Kentoku SHIBA	e53ef202bd	Adding direct update/delete to the server and to the partition engine. Add support for direct update and direct delete requests for spider. A direct update/delete request handles all qualified rows in a single operation rather than one row at a time. Contains Spiral patches: 006_mariadb-10.2.0.direct_update_rows.diff MDEV-7704 008_mariadb-10.2.0.partition_direct_update.diff MDEV-7706 010_mariadb-10.2.0.direct_update_rows2.diff MDEV-7708 011_mariadb-10.2.0.aggregate.diff MDEV-7709 027_mariadb-10.2.0.force_bulk_update.diff MDEV-7724 061_mariadb-10.2.0.mariadb-10.1.8.diff MDEV-12870 - The differences compared to the original patches: - Most of the parameters of the new functions are unnecessary. The unnecessary parameters have been removed. - Changed bit positions for new handler flags upon consideration of handler flags not needed by other Spiral patches and handler flags merged from MySQL. - Added info_push() (Was originally part of bulk access patch) - Didn't include code related to handler socket - Added HA_CAN_DIRECT_UPDATE_AND_DELETE Original author: Kentoku SHIBA First reviewer: Jacob Mathew Second reviewer: Michael Widenius	8 years ago
Monty	f26e14e2d8	Adding option to tell that cmp_ref handler call is expensive - In Spider, calling cmp_ref() can be very expensive. In ha_partition.cc we don't anymore sort rows according to position for the Spider engine. - Removed Spider specific call info(HA_EXTRA_STARTING_ORDERED_INDEX_SCAN) from handle_ordered_index_scan(). It's caused performance issues and does not change results for queries with ORDER BY. - The visible effect of this patch is that for some storage engines, rows may be returned in a different order if there is no ORDER BY clause. - Based in Spiral Patch 052: 052_mariadb-10.2.0.add_partition_skip_pk_sort_for_non_clustered_index MDEV-7748 - The major difference from original patch is that there is no variable to get the old behaviour. Other things: - Optimized ha_partition::cmp_ref() and cmp_part_ids() to make them simpler and faster. - Changed arguments to cmp_key_part_id() to be same as cmp_key_rowid_part_id to simplify code.

Monty	dc17ac1638	Adding support for auto_increment in the partition engine. Contains Spiral patches: 022_mariadb-10.2.0.auto_increment.diff MDEV-7720 030: 030_mariadb-10.2.0.partition_auto_inc_init.diff MDEV-7726 These patches have the following differences compared to the original patches: - Added the new #defines for the feature in spd_environ.h instead of in handler.h because these #defines are needed by Spider and are not needed by the server. - Cleaned up code related to the removed variable m_need_info_for_auto_inc . Changed variable assignment in lock_auto_increment() and unlock_auto_increment() so that the assignments are done under locks. - Added a test case. - Added test result changes resulting from a bug that was fixed by these patches.

