Igor Babaev	d274e32c8c	Fixed LP bug #902356 . A memory overwrite in the function test_if_skip_sort_order() could cause a crash for some queries with subqueries.	14 years ago
Sergey Petrunya	190aa08557	BUG#902632: Crash or invalid read at st_join_table::cleanup, st_table::disable_keyread - Do a "more thorough" cleanup of SJ-Materialization join tab in JOIN_TAB::cleanup. The bug was due to the fact that JOIN_TAB::cleanup() may be called multiple times for the same tab if the join has grouping.	14 years ago
unknown	988bd172b9	The variable query_cache_strip_comments allowed in embedded server.	14 years ago
Michael Widenius	76d852d425	Automatic merge	14 years ago
Michael Widenius	b653115c8e	Fixed valgrind error when storing db_name_length in query_cache. - Changed storage to be 2 bytes instead of sizeof(size_t) (simple optimization) - Fixed bug when using query_cache_strip_comments and query that started with '(' - Fixed DBUG_PRINT() that used wrong (not initialized) variables. mysql-test/mysql-test-run.pl: Added some space to make output more readable. mysql-test/r/query_cache.result: Updated test results mysql-test/t/query_cache.test: Added test with query_cache_strip_comments sql/mysql_priv.h: Added QUERY_CACHE_DB_LENGTH_SIZE sql/sql_cache.cc: Fixed bug when using query_cache_strip_comments and query that started with '(' Store db length in 2 characters instead of size_t. Get db length from correct position (earlier we had an error when query started with ' ') Fixed DBUG_PRINT() that used wrong (not initialized) variables.	14 years ago
Sergei Golubchik	745c53ec06	5.2->5.3 merge	14 years ago
unknown	6404504d0c	Fixed bug lp:900375 The range optimizer incorrectly chose a loose scan for group by when there is a correlated WHERE condition. This range access method cannot be executed for correlated conditions also with the "range checked for each record" because generally the range access method can change for each outer record. Loose scan destructively changes the query plan and removes the GROUP operation, which will result in wrong query plans if another range access is chosen dynamically.	14 years ago
Igor Babaev	63d32c115d	Fixed LP bug #901709 . The cause of the reported assertion failure was a division of a double value by 0.	14 years ago
Igor Babaev	9b4cd1b0ae	Merge	14 years ago
Igor Babaev	fa29f18ffb	Fixed LP bug #901478 . If the duplicate elimination strategy is used for a semi-join and potentially one of the block-based join algorithms can be employed to join the inner tables of the semi-join then sorting of the head (first non-constant) table for a query with ORDER BY / GROUP BY cannot be used.	14 years ago
Igor Babaev	81d390ac86	Adjusted the results of pbxt.subselect after the latest merge 5.1->5.2->5.3.	14 years ago
Michael Widenius	24e452a208	Merge with 5.1 & fixes to IGNORE handling	14 years ago
Michael Widenius	1485874619	Rewrite IGNORE handling: - Instead of supressing all errors, only suppress safe ones like: ER_DUP_KEY, ER_BAD_NULL_ERROR, ER_SUBQUERY_NO_1_ROW, ER_ROW_IS_REFERENCED_2	14 years ago
Michael Widenius	6d4224a31c	Merge with 5.2. no_error handling for select (used by INSERT ... SELECT) still needs to be fixed, but I will do that in a separate commit	14 years ago
Igor Babaev	8a09adb3ea	Fixed LP bug #901312 . The function setup_sj_materialization_part1() forgot to set the value of TABLE::map for any materialized IN subquery. This could lead to wrong results for queries with subqueries that were converted to queries with semijoins.	14 years ago
Alexey Botchkov	fc9d34cabf	bug #901655 ST_BUFFER asserts with a coplicated shape. Coinciding nodes can appear as a result of DOUBLE inaccuracy. We should test that before we start the loop. Also the spatial relations can be calculated faster if we check MBR relations first. And we do have the shape's MBR-s now. per-file comments: sql/gcalc_slicescan.cc set_extent() method added. bug #901655 ST_BUFFER asserts with a coplicated shape. sql/gcalc_slicescan.h set_extent() method declared. bug #901655 ST_BUFFER asserts with a coplicated shape. sql/gcalc_tools.cc bug #901655 ST_BUFFER asserts with a coplicated shape. checks for equal nodes added. sql/item_geofunc.cc bug #901655 ST_BUFFER asserts with a coplicated shape. MBR for the shapes calculated, and MBR checks added before we start the heavy calculations. sql/spatial.h bug #901655 ST_BUFFER asserts with a coplicated shape. MBR::buffer() method implemented.	14 years ago
