MySQL Database Server 5.1.59 has been released
Dear MySQL users,
MySQL Server 5.1.59, a new version of the popular Open Source
Database Management System, has been released. MySQL 5.1.59 is
recommended for use on production systems.
For an overview of what's new in MySQL 5.1, please see
http://dev.mysql.com/doc/refman/5.1/en/mysql-nutshell.html
For information on installing MySQL 5.1.59 on new servers or upgrading
to MySQL 5.1.59 from previous MySQL releases, please see
http://dev.mysql.com/doc/refman/5.1/en/installing.html
MySQL Server is available in source and binary form for a number of
platforms from our download pages at
http://dev.mysql.com/downloads/
Not all mirror sites may be up to date at this point in time, so if you
can't find this version on some mirror, please try again later or choose
another download site.
We welcome and appreciate your feedback, bug reports, bug fixes,
patches, etc:
http://forge.mysql.com/wiki/Contributing
For information on open issues in MySQL 5.1, please see the errata
list at
http://dev.mysql.com/doc/refman/5.1/en/open-bugs.html
The following section lists the changes in the MySQL source code since
the previous released version of MySQL 5.1. It may also be viewed
online at
http://dev.mysql.com/doc/refman/5.1/en/news-5-1-59.html
Enjoy!
===
D.1.2. Changes in MySQL 5.1.59 (15 September, 2011)
Functionality Added or Changed
* If the --with-ndbcluster option is given to the configure
script, it now produces a warning that the version of MySQL
Cluster included in 5.1 is no longer maintained. (The separate
MySQL Cluster distribution should be used instead.) (Bug
#49093, Bug #11757091)
Bugs Fixed
* InnoDB Storage Engine: The random read-ahead
(http://dev.mysql.com/doc/innodb-plugin/1.0/en/glossary.html#g
los_read_ahead) feature that was removed from the InnoDB
Plugin is now available again. Because it is only helpful for
certain workloads, it is turned off by default. To turn it on,
enable the innodb_random_read_ahead configuration option.
Because this feature can improve performance in some cases and
reduce performance in others, before relying on this setting,
benchmark both with and without the setting enabled. (Bug
#12356373)
* Partitioning: Auto-increment columns of partitioned tables
were checked even when they were not being written to. In
debug builds, this could lead to a server crash. (Bug
#11765667, Bug #58655)
* The option-parsing code for empty strings leaked memory. (Bug
#12589928)
* Replication: Processing of corrupted table map events could
cause the server to crash. This was especially likely if the
events mapped different tables to the same identifier, such as
could happen due to Bug#56226.
Now, before applying a table map event, the server checks
whether the table has already been mapped with different
settings, and if so, an error is raised and the slave SQL
thread stops. If it has been mapped with the same settings, or
if the table is set to be ignored by filtering rules, there is
no change in behavior: the event is skipped and IDs are not
checked. (Bug #44360, Bug #11753004)
See also Bug #11763509.
* ALTER TABLE {MODIFY|CHANGE} ... FIRST did nothing except
rename columns if the old and new versions of the table had
exactly the same structure with respect to column data types.
As a result, the mapping of column name to column data was
incorrect. The same thing happened for ALTER TABLE DROP COLUMN
... ADD COLUMN statements intended to produce a new version of
the table with exactly the same structure as the old version.
(Bug #61493, Bug #12652385)
* For a lower_case_table_names value of 1 or 2 and a database
having a mixed-case name, calling a stored function using a
fully qualified name including the database name failed. (Bug
#60347, Bug #11840395)
* Previously, Performance Schema table columns that held byte
counts were BIGINT UNSIGNED. These were changed to BIGINT
(signed). This makes it easier to perform calculations that
compute differences between columns. (Bug #59631, Bug
#11766504)
* For MyISAM tables, attempts to insert incorrect data into an
indexed GEOMETRY column could result in table corruption. (Bug
#57323, Bug #11764487)
* A race condition between loading a stored routine using the
name qualified by the database name and dropping that database
resulted in a spurious error message: The table mysql.proc is
missing, corrupt, or contains bad data (Bug #47870, Bug
#11756013)
* Upgrades using an RPM package recreated the test database,
which is undesirable when the DBA had removed it. (Bug #45415,

(Bug #11766513, Bug #59641) * Partitioning: When executing a row-ordered retrieval index merge, the partitioning handler used memory from that allocated for the table, rather than allocated to the query, causing table object memory not to be freed until the table was closed. (Bug #11766249, Bug #59316) * Replication: When mysqlbinlog was invoked using --base64-output=decode-row and --start-position=pos, (where pos is a point in the binary log past the format description log event), a spurious error of the type shown here was generated: malformed binlog: it does not contain any Format_description_log_event... However, since there is nothing unsafe about not printing the format description log event, the error has been removed for this case.

