Delivering Graphics over HTTP
I need to deliver graphic files (jpg and gif) over http in the same manner that a web server would. Can anyone point me in the right direction? Setting the mime type is no problem but it's the rest that I have no experience of. In the past I've always simply done a location: /path/to/graphic but the graphics are getting cached somewhere along the line so I need to set Cache-control: no-cache and the only way I can think of to do this is if my script does the delivery itself. I don't have access to the configuration of the web server. Unless it possible to do it in .htaccess? I tried the following in .htaccess but no joy, is there a better way of doing this with .htaccess? Possibly at HTTP 1.0 server somewhere in the chain is preventing it from working? Header add Cache-Control "no-cache" Header add Cache-Control "no-cache" TIA Nigel -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The ->join waits.
$thread->join() means wait for the $thread to complete and reap it.

It seems you use a module that was not made thread safe.
Since you see this when a thread finishes I'd think this is caused by
some object destruction. It seems that some object is DESTROYed and
it destroys some shared data.
If you create some objects before the thread creation you may want to
try to bless() them into a different package to prevent the normal
DESTROY.
You may either do
@Fake::Object::Class::ISA = qw(Object::Class);
sub Fake::Object::Class::DESTROY {}
bless $object, 'Fake::Object::Class';
as soon as possible in each thread or
bless $object, 'Do not destroy';
before the thread finishes.
It's safer to do the first.
You may also try to pospone loading of some modules AFTER you create
the threads. So that each thread loads the module separately.
Sometimes this helps.

Perl version of xcopy on Win32?

Hi,
Hello,
I'm a beginner at PERL. I've used it on and off, but only
just recently got myself back into the picture. I figured
that if you forget something in PERL, it'd be easy to take
it up again. So far, I'm not too sure of the ease
of taking up PERL again. Before, I made a few perl scripts.
Now, when I look back, I find the whole thing overwhelming.
Even with comments...Anyway, I digress..
I have a text file with each line of the following format:
string1 string2 val1 val2 val3
I'm trying to read it into an array of arrays so I can
stick it in the creategraph() function to create a line
graph.
So far, if I specifically create an array constant:
ie.
my(@data) = ( ["test 1",0.34,0.56,0.33],
["test 2",0.44,0.55,0.22],
["final test",0.67,0.22,0.54])
my($grp) = new GD::Graph::linespoints();
and then put that in the $grp->plot([EMAIL PROTECTED]) function, I get
a graph.
But, if I use the following code:
while (){
chomp($_);
@info = split(" ",$_);
my($strngval) = "\"$info[0] $info[1]\"";
$strval = "$strval,$strngval";
$m1vals = "$m1vals,$info[2]";
$m2vals = "$m2vals,$info[3]";
}
From your description, you probably want something like this:
my @data;
while ( ) {
my ( $str1, $str2, @info ) = split;
push @data, [ "$str1 $str2", @info ];
}
I just realized that I had actually seperated the data
into homogenous arrays; that is, one array carries all
the string values, one consists of one set of values,
and the last array consisting of the maximum values.
I'm beginning to understand where I goofed.
You could use the Data::Dumper module to display the contents of @data:
use Data::Dumper;
print Dumper( [EMAIL PROTECTED] );
Thanks for the help! Very much appreciated.

execute external program in sever/client enviroment via open
hi all,
I've problem with executing an external program in my perl program. I'm trying to
build an server for managing pop3 accounts to which I can connect for example via php
sockets.
For server/client enviroment I'm using Net::Server perl module. Everything works all
right, until I need to run external 'pw' script. Then client connection to my server
closes without any errors messages.
If I use the same code (specified below) in my simple test file everything works.
This code is specified in child process of my server, which is created after
connection to it (in 'process_request' subroutine of Net::Server::Fork module).
Here is the problematic part of code:
$tmp = "$pw_path useradd";
$tmp .= " -n " . $username;
$tmp .= " -q -m -s " . $shell;
$tmp .= " -h 0";
if( defined(open(PW,"| $tmp")) ) { # here client closes the connection
print PW $password, "\n";
close PW or warn "$pw_path exited on $?: $!";
} else {
print "$pw_path failure: $! ($?)";
}
1;
'pw' script needs some command line arguments defined in variable $tmp which is passed
to open.
'-h 0' argument make pw to wait for password to be specified on standart input, so I
need build an pipe to it.
I'm running FreeBSD 4.7 with perl 5.005_03 and Net-Server-0.83.
Pease help me to figure what I have done wrong.
Thank you.

while seeing this one, it could be you meant:
/\d{1,3}([.,]\d{0,2})?/
However, there are two main problems in your trial:
First it seems to be wrong to escape the backslash,
as \\d is very different from \d.
Second, the optional , followed (if necessary) by digits is best expressed
completely as one optional group ([.,]\d{0,2})?

