Martín Bigio f2438b440d Hot Loading Sourcemaps
Summary:
public

To make sourcemaps work on Hot Loading work, we'll need to be able to serve them for each module that is dynamically replaced. To do so we introduced a new parameter to the bundler, namely `entryModuleOnly` to decide whether or not to process the full dependency tree or just the module associated to the entry file. Also we need to add `//sourceMappingURL` to the HMR updates so that in case of an error the runtime retrieves the sourcemaps for the file on which an error occurred from the server.

Finally, we need to refactor a bit how we load the HMR updates into JSC. Unfortunately, if the code is eval'ed when an error is thrown, the line and column number are missing. This is a bug/missing feature in JSC. To walkaround the issue we need to eval the code on native. This adds a bit of complexity to HMR as for both platforms we'll have to have a thin module to inject code but I don't see any other alternative. when debugging this is not needed as Chrome supports sourceMappingURLs on eval'ed code

Nick Lockwood 7419a82bd7 Handle bad JSON data without crashing
Summary:
public
NSJSONSerialization throws an exception when it encounters bad JSON data, including NaN values, which may not be a programming error.

This diff adds code to catch those exceptions and convert to an error. Also, if no error handling is in place, RCTJSONStringify will now display a redbox, and attempt to recover by sanitizing the JSON data and retrying.

Nick Lockwood 060664fd3d Refactored module access to allow for lazy loading
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

Martin Kralik c324286fb7 truncate redbox error
Summary: If a redbox error is too long it's not shown at all:
{F24443416}
This diff truncates it to its first 10000 chars, which should be good enough:
{F24443417}

The reason is a limitation of UILabel which backs text property on the used UITableViewCell.
Ideally we would use a custom cell with UITextView, but I don't feel there is any value in displaying super long error messages in a redbox.

Yusef Napora 2f9bd1f62f App Extension support
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
