If UNIV_DEBUG or UNIV_BLOB_LIGHT_DEBUG is enabled, add !rec_offs_any_null_extern() assertions, ensuring that records do not contain null pointers to externally stored columns in inappropriate places. btr_cur_optimistic_update(): Assert !rec_offs_any_null_extern(). Incomplete records must never be updated or deleted. This assertion will cover also the pessimistic route. row_build(): Assert !rec_offs_any_null_extern(). Search tuples must never be built from incomplete index entries. row_rec_to_index_entry(): Assert !rec_offs_any_null_extern() unless ROW_COPY_DATA is requested. ROW_COPY_DATA is used for multi-versioning, and therefore it might be valid to copy the most recent (uncommitted) version while it contains a null pointer to off-page columns. row_vers_build_for_consistent_read(), row_vers_build_for_semi_consistent_read(): Assert !rec_offs_any_null_extern() on all versions except the most recent one. trx_undo_prev_version_build(): Assert !rec_offs_any_null_extern() on the previous version. rb:682 approved by Sunny Bains |
