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 ...

Clumsy but working fix for bug #11973 "SELECT .. INTO var_name; in trigger
cause crash on update". Let us update "thd" pointer in LEX, all its units and in LEX::result before executing statement in trigger body, since triggers are associated with TABLE object and because of this can be used in different threads. mysql-test/r/trigger.result: Added test case for bug #11973 "SELECT .. INTO var_name; in trigger cause crash on update". mysql-test/t/trigger.test: Added test case for bug #11973 "SELECT .. INTO var_name; in trigger cause crash on update". sql/item_subselect.cc: subselect_engine: Moved implementation of set_thd() method to item_subselect.cc, since now it also sets "thd" for subselect_engine::result. sql/item_subselect.h: subselect_engine: Moved implementation of set_thd() method to item_subselect.cc, since now it also sets "thd" for subselect_engine::result. sql/sql_class.h: select_result: Added set_thd() method for updating select_result::thd value (we need this in cases when statement to which this select_result belongs will be used in different threads, as it happens for statements in trigger body). multi_delete/multi_update: Got rid of redundant "thd" member (we already have it in select_result). sql/sql_delete.cc: multi_delete: Got rid of redundant "thd" member (we already have it in select_result). sql/sql_lex.h: st_select_lex_unit: Added set_thd() method for updating st_select_lex_unit::thd value (we need this in cases when statement to which this unit belongs will be used in different threads, as it happens for statements in trigger body). We don't update thd of select_result pointed by st_select_lex_unit::result in this method, since it is either have too short lifetime (i.e. created for each execution) or is accessible via Item_subquery or LEX::result and thus already taken care of. sql/sql_parse.cc: multi_delete: Got rid of redundant "thd" member (we already have it in select_result). sql/sql_prepare.cc: reinit_stmt_before_use(): We have to update "thd" pointer in LEX, all its units and in LEX::result, since statements which belong to trigger body are associated with TABLE object and because of this can be used in different threads. sql/sql_update.cc: multi_update: Got rid of redundant "thd" member (we already have it in select_result). |

Fix for bugs #5892/6182/8751/8758/10994 (based on Antony's patch)
"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. |

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). |

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. |

- don't call JOIN::join_free(1) twice for every join in JOIN::cleanup().
The reason it happened was that both, JOIN::cleanup() and JOIN::join_free(), went over all nested joins and called cleanup/join_free for them. For that: - split recursive and non-recursive parts of JOIN::cleanup() and JOIN::join_free() - rename JOIN::cleanup to JOIN::destroy, as it actually destroys its argument - move the recursive part of JOIN::cleanup to st_select_lex::cleanup - move the non-recursive part of JOIN::join_free to the introduced method JOIN::cleanup(). sql/sql_lex.h: Add st_select_lex::cleanup, a counterpart of st_select_lex_unit::cleanup() sql/sql_select.cc: - remove two unused arguments from return_zero_rows - split JOIN::join_free and JOIN::cleanup to recursive and non-recursive parts. - note, the assert in JOIN::join_free _does_ fail in having.test. We have two options: a) propagate `full' flag to the nested joins. We did it before, and this patch didn't change it. If so, we can end up cleaning up an uncacheable JOIN (that is, the join that we might need again). b) evaluate own 'full' flag on every level. In this case, we might end up with tables freed in mysql_unlock_read_tables, but not cleaned up properly, and this may be even worse. The test suite passes with both approaches, but not with the assert. sql/sql_select.h: - declarations for JOIN::cleanup() and JOIN::join_free() sql/sql_union.cc: Add st_select_lex::cleanup, a counterpart of st_select_lex_unit::cleanup(): move the recursive part of JOIN::cleanup to it. |

