This is some AI generating a Perl preforking HTTP server.
use IO::Prefork;
use LWP::UserAgent;
use Time::HiRes qw(gettimeofday);
use Socket;
my $prefork = IO::Prefork->new();
$prefork->listen(4000, '127.0.0.1');
sub handle_request {
my ($req, $env) = @_;
my $now = gettimeofday();
print STDERR "Request received: $req\n";
# fork a new process for this request
my $pid = fork();
if ($pid == 0) {
# child process, handle the request
eval {
$prefork->handler($req, $env);
};
if (WANTED_EXIT_CODE) {
exit(WANTED_EXIT_CODE);
}
} else {
# parent process, wait for child to finish and handle its result
my $child_exit_code = wait();
die "Child process did not exit cleanly: $child_exit_code" if ($child_exit_code != 0);
# send the result of the request back to the client
my $response = $prefork->result;
print STDERR "Sending response back to client\n";
print $response;
}
# log the time it took to handle this request
my $elapsed_time = $now[3] - $now[2];
print STDERR "Request processed in $elapsed_time seconds\n";
}
$prefork->process({ 'id' => 1, 'cmd' => sub { exec("/usr/bin/php-fpm")->out(0); } });
First problem: IO::Prefork doesn't exist. And that functionality wouldn't go in the IO:: namespace anyway.
Second problem: It seems to want to do the forking in handle_request(), which would imply it's forking during each request, not before requests, as asked. I say "seems" because handle_request() isn't used anywhere, anyway.
The cherry on top is the last line, where it just execs php-fpm anyway.
