Top Forums Programming Client accidently close when the server crash Post 302521876 by Loic Domaigne on Thursday 12th of May 2011 03:14:09 PM

I'm glad that I won't end-up maintaining your code...

I played with it a bit, took me some time to get the client working without crash:

- A Pthread_attr_init is missing for rx (Client.c:218)

- Your client must be aware that a server may close the TCP connection brutally (RST segment). In this case, you'll get 0 on read() or SIGPIPE on the next write(). The way you usually get around this is to ignore SIGPIPE and watch for errno EPIPE when write() fails.

- There is likely more problems with your code.

HTH, Loïc

NAME
Net::SMTP::Server::Client - Client session handling for Net::SMTP::Server. SYNOPSIS
use Carp; use Net::SMTP::Server; use Net::SMTP::Server::Client; use Net::SMTP::Server::Relay; $server = new Net::SMTP::Server('localhost', 25) || croak("Unable to handle client connection: $! "); while($conn = $server->accept()) { # We can perform all sorts of checks here for spammers, ACLs, # and other useful stuff to check on a connection. # Handle the client's connection and spawn off a new parser. # This can/should be a fork() or a new thread, # but for simplicity... my $client = new Net::SMTP::Server::Client($conn) || croak("Unable to handle client connection: $! "); # Process the client. This command will block until # the connecting client completes the SMTP transaction. $client->process || next; # In this simple server, we're just relaying everything # to a server. If a real server were implemented, you # could save email to a file, or perform various other # actions on it here. my $relay = new Net::SMTP::Server::Relay($client->{FROM}, $client->{TO}, $client->{MSG}); } DESCRIPTION
The Net::SMTP::Server::Client module implements all the session handling required for a Net::SMTP::Server::Client connection. The above example demonstrates how to use Net::SMTP::Server::Client with Net::SMTP::Server to handle SMTP connections. $client = new Net::SMTP::Server::Client($conn) Net::SMTP::Server::Client accepts one argument that must be a handle to a connection that will be used for communication. Once you have a new client session, simply call: $client->process This processes an SMTP transaction. THIS MAY APPEAR TO HANG -- ESPECIALLY IF THERE IS A LARGE AMOUNT OF DATA BEING SENT. Once this method returns, the server will have processed an entire SMTP transaction, and is ready to continue. Once $client->process returns, various fields have been filled in. Those are: $client->{TO} -- This is an array containing the intended recipients for this message. There may be multiple recipients for any given message. $client->{FROM} -- This is the sender of the given message. $client->{MSG} -- The actual message data. :) AUTHOR AND COPYRIGHT Net::SMTP::Server / SMTP::Server is Copyright(C) 1999, MacGyver (aka Habeeb J.
