MariaDB Server Compatibility with MySQLColin Charles
At the MariaDB Server Developer's meeting in Amsterdam, Oct 8 2016. This was the deck to talk about what MariaDB Server 10.1/10.2 might be missing from MySQL versions up to 5.7. The focus is on compatibility of MariaDB Server with MySQL.
Presented at Percona Live Amsterdam 2016, this is an in-depth look at MariaDB Server right up to MariaDB Server 10.1. Learn the differences. See what's already in MySQL. And so on.
Securing your MySQL / MariaDB Server dataColin Charles
Co-presented alongside Ronald Bradford, this covers MySQL, Percona Server, and MariaDB Server (since the latter occasionally can be different enough). Go thru insecure practices, focus on communication security, connection security, data security, user accounts and server access security.
Presented at the MySQL Chicago Meetup in August 2016. The focus of the talk is on backups and verification, replication and failover, as well as security and encryption.
Failure happens, and we can learn from it. We need to think about backups, but also verification of them. We should definitely make use of replication and think about automatic failover. And security is key, but don't forget that encryption is now available in MySQL, Percona Server and MariaDB Server.
MariaDB Server & MySQL Security Essentials 2016Colin Charles
This document summarizes a presentation on MariaDB/MySQL security essentials. The presentation covered historically insecure default configurations, privilege escalation vulnerabilities, access control best practices like limiting privileges to only what users need and removing unnecessary accounts. It also discussed authentication methods like SSL, PAM, Kerberos and audit plugins. Encryption at the table, tablespace and binary log level was explained as well. Preventing SQL injections and available security assessment tools were also mentioned.
This is my third iteration of the talk presented in Tokyo, Japan - first was at a keynote at rootconf.in in April 2016, then at the MySQL meetup in New York, and now for dbtechshowcase. The focus is on database failures of the past, and how modern MySQL / MariaDB Server technologies could have helped them avoid such failure. The focus is on backups and verification, replication and failover, and security and encryption.
MySQL is a unique adult (now 21 years old) in many ways. It supports plugins. It supports storage engines. It is also owned by Oracle, thus birthing two branches of the popular opensource database: Percona Server and MariaDB Server. It also once spawned a fork: Drizzle. Lately a consortium of web scale users (think a chunk of the top 10 sites out there) have spawned WebScaleSQL.
You're a busy DBA having to maintain a mix of this. Or you're a CIO planning to choose one branch. How do you go about picking? Supporting multiple databases? Find out more in this talk. Also covered is a deep-dive into what feature differences exist between MySQL/Percona Server/MariaDB/WebScaleSQL, how distributions package the various databases differently. Within the hour, you'll be informed about the past, the present, and hopefully be knowledgeable enough to know what to pick in the future.
Note, there will also be coverage of the various trees around WebScaleSQL, like the Facebook tree, the Alibaba tree as well as the Twitter tree.
An introduction to MongoDB from an experienced MySQL user and developer. There are differences and we go thru the What/Why/Who/Where of MongoDB, the "similarities" to the MySQL world like storage engines, how replication is a little more interesting with built-in sharding and automatic failover, backups, monitoring, DBaaS, going to production and finding out more resources.
Having spent more than the last decade being the main point of contact for distributions shipping MySQL, then MariaDB Server, it's clear that working with distributions have many challenges. Licensing changes (when MySQL moved the client libraries from LGPL to GPL with a FOSS Exception), ABI changes, speed (or lack thereof) of distribution releases/freezes, supporting the software throughout the lifespan of the distribution, specific bugs due to platforms, and a lot more will be discussed in this talk. Let's not forget the politics. How do we decide "tiers" of importance for distributions? As a bonus, there will be a focus on how much effort it took to "replace" MySQL with MariaDB.
Benefits: if you're making a distribution, this is the point of view of the upstream package makers. Why are distribution statistics important to us? Do we monitor your bugs system or do you have a better escalation to us? How do we test to make sure things are going well before release. This and more will be spoken about.
As an upstream project (package), we love nothing more than being available everywhere. But time and energy goes into making this is so as there are quirks in every distribution.

MariaDB in Debian and Ubuntu: The next million usersOtto Kekäläinen
MariaDB is poised to become the default database package for Debian and Ubuntu distributions, which account for 60% of web servers. With over 300 million servers that could run the simple command 'apt-get install mariadb-server', MariaDB has the potential to gain many new users by being the default package. MySQL may be removed entirely from the next Debian release, with a Debian security team member confirming MariaDB 10.0 was chosen as the single database version for the upcoming Debian "stretch" release. MariaDB has fewer open bugs than MySQL in the Debian bug tracking system, further strengthening the case for it to become the primary database package.

