Subject: "cloning" tied hashes
Message-Id: <Pine.A41.4.02.9902111043580.25262-100000@ginger.libs.uga.edu>
I have implemented a TIEHASH class the details of which may or may not be
important. I am tie'ing %sgmlrecs1 in such a way that it interfaces an
8000+ record file. I am tie'ing %sgmlrecs2 (using the same class) in such
a way that it creates a new file.
Using the first block of code, from 2 to 6 of the 8000+ keys generate
calls to the STORE method in which the third parameter (the value) is
undefined. The second block of code does not do this. Is there a
known problem doing block 1) with two tied hashes?
1) %sgmlrecs2 = %sgmlrecs1;
2) while( my( $key, $val ) = each %sgmlrecs1 ) {
$sgmlrecs2{ $key } = $val;
}
Thanks,

Can anyone tell me if a GDBM hash file module (or equivalent) exists for
ActiveState PERL on the Windows platform?
SDBM (and others) limit the hash value to 1000 characters. GDBM on UNIX
allows much larger values. I want to use a hash file that allows large
values on the windows platform.
Thanks.

Even if they do span a month boundary, you can compare weekday of both to
accomplish the same.

-OR-
your headers could be wrong. If the browser does not detect the correct
first couple of lines of output, it assumes it is some kind of file to be
downloaded. for save this program as blah.pl in your cgi-bin directory:
print "Content-type: text/html\n\n";
print "<HTML><HEAD><TITLE></TITLE></HEAD><BODY>\n";

and run it by using something like: http://localhost/cgi-bin/blah.pl

OK, I've done that, and it looks like I have to send:
"Authorization: credentials" after the request. But I'm not sure of the
syntax. Currently the script sends:
GET url HTTP/1.0
So I modified it to send:
Authorization: user:passwd
after the GET line; I've tried every variation I could think of, but I
always get back "HTTP/1.0 401 Unauthorized"
What is the syntax for that?

Yes, I know about that, but they don't have libwww installed, and I don't
want to get into that - I just want to add the one needed line to this
script and move on.

I've read furthur, and I now see that I should send:
Authorization: Basic user:passwd
where the user:passwd portion is coverted to base64.

All good advice if we were talking about a DIF file.
I think we're not.
The wotsit site is indeed a good resources, but it doesn't seem to know LDIF.
Perhaps that's because LDIF is pretty new, and not yet standardized.
As noted elsewhere in this thread, LDIF is a data interchange format used by
LDAP, a directory access protocol derived from the X.500 ISO standard. LDIF
will someday be defined by an IETF standard (aka RFC). Right now, it's in
draft and should be regarded as a "work in progress".
The latest Internet draft on LDIF can be found at
http://search.ietf.org/internet-drafts/draft-good-ldap-ldif-02.txt
and was just put there on Feb 1.
Further info on LDAP (and probably LDIF as well) is available at
http://www.umich.edu/~dirsvcs/ldap.
But we digress... ;-)

I think I see what you're trying to do. Perhaps grep would serve you
better.
@test = grep { ! deletion criteria } @test;

Don't do it with array slices. Use 'splice'. There was a thread here
about that two weeks ago. Read it!

Hi
This seems simple but I am having problems with it. I need to determine if
there is any binary info within a given string. It seems like pack and/or
unpack are needed but I can't figure out how to use them. Or is it
something else entirely. The only way I can figure it out now is to check
the string against every Character I DO want in the string (ASCII
friendly) but that is very messy.
All suggestions are welcome. I know there must be a simple way to do this.
Thanks very much to all.

Subject: Perl 5.002 compile on NT?
Message-Id: <36C30680.E6D72E68@dev.tivoli.com>
Hi,
I really like Perl and have used it for years. I compiled it on my Sun
box with basically 4 commands per module. A 4th grader could do it after
glancing at the instructions.
On my NT box, I currently use ActiveState Perl due to severs compiling
difficulties on NT, but I want to compile it from source like the real
hackers do. I want to add many modules, some of which I understand are
not binarily compatible with ActiveState.
I have downloaded the latest, stable Perl (p500502) and have vc++ 5.0
and am using the "cmd" shell as recommended in the readme.win32. I have
edited the win32/makefile.mk as follows (and checked the accuracy of
CCHOME):

I immediately get this error.

This is very easy. If
perl --version
does not work, you have a very old release.

P.S. In fact this gives *some* answer even with 4.036.

I hope 5.005_55 will contain my patch which will do shell-less 2>&1
(at least on EMX/RSX platforms). I'm also preparing a patch which
does a conservative processing of "" and '' (and simplest
backslash-escapes - I'm afraid that different sh-shells may have
different rules).
I see no reason why these patches cannot be combined to cover
redirections too.

Subject: Running script locally in browser
Message-Id: <79u2cr$b2o$1@msunews.cl.msu.edu>
I have successfully written some Perl scripts and tested them on a remote server and from the command line. I am unable to view them in my browser. All I get is the script in text form as if I asked to see the source. I seen another entry which suggested mime type problem. I don't see where this would cause a problem. I am using Linux kernel 2.0.36 and I am somewhat new to it. I am familiar with the basics of the OS, but anything more than the basics may need some explanation. I am using Perl 5.004
. I should extrapolate and say that I cannot view them via my browser locally, but I can browse to them on a remote server and run them fine. Please reply via e-mail to swanbria@pilot.msu.edu.
Thank you in advance for your help, it is GREATLY appreciated.

There are two distinct perl builtins called select(). You want the
four-argument version, which calls the select(2) system call.
perldoc -f select

But you don't use many Microsloth products do you? :-)

Well, after 6 months, here's the answer to the quiz: what do we do about
comp.lang.perl.moderated. Answer: nothing.
]From: Russ Allbery <rra@stanford.edu>
]Date: 21 Sep 1998 19:53:43 -0700
]Subject: comp.lang.perl.moderated available via e-mail
]
]It is possible to subscribe to comp.lang.perl.moderated as a mailing list.
]To do so, send mail to majordomo@eyrie.org with "subscribe clpm" in the
]body. Majordomo will then send you instructions on how to confirm your
]subscription. This is provided as a general service for those people who
]cannot receive the newsgroup for whatever reason or who just prefer to
]receive messages via e-mail.
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.
