Summary:
Fixes#10433
The code didn't account for the fact that cancelLoad is set by two different threads. It gets set on the URL request queue when the request completes successfully and it gets set on the UI queue during cancelation. This oversight lead to a couple of different kinds of crashes.
1. Attempt to invoke a nil function -- We check that cancelLoad is non-nil and on the next line we call it. However, cancelLoad could have been set to nil by the other thread between the time it was verified to be non-nil and the time it was called. Consequently, the program will attempt to call nil and crash.
2. Block deallocated while it's executing -- Suppose cancelLoad points to a block, it is verified to be non-nil, and it is successfully invoked. In the middle of executing the block, cancelLoad, the last reference to the block, is set to nil. This causes the block to be deallocated and its captured values to be freed. However, the block continues executing and the next time it attempts to use a captured value

Summary:
To make React Native play nicely with our internal build infrastructure we need to properly namespace all of our header includes.
Where previously you could do `#import "RCTBridge.h"`, you must now write this as `#import <React/RCTBridge.h>`. If your xcode project still has a custom header include path, both variants will likely continue to work, but for new projects, we're defaulting the header include path to `$(BUILT_PRODUCTS_DIR)/usr/local/include`, where the React and CSSLayout targets will copy a subset of headers too. To make Xcode copy headers phase work properly, you may need to add React as an explicit dependency to your app's scheme and disable "parallelize build".

Summary:
When building a native component which takes an image reference as a prop, `resolveAssetSource` needs to be called on the image reference. If this isn't done, the native component may receive the opaque type returned by `require` (e.g. `require('./foo.png')`) which is useless to the native component. `resolveAssetSource` is used by builtin components that take image references such as `Image`, `WebView` and `MapView`.
This change makes `resolveAssetSource` public so that third-party native components can correctly handle image references.

Summary:
Here's a little background. Resizing is inferior to scaling. See http://frescolib.org/docs/resizing-rotating.html#_
Currently, React Native has a heuristic to use resize when the image is likely to be from the device's camera. However, there may be other cases where a developer wants to use resize. For example, when the developer knows they'll be downloading a large image from a service but the image will be rendered at a small size on the device.
This change adds a `resizeMethod` prop to the `Image` component so developers can choose how Fresco resizes the image. The options are 'auto', 'resize', or 'scale'. When 'auto' is specified, a heuristic is used to choose between 'resize' and 'scale'. The default value is 'auto'.
**Test plan (required)**
In a small test app, verified that the `resizeMethod` prop properly influences the mechanism that is used to resize the image (e.g. resize or scale).

Summary:
Before this PR, ```RCTImageLodaer```'s Cache was too big(200MB on disk) and It doesn't work with HTTP Cache-Control header. So to provide dynamic image, the users must have to add random value on url( ex. adding current date) to avoid cache.
So I change that cache system to default ```NSURLRequest```'s cache system, which is well-working with HTTP specs. As the discussion on this issue #7571 , making custom cache policy processor is not ready yet and useless, over-tech things, I think.
Even we have no plan about image cache system(or would change plan later), before having a nice plan, I think we should let user use image module with common HTTP Specs.
So I remove custom ```NSURLCache```, and make logic like below,
1. try fetch image,
2. on response, get ```Date``` on response's header and make ```cacheKey``` with ```Date```.

Summary:
This uses `[UIImage imageNamed:]` to load local assets that are bundled using `require('../image/path.png')` and makes sure it is done synchronously on the main queue to prevent images from flickering. This improves user experience a lot when using large local images and prevents icon flickers to match the behaviour of most native apps.
This adds to methods to the ImageLoader protocol, one to tell if the image loader must be executed on the url cache queue and one to tell if the result of the image loader should be cached. I then use these to make the LocalImageLoader bypass the url cache queue and avoid caching images twice.
Note that this doesn't affect debug builds since images are loaded from the packager.
I'm not sure if we want to still support async loading of local images as I'm not sure how much of a perf difference this will make. Maybe someone at fb can benchmark this see how it affects your apps but there wasn't a noticeable one in mine. Also I only enabled this for loading png and jpg im

If the image is larger than its frame, the image is downscaled while maintaining its aspect ratio.
That is how the Android implementation works, too.
Sorry, don't have time to write tests. 😢
Any reviewers should make sure `RCTTargetRect` returns the correct value when:
- the image is smaller than its frame (ie: no downscaling needed)
- the image is larger than its frame (should be downscaled to avoid clipping)

