MySQL Reference Manual for version 4.0.18.
14.4.16.30 MySQL/InnoDB-3.23.48, February 9, 2002
-
Tuned the SQL optimizer to favor more often index searches
over table scans.
-
Fixed a performance problem when several large SELECT
queries are run concurrently on a multiprocessor Linux computer.
Large CPU-bound SELECT queries will now also generally run faster on
all platforms.
-
If MySQL binlogging is used,
InnoDB now prints after crash recovery the latest MySQL binlog
file name and the position in that file (= byte offset)
InnoDB was able to recover to. This is useful, for example,
when resynchronizing a master and a slave database in replication.
-
Added better error messages to help in installation problems.
-
One can now recover also MySQL temporary tables which have become
orphaned inside the InnoDB tablespace.
-
InnoDB now prevents a FOREIGN KEY declaration where the signedness
is not the same in the referencing and referenced integer columns.
-
Fixed a bug: calling SHOW CREATE TABLE or SHOW TABLE STATUS
could cause memory corruption and make mysqld to crash.
Especially at risk was mysqldump, because it calls frequently
SHOW CREATE TABLE.
-
Fixed a bug: if on Unix you did an ALTER TABLE to an InnoDB table and
simultaneously did queries to it, mysqld could crash with an assertion
failure in row0row.c, line 474.
-
Fixed a bug: if inserts to several tables containing an auto-inc column
were wrapped inside one LOCK TABLES, InnoDB asserted in lock0lock.c.
-
In 3.23.47 we allowed several NULLS in a UNIQUE secondary index.
But CHECK TABLE was not relaxed: it reports the table as corrupt.
CHECK TABLE no longer complains in this situation.
-
Fixed a bug: on Sparc and other high-endian processors SHOW VARIABLES
showed innodb_flush_log_at_trx_commit and other boolean-valued
startup parameters always OFF even if they were switched on.
-
Fixed a bug: if you ran mysqld-max-nt as a service on Windows NT/2000,
the service shutdown did not always wait long enough for the InnoDB shutdown
to finish.