(Bug #59270, Bug #11766212) * In ROUND() calculations, a Valgrind warning for uninitialized memory was corrected. (Bug #58937, Bug #11765923) * Valgrind warnings caused by comparing index values to an uninitialized field were corrected. (Bug #58705, Bug #11765713) * LOAD DATA INFILE errors could leak I/O cache memory.

It may also be viewed online at http://dev.mysql.com/doc/refman/5.1/en/news-5-1-56.html Changes in MySQL 5.1.56 (01 March 2011): Functionality added or changed: * mysqldump --xml now displays comments from column definitions. (Bug #13618) Bugs fixed: * InnoDB Storage Engine: InnoDB returned values for rows examined in the query plan that were higher than expected. NULL values were treated in an inconsistent way. The inaccurate statistics could trigger false positives in combination with the MAX_JOIN_SIZE setting, because the queries did not really examine as many rows as reported. (Bug #30423) * Partitioning: Trying to use the same column more than once in the partitioning key when partitioning a table by KEY caused mysqld to crash. Such duplication of key columns is now expressly disallowed, and fails with an appropriate error. (Bug #53354, Bug #57924) * Replication: When using the statement-based logging format, INSERT ON DUPLICATE KEY UPDATE and INSERT IGNORE statements affecting transactional tables that did not fail were not written to the binary log if they did not insert any rows. (With statement-based logging, all successful statements should be logged, whether they do or do not cause any rows to be changed.) (Bug #59338) * Replication: Formerly, STOP SLAVE stopped the slave I/O thread first and then stopped the slave SQL thread; thus, it was possible for the I/O thread to stop after replicating only part of a transaction which the SQL thread was executing, in wich case---if the transaction could not be rolled back safely---the SQL thread could hang. Now, STOP SLAVE stops the slave SQL thread first and then stops the I/O thread; this guarantees that the I/O thread can fetch any remaining events in the transaction that the SQL thread is executing, so that the SQL thread can finish the transaction if it cannot be rolled back safely. (Bug #58546) * A query of the following form returned an incorrect result, where the values for col_name in the result set were entirely replaced with NULL values: SELECT DISTINCT col_name ... ORDER BY col_name DESC; (Bug #59308, Bug #11766241) * DELETE or UPDATE statements could fail if they used DATE or DATETIME values with a year, month, or day part of zero. (Bug #59173) * The ESCAPE clause for the LIKE operator allows only expressions that evaluate to a constant at execution time, but aggregrate functions were not being rejected. (Bug #59149) * Memory leaks detected by Valgrind, some of which could cause incorrect query results, were corrected. (Bug #59110, Bug #11766075) * mysqlslap failed to check for a NULL return from mysql_store_result() and crashed trying to process the result set. (Bug #59109) * In debug builds, SUBSTRING_INDEX(FORMAT(...), FORMAT(...)) could cause a server crash. (Bug #58371) * When mysqldadmin was run with the --sleep and --count options, it went into an infinite loop executing the specified command. (Bug #58221) * Some string manipulating SQL functions use a shared string object intended to contain an immutable empty string. This object was used by the SQL function SUBSTRING_INDEX() to return an empty string when one argument was of the wrong datatype. If the string object was then modified by the SQL function INSERT(), undefined behavior ensued. (Bug #58165, Bug #11765225) * Parsing nested regular expressions could lead to recursion resulting in a stack overflow
Upgrading of mysql database
Hi All Sorry for all my posts today but this one client is keeping me busy. the version of MySQL installed on the ubuntu server is 5.0.51a-3ubuntu5.8-log as this was the latest one available in the repository. We will need to upgrade this to version 5.1.53. Am I correct in assuming the following steps? 1. setup version 5.1.53 on the machine (different port) 2. shutdown the current database. 3. create backup file 4. restore backup 5. change port to 3306 6. startup new database. 7. disable the old database so that it would not start up during reboot. Regards Machiel
Re: Upgrading of mysql database
That would work, yes. You could also try to upgrade in place - the upgrade scripts *should* take care of everything between those versions, I think.

