In practice this means that handlerton is now created by the server and is passed to the engine. Plugin startups can now also control how plugins are inited (and can optionally pass values). Bit more flexibility to those who want to write plugin interfaces to the database. include/mysql/plugin.h: Optional to pass parameter now to init and deinit functions sql/ha_ndbcluster.cc: Cleanup, handlerton is now a pointer. sql/ha_ndbcluster_binlog.cc: Cleanup (handlerton is now a pointer) sql/ha_ndbcluster_binlog.h: Cleanup (handlerton is now a pointer) sql/ha_partition.cc: Cleaned up handlerton change sql/handler.cc: Cheanup of handlerton change sql/item_sum.cc: Cleanedup of handlerton change sql/log.cc: Cleanup of handlerton change sql/mysql_priv.h: Reverted patch for variables (what would have happen previously if a have_ would have been called that was dynamically loaded? boom!) sql/mysqld.cc: Cleanup of handlerton changes and reverted have variable patch sql/partition_info.cc: Cleanup of handlerton (we need to clean this up a bit more). sql/set_var.cc: Cleanup related to handlerton changes sql/sql_cache.cc: Handlerton changes cleanup sql/sql_insert.cc: Handlerton changes cleanup. sql/sql_partition.cc: Handlerton cleanup changes sql/sql_plugin.cc: Handlerton changes. init() can now be controlled by a plugin specific startup.

1003: Incorrect table name in multi-table DELETE the set of tables to delete from actually references then tables in the other list, e.g: DELETE alias_of_t1 FROM t1 alias_of_t1 WHERE .... is a valid statement. So we must turn off table name syntactical validity check for alias_of_t1 because it's not a table name (even if it looks like one). In order to do that we add a special flag (TL_OPTION_ALIAS) to disable the name checking for the aliases in multi-table DELETE. mysql-test/r/delete.result: Bug #21392: multi-table delete with alias table name fails with 1003: Incorrect table name - test case mysql-test/t/delete.test: Bug #21392: multi-table delete with alias table name fails with 1003: Incorrect table name - test case sql/mysql_priv.h: Bug #21392: multi-table delete with alias table name fails with 1003: Incorrect table name - add a special flag to disable the name checking for the aliases in multi-table DELETE sql/sql_parse.cc: Bug #21392: multi-table delete with alias table name fails with 1003: Incorrect table name - add a special flag to disable the name checking for the aliases in multi-table DELETE sql/sql_yacc.yy: Bug #21392: multi-table delete with alias table name fails with 1003: Incorrect table name - add a special flag to disable the name checking for the aliases in multi-table DELETE

User name (host name) has limit on length. The server code relies on these limits when storing the names. The problem was that sometimes these limits were not checked properly, so that could lead to buffer overflow. The fix is to check length of user/host name in parser and if string is too long, throw an error. mysql-test/r/grant.result: Updated result file. mysql-test/r/sp.result: Updated result file. mysql-test/r/trigger.result: Updated result file. mysql-test/r/view.result: Updated result file. mysql-test/t/grant.test: Added test for BUG#16899. mysql-test/t/sp.test: Added test for BUG#16899. mysql-test/t/trigger.test: Added test for BUG#16899. mysql-test/t/view.test: Added test for BUG#16899. sql/mysql_priv.h: Added prototype for new function. sql/sql_acl.cc: Remove outdated checks. sql/sql_parse.cc: Add a new function for checking string length. sql/share/errmsg.txt: Added new resources. sql/sql_yacc.yy: Check length of user/host name.

