+possible with your report. If you can, please include:
+  * The version of Electron you are using

-### Issue Closure
 
-Bug reports will be closed if the issue has been inactive and the latest affected version no longer receives support. At the moment, Electron maintains its three latest major versions, with a new major version being released every 12 weeks. (For more information on Electron's release cadence, see [this blog post](https://electronjs.org/blog/12-week-cadence).)
+## Submitting Pull Requests
 
-_If an issue has been closed and you still feel it's relevant, feel free to ping a maintainer or add a comment!_

+  See the [Documentation Styleguide](/docs/styleguide.md).
+* Use short, present tense commit messages. See [Commit Message Styleguide](#git-commit-messages).

+## Styleguides
 
-We accept issues in *any* language.
-When an issue is posted in a language besides English, it is acceptable and encouraged to post an English-translated copy as a reply. 
-Anyone may post the translated reply.
-In most cases, a quick pass through translation software is sufficient.
-Having the original text _as well as_ the translation can help mitigate translation errors.
+### General Code
 
-Responses to posted issues may or may not be in the original language.
+* End files with a newline.
+* Place requires in the following order:
+  * Built in Node Modules (such as `path`)
+  * Built in Electron Modules (such as `ipc`, `app`)
+  * Local Modules (using relative paths)
+* Place class properties in the following order:
+  * Class methods and properties (methods starting with a `@`)
+  * Instance methods and properties
+* Avoid platform-dependent code:
+  * Use `path.join()` to concatenate filenames.
+  * Use `os.tmpdir()` rather than `/tmp` when you need to reference the
+    temporary directory.
+* Using a plain `return` when returning explicitly at the end of a function.
+  * Not `return null`, `return undefined`, `null`, or `undefined`

+
+//
+// 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.
