Sergei Golubchik	d126993404	MDEV-4951 drop user leaves privileges It's safe to delete from HASH when traversing it backwards, but not forwards.	12 years ago
Igor Babaev	1906f1388e	Fixed bug mdev-4959. The fix for mdev-4420 was not quite correct. This patch corrects it.	12 years ago
Michael Widenius	112411b056	Fixed MySQL bug #69861 LAST_INSERT_ID is replicated incorrectly if replication filters are used mysql-test/suite/rpl/r/last_insert_id.result: Test case for last_insert_id mysql-test/suite/rpl/t/last_insert_id.cnf: Test case for last_insert_id mysql-test/suite/rpl/t/last_insert_id.test: Test case for last_insert_id sql/log_event.cc: Added DBUG_PRINT Set thd->first_successful_insert_id_in_prev_stmt_for_binlog when setting thd->first_successful_insert_id_in_prev_stmt. This is required to get last_insert_id() replicated. This is analog to how read_first_successful_insert_id_in_prev_stmt() works. sql/rpl_utility.cc: Added DBUG_PRINT	12 years ago
Igor Babaev	650d3266bb	Fixed bug mdev-4952 When in function remove_eq_conds() a sub-formula of the processed condition is replaced for another formula we should ensure that in the resulting formula AND/OR levels must alternate.	12 years ago
Igor Babaev	901737c978	Fixed bug mdev-4944. The patch to fix mdev-4418 turned out to be incorrect. At the substitution of single row tables in make_join_statistics() the used multiple equalities may change and references to the new multiple equalities must be updated. The function remove_eq_conds() takes care of it and it should be called right after the substitution of single row tables. Calling it after the call of make_join_statistics was a mistake.	12 years ago
Igor Babaev	dbc84ff96c	Fixed bug mdev-4942. Made sure that degenerate conjunctions/disjunctions are obtained from AND/OR conditions.	12 years ago
Igor Babaev	540eeebbb0	Fixed bug mdev-4420. The code of JOIN::optimize that performed substitutions for the best equal field in all ref items did not take into account that a multiple equality could contain the result of the single-value subquery if the subquery is inexpensive. This code was corrected. Also made necessary corresponding corrections in the code of make_join_select().	12 years ago
Alexander Barkov	c40de1df36	MDEV-4804 Date comparing false result	12 years ago
Sergey Petrunya	37e9714c5e	MDEV-4840: Wrong result (missing rows) on LEFT JOIN with InnoDB tables Fix two problems in table elimination code: - Before marking a "value" as bound, check if it is already bound. Marking the same value as bound twice could confuse a module that depends on this value, because Dep_module_XXX use counters to know when they become bound. - When checking whether field is part of a key, ignore "extended keys" property.	12 years ago
unknown	f8af4423b4	MDEV-4908: Assertion `((Item_cond ) cond)->functype() == ((Item_cond ) new_item)->functype()' fails on a query with IN and equal conditions, AND/OR, materialization+semijoin A new AND Item should be prepared (fix_field() call) before using.	12 years ago
Igor Babaev	99992f6ec4	Fixed a bug/typo in the patch for mdev-4355, noticed after the patch had been merged into 5.5. Corrected the result of the output from the test case for mdev 4895.	12 years ago
unknown	5fdb531d77	Fix bug MDEV-4895 Valgrind warnings (Conditional jump or move depends on uninitialised value) in Field_datetime::get_date on GREATEST(..) IS NULL Analysis: The cause of the valgrind warning was an attempt to evaluate a Field that was not yet read. The reason was that on one hand Item_func_isnotnull was marked as constant by Item_func_isnotnull::update_used_tables, and this allowed eval_const_cond() to be called. On the other hand Item_func_isnotnull::val_int() evaluated its argument as if it was not constant. Solution: The fix make sure that Item_func_isnotnull::val_int() doesn't evaluate its argument when it is constant and cannot be NULL, because the result is known in this case.	12 years ago
unknown	84a2fb4836	Backport from 10.0-base fix for tests failing when vardir has no execute permissions.	12 years ago
Igor Babaev	25c152018d	Fixed bug mdev-4418. After single row substitutions there might appear new equalities. They should be properly propagated to all AND/OR levels the WHERE condition. It's done now with an additional call of remove_eq_conds().	12 years ago
Igor Babaev	fa7f677218	Fixed bug mdev-4355. This patch almost totally revised the patch for bug mdev-4177. The latter had too many defects. In particular, it did not propagate multiple equalities formed when merging a degenerate disjunct into underlying AND formula.	12 years ago
Igor Babaev	6dd9f049ab	Fixed bug mdev-4894. This a an old legacy performance bug. When a very selective range scan existed for the second table in a join, and, at the same time, there was another range condition depending on the fields of the first table, the optimizer chose a plan with 'Range checked for each record'. This plan was extremely inefficient in comparison with the regular selective range scan. As a matter of fact the range scan chosen for each record was the same as that selective range scan. Changed the test case for bug 24776 to preserve the old output for explain.	12 years ago
Alexander Barkov	f1b4718ec8	MDEV-4652 Wrong result for CONCAT(GREATEST(TIME('00:00:01'),TIME('00:00:00'))	12 years ago
Sergei Golubchik	b718dc449b	mysql --skip-column-names flag should not affect alignment of field values, set num_flag[] unconditionally, not under "if (column_names)" http://ronaldbradford.com/blog/unexplained-trivial-mysql-behavior-2013-08-02/	12 years ago

