Sascha Wildner has updated timezone info. Check the commit message, though… apparently, there’s a lot more changes going on with the international system of timezones than I ever expected.
Sepherosa Ziehau’s recent nfe(4) and et(4) changes have made some significant network speed improvements.
Matthew Dillon’s latest Hammer update prevents data corruption when the disk is full. Update, if you are following the bleeding edge.
Hasso Tepper has added Objective C support for gcc 4.1.2.
Matthew Dillon’s latest HAMMER update warns of the usual need for a newfs, but says that the last change requiring this will go in today. Performance is on a par with UFS; this would be interesting for someone to benchmark and graph…
There’s been more talk about HAMMER; the June 13th update led to some discussion of B-Trees, along with HAMMER updates for the 16th and 17th, with some nice performance gains and the normal requirement to newfs if you’re using it.
Peter Avalos has updated libarchive in DragonFly to 2.5.4b. Thanks, Peter!
Matthew Dillon’s posted daily updates for the past three days, so I’ll link them all here:
- June 9th: bugs fixed
- June 10th: Another newfs’ing required
- June 11th: Surprisingly good performance numbers
I think I already read about this, but it didn’t really sink in until I read this commit message: HAMMER will allow multiple physical devices to be mounted as a single volume. Wait! That’s in the wrong tense: it’s possible now.
The new ‘undo’ utility looks equally interesting, though the name may not stay.
Among other HAMMER work, Matthew Dillon has added a “softprune” option. With this option, historical versions of a HAMMER filesystem can be tracked by maintaining a list of soft links. There’s some sort of joke about ‘regularity’ to make here.
Kevin L. Kane came up with a patch to allow raw socket access within jails. It’s been committed, and it now means that if you set the sysctl jail.allow_raw_sockets, you can ping when in a jail.
Peter Avalos has gone and updated less, tnftp, libarchive, libedit, and CAM. Thanks, Peter, for all the work!
Matthew Dillon has made another change to HAMMER, which may (he doesn’t say explicitly) require another newfs. After the first HAMMER release, there will be a clear upgrade path for times like these.
It was recently discovered that Debian Linux had modified SSL encryption to inadvertently generate weak keys from 2006 until very recently. SSH on DragonFly now includes a tool to check for this issue, and will deny people using those weak keys.
Sepherosa Ziehau posted a number of benchmarks to show the general improvements in packets-per-second volume with his recent networking changes. As is appropriate when comparing values, he created and links to lots of graphs to illustrate the improvements.
Matthew Dillon posted another update on HAMMER filesystem progress; the structures are changing enough to require a newfs’ing to any existing HAMMER volumes. There has been a significant speed boost, however.
Matthew Dillon posted another HAMMER status report, with handling a full file system the only remaining major item. It’s being tested now on his backup system. He’s also committing the final disk structure changes, so you will need to reformat any existing HAMMER volumes.
Sepherosa Ziehau has introduced ETHER_INPUT_CHAIN, which apparently gives a “~150Kpps” speed boost.
The Preview tag has been moved up; if you run Preview or 1.12.2, and still have errors building m4 from pkgsrc 2008Q1, add this patch.