unknown	314c377422	Fixed bug lp:888456 Analysis: The class member QUICK_GROUP_MIN_MAX_SELECT::seen_first_key was not reset between subquery re-executions. Thus each subsequent execution continued from the group that was reached by the previous subquery execution. As a result loose scan reached end of file much earlier, and returned empty result where it shouldn't. Solution: Reset seen_first_key before each re-execution of the loose scan.	14 years ago
Sergey Petrunya	ae480437ce	Small semi-join optimization improvement: - if we're considering FirstMatch access with one inner table, and @@optimizer_switch has semijoin_with_cache flag, calculate costs as if we used join cache (because we will be able to do so)	14 years ago
Sergey Petrunya	8e96081764	Merge fix for BUG#868908	14 years ago
Sergey Petrunya	49ecc88069	BUG#901032: Wrong result for MIN/MAX on an indexed column with materialization and semijoin - opt_sum_query() should not assume that join tables from sj-materialization have known numbers of rows.	14 years ago
Sergey Petrunya	cdd1197060	Remove garbage assignments causing failures on Windows	14 years ago
Sergey Petrunya	a1b4eadf89	BUG#868908: Crash in check_simple_equality() with semijoin + materialization + prepared statement - Part2: safety and code cleanup	14 years ago
Igor Babaev	7414a0b6d6	Fixed LP bug #900469 . The execution plan cannot use sorting on the first table from the sequence of the joined tables if it plans to employ the block-based hash join algorithm.	14 years ago
Sergey Petrunya	8e25dcfcd7	BUG#868908: Crash in check_simple_equality() with semijoin + materialization + prepared statement - Part 1 of the fix: for semi-join merged subqueries, calling child_join->optimize() until we're done with all PS-lifetime optimizations in the parent.	14 years ago
Igor Babaev	b4c9fa321d	Fixed LP bug #899509 . The optimizer must ignore any possible hash join key when looking for the query execution plan with join_cache_level set to 0.	14 years ago

Sergey Petrunya	136408b1cf	Bug #899962 : materialized subquery with join_cache_level=3 - Make create_tmp_table() set KEY_PART_INFO attributes for the keys it creates. This wasn't needed before but is needed now, when temp. tables that are results of SJ-Materialization are being used for joins. This particular bug depended on HA_VAR_LENGTH_PART being set, but also added code to set HA_BLOB_PART and HA_NULL_PART when appropriate.	14 years ago
Igor Babaev	7d1f41265c	Fixed LP bug #899777 . KEYUSE elements for a possible hash join key are not sorted by field numbers of the second table T of the hash join operation. Besides some of these KEYUSE elements cannot be used to build any key as their key expressions depend on the tables that are planned to be accessed after the table T. The code before the patch did not take this into account and, as a result, execition of a query the employing block-based hash join algorithm could cause a crash or return a wrong result set.	14 years ago
Sergey Petrunya	a85454def8	Update test result missed in the previous cset	14 years ago
Sergey Petrunya	255fd6c929	Make subquery Materialization, as well as semi-join Materialization be shown in EXPLAIN as select_type==MATERIALIZED. Before, we had select_type==SUBQUERY and it was difficult to tell materialized subqueries from uncorrelated scalar-context subqueries.	14 years ago
Igor Babaev	b5a05df61e	Fixed LP bug #899696 . If has been decided that the first match strategy is to be used to join table T from a semi-join nest while no buffer can be employed to join this table then no join buffer can be used to join any table in the join sequence between the first one belonging to the semi-join nest and table T.	14 years ago
Sergei Golubchik	1f3e540385	updated the version in configure	14 years ago
Michael Widenius	3e2cb35e11	Added handler and temporary table usage to mytop Fixed prompt on reconnect in mysql client client/mysql.cc: Free server_version for reconnect.

Vladislav Vaintroub	1054de8699	Fix intermittently failing variables-notembedded test case. After sending packet that is too large, clienrt can get either an error packet with ER_NET_PACKET_TOO_LARGE, or a socket error. Both cases are valid, since the server does not ensure reply was fully read by client, before shutting down and closing the socket.	14 years ago
