page_zip_compress(): Assert that the contents of the uncompressed page
is entirely initialized.
page_zip_decompress(): Assert that the contents of the compressed page
is entirely initialized. Assert that the uncompressed page is entirely
writeable. Flag the uncompressed page uninitialized in the beginning.
buf_buddy_relocate(): Allow the source block to contain uninitialized data.
buf0buddy.c: Replace the remaining VALGRIND_CHECK_ macros with the wrappers
defined in univ.i.
buf_LRU_free_block(): Check that the block descriptor contains valid data.
buf_buddy_relocate(): Check that the source block contains valid data.
buf_page_get_gen(): Do not dereference bpage after calling buf_relocate().
This avoids a bogus Valgrind warning; the memory itself was valid.
buf_page_hash_get(): Check that the returned block descriptor contains
valid data.
recovered transactions from new ones. Until r1594, they were distinguished
by trx->sess == NULL.
trx_t: Add the bitfield is_recovered.
trx_lists_init_at_db_start(): Set trx->is_recovered.
trx_create(): Initialize trx->is_recovered = 0.
trx_print(): Display information about trx->is_recovered.
trx_rollback_or_clean_all_without_sess(): Skip new transactions.
Protect all accesses of trx_sys->trx_list with kernel_mutex.
trx_roll_crash_recv_trx, trx_roll_max_undo_no, trx_roll_progress_printed_pct:
Made these variables static.
Add innodb_locks.lock_data column and some relevant tests.
For record locks this column represents the ordering fields of the
locked row in a human readable, SQL-valid, format.

on mispredicted branches: opcontrol --event=BR_CND_MISSP_EXEC:45000
UT_SORT_FUNCTION_BODY(): Copy the array with memcpy(3).
cmp_dtuple_rec_with_match(), cmp_rec_rec_with_match(),
cmp_debug_dtuple_rec_with_match(): Add UNIV_UNLIKELY hints around
tests for REC_INFO_MIN_REC_FLAG.
Change mach_read_int_type() to return an integer type (ullint) instead
of array of bytes that later needs to be converted to an appropriate
integer type.

log_block_calc_checksum(), log_block_get_checksum(): Add const qualifiers.
log_block_calc_checksum(): Split a long expression to more readable chunks.
Some compilers might optimize this better.
srv_print_thread_releases, srv_print_lock_waits, srv_print_buf_io,
srv_print_log_io, srv_print_latch_waits: Define these variables as
constants (FALSE), unless UNIV_DEBUG is defined. These variables
are never assigned to, and they are initialized to FALSE. It could
be useful to set them when debugging InnoDB.
srv_slot_t: Fuse the fields type, in_use, suspended to a single machine word.
srv_meter[], srv_meter_low_water[], srv_meter_high_water[],
srv_meter_high_water2[], srv_meter_foreground[]: Enclose these arrays
inside #if 0. The arrays are essentially constants that do not affect
the control flow.
enum srv_thread_type: New enum, to replace the #defines SRV_COM, ...
Enclose the unused values SRV_BUFFER, SRV_RECOVERY, SRV_INSERT
inside #if 0, so that some arrays and loops can be reduced.
row_upd_rec_in_place(): Correct a debug assertion.
row_upd_index_parse(): Initialize new_val with dfield_set_data() or
dfield_set_null(). This ensures that new_val->ext is initialized.
value of the block that the cursor points to.
row_ins_check_foreign_constraint(): Call btr_pcur_get_block() after
row_ins_foreign_check_on_constraint(), as it may reposition the cursor
on a different page.
row_ins_scan_sec_index_for_duplicate(): Call btr_pcur_get_block() on
every iteration of the loop. Use do ... while instead of for (;;).
enum trx_dict_op: dictionary operation modes
trx_get_dict_operation(), trx_set_dict_operation(): Accessors for
trx->dict_operation.
