First thank you for your participation, The code I posted is all I have, the server is HTTP::Server::PSGI, the memory I have is 1.5gb, the file is a iso of 2.30 GB, the code is running in virtual machine VMware Workstation

I can't reproduce.
I've created a 2 GB file with dd, hardcoded its name in my script in Re: Download big file in chunks with plack response, executed ulimit -v 1000000 to limit available memory, then in the same shell ran the server as plackup script.pl. From a different terminal I've then ran curl http://localhost:5000 -o /tmp/thing.
Predictably, the server died with "Out of memory". Then, I've commented out the slurp line, as I've suggested earlier. Predictably, the server proceeded to serve the file and didn't die.
What are you actually doing, and what is your exact error message?
(I had to add a line \&return_psgi; for it to work with plackup, and I hardcoded the file name because I'm not aware of a way for a PSGI a handler to get a file name as an argument, so I suspect there is something else in the picture that you're not telling us.)

Hello there kikuchiyo
A big thank you for you testing, now the code is working
The problem was, I was using plackup -L Shotgun to run the psgi app, and the error I was getting was.
Magic number checking on storable string failed at /usr/lib/x86_64-linux-gnu/perl/5.22/Storable.pm line 420, at /usr/local/share/perl/5.22.1/Plack/Loader/Shotgun.pm line 35. Sometimes I get the error memory
But when I change to just plackup, everything works
here is the final code:
use strict;
use warnings;
####use Plack::Response; # doesn't seem to support streaming response
use Path::Tiny;
use File::MimeInfo;
my $app = sub {
my $env = shift;
my $path_file = 'win.iso';
my $content_type = mimetype($path_file);
$content_type = 'application/octet-stream' if not defined $content
+_type;
require File::Spec::Unix;
my $basename = $path_file;
$basename =~ s|\\|/|g;
$basename = ( File::Spec::Unix->splitpath($basename) )[2];
$basename =~ s|[^\w\.-]+|_|g;
return sub {
my $responder = shift;
my $writer = $responder->(
[ 200, [
'Content-Type' => $content_type,
'Content-Disposition' => qq[attachment; filename="$
+basename"],
]
]
);
open (FILE, "< $path_file") or die "can't open $path_file: $!"
+;
binmode FILE;
local $/ = \102400;
while (<FILE>) {
$writer->write($_);
}
$writer->close();
close FILE;
}
}
again thank you so much for your time and your code | [reply]
