Help with a Firefox plugin

Michael W. Lucas is looking for someone to improve the Extended DNSSEC Validator.  Specifically, add BSD support.  It’s an idea worth supporting, because the standard it works with makes self-signed certificated perfectly feasible.

DPorts packages for 64-bit DragonFly available

If you want to take advantage of the binary packages of DPorts, and have a x86_64 system with a recent DragonFly 3.3 on it: Francois Tigeot has you covered.  There’s no i386 packages yet, which are the ones I could use right now, darnit.

If you want to try DPorts, see my earlier article.

Read shortcut, buffer cache improvements

The new vm.read_shortcut option has been turned on by default by Matthew Dillon, which should lead to some performance improvements.  That improvement has been measured for tmpfs, at least.  There’s also some buffer cache improvments that help on x86_64 systems, too.

Update: As Venkatesh Srinivas pointed out, tmpfs also no longer uses the mplock, so it’ll take better advantage of multiple processors.

Two pkgsrc changes

There’s two changes in pkgsrc recently that might affect you: graphics/png was updated, so many dependent packages will require recompilation.  Also, editors/emacs was moved to a general package instead of being specifically named by version, so now you can install ‘emacs’ instead of ‘emacs24′ or whichever version.

a pf question on VoIP

I have a pf question for anyone who is interested.  I have this setup in my /etc/pf.conf, to prioritize my VoIP link.  (this system also does NAT.)

ipphone = ""
altq on $extif cbq bandwidth 768Kb queue { std, voip }
queue voip bandwidth 168Kb priority 7 cbq(borrow)
queue std bandwidth 600Kb priority 1 cbq(default)
nat on $extif from $intif:network to any -> ($extif)
pass in quick on $intif proto udp from $ipphone to any tag VOIP_OUT keep state
pass in on $intif from $intif:network to any keep state
pass out on $intif from any to $intif:network keep state

pass out on $extif tagged VOIP_OUT keep state queue(voip)
pass out on $extif inet proto tcp all modulate state flags S/SA queue(std)
pass out on $extif inet proto { udp, icmp, gre } all keep state

When I run this, ‘pfctl -s queue’ shows most of the data getting run through the ‘voip’ queue.  I unplug the ATA, I still see the number of packets going up.  It seems packets are getting tagged that shouldn’t be, but I’m not sure why.  Anyone else have a similar – but working – setup?

Update: it was the underscore character in the tag.  Everything matched it, it seems.  Removing that made it work as expected.

Xen users, take note

Markus Pfeiffer reports success using Xen HVM to run DragonFly, which may be useful for any of you Xen users.  He reports not being able to use more than 2 virtual CPUs, though Scott Tincman reports successfully using 4 (with qemu), so your mileage may vary.

Updated: noting qemu usage as Markus pointed out in comments.

Lazy Reading for 2013/01/13

It’s a very short week this week.  I was on the road for work, so I didn’t see anywhere as much of the Internet as I may have liked.  Count my dports writeup yesterday as part of this and it averages out to a good amount of reading.

  • Favorite Linux Commands.  Not all of them are Linux/bash specific.  (via)
  • Advanced Vim Registers.  Or buffers, or clipboards, if you want to get messy with terms.  (via)
  • “I hate BSD so much!”, he yelled at his spittle-flecked monitor.
  • TOME, a roguelike.  Read through the comments for discussion of many other roguelike games.

Your unrelated link of the week: New Tokyo Ondo.  via Jesse Moynihan, whose Forming comic on that site is an epic read.  Epic, as in it’s actually telling a NSFW world creation story.

An early DPorts education

John Marino’s DPorts project, mentioned here briefly before, is interesting.  I had two separate people ask me how it works, so a better explanation is in order.  I’ve tried it out on a test machine over the past few weeks.


Dports is an effort to use FreeBSD’s ports system as a base for DragonFly, and the pkg tool as a way to manage binary packages built from DPorts.  This is complicated, so I’ll explain each part in order.

  • FreeBSD ports are a FreeBSD-specific collection of software installation files that automate building 3rd-party software on FreeBSD.  You’ve probably already heard of them.  (Note there’s no mention of DragonFly.)
  • DPorts is a collection of files that map to existing FreeBSD ports, and contain any changes necessary to make that port also build on DragonFly.  Many of those programs build without changes on DragonFly.  DPorts builds from source.
  • pkg is used for package management, and is usable on FreeBSD and on DragonFly.  The binary packages produced from building with DPorts can be installed from remote locations and managed separately using pkg, so that software upgrades and installation can be performed with binaries only.  (It’s much faster that way.)

