openSUSE 12.3 released with MariaDB as default

Congratulations to the openSUSE community on a successful release of openSUSE 12.3. A highlight worth mentioning is that MariaDB is now the default as opposed to MySQL. What are you waiting for, download it!

From the features list, here’s an excerpt focusing on MariaDB & MySQL:

openSUSE has moved from MySQL to MariaDB as default. MariaDB was first shipped with openSUSE 11.3 back in 2010. Over the years it proved itself and starting with 12.3 openSUSE is replacing default MySQL implementation with MariaDB. This means that whole distribution is compiled against MariaDB and in ‘M’ in LAMP means MariaDB from now. As MariaDB is a drop-in …

Using MariaDB on CentOS 6

This is just for testing purposes, but you might want to play around with MariaDB 5.5.29 coming via the CentOS 6 repositories as mentioned in this post. Please test it out and report bugs if required. The process was simple on a fresh install:

yum update
cd /etc/yum.repos.d/
wget http://dev.centos.org/centos/6/mariadb/mariadb.repo
yum list mariadb\*
yum install mariadb-server mariadb
/etc/init.d/mysqld start

That’s it, it just works. It comes with MEMORY, CSV, MRG_MYISAM, BLACKHOLE, MyISAM, PERFORMANCE_SCHEMA, ARCHIVE, FEDERATED, InnoDB (XtraDB) and Aria.

Remember this replaces mysql-libs, and is set to replace MySQL in your install. Here’s hoping it hits mainline CentOS soon.

See you at Northeast Gnu/Linuxfest & OpenDB Camp in Cambridge, MA

INNODB_SYS_FIELDS vs INNODB_SYS_COLUMNS

In MySQL 5.6 we have two new INFORMATION_SCHEMA tables for InnoDB that are likely going to cause confusion: INNODB_SYS_FIELDS and INNODB_SYS_COLUMNS. You may think these are likely to just be aliases of each other in order to make your life easier. However…

These are not the same thing. The INNODB_SYS_FIELDS table is all about key columns (fields) of InnoDB indexes, while INNODB_SYS_COLUMNS is about actual columns. This is even more confusing as within the MySQL source code, there is the Field set of objects that manipulate fields (columns) in a row.

Blegh. I’m glad it’s Friday.

WordPress and MySQL's strict mode

I really don’t like running my database in “I Love Garbage” mode, so I set the following SQL_MODE: STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO, NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO, NO_ENGINE_SUBSTITUTION,NO_ZERO_DATE, NO_ZERO_IN_DATE,ONLY_FULL_GROUP_BY Guess what WordPress does with that? It doesn’t install. If you set the SQL_MODE to empty and install WordPress, then restore the SQL_MODE, WordPress will run, but if you try to create a post you’ll see an error page that says “You are not allowed to edit this post.
