btr_page_create(): Remove parameters "prev" and "next". The pointers to adjacent B-tree pages will be set in the caller before any user records are inserted. Remove the redo log entry type MLOG_ZIP_ROOT_RAISE, since btr_root_raise_and_insert() will not defer modifications to the compressed page. btr_attach_half_pages(): Add parameter new_page_zip.

MLOG_ZIP_COMPRESS and MLOG_ZIP_DECOMPRESS with higher-level entry types. Implement the logging and crash recovery of MLOG_ZIP_PAGE_CREATE. page_create_zip(): New function for creating a compressed B-tree page. page_parse_create_zip(): New function for applying a MLOG_ZIP_PAGE_CREATE redo log record. btr_page_create(): Remove the prototype. Add parameters page_zip, level, prev, and next. btr0btr.c: Eliminate page_zip_compress() calls where possible. page_zip_alloc(), page_zip_compress(), page_zip_decompress(), page_zip_clear_rec(): Remove parameter mtr. recv_parse_or_apply_log_rec_body(): Handle MLOG_ZIP_PAGE_CREATE. Add TODO comments for the other added redo log entry types.

page_zip_parse_write_blob_ptr(): New function for applying the redo log record MLOG_ZIP_WRITE_BLOB_PTR. page_zip_write_blob_ptr(): Write the necessary information to the redo log. page0zip.c: Tighten the assertions to ensure that blob_ptr < page_zip->n_blobs. page_zip_write_node_ptr(): Use memcpy() instead of mach_write_to_4().

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.

btr_create(): page_zip_compress() returns FALSE on failure. page_zip_write_header(): Write to page_zip->data[] instead of page_zip[]. buf_flush_init_for_writing(): Add parameter page_zip and set the fields also in the header of the compressed page. btr_cur_search_to_nth_level(): Add ut_ad() on page_zip_validate().

compressed pages. btr_root_raise_and_insert(): Distinguish root_page_zip and new_page_zip. btr_cur_set_ownership_of_extern_field(): Do not log the write on the uncompressed page if it will be logged for page_zip. lock_rec_insert_check_and_lock(), lock_sec_rec_modify_check_and_lock(): Update the max_trx_id field also on the compressed page. mlog_write_ulint(): Add UNIV_UNLIKELY hints. Remove trailing white space. mlog_log_string(): Remove trailing white space. rec_set_field_extern_bits(): Remove parameter mtr, as the write will either occur in the heap, or it will be logged at a higher level. recv_parse_or_apply_log_rec_body(), page_zip_write_header(): Add log record type MLOG_ZIP_WRITE_HEADER. page_header_set_field(): Pass mtr=NULL to page_zip_write_header(). page_header_reset_last_insert(): Pass mtr to page_zip_write_header(). btr_page_set_index_id(), btr_page_set_level(), btr_page_set_next(), btr_page_set_prev(): Pass mtr to page_zip_write_header(). row_upd_rec_sys_fields(): Pass mtr=NULL to page_zip_write_trx_id() and page_zip_write_roll_ptr(), since the write will be logged at a higher level. page_zip_write_header(): Add parameter mtr. page_zip_write_header_log(): New function. Remove rec_set_nth_field_extern_bit(). Make rec_set_nth_field_extern_bit_old() static. Rename rec_set_nth_field_extern_bit_new() to rec_set_field_extern_bits_new() and make it static. row_ins_index_entry_low(): Remove bogus TODO comment.

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.
