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.	Igor Babaev		12 years ago
3406	Applied the patch from mysql-5.6 code line that fixed 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.

3404	fix for LP BUG#921878. fix for LP BUG#921878. Problem was in try to check/use Item_direct_ref of derived view when we have to use real Item_field under it.	sanja at montyprogra...		12 years ago

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).

3397	Fix compile failure when built without query cache: define 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.	Sergey Petrunya		12 years ago

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.	Sergey Petrunya		12 years ago
