There are still some bugs in the code. btr_store_big_rec_extern_fields(): Remove assertion on dict_table_is_zip() to ease testing. btr_free_externally_stored_field(): Test page_zip instead of dict_table_is_zip(). page_zip_write_rec(): Add parameter "create". Try to handle externally stored columns. rec_offs_any_extern(): Correct the function comment. Add rec_offs_n_extern() and page_zip_get_n_prev_extern(). page_zip_dir_decode(): Replace assertion with if (...) return(FALSE). page_zip_decompress(): Do not clear page_zip->n_blobs after counting the BLOBs. page_zip_write_blob_ptr(): Use page_zip_get_n_prev_extern(). Correct an off-by-one error in memcpy().

btr_cur_pessimistic_update(): Remove extraneous page_zip_write_rec() call. btr_cur_set_ownership_of_extern_field(): Simplify the logic. row_upd_rec_in_place(): Make use of parameter "index" in debug assertions. page_zip_write_rec(): Remove TODO comment about redo log record. The write will already be covered by higher-level log entries.

of clustered indexes. Previously, parts of the code assumed that these columns would exist on all leaf pages. Simplify the update-in-place of these columns. Add inline function dict_index_is_clust() to replace all tests index->type & DICT_CLUSTERED. Remove the redo log entry types MLOG_ZIP_WRITE_TRX_ID and MLOG_ZIP_WRITE_ROLL_PTR, because the modifications to these columns are covered by logical logging. Fuse page_zip_write_trx_id() and page_zip_write_roll_ptr() into page_zip_write_trx_id_and_roll_ptr(). page_zip_dir_add_slot(), page_zip_available(): Add flag "is_clustered", so that no space will be reserved for TRX_ID and ROLL_PTR on leaf pages of secondary indexes. page_zip_apply_log(): Flag an error when val==0 is encoded with two bytes. page_zip_write_rec(): Add debug assertions that there is enough space available for the entry before copying the data bytes of the record.

row_upd_rec_in_place(), page_zip_write_rec(): Add parameter "index". page_dir_set_n_heap(): Add a debug assertion that on compressed pages, n_heap will always be incremented by one. Improve code formatting. page_zip_dir_add_slot(): New function, called from page_cur_insert_rec_low() after page_mem_alloc_heap(). rec_set_n_owned_new(): Do not call page_zip_rec_set_owned() on the supremum record. rec_offs_make_valid(): Add debug assertions. page_zip_dir_user_size(): Correct an off-by-one error in the debug assertion. page_zip_apply_log(): Add parameter trx_id_col. Skip trx_id and roll_ptr. page_zip_decompress(): Simplify the handling of "storage" in the loop that copies the uncompressed fields. page_zip_write_rec(): Store trx_id and roll_ptr separately. page_zip_write_trx_id(), page_zip_write_roll_ptr(): Fix off-by-one errors. page_cur_insert_rec_low(): Call page_zip_dir_add_slot() after page_mem_alloc_heap(). Remove some redundant assertions. Pass page_zip to page_dir_split_slot().

BLOB pointers, trx_id, and roll_ptr. btr_empty(), btr_create(), page_create(): Add parameter "index", as some index information will be encoded on the compressed page. Define REC_NODE_PTR_SIZE as 4. Allow btr_page_reorganize() and btr_page_reorganize_low() to fail. Define the error code DB_ZIP_OVERFLOW. Make row_ins_index_entry_low() static. page0zip: Encode the index, log reorganized records, and store uncompressed fields separately from the compressed data stream.
