Sergei Golubchik	cd51c7fb60	move away from TIMESTAMP_DNUN_FIELD/TIMESTAMP_DN_FIELD code use the new approach with Field->default_value expressions. But keep the old TIMESTAMP_UN_FIELD for ON UPDATE NOW().	9 years ago
Sergei Golubchik	73a220aac3	session-state dependent functions in DEFAULT/CHECK/vcols * revert part of the `db7edfe` that moved calculations from fix_fields to val_str for Item_func_sysconst and descendants * mark session state dependent functions in check_vcol_func_processor() * re-run fix_fields for all such functions for every statement * fix CURRENT_USER/CURRENT_ROLE not to use Name_resolution_context (that is allocated on the stack in unpack_vcol_info_from_frm()) Note that NOW(), CURDATE(), etc use lazy initialization and do not force fix_fields to be re-run. The rule is: * lazy initialization is not allowed, if it changes metadata (so, e.g. DAYNAME() cannot use it) * lazy initialization is preferrable if it has side effects (e.g. NOW() sets thd->time_zone_used=1, so it's better to do it when the value of NOW is actually needed, not when NOW is simply prepared)	9 years ago

Michael Widenius	2fe8dd0f90	various cleanups	10 years ago
Michael Widenius	db7edfed17	MDEV-7563 Support CHECK constraint as in (or close to) SQL Standard MDEV-10134 Add full support for DEFAULT - Added support for using tables with MySQL 5.7 virtual fields, including MySQL 5.7 syntax - Better error messages also for old cases - CREATE ... SELECT now also updates timestamp columns - Blob can now have default values - Added new system variable "check_constraint_checks", to turn of CHECK constraint checking if needed. - Removed some engine independent tests in suite vcol to only test myisam - Moved some tests from 'include' to 't'. Should some day be done for all tests. - FRM version increased to 11 if one uses virtual fields or constraints - Changed to use a bitmap to check if a field has got a value, instead of setting HAS_EXPLICIT_VALUE bit in field flags - Expressions can now be up to 65K in total - Ensure we are not refering to uninitialized fields when handling virtual fields or defaults - Changed check_vcol_func_processor() to return a bitmap of used types - Had to change some functions that calculated cached value in fix_fields to do this in val() or getdate() instead. - store_now_in_TIME() now takes a THD argument - fill_record() now updates default values - Add a lookahead for NOT NULL, to be able to handle DEFAULT 1+1 NOT NULL - Automatically generate a name for constraints that doesn't have a name - Added support for ALTER TABLE DROP CONSTRAINT - Ensure that partition functions register virtual fields used. This fixes some bugs when using virtual fields in a partitioning function	9 years ago
Igor Babaev	9606525666	Simplified the code that fills recursive tables.	9 years ago
Nirbhay Choubey	7305be2f7e	MDEV-5535: Cannot reopen temporary table mysqld maintains a list of TABLE objects for all temporary tables created within a session in THD. Here each table is represented by a TABLE object. A query referencing a particular temporary table for more than once, however, failed with ER_CANT_REOPEN_TABLE error because a TABLE_SHARE was allocate together with the TABLE, so temporary tables always had only one TABLE per TABLE_SHARE. This patch lift this restriction by separating TABLE and TABLE_SHARE objects and storing TABLE_SHAREs for temporary tables in a list in THD, and TABLEs in a list within their respective TABLE_SHAREs.	10 years ago
Sergey Vojtovich	7ecb304996	Code cleanups - unused TABLE_SHARE::deleting and TABLE_LIST::deleting flags were removed - kill_delayed_threads_for_table() and intern_close_table() are now private methods of table cache - removed free_share flag of closefrm(): it was never used for temporary tables and was rarely useful for regular tables	10 years ago

Igor Babaev	0a6e6d705b	Fixed numerous problems for mutually recursive CTE. Actually mutually recursive CTE were not functional. Now the code for mutually recursive CTE looks like functional, but still needs re-writing. Added many new test cases for mutually recursive CTE.	10 years ago

