unknown	13133087e4	BUG#21658: Crash when creating table with item in prepared statement that allocates memory in fix_fields We need to use an arena to indicate we are preparing a statement when loading partition function and parsing it as part of an open table. mysql-test/r/partition.result: Moved test case mysql-test/t/partition.test: Moved test case sql/item.cc: Shouldn't call change_item_tree in prepare statement phase even if arena was already activated sql/sql_partition.cc: We need to use an arena to indicate we are preparing a statement when loading partition function and parsing it as part of an open table. sql/table.cc: We need to use an arena to indicate we are preparing a statement when loading partition function and parsing it as part of an open table.	19 years ago
unknown	7a11df8c93	Fixed bug#21475: Wrongly applied constant propagation leads to a false comparison. A date can be represented as an int (like 20060101) and as a string (like "2006.01.01"). When a DATE/TIME field is compared in one SELECT against both representations the constant propagation mechanism leads to comparison of DATE as a string and DATE as an int. In this example it compares 2006 and 20060101 integers. Obviously it fails comparison although they represents the same date. Now the Item_bool_func2::fix_length_and_dec() function sets the comparison context for items being compared. I.e. if items compared as strings the comparison context is STRING. The constant propagation mechanism now doesn't mix items used in different comparison contexts. The context check is done in the Item_field::equal_fields_propagator() and in the change_cond_ref_to_const() functions. Also the better fix for bug 21159 is introduced. mysql-test/t/type_datetime.test: Added a test case for bug#21475: Wrongly applied constant propagation leads to a false comparison. mysql-test/r/type_datetime.result: Added a test case for bug#21475: Wrongly applied constant propagation leads to a false comparison. sql/sql_select.cc: Fixed bug#21475: Wrongly applied constant propagation leads to a false comparison.

unknown	35209c68ea	Fixed bug#12185: Data type aggregation may produce wrong result The Item::tmp_table_field_from_field_type() function creates Field_datetime object instead of Field_timestamp object for timestamp field thus always changing data type is a tmp table is used. The Field_blob object constructor which is used in the Item::tmp_table_field_from_field_type() is always setting packlength field of newly created blob to 4. This leads to changing fields data type for example from the blob to the longblob if a temporary table is used. The Item::make_string_field() function always converts Field_string objects to Field_varstring objects. This leads to changing data type from the char/binary to varchar/varbinary. Added appropriate Field_timestamp object constructor for using in the Item::tmp_table_field_from_field_type() function. Added Field_blob object constructor which sets pack length according to max_length argument. The Item::tmp_table_field_from_field_type() function now creates Field_timestamp object for a timestamp field. The Item_type_holder::display_length() now returns correct NULL length NULL length. The Item::make_string_field() function now doesn't change Field_string to Field_varstring in the case of Item_type_holder. The Item::tmp_table_field_from_field_type() function now uses the Field_blob constructor which sets packlength according to max_length. mysql-test/t/union.test: Added test case for bug#12185: Data type aggregation may produce wrong result Corrected test case after fix for bug#12185 mysql-test/t/innodb.test: Corrected test case after fix for bug#12185 mysql-test/r/union.result: Added test case for bug#12185: Data type aggregation may produce wrong result Corrected test case after fix for bug#12185 mysql-test/r/innodb.result: Corrected test case after fix for bug#12185 mysql-test/r/create.result: Corrected the test case after fixing bug#12185 sql/field.h: Fixed bug#12185: Data type aggregation may produce wrong result Added Field_blob object constructor which sets packlength according to max_length argument. sql/item.cc: Fixed bug#12185: Data type aggregation may produce wrong result The Item::make_string_field() function now doesn't change Field_string to Field_varstring in the case of Item_type_holder.