A preparatory patch to help adding JOIN::transform() and move one-time
query transformations to the PREPARE stage (prepared statements). sql/item.h: Remove an unused friend declaration. sql/mysql_priv.h: Change signature of insert_fields() sql/sp_head.cc: Make is_stmt_prepare_or_first_sp_execute really work: reset SP state to EXECUTED after execution. sql/sql_base.cc: allocate_view_names flag of insert_fields is removed. The purpose of this variable was to amend the case when a view is replaced with a base table between subsequent executions of a prepared statement: in that case the new table theoretically can be used instead of the view. If allocate_view_names was set, all the references to the view expressions were replaced with Item_field's which in turn could have been resolved by their names. But this approach doesn't work for other reasons, so let's not try to help what must be solved by TDC. sql/sql_class.h: Add is_first_sp_execute() helper method. sql/sql_handler.cc: insert_fields signature changed. sql/sql_lex.h: Add a comment for variable 'first_execution'. |

Fix for bug #11158 "Can't perform multi-delete in stored procedure".
In order to make multi-delete SP friendly we need to have all table locks for the elements of main statement table list properly set at the end of parsing. Also performed small cleanup: We don't need relink_tables_for_multidelete() any longer since the only case now when TABLE_LIST::correspondent_table is non-zero are tables in auxilary table list of multi-delete and these tables are handled specially in mysql_multi_delete_prepare(). mysql-test/r/sp-threads.result: Added test case for bug #11158 "Can't perform multi-delete in stored procedure". mysql-test/t/sp-threads.test: Added test case for bug #11158 "Can't perform multi-delete in stored procedure". sql/mysql_priv.h: - Removed third argument from the declaration of multi_delete_precheck() as nowdays we calculate number of tables in multi-delete from which we are going to delete rows right at the end of statement parsing. - Introduced definition of multi_delete_set_locks_and_link_aux_tables() which is responsible for propagation of proper table locks from multi-delete's auxilary table list to the main list and binding corresponding tables in these two lists. sql/sql_base.cc: Removed relink_tables_for_multidelete() routine and its invocations. We don't need them in 5.0 since the only case now when TABLE_LIST::correspondent_table is non-zero are tables in auxilary table list of multi-delete and these tables are handled specially in mysql_multi_delete_prepare(). sql/sql_lex.h: LEX::table_count Added description of new role of this LEX member for multi-delete. Now for this statement we store number of tables from which we should delete records there. sql/sql_parse.cc: multi_delete_precheck(): Moved code which is responsible for iterating through auxilary table list and binding its elements with corresponding elements of main table list, and properly updating locks in it to separate function - multi_delete_set_locks_and_link_aux_tables(). This is because in order to make multi-delete SP friendly we need to have all locks set properly at the end of statement parsing. So we are introducing new function which will be called from parser. We also calculate number of tables from which we are going to perform deletions there and store this number for later usage in LEX::table_count. Also removed some no longer needed code. sql/sql_prepare.cc: mysql_test_multidelete(): Now multi_delete_precheck() takes only two arguments, so we don't need to pass fake third parameter. sql/sql_yacc.yy: delete: In order to make multi-delete SP friendly we need to have all table locks for the elements of main statement table list properly set at the end of parsing. |

