Active Directory plugin improvements



One of the few plugins that I still personally maintain is Active Directory plugin. In the past few months, I've been making steady improvements in this plugin, thanks to various inputs and bug reports given to me from the ClodBees customers.

One of the recent fixes was to get the "remember me" feature finally working for Active Directory. This requires a relatively new Jenkins 1.556, but it eliminates the need to having to constantly type the password in.

Then I've rebumped the version of COM4J, which was causing a thread leak when Jenkins runs on Windows. If you are running a Windows deployment with lots of active users, this probably would have contributed to the instability of Jenkins.

Upcoming Jenkins Office Hours: Acceptance Test Harness

One of the new efforts in Jenkins this year is the acceptance test harness for Jenkins.

We will be doing the Jenkins office hours next week to go over this and sync up and coordinate between people in the community that are trying to work on this.

It'll be April 23rd 11am PT (see what this time is in your time zone) on Google Hangout at http://jenkins-ci.org/hangout. If you are intereste in hacking Jenkins or if you are a large user of Jenkins who have acceptance tests, we are looking forward to seeing you there.

For those of you who haven't looked, this test harness allows you to write blackbox tests of Jenkins and its plugins. It was originally used to test LTS releases, but over the time, it acquired a number of features, such as ...:

  • Docker support for launching complex fixtures to test Jenkins with.
  • Pluggability to launch Jenkins under test (JUT) in many different environments

Jenkins 1.532.3 LTS is released

The final LTS release of the 1.532.x line is out today. You can download it from the usual location. Changelog is here.

Starting with the next 1.554.x LTS, the release model will switch to the train model, where we commit to dates and get whatever we can ship by that date.

You can see the scheduled dates in our event calendar. Backporting window for 1.554.1 is almost closing, so if you want to have your favorite issues nominated for it, please see the process in the Wiki and hurry!

InfoQ CI survey 2014

InfoQ has been running a CI server survey for more than a month now, and here is the current result:



Jenkins has gotten more than 70% of the votes, once again proving the wide adoption among developers. If you are one of those who picked Cruise Control into the "considering" section, I'd encourage you to look around a bit more.

You can still vote from their website or leave comments if you want.

By the way, the design of two axes make no sense to me; for example, I'd order the adoption axis to "considering -> migrating to -> using now -> moving away from", and the circle seems to imply two axes are somehow interchangeable, when it should probably be just in a checkerboard to indicate those are independent axes.

More scalable slaves



Nio

NIO-based Java Web Start (JNLP) slave handling is coming to 1.560. This will help you run a large number of JNLP slaves more efficiently. A connected JNLP slave used to occupy one thread on the master, but now it occupies none. Combined with the earlier change that eliminated threads from idle executors, now you can connect thousands of slaves.

All you have to do is to use the latest slave.jar from Jenkins 1.560. No other changes are necessary on users' part.

A bulk of this is implemented in remoting 2.38, and a good part of it was implemented about a year ago on the airplane on the way to Europe.