WordPress Security 101 – WordCamp Finland 2016 presentation by Otto Kekäläine...Otto Kekäläinen
The document discusses security best practices for WordPress sites. It defines information security as confidentiality, integrity and availability. The biggest risks are from leaked passwords and software vulnerabilities. For passwords, it recommends strong unique passwords, HTTPS for all connections, and using captchas. For software, it advises minimizing plugins/themes, only installing from trusted sources, and keeping everything updated. It warns that plugins pose the largest risk and provides an example of a breach through an outdated plugin. Regular backups that are automated, complete, frequent and stored offsite are also important for recovery from failures or attacks. The key is following password hygiene, updating software, using HTTPS, installing from trusted sources, and having backups in place.
Find WordPress performance bottlenecks with XDebug PHP profilingOtto Kekäläinen
XDebug is a tool that allows developers to profile PHP applications to identify bottlenecks and anomalies. It works by instrumenting PHP code during execution and collecting metrics on runtime performance. The document provides instructions on installing XDebug, taking profiling samples of a WordPress site, and analyzing the results with Webgrind to identify expensive functions and optimize performance. With repeated profiling and analysis, developers can pinpoint specific code causing issues and refactor it for better efficiency.
Testing and updating WordPress - Advanced techniques for avoiding regressionsOtto Kekäläinen
This document discusses techniques for safely updating WordPress core and plugins to avoid regressions. It recommends setting up a "shadow" test site to first update and thoroughly regression test plugins and themes before deploying updates to the production site. Integration tests can automate aspects of regression testing by programmatically interacting with and validating the site. Visual regression testing can additionally detect layout or design changes. While most updates can be safely automated, some human oversight is still important to determine if changes constitute failures.
Less passwords, more security: unix socket authentication and other MariaDB h...Otto Kekäläinen
This document discusses securing MariaDB installations through socket authentication and user account management. It recommends configuring MariaDB to use socket authentication for the root user instead of passwords to eliminate the need for root password management across servers. It also recommends creating individual user accounts with passwords for applications instead of shared accounts, restricting MariaDB to only listen on localhost, encrypting connections using SSL, and encrypting data at rest. The document provides configuration examples for implementing these recommendations in MariaDB.
This document provides best practices and guidelines for using Git version control. It discusses topics such as why version control is important, how to write good commit messages, reviewing code changes, using branches, and more. The key recommendations are to focus commit messages on the why rather than what changed, get code reviews on the master branch, and never force push to master to avoid diverging versions.
Presentation given at the WP Jyväksylä Meetup March 21st, 2017. This revised version contains references to the WordPress security news that circulated in February 2017.

Search in WordPress - how it works and howto customize itOtto Kekäläinen
WordPress search customization is a topic we at Seravo get asked about on a frequent basis. There are many different ways to customize the search, and customers understandably want to learn the best practices. The search can be customized quite easily with small changes on PHP code level, and by utilizing MariaDB database’s built-in search functionality.

DebConf 2020: What’s New in MariaDB Server 10.5 and Galera 4?Otto Kekäläinen
MariaDB has now reached the 10th major release since the original authors of MySQL started taking the code base in another direction than where MySQL is going under Oracle’s ownership. Today MariaDB has many more features than Oracle MySQL and it is the default MySQL variant in Debian.
This presentation covers what new features landed in MariaDB 10.5 and also touches on how the long existing features have evolved to today, and naturally what is their state and best practices for Debian users. MariaDB has also built-in support for Galera master-master replication and Galera 4 has recently landed in Debian, so it will also be covered.

How MariaDB packaging uses Salsa-CI to ensure smooth upgrades and avoid regre...Otto Kekäläinen
This document discusses how MariaDB in Debian uses the Salsa-CI/Gitlab-CI infrastructure to ensure smooth upgrades and avoid regressions. It describes how the MariaDB packaging repositories were moved to Salsa.Debian.org and how a custom Gitlab-CI pipeline with 18 jobs over 5 stages was created to build, test, and simulate upgrades from various versions. This comprehensive continuous integration process helps catch issues early and improve the quality and reliability of MariaDB upgrades. Challenges in testing such a large and complex package are also discussed.
This document discusses the state of MariaDB and MySQL packaging in Debian. MariaDB 10.3 is included in the latest stable Debian release, and 10.4 will be uploaded soon. MySQL 5.7 is available in unstable but not stable releases. There is ongoing work to maintain older MariaDB versions and develop new packages. Contributors are encouraged to participate in bug triage and discussions to help address stale bugs without coding skills.

