A few weeks ago our very own Kohsuke Kawaguchi gave a presentation at the Silicon Valley CI Summit held in Mountain View.
Within the presentation, Kohsuke included a collection of numbers about the vibrancy of the Jenkins project that certainly hasn't gotten enough attention. While the slideshow is embedded below, here's some good high-level points:
- Over 170 GitHub pull requests in the past four months, with more being sent every day.
- Formalization of a "Jenkins Stable" branch of development with longer release cycles and back-ported bugfixes.
- Over 280 tickets in JIRA have been resolved.
- After posting a "special" release of Hudson which presents users with a choice, 87.25% are choosing to upgrade to Jenkins.
- Over 500 tickets have been created
- Roughly 13,000 downloads of
jenkins.war and native packages a week
- New and vibrant community-driven initiatives like Frederic Camblor's plugin compatibility tester and Charles Lowell's JRuby plugin support project.
- We've crossed 1500 participants on the
jenkinsci-user mailing list, and are over 900 participants on the
- The @jenkinsci twitter account recently crossed the 4,000 follower threshold.
On a personal note, I think this speaks all to the level of unbridled enthusiasm about the future of Jenkins by contributors both new and old.
Without further delay, the slides:
Thanks to the kindness of BigPoint GmbH and Kutzi, we had the first Jenkins Hackathon in Europe, in a very large and airly conference room in their Hamburg campus, on a nice sunny Sunday of May 1st. About 10 people came, including the static code analysis plugin fame Ullrich Hafner, Androd emulator plugin fame Christopher Orr, the instant messenger plugin (and others) fame Christoph Kutzinski. Some of us came from pretty far away places like Munich, Bonn, and Netherland. There was a good mix of existing developers and new developers, too.
Jenkins is now at 1.400 (as of last Monday, yes, I know. But better late than never...). As with 1.300 and 1.200, this release doesn't particularly signify any substantial major release, but nonetheless it is a milestone for those of us who are involved in the project — I think repeating something 400 times is something one can be proud of. It's a bit like climbing a mountain. Left foot, right foot, left foot, right foot, ... and when you look up, voila!
Updated usage statistics are now available at http://jenkins-ci.org/census This data has been scrubbed of distinguishing information as much as possible, filtered for installations we've seen at least twice a month with at least one job set up, and split up into monthly JSON files. Starting with August, we only have data on installations of version 1.368 or later - before that, reports go to the old Oracle-owned server, and we aren't able to retrieve them. So that's why you'll see a fairly hefty drop in install count, etc from July to August.
I haven't had a chance to do any analysis to speak of on the data. I intend to get the plugin usage spreadsheet updated n the next few days, but I wanted to make this data available to you all ASAP. If you come up with any interesting analysis or use of the data, please let us know!