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. BitKeeper/etc/ignore: added mysys/test_bitmap include/base64.h: Removed my_global.h, as this must be included first in any program include/heap.h: Added heap_reset() (Required by new handler interface) include/my_base.h: Removed HA_EXTRA_RESET. MySQL will now call ::reset() instead of ::extra(HA_EXTRA_RESET). HA_EXTRA_RETRIVE_ALL_COLS and HA_EXTRA_RETRIVE_PRIMARY key are deleted as the column bitmaps makes these unnecessary include/my_bitmap.h: Remove my_pthread.h (should be included at upper level) Introduced my_bitmap_map typedef to make it the bitmap handling more like a black box Added bitmap_is_overlapping(), bitmap_test_and_clear(), bitmap_copy() and bitmap_cmp() Made bitmap_set_bit(), bitmap_flip_bit(), bitmap_clear_bit() return void include/myisam.h: Added mi_reset() (Required by new handler interface) include/myisammrg.h: Added myrg_reset() (Required by new handler interface) include/mysql_com.h: Added flag FIELD_IN_ADD_INDEX to be able to remove Field->add_index mysql-test/extra/binlog_tests/mix_innodb_myisam_binlog.test: 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.

unknown	1c6beaee06	Fixed bug#19077: A nested materialized derived table is used before being populated. The convert_constant_item() function converts constant items to ints on prepare phase to optimize execution speed. In this case it tries to evaluate subselect which contains a derived table and is contained in a derived table. All derived tables are filled only after all derived tables are prepared. So evaluation of subselect with derived table at the prepare phase will return a wrong result. A new flag with_subselect is added to the Item class. It indicates that expression which this item represents is a subselect or contains a subselect. It is set to 0 by default. It is set to 1 in the Item_subselect constructor for subselects. For Item_func and Item_cond derived classes it is set after fixing any argument in Item_func::fix_fields() and Item_cond::fix_fields accordingly.

unknown	3a0d0b4ce5	BUG#18492: mysqld reports ER_ILLEGAL_REFERENCE in --ps-protocol In the code that converts IN predicates to EXISTS predicates it is changing the select list elements to constant 1. Example : SELECT ... FROM ... WHERE a IN (SELECT c FROM ...) is transformed to : SELECT ... FROM ... WHERE EXISTS (SELECT 1 FROM ... HAVING a = c) However there can be no FROM clause in the IN subquery and it may not be a simple select : SELECT ... FROM ... WHERE a IN (SELECT f(..) AS c UNION SELECT ...) This query is transformed to : SELECT ... FROM ... WHERE EXISTS (SELECT 1 FROM (SELECT f(..) AS c UNION SELECT ...) x HAVING a = c) In the above query c in the HAVING clause is made to be an Item_null_helper (a subclass of Item_ref) pointing to the real Item_field (which is not referenced anywhere else in the query anymore). This is done because Item_ref_null_helper collects information whether there are NULL values in the result. This is OK for directly executed statements, because the Item_field pointed by the Item_null_helper is already fixed when the transformation is done. But when executed as a prepared statement all the Item instances are "un-fixed" before the recompilation of the prepared statement. So when the Item_null_helper gets fixed it discovers that the Item_field it points to is not fixed and issues an error. The remedy is to keep the original select list references when there are no tables in the FROM clause. So the above becomes : SELECT ... FROM ... WHERE EXISTS (SELECT c FROM (SELECT f(..) AS c UNION SELECT ...) x HAVING a = c) In this way c is referenced directly in the select list as well as by reference in the HAVING clause. So it gets correctly fixed even with prepared statements. And since the Item_null_helper subclass of Item_ref_null_helper is not used anywhere else it's taken out. mysql-test/r/ps_11bugs.result: Test case for the bug mysql-test/r/subselect.result: Explain updated because of the tranformation mysql-test/t/ps_11bugs.test: Testcase for the bug sql/item.cc: Taking out Item_null_helper as it's no longer needed sql/item.h: Taking out Item_null_helper as it's no longer needed sql/item_subselect.cc: The described change to the IN->EXISTS transformation	20 years ago

