MySQL Reference Manual for version 4.0.18.
C.4.12 Changes in release 3.23.48 (07 Feb 2002)
-
Added
--xml option to mysqldump for producing XML output.
-
Changed to use
autoconf 2.52 (from autoconf 2.13)
-
Fixed bug in complicated join with
const tables.
-
Added internal safety checks for
InnoDB.
-
Some
InnoDB variables were always shown in SHOW VARIABLES as
OFF on high-byte-first systems (like SPARC).
-
Fixed problem with one thread using an
InnoDB table and another
thread doing an ALTER TABLE on the same table. Before that,
mysqld could crash with an assertion failure in `row0row.c',
line 474.
-
Tuned the
InnoDB SQL optimizer to favor index searches more often
over table scans.
-
Fixed a performance problem with
InnoDB tables 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 name and the 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 of
InnoDB
tables.
-
It is now possible to recover MySQL temporary tables that 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.
-
Calling
SHOW CREATE TABLE or SHOW TABLE STATUS could cause
memory corruption and make mysqld crash. Especially at risk was
mysqldump, because it frequently calls SHOW CREATE TABLE.
-
If inserts to several tables containing an
AUTO_INCREMENT column were
wrapped inside one LOCK TABLES, InnoDB asserted in
`lock0lock.c'.
-
In 3.23.47 we allowed several
NULL values in a UNIQUE secondary
index for an InnoDB table. But CHECK TABLE was not relaxed: it
reports the table as corrupt. CHECK TABLE no longer complains in
this situation.
-
SHOW GRANTS now shows REFERENCES instead of REFERENCE.
