The state of distributed bug trackers

A whopping 5 years ago, LWN ran a story about distributed bug trackers. This was during the early waves of distributed version control adoption, and so everybody was looking for other things that could benefit from decentralization.

TL;DR: Not much has changed since.

The potential benefits of a distributed bug tracker are similar to those of a distributed version control system: ability to fork any arbitrary project, easier collaboration between related projects and offline access to full project data.

The article discussed a number of systems, including Bugs Everywhere, ScmBug, DisTract, DITrack, ticgit and ditz. The conclusion of our favorite grumpy editor at the time was that all of the available distributed bug trackers were still in their infancy.

All of these piggyback on a version control system somehow - either by reusing the VCS database, by storing their data along with the source code in the tree, or by adding custom hooks that communicate with a central server.

Only ScmBug had been somewhat widely deployed at the time, but its homepage gives me a blank page now. Of the trackers reviewed by LWN, Bugs Everywhere is the only one that is still around and somewhat active today.

In the years since the article, a handful of new trackers have come along. Two new version control systems - Veracity and Fossil - come with the kitchen sink included and so feature a built-in bug tracker and wiki.

There is an extension for Mercurial called Artemis that stores issues in an .issues directory that is colocated with the Mercurial repository.

The other new tracker that I could find (though it has also not changed since 2009) is SD. It uses its own distributed database technology for storing bug data - called Prophet, and doesn't rely on a VCS. One of the nice features is that it supports importing bugs from foreign trackers.

Some of these provide the benefits you would expect of a distributed bug tracker. Unfortunately, all those I've looked at fail to even provide the basic functionality I would want in a bug tracker. Moreso than with a version control system, regular users interact with a bug tracker. They report bugs, provide comments and feedback on fixes. All of the systems I tried make these actions a lot harder than with your average bugzilla or mantis instance - they provide a limited web UI or no web interface at all.

Update: LWN later also published articles on SD and on Fossil. Other interesting links are Eric Sink's article on distributed bug tracking (Erik works at Sourcegear who develop Veracity) and the dist-bugs mailing list.

SambaXP and other travel

It's been a busy two weeks. Wilco and I drove up to Göttingen on Sunday two weeks ago to spend some days hacking and meeting up with the other developers before the start of SambaXP. It was really nice to see everybody again after more than 7 months.

SambaXP was a bit different this year. There were three tracks during the second part of the conference this year, one more than previously and of course, there were several engineers from Microsoft attending this time! Some of the interesting talks this year included Julien's update on OpenChange, Tridge's talk on PFIF, the talk from the likewise folks and of course the talk from Microsofts' Wolfgang Grieskamp on SMB2. We also had some other informal discussions with the Microsoft folks about specific topics - very useful!

There are some photos up on the SambaXP homepage. And just to be ahead of the comments: yes, I know I need a haircut.

I did some initial work on several bits and pieces of code that I hope to expand over the next few months. Volker has started working on ncacn_ip_tcp support and I have been working on making the Samba 3 DCE/RPC library compatible with Samba 4. This should allow OpenChange to use Samba 3 in the future.

Guenther, Wilco and I made some initial progress on the policy library, allowing client-side manipulation of (group) policies in Samba. I worked with Simo on trying to get rid of an evil hack in Samba4's event subsystem.

David Holder blogged about some of the IPv6 development that we did during the conference: http://www.ipv6consultancy.com/ipv6blog/?p=34

And lots of other things I can't remember at the moment...

After the conference Andrew, Wilco and I drove back to the Netherlands and I played tour guide for a bit showing Andrew around the country during the afternoon and hacking Samba together in the morning. Later this week we took the train to Brussels, Eurostar to London and visited Sam's company in the UK Midlands for a couple of days.

And in the midst of all this, it seems Ubuntu Hardy was released. Congratulations to all those involved!
