MySQL 5.1.7-beta has been released

Hi,


MySQL 5.1.7-beta, a new version of the popular Open Source Database
Management System, has been released. The Community Edition is now
available in source and binary form for a number of platforms from our
download pages at
http://dev.mysql.com/downloads/ and mirror sites.


Note that not all mirror sites may be up to date at this point in time -
if you can't find this version on some mirror, please try again later or
choose another download site.


This is the first published Beta release in the 5.1 series.
All attention will continue to be focused on fixing bugs and stabilizing
5.1 for later production release.


NOTE: This Beta release, as any other pre-production release, should not
be installed on ``production'' level systems or systems with critical
data. It is good practice to back up your data before installing any new
version of software. Although MySQL has worked very hard to ensure a
high level of quality, protect your data by making a backup as you would
for any software beta release.


Please refer to our bug database at http://bugs.mysql.com/ for more
details about the individual bugs fixed in this version.


We welcome and appreciate your feedback!


News from the ChangeLog:

Functionality added or changed:
* Incompatible change: TYPE = engine_name is no longer accepted as a
synonym for the ENGINE = engine_name table option. (TYPE has been
deprecated for some time already.)
* Added the mysql_upgrade program that checks all tables for
incompatibilities with the current version of MySQL Server and
repairs them if necessary. This program should be run for each MySQL
upgrade (rather than mysql_fix_privilege_tables). See Section 5.5.2,
"mysql_upgrade --- Check Tables for MySQL Upgrade."
* All subpartitions within a given partitioned table are now
guaranteed to have unique names.
(Bug #15408 (http://bugs.mysql.com/15408))
* Added the FOR UPGRADE option for the CHECK TABLE statement. This
option checks whether tables are incompatible with the current
version of MySQL Server. Also added the --check-upgrade option to
mysqlcheck that invokes CHECK TABLE with the FOR UPGRADE option.
Added the --fix-db-names and --fix-table-names options to
mysqlcheck.
* Added the RENAME DATABASE statement.
This is a first version with limited functionality, especially it
does not migrate any stored routines or events to the new schema
(stored routines and events must be redefined in the new database).
Its current main purpose is for migration of old data that uses
filenames/dirnames in some coding page to the new filename encoding.
Like a RENAME TABLE, it will also not change any account privileges
listed in the system tables (this needs to be done manually, if this
is required for the renamed table).
* The SQL mode in effect at the time an event is created or altered is
recorded and used during event execution.
(Bug #16407 (http://bugs.mysql.com/16407))
* Added the PROCESSLIST table to INFORMATION_SCHEMA.
* Attempting to read pre-5.1.6 partitioned tables with a MySQL 5.1.7
(or later) server now generates a suitable warning message.
(Bug #16695 (http://bugs.mysql.com/16695))
For additional information about this issue, see Section D.1.3,
"Changes in release 5.1.6 (01 February 2006)."
* NDB Cluster: Attempting to SELECT ... FROM INFORMATION_SCHEMA.FILES
now raises a warning in the event that the cluster has crashed.
(Bug #17087 (http://bugs.mysql.com/17087))
* Removed the have_isam and have_raid system variables.
* Status messages added to ndb_restore to allow users to know that
data files for Disk Data are being created.
(Bug #16873 (http://bugs.mysql.com/16873))
* Added the IN NATURAL LANGUAGE MODE and IN NATURAL LANGUAGE MODE WITH
QUERY EXPANSION modifiers for full-text searches. See Section 12.7,
"Full-Text Search Functions."
* Creator privileges are now checked for all events before execution.
(Bug #17289 (http://bugs.mysql.com/17289))
* CREATE/DROP/ALTER EVENT statements are not allowed in triggers.
(Bug #16410 (http://bugs.mysql.com/16410))

