As part of our goal to modernize and type our core components, we need to migrate off of createReactClass. This task is to track the work to remove createReactClass from our codebase.

We can only convert off of createReactClass if the components don't use any mixins. Step 1 and Step 2 were removing a few of the mixins. There are still a few mixins left and we will need to completely finish that before we can complete this issue.

However, we can at least get started by removing createReactClass from the components that currently don't use any mixins. The following is that list:

  • ReactAndroid/src/androidTest/js/ScrollViewTestModule.js
  • ReactAndroid/src/androidTest/js/UIManagerTestModule.js
  • RNTester/js/ListViewExample.js
  • RNTester/js/ImageExample.js
  • RNTester/js/TimerExample.js
  • RNTester/js/TextExample.ios.js
  • RNTester/js/ProgressBarAndroidExample.android.js
  • RNTester/js/PanResponderExample.js
  • RNTester/js/ListViewGridLayoutExample.js
  • RNTester/js/SwipeableFlatListExample.js
  • RNTester/js/ProgressViewIOSExample.js
  • RNTester/js/CameraRollView.js
  • IntegrationTests/LayoutEventsTest.js
  • IntegrationTests/ReactContentSizeUpdateTest.js
  • Libraries/Experimental/SwipeableRow/SwipeableRow.js

I got this list by running grep -L "mixins:" $(grep -l -r createReactClass .). None of these files seem to be convertible by the codemod provided by the react team.

I'm providing less instructions on this one because I think there are a lot of posts online about how to convert off of createReactClass.

@gengjiawen Facebook is still using requires and hasn't yet migrated to import/export. Some of the React Native optimizations like inline-requires are specifically for requires and the one for import isn't ready to go. We probably won't convert react-native's core to import/export until Facebook makes the switch over.

Thank you all for the work on this cleanup. This is amazing. This has all been building up to being able to improve our flow types for these components now that we aren't on prop-types. I created an issue with that work here: #22100.

Thanks again for everything you all have done so far!

* Improving Modal `visible` prop check to handle undefined and null (#22072)

Summary:
Changing the the this.props.visible if to be ` if (!!this.props.visible === false)` . So passing undefined, or other values wont set the modal to be visible. Granting that anything that is not true, will set the modal to null on the render.

I make this this PR, because on the company that im working, we used a lot of RN. At the moment, we arent using anything like flow or TS. But to grant that the modals will only show if they are set visible to true i have changed the if made.

* Performance improvement for loading cached images on iOS (#20356)

Summary:
This PR increases the speed at which cached images are loaded and displayed on the screen. Images are currently cached in memory using RCTImageCache, but each time they are loaded, a round trip through RCTNetworking happens before RCTImageCache is even checked. This is likely so that RCTNetworking can handle the caching behavior required by the HTTP headers. However, this means that at the very least, images are read from disk each time they're loaded.

This PR makes RCTImageLoader check RCTImageCache _before_ sending a request to RCTNetworking. RCTImageCache stores a bit of information about the response headers so that it can respect Cache-Control fields without needing a roundtrip through RCTNetworking.

Here are a couple of graphs showing improved loading times before this change (blue) and after (red) with SDWebImage (yellow) as a baseline comparison. The increase is most evident when loading especially large (hi-res photo size) images, or loading multiple images at a time.
https://imgur.com/a/cnL47Z0

More performance gains can potentially be had by increasing the size limit of RCTImageCache: https://github.com/facebook/react-native/blob/1a6666a116fd8b9e8637956de2b41a1c315dd470/Libraries/Image/RCTImageCache.m#L39 but this comes at the tradeoff of being more likely to run into OOM crashes.

* Update and expand bytecode spec

Summary:
* Adds parent tag as param for createNode in place of explicit appendChild commands.
* Adds version info to bytecode
* Adds native conditional support:

Conditionals are represented in product code with the new `NativeConditional` React
component. It takes params necessary to construct a native function call, and takes
a render prop as a child that passes the value of the native call as an arg. In
prod, the component would actually call the native module and render with that value,
but in jest we render for *both* true and false and set them as children
of a new jest-only primitive/host component which we special-case and generate a
special command with `OP_CODE.conditional`, generate the appropriate bytecode commands
for each branch, and embed them as args in the conditional OP_CODE command. When
evaluating the bytecode, only one set of commands is executed, based on the native
module value (which is evaluated with another new opcode which computes the value
and stuffs it in a "register").

