Fun with Bugs #42 - Bugs Fixed in MySQL 5.7.12

MySQL 5.7.12 was released more than 2 weeks ago. New features introduced there in a form of "rapid plugins" are widely discussed, but I am more interested in bugs reported by MySQL Community users that are fixed there. Unfortunately I do not see MySQL Community Release Notes by Morgan (like this) for quite a some time, so I have to continue describing key bug fixes and name people who reported and verified bugs in my "Fun with Bugs" series.

As usual, let's start with InnoDB bugs fixed:

  • Bug #80070 - "allocated_size and file_size differ if create general tablespace outside datadir". It was reported by my former colleague from Percona …

Building MariaDB 10.1.x and Galera from Source for Multiple Node Cluster Testing Setup

My Facebook followers probably noted that I quit from Percona some time ago and work for MariaDB since March 1, 2016. I changed the company, but neither the job role (I am still a Support Engineer), nor the approach to do my job. I still prefer to test everything I suggest to customers and I usually use software I build from source myself for these tests.

While I try to avoid all kinds of clusters as much as possible for 15 years or so already (it does not matter if it's Oracle RAC, MySQL Cluster or Percona XtraDB Cluster, all of them), it's really hard to avoid Galera clusters while working for MariaDB. One …

Docker MySQL Replication 101

In this blog post, we’ll discuss some of the basics regarding Docker MySQL replication. Docker has gained widespread popularity in recent years as a lightweight alternative to virtualization. It is ideal for building virtual development and testing environments. The solution is flexible and seamlessly integrates with popular CI tools.

 

This post walks through the setup of MySQL replication with Docker using Percona Server 5.6 images. To keep things simple we’ll configure a pair of instances and override only the most important variables for replication. You can add whatever other variables you want to override in the configuration files for each instance.

Note: the configuration described here is suitable for development or testing. We’ve also used the …

MySQL Contributions status

This post is an update to the status of various MySQL bugs (some with patches) that I’ve filed over the past couple of years (or that people around me have). I’m not looking at POWER specific ones, as there are these too, but each of these bugs here deal with general correctness of the code base.

Firstly, let’s look at some points I’ve raised:

  • Incorrect locking for global_query_id (bug #72544)
    Raised on May 5th, 2014 on the internals list. As of today, no action (apart from Dimitri verifying the bug back in May 2014). There continues to be locking that perhaps only works by accident around query IDs.Soon, this bug will be two years old.
  • Endian code based on CPU type rather than endian define (bug …

On Upgrades to Percona Server 5.7 GA: Building from Git Source on Fedora

While writing my first post in this series I was bulding Percona Server 5.7 from Git sources on my wife's Fedora Core 23 box based on this manual page, for my collection of test instances. As I build MySQL and related software from sources on different platforms almost every day for 11 years already, the process was completed successfully without much troubles, but there are still some details I'd like to highlight.

Manual says one has to do the following:

$ git clone https://github.com/percona/percona-server.git
$ …

On Upgrades to Percona Server 5.7 GA: CentOS 6 Case

As you probably noted, Percona had finally released Percona Server 5.7 GA two days ago. I had not paid much attention to this branch during last month or so, but as it's GA now I decided to check what's there, how it works and install/upgrade different boxes and VMs to use it.

For testing purposes and for this series of blog posts I am going to build it from Git source (at least on Fedora Core 23), upgrade to it on 32-bit Ubuntu 15.04 VM, upgrade to it on 64-bit Ubuntu 14.04 laptop, upgrade to it on 64-bit CentOS 6.7 VM and maybe more. If any of the attempts to install/upgrade ends up with something worth sharing, I am going to write about the experience, problems (if any) and solutions.

Yesterday I've spent some …

MySQL Support People - Percona Support

I planned to continue this series of posts with the one about MySQL Support engineers who joined us in Oracle while I was working there, but based on recent events in my life I'd prefer to postpone it and move directly to the team I worked for during last 3+ years, Percona Support Team.

Disclamer: In the list below I still try to pay attention to public contribution by each of engineers mentioned to MySQL Community, mostly in a form of bug reports. This is not the only way they contributed, but I have to stick to this format in current series of posts. I also base my comments mostly on my memory and quick search of public sources of information, so I may be mistaking about the roles, time periods and other details. Please, inform me if you think there is something to fix.

So, here is the list of my former colleagues who formed the best MySQL Support team in the industry in 2013-2015 while working with me in …
