Summary: public
The `bridge.modules` dictionary provides access to all native modules, but this API requires that every module is initialized in advance so that any module can be accessed.
This diff introduces a better API that will allow modules to be initialized lazily as they are needed, and deprecates `bridge.modules` (modules that use it will still work, but should be rewritten to use `bridge.moduleClasses` or `-[bridge moduleForName/Class:` instead.
The rules are now as follows:
* Any module that overrides `init` or `setBridge:` will be initialized on the main thread when the bridge is created
* Any module that implements `constantsToExport:` will be initialized later when the config is exported (the module itself will be initialized on a background queue, but `constantsToExport:` will still be called on the main thread.
* All other modules will be initialized lazily when a method is first called on them.
These rules may seem slightly arcane, but they have the advantage of not violating any assumptions that may have been made by existing code - any module written under the original assumption that it would be initialized synchronously on the main thread when the bridge is created should still function exactly the same, but modules that avoid overriding `init` or `setBridge:` will now be loaded lazily.
I've rewritten most of the standard modules to take advantage of this new lazy loading, with the following results:
Out of the 65 modules included in UIExplorer:
* 16 are initialized on the main thread when the bridge is created
* A further 8 are initialized when the config is exported to JS
* The remaining 41 will be initialized lazily on-demand

Summary: public
A missing return statement in RCTImageLoader meant that cached images would be loaded twice - once from cache and again from the source.
This was mostly innocuous, causing only a slight perf regression due to the image cache being effectively disabled, however in some cases (such as RCTImageEditingManager.cropImage) it caused the success callback to fire twice, resulting in a crash.

Summary: public
I had previously assumed (based on past experience and common wisdom) that `[UIImage imageWithData:]` was safe to call concurrently and/or off the main thread, but it seems that may not be the case (see https://github.com/AFNetworking/AFNetworking/pull/2815).
This diff replaces `[UIImage imageWithData:]` with ImageIO-based decoding wherever possible, and ensures that it is called on the main thread wherever that's not possible/convenient.
I've also serialized access to the `NSURLCache` inside `RCTImageLoader`, which was causing a separate-but-similar crash when loading images.

Summary: Hi,
I'm currently building an app that changes metadata, does some resizes, maybe watermarking ...etc. I want to use RCTImageStoreManager to store the original image in memory and allow me to command different modifications from javascript as it gives me more flexibility. As RCTImageEditingManager does for example.
But currently the RTCImageStoreManager uses UIImage to store the image, the problem is that UIImage losses metadata.
So i suggest we change it to NSData.
Additionally I added a method to remove an image from the store.

Summary: This adds the basic support for embedding an image in a TextView.
Implementation details :
We create a ReactTextInlineImageShadowNode whenever an Image is embedded within a Text context.
That uses the same parsing code as ReactImageView (copied, not shared) to parse the source property to figure out the Uri where the resource is.
In ReactTextShadowNode we now look for the ReactTextInlineImageShadowNode and place a TextInlineImageSpan so that we can layout appropriately
Later at the time we go to setText on the TextView, we update that TextInlineImageSpan so that the proper Drawable (downloaded via Fresco) can be shown

Summary: Fixes#3679, see https://github.com/facebook/react-native/issues/3679
The idea is to always load images from the same folder that we loaded JS bundle.
This doesn't change the current behavior, since `imageNamed:` inferred the
absolute path to the image from app's bundle, but now we make it explicit.
The benefit for OTA updates implementations is that they can simply ask RN
to load js from some `~/Documents/<build-id>/main.jsbundle` folder and RN will
look for images in `~/Documents/<build-id>/assets/`.
Note that for Android we will have to come out with a different plan, since
in prod we load images from built-in resources.

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.

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.

Summary: public
There was a race condition issue in RCTDownLoadTask whereby the request handler would sometimes call one of the delegate methods before setup was complete, causing an error to be logged because the request token had not been set, and causing te request to fail because the class was not yet set up.
This diff fixes that issue by adding an explicit `start` method to RCTDownloadTask, and changing the setup order to allow for the request to call back immediately without this being treated as an error.

We previously discovered that using an NSURLSessionDataTask to load local files is noticably less efficient than using regular filesystem methods.
This diff adds RCTFileRequestHandler as a replacement for RCTHTTPRequestHandler when loading local files. This reduces loading time when loading local files via XMLHttpRequest, as well as improving the performance for some image load requests.

Summary: @public
This diff unifies the logic for detecting when images refer to XCAsset files into a single function (RCTXCAssetNameForURL) and uses it for both +[RCTConvert UIImage:] and RCTImageLoader.
I've also tightened the definition of XCAssets so that it only applies to images inside .car files, not any image inside the main bundle. This avoids using the +[UIImage imageNamed:] when not strictly necessary, which is desirable since that method is not thread-safe, and has undocumented caching behavior that is difficult to reason about.

Summary: When `RCTImageView` is removed from the view hierarchy, it clears out its `image` to save memory. This makes sense, except that it gets removed from the window (view hierarchy) even when becoming the child of another view.
This fixes the logic so that it only clears out the image if the view hasn't been moved somewhere else within one frame.

Summary: @public
It's less important to reload for downscaling than upscaling, so increase the threshold in that direction. Also, this now considers each dimension separately, and a big enough change either way should result in a reload.
Finally, this considers both the current image size and the inflight target size, so we don't reload if either is already good.

This is an early release and there are several things that are known
not to work if you're porting your iOS app to Android.
See the Known Issues guide on the website.
We will work with the community to reach platform parity with iOS.
Summary:
The CameraRoll-related APIs were mixed in with the Image classes due to legacy coupling issues. Now that the APIs have been decoupled, it makes more sense for the CameraRoll classes to live in a separate library.
This will be a breaking change for apps using the CameraRoll or related APIs. Fix is to add the RCTCameraRoll lib to your project.
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.
Summary:
Currently, the system for mapping JS event handlers to blocks is quite clean on the JS side, but is clunky on the native side. The event property is passed as a boolean, which can then be checked by the native side, and if true, the native side is supposed to send an event via the event dispatcher.
This diff adds the facility to declare the property as a block instead. This means that the event side can simply call the block, and it will automatically send the event. Because the blocks for bubbling and direct events are named differently, we can also use this to generate the event registration data and get rid of the arrays of event names.
The name of the event is inferred from the property name, which means that the property for an event called "load" must be called `onLoad` or the mapping won't work. This can be optionally remapped to a different property name on the view itself if necessary, e.g.
RCT_REMAP_VIEW_PROPERTY(onLoad, loadEventBlock, RCTDirectEventBlock)
If you don't want to use this mechanism then for now it is still possible to declare the property as a BOOL instead and use the old mechanism (this approach is now deprecated however, and may eventually be removed altogether).
Summary:
require('./image.jpg') returns a number and therefore the propType is wrong. Adding it to the propType to fix the warning and dealing with flow which is completely broken for this.