Monty	2f09b28e0f	Adding Full Text Search support to partitions Contains Spiral patches: 007_mariadb-10.2.0.partition_fulltext.diff MDEV-7705 038_mariadb-10.2.0.partition_fulltext2.diff MDEV-7734 This commit has the following differences compared to the original patches: - Added necessary full text search cleanup at the storage engine layer that was omitted in the original patch. - Added test case. - A lot of code cleanups to make the code notable smaller. - Changed SQL code to use ha_ft_end() instead of ft_end() Original author: Kentoku SHIBA First reviewer: Jacob Mathew Second reviewer: Michael Widenius	8 years ago
Monty	da26d16dd1	Add direct aggregates Spider patches 026 (MDEV-7723), 031 (MDEV-7727) and 058 (MDEV-12532) This allows the storage engine to internally compute sum and count operations. - Enhance sum items to be able to store the sum value directly. - return_record_by_parent() is enabled in spider as HANDLER_HAS_DIRECT_AGGREGATE is defined - Added spd_environ.h to spider. This is loaded first to ensure that all MariaDB specific defines that are used by include files are properly defined. - This code is tested by the existing spider tests direct_aggregate.test and direct_aggregate_part.test and also partition.test	8 years ago
Monty	8eeb689e9f	Adding multi_range_read support to partitions Other things: - Cleanup of allocated bitmaps done in open(), which simplifies init_partition_bitmaps() - Add needed defines in ha_spider.cc to enable new spider code - Fixed some DBUG_PRINT() to be consistent with normal code - Removed end space - The changes in test cases partition_innodb, partition_range, partition_pruning etc are becasue partitions can now more exactly calculate the number of rows in a range. Contains spider patches: 014,015,023,033,035,037,040,042,044,045,049,050,051,053,059	8 years ago
Monty	d5268a610a	MDEV-7700 Spiral patch 002_mariadb-10.0.15.spider.diff, part 2 Allow partition engines to access table->s->connect_string for engines that uses HTON_CAN_READ_CONNECT_STRING_IN_PARTITION Don't reset table->s->connect_string in ha_partition::open	9 years ago
Monty	7abe11499a	MDEV 7701 extra() calls for VP engine Added Spider patches: 003_mariadb-10.0.15.vp.diff 060_mariadb-10.2.0.partition_reset_top_table_fields.diff - Support HA_EXTRA_ADD_CHILDREN_LIST,HA_EXTRA_ATTACH_CHILDREN, HA_EXTRA_IS_ATTACHED_CHILDREN and HA_EXTRA_DETACH_CHILDREN in partition handler for handlers that has HA_CAN_MULTISTEPL_MERGE flag - Added HA_CAN_MULTISTEPL_MERGE to MERGE handler. - Added handler::get_child_handlers() - Change m_num_lock to contain total number of locks. This was needed as we now adjust number of locks when extra(HA_EXTRA_ATTACH_CHILDREN) is called.	9 years ago
Monty	c57e1bf5e6	Added spider patches for adding HANDLER support for the partition engine 013_mariadb-10.0.15.vp_handler.diff 034_mariadb-10.0.15.vp_handler2.diff 005_mariadb-10.0.15.hs.diff 041_mariadb-10.0.15.vp_handler2.diff + Fixes from Kentoku + Added handler/suite.pm and handler/suite.opt to be able to run test cases in spider/handler	9 years ago

Marko Mäkelä	0b89a42ffc	Remove the flag vers_update_trt THD::vers_update_trt, trx_t::vers_update_trt, trx_savept_t::vers_update_trt: Remove. Instead, determine from trx_t::mod_tables whether versioned columns were affected by the transaction. handlerton::prepare_commit_versioned: Replaces vers_get_trt_data. Return the transaction start ID and also the commit ID, in case the transaction modified any system-versioned columns (0 if not). TR_table::store_data(): Remove (merge with update() below). TR_table::update(): Add the parameters start_id, end_id. ha_commit_trans(): Remove a condition on SQLCOM_ALTER_TABLE. If we need something special for ALTER TABLE...ALGORITHM=INPLACE, that can be done inside InnoDB by modifying trx_t::mod_tables. innodb_prepare_commit_versioned(): Renamed from innodb_get_trt_data(). Check trx_t::mod_tables to see if any changes to versioned columns are present. trx_mod_table_time_t: A pair of logical timestamps, replacing the undo_no_t in trx_mod_tables_t. Keep track of not only the first modification to a persistent table in each transaction, but also the first modification of a versioned column in a table. dtype_t, dict_col_t: Add the accessor is_any_versioned(), to check if the type refers to a system-versioned user or system column. upd_t::affects_versioned(): Check if an update affects a versioned column. trx_undo_report_row_operation(): If a versioned column is affected by the update, invoke trx_mod_table_time_t::set_versioned(). trx_rollback_to_savepoint_low(): If all changes to versioned columns were rolled back, invoke trx_mod_table_time_t::rollback_versioned(), so that trx_mod_table_time_t::is_versioned() will no longer hold.	8 years ago

