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:

Jenkins Bazaar plugin 1.19
+0 Vote Up -0Vote Down

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.

New Jenkins Bazaar plugin release! 1.18
+1 Vote Up -0Vote Down

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.

Hacking the Jenkins BZR plugin
+2 Vote Up -0Vote Down

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

OpenStack's Jenkins Job Filler
+1 Vote Up -1Vote Down
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

New Gerrit and Jenkins styles are live
+1 Vote Up -0Vote Down
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,

07.12. One-click Deployment
+0 Vote Up -0Vote Down

Today's topic is deployment. It's called one-click deployment for a reason: Developers are lazy.
It's hard to do less than clicking on one button, so that's our goal.

With the growing need for lower time-to-market and faster response to user feedback it is inevitable to not be limited by technical factors (there are enough other obstacles already). The focus lies on reproducible results.

So, what do we need? Actually, not much. Disregarding the tools and practices that build the foundation of agile software development, you only need a central build server. But you've already got that one covered, right?

If you don't, you should get one. It's a huge help to discover errors quickly and be alerted instantly. This usually leads to a shorter time frame until a fix is done. Tests are run continuously and new parts are

Using Jenkins to parse sphinx warnings
+1 Vote Up -0Vote Down

At Percona, we’re now using sphinx for our documentation. We’re also using Jenkins for our  continuous integration. We have compiler warnings from GCC being parsed by Jenkins using the built in filters, but there isn’t one for the sphinx warnings.

Luckily, in the configuration page for Jenkins, the Warnings plugin allows you to specify your own filters. I’ve added the following filter to process warnings from sphinx:

Why Oracle’s donation of OpenOffice disappoints
+2 Vote Up -2Vote Down

While Oracle deserves some praise for its donation of OpenOffice.org code to the Apache Foundation, it is disappointing again to see a legitimate open source market contender that has been marginalized by miscommunication and mismanagement of the project by a large vendor.

OpenOffice.org, warts and all, was probably the most significant competition for Microsoft Office for years and in many ways demonstrated the advantages of open source, helping usher in wider use of it, as well as greater usability. OO.o was in fact my reason for originally investigating and moving to open source software more than a decade ago. Regardless of past mismanagement of community and technology, that competitive factor has been diminished greatly since Oracle took ownership of
