and add assertions to callers. Remove the added ibool* parameter and
return enum row_search_result instead of ibool, to reflect the four
different outcomes: record found, not found, buffered, and status unknown
(record not in the buffer pool).
rb://6
This function was created when the delete buffering code was merged from
branches/fts in r2324.
ibuf_rec_get_size(): Rename the parameter new_format to pre_4_1. Use
the correct offsets and accessors for both values of pre_4_1.
ibuf_rec_get_info(): Note that the record must be in 4.1 or later format.
ibuf_get_entry_counter_low(): Rename from ibuf_set_entry_counter_low().
This function only reads the counter. Add const qualifier to the
rec parameter.
ibuf_set_entry_counter(): Document the entry parameter as in/out.
ibuf_rec_get_info(): Eliminate the local variable "mod". Use switch-case
instead of if-else if-else.
ibuf_rec_get_op_type(), ibuf_add_ops(), ibuf_print_ops():
Add const qualifiers to read-only parameters.
ibuf_rec_get_volume(): Remove empty line at end of block.
error. In r2324, when changes were merged from branches/fts, the
assignment guess = NULL was accidentally removed after height--.
The assignment is in that place in branches/fts since r990.
flag to row_search_index_entry() when there are no foreign key
constraints. This flag was accidentally omitted when the delete buffering
was merged from branches/fts in r2324, and thus delete marking was never
buffered.
buf_pool->watch_ fields to start with the common prefix buf_pool_watch,
so that they can be searched easily:
buf_pool_watch_set(): Renamed from buf_pool_add_watch(). The "add" was
misleading, because only one watch can be active at a time.
buf_pool_watch_clear(): Renamed from buf_pool_remove_watch().
buf_pool_watch_occurred(): Renamed from buf_pool_watch_happened().
buf_page_get_gen(): Once again, zip_size must always match the
compressed page size of the tablespace where the page is requested from.
This seems to hold also for all calls from the insert buffer.
buf_page_optimistic_get_func(): Do not pass mtr to ibuf_page(), because
there is no guarantee that mtr would contain an x-latch to the insert
buffer bitmap page that covers (block->page.space, block->page.offset).
zip_size should always equal fil_space_get_zip_size(space), even when called
from ibuf.
ibuf_page() should be called with mtr=NULL to be equivalent to the original
implementation. We cannot assume that mtr holds an x-latch on the insert
buffer bitmap page that covers the page that is being requested.
differences from branches/zip. The __attribute__((unused)) should
work on all platforms. When compiled with something else than GCC,
MySQL supposedly does #define __attribute__(x) /* empty */
so that the attributes will be ignored.
from branches/zip.
btr_cur_optimistic_delete(): Split a too long line in the way it is
split in branches/zip.
buf_page_get_gen(): Add missing space in the function comment.
buf_print_io(): Restoer a removed space to the printout.
univ.i: Remove C++-style (or C99-style) comments.
buf0buf.h: Undo the white-space changes to the wrapper macros of
buf_page_get_gen().
ibuf_update_free_bits_low(): Revert the changes. Restore the assertion
that this function must not be invoked on compressed pages. The function
ibuf_update_free_bits_zip() is for compressed pages.
ibuf_insert_to_index_page(): Undo a white-space change.
btr0cur.c: Undo changes to white space that make the code differ from
branches/zip.
btr_cur_del_unmark_for_ibuf(): Remove this unused function.
btr_cur_set_deleted_flag_for_ibuf(): Add missing UNIV_INTERN specifier.
Correct the function comment. Call btr_rec_set_deleted_flag() instead
of rec_set_deleted_flag_new(), so that delete buffering will actually
work on ROW_FORMAT=REDUNDANT tables.
closer to branches/zip.
ibuf_size_update(): Add const qualifier to the parameter "root".
Remove #ifdef UNIV_SYNC_DEBUG around ut_ad(mutex_own()).
ibuf_page(): Use the variable name local_mtr instead of mtr_local, to
be more like existing functions. Eliminate the flag use_local_mtr.
ibuf_get_merge_page_nos(): Restore an "if (...) break; else if" to
"if (...) break; if" as in branches/zip.
ibuf_dummy_index_create(), ibuf_dummy_index_add_col(),
ibuf_contract_ext(), ibuf_insert_low(): Revert to the formatting of
branches/zip.
