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().
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.
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.
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.
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.
for more accurate Valgrind debugging.
univ.i: Introduce UNIV_DEBUG_VALGRIND, UNIV_MEM_VALID, and UNIV_MEM_INVALID.
buf_LRU_block_free_non_file_page(): Invalidate the buffer frame
with UNIV_MEM_INVALID().
buf_LRU_get_free_block(): Declare the buffer frame valid
with UNIV_MEM_VALID().
Other memory is allocated and deallocated via malloc() and free(),
which are already overridden by Valgrind. Without the added
instrumentation, accesses to free pages in the buffer pool cannot
be caught.
The diagnostics could probably be improved further by declaring all
non-latched buffer frames invalid.
buf_LRU_get_free_block(): When zip_size changes, initialize all fields
of page_zip. This avoids an assertion failure in page_create_zip() when
a block with an originally larger zip_size is reallocated.
fsp_get_space_header(): Assert that the stored space id matches.
xdes_get_state(): Assert that the state is valid.
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.
