[H3] Vibe-coding an Audit Plugin in Under 3 Minutes
Who says developing MariaDB plugins is hard? I was able to produce one in under 3 minutes!
I of course did it by asking Grok nicely:
The produced result is actually very decent:
It even produced a Makefile:
And compilation instructions:
While I had Grok’s attention I’ve given it a follow up task:
Note the “please” …

errorwatch.c – MariaDB Audit API plugin
Records statement execution errors into a dedicated log file.
This plugin subscribes to the GENERAL audit class and logs
events of type MYSQL_AUDIT_GENERAL_ERROR (and STATUS events
that carry a non-zero error code). It writes structured
entries to /var/log/mariadb/errorwatch.log (or /tmp/ fallback).
To build (inside MariaDB source tree):
1. Copy this file and CMakeLists.txt to plugin/errorwatch/

MariaDB Foundation is pleased to announce the publication of our first MariaDB Server Solution Stack in the MariaDB Server Ecosystem Hub:
Privacy-First Stack: Nextcloud, Passbolt, and MariaDB Server
This stack brings together three open-source technologies with a shared purpose: helping organizations build collaboration infrastructure around privacy, control, and long-term digital sovereignty.
The stack combines:
Nextcloud for file sharing, synchronization, and collaboration
Passbolt for password, credential, and secrets management
MariaDB Server as the open-source relational database layer at the core
Together, they form a practical architecture for organizations that want to keep collaboration data, credentials, and structured data under their own control.

To help you see your contributions successfully merged into the MariaDB Server codebase I’ve compiled a comprehensive description of the contribution process itself, the roles involved into it, the sequence of actions and conditions for transition from one to another.

Please go to COMMUNITY_CONTRIBUTIONS.md.
This of course is going to be a moving target! I fully intend to keep the document up to date and enhance it with clarifications and process changes as they happen.

One of the corner stones in MariaDB Foundation’s mission is:
We strive to increase adoption by users and across use cases, platforms and means of deployment.
https://mariadb.org/about/
MariaDB Server plugins are definitely a prime “means of deployment” for server features. But a relatively neglected one so far. They have been around for many years. But, somehow, they have escaped the user’s focus. Why that happened is a very interesting topic. And one that I’d definitely like to hear your opinion on!
Which brings me to my main topic: How do we all change that?

We are concluding our series related to new data types using the Type_handler framework, with some limitations that are not yet covered by the framework:
No custom indexing methods. A plugin type cannot introduce a new indexing method.
No custom hashing. Plugin types can’t provide their own function for hash-based operations. Things like MEMORY table indexes, GROUP BY, and partitioning fall back to the underlying type’s hash.
No new field attributes. Plugin types cannot define custom attributes beyond the existing ones: length, precision, scale, and GIS SRID.

This is part 4 of a series related to extending MariaDB with a custom data type using the Type_handler framework.

In the previous examples, our MONEY data type inherits from DOUBLE and then we override some methods.

As you know, MySQL-Sandbox and then dbdeployer have always been part of the Swiss Army knife for DBAs trying to evaluate, test, or reproduce issues with a certain version of their database.
The author, Giuseppe Maxia, aka the datacharmer, produced incredible work on these two projects. Unfortunately, Giuseppe decided to archive the project in 2023. Read the announcement.
But finally, someone has decided to take up the torch. ProxySQL announced this big decision last month.
We at the MariaDB Foundation are very happy that dbdeployer has risen from the ashes thanks to the ProxySQL team, and we are committed to further developing and contributing to this great tool for all its users, especially those who use it to deploy MariaDB Server.

In the previous article, we wrote, compiled, and tested our first custom data type for MariaDB using the Type_handler framework.
But currently, aside from allowing the use of its new name (MONEY) and listing it in the metadata, our new data type behaves exactly like a DOUBLE, the class it inherits from.
In this article, we will extend our data type just a bit by transforming the result into a VARCHAR and adding a currency sign to it: the dollar sign ($).
This is the expected result:
MariaDB [test]insert into t1 (amount) values (41578.4); …

MariaDB Server is an Open Source project that thrives thanks to its community. MariaDB Foundation handles all community contributions in a timely manner. There are many ways to contribute to MariaDB Server. We welcome documentation changes and additions, as well as code contributions to all repositories under our GitHub Repository. Additionally you can help grow the community by answering questions on DBA Stack Exchange, StackOverflow, Reddit, Quora and others. You can also vote on our polls and help us better understand the community’s needs.
Our preferred communication channels are Zulip, and the mailing lists:
For discussions about development of MariaDB Server: maria-developers
For discussions about using MariaDB Server and all other topics: maria-discuss
For discussions about MariaDB Server and tools documentation: maria-docs
Most MariaDB Server developers are located in Europe, so the likely time to get immediate answers is during Europe business hours. However, feel free to drop a message anytime and it is very likely someone will answer soon!
[H2] Contribute code
As an Open Source Database, MariaDB Server follows a process simillar to most open source projects when it comes to contributing code. We prefer contributions in the form of pull requests on Github. There are a number of articles that describe the process in detail.
How to get the code, build it and run tests
How to create a pull request for MariaDB Server
How to write good test cases for MariaDB Server
Licensing and the MCA
The basic principles however can be summarized as follows:
Make sure your pull request clearly explains what it is trying to achieve.
Make sure that your code is tested. You can make use of the automatic buildbot checks to see if your code passes a basic smoke test.
Make sure the correct licensing agreement for your code is given.
Follow up on reviews from core developers or other community members and do not be afraid to disagree. The key point is to keep the discussion technical.
Aside from regular pull requests, MariaDB Foundation has participated in Google Summer of Code since 2013, with many features making their way into the main server.

Beginner Friendly Bugs
[H2] Packaging
MariaDB Server aims to be available to everyone on all possible platforms and we welcome contributions related to the effort.
Introduction to packaging
[H2] Contribute documentation
A software project is only as good as its documentation. MariaDB Foundation aims to maintain the best possible documentation. The MariaDB Documentation is free for the community to contribute. If you spot a mistake, feel free to correct it. The MariaDB Foundation has prepared special tutorials for different kinds of contributions:
General documentation contribution tutorial
Documentation style guide
Additionally, MariaDB Foundation has announced a University Program, where universities can share their course material and publish it under a free license.
[H2] Contribute to testing
MariaDB Server has historically relied on the community for feedback and to supplement the in-house QA process. The easiest way to contribute to MariaDB Server is to try out our development releases. Offer us feedback as soon as possible so we can spot bugs early and improve quickly. Our roadmap and bugs database is hosted at jira.mariadb.org. All bug reports get attention and help keep MariaDB Server a robust, reliable and performant database. Feature requests are also welcome.
File a bug or feature request
Enable the Feedback Plugin and see what information is collected in the usage statistics
MariaDB Server and related tools are tested thoroughly within our buildbot infrastructure. A complete testing system is necessary for a project to continue. buildbot.mariadb.org has made it easy to contribute computing resources to our system.