Monty	293cb04959	MDEV-9621 INSERT DELAYED fails on insert for tables with many columns This fix also fixes a connection hang when trying to do INSERT DELAYED to a crashed table. Added crash_mysqld.inc to allow easy crash+restart of mysqld	10 years ago
Monty	260dd476b0	Removed TABLE->sort to make it possible to have multiple active calls to filesort and init_read_record() for the same table. This will simplify code for WINDOW FUNCTIONS (MDEV-6115) - Filesort_info renamed to SORT_INFO and moved to filesort.h - filesort now returns SORT_INFO - init_read_record() now takes a SORT_INFO parameter. - unique declaration is moved to uniques.h - subselect caching of buffers is now more explicit than before - filesort_buffer is now reusable even if rec_length has changed. - filsort_free_buffers() and free_io_cache() calls are removed - Remove one malloc() when using get_addon_fields() Other things: - Added --debug-assert-on-not-freed-memory option to make it easier to debug some not-freed-memory issues.	10 years ago

Oleksandr Byelkin	6c414fcf89	MDEV-5542: GROUP_CONCAT truncate output to 65.536 chars when using DISTINCT or ORDER BY port of mysql fix WL#6098	10 years ago
Igor Babaev	2cfc450bf7	This is the consolidated patch for mdev-8646: "Re-factor the code for post-join operations". The patch mainly contains the code ported from mysql-5.6 and created for two essential architectural changes: 1. WL#5558: Resolve ORDER BY execution method at the optimization stage 2. WL#6071: Inline tmp tables into the nested loops algorithm The first task was implemented for mysql-5.6 by Ole John Aske. It allows to make all decisions on ORDER BY operation at the optimization stage. The second task implemented for mysql-5.6 by Evgeny Potemkin adds JOIN_TAB nodes for post-join operations that require temporary tables. It allows to execute these operations within the nested loops algorithm that used to be used before this task only for join queries. Besides these task moves all planning on the execution of these operations from the execution phase to the optimization phase. Some other re-factoring changes of mysql-5.6 were pulled in, mainly because it was easier to pull them in than roll them back. In particular all changes concerning Ref_ptr_array were incorporated. The port required some changes in the MariaDB code that concerned the functionality of EXPLAIN and ANALYZE. This was done mainly by Sergey Petrunia.	10 years ago
Sergei Golubchik	0686c34d22	MDEV-8605 MariaDB not use DEFAULT value even when inserted NULL for NOT NULLABLE column NOT NULL constraint must be checked after the BEFORE triggers. That is for INSERT and UPDATE statements even NOT NULL fields must be able to store a NULL temporarily at least while BEFORE INSERT/UPDATE triggers are running.	10 years ago

Monty	e3868ee072	Don't store vcol bitmaps in TABLE if table doesn't have virtual fields. (Makes TABLE a bit smaller)	10 years ago
Monty	93d1e5ce0b	table->write_set was changed if binary logging was used, which caused the changes in query execution plans. Fixed by introducing table->rpl_write_set which holds which columns should be stored in the binary log. Other things: - Removed some not needed references to read_set and write_set to make code really changing read_set and write_set easier to read (in opt_range.cc) - Added error handling of failed unpack_current_row() - Added missing call to mark_columns_needed_for_insert() for DELAYED INSERT - Removed not used functions in_read_set() and in_write_set() - In rpl_record.cc, removed not used variable error	10 years ago
Vicențiu Ciorbaru	e53ad95b73	[MDEV-6877] Added mark_columns_per_bitmap_row_image Depending on which binlog_row_image we are using, we must mark columns which to update differently both in the before image as well as the after image.	11 years ago

Vicențiu Ciorbaru	45b6edb158	MDEV-6838: Using too big key for internal temp tables This bug manifests due to wrong computation and evaluation of keyinfo->key_length. The issues were: * Using table->file->max_key_length() as an absolute value that must not be reached for a key, while it represents the maximum number of bytes possible for a table key. * Incorrectly computing the keyinfo->key_length size during KEY_PART_INFO creation. The metadata information regarding the key such the field length (for strings) was added twice.	11 years ago

ON DUPLICATE KEY UPDATE - the set of fields does change per row and in that case we reset default fields per row.	11 years ago
