Gcov is a coverage testing tool, used to create better programs. It can show which parts of the codebase are untested. Gcov is located in the same package as gcc. MariaDB takes care of code quality and checks test coverage with Gcov. We are looking forward to have Gcov used soon as a part of our buildbot (MDBF-158).
How to use Gcov
Let’s write a demo example to demonstrate how it works.
— Source code:
$ cat -n test.c
int f1()
{
return 0; …
I’ve mentioned in past blog posts that not every contribution is a code contribution. There are many possible contributions that are valuable, including testing, bug reports, helping the community, etc.
Non-code contributions are quite invisible
Unfortunately, non-code contributions are sometimes invisible to the wider community, so today I wanted to shine a light on some such contributions. In this case, contributions made by one of our sponsors, Intel.
Intel is open source friendly
Intel have been an open source friendly company for a long time. But have recently pushed harder than ever towards open source, even giving their first ever new Innovation Award to Linus Torvalds.

With MariaDB 10.0.0 having been released over ten years ago (12 Nov 2012), you may ask yourself when there will be MariaDB 11.0.0. If so, I can answer you: Today.
You can now download MariaDB Server 11.0 Alpha preview from our dedicated download page and check out the release notes.
Time has passed …
Of course, we have a better reason for going with a new first number in a release other than ten years having passed. Significant new features. Significant incompatibilities with earlier versions.

One of the most straightforward ways to add functionality to MariaDB or MySQL server instances is by creating a user-defined function (UDF). These are compiled functions loaded from dynamic binaries that can be much more performant and flexible than what can be written in SQL, providing the same capabilities as builtin functions.
These UDFs are typically written in C or C++, but a library is now available that makes it easy to write them in Rust. This blog discusses some of the reasoning for writing this library, followed by a very basic usage example that doesn’t require any experience with the language.

It may be long overdue, but based on recent events, we have launched Code of Conduct project at MariaDB Foundation. Our aim is to get your feedback and define a CoC, ideally by end of January, if we see convergence.
In the meantime, if we see unacceptable behaviour on the MariaDB mailing list or elsewhere, we will take action. We want to extend our apology to those who have had unpleasant experiences, about which we have done nothing in the past.
As for the code of conduct wording, our goal is to keep it short. Lofty goals often trigger distractive debates;

Today, MariaDB Corporation announced that it completed its merger, landing on NYSE as “MRDB”. With MariaDB Corporation being our founding member as well as our primary code contributor, we want to congratulate what is now MariaDB plc for this remarkable achievement.
Joint goals
MariaDB Foundation and MariaDB Corporation, while independent entities, share a joint interest in the development and adoption of MariaDB Server. In the new scenario with what is now to be referred to as MariaDB plc being a publicly traded company, we expect further interest in MariaDB Server by the ecosystem and community.

Important news: MariaDB 10.11, which just was declared RC, is a long-term maintenance version. The industry standard term to refer to that concept is LTS (as in long-term support), and we too use this term for the releases that get a significantly longer lifetime of bug fixes.
We are announcing MariaDB 10.11 as LTS for a number of reasons:
Firstly, the purpose of an LTS is to reassure users – and, in particular, Linux distros – that a certain version will receive regular updates long-term, for the lifetime of their product.
…
The MariaDB Foundation is pleased to announce the availability of MariaDB 10.11.1, the first release candidate in the MariaDB 10.11 series, and MariaDB 10.10.2 the first generally available release in the short-term MariaDB 10.10 series.
See the release notes and changelogs for details.
