Summary:
A blog post with notes from the first React Native monthly meeting.
I've gathered notes after the meeting in this blog post. Think it might be useful for a broader audience in React Native community.
No test plan, submitting just a documentation file.

Summary:
After execution of `scripts/ios-install-third-party.sh` a symlink is created :
`<YOUR-APP-PATH>/node_modules/react-native/third-party/glog-0.3.4/test-driver`
that is pointing to `test-driver -> /usr/share/automake-1.14/test-driver`
This can be executed indirectly by `react-native run-ios`.
This breaks the bundle process if the system don't contain a given file under the link and having this strict dependency on the system setup is not a good practice.
Once the `test-driver` symlink is created android app release is failing, for :
`./gradlew assembleRelease`
the `:app:bundleReleaseJsAndAssets` returns :
```
FAILURE: Build failed with an exception.
* What went wrong:
Could not list contents of '<YOUR-APP-PATH>/node_modules/react-native/third-party/glog-0.3.4/test-driver'. Couldn't follow symbolic link.
```

1. Create new project with `react-native init <YOUR-APP>`
2. cd `<YOUR-APP>/`
3. Run app on iOS `react-native run-ios` so `scripts/ios-install-third-party.sh` is executed.
4. cd `android/`
5. Run android app release `./gradlew assembleRelease` (it will work properly after this fix and fail if the `test-driver` symlink exists)
IMHO we should resolve the issue with this quick fix and apply the proper fix later after the new version of `google/glog` will be released.
The proper cleanup of files generated by autotools was already applied : https://github.com/google/glog/pull/188

Summary:
I encountered an issue when building with fastlane gym / xcodebuild where glog would not build because of missing config.h header file. I tracked it down to the ios-configure-glog.sh script that ended up error-ing because of missing valid c compiler. I guess it didn't enter the if to set c compiler env in xcodebuild and that env doesn't have proper values set like it does in xcode so just removing this check fixed it. Also tested that it still works properly in xcode.

Summary:
That's interesting!
If we apply `display: none;` style to some node, Yoga will stop calculation layout for this subtree (which is reasonable).
So, from RN perspective we have to stop applying layout for hidden subtree because it is meaningless and causes another errors.
Note: We do actually not support `display: none;` yet. It stops computing layout, but it does not hide the views!

Summary:
Returning an object that doesn't have all the required properties from `getItemLayout` doesn't cause a flow error (maybe because we are using `createAnimatedComponent`) and caused ALL items to be rendered which caused perf issues that were hard to debug (typo lenght -> length -_-). This adds a simple warning in DEV mode using checkPropTypes.
**Test plan**
Tested in RNTester by passing a bad `getItemLayout` function.

Summary:
Subview clipping still causes issues on Android and would be pretty hard to fix properly, I investigated this a bit and sticky header views are getting removed because it doesn't take transform into consideration. It would also require to recalculate subview clipping on every transform change so I think it is better to just disable subview clipping in when there are sticky headers, especially since we seem to be moving away from subview clipping with things like FlatList.
**Test plan**
Tested that sticky headers work in ListView paging example.

Summary:
Curently FlatList does not implement setting native props directly like the old ListView did. This pr introduce the `setNativeProps` function which delegates to MetroListView or VirtualizedList. Thos don't have `setNativeProps` handling either, so, I delegated further to the respective ListView and Scroll components, which do have handling for it, thus, allowing to set the native props through FlatList.
Create a project with a FlatList and change a native property using `setNativeProps`:
```javascript
componentDidMount() {
setInterval(() => {
this.list.setNativeProps({ style: {backgroundColor:"white"} })
}, 1000)
}
render() {
return (
<View style={styles.container}>
<FlatList ref={component => this.list = component}
style={{backgroundColor:"black"}}
data={[{key: 'a'}, {key: 'b'}]}
renderItem={({item}) => <Text>{item.key}</Text>} />
</View>
)
}
```

