Summary:
While adeveloper requests the emitter to emit an event, the emitter
may not emit the event immediately instead of putting the request
into a queue and process it later.
This diff allows the developer to provide a callback which will be called
when the event has been emitted.
For instance:
```
class NavigationContext {
push(nextRoute) {
var nextStack = this._stack.push(nextRoute);
this.emit(
'change',
{
reason: 'push',
nextStack: nextStack,
nextRoute: nextRoute,
},
this._onPush
);
}
_onPush(event){
if (event.defaultPrevented) {
return;
}
this._stack = event.nextStack;
this.emit('change');
}
}
```
Summary:
`NSProcessInfo operatingSystemVersion` was being used to check the system version
for the Legacy Profiler on `RCTContextExecutor` but it's only available on iOS8+
Change it to `[UIDevice systemVersion]`
Summary:
Because we don't want to integrate Animated inside of the core of React, we can only pass Animated.Value to styles of <Animated.View>. TouchableOpacity unfortunately used cloneElement. This means that we should have asked every single call site to replace their children to Animated.View. This isn't great.
The other solution is to stop using cloneElement and instead wrap the children inside of an <Animated.View>. This has many advantages:
- We no longer use cloneElement so we're no longer messing up with elements that are not our own.
- Refs are now working correctly for children elements
- No longer need to enforce that there's only one child and that this child is a native element
The downside is that we're introducing a <View> into the hierarchy. Sadly with CSS there is no way to have a View that doesn't affect layout. What we need to do is to remove the inner <View> and transfer all the styles to the TouchableOpacity. It is annoying but fortunately a pretty mechanical process.
I think that having a wrapper is the best solution. I will investigate to see if we can make wrappers on TouchableHighliht and TouchableWithoutFeedback as well.
**Upgrade Path:**
If the child is a View, move the style of the View to TouchableOpacity and remove the View itself.
```
<TouchableOpacity onPress={...}>
<View style={...}>
...
</View>
</TouchableOpacity>
-->
<TouchableOpacity onPress={...} style={...}>
...
</TouchableOpacity>
```
If the child is an Image or Text, on all the examples at Facebook it worked without any change. But it is a great idea to double check them anyway.
Summary:
React Native will now use JSONKit if it's already available in the project, otherwise it will fall back to using NSJSONSerialization as before. This provides a small performance boost to JSON parsing in some cases.
Summary:
The context wasn't being explicitly released before, since it'd be immediately
released. Now that the executors are bridge modules, it was only being deallocated
when the modules were released, what caused the threads to not be released at all.
Summary:
idStack is going away soon. This removes all references to it. Looking at the internal state of navigator will make you have a bad time.
The biggest change is switching to the new component-freezing techinique in the navigation bars. This way we avoid dependence on the idStack to provide a scalar ID for each route.
Summary:
dispatch_semaphore_wait with DISPATCH_TIME_NOW don't wait for the semaphore. It just test whether there's a signal and return the result.
So the line "dispatch_semaphore_wait(semaphore, DISPATCH_TIME_NOW);" does nothing here. It seems like a bug, but each executing in js thread will be queued, so it's safe to remove the unused semaphore instead of wait for it.

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.)
Summary:
Added Gzip function to RCTUtils. This uses dlopen to load the zlib library at runtime so there's no need to link it into your project.
The main reason for this feature is to support gzipping of HTTP request bodies. Now, if you add 'Content-Encoding:gzip' to your request headers when using XMLHttpRequest, your request body will be automatically gzipped on the native side before sending.
(Note: Gzip decoding of *response* bodies is handled automatically by iOS, and was already available).
Summary:
By default, the edges of rotated layers on iOS have jagged edges because they are not antialiased. Setting `allowsEdgeAntialiasing` makes them look a lot nicer by smoothing out the jaggies. This is particularly important for UIs like Tinder cards, for example.

Summary:
Infinite scrolling in horizontal ListViews. Rather than just using height and Y offset to determine when to load more rows, it checks `props.horizontal` and switches between width/height and offset X/Y accordingly.
This changed required some renaming. However, the only change external to `ListView.js` is exporting `contentSize` instead of `contentHeight` from the `getMetrics()` function. (This is not part of the API, but is used "for perf investigations or analytics" and isn't reference in the repo).
I believe this change works as expected (and the xcode tests pass) though it's possible that there may more complexity in this issue that I have overlooked.

Summary:
Clicking on a TextField with editable set to false still would trigger a keyboard event.
In this case that the TextField was a multiline, it would scroll you down to the bottom.

When developing against master I want to rely on the version numbers being reasonably accurate.

Summary:
Remove `RCTGetExecutorID` and `RCTSetExecutorID`, it wasn't used anymore since
the bridge was refactored into `RCTBridge` and `RCTBatchedBridge`.
Summary:
Every once in a while a guard is forgotten somewhere and the redbox is gone. I
want to remove the guards, but for that the stack traces have to be symbolicated
on the native side. So for now it just adds yet another check, in case a guard
is missing on JS.
Summary:
onItemRef is old and no longer needed now that the parent renders the scenes. This removes it from Navigator and all of our clients.
This is a breaking change to users of Navigator, but it is easy to transition to a ref in renderScene instead
