Modify request behaviour

[mStirner]

When no interface is attached (connector) its not possible to read/write from/to the upstream.
How about to attach a event listener to the interface and backpressure the request till the interface has a attached upstream/is bridged?

Pseudo code/draft (class.interface.js)

agent.createConnection = (options, cb) => {

    let input = new PassThrough();
    let output = new PassThrough();


    this.stream.pipe(input, {
        end: false
    });
    output.pipe(this.stream, {
        end: false
    });


    let socket = Duplex.from({
        readable: input,
        writable: output
    });


    // TODO implement other socket functions?!
    if (process.env.NODE_ENV !== "production") {
        socket.ref = (...args) => {
            console.log("socket.ref called", ...args);
        };
        socket.unref = (...args) => {
            console.log("socket.unref called", ...args);
        };
        socket.setKeepAlive = (...args) => {
            console.log("socket.setKeepAlive called", ...args);
        };
        socket.setTimeout = (...args) => {
            console.log("socket.setTimeout called", ...args);
        };
        socket.setNoDelay = (...args) => {
            console.log("socket.setNoDelay called", ...args);
        };
        // socket.remoteAddress=this.settings.host
        // socket.remotePort=this.settings.port
    }

    // pseude code. "attached" does not exists
    if (this.stream.attached) {
        cb(null, socket);
        return;
    }

    this.stream.once("attached", () => {
        //return socket;
        cb(null, socket);
    });

};

Does the request timeout when the callback not get called for a long time?