SELECT right instead of INSERT right was required for an insert into to a view. This wrong behaviour appeared after the fix for bug #20989. Its intention was to ask only SELECT right for all tables except the very first for a complex INSERT query. But that patch has done it in a wrong way and lead to asking a wrong access right for an insert into a view. The setup_tables_and_check_access() function now accepts two want_access parameters. One will be used for the first table and the second for other tables. mysql-test/t/view.test: Added a test case for bug#21261: Wrong access rights was required for an insert into a view mysql-test/r/view.result: Added a test case for bug#21261: Wrong access rights was required for an insert into a view sql/sql_update.cc: Fixed bug#21261: Wrong access rights was required for an insert into a view Modified to use updated setup_tables_and_check_access() function. sql/sql_select.cc: Fixed bug#21261: Wrong access rights was required for an insert into a view Modified to use updated setup_tables_and_check_access() function. sql/sql_load.cc: Fixed bug#21261: Wrong access rights was required for an insert into a view Modified to use updated setup_tables_and_check_access() function. sql/sql_insert.cc: Fixed bug#21261: Wrong access rights was required for an insert into a view Modified to use updated setup_tables_and_check_access() function. sql/sql_delete.cc: Fixed bug#21261: Wrong access rights was required for an insert into a view Modified to use updated setup_tables_and_check_access() function. sql/sql_base.cc: Fixed bug#21261: Wrong access rights was required for an insert into a view The setup_tables_and_check_access() function now accepts two want_access parameters.

Continued implementation of WL#1324 (table name to filename encoding) The intermediate (not temporary) files of the new table during ALTER TABLE was visible for SHOW TABLES. These intermediate files are copies of the original table with the changes done by ALTER TABLE. After all the data is copied over from the original table, these files are renamed to the original tables file names. So they are not temporary files. They persist after ALTER TABLE, but just with another name. In 5.0 the intermediate files are invisible for SHOW TABLES because all file names beginning with "#sql" were suppressed. This failed since 5.1.6 because even temporary table names were converted when making file names from them. The prefix became converted to "@0023sql". Converting the prefix during SHOW TABLES would suppress the listing of user tables that start with "#sql". The solution of the problem is to continue the implementation of the table name to file name conversion feature. One requirement is to suppress the conversion for temporary table names. This change is straightforward for real temporary tables as there is a function that creates temporary file names. But the generated path names are located in TMPDIR and have no relation to the internal table name. This cannot be used for ALTER TABLE. Its intermediate files need to be in the same directory as the old table files. And it is necessary to be able to deduce the same path from the same table name repeatedly. Consequently the intermediate table files must be handled like normal tables. Their internal names shall start with tmp_file_prefix (#sql) and they shall not be converted like normal table names. I added a flags parameter to all relevant functions that are called from ALTER TABLE. It is used to suppress the conversion for the intermediate table files. The outcome is that the suppression of #sql in SHOW TABLES works again. It does not suppress user tables as these are converted to @0023sql on file level. This patch does also fix ALTER TABLE ... RENAME, which could not rename a table with non-ASCII characters in its name. It does also fix the problem that a user could create a table like `#sql-xxxx-yyyy`, where xxxx is mysqld's pid and yyyy is the thread ID of some other thread, which prevented this thread from running ALTER TABLE. Some of the above problems are mentioned in Bug 1405, which can be closed with this patch. This patch does also contain some minor fixes for other forgotten conversions. Still known problems are reported as bugs 21370, 21373, and 21387. mysql-test/r/alter_table.result: Bug#18775 - Temporary table from alter table visible to other threads Continued implementation of WL#1324 (table name to filename encoding) Added test results. mysql-test/r/backup.result: Bug#18775 - Temporary table from alter table visible to other threads Continued implementation of WL#1324 (table name to filename encoding) Added test results. mysql-test/r/repair.result: Bug#18775 - Temporary table from alter table visible to other threads Continued implementation of WL#1324 (table name to filename encoding) Added test results. mysql-test/t/alter_table.test: Bug#18775 - Temporary table from alter table visible to other threads Continued implementation of WL#1324 (table name to filename encoding) Added test cases. mysql-test/t/backup.test: Bug#18775 - Temporary table from alter table visible to other threads Continued implementation of WL#1324 (table name to filename encoding) Added test cases. mysql-test/t/repair.test: Bug#18775 - Temporary table from alter table visible to other threads Continued implementation of WL#1324 (table name to filename encoding) Added a test case. sql/ha_myisam.cc: Bug#18775 - Temporary table from alter table visible to other threads Continued implementation of WL#1324 (table name to filename encoding) Added missing table name mapping calls to backup() and restore(). sql/ha_myisammrg.cc: Bug#18775 - Temporary table from alter table visible to other threads Continued implementation of WL#1324 (table name to filename encoding) Added an zero argument for the new 'flags' parameter. sql/ha_ndbcluster.cc: Bug#18775 - Temporary table from alter table visible to other threads Continued implementation of WL#1324 (table name to filename encoding) Added an zero argument for the new 'flags' parameter. sql/ha_ndbcluster_binlog.cc: Bug#18775 - Temporary table from alter table visible to other threads Continued implementation of WL#1324 (table name to filename encoding) Added an zero argument for the new 'flags' parameter. sql/ha_ndbcluster_binlog.h: Bug#18775 - Temporary table from alter table visible to other threads Continued implementation of WL#1324 (table name to filename encoding) Removed unnecessary check for wrong temp file prefix. sql/mysql_priv.h: Bug#18775 - Temporary table from alter table visible to other threads Continued implementation of WL#1324 (table name to filename encoding) Extended quick_rm_table(), mysql_rename_table(), and build_table_filename() by an flags argument, which can indicate temporary table names that should not be converted.

