unknown	9dc3088f9e	A fix and a test case for Bug#26141 mixing table types in trigger causes full table lock on innodb table. Also fixes Bug#28502 Triggers that update another innodb table will block on X lock unnecessarily (duplciate). Code review fixes. Both bugs' synopses are misleading: InnoDB table is not X locked. The statements, however, cannot proceed concurrently, but this happens due to lock conflicts for tables used in triggers, not for the InnoDB table. If a user had an InnoDB table, and two triggers, AFTER UPDATE and AFTER INSERT, competing for different resources (e.g. two distinct MyISAM tables), then these two triggers would not be able to execute concurrently. Moreover, INSERTS/UPDATES of the InnoDB table would not be able to run concurrently. The problem had other side-effects (see respective bug reports). This behavior was a consequence of a shortcoming of the pre-locking algorithm, which would not distinguish between different DML operations (e.g. INSERT and DELETE) and pre-lock all the tables that are used by any trigger defined on the subject table. The idea of the fix is to extend the pre-locking algorithm to keep track, for each table, what DML operation it is used for and not load triggers that are known to never be fired. mysql-test/r/trigger-trans.result: Update results (Bug#26141) mysql-test/r/trigger.result: Update results (Bug#28502) mysql-test/t/trigger-trans.test: Add a test case for Bug#26141 mixing table types in trigger causes full table lock on innodb table. mysql-test/t/trigger.test: Add a test case for Bug#28502 Triggers that update another innodb table will block echo on X lock unnecessarily. Add more test coverage for triggers. sql/item.h: enum trg_event_type is needed in table.h sql/sp.cc: Take into account table_list->trg_event_map when determining what tables to pre-lock. After this change, if we attempt to fire a trigger for which we had not pre-locked any tables, error 'Table was not locked with LOCK TABLES' will be printed. This, however, should never happen, provided the pre-locking algorithm has no programming bugs. Previously a trigger key in the sroutines hash was based on the name of the table the trigger belongs to. This was possible because we would always add to the pre-locking list all the triggers defined for a table when handling this table. Now the key is based on the name of the trigger, owing to the fact that a trigger name must be unique in the database it belongs to. sql/sp_head.cc: Generate sroutines hash key in init_spname(). This is a convenient place since there we have all the necessary information and can avoid an extra alloc. Maintain and merge trg_event_map when adding and merging elements of the pre-locking list. sql/sp_head.h: Add ,m_sroutines_key member, used when inserting the sphead for a trigger into the cache of routines used by a statement. Previously the key was based on the table name the trigger belonged to, since for a given table we would add to the sroutines list all the triggers defined on it. sql/sql_lex.cc: Introduce a new lex step: set_trg_event_type_for_tables(). It is called when we have finished parsing but before opening and locking tables. Now this step is used to evaluate for each TABLE_LIST instance which INSERT/UPDATE/DELETE operation, if any, it is used in. In future this method could be extended to aggregate other information that is hard to aggregate during parsing. sql/sql_lex.h: Add declaration for set_trg_event_type_for_tables(). sql/sql_parse.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). Remove tabs. sql/sql_prepare.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). sql/sql_trigger.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). sql/sql_trigger.h: Remove an obsolete member. sql/sql_view.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). sql/sql_yacc.yy: Move assignment of sp_head::m_type before calling sp_head::init_spname(), one is now used inside another. sql/table.cc: Implement TABLE_LIST::set_trg_event_map() - a method that calculates wh triggers may be fired on this table when executing a statement. sql/table.h: Add missing declarations. Move declaration of trg_event_type from item.h (it will be needed for trg_event_map bitmap when we start using Bitmap template instead of uint8).	19 years ago
unknown	405f82d390	Patch for the following bugs: - BUG#11986: Stored routines and triggers can fail if the code has a non-ascii symbol - BUG#16291: mysqldump corrupts string-constants with non-ascii-chars - BUG#19443: INFORMATION_SCHEMA does not support charsets properly - BUG#21249: Character set of SP-var can be ignored - BUG#25212: Character set of string constant is ignored (stored routines) - BUG#25221: Character set of string constant is ignored (triggers) There were a few general problems that caused these bugs: 1. Character set information of the original (definition) query for views, triggers, stored routines and events was lost. 2. mysqldump output query in client character set, which can be inappropriate to encode definition-query. 3. INFORMATION_SCHEMA used strings with mixed encodings to display object definition; 1. No query-definition-character set. In order to compile query into execution code, some extra data (such as environment variables or the database character set) is used. The problem here was that this context was not preserved. So, on the next load it can differ from the original one, thus the result will be different. The context contains the following data: - client character set; - connection collation (character set and collation); - collation of the owner database; The fix is to store this context and use it each time we parse (compile) and execute the object (stored routine, trigger, ...). 2. Wrong mysqldump-output. The original query can contain several encodings (by means of character set introducers). The problem here was that we tried to convert original query to the mysqldump-client character set. Moreover, we stored queries in different character sets for different objects (views, for one, used UTF8, triggers used original character set). The solution is - to store definition queries in the original character set; - to change SHOW CREATE statement to output definition query in the binary character set (i.e. without any conversion); - introduce SHOW CREATE TRIGGER statement; - to dump special statements to switch the context to the original one before dumping and restore it afterwards. Note, in order to preserve the database collation at the creation time, additional ALTER DATABASE might be used (to temporary switch the database collation back to the original value). In this case, ALTER DATABASE privilege will be required. This is a backward-incompatible change. 3. INFORMATION_SCHEMA showed non-UTF8 strings The fix is to generate UTF8-query during the parsing, store it in the object and show it in the INFORMATION_SCHEMA. Basically, the idea is to create a copy of the original query convert it to UTF8. Character set introducers are removed and all text literals are converted to UTF8. This UTF8 query is intended to provide user-readable output. It must not be used to recreate the object. Specialized SHOW CREATE statements should be used for this. The reason for this limitation is the following: the original query can contain symbols from several character sets (by means of character set introducers). Example: - original query: CREATE VIEW v1 AS SELECT _cp1251 'Hello' AS c1; - UTF8 query (for INFORMATION_SCHEMA): CREATE VIEW v1 AS SELECT 'Hello' AS c1; client/mysqldump.c: Set original character set and collation before dumping definition query. include/my_sys.h: Move out-parameter to the end of list. mysql-test/lib/mtr_report.pl: Ignore server-warnings during the test case. mysql-test/r/create.result: Update result file. mysql-test/r/ctype_cp932_binlog_stm.result: Update result file. mysql-test/r/events.result: Update result file. mysql-test/r/events_bugs.result: Update result file. mysql-test/r/events_grant.result: Update result file. mysql-test/r/func_in.result: Update result file. mysql-test/r/gis.result: Update result file. mysql-test/r/grant.result: Update result file. mysql-test/r/information_schema.result: Update result file. mysql-test/r/information_schema_db.result: Update result file. mysql-test/r/lowercase_view.result: Update result file. mysql-test/r/mysqldump.result: Update result file. mysql-test/r/ndb_sp.result: Update result file. mysql-test/r/ps.result: Update result file. mysql-test/r/rpl_replicate_do.result: Update result file. mysql-test/r/rpl_sp.result: Update result file. mysql-test/r/rpl_trigger.result: Update result file. mysql-test/r/rpl_view.result: Update result file. mysql-test/r/show_check.result: Update result file. mysql-test/r/skip_grants.result: Update result file. mysql-test/r/sp-destruct.result: Update result file. mysql-test/r/sp-error.result: Update result file. mysql-test/r/sp-security.result: Update result file. mysql-test/r/sp.result: Update result file. mysql-test/r/sql_mode.result: Update result file. mysql-test/r/system_mysql_db.result: Update result file. mysql-test/r/temp_table.result: Update result file. mysql-test/r/trigger-compat.result: Update result file. mysql-test/r/trigger-grant.result: Update result file. mysql-test/r/trigger.result: Update result file. mysql-test/r/view.result: Update result file. mysql-test/r/view_grant.result: Update result file. mysql-test/t/events.test: Update test case (new columns added). mysql-test/t/information_schema.test: Update test case (new columns added). mysql-test/t/show_check.test: Test case for SHOW CREATE TRIGGER in prepared statements and stored routines. mysql-test/t/sp-destruct.test: Update test case (new columns added). mysql-test/t/sp.test: Update test case (new columns added). mysql-test/t/view.test: Update test. mysys/charset.c: Move out-parameter to the end of list. scripts/mysql_system_tables.sql: Add new columns to mysql.proc and mysql.event. scripts/mysql_system_tables_fix.sql: Add new columns to mysql.proc and mysql.event. sql/event_data_objects.cc: Support new attributes for events. sql/event_data_objects.h: Support new attributes for events. sql/event_db_repository.cc: Support new attributes for events. sql/event_db_repository.h: Support new attributes for events. sql/events.cc: Add new columns to SHOW CREATE event resultset. sql/mysql_priv.h: 1.