error for LIMIT placeholder". The patch adds grammar support for LIMIT ?, ? and changes the type of ST_SELECT_LEX::select_limit,offset_limit from ha_rows to Item*, so that it can point to Item_param. mysql-test/include/ps_modify.inc: Fix existing tests: now LIMIT can contain placeholders. mysql-test/include/ps_query.inc: Fix existing tests: now LIMIT can contain placeholders. mysql-test/r/ps.result: Add basic test coverage for LIMIT ?, ? and fix test results. mysql-test/r/ps_2myisam.result: Fix test results: now LIMIT can contain placeholders. mysql-test/r/ps_3innodb.result: Fix test results: now LIMIT can contain placeholders. mysql-test/r/ps_4heap.result: Fix test results: now LIMIT can contain placeholders. mysql-test/r/ps_5merge.result: Fix test results: now LIMIT can contain placeholders. mysql-test/r/ps_6bdb.result: Fix test results: now LIMIT can contain placeholders. mysql-test/r/ps_7ndb.result: Fix test results: now LIMIT can contain placeholders. mysql-test/t/ps.test: Add basic test coverage for LIMIT ?, ?. sql/item.h: Add a short-cut for (ulonglong) val_int() to Item. Add a constructor to Item_int() that accepts ulonglong. Simplify Item_uint constructor by using the c-tor above. sql/item_subselect.cc: Now select_limit has type Item *. We can safely create an Item in Item_exists_subselect::fix_length_and_dec(): it will be allocated in runtime memory root and freed in the end of execution. sql/sp_head.cc: Add a special initalization state for stored procedures to be able to easily distinguish the first execution of a stored procedure from prepared statement prepare. sql/sql_class.h: Introduce new state 'INITIALIZED_FOR_SP' to be able to easily distinguish the first execution of a stored procedure from prepared statement prepare. sql/sql_derived.cc: - use unit->set_limit() to set unit->select_limit_cnt, offset_limit_cnt evreryplace. Add a warning about use of set_limit in mysql_derived_filling. sql/sql_error.cc: - use unit->set_limit() to set unit->select_limit_cnt, offset_limit_cnt evreryplace. - this change is also aware of bug#11095 "show warnings limit 0 returns all rows instead of zero rows", so the one who merges the bugfix from 4.1 can use local version of sql_error.cc. sql/sql_handler.cc: - use unit->set_limit() to initalize unit->select_limit_cnt,offset_limit_cnt everyplace. sql/sql_lex.cc: Now ST_SELECT_LEX::select_limit, offset_limit have type Item * sql/sql_lex.h: Now ST_SELECT_LEX::select_limit, offset_limit have type Item * sql/sql_parse.cc: - use unit->set_limit() to initalize unit->select_limit_cnt,offset_limit_cnt everyplace. - we can create an Item_int to set global limit of a statement: it will be created in the runtime mem root and freed in the end of execution. sql/sql_repl.cc: Use unit->set_limit to initialize limits. sql/sql_select.cc: - select_limit is now Item* so the proper way to check for default value is to compare it with NULL. sql/sql_union.cc: Evaluate offset_limit_cnt using the new type of ST_SELECT_LEX::offset_limit sql/sql_view.cc: Now ST_SELECT_LEX::select_limit, offset_limit have type Item * sql/sql_yacc.yy: Add grammar support for LIMIT ?, ? clause. |

Preparatory (and the most problematic) patch for Bug#7306
"the server side preparedStatement error for LIMIT placeholder", which moves all uses of LIMIT clause from PREPARE to OPTIMIZE and later steps. After-review fixes. mysql-test/r/group_min_max.result: Test results fixed for EXPLAINs when using GROUP_MIN_MAX access plan. sql/item_subselect.cc: Move setting of the internal LIMIT used for IN/ALL/ANY/EXISTS subqueries to one place: Item_exists_subselect::fix_length_and_dec(). This implies that unit->select_limit_cnt is not set until the item is fixed. This is OK, as now LIMIT values are not used until JOIN::optimize. sql/mysql_priv.h: setup_tables no longer needs a special flag for the case when it's called from JOIN::reinit() (we don't need to call setup_tables between two executions of a correlated subquery). sql/opt_range.cc: Fix a glitch in GROUP_MIN_MAX access plan: we should use table metadata, not field data, to evaluate max_used_key_length, which is then used for explain. sql/sp.cc: - setup_tables signature changed. sql/sql_base.cc: - setup_tables no longer needs a special mode for subqueries. Unused checks were removed. sql/sql_delete.cc: - setup_tables signature changed sql/sql_help.cc: - setup_tables signature changed sql/sql_insert.cc: - setup_tables signature changed sql/sql_lex.cc: Consolidate setting of internal LIMIT for IN/ALL/ANY/EXISTS subqeries in one place, and hence remove it from st_select_lex::test_limit(). sql/sql_lex.h: Cleanup signature of st_select_lex_unit::init_prepare_fake_select_lex(). sql/sql_load.cc: - setup_tables signature changed sql/sql_olap.cc: - setup_tables signature changed sql/sql_parse.cc: - st_select_lex_unit::set_limit() signature changed sql/sql_select.cc: Move setting of JOIN::select_limit from JOIN::prepare to JOIN::optimize. At prepare, limit is unknown yet. Remove excessive cleanups from JOIN::reinit which were overwriting join->join_tab[i]->table->used_keys. This fixes the bug which was triggered by the change in item_subselect.cc. sql/sql_union.cc: Class st_select_lex_unit was changed to avoid calls to st_select_lex_unit::set_limit from places where it may be unknown. Now unit->select_limit_cnt is set at ::exec(). st_select_lex_unit::init_prepare_fake_select_lex(): - move out set_limit functionality - remove a few lines of dead code. st_select_lex_unit::prepare(): - now we don't call set_limit at the time of prepare, so the value of unit->select_limit_cnt may be unknown here. Use sl->select_limit instead. st_select_lex_unit::exec(): - cleanup - call set_limit explicitly as it has been moved out of init_prepare_fake_select_lex. sql/sql_update.cc: - setup_tables signature changed |

