Hello all,
Any help on this question would be appreciated. I am a newbie to this site, so I have not figured my way around yet. Forgive me if this question is answered somewhere else.
My application runs on RH Linux. I have set of perl processes that are communicating through a UNIX socket.
my $s = IO::Socket::UNIX->new(
Type => SOCK_STREAM,
Local => $sockname,
Listen => 10,
ReuseAddr => 1,
);
One of these processes goes away for an extended period of time and comes back eventually. During the time that it is gone it is not able to read from it's pipe. This is causing the other process that is writing to the pipe to wait for an extended period of time. When this happens, bad things occur in my application.
One idea I would like to try is to set the socket's underlying recieve buffer to as large as possib!
le.
Questions:
Can anyone tell me how to set the socket's underlying receive buffer size?
What is the maximum size that the buffer can be?
From reading the perldoc on IO::Socket it seems that I should be able to do the following to get the current receive buffer size:
my $rcv_buf_size = $s->sockopt($SOCKET::SO_RCVBUF);
But when I tried this $SOCKET::SO_RCVBUF is undefined. Am I doing something wrong?
It seems that the writing process gets stuck trying to write to this processes socket. How do I make the writer return immediately even if it cannot write all of the data?
Thanks in advance,
ko
