I'm working on a server daemon program that
will provide a running "tail" of a log file
to clients connected with "telnet". To start
with, I used the forking server shown on
pages 350-351 in Chapter 6 of the
book. I modified
the
spawn call so that the code
looks like this...
spawn sub {
my($nodie) = 1;
my(@tail) = ();
my($err) = 0;
print "Hello there, $name, it's now ", scalar localtime, $EOL;
open(REQLOG,$ReqLog) || confess "can't open $ReqLog: $!";
while(<REQLOG>) {
push(@tail,$_);
if($#tail>10) { shift(@tail); }
}
foreach(@tail) { print $_,"\r"; }
while($nodie) {
while(<REQLOG>) {
if(! print $_,"\r") {
confess "can't print to socket: $!";
$nodie = 0; last;
}
}
}
sleep(5); seek(REQLOG,0,1);
}
};
}
The "tailing" procedure works just fine, the problem
happens when I disconnect from the client side. The
forked server sending data to the client doesn't exit.
I don't get any messages. Is there a signal I'm
supposed to be looking for here?
Thanks in advance.
