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

"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, 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.

Now we use more general ER_SP_BADSTATEMENT in this case. Instead added error message for barking about statements which should not be allowed inside of stored functions or triggers. It is safe to do this since it is highly unprobable that someone will upgrade first to the new 5.0 release and then downgrade back to the old one. sql/sql_parse.cc: reload_acl_and_cache(): FLUSH TABLES and FLUSH PRIVILEGES should not be allowed if we are inside of stored function or trigger. sql/sql_yacc.yy: We should not allow FLUSH statement inside both triggers and stored functions. Replaced error which is thrown in this case with more specific. Also now we issue more general ER_SP_BADSTATEMENT error when one tries to use USE command inside of stored routine.

"Triggers have the wrong namespace" "Triggers: duplicate names allowed" "Triggers: CREATE TRIGGER does not accept fully qualified names" "SHOW TRIGGERS" mysql-test/r/information_schema.result: Added tests for new INFORMATION_SCHEMA.TRIGGERS view and SHOW TRIGGERS command. mysql-test/r/information_schema_db.result: INFORMATION_SCHEMA.TRIGGERS view was added. mysql-test/r/rpl_sp.result: Now DROP TRIGGER interprets first part of trigger identifier as database name and not as table name. Adjusted tests properly. mysql-test/r/trigger.result: Now DROP TRIGGER interprets first part of trigger identifier as database name and not as table name. Adjusted tests properly. Added test checking that triggers have database wide namespace. Added test for bug #8791 "Triggers: Allowed to create triggers on a subject table in a different DB". mysql-test/r/view.result: Now DROP TRIGGER interprets first part of trigger identifier as database name and not as table name. Adjusted tests properly. mysql-test/t/information_schema.test: Added tests for new INFORMATION_SCHEMA.TRIGGERS view and SHOW TRIGGERS command. mysql-test/t/rpl_sp.test: Now DROP TRIGGER interprets first part of trigger identifier as database name and not as table name. Adjusted tests properly. mysql-test/t/trigger.test: Now DROP TRIGGER interprets first part of trigger identifier as database name and not as table name. Adjusted tests properly. Added test checking that triggers have database wide namespace. Added test for bug #8791 "Triggers: Allowed to create triggers on a subject table in a different DB". mysql-test/t/view.test: Now DROP TRIGGER interprets first part of trigger identifier as database name and not as table name. Adjusted tests properly. sql/handler.cc: Added .TRN tho the list of known file extensions assoicated with tables. sql/item.h: trg_action_time_type/trg_event_type enums: Added TRG_ACTION_MAX/TRG_EVENT_MAX elements which should be used instead of magical values in various loops where we iterate through all types of trigger action times or/and trigger event types. sql/lex.h: Added new symbol "TRIGGERS". sql/mysql_priv.h: Added declaration of constant holding extension for trigger name (.TRN) files. sql/mysqld.cc: Added statistical variable for SHOW TRIGGERS command. sql/share/errmsg.txt: Added error message saying that one attempts to create trigger in wrong schema. sql/sp.cc: Replaced magical values with TRG_EVENT_MAX/TRG_ACTION_MAX constants. sql/sql_base.cc: open_unireg_entry(): Now Table_triggers_list::check_n_load() has one more argument which controls whether we should prepare Table_triggers_list with fully functional triggers or load only their names. sql/sql_lex.h: Added element for new SHOW TRIGGERS command to enum_sql_command enum. sql/sql_parse.cc: prepare_schema_table(): Added support for SHOW TRIGGERS statement. sql/sql_show.cc: Added new INFORMATION_SCHEMA.TRIGGERS view and SHOW TRIGGERS command. sql/sql_table.cc: mysql_rm_table_part2(): Replaced simple deletion of .TRG file with call to Table_triggers_list::drop_all_triggers which will also delete .TRN files for all triggers associated with table. sql/sql_trigger.cc: Now triggers have database wide namespace. 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. Moreover DROP TRIGGER treats first part of trigger identifier as database name now. Updated mysql_create_or_drop_trigger() routine and Table_triggers_list::create_trigger()/drop_trigger()/check_n_load() methods accordingly. Added add_table_for_trigger() routine and Table_triggers_list::drop_all_triggers() method. Added Table_triggers_list::get_trigger_info() for obtaining trigger metadata. sql/sql_trigger.h: Table_triggers_list: Use TRG_EVENT_MAX, TRG_ACTION_MAX instead of magic values. Added get_trigger_info() method for obtaining trigger's meta-data. Added drop_all_triggers() method which drops all triggers for table. Added declarations of trg_action_time_type_names/trg_event_type_names arrays which hold names of triggers action time types and event types. sql/sql_yacc.yy: Changed grammar for CREATE/DROP TRIGGER to support database wide trigger namespace. Added new SHOW TRIGGERS statement. sql/table.h: enum enum_schema_tables: Added constant for new INFORMATION_SCHEMA.TRIGGERS view.

data": remove the fix for another bug (8807) that added OUTER_REF_TABLE_BIT to all subqueries that used a placeholder to prevent their evaluation at prepare. As this bit hanged in Item_subselect::used_tables_cache for ever, a constant subquery with a placeholder was never evaluated as such, which caused wrong choice of the execution plan for the statement. - to fix Bug#8807 backport a better fix from 5.0 - post-review fixes. mysql-test/r/ps.result: Bug#11458: test results fixed mysql-test/t/ps.test: - add a test case for Bug#11458 "Prepared statement with subselects return random data" sql/item.cc: - remove unnecessary Item_param::fix_fields - fix Item_param::set_null to set item_type accordingly (safety: Item_param should behave like a basic constant). sql/item.h: Remove Item_param::fix_fields sql/item_subselect.h: Remove no more existing friend. sql/mysql_priv.h: Add UNCACHEABLE_PREPARE to mark all subqueries as uncacheable if in statement prepare (backport from 5.0). sql/sql_lex.h: Comment fixed. sql/sql_parse.cc: If in statement prepare, mark all subqueries as uncacheable (backport from 5.0) sql/sql_prepare.cc: Switch off the uncacheable flag from all subqueries after statement prepare is done (backport from 5.0)

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.
