Hello,
I'm trying to write a daemon which will restart itself when it receives SIGHUP. Whenever I send the signal, the daemon never seems to start a new one using the system call (I get a return code of 512 - what does that mean?).
I'm using the following code:
#!/usr/local/bin/perl -w
use Proc::Daemon;
use strict;
my $root = "/temp";
my $time_to_die = 0;
sub signal_handler
{
$time_to_die = 1;
}
sub phoenix
{
my $me = "$root/minidaemon.pl";
logMessage("I'm about to refork by running '$me'!");
my $ret = system($me);
if ($ret)
{
logMessage("Should have run system($me), but which returned $r
+et: $?, carrying on");
}
else
{
exit(0);
}
}
sub logMessage
{
my $message = shift;
local $| = 1;
open(FILE_HANDLE, ">>$root/daemon.out") or die("log file open fail
+ed: $!");
print FILE_HANDLE "$$ : $message\n" ;
close(FILE_HANDLE);
}
Proc::Daemon::Init;
$SIG{INT} = $SIG{TERM} = \&signal_handler;
$SIG{HUP} = \&phoenix;
while (!$time_to_die)
{
sleep(1);
logMessage("hello");
}
logMessage("died");
I know I am probably missing something very obvious, but this initiate hasn't got a scooby. Thanks in advance!
