try a less famous signal like SIGUSR1 it's possible something in perl still reacts to SIGINT On Mon, Jan 18, 2010 at 5:22 AM, lakshmanan ganapathy <lakindia89@gmail.com>wrote:
Here is the result

my $uuid = $info->getHeader("unique-id");
printf "Connected call %s, from %s\n", $uuid, $info->getHeader("caller-caller-id-number"); my $r=$con->execute("answer"); print Dumper $r; $con->events("plain","all"); my $re=$con->execute("playback","/usr/local/freeswitch1/sounds/en/us/callie/ivr/8000/ivr-welcome_to_freeswitch.wav"); while($con->connected()) { my $e = $con->recvEvent();

I executed the program and the following things were printed
CHILD PID: 6778 Connected call e0d1001a-03f4-11df-b002-db488337e0ea, from 1001 $VAR1 = 0; EVENT [CHANNEL_EXECUTE] EVENT [CHANNEL_ANSWER] EVENT [CHANNEL_EXECUTE_COMPLETE] EVENT [COMMAND] EVENT [CHANNEL_EXECUTE] EVENT [HEARTBEAT] EVENT [RE_SCHEDULE] EVENT [CHANNEL_EXECUTE_COMPLETE]
Then from another shell I executed kill -2 6778, the result is follows CHILD 6778: SIGNAL SIGINT is generated EVENT [SERVER_DISCONNECTED]
But the child process is still running as expected. But I don't know why I received SERVER_DISCONNECTED from freeswitch???

I taught the signal handler will be inherited by the child process. It also does like that. After making a call, If I press ctrl + c, the above program printed PARENT PID: Signal SIGINT is generated CHILD PID: Signal SIGINT is generated.
So I think the sigal handlers will be inherited to the child. Anyway I'll also try registering signal handlers in child also, and then I'll come back with that result.

you would have to register signals in your child process too

Hi all,
I've done a sample program (In perl ESL) , which play a file to the caller and then it will call recvEvent() and print the event name. I've handled signals also.
When I send SIGINT to my program (Perl), the signal handler is called and I can see the print output. But in the same time, I received SERVER_DISCONNECTED from freeswitch as event.
I don't know why I received SERVER_DISCONNECTED from freeswitch. Is it because, the recvEvent() from perl internally calls the recvevent function in the Esl.c and when it waits to receive the information from socket, the signal occurred???
Please clarify me!!
Here is my program require ESL; use IO::Socket::INET; use Data::Dumper;
my $ip = "192.168.1.222"; my $sock = new IO::Socket::INET ( LocalHost => $ip, LocalPort => '8447', Proto => 'tcp', Listen => 1, Reuse => 1 ); die "Could not create socket: $!\n" unless $sock; ®ister_Signals();
for(;;) { my $new_sock = $sock->accept(); next if (not defined ($new_sock)); my $pid = fork(); if ($pid) { close($new_sock); next; } print "CHILD PID: $$\n"; my $host = $new_sock->sockhost(); my $fd = fileno($new_sock);
my $con = new ESL::ESLconnection($fd); my $info = $con->getInfo();
my $uuid = $info->getHeader("unique-id");
printf "Connected call %s, from %s\n", $uuid, $info->getHeader("caller-caller-id-number"); my $r=$con->execute("answer"); print Dumper $r; $con->events("plain","all"); my $re=$con->execute("playback","/usr/local/freeswitch1/sounds/en/us/callie/ivr/8000/ivr-welcome_to_freeswitch.wav");
while($con->connected()) { my $e = $con->recvEvent();
if ($e) { my $name = $e->getHeader("event-name"); print "EVENT [$name]\n"; if ($name eq "DTMF") { my $digit = $e->getHeader("dtmf-digit"); print "$digit\n"; } } } close($new_sock); } sub register_Signals() { foreach ( keys %SIG ) { $SIG{$_} = 'sig_Handler'; } }
sub sig_Handler() { my $handle=$_[0]; if($handle eq "INT") { print "$$: SIGNAL SIG$handle is generated\n"; } }
