LAST FOREIGN KEY ERROR section in SHOW INNODB STATUS output (Bug #16814).
dict_foreign_error_report(): Always print a newline after invoking
dict_print_info_on_foreign_key_in_create_format().
that were not part of r154. (Bug #3300)
innodb.test, innodb.result: Remove binlog related tests, because they
are not InnoDB specific; they merely require a transactional table.
ha_innobase::ha_innobase(): Add HA_PRIMARY_KEY_ALLOW_RANDOM_ACCESS
to table_flags.
ha_innobase::rnd_init(): Disable semi-consistent read for random access.
of breaking serializability. (Bug #3300)
ha_innobase::unlock_row(): reset the "did semi consistent read" flag
ha_innobase::was_semi_consistent_read(),
ha_innobase::try_semi_consistent_read(): new methods
row_prebuilt_t, row_create_prebuilt(): add field row_read_type for
keeping track of semi-consistent reads
row_vers_build_for_semi_consistent_read(),
row_sel_build_committed_vers_for_mysql(): new functions
row_search_for_mysql(): implement semi-consistent reads
adaptive hash index for a B-tree page. (Bug #16582)
btr_search_drop_page_hash_index(): Retry the operation if a hash index
with different parameters was built meanwhile. Add diagnostics for the
case that hash node pointers to the page remain. This fix is from Heikki.
btr_search_info_update_hash(), btr_search_info_update_slow():
Document the parameter "info" as in/out.
Keep track on unflushed modifications to file spaces. When there are tens
of thousands of file spaces, flushing all files in fil_flush_file_spaces()
would be very slow. (Bug #15653)
fil_flush_file_spaces(): Only flush unflushed file spaces.
fil_space_t, fil_system_t: Add a list of unflushed spaces.

Make innodb_thread_concurrency 0 by default, and extend the useable
range from 0 to 1000 (0 disables the thread throttling).
Remove SRV_CONCURRENCY_THRESHOLD (20). The magic value to
disable the thread throttling is 0 from now on.
Do not mistake TABLENAME_ibfk_0 for auto-generated id (Bug #16387).
dict_table_get_highest_foreign_id(): Ignore foreign constraint identifiers
starting with the pattern TABLENAME_ibfk_0.
innodb.test, innodb.result: Add test case.
Fixed a bug #16229 MySQL/InnoDB uses full explicit table locks
in trigger processing. Take a InnoDB table lock only if user has explicitly
requested a table lock. Added some additional comments to store_lock() and
external_lock(). Added test cases for a bug. Fixed some code style errors.
dict_load_columns(): Set the charset-collation code
DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns
that lack a charset-collation code, i.e., the tables were created
with an older version of MySQL/InnoDB than 4.1.2. (Bug #16298)
lock_rec_unlock(): Initialize local variable release_lock, in order to avoid
dereferencing an uninitialized pointer when no lock exists on rec.
This bug was introduced in r103 of branches/5.0, ported as r104 to trunk.
os_file_handle_error(): Map the error codes EXDEV, ENOTDIR, and EISDIR
to the new code OS_FILE_PATH_ERROR. Treat this code as OS_FILE_PATH_ERROR.
This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link
to a different file system. (Bug #15991)
Fix for BUG#11704: "Found locks from different thread" warnings:
The source of warnings was this scenario in OPTIMIZE:
thr1: lock table with TL_WRITE_ONLY (InnoDB converts lock to
TL_WRITE_ALLOW_WRITE)
thr2: (UPDATE command) obtains a TL_WRITE_ALLOW_WRITE lock
thr1: call mysql_lock_abort(). This function sets type of thr'1 lock
to TL_WRITE_ONLY
thr2: try to release thr2's lock. See two locks: TL_WRITE_ONLY,
TL_WRITE_ALLOW_WRITE and produce a warning.
The fix: Make InnoDB not to convert TL_WRITE_ONLY locks to
TL_WRITE_ALLOW_WRITE in OPTIMIZE TABLE.
Do not pad VARBINARY or BINARY columns. (Bug #14189)
innodb.test, innodb.result: Add test cases for foreign key constraints
between VARBINARY and BINARY columns, and between VARCHAR BINARY and
CHAR BINARY columns.
innobase_init(): Assert that
DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number.
dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns.
row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE
when trying to change the length of a VARBINARY column
that refers to or is referenced by a BINARY column. BINARY
columns are no longer padded on comparison, and thus they
cannot be padded on storage either.
In row_ins_set_detailed(), truncate the tmpfile by os_file_set_eof(), because
trx_set_detailed_error_from_file() does not call ftell() to determine
the actual length of the file. This bug resulted in trash being appended
to foreign key error messages.
