::open_state_list with reset_n_backup_open_tables_state/restore_backup_open_tables_state() methods which assume that backup storage for this state is allocated on stack (or elsewhere) by their caller. sql/sql_class.h: Open_tables_state, THD: Replaced push_open_tables_state/pop_open_tables_state() methods which were saving/restoring current open tables state in/from THD::open_state_list with reset_n_backup_open_tables_state/restore_backup_open_tables_state() methods which assume that backup storage for this state is allocated on stack (or elsewhere) by their caller. sql/sql_handler.cc: open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sql_prepare.cc: open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them. sql/sql_show.cc: get_all_tables(): Now we use THD::reset_n_/restore_backup_open_tables_state() for saving/restoring open tables state instead of working with it directly (This also allows us to have proper content of I_S system tables in statements with stored functions and in stored functions). We also ignore possible flushes when opening tables (we may create deadlock otherwise). Also we do all needed manipulations with LEX in this function and not in get_schema_tables_result() now. get_schema_tables_record(): Let us use handler::info() method with HA_STATUS_AUTO flag for obtaining information about table's auto-increment value. This allows to avoid locking of tables which is needed when we use handler::update_auto_increment() method. fill_schema_proc(): Now we use open_proc_table_for_read/close_proc_table() for access to mysql.proc table (so we won't cause deadlock if we already have some tables open and locked, this also allows us to have proper content in ROUTINES system table in statements using stored functions/in stored functions). get_schema_tables_result(): Moved all manipulations with Open_tables_state and LEX needed for safe opening of tables to ST_SCHEMA_TABLE::fill_table functions (i.e. get_all_tables() and fill_schema_proc()). sql/sql_update.cc: open_tables()/open_normal_and_derived_tables(): Added 'flags' argument to be able open tables even if some has done a flush or hold namelock on them.

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/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).

Most of the groundwork for sprint task 729 (implement FUNCTIONs). Expanded the mysql.proc table, reworked the find/create/drop functions completely, added new functions for FUNCTIONs (lotta functions here :), got rid of some unnecessary use of Item_strings while at it.

A fix and a test case for Bug#19022 "Memory bug when switching db during trigger execution" Bug#17199 "Problem when view calls function from another database." Bug#18444 "Fully qualified stored function names don't work correctly in SELECT statements" Documentation note: this patch introduces a change in behaviour of prepared statements. This patch adds a few new invariants with regard to how THD::db should be used. These invariants should be preserved in future: - one should never refer to THD::db by pointer and always make a deep copy (strmake, strdup) - one should never compare two databases by pointer, but use strncmp or my_strncasecmp - TABLE_LIST object table->db should be always initialized in the parser or by creator of the object. For prepared statements it means that if the current database is changed after a statement is prepared, the database that was current at prepare remains active. This also means that you can not prepare a statement that implicitly refers to the current database if the latter is not set. This is not documented, and therefore needs documentation. This is NOT a change in behavior for almost all SQL statements except: - ALTER TABLE t1 RENAME t2 - OPTIMIZE TABLE t1 - ANALYZE TABLE t1 - TRUNCATE TABLE t1 -- until this patch t1 or t2 could be evaluated at the first execution of prepared statement. CURRENT_DATABASE() still works OK and is evaluated at every execution of prepared statement. Note, that in stored routines this is not an issue as the default database is the database of the stored procedure and "use" statement is prohibited in stored routines. This patch makes obsolete the use of check_db_used (it was never used in the old code too) and all other places that check for table->db and assign it from THD::db if it's NULL, except the parser. How this patch was created: THD::{db,db_length} were replaced with a LEX_STRING, THD::db. All the places that refer to THD::{db,db_length} were manually checked and: - if the place uses thd->db by pointer, it was fixed to make a deep copy - if a place compared two db pointers, it was fixed to compare them by value (via strcmp/my_strcasecmp, whatever was approproate) Then this intermediate patch was used to write a smaller patch that does the same thing but without a rename. TODO in 5.1: - remove check_db_used - deploy THD::set_db in mysql_change_db See also comments to individual files. mysql-test/r/create.result: Modify the result file: a database can never be NULL. mysql-test/r/ps.result: Update test results (Bug#17199 et al) mysql-test/r/sp.result: Update test results (Bug#17199 et al) mysql-test/t/create.test: Update the id of the returned error. mysql-test/t/ps.test: Add test coverage for prepared statements and current database. In scope of work on Bug#17199 "Problem when view calls function from another database." mysql-test/t/sp.test: Add a test case for Bug#17199 "Problem when view calls function from another database." and Bug#18444 "Fully qualified stored function names don't work correctly in SELECT statements". Test a complementary problem. sql/item_strfunc.cc: Touch the code that reads thd->db (cleanup). sql/log_event.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/slave.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/slave.h: Remove a declaration for a method that is used only in one module. sql/sp.cc: Rewrite sp_use_new_db: this is a cleanup that I needed in order to understand this function and ensure that it has no bugs. sql/sp.h: Add a new declaration for sp_use_new_db (uses LEX_STRINGs) and a comment. sql/sp_head.cc: - drop sp_name_current_db_new - a creator of sp_name class that was used when sp_name was created for an identifier without an explicitly initialized database. Now we pass thd->db to constructor of sp_name right in the parser. - rewrite sp_head::init_strings: name->m_db is always set now - use the new variant of sp_use_new_db - we don't need to update thd->db with SP MEM_ROOT pointer anymore when parsing a stored procedure, as noone will refer to it (yes!) sql/sp_head.h: - remove unneded methods and members sql/sql_class.h: - introduce 3 THD methods to work with THD::db: .set_db to assign the current database .reset_db to reset the current database (temporarily) or set it to NULL .opt_copy_db_to - to deep-copy thd->db to a pointer if it's not NULL sql/sql_db.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/sql_insert.cc: - replace checks with asserts: table_list->db must be always set in the parser. sql/sql_lex.h: - add a comment sql/sql_parse.cc: - implement the invariant described in the changeset comment. - remove juggling with lex->sphead in SQLCOM_CREATE_PROCEDURE: now db_load_routine uses its own LEX object and doesn't damage the main LEX. - add DBUG_ASSERT(0) to unused "check_db_used" sql/sql_table.cc: - replace a check with an assert (table_ident->db) sql/sql_trigger.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/sql_udf.cc: - use thd->set_db instead of direct modification of to thd->db sql/sql_view.cc: - replace a check with an assert (view->db) sql/sql_yacc.yy: - make sure that we always copy table->db or name->db or ident->db or select_lex->db from thd->db if the former is not set. If thd->db is not set but is accessed, return an error. sql/tztime.cc: - be nice, never copy thd->db by pointer.

Implementation of WL#2897: Complete definer support in the stored routines. The idea is to add DEFINER-clause in CREATE PROCEDURE and CREATE FUNCTION statements. Almost all support of definer in stored routines had been already done before this patch. NOTE: this patch changes behaviour of dumping stored routines in mysqldump. Before this patch, mysqldump did not dump DEFINER-clause for stored routines and this was documented behaviour. In order to get full information about stored routines, one should have dumped mysql.proc table. This patch changes this behaviour, so that DEFINER-clause is dumped. Since DEFINER-clause is not supported in CREATE PROCEDURE | FUNCTION statements before this patch, the clause is covered by additional version-specific comments. client/mysqldump.c: Updated the code for dumping stored routines: cover DEFINER-clause into version-specific comment. mysql-test/r/gis.result: Updated result file after adding DEFINER-clause. mysql-test/r/information_schema.result: Updated result file after adding DEFINER-clause. mysql-test/r/mysqldump.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_ddl.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_sp.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_trigger.result: Updated result file after adding DEFINER-clause. mysql-test/r/sp-security.result: Updated result file after adding DEFINER-clause. mysql-test/r/sp.result: Updated result file after adding DEFINER-clause. mysql-test/r/sql_mode.result: Updated result file after adding DEFINER-clause. mysql-test/t/sp-security.test: Updated result file after adding DEFINER-clause. sql/sp.cc: Added DEFINER-clause. sql/sp_head.cc: Added a new convenient variant of set_definer() operation. sql/sp_head.h: Updated result file after adding DEFINER-clause. sql/sql_lex.h: Renamed trigger_definition_begin into stmt_definition_begin to be used for triggers and stored routines. sql/sql_parse.cc: Check DEFINER-clause. sql/sql_trigger.cc: Renamed trigger_definition_begin into stmt_definition_begin to be used for triggers and stored routines. sql/sql_yacc.yy: Added DEFINER-clause.