Replace the software - if you're using packaged versions, they should take care of most anything. If not, there's mysql-upgrade or some script. See the online docs for specifics.

Recover accidentally deleted MySQL database files

Re: Recover accidentally deleted MySQL database files
And this is why you have backups :-) You have little guarantee that the recovered blocks form complete files, but you can try to move them into the directory (with the correct mdi, myd and frm extensions and named consistently, of course) and try to figure out what contains which data from the contents of the tables. The first challenge, however, is going to be matching the correct .frm file to the correct .myd and .mdi. I guess you could skip the .mdi files, as they're just indices, that'll make the job slightly easier at least. Keep the originally recovered files, too, just in case MySQL tries to write to some of them and corrupts them. I hope you enjoy puzzles...

Re: question regarding mysql database location
You don't need to move any databases. Look at this structure: /data/disk1/mysql/db1 (directory) /db2 (directory) /db3 (directory) /db4 (symlink to /data/disk2/mysql/db4) /db5 (symlink to /data/disk2/mysql/db5) /db6 (symlink to /data/disk2/mysql/db6) /disk2/mysql/db4 (directory) /db5 (directory) /db6 (directory) If your mysql data directory is set to /data/disk1/mysql, the server will pick up the symlinks there and use them as if they were just ordinary directories.

Porting MySQL database across international sites
Hello everybody, the MySQL application I'm building needs to be ported from my current site to the hosting site - which is based on another nation. The problem I'm having is that the login doesn't work as the password doesn't match in the charset of the new hosting site. To address this problem, I have made some changes to the server configuration: - set default charset as utf8 (originally it was latin1) Plus, I've made some correction to the J2EE application: - forcing the JVM to start with the option -Dfile.encoding=UTF-8 But still, the passwords doesn't match when trying to log in. Any suggestion or hint about what I should look into? To me, it appears that all the settings have been properly changes, but there is something missing. Thanks! Dan

Re: MySQL database synchronization
Hi, If you have 256Kbps should not be a problem as long as it used most for mysql, if there are too may other user accessing net then it would be too slow. When you say, you want to access from both the sites, does it mean there would be read and write from both sites or just read from from one site and write from other sites. If its just read from one site and read and write from other site then, you can setup a master where read and write happen and slave where only read happens. Also, the slave can be used as a backup. There are many third party software available where you can manually apply bin-logs from one site to other, but this is little complicated and need precise scripting taking care of all the bin-log position. regards anandkl On Jan 25, 2008 4:17 AM, C K [EMAIL PROTECTED] wrote: I have a problem related with 2 mysql database synchronization.

Re: preferred way to backup a 20GB MySQL database
What about the MySQL Administration backup routine, which can be scheduled for a convenient time? No-one has mentioned this one. We use it but perhaps there is something I should know...? Thanks Jonathan Trahair - Original Message - From: B. Keith Murphy To: Dan Buettner Cc: David Campbell ; MySql Sent: Wednesday, November 28, 2007 2:55 AM Subject: Re: preferred way to backup a 20GB MySQL database I would echo what Dan says. In addition, from the slave server, you might look at running the new mysql-parallel-dump tool that Baron Schwartz has developed. It essentially does a dump with a thread running (by default) for each CPU core you have. A dual core box will run two threads and dump roughly twice as fast as a normal mysqldump. In addition, it compresses the output making it much more compact. He has renamed the toolkit to Maatkit and it is available at http://maatkit.sourceforge.net/. Also, you might look into using an LVM snapshot to run the copy from. That way it doesn't interfere with your operations as much. I do that for some of our production slave servers myself. Keith Dan Buettner wrote: I'd strongly recommend setting up replication, and then taking your backups from the replica. mysqlhotcopy works great, I used it for years myself, but it does require freezing your database while the copy happens.

how to restore mysql database after Crash
Hey, Environment: Windows 2003 server Mysql 5.0 server Problem: Our server crashed and the c drive was formatted. Unfortunately we did not have a backup of the mysql databases which we were using.

