Thanks to Xin Li, gzip now supports pack and can unpack archives in that format.
Peter Avalos has made it possible for TCP buffers to be automatically sized according to need, which improves performance when latency goes up. It’s already in.
Release 2.3.2 has been tagged, for anyone who wants to stick with DragonFly past the current release but before the recent radical changes to NFS. Check the commit message for a summary of what’s changed since 2.3.1, taken from the commit messages.
Well, default as of the next release. With the recent changes to NFS, TCP will be needed in most circumstances. It’s still possible to force UDP if desired with the ‘mntudp’ option, or ‘udp’ if you’re using a 2.3.x system.
It is now possible to mount a Hammer PFS via NFS, though you’ll want to use NFSv3.
Peter Avalos has updated gzip, with a far longer list of updates than I would have thought possible with a utility that’s been around for a while.
Matthew Dillon made some major changes to NFS, which have greatly improved speed. He’s also made the clients able to write asychronously, which can overwhelm a server because of this increased throughput. Be careful.
Hey, look at what Michael Neumann’s doing: making Hammer expandable! It will be possible to expand your Hammer volumes while online, even.
(note: it’s experimental; don’t be surprised if it destroys data.)
DragonFly has its first 10G network driver, mxge(4), for the Myricom Myri10GE. Aggelos Economopoulos ported it from FreeBSD. Check his post for notes and credits for the people who helped out.
Michael Neumann has removed the PRISON_ROOT flag, and has changed jail(8) code to use only prison_priv_check() to check for allowed operations. This won’t mean anything from a user standpoint, but it does make programming easier.
pipe(2) is now MPSAFE, meaning it can take advantage of multiple processors without the Giant Lock. Matthew Dillon published some before-and-after stats in his commit.
The kernel option PCI_MAP_FIXUP has been removed as of July 11th; if you’re upgrading past that point, make sure to remove that option.
The in-progress code for the Summer of Code project ‘DragonFly on AMD64’ has been imported; you can now build for SMP on AMD64, and complete a installworld/buildworld, natively. Modules don’t (yet) compile…
Virtual kernels are now SMP by default on DragonFly, even if you don’t have multiple processors/cores.
Peter Avalos has updated libpcap to version 1.0.0 and tcpdump to 4.0.0. (tcpdump site) I’d guarantee that having at least a passing familiarity with tcpdump will eventually, someday, solve an otherwise intractable problem for you.
Threading libraries libc_r and libthread_xu have been synchronized by Hasso Tepper; this shouldn’t cause noticeable issues. The potential issues he mentions for pkgsrc appear fixed, as I haven’t had any significant trouble (from that, at least) during bulk builds.
Sascha Wildner has made it possible to include “other” compilers (meaning not GCC) in DragonFly’s build system. His post has additional details.
The hammer command now has an ‘info’ option, which gives a great deal of information on your Hammer drives, thanks to Antonio Huete Jimenez. (Committed)
Matthew Dillon fixed a problem with AHCI on July 2nd. If you are running AHCI from before that date with a port multiplier, you may want to update. Further tests have completed without issues.
Alexander Polakov has put together an update of PCI bus and ACPI interrupt handling code taken mostly from FreeBSD, and ported it to DragonFly. Please try it out – if you previously had booting issues with DragonFly, this may have cured them.