A fix and a test case for Bug#19022 "Memory bug when switching db during trigger execution" Bug#17199 "Problem when view calls function from another database." Bug#18444 "Fully qualified stored function names don't work correctly in SELECT statements" Documentation note: this patch introduces a change in behaviour of prepared statements. This patch adds a few new invariants with regard to how THD::db should be used. These invariants should be preserved in future: - one should never refer to THD::db by pointer and always make a deep copy (strmake, strdup) - one should never compare two databases by pointer, but use strncmp or my_strncasecmp - TABLE_LIST object table->db should be always initialized in the parser or by creator of the object. For prepared statements it means that if the current database is changed after a statement is prepared, the database that was current at prepare remains active. This also means that you can not prepare a statement that implicitly refers to the current database if the latter is not set. This is not documented, and therefore needs documentation. This is NOT a change in behavior for almost all SQL statements except: - ALTER TABLE t1 RENAME t2 - OPTIMIZE TABLE t1 - ANALYZE TABLE t1 - TRUNCATE TABLE t1 -- until this patch t1 or t2 could be evaluated at the first execution of prepared statement. CURRENT_DATABASE() still works OK and is evaluated at every execution of prepared statement. Note, that in stored routines this is not an issue as the default database is the database of the stored procedure and "use" statement is prohibited in stored routines. This patch makes obsolete the use of check_db_used (it was never used in the old code too) and all other places that check for table->db and assign it from THD::db if it's NULL, except the parser. How this patch was created: THD::{db,db_length} were replaced with a LEX_STRING, THD::db. All the places that refer to THD::{db,db_length} were manually checked and: - if the place uses thd->db by pointer, it was fixed to make a deep copy - if a place compared two db pointers, it was fixed to compare them by value (via strcmp/my_strcasecmp, whatever was approproate) Then this intermediate patch was used to write a smaller patch that does the same thing but without a rename. TODO in 5.1: - remove check_db_used - deploy THD::set_db in mysql_change_db See also comments to individual files. mysql-test/r/create.result: Modify the result file: a database can never be NULL. mysql-test/r/ps.result: Update test results (Bug#17199 et al) mysql-test/r/sp.result: Update test results (Bug#17199 et al) mysql-test/t/create.test: Update the id of the returned error. mysql-test/t/ps.test: Add test coverage for prepared statements and current database. In scope of work on Bug#17199 "Problem when view calls function from another database." mysql-test/t/sp.test: Add a test case for Bug#17199 "Problem when view calls function from another database." and Bug#18444 "Fully qualified stored function names don't work correctly in SELECT statements". Test a complementary problem. sql/item_strfunc.cc: Touch the code that reads thd->db (cleanup). sql/log_event.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/slave.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/slave.h: Remove a declaration for a method that is used only in one module. sql/sp.cc: Rewrite sp_use_new_db: this is a cleanup that I needed in order to understand this function and ensure that it has no bugs. sql/sp.h: Add a new declaration for sp_use_new_db (uses LEX_STRINGs) and a comment. sql/sp_head.cc: - drop sp_name_current_db_new - a creator of sp_name class that was used when sp_name was created for an identifier without an explicitly initialized database. Now we pass thd->db to constructor of sp_name right in the parser. - rewrite sp_head::init_strings: name->m_db is always set now - use the new variant of sp_use_new_db - we don't need to update thd->db with SP MEM_ROOT pointer anymore when parsing a stored procedure, as noone will refer to it (yes!) sql/sp_head.h: - remove unneded methods and members sql/sql_class.h: - introduce 3 THD methods to work with THD::db: .set_db to assign the current database .reset_db to reset the current database (temporarily) or set it to NULL .opt_copy_db_to - to deep-copy thd->db to a pointer if it's not NULL sql/sql_db.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/sql_insert.cc: - replace checks with asserts: table_list->db must be always set in the parser. sql/sql_lex.h: - add a comment sql/sql_parse.cc: - implement the invariant described in the changeset comment. - remove juggling with lex->sphead in SQLCOM_CREATE_PROCEDURE: now db_load_routine uses its own LEX object and doesn't damage the main LEX. - add DBUG_ASSERT(0) to unused "check_db_used" sql/sql_table.cc: - replace a check with an assert (table_ident->db) sql/sql_trigger.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/sql_udf.cc: - use thd->set_db instead of direct modification of to thd->db sql/sql_view.cc: - replace a check with an assert (view->db) sql/sql_yacc.yy: - make sure that we always copy table->db or name->db or ident->db or select_lex->db from thd->db if the former is not set. If thd->db is not set but is accessed, return an error. sql/tztime.cc: - be nice, never copy thd->db by pointer.

Implementation of WL#2897: Complete definer support in the stored routines. The idea is to add DEFINER-clause in CREATE PROCEDURE and CREATE FUNCTION statements. Almost all support of definer in stored routines had been already done before this patch. NOTE: this patch changes behaviour of dumping stored routines in mysqldump. Before this patch, mysqldump did not dump DEFINER-clause for stored routines and this was documented behaviour. In order to get full information about stored routines, one should have dumped mysql.proc table. This patch changes this behaviour, so that DEFINER-clause is dumped. Since DEFINER-clause is not supported in CREATE PROCEDURE | FUNCTION statements before this patch, the clause is covered by additional version-specific comments. client/mysqldump.c: Updated the code for dumping stored routines: cover DEFINER-clause into version-specific comment. mysql-test/r/gis.result: Updated result file after adding DEFINER-clause. mysql-test/r/information_schema.result: Updated result file after adding DEFINER-clause. mysql-test/r/mysqldump.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_ddl.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_sp.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_trigger.result: Updated result file after adding DEFINER-clause. mysql-test/r/sp-security.result: Updated result file after adding DEFINER-clause. mysql-test/r/sp.result: Updated result file after adding DEFINER-clause. mysql-test/r/sql_mode.result: Updated result file after adding DEFINER-clause. mysql-test/t/sp-security.test: Updated result file after adding DEFINER-clause. sql/sp.cc: Added DEFINER-clause. sql/sp_head.cc: Added a new convenient variant of set_definer() operation. sql/sp_head.h: Updated result file after adding DEFINER-clause. sql/sql_lex.h: Renamed trigger_definition_begin into stmt_definition_begin to be used for triggers and stored routines. sql/sql_parse.cc: Check DEFINER-clause. sql/sql_trigger.cc: Renamed trigger_definition_begin into stmt_definition_begin to be used for triggers and stored routines. sql/sql_yacc.yy: Added DEFINER-clause.

Patch for WL#2894: Make stored routine variables work 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;

Fix for BUG#16211: Stored function return type for strings is ignored. Fix for BUG#16676: Database CHARSET not used for stored procedures The problem in BUG#16211 is that CHARSET-clause of the return type for stored functions is just ignored. The problem in BUG#16676 is that if character set is not explicitly specified for sp-variable, the server character set is used instead of the database one. The fix has two parts: - always store CHARSET-clause of the return type along with the type definition in mysql.proc.returns column. "Always" means that CHARSET-clause is appended even if it has not been explicitly specified in CREATE FUNCTION statement (this affects BUG#16211 only). Storing CHARSET-clause if it is not specified is essential to avoid changing character set if the database character set is altered in the future. NOTE: this change is not backward compatible with the previous releases. - use database default character set if CHARSET-clause is not explicitly specified (this affects both BUG#16211 and BUG#16676). NOTE: this also breaks backward compatibility. mysql-test/r/mysqldump.result: Updated result file. mysql-test/r/sp.result: Updated result file. mysql-test/t/sp.test: Provided test cases for BUG#16211, BUG#16676. sql/mysql_priv.h: Added two convenient functions for work with databases. sql/sp.cc: 1.

Most of the groundwork for sprint task 729 (implement FUNCTIONs). Expanded the mysql.proc table, reworked the find/create/drop functions completely, added new functions for FUNCTIONs (lotta functions here :), got rid of some unnecessary use of Item_strings while at it. Extended the parser correspondingly, and fiddled around a bit to make SP FUNCTIONs coexist with UDFs. Can now CREATE and DROP FUNCTIONs. Invoking yet to come... Docs/sp-implemented.txt: Updated with info about CASCADE/RESTICT and METHOD, and some answers to questions. include/mysqld_error.h: New error message for misuse of RETURN. mysql-test/install_test_db.sh: Added enum field to mysql.proc to distinguish between FUNCTION and PROCEDURE. mysql-test/r/sp.result: New test for creating and dropping FUNCTIONS. mysql-test/t/sp.test: New test for creating and dropping FUNCTIONS. scripts/mysql_install_db.sh: Added enum field to mysql.proc to distinguish between FUNCTION and PROCEDURE. sql/lex.h: De-UDFed some symbol names, as they are now used for SPs as well. Added RETURN_SYM. sql/share/czech/errmsg.txt: New error message for misuse of RETURN. sql/share/danish/errmsg.txt: New error message for misuse of RETURN. sql/share/dutch/errmsg.txt: New error message for misuse of RETURN. sql/share/english/errmsg.txt: New error message for misuse of RETURN. sql/share/estonian/errmsg.txt: New error message for misuse of RETURN. sql/share/french/errmsg.txt: New error message for misuse of RETURN. sql/share/german/errmsg.txt: New error message for misuse of RETURN. sql/share/greek/errmsg.txt: New error message for misuse of RETURN. sql/share/hungarian/errmsg.txt: New error message for misuse of RETURN. sql/share/italian/errmsg.txt: New error message for misuse of RETURN. sql/share/japanese/errmsg.txt: New error message for misuse of RETURN. sql/share/korean/errmsg.txt: New error message for misuse of RETURN. sql/share/norwegian-ny/errmsg.txt: New error message for misuse of RETURN. sql/share/norwegian/errmsg.txt: New error message for misuse of RETURN. sql/share/polish/errmsg.txt: New error message for misuse of RETURN. sql/share/portuguese/errmsg.txt: New error message for misuse of RETURN. sql/share/romanian/errmsg.txt: New error message for misuse of RETURN. sql/share/russian/errmsg.txt: New error message for misuse of RETURN. sql/share/serbian/errmsg.txt: New error message for misuse of RETURN. sql/share/slovak/errmsg.txt: New error message for misuse of RETURN. sql/share/spanish/errmsg.txt: New error message for misuse of RETURN. sql/share/swedish/errmsg.txt: New error message for misuse of RETURN. sql/share/ukrainian/errmsg.txt: New error message for misuse of RETURN. sql/sp.cc: Major rehack to accomodate FUNCTIONs, and to make it easier to add future in-memory cache of prepared SPs. sql/sp.h: Major rehack to accomodate FUNCTIONs, and to make it easier to add future in-memory cache of prepared SPs. sql/sp_head.cc: Now creates FUNCTIONs too. (And got rid of some unnecessary Item_string use.) sql/sp_head.h: Now creates FUNCTIONs too. (And got rid of some unnecessary Item_string use.) sql/sql_lex.h: New stored FUNCTION commands. sql/sql_parse.cc: Added FUNCTION support ("drop" merged with the old UDF code), and made some additional changes for better error handling (following the sp.cc rehacking). sql/sql_yacc.yy: Some former UDF specific symbols renamed. Added CREATE FUNCTION parsing. DROP FUNCTION had to be partly merged with the old UDF code, because of the similar syntax. RETURN statement added, but still a no-op.

In order to make ALTER PROCEDURE|FUNCTION work correctly, and in general to make characteristics (and SHOW) work right, we had to separate the old definition blob in the mysql.proc table into separate fields for parameters, return type, and body, and handle the characteristics (like SQL SECURITY) separately... and then reassemble the CREATE string for parsing, of course. This is rather ugly, mostly the parser bit. (Hopefully that will be better with the new parser.) Docs/sp-imp-spec.txt: Separated the definitions string of the procedure into different columns in the mysql.proc schema. mysql-test/r/sp.result: New characteristics tests. mysql-test/t/sp.test: New characteristics tests. scripts/mysql_create_system_tables.sh: Separated the definitions string of the procedure into different columns in the mysql.proc schema. scripts/mysql_fix_privilege_tables.sql: Separated the definitions string of the procedure into different columns in the mysql.proc schema. sql/sp.cc: Separated the definitions string of the procedure into different columns. Rewrote much of the code related this (have a assemble the definition string from its different parts now) and the way characteristics are now handled, in order to make ALTER actually work. sql/sp.h: Changed prototypes. sql/sp_head.cc: Rewrote much of the code related to the new mysql.proc schema with separate definition fields (have to assemble the definition string from its different parts now) and the way characteristics are now handled, in order to make ALTER actually work. sql/sp_head.h: Separated the different parts of the definition strings: name, parameters, return type (for functions) and body. sql/sql_yacc.yy: Separated the different parts of the definition strings: name, parameters, return type (for functions) and body. This is ugly and messy; hopefully there's a more elegant way to do this when the new parser is installed.