Hi there,
Here is a fix for #7538 (and #5085).
I had originally discovered this issue when using `resizeMode` through the style props. Although this might arguably be an incorrect usage (see https://github.com/facebook/react-native/issues/4759#issuecomment-164301166) the same issue would happen with the `tintColor` and `overlayColor` style props.
To test this, you can render the following:
```jsx
const imageContainerStyle = {width: 100, height: 100, backgroundColor: 'green', marginLeft: 10, marginTop: 10, };
const imageStyle = {flex: 1, width: undefined, height: undefined, resizeMode: 'contain', };

Summary:
This adds a new resize mode for iOS 'repeat' that tiles the image over it's frame. This allow to easily create a view with a repeating background pattern which there is no way to do at the moment without including a bunch of different sized assets.
I'm not 100% sure it should be a resizeMode or a separate prop but I went with resizeMode since it made more sense to me and the are not really any use cases where we'd want to use this with another resizeMode other than 'stretch'.
**Test plan**
Tested mainly by adding a UIExplorer example, also tested that changing the resizeMode prop from and to 'repeat' worked properly.
I'd like to implement this on Android too but it is a bit trickier since Fresco's ImageView doesn't support image tiling and would require submitting a PR there too :(

Summary:
This adds support for specifying multiple sources for an image component, so that native can choose the best one based on the flexbox-computed size of the image.
The API is as follows: the image component receives in the `source` prop an array of objects of the type `{uri, width, height}`. On the native side, the native component will wait for the layout pass to receive the width and height of the image, and then parse the array to find the best fitting one. For now, this does not support local resources, but it will be added soon.
To see how this works and play with it, there's an example called `MultipleSourcesExample` under `ImageExample` In UIExplorer.

Summary:
Under rare and as-yet-to-be determined circumstances, images can sometimes fail to load/download and get "stuck", without producing an error.
Because the `RCTNetworkTask` for these images is stuck in the "in progress" state, they clog up the RCTImageLoader task queue, which has a limit of 4 concurrent in-progress tasks.
This was previously masked by the fact that we automatically cancelled image requests when the RCTImageView moved offscreen, but we no longer do that.
This diff adds logic to detect some types of stuck task and remove them, thereby unblocking the queue. I've also restored the functionality of cancelling downloads for offscreen images (but not unloading the image itself) so that stuck images will be cancelled when you move to another screen, instead of using up space in the queue forever.

Summary:
Some apps are complaining about flashing images when performing navigation transitions. An example issue would be:
1. Load a master list view with many images
2. Click on an image to go to a detail view
3. Go back to the master list view
At step (3), users see a number of images flash from a placeholder image back to the final image because `-[RCTImageView didMoveToWindow]` calls `clearImage` when the image view exits the view hierarchy between (1) and (2) and calls `reloadImage` (which sets the image property asynchronously) when the image view re-enters the view hiearchy between (2) and (3).
This diff fixes the issue by being less aggressive about clearing image contents. It only clears image contents when the app receives a memory warning or the app goes into the background.
For comparison, CKNetworkImageComponent in ComponentKit doesn't have this purging behavior at all.

In RN we cache image data after loading/downloading an image, however the data we store is the compressed image data, and we decode this asynchronously each time it is displayed.
This can lead to a slight flicker when reloading image components because the decoded image is discarded and then re-decoded.

Summary:
This works with D3305161 to minimize image flashing. After D3305161, the completion handler passed to `-[RCTImageLoader loadImageWithoutClipping:size:scale:resizeMode:progressBlock:completionBlock:]` may be called back on the main queue in the case of a cached image. In this case, we want to set the image view's image property synchronously rather than on the next runloop iteration via dispatch_async. This minimizes the amount of image flashing the user sees when displaying a cached image.
The exception to this case is for blurred images. A blur can be an expensive (taking multiple ms on the CPU), so we always make sure to perform the blur off the main queue even if the image is cached and the callback came back on the main queue.

Summary: To prevent layout popping, when inserting images inside text we would render a blank placeholder image while the real image was loading. It turns out that this isn't necessary, as we can just specify the size of the image without having an actual image to display.

Summary:
public
React Native currently exposes the iOS layer shadow properties more-or-less directly, however there are a number of problems with this:
1) Performance when using these properties is poor by default. That's because iOS calculates the shadow by getting the exact pixel mask of the view, including any tranlucent content, and all of its subviews, which is very CPU and GPU-intensive.
2) The iOS shadow properties do not match the syntax or semantics of the CSS box-shadow standard, and are unlikely to be possible to implement on Android.
3) We don't expose the `layer.shadowPath` property, which is crucial to getting good performance out of layer shadows.
This diff solves problem number 1) by implementing a default `shadowPath` that matches the view border for views with an opaque background. This improves the performance of shadows by optimizing for the common usage case. I've also reinstated background color propagation for views which have shadow props - this should help ensure that this best-case scenario occurs more often.
For views with an explicit transparent background, the shadow will continue to work as it did before ( `shadowPath` will be left unset, and the shadow will be derived exactly from the pixels of the view and its subviews). This is the worst-case path for performance, however, so you should avoid it unless absolutely necessary. **Support for this may be disabled by default in future, or dropped altogether.**
For translucent images, it is suggested that you bake the shadow into the image itself, or use another mechanism to pre-generate the shadow. For text shadows, you should use the textShadow properties, which work cross-platform and have much better performance.
Problem number 2) will be solved in a future diff, possibly by renaming the iOS shadowXXX properties to boxShadowXXX, and changing the syntax and semantics to match the CSS standards.
Problem number 3) is now mostly moot, since we generate the shadowPath automatically. In future, we may provide an iOS-specific prop to set the path explicitly if there's a demand for more precise control of the shadow.

Summary:

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.

The +[RCTConvert UIImage:] function, while convenient, is inherently limited by being synchronous, which means that it cannot be used to load remote images, and may not be efficient for local images either. It's also unable to access the bridge, which means that it cannot take advantage of the modular image-loading pipeline.
This diff introduces a new RCTImageSource class which can be used to pass image source objects over the bridge and defer loading until later.
I've also added automatic application of the `resolveAssetSource()` function based on prop type, and fixed up the image logic in NavigatorIOS and TabBarIOS.

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

A missing return statement in RCTImageLoader meant that cached images would be loaded twice - once from cache and again from the source.

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.

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.

In ReactTextShadowNode we now look for the ReactTextInlineImageShadowNode and place a TextInlineImageSpan so that we can layout appropriately

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.
