POE::Component::IKC::Server - POE Inter-kernel Communication server
use POE; use POE::Component::IKC::Server; create_ikc_server( ip=>$ip, port=>$port, name=>'Server',); ... $poe_kernel->run();
This module implements a POE IKC server. A IKC server listens for incoming connections from IKC clients. When a client connects, it negociates certain connection parameters. After this, the POE server and client are pretty much identical.
This function initiates all the work of building the IKC server. Parameters are :
Address to listen on. Can be a doted-quad ('127.0.0.1') or a host name ('foo.pied.nu'). Defaults to '0.0.0.0', aka INADDR_ANY.
Port to listen on. Can be numeric (80) or a service ('http').
Path to the unix-socket to listen on. Note: this path is unlinked before socket is attempted! Buyer beware.
Local kernel name. This is how we shall "advertise" ourself to foreign kernels. It acts as a "kernel alias". This parameter is temporary, pending the addition of true kernel names in the POE core. This name, and all aliases will be registered with the responder so that you can post to them as if they were remote.
Arrayref of even more aliases for this kernel. Fun Fun Fun!
Print extra information to STDERR if true. This allows you to see what is going on and potentially trace down problems and stuff.
Activates the pre-forking server code. If set to a positive value, IKC will fork processes-1 children. IKC requests are only serviced by the children. Default is 1 (ie, no forking).
Time, in seconds, between invocations of the babysitter event.
Number of connections a child will accept before exiting. Currently, connections are serviced concurrently, because there's no way to know when we have finished a request. Defaults to 1 (ie, one connection per child).
This event causes the server to close it's socket, clean up the shop and head home. Normally it is only posted from IKC::Responder.
Preforking is something of a hack. In particular, you must make sure that your sessions will permit children exiting. This means, if you have a delay()-loop, or event loop, children will not exit. Once POE gets multicast events, I'll change this behaviour.
