From 42d1e3c4574c375e6f10fb1b1c5c0122689cd25e Mon Sep 17 00:00:00 2001 From: "evgen@moonbone.local" <> Date: Sun, 8 Jul 2007 18:13:04 +0400 Subject: [PATCH 01/17] Bug#29310: An InnoDB table was updated when the data wasn't actually changed. When a table is being updated it has two set of fields - fields required for checks of conditions and fields to be updated. A storage engine is allowed not to retrieve columns marked for update. Due to this fact records can't be compared to see whether the data has been changed or not. This makes the server always update records independently of data change. Now when an auto-updatable timestamp field is present and server sees that a table handle isn't going to retrieve write-only fields then all of such fields are marked as to be read to force the handler to retrieve them. --- mysql-test/include/mix1.inc | 24 ++++++++++++++++++++++++ mysql-test/r/innodb_mysql.result | 28 ++++++++++++++++++++++++++++ sql/sql_insert.cc | 3 ++- sql/sql_update.cc | 11 +++++++++++ 4 files changed, 65 insertions(+), 1 deletion(-) diff --git a/mysql-test/include/mix1.inc b/mysql-test/include/mix1.inc index d8034e19898..03df7c33a00 100644 --- a/mysql-test/include/mix1.inc +++ b/mysql-test/include/mix1.inc @@ -948,5 +948,29 @@ unlock tables; select * from t1; drop tables t1; +# +# Bug#29310: An InnoDB table was updated when the data wasn't actually changed. +# +create table t1(f1 varchar(5) unique, f2 timestamp NOT NULL DEFAULT + CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP); +insert into t1(f1) values(1); +--replace_column 1 # +select @a:=f2 from t1; +--sleep 5 +update t1 set f1=1; +--replace_column 1 # +select @b:=f2 from t1; +select if(@a=@b,"ok","wrong"); +--sleep 5 +insert into t1(f1) values (1) on duplicate key update f1="1"; +--replace_column 1 # +select @b:=f2 from t1; +select if(@a=@b,"ok","wrong"); +--sleep 5 +insert into t1(f1) select f1 from t1 on duplicate key update f1="1"; +--replace_column 1 # +select @b:=f2 from t1; +select if(@a=@b,"ok","wrong"); +drop table t1; --echo End of 5.1 tests diff --git a/mysql-test/r/innodb_mysql.result b/mysql-test/r/innodb_mysql.result index db912c650c3..93b78143de7 100644 --- a/mysql-test/r/innodb_mysql.result +++ b/mysql-test/r/innodb_mysql.result @@ -951,4 +951,32 @@ NULL 1 Two drop tables t1; +create table t1(f1 varchar(5) unique, f2 timestamp NOT NULL DEFAULT +CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP); +insert into t1(f1) values(1); +select @a:=f2 from t1; +@a:=f2 +# +update t1 set f1=1; +select @b:=f2 from t1; +@b:=f2 +# +select if(@a=@b,"ok","wrong"); +if(@a=@b,"ok","wrong") +ok +insert into t1(f1) values (1) on duplicate key update f1="1"; +select @b:=f2 from t1; +@b:=f2 +# +select if(@a=@b,"ok","wrong"); +if(@a=@b,"ok","wrong") +ok +insert into t1(f1) select f1 from t1 on duplicate key update f1="1"; +select @b:=f2 from t1; +@b:=f2 +# +select if(@a=@b,"ok","wrong"); +if(@a=@b,"ok","wrong") +ok +drop table t1; End of 5.1 tests diff --git a/sql/sql_insert.cc b/sql/sql_insert.cc index eeac5e7c4fe..7717d2c92c1 100644 --- a/sql/sql_insert.cc +++ b/sql/sql_insert.cc @@ -1419,7 +1419,8 @@ int write_record(THD *thd, TABLE *table,COPY_INFO *info) goto before_trg_err; table->file->restore_auto_increment(prev_insert_id); - if ((table->file->ha_table_flags() & HA_PARTIAL_COLUMN_READ) || + if ((table->file->ha_table_flags() & HA_PARTIAL_COLUMN_READ && + !bitmap_is_subset(table->write_set, table->read_set)) || compare_record(table)) { if ((error=table->file->ha_update_row(table->record[1], diff --git a/sql/sql_update.cc b/sql/sql_update.cc index ef1f46bfdd2..6927835762b 