unknown	764eeeee74	Fix for LP BUG#910123 MariaDB 5.3.3 causes 1093 error on Drupal Problem was that now we can merge derived table (subquery in the FROM clause). Fix: in case of detected conflict and presence of derived table "over" the table which cased the conflict - try materialization strategy.	14 years ago

Sergey Petrunya	c9355dc279	BUG#928048: Query containing IN subquery with OR in the where clause returns a wrong result - Make equality propagation work correctly when done inside the OR branches	14 years ago
Igor Babaev	c8bbe06ac7	Fixed LP bug #925985 . If the flag 'optimize_join_buffer_size' is set to 'off' and the value of the system variable 'join_buffer_size' is greater than the value of the system variable 'join_buffer_space_limit' than no join cache can be employed to join tables of the executed query. A bug in the function JOIN_CACHE::alloc_buffer allowed to use join buffer even in this case while another bug in the function revise_cache_usage could cause a crash of the server in this case if the chosen execution plan for the query contained outer join or semi-join operation.	14 years ago
unknown	27dfa45e70	When we fail during slave thread initialisation, keep mi->run_lock locked until we have finished clean up. Previously, the code released the lock without marking that the thread was running. This allowed a new slave thread to start while the old one was still in the middle of cleaning up, causing assertions and probably general mayhem.	14 years ago

Vladislav Vaintroub	e2cb03c980	Fix for MDEV-140, LPBug#930145 - broken SSL connectivity for some connectors	14 years ago
Vladislav Vaintroub	b3e15f8389	A recent change in the server protocol code broke SSL connection for some client libraries. Protocol documentation (http://forge.mysql.com/wiki/MySQL_Internals_ClientServer_Protocol) says that initial packet sent by client if client wants SSL, consists of client capability flags only (4 bytes or 2 bytes edependent on protocol versionl). Some clients happen to send more in the initial SSL packet (C client, Python connector), while others (Java, .NET) follow the docs and send only client capability flags. A change that broke Java client was a newly introduced check that frst client packet has 32 or more bytes. This is generally wrong, if client capability flags contains CLIENT_SSL. Also, fixed the code such that read max client packet size and charset in the first packet prior to SSL handshake. With SSL, clients do not have to send this info, they can only send client flags. This is now fixed such that max packet size and charset are not read prior to SSL handshake, in case of SSL they are read from the "complete" client authentication packet after SSL initialization.	14 years ago

unknown	3d61c1399d	lp:910817: Race condition in kill_threads_for_user() The code was accessing a pointer in a mem_root that might be freed by another concurrent thread. Fix by moving the access to be done while the LOCK_thd_data is held, preventing the memory from being freed too early.	14 years ago

unknown	52d4103ccc	Fixed DELETE issues of view over view over table.	14 years ago
Igor Babaev	046988661d	Back-ported the fix for bug #12831587 from mysql-5.6 code line. The comment for the fix commit says: Due to the changes required by ICP we first copy a row from the InnoDB format to the MySQL row buffer and then copy it to the pre-fetch queue. This was done for the non-ICP code path too. This change removes the double copy for the latter.	14 years ago
unknown	b9616d815d	Added 5.2 test result delimiter	14 years ago
unknown	d6e1377ac2	Fix check of view updatability in case of underlying view changes its updatability. For single table update/insert added deep check of single tables (single_table_updatable()). For multi-table view insert added additional check of target table (check_view_single_update). Multi-update was correct. Test suite for all cases added.	14 years ago
Igor Babaev	94c316069e	Applied the patch from mysql-5.6 code line that fixed a significant performance drop for high concurrency bechmarks (bug #11765850 - 58854). Here's the comment of the patch commit: The bug is that the InnoDB pre-fetch cache was not being used in row_search_for_mysql(). Secondly the changeset that planted the bug also introduced some inefficient code. It would read an extra row, convert it to MySQL row format (for ICP==off), copy the row to the pre-fetch cache row buffer, then check for cache overflow and dequeue the row that was pushed if there was a possibility of a cache overflow.	14 years ago

Sergey Petrunya	12bd3dfe29	BUG#923246: Loosescan reports different result than other semijoin methods - If LooseScan is used with quick select, require that quick select produces data in key order (this disables use of MRR, which can return data in arbitrary order).	14 years ago

Igor Babaev	5ca1dd8f0b	Fixed LP bug #922971 . Applied the fix for bug #12546542 from the mysql-5.6 code line: JOIN_CACHE::join_records forgot to reset JOIN_TAB::first_unmatched in some cases.	14 years ago

Igor Babaev	4e2b6d45e0	Back-ported test cases for bug #59919 of mysql-5.6 code line. The bug could not be reproduced in the latest release of mariadb-5.3 as it was was fixed by Sergey Petrunia when working on the problems concerning outer joins within in subqueries converted to semi-joins.	14 years ago

Sergey Petrunya	53fde5bb6f	BUG#922254: Assertion `0' failed at item_cmpfunc.cc:5899: Item* Item_equal::get_first(JOIN_TAB, Item) Fixed Item* Item_equal::get_first(JOIN_TAB context, Item field_item) to work correctly in the case where: - context!= NO_PARTICULAR_TAB, it points to a table within SJ-Materialization nest - field_item points to an item_equal that has a constant Item_field but does not have any fields from tables that are within semi-join nests.	14 years ago
Sergey Petrunya	8a8e5a50c9	Fix compile failure when built without query cache: define QUERY_CACHE_DB_LENGTH_SIZE 0, just like it is done with QUERY_CACHE_FLAGS_SIZE.	14 years ago
Sergey Petrunya	a0c1ada91c	Sort counters by name (will this make them show in the same order on all platforms?)	14 years ago
Sergey Petrunya	424f56b3ba	BUG#920713: Wrong result (missing rows) with firstmatch+BNL, IN subquery, ... - Disable use of join cache when we're using FirstMatch strategy, and the join order is such that subquery's inner tables are interleaved with outer. Join buffering code is incapable of handling such join orders. - The testcase requires use of @@debug_optimizer_prefer_join_prefix to hit the bug, but I'm pushing it anyway (including the mention of the variable in .test file), so that it can be found and enabled when/if we get something comparable in the main tree.	14 years ago
Sergey Petrunya	364c07934c	Merge	14 years ago
Sergey Petrunya	73cc529b51	BUG#920255: Wrong result (extra rows) with loosescan and IN subquery The problem was that LooseScan execution code assumed that tab->key holds the index used for looseScan. This is only true when range or full index scan are used. In case of ref access, the index is in tab->ref.key (and tab->index==0 which explains how LooseScan passed tests with ref access: they used one index) Fixed by setting/using loosescan_key, which always the correct index#.	14 years ago