Alexander Barkov	5d3ed9acdd	(Part#2) MDEV-13049 Querying INFORMATION_SCHEMA becomes slow in MariaDB 10.1 This is a 10.3 specific part of MDEV-13049. It disables automatic sorting for "SELECT .. FROM INFORMATION_SCHEMA.{SCHEMATA\|TABLES}" and adjusts the affected tests accordingly.	8 years ago
Vladislav Vaintroub	7354dc6773	MDEV-13384 - misc Windows warnings fixed	8 years ago
Marko Mäkelä	96f06f952d	MDEV-13847 Allow ALTER TABLE…ADD SPATIAL INDEX…ALGORITHM=INPLACE MDEV-13851 Always check table options in ALTER TABLE…ALGORITHM=INPLACE In the merge of MySQL 5.7.9 to MariaDB 10.2.2, some code was included that prevents ADD SPATIAL INDEX from being executed with ALGORITHM=INPLACE. Also, the constant ADD_SPATIAL_INDEX was introduced as an alias to ADD_INDEX. We will remove that alias now, and properly implement the same ADD SPATIAL INDEX restrictions as MySQL 5.7 does: 1. table-rebuilding operations are not allowed if SPATIAL INDEX survive it 2. ALTER TABLE…ADD SPATIAL INDEX…LOCK=NONE is not allowed ha_innobase::prepare_inplace_alter_table(): If the ALTER TABLE requires actions within InnoDB, enforce the table options (MDEV-13851). In this way, we will keep denying ADD SPATIAL INDEX for tables that use encryption (MDEV-11974), even if ALGORITHM=INPLACE is used.	8 years ago

Michael Widenius	458d5ed8aa	Lots of small cleanups - Simplified use_trans_cache() to return at once if is_transactional is set - Indentation and spelling errors fixed - Don't call signal_update() if update_binlog_end_pos() is called as the function already calls signal_update() - Removed not used function wait_for_update_bin_log(), which would cause errors if ever used. - Simplified handler::clone() by always allocating 'ref' in ha_open(). To do this I added an optional MEM_ROOT argument to ha_open() to be used when allocating 'ref' - Changed arguments to get_system_var() from LEX_CSTRING to LEX_CSTRING* - Added THD as argument to create_select_for_variable(). Changed also char* argument to LEX_CSTRING to avoid strlen() call. - Change calls to append() to use LEX_CSTRING	9 years ago
Michael Widenius	4aaa38d26e	Enusure that my_global.h is included first - Added sql/mariadb.h file that should be included first by files in sql directory, if sql_plugin.h is not used (sql_plugin.h adds SHOW variables that must be done before my_global.h is included) - Removed a lot of include my_global.h from include files - Removed include's of some files that my_global.h automatically includes - Removed duplicated include's of my_sys.h - Replaced include my_config.h with my_global.h	9 years ago

Kristian Nielsen	228479a28c	MDEV-8075: DROP TEMPORARY TABLE not marked as ddl, causing optimistic parallel replication to fail CREATE/DROP TEMPORARY TABLE are not safe to optimistically replicate in parallel with other transactions, so they need to be marked as "ddl" in the binlog. This was already done for stand-alone CREATE/DROP TEMPORARY. But temporary tables can also be created and dropped inside a BEGIN...END transaction, and such transactions were not marked as ddl. Nor was the DROP TEMPORARY TABLE statement emitted implicitly when a client connection is closed. So this patch adds such ddl mark for the missing cases. The difference to Kristian's original patch is mainly a fix in mysql_trans_commit_alter_copy_data() to remember the unsafe_rollback_flags over the temporary commit.	9 years ago

Aleksey Midenkov	448374a228	SQL, IB: (0.10) VTMD tracking [closes #124 ] IB: Fixes in logic when to do versioned or usual row updates.

RENAME TO; * DROP TABLE; * data-modifying operations (f.ex. ALTER TABLE .. ADD/DROP COLUMN).	9 years ago
Marko Mäkelä	e5980bf1b1	Remove the unnecessary method handlerton::release_temporary_latches() The sole purpose of handlerton::release_temporary_latches and its wrapper function was to release the InnoDB adaptive hash index latch (btr_search_latch). When the btr_search_latch was split into an array of latches in MySQL 5.7.8 as part of the Oracle Bug#20985298 fix, the "caching" of the latch across storage engine API calls was removed. As part of that, the function trx_search_latch_release_if_reserved() was changed to an assertion and the function trx_reserve_search_latch_if_not_reserved() was removed, and handlerton::release_temporary_latches() practically became a no-op. Note: MDEV-12121 replaced the function trx_search_latch_release_if_reserved() with the more appropriately named macro trx_assert_no_search_latch().	9 years ago
