A Busy Weekend

by Alex Handy 01/31/2011 03:05 PM EST

My goodness, a lot happened this weekend, didn't it? I mean, outside of Egypt, Tunisia, Sudan, Yemen, Jordan... Did I miss any countries in there?

Perhaps the biggest for you, dear readers, is this blog posting from Mark Reinhold. In it, he states that himself, John Duimovich and Jason Gartner of IBM, Mike Milinkovich of Eclipse, professor Doug Lea of SUNY Oswego, and Adam Messinger of Oracle are drafting a new take on OpenJDK governance. The initial governance board--while made up of some rather esteemed and intelligent folks--hasn't exactly been active. Reinhold insinuates in his blog posting that the initial OpenJDK governance board has completed its tenure, as he thanks them for their service.

This first draft of new governance rules should be available soon, wrote Reinhold. While governance on the OpenJDK is good news, two very bad things happened this weekend, as well.

By now, you've already heard about Intel. This historically reliable company is just about as predictable as the phases of the moon: it hits or exceeds both product shipment deadlines and earnings predictions every quarter. But the Sandy Bridge processor is a complex beast, and along the way, an engineer or two made a mistake. It sounds like this will delay Sandy Bridge for a month or so. Everyone building with Sandy Bridge will likely have to spend some time reworking schedules, if they haven't already.

Another bit of bad news comes from SourceForge, which was hit by hackers. The consequences are a recommended password reset for all users, the possible removal of CVS services from the site, and a massive write-up describing the entire incident. Everyone needs to check in on their projects ASAP, if for no other reason than to change your password.

Finally, the biggest news of all, for any of you doing Web development in JavaScript: JQuery 1.5 is out. Everyone should check out the changes written up in the blog entry to see what's new, or just download the actual code and dive right in.

WANdisco does the hustle

by Alex Handy 01/05/2011 03:59 PM EST

Just before Christmas, David Richards, CEO of WANdisco, posted an incendiary little blog that all but accused the Apache Foundation of mishandling Subversion. In this blog, Richards wrote that he and his company were unsatisfied with the velocity of Subversion within the Apache Foundation, and erroneously took credit for creating the CMS. Essentially, Richards was complaining about the lack of work on merging and branching within Subversion. From his blog, in response to the question "hasn't Apache laid out a roadmap?":

Yes they did, but that’s pretty much all that happened (and that really pisses us off.) The commit logs (code committed by developers to the project) tell the real story. We are not happy with the volume, speed or participation on the project right now. Blogging, or answering questions on user lists are important, but so is writing source code. We also believe it’s unhelpful when certain unscrupulous committers decide to commit trivial changes in large files to simply get their stats up. That behavior has no place in any open source project; it’s a bad form and wastes everyone’s valuable time. The requirements that we are committing to build, namely merging and branching, are not new. Many of these have been in the mainstream and documented since 2007. I find it more than a little annoying that, given their importance to many Subversion users; these areas have not been tackled. Yes, they are difficult. Yes, they will take time. That is why a corporation needs to step up to the plate and commit to deliver.

Obviously, this ruffed some feathers, as did Richards' use of the word "fork," though he used it to say that WANdisco was NOT forking Subversion. But still, that's not a word you bandy around lightly, even when saying you won't fork. Instead, Richards seemed to take on the role of shepherd for the Subversion project, something his team was unable to do when the project was run exclusively by Collabnet. Still, WANdisco isn't exactly a one-company steering committee for the world's most popular source code management platform. And the Apache Foundation was quick to point this out in their own rebuttal, posted earlier this week. From the <a href="https://blogs.apache.org/foundation/entry/apache_subversion_to_wandisco_1">Apache blog</a>:

The Subversion development team is already working towards the enhancements that WANdisco inexplicably portrays ([2], [3]) as bold, controversial steps that must be pushed through in the face of (conveniently unnamed) opposition. WANdisco participates in Subversion development along with many parties, and the Subversion project has always welcomed WANdisco's contributions. However, WANdisco alleges that some entities want to impede technical enhancements; at the same time, WANdisco also implies that it is the corporate leader of the project.

