Rush delivery from Hudson HQ! Hudson 1.351 just rolled out with a very important regression fix: Regression in 1.350 that can delete old build artifacts. ( mailing list thread, issue 5937) Sorry for the hiccup everybody, we’re working pretty hard on getting a better, more stable, release process in place. You can go grab the latest .war file straight from hudson-ci.org or if you’re using a native package, use your package manager to upgrade.

Finishing off the second week in March, the Hudson team rolled Hudson 1.350 off the assembly line last Friday, bringing a slew of fixes. Of particular interest to users of Hudson’s various native packages for Red Hat, openSuSE, Ubuntu/Debian and Solaris, was a change that suppress the "self-upgrade" functionality in the "Manage Hudson" page. On the enhancements side of the fence, the team added authentication support to the Hudson CLI ( issue 3796) allowing Hudson users with locked down installations to take advantage of everything the CLI has to offer. Internal to Hudson, some more changes from Alan Harder (a.k.a mindless, a.k.a The Garbage Man), deprecating or otherwise removing deprecated APIs. Alan’s been doing some great work on Hudson’s internals, if you’re coming out to this weekend’s hackathon, but sure to pat him on the back for his tireless efforts. Bug fixes Fix handling of relative paths in alternate settings.xml path for Maven projects. ( issue 4693) Alternate settings, private repository, profiles, etc were not used in embedded Maven for deploy publisher. ( issue 4939) Make editableComboBox work in repeatable content, such as a build step. If content is captured using ..content.. , fixed this to use proper HTML rendering when appropriate. '<' and '&' in the console output was not escaped since 1.349 ( issue 5852) Fixed an AbstractMethodError in SCM polling under some circumstances. ( issue 5756) Fixed a ClassCastException in the Subversion plugin - now using Subversion plugin 1.13. ( issue 5827) The Maven Integration plugin link in the Update Center was going to a dead location. ( issue 4811) On RPM/DEB/etc installation, don’t offer the self upgrade. It should be done by the native package manager. ( report) Fixed a possible lock up of agents. Enhancements Added advanced option to LogRotator to allow for removing artifacts from old builds without removing the logs, history, etc. ( issue 834) Authentication support in Hudson CLI. ( issue 3796) Added console annotation support to SCM polling logs.

Apologies for the slight delay in posting another TWiP, both within the Hudson community and outside of it, it was quite a busy week. This past week we’ve had roughly 15 plugins released, with a few going through a number of iterations over the course of the week such as the Emma plugin and one of Hudson’s newest plugins, the Libvirt Slaves plugin. One of Hudson’s most active contributors, Alan Harder (a.k.a mindless) was responsible for this week’s only new plugin: Copy Artifact Plugin. The Copy Artifact plugin does exactly what you’d think it does, according to the short-and-sweet wiki page: Adds a build step to copy artifacts from another project. If you’re a plugin developer in the Bay Area, this upcoming Friday and Saturday is the Bay Area Hudson Hackathon/Meetup; don’t miss out! Mar 07, 2010 Copy Artifact Plugin 1.0 Emma plugin 1.15 Mar 08, 2010 CAS protocol version 1 plugin 1.0.1 Copy To Slave Plugin 1.2 Emma plugin 1.16 Libvirt Slaves plugin 1.1 Sidebar Link 1.4 Subversion Plug-in 1.13 Mar 09, 2010 Emma plugin 1.17 Mercurial plugin 1.26 Mar 10, 2010 Libvirt Slaves plugin 1.2 Mar 11, 2010 File System SCM 1.7 Mar 12, 2010 Perforce Plugin 1.0.24 Mar 13, 2010 IRC Plugin 2.2 Jabber notifier plugin 1.6 Sonar Plugin 1.4 global-build-stats plugin 0.1-alpha4 instant-messaging plugin 1.5

