buf_pool_t: Remove n_frames, max_size, and blocks_of_frames.
The current buffer pool size is in curr_size.
buf_pool_init(): Remove parameter max_size.
buf_pool_get_max_size(), buf_pool_is_block(): Remove.
buf_block_align(): Do not assume that the buffer pool is allocated
in one chunk. Replace dependency on buf_pool->blocks_of_frames
with a call to buf_page_hash_get().
Do not break the latching order in TRUNCATE TABLE.
dict_truncate_index_tree(): Replace parameter rec_t* rec with
btr_pcur_t* pcur. Reposition pcur before calling btr_create().
sync_thread_add_level(): Remove the relaxation of the assertion added in r968.
btr_pcur_restore_position(): Add const qualifiers.
buf_LRU_block_remove_hashed_page(): Reduce the amount
of buf_page_hash_get() calls and add a UNIV_UNLIKELY hint
to an assertion-like test.
rec_get_nth_field_offs_old(): Split from rec_get_nth_field_old().
rec_get_nth_field_old(): Reimplement as a constness-preserving macro.
dict_drop_index_tree(), dict_truncate_index_tree(): Note that rec is
an in/out parameter, as the B-tree root page number will be updated.
buf0lru.c: Always #include "srv0srv.h"
buf_block_get_lock_mutex(), buf_frame_get_lock_mutex(): Remove.
mtr0log.ic: Remove #include "page0page.h" and replace the page_
functions with lower-level ones to break an #include cycle.
dict0dict.ic: Remove unnecessary #include "trx0undo.h" and "trx0sys.h"
that would create an #include cycle.
btr_check_node_ptr(): Replace page_t* parameter with buf_block_t*.
btr_free_externally_stored_field(): Add const qualifier to rec.
Remove an explicit buf_block_align() call, but replace an
mtr_memo_contains() with mtr_memo_contains_page().
row_upd_rec_sys_fields(): Reorder an assertion containing buf_block_align()
so that the costly call can be avoided in some cases.
from the adaptive hash index [btr_search_guess_on_hash() and
btr_search_validate()]. Some references to buf_block_align() remain
in debug builds.
btr_store_big_rec_extern_fields(): Add the parameter rec_block.
page_rec_get_next_low(): Do not assume that the page has been
allocated from the buffer pool when printing the diagnostic information.
page_cur_insert_rec_low(): Replace the parameter page_zip_des_t* page_zip
with the parameter buf_block_t* block.
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.
Replace buf_frame_t* guess with buf_block_t* guess in order to avoid
a buf_block_align() call.
trx_undo_t: Replace page_t* guess_page with buf_block_t* guess_block.
btr_search_t: Replace page_t* root_guess with buf_block_t* root_guess.
page_set_max_trx_id(): Replace page_t* parameter with buf_block_t*,
to avoid a buf_block_align() call.
Replace some occurrences of page_get_page_no() with buf_block_get_page_no().
page_cur_delete_rec(): Replace buf_block_align() with page_cur_get_block().
btr_cur_pessimistic_insert(): Remove local variable "block". Replace
an extraneous call to btr_cur_position() [with wrong "block", in r948]
with a debug assertion that the cursor is positioned on the preceding
record after the page split.
btr_pcur_restore_position(): Do not use btr_pcur_get_page(), because
the debug assertion there could fail. This bug was introduced in r928.
btr_cur_t: Move page_block to page_cur_t::block.
page_cur_get_block(), page_cur_get_page_zip(): New functions.
page_cur_position(): Add parameter block.
Remove many page_zip parameters, now that there is page_cur_get_page_zip().
Replace some page, page_zip parameters with block.
Add some const qualifiers to function parameters and remove casts.
PAGE_HEAP_NO_INFIMUM, PAGE_HEAP_NO_SUPREMUM, PAGE_HEAP_NO_USER_LOW:
New constants.
Replace some cursor code in low-level diagnostic functions with
direct management of rec, because buf_block_t::buf_fix_count may be 0
when the functions are called, and debug assertions would fail.
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.
passed as TRUE.
Enclose hash_table_t::adaptive and buf_block_t::n_pointers in
#ifdef UNIV_DEBUG.
btr_search_drop_page_hash_index(): Enclose the corruption check
(which depends on buf_block_t::n_pointers) in #ifdef UNIV_DEBUG.
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.
the symbol UNIV_DEBUG_PRINT, which was introduced in r729.
buf_LRU_print(), buf_print(): Replace #ifdef UNIV_DEBUG_PRINT
with #if defined UNIV_DEBUG || defined UNIV_DEBUG_PRINT.
