// Rules:
|
|
//
|
|
// - Do not throw from handle methods. Set errno.
|
|
//
|
|
// - MakeCallback may only be made directly off the event loop.
|
|
// That is there can be no JavaScript stack frames underneith it.
|
|
// (Is there anyway to assert that?)
|
|
//
|
|
// - No use of v8::WeakReferenceCallback. The close callback signifies that
|
|
// we're done with a handle - external resources can be freed.
|
|
//
|
|
// - Reusable?
|
|
//
|
|
// - The uv_close_cb is used to free the c++ object. The close callback
|
|
// is not made into javascript land.
|
|
//
|
|
// - uv_ref, uv_unref counts are managed at this layer to avoid needless
|
|
// js/c++ boundary crossing. At the javascript layer that should all be
|
|
// taken care of.
