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.
fil_read(), fil_write(): Make these inlined functions in fil0fil.c.
fil_write_lsn_and_arch_no_to_file(): Remove the parameter space_id and
note that this function is to be called on the system tablespace, which
is uncompressed.
os_aio_simulated_handle(): Temporarily disable os_file_check_page_trailers(),
which cannot be invoked on compressed pages.
dict_table_add_system_columns(): New function, split from
dict_table_add_to_cache().
mlog_parse_index(): Add system columns to the dummy table and identify
DB_TRX_ID and DB_ROLL_PTR in the dummy index.
buf_LRU_get_free_block(): Note that page_zip->data should be allocated from
an aligned memory pool.
buf_flush_buffered_writes(): Write compressed pages to disk.
buf_flush_post_to_doublewrite_buf(): Copy compressed pages to the
doublewrite buffer. Zero fill any excess space.
buf_flush_init_for_writing(): Treat all compressed pages the same.
buf_read_page_low(): Read compressed pages from disk.
buf_page_io_complete(): Process compressed pages.
trx_sys_doublewrite_init_or_restore_page(): Process compressed pages.
mlog_write_initial_log_record_fast(): Enable a debug printout
#ifdef UNIV_LOG_DEBUG.
fsp_header_init(), fsp_fill_free_list(): Pass the compressed page size
to buf_page_create().
page_zip_compress_write_log(): Flatten the if-else if-else logic.
page_zip_parse_write_blob_ptr(): Do not test page_zip if page==NULL.
page_zip_parse_write_node_ptr(): Do not test page_zip if page==NULL.
Invoke mlog_close() correctly.
row_sel_store_row_id_to_prebuilt(): Add UNIV_UNLIKELY hint to an
assertion-like test.
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().
buf_flush_init_for_writing(): Calculate the checksum with the actual zip_size.
buf_calc_zblob_page_checksum(): Skip the field FIL_PAGE_SPACE_OR_CHKSUM.
trx_sys_doublewrite_init_or_restore_page(): Use the actual zip_size.
page_cur_insert_rec_low(): If page_zip_alloc() fails, try compressing the
whole page afterwards.
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.
