-
-//
-// 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.
