DragonFly pkgsrc repo is frozen

The pkgsrc repository in git for DragonFly is currently frozen.  This is because many people have switched over to dports, and also because it’s a lot of work to keep it functional.  If you do want to pull newer pkgsrc material, use cvs and grab it from a NetBSD server.

As the message notes, don’t go switching to DragonFly-current right now, cause there’s a lot of new material in there and it may not be quite safe.  (There’s an ABI change that will require all new builds of your ports, for instance.)

OpenZFS announced

ZFS was originally created at Sun and open sourced.  Sun was absorbed by Oracle and stopped being open (or even really existing), so ZFS was taken up by several separate groups – FreeBSD and Illumos being two examples.  OpenZFS has been announced, in part to provide common reference for other platforms that might implement it and probably to avoid capability fragmentation.  It’s certainly a good idea.

(If I have my history wrong, please correct me.)

Moving dports to gcc 4.7

DragonFly has two included compilers – GCC 4.4, and GCC 4.7.  Traditionally, we switch from one compiler to the other as default, and then replace the old one with a newer release, and so on.

Until recently, dports built almost exclusively using GCC 4.4.  John Marino’s switching to GCC 4.7, for a variety of reasons he lists in a recent post to users@.  An interesting point that he raises: GCC 4.4 won’t necessarily be replaced with a newer GCC, but perhaps clang?

TCP improvements

Sepherosa Ziehau has made a number of improvements to TCP in DragonFly – specifically, nonblocking and blocking connect(2) performance.  See each of his commits for statistics on how much this has reduced processor use under high load.  He has also written up an extensive description of how all this TCP stuff works in DragonFly.

In similar news, he has a nginx patch that delivers a significant performance increase.  It may go into nginx itself.

Mailing list archives update note

The mailing list archives for DragonFly (lists.dragonflybsd.org) have been moved to new hardware.  (Yay!)  The patch that actually shows date in the listings needs to reapplied, cause Mailman is somewhat stale.  (Boo!)  I applied the patch and I’m regenerating all the archives now.  (Yay!)  There’s some garbled messages in the archives that cause a bunch of “no subject” partial messages to be dumped at the end.  (Boo!)  I’ll manually fix them if I can, someday.  (Yay?)
