Hi folks,
Perl is always killing me. I always do it on my computer first and then upload to the server in our lab. And oh my, never ever be correct to run on the lab. This time I got the internal error. I tried to add and delete multiple lines and found out that is possibly due to tie::File.
Could you please help me to solve the problem? I am dying for it :(
Here's the code. -
#!/usr/bin/perl
-
-
#use CGI::Carp qw(fatalsToBrowser);
-
-
#use strict;
-
-
use CGI;
-
-
use Tie::File;
-
-
$query = new CGI;
-
-
$data_file="nameList.cgi";
-
-
open(DAT, $data_file) || die("Could not open file!");
-
-
@raw_data=<DAT>;
-
-
tie @line, 'Tie::File', $data_file or die("Could not open file!");
-
-
print $query->header();
-
-
print "Content-type: text/html\n\n";
-
-
print "<HTML><HEAD>\n";
-
print "<TITLE>Thanks!</TITLE></HEAD>\n";
-
print "<BODY>";
-
-
$first = $query->param("first");
-
$last = $query->param("last");
-
$email = $query->param("email");
-
-
-
-
print "<P>$first $last, thank you for signing up! Please click <a href=\"list.pl\">here</a> to see the signup table for confirmation and don't repeatly signing up.</P>\n";
-
-
-
-
$count = 0;
-
-
@WS = $query->param("ws");
-
-
foreach $ws(@WS){
-
-
$line[$ws-1].="$first $last, $email|";
-
-
}
-
-
close(DAT);
-
-
print "</BODY>\n";
-
-
print "</HTML>\n";
-

I don't think the problem is with Tie::File. If you are running the script via a web server and getting a 500 internal server error the script may not even be compiling. Could be the path to perl is wrong or the scripts permissions are wrong or you uploaded the script in binary mode instead of text mode. If the problem was with Tie::File the CGI::Carp module should be printing an error to the screen. Any idea what version of perl you are using? Can you get any CGI scripts to work?
Yes, I can run other perl script which doesn't have that tie::File.
And I finally get my error log, here is the related error:
Can't locate Tie/File.pm in @INC (@INC contains: /usr/perl5/5.00503/sun4-solaris /usr/perl5/5.00503 /usr/perl5/site_perl/5.005/sun4-solaris /usr/perl5/site_perl/5.005 .) at /spare/WWW/cgi-bin/list.pl line 5.
BEGIN failed--compilation aborted at /spare/WWW/cgi-bin/list.pl line 5.

The problem is you are running a very old version of perl. Tie::File is not installed. I do not know if it will even work with such an old version of perl (5.005) . That mst be at least 10 years old. So for know you can't use Tie::File.
10 years old??? Oh my, yea....I searched on internet, saying that I missed a module, and I can add it to the makefile.pl. Hum....then I should let the website adminstrator to fix up that first. Thank you so much.
The module is installed, but I still get another error. Can anyone help??? Than.........ks !!!
Error:
Premature end of script headers:

The script I posted for you should not generate that error message unless the path to perl is wrong or you uploaded the script in binary mode instead of text mode. It looks like Tie::File will work with perl 5.005.
KevinADC, yes, I did use WS_FTP32 binary mode to upload the file, but seems other pl files are ok, only the file I am working on has problem T_T And this FTP program has twp options: ASCII and binary.

Try uploading in ASCII mode which is text mode. If that does not work, I am not sure what the problem is unless the path to perl is wrong.
I tried, and it is wierd. When I upload it in binary mode, I got the errror"prematur e end of script headers". And when I uploaded it in ASCII mode, I got "Can't locate warnings.pm in @INC " again. But our web administrator had already install the Tie module. Oh, my, this seems like endless. I really really appreciate your help, KevinADC.

The problem has to be the very old version of perl you are using. You are trying to write modern code using an outdated version of perl. Evidently the warnings pragma is not included with that version of perl:
use warnings;
remove that and use the -w switch on the shebang line:
#!/usr/bin/perl -w
but the best solution is use a newer version of perl. You will continue to have problems and you will just get frustrated. Ask the tech guys to upgrade perl if at all possible.

In Perl, there is a module called "Tie::File". What it does is tie a
list to each line of a file. Change the list, and the file is
automatically changed, and on top of this, only the bits of the file
that need to be changed are written to disk. At least, that's the
general idea.
I was wondering if something roughly similar could be done in Python,
or at the very least, if I can avoid doing what amounts to reading the
whole file into...

Hello,
In Perl, using a Tie::File module I can easily and comfortably delete
a line from the middle of a text file:
my @file;
open(DATA, "+<:encoding(utf8):raw" , "file.txt") or return 0;
tie @file, 'Tie::File', \*DATA or return 0;
splice(@file, $_, 1);

Many websites have a form or a link you can use to download a file. You click a form button or click on a link and after a moment or two a file download dialog box pops-up in your web browser and prompts you for some instructions, such as “open” or “save“. I’m going to show you how to do that using a perl script.