unknown	2efc0f51cf	Bug #26242 UPDATE with subquery and triggers failing with cluster tables In certain cases AFTER UPDATE/DELETE triggers on NDB tables that referenced subject table didn't see the results of operation which caused invocation of those triggers. In other words AFTER trigger invoked as result of update (or deletion) of particular row saw version of this row before update (or deletion). The problem occured because NDB handler in those cases postponed actual update/delete operations to be able to perform them later as one batch. This fix solves the problem by disabling this optimization for particular operation if subject table has AFTER trigger for this operation defined. To achieve this we introduce two new flags for handler::extra() method: HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH. These are called if there exists AFTER DELETE/UPDATE triggers during a statement that potentially can generate calls to delete_row()/update_row(). This includes multi_delete/multi_update statements as well as insert statements that do delete/update as part of an ON DUPLICATE statement. include/my_base.h: Added HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler when batching of delete/update is not possible. mysql-test/r/ndb_trigger.result: Bug #26242 UPDATE with subquery and triggers failing with cluster tables --- Added new test cases mysql-test/t/ndb_trigger.test: Bug #26242 UPDATE with subquery and triggers failing with cluster tables --- Added new test cases sql/ha_ndbcluster.cc: Bug #26242 UPDATE with subquery and triggers failing with cluster tables: Use HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler when batching of delete/update is not possible sql/ha_ndbcluster.h: Bug #26242 UPDATE with subquery and triggers failing with cluster tables: Added member variables for handling of HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler when batching of delete/update is not possible sql/mysql_priv.h: Added new method prepare_triggers_for_insert_stmt to check if batching of delete/update must be disallowed. sql/sql_delete.cc: Use HA_EXTRA_DELETE_CANNOT_BATCH to inform handler when batching of delete is not possible sql/sql_insert.cc: Added method prepare_triggers_for_insert_stmt to check if batching of delete/update must be dissallowed.

unknown	0e4dd85d67	Fix for bug#20670 "UPDATE using key and invoking trigger that modifies this key does not stop" (version for 5.0 only). UPDATE statement which WHERE clause used key and which invoked trigger that modified field in this key worked indefinetely. This problem occured because in cases when UPDATE statement was executed in update-on-the-fly mode (in which row is updated right during evaluation of select for WHERE clause) the new version of the row became visible to select representing WHERE clause and was updated again and again. We already solve this problem for UPDATE statements which does not invoke triggers by detecting the fact that we are going to update field in key used for scanning and performing update in two steps, during the first step we gather information about the rows to be updated and then doing actual updates. We also do this for MULTI-UPDATE and in its case we even detect situation when such fields are updated in triggers (actually we simply assume that we always update fields used in key if we have before update trigger). The fix simply extends this check which is done in check_if_key_used()/ QUICK_SELECT_I::check_if_keys_used() routine/method in such way that it also detects cases when field used in key is updated in trigger. As nice side-effect we have more precise and thus more optimal perfomance-wise check for the MULTI-UPDATE. Also check_if_key_used()/QUICK_SELECT_I::check_if_keys_used() were renamed to is_key_used()/QUICK_SELECT_I::is_keys_used() in order to better reflect that boolean predicate. Note that this check is implemented in much more elegant way in 5.1 mysql-test/r/trigger.result: Added test case for bug#20670 "UPDATE using key and invoking trigger that modifies this key does not stop". mysql-test/t/trigger.test: Added test case for bug#20670 "UPDATE using key and invoking trigger that modifies this key does not stop". sql/key.cc: Renamed check_if_key_used() to is_key_used(). Also this routine checks if key uses field which can be updated by before update trigger defined on the table. As result we avoid using update-on-the-fly method in cases when trigger updates part of key which is used by select which filters rows to be updated and thus avoid infinite updates. By doing such check here we cover both UPDATE and MULTI-UPDATE cases. sql/mysql_priv.h: Renamed check_if_key_used() to is_key_used(). sql/opt_range.cc: Renamed check_if_key_used()/QUICK_SELECT_I::check_if_keys_used() to is_key_used()/QUICK_SELECT_I::is_keys_used(). sql/opt_range.h: Renamed QUICK_SELECT_I::check_if_keys_used() method to is_keys_used(), also updated comment describing it to reflect its extended semantics (this change was caused by change in check_if_key_used()/is_key_used() routine semantics). sql/sql_trigger.cc: Introduced Table_triggers_list::is_updated_in_before_update_triggers() method which is needed for checking if field of subject table can be changed in before update trigger. sql/sql_trigger.h: Table_triggers_list: Removed has_before_update_triggers() method which is not used any longer. Added declaration of is_updated_in_before_update_triggers() which is needed for checking if field of subject table can be changed by before update trigger. sql/sql_update.cc: safe_update_on_fly(): check_if_key_used() routine and check_if_keys_used() method were renamed to is_key_used()/is_keys_used(). Now cases when trigger updates fields which are part of key used for filtering rows for update are caught directly in is_key_used(). This also allows to cover both UPDATE and MULTI-UPDATE cases.	20 years ago

unknown	0e47753ffd	After merge fixes for patch solving bug#18437 "Wrong values inserted with a before update trigger on NDB table". Two main changes: - We use TABLE::read_set/write_set bitmaps for marking fields used by statement instead of Field::query_id in 5.1. - Now when we mark columns used by statement we take into account columns used by table's triggers instead of marking all columns as used if table has triggers. mysql-test/r/federated.result: Changed test in order to make it work with RBR. RBR changes the way in which we execute "DELETE FROM t1" statement - we don't use handler::delete_all_rows() method if RBR is enabled (see bug#19066). As result federated engine produces different sequences of statements for remote server in non-RBR and in RBR cases. And this changes order of the rows inserted by following INSERT statements. mysql-test/t/federated.test: Changed test in order to make it work with RBR. RBR changes the way in which we execute "DELETE FROM t1" statement - we don't use handler::delete_all_rows() method if RBR is enabled (see bug#19066). As result federated engine produces different sequences of statements for remote server in non-RBR and in RBR cases. And this changes order of the rows inserted by following INSERT statements. sql/ha_partition.cc: Added handling of HA_EXTRA_WRITE_CAN_REPLACE/HA_EXTRA_WRITE_CANNOT_REPLACE to ha_partition::extra(). sql/item.cc: Adjusted comment after merge. In 5.1 we use TABLE::read_set/write_set bitmaps instead of Field::query_id for marking columns used. sql/log_event.cc: Write_rows_log_event::do_before_row_operations(): Now we explicitly inform handler that we want to replace rows so it can promote operation done by write_row() to replace. sql/mysql_priv.h: Removed declaration of mark_fields_used_by_triggers_for_insert_stmt() which is no longer used (we have TABLE::mark_columns_needed_for_insert() instead). sql/sql_insert.cc: Adjusted code after merge. Get rid of mark_fields_used_by_triggers_for_insert_stmt() as now we use TABLE::mark_columns_needed_for_insert() for the same purprose. Aligned places where we call this method with places where we call mark_fields_used_by_triggers_for_insert() in 5.0. Finally we no longer need to call handler::extra(HA_EXTRA_WRITE_CAN_REPLACE) in case of REPLACE statement since in 5.1 write_record() marks all columns as used before doing actual row replacement. sql/sql_load.cc: Adjusted code after merge. In 5.1 we use TABLE::mark_columns_needed_for_insert() instead of mark_fields_used_by_triggers_for_insert_stmt() routine. We also no longer need to call handler::extra(HA_EXTRA_RETRIEVE_ALL_COLS) if we execute LOAD DATA REPLACE since in 5.1 write_record() will mark all columns as used before doing actual row replacement. sql/sql_trigger.cc: Table_triggers_list::mark_fields_used(): We use TABLE::read_set/write_set bitmaps for marking fields used instead of Field::query_id in 5.1. sql/sql_trigger.h: TABLE::mark_columns_needed_for_* methods no longer need to be friends of Table_triggers_list class as intead of dirrectly accessing its private members they can use public Table_triggers_list::mark_fields_used() method. Also Table_triggers)list::mark_fields_used() no longer needs THD argument. sql/table.cc: TABLE::mark_columns_needed_for_*(): Now we mark columns which are really used by table's triggers instead of marking all columns as used if table has triggers.	20 years ago