_What existing problem does the pull request solve?
In iOS when sending a silent push notification you need to configure the 'content-available' APS key to the value of 1 (When this key is present, the system wakes up your app in the background and delivers the notification to its app delegate, see [apple docs](https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/PayloadKeyReference.html#//apple_ref/doc/uid/TP40008194-CH17-SW1)).
This PR exposes this property to the notification event handler so app code can handle silent push scenario specifically. Currently this property is not available.
I've updated the PushNotificationIOSExample in the RNTester.
1. Open RNTester in xcode
2. Enable the push notifications capability
3. run on device
4. Go to PushNotificationIOS
5. click on "send fake notification"
6. verify alert message contains 'content-available' with a value of 1.

Summary:
When rendering a large list without a getItemLayout (ie SectionList, where it's hard to compute), it freaks out and attempt to render them all, starving the rendering/layout engine from computing the size (and more accurately figurnge out how few it actually should render.)
Before this change, with <FlatList maxToRenderPerBatch={5} data={objectOfLengthN} />, I essentially saw it doing:
```
{first: 0, last: 0}
{first: 0, last: 5}
{first: 0, last: 10}
....
{first: 0, last: N}
```
(no more hiPri renders since all elements have been rendered)
(actually renders and lays out all N objects, and computes their sizes)
(realizes that it doesn't need to show all N for my current screen size and row size)
```{first: 0, last: 55}```
After this change, that whole first part where it keeps incrementing `last` to try to "keep up with the scrolling" disappears.

Summary:
The React Native Remote Debugger page (`debugger.html`) contains an embedded silent sound file to maintain tab priority in Google Chrome.
This revision simply replaces the existing one with a better one that has the following characteristics:
- 1s Duration
- 10Hz Frequency
- -48dBFS Amplitude
- Fades in/out to reduce audible clicks on loop.
- 44.1kHz @ 16bit to maximimize compatibility.
- Smaller size.
Much thanks to Stephane Pigeon (http://stephanepigeon.com/) for designing the sound file specifically for this use case.

Summary:
The overflow: visible option does not work on Android. This just add a little note to the docs of that property to make that clear.
See #3198 and https://react-native.canny.io/feature-requests/p/add-overflow-support-to-android .
Make it clear that this property is unavailable on Android. We had to figure this out by trial and error when porting an existing codebase, a small note in the docs would be helpful!
I could not find how to build the website - I tried `cd website && npm install && node ./server/generate.js` but I'm getting an error (*JSDOC_ERROR: There are no input files to process.*). But it is such a small change I can't see how it would break the docs build!

Summary:
The only thing I found in the spec for this change is the following. Not exactly sure if this is the thing this PR is about:
> For each flex item, subtract its outer flex base size from its max-content contribution size. If that result is not zero, divide it by (if the result was positive) its **flex grow factor floored at 1** or (if the result was negative) by its scaled flex shrink factor, having **floored the flex shrink factor at 1**. This is the item’s max-content flex fraction.
But at least it seems a required change.

Summary:
C++ doesn't provide an implicit cast to an enum value from the enum's backing type. When a `.mm` file calls `RCT_ENUM_CONVERTER`, we end up with the following compiler error:
> Error: cannot initialize return object of type `<TypeName>` with an rvalue of type `NSInteger`
Since `RCT_ENUM_CONVERTER` is a macro, this error will appear whenever we try to expand the macro in a C++ context.
The project compiles and runs as expected when this additional cast is added 😃

Summary:
See https://github.com/facebook/react-native/issues/14326 for the bug
this fixes. This is a pretty ugly hack to work around what I think is
a CP bug. Since the C++ dependencies are only needed to build RN
itself, and not applications, don't the conflicting headers as source
files. Instead, use preserve_paths to get them unpacked into the
source tree under Pods/<Pod>, and arrange for them to get used with
HEADER_SEARCH_PATHS. This keeps them out of the project, so they
don't get included in the header map, and other (badly structured)
projects don't get confused.
