A year with Drizzle
+1 Vote Up -2Vote Down

Today I'm coming out of the closet. Since I'm a professional database expert I try to be like the mainstream and use the commercial MySQL forks (including MySQL itself). But I think those close to me have already known for some time that I like community based open source projects. I cannot deny it any longer, so let me just say it: I'm a Drizzle contributor and I'm very much engaged!

I've been eyeing the Drizzle project since it started in 2008. Already then there were dozens of MySQL hackers for which this project was a refuge they instantly flocked to. Finally a real open source project based on MySQL code that they could contribute to, and they did. It was like a breath of fresh air in a culture that previously had only accepted one kind of relationships: that between an employer and an employee. Drizzle was more liberal. It accepted also forms of engagement already common in most other

Making rpm builds a first class citizen: How?
+0 Vote Up -1Vote Down

In my previous post I explained why I believe the production of RPM and DEB packages should be more integrated with the rest of your development process. Now it's time to look into how you can put the RPM build scripts inside your main source code repository, and in particular how I did that to produce RPM packages for Drizzle.

Making rpm builds a first class citizen: Why?
+0 Vote Up -2Vote Down

Last weekend I released rpm files for the latest Drizzle Fremont beta (announcement). As part of that work I've also integrated the spec file and other files used by the rpmbuild into the main Drizzle bzr repository (but not yet merged into trunk). In this post I want to explain why I think this is a good thing, and in a follow up post I'll go into what I needed to do to make it work.

(And speaking of stuff you can download, phpMyAdmin 3.5.0-alpha1 now supports Drizzle!)

The easy way to manage virtual/cloud images: from the outside with userdata and runurl scripts
+0 Vote Up -0Vote Down

In March I posted a series of blog posts on my paternity leave MepSQL project, which I called MepSQL. There was still one piece created in the MepSQL buildsystem that I didn't publish or blog about. Since it is generally useful, I wanted to generalize and polish it and publish it separately. I finally had that done last week, when I also found that somebody else, namely alestic.com already published a similar solution 2 years ago. So yesterday I ported my BuildBot setup to use that system instead and am happy to publish it at the Open DB Camp 2011 in Sardinia.

Ok, so let's go back a little... What is the

Footnotes for Drupal 7 released, announcing handover to new maintainer
+1 Vote Up -1Vote Down

I finally did the migration to Drupal 7 for the Footnotes module this weekend. See Release notes and project page for more information.

With this release I also announced my intent to hand over the module to a new maintainer. Since I'm now increasingly active with affairs in the MySQL community, both hacking as well as other community tasks, it is prudent to not let old projects dangle without attention but to formally hand them over to fresh minds.

Back to work: 1st week as Senior Performance Architect at Nokia
+3 Vote Up -2Vote Down

As some Facebook friends already guessed from my status updates this week, my 9 month paternity leave is now over and I've survived my first week back in work life, waking up at seven in the morning! This is just a personal-life blog post to let everyone know what I'm up to, (For those asking: Ebba is doing fine, she recently started to stand up and even takes steps if I hold her hands.)

During the past months I had many interesting conversations and ideas of what to do next, but in the end Nokia was the company standing out with a very interesting offer. So as of last Tuesday I work at Nokia as Senior Performance Architect in the Mobile Solutions division, better known as the Nokia Ovi web services.

Overview and archeological exploration of the MepSQL Bakery
+1 Vote Up -2Vote Down

This is the final part in a series of posts about the MepSQL build system known as MepSQL Bakery. MepSQL is a (yet another) fork of the MySQL database server, with the server based on the MySQLatFacebook code and the build system based on the MariaDB build system.