Is $pw_path the entire path or relative.
I've found on my freebsd box that I had to have the entire path to htpasswd to modift
.htpasswd files.
Not sure if pw is the same as passwd in the sense that :
1) Unless you're root passwd changes the current user's passwd only, so you may be
trying to change nobody or www password
2) Even if the script is running setuid you would still be changing only the script's
owner's password.
But if it is then the script may be trying to change a passord it has no permission to.
FreeBSd is great about security and it wouldn't be too secure to let one script change
everyone's passwords via some evil troll.

RE: Delivering Graphics over HTTP
I assume what you're trying to do is have in your html
And maybe except paramkaters and display accordingly?
If so all you need to remember is to print the proper headers and don't try to print
and text.
#!/usr/bin/perl
use File::Slurp;
use CGI qw/:standard/;
print header("image/gif");
print read_file("/path/to/img.gif");
Of course you can do all kinds of things like check for
errors modify the images using various image modules display different images based on
inout, etc, etc

RE: execute external program in sever/client enviroment via open
hello,
- $pw_path contains the absolute path to pw: /usr/sbin/pw
- I run server as root, if I try to print $< in program it returns 0 which is ok, so
privileges should be ok
- one on the end isn't important - it's just for setting an return value from
subroutine
As I write, code should be ok, because if I run it allone, outside my program it
works. I think there is maybe some restrictions which I don't know, for example under
fork I can't execute external command, or when I use strict mode I can't run it or
something similar.
- I did mistake in comment of code.. of course server closes connection, not client.
I'm testing my server by telneting to its port.
anyway thank you for your answer.

I don't know much about the problem you are asking for.
But it seems to me that you're wrong when calling the subroutine wanted.

sub wanted;
It must be:

Shouldn't it???

It's actauilly not clling the routine it's declaring it. So it is valid perl but it's
not actually calling it.

how to mimic cursor movement in a Perl script
Hi, I am try to automate a analysis process, In which I used a windows box to telnet a UNIX box and do the job on the telnet consol. I need to use move the cursor down or up and also need to use Control key plus a certain cahracter key to do the operation. Ideally I sould type a few characters after move the cursor to a centain position. My question is how to write a Perl script to do it? I do not want to sit here do it over and over for weeks!

The keys you press may be either: 1. Interpreted by your Windows terminal emulation software and handled by it in some fashion, or 2. Passed over to the UNIX side and handled by the device driver and/or application program running there. For (1) (and possibly (2)), you would need to look at scripting capabilities built into your terminal emulation software. For (2), you can use Perl's Net::Telnet (from the client) or Expect (from the server) modules to write a script to manipulate the application. This script would stand in the place of your terminal emulator. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: convert pdf files to text using Perl
Hello,
>
> How do I convert pdf file (Acrobat readable format) to text,
Convert to text not sure..
Have you looked at http://search.cpan.org and searched for pdf under modules?
Using/getting pdf into your script is easy :
#!/usr/bin/perl
use File::Slurp;
use CGI qw/:standard/;
print header("application/pdf");
print read_file("/path/to/my.pdf");
# or
# $pdf_guts = read_file("/path/to/my.pdf");
# do what you want with pdf guts, like translate them into text or html if possible!
If you don't want to output he pdf to the screen
but want other output ( html ) then do print header();
Of course you can do all kinds of things like check for
errors modify the pdf using various image modules display
different pdfs based on input, email the odf as an attchment etc, etc
This is a two for one reply!
( If any one read the exact sam one about images an hour or so ago. )

It will also grab [[ and ]] and ][ which don't appear possible from your

in the second and want to exclude [[, ]], and ][, then try:

http://search.cpan.org is your friend

I'll leave it to you to look on cpan for something that
will list all recursively if that's what you're asking.

