Kevin Gozali 150fe7cb9c fixed polyfill for BackAndroid
Summary:
`BackAndroid.addEventListener()` returns a subscription object with a `remove()` function in android. Before this fix, the iOS equivalent doesn't return anything, which means, if there's a component doing something like this, it would redbox:

```
componentWillMount() {
  this._subscription = BackAndroid.addEventListener('hardwareBackPress', () => {...});
}

componentWillUnmount() {
  this._subscription.remove(); // --> redbox in iOS before this fix
}

Adam Comella 5d748b2eec Fix memory leak in MessageQueue
Summary:
The MessageQueue has a _debugInfo object where it stores debug information associated with each callback. The size of this structure is currently unbounded.

It looks like the code attempted to restrict _debugInfo to a fixed number of entries but due to a logic bug, it leaked around 30 entries for every 1 entry it cleaned up.

This change limits the _debugInfo object to around 30 entries.

**Test plan (required)**

This change is currently being used in my team's app.

Dan Abramov 1aef7e4629 Update hook event names
Summary:
This brings RN up to date with https://github.com/facebook/react/pull/7472 (scheduled for React 15.3.1).
If you use React 15.3.1 with RN without this patch, Systrace output will lack the reconciler events.

(Since it’s a niche feature it didn’t seem to me that full backward compat is necessary so I just removed old hooks. This won’t cause crashes—it’s just you won’t get events in Systrace if you use new React but old RN.)

Rickard Ekman 8e2906ae89 Android: Implement cancelable option for Alerts
Summary:
**Motivation**
In iOS you cannot dismiss alerts by clicking outside of their box, while on Android you can. This can create some inconsistency if you want to have identical behavior on both platforms. This change makes it possible for Android apps to have irremovable/required alert boxes just like in iOS.

This adds an additional parameter to the Alert method. The way to use it is by providing an object with the cancelable property. The cancelable property accepts a boolean value.

This utilizes the Android DialogFragment method [setCancelable](https://developer.android.com/reference/android/app/DialogFragment.html#setCancelable(boolean))

**Usage example**
```js
Alert.alert(
   'Alert Title',
   null,
   [
     {text: 'OK', onPress: () => console.log('OK Pressed!')},
   ],
   {
     cancelable: false
   }
);
```

**Test plan (required)**

I added an additional alert to the UIExplorer project where it can be tested. I also added a part in the Dialog Module test to make sure setting canc

Dotan Nahum 77e48f1782 Make MessageQueue to emit "SPY" events in a way that can be extensible
Summary:
This PR adds a capability for MessageQueue to emit "SPY" events in a way that can be extensible, to later allow for a tooling ecosystem to grow, one example is the existing [Snoopy](https://github.com/jondot/rn-snoopy) tool that is, for now, forced to work with monkeypatches, and after this PR will be able to use a "formal" way to trace queue events.

After this change, we can wire a "spy" into a queue that will expose the events in different and interesting ways, see below (done with Snoopy):

Summary:
This diff enables network inspection for WebSocket APIs, so by now XMLHttpRequest, Fetch and WebSocket are all supported. Android and iOS are both supported.

This diff monkey-patches the RCTWebSocketModule which WebSocket API builds on, and now it is able to intercept all WebSocket requests when app is running. The intercepted information of a WebSocket includes url, protocols, status, messages (sent and received), close reason, server close event and server error information, etc.

Siqi Liu f20d5ed67f Intercept XMLHttpRequest network operations and gather their information in inspector tool
Summary:
This diff
- creates `XHRInterceptor` to intercept all XMLHttpRequest network operations in React Native by monkey-patching.
- enables `XHRInterceptor` in RN development tool "inspector".

This interception and inspector tool work well on both Android and iOS. And this supports interception on any network API based on XMLHttpRequest, especially the Fetch API.

By now, we can intercept 12 information fields of a XMLHttpRequest including method, url, data sent, status, response type, response size, requestHeaders, responseHeaders, response, responseURL, responseType and timeout.

Follow-up:
- Will add UIs in the inspector on top of this diff, to display all the network operation information. (Not in this diff just to make this shorter)
- Will extend this to gather other valuable information towards one XMLHttpRequest.
- Should support other network request APIs like WebSocket.

* Make the bridge config configurable so that when we disable automocking and we reset the registry we can redefine the value.

Oh also, stop using lodash in Server.js. First off, lodash 3 doesn't work in Jest's node env because it does some crazy stuff, second because we don't need to load all of lodash for debounce.

Leon 57d85f1c3e Fixing Syntax Error "errorMessage" is read-only
Summary:
Changed const to let, to dodge the following issue:

> "errorMessage" is read-only
>   203 |         const errorMessage = `Callback with id ${cbID}: ${module}.${method}() not found`;
>   204 |         if (method) {
> > 205 |           errorMessage = `The callback ${method}() exists in module ${module}, `
>       |           ^
>   206 |           + `but only one callback may be registered to a function in a native module.`;
>   207 |         }

Christine Abernathy 22f59a88a6 Improve autogen for reference docs including jsdoc support
Summary:
As part of improving the API and Component reference docs #8154 this pull request adds the following:

- jsdoc support for API docs. See the AlertIOS changes as an example.
- type definitions support and added to both API and Component docs. This is supported via react-docgen and jsdoc.
- better formatting of method properties (now shown in a table).

FYI, API and Component docs were previously generated in two different ways. Components were using react-docgen and that basically remains as-is. APIs were using custom parsing code and that's been switched to use a jsdoc parser + react-docgen as an option for typedefs (it could also use the jsdoc parser).

Two docs have been updated to showcase how we'd like the new docs to look:

- AlertIOS (API): showing method parameters, examples, typedefs, more details overall.
- Statusbar (Component): showing method parameters, typedefs, more details overall.

**Note**: To convert new API docs to use the new format, add `jsdoc` to the initial file comment. C

Satyajit Sahoo 803cb61346 Show better error message when accessing React APIs on React Native
Summary:
**Motivation:**

Lots of examples on the web still have the old way to import React APIs from React Native. Also when someone upgrades to latest version of React Native without reading the release notes can get confused. This PR adds getters for  `createClass` and `Component` and throws an error with a better error message when they are accessed.

![screenshot_20160614-125622](https://cloud.githubusercontent.com/assets/1174278/16034600/47c70222-3230-11e6-9fe4-1a3493708829.png)

**Test plan:**

Trying to use `ReactNative.createClass` or `ReactNative.Component` will throw an error with this error message.

There's currently a bug in `symbolicateStackTrace` which actually crashes the app after showing the error due to the `stack` being null when updating the stack trace. But that's a separate issue which should be fixed separately. For now, to prevent the crash, we need to add the following before the return statement here - https://github.com/facebook/react-native/blob/master/Libraries/JavaScriptAppEn
