A running description of activity related to DragonFly BSD.
Mihai Carabas posted some benchmarks for his work with the DragonFly default scheduler and hyperthreaded CPUs. The end result, for those who don’t like number analysis, is that CPU-dependent speeds are reliably constant because tasks are being evenly scheduled across available CPUs.
(Well, CPU threads, since this is hyperthreading, but you get the idea.)
Based on a suggestion from Venkatesh Srinivas, tmpfs now uses a red-black tree for directory lookups, and is also now faster. Credit goes to Johannes Hofmann for doing the testing.
Sascha Wildner has synced find(1) with what’s in FreeBSD, which means there’s a lot more options available – see the commit for details. Many of them are for GNU compatibility, and I’m sure I’ll forget them all. I seem to have issues remembering how to use find(1) successfully.
Emacs in pkgsrc is going to be all numbered versions, as in emacs24 and emacs25, etc. Installing just ’emacs’ will get the current default version, which is emacs 2.4 24.1 right now and I think will be emacs 2.5. All this will come after the pkgsrc freeze for 2012Q2 is over, which means it will be next month. Follow the thread on tech-pkg@netbsd.org for details, or to figure out what I said wrong in my summary.
I always talk about vi and vi-like items here, so here’s my ‘equal time’ post.
Update: as several people pointed out, I had version numbers wrong. The story is corrected to make it slightly less wrong.
Riak, an open source distributed database product, is running on FreeBSD at least. It’s probably able to run on other BSD flavors given that it sounds like the developers were actively working in that direction; someone want to get it into pkgsrc?
I think it’s week four, at least.
Mihai Carabas, Vishesh Yadav, and Ivan Sichmann Freitas all have their weekly status reports up for Summer of Code. Unfortunately, Loganaden Velvindron received a great job offer out of the blue, so he no longer has time for Summer of Code. (He plans to continue involvement in DragonFly, however.)
I have such a surplus of links these days that I started this Lazy Reading two weeks ago.
Your unrelated comics link of the week: Elfquest, every issue ever. The dialogue is cheesy but the original art is fun, in a way that grabbed me when I read it at 10 years of age.
I know I already posted that this was on the way, but this time, the quarterly pkgsrc freeze is starting with a detailed announcement. 2 weeks until the next release, if everything goes well.
Sascha Wildner has made it easier to use alternative syntax checking systems as a “lint” make target in DragonFly. His usage of coccinelle, as one of these alternatives, has already found many bugs – just today, for instance.
Is “alternative syntax checking systems” the right phrase for this? I don’t know. “Correctness checker”? My phrases all sound like something you’d read on a government form.
If you’re using some PHP application that requires the old behavior of PHP 5.2, you will need to specify that version of PHP – pkgsrc is moving to version 5.4 5.3 as default, with version 5.4 available. (thanks, Takahiro Kambe for the update.)
If you’re involved in application development or BSD development in any way, and you write about it somewhere on a personal blog or page or publication, please let me know. (justin@shiningsilence.com)
My goal is to point out as much interesting development as possible, and I find that getting notes right from the people that make them is the best way. Trade publications and magazines will skip over that stuff and go to the press releases, but that doesn’t work for BSD. I’ve found better, more interesting writing watching Peter Hansteen’s blog or Trivium. If you have someplace you write about technology, and especially BSD-related development, please point me at your RSS feed.
The freeze for pkgsrc-2012Q2 starts on the 16th of June, as recently announced. Freezes are usually 2 weeks, so that means 2012Q2 should be tagged at the end of June.
Seen multiple places, but Tomas Bodzar was the first to tell me: there’s a new BSD in town, called Bitrig. It’s forked from OpenBSD. The first release is planned for the end of the month, and it appears to have a more aggressive intended development plan than OpenBSD.
This is my 5,000th published post. This Digest has been running for approximately 9 years, so that’s an average of a post and a half per day, for around 3200 days. Yeesh!
Here’s your most recent weekly round of DragonFly/Google Summer of Code updates:
This was going to go into a Lazy Reading post, but then I realized it shouldn’t. Here’s the source: “A Tragically Comedic Security Flaw in MySQL” (via)
The short version: MySQL, compiled a certain way, will allow 1 out of 256 root login attempts to work no matter what. I was going to link to this for the startlingly large number of MySQL installations found allowing connections from the public Internet, which means breaking into any affected servers would be easy. Then I thought about it… I don’t see a my.cnf installed by pkgsrc for at least MySQL 5.1 by default.
To fix this for your own installation, put
[mysqld]
bind-address=127.0.0.1
in /usr/pkg/etc/my.cnf to disallow remote connections. I don’t know if MySQL on DragonFly from pkgsrc is vulnerable to the issue, but it’s a good idea to not allow remote connections to the database, and ought to be on by default.
Or just use Postgres, if possible.
The June issue of BSD Magazine is out as a free PDF download. The theme is the same as last month – security – and there’s a number of other topics covered.
I got to use the ‘roguelike’ tag again this week, which always makes me happy. Surprisingly, it’s not about… that roguelike.
Your unrelated link of the week: I happen to work at a salt mining operation, which leads to some unique problems (more). Mining in the US is regulated by MSHA, which has been cracking down since the Upper Big Branch incident. MSHA issues ‘fatalgrams‘ every time a miner dies. MSHA also shows up on site as soon as possible, which means they are there taking pictures within a few minutes, with equipment still running. It’s essentially crime scene photos, and a little worrying; many of the deaths are of people around my age with similar experience.
Pkgsrc already runs on a large number of different platforms, but that’s not what I’m talking about. In this case, Joyent, which uses pkgsrc internally, has a suggested change that makes binaries usable on both 32 and 64 bit systems. I don’t know if this will go into pkgsrc proper, but it’s interesting to see.
Reading this HAMMER2 commit carefully shows some future plans: remote cluster control, and the ability to mount nonlocal HAMMER2 volumes. A reminder: those are future plans, not what you can do now.
