This is a 10.2+ part of a jira task The two bugs regarding virtual column marking have been fixed: 1. UPDATE of a partitioned table, where the optimizer has chosen a secondary index to make a filesort; 2. INSERT into a table with a nonblob field generated from a blob, with binlog enabled and binlog_row_image=noblob. 3. DELETE from a view on a table with virtual column. Generally the assertion happens from update_virtual_fields() call These bugs are root-caused by missing field marking for dependant fields of a virtual column. Therefore a fix is: mark all the fields involved in the vcol expression by calling field->register_field_in_read_map() instead just setting a single bit. 3 was reproducible only on 10.4+, however the problem might has just been invisible in the earlier versions. The fix is applicable to 10.2-10.3 as well.