lock_table_enqueue_waiting(), lock_rec_enqueue_waiting(): Do not complain
about lock waits if the dictionary mode is TRX_DICT_OP_INDEX_MAY_WAIT.
row_merge_lock_table(): Remove the work-around for avoiding the warning
in lock_table_enqueue_waiting().
trx_undo_mark_as_dict_operation(): Do not write trx->table_id to the
undo log unless the dict_operation is TRX_DICT_OP_TABLE.
ha_innobase::add_index(): Set the dict_operation mode initially to
TRX_DICT_OP_INDEX_MAY_WAIT, then lock the table exclusively, and set the
mode to TRX_DICT_OP_INDEX, and optionally to TRX_DICT_OP_TABLE when
creating a temporary table.
page_cur_set_before_first(), page_cur_set_after_last(),
page_cur_position(): Add const qualifiers to buf_block_t and rec.
A better solution would be to define a const_page_cur_t and a
set of accessors, but it would lead to severe code duplication.
page_rec_get_n_recs_before(): Add const qualifiers.
page_dir_get_nth_slot(): Define as a const-preserving macro.
page_dir_slot_get_rec(), page_dir_slot_get_n_owned(),
page_dir_find_owner_slot(), page_check_dir(): Add const qualifiers.
page_rec_get_next_low(): Add const qualifiers.
page_rec_get_next_const(), page_rec_get_prev_const(): New functions,
based on the const-less page_rec_get_next() and page_rec_get_prev().
page_cur_get_page(), page_cur_get_block(), page_cur_get_page_zip(),
page_cur_get_rec(): Define as const-preserving macros.
page_cur_try_search_shortcut(), page_cur_search_with_match():
Add const qualifiers.
buf_page_get_mutex(): Add a const qualifier to buf_page_t*.
rec_get_next_ptr_const(): Const variant of rec_get_next_ptr().
The size of the buffer pool can be one page smaller than the requested
size when os_mem_alloc_large() returns something that is not
aligned by UNIV_PAGE_SIZE. This test may still fail on systems with
a big os_large_page_size.
fix the bugs introduced in r1591.
row_rec_to_index_entry_low(): Clear "n_ext". Do not allow it to be NULL.
Add const qualifier to dict_index_t*.
row_rec_to_index_entry(): Add the parameters "offsets" and "n_ext".
btr_cur_optimistic_update(): Add an assertion that there are no externally
stored columns. Remove the unreachable call to btr_cur_unmark_extern_fields()
and the preceding unnecessary call to rec_get_offsets().
btr_push_update_extern_fields(): Remove the parameters index, offsets.
Only report the additional externally stored columns of the update vector.
row_build(), trx_undo_rec_get_partial_row(): Flag externally stored columns
also with dfield_set_ext().
rec_copy_prefix_to_dtuple(): Assert that there are no externally stored
columns in the prefix.
row_build_row_ref(): Note and assert that the index is a secondary index,
and assert that there are no externally stored columns.
row_build_row_ref_fast(): Assert that there are no externally stored columns.
rec_offs_get_n_alloc(): Expose the function.
row_build_row_ref_in_tuple(): Assert that there are no externally stored
columns in a record of a secondary index.
row_build_row_ref_from_row(): Assert that there are no externally stored
columns.
row_upd_check_references_constraints(): Add the parameter offsets, to
avoid a redundant call to rec_get_offsets().
row_upd_del_mark_clust_rec(): Add the parameter offsets. Remove
duplicated code.
row_ins_index_entry_set_vals(): Copy the external storage flag.
sel_pop_prefetched_row(): Assert that there are no externally stored
columns.
row_scan_and_check_index(): Copy offsets to a temporary heap across
the invocation of row_rec_to_index_entry().
and use it for flagging externally stored columns in the data tuple.
The data tuple contains the same columns as the clustered index record,
but in a different order. This error was introduced in r1591.
TODO: the assertion ut_ad(!dfield_is_ext()) may fail in
btr_cur_pessimistic_update().
