During a table-rebuilding online ALTER TABLE, if dict_index_t::remove_instant() was invoked on the source table (because it became empty), we would inadvertently change the way how log records are written and parsed. We must keep the online_log format unchanged throughout the whole table-rebuilding operation. dict_col_t::def_t: Name the type of dict_col_t::def_val. rec_get_n_add_field_len(), rec_set_n_add_field(): Define globally, because these will be needed in row_log_table_low(). rec_init_offsets_temp(), rec_init_offsets_comp_ordinary(): Add the parameter def_val for explicitly passing the default values of the instantly added columns of the source table, so that dict_index_t::instant_field_value() will not be called during row_log_table_apply(). This allows us to consistently parse the online_log records, even if the source table was converted to the canonical non-instant format during the rebuild operation. row_log_t::non_core_fields[]: The default values of the instantly added columns on the source table; copied during ha_innobase::prepare_inplace_alter_table() while the table is exclusively locked. row_log_t::instant_field_value(): Accessor to non_core_fields[], analogous to dict_index_t::instant_field_value(). row_log_table_low(): Add fake_extra_size bytes to the record header if the source table was converted to the canonical format during the operation. row_log_allocate(): Initialize row_log_t::non_core_fields. |
