For every call that comes from JS to Native we'd call dispatch_async so the
method would be cllead on the queue/thread it's expecting. This diff
buckets the calls by target queue, dispatches only once to that queue, and then
call all the methods for it inside the same dispatch.

Summary:
@public
`RCTDispatchEvent` and `RCTTiming` weren't being paused when there wasn't any
work left to be done.
Test Plan:
Run the timers example - check everything still works as expected
Test the ListView paging example - check scroll events are still fired as expected
Launch UIExplorer, let it idle, and put a break point on `-[RCTBridge dispatchBlock:moduleID:]`,
it should never fire.
Summary:
@public
Bridge modules were being invalidate on the main thread, what could lead to
racing conditions, move the calls to invalidate on happen to the module's
methodQueue
Test Plan: Run the tests
Summary:
@public
Add `RCT_DEV`-only profiling hooks to every method in every bridge modules to
add a little bit more detail to the timeline profile.

Summary:
This bug was causing a redbox when touching rapidly because multiple touches had the same identifier. This code was meant to ensure that a unique ID is found, but it was checking against the wrong property in the react touch array.
I don't think this was really affecting prod, because the invariant is guarded by a __DEV__ check
@public
Test Plan:
- Start several touches at once (or just rapidly jam fingers on your device), and you won't see a redbox
- Also verify that single touches, touch moves, and multi touches work as before
Summary:
The idea behind this change it to couple together menu item title
and handler. The code becomes simpler and easier to maintain, but
also makes it possible to extend dev menu in the future.
@public
Test Plan:
All menu items works as before.
Changed websocket executor class name and made sure that when the class
is missing we get nice error message.
Summary:
These two arrays aren't used. The code is easier to read without them
@public
Test Plan: Tap around UIExplorer and verify multi-touch and responder system behavior works the same
Summary:
@public
ErrorUtils.reportError is intended for reporting handled errors to the
server, like timeouts, which means that we shouldn't shove them in the
developer's face.
Test Plan: add `require('ErrorUtils').reportError(new Error('error'))` and see a useful error message with stack but no redbox. Debugger confirms `reportSoftException` is called but it doesn't do anything yet. `reportFatalError` and throwing exceptions still show redboxes.
Summary:
@public
Right now the profiler shows how long the executor took on JS but doesn't show
how long each of the batched calls took, this adds a *very* high level view of JS
execution (still doesn't show properly calls dispatched with setImmediate)
Also added a global property on JS to avoid trips to Native when profiling is
disabled.
Test Plan:
Run the Profiler on any app

