Development

Thinking about moving on to Servlet 3.0

One of the current efforts under way in the dev list is driven by Tom Fennelly et al, who is working on introducing a series of small ball improvements to the user interface in Jenkins. If this is something you are interested in (and who aren't?), you should see Kevin Burke's manifest that sets out the plan of attack, and This mega thread on the dev list for the discussion.

There are numerous sub-conversations born out of this, and one of them is the minimum required servlet spec version for Jenkins.

Jenkins devs are thinking about ways to update page contents post load, for example so that the list view will keep updating as stuff happens. WebSocket was discussed as an option, and then server-side events, which seems to be the current favorite.

Acceptance test project progress report

Over the past 30 days or so, the acceptance test project has made a great progress.

This project consists of a reusable harness that can be used by plugin developers and users to write functional test cases. These tests can be run against Jenkins instances that are deployed in all sorts of different ways, and can interact with complex real fixtures. These tests can be also run with specific version of Jenkins core and a combination of plugins.

The number of tests have steadily increased to above 300. Several of those are by Michael Prankl, where he tests the LDAP plugin with the real OpenLDAP server instance that runs inside Docker — a kind of test that just wasn't possible before can be now easily written.

Jenkins Office Hour: Tutorial on writing an acceptance test

This week I'm going to do an office hour on how to write an acceptance test in Jenkins acceptance test harness. The event is on Wednesday 11am PT.

This new Selenium-based test harness is full of page objects and other abstractions that let you write blackbox integration tests on Jenkins and its plugins, as well as how they behave under various environments.

Unlike our regular office hours, the event is done through Hangout on air. But I do want at least several people to join Hangout interactively, not just watch the event in a read-only mode.

To join the event interactively (as opposed to read-only), I think you need to come here (but since Hangout URL can change, please check back on this post right before the office hour begins, so that I can post an up-to-date URL.)

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.

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!
