It looks like your FIFO is only used for the child to speak to the parent. Would a regular pipe serve better? It would be faster. while (my $connection = $listen_socket->accept)
{
my ($pid, $line, $in, $out);
pipe $in, $out or die $!;
if ($pid = fork) {
close($out);
warn localtime(time),
" Connection recieved ... ",
$connection->peerhost,
$/;
$connection->close();
# microsleep till the kid's awake
do { select undef, undef, undef,.001} until kill 0, $pid;
+
while(<$in>){$_ =~ s/a-z/A-Z/i;print $_;}
close($in);
}
elsif (defined $pid){
close($in);
$listen_socket->close;
while(<$connection>){print $out $_;};
close($out);
exit 0;
}
else {
die "Error while forking: $@" unless defined $pid;
}
}
There may be a lot more to do to make this work with your real application, particularly if there is to be more than one connection at a time. In that case, the parent will need to listen on the socket and several pipes at once.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
