Disappearing test cases or did another part of MySQL just become closed source?
About a week ago I was looking at MySQL 5.5.27, and noticed a curious thing. Despite the fact that the new MySQL release contained its usual share of bug fixes, not a single one of them was accompanied with a test case.
Now, let me tell you something about tests. For many years MySQL was using its own testing framework, called mysql-test. The first version was written as early as 1999. Over the years it has accumulated a lot of […]

Explanation on MariaDB 10.0
In end of May I told about the numbering plans for the next version of MariaDB in the blog post What comes in between MariaDB now and MySQL 5.6?. We received quite a lot of feedback and criticism on the idea of calling the next version MariaDB 10.0. Here is a little more information about why it makes sense to call the next version 10.0.
This is not news for most of you. MariaDB is not just a set of […]

The Query Cache and Partitions
Like others we were not satisfied with the fix for a bug in MySQL which caused the query cache and partitioning to not work reliably together. The bug, in simple terms, was that if the query cache was enabled and you used partitioned tables and if a partitioned table was using a transactional engine like InnoDB or XtraDB, the query cache could, under certain circumstances, return incorrect results.
Returning incorrect results is a definite, high-priority bug. However, the upstream fix was to disable all caching of queries from […]

Meet us at OSCON
Things are definitely a little quieter here in MariaDB land as many people embark on summer vacations to rest and recharge. However we will be at OSCON 2012. We have a booth in the non-profit/projects pavilion, amazing amounts of schwag, and the famous black vodka that Monty always brings with him. We plan to have a BoF on Thursday evening (come to D135 at 8pm), and we will be at the MySQL BoF on Wednesday evening as well, just for […]

Consolidating MariaDB project tools
It is not a secret that we’ve been kicking the tires and playing with JIRA for project management. After using it since the beginning of the year most of us like the feel of it and we’ve decided that it makes sense to start using it more.
As you know, the MariaDB project has many fragmented resources. We report bugs in Launchpad. We store our plans in worklog. We’ve never used the Launchpad Blueprint feature for this very reason. We […]

Monty Program & SkySQL: a statement on the serious security vulnerability that was found in MariaDB and MySQL
Over the past few days extensive conversations around a new security vulnerability in MariaDB and MySQL have taken place.
It all started as a chain reaction when Monty Program publicly disclosed information about the flaw they had found and about how to make sure your MariaDB and MySQL installations can be fixed. The initial information got assigned the security vulnerabitlity identifier CVE-2012-2122 and the contents can be seen e.g. here http://seclists.org/oss-sec/2012/q2/493.
The bug was found two months ago on April […]

MariaDB 5.5 performance on Windows
We haven’t posted any Windows benchmarks for a while, and MariaDB for Windows contains some specific improvements which might not be widely know since we haven’t talked much about them yet. This post is an attempt to fix that. We’ll also share current MySQL 5.5 numbers.
My setup is an 8 core 2 socket server (yes, a little bit dated for today, but it is the best machine I have at my disposal), 10K SAS disks with RAID1. I ran sysbench 0.4 […]