New more SP-locking friendly approach to handling locks in multi-update. Now we mark all tables of multi-update as needing write lock at parsing stage and if possible downgrade lock at execution stage (For its work SP-locking mechanism needs to know all lock types right after parsing stage). mysql-test/r/sp-threads.result: Added test for bug #9486 "Can't perform multi-update in stored procedure". mysql-test/t/sp-threads.test: Added test for bug #9486 "Can't perform multi-update in stored procedure". sql/sp_head.cc: SP_TABLE, sp_head::merge_table_list()/add_used_tables_to_table_list(): Since some queries during their execution (e.g. multi-update) may change type of lock for some of their tables and thus change lock_type member for some of elements of table list, we should store type of lock in SP_TABLE struct explicitly instead of using lock_type member of TABLE_LIST object pointed by SP_TABLE::table. sql/sql_lex.h: Removed no longer used LEX::multi_lock_option member. sql/sql_prepare.cc: mysql_test_update(): We don't need to bother about LEX::multi_lock_option if we convert multi-update to update anymore.

WL#874 "Extended LOAD DATA".
Now one can use user variables as target for data loaded from file (besides table's columns). Also LOAD DATA got new SET-clause in which one can specify values for table columns as expressions. For example the following is possible: LOAD DATA INFILE 'words.dat' INTO TABLE t1 (a, @b) SET c = @b + 1; This patch also implements new way of replicating LOAD DATA. Now we do it similarly to other queries. We store LOAD DATA query in new Execute_load_query event (which is last in the sequence of events representing LOAD DATA). When we are executing this event we simply rewrite part of query which holds name of file (we use name of temporary file) and then execute it as usual query. In the beggining of this sequence we use Begin_load_query event which is almost identical to Append_file event client/mysqlbinlog.cc: Added support of two new binary log events Begin_load_query_log_event and Execute_load_query_log_Event which are used to replicate LOAD DATA INFILE. mysql-test/r/ctype_ucs.result: Addition of two new types of binary log events shifted binlog positions.