unknown	ae9724cce1	Fix for bug#18437 "Wrong values inserted with a before update trigger on NDB table". SQL-layer was not marking fields which were used in triggers as such. As result these fields were not always properly retrieved/stored by handler layer. So one might got wrong values or lost changes in triggers for NDB, Federated and possibly InnoDB tables. This fix solves the problem by marking fields used in triggers appropriately. Also this patch contains the following cleanup of ha_ndbcluster code: We no longer rely on reading LEX::sql_command value in handler in order to determine if we can enable optimization which allows us to handle REPLACE statement in more efficient way by doing replaces directly in write_row() method without reporting error to SQL-layer. Instead we rely on SQL-layer informing us whether this optimization applicable by calling handler::extra() method with HA_EXTRA_WRITE_CAN_REPLACE flag. As result we no longer apply this optimzation in cases when it should not be used (e.g. if we have on delete triggers on table) and use in some additional cases when it is applicable (e.g. for LOAD DATA REPLACE). Finally this patch includes fix for bug#20728 "REPLACE does not work correctly for NDB table with PK and unique index". This was yet another problem which was caused by improper field mark-up. During row replacement fields which weren't explicity used in REPLACE statement were not marked as fields to be saved (updated) so they have retained values from old row version. The fix is to mark all table fields as set for REPLACE statement. Note that in 5.1 we already solve this problem by notifying handler that it should save values from all fields only in case when real replacement happens. include/my_base.h: Added HA_EXTRA_WRITE_CAN_REPLACE, HA_EXTRA_WRITE_CANNOT_REPLACE - new parameters for ha_extra() method. We use them to inform handler that write_row() which tries to insert new row into the table and encounters some already existing row with same primary/unique key can replace old row with new row instead of reporting error. mysql-test/r/federated.result: Additional test for bug#18437 "Wrong values inserted with a before update trigger on NDB table". mysql-test/r/ndb_replace.result: Added test for bug #20728 "REPLACE does not work correctly for NDB table with PK and unique index". Updated wrong results from older test. mysql-test/t/federated.test: Additional test for bug#18437 "Wrong values inserted with a before update trigger on NDB table". mysql-test/t/ndb_replace.test: Added test for bug #20728 "REPLACE does not work correctly for NDB table with PK and unique index". sql/ha_ndbcluster.cc: We no longer rely on reading LEX::sql_command value in handler in order to determine if we can enable optimization which allows us to handle REPLACE statement in more efficient way by doing replaces directly in write_row() method without reporting error to SQL-layer. Instead we rely on SQL-layer informing us whether this optimization applicable by calling handler::extra() method with HA_EXTRA_WRITE_CAN_REPLACE flag. As result we no longer apply this optimization in cases when it should not be used (e.g. if we have on delete triggers on table) and use in some additional cases when it is applicable (e.g. for LOAD DATA REPLACE). sql/item.cc: Item_trigger_field::setup_field(): Added comment explaining why we don't set Field::query_id in this method. sql/mysql_priv.h: mysql_alter_table() function no longer takes handle_duplicates argument. Added declaration of mark_fields_used_by_triggers_for_insert_stmt() function. sql/sql_delete.cc: Mark fields which are used by ON DELETE triggers so handler will retrieve values for these fields. sql/sql_insert.cc: Explicitly inform handler that we are doing REPLACE (using ha_extra() method) in cases when it can promote insert operation done by write_row() to replace. Also when we do REPLACE we want to store values for all columns so we should inform handler about it. Finally we should mark fields used by ON UPDATE/ON DELETE triggers as such so handler can properly retrieve/restore values in these fields during execution of REPLACE and INSERT ... ON DUPLICATE KEY UPDATE statements. sql/sql_load.cc: Explicitly inform handler that we are doing LOAD DATA REPLACE (using ha_extra() method) in cases when it can promote insert operation done by write_row() to replace. Also when we do replace we want to save (replace) values for all columns so we should inform handler about it. Finally to properly execute LOAD DATA for table with triggers we should mark fields used by ON INSERT triggers as such so handler can properly store values for these fields. sql/sql_parse.cc: mysql_alter_table() function no longer takes handle_duplicates argument. sql/sql_table.cc: Got rid of handle_duplicates argument in mysql_alter_table() and copy_data_between_tables() functions. These functions were always called with handle_duplicates == DUP_ERROR and thus contained dead (and probably incorrect) code. sql/sql_trigger.cc: Added Table_triggers_list::mark_fields_used() method which is used to mark fields read/set by triggers as such so handlers will be able properly retrieve/store values in these fields. sql/sql_trigger.h: Table_triggers_list: Added mark_fields_used() method which is used to mark fields read/set by triggers as such so handlers will be able properly retrieve/store values in these fields. To implement this method added 'trigger_fields' member which is array of lists linking items for all fields used in triggers grouped by event and action time. sql/sql_update.cc: Mark fields which are used by ON UPDATE triggers so handler will retrieve and save values for these fields. mysql-test/r/ndb_trigger.result: Added test for bug#18437 "Wrong values inserted with a before update trigger on NDB table". mysql-test/t/ndb_trigger.test: Added test for bug#18437 "Wrong values inserted with a before update trigger on NDB table".	20 years ago
unknown	01d03e7b4b	This changeset is largely a handler cleanup changeset (WL#3281), but includes fixes and cleanups that was found necessary while testing the handler changes Changes that requires code changes in other code of other storage engines. (Note that all changes are very straightforward and one should find all issues by compiling a --debug build and fixing all compiler errors and all asserts in field.cc while running the test suite), - New optional handler function introduced: reset() This is called after every DML statement to make it easy for a handler to statement specific cleanups. (The only case it's not called is if force the file to be closed) - handler::extra(HA_EXTRA_RESET) is removed. Code that was there before should be moved to handler::reset() - table->read_set contains a bitmap over all columns that are needed in the query. read_row() and similar functions only needs to read these columns - table->write_set contains a bitmap over all columns that will be updated in the query. write_row() and update_row() only needs to update these columns. The above bitmaps should now be up to date in all context (including ALTER TABLE, filesort()). The handler is informed of any changes to the bitmap after fix_fields() by calling the virtual function handler::column_bitmaps_signal(). If the handler does caching of these bitmaps (instead of using table->read_set, table->write_set), it should redo the caching in this code. as the signal() may be sent several times, it's probably best to set a variable in the signal and redo the caching on read_row() / write_row() if the variable was set. - Removed the read_set and write_set bitmap objects from the handler class - Removed all column bit handling functions from the handler class. (Now one instead uses the normal bitmap functions in my_bitmap.c instead of handler dedicated bitmap functions) - field->query_id is removed. One should instead instead check table->read_set and table->write_set if a field is used in the query. - handler::extra(HA_EXTRA_RETRIVE_ALL_COLS) and handler::extra(HA_EXTRA_RETRIEVE_PRIMARY_KEY) are removed. One should now instead use table->read_set to check for which columns to retrieve. - If a handler needs to call Field->val() or Field->store() on columns that are not used in the query, one should install a temporary all-columns-used map while doing so. For this, we provide the following functions: my_bitmap_map old_map= dbug_tmp_use_all_columns(table, table->read_set); field->val(); dbug_tmp_restore_column_map(table->read_set, old_map); and similar for the write map: my_bitmap_map old_map= dbug_tmp_use_all_columns(table, table->write_set); field->val(); dbug_tmp_restore_column_map(table->write_set, old_map); If this is not done, you will sooner or later hit a DBUG_ASSERT in the field store() / val() functions. (For not DBUG binaries, the dbug_tmp_restore_column_map() and dbug_tmp_restore_column_map() are inline dummy functions and should be optimized away be the compiler). - If one needs to temporary set the column map for all binaries (and not just to avoid the DBUG_ASSERT() in the Field::store() / Field::val() methods) one should use the functions tmp_use_all_columns() and tmp_restore_column_map() instead of the above dbug_ variants. - All 'status' fields in the handler base class (like records, data_file_length etc) are now stored in a 'stats' struct. This makes it easier to know what status variables are provided by the base handler. This requires some trivial variable names in the extra() function. - New virtual function handler::records(). This is called to optimize COUNT() if (handler::table_flags() & HA_HAS_RECORDS()) is true. (stats.records is not supposed to be an exact value. It's only has to be 'reasonable enough' for the optimizer to be able to choose a good optimization path). - Non virtual handler::init() function added for caching of virtual constants from engine. - Removed has_transactions() virtual method. Now one should instead return HA_NO_TRANSACTIONS in table_flags() if the table handler DOES NOT support transactions. - The 'xxxx_create_handler()' function now has a MEM_ROOT_root argument that is to be used with 'new handler_name()' to allocate the handler in the right area. The xxxx_create_handler() function is also responsible for any initialization of the object before returning. For example, one should change: static handler myisam_create_handler(TABLE_SHARE table) { return new ha_myisam(table); } -> static handler myisam_create_handler(TABLE_SHARE table, MEM_ROOT mem_root) { return new (mem_root) ha_myisam(table); } - New optional virtual function: use_hidden_primary_key(). This is called in case of an update/delete when (table_flags() and HA_PRIMARY_KEY_REQUIRED_FOR_DELETE) is defined but we don't have a primary key. This allows the handler to take precisions in remembering any hidden primary key to able to update/delete any found row. The default handler marks all columns to be read. - handler::table_flags() now returns a ulonglong (to allow for more flags). - New/changed table_flags() - HA_HAS_RECORDS Set if ::records() is supported - HA_NO_TRANSACTIONS Set if engine doesn't support transactions - HA_PRIMARY_KEY_REQUIRED_FOR_DELETE Set if we should mark all primary key columns for read when reading rows as part of a DELETE statement. If there is no primary key, all columns are marked for read. - HA_PARTIAL_COLUMN_READ Set if engine will not read all columns in some cases (based on table->read_set) - HA_PRIMARY_KEY_ALLOW_RANDOM_ACCESS Renamed to HA_PRIMARY_KEY_REQUIRED_FOR_POSITION. - HA_DUPP_POS Renamed to HA_DUPLICATE_POS - HA_REQUIRES_KEY_COLUMNS_FOR_DELETE Set this if we should mark ALL key columns for read when when reading rows as part of a DELETE statement. In case of an update we will mark all keys for read for which key part changed value. - HA_STATS_RECORDS_IS_EXACT Set this if stats.records is exact. (This saves us some extra records() calls when optimizing COUNT(*)) - Removed table_flags() - HA_NOT_EXACT_COUNT Now one should instead use HA_HAS_RECORDS if handler::records() gives an exact count() and HA_STATS_RECORDS_IS_EXACT