Sergei Golubchik	d019af402c	misc after-merge changes: * remove new InnoDB-specific ER_ and HA_ERR_ codes * renamed few old ER_ and HA_ERR_ error messages to be less MyISAM-specific * remove duplicate enum definitions (durability_properties, icp_result) * move new mysql-test include files to their owner suite * rename xtradb.rdiff files to -disabled remove mistakenly committed helper perl module * remove long obsolete handler::ha_statistic_increment() method * restore the standard C xid_t structure to not have setters and getters * remove xid_t::reset that was cleaning too much * move MySQL-5.7 ER_ codes where they belong * fir innodb to include service_wsrep.h not internal wsrep headers * update tests and results	9 years ago
Jan Lindström	2e814d4702	Merge InnoDB 5.7 from mysql-5.7.9. Contains also MDEV-10547: Test multi_update_innodb fails with InnoDB 5.7 The failure happened because 5.7 has changed the signature of the bool handler::primary_key_is_clustered() const virtual function ("const" was added). InnoDB was using the old signature which caused the function not to be used. MDEV-10550: Parallel replication lock waits/deadlock handling does not work with InnoDB 5.7 Fixed mutexing problem on lock_trx_handle_wait. Note that rpl_parallel and rpl_optimistic_parallel tests still fail. MDEV-10156 : Group commit tests fail on 10.2 InnoDB (branch bb-10.2-jan) Reason: incorrect merge MDEV-10550: Parallel replication can't sync with master in InnoDB 5.7 (branch bb-10.2-jan) Reason: incorrect merge	9 years ago

Michael Widenius	fb67cde237	Use default character set for expressions - Force usage of () around complex DEFAULT expressions - Give error if DEFAULT expression contains invalid characters - Don't use const_charset_conversion for stored Item_func_sysconf expressions as the result is not constaint over different executions - Fixed Item_func_user() to not store calculated value in str_value	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	10 years ago
Sergei Golubchik	4aacb20dce	fix XID comparison according to the standard, the gtrid/bqual pair must be "globally unique", so XIDs are equal if their gtrids and bquals are identical, formatID simply tells how gtrid/bqual were generated. But if formatID == -1 (it means "null") gtrid/bqual don't have any value at all. This fixes main.xa_sync failure in ./mtr main.quary_cache_debug main.xa_sync	10 years ago
Sergei Golubchik	153259874b	MDEV-9155 Enabling Defragmenting in 10.1.8 still causes OPTIMIZE TABLE to take metadatalocks take MDL_SHARED_WRITE instead of MDL_SHARED_NO_READ_WRITE for OPTIMIZE TABLE. For engines that need a stronger lock (like MyISAM), reopen the table with MDL_SHARED_NO_READ_WRITE.	10 years ago

Monty	0485328d03	Cache check_table_binlog_row_based and mark_trx_read_write Benefits: - Speeds up insert,write and delete by avoiding 1-2 function calls per write/update/delete. - Avoiding calling write_locked_table_maps() if not needed. - The inlined code is much smaller than before - Updating of table->s->cached_row_logging_check moved to when table is opened - Moved some bool values together in handler class to get better alignment.	10 years ago
Nisha Gopalakrishnan	d9c541cb1b	BUG#22037930: INSERT IGNORE FAILS TO IGNORE FOREIGN KEY CONSTRAINT. Analysis ======= INSERT and UPDATE operations using the IGNORE keyword which causes FOREIGN KEY constraint violations reports an error despite using the IGNORE keyword. Foreign key violation errors were not ignored and reported as errors instead of warnings even when IGNORE was set. Fix === Added code to ignore the foreign key violation errors and report them as warnings when the IGNORE keyword is used.	10 years ago
Nirbhay Choubey	7ec6558503	MDEV-9021: MYSQLD SEGFAULTS WHEN BUILT USING --WITH-MAX-INDEXES=128 The bitmap implementation defines two template Bitmap classes. One optimized for 64-bit (default) wide bitmaps while the other is used for all other widths. In order to optimize the computations, Bitmap<64> class has defined its own member functions for bitmap operations, the other one, however, relies on mysys' bitmap implementation (mysys/my_bitmap.c). Issue 1: In case of non 64-bit Bitmap class, intersect() wrongly reset the received bitmap while initialising a new local bitmap structure (bitmap_init() clears the bitmap buffer) thus, the received bitmap was getting cleared. Fixed by initializing the local bitmap structure by using a temporary buffer and later copying the received bitmap to the initialised bitmap structure. Issue 2: The non 64-bit Bitmap class had the Iterator missing which caused compilation failure. Also added a cmake variable to hold the MAX_INDEXES value when supplied from the command prompt. (eg. cmake .. -DMAX_INDEXES=128U). Checks have been put in place to trigger build failure if MAX_INDEXES value is greater than 128. Test modifications: * Introduced include/have_max_indexes_[64\|128].inc to facilitate skipping of tests for which the output differs with different MAX_INDEXES. * Introduced include/max_indexes.inc which would get modified by cmake to reflect the MAX_INDEXES value used to build the server. This file simply sets an mtr variable '$max_indexes' to show the MAX_INDEXES value, which will then be consumed by the above introduced include file. * Some tests (portions), dependent on MAX_INDEXES value, have been moved to separate test files.	10 years ago

