+//
+// The URLRequest class implements the V8 binding between the JavaScript API
+// and Chromium native net library. It is responsible for handling HTTP/HTTPS
+// requests.
+//
+// The current class provides only the binding layer. Two other JavaScript
+// classes (ClientRequest and IncomingMessage) in the net module provide the
+// final API, including some state management and arguments validation.
+//
+// URLRequest's methods fall into two main categories: command and event
+// methods. They are always executed on the Browser's UI thread.
+// Command methods are called directly from JavaScript code via the API defined
+// in BuildPrototype. A command method is generally implemented by forwarding
+// the call to a corresponding method on AtomURLRequest which does the
+// synchronization on the Browser IO thread. The latter then calls into Chromium
+// net library. On the other hand, net library events originate on the IO
+// thread in AtomURLRequest and are synchronized back on the UI thread, then
+// forwarded to a corresponding event method in URLRequest and then to
+// JavaScript via the EmitRequestEvent/EmitResponseEvent helpers.
+//
+// URLRequest lifetime management: we followed the Wrapper/Wrappable pattern
+// defined in native_mate. However, we augment that pattern with a pin/unpin
+// mechanism. The main reason is that we want the JS API to provide a similar
+// lifetime guarantees as the XMLHttpRequest.
+// https://xhr.spec.whatwg.org/#garbage-collection
+//
+// The primary motivation is to not garbage collect a URLInstance as long as the
+// object is emitting network events. For instance, in the following JS code
+//
+// (function() {
+//   let request = new URLRequest(...);
+//   request.on('response', (response)=>{
+//    response.on('data', (data) = > {
+//      console.log(data.toString());
+//    });
+//  });
+// })();
+//
+// we still want data to be logged even if the response/request objects are n
+// more referenced in JavaScript.
+//
+// Binding by simply following the native_mate Wrapper/Wrappable pattern will
+// delete the URLRequest object when the corresponding JS object is collected.
+// The v8 handle is a private member in WrappableBase and it is always weak,
+// there is no way to make it strong without changing native_mate.
+// The solution we implement consists of maintaining some kind of state that
+// prevents collection of JS wrappers as long as the request is emitting network
+// events. At initialization, the object is unpinned. When the request starts,
+// it is pinned. When no more events would be emitted, the object is unpinned
+// and lifetime is again managed by the standard native mate Wrapper/Wrappable
+// pattern.
+//
+// pin/unpin: are implemented by constructing/reseting a V8 strong persistent
+// handle.
+//
+// The URLRequest/AtmURLRequest interaction could have been implemented in a
+// single class. However, it implies that the resulting class lifetime will be
+// managed by two conflicting mechanisms: JavaScript garbage collection and
+// Chromium reference counting. Reasoning about lifetime issues become much
+// more complex.
+//
+// We chose to split the implementation into two classes linked via a
+// reference counted/raw pointers. A URLRequest instance is deleted if it is
+// unpinned and the corresponding JS wrapper object is garbage collected. On the
+// other hand, an AtmURLRequest instance lifetime is totally governed by
+// reference counting.
