There's been a lot of discussion on the new mailing lists as of late regarding some of the infrastructure and ownership of the Hudson project. In case you haven't been following along at home, I'll try to catch you up as impartially as possible.

The Facts

• 2009.06.02: After substantial problems with Java.net infrastructure, the dev community discusses new infrastructure options, including SourceForge, Google Code, Kenai, Berlios, GitHub, etc. Instead of moving the entire project, some key components such as the issues.hudson-ci.org are moved off of Java.net. Discussions about moving source code off of Java.net and onto other hosts like GitHub come up almost every four months on the mailing lists, typically coinciding with serious Java.net downtime or reliability issues..
• 2010.11.01: A discussion occurs on the developers mailing list about adding Winston Prakash, the Oracle engineer re-assigned to replace Kohsuke Kawaguchi (Hudson founder/lead developer), as a co-owner to the Java.net project. Winston mentions that his question was driven by Oracle management who felt he should "co-own the project." After a round of discussion, it's decided by the devs list that it's acceptable and grants Winston co-ownership of the project as a sign of good faith from the community towards Oracle.
• 2010.11.17: Andrew Bayer, core contributor and maintainer of numerous plugins emails the users and devs list with a proposal to move the mailing lists off of Java.net which has had notorious reliability issues within the Java ecosystem and was scheduled for a series of downtimes and migrations over the coming weeks. Google Groups is selected as the most reasonable by the community.
• 2010.11.19: Hudson project is lumped into the same Java.net migration bucket as Glassfish. Emails are sent to project owners, the users and the developers list. The mail to users and developers never arrives due to the sender not being subscribed. Both project owners (Kohsuke, Winston) miss the message, leaving the Hudson community in the dark regarding the pending migration.
• 2010.11.22: Shortly after midnight, Jacob Robertson reports that his SVN credentials no longer work, Kohsuke informs the developers list that the project is locked due to the migration, SVN is inaccessible and mailing lists fail shortly after that. The Hudson Java.net project begins its migration from the legacy infrastructure to the newer Java.net infrastructure (formerly known as "Kenai"). A group of core Hudson community members accelerate the move to Google Groups, pushing out announcements via this blog and twitter hoping to keep as many members in the loop as possible.
• 2010.11.23: Frustrated by the locking down of Hudson's source code, which sees between 3-8 commits to "core" a day, not counting the 300+ plugins, Kohsuke proposes moving to GitHub on the new developers mailing list. The general consensus amongst the plugin and core developers was to go forward with moving to GitHub, no major objections were raised by the developer community.
• 2010.11.27: After Thanksgiving, Andrew Bayer submits the "formal proposal" for migrating over to GitHub, Sets a deadline of the following tuesday (2010.11.30) for raising any major objections before "flipping the switch."

The Monday morning prior to the planned switchover to GitHub, Oracle Senior VP of Tools and Middleware Ted Farrell sent a message to the users list expressing concerns he had regarding the migration of the Hudson codebase from Java.net to GitHub: > Oracle's goal is to grow the community and make hudson stronger.

(Ted's message was rather long, you can read the whole post here)

As one might expect, Ted's response to the thread was received with mixed responses ranging from general confusion to obvious frustration.

Long time contributor to Hudson's Git plugin, Nigel Magnay tried to clarify the benefits of migrating to GitHub instead of using Git on the "new" Java.net as succinctly as possible:

Just having git support != git support on github. They work full time on providing the best community development tools; I doubt kenai could even catch up, let alone surpass what they're doing.

…

I'm confused.

What things are you saying you will not let the Hudson developer community do?

I.E: Are you saying that, as the holders of the Hudson 'name', you are prohibiting the developer community from choosing (for ourselves) to migrate the infrastructure (bug tracking / wiki)? The repositories ?

So far the response from the developers has been pretty strongly in favour of the migration to google groups for mail, to github for code repositories and collaboration, and to a self-hosted site for bug tracking and information.</em>

Ted's response to Nigel contained one of the most important nugget of information for the whole discussion nestled in the middle of the message:

Nigel, what I am saying is that I believe the final decision of what to do w.r.t. infrastructure belongs to Oracle and that decision should be made according to the will of the community as it makes sense

The part where I editorialize

I readily admit, there is a lot of information to take in here, for clarification there are two distinct "communities" involved in Hudson:

• developers: the hundreds of developers actively communicating on the developers list and contributing to the 300+ plugins
• users: tens of thousands of individuals and companies using Hudson either as a straight .war file, or using the native packages provided by the community

The fundamental issue here is that the developers want to make a change in how they contribute to Hudson, and have made their voices heard to that end. From the users' perspective, such a change would have literally zero impact on them, which makes Oracle's conflation of the two sides of Hudson particularly frustrating.

Part of the impasse between Oracle management and the developer community lies in an inherent meritocracy in any large open source project, whether it be the Linux kernel, the Python language and runtime, or the PostgreSQL database server, those that contribute carry more weight within the community because they are actively pushing things forward. On top of that, Oracle continues to cite a "larger community" that's apparently larger than those active committing to Hudson on a daily or weekly basis, without naming names or citing specific contributions.

Ted, and in turn, Oracle's approach to the Hudson community seems to stem from a systematic misunderstanding of how most (if not all) major open source projects operate. Mentiong closed-door meetings between Sonatype and Oracle regarding "how to make Hudson better" do nothing to aid many developers' concerns about Oracle's commitment to Hudson as an open source project or a community.

In my humble opinion, we are being told one thing while Oracle's actions speak to another. Insisting that Hudson development remain on Java.net, after the development community committed to GitHub, contradicts the words promising to work with the Hudson community and to help facilitate its growth. Asserting that Oracle isn't trying to exert unwelcome control over the project, while doing exactly that.

Personally, I do want Oracle to continue to be involved, along with CloudBees, Sonatype and many other companies that contribute to the ever-growing Hudson ecosystem. The involvement of a plethora of different companies only helps emphasize the importance of Hudson to the developer community and underline the value of Hudson as a community owned and operated project.

December will be an interesting month, stay tuned.
