and to the file space header (FSP_PAGE_ZIP_SIZE, renamed from
FSP_LOWEST_NO_WRITE).
fil_space_struct: Add zip_size.
dict_table_struct: Embed zip_size in flags.
dict_table_zip_size(): Infer zip_size from table->flags.
dict_sys_tables_get_zip_size(): Read zip_size from SYS_TABLES.TYPE.
fil_space_get_zip_size(): Read zip_size from the file space header.
Add the redo log entry type MLOG_ZIP_FILE_CREATE.
dict_mem_table_create(): Account for DICT_TF_COMPRESSED in a debug assertion.
btr_store_big_rec_extern_fields(), btr_free_externally_stored_field(),
btr_copy_externally_stored_field(): Implement the disk format for
compressed BLOB pages.
btr_copy_externally_stored_field(): Improve error reporting and handling
when decompressing BLOB pages.
buf_flush_init_for_writing(), buf_page_is_corrupted(), buf_page_print():
Account for compressed BLOB pages (FIL_PAGE_TYPE_ZBLOB).
buf_calc_zblob_page_checksum(): New function.
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.
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.
that will require complete index information.
dict_create_index_step(): invoke dict_index_add_to_cache() before btr_create()
dict_index_remove_from_cache(): make public
dict_index_get_if_in_cache_low(): new function, for holding dict_sys->mutex
buf_flush_init_for_writing(): remove the temporary hook to page_zip_compress()
page_create(): add temporary hook to page_zip_compress()
