Why OpenBSD's Release Process Works
An anonymous reader writes "Twelve years ago OpenBSD developers started engineering a release process that has resulted in quality software being delivered on a consistent 6 month schedule — 25 times in a row, exactly on the date promised, and with no critical bugs. This on-time delivery process is very different from how corporations manage their product releases and much more in tune with how volunteer driven communities are supposed to function.
Theo de Raadt explains in this presentation how the OpenBSD release process is managed (video) and why it has been such a success."
Basically, they only allow developers who are willing to sit through a 30-minute video to work on their software.

but at least he is stubbornly consistent. Without it, openBSD would not exist in its current fine form.
That video can serve as a lesson to others on how to manage a project for an extended period of time and keep things consistent and predictable.

What I got out of it was that the core developers, not some other group, do the testing. Rather than hand the task of quality control/testing to some other group just prior to release, all developers are held to a high level of participation in this regard. Theo and other developers use nightly builds in their day-to-day work and the entire system compiles most every night.
That was a William Shatner video.
Fascism starts when the efficiency of the government becomes more important than the rights of the people.
Two points:
1) they do not create a separate branch for a release. The release stays in TRUNK until it is released. This has the advantage that ALL developers are working towards a release. Introduction of features is slowed as a release approaches. He does not address the disadvantage of this system: that many developers sit around idle when their work is completed early during this phase.
2) Everyone tests. There is no test team. All developers test things before a release. He does not talk about agile and how everyone should be testing their own stuff anyways.
Point 1) was interesting. It works for them because they are volunteer based. They are not paying the salaries of the idle developers during the release phase. It would not work in a corporate environment because those people are to valuable to be underutilized.
NOTE: I did not listen to him talk... just read his slides.
Hi Theo!
Let's compare --
Linux (1991--present): The code base has never forked. The release process has remained largely in the hands of Alan Cox and Linus Torvalds throughout its history, and except for some cosmetic differences, patch submission and integration has been handled the same way. Most people consider the two head developers and various major contributors to be, on the whole, pretty nice guys, though the snafu with loading binary blobs, and the driver architecture supporting 'non-free' elements in kernel-space was notable for the high level of frustration on all sides.
OpenBSD (1994--present): Forked from NetBSD (1993--present), who forked from 386BSD (1992--1994), that originally derived its codebase from BSD4 (1977--1995). The history of BSD is a blood-bath of politics leading to forks; Most of the developers of the *BSDs are variously referred to as "difficult, abrasive, etc.," although Theo, to his credit, has had a major change in reputation over the past several years.
Historically, the BSD variants have enjoyed a smaller uptake in the market and casual open source contributors find it difficult to get involved because of cultural/political differences. They also tend to fragment, as noted by the number of variants, which further weakens their position. Linux, on the other hand, likely enjoys a much broader userbase and more contributions due to its more relaxed community standards and the general approachability of its core team. I would say the "release process works", but by feature count, contributions, and hardware support, the process is full of fail. Does that mean it's a failed project? No--I'm just saying that the differing priorities and political/cultural values held by the core developers has had an overwhelming impact. Businesses might appreciate the consistency of the release schedule and the relatively bug-free nature of those releases, but looking at market share it's pretty clear those are not the priorities for most businesses.

Not that that would be a bad thing. The majority of people in the world are average, by definition. When a truly extraordinary person tells them what to do, and they shut up and do it, the collective ability of the group is far greater than the mere sum of its parts. If the extraordinary person happens to be a bit of a knob, that's irrelevant if they are all focused on the desired result and not their own silly little egos.
"Oh noes, he told me my code was stupid and wants me to to it again! Cry cry cry!"
If Theo tells you your code is stupid, then it is. End of story. Do it again. Yes, there are better ways to deal with people, but seriously, Theo gets knocked for his personality not because it's really that big a deal, but more because ordinary people are jealous of his enormous capacity.
Get over it people. Theo's good at what he does, OpenBSD could and would not exist without him, and the world is a better place for it.
I hate printers.
Long story short: Theo rules with an iron fist and springs releases like pop quizzes.
How we know is more important than what we know.

1. code freeze happens every six months meaning you don't get to finish off features and fixes which might have been of huge benefit. it would make much more sense to base your release cycle around features and improvements, then some arbitary number of days.
2. openBSD EOL's it's releases so quickly, that only in the very rare instance that a business is willing to pay through the nose for inhouse support will you be able to see your system patched.
3. 6 months is way WAY too short of a time for a whole new release. 12 months (if you have to go with the retarded time based release) would be much less of a drain on resources as there is a certain amount of work that must go into a release wether it's got useful upgrades or not.
i've used openbsd in production environment, and it doesn't cut it in hardware support or speed. it's firewall was nice, but i've got that in freebsd now which is a far better OS.

No wacky and nutty GPL kooks.
But in return you get wacky and nutty BSD kooks.
No screaming diatribes over 'purity' of ideology.
You don't know who Theo de Raadt is?
No foaming at the mouth tantrums that someone is using your code and not kissing your fat ugly ass in reverence.
You definitely don't know Theo de Raadt.
The efforts the GNU crowd has done to keep open source developers locked into their compiler is sickening from anyone who likes to believe the open source world is some sort of technological marketplace of ideas compared to the Microsoft world.
Yeah, how dare they make a superior product, couldn't they have made GCC suck a bit more so the alternatives wouldn't look so bad?
Every BSD project I've followed or participated with has been a positive experience due to those types of licensed projects attracting engineers who just want to write good code and want their code to be available and free to everyone to make good use of it.
Same here, and the same goes for GPL'ed projects. In all cases, its the users (and the ocassional Slashdot troll) who make them look bad. Well, except for Theo's yearly foaming-at-the-mouth, but he's such a talented engineer we're ready to let that one pass.
No problem is insoluble in all conceivable circumstances.
I could be wrong, but I think the primary reason they release so fast is because the OpenBSD team does not attempt to bundle all of existing open source software with their OS like say Debian is trying to do. In *BSD distros, there is the core OS that includes essentially only the operating system and some utilities, and then there is the ports collection. I believe a serious bug in some port package will not halt the release process of a BSD distribution, at least for non-essential ports.
It would be pointless to test prior to integration of all submitted components.
Stay away, stay faaaaaaar away from my code and applications.
