| Subject: | Net::FTP->new does not set $@ on timeout |
Net::FTP->new does not set $@ if a timeout occurs:
% cat timeout.pl
#!/usr/bin/perl
use warnings;
use strict;
use Net::FTP;
use Data::Dumper;
my $host = shift;
my $ftp = Net::FTP->new(
$host,
Timeout => 10,
Debug => 10,
);
if (!$ftp) {
print Dumper $@;
}
__END__
% perl timeout.pl $HOST
Net::FTP>>> Net::FTP(2.77)
Net::FTP>>> Exporter(5.62)
Net::FTP>>> Net::Cmd(2.29)
Net::FTP>>> IO::Socket::INET(1.31)
Net::FTP>>> IO::Socket(1.30_01)
Net::FTP>>> IO::Handle(1.27)
Net::FTP=GLOB(0x23c9c78): Timeout at timeout.pl line 9
$VAR1 = '';
The Net::FTP documentation says
| If the constructor fails undef will be returned and an error message
| will be in $@
but $@ stays empty.
It I set the timeout to a higher value (30 secs) everything works fine.
