Summary: public
Benchmarking our startup path has shown we spend a lot of time decoding strings (iPhone 4S / iPhone 5):
* reading a 2MB JS bundle: 35ms / 15ms
* decoding is to an `NSString`: 186ms / 78ms
* transforming that to a `JSString`: 29ms / 10ms
Instead of going through an `NSString` transformation, we generate a null-terminated bundle (0.1ms / 0.05ms to copy the data) and use `JSStringCreateWithUTF8CString` (121ms / 53ms) to generate the string. That makes decoding 70% faster.

This diff implements inline image support for <Text> nodes. Images are specified using <Image> tags, however all properties of the image are currently ignored apart from the source (including width/height styles).
Images are loaded asyncronously, and will trigger a text re-layout when they have loaded.

Summary: When you reload and create a new bridge, one of the things that happens during setup is that the RCTAccessibilityManager fires a notification. The old bridge would receive this notification from the new bridge's RCTAccessibilityManager, which we don't want, especially because the two are running on different shadow queues.
I believe this led to a gnarly crash in NSConcreteTextStorage because RCTMeasure in RCTShadowText.m was getting called for the old RCTText (getting destroyed) from a notification fired from the new shadow queue. The fix is for the UIManager to handle notifications only from its bridge's RCTAccessibilityManager. See #2001 for the kinds of crashes we were seeing.

Summary: This adds workarounds for the code that was preventing React from compiling when linked against an iOS App Extension target.
Some iOS APIs are unavailable to App Extensions, and Xcode's static analysis will catch attempts to use methods that have been flagged as unavailable.
React currently uses two APIs that are off limits to extensions: `[UIApplication sharedApplication]` and `[UIAlertView initWith ...]`.
This commit adds a helper function to `RCTUtils.[hm]` called `RCTRunningInAppExtension()`, which returns `YES` if, at runtime, it can be determined that we're running in an app extension (by checking whether the path to `[NSBundle mainBundle]` has the `"appex"` path extension).
It also adds a `RCTSharedApplication()` function, which will return `nil` if running in an App Extension. If running in an App, `RCTSharedApplication()` calls `sharedApplication` by calling `performSelector:` on the `UIApplication` class. This passes the static analysis check, and, in my opinion, obeys the "spirit of th

Summary:
We currently wait until after views have been updated on the main thread before sending layout events. This means that any code that relies on those events to update the UI will lag the atual layout by at least one frame.
This changes the RCTUIManager to send the event immediately after layout has occured on the shadow thread. This noticably improves the respinsiveness of the layout example in UIExplorer, which now updates the dimension labels immediately instead of waiting until after the layout animation has completed.
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:
Add JSC profiler to the dev menu and rename the pre-existent one to systrace.
For now it just outputs to the console, but a better workflow is on the way.
Summary:
Our events all follow a common pattern, so there's no good reason why the configuration should be so verbose. This diff eliminates that redundancy, and gives us the freedom to simplify the underlying mechanism in future without further churning the call sites.
Summary:
Moved the view creation & property binding logic out of RCTUIManager into a separate RCTComponentData class - this follows the pattern used with the bridge.
I've also updated the property binding to use pre-allocated blocks for setting the values, which is more efficient than the previous system that re-contructed the selectors each time it was called. This should improve view update performance significantly.
Summary:
Dynamic Text Sizes for Text component.
Text gains new prop - allowFontScaling (false by default).
There is also AccessibilityManager module that allows you to tune multipliers per each content size category.
Summary:
The bridge implementation on React Android does not currently support boxed numeric/boolean types (the equivalent of NSNumber arguments on iOS), nor does Java support Objective-C's nil messaging system that transparently casts nil to zero, false, etc for primitive types.
To avoid platform incompatibilities, we now treat all primitive arguments as non-nullable rather than silently converting NSNull -> nil -> 0/false.
We also now enforce that NSNumber * objects must be explicitly marked as `nonnull` (this restriction may be lifted in future if/when Android supports boxed numbers).
Other object types are still assumed to be nullable unless specifically annotated with `nonnull`.

Added the ability to turn on and off the network activity indicator using:

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:
These are the changes needed for full interop with the (as yet unreleased) new
version of React Devtools.
- the on-device inspector is minimized when devtools is open
- devtools highlight -> device and device touch -> devtools select works
- editing react native styles :)
Summary:

Summary:
Remove layout-only views. Works by checking properties against a list of known properties that only affect layout. The `RCTShadowView` hierarchy still has a 1:1 correlation with the JS nodes.
This works by adjusting the tags and indices in `manageChildren`. For example, if JS told us to insert tag 1 at index 0 and tag 1 is layout-only with children whose tags are 2 and 3, we adjust it so we insert tags 2 and 3 at indices 0 and 1. This keeps changes out of `RCTView` and `RCTScrollView`. In order to simplify this logic, view moves are now processed as view removals followed by additions. A move from index 0 to 1 is recorded as a removal of view at indices 0 and 1 and an insertion of tags 1 and 2 at indices 0 and 1. Of course, the remaining indices have to be offset to take account for this.
The `collapsible` attribute is a bit of a hack to force `RCTScrollView` to always have one child. This was easier than rethinking out the logic there, but we could change this later.

`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.
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/>`?)

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)

it should dispatch with a helpful message (screenshot on the comments)

the bridge modules were deallocated. That doesn't work when the bridge is held.

leave a group page. It should be called now.
Summary:

It's compatible with the js spec, with the exception that I had to add
a callback param since it's async. Also supports the same button configuration
as `AlertIOS.alert`.

Test Plan:
I've updated the `AlertIOS` example on UIExplorer with every
valid combination of
parameters, so just going through it should be fine.
