  • For this episode, Fred and Scott are joined by Laurynas Biveinis - one of the most prolific individual contributors to MySQL Community. Take a listen as Laurynas discusses the process he uses when he discovers bugs and how he sets up tests for the engineering team. ----------------------------------------------------------- Episode Transcript: 00;00;09;14 - 00;00;36;00 Unknown Welcome to Inside MySQL: Sakila Speaks, a podcast dedicated to all things MySQL. We bring you the latest news from the MySQL team, MySQL project updates and insightful interviews with members of the MySQL community. Sit back and enjoy as your hosts bring you the latest updates on your favorite open sourcedatabase. Let's get started! Hello and welcome to Sakila Speaks, the podcast dedicated to MySQL. 00;00;36;07 - 00;01;13;06 Unknown I am leFred and I'm Scott Stroz. Today we are thrilled to welcome Laurynas Biveinis to our podcast. Laurynas. He's a highly respected software engineer and a seasoned expert in database technologies, particularly MySQL. With a rich background in database internals, performance optimization and open source development. Laurynas has contributed extensively to the MySQL ecosystem. He has played a key role in announcing most performance and reliability to his work on project like the Percona server and other database innovation. 00;01;13;08 - 00;01;45;08 Unknown We are excited to dive into this highlight on MySQL, his evolution and the future of the database technology. Laurynas, you have been extremely active in helping improve MySQL and since April 2011, you have reported 444 bugs. First of all, I love the symmetry of the number of 444, but can you like, give us, a brief walkthrough of how you go about reporting the bugs? 00;01;45;08 - 00;02;00;25 Unknown Like, like what type of testing do you do? Do you set up some type of test framework or, or something? Because obviously, you know, you need to make sure that it can be repetitive and you have to report that stuff to, to the team. But just walk us through like your mental process that you, you, you do for that. 00;02;00;28 - 00;02;30;28 Unknown Hello. And, thanks for having me here. So to, to to answer the question about bug reporting. Whenever I notice that something is off, and I make a note of it, and I return to it later, and the majority of my bugs come from, either, documentation reading, either from the source code reading or from, running the source code, in the in a test framework. 00;02;31;00 - 00;02;52;18 Unknown So, the test framework gives something that, creates reproducible test cases. And if I can write one in the test case, in the, in the test framework, I do that and I submit that with a bug reports. And I know that your team immediately can, they can tell me whether they produce it or is, that they need something else for me. 00;02;52;21 - 00;03;20;04 Unknown So. So you are using MTR, as the the same framework as we do? Yeah. Most of the time I'm using MTR. So, but, so about all that, huge number of bugs that you report, you are also one of the most prolific contributors of my SQL with, 84 contributions in MySQL 8. So, why are you contributing so much and what type of contribution do you do usually for people that doesn't know you? 00;03;20;06 - 00;03;48;09 Unknown Well, so, these are usually bug fixes. Most of the time small but sometimes larger too. And over the years there have been a few performance features contributor to. So the thing I like about contributing is that,contribution makes that code less of my problem and more of your problem. So, it's like a gifting a puppy. 00;03;48;11 - 00;04;17;27 Unknown And so now you have to take care of it, although you are happy you received it. I love that analogy. That's a that's a that's a analogy about open source, contributions. That's great. So I've seen that you, recently have been blogging quite a bit about, MySQL and Mac OS, which interests me because for work I use, a mac and obviously I have to run MySQL on that platform. 00;04;18;00 - 00;04;48;15 Unknown But usually MySQL is run on Linux. That's a probably. Linux is probably the most popular operating system on which to run MySQL. Why do you think that is? Well, it's won the server wars. Hasn't it? And with the, the newer with the new features, with, with the BPF and you're in it's, it gets better every day and there is no real competition for it in the server space. 00;04;48;18 - 00;05;15;22 Unknown But the thing I love about Mac is that, development is easier for me on the Mac, and the hardware is very good. The build times are excellent on, on the on the Apple silicon machines. So I like that, I can do it with the least friction and with the, the best the turnaround time from typing to testing. 00;05;15;24 - 00...