if stats.records is exact. - HA_READ_RND_SAME Removed (no one supported this one) - Removed not needed functions ha_retrieve_all_cols() and ha_retrieve_all_pk() - Renamed handler::dupp_pos to handler::dup_pos - Removed not used variable handler::sortkey Upper level handler changes: - ha_reset() now does some overall checks and calls ::reset() - ha_table_flags() added. This is a cached version of table_flags(). The cache is updated on engine creation time and updated on open. MySQL level changes (not obvious from the above): - DBUG_ASSERT() added to check that column usage matches what is set in the column usage bit maps. (This found a LOT of bugs in current column marking code). - In 5.1 before, all used columns was marked in read_set and only updated columns was marked in write_set. Now we only mark columns for which we need a value in read_set. - Column bitmaps are created in open_binary_frm() and open_table_from_share(). (Before this was in table.cc) - handler::table_flags() calls are replaced with handler::ha_table_flags() - For calling field->val() you must have the corresponding bit set in table->read_set. For calling field->store() you must have the corresponding bit set in table->write_set. (There are asserts in all store()/val() functions to catch wrong usage) - thd->set_query_id is renamed to thd->mark_used_columns and instead of setting this to an integer value, this has now the values: MARK_COLUMNS_NONE, MARK_COLUMNS_READ, MARK_COLUMNS_WRITE Changed also all variables named 'set_query_id' to mark_used_columns. - In filesort() we now inform the handler of exactly which columns are needed doing the sort and choosing the rows. - The TABLE_SHARE object has a 'all_set' column bitmap one can use when one needs a column bitmap with all columns set. (This is used for table->use_all_columns() and other places) - The TABLE object has 3 column bitmaps: - def_read_set Default bitmap for columns to be read - def_write_set Default bitmap for columns to be written - tmp_set Can be used as a temporary bitmap when needed. The table object has also two pointer to bitmaps read_set and write_set that the handler should use to find out which columns are used in which way. - count() optimization now calls handler::records() instead of using handler->stats.records (if (table_flags() & HA_HAS_RECORDS) is true). - Added extra argument to Item::walk() to indicate if we should also traverse sub queries. - Added TABLE parameter to cp_buffer_from_ref() - Don't close tables created with CREATE ... SELECT but keep them in the table cache. (Faster usage of newly created tables). New interfaces: - table->clear_column_bitmaps() to initialize the bitmaps for tables at start of new statements. - table->column_bitmaps_set() to set up new column bitmaps and signal the handler about this. - table->column_bitmaps_set_no_signal() for some few cases where we need to setup new column bitmaps but don't signal the handler (as the handler has already been signaled about these before). Used for the momement only in opt_range.cc when doing ROR scans. - table->use_all_columns() to install a bitmap where all columns are marked as use in the read and the write set. - table->default_column_bitmaps() to install the normal read and write column bitmaps, but not signaling the handler about this. This is mainly used when creating TABLE instances. - table->mark_columns_needed_for_delete(), table->mark_columns_needed_for_delete() and table->mark_columns_needed_for_insert() to allow us to put additional columns in column usage maps if handler so requires. (The handler indicates what it neads in handler->table_flags()) - table->prepare_for_position() to allow us to tell handler that it needs to read primary key parts to be able to store them in future table->position() calls. (This replaces the table->file->ha_retrieve_all_pk function) - table->mark_auto_increment_column() to tell handler are going to update columns part of any auto_increment key. - table->mark_columns_used_by_index() to mark all columns that is part of an index. It will also send extra(HA_EXTRA_KEYREAD) to handler to allow it to quickly know that it only needs to read colums that are part of the key. (The handler can also use the column map for detecting this, but simpler/faster handler can just monitor the extra() call). - table->mark_columns_used_by_index_no_reset() to in addition to other columns, also mark all columns that is used by the given key. - table->restore_column_maps_after_mark_index() to restore to default column maps after a call to table->mark_columns_used_by_index(). - New item function register_field_in_read_map(), for marking used columns in table->read_map. Used by filesort() to mark all used columns - Maintain in TABLE->merge_keys set of all keys that are used in query. (Simplices some optimization loops) - Maintain Field->part_of_key_not_clustered which is like Field->part_of_key but the field in the clustered key is not assumed to be part of all index. (used in opt_range.cc for faster loops) - dbug_tmp_use_all_columns(), dbug_tmp_restore_column_map() tmp_use_all_columns() and tmp_restore_column_map() functions to temporally mark all columns as usable. The 'dbug_' version is primarily intended inside a handler when it wants to just call Field:store() & Field::val() functions, but don't need the column maps set for any other usage. (ie:: bitmap_is_set() is never called) - We can't use compare_records() to skip updates for handlers that returns a partial column set and the read_set doesn't cover all columns in the write set. The reason for this is that if we have a column marked only for write we can't in the MySQL level know if the value changed or not. The reason this worked before was that MySQL marked all to be written columns as also to be read. The new 'optimal' bitmaps exposed this 'hidden bug'. - open_table_from_share() does not anymore setup temporary MEM_ROOT object as a thread specific variable for the handler. Instead we send the to-be-used MEMROOT to get_new_handler(). (Simpler, faster code) Bugs fixed: - Column marking was not done correctly in a lot of cases. (ALTER TABLE, when using triggers, auto_increment fields etc) (Could potentially result in wrong values inserted in table handlers relying on that the old column maps or field->set_query_id was correct) Especially when it comes to triggers, there may be cases where the old code would cause lost/wrong values for NDB and/or InnoDB tables. - Split thd->options flag OPTION_STATUS_NO_TRANS_UPDATE to two flags: OPTION_STATUS_NO_TRANS_UPDATE and OPTION_KEEP_LOG. This allowed me to remove some wrong warnings about: "Some non-transactional changed tables couldn't be rolled back" - Fixed handling of INSERT .. SELECT and CREATE ... SELECT that wrongly reset (thd->options & OPTION_STATUS_NO_TRANS_UPDATE) which caused us to loose some warnings about "Some non-transactional changed tables couldn't be rolled back") - Fixed use of uninitialized memory in ha_ndbcluster.cc::delete_table() which could cause delete_table to report random failures. - Fixed core dumps for some tests when running with --debug - Added missing FN_LIBCHAR in mysql_rm_tmp_tables() (This has probably caused us to not properly remove temporary files after crash) - slow_logs was not properly initialized, which could maybe cause extra/lost entries in slow log. - If we get an duplicate row on insert, change column map to read and write all columns while retrying the operation. This is required by the definition of REPLACE and also ensures that fields that are only part of UPDATE are properly handled. This fixed a bug in NDB and REPLACE where REPLACE wrongly copied some column values from the replaced row. - For table handler that doesn't support NULL in keys, we would give an error when creating a primary key with NULL fields, even after the fields has been automaticly converted to NOT NULL. - Creating a primary key on a SPATIAL key, would fail if field was not declared as NOT NULL. Cleanups: - Removed not used condition argument to setup_tables - Removed not needed item function reset_query_id_processor(). - Field->add_index is removed. Now this is instead maintained in (field->flags & FIELD_IN_ADD_INDEX) - Field->fieldnr is removed (use field->field_index instead) - New argument to filesort() to indicate that it should return a set of row pointers (not used columns). This allowed me to remove some references to sql_command in filesort and should also enable us to return column results in some cases where we couldn't before. - Changed column bitmap handling in opt_range.cc to be aligned with TABLE bitmap, which allowed me to use bitmap functions instead of looping over all fields to create some needed bitmaps. (Faster and smaller code) - Broke up found too long lines - Moved some variable declaration at start of function for better code readability. - Removed some not used arguments from functions. (setup_fields(), mysql_prepare_insert_check_table()) - setup_fields() now takes an enum instead of an int for marking columns usage. - For internal temporary tables, use handler::write_row(), handler::delete_row() and handler::update_row() instead of handler::ha_xxxx() for faster execution. - Changed some constants to enum's and define's. - Using separate column read and write sets allows for easier checking of timestamp field was set by statement. - Remove calls to free_io_cache() as this is now done automaticly in ha_reset() - Don't build table->normalized_path as this is now identical to table->path (after bar's fixes to convert filenames) - Fixed some missed DBUG_PRINT(.."%lx") to use "0x%lx" to make it easier to do comparision with the 'convert-dbug-for-diff' tool. Things left to do in 5.1: - We wrongly log failed CREATE TABLE ... SELECT in some cases when using row based logging (as shown by testcase binlog_row_mix_innodb_myisam.result) Mats has promised to look into this. - Test that my fix for CREATE TABLE ... SELECT is indeed correct. (I added several test cases for this, but in this case it's better that someone else also tests this throughly). Lars has promosed to do this.

SELECT in a mixed environment (This found some bugs that Mats is going to fix shortly) mysql-test/install_test_db.sh: Simplify ldata usage Added --tmpdir=. option to mysqld bootstrap (Removed some warnings when TMPDIR was wrongly set) mysql-test/mysql-test-run.pl: Added --tmpdir=. to bootstrap mysql-test/mysql-test-run.sh: Use copy instead of INSTALL_DB for master and slave databases. (Speeds up startup time a lot!) Remove snapshot directories at startup (removes some strange warnings) mysql-test/r/binlog_row_mix_innodb_myisam.result: Added testing of CREATE ...

