The problem I can find can be found by running the following code in Strawberry perl 5.12.3.0 on Windows XP.
use strict;
use warnings;
use Win32::Unicode::File;
use Encode;
my $fname = shift @ARGV;
my $fh = Win32::Unicode::File->new;
if ($fh->open('<', $fname)){
while (my $line = $fh->readline()){}
close $fh;
}else{
print "Couldn't open file: $!\n";
}
The only thing happening here is that I am doing a readline, and that continues to have memory until I get an error from memory from Strawberry perl. I use a really large file, but since this code is stream based, it doesn’t matter. Am I missing something here or is there a leak somewhere in Strawberry perl? I tested the exact same code in ActivePerl and there it works fine, i.e. He does not eat memory.
Update: replacing Win32 :: Unicode :: A file with a regular diamond operator seems to work at least on my distribution. See the following code.
use strict;
use warnings;
my $fname = shift @ARGV;
if (open(my $fh, '<', $fname)){
while (my $line = <$fh>){}
close $fh;
}else{ print "Couldn't open file: $!\n";}
, , Win32:: Unicode?
