Important Security Fixes

This release includes fixes for the following security vulnerabilities:

• A buffer overflow that can cause a server crash or arbitrary code execution (a variant of )

• / fast password brute-forcing using the "change user" command

• / information leakage about existing user accounts via the protocol handshake

• fixes for DoS attacks - crashes and server lockups (see the )

Additionally, it includes all security fixes from MySQL 5.5.29, such as fix for / and others such as:

Fedora 18 and Ubuntu 12.10 Packages

This version of MariaDB includes packages for Fedora 18 "Spherical Cow" and Ubuntu 12.10 "Quantal". Visit the to generate the necessary commands to install MariaDB on these distributions.

Discontinued builds

The MariaDB project tries to support as many different Operating Systems and Linux Distributions as we can. However, when a distribution or OS stops receiving security and other updates it becomes difficult to freely provide packages for that platform. In such cases, our policy is to deprecate that platform and stop providing binary packages for it.

As of 1 Feb 2013, we will stop building packages for the following:

• Fedora 16 "Verne"

• Debian 5 "Lenny"

• Ubuntu 10.10 "Maverick"

• Ubuntu 11.04 "Natty"

If your chosen Linux Distribution or Operating System is deprecated, packages or support are not completely unavailable. Companies such as and (and others) provide support for all versions of MariaDB back to even very old MySQL versions. This includes packaged binaries. Contact them for more details.

More information on our deprecation policy can be found at:

Archived Releases

From the beginning of the MariaDB project in 2009 we've kept all of our old releases online via our network of mirrors. Doing this is great for those few who are interested in old releases, but the disk space required to host all of our old releases is over 130 Gigabytes at present and grows by several gigabytes with each new release. This is too much for some of our mirrors to handle. So, starting with this release our primary mirror will only host the most recent three or four releases in each series (5.5, 10.0, and so on). Mirrors are, of course, free to keep archiving every release, but the primary mirror that they pull from will not.

Old releases do have value, so for those that are interested in old releases, we are setting up a simple, no frills, archive server which will host them. Once the server is up and running, links to archived releases on will point at the archive server. During the transition period, links to some old releases may disappear for a short time, but don't worry, they haven't been deleted, they're just being moved!

Thanks, and enjoy MariaDB!

Alternative Linux binaries

In this version of MariaDB we are starting to provide alternative Linux binaries built on a different build machine with a different build toolchain. Binaries created on this box require at least GLIBC_2.14. For continuity, we are still providing binaries built with the same toolchain as previous releases. The alternative binaries have a "(GLIBC_2.14)" label to distinguish them from the others.

Fixes and Performance Enhancements

This release includes fixes for the following security vulnerabilities:

This release fixes numerous cases of the incorrect identifier quoting in the replication code. They were open vulnerabilities, that allowed, to a certain extent, to bypass the database privilege system and modify the data, that one was granted no access to. See for details. ()

Additionally, 5.5.27 includes several other bug fixes and performance enhancements.

Security fix

• A fix is included for a COM_BINLOG_DUMP crash on invalid data. See for details.

Threadpool

is the first release to feature the new . This is comparable in functionality to the closed-source feature in MySQL Enterprise.

Preliminary benchmarks of the new threadpool code are available .

For our Windows users, pool-of-threads is now the default scheduler on Windows Vista (and higher). It is not the default on Linux/Unix yet as we don't feel we have had enough time to thoroughly test various corner cases.

Updated SphinxSE

has been updated to version 2.0.4 (the latest upstream version) in .

LIMIT ROWS EXAMINED

In 5.5.21 there is a new LIMIT ROWS EXAMINED optimization which provides the means to terminate the execution of statements which examine too many rows, and thus use too many resources. This is achieved through an extension of the clause —LIMIT ROWS EXAMINED <number_of_rows>. Whenever possible the semantics of LIMIT ROWS EXAMINED is the same as that of normal LIMIT (for instance for aggregate functions).

More information is available on the page.

INSTALL SONAME

includes a new INSTALL SONAME statement. This statement is a variant of . It installs all plugins from a given plugin_library.

See the page for details.

Extended Keys support for XtraDB and InnoDB

In 5.5.21 there is a new "extended keys" optimization which, when enabled, makes use of existing components of InnoDB/XtraDB keys to generate more efficient execution plans. Using these components in many cases allows the server to generate execution plans which employ index-only look-ups.

See the page for more information.

Non-blocking Client Library

MariaDB, starting with version 5.5.21 supports . This allows an application to start a query or other operation against the database, and then continue to do other work (in the same thread) while the request is sent over the network, the query is processed in the server, and the result travels back. As parts of the result become ready, the application can — at its leisure — call back into the library to continue processing, repeating this until the operation is completed.

Non-blocking operation is implemented entirely within the client library. This means no special server support is necessary and non-blocking operation works with any version of the MariaDB or MySQL server, the same as the normal blocking API. It also means that it is not possible to have two queries running at the same time on the same connection (this is a protocol limitation). But a single thread can have any number of non-blocking queries running at the same time, each using its own MYSQL connection object.

See for details.

mysql_real_connect() Changes

In MySQL, and in MariaDB versions before 5.5.21, mysql_real_connect() removes from the MYSQL object any options set with mysql_option() when it fails. Beginning with , options are preserved by a failingmysql_real_connect(); use mysql_close(), as normal, to clear them.

This only has effect if the MYSQL object is reused after amysql_real_connect() failure (which is unusual). No real-life incompatibilities are expected from this change (it is unlikely that an application would rely on options being automatically removed between connection attempts).

Selectively skipping replication of binlog events

Normally, all changes that are logged as events in the binlog are also replicated to all slaves (though still subject to filtering by--replicate-do-xxx, --replicate-ignore-xxx, and similar options). However, sometimes it may be desirable to have certain events be logged into the binlog, but not be replicated to all or a subset of slaves, where the distinction between events that should be replicated or not is under the control of the application making the changes.

This could be useful if an application does some replication external to the server outside of the built-in replication, or if it has some data that should not be replicated for whatever reason.

This is possible with two new system variables introduced in : @@skip_replication and --replicate-events-marked-for-skip.

See for details.

MariaDB 5.5 is no longer maintained. Please use a more recent release.

The most recent release in the MariaDB 5.5 series is:MariaDB 5.5.68 Download Now

MariaDB 5.5 is MariaDB 5.3 + MySQL 5.5, with added features. The first stable release was in April 2012, and the final release in May 2020.

For upgrading to MariaDB 10.0, the more recent stable release, see .

Feature Comparison Matrix

We have created an Optimizer Feature Comparison Matrix showing the new optimizer features in and 5.3 compared to MySQL 5.5 and 5.6.

New Features

• Significantly more efficient , comparable in functionality to the closed source feature in MySQL Enterprise.

• ()

• ()

• updated to version 2.0.4.

Information Schema

There are a number of new tables:

Minor Extensions

• Updates to performance schema tables are not stored in the and thus not replicated to slaves. This is to ensure that monitoring of the master will not cause a slower performance on all slaves. This also fixes a crash on the slaves.

New features are added to .

Deprecated / Disabled Features

• is no longer in the binary builds/distributions. It's however still in the source distributions and in the source tree. The reason is that PBXT is no longer actively maintained, has a few bugs that are not fixed and is not in widespread use.

Switching Between InnoDB and