Ever wanted to pick the brains of multiple Hudson developers and users, all at the same time? Feel like finally meeting Kohsuke in person? Now’s your chance! We’re hosting our second-ever Bay Area Hudson Hackathon/Meetup on March 19th and 20th. That’s nearly two whole days of Hudson! Day One (Mar. 19) The first day of the hackathon/meetup is aimed primarily at those working with Hudson’s core, or are building on top of Hudson (plugins, etc). Start: 10 a.m. End: 5 p.m. Location: Oracle Santa Clara campus in the "library" conference room of SCA7 "Mansion" building. There will a number of community and corporate Hudson hackers joining us on Friday, so bring everything you’ll need to get some grade A hacking done with Kohsuke, Andrew Bayer, Alan Harder and your fellow plugin hackers. Day Two (Mar. 20) I’m tentatively calling this the main event, which will be hosted at the delightful Hacker Dojo in Mountain View. The "main event" will carry over the hackathon from the day before at Oracle, into a full blown community hackathon and meet-up. This is for Hudson hackers and users alike! Start: 10 a.m. End: 6 p.m. Location: Hacker Dojo (Savanna room) As I’ve pointed out before, Hudson’s getting a lot of attention in other developer circles such as the Python, Ruby, Cocoa communities. As such, I’m hoping to get a lot of folks interested in using Hudson to come to Hacker Dojo where we (already being Hudson users) can help get them up to speed with all the great things Hudson can do. If you’re interested please RSVP: Via the hackathon page on the wiki Via Facebook for day one and day two How you can help While I casually refer to myself as a "PR intern" for Kohsuke, I’m technically a busy software engineer, meaning I’m grateful for all the help I can get. Get the word out The best way to help get the word out is to talk about Hudson and the meetup, this includes: Link to this post on Twitter Ping any user groups you are a member of in the area Blog about it Let your co-workers know about it Attend! Volunteer to help setup/teardown Hosting the Saturday event at Hacker Dojo does carry some responsibilities with it. We will need some extra hands to make sure everybody has power, refreshments are chilled, lunch is ordered and delivered, and of course, cleaning up after we leave. If you’re in a generous mood, or in a real need for some karma, sign up to help on the bottom of the wiki page I am hoping Oracle and some other heavy users/contributors will kick in a few bucks for lunch and drinks on Saturday, if you think your company can help us out, feel free to ping me directly at tyler at linux.com.

Last Friday, March 5th, Hudson 1.349 was pushed out into the wild with an even split of bug fixes and enhancements. Included in this release is Alan Harder’s (a.k.a mindless) old data monitor code, discussed previously in the post " Call for Testers: The older the better." Included in this release were further updates to the japanese and german localizations of Hudson; if you’re interested in helping localize Hudson into more languages you can join the effort via the Internationalization page on the wiki. Now for the breakdown of the 1.349 release: Bug fixes Fix deserialization problem with fields containing double underscore. ( issue 5768) Fix deserialization problem for Exception objects where the XML has bad/old data. ( issue 5769) Fix serialization problem with empty CopyOnWriteMap.Tree. ( issue 5776) Fixed a bug that can cause 404 in the form validation check. Enhancements Remote build result submission shouldn’t hang forever even if Hudson goes down. Added a monitor for old or unreadable data in XML files and a manage screen to assist in updating files to the current data format and/or removing unreadable data from plugins that are no longer active. "Manage Hudson" page will show a link if any old/unreadable data was detected. Added a mechanism to bundle init.groovy inside the war for OEM. ( report) Added an extension point to annotate console output. ( issue 2137) Contributors Hudson 1.349 contains 43 commits from 6 contributors, due to the merging in of Alan Harder’s old-data-monitor branch the commit count is a bit off from the amount of code change that actually went out in 1.349. abayer kohsuke mindless sogabe swiest wyukawa As usual, you can go grab the latest .war file straight from hudson-ci.org or if you’re using a native package, use your package manager to upgrade.

For those of you living in or around Silicon Valley, next Wednesday (March 10th) you might want to reserve some space around 6pm on your calendar. Frederic Simon and Yoav Landman from JFrog will be presenting at the Silicon Valley JavaFX Users Group meeting at the Googleplex. Frederic and Yoav will be discussing and demonstrating how JFrog’s Artifactory works with Hudson to combine continuous integration with release management. Join with the Artifactory team to realize the benefits of managing your software development life-cycle through continuous integration. Frederic Simon (JFrog Chief Architect) and Yoav Landman (JFrog CTO) will demonstrate how to automate large-scale multi-module projects, using a fully-integrated platform with Artifactory and Hudson. Using Maven, Gradle or Ivy builds, it is now possible to dynamically automate and manage the pyramidal stacks of Unit, Functional, and Integration Tests. This demo-based session will show you how Artifactory and Hudson together make it much easier to promote certified builds to milestone releases , and finally to general availability, while making sure all builds are fully reproducible. Staying dynamic all through the development process avoids code freeze and provides very accurate feedback loops. This is crucial for Developers, QA teams, System and Integration testers, Users, Customers, and all the remaining actors of the development process. If you’re interested in attending, you can RSVP on the meetup page