Changed how mutex is allocated to make 'bitmap_free()' function simpler. mysys/thr_lock.c: Added 0x before thread pointers (for easier comparison of DBUG traces) sql/event.cc: Ensure 'use_all_columns()' is used for event tables Don't print warning that event table is damaged if it doesn't exists. sql/field.cc: Added ASSERT_COLUMN_MARKED_FOR_WRITE in all store() methods and ASSERT_COLUMN_MARKED_FOR_READ in all val() methods to catch wrong setting if table->read_set and table->write_set (Rest of changes are only indentation cleanups) sql/field.h: Removed Field->query_id (replaced by table->read_set and table->write_set) Removed Field->fieldnr (use Field->field_index instead) Removed Field->add_index (Use Field->flags instead) Add Field->part_of_key_not_clustered (for usage in opt_range.cc) sql/filesort.cc: Added paramater sort_postion to filesort() to force sorting by position instead of storing all fields in the result set. This allowed me to remove checking of sql_command. Create a temporary column bitmap for fields that are used by the sorting process. Use column bitmaps instead of query_id sql/ha_berkeley.cc: Update to 'newer' table handler interface sql/ha_berkeley.h: Update to 'newer' table handler interface sql/ha_federated.cc: Update to 'newer' table handler interface Only read columns that are needed from remote server. In case of eq ranges, don't generate two conditions in the WHERE clause (this can still be optimized, but would require a bigger code change) Use 'simpler to use' XXXX_LEN' macros A bit simpler logic in ::write_row() when creating statements. In update, only include test of fields actually read. (This greatly simplifies the queries sent by the federated engine) Similar changes done for delete_row() sql/ha_federated.h: Update to 'newer' table handler interface Changed XXX_LEN macros to use sizeof(...)-1, to simplify usage in ha_federated.cc Added HA_PRIMARY_KEY_REQUIRED_FOR_DELETE to tell MySQL to read all primary key columns in case of DELETE sql/ha_heap.cc: Update to 'newer' table handler interface sql/ha_heap.h: Update to 'newer' table handler interface sql/ha_innodb.cc: Update to 'newer' table handler interface - Update innobase_create_handler() to new interface - Removed HA_NOT_EXACT_COUNT (not needed) - Renamed HA_PRIMARY_KEY_ALLOW_RANDOM_ACCESS to HA_PRIMARY_KEY_REQUIRED_FOR_POSITION. - Prefixed base status variables with 'stats' - Use table column bitmaps instead of ha_get_bit_in_read_set() - Added ::reset(), with code from ::extra(HA_EXTRA_RESET) - Removed HA_EXTRA_RETRIVE_ALL_COLS and HA_EXTRA_RETRIEVE_PRIMARY_KEY as the table->read_set and table->write_set bitmaps now are accurate sql/ha_innodb.h: Update to 'newer' table handler interface - table_flags are now ulonglong - Added reset() method - Removed not needed ha_retrieve_all_cols() and ha_retrieve_all_pk() columns. - Made build_template() a class function to be able to easier access class variables sql/ha_myisam.cc: Update to 'newer' table handler interface sql/ha_myisam.h: Update to 'newer' table handler interface sql/ha_myisammrg.cc: Update to 'newer' table handler interface sql/ha_myisammrg.h: Update to 'newer' table handler interface sql/ha_ndbcluster.cc: Update to 'newer' table handler interface Fixed use_blob_value() to be accurate In ::complemented_read() we have to check both the read and write bitmap as the old code did mark all changed columns also in the read map Correct dumping of field data with DBUG_DUMP Prefix addresses in DBUG_PRINT with 0x Fixed usage of not initialized memory Update to use field->flags & FIELD_IN_ADD_INDEX instead of field->add_index. sql/ha_ndbcluster.h: Update to 'newer' table handler interface sql/ha_ndbcluster_binlog.cc: Mark usage of all columns in ndbcluster binlog tables false -> FALSE, true -> TRUE Use table->s->all_set instead of creating a temporary bitmap. sql/ha_partition.cc: Update to 'newer' table handler interface Added memroot to initialise_partitions() and related functions to get faster memory allocation. partition_create_handler() is now responsible for initialisation of the partition object Some trivial optimizations and indentation fixes Ensure that table_flags() are up to date Removed documentation for removed HA_EXTRA flags Fixed 'strange' usage of m_file[i] in new_handlers_from_part_info()that worked in current code 'by chance' sql/ha_partition.h: Update to 'newer' table handler interface sql/handler.cc: create_xxx handler now takes MEMROOT as an argument to simplify memory allocation. Much simpler get_new_handler() (Initialization of the object is now handled by the create method for the engine) Moved all allocation of bitmap handling to the TABLE object (in table.cc) Added column_bitmaps_signal() to signal column usage changes. Changed binlog_log_row() to use the exiusting all_set bitmap in the table object. Added ha_reset() function to test that the file object is ok at end of statement and call handler::reset() Added use_hidden_primary_key() to signal handler that we we are going to read and update + delete the row and the handler should thus remember the position for the row sql/handler.h: Added HA_NO_TRANSACTIONS, HA_PARTIAL_COLUMN_READ, HA_REQUIRES_KEY_COLUMNS_FOR_DELETE,HA_PRIMARY_KEY_REQUIRED_FOR_DELETE and HA_HAS_RECORDS Removed HA_NOT_EXACT_COUNT, HA_READ_RND_SAME HA_DUPP_POS -> HA_DUPLICATE_POS HA_NOT_EXACT_COUNT replaced by HA_STATS_RECORDS_IS_EXACT, HA_HAS_RECORDS and records() HA_PRIMARY_KEY_ALLOW_RANDOM_ACCESS renamed to HA_PRIMARY_KEY_REQUIRED_FOR_POSITION Added future row type 'ROW_TYPE_PAGES' Added MEM_ROOT to handlerton 'create' function Added ha_statistics, a structure for all status variable in the base handler class. Moved all status variables in the handler class into a stats structs to improve readability. ha_table_flags() is now a cached (not virtual) version of table_flags() reset() doesn't anymore call extra(HA_EXTRA_RESET) but is a function of it's own. Renamed dupp_ref to dup_ref Renamed not used handler::sortkey Moved read_set and write_set to TABLE structure handler::init() function added for cacheing of virtual constants from engine. sql/item.cc: Added register_field_in_read_map() for marking used columns in expression. This is used by filesort() for creating an optimal column bitmap while retrieving columns for sorting. Initalize value.cs_info.character_set_client to fix core dump bug with --debug set_query_id -> mark_used_columns Mark used columns in read_set OR write_set. sql/item.h: Removed reset_query_id_processor() as it's not needed anymore. Added register_field_in_read_map() Added extra argument to Item::walk() to indicate if we should also traverse sub queries. sql/item_cmpfunc.cc: Temporary mark used columns to be read/writable Update Item::walk to new interface sql/item_cmpfunc.h: Added extra argument to Item::walk() to indicate if we should also traverse sub queries. sql/item_func.cc: Update Item::walk() to new interface table_flags() -> ha_table_flags() sql/item_func.h: Update Item::walk() to new interface sql/item_row.cc: Update Item::walk() to new interface sql/item_row.h: Update Item::walk() to new interface sql/item_strfunc.h: Update Item::walk() to new interface sql/item_subselect.cc: Added Item_subselect::walk() (It was a bug it was missing before. Not sure what kind of bugs this could have caused) sql/item_subselect.h: Update Item::walk() to new interface sql/item_sum.cc: Update Item::walk() to new interface Updates for new handler interace sql/item_sum.h: Update Item::walk() to new interface sql/key.cc: Updates for new handler interace sql/log.cc: Mark all columns used for log tables Split options flag Ensured that second argument to trans_register_ha is a bool sql/log_event.cc: Fixed comments to be withing 79 characters Use OPTION_KEEP_LOG instead of OPTION_STATUS_NO_TRANS_UPDATE to remove wrong warnings Updates for new handler interface Use 0x%lx instead of %p (portability problem) sql/mysql_priv.h: Added OPTION_KEEP_LOG to indicate that we should replicate the binlog even on rollback Removed not used 'conds' argument to setup_tables sql/mysqld.cc: Indentation fixes and removed old comment sql/opt_range.cc: Update to new handler and bitmap interface. Fixed calls to cp_buffer_from_ref() and walk() (new argument). Create new temporary bitmaps for ror scans. (Needed because of handler changes and to get more accurate column bitmaps than before) Remove not needed file->ha_reset() call before file->close(). Some trivial optimization and indentation fixes. Use Field->part_of_key_not_clustered() to check if field is part of a key, instead of looping over all key parts. Added flag 'in_ror_merged_scan' to allow ::get_next() to know that we need a special column bitmap to only fetch pointer to record. This is needed because ror scan uses the same TABLE object but different file objects, which creates problem for the column bitmap handling. (This is a temporary solution. A better one would be to allocate an own TABLE object for ROR scans) Optimized bitmap handling in ror scans: - Start bitmap at position 0, not 1 - Use same bitmap size as in TABLE - Use table->read_set and table->write_set to create column bitmaps instead of looping over all fields