Pierre Abbat noticed that bc(1)‘s usage of GNU readline something that wasn’t GNU readline made it harder to use; Sascha Wildner changed it to use libedit. Pierre’s other complaint, that BSD man page output stays on-screen when completed, is a positive feature. Linux systems that clear man page output enrage me, because I expect to be able to take advantage of my scroll buffer.
John Marino has added a ‘gcc47’ compiler ccvar, so you can build world and kernel with it. ‘It’ is actually gcc-aux, since it seems to work better than the basic (“vanilla”?) gcc47. You also get Ada support, though that wasn’t the driving reason to pick it. This is brand new so don’t try it unless you’re ready to discover issues.
Is there any other BSD able to use gcc 4.7 for world/kernel? Even 4.6? Most of the attention has been on clang.
Nuno Antunes is still working on that netgraph upgrade. Among other changes, ng_tty has been added. What’s it do? Something with ppp, I think.
Based on a suggestion from Venkatesh Srinivas, tmpfs now uses a red-black tree for directory lookups, and is also now faster. Credit goes to Johannes Hofmann for doing the testing.
Sascha Wildner has synced find(1) with what’s in FreeBSD, which means there’s a lot more options available – see the commit for details. Many of them are for GNU compatibility, and I’m sure I’ll forget them all. I seem to have issues remembering how to use find(1) successfully.
Sascha Wildner has made it easier to use alternative syntax checking systems as a “lint” make target in DragonFly. His usage of coccinelle, as one of these alternatives, has already found many bugs – just today, for instance.
Is “alternative syntax checking systems” the right phrase for this? I don’t know. “Correctness checker”? My phrases all sound like something you’d read on a government form.
Reading this HAMMER2 commit carefully shows some future plans: remote cluster control, and the ability to mount nonlocal HAMMER2 volumes. A reminder: those are future plans, not what you can do now.
The i386-only doscmd(1) is gone from DragonFly. I don’t think I ever used it, as other emulators/systems are so prevalent and complete.
Sepherosa Ziehau has added netblast, a tool originally from FreeBSD that, if I’m reading the commit right, flings packets of a given size at an IP/port of your choosing, for as long as you want.
It’s possible to accidentally truncate your password when using DES encryption and 0x80 in UTF-8 encoding. It’s fixed.
Sepherosa Ziehau has made some changes to SIOCGIFDATA, so if you are using DragonFly-master and pf, you will need a full rebuild. Also pftop, if you use it.
Thanks to Magliano Andrea Andrea Magliano, a new version of ACPI has been added to DragonFly, acpica-unix 20110527.
If you are running bleeding-edge DragonFly, libpthread was broken for a short period. If you built anything in the last … 12 hours? You may want to rebuild it. If that doesn’t describe you, it’s a nonevent.
It’s funny that I’m reporting a short-term break in bleeding-edge operating system code as any sort of surprise. It shows something about how stable DragonFly-master is most of the time.
Sepherosa Ziehau has been making various updates that conform to standards lately, including “RFC4653 Non-Congestion Robustness (NCR)” and “RFC3517bis“. I’m not familiar with what they do, but you can follow the links and read the RFCs if you are curious.
(Not sure if I got that 3517 one correct…)
Apparently Apache 2.4 has a bug that will cause network stalls when sending data that doesn’t line up with segment size. Sepherosa Ziehau has put in a workaround for the issue. Alternately, you can use www/apache22.
John Marino has updated libncurses, libedit, gdb, libgmp, and zlib. The release notes are helpfully contained within each commit. If that wasn’t enough, he’s also added terminfo, a future replacement for termcap, if I understand correctly.
Peter Avalos has updated OpenSSL in two different places:. The 3.0 release now has OpenSSL 1.0.0j, which fixes several security issues (see link for CVE IDs). DragonFly 3.1 now has OpenSSL 1.0.1c. As for a changelog… this, maybe?
You’d think everything that could be done with grep has already been done, but no: grep, which is an externally-produced program, has been updated in DragonFly to version 2.12 by John Marino.
