Hi!
InnoDB is the MySQL table type that supports foreign keys, transactions,
non-escalating row-level locking, all SQL-92 transaction isolation levels,
multiversion concurrency control, savepoints, multiple tablespaces, and a
non-free online binary hot backup tool.
MySQL-4.1.10 is mainly a bugfix release.
Windows users of the my.cnf option innodb_file_per_table should upgrade to
this version, because this fixes the bug introduced to the Windows version
of 4.1.9, and earlier versions contained the critical bug in
innodb_file_per_table.
Functionality added or changed:
* When MySQL/InnoDB is compiled on Mac OS X 10.2 or earlier, detect the
operating system version at run time and use the fcntl() file flush method
on Mac OS X versions 10.3 and later. Apple had disabled fsync() in Mac OS X
for internal disk drives, which caused corruption at power outages.
* A shared record lock LOCK_REC_NOT_GAP is now taken for a matching record
in the foreign key check because inserts can be allowed into gaps.
* Relaxed locking in INSERT...SELECT, single table UPDATE...SELECT and
single table DELETE...SELECT clauses when innobase_locks_unsafe_for_binlog
is used and isolation level of the transaction is not serializable. InnoDB
uses consistent read in these cases for a selected table.
Bugs fixed:
* Fixed a bug introduced in 4.1.9 to the Windows version if you used
innodb_file_per_table. mysqld would stop and complain about Windows error
number 87 in a file operation. (Bug #8021)
* Corrected the handling of trailing spaces in the ucs2 character set. (Bug
#7350)
* Use native tmpfile() function on Netware. All InnoDB temporary files are
created under sys:\tmp. Previously, InnoDB temporary files were never
deleted on Netware.
* Fix a race condition that could cause the assertion
space->n_pending_flushes == 0 to fail in fil0fil.c, in
@(protected){fil_space_free()}, in DROP TABLE or in ALTER TABLE.
* ALTER TABLE ... ADD CONSTRAINT PRIMARY KEY ... complained about bad
foreign key definition. (Bug #7831)
* Fix a theoretical hang over the adaptive hash latch in InnoDB if one runs
INSERT ... SELECT ... (binlog not enabled), or a multi-table UPDATE or
DELETE, and only the read tables are InnoDB type, the rest are MyISAM. (Bug
#7879)
Upgrading to 4.1.9:
* If you have created or used InnoDB tables with TIMESTAMP columns in MySQL
versions 4.1.0-4.1.3, you have to rebuild those tables when you upgrade to
MySQL-4.1.4 or later. The storage format in those MySQL versions for a
TIMESTAMP column was wrong. If you upgrade from 4.0 to 4.1.4 or later, then
no rebuild of TIMESTAMP tables is needed.
* If you have stored characters < ASCII(32) to non-latin1 non-BINARY indexed
columns in MySQL versions <= 4.1.2, then you have to rebuild those tables
after you upgrade to >= 4.1.3. The reason is that the sorting order of those
characters and the space character changes for some character sets in 4.1.3.
See the MySQL/InnoDB-4.1.3 changelog for a precise description of the cases
where you need to rebuild the table. Also MyISAM tables have to be rebuilt
or repaired in these cases.
* If you have used column prefix indexes on UTF-8 columns or other multibyte
character set columns in 4.1.0 - 4.1.5, you have to rebuild the tables when
you upgrade to 4.1.6 or later.
* If you have used accent characters (ASCII codes >= 128) in database names,
table names, constraint names, or column names in versions < 4.1, you cannot
upgrade to 4.1 directly, because 4.1 uses UTF-8 to store metadata names. Use
RENAME TABLE to overcome this if the accent character is in the table name
or the database name, or rebuild the table.
