Aleksey Midenkov	160d97a4aa	MDEV-18734 ASAN heap-use-after-free upon sorting by blob column from partitioned table ... ha_partition stores records in array of m_ordered_rec_buffer and uses it for prio queue in ordered index scan. When the records are restored from the array the blob buffers may be already freed or rewritten. The solution is to take temporary ownership of cached blob buffers via String::swap(). When the record is restored from m_ordered_rec_buffer the ownership is returned to table fields. Cleanups: init_record_priority_queue(): removed needless !m_ordered_rec_buffer check as there is same assertion few lines before. dbug_print_row() for arbitrary row pointer	2021-08-05 23:48:02 +03:00
Sergei Golubchik	88a0bb83df	MDEV-15626 Assertion on update virtual column in partitioned table ... table.cc: virtual columns must be computed for INSERT, if they're part of the partitioning expression. this change broke gcol.gcol_partition_innodb. fix CHECK TABLE for partitioned tables and vcols. sql_partition.cc: mark prerequisite base columns in full_part_field_set ha_partition.cc initialize vcol_set accordingly	2018-05-10 12:48:23 +02:00
