In principle, yes, you should be able to use the INDEX to extract only a port and its dependencies rather than downloading the whole ports tree. Remember you will need the *build* dependencies as well. Not to mention everything under /usr/ports/Mk and quite probably everything with a name in CAPS under /usr/ports. However, be aware that you will be confined to using just the /default/ port options: if you try and customize things, you'll change the dependency graph and the standard INDEX won't match any more. On the whole though, most people don't make any more than a cursory attempt to implement something like this. The amount of hassle just isn't worth it. The ports tree is not that huge in the grand scheme of things -- without the distfiles it takes up about half a GB, and about 140,000 files or directories. That's comparable to what some of the larger ports (eg. OpenOffice: 1.9GB and 76,000 files once extracted) use for their sources alone. If you're running out of inodes that suggests you didn't create the file system with the standard 4k per inode ratio.

And yet, there's an equally valid argument that the most important

warn x = $x, y = $y, z = $z\n
if $debug;
... the most important part is that it's printing something to stderr,
and what's being printed. It's only minor that it's only when
debugging, and luckily Perl lets us relegate that to the tail end of
the statement.
Now, if you argue oh, the most important thing there is 'if debug',
then fine, you'd write that as:
if ($debug) { warn ... }
And I'd be fine with that. But I tend to see that layout as a lot of
noise just to add a minor conditional. Or you could speak Perl
with a Shell accent, and say
$debug and warn ...;
Fine, that also works, and some part of your audience will hate you,
and another part will be totally cool with it.
But this *is* the reason There's More Than One Way To Do It in Perl.
You can write Perl that most naturally expresses what you believe
is important in the code.

When I still did not pick up the change, I updated from a cvs repository. My question is how are the mirrors updated (cvsup2 specifically I guess). In general is using csup and cvs equivalent processes for non developers?. Your message doesn't really make sense to me; I suspect you're confusing cvs with cvsup, but I'm not sure. cvsup and csup are different implementations of the same functionality, and connect to the same servers, so they really won't be different (they are, in fact, interchangeable). Anonymous CVS access is not widely used, and is really recommended only for experts. Different hubs update on different schedules, but official ones are recommended to update hourly. Development actually occurs in the subversion (a.k.a. svn) repository these days, from which it is automatically exported to the cvs repository (which is also the source for cvsup servers data). I'm not aware of non-developer direct access to the svn tree, nor do I know much about how the subversion data gets merged to cvs. I've used different cvsup servers over the years, but I've rarely noticed an update taking more than an hour after it hit cvsweb.

thanks for your url as well and the others to posted. but it seems
like overkill since i dont need any explicit option or argument. i
just need the script to tell me whether i have an arg or not.
following is something i've kept in one of my junk drawers from when i
was learning to write bourne sscripts. it uses the $[token] syntax
that determines whether there are Any args on the cmdline. if not,
the script prints a message and exits.
#!/bin/sh
if [ $# -eq 0 ]
then
echo No args; need filename.
else
echo $1
fi
After a couple hours experimentation, the following does the same for my
perl scripts:
#!/usr/bin/perl
$argc = @ARGV;
if (! $argc ) {
printf(No args; need filename.\n);
}
else {
printf(%s\n, @ARGV);
}
Yes, that's very close to the sh(1) version. Perl's behavior in this
case is described in the 'perlvar' manpage:
@ARGV The array @ARGV contains the command-line arguments intended
for the script. $#ARGV is generally the number of
arguments minus one, because $ARGV[0] is the first
argument, not the program's command name itself. See $0
for the command name.
In other words, when @ARGV appears in scalar context it yields the
'size' of the @ARGV array, e.g.:
% cat foo.pl
printf(%d .. args = [%s]\n, int(@ARGV), join(', ', (@ARGV)));
% perl foo.pl
0 .. args = []
% perl foo.pl 1
1 .. args = [1]
% perl foo.pl 1 2 3
3 .. args = [1, 2, 3]
So when int(@ARGV) is zero you know that there are no arguments at all.
This means you can write your sh version like this in Perl:
#!/usr/bin/perl
if (int(@ARGV) == 0) {
die No args; at least one filename expected;
}
printf(%s\n, join(' ', (@ARGV)));
This is good enough as a command-line handling trick for really simple
scripts, but you should probably have a look at the Getopt::Std and the
Getopt::Long modules for longer scripts. Using them will make your
option parsing code much cleaner and easier to change in the future.

I have a similar problem with a D-Link NAS I use for rsnapshot, however my NAS does not come up after a power outage _period_. The solution I use is to 'noauto' the nfs mount to prevent the stall until I can boot the NAS. I then created /mountpoint/NO, which the existence of the 'NO' file is checked before rsnapshot via cron telling rsnapshot if it is okay to backup to the mountpoint. The result is that my machine will continue to boot after a power failure, and the filesystem will not get clobbered by recursive backups.

Re: csup vs cvs

When I still did not pick up the change, I updated from a cvs repository. My question is how are the mirrors updated (cvsup2 specifically I guess). In general is using csup and cvs equivalent processes for non developers?. Your message doesn't really make sense to me; I suspect you're confusing cvs with cvsup, but I'm not sure. cvsup and csup are different implementations of the same functionality, and connect to the same servers, so they really won't be different (they are, in fact, interchangeable). Anonymous CVS access is not widely used, and is really recommended only for experts. Different hubs update on different schedules, but official ones are recommended to update hourly. First thank you for responding to an obviously badly worded question. I think my understanding exceeds my ability to explain my question. So I will be very specific about what I wanted. A change was MFC'd to the xorg intel driver to include support for the new chipsets. I took the fact that I could see the change on the web: Date: Sun Apr 4 15:37:47 2010 New Revision: 206164 URL: http://svn.freebsd.org/changeset/base/206164 Log: MFC r205096, r205102 Add AGP support for Intel Pineview and Ironlake chipsets. to mean that it would be propogated out to my favored csup server in due course. The change was not on cvsup2.FreeBSD.org by 2AM Monday, so I got a source tree from a cvs repository my unix guru runs and updated using that. I used his because I host it. What I attempted to ask is (1) how are the mirrors updated; and (2), is there a particular lag time where the latest changes would have to be there? This is not normally an issue for me but I have a laptop that will not run X w/o this change. I normally do not use cvs because, I am not a developer and my 'learning new things bucket' is pretty full. Hence my [however badly worded] question.

