Fork is a very convenient way to deal with independant yet properly timed connections. It's particularly useful here for accept(), and ensures that any accepted FD will automatically be released. The principle is that when we hit a fork command, the parent restarts evaluating the actions from the beginning and the child continues to evaluate the next actions. Listen and connect are skipped if the connection is already established. Fork() is amazingly cheap on Linux, 21k forked connections per second are handled on a single core, and 38k on two cores. For now it's not possible to have two different code paths so in order to have both a listener and a connector, two distinct commands are still needed. |