In this final post I wish to draw a high level picture of the complete process of building TAR, DEB and (eventually) RPM packages from the source code. There's not much more technical details to add to the previous posts, instead I'm going to make some, shall we say "archeological", observations which imho are interesting given how the build system has evolved when being passed from one project to another. Perhaps

Dealing with the Cambrian Explosion 2/2: Parameterizing the package name in DEB files
+1 Vote Up -1Vote Down

Yesterday I wrote down the approach used in the MepSQL build system to parameterize the TAR package name produced. Today I will follow up with how the same was done for building DEBs. The motivation is to create a system that can be used flexibly to create packages of any MySQL fork, with any brand name: mepsql-server-*.deb, percona-server-server-*.deb, mariadb-server-*.deb or even just mysql-server-*.deb (which I might do some day).

While yesterday's tricks with the TAR files were rather straightforward, with the process of building DEBs this turns out to be much more challenging. But not to worry, like

Dealing with the Cambrian Explosion 1/2: How to parameterize the package name in source and binary TAR files
+1 Vote Up -1Vote Down

As I mentioned before, it seems that thanks to Git and Bzr introducing distributed version control workflows, the open source community is now living in a phase where forking is easy and happens frequently - referred to by Brian Aker as the Cambrian Explosion of open source. We certainly see that happening in the MySQL Community.

Assuming you have the competence and know your way around a codebase, forking a proper open source project isn't that hard. You create your own project on GitHub or Launchpad and copy the source code.

Going from MariaDB to MepSQL BuildBot setup and using EC2LatentBuildSlave to save money
+1 Vote Up -1Vote Down

This is the third post in a series about developing the MepSQL build system. In the previous posts we chose BuildBot running in the Amazon EC2 cloud. In this post we actually get a closer look at how the packages are being built (to be followed by even closer looks in later posts :-)

One of the things missing when you fork MySQL is the build system. (The other main missing component being the manual.) It is possible for anyone to compile MySQL from source, but the actual build system (scripts, testing, etc) used by MySQL itself is not public. The same is true for the automated testing. MariaDB uses the open source

Why to choose a cloud service, and which one
+1 Vote Up -0Vote Down

This is the second part in a series of posts about how the MepSQL packages were built. In part 1 I evaluated OpenSuse Build System and Launchpad PPA and ended up concluding that running your own BuildBot system is the best choice, as those public services didn't provide any facility to test their packages.

This brings us to the next topic: As I don't possess any servers, should I buy one (or more) or should I try out the cloud services? If yes, should I use Amazon EC2 or something else?

Looking at OpenSuse Build Service and Launchpad PPA (aka: How to build packages for MepSQL?)
+1 Vote Up -1Vote Down

This is the first part of many posts in a series of blog posts where I want to document how the MepSQL packages were built. By doing that, I will also end up covering the MariaDB build system (which this is based on), some of BuildBot, Amazon EC2 cloud and packaging DEBs and RPMs just in general, so it could be interesting from many perspectives. In this first part I'll simply scribble some notes about reviewing the OpenSuse Build System, Launchpad PPA service vs using your own servers and automating the builds with BuildBot.

Originally I just wanted to work on some new ideas on the automated build and QA system used by MariaDB. But since leaving Monty Program I didn't have access to any of those servers anymore, so as a first step I had

MepSQL Debs for Ubuntu now released - courtesy of cool tweaks to the build system.
+1 Vote Up -0Vote Down

After another week of hacking on MepSQL the DEB files for Ubuntu are now available.(MepSQL is my new "just a hobby" MySQL fork project.)

The Download page has instructions on how to install the packages with a simple apt-get install command. Debian packages will appear soon as they are now easy to add - I mostly just need to add new Amazon images for each.

Announcing MepSQL, continuing the "Cambrian Explosion" of MySQL forks
+3 Vote Up -12Vote Down

Some time ago Stephen O'Grady and Brian Aker had an interesting Blogo-dialogue about what they call the "Cambrian Explosion" of open source development. The Cambrian Explosion means that we increasingly see forks of projects being developed in different directions, where traditionally we are used to open source development happening in relatively hierarchical and easy to follow upstream and downstream relationships. This is exactly what happens in the MySQL community currently, where in total there is more progress than ever before, but that progress is divided among several competing forks, none of which is
