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()
page_zip_dir_decode(): Correct the handling of the free list.
page_zip_set_extra_bytes(): Remove off-by-one error in the first loop.
page_zip_apply_log(): Replace parameter end with size, and let end=data+size.
page_zip_decompress(): Properly handle pages where the first user record has
more than REC_N_NEW_EXTRA_BYTES extra bytes.
page_delete_rec_list_end(): Remove page_zip_temp. This operation will be
done completely in-place on page_zip. If page_zip is specified, clear the
data bytes and the info and status bits of deleted records and clear the
removed directory slots.
page_dir_delete_slot(): Clear the last directory slot, which will be removed.
page_set_max_trx_id(), page_update_max_trx_id(): Add parameter page_zip.
Check that page_zip_decompress() is never called after modifying the
header or trailer of the compressed page, i.e., that page_zip_decompress()
will restore the uncompressed page as it was before the failed operation.
page_header_reset_last_insert(): Add page_zip parameter.
rec_get_next_ptr(): Return a pointer to the same page, or NULL.
page_dir_delete_slot(): Fix off-by-one errors.
Add page_zip parameter to page_dir_slot_set_rec().
Improve the documentation of the page_zip parameters in page0page.
Add function page_trailer_get_len().
Implement page_zip_write_header().
Add page_zip parameter to btr_page_set_ functions.
Allow page_copy_rec_list_end() to be called with invalid new_page_zip
if the page has been newly created.