Recover your files first and then you can see where you can go. I suppose you now have backup plans in place now?

MySQL Database Administrator/ Data Architect - LONDON
hi everyone, i am looking to find a MySQL guru to come work full time at a passionate mobile technology/ communications company in the heart of London. This truly is the place to be!

We need to find a DBA to take control of the MySQL RDBMS and the data held therein. The role will actually combine elements of Data Architect too. The role is going to involve liaising with the application developers and the network operations team. The dress style of the company is informal and they also have a Nintendo Wii in the office that anybody can play on at any time of the day(work load permitting of course).

A... the one thing I can't do... I don't have Access to well...

Not the rest of the 934 records... You are using ENCLOSED BY '' in your SQL, which I have had cause hassle with excel generated csv files. Basically, excel will only wrap field values in double quotes if the value contains the field delimiter. This caught me out, although I seem to remember I did get an error. Try removing the ENCLOSED BY anyway, it's optional. Another thing to watch for is column headers in your input file that may be triggering column constraints. You can get past this by using the IGNORE n LINES syntax in your command. I usually specify the table column names too - I have happily loaded up csv files from excel with something like the following: LOAD DATA LOCAL INFILE 'file.csv' INTO TABLE MyTable FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' IGNORE 1 LINES (column1,column2,column_etc); Hope this helps.

Re: Import file into MySQL Database..
I believe that excel files generally terminate lines with '\r\n' and if you use terminated by '\n' it will cause this behavior. so try it with lines terminated by '\r\n' or get TextPad or a similar editor that can save the file as unix platform that uses the same line terminators that MySQL expects by default and leave out the optional terminated by cj On 8/8/07, Jason Pruim [EMAIL PROTECTED] wrote: Okay, so I have been going crazy trying to figure this out...

Re: MySQL database synchronizing from 2 locations
Hello, As per your suggestions I tried to get some correct solution for the problem, but there is a big problem for replication and it is network connection. Though Internet is available to the Mfg. Site, it is not having good speed and continuous. So that replication may not be a good choice. As we are using Auto-increment fields for each table and it is Primary Key and also physical records are already marked with this PK. Is there any other solution for this? Please give the details. Thanks CPK -- Keep your Environment clean and green.
Re: MySQL database synchronizing from 2 locations
Sorry maybe this is completly out of topic, but why do you need it to synchronise in two locations, can't you just get both servers to connect to the same database? And then if you need you can set a cron to backup your database hourly or daily to the other server using mysql dump and scp. I don't understand the need to always have the same in two locations as this uses up twice the amount of ressources.

MySQL database synchronizing from 2 locations
Hello, My client has a mfg. unit at 65 Km from a city in India. He wants to connect to his corporate office in the city. Both offices will use same data and same ERP system. He is using Win 2K3 server and MySQL 5.0.17. Is it possible to make them synchronized at a particular or regular intervals? How? Please give details. Options I think - Replication (is it possible for Windows?) Cluster (Is it possible?) Manual Sync by using Navicat or any other tool (other tools please) Please help. Prior Thanks, CPK -- Keep your Environment clean and green.
RE: MySQL database synchronizing from 2 locations
Replication works with Windows (we do it extensively here at work). And it's definitely one option. But if there are any problems, then without some monitoring mechanism, you'll not be alerted if replication chokes (all that will happen is that updates to the slave will seemingly just stop). You can implement any of a bunch of alerting and self-repair mechanisms. Other methods of transferring the data are similarly challenging. You can do an automated MySQLDUMP on a periodic basis with with a --master-data option (in case you do perform the replication) just to be sure OR just do MySQLDumps each night (depending on the volume). It all depends on the degree and need for whatever level of synchronicity.

