ibuf_reset_free_bits(): Remove, as there already is a similar function
ibuf_reset_free_bits_with_type().
ibuf_reset_free_bits_with_type(), ibuf_set_free_bits(),
ibuf_update_free_bits_if_full(), btr_leaf_page_release(),
buf_page_make_young(): Replace page_t with buf_block_t.
btr_compress(): Replace btr_page_get() with btr_block_get().
with page_get_page_no() and page_get_space_id(). We want to avoid
buf_block_align() calls, and the page_no and space_id are now stamped
on the pages early on.
dict_load_foreigns(): Enclose in #ifndef UNIV_HOTBACKUP.
fil_extend_tablespaces_to_stored_len(): Pass zip_size to fil_read().
buf_page_init_for_backup_restore(): Add parameter zip_size.
Enclose the declaration in buf0buf.h in #ifdef UNIV_HOTBACKUP.
recv_apply_log_recs_for_backup(): Replace the local variable "page"
with the local variable "block". Add local variable zip_size.
Introduce FIL_PAGE_ZBLOB_DATA as a synonym for FIL_PAGE_FILE_FLUSH_LSN.
btr_store_big_rec_extern_fields(): Make the assertion about
dict_table_zip_size() more accurate.
buf_LRU_get_free_block(), buf_block_alloc(): Add parameter zip_size.
buf_calc_zblob_page_checksum(): Remove. Replace with page_zip_calc_checksum().
buf_page_init(): Remove parameter zip_size.
buf_page_io_complete(): Add a placeholder for handling compressed pages.
trx_doublewrite_page_inside(): Remove redundant function.
page_zip_write_rec(): Relax an overly tight assertion about blob_no.
buf_page_print(): Print also compressed pages. Add parameter zip_size.
buf_flush_init_for_writing(): Stamp the fields on a compressed B-tree index
page.
Add the header field FIL_PAGE_ZBLOB_SPACE_ID as an alias of FIL_PAGE_PREV.
page_zip_calc_checksum(): New function.
page_zip_compress(): Avoid copying the fields that are written in
buf_flush_init_for_writing().
page_zip_header_cmp(): New function for comparing those fields of the
page header that will not be written in buf_flush_init_for_writing().
btr_page_reorganize_low(): Rename new_page to temp_page.
btr_store_big_rec_extern_fields(): FIL_PAGE_TYPE is 2 bytes, not 4.
buf_page_init(), buf_page_create(), buf_read_page_low(),
buf_page_init_for_read(): Add parameter zip_size.
buf_page_init_for_backup_restore(),
recv_apply_log_recs_for_backup(): Enclose in #ifdef UNIV_HOTBACKUP.
Enclose some debug code in #ifdef UNIV_LOG_REPLICATE.
page_zip_write_header_log(): Replace page_zip with a pointer to
the uncompressed page.
page_zip_write_rec(): Relax an assertion about blob_no + n_ext.
page_copy_rec_list_to_created_page_write_log(): Allow logging to be disabled.
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.
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.
