Hi
I get a warning message "Use of uninitialized value $3 in hash element
at test.pl line 13." when I run the code below (using Perl 5.10). How
I can fix this in a neat way ?
Thanks for any help !
[code]
!/usr/bin/perl -w
use strict;
my %fs;
my @df;
$df[0] = "udev 125320 152 125168 1% /dev";
foreach (@df)
{
if (/\d+\s+\d+\s+(\d+)\s+(\d+)\%\s+(?!\/cdrom)/)
{
$fs{$3} = 1;
}
}

You expected (?!\/cdrom) to act as a third set of capturing parentheses,
setting $3 to everything after the %\s+ as well as causing the match to fail
if what comes next is "/cdrom"? It doesn't. Look-aheads, like other fun
things starting with "(?", are not capturing groups. Those are non-capturing
parentheses. Add another (.*) to the end of the regexp.

I don't know why the ? is inside the () in the above regex. If you shift
it one place left, outside the () then the code does not error. Though I
don't know what difference that'll make to your regex.

That is what I am currently working on...giving a perl
face to S60. There are two of us mainly, me and Osvaldo Villalon. We
had quite a bit of work to just getting Jarkko's work cohesive with
current sources.
We work on this as our time allows. You know the deal:
this is an all volunteer effort etc etc
Between work, grad school, home life, yeah, I get to it
when I can. :)
Anyway, I take objection to your negativity. This is the
sort of thing that pesters what should be a happy open source community.
What I wish you would have said is:
"Really? I am jealous of the S60 functionality the
python guys have. Where are you in development of this and can you give
us
a road map to where you want to go in terms of allowing a richer set
of APIs? What can interested parties do to help?"
I have answers to these questions but, sadly, you didn't
ask. Did you?

There's nothing wrong with goto when used properly. Like any tool, it can
be and often is misused, but it's useful in its place.

if you consistantly or even occasionally use goto then i won't
recommend you for a job. magic goto being the only exception, perl has
little use for goto. you can easily code around it with all the great
flow control options we have. one trick is to use more subs and return
early from them.
and the OP's code is beyond redemption. he obviously CHOSE goto and no
subs which makes him a BASIC coder.

Yes, there are sometimes special cicumstances which occasionally justify
a goto. But none of the OP's calls fall into that category and actually
his resulting spaghetti code is a prime example why Edsger Dijkstra's
"Go To Statement Considered Harmful" is as valid today as it was 40
years ago.

Hmm, from other postings I see that you use hash of arrays. Then
130GB does not look excessive...

Perhaps because it's supposed to be video/mpeg. Similarly, the MIME type
for a .avi file is video/x-msvideo.

OK, so the root of my problem seems to that the video subtype is
wrong.
Changing video/mpg to video/mpeg fixes the problem for mpeg, but the
problem remains for the asf and avi files. For asf files I tried
video/asf and video/x-ms-asf, and for avi files I tried video/avi,
video/msvideo and video/x-msvideo' all to no avail. I found each of
the variants I tried on the web (such as www.webmaster-toolkit.com/mime-typ=
es.shtml
and pcs.cruz-network.net/faq.php, to list only two of those pages I
found).
NB: My line that sets content type has been changed to:
print $query->header('-content-type' =3D> "video/$format",'-content-
length' =3D> $flength);
I figured I might as well set the content length header at the same
time.
I did notice that once I changed video/mpg to video/mpeg, the client
added the mpg extension to the script name and the media player opened
immediately. With the other formats, it left the script name
unchanged. Now, if I tell it to display the content using the media
player, the content is displayed.
Any ideas on what to use for the MIME subtype for AVI and ASF files
that would be recognized by clients like firefox and MS IE?
Thanks
Ted

It should work. Try this test program:
#!/usr/bin/perl
use strict;
use warnings;
use CGI qw/-no_xhtml :standard/;
my $file = 'content.avi';
print header(
'-content_type' => 'video/avi',
'-content_disposition' => 'attachment; filename=result.avi',
);
open my $fh, '<', $file or die("Failure: $!");
fpassthrough($fh);
close $fh;

local $/ = \1000;
local $_;

Yup. I had to edit a bit so it would work on Windows (path to perl
and use binmode on the file handle), but that worked. So I have to
compare that with what I had yesterday to discover why mine didn't
work.
Do you know if that works for mpeg and asf files? What would you set
the content type to? And I notice you don't set content length with
this.
Thanks.

There's no need to guess - just look at Apache's mime.types file to see
what MIME type it maps to a given filename extension. The relevant lines
from my local copy of that file are:
video/x-msvideo avi
video/x-ms-asf asf asx

OK, On mine, there is a line like your's for avi files, but there is
nothing in the mime.types file on my system for asf files. This is
puzzling since everything works well if I just redirect to an asf file
in htdocs instead of setting the content type and then writing the
content of the file to standard out in binary mode.
But that doesn't cover what is happening on the client side. Even
though the server may not send video/avi as the MIME type for an avi
file, both Firefox and MS IE recognize video/avi. I know this because
Mumia's latest example worked fine even though he set the content type
to video/avi. That give's me an idea, from what you said and what
Mumia's example does, that I will have to test after lunch.
Cheers,
Ted

Of course, the URL is http://host/cgi-bin/script.pl or something like
that. The browser thinks the file is called "script.pl".
An easy way to change this is to use the URL
http://host/cgi-bin/script.pl/file.avi (or whatever file name you want to
have). Apache will know to actually call your script.pl, and not try to
access script.pl as a directory.

So that those running an older version of Perl will get a sensible error
message.

K3wl; there's only one program on your machine written in Perl? Because if
there are two then there's no guaranty that you want to use the new
features of Perl 5.10 in both. If you're distributing your code to the
outside world, then it is reasonable to indicate in the code the oldest
version of Perl that you support.

Only for those who never share code with anybody else.