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/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).

Implementation of WL#2897: Complete definer support in the stored routines. The idea is to add DEFINER-clause in CREATE PROCEDURE and CREATE FUNCTION statements. Almost all support of definer in stored routines had been already done before this patch. NOTE: this patch changes behaviour of dumping stored routines in mysqldump. Before this patch, mysqldump did not dump DEFINER-clause for stored routines and this was documented behaviour. In order to get full information about stored routines, one should have dumped mysql.proc table. This patch changes this behaviour, so that DEFINER-clause is dumped. Since DEFINER-clause is not supported in CREATE PROCEDURE | FUNCTION statements before this patch, the clause is covered by additional version-specific comments. client/mysqldump.c: Updated the code for dumping stored routines: cover DEFINER-clause into version-specific comment. mysql-test/r/gis.result: Updated result file after adding DEFINER-clause. mysql-test/r/information_schema.result: Updated result file after adding DEFINER-clause. mysql-test/r/mysqldump.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_ddl.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_sp.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_trigger.result: Updated result file after adding DEFINER-clause. mysql-test/r/sp-security.result: Updated result file after adding DEFINER-clause. mysql-test/r/sp.result: Updated result file after adding DEFINER-clause. mysql-test/r/sql_mode.result: Updated result file after adding DEFINER-clause. mysql-test/t/sp-security.test: Updated result file after adding DEFINER-clause. sql/sp.cc: Added DEFINER-clause. sql/sp_head.cc: Added a new convenient variant of set_definer() operation. sql/sp_head.h: Updated result file after adding DEFINER-clause. sql/sql_lex.h: Renamed trigger_definition_begin into stmt_definition_begin to be used for triggers and stored routines. sql/sql_parse.cc: Check DEFINER-clause. sql/sql_trigger.cc: Renamed trigger_definition_begin into stmt_definition_begin to be used for triggers and stored routines. sql/sql_yacc.yy: Added DEFINER-clause.

Implementation of WL#2897: Complete definer support in the stored routines. The idea is to add DEFINER-clause in CREATE PROCEDURE and CREATE FUNCTION statements. Almost all support of definer in stored routines had been already done before this patch. NOTE: this patch changes behaviour of dumping stored routines in mysqldump. Before this patch, mysqldump did not dump DEFINER-clause for stored routines and this was documented behaviour. In order to get full information about stored routines, one should have dumped mysql.proc table. This patch changes this behaviour, so that DEFINER-clause is dumped. Since DEFINER-clause is not supported in CREATE PROCEDURE | FUNCTION statements before this patch, the clause is covered by additional version-specific comments. client/mysqldump.c: Updated the code for dumping stored routines: cover DEFINER-clause into version-specific comment. mysql-test/r/gis.result: Updated result file after adding DEFINER-clause. mysql-test/r/information_schema.result: Updated result file after adding DEFINER-clause. mysql-test/r/mysqldump.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_ddl.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_sp.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_trigger.result: Updated result file after adding DEFINER-clause. mysql-test/r/sp-security.result: Updated result file after adding DEFINER-clause. mysql-test/r/sp.result: Updated result file after adding DEFINER-clause. mysql-test/r/sql_mode.result: Updated result file after adding DEFINER-clause. mysql-test/t/sp-security.test: Updated result file after adding DEFINER-clause. sql/sp.cc: Added DEFINER-clause. sql/sp_head.cc: Added a new convenient variant of set_definer() operation. sql/sp_head.h: Updated result file after adding DEFINER-clause. sql/sql_lex.h: Renamed trigger_definition_begin into stmt_definition_begin to be used for triggers and stored routines. sql/sql_parse.cc: Check DEFINER-clause. sql/sql_trigger.cc: Renamed trigger_definition_begin into stmt_definition_begin to be used for triggers and stored routines. sql/sql_yacc.yy: Added DEFINER-clause.

Approximative fixes for BUG#2610,2611,9100 i.e. WL#2146 binlogging/replication of routines (stored procs and functions). Approximative, because it's using our binlogging way (what we call "query"-level) and this is not as good as record-level binlog (5.1) would be. It imposes several limitations to routines, and has caveats (which I'll document, and for which the server will try to issue errors but that is not always possible). Reason I don't propagate caller info to the binlog as planned is that on master and slave users may be different; even with that some caveats would remain. mysql-test/mysql-test-run.sh: In the testsuite we know what we do, we are not creating nasty routines, and breaking binlog is ok except in rpl_sp. mysql-test/r/blackhole.result: Updating results now that 4.1 has been merged mysql-test/valgrind.supp: Some suppressions for Valgrind (useful on my machine Suse 9.1); this is just adding to the already existing suppressions of pthread and dl. sql/item_func.cc: Don't binlog the substatements when executing a function. If the function is declared to modify data and does not complete, warning "broken binlog". Note that SELECT myfunc() will not be binlogged even if myfunc() updates data (will be documented); but INSERT INTO t VALUES(myfunc()) will be binlogged (what decides is if the caller gets binlogged; the function changes nothing to binlogging). sql/log_event.cc: Just making functions which can be re-used when we binlog more strings in status_vars in Query_log_event (e.g. one day "user", "host"). sql/log_event.h: comment sql/mysql_priv.h: --log-bin-trust-routine-creators sql/mysqld.cc: --log-bin-trust-routine-creators sql/set_var.cc: --log-bin-trust-routine-creators sql/share/errmsg.txt: error messages to warn about problems with routines and binlog sql/slave.cc: If in a routine, replication table inclusion/exclusion rules always answer "replicate!" (see comment in code). sql/sp.cc: If binlog is on: errors if one wants to create a non-deterministic update routine (repeatability problem - note that the test is not perfect for functions) or does not have SUPER (because routines can easily be made to destroy slave's data with just CREATE ROUTINE and EXECUTE priv on master). --log-bin-trust-routine-creators removes these errors.

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/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.

Bug #14262: SP: DROP PROCEDURE|VIEW (maybe more) write to binlog too late \ (race cond) It was possible for one thread to interrupt a Data Definition Language statement and thereby get messages to the binlog out of order. Consider: Connection 1: Drop Foo x Connection 2: Create or replace Foo x Connection 2: Log "Create or replace Foo x" Connection 1: Log "Drop Foo x" Local end would have Foo x, but the replicated slaves would not. The fix for this is to wrap all DDL and logging of a kind in the same mutex. Since we already use mutexes for the various parts of altering the server, this only entails moving the logging events down close to the action, inside the mutex protection.

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/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.

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()/...

Most of the groundwork for sprint task 729 (implement FUNCTIONs). Expanded the mysql.proc table, reworked the find/create/drop functions completely, added new functions for FUNCTIONs (lotta functions here :), got rid of some unnecessary use of Item_strings while at it. Extended the parser correspondingly, and fiddled around a bit to make SP FUNCTIONs coexist with UDFs. Can now CREATE and DROP FUNCTIONs. Invoking yet to come... Docs/sp-implemented.txt: Updated with info about CASCADE/RESTICT and METHOD, and some answers to questions. include/mysqld_error.h: New error message for misuse of RETURN. mysql-test/install_test_db.sh: Added enum field to mysql.proc to distinguish between FUNCTION and PROCEDURE. mysql-test/r/sp.result: New test for creating and dropping FUNCTIONS. mysql-test/t/sp.test: New test for creating and dropping FUNCTIONS. scripts/mysql_install_db.sh: Added enum field to mysql.proc to distinguish between FUNCTION and PROCEDURE. sql/lex.h: De-UDFed some symbol names, as they are now used for SPs as well.

Bug #14262: SP: DROP PROCEDURE|VIEW (maybe more) write to binlog too late \ (race cond) It was possible for one thread to interrupt a Data Definition Language statement and thereby get messages to the binlog out of order. Consider: Connection 1: Drop Foo x Connection 2: Create or replace Foo x Connection 2: Log "Create or replace Foo x" Connection 1: Log "Drop Foo x" Local end would have Foo x, but the replicated slaves would not. The fix for this is to wrap all DDL and logging of a kind in the same mutex. Since we already use mutexes for the various parts of altering the server, this only entails moving the logging events down close to the action, inside the mutex protection.

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/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).

Bug #14262: SP: DROP PROCEDURE|VIEW (maybe more) write to binlog too late \ (race cond) It was possible for one thread to interrupt a Data Definition Language statement and thereby get messages to the binlog out of order. Consider: Connection 1: Drop Foo x Connection 2: Create or replace Foo x Connection 2: Log "Create or replace Foo x" Connection 1: Log "Drop Foo x" Local end would have Foo x, but the replicated slaves would not. The fix for this is to wrap all DDL and logging of a kind in the same mutex. Since we already use mutexes for the various parts of altering the server, this only entails moving the logging events down close to the action, inside the mutex protection.

First stage of table definition cache Split TABLE to TABLE and TABLE_SHARE (TABLE_SHARE is still allocated as part of table, will be fixed soon) Created Field::make_field() and made Field_num::make_field() to call this Added 'TABLE_SHARE->db' that points to database name; Changed all usage of table_cache_key as database name to use this instead Changed field->table_name to point to pointer to alias. This allows us to change alias for a table by just updating one pointer.

