Marko Mäkelä 63478e72de MDEV-21098: Assertion failure in rec_get_offsets_func() ... The function rec_get_offsets_func() used to hit ut_error due to an invalid rec_get_status() value of a ROW_FORMAT!=REDUNDANT record. This fix is twofold: We will not only avoid a crash on corruption in this case, but we will also make more effort to validate each record every time we are iterating over index page records. rec_get_offsets_func(): Do not crash on a corrupted record. page_rec_get_nth(): Return nullptr on error. page_dir_slot_get_rec_validate(): Like page_dir_slot_get_rec(), but validate the pointer and return nullptr on error. page_cur_search_with_match(), page_cur_search_with_match_bytes(), page_dir_split_slot(), page_cur_move_to_next(): Indicate failure in a return value. page_cur_search(): Replaced with page_cur_search_with_match(). rec_get_next_ptr_const(), rec_get_next_ptr(): Replaced with page_rec_get_next_low(). TODO: rtr_page_split_initialize_nodes(), rtr_update_mbr_field(), and possibly other SPATIAL INDEX functions fail to properly handle errors.