RE: formating numbers.
There was a post about this exact thing a few weeks or so ago. I can't remember who
posted it but
Here is what I use, works like a monkey in heat!
#!/usr/bin/perl
$commify_this_number = $ARGV[0];
$commify_this_number =~ s/(^[-+]?\d+?(?=(?>(?:\d{3})+)(?!\d))|\G\d{3}(?=\d))/$1,/g;
print $commify_this_number;
It will put commas in the proper places on digits to the left of a decimal or letters.

A generalized 'commify' sub looks something like this:
sub commify
{
my $nbr = reverse shift;
$nbr =~ s/(\d\d\d)(?=\d)(?!\d*\.)/$1,/g;
return scalar reverse $nbr;
}
Just call it - baring typos, it should work.

Straight from the Perl Cookbook:
sub commify {
my $text = reverse $_[0];
$text =~ s/(\d\d\d)(?=\d)(?!\d*\.)/$1,/g;
return scalar reverse $text;
}
Just feed it a number and either print the return or place in a variable to work with.
Wags ;)

shifting through arrays of line data
Hi Guys,
I have an array in which each element is a line commandline data. It looks
something like this -
@Array contains lines:
post1: -r [EMAIL PROTECTED] -x cat-100 -h post1
post2: -x tel -h post2
post3: -h post3 -x hifi
And so on. The order of the options varies, and there may or may not be a
-r $arg on the line.
These lines are parsed from a file with more lines, of which I extracted all
the lines with -h:
open (F, "<$File");
while () {
if ($_ =~ / -h /) {
# remove crud
s/ \"\|//;
s/\/some\/crud\/path argument //;
s/\"$//;
# store what's left
push @Array, $_;
}
}
What I really need to do is build a relationship between the first field
(which is the same as the argument to -h) and the argument to -x. The -x flag
can be dropped, as they're not needed.
So it looks like I need to build a hash based.
But I can't can't grok how to parse each line out to do what I need, then
move on to the next line (all lines are unrelated to each other).
I've been using shift, but then I'm doing something like, (psuedo code):
if ($_[0] eq "-r") { $r = (shift);}
but if sub 0 doesn't eq -r, and I shift until I get to -x, say, and use that
for the $x = (shift), how can I be efficient to check again for -r, which I
still haven't found?
Is this making any sense?
Thanks,
deb

Re: shifting through arrays of line data
Thanks, I know how to use split (I think). Since the data comes in
any order, and I have to corellate it, I can't think of a way that split
will fix me up - Maybe I'm missing something. Can you give me an example?

Ok I'll give her a go
my %results;
my $cnt = 1;
foreach $line(@Array) {
my %tmp;
my $switch;
my $value;
%tmp = split(/\s/, $line);
# this assumes that every piece of data has a switch so it wouldn't work on '-I love
you' because -I and love
# would be together but then you would be lonely , it would especially be bad if it
had switches after it
# '-I love you -j enny -I mforestgump'
# if this is the case you may have to put it in an array and process that somehow to
get the switch/value combos
# and then do something with the bare values ( I guess I should be calling them
arguments oh well )
foreach $switch(keys %tmp) {
$results{$cnt}{$switch} = $value;
}
$cnt++
}
print $results{'1'}{'-h'}; # would print post1 from your three line example below
Give that a go and see if it doesn't help!

Crypt::Blowfish errors on line 56
Hi Folks, The code at http://longren.no-ip.org/tyler/blowfish.pl encrypts some $data. Once the data is encrypted, the hex value should be stored in $ciphertext. $plaintext should have the original data that's in $data. When I run this code, I recieve this error: "input must be 8 bytes long at /usr/lib/perl5/site_perl/i386-linux/Crypt/Blowfish.pm line 56." Does anybody know why this happens?

