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
.