RE: MySQL database synchronizing from 2 locations
Hi, Set up two-way replication between Corporate and Manufacturing. As long as a live network connection is available between the two sites, replication will carry on. Make sure that all your hardware is able to handle the peak I/O loads, in order to keep replication humming along seamlessly. If the connectivity between the two servers is lost, replication will gracefully auto-recover. You will need to set up some heartbeat script to monitor the connectivity, and SMS/email you if it is lost, allowing you to check on it.

multilanguage web application with mysql database?
I have many tables like the table Person:below, in mysql database. person_id, first_name,last_name, mi, gb_first_name, gb_last_name, b5_first_name, b5_last_name, gender, dob where different columns storing strings in different encodings. At anytime, a web user can switch the language and the application will get the values in the right columns to generate web pages. The purpose of Multi-language tables is to make multilanguage dynamic content management easier for web applications. For example, to add a person record, the user enter the English name, then switch the session language to gb2312, enter the Chinese name in gb2312, and then switch the session language to big5, enter the name in big5. And then commit the data into the database. The whole thing sounds complicated but can be treated as a pattern and let a framework to take care of those and the code can be as clean as a single language app. I actually have the framework that works well for me with mysql database. I didn't do anything about language encoding in mysql database, it just worked for me. At least with english, gb2312 and big5 altogether in a table like table Person above. I noticed that (english, gb2312, big5, Jp) cannot work together (where jp is any kind of japaness language encoding). My approach seems fine with most western languages So after all such experimental work, I still don't know how to make a real multi language web app such that the languages are switchable within the same session. Any suggestions? Any web application known to be able to solve the problem? Thanks

Forget about big5, gb2312, shift_jis etc! Also, web forms submit content in the encoding of the web page. So make sure your http content-type header is set to UTF-8 for all web pages. I'm not sure what technology you're using - php/java etc? By default, most web servers/applications serve content as ISO-8859-1encoding - which only works for western European languages. - unless you specifically tell it otherwise. In a JSP for example, you need to put this directive at the top of a page: %@ page contentType=text/html;charset=UTF-8 pageEncoding=UTF-8 % This article is useful - http://java.sun.com/developer/technicalArticles/Intl/HTTPCharset/index.html even if you're not using Java technology. ~mm
Speed of queries in a MySQL database
Hi Everyone. I have just upgraded a Visual Basic 6 project which used an Access database as a data back end, using DAO and SQL strings. The Access database was exceedingly slow, and prone to glitches. I have changed the VB code to ADO, and set up a MySQL database in the hope that the MySQL database would be better suited to the large size of some tables, and would therefore return queries more quickly. It is now populated with the data from the old Access tables. So far, the MySQL speed has been very slow. I'm talking about 30 seconds to return the 2 records found by SELECT * FROM OrderItems WHERE CustomerCode = 'ABE001' AND InvoiceNo = 0 ORDER BY OrderNumber, ProductCode, Colour, RecNo from the OrderItems table - 309,000 rows (ie. records). And this is in the MySQL Query Browser, not the VB code. Database information: all 23 tables use the InnoDB, 2 tables have more than 276,000 records, most have a lot less. Uses ODBC. My questions are: 1. Have I chosen the right database? What databases do people use which return data from huge tables in micro-seconds (well, alright, seconds, then!)? 2. Should I set up the database in a different way, if so, how? 3. Is this the right list for such questions? Thanks in advance. Jonathan Trahair

Jonathan Trahair Jonathan, If you are going to use CustomerCode and InvoiceNo to retrieve the rows, then create a compound index with CustomerCode and InvoiceNo in that one index. Why did you choose InnoDb instead of MyISAM? Do you need RI or are there a lot of people updating the table at the same time? If not, MyISAM might be a better choice because it's faster.

RE: Mmultiple languages in the MySQL database
That's a good suggestion. As it happens, I have a web-based application that should display the data, but it doesn't. Without going into detail, all of the Chinese data is in one account and nothing shows in that account in the web application even though I can see the records with the MySQL client. Now I'm chasing that hare.

Re: Access mySQL database across Internet
You could look into establishing persistent connections. Know it's possible with mod_perl and I believe PHP. Not sure about ASP. Basically, this leaves a connection always open, eliminating the overhead of resolving host, connecting, authenticating, switching to the proper database. Not really a lot of time saved but for a high-volume site it can make a difference; also may help if you are experiencing network latency. Is establishing a connection what you feel is slow? Or the transfer of data between your servers is what's slow? Dan On 8/15/06, Neil Tompkins [EMAIL PROTECTED] wrote: The connection time to my mySQL database is OK from the ASP page.