How to investigate and recover from a security breach in WordPressOtto Kekäläinen
This document summarizes Otto Kekäläinen's talk about investigating and recovering from a WordPress security breach at his company Seravo. On November 9th, 2018 four WordPress sites hosted by Seravo were compromised due to a vulnerability in the WP GDPR Compliance plugin. Seravo's security team launched an investigation that uncovered malicious user accounts, identified the vulnerable plugin as the entry point, and cleaned up the sites. The experience highlighted the importance of having an incident response plan even when security best practices are followed.

Improving WordPress Performance with Xdebug and PHP ProfilingOtto Kekäläinen
Presentation given at WordCamp Europe 2017 in Paris 2017-06-16.
Xdebug is a tool for developers to gain insight into how PHP is executed. Using it for profiling is a very effective, fast and precise method to find bottlenecks in your WordPress site. In this talk I explain how to use it with Webgrind, how to find potential optimization targets, show examples of real cases when Xdebug helped fix a performance problem and also explain what Xdebug is not suitable for and what can be used instead. If you are not a developer, you’ll learn what Xdebug is capable of and when to ask a developer to use it.
The document discusses plans for MySQL and MariaDB packages in Debian. It notes that MariaDB will become the default over MySQL. It provides a list of tasks for improving the MariaDB packages, including adding tags, optional feedback plugins, systemd scripts, and autopkg tests. It also discusses some more difficult tasks such as reproducible builds and using an open-source SSL library instead of the bundled YaSSL.
Not So Common Memory Leaks in Java WebinarTier1 app
This SlideShare presentation is from our May webinar, “Not So Common Memory Leaks & How to Fix Them?”, where we explored lesser-known memory leak patterns in Java applications. Unlike typical leaks, subtle issues such as thread local misuse, inner class references, uncached collections, and misbehaving frameworks often go undetected and gradually degrade performance. This deck provides in-depth insights into identifying these hidden leaks using advanced heap analysis and profiling techniques, along with real-world case studies and practical solutions. Ideal for developers and performance engineers aiming to deepen their understanding of Java memory management and improve application stability.

TestMigrationsInPy: A Dataset of Test Migrations from Unittest to Pytest (MSR...Andre Hora
Unittest and pytest are the most popular testing frameworks in Python. Overall, pytest provides some advantages, including simpler assertion, reuse of fixtures, and interoperability. Due to such benefits, multiple projects in the Python ecosystem have migrated from unittest to pytest. To facilitate the migration, pytest can also run unittest tests, thus, the migration can happen gradually over time. However, the migration can be timeconsuming and take a long time to conclude. In this context, projects would benefit from automated solutions to support the migration process. In this paper, we propose TestMigrationsInPy, a dataset of test migrations from unittest to pytest. TestMigrationsInPy contains 923 real-world migrations performed by developers. Future research proposing novel solutions to migrate frameworks in Python can rely on TestMigrationsInPy as a ground truth. Moreover, as TestMigrationsInPy includes information about the migration type (e.g., changes in assertions or fixtures), our dataset enables novel solutions to be verified effectively, for instance, from simpler assertion migrations to more complex fixture migrations. TestMigrationsInPy is publicly available at: https://github.com/altinoalvesjunior/TestMigrationsInPy.
What Do Contribution Guidelines Say About Software Testing? (MSR 2025)Andre Hora
Software testing plays a crucial role in the contribution process of open-source projects. For example, contributions introducing new features are expected to include tests, and contributions with tests are more likely to be accepted. Although most real-world projects require contributors to write tests, the specific testing practices communicated to contributors remain unclear. In this paper, we present an empirical study to understand better how software testing is approached in contribution guidelines. We analyze the guidelines of 200 Python and JavaScript open-source software projects. We find that 78% of the projects include some form of test documentation for contributors. Test documentation is located in multiple sources, including CONTRIBUTING files (58%), external documentation (24%), and README files (8%). Furthermore, test documentation commonly explains how to run tests (83.5%), but less often provides guidance on how to write tests (37%). It frequently covers unit tests (71%), but rarely addresses integration (20.5%) and end-to-end tests (15.5%). Other key testing aspects are also less frequently discussed: test coverage (25.5%) and mocking (9.5%). We conclude by discussing implications and future research.

Scaling GraphRAG: Efficient Knowledge Retrieval for Enterprise AIdanshalev
If we were building a GenAI stack today, we'd start with one question: Can your retrieval system handle multi-hop logic?
Trick question, b/c most can’t. They treat retrieval as nearest-neighbor search.
Today, we discussed scaling #GraphRAG at AWS DevOps Day, and the takeaway is clear: VectorRAG is naive, lacks domain awareness, and can’t handle full dataset retrieval.
GraphRAG builds a knowledge graph from source documents, allowing for a deeper understanding of the data + higher accuracy.
