Summary:
Check in the `process.env.NODE_ENV` inline plugin. This will be used in conjuction with uglifyjs to eliminate dead code resulting from environment checks.
Summary:
Instead of using plain objects and having to convert to and from them we just use the `Module` class across the codebase.
This seems cleaner and can enforce the type as opposed to fuzzy objects.
Summary:
We're hitting an issue with large code size and `Maximum call stack size exceeded` error. https://github.com/mishoo/UglifyJS2/issues/414
We're seeing on inconsistently failing on landcastle.
Summary:
Introduce a Bundler capable of generating the layout of modules for a given entry point. The current algorithm is the most trivial we could come up with: (1)it puts all the sync dependencies into the same bundle and (2) each group of async dependencies with all their dependencies into a separate bundle. For async dependencies we do this recursivelly, meaning that async dependencies could have async dependencies which will end up on separate bundles as well.
The output of of the layout is an array of bundles. Each bundle is just an array for now with the dependencies in the order the requires where processed. Using this information we should be able to generate the actual bundles by using the `/path/to/entry/point.bundle` endpoint. We might change the structure of this json in the future, for instance to account for parent/child bundles relationships.
The next step will be to improve this algorithm to avoid repeating quite a bit dependencies across bundles.
Summary:
This freezes the app in the UIExplorer because we try to push a new view controller onto the screen before the navigator finishes loading. This was exacerbated by @tadeuzagallo's diff that made the loading even faster. Hehe
Summary:
This diff removes calls to `-updateClippedSubviews` by only re-clipping when the scroll view moves by a certain number of pixels.
leeway = 50pt => 46.9% of calls removed
leeway = 10pt => 13.2% " " "
Summary:
With a multiline TextInput, the text is initially rendered correctly but once you try to edit it, the cursor slides off the top of the view and out of its bounds. Also if the TextInput is scrollable, you can scroll the text out of the bounds of the view, which looks buggy unless you clip the overflow. This occurs because the top content inset is applied to the RCTTextView instead of the UITextView's text container.
This diff fixes both bugs by applying the vertical insets to the UITextView's textContainerInset instead of the RCTTextView's frame (which is a wrapper around a real UITextView).
The left inset is still applied to the frame because there is a bug with the text rendering when the left textContainerInset is negative: the initial text doesn't show up until you focus the text view. The bug doesn't occur when setting the right textContainerInset, so I apply this workaround to only the left inset.

Summary:
This is the first step to add support for splitting the JS bundle into multiple ones. This diff adds support for keeping track of the async dependencies each module has. To do so we introduce the following syntax:
require.ensure(['dep1', 'dep2, ..., 'depN'], callback);
Where the callback function is asynchronously invoked once all the indicated modules are loaded.
Internally, the packager keeps track of every set of async dependencies a module has. So for instance if a module looks like this:
require.ensure(['dep1'], () => {...});
require.ensure(['dep2'], () => {...});
the `Module` object will keep track of each set of dependencies separately (because we might want to put them on separate bundles).
Summary:
The word Package is overloaded, it may mean npm package, or may mean a collection of bundles. Neither is what we mean. We mean `bundle`.
This renames it and modernize some of the Bundler code.
Summary:
stacktrace-parser used to list only Node 0.10 under its list of supported engines. This new version includes Node 1.x and 2.x (i.e. io.js) as well, which addresses the warning during `npm install`.
There's no problem with using the older version of stacktrace-parser; this just clears the warning.

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.

Addresses #1534
When an image has a known width, but a height of 0 (which can happen if `flex: 1` is set on the `Image` element), `RCTDownloadManager` attempts to scale it to an invalid size, which results in a `NULL` `CGContextRef` and some scary warnings from UIKit:
```
<Error>: CGContextTranslateCTM: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update.
```
This adds a check for zero width or height to the `RCTClipRect` function. If either dimension is zero, it is calculated based on the aspect ratio of the source image. This ensures that we don't try to create an invalid `CGContextRef`, and that images with an unknown dimension are still scaled, blended, etc.

Summary:
In the latest 0.9.0-rc of React Native, the default image won't load due to a typo and a missing condition in `setImage`. This PR contains fixes for both of them.

Summary:
The cache is only used for JSTransformer at the moment. We're doing IO and some computation to get each module's name, whether is a haste or node module and it's dependencies. This work happens on startup so by caching this value we shouldbe able to reduce the start up time. Lets promote the Cache to the Packager level to be able to use it by any of the components of the packager. For now, on this diff we'll start using it to cache the mentioned fields.
Also we had to introduce the concept of fields in the cache as manually merging the date we had for each path is not possible as we're using promisses all around. With the new API, each field is a promise.
@amasad and I did some manual testing to measure the impact of this change and looks like it's saves 1 second when building the haste map (which represents 50% of the time). Overall this reduces 1 second of start up time which was currently about 8s on my mac book pro.
