Dotdeb is a repository currently targeting Debian and Ubuntu, providing a nice set of packages for LAMP servers.

Recently, MySQL 5.6 was added to the dotdeb repository. On the surface, this is a very harmless addition. MariaDB is a replacement for MySQL and it should be possible for applications designed for MySQL to easily switch to MariaDB. Therefore MariaDB also includes the libraries that applications using MySQL depend upon, such as libmysqlclient18 and mysql-common. The dpkg package manager looks at the MySQL 5.6 packages in dotdeb and assumes that 5.6 is a higher version than 5.5, which results in it removing or replacing libraries during normal apt-get installation and upgrade procedures.

The problems appear in the following scenarios:

1. apt-get install mariadb-server-5.5 …

MariaDB 5.5.36 was recently released (it is the latest MariaDB 5.5), and is available for download here:

https://downloads.mariadb.org/mariadb/5.5.36/

This is a maintenance release, and so there are not too many big changes of note, just a number of normal bug fixes. However, there are a couple items worth mentioning:

1. Includes all bugfixes and updates from: MySQL 5.5.36
2. TokuDB is now included in RPM packages for CentOS 6 on x86-64

Note this release did not contain the bugfixes from XtraDB 5.5.36 yet. There is one bug fix in XtraDB 5.5.36 that is fairly serious, so if you are a *heavy* XtraDB+ user, I might wait for MariaDB 5.5.37 to be released, so you get this fix. I should note the bug was partially fixed in 5.5.35, and I did …

The MariaDB developers have made several releases in the past week. Rather than post about all of them separately, we decided to combine them into one post. Details for each release are available on their individual Release Notes and Changelog pages.

First up is MariaDB 5.5.36. This is a Stable (GA) release. Apart from general maintenance, bug fixes, and updates, TokuDB is now included in RPM packages for CentOS 6 on x86-64.

A few things to note recently, amongst MariaDB in distributions. 

1. Ubuntu keeps MySQL 5.5 despite MariaDB’s success. There’s a lot of reasons for this, but remember the key takeaway here is MySQL 5.5 & the fact that MariaDB wasn’t even in Debian yet when the decision was made.
2. MariaDB is now inside of Debian/sid – check out the packages.
3. RHEL 7 comes with MariaDB 5.5 as a default; this is a good thing.

Now, from a distribution standpoint, we’re looking at starting to ship 10.0 …

The MariaDB project is pleased to announce the immediate availability of MariaDB 5.5.34. This is a Stable (GA) release.

I’m always switching back-and-forth between the 2 different InnoDB flavors in MariaDB – XtraDB+ and the standard InnoDB plugin, so I thought I’d simply post all of the various combinations in a single place. (And then I cover enabling the InnoDB Plugin in MySQL, since it’s an option in 5.1.) [Addition: Thanks to Andrew and Sergei for the tips on shortening plugin-load=. The changes are reflected below.]

Note: Below is for Windows. For Linux, simply change “.dll” to “.so” where appropriate.

MariaDB 10.0:

Do not add anything, as the standard InnoDB plugin is the current default (as of 10.0.3, although I do anticipate this changing in the near future, and I’ll update the post accordingly when that happens).

MariaDB 5.5:

# Enable the 2 below to disable XtraDB+ and enable the standard InnoDB Plugin
ignore_builtin_innodb
plugin-load=ha_innodb.dll

…

We’re quite happy that we’ve released four major releases that are production ready (better known as generally available or GA in the MySQL world) in the last 26 months. That is just a little over two years, and a whole lot of features. In that same time, MySQL has seen one GA release (MySQL 5.5) and we’re all eagerly awaiting the upcoming MySQL 5.6.

You’ll note that we built MariaDB 5.1, 5.2, and 5.3 based on the MySQL 5.1 codebase. A significant number of features went into MariaDB 5.3 (our biggest GA release to date), with the biggest changes in the optimizer in over a decade. There were also many replication based …

As I mentioned here, there is a slight change for enabling the [original] InnoDB Plugin in MariaDB 5.5 (as compared to how you would enable it in 5.1).

Remember, in MariaDB 5.5, if you do not “enable” (i.e., add anything to the config file to do so) the InnoDB Plugin in MariaDB 5.5, you’ll end up with XtraDB+ for your InnoDb plugin. However, if you do “enable” the InnoDB plugin, then you end up with the original InnoDB plugin provided by Oracle/InnoDB.

The change is that the plugin file (.dll for Windows, .so file for Linux) which was previously named “ha_innodb_plugin.dll” is now just “ha_innodb.dll”.

Thus, if you previously enabled the plugin with (would have been in a 5.1 instance):

[mysqld]
ignore_builtin_innodb
plugin-load=innodb=ha_innodb_plugin.dll;innodb_trx=ha_innodb_plugin.dll; …