100644 --- a/sql/sql_update.cc +++ b/sql/sql_update.cc @@ -231,6 +231,17 @@ int mysql_update(THD *thd, if (cond_value == Item::COND_FALSE) limit= 0; // Impossible WHERE } + + /* + If a timestamp field settable on UPDATE is present then to avoid wrong + update force the table handler to retrieve write-only fields to be able + to compare records and detect data change. + */ + if (table->file->ha_table_flags() & HA_PARTIAL_COLUMN_READ && + table->timestamp_field && + (table->timestamp_field_type == TIMESTAMP_AUTO_SET_ON_UPDATE || + table->timestamp_field_type == TIMESTAMP_AUTO_SET_ON_BOTH)) + bitmap_union(table->read_set, table->write_set); // Don't count on usage of 'only index' when calculating which key to use table->covering_keys.clear_all(); From ff3fd46c329e3e37a4e4d342fd7a429c7f8a173c Mon Sep 17 00:00:00 2001 From: "evgen@moonbone.local" <> Date: Mon, 9 Jul 2007 01:23:33 +0400 Subject: [PATCH 02/17] Bug#29461: Sort order of the collation wasn't used when comparing characters with the space character. When the my_strnncollsp_simple function compares two strings and one is a prefix of another then this function compares characters in the rest of longer key with the space character to find whether the longer key is greater or less. But the sort order of the collation isn't used in this comparison. This may lead to a wrong comparison result, wrongly created index or wrong order of the result set of a query with the ORDER BY clause. Now the my_strnncollsp_simple function uses collation sort order to compare the characters in the rest of longer key with the space character. --- mysql-test/r/ctype_collate.result | 8 ++++++++ mysql-test/t/ctype_collate.test | 11 +++++++++++ strings/ctype-simple.c | 2 +- 3 files changed, 20 insertions(+), 1 deletion(-) diff --git a/mysql-test/r/ctype_collate.result b/mysql-test/r/ctype_collate.result index 52ee76d1948..5c9bb93103e 100644 --- a/mysql-test/r/ctype_collate.result +++ b/mysql-test/r/ctype_collate.result @@ -603,3 +603,11 @@ check table t1 extended; Table Op Msg_type Msg_text test.t1 check status OK drop table t1; +create table t1 (a varchar(2) character set latin7 collate latin7_general_ci,key(a)); +insert into t1 set a=0x4c20; +insert into t1 set a=0x6c; +insert into t1 set a=0x4c98; +check table t1 extended; +Table Op Msg_type Msg_text +test.t1 check status OK +drop table t1; diff --git a/mysql-test/t/ctype_collate.test b/mysql-test/t/ctype_collate.test index 4bbae42559a..cfef8dfe81a 100644 --- a/mysql-test/t/ctype_collate.test +++ b/mysql-test/t/ctype_collate.test @@ -218,3 +218,14 @@ insert into t1 set f1=0x3F3F1E563F; insert into t1 set f1=0x3F3F; check table t1 extended; drop table t1; + +# +# Bug#29461: Sort order of the collation wasn't used when comparing characters +# with the space character. +# +create table t1 (a varchar(2) character set latin7 collate latin7_general_ci,key(a)); +insert into t1 set a=0x4c20; +insert into t1 set a=0x6c; +insert into t1 set a=0x4c98; +check table t1 extended; +drop table t1; diff --git a/strings/ctype-simple.c b/strings/ctype-simple.c index fca5607e152..8b1b0d6790d 100644 --- a/strings/ctype-simple.c +++ b/strings/ctype-simple.c @@ -179,7 +179,7 @@ int my_strnncollsp_simple(CHARSET_INFO * cs, const uchar *a, uint a_length, } for (end= a + a_length-length; a < end ; a++) { - if (*a != ' ') + if (map[*a] != ' ') return (map[*a] < ' ') ? -swap : swap; } } From 3e9679e1fa36a1d788da106cd2629a0e87f1a630 Mon Sep 17 00:00:00 2001 From: "gkodinov/kgeorge@magare.gmz" <> Date: Mon, 9 Jul 2007 17:41:24 +0300 Subject: [PATCH 03/17] Bug #29070: Error in spatial index 1.