Alexander Barkov	e6a6f653a9	MDEV-4512 Valgrind warnings in my_long10_to_str_8bit on INTERVAL and DATE_ADD with incorrect types Fixing a typo: bit AND (&) was erroneously used instead of logical AND (&&)	12 years ago

unknown	edcae48734	MDEV-4823: Server crashes in Item_func_not::fix_fields on creating a table with a virtual column using NOT fix_field() call protocol was brocken (zero pointer passed as link to item which is possible only if you are sure that there can not be Items which transforms).	13 years ago
Sergey Petrunya	04684b7709	MDEV-4817: Optimizer fails to optimize expression of the form 'FOO' IS NULL - Modify the way Item_cond::fix_fields() and Item_cond::eval_not_null_tables() calculate bitmap for Item_cond_or::not_null_tables(): if they see a "... OR inexpensive_const_false_item OR ..." then the item can be ignored. - Updated test results. There can be more warnings produced since parts of WHERE are evaluated more times.	13 years ago
unknown	66ec79fc87	Fix for MDEV-4219 A simple select query returns random data (upstream bug#68473) In the case of loose scan used as input for order by, end_send() didn't detect correctly that a loose scan was used, and didn't copy the non-aggregated fields from the temp table used for ORDER BY. The fix uses the fact that the quick select used for sorting is attached to JOIN::pre_sort_join_tab instead of JOIN::join_tab.	13 years ago

Sergey Petrunya	47c1b04079	MDEV-4778: Incorrect results from Aria/MyISAM SELECT using index with prefix length on TEXT column Backport the fix olav.sandstaa@sun.com-20101102184747-qfuntqwj021imy9r: "Fix for Bug#52660 Perf. regr. using ICP for MyISAM on range queries on an index containing TEXT" (together with further fixes in that code) into MyISAM and Aria.	13 years ago
Sergey Petrunya	9651a6f574	mdev-4173: Wrong result (extra row) with semijoin=on, joins in outer query, LEFT JOIN in the subquery Apply the patch from Patryk Pomykalski: - create_internal_tmp_table_from_heap() will now return information whether the last row that we tried to write was a duplicate row. (mysql-5.6 also has this change)	13 years ago

Sergey Petrunya	a0de3e0485	MDEV-4556 Server crashes in SEL_ARG::rb_insert with index_merge+index_merge_sort_union, FORCE INDEX - merge_same_index_scans() may put the same SEL_ARG tree in multiple result plans. make it call incr_refs() on the SEL_ARG trees that it does key_or() on, because key_or(sel_arg_tree_1, sel_arg_tree_2) call may invalidate SEL_ARG trees pointed by sel_arg_tree_1 and sel_arg_tree_2.	13 years ago

Sergei Golubchik	78cc6db44a	MDEV-4667 DATE('string') incompability between mysql and mariadb Cleanup: remove TIME_FUZZY_DATE.
