// This test starts two clustered HTTP servers on the same port. It expects the
|
|||
// first cluster to succeed and the second cluster to fail with EADDRINUSE.
|
|||
//
|
|||
// The test may seem complex but most of it is plumbing that routes messages
|
|||
// from the child processes back to the supervisor. As a tree it looks something
|
|||
// like this:
|
|||
//
|
|||
// <supervisor>
|
|||
// / \
|
|||
// <master 1> <master 2>
|
|||
// / \
|
|||
// <worker 1> <worker 2>
|
|||
//
|
|||
// The first worker starts a server on a fixed port and fires a ready message
|
|||
// that is routed to the second worker. When it tries to bind, it expects to
|
|||
// see an EADDRINUSE error.
|
|||
//
|
|||
// See https://github.com/joyent/node/issues/2721 for more details.
