When importing a tablespace, we must initialize dummy DEFAULT NULL values for any instantly added columns in order to avoid a debug assertion failure when PageConverter::update_records() invokes rec_get_offsets(). Finally, when the operation completes, we must evict and reload the table definition, so that the correct default values for instantly added columns will be loaded. ha_innobase::discard_or_import_tablespace(): On successful IMPORT TABLESPACE, evict and reload the table definition, so that btr_cur_instant_init() will load the correct metadata. PageConverter::update_index_page(): Fill in dummy DEFAULT NULL values for instantly added columns. These will be replaced upon the completion of the operation by evicting and reloading the metadata. row_discard_tablespace(): Invoke dict_table_t::remove_instant(). After DISCARD TABLESPACE, the table is no longer in "instant ALTER" format, because there is no data file attached. |
