From f0d1ac25c349f09f2512d75f4e12f39d3a7729c3 Mon Sep 17 00:00:00 2001 From: unknown <holyfoot/hf@mysql.com/hfmain.(none)> Date: Thu, 23 Aug 2007 23:34:48 +0500 Subject: [PATCH] Bug #28430 Failure in replication of innodb partitioned tables on row/mixed format. In the ha_partition::position() we didn't calculate the number of the partition of the record. We used m_last_part value instead, relying on that it is set in other place like previous call of a method like ::write_row(). In replication we don't call any of these befor position(). Delete_rows_log_event::do_exec_row calls find_and_fetch_row. In case of InnoDB-based PARTITION table, we have HA_PRIMARY_KEY_REQUIRED_FOR_POSITION enabled, so use position() / rnd_pos() calls to fetch the record. Fixed by adding partition_id calculation to the ha_partition::position() sql/ha_partition.h: Bug #28430 Failure in replication of innodb partitioned tables on row/mixed format. column_bitmaps_signal interface added sql/ha_partition.cc: Bug #28430 Failure in replication of innodb partitioned tables on row/mixed format. Calculate the number of the partition in ha_partition::position(). ha_partition::column_bitmaps_signal() implemented mysql-test/r/partition_pruning.result: Bug #28430 Failure in replication of innodb partitioned tables on row/mixed format. test result fixed --- mysql-test/r/partition_pruning.result | 4 ++-- sql/ha_partition.cc | 14 +++++++++++++- sql/ha_partition.h | 1 + 3 files changed, 16 insertions(+), 3 deletions(-) diff --git a/mysql-test/r/partition_pruning.result b/mysql-test/r/partition_pruning.result index 9595676016c..776e6f3a15a 100644 --- a/mysql-test/r/partition_pruning.result +++ b/mysql-test/r/partition_pruning.result @@ -631,7 +631,7 @@ flush status; delete from t2 where b > 5; show status like 'Handler_read_rnd_next'; Variable_name Value -Handler_read_rnd_next 1215 +Handler_read_rnd_next 1115 show status like 'Handler_read_key'; Variable_name Value Handler_read_key 0 @@ -645,7 +645,7 @@ flush status; delete from t2 where b < 5 or b > 3; show status like 'Handler_read_rnd_next'; Variable_name Value -Handler_read_rnd_next 1215 +Handler_read_rnd_next 1115 show status like 'Handler_read_key'; Variable_name Value Handler_read_key 0 diff --git a/sql/ha_partition.cc b/sql/ha_partition.cc index 2c28d5087d4..91eaf66e4e3 100644 --- a/sql/ha_partition.cc +++ b/sql/ha_partition.cc @@ -3235,9 +3235,14 @@ end_dont_reset_start_part: void ha_partition::position(const uchar *record) { - handler *file= m_file[m_last_part]; + handler *file; DBUG_ENTER("ha_partition::position"); + if (unlikely(get_part_for_delete(record, m_rec0, m_part_info, &m_last_part))) + m_last_part= 0; + + file= m_file[m_last_part]; + file->position(record); int2store(ref, m_last_part); memcpy((ref + PARTITION_BYTES_IN_POS), file->ref, @@ -5587,6 +5592,13 @@ int ha_partition::indexes_are_disabled(void) } +void ha_partition::column_bitmaps_signal() +{ + handler::column_bitmaps_signal(); + bitmap_union(table->read_set, &m_part_info->full_part_field_set); +} + + /**************************************************************************** MODULE Partition Share ****************************************************************************/ diff --git a/sql/ha_partition.h b/sql/ha_partition.h index 895f001fa6a..c3145b7c14c 100644 --- a/sql/ha_partition.h +++ b/sql/ha_partition.h @@ -449,6 +449,7 @@ private: int handle_ordered_next(uchar * buf, bool next_same); int handle_ordered_prev(uchar * buf); void return_top_record(uchar * buf); + void column_bitmaps_signal(); public: /* -------------------------------------------------------------------------