in table sql/opt_range.h: Added 'in_ror_merged_scan' to indicate if we are doing a ROR scan Added temporary column bitmaps used in ROR scans sql/opt_sum.cc: Added get_ext_record_count() which is used in COUNT() optimization if handler has HA_HAS_RECORDS Note that we don't call this if handler has HA_STATS_RECORDS_IS_EXACT set. sql/protocol.cc: We need to mark columns as readable in ::store() as we sometimes return default value for fields to the user sql/records.cc: Updates for new handler interface sql/set_var.cc: Handle splitting OPTION_STATUS_NO_TRANS_UPDATE to two flags sql/share/errmsg.txt: Fixed wrong sql/sp.cc: Mark that we are using all columns for the proc table Update call to setup_tables() to use new prototype sql/sp_head.cc: Removed QQ comment sql/spatial.cc: Removed wrong QQ comment sql/sql_acl.cc: Mark that we need all columns for acl tables Supply memroot to some 'new' calls. Indentation fixes sql/sql_base.cc: set_query_id removed Ensure we call ha_reset() at end of each statement Mark read columns in read_set and changed columns in write_set (Before all columns was marked in read set) Fixed marking of some columns that was not proplerly marked before Maintain in TABLE->merge_keys set of all keys that are used in some way Removed not used 'conds' argument from setup_tables() Remove not used setting of 'dupp_field' in insert_fields() Added missing FN_LIBCHAR in mysql_rm_tmp_tables() (This has probably caused us to not properly remove temporary files after crash) sql/sql_bitmap.h: Added is_overlapping() sql/sql_class.cc: Slow_logs was not properly initialized, which could maybe cause extra/lost entries in slow log. set_query_id -> mark_used_columns Simpler variable usage in pack_row() (cleanup) Moved some variable declartion at start of function for better code readability sql/sql_class.h: Added enum_mark_columns Updated comments Renamed dupp_field -> dup_field Added virtual function 'can_rollback_data()' to select_insert() to be used in CREATE ... SELECT to optimize use of OPTION_STATUS_NO_TRANS_UPDATE. (This fixes a bug in CREATE ... SELECT where we did give wrong warnings when using non transacational tables) sql/sql_delete.cc: Updates to new handler interface Call table->mark_columns_needed_for_delete() to allow us to put additional columns in column usage maps if handler so requires. Call table->prepare_for_position() to tell handler that we are going to call ha_position(). Removed call to free_io_cache(). (io_cache is now removed in ha_reset()). Fixed calls to setup_tables() sql/sql_do.cc: Update call to setup_fields() sql/sql_handler.cc: Tell handler tables to always read all columns. Use temporary column map when storing value in field for later index usage sql/sql_help.cc: Makr all used fields to be read Update call to setup_fields() sql/sql_insert.cc: Tell handler we are going to update the auto_increment column dupp_field -> dup_field Set column usage bits for timestamp field. Call table->mark_columns_needed_for_insert() and table->mark_auto_increment_column() Removed not used argument from mysql_prepare_insert_check_table(). If we get an duplicate row on insert, change column map to read and write all columns while retrying the operatation. This is required by the definition of REPLACE and also ensures that fields that are only part of UPDATE are properly handled. This fixed a bug in NDB and REPLACE where REPLACE wrongly copied some column values from the replaced row. Setup new bitmaps for delayed insert rows Remove reseting of next_number_fields as it will be reset on next call to handler_insert() Fixed usage of thd->options and OPTION_STATUS_NO_TRANS_UPDATE. The issue was that one should not to reset this flag as it may be set by a previous statement. The way it was now used caused us to loose some warnings and get other wrong warnings when using non transactional tables mixed with transactional. I fixed it by introducing 'select_insert::can_rollback_data' to inform send_error() that the given statement can be rolled back (which in case of CREATE TABLE can always be done) Don't close tables created with CREATE ... SELECT but keep them in the table cache. Moved out MY_HOOKS from inside function (better readability) sql/sql_load.cc: Update to use new handler and column marking interface Update using setup_tables() sql/sql_olap.cc: Update calls to setup_tables Use enums instead of constants to setup_fields() sql/sql_parse.cc: Handle OPTION_KEEP_LOG: - Set it on CREATE TEMPORARY TABLE / DROP TABLE - Reset it when OPTION_STATUS_NO_TRANS_UPDATE is reset - Don't set it for CREATE ... SELECT (this is handled in select_create class) Remove reseting of OPTION_STATUS_NO_TRANS_UPDATE in begin_trans() as this should already be reset. If in autocommit mode, reset OPTION_KEEP_LOG and OPTION_STATUS_NO_TRANS_UPDATE to not give warnings in future commands sql/sql_partition.cc: Update walk() usage Trivial indentation fixes sql/sql_plugin.cc: Mark all columns as used for plugins sql/sql_prepare.cc: Added assert to find out hidden bugs in character_set_client (got an error in debug binary when this not set correctly) Updates for new handler interface Update calls to setup_fields() sql/sql_repl.cc: Indentation fixes sql/sql_select.cc: Update call to setup_tables() and setup_fields() Remove some old disabled code Update to new hadler interface Indentation cleanups Added column bitmaps for temporary tables. Remove updating of the removed slots in the Field class Added TABLE argument to cp_buffer_from_ref() (To be able to install temporary column maps) For internal temporary tables, use handler::write_row(), handler::delete_row() and handler::update_row() instead of handler::ha_xxxx() for faster execution. sql/sql_select.h: Indentaition fixes. Install temporary column usage maps when needed Added TABLE element to cp_buffer_from_ref() sql/sql_show.cc: Update to new handler interface Mark all columns used for internal tables. Style fixes. Added support for 'future' ROW_TYPE_PAGES. Don't allocate TMP_TABLE_PARAM with calloc. The 'init()' function will initialize the structure properly. sql/sql_table.cc: Update to new handler interface Simple my_snprintf -> strmake() Changed some constants to defines Don't test for NULL in primary key (as we a couple of line above force the PRIMARY KEY to be NOT NULL) Change field->add_index to use field->flags & FIELD_IN_ADD_INDEX Mark all columns as used for ALTER TABLE Style fixes Update call to filesort() sql/sql_trigger.h: Added friend functions to be able to test if triggers exists for table we are going to insert/update or delete in. sql/sql_udf.cc: Mark all columns as used for udf system table. sql/sql_union.cc: Update call to walk() Update to new handler interface sql/sql_update.cc: Remove query_id argument from compare_record() Use column bitmaps instead of query_id. We can't use compare_records() to skip updates for handlers that returns a partial column set and the read_set doesn't cover all columns in the write set, because compare_record() can't in this case know if a not read column changed value. Update call to setup_fields() Using separate column read and write sets allows for easier checking of timestamp field was set by statement. Removed call to free_io_cache() as this is now done in ha_reset() Call table->mark_columns_needed_for_update() and table->prepare_for_position() Style fixes sql/sql_view.cc: Style fixes sql/table.cc: Remove implicitely include 'errno.h' Remove code for building normalized path, as this is now identical to 'path' Remove field->fieldnr Added update of field->part_of_key_not_clustered() Create column bitmaps in TABLE and TABLE_SHARE Don't setup a temporary MEM_ROOT object as a thread specific variable for the handler. Instead we send the to-be-used MEMROOT to get_new_handler() Update to new handler interface Update call to walk() Added new functions: - st_table::clear_column_bitmaps() - st_table::prepare_for_position() - st_table::mark_columns_used_by_index() - st_table::restore_column_maps_after_mark_index() - st_table::mark_columns_used_by_index_no_reset() - st_table::mark_auto_increment_column() - st_table::mark_columns_needed_for_delete() - st_table::mark_columns_needed_for_update() - st_table::mark_columns_needed_for_insert() sql/table.h: Moved column usage bitmaps from handler to TABLE Added to TABLE_SHARE all_set and column_bitmap_size Added to TABLE merge_keys, bitmap_init_values, def_read_set, def_write_set, tmp_set, read_set and write_set. Declared all new table column bitmap functions Added TABLE functions column_bitmaps_set(), column_bitmaps_set_no_signal(), use_all_columns() and default_column_bitmaps() Added functions: tmp_use_all_columns() and tmp_restore_column_map() to temporarly switch column bitmaps Added functions: dbug_tmp_use_all_columns() and dbug_tmp_restore_column_map() to temporarly switch column bitmaps to avoid asserts in Field::store() and Field::val(). sql/tztime.cc: Mark all columns as used for timezone tables storage/archive/ha_archive.cc: Update to new handler interface storage/archive/ha_archive.h: Update to new handler interface storage/blackhole/ha_blackhole.cc: Update to new handler interface storage/blackhole/ha_blackhole.h: Update to new handler interface removed not needed flag HA_DUPP_POS storage/csv/ha_tina.cc: Update to new handler interface storage/csv/ha_tina.h: Update to new handler interface storage/example/ha_example.cc: Update to new handler interface storage/example/ha_example.h: Update to new handler interface storage/heap/hp_extra.c: Added heap_reset() (Required by new handler interface) storage/heap/hp_test2.c: Use heap_reset() storage/myisam/ft_boolean_search.c: Fixed compiler warning storage/myisam/mi_extra.c: Added mi_reset() (Required by new handler interface) storage/myisam/mi_search.c: Fixed DBUG_PRINT messages to use 0x%lx instead of %lx storage/myisam/mi_test2.c: Use mi_reset() storage/myisam/myisampack.c: Use mi_reset() storage/myisammrg/myrg_extra.c: Added myrg_reset() (Required by new handler interface) unittest/mysys/base64.t.c: Include my_global.h Don't include implictely include file 'stdlib.h'	20 years ago