Every port seen in DPorts is known to build on DragonFly.  John Marino adds a port only after it builds successfully, using poudriere as a bulk software tool.   Ports are only updated to a newer version when that newer version builds, too, so once something arrives in DPorts, it should never break from being updated at some point in the future.


To use DPorts, you need two things:

  1. DragonFly 3.3 or later, though 3.3 is the most recent right now.
  2. You need to rename /usr/pkg so that your existing pkgsrc binary programs don’t get accidentally used while working with DPorts, causing confusion.  If anything goes wrong with DPorts when you are installing it and you want to go back, remove all the DPorts packages and rename /usr/pkg back to normal.

(Don’t confuse pkg, the management tool, with /usr/pkg, the normal installation directory for pkgsrc. ) For the installation of the base port files:

cd /usr
make dports-create-shallow

If you’ve already renamed your /usr/pkg directory, git won’t be in your path any more.  You can instead download a tarball and unpack it, which also happens to be possible automatically via that same Makefile.

cd /usr
make dports-download

Downloading via git is fastest, so if you do need to use the tarball via make dports-download, build devel/git, delete /usr/dports, and then pull it again with make dports-create-shallow.  This all comes from John Marino’s Github site for DPorts.

Managing DPorts

DPorts doesn’t use pkg_info, pkg_add, and the other tools traditionally seen on DragonFly for pkgsrc.  Instead, package management is done with pkg.   Use pkg info, pkg install, pkg remove, and pkg update to list, install, delete, and upgrade various packages on your system.  Packages built from source or downloaded as prebuilt binaries are managed the same way, using these tools.

See some of the other writing about pkg for FreeBSD for details on how it works.

Since DPorts doesn’t update a package until it gets a successful build, and installations are of successfully built binary packages, upgrades with prebuilt packages should always succeed.  Since they’re binary, they should be fast.  There’s a lot of ‘shoulds’  in this sentence, but these are reasonable suppositions.

What about pkgsrc?

Pkgsrc and DPorts shouldn’t be used at the same time, since one system’s packages may be at different versions but still get picked up during building for the other system.  That’s about it for restrictions.

I intend to try building an experimental release of DragonFly with DPorts, to see if all the right packages can be added, but no guarantees.  DPorts is brand new and does not yet have a repository for downloading packages, so the normal caveats apply; don’t install it on a mission-critical machine, and be ready to deal with any surprises from using it if you do try it out.

What packages are available?

Browsing the Github repo will show you all listed packages.  More complex packages like xorg, openjdk7, and libreoffice install, as does xfce.  Parts of KDE 3 and KDE 4 are in there.  (I haven’t tried either.)  I’m not sure about Gnome, but I don’t think anyone ever is.  There’s no vim, but there is emacs.

That’s just what I see at this exact minute.  It changes daily as more packages are built.  Changes from DragonFly builds are sometimes relevant to the original FreeBSD port, so there’s benefits for everyone here.

What next?

Try it now if it has all the packages you need, or wait for a binary repository to be created to speed things up.  Remember, this is a new project, so a willingness to deal with problems and contribute to fixes is necessary.

Using gcc 4.7 and pkgsrc

If you were thinking you wanted to try gcc 4.7 with pkgsrc, John Marino’s described the option you need to set.  It only works in pkgsrc-master  right now (because of changes John made), and not every package in pkgsrc will build.

The advantage is that it’s also possible, with the same syntax, to set pkgsrc to build with gcc 4.4.  This means the default compiler in DragonFly can be changed to gcc 4.7 and pkgsrc packages that aren’t compatible can still be built.

Update: Check this minor change: ‘?=’ instead of ‘=’.

How to grind that axe, for donations

Whomever submitted this story to Slashdot really doesn’t like FreeBSD; they’re describing FreeBSD’s annual end-of-year fund drive as failed.  The month-long drive is only about a week old and has already picked up donations at a faster rate than any previous year’s donation drive, but apparently the poster – and Slashdot’s editors – can’t be bothered to do math.  While we’re on the topic, donate to the FreeBSD Foundation; they do good things.

(There’s DragonFly too, though we’re not as ambitious or officially 501(c)(3) non-profit.)

