Images are available for download at various mirrors, too. If you’ve recently upgraded to 5.4, it’s the normal build process. There’s a brand new complete build of all packages uploaded, too, so plan on a ‘pkg update’.
This may never ever matter if you manage to avoid fdisk your whole life. But if you don’t pull that off, here’s the reminder: label your DragonFly slices with 108.
(Yes, I do in fact have a backlog of two months with DragonFly material. It’s been that constant.)
Matthew Dillon’s committed some performance work for HAMMER2, dealing with write-clustering. I don’t have statistics to note, so here’s the commit message.
This is the commit I should have linked to yesterday, and was reminded by an anonymous commenter: git: sys/vfs/fuse: Add initial FUSE support. It’s not complete, and so isn’t built by default; check the commit for details.
time_t in DragonFly is now 48-bit. This won’t affect anything you do day-to-day, probably, but it’s neat to see the 9 million year timeframe.
It’s possible to have data corrupted on a HAMMER2 volume during a specific combination of a bulkfree operation and a lot of writing to disk. Matthew Dillon has a potential fix already. As he announced, it’s scheduled to go into 5.4 this weekend. It’s a rare bug, but if you want to check for it, look for CHECK FAIL entries in /var/log/messages.
And because every cloud has a silver lining: some not-yet-quantified performance improvements.
There’s some code changes for callout, where the actual lines of code that trigger it are stored in the callout structure. It’s a little thing, but it’s a big thing if you need it.
Thanks to Aaron LI, you can now (actually, since December) run ifconfig without involuntarily loading associated kernel modules, with the -n option. See his commit message for an example.
I’m finally cleaning out some things I never got to post when new: last October, the DragonFly installer gained the ability to ask for terminal type, when used over a serial cable. Thanks to Diederik de Groot for that one.
(A rare combination… but when you need it, you won’t have an alternative.)
A little thing: Matthew Dillon has made changes to vm_page_list_find2() which should improve performance in low-memory situations, though how much I don’t know. Mentioning it, cause every little bit helps – for knowledge and speed.
Because someone decided years and years ago that the CAM structures should be passed through to userland, smartctl, camcontrol, cdrecord, and some other tools will be broken in DragonFly-master for a few days. If you are on -stable (5.4) this won’t affect you.
