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.

ba1fb95598 branches/zip: Try to adhere to ISO 9899:1989 where possible. (The recently
introduced ib_longlong and %ll length specifier are not C89.)

row_ext_t: Change char* buf to byte* buf to avoid signedness warnings.

Change the type of all bit fields to unsigned.

rec_get_next_ptr(): Add (byte*) casts to avoid arithmetics on void*.

page_zip_decompress_clust(): Do not mix declarations and code.

aedce8cde3 branches/zip: Move the fields related to the least-recently-used algorithm
of the buffer pool from buf_block_t to buf_page_t.  Replace some buf_block_t*
parameters with buf_page_t*.  Add accessor functions.

marko
329a29c2fb branches/zip: Replace ib_ulonglong with ib_uint64_t, since we want exactly
64 bits.  "long long" might be longer than 64 bits on some systems.
2006-11-29 14:52:16 +00:00
marko
7593a465db branches/zip: Introduce the unsigned 64-bit data type ib_ulonglong
for log sequence numbers, to replace dulint.

marko
c1ffbbd90f branches/zip: Remove all references to buf_block_align() except those
from the adaptive hash index [btr_search_guess_on_hash() and
btr_search_validate()].  Some references to buf_block_align() remain
in debug builds.

438cb8a6c1 branches/zip: Remove all buf_block_align() calls from lock0lock.c.
Replace all page_t* parameters with buf_block_t*, and replace many
rec_t* parameters with heap_no.  This eliminates also many
rec_get_heap_no() calls, which became more expensive with the
introduction of ROW_FORMAT=COMPACT in MySQL/InnoDB 5.0.3.

page_rec_get_heap_no(), lock_get_min_heap_no(): New functions.

fbe4fe6022 branches/zip: Remove the casts introduced in r920 and r925. Replace the
accessors returning pointers with macros that preserve const qualifiers.
In UNIV_DEBUG builds, retain the accessors and cast away constness there.

dfield_get_type(), dfield_get_data(), dtuple_get_nth_field(),
dict_table_get_nth_col(), dict_table_get_sys_col(): Implement as macro
unless #ifdef UNIV_DEBUG.

rec_get_nth_field(): Replace with rec_get_nth_field_offs() that does not
do pointer arithmetics.  Implement rec_get_nth_field() as a macro.

8f07794024 branches/zip: Introduce const qualifiers to many read-only parameters
and modify some functions to return const pointers.  Add const qualifiers
to local variable declarations or casts to remove the const qualifier
in those places where write access is needed.

736a8ffb01 branches/zip: Replace buf_frame_get_page_no() and buf_frame_get_space_id()
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.

174bd7b7ca branches/zip: dtuple_convert_big_rec(): Do not store anything locally
of externally stored columns, and fix bugs introduced in r873.  (Bug #22496)

btr_page_get_sure_split_rec(), btr_page_insert_fits(),
rec_get_converted_size(), rec_convert_dtuple_to_rec(),
rec_convert_dtuple_to_rec_old(), rec_convert_dtuple_to_rec_new():
Add parameters ext and n_ext.  Flag external fields during the
conversion.

rec_set_field_extern_bits(), rec_set_field_extern_bits_new(),
rec_offs_set_nth_extern(), rec_set_nth_field_extern_bit_old():
Remove.  The bits are set by rec_convert_dtuple_to_rec().

page_cur_insert_rec_low(): Remove the parameters ext and n_ext.

btr_cur_add_ext(): New utility function for updating and sorting ext[].
Low-level functions now expect the array to be in ascending order
for performance reasons.  Used in btr_cur_optimistic_insert(),

btr_cur_optimistic_insert(): Remove some defensive code, because we cannot
compute the added parameters of rec_get_converted_size().

be twice the maximum usage, so that ut_ulint_sort() can be used.

dtuple_convert_big_rec(): Allocate new space for the BLOB pointer,
to avoid overwriting prefix indexes to the same column.  Adapt
dtuple_convert_back_big_rec().

row_build_index_entry(): Fetch the columns also for prefix indexes of
the clustered index.

stored fields to lack a locally stored part.

marko
16a5b78833 branches/zip: row_build_index_entry(): Fix errors introduced in r870.
Do not augment clustered index records.  When computing the prefix,
use dfield (where the prefix was copied), not dfield2 (the record in
the clustered index).

marko

btr_copy_externally_stored_field(): Split to
btr_copy_externally_stored_field_prefix_low().

8e59e994ac branches/zip: Minor cleanup in update related code.