Another set of benchmarks

There’s more benchmarks for DragonFly vs. other systems on Phoronix.  It has the same problem as previous benchmarks; some of the benchmarks may have no connection to reality (what does the “Himeno Poisson Pressure Solver” actually test?), and almost every system has a different version of the gcc compiler.  So it’s meaningless in terms of comparative or absolute performance.  On the other hand, DragonFly doesn’t do badly.

You can also look at the comments to see someone absolutely freak out over the very existence of things that aren’t Linux.  I’m not sure if it’s actually trolling, since the comments are so exactly wrong.

More benchmarking on Phoronix

Because of the recent good results for pgbench on DragonFly 3.2, Phoronix has a new benchmark of DragonFly using other (possibly unrelated) tests.  There’s not a lot of information to glean from them; they are testing operations different than what was optimized for pgbench in 3.2.  I’d like to see DragonFly 3.0 tested the same way to see how much improvement there was between versions.

Clang-Day today for FreeBSD

Today is the day that FreeBSD moves to using clang by default.  This is not necessarily a surprise, but I like the finality of calling it “Clang-Day”.   I think Clang will probably be the next compiler brought into DragonFly’s base system, instead of the next release of gcc.  Don’t make any bets on my statement, though, cause I certainly won’t be the one doing it.  (It’s hard.)

If we only had the spiffy name…

I mentioned this before in the Lazy Reading from last Sunday, but it’s worth a second look: Apple’s new Fusion Drive product appears to be very much like DragonFly’s swapcache.  DragonFly doesn’t have exclusive right to the idea of caching on a faster disk, clearly, so I’m not complaining that it’s “ours”.  It’s frustrating to see product announcement/press releases stumbling all over this like it’s a new thing.

Then again, having new ideas about technology ideas and making sure they spread is one of the points of the BSD license, so perhaps there’s no good reason to complain at all.

(Before anyone reads too much into this: No, I don’t know of any direct relationship between swapcache and Fusion Drive; they may have no common background other than structure.)

Remember: bin-install

A thread on pkgsrc-users@ reminds me: adding a specific line for bin-install will save time when rebuilding packages; pkgsrc will use existing binary packages instead of rebuilding from source when possible, when this is set.  At least, I’m pretty sure that’s what it does.

From make to bmake

John Marino is working on a very good idea: bringing bmake into DragonFly as a replacement for the current ‘make’.  bmake is going through more active development and apparently also in use/will be used? on FreeBSD, so syncing up with the same make flavor as FreeBSD and NetBSD will help everyone.  It’ll also remove the problem where you ‘make’ everything in DragonFly, except pkgsrc packages which you ‘bmake’.  It’s not changed over yet.

(What does OpenBSD use for make?)

OpenMPI, OpenMP on DragonFly

A conversation about compilers in the DragonFly base system led peeter (must) to describe his group’s use of OpenMPI on DragonFly for physics calculations.  Apparently he’s had a significant performance improvement on DragonFly.

Along similar lines, John Marino helped out by bringing in libssp and libgomp for gcc 4.7 for use with OpenMP.  (This is in DragonFly 3.3, not 3.2).

gcc 4.7.2 and pkgsrc, a test

John Marino did a bulk build of pkgsrc using gcc 4.7.2, and posted the results.  The result?  About 1% of packages that built with gcc 4.4 did not build with 4.7.2.  Whether that’s a problem with gcc or a problem with how each of those software packages were created by the original authors, I don’t know.

Structure change, full buildworld

If you’re on master (or the 3.2 branch) of DragonFly, you’ll want to do a full buildworld/kernel.    There’s been a pmap bug that looks like it’s fixed, but the changes have some repercussions.  It may be possible to just recompile kgdb, but I like to overcompensate.

As I typed elsewhere, my general plan is to branch DragonFly 3.2 on the 8th, and release on the 22nd.  That should give the recent scheduler and gcc work a chance to settle, and perhaps get a new version of USB support in too.  It will probably be using pkgsrc-2012Q3, also, though we may not have binary i386 packages.  3.2 is shaping up to be a much more significant release than I expected.

Posting but not reading mailing lists

The old mailing list software for mailing lists, bestserv, apparently allowed people not subscribed to a list to post to it, after answering a confirmation message for each message posted.

The closest way to duplicate that for Mailman is to sign up for the list you want, and then turn off mail delivery for your email address in the config page for that mailing list.  This won’t affect a lot of people, since most people want list output in their mailbox, but there’s at least a few I’ve fixed that way.

