Re: Benchmark: NetBSD 2.0 beats FreeBSD 5.3
Am Freitag, 7. Januar 2005 09:58 schrieb Gerald Heinig: Hi Robert, the benchmark you cited is for uniprocessor systems only. It says nothing about multiprocessor performance, which is what FreeBSD is aiming for. It's comparing apples with oranges. No, many users, me included, only run FreeBSD on UP systems. Do I have to switch to (Net|Open|DragonFly)BSD because FreeBSD is now only targeted to MP? I do not think so, and thats why this benchmark does compare apples with apples, but these are microbenchmarks, and more complex tasks may show completely different results. I am also missing results with Linux (and other BSD's), which may better show our (FreeBSD's) position.

At times I've asked Doug about some kind of pattern-support in
~/.mergemasterrc, where the user could specify filename-patterns
of files where they want the default action to be install
instead of leave for later. There are pros and cons with that
idea, but that's what I was thinking of for the directories you
describe.
Doug has suggested that people could maybe do things with the
MM_PRE_COMPARE_SCRIPT, for special processing like this.
I have a small patch for pattern-support in ~/.mergemasterrc and
already sent my ideas to Doug, but he said It could/should
be done with MM_PRE_COMPARE_SCRIPT to me.

I don't know how find-sb compares to the program you're talking about, but they sound kind of similar. Scan_ffs can print the lost disklabel for use with disklabel(8). Find-sb, that version from cvs, seems only to print info about the superblocks of each file system and you have to rebuild the lost disklabel for your self. I was on the search for a simple tool for everybody, and found scan_ffs several months ago in the OpenBSD distribution (so it seems find-sb was like reinventing the wheel) and Robert Watson suggested in a posting december last year to adopt scan_ffs for UFS2. IMHO we should reuse a already written program with existing man pages, so we have the same sounding tools for the same tasks. I don't know what find-sb could do with your patches applied.

scan_ffs for UFS2
Hello!
I am trying to learn scan_ffs (original from OpenBSD, ported to FreeBSD
by Robert Watson) about UFS2 on 5-CURRENT, but it will not find the
Superblock and I dont understand exactly both for loops, especially
that 512 byte increment.
Scan_ffs is a system tool from OpenBSD to recover erased disklabels
from your hard drive.
Thanks for your input.

Ok, now scan_ffs can detect a UFS2 filesystem, but scan_ffs does
not calculate the correct offset for the disklabel. Further I do
not unterstand the smart feature of scan_ffs fully at the moment.
Where to I find CPG in an UFS2 superblock? How can I detect, if
scan_ffs should display fs_old_cpg or the new cpg value. Which
fields hold the new cpg value in the superblock?

You can review my code on http://www.ranner.jawa.at/freebsd.php. In between I have modfied 5.0 restore to use setattr(). Because of the new UFS2 birth time attribute, I have to call utimes() before setattr(). Struct stat has no member for the file birth time. Any suggestions to improve setattr() in respect of the new UFS2. The systime of 5.0 restore decreases around 9%. from man utimes For filesystems that support file birth (creation) times (such as UFS2) the birth time will be set to the value of the second element if the second element is older than the currently set birth time. To set both a birth time and a modification time, two calls are required; the first to set the birth time and the second to set the (presumably newer) modification time. Ideally a new system call will be added that allows the setting of all three times at once. I'm also willing to implement the proposed new syscall, any suggestions for name and type of arguments (probably an array of struct timespec). The kernel code already supports an array with all three time stamps.
