5fc003b65d branches/zip: Make mutex_own() work with UNIV_DEBUG, without UNIV_SYNC_DEBUG. 2007-01-18 18:29:12 +00:00

f116afa724 branches/zip: Remove the fil_space_get_zip_size() call from 
buf_page_get_gen().  This saves one mutex operation per block request.

buf_page_get_gen(), various macros and functions: Add parameter zip_size.

btr_node_ptr_get_child(): Add parameter index.

fil_space_get_latch(): Add optional output parameter zip_size.

fil_space_get_zip_size(): Return 0 for space id==0, because the
system tablespace is never compressed.

fsp_header_init(): Remove the parameter zip_size.

ibuf_free_excess_pages(): Remove the parameter zip_size.

trx_rseg_t, trx_undo_t: Add field zip_size.

xdes_lst_get_next(): Remove, unused.

5669dc3d2a branches/zip: Reduce the number of buf_block_align() calls. 
btr_block_get(): New function to return buf_block_t.

btr_page_alloc(), buf_page_get_release_on_io(), buf_page_get_gen(),
buf_page_create(), fseg_create(), fseg_create_general(): Return buf_block_t.

buf_page_get_known_nowait(): Expect buf_block_t instead of buf_frame_t.

buf_frame_get_newest_modification(): Replace with
buf_block_get_newest_modification().

buf_page_dbg_add_level(): Replace with buf_block_dbg_add_level().

buf_block_get_zip_size(): New function.

buf_block_get_page_zip(): Reintroduce.

recv_recover_page(): Replace page, space, page_no with block.

ibuf_bitmap_page_init(): Replace page, zip_size with block.

ibuf_parse_bitmap_init(): Remove the parameter zip_size.

btr_search_drop_page_hash_index(): Replace page with block.

4465e272a0 branches/zip: Allow the code to be built with function inlining enabled. 
page0page.h: Add #include "page0zip.h"

page_dir_slot_get_rec(): Avoid void* arithmetics.

trx0undo.ic, trx0sys.ic: Remove unnecessary #include "page0zip.h"

page_zip_write_header(): Move prototype from page0types.h to page0zip.h

12050c5c1c branches/zip: Prepare for in-place updates of B-tree node pointers, 
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.