'conc_sys' test Concurrent execution of SELECT involing at least two INFORMATION_SCHEMA tables, DROP DATABASE statement and DROP TABLE statement could have resulted in stalled connection for this SELECT statement. The problem was that for the first query of a join there was a race between select from I_S.TABLES and DROP DATABASE, and the error (no such database) was prepared to be send to the client, but the join processing was continued. On second query to I_S.COLUMNS there was a race with DROP TABLE, but this error (no such table) was downgraded to warning, and thd->net.report_error was reset. And so neither result nor error was sent to the client. The solution is to stop join processing once it is clear we are going to report a error, and also to downgrade to warnings file system errors like 'no such database' (unless we are in the 'SHOW' command), because I_S is designed not to use locks and the query to I_S should not abort if something is dropped in the middle. No test case is provided since this bug is a result of a race, and is timing dependant. But we test that plain SHOW TABLES and SHOW COLUMNS give a error if there is no such database or a table respectively. mysql-test/r/show_check.result: Add result for the test that SHOW TABLES and SHOW COLUMNS give a error if there is no such database or a table respectively. mysql-test/t/show_check.test: Add test case that SHOW TABLES and SHOW COLUMNS give a error if there is no such database or a table respectively. sql/mysql_priv.h: Remove prototype of mysql_find_files(), which is made static under find_files() name. sql/sql_show.cc: Rename mysql_find_files() to find_files() and make it static. Return FIND_FILES_OK for success, FIND_FILES_OOM for out of memory, and FIND_FILES_DIR for directory reading error. Downgrade error to warning in get_all_tables() if it is a FIND_FILES_DIR error, and we are not in the 'SHOW' command. Once 'result' is set to 1 in get_schema_tables_result(), there's no need in continuing iterations, as we are about to return a error.

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

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).

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.

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".

Addendum fixes after changing the condition variable for the global read lock. The stress test suite revealed some deadlocks. Some were related to the new condition variable (COND_global_read_lock) and some were general problems with the global read lock. It is now necessary to signal COND_global_read_lock whenever COND_refresh is signalled. We need to wait for the release of a global read lock if one is set before every operation that requires a write lock. But we must not wait if we have locked tables by LOCK TABLES. After setting a global read lock a thread waits until all write locks are released. mysql-test/r/lock_multi.result: Bug#16986 - Deadlock condition with MyISAM tables Addendum fixes after changing the condition variable for the global read lock.

