A BSD auction


The very first copy of Absolute OpenBSD (2nd edition), signed by Michael W. Lucas, is being auctioned off in a charity event for OpenBSD.  There’s 5 days left to bid, though the price is already somewhere north of $2 per page.

Summer of Code links for everyone


The DragonFly page on the Summer of Code site is set up.  If you are a potential mentor that I’ve talked to before, I’ve already sent you an email with details.  If you are a potential mentor I haven’t talked to, you can email me or send a request via the DragonFly page.  (Google has a new ‘connections’ method for signup this year.)

If you’re an interested student, take a look at the DragonFly Projects Page.  Keep in mind that your proposal does not have to be one of those ideas – new projects are always welcome, and often have the advantage of being unique instead of being one of several similar proposals.  (hint, hint)

bxr.su announced


Constantine Aleksandrovich Murenin has put together a new site, bxr.su.  His announcement to users@ goes into a lot of detail, but here’s a preview: it’s an OpenGrok site that has a forked version of OpenGrok that’s both speedy and takes BSD into account, along with other nice features.

Here’s the catch: it’s currently IPv6 only.  IPv4 will be on as a test just today, and on for good shortly after.  Read that announcement I mentioned for details.

Testing out the DragonFly 3.4 release candidate


If you have a DragonFly 3.2 system and you want to try the 3.4 release candidate, you can delete your local source, edit the Makefile to pull down 3.4 instead of 3.2, and run it.

cd /usr
rm -rf src
vi /usr/Makefile;
(in vi) :%s/DragonFly_RELEASE_3_2/DragonFly_RELEASE_3_4/g
(save, quit vi)
make src-create-shallow

… then proceed to make buildworld and so on, as normal.

The caveats: I haven’t tested this yet, and this assumes you don’t have any local changes in /usr/src that you want to save.  The usual warnings about lighting your computer on fire, etc., apply.

pkgsrc-2013Q1 available via DragonFly git


The DragonFly Git repository of pkgsrc now has the 2013Q1 branch.  You can switch to it by editing your /usr/Makefile (look for existing references to either pkgsrc master or pkgsrc-2012Q3) and using the normal commands.

DragonFly 3.4 branched


DragonFly 3.4 is branched –  as a release candidate, with the current target for 3.4.0 release as the weekend of April 13-14.  See the tagging commit note for a list of all the commit messages.

Note that in previous releases, we tagged “x.y.0″ on branch, and “x.y.1″ on release.  I’m now tagging “x.y.0rc” for the release candidate at branch time, and we’ll tag with a more normal (to my ears) “x.y.0″ for the release.

If you build a 3.4.0rc image right now, you’ll get an older quarterly release of pkgsrc.  That’ll be changed tomorrow as the DragonFly pkgsrc git source is updated and I change where 3.4′s  /usr/Makefile points.

pkgsrc-2013Q1 announced, with extras


The 2013Q1 branch of pkgsrc has been announced.  Along with the normal quarterly material, there’s several notes: preliminary Cygwin support is present, ruby 1.8 will be retired in favor of 1.9 after this release, and the pkgsrc.org web page now has a very nice new look and logo.

I plan to branch DragonFly 3.4 very soon, and that version will have 2013Q1 as default.

Update: The 2013Q1 branch should be available by tomorrow on DragonFly’s git; the repository needs to update and convert from NetBSD’s CVS and that takes a little time.  I’ll post when it’s ready.

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.)

extif="em0"
intif="nfe0"
ipphone = "192.168.0.101"
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.

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.

Background:

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.

Installing:

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.

Maintaining a wiki for fun


The Open Graphics Project, which is building a completely open video card, needs a wiki maintainer.  It’s a volunteer effort.  If you were perhaps thinking you wanted to step up to a more complex project but didn’t want to just be writing code, here is a perfect opportunity.

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.

I’m planning for DragonFly 3.2 to come with pkgsrc-2012Q3, the most recent release.  I’m building binary packages to match, and the build should complete by the time we release on the 22nd…

3.2 branch and release plan


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.

www and bugs down, other services up for dragonflybsd.org


The machine that runs www.dragonflybsd.org and bugs.dragonflybsd.org is currently down.  While it gets figured out, Alex Hornung has a static copy of the dragonflybsd.org main website available.

Some kernel hacking for you


Sepherosa Ziehau has some suggestions for anyone looking for some kernel hacking.  They’re mostly based around busdma(9).

dragonflybsd.org appears to be down right now so I’m linking to the MARC kernel@ post.

Broken packages list for pkgsrc-2012Q3


There’s a post on the mailing list tech-pkg@netbsd.org of currently broken packages for the next quarterly release.   It’s not a lot of stuff, but if something you need is on there, don’t worry too much.  If you follow the thread through its replies, there’s a lot of fixing going on.

Users@ shows up at MARC


MARC, which stands for Mailing list ARChives, has a lot of mailing lists.  It now includes the DragonFly users@ list, along with the others.  (It’s not linked in *BSD on the main MARC page yet, but it should be soon.)  It’s worth digging through the massive, massive wall of text on that page to find a mailing list you didn’t know existed.

Rebuild everything if you’re running current


This latest commit for the new scheduler means that on your next update, you will want to build a new kernel, and probably a new world too.  This only applies if you’re running DragonFly 3.1, of course.

Mailing list archives updated back to 2003


I got the old mailing list archives converted to Mailman.  As I wrote in a post to users@, please let me know about problems.  There’s some garbled messages from the old archive that were placed into the 2012-Sept. section for each message; I’ll be cleaning those up manually.

Posting but not reading mailing lists


The old mailing list software for @dragonflybsd.org 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.

A bikeshed and a code change


A discussion of why root automatically lists dotfiles with ls and all other users do not led to a long thread that includes some UNIX history.  There’s some useful and some not-so-useful parts in the thread, but it did indirectly produce a way to reverse the listing effect itself.

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.

Pkgsrc freeze has started


See the note on pkgsrc-users@.  The next quarterly release, pkgsrc-2012Q3, should be fully baked by the end of the month, if all goes well.

When is DragonFly 3.2 coming out?


Probably not for a few weeks, at least.

pkgsrc freeze for 2012Q3 starts tomorrow


As seen in this pkgsrc-users@ post from Thomas Klausner, the freeze for pkgsrc-2012Q3 starts on Sunday and continues for (probably) two weeks before the release.

NYCBUG, RSS, and SMPng


NYCBUG, the NY BSD user’s group, has an RSS feed for their speaker events, found via Dru Lavigne’s always useful BSD Events twitter.  The next event at the start of October is a talk about SMPng in FreeBSD.  Given that it was the project that in part led to the creation of DragonFly, I’d like to hear about it.  (and even better, have someone more qualified than I compare and contrast that approach with what’s in DragonFly.)

A potential new pkgsrc site


If you look at new.pkgsrc.org, you will see what may become a new site.  This is apparently a test, so don’t react as if this was the actual site.

A lot of scheduler talk


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 @dragonflybsd.org 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 dragonflybsd.org mailing lists


If you’re on any of the dragonflybsd.org 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.)
