Thanks for reply. I always RTFM! I should have mentioned, no proxy,
no firewall, no errors on install, a real 'standard' W95 setup.
I was hoping someone would say activestate is having a problem today,
try later or give me some additional trouble shoot info. Seems it

Message-Id: <01be4d33$4f47f7e0$6701a8c0@dan>
In a multiuser environment you can create a lock file when you want to
avoid simultaneous update of a file and check that the lock file does not
exist before you open the file you want to update.
But then if your program crash the lock file is still there.
Is it instead possible to directly see if the file you are opening is
already opened by another user?

PS. Can someone recomend reading of locking techniques in multiuser

I have several cgi (perl) log file programs (some that I've
written, some that others have written). The common thread to all
of them is that they all seem to "double log" things occasionally.
Anyone know why? Does it have to do with the flock command (to
prevent file corruption) or possibly the way that browsers
actually retrieve the document? Any workarounds?

Try loading the computer names into a hashtable instead of an array, using
the computer names as keys. Then if you want to check if a computer
exists, just check for the existence of the appropriate hash key.

Ouch, bundling. That's the word I have been looking for.

Works for me now.
See:
|#!/usr/bin/perl -w
|
|use strict;
|use Getopt::Long;
|Getopt::Long::config('bundling');
|
|my $force = 0;
|my $stateFile = $STATEFILE;
|my $verbose = 0;
|my $debug = 0;
|
|GetOptions( "debug|d" => \$debug,
| "verbose|v:i" => sub {
| my ($dummy,$value)=@_;
| $verbose += $value-1 if $value;
| $verbose++;
| },
| "force|f" => \$force,
| "state|s=s" => \$stateFile ) or usage();
|
|print "\@ARGV: @ARGV\n";
|print "\$verbose == $verbose\n";
|print "\$force == $force\n";
|print "\$stateFile == $stateFile\n";
|print "\$debug == $debug\n";
This seems to work like a charm. Hints how to get rid of the local
variables in the code reference for verbose are appreciated, though.
Greetings

I have been doing a lot of searching lately, looking the the Net and
Newsgroups, but I am looking for a place where there are some really good
Perl examples. For instance, I see the descriptions of all of the commands,
but having a 3 or 4 line sample to go with it is invaluable.
For example, I am looking for some stuff that will pull down a directory
listing from a Unix Server (ie ls -l). I was originally using the Net::FTP
library (which worked just fine), but I ran into some parsing problems.
When I posted that, someone told me to use the File::Listing module, but I
don't see how to connect the two. Some sample code (along with the
description) really would have helped.

This solved the problem. Thank you very much. It seems that emacs always
includes at least one newline when you create a new file whereas windows
notepad does not.

Invalid argument? Is this error message from a check on an open or is it
being generated by a call to the system function, or maybe even something
else? Maybe posting some code would help, especially where it died...

And I think you're right, although it's hardly fair to say that
ActiveState Perl made your IIS break. ActiveState (I'm not a Windows fan,
but I can give credit where credit is due) have a pretty solid product
based on my own use of it.
Don't know about the "predating" part of your argument. Win95 predated
Win98 by 3 or 4 years, and Win98 fixed 3000+ bugs in Win95. So I wouldn't
go around touting the buglessness of IIS, particularly not when
practically every other server I've ever used on multiple platforms
handles Perl CGI nicely, thank you very much. :-)
ActiveState maintains a bunch of mailing lists, one or more of which
tackle problems like this one. I suggest you ask your question there, and
see what comes up. This is not a perl issue.
Arved
PS I just spent over a month with someone via email who was trying to get
IIS on NT to run Perl CGI. It's still not resolved (try diagnosing stuff
via email) but it's clearly not a Perl issue, as CGI's that ru on other
setips simply didn't on IIS. And I agree, I think it's all configuration.

Subject: Proposed module: GTK_Dialog
Message-Id: <791pt9$apj$1@pegasus.csx.cam.ac.uk>
Dear All,
As part of my degree project, I have to implement a dialog
entry system that reads data supplied by a user and enters it into an
SQL database. This must be scriptable - ie. users of my system must be
allowed to easily modify the form. It should run under X.
The obvious solution is to use a general purpose dialog module. None
seem to exist for any X toolkit. Could anyone point me towards one?
If, as I suspect, none exist, I intend to create one using GTK.pm
Details are not finalised yet, but I'd like to put in the following
features:
* Simple scripting syntax to create GTK widgets, and associate them
with elements of a hash array.
Something along the lines of (yes I know it's not quite correct Perl):
%myhash = GTK_Dialog(
title=>'Test dialog',
structure=>
column(
entry( title=>'Phone number',
size=>20,
regexp=>'m/\d+/',
errorstring=>'Phone numbers may only be numerical'
),
entry( title=>'Etc etc etc' )
)
);
print $myhash{"Phone number"};
* When the user closes the dialog, a hash array of the entry boxes,
etc. is returned.
* Entries may be validated on a regexp or user supplied callback
function.
* Validation failure can be an error or a warning, on a per entry
basis.
* Users will be able to specify strings or text files that are
displayed when the user clicks on help, or when validation fails.
* Our application will require it to safe when used as setuid or
setgid, so this will uppermost in my mind.
In my project, I can then write a program using this module to get
user input, and write it to an SQL database.
Any thoughts? For example, I'd be interested in your opinions on object
oriented vs. procedural for this.
Alistair Cunningham.

Here it is:
Server Error...
Something went wrong somewhere. It is most likely a code problem or if
you used a form that required an e-mail address it is
possible the e-mail address is incorrect.
Not very helpful. If you want to see the error in action you can go to

called Automail Lite that can send attachments using sendmail and
requires MIME::TOOLS. The script is form based, but could easily
be adapted to sending without form input.

Subject: simple database
Message-Id: <36b5690f.15966752@news.online.ee>
So,
I have a simple database:
item1: $type|$description|$name|$email
item2: $type|$description|$name|$email
etc.
this is all in a file.
I need to manipulate this database. Would hashes be the best in this
case. If yes, then how would i use them.
problem1:
i need to sort items by $type and then $description. (there are only a
few types at $type ).
problem2:
need to search the database and then print an item if $name eq
$namegiven & $email eq $emailgiven, and if nothing is found print
"Sorry" or something like that.

Is it a true proxy server that handles "GET http://foo.yahoo.com/"
through HTTP, or a CGI-like proxy server that fetches that
http://your.host.com/cgi/proxy/http://foo.yahoo.com/ for you,
rewriting the URLs on the way back?
I've written both kinds for my columns for WebTechniques (see
<URL:http://www.stonehenge.com/merlyn/WebTechniques/>. The first
(true) proxy requires setting up each browser that uses it.

Well, if it's the first kind, it shouldn't do that, unless your
browser has exceptions in its proxy list. If it's the CGI kind, then
you have to be VERY careful to rewrite *all* URLs that come back from
the data so that they point at your CGI script instead of the
originator. The one I forget on the initial design of the CGI-based
proxy was external redirects... when the server sends back:
Location: http://bar.yahoo.com/here/it/really/is/
in the HTTP response header. If you let that go through withou
rewriting it, you'll have lost the flow.

Like others have said, there's nothing Yahoo is doing that's unusual, but
you might have some coding errors.
(I'd be personally interested in seeing your code, if you don't mind.)

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.