Monty	cf50e13fbd	MDEV-6080: Allowing storage engine to shortcut group by queries This task is to allow storage engines that can execute GROUP BY or summary queries efficiently to intercept a full query or sub query from MariaDB and deliver the result either to the client or to a temporary table for further processing. - Added code in sql_select.cc to intercept GROUP BY queries. Creation of group_by_handler is done after all optimizations to allow storage engine to benefit of an optimized WHERE clause and suggested indexes to use. - Added group by handler to sequence engine and a group_by test suite as a way to test the new interface. - Intercept EXPLAIN with a message "Storage engine handles GROUP BY" libmysqld/CMakeLists.txt: Added new group_by_handler files sql/CMakeLists.txt: Added new group_by_handler files sql/group_by_handler.cc: Implementation of group_by_handler functions sql/group_by_handler.h: Definition of group_by_handler class sql/handler.h: Added handlerton function to create a group_by_handler, if the storage engine can intercept the query. sql/item_cmpfunc.cc: Allow one to evaluate item_equal any time. sql/sql_select.cc: Added code to intercept GROUP BY queries - If all tables are from the same storage engine and the query is using sum functions, call create_group_by() to check if the storage engine can intercept the query. - If yes: - create a temporary table to hold a GROUP_BY row or result - In do_select() intercept normal query execution by instead calling the group_by_handler to get the result - Intercept EXPLAIN sql/sql_select.h: Added handling of group_by_handler Added caching of the original join tab (needed for cleanup after group_by handler) storage/sequence/mysql-test/sequence/group_by.result: Test group_by_handler interface storage/sequence/mysql-test/sequence/group_by.test: Test group_by_handler interface storage/sequence/sequence.cc: Added simple group_by_engine for handling COUNT(*) and SUM(primary_key). This was done as a test of the group_by_handler interface	10 years ago
Nirbhay Choubey	0abde01f5e	MDEV-8240 : Unknown option 'table_type' when using Connect Engine on MGC MariaDB Galera server's (MGC) handlerton & THD structures have some extra wsrep members as compared to MariaDB server. As a result, when plugins from packages, built along with MariaDB server like Connect & OQGraph are loaded and accessed by MGC, the objects may get initialized improperly. Fixed by moving the wsrep-additions to the end of the structure.	10 years ago
Monty	7332af49e4	- Renaming variables so that they don't shadow others (After this patch one can compile with -Wshadow and get much fewer warnings) - Changed ER(ER_...) to ER_THD(thd, ER_...) when thd was known or if there was many calls to current_thd in the same function. - Changed ER(ER_..) to ER_THD_OR_DEFAULT(current_thd, ER...) in some places where current_thd is not necessary defined. - Removing calls to current_thd when we have access to thd Part of this is optimization (not calling current_thd when not needed), but part is bug fixing for error condition when current_thd is not defined (For example on startup and end of mysqld) Notable renames done as otherwise a lot of functions would have to be changed: - In JOIN structure renamed: examined_rows -> join_examined_rows record_count -> join_record_count - In Field, renamed new_field() to make_new_field() Other things: - Added DBUG_ASSERT(thd == tmp_thd) in Item_singlerow_subselect() just to be safe. - Removed old 'tab' prefix in JOIN_TAB::save_explain_data() and use members directly - Added 'thd' as argument to a few functions to avoid calling current_thd.	11 years ago

Praveenkumar Hulakund	cf4231a7f9	Bug#18790730 - CROSS-DATABASE FOREIGN KEY WITHOUT PERMISSIONS CHECK. Analysis: ---------- Issue here is, while creating or altering the InnoDB table, if the foreign key defined on the table references a parent table on which the user has no access privileges then the table is created without reporting any error. Currently the privilege level REFERENCES_ACL is unused and is not used for access evaluation while creating the table with a foreign key constraint or adding the foreign key constraint to a table. But when no privileges are granted to user then also access evaluation on parent table is ignored. Fix: --------- For DMLs, irrelevant of the fact, support does not want any changes to avoid permission checks on every operation. So, as a fix, added a function "check_fk_parent_table_access" to check whether any of the SELECT_ACL, INSERT_ACL, UDPATE_ACL, DELETE_ACL or REFERENCE_ACL privileges are granted for user at table level. If none of them is granted then error is reported. This function is called during the table creation and alter operation.	11 years ago
