Does it work better if you compile without optimization? I think I've
seen this one before....

Subject: BIZARRE: killing window kills bg perl process
Message-Id: <6qd7vu$1tr@news1.panix.com>
I have a perl script that runs fine in the background (e.g., "foo &")
as long as its parent shell is up, but dies immediately if one kills
the shell, just as if it were a foreground process. I've never seen
this behavior before, nor have ben able to reproduce it with simpler
test scripts.
The OS is IRIX6.2 and the perl version is 5.004_4.
Does anybody have any idea of what could be causing this behavior? Is
there anyway to catch perl's last words as it's going down (i.e. when
the shell is killed)?
Thanks,
K.

You've just illustrated one of my least favorite things about
clp.moderated -- it raised from 2 to 3 the clp*m* ambiguity count. Even
clp.mod now has 2 possible meanings. Hey, perhaps we should rename
clp.announce to clp.messages...

Yeah, I think that's most of it. :) If one looks at the moderated groups
for other languages, they tend to be a good bit lower in volume than the
unmoderated groups.
'sides, it takes at least three to six months for *any* new newsgroup,
regardless of interest, to really hit its stride.

Your explanation certainly helped me. Before I had to stop and go
to a meeting, I was researching this identical point at work,
having forgotten which /[ms] did which. I didn't get as far as
Friedl, but did check the two I mentioned above and found
no help there.

Yes, but you're wrong. None of those hierarchies with the possible
exception of relcom.* are regional hierarchies. They're all world-wide
*language* hierarchies.

By and large I agree with you, and I don't mind the occasional posting in
another language. I'm just trying to make the point that this group (and
clpa) are not *intended* to be the be-all and end-all of Perl newsgroups
and that there are other groups out there for other languages and a
general expectation that the vast majority of traffic in comp.* is going
to be in English.
> Well, of the 7 groups you mentioned, PSInet doesn't carry 4 of them.
Hadn't you previously mentioned that PSI also doesn't carry
comp.lang.perl.moderated? I'm somewhat unimpressed by this news provider.

In the first script, you are appending data onto a single value ($q{"1"}
.= ...). In order for perl to tell Berkeley DB what to store, it reads
the current value into memory, adds the text onto the end, and then it is
stored back in the database. Each instance requires the entire string to
be brought into memory in order for the append to occur.
In your second script, a new key is used for each value ($q{"$x"} = ...),
which means that perl only needs to keep the single, current value in
memory. All other instances are written to the database and never re-read
or kept in memory.

Indeed. Or if the first right paren were the double right paren I thought I
typed.
Teach me to run the code before posting it. Or to cut and paste from actual
working code - I mean, I do have actual working code using that, with matching
parens and everything!
It's also missing the necessary
use Socket;
so AF_INET is in fact undefined. So it doesn't do much more than compile...
Someone put better code for this elsewhere in this thread anyway,using
inet_aton instead of that split and pack.
I stand humbled.

Don't! The Net::SMTP module already does this although it suffers
from having to reinvent the spooling wheel if the SMTP server is down.
Stick with sendmail or qmail.

Sure. DejaNews cannot claim to have a complete archive. They would
probably make more money if they could.
Chris, were you around when DejaNews started? Did you follow the
discussions that led to the creation of X-No-Archive in the first place?
I don't believe you realize how *many* people were upset and just *how*
angry they were.

It is generally considered to be good manners, if you are maintaining an
archive of any sort, to honor the X-No-Archive header. Something along
those lines is likely to be put into the next revision of the news
standards, after which point if you were maintaining a publically
accessible archive and did not honor the header, and this caused problems
for someone, it's quite likely you could be sued and would lose.

You seem to be under the impression that I think DejaNews is bad. That's
not what I'm saying. I'm saying that the semantics of Usenet do not
include archiving for indefinite periods of time, and that when a service
is created that changes those semantics, having an opt-out mechanism is
honestly the least that one could expect.

Well, I like dejanews a lot, but got somewhat confused.
I don't believe that if I decided to not let archive my posts that
they would loose money, nor do they directly gain money if I post
through them as long as they offer access to the archives and a
mailbox at no cost and their archives remain as compre-
hensive as possible.
If advertisers pay them a lot and they use it to provide something
useful, that is fine with me, too.
I thought I missed any other aspect of how they make profit when
I read Russ Allbery's post.

Your use of quote marks is odd. But maybe you mean that you can read text
in from a file and output it. Okay.

Nope, you lost me again. Buttons aren't variables. But (in any case) it's
all just text to perl. Just output the right text, and you'll be fine. If
you're not sure what text to output, though, the docs, FAQs, and
newsgroups about HTML and related issues might be what you need. If you
want to use a Perl module to process the input and produce the output,
there are several available on CPAN. Hope this helps!

If there's a module which does what you want, it should be listed in
the module list on CPAN. If you don't find one to your liking, you're
welcome and encouraged to submit one! :-) Hope this helps!

(JS?) Every package is visible everywhere. There are no invisible
packages. But you don't need to list every package variable in @EXPORT or
@EXPORT_OK, of course.
Hope this helps!

(Did you leave off a close paren?) Even when your script is "just an

the return value after opening a file. Hope this helps!

It sounds as if you're trying to get a browser to do something. The docs,
FAQs, and newsgroups about browsers should be able to help you with that.
Good luck!

Subject: Retrieving the value of a matched pattern
Message-Id: <jpatton-0608981637540001@athens.dazel.com>
When matching a pattern, where you know the format of the pattern but not
the actual values therin, what is the best way to retrieve that value??
Example: You have a program that reads in text that contains a URL
somewhere within. You want to determine the exact URL so that you can
create a valid HREF tag around the text. Sure you can match the http://
at the beginning of the string and the .html at the end, but how do you
determine the value of the text in between?
This seems to be a recurring problem for me. I always have to come up
with some bizzarre hack to find the unknown value. There has got to be a
sane way to do this - despite the lack of attention to the problem by the
perl faq and all of the perl books that I own.

Read the perlre manpage. Search for `backref'.

I would. What's hapening is that ld.so won't rescan the process's environment.
It's already done it once, well before the interpreter ever gets started.

That (or a variant thereof) should work. It will set LD_LIBRARY_PATH
prior to ld.so's first invocation for the perl process. Or perhaps the DBD
modules can be compiled with LD_RUN_PATH set, or symlink the required
library in /usr/lib.

Is there any particular reason why you have to use Novell's Perl? It
sounds like a rather non-functional version if Socket won't work right.

Well then the answer to the original question (which was, "What would be an
appropriate lesson plan for teaching Perl") depends critically on the code
that you want them to understand, doesn't it?
Obviously, someone who truly wants to be a functional Perl programmer needs to
know both references and regular expressions.
But short of posting your code here, only you can decide what people need to
know to read your code. If you write stuff heavy on complex data structures,
then you need to teach them references. If you do lots of complicated regular
expressions, then you'll probably need to teach them about those. If you have
both, then you *have* to teach them both, it seems to me.
(BTW, the comment that teaching people to access the documentation is a good
one; there's so much clearly written documentation that even a few minutes on
how to access it can drastically lighten your teaching load.)

I'm currently immersing myself in a zen-like state to fully and completely

Are you saying that you don't want to change the program but you just want
the webserver to ignore the warnings? Maybe the docs, FAQs, and newsgroups
about your webserver can tell you how to configure it to ignore warnings -
or they can tell you why you shouldn't ignore warnings! :-)

moderated one.
If you have opinions on this, send them to
perl-users-request@ruby.oce.orst.edu.
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
