plugin "InnoDB", not "InnoDBzip".

We can disable the builtin InnoDB by mysqld --skip-innodb.  If the
builtin InnoDB is not disabled, installing the InnoDB plugin by the same
name will not work.

innodb_plugin_init(): Ignore differences in the PLUGIN_VAR_READONLY flag.

ha_innobase::write_row(): The printf format %p expects const void*.

STRUCT_FLD: Do not use the GCC extension when __STRICT_ANSI__ is defined.

row_merge_read_clustered_index(): Compound initializers must not contain
variables.  Assign to struct fields instead.

initialized, although Valgrind believes that some bits in the 7th or 8th
bytes from the end are uninitialized.  (They might be, but the decompressor
should not care about those bits after encountering the end-of-stream marker
in the compressed bit stream.)

btr_cur_optimistic_insert(): On compressed tablespaces, check that both
the compressed and the uncompressed page are completely initialized in
the beginning of the function.

page_zip_compress(): After successful compression, check that the compressed
page is completely initialized.

page_zip_write_rec(), page_zip_write_blob_ptr(), page_zip_write_node_ptr(),
page_zip_write_trx_id_and_roll_ptr(), page_zip_clear_rec(),
page_zip_rec_set_deleted(), page_zip_rec_set_owned(), page_zip_dir_insert(),
page_zip_dir_delete(), page_zip_dir_add_slot(), page_zip_reorganize(),
page_zip_copy(), page_zip_get_trailer_len(), page_zip_write_header():
Assert that the complete contents of the compressed page is defined.

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.

Use UNIV_MEM_ASSERT_RW() instead of UNIV_MEM_VALID().  The latter
flags memory defined; the former checks that it is defined.

instrumentation.

Remove the Valgrind check about it.

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.

trx_rollback_or_clean_all_recovered().

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.

trx_commit_for_mysql().

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.

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.

to the time in which modern disks can serve a random disk read.

wait_until_unfixed.

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.

Make lock_get_type_str() to also indicate if it is a gap lock.

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.

dfield_dup(): New function for duplicating the data pointed to by dfield_t.

dfield_set_len(), dfield_set_data(): Add Valgrind instrumentation.

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 (;;).

btr_pcur_get_rel_pos(): Add a const qualifier.

btr_pcur_get_btr_cur(), btr_pcur_get_page_cur(): btr_cur_get_page_cur():
Define as const-preserving macros.

btr_pcur_is_on_user_rec(), btr_pcur_is_after_last_on_page(),
btr_pcur_is_before_first_on_page(): Remove the unused parameter mtr.
Add a const qualifier.

btr_pcur_move_to_next_on_page(), btr_pcur_move_to_prev_on_page():
Remove the unused parameter mtr.

page_cur_search(): Add const qualifiers.

page_cur_get_page(), page_cur_is_before_first(), page_cur_is_after_last():
Add debug assertions.
