How MariaDB Server is tested
MariaDB Foundation is commited to ensuring MariaDB Server has a thriving community of developers and contributors. A software project cannot be maintained without proper tests. mysql-test-run is our standard testing toolkit for MariaDB Server. What it (mostly) does is run queries against one or more servers and compare their output to the expected one. This checks both behaviour and data consistency. The main principle is the server should always return the same data that is put into it.
One problem with this testing method is that it only covers the hosts’ environment. That means that if you are running Debian on x86_64 architecture, you are testing x86_64 architecture on a Debian Linux distribution. Read more

At MariaDB Foundation, we are proud of MariaDB Server getting plenty of contributions. But we don’t want to get cocky, so here is an update about where we stand, and what we want to make happen.
First, we have shown our contribution pride in several places. On 15 February 2019, I tweeted
On code contributions, #MariaDB beats #MySQL 1009 to 247: We have over a thousand (1009) closed pull requests on github (and 179 open), MySQL has 247 closed (1 open). https://t.co/32NIuMMTvc pic.twitter.com/ZZcRBdk939

Repeating: On code contributions, #MariaDB beats #MySQL 1009 to 247: We have over a thousand (1009) closed pull requests on GitHub (and 179 open), MySQL has 247 closed (1 open).
In our Annual Report 2018, we spent several pages, talking about pull requests and patches, showing code contribution statistics. Read more
MariaDB Server 10.4 came with a whole lot of Security related changes. Some of them are merely optimizations (like MDEV-15649), some improve existing features to be more robust (MDEV-15473, MDEV-7598) or convenient (MDEV-12835, MDEV-16266). Some are MySQL compatibility features, requested by our users (MDEV-7597, MDEV-13095).
But the first thing any MariaDB Server user, whether an experienced veteran or a newbie, does — before even issuing the first SQL statement — is logging in. Authenticating to the database server. Read more
Software licensing is a difficult subject that we don’t usually want to think about. It can be confusing and frustrating trying to work out whether different licenses are compatible, and problems like dual-licensing make it even harder. We all just want to write great code, not worry about licenses!
Until now, contributors who provide improvements and bug fixes to MariaDB have been asked to declare their license choice every time they make a contribution. For new contributors, or those who just want to submit a very small fix, this can be a complicated extra step they weren’t expecting. For regular contributors, it’s extra work for every single pull request. Read more
February in New York City is again MariaDB time, and the first MariaDB Developers Unconference of 2019 will take place on Saturday 23 and Sunday 24 February, with Hudson River Trading as kind hosts.
The event is free to attend and you can join for the entire weekend, or as little time as you wish. However, it is essential to sign up in advance on the event page at Meetup.com.
The schedule of this unconference is being drafted in a public spreadsheet. Please add suggestions for sessions you would like to present or lead on this spreadsheet. Read more
Virtualisation has been a very popular technique for both development and production systems for many years. It allows multiple software environments to run on the same physical machine.
Containerisation takes this idea even further. It allows you to segment your software environment down to the level of individual software packages. This means you can install multiple copies of MariaDB on one system, and run them in parallel while keeping them isolated from each other.
This is a very powerful technique when doing development because you can quickly test different versions of the software. It also allows you to experiment with clusters: you can create a complete Galera database cluster on a single computer! Read more