schemas The function check_one_table_access() called to check access to tables in SELECT/INSERT/UPDATE was doing additional checks/modifications that don't hold in the context of setup_tables_and_check_access(). That's why the check_one_table() was split into two : the functionality needed by setup_tables_and_check_access() into check_single_table_access() and the rest of the functionality stays in check_one_table_access() that is made to call the new check_single_table_access() function. mysql-test/r/view_grant.result: Bug #20482: failure on Create join view with sources views/tables in different schemas - test suite for the bug mysql-test/t/view_grant.test: Bug #20482: failure on Create join view with sources views/tables in different schemas - test suite for the bug sql/mysql_priv.h: Bug #20482: failure on Create join view with sources views/tables in different schemas - check_one_table_access split into 2 sql/sql_base.cc: Bug #20482: failure on Create join view with sources views/tables in different schemas - the new sub-function called sql/sql_parse.cc: Bug #20482: failure on Create join view with sources views/tables in different schemas - check_one_table_access() split into two : check_single_table_access() to actually check access to the table(ro) and check_one_table_access() that calls check_single_table_access() and checks also the tables belonging to sub selects or implicitly opened tables.

SHOW STATUS does not anymore change local status variables (except com_show_status). Global status variables are still updated. SHOW STATUS are not anymore put in slow query log because of no index usage. Implemntation done by removing orig_sql_command and moving logic of SHOW STATUS to mysql_excute_command() This simplifies code and allows us to remove some if statements all over the code. Upgraded uc_update_queries[] to sql_command_flags and added more bitmaps to better categorize commands. This allowed some overall simplifaction when testing sql_command. Fixes bugs: Bug#10210: running SHOW STATUS increments counters it shouldn't Bug#19764: SHOW commands end up in the slow log as table scans mysql-test/r/grant_cache.result: Fixed results after SHOW STATUS doesn't anymore affect status variables mysql-test/r/information_schema.result: Added extra test to cover more code mysql-test/r/query_cache.result: Remove resuts from previous tests mysql-test/r/status.result: Added more tests for testing of last_query_cost and how SHOW STATUS affects status variables. (Bug#10210) mysql-test/r/temp_table.result: Fixed results after SHOW STATUS doesn't anymore affect status variables mysql-test/r/union.result: Fixed results after SHOW STATUS is not logged to slow query log (Bug#19764) mysql-test/t/events_microsec.test: Disable warnings at init mysql-test/t/information_schema.test: Added extra test to cover more code mysql-test/t/query_cache.test: Remove resuts from previous tests mysql-test/t/status.test: Added more tests for testing of last_query_cost and how SHOW STATUS affects status variables. (Bug #10210) sql/mysql_priv.h: Added 'sql_command_flags' sql/sql_class.cc: New function add_diff_to_status(), used to update global status variables when using SHOW STATUS sql/sql_class.h: New function 'fill_information_schema_tables()' (One could not anymore use fill_derived_tables() for this as only_view_structures() is not relevant for information schema tables) Added defines for bit flags in sql_command_flags[] sql/sql_lex.cc: Remove orig_sql_command sql/sql_lex.h: Remove orig_sql_command sql/sql_parse.cc: Rename uc_update_queries -> sql_command_flags. Enhanced 'sql_command_flags' to better classify SQL commands uc_update_queries[] != 0 is changed to (sql_command_flags[] & CF_CHANGES_DATA) lex->orig_sql_command == SQLCOM_END is changed to (sql_command_flags[lex->sql_command] & CF_STATUS_COMMAND) == 0) Simplify incrementing of thd->status_var.com_stat[] as we don't have to do special handling for SHOW commands. Split SQLCOM_SELECT handling in mysql_execute_command() to a separate function. Added special handling of SHOW STATUS commands in mysql_execute_command() and call common SQLCOM_SELECT handling. These changes allows us to easily fix that we save and restore status variables during execution of a SHOW STATUS command. Don't log SHOW STATUS commands to slow query log. This fixes Bug#10210 and Bug#19764 without adding additional 'if' code. (The new code is faster than the original as we now have fewer if's than before) sql/sql_prepare.cc: Clean up prepare-check handling of SQLCOM commands by using sql_command_flags[] This simplifes code and ensures that code works even if someone forgets to put a new status commands into the switch statement. sql/sql_select.cc: Remove special handling of SHOW STATUS. (This is now done in SQLCOM_SHOW_STATUS part in mysql_execute_command()) sql/sql_show.cc: Remove orig_sql_command Only change sql_command during 'open_normal_and_derived_tables()' (for views) and not for the full duration of generating data. Changed 'show status' to use thd->initial_status_var to ensure that the current statement is not affecting the to-be-used values. Use thd->fill_information_schema_tables() instead of 'thd->fill_derived_tables()' as the later wrongly checks the value of sql_command. sql/sql_yacc.yy: Remove usage of orig_sql_command. One side effect of this is that we need to test for cursors if the current command is a SELECT or a SHOW command. sql/structs.h: Updated comment