RW Imperative languages have a natural order of decision followed by
RW action, and code is most easily readable if the syntax doesn't try to

And yet, there's an equally valid argument that the most important
thing should stand out the most. In that sense, in the Perl statement:
warn x = $x, y = $y, z = $z\n
if $debug;
... the most important part is that it's printing something to stderr,
and what's being printed. It's only minor that it's only when
debugging, and luckily Perl lets us relegate that to the tail end of
the statement.
Now, if you argue oh, the most important thing there is 'if debug',
then fine, you'd write that as:
if ($debug) { warn ... }
And I'd be fine with that.
Let's suppose you want to display one message if debugging is enabled, and a
shorter message if it is not. Adding an else clause to an if statement is a
natural change and the result remains highly readable. Can one even use this
postfix test syntax with an else, or would you have to re-write the first
version entirely?
As far as I am concerned, the first version resembles exception handling, ie:
try:
something
except Error1:
handle error
...and should be reserved for situations where the statement is expected to run
normally. If it is reasonable that the test might fail more often than in
unusual circumstances, then I'd really prefer to put the test first.
If you don't like all this freedom, there's always Python. :)
Yes, Perl lets you innovate a remarkable number of ways of solving the same
problem using syntax that varies from clean and maintainable to constructs
which even the original author won't understand without effort a few months
later. It seems to be uncommon for one to write unreadable Python code; I'm
not sure additional freedom to write obfuscated code would be as beneficial as
one may assume

RE: Preventing Bad SMB Mount From Stalling A Boot
I mount my SMB shares from /etc/fstab on a FBSD 8.x production machine like this: //USER at WINSERVER/SHARE /mountpointsmbfs rw 0 0 The problem is that after an outage, WINSERVER doesn't come up before the FBSD machine. So, the FBSD machine tries to boot and then hangs permanently because it cannot get the SMB share points mounted. This recently happened after a catastrophic power outage that cooked the share info on WINSERVER. Even after it came up, it was no longer serving the proper shares and the FBSD machine could never find the SMB shares and thus hung permanently. The SMB mounts are not essential for systems operations. Is there a way to tell the FBSD to try and mount SMB, but keep going and complete the boot if it cannot? A bit of an ugly hack, but have you considered attempting to mount the share via an automatic script after the system has finished booting? - Sincerely, Dan Naumov ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Interrupt ptr 12h?
Hello list, sometimes my system freezes, and I cannot figure out why. What I do know is that everytime I try to build openoffice, it freezes during the build process. Last time my system froze, the kernel spat out the following message: kerneltrap with interrupt ptr 12h disabled.

Thanks, -Tom___ I used them for 2 jail based VPS Iota plans for a few months in 2008 before deciding to get dedicated hosting elsewhere. I believe they use full virtual machines via Xen now instead of jails, so my input on their system administration is of little use to you. There were a few kerfuffles, although customer service did seem very responsive. There was downtime due to a RAID controller failure, and my account was credited for it. Since system administration is still on you though, so you might also consider a dedicated server elsewhere if you can push the budget up to at least $50/mo.

And most of them are obscure for good reasons. Just because a a syntax fits into a classification scheme doesn't make it a good idea. The fact something is popular doesn't mean it's a good idea. Shall we trade more trite sniping, or would you like to say something more substantive? In no way, and at no time, did I imply that using unless like an infix operator is a good idea just because it fits with a given syntax classification. Natural languages are mostly driven by spoken usage, in which people firm-up half-formed ideas as they speak - this is not a good model for programming languages. If you are hacking out a quick and dirty script it may be convenient to type the decision after the action, but it don't I think it promotes good quality software. This sounds exactly like the complaints Pythonistas use to explain why they have a deep hatred of Perl. If that's how you feel, I'd prefer you stop trying to tell me how Perl should work, and just use something else. Imperative languages have a natural order of decision followed by action, and code is most easily readable if the syntax doesn't try to subvert that. . . . except when the natural order of decision varies significantly, such as when comparing functions with operators. It gets even more confusing when both functions and operators are actually methods in object oriented languages with an imperative design, because suddenly the difference between a function and an operator becomes purely arbitrary. There's nothing about arbitrariness that suggests a natural order. It's kind of odd you rail against natural language then talk about imperative languages having a natural order -- which is, presumably, based on the expectations of people who have been conditioned to think that way by their use of natural language. Frankly, if everybody just stuck to a purely natural order of decision approach to imperative language design, we would never even have developed structured programming. -- Chad Perrin [ original content licensed OWL: http://owl.apotheon.org ] pgpEUjI65NlvI.pgp Description: PGP signature

What incidentally does /var get populated with? Our image has a custom directory under /var but this did not show up in the MFS versions of this directory. I can get around this but I wonder what else might not be included? I found something else that's missing--/var/db/pkg is empty. It looks like what the auto-var process does is a construct basic directory structure but no data. Is there a solution to this?