On D2099270 event coalescing was implemented and the event key on the RCTSparseArray
is an uint64_t, but it was declared as NSUInteger. On a 32 bits architecture
it'll be clipped to 4 bits, meaning that just `reactTag` will be taken into
account, e.g. different types of events can coalesce with each other if they target the same view
Switching to use an NSMutableDictionary instead of RCTSparseArray and NSNumber
as keys instead of uint64_t
Test Plan: Fixed the previous tests and added a new test to RCTEventDispatcherTests
Summary:
Adds support for JS async methods and helps guide people writing native modules w.r.t. the callbacks. With this diff, on the native side you write:
```objc
RCT_EXPORT_METHOD(getValueAsync:(NSString *)key
resolver:(RCTPromiseResolver)resolve
rejecter:(RCTPromiseRejecter)reject)
{
NSError *error = nil;
id value = [_nativeDataStore valueForKey:key error:&error];
// "resolve" and "reject" are automatically defined blocks that take
// any object (nil is OK) and an NSError, respectively
if (!error) {
resolve(value);
} else {
reject(error);
}
}
```
On the JS side, you can write:
```js
var {DemoDataStore} = require('react-native').NativeModules;
DemoDataStore.getValueAsync('sample-key').then((value) => {
console.log('Got:', value);
}, (error) => {
console.error(error);
// "error" is an Error object whose message is the NSError's description.
// The NSError's code and domain are also set, and the native trace i

`RCTUIManager` would traverse the whole view hierarchy every time there was any
call from JS to Native to call `reactBridgeDidFinishTransaction` on the views
that would respond to it. This is a deprecated method that is only implemented
by 3 classes, so for now we keep track of these views as they're created and
just iterate through them on updates.
Test Plan:
> NOTE: I tested this on UIExplorer, since the internally none of the classes are used
I tried to keep it simple, so I added the following to the old code:
```
__block NSUInteger count = 0;
UIView *rootView = _viewRegistry[rootViewTag];
RCTTraverseViewNodes(rootView, ^(id<RCTViewNodeProtocol> view) {
count ++;
if ([view respondsToSelector:@selector(reactBridgeDidFinishTransaction)]) {
[view reactBridgeDidFinishTransaction];
}
});
NSLog(@"Views iterated: %zd", count);
```
The output after scrolling 20 sections of the `<ListView> - Paging` example was
```
2015-06-01 00:47:07.351 UIExplorer[67675:1709506] Views iterated: 1549
```
*every frame*
After the change
```
for (id<RCTViewNodeProtocol> node in _bridgeTransactionListeners) {
[node reactBridgeDidFinishTransaction];
}
NSLog(@"Views iterated: %zd", _bridgeTransactionListeners.count);
```
```
2015-06-01 00:51:23.715 UIExplorer[70355:1716465] Views iterated: 3
```
No matter how many pages are loaded, the output is always 3.

This fixes an issue with the containerBackgroundColor property of `<Text>` nodes, where containerBackgroundColor was being overridden by the backgroundColor. I also fixed up the example so that it demonstrates the feature more clearly.
Test Plan:
* Check UIExplorer text example
* Run Catalyst snapshot tests and check MAdMan, Groups
Test plan: broke catalyst apps

[ReactNative] Add completionBlock to -[RCTBridge enqueueJSCall:args:]
Summary:
@public
Allow to pass an optional completion block to the bridge JS calls.
The block will be called from the JS thread, after the javascript has finished
running and the returned calls have been processed/dispatched to the native modules.
Test Plan: Added `testCallbackIsCalledOnTheRightTime` to `RKBatchedBridgeTests`

Summary:
As per discussion with @nicklockwood in #875, make `RCTScrollView` check its sticky headers for hitTests first.
Closes https://github.com/facebook/react-native/pull/1415
Github Author: Brent Vatne <brent.vatne@madriska.com>
Test Plan:
Have a sticky header in a ScrollView with a Touchable onPress action, scroll a bit after it docks and try tapping, should respond to tap.
Summary:
This adds new development feature to React Native that provides information
about selected element (see the demo in Test Plan).
This is how it works:
App's root component is rendered to a container that also has a hidden layer called
`<InspectorOverlay/>`. When activated, it shows full screen view and captures all
touches. On every touch we ask UIManager to find a view for given {x,y} coordinates.
Then, we use React's internals to find corresponding React component. `setRootInstance`
is used to remember the top level component to start search from, lmk if you have a
better idea how to do this. Given a component, we can climb up its owners tree
to provice more context on how/where the component is used.
In future we could use the `hierarchy` array to inspect and print their props/state.
Known bugs and limitations:
* InspectorOverlay sometimes receives touches with incorrect coordinates (wtf)
* Not integrated with React Chrome Devtools (maybe in followup diffs)
* Doesn't work with popovers (maybe put the element inspector into an `<Overlay/>`?)

Add `RCTAssertThread` to `RCTAssert.h` for convenience when checking the current/queue,
it accepts either a `NSString *`, `NSThread *` or `dispatch_queue_t` as the object to be checked
Also add a check to `-[RCTUIManager addUIBlock:]` - There was a discussion on github (https://github.com/facebook/react-native/issues/1365)
due to the weird behavior caused by calling it from a different thread/queue (it might be added after `batchDidComplete` has been called
and will just be dispatched on the next call from JS to objc)
Test Plan:
Change `-[RCTAnimationExperimentalManager methodQueue]` to return `dispatch_get_main_queue()` and run the 2048 example,
it should dispatch with a helpful message (screenshot on the comments)
Summary:
This converts the existing JSEvaluateScript call for `require('<ModuleName>').<MethodName>.apply(null, <args>);` to native JSC C API methods which shaves off about 10-15% of invocation time on average, I used pretty primitive profiling methods to track the minimum, maximum and average invocation time so would appreciate any extra eyes on the performance.
If the argument count is zero the method is invoked directly with no arguments, if the argument count is 1 it's invoked directly with just that argument. If there is more than 1 argument then apply is used and the arguments are passed as the second parameter.
Ensured all existing tests pass and instruments leaks shows nothing is leaking.

Our background color propagation mechanism is designed to make rendering of translucent content more efficient by pre-blending against an opaque background. Currently this only works for text however, because images are not composited into their background even if the background color is opaque.
This diff precomposites network images with their background color when the background is opaque, allowing them to take advantage of this performance optimization.
I've also added some logic to correctly crop the downloaded image when the resizeMode is "cover" or "contain" - previously it was only correct for "stretch".
Before:{F22437859}
After:{F22437862}
Test Plan: Run the UIExplorer "<ListView> - Paging" example with "color blended layers" enabled and observe that the images appear in green now, instead of red as they did before.