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 ... 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 ... SELECT in a mixed environment (This found some bugs that Mats is going to fix shortly) mysql-test/r/binlog_stm_mix_innodb_myisam.result: Added testing of CREATE ...

SET ... mysql-test/t/multi_update.test: Test multi updates and deletes using primary key and without mysql-test/t/view_grant.test: Drop used views mysql-test/valgrind.supp: Added supression of not needed warnings when printing stack trace mysys/base64.c: Include my_global.h first mysys/my_bitmap.c: Added bitmap_is_overlapping(), bitmap_test_and_clear() and bitmap_copy() Changed logic of bitmap handling to be a bit more efficent (Did this together with Mikael Ronström) Now the 'extra, not used bits' in the bitmap are assumed to have a 'random value' and the bitmap functions are free to change them whenever needed. 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'

mysql-test/r/partition.result: New test case sql/lock.cc: Added new flag to lock_table_name to ensure we get proper name lock even when we already have lock on table. sql/mysql_priv.h: Added new flag to lock_table_name to ensure we get proper name lock even when we already have lock on table. Added table_list to ALTER_PARTITION_PARAM_TYPE and changed some const char * to char* sql/sql_base.cc: Added new flag to lock_table_name to ensure we get proper name lock even when we already have lock on table. Added table_list to ALTER_PARTITION_PARAM_TYPE and changed some const char * to char* sql/sql_partition.cc: New methods to 1) Get a name lock even when we already have one 2) New method that unlocks table and closes the handlers. 3) Release name lock Integrated those new methods to ensure that handlers are unlocked and closed when drop or rename is called on them. There is still some work to update the comments to reflect the last changes.

The check for view security was lacking several points : 1. Check with the right set of permissions : for each table ref that participates in a view there were the right credentials to use in it's security_ctx member, but these weren't used for checking the credentials. This makes hard enforcing the SQL SECURITY DEFINER|INVOKER property consistently. 2. Because of the above the security checking for views was just ruled out in explicit ways in several places. 3. The security was checked only for the columns of the tables that are brought into the query from a view. So if there is no column reference outside of the view definition it was not detecting the lack of access to the tables in the view in SQL SECURITY INVOKER mode. The fix below tries to fix the above 3 points. mysql-test/r/grant.result: removed nondeterminism (unspecified order) in some test output mysql-test/r/view_grant.result: Somewhat extended test case for the bug and similar queries. mysql-test/t/grant.test: removed nondeterminism (unspecified order) in some test output mysql-test/t/view_grant.test: Somewhat extended test case for the bug and similar queries. sql/mysql_priv.h: A wrapper for setup_tables that also checks access to the tables sql/sql_acl.cc: removed artificial security check stop and used the table ref's credentials. sql/sql_base.cc: a wrapper for setup_tables to check access to the tables sql/sql_delete.cc: wrapper called. sql/sql_insert.cc: wrapper called sql/sql_load.cc: wrapper called sql/sql_parse.cc: wrapper called and artificial check stop removed sql/sql_select.cc: wrapper called sql/sql_update.cc: wrapper called sql/table.cc: Mask table access to the view error as well.
