Part #2: - row_search_mvcc() should return DB_INTERRUPTED when it got - Move the sync point from innodb internals to handler_rowid_filter_check() where other storage engines can use it too - Add a similar syncpoint for the ICP check. - Add a bigger test and test coverage for Rowid Filter with MyISAM - Add test coverage for killed-during-ICP-check scenario
