An earlier patch for MDEV-13577 fixed the most common instances of this, but missed one case for tables without primary key when the scan reaches the end of the table. This patch adds similar code to handle this case, converting the error to HA_ERR_RECORD_CHANGED when doing optimistic parallel apply. Signed-off-by: Kristian Nielsen <knielsen@knielsen-hq.org>