Neither is true. Since WANdisco does not cite any sources for their specific claims, we cannot explain them. However, a bedrock condition of participation in Apache Subversion is that an individual contributor can have discussions, submit patches, review patches, and so forth, but that companies do not have a formal role. Instead, companies get involved by funding individuals to work on the project. WANdisco's false implication that it is in some kind of steering position in Subversion development discredits the efforts of other contributors and companies.

It should be noted that Richards has now apologized. Everyone can now go back to dancing.

Too big to merge?

by Alex Handy 04/26/2010 02:20 PM EST

A pseudo-meme I've noticed recently has been the discussion of Git and Subversion and their issues when it comes to large projects. It would seem that a repository of 6 GBs or more is too much for the scions of open source SCM. Steve Hanov has a detailed discussion of the problem on his blog. In almost all of the discussions I have seen in the past few weeks, Perforce comes up as the SCM offered as the solution.

There is a head-to-head comparison over on Stack Overflow where some folks compare Perforce and Subversion. It seems the real issue here is simply the way Subversion and Git handle their repositories on disk. When you're dealing with huge trees in Subversion, with thousands of files to move around or merge, it takes a non-trivial amount of time.

Hanov says that Perforce was confronted with this type of problem years ago, by Google. There's a link to a rather large PDF linked to on his blog, but I shan't link to it here due to its size. It's a good read, and gets into some nice juicy details about speeding up access to a large repository.

Google Code turns 5

by Alex Handy 03/17/2010 11:16 AM EST

Yesterday, I ventured down to Google's campus for the celebration of the fifth anniversary of the launching of Google Code. It was a relatively eye-opening experience, as they pointed out a lot of things about their hosting system that I hadn't known previously. For example, while the site launched with four projects and two APIs, it's now hosting over 905 projects and 60 APIs. And that's just Google's stuff. End users have uploaded over 300,000 of their own projects to the site, and 26,000 of those were updated in the last month. 

Java is the most popular language used in Google Code projects, with PHP and Python both close behind. What is interesting here is that C++ and C# are dead even at 4% of the overall  projects. There are over 4000 Android applications in Google Code, and over 1000 Eclipse projects. The band, Radiohead, used the service to host its music so that fans could remix their songs, and the source code to the Apollo 11 guidance computer is hosted there as well.

But those are just numbers. What was really interesting to me was the way the Google folks took credit for simplifying online project hosting. And you know what, they're right: they did push open source hosting sites to simplify by offering a streamlined alternative.

How did Google streamline Google Code? For one thing, issue tracking was refined to the same simple interface you'd get when posting a comment to a Web site. Rather than ask bug submitters to post up huge amounts of information and click tons of radio buttons, as is the case in Bugzilla, the Google Code issue tracker submission window is nothing more than a title bar, and a big blank text box in which to describe the issue. 

Elsewhere, Google made it easy to host your project on their site, and took approval and compliance processes out of the system entirely. Sourceforge notably required a lot of hoop jumping back in 2005, and Google decided to ditch these requirements and just allow anyone to host projects there.

Google also took the controversial tactic of restricting license usage on Google Code. They whittled the choices down to the bare minimum, and as a result, over half of the code hosted there is either GPLv2 or GPLv3. A quarter of the projects are under the Apache License, and the rest are a mix of Eclipse, MIT, and a handful of others. As Google engineer, Ben Collins-Sussman put it, if you can't get what you want out of the licenses they chose, you're doing it wrong. He also said that many developers think of legal documents like code: if they compile, you're good to go. This is super wrong, and can get you in trouble. So Google has used Google Code to halt open source license proliferation and dilution.

For the fifth anniversary, Google implemented a Paxos algorithm in the backend of Google Code, so now updates will be instant and reliably replicated.
