I spoke last month at linux.conf.au 2014 in Perth, Australia, and one of my sessions focused on the “Continuous Integration (CI) testing of Percona XtraDB Cluster (PXC)” at the Developer,Testing, Release and CI miniconf.

Here is the video of the presentation:

Here is the presentation itself:

Percona XtraDB Cluster before every release: Glimpse into CI testing from Raghavendra PrabhuBelow is a rough transcript of the talk:

This talk covered the continuous integration testing of the Galera cluster; specifically, Percona XtraDB Cluster (PXC), based on Galera, is taken into …

Today we’re celebrating Percona’s 7th anniversary.  A lot has changed in these past 7 years – we have grown from a two-person outfit focused exclusively on consulting to a 100-person company with teammates in 22 different countries and 18 different states, now providing Support, Consulting, RemoteDBA, Server Development and Training services.

We also made our mark in open source software development, creating some of the most popular …

A couple of us have been taking about it a lot already .. we wanted to host a one day #devops event in .be already last year.. then talks about starting a meetup group started again with @wonko_be but it was @fs111 pushing the final button and calling the rest of the .be community to order, we've set a date
and the first session will take place (agenda still needs to be detirmined)

So all you Belgian devops enthousiasts, maark October 11th in your calendar and go register here

We already have 2 other venues (Gent, Boom) lined up .. but let's get this first one started :)

Next to that here's an update for the rest of my upcoming Conference Season :

• Later this month I`ll be heading to San Francisco for a talk at PuppetConf 2012. I'll probably be around in the valley a bit …

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 …

OpenStack comprises of many projects, all of which have code reviews via. Gerrit and every code review is tested with many tests on Jenkins.  Whilst this is excellent for code quality this can get quite insane to manage.  In fact at time of writing OpenStack's Jenkins server now has a shade under 300 jobs to manage, I don't know about you but I really don't want to be spending my days managing all of that.  Often we need to make a small change to many jobs at the same time and human error occurs.  In the last few weeks we developed and unveiled the CI team's solution to this: Jenkins Job Filler (aka. Jenkins Job Builder when I forget what we called it).

The initial version of Jenkins Job Filler was written in a combination of Ruby and Puppet scripts but unfortunately it became unmanageable very quickly, it also required a Jenkins restart on every change.  So the new version has been writing in Python and YAML. …

After a bit of tweaking and improvements following feedback from various people the new changes to Jenkins and Gerrit are now live. The changes will also be rolled out onto Stackforge in the next 24 hours.

I've had a lot of great feedback in the few hours the changes have been live, many love it and some have suggestions for improvements. This is great, we know the look could use a bit of refining here and there. What makes this truly awesome is that the styles are kept in an OpenStack project with which anyone can file bugs or send patches up to Gerrit.

To modify the styles simply grab the openstack-ci-puppet repo and look in the Gerrit and Jenkins modules for the files. If you wish to file a bug, please do so in the …