SYSV shared memory vs. mmap

Francois Tigeot benchmarked the recent Postgres 9.3 release.  Postgres apparently switched to using mmap instead of SYSV shared memory, and Francois has done this to show the performance differences.  (view the PDF in his post.)  Of course, work has continued since this was posted, so there should be new numbers soon, and new changes I’ll document in a future post.

I haven’t found a reference to the exact decision Postgres made on how to handle memory; please post a link in comments if you know a good source.

If you ever wanted to read an extensive discussion about the scheduler, today’s your day.  Mihai Carabas, who posted the details of a long discussion he had with Matthew Dillon about how the scheduler works.  You may recall Mihai’s name from the very successful GSoC scheduler project that recently finished.

(look, a link to the new Mailman archive!)

Mailman conversion for DragonFly mailing lists complete

All the mailing lists at have been converted over to Mailman.  The old archives are still functioning, and will continue to update until I can find enough old material to retroactively complete the Mailman archives.

Mailman conversion for mailing lists

If you’re on any of the mailing lists, I’m converting them over from bestserv to Mailman.  I’ve done bugs@, commits@, hammer@, and test@ so far, and I’ll move the old archives over to the same format as soon as I find an actual mbox file with the old messages in it.  The remaining lists should be tomorrow.

(If you got a note tonight from a list you were sure you were unsubscribed from, that was my fault; sorry!  I didn’t understand the format of the bestserv user lists.)

A whole bunch of installation notes

DragonFly user varialus has created a page on the DragonFly website (it’s a wiki, after all) with all the notes taken from trying installation, etc.  There’s far more notes than I expected there, so it’s worth a read.

3.0.3 images up

I’ve uploaded DragonFly 3.0.3 disk images, both ISO and IMG.  They should start appearing on a mirror site near you in the next 24 hours.  This took a while after the tagging, I know, but I wanted to make sure every one of them booted.  I didn’t on a previous release, and regretted it.

Postgres benchmarking again

Francois Tigeot benchmarked several different operating systems using Postgres 9.2b3, including DragonFly, and published the results.  I have a local copy of the PDF since the attachment didn’t really survive the archiving.  Follow the thread for discussion.  The Linux results look abnormally high, so it is possible that something different is happening on that platform…

DragonFly and GSoC 2012 wrapup

DragonFly had a successful Google Summer of Code even this year.  It marks our 5th time participating, 7th if you count  Google Code-In events.

Mihai Carabas worked on adding SMT/HT awareness to the DragonFly scheduler.   This project was very successful.  The original goal was just to take advantage of threading with the scheduler, but the benchmarks published by Mihai show in general a 5% speedup from these scheduler changes.  His work has already been committed.

Vishesh Yadav implemented an inotify interface in DragonFly.  inotify is an originally Linux-based system for monitoring files and directories for changes.  A specific use for this is an inotify-aware locate program, so that a list of file locations can be kept ‘live’.  His code for the inotify interface should be committed to DragonFly very soon.

(This was written in part for Google to use on their Open Source Blog.)

Planning for the next release

3.2 is the next major release of DragonFly, which will be relatively soon by the every-6-months release schedule.  John Marino’s put together another catch-all bug report for that release.

Another LiveDVD image

Sascha Wildner’s been working on his own DragonFly live images, in DVD or USB form.  It uses XFCE along with a number of other packages listed in his post.  They are .xz compressed, so they are nice and small for download, but make sure you have something that knows that format.

GSoC week 9 reports

Mihai Carabas has posted his weekly results, showing a 5% improvement in pgbench resultswhen using his scheduler.  Vishesh Yadav is working on IN_MOVED_TO/IN_MOVED_FROM flags (part of inotify, I assume).  Ivan Sichmann Freitas I haven’t heard from yet.  (Ivan, where are you?)

MaheshaDragonFlyBSD now available

Juraj Sipos wrote me to describe MaheshaDragonFlyBSD, a live DragonFly image that has additional software preinstalled, and can easily be set to understand Sanskrit.  It’s available in DVD and USB versions.

Summer of Code status, week 7

Here’s the regular status updates for Mihai Carabas (scheduler) and Vishesh Yadav (inotify).  I don’t have the update from Ivan Sichmann Freitas yet.  Here’s Ivan Sichmann Freitas.

Here’s a way to donate

If you want to put something towards DragonFly, and you don’t have time or hardware, cash is now an option.  (It’s not tax-deductible.)
