GPT partitioning is now supported, though Matthew Dillon’s post about it warns that it is very experimental. He also lists some interesting potential projects to go with it.
Matthew Dillon’s committed some initial support for streaming mirroring. With this, two disks can be synchronized over a network link of any speed or reliability – it can be restarted and immediately begin where it left off, and the amount of bandwidth used can be controlled. This sounds neat.
Sepherosa Ziehau’s committed his ETHER_INPUT2 networking upgrades, which moves networking a bit closer to getting out from under the Giant Lock.
Versions of DragonFly later than 2.0 now have bsdcpio, a BSD-licensed version of cpio, as the default version of cpio, instead of the GNU-licensed one. Thanks to Peter Avalos for adding it.
Matthew Dillon made some last-minute changes to Hammer mirroring;Â it’s made the options a lot simpler.
Matthew Dillon posted a July 16th Hammer update where he details causing a lot of write activity on a USB-connected, Hammer-formatted hard drive, and then yanking the USB connector out. Apparently, doing that 50 times over didn’t even faze Hammer. (Of course, be careful trying that with power.) He’s been committing a lot for Hammer, along with Sascha Wildner and Thoman Nikolajsen. A side benefit is that the Hammer work has exposed some issues in CAM.
Bonus link: Matthew Dillon talks about ‘purposeful destabilization‘, and man pages for hammer(8) and mount_hammer(8) are now available online.
Matthew Dillon’s latest commit of mirroring for Hammer has some details on how it works, for the curious.
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!
