MDEV-11636 Extra persistent columns on slave always gets NULL in RBR
The patch looks ok now.
Problem:- In replication if slave has extra persistent column then these column are not computed while applying write-set from master.
Solution:- While applying write-set from server, we will generate values for extra persistent columns.
"write-set" is a Galera term. In replication, they are refered to as binlog events, or row events in the specific case of row-based replication events.

You do not need to sync_slave_with_master for SELECT.

You moved this from write_row() to unpack_row(), so I assume this was to fix the similar bug for updates? - Kristian.
