I have released MySQL-Sandbox 3.1.01, which is the first release after the move to GitHub. While the changes are not so spectacular (it's a minor release, with mostly bug fixes), I am pleased to see that the move has started producing collaboration. Two of the changes were provided by Daniël van Eeden and Mark Leith, who have scratched some of their own itches by providing useful patches.

All in all, this period of working with GitHub has been liberating. Although Bazaar plays with the same principles of git, it lacks most of the tools and the know-how which characterizes git. Add to this that also my team has moved Tungsten Replicator …

Welcome to MySQL QA Episode 2: Build a MySQL Server – Git, Bazaar (bzr), Compiling, and Build Tools

In this episode you’ll learn how to build Percona Server and/or MySQL Server for QA purposes & more in this short 25 minute tutorial.

Today marks a milestone in terms of the MariaDB project – going forward, the MariaDB project plans to use Github and git for source code management. The migration happens from Launchpad and the bzr tool.

The 10.1 server development (under heavy development now) will happen on Github. You can check it out here: https://github.com/MariaDB/server. Feel free to watch, star or even fork the code, and send us contributions!

Previous maria-captains should now provide their Github IDs so that they can be accorded similar status. Send the IDs to the maria-developers mailing list.

The project eventually wants to move the 10.0, 5.5, 5.3, …

I recently released a new version of the Bazaar plugin for Jenkins. This release was inspired by a problem we noticed at Percona. It is:

• run “bzr revert” after a pull, as if you have a directory that is removed and re-added while having unknown files in said directory (e.g. build artifacts), you would end up in a very bad place (this is a BZR bug, so we work-around it with a “bzr revert”).

The update has already appeared in the Jenkins update centre, so you should already be able to upgrade to it.

From the desk of your new Bazaar plugin for Jenkins maintainer, I give you Version 1.18.

This release has two good bug fixes:

• UI fix for checkout option (JENKINS-12261)
• Auto-recover from corrupt BZR branches (e.g. bzr branch/checkout killed at inopportune moment) by cleaning the workspace and trying again (this is now default behaviour, best used with the Jenkins SCM retry count feature being > 1)

We’ve been running the same code as this release at Percona for about 2 months now (the second bugfix was one I wanted to test first before submitting upstream). This is the big fix that fixed all our problems with using bazaar with Jenkins in a large deployment.

The other news? I’m now maintainer, and this is my first release.

For Drizzle and for all of the projects we work on at Percona we use the Bazaar revision control system (largely because it’s what we were using at MySQL and it’s what MySQL still uses). We also use Jenkins.

We have a lot of jobs in our Jenkins. A lot. We build upstream MySQL 5.1, 5.5 and 5.6, Percona Server 5.1, Percona Server 5.5, XtraBackup 1.6, 2.0 and 2.1. For each of these we also have the normal trunk builds as well as parameterised ones that allow a developer to test out a tree before they ask for it to be merged. We also have each of these products across seven operating systems and for each of those both x86 32bit and 64bit. If we weren’t already in the hundreds of jobs, we certainly are once you multiply out between release and debug and XtraBackup being across so many MySQL and Percona …

Not counting obtaining the source code, and once you have the prerequisites satisfied, [Windows] users can build from source code in 5 easy steps.

Prerequisites – Install & ensure they are in the $PATH:

1. CMake <-- Download
2. C++ compiler <-- Visual Studio 2008 Express - Free Download
3. Bison <-- Download (ensure m4.exe is also included, which it should be)

Optional (but most likely you’ll want):

1. Perl <-- For Test Suite/Scripts. Strawberry Perl is a great option.
2. Bazaar <-- If want latest …

Mark Callaghan asks Can a protocol be GPL?, after finding a disturbing comment in a source file: Any re-implementations of this protocol must also be under GPL, unless one has got an license from MySQL AB stating otherwise.
I recall talking with one of the company lawyers about this matter, and he assured me that the GPL can't be used for a protocol, and that's why this notice was dropped from MySQL.com site a few years ago, even before the Sun acquisition.
This is thus an embarrassing piece of ancient history (which will hopefully be removed soon) that has been in our files for long time. For how long?
If we get the source trees from the public bazaar …

Why a New Utility?

A couple of months back, Tim Procter, Sheeri Cabral and I were discussing about how best to diagnose a MySQL server and/or tune its performance, automating the process as much as possible. The Performance Advisors from MySQL Enterprise do this, but most of our customers don’t have a subscription and Pythian’s collective experience is not necessary reflected by its rules.

In our daily work, we have used Major Heyden’s MySQL Tuner, Mark Leith’s Statpack and our own tools to review a MySQL server configuration parameters. However, all of these tools had limitations in regards of what we wanted to achieve. Our major …