unknown	4b7c4cd27f	Fixed bug#18739: non-standard HAVING extension was allowed in strict ANSI sql mode. The SQL standard doesn't allow to use in HAVING clause fields that are not present in GROUP BY clause and not under any aggregate function in the HAVING clause. However, mysql allows using such fields. This extension assume that the non-grouping fields will have the same group-wise values. Otherwise, the result will be unpredictable. This extension allowed in strict MODE_ONLY_FULL_GROUP_BY sql mode results in misunderstanding of HAVING capabilities. The new error message ER_NON_GROUPING_FIELD_USED message is added. It says "non-grouping field '%-.64s' is used in %-.64s clause". This message is supposed to be used for reporting errors when some field is not found in the GROUP BY clause but have to be present there. Use cases for this message are this bug and when a field is present in a SELECT item list not under any aggregate function and there is GROUP BY clause present which doesn't mention that field. It renders the ER_WRONG_FIELD_WITH_GROUP error message obsolete as being more descriptive. The resolve_ref_in_select_and_group() function now reports the ER_NON_GROUPING_FIELD_FOUND error if the strict mode is set and the field for HAVING clause is found in the SELECT item list only. sql/share/errmsg.txt: Added the new ER_NON_GROUPING_FIELD_USED error message for the bug#14169. mysql-test/t/having.test: Added test case for the bug#18739: non-standard HAVING extension was allowed in strict ANSI sql mode. mysql-test/r/having.result: Added test case for the bug#18739: non-standard HAVING extension was allowed in strict ANSI sql mode. sql/sql_select.cc: Added TODO comment to change the ER_WRONG_FIELD_WITH_GROUP to more detailed ER_NON_GROUPING_FIELD_USED message. sql/item.cc: Fixed bug#18739: non-standard HAVING extension was allowed in strict ANSI sql mode.

unknown	a01d48f92e	Fix for BUG#16710. The bug was due to a missed case in the detection of whether an index can be used for loose scan. More precisely, the range optimizer chose to use loose index scan for queries for which the condition(s) over an index key part could not be pushed to the index together with the loose scan. As a result, loose index scan was selecting the first row in the index with a given GROUP BY prefix, and was applying the WHERE clause after that, while it should have inspected all rows with the given prefix, and apply the WHERE clause to all of them. The fix detects and skips such cases. mysql-test/r/group_min_max.result: Added test for BUG#16710. mysql-test/t/group_min_max.test: Added test for BUG#16710. sql/item.cc: Added new method [Item \| Item_field]::find_item_in_field_list_processor. sql/item.h: Added new method [Item \| Item_field]::find_item_in_field_list_processor. sql/opt_range.cc: Handle the case when there is no MIN/MAX aggregate function, and a keypart of the index being considered, that is after the GROUP BY prefix, is used in the WHERE clause and the condition where it is used cannot be pushed to the index.

unknown	0d3cf6b0fd	BUG#17265 Assertion failure in rpl_row_view01. To quote Timour review lines: The actual cause of the bug is that sql_base.cc:setup_wild() sets "select_lex->with_wild = 0" (in the end of the function) once it expands all wild-cards, and wild-card expansion is done during the prepare phase. During this phase we replace all "" with the corresponding items, which for views happen to be references to references. When we do execute, select_lex->with_wild = 0, and all "" are already replaced by the corresponding items, which in the case of views need to be dereferenced first. Fixed by refining the assert. Regression test for the bug is rpl_row_view01, as was reported. sql/item.cc: Refined asssert, suggested by Evgen, due to BUG#17265 prepared statement for select with ps-protocol does not hold the former.	20 years ago

unknown	de0c65dd4e	Fix bug #15706 find_field_in_tables() returns field from outer select If item->cached_table is set, find_field_in_tables() returns found field even if it doesn't belong to current select. Because Item_field::fix_fields doesn't expect such behaviour, reported bug occurs. Item_field::fix_fields() was modifed to detect when find_field_in_tables() can return field from outer select and process such fields accordingly. In order to ease this code which was searching and processing outed fields was moved into separate function called Item_field::fix_outer_field(). sql/item_subselect.h: Fixed bug #15706: find_field_in_tables() returns field from outer select Item_field::fix_outer_field() was marked as friend to Item_subselect class. sql/item.h: Fixed bug #15706: find_field_in_tables() returns field from outer select fix_outer_field() function is added to the Item_field class. sql/item.cc: Fixed bug #15706: find_field_in_tables() returns field from outer select Item_ref::fix_fields() and Item_field::fix_fields() were modifed to detect when find_field_in_tables() can return field from outer select and process such fields accordingly.