Moved code from Item_func_set_user_var::update_hash() function to separate static function to be able to reuse it in this new class. sql/item_func.h: Added Item_user_var_as_out_param class that represents user variable which used as out parameter in LOAD DATA. sql/log_event.cc: New way of replicating LOAD DATA. Now we do it similarly to other queries. We store LOAD DATA query in new Execute_load_query event (which is last in the sequence of events representing LOAD DATA). When we are executing this event we simply rewrite part of query which holds name of file (we use name of temporary file) and then execute it as usual query. In the beggining of this sequence we use Begin_load_query event which is almost identical to Append_file event. sql/log_event.h: New way of replicating LOAD DATA. Now we do it similarly to other queries. We store LOAD DATA query in new Execute_load_query event (which is last in the sequence of events representing LOAD DATA). When we are executing this event we simply rewrite part of query which holds name of file (we use name of temporary file) and then execute it as usual query. In the beggining of this sequence we use Begin_load_query event which is almost identical to Append_file event. sql/mysql_priv.h: Now mysql_load() has two more arguments. They are needed to pass list of columns and corresponding expressions from new LOAD DATA's SET clause. sql/share/errmsg.txt: Added new error message which is used to forbid loading of data from fixed length rows to variables. sql/sql_lex.h: Added LEX::fname_start/fname_end members. They are pointers to part of LOAD DATA statement which should be rewritten during replication (file name + little extra). sql/sql_load.cc: Added support for extended LOAD DATA. Now one can use user variables as target for data loaded from file (besides table's columns). Also LOAD DATA got new SET-clause in which one can specify values for table columns as expressions. Updated mysql_load()/read_fixed_length()/read_sep_field() to support this functionality (now they can read data from file to both columns and variables and assign do calculations and assignments specified in SET clause). We also use new approach for LOAD DATA binlogging/replication. sql/sql_parse.cc: mysql_execute_command(): Since now we have SET clause in LOAD DATA we should also check permissions for tables used in its expressions. Also mysql_load() has two more arguments to pass information about this clause. sql/sql_repl.cc: New way of replicating LOAD DATA. Now we do it similarly to other queries. We store LOAD DATA query in new Execute_load_query event (which is last in the sequence of events representing LOAD DATA). When we are executing this event we simply rewrite part of query which holds name of file (we use name of temporary file) and then execute it as usual query. In the beggining of this sequence we use Begin_load_query event which is almost identical to Append_file event. sql/sql_repl.h: struct st_load_file_info: Removed memebers which are no longer needed for LOAD DATA binnlogging. sql/sql_yacc.yy: Added support for extended LOAD DATA syntax. Now one can use user variables as target for data loaded from file (besides table's columns). Also LOAD DATA got new SET-clause in which one can specify values for table columns as expressions. For example the following is possible: LOAD DATA INFILE 'words.dat' INTO TABLE t1 (a, @b) SET c = @b + 1; Also now we save pointers to the beginning and to the end of part of LOAD DATA statement which should be rewritten during replication. |

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. |

Fixed wrong memory references found by purify
(No really critical errors found, but a few possible wrong results) innobase/dict/dict0dict.c: Replace memcmp with comparison of characters to avoid warnings from purify when 'sptr' points to a very short string mysql-test/r/select_found.result: Add missing drop table mysql-test/r/type_set.result: More tests mysql-test/t/select_found.test: Add missing drop table mysql-test/t/type_set.test: More tests mysys/my_init.c: Avoid warning from purify (purify doesn't handle getrusage() properly) sql/field.h: enum & set are sorted as numbers. This fixes an access to uninitialized memory when enum/set are multi-byte characters sql/filesort.cc: enum & set are sorted as numbers. This fixes an access to uninitialized memory when enum/set are multi-byte characters sql/item_cmpfunc.cc: Fixed warning from purify.

Fix signatures of placement operator delete in places where placement
delete is declared. As we don't use exceptions placement delete is never called and the fix only affects numerous warnings when compiling with MS Visual C++. For more info see http://www.gotw.ca/gotw/010.htm. sql/item.h: Fix the signature of placement operator delete for class Item. sql/sql_class.cc: Add placement delete operator to suppress a warning under Windows. sql/sql_lex.h: Fix the signature of placement operator delete for class LEX sql/sql_list.h: Fix the signature of placement operator delete for class Sql_alloc sql/sql_string.h: Fix the signature of placement operator delete for class Sql_string |
