Jan Lentfer’s done some new benchmarking of PostgreSQL on Hammer. There’s further suggestions and a more complete benchmark is planned, taking advantage of the Hammer improvements in 2.6. In the meantime, you can look at previous benchmarks.
If you’re a potential Summer of Code student, there’s about 72 hours left in the student application period. Get it in there!
DragonFly 2.6 is out! Download from a mirror, check the release page, and enjoy the large number of new features. There’s a full set of binary packages built, too.
Technically, this is 2.6.1, since 2.6.0 was tagged a week ago and 2.6.1 has all the last minute fixes since then.
Gource is a tool for visualizations from version control history; the video page has some examples. (via) I’d love to see this run on DragonFly. I’m curious to see what would happen on a huge, old repo, like NetBSD. Please hlep me, intarwebs!
2.6 will probably be out within the next 24 hours. We’re just waiting on the packages, though we’re probably in the clear already.
Be ready for mild confusion with this and the current Linux kernel. I know it’ll happen.
Daniel Lorch has ported Hammer to Mac OS X, of all things. It’s not complete, but he’s moving right along.
Daniel Lorch’s work on porting Hammer to Linux (read-only, currently) has been moved to a new location.
Alex Hornung posted a followup about his I/O scheduler work, with some interesting ways to watch the state of your disk’s activity.
Alex Hornung has posted an elaborate summary of his I/O scheduler work, with details on usage. He reports speed improvements under heavy load. If this sounds interesting to you (and it should), it’s possible to test his changes right now.
OpenSSL (which recently hit 1.0, though that’s not in DragonFly yet) has been patched to cover a recent security issue, thanks to Peter Avalos.
Jan Lentfer’s updated BIND to 9.5.2-P3, too.
Venkatesh Srinivas’s new sysctl, “debug.panic” is available for those who want to panic their machine on purpose, but don’t have direct access to the keyboard.
A problem found by Jan Lentfer and fixed by Matthew Dillon means that you can get a good performance boost if you’re running bleeding-edge DragonFly from the last month or so. Or, you can just wait a week for the 2.6 release.
Alex Hornung has been working on an I/O scheduler; he’s made some graphs to show results so far. They’re plain, but pictures are always fun.
DragonFly 2.6 has been branched, and should be released next week. Check the tag message for a list of the many, many commits.
Thanks to work from Samuel J. Greear and Alex Hornung:
- Install Firefox (natively)
- libflashsupport and adobe-flash-plugin
- mount linprocfs
- null mount devfs within the linux system
There’s occasional video and audio sync problems, but Johannes Hofmann has already found a fix.
This set of graphs that shows relationships within given languages on github shows some interesting relationships, and also happens to be very pretty.
Would it be worth moving DragonFly to github for the additional services? I’m not qualified to answer.
Alex Hornung has suggested replacing the existing bugtracker (Roundup) with a new one (Redmine). His post about the changes is lengthy and links to a demo, so read on for details; I haven’t had a chance to look at it in full, yet.
YONETANI Tomokazu has eliminated cvsup, replacing it with net/csup from pkgsrc. The README notes that the pkgsrc package devel/cvsync is another alternative if you need to retrieve the repository and not just the checked out files..
Matthew Dillon has implemented what he calls “REDO” records in Hammer, which reduce the amount of time taken flushing data to disk. It’ll be in the 2.6 release, but it isn’t on by default.
Jordan Gordeev’s work on 64-bit vkernels has also been brought in, so virtual systems are now available for x86_64 users.
Matthew Dillon’s added some tools for building system snapshots, a previously custom process. Look at the README for details.