Port of cursors to be pushed into 5.0 tree: - client side part is simple and may be considered stable - server side part now just joggles with THD state to save execution state and has no additional locking wisdom. Lot's of it are to be rewritten. include/mysql.h: Cursor patch to push into the main tree, client library part (considered stable): - new statement attribute STMT_ATTR_CURSOR_TYPE - MYSQL_STMT::flags to store statement cursor type - MYSQL_STMT::server_status to store server status (i. e. if the server was able to open a cursor for this query). include/mysql_com.h: Cursor patch to push into the main tree, client library part (considered stable): - new COMmand, COM_FETCH, to fetch K rows from read-only cursor. By design should support scrollable cursors as well. - a few new server statuses: SERVER_STATUS_CURSOR_EXISTS is sent by server in reply to COM_EXECUTE, when cursor was successfully opened for this query SERVER_STATUS_LAST_ROW_SENT is sent along with the last row to prevent one more round trip just for finding out that all rows were fetched from this cursor (this is server mem savier also). - and finally, all possible values of STMT_ATTR_CURSOR_TYPE, while now we support only CURSORT_TYPE_NO_CURSOR and CURSOR_TYPE_READ_ONLY libmysql/libmysql.c: Cursor patch to push into the main tree, client library part (considered stable): - simple additions to mysql_stmt_fetch implementation to read data from an opened cursor: we can read up to iteration count rows per one request; read rows are buffered in the same way as rows of mysql_stmt_store_result. - now send stmt->flags to server to let him now if we wish to have a cursor for this statement. - support for setting/getting statement cursor type. libmysqld/examples/Makefile.am: Testing cursors was originally implemented in C++. Now when these tests go into client_test, it's time to convert it to C++ as well. libmysqld/lib_sql.cc: - cleanup: send_fields flags are now named. sql/ha_innodb.cc: - cleanup: send_fields flags are now named. sql/mysql_priv.h: - cursors support: declaration for server-side handler of COM_FETCH sql/protocol.cc: - cleanup: send_fields flags are now named. - we can't anymore assert that field_types[field_pos] is sensible: if we have COM_EXCUTE(stmt1), COM_EXECUTE(stmt2), COM_FETCH(stmt1) field_types[field_pos] will point to fields of stmt2. sql/protocol.h: - cleanup: send_fields flag_s_ are now named. sql/protocol_cursor.cc: - cleanup: send_fields flags are now named. sql/repl_failsafe.cc: - cleanup: send_fields flags are now named. sql/slave.cc: - cleanup: send_fields flags are now named. sql/sp.cc: - cleanup: send_fields flags are now named. sql/sp_head.cc: - cleanup: send_fields flags are now named. sql/sql_acl.cc: - cleanup: send_fields flags are now named. sql/sql_class.cc: - cleanup: send_fields flags are now named. sql/sql_class.h: - cleanup: send_fields flags are now named. sql/sql_error.cc: - cleanup: send_fields flags are now named. sql/sql_handler.cc: - cleanup: send_fields flags are now named. sql/sql_help.cc: - cleanup: send_fields flags are now named. sql/sql_parse.cc: Server side support for cursors: - handle COM_FETCH - enforce assumption that whenever we free thd->free_list, we reset it to zero. This way it's much easier to handle free_list in prepared statements implementation. sql/sql_prepare.cc: Server side support for cursors: - implementation of mysql_stmt_fetch (fetch some rows from open cursor). - management of cursors memory is quite tricky now. - execute_stmt can't be reused anymore in mysql_stmt_execute and mysql_sql_stmt_execute sql/sql_repl.cc: - cleanup: send_fields flags are now named. sql/sql_select.cc: Server side support for cursors: - implementation of Cursor::open, Cursor::fetch (buggy when it comes to non-equi joins), cursor cleanups. - -4 -3 -0 constants indicating return value of sub_select and end_send are to be renamed to something more readable: it turned out to be not so simple, so it should come with the other patch. sql/sql_select.h: Server side support for cursors: - declaration of Cursor class. - JOIN::fetch_limit contains runtime value of rows fetched via cursor. sql/sql_show.cc: - cleanup: send_fields flags are now named. sql/sql_table.cc: - cleanup: send_fields flags are now named. sql/sql_union.cc: - if there was a cursor, don't cleanup unit: we'll need it to fetch the rest of the rows. tests/Makefile.am: Now client_test is in C++. tests/client_test.cc: A few elementary tests for cursors. BitKeeper/etc/ignore: Added libmysqld/examples/client_test.cc to the ignore list

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. NOTICE: - This patch is not complete in the sense that - there are 2 test cases that still do not pass - one in join.test, one in select.test. Both are marked with a comment "TODO: WL#2486". - it does not include a new test specific for the task mysql-test/include/ps_query.inc: Adjusted according to standard NATURAL/USING join semantics., mysql-test/r/bdb.result: Adjusted according to standard NATURAL/USING join semantics. mysql-test/r/derived.result: Adjusted according to standard NATURAL/USING join semantics. mysql-test/r/errors.result: The column as a whole cannot be resolved, so different error message. mysql-test/r/fulltext.result: Adjusted according to standard JOIN ...

There is one find_field_in_XXX procedure per each type of table reference (stored table, merge view, or natural join); one meta-procedure that selects the correct one depeneding on the table reference; and one procedure that goes over a list of table referenes. - NATURAL/USING joins are processed through the procedures: mark_common_columns, store_natural_using_join_columns, store_top_level_join_columns, setup_natural_join_row_types. The entry point to processing NATURAL/USING joins is the procedure 'setup_natural_join_row_types'. - Replaced the specialized Field_iterator_XXX iterators with one generic iterator over the fields of a table reference. - Simplified 'insert_fields' and 'setup_conds' due to encapsulation of the processing of natural joins in a separate set of procedures. sql/sql_class.h: - Commented old code. sql/sql_delete.cc: - Pass the FROM clause to setup_tables. sql/sql_help.cc: - pass the end name resolution table to find_field_in_tables - adjust the list of tables for name resolution sql/sql_insert.cc: - Changed the code that saves and restores the current context to support the list of tables for name resolution - context->first_name_resolution_table, and table_list->next_name_resolution_table. Needed to support an ugly trick to resolve inserted columns only in the first table. - Added Name_resolution_context::[first | last]_name_resolution_table. - Commented old code sql/sql_lex.cc: - set select_lex.parent_lex correctly - set correct state of the current name resolution context sql/sql_lex.h: - Added a stack of name resolution contexts to support local contexts for JOIN ... ON conditions. - Commented old code. sql/sql_load.cc: - Pass the FROM clause to setup_tables. sql/sql_olap.cc: - Pass the FROM clause to setup_tables. sql/sql_parse.cc: - correctly set SELECT_LEX::parent_lex - set the first table of the current name resoltion context - added support for NATURAL/USING joins - commented old code sql/sql_select.cc: - Pass the FROM clause to setup_tables. - Pass the end table to find_field_in_tables - Improved comments sql/sql_show.cc: - Set SELECT_LEX::parent_lex. sql/sql_update.cc: - Pass the FROM clause to setup_tables. sql/sql_yacc.yy: - Added support for a stack of name resolution contexts needed to implement name resolution for JOIN ... ON. A context is pushed for each new JOIN ... ON, and popped afterwards. - Added support for NATURAL/USING joins. sql/table.cc: - Added new class Natural_join_column to hide the heterogeneous representation of column references for stored tables and for views. - Added a new list TABLE_LIST::next_name_resolution_table to support name resolution with NATURAL/USING joins. Also added other members to TABLE_LIST to support NATURAL/USING joins. - Added a generic iterator over the fields of table references of various types - class Field_iterator_table_ref sql/table.h: - Added new class Natural_join_column to hide the heterogeneous representation of column references for stored tables and for views. - Added a new list TABLE_LIST::next_name_resolution_table to support name resolution with NATURAL/USING joins.

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. NOTICE: - This patch is not complete in the sense that - there are 2 test cases that still do not pass - one in join.test, one in select.test. Both are marked with a comment "TODO: WL#2486". - it does not include a new test specific for the task mysql-test/include/ps_query.inc: Adjusted according to standard NATURAL/USING join semantics., mysql-test/r/bdb.result: Adjusted according to standard NATURAL/USING join semantics. mysql-test/r/derived.result: Adjusted according to standard NATURAL/USING join semantics. mysql-test/r/errors.result: The column as a whole cannot be resolved, so different error message. mysql-test/r/fulltext.result: Adjusted according to standard JOIN ...

There is one find_field_in_XXX procedure per each type of table reference (stored table, merge view, or natural join); one meta-procedure that selects the correct one depeneding on the table reference; and one procedure that goes over a list of table referenes. - NATURAL/USING joins are processed through the procedures: mark_common_columns, store_natural_using_join_columns, store_top_level_join_columns, setup_natural_join_row_types. The entry point to processing NATURAL/USING joins is the procedure 'setup_natural_join_row_types'. - Replaced the specialized Field_iterator_XXX iterators with one generic iterator over the fields of a table reference. - Simplified 'insert_fields' and 'setup_conds' due to encapsulation of the processing of natural joins in a separate set of procedures. sql/sql_class.h: - Commented old code. sql/sql_delete.cc: - Pass the FROM clause to setup_tables. sql/sql_help.cc: - pass the end name resolution table to find_field_in_tables - adjust the list of tables for name resolution sql/sql_insert.cc: - Changed the code that saves and restores the current context to support the list of tables for name resolution - context->first_name_resolution_table, and table_list->next_name_resolution_table. Needed to support an ugly trick to resolve inserted columns only in the first table. - Added Name_resolution_context::[first | last]_name_resolution_table. - Commented old code sql/sql_lex.cc: - set select_lex.parent_lex correctly - set correct state of the current name resolution context sql/sql_lex.h: - Added a stack of name resolution contexts to support local contexts for JOIN ... ON conditions. - Commented old code. sql/sql_load.cc: - Pass the FROM clause to setup_tables. sql/sql_olap.cc: - Pass the FROM clause to setup_tables. sql/sql_parse.cc: - correctly set SELECT_LEX::parent_lex - set the first table of the current name resoltion context - added support for NATURAL/USING joins - commented old code sql/sql_select.cc: - Pass the FROM clause to setup_tables. - Pass the end table to find_field_in_tables - Improved comments sql/sql_show.cc: - Set SELECT_LEX::parent_lex. sql/sql_update.cc: - Pass the FROM clause to setup_tables. sql/sql_yacc.yy: - Added support for a stack of name resolution contexts needed to implement name resolution for JOIN ... ON. A context is pushed for each new JOIN ... ON, and popped afterwards. - Added support for NATURAL/USING joins. sql/table.cc: - Added new class Natural_join_column to hide the heterogeneous representation of column references for stored tables and for views. - Added a new list TABLE_LIST::next_name_resolution_table to support name resolution with NATURAL/USING joins. Also added other members to TABLE_LIST to support NATURAL/USING joins. - Added a generic iterator over the fields of table references of various types - class Field_iterator_table_ref sql/table.h: - Added new class Natural_join_column to hide the heterogeneous representation of column references for stored tables and for views. - Added a new list TABLE_LIST::next_name_resolution_table to support name resolution with NATURAL/USING joins. Also added other members to TABLE_LIST to support NATURAL/USING joins. - Added a generic iterator over the fields of table references of various types - class Field_iterator_table_ref tests/mysql_client_test.c: Adjusted according to standard NATURAL JOIN syntax.

