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
Igor Babaev	008371b627	Backported from maria-5.5 the fix in the patch for mdev-4418 that had been discovered when merging the patch from 5.3 into 5.5.	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	752d5d022d	Merge	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	7ba78277b4	Merge 5.1->5.2	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

Vladislav Vaintroub	6bef652d91	MDEV-4409 - Fix deadlock in MySQL key cache code, that can happen if there is a key cache resize running in parallel with an update. If there is a key cache resize,a thread writing to key cache, will pause waiting until resize finishes. However this thread is won't be woken, because resize does not signaling waiters anymore. This is a regression introduced in WL#86(segmented MyISAM key cache) The fix is to unconditionally release threads waiting on resize_queue when resize finishes, as in pre-WL#86 code.	13 years ago

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

Sergey Petrunya	445fc7ba5d	MDEV-4482: main.windows test fails in buildbot with result mismatch - Rollback an earlier patch (was pushed into 5.3 instead of 5.5)	13 years ago
Igor Babaev	920c479c6e	Fixed bug mdev-4336. When iterating over a list of conditions using List_iterator the function remove_eq_conds should skip all predicates that replace a condition from the list. Otherwise it can come to an infinite recursion.	13 years ago
Igor Babaev	b249680fd1	Made consistent handling of the predicates of the form <non-nullable datatime field> IS NULL in outer joins with that in inner joins. Previously such condition was transformed into the condition <non-nullable datatime field> = 0 unless the field belonged to an inner table of an outer join. In this case the predicate was interpreted as for any other field. Now if the field in the predicate <non-nullable datatime field> IS NULL belongs to an inner table of an outer join the predicate is transformed into the disjunction <non-nullable datatime field> = 0 OR <non-nullable datatime field> IS NULL. This is fully compatible with the semantics of such predicates in 5.5.	13 years ago
Igor Babaev	86f43c3077	Fixed bug mdev-4274. This bug was the result of incompleteness of the patch for bug mdev-4177. When an OR condition is simplified to a single conjunct it is merged into the embedding AND condition. Multiple equalities are also merged, and any field item involved in those equality should acquire a pointer to a the multiple equality formed by this merge.	13 years ago
