MariaDB 5.5.44 Overview and Highlights

MariaDB 5.5.44 was recently released (it is the latest MariaDB 5.5), and is available for download here:

https://downloads.mariadb.org/mariadb/5.5.44/

This is a maintenance release, and no major changes, so there are only several noteworthy items (but one of those being a security fix and five potential crashing bug):

  • Security Fix: Client command line option –ssl-verify-server-cert (and MYSQL_OPT_SSL_VERIFY_SERVER_CERT option of the client API) when used together with –ssl will ensure that the established connection is SSL-encrypted and the MariaDB server has a valid certificate. This fixes CVE-2015-3152.
  • Crashing Bug: mysql_upgrade crashes the server with REPAIR VIEW (MDEV-8115).
  • Crashing Bug: Server crashes in intern_plugin_lock on concurrent installing semisync plugin and setting rpl_semi_sync_master_enabled (MDEV-363).
  • Crashing Bug: Server crash on updates with joins still on 10.0.18 (MDEV-8114).
  • Crashing Bug: Too large scale in DECIMAL dynamic column getter crashes mysqld (MDEV-7505).
  • Crashing Bug: Server crashes in get_server_from_table_to_cache on empty name (MDEV-8224).
  • XtraDB upgraded to 5.5.42-37.2
  • TokuDB upgraded to 7.5.7

Given the security fix, you may want to review the CVE to see if this is something you need to address. Also, please review the crashing bugs to see if they might affect you, and upgrade if so. Also, if running TokuDB or XtraDB, you may also want to benefit from those fixes, as well as the new MariaDB fixes (59 in all).

MariaDB 5.5.43 Overview and Highlights

MariaDB 5.5.43 was recently released (it is the latest MariaDB 5.5), and is available for download here:

https://downloads.mariadb.org/mariadb/5.5.43/

This is a maintenance release, and so there were not too many major changes, but definitely a few worth mentioning, as well as one *important* caution:

  • Security Fixes: Fixes for the following security vulnerabilities:
  • Deprecation Notice: As per the MariaDB Deprecation Policy, this will be the final release of MariaDB 5.5 for Fedora 19 “Schrödinger’s Cat”, Ubuntu 10.04 LTS “Lucid”, and Mint 9 LTS “Isadora”. When the next version of MariaDB 5.5 is released, repositories for these distributions will go away.
  • Includes all bugfixes and updates from MySQL 5.5.43 (MySQL 5.5.43 Overview and Highlights)
  • TokuDB upgraded to 7.5.6
  • XtraDB upgraded to 5.5.42-37.1
  • Important mysql_upgrade Caution: The mysql_upgrade in this version introduced a serious bug which affects mysql_upgrade. If already running a MariaDB 5.5.x version, then you can safely skip running mysql_upgrade. However, if migrating from MySQL to MariaDB 5.5, then note this bug. For this specific bug, the problem appears if the targeted databases include data structures such as views with binary or text blobs. The malfunction is in the REPAIR VIEW statement which the script calls.
    • The fix will appear in MariaDB 5.5.44, which will be available soon (MariaDB 5.5.44 includes all MySQL 5.5.44 fixes, so it will be available very shortly after MySQL 5.5.44 is released).

Given the security fixes, you may want to review the CVEs to see if this is something you need to address. Also, if running TokuDB or XtraDB, you may also want to benefit from those fixes, as well as the new MariaDB fixes. However, if you plan on migrating from MySQL, if the above bug is relevant to you, then you should either upgrade to MariaDB 5.5.42, wait for 5.5.44, or possibly upgrade to MariaDB 10.0 (10.0.19 also contains the fix).

MariaDB 5.5.42 Overview and Highlights

MariaDB 5.5.42 was recently released (it is the latest MariaDB 5.5), and is available for download here:

https://downloads.mariadb.org/mariadb/5.5.42/

This is a maintenance release, and so there were not too many changes at all and only 3 changes (enhancements) I felt noteworthy:

  • The new version of the Audit Plugin is 1.2 is included with the following new features:
    • In the audit log passwords are now masked, i.e. the password characters are replaced with asterisks.
    • It’s now possible to filter logging to include only DDL (CREATE, ALTER, etc.) or DML (INSERT, UPDATE, etc.) statements.
    • For more information please refer to the About the MariaDB Audit Plugin page. The plugin is disabled by default.
  • With this release we introduce a low-level Client API. Applications, linked with libmysqlclient client library can use these functions to read and parse raw protocol packets:
    • unsigned long mysql_net_read_packet(MYSQL *mysql);
    • unsigned long mysql_net_field_length(unsigned char **packet);
  • Includes all bugfixes and updates from MySQL 5.5.42 (MySQL 5.5.42 Overview and Highlights)
  • TokuDB upgraded to 7.5.5

So there are no real crucial fixes requiring an upgrade, however, if you’re running the audit plugin, or TokuDB, or you want the benefits of the new fixes in general, then you should consider an upgrade.

MariaDB 5.5.37 was recently released (it is the latest MariaDB 5.5), and is available for download here:

https://downloads.mariadb.org/mariadb/5.5.37/

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 few items worth mentioning:

  • The MariaDB Audit Plugin now included.

Given the number of InnoDB and XtraDB fixes (in 5.5.37 and 5.5.36 respectively), if you are using InnoDB or XtraDB+ in MariaDB 5.5, then I would definitely recommend upgrading to MariaDB 5.5.37.

MariaDB 5.5.36 Overview and Highlights

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 not see reports of the same issues in 5.5.35, so perhaps that covered it, or at least the majority. 5.5.34 had the worst of this bug, so if you are running 5.5.34, then I *would* definitely recommend upgrading.

Additionally, if you are using MySQL’s InnoDB in MariaDB, then I would definitely recommend upgrading to MariaDB 5.5.36 as well.