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. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Replaced wrong results of test for bug #5240 with correct results after fixing bug in handling of cursors. mysql-test/t/lock.test: Replaced wrong error code with the correct one after fixing bug in SP-locking. mysql-test/t/mysqldump.test: Added dropping of view which is used in test to its beginning. mysql-test/t/sp.test: Added tests for improved SP-locking. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Removed test for bug #1654 since we already test exactly this function in one of SP-locking tests. Removed comment about cursor's wrong behavior in test for bug #5240 after fixing bug which was its cause. sql/item_func.cc: Removed comment which is no longer true. sql/mysql_priv.h: Changed open_tables() signature. 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.

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.

sp_find_routine()
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. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Replaced wrong results of test for bug #5240 with correct results after fixing bug in handling of cursors. mysql-test/t/lock.test: Replaced wrong error code with the correct one after fixing bug in SP-locking. mysql-test/t/mysqldump.test: Added dropping of view which is used in test to its beginning. mysql-test/t/sp.test: Added tests for improved SP-locking. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Removed test for bug #1654 since we already test exactly this function in one of SP-locking tests. Removed comment about cursor's wrong behavior in test for bug #5240 after fixing bug which was its cause. sql/item_func.cc: Removed comment which is no longer true. sql/mysql_priv.h: Changed open_tables() signature. 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.

type - type of object (TYPE_ENUM_FUNCTION or TYPE_ENUM_PROCEDURE)
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. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Replaced wrong results of test for bug #5240 with correct results after fixing bug in handling of cursors. mysql-test/t/lock.test: Replaced wrong error code with the correct one after fixing bug in SP-locking. mysql-test/t/mysqldump.test: Added dropping of view which is used in test to its beginning. mysql-test/t/sp.test: Added tests for improved SP-locking. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Removed test for bug #1654 since we already test exactly this function in one of SP-locking tests. Removed comment about cursor's wrong behavior in test for bug #5240 after fixing bug which was its cause. sql/item_func.cc: Removed comment which is no longer true. sql/mysql_priv.h: Changed open_tables() signature. 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.

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.

Fix for BUG#16211: Stored function return type for strings is ignored. Fix for BUG#16676: Database CHARSET not used for stored procedures The problem in BUG#16211 is that CHARSET-clause of the return type for stored functions is just ignored. The problem in BUG#16676 is that if character set is not explicitly specified for sp-variable, the server character set is used instead of the database one. The fix has two parts: - always store CHARSET-clause of the return type along with the type definition in mysql.proc.returns column. "Always" means that CHARSET-clause is appended even if it has not been explicitly specified in CREATE FUNCTION statement (this affects BUG#16211 only). Storing CHARSET-clause if it is not specified is essential to avoid changing character set if the database character set is altered in the future. NOTE: this change is not backward compatible with the previous releases. - use database default character set if CHARSET-clause is not explicitly specified (this affects both BUG#16211 and BUG#16676). NOTE: this also breaks backward compatibility. mysql-test/r/mysqldump.result: Updated result file. mysql-test/r/sp.result: Updated result file. mysql-test/t/sp.test: Provided test cases for BUG#16211, BUG#16676. sql/mysql_priv.h: Added two convenient functions for work with databases. sql/sp.cc: 1. Add CHARSET-clause to CREATE-statement if it has been explicitly specified. 2. Polishing -- provided some comments. sql/sp_head.cc: Use database charset as default charset of sp-variable. sql/sp_head.h: Move init_sp_name() out of init_strings(). sql/sql_db.cc: Two new functions created: - load_db_opt_by_name(); - check_db_dir_existence(); sql/sql_show.cc: Eliminate duplicated code by using check_db_dir_existence() and load_db_opt_by_name() sql/sql_table.cc: Eliminate duplicated code by using check_db_dir_existence() and load_db_opt_by_name() sql/sql_yacc.yy: Call sp_head::init_sp_name() to initialize stored routine name.

Most of the groundwork for sprint task 729 (implement FUNCTIONs). Expanded the mysql.proc table, reworked the find/create/drop functions completely, added new functions for FUNCTIONs (lotta functions here :), got rid of some unnecessary use of Item_strings while at it. Extended the parser correspondingly, and fiddled around a bit to make SP FUNCTIONs coexist with UDFs. Can now CREATE and DROP FUNCTIONs. Invoking yet to come...

(And got rid of some unnecessary Item_string use.) sql/sql_lex.h: New stored FUNCTION commands. sql/sql_parse.cc: Added FUNCTION support ("drop" merged with the old UDF code), and made some additional changes for better error handling (following the sp.cc rehacking). sql/sql_yacc.yy: Some former UDF specific symbols renamed. Added CREATE FUNCTION parsing. DROP FUNCTION had to be partly merged with the old UDF code, because of the similar syntax. RETURN statement added, but still a no-op.

Most of the groundwork for sprint task 729 (implement FUNCTIONs).

In order to make ALTER PROCEDURE|FUNCTION work correctly, and in general to make characteristics (and SHOW) work right, we had to separate the old definition blob in the mysql.proc table into separate fields for parameters, return type, and body, and handle the characteristics (like SQL SECURITY) separately... and then reassemble the CREATE string for parsing, of course. This is rather ugly, mostly the parser bit. (Hopefully that will be better with the new parser.) Docs/sp-imp-spec.txt: Separated the definitions string of the procedure into different columns in the mysql.proc schema. mysql-test/r/sp.result: New characteristics tests. mysql-test/t/sp.test: New characteristics tests. scripts/mysql_create_system_tables.sh: Separated the definitions string of the procedure into different columns in the mysql.proc schema. scripts/mysql_fix_privilege_tables.sql: Separated the definitions string of the procedure into different columns in the mysql.proc schema. sql/sp.cc: Separated the definitions string of the procedure into different columns. Rewrote much of the code related this (have a assemble the definition string from its different parts now) and the way characteristics are now handled, in order to make ALTER actually work. sql/sp.h: Changed prototypes. sql/sp_head.cc: Rewrote much of the code related to the new mysql.proc schema with separate definition fields (have to assemble the definition string from its different parts now) and the way characteristics are now handled, in order to make ALTER actually work. sql/sp_head.h: Separated the different parts of the definition strings: name, parameters, return type (for functions) and body. sql/sql_yacc.yy: Separated the different parts of the definition strings: name, parameters, return type (for functions) and body. This is ugly and messy; hopefully there's a more elegant way to do this when the new parser is installed.

Fix for BUG#12228: SP cache code: * Cleanup SP Cache code, now SP Cache only deletes sp_head objects in sp_cache_flush_obsolete() invalidates all pointers to routines in the cache. * Use new SP Cache use contract in the code. There is no test case because it doesn't seem to be possible to cause thread races to end the same way they end in heavy-load test. This patch removes the crash in heavy test. mysql-test/r/type_bit.result: Drop the tables this test tries to create mysql-test/r/view.result: Drop function this test creates mysql-test/t/type_bit.test: Drop the tables this test tries to create mysql-test/t/view.test: Drop function this test creates sql/sp.cc: Fix for BUG#12228: When a routine is deleted/modified, invalidate all cached SPs in all threads. We need to do so because sp_lex_keeper::{prelocking_tables, query_tables_own_last} in one SP may depend on another SP sp_lex_keeper::m_lex is using. sql/sp_cache.cc: Fix for BUG#12228: * Move class sp_cache to here from sp_cache.h, document the functions. * sp_cache_insert, sp_cache_remove, sp_cache_invalidate and sp_cache_lookup must not delete sp_head* objects as they may be called during SP execution when sp_head objects are used. * Added sp_cache_flush_obsolete() function that may delete sp_head objects. * Removed sp_cache_remove as there is no need for it now - when we change one SP we should invalidate all other SPs, because sp_lex_keeper::{prelocking_tables, query_tables_own_last} from one SP depend on content of another SP (used in sp_lex_keeper::m_lex). sql/sp_cache.h: Fix for BUG#12228: * Move class sp_cache to sp_cache.cc it is not needed in .h file * Added comments sql/sql_parse.cc: Fix for BUG#12228: Call new sp_cache_flush_obsolete() function before running the query sql/sql_prepare.cc: Fix for BUG#12228: Call new sp_cache_flush_obsolete() function before preparing/executing a PS

In order to make ALTER PROCEDURE|FUNCTION work correctly, and in general to make characteristics (and SHOW) work right, we had to separate the old definition blob in the mysql.proc table into separate fields for parameters, return type, and body, and handle the characteristics (like SQL SECURITY) separately... and then reassemble the CREATE string for parsing, of course. This is rather ugly, mostly the parser bit. (Hopefully that will be better with the new parser.) Docs/sp-imp-spec.txt: Separated the definitions string of the procedure into different columns in the mysql.proc schema. mysql-test/r/sp.result: New characteristics tests. mysql-test/t/sp.test: New characteristics tests. scripts/mysql_create_system_tables.sh: Separated the definitions string of the procedure into different columns in the mysql.proc schema. scripts/mysql_fix_privilege_tables.sql: Separated the definitions string of the procedure into different columns in the mysql.proc schema. sql/sp.cc: Separated the definitions string of the procedure into different columns. Rewrote much of the code related this (have a assemble the definition string from its different parts now) and the way characteristics are now handled, in order to make ALTER actually work. sql/sp.h: Changed prototypes. sql/sp_head.cc: Rewrote much of the code related to the new mysql.proc schema with separate definition fields (have to assemble the definition string from its different parts now) and the way characteristics are now handled, in order to make ALTER actually work. sql/sp_head.h: Separated the different parts of the definition strings: name, parameters, return type (for functions) and body. sql/sql_yacc.yy: Separated the different parts of the definition strings: name, parameters, return type (for functions) and body. This is ugly and messy; hopefully there's a more elegant way to do this when the new parser is installed.

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.

Fix for bug #11555 "Stored procedures: current SP tables locking make impossible view security". We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing. So during building of list of prelocked tables for statement we track which routines (and therefore tables for these routines) are used from views. We mark elements of LEX::routines set which correspond to routines used in views by setting Sroutine_hash_entry::belong_to_view member to point to TABLE_LIST object for topmost view which uses routine. We propagate this mark to all routines which are used by this routine and which we add to this set.

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.

