I would find it extremely useful to have a function available to a Worker
that would block and wait for a message from another Worker or from the
main thread. For example, instead of:
onmessage = function(event) {
// Do some work
// Save all state for next time
};
I'd like to have something like this:
while (true) {
var data = waitForMessage().data;
// Do some work
}
or:
var subworker = new Worker('subworker.js');
while (true) {
var data = subworker.waitForMessage().data;
// Do some work
}
A timeout would probably be nice to have. I don't have an opinion on
whether having a timeout should be optional or required.
Of course you wouldn't want to do this in the main thread, just as you
wouldn't use a synchronous XMLHttpRequest. But it's fine to have a Worker
loop indefinitely and block while waiting for results from somewhere else.
Is this a possibility?
Is there already some way to do this that I'm not aware of?
Do I need to expand on my reasons for wanting such a thing?