According to the documentation for this module:
NOTES
The module is capable of being used with Crypt::CBC. You're encouraged
to read
the perldoc for Crypt::CBC if you intend to use this module for Cipher
Block
Chaining modes. In fact, if you have any intentions of encrypting more
than
eight bytes of data with this, or any other block cipher, you're going
to need
some type of block chaining help. Crypt::CBC tends to be very good at
this. If
^^
you're not going to encrypt more than eight bytes, your data must be
exactly
eight bytes long. If need be, do your own padding. "\0" as a null byte
is
^
perfectly valid to use for this. Additionally, the current maintainer
for
Crypt::Blowfish may or may not release Crypt::CBC_R which replaces the
default
'RandomIV' initialization vector in Crypt::CBC with a random
initialization
vector. (to the limits of /dev/urandom and associates) In either case,
please
email [EMAIL PROTECTED] for Crypt::CBC_R.
Your data is only five bytes long.
my $data = pack 'a8', '54321';

If you want to put the data into a hash this may do what you want:
$ perl -le'
@array = (
"post1: -r [EMAIL PROTECTED] -x cat-100 -h post1",
"post2: -x tel -h post2",
"post3: -h post3 -x hifi"
);
for ( @array ) {
%hash = /(-[a-z])\s*((?!-)\S*)/g;
$" = " <*> ";
print "*> @{[%hash]} <*";
}'
*> -r <*> [EMAIL PROTECTED] <*> -h <*> post1 <*> -x <*> cat-100 <*
*> -h <*> post2 <*> -x <*> tel <*
*> -h <*> post3 <*> -x <*> hifi <*

If so, then you can scan through the headers [preferably on initial input], looking for the first instance where a line does not start with "Content-", and is not a continuation of another line starting with that string. Also, we know from doing CGI that the header section must always be followed by an empty line. When your program detects that it is reading a header, it can watch for that empty line to mark the start of the content described in the header. For the end of the content of any given mime, you already have the flag line to watch for. When you read it, you can discrad all empty lines between the end of content and the divider.

Yes. The module is File::Find. You should search for the Find.pm file in a File
directory in one of your lib directories. You can then test your script against that
benchmark to evaluate it.
Since Perl is an open-source language, you can also open the file up in a text or code
editor, and study the way it executes its work. This may give you some insight into
the recursive process. Since recursion most closely reflect the nature of the veast
being processed, it is very likely that the module performs its work through recursion.

Hi Deb,
Is this something like what you are looking for?
sub getRelationship($, $) {
my ($commandline, $relationships) = @_
my @commands = split /\s -/, $commandline = @_;
my $key = shift(@commands);
foreach (@commands) {
if (/^x/) {
s/^x\s+//;
$$relationships{$key} = $commandline;
}
}
}
This should put a string containing all parameter to any -x command into the hash
referenced by $relationships.

It mgght be interesting also to show how you can just LOOK at a number like
2,305,843,008,159,952,128 and know that it has about about a one-in-four chance of
being one of the eight "perfect numbers" found within the range from zero to that
number.

What is the comma doing there?

Missing semicolon.

^^
Why are you assigning the array size to $commandline?

There is no need to do a match AND a substitution.
if ( s/^x\s+// ) {

Hi John,
Thanks for catching that. I guess i shold run my psuedocode through the command line
instead of composing it in the mailer. Cleaned it up a little, ut it in a test stub,
and now it achieves the functionality described:
#!/usr/bin/perl -w
use strict;
use warnings;
my $string = "post1: -r [EMAIL PROTECTED] -x cat-100 -h post1";
my %relationships;
sub getRelationship($$);
getRelationship($string, \%relationships);
sub getRelationship ($$) {
my ($commandline, $relationships) = @_;
print "$commandline\n";
my @commands = split /\s+-/, $commandline;
my $key = shift(@commands);
foreach (@commands) {
if (s/^x\s+//) {$$relationships{$key} = $_;}
}
}
foreach my $key (keys %relationships) {
print "$key:=$relationships{$key}\n";
}

The getRelationships sub here has a few less typos, and the test stub runs well.
#!/usr/bin/perl -w
use strict;
use warnings;
sub getRelationship($$);
testGetRelationships();
sub testGetRelationships {
my $string = "post1: -r [EMAIL PROTECTED] -x cat-100 -h post1";
my %relationships;
getRelationship($string, \%relationships);
foreach my $key (keys %relationships) {
print "$key:=$relationships{$key}\n";
}
}
sub getRelationship ($$) {
my ($commandline, $relationships) = @_;
# print "$commandline\n"; #debug
my @commands = split /\s+-/, $commandline;
my $key = shift(@commands);
foreach (@commands) {
if (s/^x\s+//) {$$relationships{$key} = $_;}
}
}