NOTES
This function assumes that for any "CALL proc(...)" statement routines_list
will have 'proc' as first element (it may have several, consider e.g.
"proc(sp_func(...)))". This property is currently guaranted by the parser.

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.

Auxilary function that adds new element to the set of stored routines

SYNOPSIS
add_used_routine()
Fix for bug #11555 "Stored procedures: current SP tables locking make impossible view security". We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing. So during building of list of prelocked tables for statement we track which routines (and therefore tables for these routines) are used from views. We mark elements of LEX::routines set which correspond to routines used in views by setting Sroutine_hash_entry::belong_to_view member to point to TABLE_LIST object for topmost view which uses routine. We propagate this mark to all routines which are used by this routine and which we add to this set. We also mark tables used by such routine which we add to the list of tables for prelocking as belonging to this view. mysql-test/r/sp-error.result: Added test for bug #11555 "Stored procedures: current SP tables locking make impossible view security". mysql-test/r/view.result: We should not expose tables which are expicitly/implicitly used in view in check table statement. mysql-test/t/sp-error.test: Added test for bug #11555 "Stored procedures: current SP tables locking make impossible view security". mysql-test/t/view.test: Removed comment obsoleted by bugfix. sql/sp.cc: We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing.

NOTES
Will also add element to end of 'LEX::sroutines_list' list.
In case when statement uses stored routines but does not need
prelocking (i.e. it does not use any tables) we will access the
elements of LEX::sroutines set on prepared statement re-execution.
Because of this we have to allocate memory for both hash element
and copy of its key in persistent arena.
TODO
When we will got rid of these accesses on re-executions we will be
able to allocate memory for hash elements in non-persitent arena
and directly use key values from sp_head::m_sroutines sets instead
of making their copies.
RETURN VALUE
TRUE - new element was added.
FALSE - element was not added (because it is already present in the set).

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.

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.

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.

Fix for bug #11555 "Stored procedures: current SP tables locking make impossible view security". We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing. So during building of list of prelocked tables for statement we track which routines (and therefore tables for these routines) are used from views. We mark elements of LEX::routines set which correspond to routines used in views by setting Sroutine_hash_entry::belong_to_view member to point to TABLE_LIST object for topmost view which uses routine.

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.

/*
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.

Add routine which is explicitly used by statement to the set of stored
routines used by this statement.
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. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Replaced wrong results of test for bug #5240 with correct results after fixing bug in handling of cursors. mysql-test/t/lock.test: Replaced wrong error code with the correct one after fixing bug in SP-locking. mysql-test/t/mysqldump.test: Added dropping of view which is used in test to its beginning. mysql-test/t/sp.test: Added tests for improved SP-locking. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Removed test for bug #1654 since we already test exactly this function in one of SP-locking tests. Removed comment about cursor's wrong behavior in test for bug #5240 after fixing bug which was its cause. sql/item_func.cc: Removed comment which is no longer true. sql/mysql_priv.h: Changed open_tables() signature. 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.

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.

SYNOPSIS
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.

NOTES
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.

Will also add element to end of 'LEX::sroutines_list' list (and will
take into account that this is explicitly used routine).
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.

Fix for bug #11555 "Stored procedures: current SP tables locking make impossible view security". We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing. So during building of list of prelocked tables for statement we track which routines (and therefore tables for these routines) are used from views. We mark elements of LEX::routines set which correspond to routines used in views by setting Sroutine_hash_entry::belong_to_view member to point to TABLE_LIST object for topmost view which uses routine. We propagate this mark to all routines which are used by this routine and which we add to this set. We also mark tables used by such routine which we add to the list of tables for prelocking as belonging to this view. mysql-test/r/sp-error.result: Added test for bug #11555 "Stored procedures: current SP tables locking make impossible view security". mysql-test/r/view.result: We should not expose tables which are expicitly/implicitly used in view in check table statement. mysql-test/t/sp-error.test: Added test for bug #11555 "Stored procedures: current SP tables locking make impossible view security". mysql-test/t/view.test: Removed comment obsoleted by bugfix. sql/sp.cc: We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing.

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.

SYNOPSIS
sp_update_sp_used_routines()
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. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Replaced wrong results of test for bug #5240 with correct results after fixing bug in handling of cursors. mysql-test/t/lock.test: Replaced wrong error code with the correct one after fixing bug in SP-locking. mysql-test/t/mysqldump.test: Added dropping of view which is used in test to its beginning. mysql-test/t/sp.test: Added tests for improved SP-locking. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Removed test for bug #1654 since we already test exactly this function in one of SP-locking tests. Removed comment about cursor's wrong behavior in test for bug #5240 after fixing bug which was its cause. sql/item_func.cc: Removed comment which is no longer true. sql/mysql_priv.h: Changed open_tables() signature. 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.

dst - hash to which elements should be added
src - hash from which elements merged
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.

NOTE
This procedure won't create new Sroutine_hash_entry objects,
instead it will simply add elements from source to destination
hash. Thus time of life of elements in destination hash becomes
dependant on time of life of elements from source hash. It also
won't touch lists linking elements in source and destination
hashes.
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. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Replaced wrong results of test for bug #5240 with correct results after fixing bug in handling of cursors. mysql-test/t/lock.test: Replaced wrong error code with the correct one after fixing bug in SP-locking. mysql-test/t/mysqldump.test: Added dropping of view which is used in test to its beginning. mysql-test/t/sp.test: Added tests for improved SP-locking. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Removed test for bug #1654 since we already test exactly this function in one of SP-locking tests. Removed comment about cursor's wrong behavior in test for bug #5240 after fixing bug which was its cause. sql/item_func.cc: Removed comment which is no longer true. sql/mysql_priv.h: Changed open_tables() signature. 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".

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.

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.

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.

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.

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. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Replaced wrong results of test for bug #5240 with correct results after fixing bug in handling of cursors. mysql-test/t/lock.test: Replaced wrong error code with the correct one after fixing bug in SP-locking. mysql-test/t/mysqldump.test: Added dropping of view which is used in test to its beginning. mysql-test/t/sp.test: Added tests for improved SP-locking. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Removed test for bug #1654 since we already test exactly this function in one of SP-locking tests. Removed comment about cursor's wrong behavior in test for bug #5240 after fixing bug which was its cause. sql/item_func.cc: Removed comment which is no longer true. sql/mysql_priv.h: Changed open_tables() signature. 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.

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.
2005-07-09 19:51:59 +02:00
Add contents of hash representing set of routines to the set of
routines used by statement.
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. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Replaced wrong results of test for bug #5240 with correct results after fixing bug in handling of cursors. mysql-test/t/lock.test: Replaced wrong error code with the correct one after fixing bug in SP-locking. mysql-test/t/mysqldump.test: Added dropping of view which is used in test to its beginning. mysql-test/t/sp.test: Added tests for improved SP-locking. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Removed test for bug #1654 since we already test exactly this function in one of SP-locking tests. Removed comment about cursor's wrong behavior in test for bug #5240 after fixing bug which was its cause. sql/item_func.cc: Removed comment which is no longer true. sql/mysql_priv.h: Changed open_tables() signature. 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.

sp_update_stmt_used_routines()
Fix for bug #11555 "Stored procedures: current SP tables locking make impossible view security". We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing. So during building of list of prelocked tables for statement we track which routines (and therefore tables for these routines) are used from views. We mark elements of LEX::routines set which correspond to routines used in views by setting Sroutine_hash_entry::belong_to_view member to point to TABLE_LIST object for topmost view which uses routine. We propagate this mark to all routines which are used by this routine and which we add to this set. We also mark tables used by such routine which we add to the list of tables for prelocking as belonging to this view. mysql-test/r/sp-error.result: Added test for bug #11555 "Stored procedures: current SP tables locking make impossible view security". mysql-test/r/view.result: We should not expose tables which are expicitly/implicitly used in view in check table statement. mysql-test/t/sp-error.test: Added test for bug #11555 "Stored procedures: current SP tables locking make impossible view security". mysql-test/t/view.test: Removed comment obsoleted by bugfix. sql/sp.cc: We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing. So during building of list of prelocked tables for statement we track which routines (and therefore tables for these routines) are used from views.

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.

Fix for bug #11555 "Stored procedures: current SP tables locking make impossible view security". We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing. So during building of list of prelocked tables for statement we track which routines (and therefore tables for these routines) are used from views. We mark elements of LEX::routines set which correspond to routines used in views by setting Sroutine_hash_entry::belong_to_view member to point to TABLE_LIST object for topmost view which uses routine. We propagate this mark to all routines which are used by this routine and which we add to this set. We also mark tables used by such routine which we add to the list of tables for prelocking as belonging to this view. mysql-test/r/sp-error.result: Added test for bug #11555 "Stored procedures: current SP tables locking make impossible view security". mysql-test/r/view.result: We should not expose tables which are expicitly/implicitly used in view in check table statement. mysql-test/t/sp-error.test: Added test for bug #11555 "Stored procedures: current SP tables locking make impossible view security". mysql-test/t/view.test: Removed comment obsoleted by bugfix. sql/sp.cc: We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing.

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.

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.

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.

Fix for bug #11555 "Stored procedures: current SP tables locking make impossible view security".

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.

thd - thread context
lex - LEX representing statement
start - first routine from the list of routines to be cached
(this list defines mentioned sub-set).
first_no_prelock - If true, don't add tables or cache routines used by
the body of the first routine (i.e. *start)
will be executed in non-prelocked mode.
tabs_changed - Set to TRUE some tables were added, FALSE otherwise
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. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Replaced wrong results of test for bug #5240 with correct results after fixing bug in handling of cursors. mysql-test/t/lock.test: Replaced wrong error code with the correct one after fixing bug in SP-locking. mysql-test/t/mysqldump.test: Added dropping of view which is used in test to its beginning. mysql-test/t/sp.test: Added tests for improved SP-locking. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Removed test for bug #1654 since we already test exactly this function in one of SP-locking tests. Removed comment about cursor's wrong behavior in test for bug #5240 after fixing bug which was its cause. sql/item_func.cc: Removed comment which is no longer true. sql/mysql_priv.h: Changed open_tables() signature. 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.

NOTE
If some function is missing this won't be reported here.
Instead this fact will be discovered during query execution.
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.

