revision-id: eb010f9199320e8eb6908782b8c2eca62042cdd9 (mariadb-10.4.11-38-geb010f9) parent(s): 7ea413ac2d80c7f03d1dbad90ac30ecddd8b2835 author: Igor Babaev committer: Igor Babaev timestamp: 2020-02-18 22:49:42 -0800 message: MDEV-21610 Different query results from 10.4.11 to 10.4.12 This patch fixes the following defects/bugs. 1. If BKA[H] algorithm was used to join a table for which the optimizer had decided to employ a rowid filter the filter actually was not built. 2. The patch for the bug MDEV-21356 that added the code canceling pushing rowid filter into an engine for the table joined with employment of BKA[H] and MRR was not quite correct for Innodb engine because this cancellation was done after InnoDB code had already bound the the pushed filter to internal InnoDB structures. --- mysql-test/main/rowid_filter_innodb.result | 333 +++++++++++++++++++++++++++++ mysql-test/main/rowid_filter_innodb.test | 153 +++++++++++++ sql/multi_range_read.cc | 41 ++-- sql/multi_range_read.h | 5 +- sql/opt_range.cc | 3 +- sql/sql_join_cache.cc | 2 + 6 files changed, 516 insertions(+), 21 deletions(-) diff --git a/mysql-test/main/rowid_filter_innodb.result b/mysql-test/main/rowid_filter_innodb.result index c59b95b..9423fb1 100644 --- a/mysql-test/main/rowid_filter_innodb.result +++ b/mysql-test/main/rowid_filter_innodb.result @@ -2522,3 +2522,336 @@ id select_type table type possible_keys key key_len ref rows r_rows filtered r_f 1 SIMPLE t1 index a,b PRIMARY 4 NULL 3008 3008.00 1.36 0.00 Using where DROP TABLE t1;
