Nick Lockwood 748a507861 Simplified Image.js
Summary:
Now that we no longer have a separate NetworkImageView implementation, we can remove that code path from Image.js

I've also moved the prefetch method into RCTImageViewManager for consistency with the getImageSize method, which means we no longer need to export the RCTImageLoader module to js.

Adam Comella ee8496f364 iOS: Support HTTP headers for source prop on <Image> components
Summary:
Allows developers to specify headers to include in the HTTP request
when fetching a remote image. For example, one might leverage this
when fetching an image from an endpoint that requires authentication:

```
<Image
  style={styles.logo}
  source={{
    uri: 'http://facebook.github.io/react/img/logo_og.png',
    headers: {
      Authorization: 'someAuthToken'
    }
  }}
/>
```

Note that the header values must be strings.

Works on iOS and Android.

**Test plan (required)**

- Ran a small example like the one above on iOS and Android and ensured the headers were sent to the server.
- Ran a small example to ensure that \<Image\> components without headers still work.
- Currently using this code in our app.

Nick Lockwood dc13115445 Dispatch module setup asynchronously to avoid blocking main thread when bridge starts
Summary:Initializing native modules can block the main thread for tens of milliseconds when it starts up, making it difficult to instantiate the bridge on demand without causing a performance blip.

This diff splits up the initialization of modules so that - although they still happen on the main thread - they don't block the thread continuously.

Nick Lockwood 21fcbbc32c Generalized image decoding and resizing logic
Summary:
public

Standardises the image decoding logic for all image sources, meaning we get the benefits of efficient downscaling of images from all sources, not just ALAssets.

Nick Lockwood 718cd7953f Added getImageSize method
Summary:
public

This diff adds a `getSize()` method to `Image` to retrieve the width and height of an image prior to displaying it. This is useful when working with images from uncontrolled sources, and has been a much-requested feature.

In order to retrieve the image dimensions, the image may first need to be loaded or downloaded, after which it will be cached. This means that in principle you could use this method to preload images, however it is not optimized for that purpose, and may in future be implemented in a way that does not fully load/download the image data.

A fully supported way to preload images will be provided in a future diff.

The API (separate success and failure callbacks) is far from ideal, but until we agree on a unified standard, this was the most conventional way I could think of to implement it. If it returned a promise or something similar, it would be unique among all such APIS in the framework.

Please note that this has been a long time coming, in part due to much bikeshedding about what the API should look like, so while it's not unlikely that the API may change in future, I think having *some* way to do this is better than waiting until we can define the "perfect" way.

Nick Lockwood 1d6d1189f0 Improved threading for image loader
Summary: public

The image loader was previously returning on the main thread, which could lead to poor performance due to various call sites doing further image processing (resizing, cropping, etc.) directly in the completion block.

This diff modifies the loader to return on a background thread (the same one used to load the image), and updates the call sites to dispatch to the explicit thread they need.

Nick Lockwood 1076f4a172 Added RCTDataRequestHandler
Summary: public

Added RCTDataRequestHandler, which is responsible for loading data URLs. This moves the logic for data URL handling out of RCTImageDownloader (no longer needed) and into the RCTNetwork library, where it makes more sense.

This also means that it is now possible to load data URLs via XHR, and use them for purposes other than just images.

Nick Lockwood e4110456ab Changed RCTImageLoader to always return a UIImage
Summary:
GIF images are currently loaded as a CAKeyframeAnimation, however returning this animation directly from RCTImageLoader was dangerous, as any code that expected a UIImage would crash.

This diff changes RCTGIFImageLoader to return a UIImage of the first frame, with the keyframe animation attached as an associated object. This way, code that is not expecting an animation will still work correctly.

Nick Lockwood 61c648d564 Merged RCTNetworkImageView functionality into RCTStaticImage
Summary:
RCTNetworkImageView and RCTStaticImage had significant overlap in functionality, but each had a different subset of features and bugs.

This diff merges most of the functionality of RCTNetworkImageView into RCTStaticImage, eliminating some bugs in the former, such as constant redrawing when properties were changed.

I've also removed the onLoadAbort event for now (as it wasn't implemented), and renamed the other events to match the web specs for `<img>` and XHMLHttpRequest. The API is essentially what Adobe proposed here: http://blogs.adobe.com/webplatform/2012/01/13/html5-image-progress-events/

The following features have not yet been ported from RCTNetworkImageView:

- Background color compositing. It's not clear that this adds much value and it increases memory consumption, etc.
- Image request cancelling when images are removed from view. Again, it's not clear if this is a huge benefit, but if it is it should be combined with other optimisations, such as unloading offscreen images.

(Note that this only affects the open source fork. For now, internal apps will still use FBNetworkImageView for remote images.)

Nick Lockwood f88bc3eb73 [ReactNative] Refactor RCTDataManager to support pluggable data source modules (RCTURLRequestHandlers)
Summary:
@public

This is a refactor of @philikon's original diff that decouples the dependencies between the Network and Image modules, and replaces RCTDataQueryExecutor with a more useful abstraction.

I've introduced the RCTURLRequestHandler protocol, which is a new type of bridge module used for loading data using an NSURLRequest. RCTURLRequestHandlers can be registered using RCT_EXPORT_MODULE() and are then available at runtime for use by the RCTDataManager, which will automatically select the appropriate handler for a given request based on the handler's self-reported capabilities.

The currently implemented handlers are:

- RCTHTTPRequestHandler - the standard open source HTTP request handler that uses NSURLSession
- RKHTTPRequestHandler - the internal FB HTTP request handler that uses FBNetworking
- RCTImageRequestHandler - a handler for loading local images from the iOS asset-library

Depends on D2108193

Test Plan:
- Internal apps still work
- OSS port still compiles, Movies app and a sample Parse app still work
- uploading image to Parse using the above code snippet works
- tested `FormData` with string and image parameters using http://www.posttestserver.com/

Summary:
With this in place, it's possible to upload a picture from the `CameraRoll` to Parse, for instance:

    xhr = new XMLHttpRequest();
    xhr.onload = function() {
      data = JSON.parse(xhr.responseText);
      var parseFile = new Parse.File(data.name);
      parseFile._url = data.url;
      callback(parseFile);
    };
    xhr.setRequestHeader('X-Parse-Application-Id', appID);
    xhr.setRequestHeader('X-Parse-JavaScript-Key', appKey);
    xhr.open('POST', 'https://api.parse.com/1/files/image.jpg');
    // assetURI as provided e.g. by the CameraRoll API
    xhr.send(new NativeFile(assetURI));