RETURN VALUE
0 - success
non-0 - failure
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. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Replaced wrong results of test for bug #5240 with correct results after fixing bug in handling of cursors. mysql-test/t/lock.test: Replaced wrong error code with the correct one after fixing bug in SP-locking. mysql-test/t/mysqldump.test: Added dropping of view which is used in test to its beginning. mysql-test/t/sp.test: Added tests for improved SP-locking. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Removed test for bug #1654 since we already test exactly this function in one of SP-locking tests. Removed comment about cursor's wrong behavior in test for bug #5240 after fixing bug which was its cause. sql/item_func.cc: Removed comment which is no longer true. sql/mysql_priv.h: Changed open_tables() signature. 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.

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 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).

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.

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.

(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.

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.

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.

SYNOPSIS
sp_cache_routines_and_add_tables_for_view()
Fix for bug #11555 "Stored procedures: current SP tables locking make impossible view security". We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing. So during building of list of prelocked tables for statement we track which routines (and therefore tables for these routines) are used from views. We mark elements of LEX::routines set which correspond to routines used in views by setting Sroutine_hash_entry::belong_to_view member to point to TABLE_LIST object for topmost view which uses routine. We propagate this mark to all routines which are used by this routine and which we add to this set. We also mark tables used by such routine which we add to the list of tables for prelocking as belonging to this view. mysql-test/r/sp-error.result: Added test for bug #11555 "Stored procedures: current SP tables locking make impossible view security". mysql-test/r/view.result: We should not expose tables which are expicitly/implicitly used in view in check table statement. mysql-test/t/sp-error.test: Added test for bug #11555 "Stored procedures: current SP tables locking make impossible view security". mysql-test/t/view.test: Removed comment obsoleted by bugfix. sql/sp.cc: We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing. So during building of list of prelocked tables for statement we track which routines (and therefore tables for these routines) are used from views.

We propagate this mark to all routines which are used by this routine and which we add to this set. We also mark tables used by such routine which we add to the list of tables for prelocking as belonging to this view. sql/sp.h: sp_cache_routines_and_add_tables_for_view()/for_triggers(): To be able to determine correctly uppermost view which uses this view/table with trigger we have to pass pointer to TABLE_LIST object instead of pointer to view's LEX or to Table_triggers_list object. sql/sp_head.cc: sp_head::add_used_tables_to_table_list(): Added new argument which allows to mark tables which are added to table list for prelocking as belonging to view (this allows properly hide names of tables which are used in routines used by views). sql/sp_head.h: sp_head::add_used_tables_to_table_list(): Added new argument which allows to mark tables which are added to table list for prelocking as belonging to view (this allows properly hide names of tables which are used in routines used by views). sql/sql_base.cc: open_tables(): sp_cache_routines_and_add_tables_for_view()/for_triggers() now accept pointer to table list element as last argument, this allows them to determine correctly uppermost view which uses this view/table with trigger. sql/sql_trigger.h: Table_triggers_list: sp_cache_routines_and_add_tables_for_triggers() now accept pointer to table list element as last argument, this allows to determine correctly uppermost view which uses this table with trigger.

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.

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.

To support it we create special .TRN file with same name as trigger for each trigger. This file contains name of trigger's table so one does not need to specify it explicitly in DROP TRIGGER.

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.

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. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Replaced wrong results of test for bug #5240 with correct results after fixing bug in handling of cursors. mysql-test/t/lock.test: Replaced wrong error code with the correct one after fixing bug in SP-locking. mysql-test/t/mysqldump.test: Added dropping of view which is used in test to its beginning. mysql-test/t/sp.test: Added tests for improved SP-locking. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Removed test for bug #1654 since we already test exactly this function in one of SP-locking tests. Removed comment about cursor's wrong behavior in test for bug #5240 after fixing bug which was its cause. sql/item_func.cc: Removed comment which is no longer true. sql/mysql_priv.h: Changed open_tables() signature. 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.

Fix for bug #11555 "Stored procedures: current SP tables locking make impossible view security". We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing. So during building of list of prelocked tables for statement we track which routines (and therefore tables for these routines) are used from views. We mark elements of LEX::routines set which correspond to routines used in views by setting Sroutine_hash_entry::belong_to_view member to point to TABLE_LIST object for topmost view which uses routine.

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.

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.

Fix for bug #11555 "Stored procedures: current SP tables locking make impossible view security". We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing. So during building of list of prelocked tables for statement we track which routines (and therefore tables for these routines) are used from views. We mark elements of LEX::routines set which correspond to routines used in views by setting Sroutine_hash_entry::belong_to_view member to point to TABLE_LIST object for topmost view which uses routine. We propagate this mark to all routines which are used by this routine and which we add to this set. We also mark tables used by such routine which we add to the list of tables for prelocking as belonging to this view. mysql-test/r/sp-error.result: Added test for bug #11555 "Stored procedures: current SP tables locking make impossible view security". mysql-test/r/view.result: We should not expose tables which are expicitly/implicitly used in view in check table statement. mysql-test/t/sp-error.test: Added test for bug #11555 "Stored procedures: current SP tables locking make impossible view security". mysql-test/t/view.test: Removed comment obsoleted by bugfix. sql/sp.cc: We should not expose names of tables which are explicitly or implicitly (via routine or trigger) used by view even if we find that they are missing. So during building of list of prelocked tables for statement we track which routines (and therefore tables for these routines) are used from views. We mark elements of LEX::routines set which correspond to routines used in views by setting Sroutine_hash_entry::belong_to_view member to point to TABLE_LIST object for topmost view which uses routine.

We also mark tables used by such routine which we add to the list of tables for prelocking as belonging to this view. sql/sp.h: sp_cache_routines_and_add_tables_for_view()/for_triggers(): To be able to determine correctly uppermost view which uses this view/table with trigger we have to pass pointer to TABLE_LIST object instead of pointer to view's LEX or to Table_triggers_list object. sql/sp_head.cc: sp_head::add_used_tables_to_table_list(): Added new argument which allows to mark tables which are added to table list for prelocking as belonging to view (this allows properly hide names of tables which are used in routines used by views). sql/sp_head.h: sp_head::add_used_tables_to_table_list(): Added new argument which allows to mark tables which are added to table list for prelocking as belonging to view (this allows properly hide names of tables which are used in routines used by views). sql/sql_base.cc: open_tables(): sp_cache_routines_and_add_tables_for_view()/for_triggers() now accept pointer to table list element as last argument, this allows them to determine correctly uppermost view which uses this view/table with trigger. sql/sql_trigger.h: Table_triggers_list: sp_cache_routines_and_add_tables_for_triggers() now accept pointer to table list element as last argument, this allows to determine correctly uppermost view which uses this table with trigger.

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. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Replaced wrong results of test for bug #5240 with correct results after fixing bug in handling of cursors. mysql-test/t/lock.test: Replaced wrong error code with the correct one after fixing bug in SP-locking. mysql-test/t/mysqldump.test: Added dropping of view which is used in test to its beginning. mysql-test/t/sp.test: Added tests for improved SP-locking. Temporarily disabled tests for SHOW PROCEDURE STATUS and alike (Until Monty will allow to open mysql.proc under LOCK TABLES without mentioning it in lock list). Removed test for bug #1654 since we already test exactly this function in one of SP-locking tests. Removed comment about cursor's wrong behavior in test for bug #5240 after fixing bug which was its cause. sql/item_func.cc: Removed comment which is no longer true. sql/mysql_priv.h: Changed open_tables() signature. 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.

Implementation of WL#2897: Complete definer support in the stored routines. The idea is to add DEFINER-clause in CREATE PROCEDURE and CREATE FUNCTION statements. Almost all support of definer in stored routines had been already done before this patch. NOTE: this patch changes behaviour of dumping stored routines in mysqldump. Before this patch, mysqldump did not dump DEFINER-clause for stored routines and this was documented behaviour. In order to get full information about stored routines, one should have dumped mysql.proc table. This patch changes this behaviour, so that DEFINER-clause is dumped. Since DEFINER-clause is not supported in CREATE PROCEDURE | FUNCTION statements before this patch, the clause is covered by additional version-specific comments. client/mysqldump.c: Updated the code for dumping stored routines: cover DEFINER-clause into version-specific comment. mysql-test/r/gis.result: Updated result file after adding DEFINER-clause. mysql-test/r/information_schema.result: Updated result file after adding DEFINER-clause. mysql-test/r/mysqldump.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_ddl.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_sp.result: Updated result file after adding DEFINER-clause. mysql-test/r/rpl_trigger.result: Updated result file after adding DEFINER-clause. mysql-test/r/sp-security.result: Updated result file after adding DEFINER-clause. mysql-test/r/sp.result: Updated result file after adding DEFINER-clause. mysql-test/r/sql_mode.result: Updated result file after adding DEFINER-clause. mysql-test/t/sp-security.test: Updated result file after adding DEFINER-clause. sql/sp.cc: Added DEFINER-clause. sql/sp_head.cc: Added a new convenient variant of set_definer() operation. sql/sp_head.h: Updated result file after adding DEFINER-clause. sql/sql_lex.h: Renamed trigger_definition_begin into stmt_definition_begin to be used for triggers and stored routines. sql/sql_parse.cc: Check DEFINER-clause. sql/sql_trigger.cc: Renamed trigger_definition_begin into stmt_definition_begin to be used for triggers and stored routines. sql/sql_yacc.yy: Added DEFINER-clause.

A fix and a test case for Bug#19022 "Memory bug when switching db during trigger execution" Bug#17199 "Problem when view calls function from another database." Bug#18444 "Fully qualified stored function names don't work correctly in SELECT statements" Documentation note: this patch introduces a change in behaviour of prepared statements. This patch adds a few new invariants with regard to how THD::db should be used. These invariants should be preserved in future: - one should never refer to THD::db by pointer and always make a deep copy (strmake, strdup) - one should never compare two databases by pointer, but use strncmp or my_strncasecmp - TABLE_LIST object table->db should be always initialized in the parser or by creator of the object. For prepared statements it means that if the current database is changed after a statement is prepared, the database that was current at prepare remains active. This also means that you can not prepare a statement that implicitly refers to the current database if the latter is not set. This is not documented, and therefore needs documentation. This is NOT a change in behavior for almost all SQL statements except: - ALTER TABLE t1 RENAME t2 - OPTIMIZE TABLE t1 - ANALYZE TABLE t1 - TRUNCATE TABLE t1 -- until this patch t1 or t2 could be evaluated at the first execution of prepared statement. CURRENT_DATABASE() still works OK and is evaluated at every execution of prepared statement. Note, that in stored routines this is not an issue as the default database is the database of the stored procedure and "use" statement is prohibited in stored routines. This patch makes obsolete the use of check_db_used (it was never used in the old code too) and all other places that check for table->db and assign it from THD::db if it's NULL, except the parser. How this patch was created: THD::{db,db_length} were replaced with a LEX_STRING, THD::db. All the places that refer to THD::{db,db_length} were manually checked and: - if the place uses thd->db by pointer, it was fixed to make a deep copy - if a place compared two db pointers, it was fixed to compare them by value (via strcmp/my_strcasecmp, whatever was approproate) Then this intermediate patch was used to write a smaller patch that does the same thing but without a rename. TODO in 5.1: - remove check_db_used - deploy THD::set_db in mysql_change_db See also comments to individual files. mysql-test/r/create.result: Modify the result file: a database can never be NULL. mysql-test/r/ps.result: Update test results (Bug#17199 et al) mysql-test/r/sp.result: Update test results (Bug#17199 et al) mysql-test/t/create.test: Update the id of the returned error. mysql-test/t/ps.test: Add test coverage for prepared statements and current database.