unknown	f8386dfa48	Fix for bug #13525 "Rename table does not keep info of triggers". Let us transfer triggers associated with table when we rename it (but only if we are not changing database to which table belongs, in the latter case we will emit error). mysql-test/r/trigger.result: Added test for bug #13525 "Rename table does not keep info of triggers". mysql-test/t/trigger.test: Added test for bug #13525 "Rename table does not keep info of triggers". sql/sql_rename.cc: rename_tables(): Now after renaming table's .FRM file and updating handler data we call Table_triggers_list::change_table_name() which is reponsible for updating .TRG and .TRN files. sql/sql_table.cc: mysql_alter_table(): Now in case when ALTER should rename table we call Table_triggers_list::change_table_name() which is responsible for updating .TRG and .TRN files after renaming table. sql/sql_trigger.cc: Added Table_triggers_list::change_table_name() method and change_table_name_in_triggers()/trignames() methods responsible for updating .TRG and .TRN files for table during its renaming. Two small cleanups - removed versioning for .TRG files (since it was not working before anyway) and emphasized that type of lock specified in tables list is unimportant for DROP TABLE (since this statement uses name-locking). sql/sql_trigger.h: Table_triggers_list: Added on_table_names_list member to store pointers and lenghts of "ON table_name" parts in triggers' definitions to be able easily change them during RENAME TABLE. Added change_table_name() method and change_table_name_in_trignames/triggers() helper methods responsible for updating .TRG and .TRN files. sql/sql_yacc.yy: trigger_tail: To be able properly update triggers' definitions with new table names when renaming tables we need to know where in CREATE TRIGGER statement "ON db_name.table_name" part resides. Small cleanup - let us emphasize that for CREATE TRIGGER statement lock type which is specified in table list is unimportant since name-locking is used.	20 years ago
unknown	8f395ebbfa	Fix for the following bugs: - BUG#15166: Wrong update permissions required to execute triggers - BUG#15196: Wrong select permission required to execute triggers The idea of the fix is to check necessary privileges in Item_trigger_field::fix_fields(), instead of having "special variables" technique. To achieve this, we should pass to an Item_trigger_field instance a flag, which will indicate the usage/access type of this trigger variable. mysql-test/r/trigger-grant.result: Update the result file. mysql-test/t/trigger-grant.test: Add test cases for BUG#15166 and BUG#15196 sql/item.cc: Item_trigger_field: check appropriate (SELECT/UPDATE) privilege in fix_fields(). sql/item.h: Add a flag to specify access type for trigger field. sql/sql_trigger.cc: "Special variable" technique of checking privileges for NEW/OLD variables was replaced by checking table- and column-level privileges in Item_trigger_field::fix_fields(). sql/sql_trigger.h: "Special variable" technique of checking privileges for NEW/OLD variables was replaced by checking table- and column-level privileges in Item_trigger_field::fix_fields(). sql/sql_yacc.yy: Specify access type for trigger fields.	20 years ago
unknown	361977c0da	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.

unknown	d5303b8ab8	Fix for bug #12704 "Server crashes during trigger execution". This bug occurs when some trigger for table used by DML statement is created or changed while statement was waiting in lock_tables(). In this situation prelocking set which we have calculated becames invalid which can easily lead to errors and even in some cases to crashes. With proposed patch we no longer silently reopen tables in lock_tables(), instead caller of lock_tables() becomes responsible for reopening tables and recalculation of prelocking set. mysql-test/t/trigger.test: Added tests for bug #12704 "Server crashes during trigger execution". Unfortunately these tests rely on the order in which tables are locked by statement so they are non-determenistic and therefore should be disabled. sql/lock.cc: mysql_lock_tables(): Now instead of always reopening altered or dropped tables by itself mysql_lock_tables() can notify upper level and rely on caller doing this. sql/mysql_priv.h: Now mysql_lock_tables() can either reopen deleted or altered tables by itself or notify caller about such situation through 'need_reopen' argument and rely on it in this. Also lock_tables() has new 'need_reopen' out parameter through which it notifies caller that some tables were altered or dropped so he needs to reopen them (and rebuild prelocking set some triggers may change or simply appear). sql/sp.cc: sp_add_used_routine(): To be able to restore LEX::sroutines_list to its state right after parsing we now adjust LEX::sroutines_list_own_last/sroutines_list_own_elements when we add directly used routine. sp_remove_not_own_routines(): Added procedure for restoring LEX::sroutines/sroutines_list to their state right after parsing (by throwing out non-directly used routines). sp_cache_routines_and_add_tables_for_view()/sp_update_stmt_used_routines(): We should use LEX::sroutines_list instead of LEX::sroutines as source of routines used by view, since LEX::sroutines is not availiable for view on second attempt to open it (see comment in open_tables() about it). sql/sp.h: sp_remove_not_own_routines(): Added procedure for restoring LEX::sroutines/sroutines_list to their state right after parsing (by throwing out non-directly used routines). sql/sp_head.cc: Removed assert which is no longer always true. sql/sql_base.cc: reopen_table(): When we re-open table and do shallow copy of TABLE object we should adjust pointers to it in associated Table_triggers_list object. Removed nil operation. open_tables(): Now this function is able to rebuild prelocking set for statement if it is needed. It also correctly handles FLUSH TABLES which may occur during its execution. lock_tables(): Instead of allowing mysql_lock_tables() to silently reopen altered or dropped tables let us notify caller and rely on that it will do reopen itself. This solves the problem when trigger suddenly appears or changed during mysq_lock_tables(). close_tables_for_reopen(): Added routine for properly preparing for reopening of tables and recalculation of set of prelocked tables. sql/sql_handler.cc: Here we let mysql_lock_tables() to reopen dropped or altered tables by itself. sql/sql_insert.cc: Here we let mysql_lock_tables() to reopen dropped or altered tables by itself. sql/sql_lex.cc: LEX: Added 'sroutines_list_own_last' and 'sroutines_list_own_elements' members which are used for keeping state in which 'sroutines_list' was right after statement parsing (and for restoring of this list to this state). sql/sql_lex.h: LEX: Added 'sroutines_list_own_last' and 'sroutines_list_own_elements' members which are used for keeping state in which 'sroutines_list' was right after statement parsing (and for restoring of this list to this state). Added chop_off_not_own_tables() method to simplify throwing away list of implicitly used (prelocked) tables. sql/sql_prepare.cc: Now instead of silently reopening altered or dropped tables in lock_tables() we notify caller and rely on that the caller will reopen tables. sql/sql_table.cc: Here we let mysql_lock_tables() to reopen dropped or altered tables by itself. sql/sql_trigger.cc: Added Table_triggers_list::set_table() method to adjust Table_triggers_list to new pointer to TABLE instance. sql/sql_trigger.h: Added Table_triggers_list::set_table() method to adjust Table_triggers_list to new pointer to TABLE instance. sql/sql_update.cc: Now instead of silently reopening altered or dropped tables in lock_tables() we notify caller and rely on that the caller will reopen tables.	21 years ago

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

Also now we don't call after trigger in case when we have failed to inserted/update or delete row. Trigger failure should stop statement execution. I have not properly tested handling of errors which happen inside of triggers in this patch, since it is simplier to do this once we will be able to access tables from triggers. mysql-test/r/trigger.result: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ...

Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field::setup_field()/fix_fields() were changed to implement this approach. sql/item.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field: - Added field_idx member to store index of Field object corresponding to this Item in TABLE::field array. - Added triggers member to be able to access to parent Table_trigger_list object from fix_fields() method. - setup_field() no longer needs to know for which type of event this trigger is, since it does not make decision Field for which buffer (record[0] or record[1] is appropriate for this Item_trigger_field) sql/mysql_priv.h: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_base.cc: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_delete.cc: mysql_delete(): Now we stop statement execution if one of triggers failed, we also don't execute after delete trigger if we failed to delete row from the table (We also pass information about which buffer contains old version of row to process_triggers()). multi_delete::send_data()/do_deletes(): Now we also invoke triggers in case of multi-delete. sql/sql_insert.cc: mysql_insert(): Moved invocation of before triggers to fill_record_n_invoke_before_triggers() method. After triggers are now executed as part of write_record(). (as nice side effect now we also stop statement execution if one of triggers fail). write_record(): Invoke after insert trigger after performing insert. Also invoke proper triggers if insert is converted to update or conflicting row is deleted. Cleaned up error handling a bit - no sense to report error via handler::print_error if it was not generated by handler method and was reported before. Also now we will execute after trigger only if we really have written row to the table. select_insert::send_data()/store_values(): We should also execute INSERT triggers for INSERT ... SELECT statement. sql/sql_load.cc: read_fixed_length()/read_sep_field(): We should execute INSERT triggers when processing LOAD DATA statement. Small cleanup in auto-increment related code. Also moved check for thd->killed which is used to abort LOAD DATA in case of problems in 'traditional' mode to better place.. sql/sql_trigger.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Table_triggers_list methods were changed to implement this approach (see also comments for sql_trigger.h). sql/sql_trigger.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Changed Table_triggers_list to implement this new approach: - Added record1_field member to store array of Field objects bound to TABLE::record[1] buffer (instead of existing old_field member) - Added new_field member and changed meaning of old_field member. During trigger execution they should point to arrays of Field objects bound to buffers holding new and old versions of row respectively. - Added 'table' member to be able to get access to TABLE instance (for which this trigger list object was created) from process_triggers() method. - Now process_triggers() method sets old_field and new_field members properly before executing triggers body (basing on new old_row_is_record1 parameter value). - Renamed prepare_old_row_accessors_method() to prepare_record1_accessors() Also added has_before_update_triggers() method which allows to check whenever any before update triggers exist for table. sql/sql_update.cc: mysql_update(): Now we invoke before triggers in fill_record_n_invoke_before_triggers() method. Also now we abort statement execution when one of triggers fail. safe_update_on_fly(): When we are trying to understand if we can update first table in multi update on the fly we should take into account that BEFORE UPDATE trigger can change field values. multi_update::send_data()/do_updates() We should execute proper triggers when doing multi-update (in both cases when we do it on the fly and using temporary tables).	21 years ago

unknown	ac9f68b9fa	Better approach for prelocking of tables for stored routines execution and some SP-related cleanups. - We don't have separate stage for calculation of list of tables to be prelocked and doing implicit LOCK/UNLOCK any more. Instead we calculate this list at open_tables() and do implicit LOCK in lock_tables() (and UNLOCK in close_thread_tables()). Also now we support cases when same table (with same alias) is used several times in the same query in SP. - Cleaned up execution of SP. Moved all common code which handles LEX and does preparations before statement execution or complex expression evaluation to auxilary sp_lex_keeper class. Now all statements in SP (and corresponding instructions) that evaluate expression which can contain subquery have their own LEX. mysql-test/r/lock.result: Replaced wrong error code with the correct one after fixing bug in SP-locking. mysql-test/r/mysqldump.result: Added dropping of view which is used in test to its beginning. mysql-test/r/sp.result: Added tests for improved SP-locking. 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.	21 years ago
unknown	c3da2d12f7	Fix for bug #5888 "Triggers with nonexistent columns cause packets out of order". (final version) Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger. This allows easily check all references to fields in old/new version of row in trigger during execution of CREATE TRIGGER statement (this is more courtesy for users since we can't check everything anyway). We also report that such reference is bad by returning error from Item_trigger_field::fix_fields() method (instead of setup_field()) This means that if trigger is broken we will bark during trigger execution instead of trigger definition parsing at table open. (i.e. now we allow to open tables with broken triggers). mysql-test/r/trigger.result: Added test which attempts to create trigger for table referencing to field which does not exist in this table. mysql-test/t/trigger.test: Added test which attempts to create trigger for table referencing to field which does not exist in this table. sql/item.cc: Item_trigger_field::setup_field() now returns void. If any error will occur we will report it at fix_fields() stage. sql/item.h: Item_trigger_field: - Added next_trg_field member for linking all such objects in trigger in one list. - Also setup_field() now returns void. If any error will occur we will report it at fix_fields() stage. sql/mysql_priv.h: Added SQL_LIST::push_back() method which allows to add another SQL_LIST to the end of this SQL_LIST. sql/sp_head.cc: sp_head::init()/reset_lex()/restore_lex(): In order to fill global LEX::trg_table_fields (list of all Item_trigger_field objects for trigger) we should init the same list in LEX of substatement before its parsing and merge it to global list after parsing. sql/sp_head.h: sp_instr_trigger_field: Made trigger_field member public to be able to add it more easily to global list of all Item_trigger_field objects in trigger. sql/sql_lex.cc: LEX::trg_table was removed. sql/sql_lex.h: Now we are binding Item_trigger_field's to TABLE object by passing through specially constructed list of all such objects in this trigger instead of doing this during trigger definition parsing at table open. So we no longer need LEX::trg_table, we use LEX::trg_table_fields list instead. sql/sql_parse.cc: mysql_execute_command(): Since now we use trigger body for some checks in mysql_create_or_drop_trigger() we should destroy it only after calling this function. sql/sql_trigger.cc: Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger. This allows easily check all references to fields in old/new version of row in trigger during execution of CREATE TRIGGER statement (this is more courtesy for users since we can't check everything anyway). We also report that such reference is bad by returning error from Item_trigger_field::fix_fields() method (instead of setup_field()) This means that if trigger is broken we will bark during trigger execution instead of trigger definition parsing at table open. (i.e. now we allow to open tables with broken triggers). Table_triggers_list::prepare_old_row_accessors() method was added to be able to reuse code creating Field objects referencing TABLE::record[1] buffer instead of TABLE::record[0]. sql/sql_trigger.h: Added Table_triggers_list::prepare_old_row_accessors() method to be able to reuse code creating Field objects referencing to TABLE::record[1] instead of record[0]. sql/sql_yacc.yy: Now instead of performing binding of Item_trigger_field objects to TABLE object during trigger definition parsing at table open, we perform this binding by passing through specially constructed list of all such items in trigger. We also check value returned from memory allocation functions.	21 years ago
unknown	bb43e8317f	Fix for bug #5890 "Triggers fail for DELETE without WHERE". If we have DELETE with always true WHERE clause we should not use optimized delete_all_rows() method for tables with DELETE triggers, because in this case we will lose side-effect of deletion. mysql-test/r/trigger.result: Added test for bug #5890 "Triggers fail for DELETE without WHERE". mysql-test/t/trigger.test: Added test for bug #5890 "Triggers fail for DELETE without WHERE". sql/sql_delete.cc: mysql_delete(): We should not use optimized delete_all_rows() method for tables with DELETE triggers, because in this case we will lose side-effect of deletion. sql/sql_trigger.h: Added new Table_triggers_list::has_delete_triggers() method which allows to understand quickly if we have some DELETE triggers in our list.	21 years ago
unknown	52ac4935e7	WL#1218 "Triggers". Some very preliminary version of patch. Mostly needed for Monty for him getting notion what needed for triggers from new .FRM format. Things to be done: - Right placement of trigger's invocations - Right handling of errors in triggers (including transaction rollback) - Support for priviliges - Right handling of DROP/RENAME table (hope that it will be handled automatically with merging of .TRG into .FRM file) - Saving/restoring some information critical for trigger creation and replication with their definitions (e.g. sql_mode, creator, ...) - Replication Already has some known bugs so probably not for general review. include/mysqld_error.h: Added trigger related error codes. sql/Makefile.am: Added sql_trigger.* files to list of sources from which mysqld is built. sql/item.cc: Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item.h: Added enums for describing trigger properties.

Added two more SP instructions: - sp_instr_set_user_var for setting user variables in stored functions and triggers (we can't use sp_instr_stmt and "SET @a:=..." statement since it will close open tables and thus break execution of calling statement. - sp_instr_set_trigger_field for assignment to fields of row being updated/inserted in triggers sql/sp_head.h: Added new type of sp_head object - TYPE_ENUM_TRIGGER Added two more SP instructions: - sp_instr_set_user_var for setting user variables in stored functions and triggers (we can't use sp_instr_stmt and "SET @a:=..." statement since it will close open tables and thus break execution of calling statement. - sp_instr_set_trigger_field for assignment to fields of row being updated/inserted in triggers sql/sql_base.cc: Now freeing memory occupied by trigger related structures when closing tables. open_unireg_entry(): added loading of triggers for table. find_field_in_real_table() is now public since it required by Item_trigger_field in item.cc sql/sql_delete.cc: Added triggers invocation for DELETE (should be fixed for sure :)) sql/sql_insert.cc: Added triggers invocation for INSERT (should be fixed for sure :)) sql/sql_lex.cc: Added trg_new_row_fake_var variable pointer to which is used for distinguishing between assignment to NEW row field (when parsing trigger definition) and structured variable. Added initialization of LEX->trg_table to lex_start(). (When triggers are parsed during opening of table it points to table object.) sql/sql_lex.h: Added trigger related commands. Added st_trg_chistics structure describing properties of trigger being created (as struct and as LEX member). Added trg_new_row_fake_var variable pointer to which is used for distinguishing between assignment to NEW row field (when parsing trigger definition) and structured variable. Added LEX::trg_table which points to table being opened when we are parsing trigger definition while opening table. sql/sql_parse.cc: Added support for CREATE/DROP TRIGGER commands. sql/sql_table.cc: Cleanup. close_cached_table() always returns 0 and its result is not analyzed in most places so chenged its return type to void. sql/sql_update.cc: Added triggers invocation for UPDATE (should be fixed for sure :)) sql/sql_yacc.yy: Added support for CREATE/DROP TRIGGER statements. Added support for OLD/NEW row identifiers in trigger. Made assignment to user variables not to break execution of stored function or trigger. sql/table.h: Added TABLE::triggers member representing triggers for this table.	22 years ago
