Venkatesh Srinivas has a large writeup describing just how the memory allocator in DragonFly changed from 2.6 to the upcoming 2.8 version. In all that text, you may notice the cheering statistic that it gave a 20% improvement in sysbench results.
Siju George found no equivalent of OpenBSD’s ‘afterboot‘ quick-start page in DragonFly, so he went and created it himself. Go, read.
YONETANI Tomokazu wrote out a nice explanation of acpi(4) and the myriad ACPI subsystems which can be enabled or disabled at boot time. If you do have booting problems, it’s usually ACPI, and it’s usually only one small part. Finding that small part is easier with this list.
Rumko came up with some changes for vkernel(7) that, among other things, made it possible to run them diskless; almost like booting a thin workstation.
Found via a random Google search: SSHGuard. It’s not available in pkgsrc, but it’s in other BSD packaging systems, and it lists DragonFly on the site as a possible host. It monitors various services and blocks access to overly aggressive connections using (on DragonFly) pf. This is similar to scripts discussed here in the past. It also may be useful in light of the recent FTPd problem.
OpenSSL on DragonFly can now dynamically load engines (cryptographic support modules) at runtime, thanks to Peter Avalos.
Something that always got with with Linux binary support was that I couldn’t get the Linux /proc filesystem to automatically mount on boot. I’d end up doing it by hand later, right after I tried to start a Linux binary and had all sorts of issues. Pierre Abbat had this same problem, and Sascha Wildner has the answer: “linux_load=yes” in /boot/loader.conf.
If you were thinking of buying a Western Digital Passport USB drive, it’s supported on DragonFly, thanks to Dylan Reinhold and Alex Hornung.
For those using the release version of DragonFly, the new C-based loader in 2.8 will look like this. Well, not exactly. This is from a proposal from Alex Hornung that removes some extra lines, but I expect this is what you’ll see.
Matt Dillon and Venkatesh Srinivas conspired to fix another nmalloc issue, which should resolve any remaining problems people were having with Firefox, and possibly other applications as well. Due to an oversight of sorts, all locking operations on nmalloc’s depot were ineffective, as if there were no locking at all. Curiously, it worked remarkably well considering such a large race condition was present.
Here’s something: Pratyush Kshirsagar came along, saw the proportional RSS project idea, and did it. It’s nice to have a completed project just sort of fall out of the sky.
If you run any flavor of BSD, you should make sure your ftpd is off, as Mathias Schmidt points out based on this recent security advisory.
I’m going. Venkatesh Srinivas is going. Who else is interested? (See the site.)
When compiling software on DragonFly but outside of pkgsrc, and you have trouble with configure, remember you can always manually pull down new versions. You’re welcome, future me.
I’m linking to this commit message from Matthias Schmidt simply because it has the correct invocation for installing a vkernel, and I know this will come in handy, someday.
Chris Turner wrote some notes about building pkgsrc packages in a chroot, including the handy tip of using
DISPLAY=:0
to run and display a GUI-using app under the chroot.
Based on a recent project list entry for “changing the vm_map lookup” (currently last item on the page), Venkatesh Srinivas wrote up a bit more information on it, linking to different strategies for arranging the data. Good reading for those who like data structures.
Matthias Schmidt has set up a x86_64 DragonFly machine at uther.dragonflybsd.org. Anyone wanting to try 64-bit testing can use a vkernel on that machine. Mail him for an account.
