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.

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;

I’m going to start this blog post by saying that I made a mistake, a mistake that means all of the metrics blog posts so far have been made with erroneous data. As part of our openness value I will give a post-mortem of the issue here.
Metrics generation
Before we look into what went wrong, I first need to give a bit of background. The commit metrics are generated using a tool called “gitdm”, this is a “Git Data Miner” that was designed to generate commit statistics for the Linux Kernel. Our fork of this is in the metrics repository which includes some customisations that fit MariaDB Server’s needs better.

Yes, it is a bit of a click-bait title, but in this case running one SQL command did improve a community user’s performance by that much. It could help you too.
The story
A community user posted in a couple of places that when migrating a large WordPress installation to MariaDB that they were seeing a certain query performing terribly. The query was taking 1.5 seconds to execute and it was clear from the explain plan that the optimizer was not making an ideal decision about the join order.
The query was generated by WordPress so it would not be easy to force an index, or rewrite the query.

Last month we provided contributor statistics for the last few years. We have had some fantastic feedback from this so today we are presenting you with another drop of contributor statistics for the last month. Normally we would be doing these quarterly but there are so many extra things to report that we decided to do a bonus one now.
Some key things have happened in the last month which affect the data, the first is that MariaDB 10.11 has had a preview release. Which means there has been a flurry of activity around this.

The MariaDB Foundation will be hosting a Server Fest on Thursday 17 November 2022. This time it’ll be a hybrid event, harnessing the energy that comes from many of the participants being present in person.
To encourage interaction, the event will be streamed live, but will not immediately be made available online, so don’t miss out on this opportunity to interact with the speakers and MariaDB members in person!
The keynote speaker will be Wikimedia Foundation’s Manuel Arostegui. The schedule and further details will be announced soon.
We start at 14:00 Paris time (CET) – 8:00am New York, 20:00 Beijing.

Our most recent MariaDB Server release introduced some regressions starting with the 10.6 series, affecting 10.7 – 10.9 as well. This blog post is here to explain the problems in hopes that the impact is minimized. We are likely going to release a new version of MariaDB correcting these problems soon.
InnoDB Full Text Index on tables causes an assertion error (MDEV-29342)
There was a bug in the InnoDB Storage Engine where the full text index could go out of sync with the actual table data. This would happen when only one new row was inserted between the last InnoDB sync (which happens asynchronously) and a server shutdown.

In the last meeting, the MariaDB Foundation Board proposed the regular publishing of contribution statistics. This post is an update on our progress and the first report.
