[Freeswitch-users] recvEventTimed - SERVER_DISCONNECTED

5 Mar 2010

      Dear friends,
     I've faced an issue in event socket. I would want to know why it
behaves such a way.

     My program is working with the hep of events. So, based on the received
event, the process will continue it's work. When I need DTMF, I use
recvEventTimed and in the other cases, I use recvEvent.
     So, In the mid if caller hangsup, I expect for the SERVER_DISCONNECTED
event. When the caller hangsup when I'm waiting in recvEvent, I'm getting
SERVER_DISCONNECTED. But, when I'm waiting in recvEventTimed, I'mnot
receiving SERVER_DISCONNECTED, instead receiving an undefined value.

    To handle this, I've checked esl connection inside the timeout part and
put a recvEvent, then I receive SERVER_DISCONNECTED.

    My question is, why am I not receiving SERVER_DISCONNECTED when I recv
event using recvEventTimed?!

This is a sample program I execute,

require ESL;
use IO::Socket::INET;

my $ip = "127.0.0.1";
my $sock = new IO::Socket::INET ( LocalHost => $ip,  LocalPort => '9242',
Proto => 'tcp',  Listen => 1,  Reuse => 1 );
die "Could not create socket: $!\n" unless $sock;

for(;;) {
  my $new_sock = $sock->accept();
  my $pid = fork();
  if ($pid) {
    close($new_sock);
    next;
  }

  my $host = $new_sock->sockhost();
  my $fd = fileno($new_sock);

  my $con = new ESL::ESLconnection($fd);
  my $info = $con->getInfo();
  my $uuid = $info->getHeader("unique-id");
  printf "Connected call %s, from %s\n", $uuid,
$info->getHeader("caller-caller-id-number");

  my $e = $con->filter("unique-id", $uuid);
  if ($e) {
    print $e->serialize();
  } else {
    printf("WTF?\n");
  }

  $con->events("plain", "SERVER_DISCONNECTED DTMF");
  $con->execute("answer");

  while($con->connected()) {
    $e = $con->recvEvent();   ############# CASE 1 ##
    # $e = $con->recvEventTimed(10000);       ############# CASE 2 ##

    unless ($e) {
        unless ($con->connected()) {
###############################
           $e = $con->recvEvent();                         ##
           print $e->serialize();                               ##   Added
code to get SERVER_DISCONNECTED.
           print "SERVER_DISCONNECTED";     ##
        }
###############################
        print "DTMF timeout\n";
    }
    if ($e) {
      my $name = $e->getHeader("event-name");
      print "EVENT [$name]\n";
      if ($name eq "DTMF") {
        my $digit = $e->getHeader("dtmf-digit");
        my $duration = $e->getHeader("dtmf-duration");
        print "DTMF digit $digit ($duration)\n";
      }
    }
  }
  print "BYE\n";
  close($new_sock);
}