/*
Change the current database if needed.
SYNOPSIS
sp_use_new_db()
thd thread handle
new_db new database name (a string and its length)
old_db [IN] str points to a buffer where to store the old
database, length contains the size of the buffer
[OUT] if old db was not NULL, its name is copied
to the buffer pointed at by str and length is updated
accordingly. Otherwise str[0] is set to '\0' and length
is set to 0. The out parameter should be used only if
the database name has been changed (see dbchangedp).
dbchangedp [OUT] is set to TRUE if the current database is changed,
FALSE otherwise. A database is not changed if the old
name is the same as the new one, both names are empty,
or an error has occurred.
RETURN VALUE
0 success
1 access denied or out of memory (the error message is
set in THD)

A fix and a test case for Bug#19022 "Memory bug when switching db during trigger execution" Bug#17199 "Problem when view calls function from another database." Bug#18444 "Fully qualified stored function names don't work correctly in SELECT statements" Documentation note: this patch introduces a change in behaviour of prepared statements. This patch adds a few new invariants with regard to how THD::db should be used. These invariants should be preserved in future: - one should never refer to THD::db by pointer and always make a deep copy (strmake, strdup) - one should never compare two databases by pointer, but use strncmp or my_strncasecmp - TABLE_LIST object table->db should be always initialized in the parser or by creator of the object. For prepared statements it means that if the current database is changed after a statement is prepared, the database that was current at prepare remains active. This also means that you can not prepare a statement that implicitly refers to the current database if the latter is not set. This is not documented, and therefore needs documentation. This is NOT a change in behavior for almost all SQL statements except: - ALTER TABLE t1 RENAME t2 - OPTIMIZE TABLE t1 - ANALYZE TABLE t1 - TRUNCATE TABLE t1 -- until this patch t1 or t2 could be evaluated at the first execution of prepared statement. CURRENT_DATABASE() still works OK and is evaluated at every execution of prepared statement. Note, that in stored routines this is not an issue as the default database is the database of the stored procedure and "use" statement is prohibited in stored routines. This patch makes obsolete the use of check_db_used (it was never used in the old code too) and all other places that check for table->db and assign it from THD::db if it's NULL, except the parser. How this patch was created: THD::{db,db_length} were replaced with a LEX_STRING, THD::db. All the places that refer to THD::{db,db_length} were manually checked and: - if the place uses thd->db by pointer, it was fixed to make a deep copy - if a place compared two db pointers, it was fixed to compare them by value (via strcmp/my_strcasecmp, whatever was approproate) Then this intermediate patch was used to write a smaller patch that does the same thing but without a rename. TODO in 5.1: - remove check_db_used - deploy THD::set_db in mysql_change_db See also comments to individual files. mysql-test/r/create.result: Modify the result file: a database can never be NULL. mysql-test/r/ps.result: Update test results (Bug#17199 et al) mysql-test/r/sp.result: Update test results (Bug#17199 et al) mysql-test/t/create.test: Update the id of the returned error. mysql-test/t/ps.test: Add test coverage for prepared statements and current database.

A fix and a test case for Bug#19022 "Memory bug when switching db during trigger execution" Bug#17199 "Problem when view calls function from another database." Bug#18444 "Fully qualified stored function names don't work correctly in SELECT statements" Documentation note: this patch introduces a change in behaviour of prepared statements. This patch adds a few new invariants with regard to how THD::db should be used. These invariants should be preserved in future: - one should never refer to THD::db by pointer and always make a deep copy (strmake, strdup) - one should never compare two databases by pointer, but use strncmp or my_strncasecmp - TABLE_LIST object table->db should be always initialized in the parser or by creator of the object. For prepared statements it means that if the current database is changed after a statement is prepared, the database that was current at prepare remains active. This also means that you can not prepare a statement that implicitly refers to the current database if the latter is not set. This is not documented, and therefore needs documentation. This is NOT a change in behavior for almost all SQL statements except: - ALTER TABLE t1 RENAME t2 - OPTIMIZE TABLE t1 - ANALYZE TABLE t1 - TRUNCATE TABLE t1 -- until this patch t1 or t2 could be evaluated at the first execution of prepared statement. CURRENT_DATABASE() still works OK and is evaluated at every execution of prepared statement. Note, that in stored routines this is not an issue as the default database is the database of the stored procedure and "use" statement is prohibited in stored routines. This patch makes obsolete the use of check_db_used (it was never used in the old code too) and all other places that check for table->db and assign it from THD::db if it's NULL, except the parser. How this patch was created: THD::{db,db_length} were replaced with a LEX_STRING, THD::db. All the places that refer to THD::{db,db_length} were manually checked and: - if the place uses thd->db by pointer, it was fixed to make a deep copy - if a place compared two db pointers, it was fixed to compare them by value (via strcmp/my_strcasecmp, whatever was approproate) Then this intermediate patch was used to write a smaller patch that does the same thing but without a rename.

A fix and a test case for Bug#19022 "Memory bug when switching db during trigger execution" Bug#17199 "Problem when view calls function from another database." Bug#18444 "Fully qualified stored function names don't work correctly in SELECT statements" Documentation note: this patch introduces a change in behaviour of prepared statements. This patch adds a few new invariants with regard to how THD::db should be used. These invariants should be preserved in future: - one should never refer to THD::db by pointer and always make a deep copy (strmake, strdup) - one should never compare two databases by pointer, but use strncmp or my_strncasecmp - TABLE_LIST object table->db should be always initialized in the parser or by creator of the object. For prepared statements it means that if the current database is changed after a statement is prepared, the database that was current at prepare remains active. This also means that you can not prepare a statement that implicitly refers to the current database if the latter is not set. This is not documented, and therefore needs documentation. This is NOT a change in behavior for almost all SQL statements except: - ALTER TABLE t1 RENAME t2 - OPTIMIZE TABLE t1 - ANALYZE TABLE t1 - TRUNCATE TABLE t1 -- until this patch t1 or t2 could be evaluated at the first execution of prepared statement. CURRENT_DATABASE() still works OK and is evaluated at every execution of prepared statement. Note, that in stored routines this is not an issue as the default database is the database of the stored procedure and "use" statement is prohibited in stored routines. This patch makes obsolete the use of check_db_used (it was never used in the old code too) and all other places that check for table->db and assign it from THD::db if it's NULL, except the parser. How this patch was created: THD::{db,db_length} were replaced with a LEX_STRING, THD::db. All the places that refer to THD::{db,db_length} were manually checked and: - if the place uses thd->db by pointer, it was fixed to make a deep copy - if a place compared two db pointers, it was fixed to compare them by value (via strcmp/my_strcasecmp, whatever was approproate) Then this intermediate patch was used to write a smaller patch that does the same thing but without a rename. TODO in 5.1: - remove check_db_used - deploy THD::set_db in mysql_change_db See also comments to individual files. mysql-test/r/create.result: Modify the result file: a database can never be NULL. mysql-test/r/ps.result: Update test results (Bug#17199 et al) mysql-test/r/sp.result: Update test results (Bug#17199 et al) mysql-test/t/create.test: Update the id of the returned error. mysql-test/t/ps.test: Add test coverage for prepared statements and current database. In scope of work on Bug#17199 "Problem when view calls function from another database." mysql-test/t/sp.test: Add a test case for Bug#17199 "Problem when view calls function from another database." and Bug#18444 "Fully qualified stored function names don't work correctly in SELECT statements". Test a complementary problem. sql/item_strfunc.cc: Touch the code that reads thd->db (cleanup). sql/log_event.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/slave.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/slave.h: Remove a declaration for a method that is used only in one module. sql/sp.cc: Rewrite sp_use_new_db: this is a cleanup that I needed in order to understand this function and ensure that it has no bugs. sql/sp.h: Add a new declaration for sp_use_new_db (uses LEX_STRINGs) and a comment. sql/sp_head.cc: - drop sp_name_current_db_new - a creator of sp_name class that was used when sp_name was created for an identifier without an explicitly initialized database. Now we pass thd->db to constructor of sp_name right in the parser. - rewrite sp_head::init_strings: name->m_db is always set now - use the new variant of sp_use_new_db - we don't need to update thd->db with SP MEM_ROOT pointer anymore when parsing a stored procedure, as noone will refer to it (yes!) sql/sp_head.h: - remove unneded methods and members sql/sql_class.h: - introduce 3 THD methods to work with THD::db: .set_db to assign the current database .reset_db to reset the current database (temporarily) or set it to NULL .opt_copy_db_to - to deep-copy thd->db to a pointer if it's not NULL sql/sql_db.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/sql_insert.cc: - replace checks with asserts: table_list->db must be always set in the parser. sql/sql_lex.h: - add a comment sql/sql_parse.cc: - implement the invariant described in the changeset comment. - remove juggling with lex->sphead in SQLCOM_CREATE_PROCEDURE: now db_load_routine uses its own LEX object and doesn't damage the main LEX. - add DBUG_ASSERT(0) to unused "check_db_used" sql/sql_table.cc: - replace a check with an assert (table_ident->db) sql/sql_trigger.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/sql_udf.cc: - use thd->set_db instead of direct modification of to thd->db sql/sql_view.cc: - replace a check with an assert (view->db) sql/sql_yacc.yy: - make sure that we always copy table->db or name->db or ident->db or select_lex->db from thd->db if the former is not set. If thd->db is not set but is accessed, return an error. sql/tztime.cc: - be nice, never copy thd->db by pointer.