Bugs fixed:
* The mysql_fix_privilege_tables.sql script did not properly
initialize the Event_priv column to 'Y' for those accounts that
should have the EVENT privilege.
(Bug #16400 (http://bugs.mysql.com/16400))
* NDB Cluster: Inserting the output of REPEAT('some_string', some_int)
into a BLOB column resulted in the error Invalid blob attributes or
invalid blob parts table. (Bug #17505 (http://bugs.mysql.com/17505))
* NDB Cluster: Row-based replication was not being set up correctly if
a backup was already in progress. For example, connecting a mysqld
instance to a cluster which was being backed up would result in the
message NDB: skipping setup table test.t1 being written to the error
log. (Bug #17459 (http://bugs.mysql.com/17459))
* NDB Cluster: CREATE TEMPORARY TABLE of a Cluster table would fail
with an Unsupported error or crash the server.
(Bug #17210 (http://bugs.mysql.com/17210),
Bug #16552 (http://bugs.mysql.com/16552))
* NDB Cluster: UNIQUE keys in Cluster tables were limited to 225 bytes
in length. (Bug #15918 (http://bugs.mysql.com/15918))
* NDB Cluster: REPLACE failed when attempting to update a primary key
value in a Cluster table. (Bug #14007 (http://bugs.mysql.com/14007))
* NDB Cluster: Creating NDB tables containing BLOB columns but no
primary key caused unpredictable behavior.
(Bug #17559 (http://bugs.mysql.com/17559))
* Creating an event and using a whitespace character other than space
following the DO keyword caused a server crash.
(Bug #17453 (http://bugs.mysql.com/17453))
* Previously, a stored function invocation was written to the binary
log as DO func_name() if the invocation changes data and occurs
within a non-logged statement, or if the function invokes a stored
procedure that produces an error. These invocations now are logged
as SELECT func_name() instead for better control over error code
checking (slave servers could stop due to detecting a different
error than occurred on the master).
(Bug #14769 (http://bugs.mysql.com/14769))
* CHECKSUM TABLE returned different values on MyISAM table depending
on whether the QUICK or EXTENDED options were used.
(Bug #8841 (http://bugs.mysql.com/8841))
* Querying the INFORMATION_SCHEMA.partitions table on a non-max server
caused a server crash. (Bug #16591 (http://bugs.mysql.com/16591))
* MySQL server dropped client connection for certain SELECT statements
against views defined that used MERGE algorithm.
(Bug #16260 (http://bugs.mysql.com/16260))
* A statement containing GROUP BY and HAVING clauses could return
incorrect results when the HAVING clause contained logic that
returned FALSE for every row.
(Bug #14927 (http://bugs.mysql.com/14927))
* Using GROUP BY on column used in WHERE clause could cause empty set
to be returned. (Bug #16203 (http://bugs.mysql.com/16203))
* DROP DATABASE did not drop events for the database.
(Bug #16406 (http://bugs.mysql.com/16406))
* Race conditions between event creation, dropping, and execution
could result in a server crash or hang.
(Bug #17373 (http://bugs.mysql.com/17373))
* SET sql_mode = N, where N > 31, did not work properly.
(Bug #13897 (http://bugs.mysql.com/13897))
* Repeated invocation of my_init() and my_end() caused corruption of
character set data and connection failure.
(Bug #6536 (http://bugs.mysql.com/6536))
* When used with the ExtractValue() function, an XPath expression
having no leading "/" character would crash the server.
(Bug #16234 (http://bugs.mysql.com/16234))
* Attempting to add a new partition to a table partitioned by a unique
key would cause an Out of memory error.
(Bug #17169 (http://bugs.mysql.com/17169))
* A SELECT from the last partition of a subpartitioned table having a
UNIQUE KEY could crash the MySQL Server.
(Bug #16907 (http://bugs.mysql.com/16907))
* A SELECT on a subpartitioned table having a multiple-column PRIMARY
or UNIQUE KEY, and whose partitioning function used only the first
column of the key, could cause mysqld to crash.
(Bug #16901 (http://bugs.mysql.com/16901))
* Using REPLACE INTO on a partitioned table having a primary key would
crash the server in the event of a duplicate key error.
(Bug #16782 (http://bugs.mysql.com/16782))
* DROP TABLE would sometimes fail on a table having subpartitions that
used the default storage engine.
(Bug #16775 (http://bugs.mysql.com/16775))

between multiple SQL nodes was not handled correctly when binary
logging was enabled (a timeout error resulted).
(Bug #17415 (http://bugs.mysql.com/17415))
* NDB Cluster: Table definitions were not shared between multiple SQL
nodes in a cluster without binary logging being enabled.
(Bug #17414 (http://bugs.mysql.com/17414))
* NDB Cluster: Cluster log file paths were truncated to 128
characters. They may now be as long as MAX_PATH (the maximum path
length permitted by the operating system).
(Bug #17411 (http://bugs.mysql.com/17411))
* SHOW CREATE EVENT displayed no output.
(Bug #16423 (http://bugs.mysql.com/16423))
* Statements that contained Unicode characters were not logged to the
log tables correctly. (Bug #16905 (http://bugs.mysql.com/16905))

(Bug #17188 (http://bugs.mysql.com/17188))
* Trying to create a partitioned table with more than 32 attributes
failed. (Bug #17179 (http://bugs.mysql.com/17179))
* NDB Cluster: When attempting to import data into an NDB table using
LOAD DATA INFILE, the server would hang in the event of a duplicate
key error. (Bug #17154 (http://bugs.mysql.com/17154))

into NDB tables. (Bug #17081 (http://bugs.mysql.com/17081))
* NDB Cluster: Performing large numbers of data manipulation
statements on cluster tables using Disk Data could lead to a server
crash. ()