Obviously generating this bytecode is kind of a cludge compared to prepack, but
when I asked @[501709947:Dominic] about it, he said they had no bytecode spec right
now, so I'm running ahead with this prototype. The main thing I'm focused on is
the C++/RN bytecode interpretter - this jest stuff is just a way to generate bytecode
for it to consume which could be replaced or augmented with many other approaches,
such as prepack, server rendering, etc.

Also piggybacked a bunch of other cleanup.

* mostly working on Android + OTA

Summary:
It works great on iOS, and mostly works on Android, and is now OTA'able as part of the screen config! Haven't done template view yet. One remaining issue:

Layout is borked on Android. I'm guessing the issue has to do with the timing of setting the constraints in `updateRootLayoutSpecs` and calling `mBinding.startSurface` which actually builds the shadow tree. If I try to call `updateRootLayoutSpecs` earlier, it just crashes immediately. Here's the layout it spits out, which clearly has -440 for the x of 420006, which is the RCTText component, causing it to get cut off on the left of the screen:
```
updateLayoutMountItem for reactTag: 420006 x: -440, y: -13, width: 931, height: 78
updateLayoutMountItem for reactTag: 420010 x: 26, y: 79, width: 0, height: 1651

* Fabric: Introducing UIManagerBinding, a replacement for JSIFabricUIManager

Summary:
This diff changes how we expose UIManager to JavaScript realm and control ownership of it. This change should improve reliability and a thread-safety.

UIManagerBinding is a HostObject which consolidate ownership of UIManager. Now JavaScript's GC controls its lifetime which eliminates the possibility of calling some JS facing methods of UIManager using a dangling pointer.
Besides that, all API now imply that if the caller has a reference to jsi::Runtime, it calls the method on the proper thread (it's an implication of RuntimeExecutor design).

* Give eagerly loaded modules precedent over lazily loaded one.

Summary: Before lazily-loading code existed, modules that were already loaded into memory took precedent over modules that were additionally registered. With lazily loading modules, instead of giving eagerly loaded modules precdence, it throws a redbox. This diff fixes that behavior.

* Stop mounting of Views when there is an exception in Native

Summary: This diff fixes exception handling for Mounting of views, as soon as there is an exception we stop the mounting of views because from that point the UI View tree is going to be inconsistent with the ReactShadow tree from C++. We also stop the mounting of views when the host is paused, this allows us to not keep mounting views

* Refactor 'induce' of events in Fabric Android

Summary:
This diff refactors the exeuction of 'AsyncEventBeat.induce()' as part of the delivery of events of Fabric Android implementation.
The first part of the refactor moves the exeuction of onBatchEventDispatched out of the synchronization block for mEventsToDispatchLock. This lock is accessed from the UI Thread and executing the induce inside this synchronization block will affect UI,
The second part of the refactor is to ensure that the exeuction of the C++ method AsyncEventBeat.induce() always happen in the JS Thread.

* Switch to synchronous strategy for unprotect

Summary:
Older versions of JSC (ios 11 and before) have a bug which I
believe the ProtectionQueue mechanism tickles:
https://bugs.webkit.org/show_bug.cgi?id=186827

This removes the ProtectionQueue and replaces it with an atomic flag
to avoid calling unprotect after VM shutdown.

This also fixes a race condition in shutdown.

* Back out TextInput es6 conversion

Summary:
This was failing due to issues with refs, which we were able to fix and then finally due to some jest tests that were failing due to things being null that shouldn't be which I couldn't easily figure out. Reverting the stack until we can actually solve it, hopefully with additional tests.

This was created by running:

* Adds support for `publicPath` to enable serving assets from different locations. (#299)

Summary:
<!-- Thanks for submitting a pull request! Please provide enough information so that others can review your pull request. The two fields below are mandatory. -->

**Summary**

<!-- Explain the **motivation** for making this change. What existing problem does the pull request solve? -->

This is an updated followup from https://github.com/facebook/metro/pull/280, which we would still need to address the following assumptions about `/assets/`:

https://github.com/facebook/metro/blob/e7deea19001d903a47868bb1fe6456bdc4b585e7/packages/metro/src/Server.js#L332

https://github.com/facebook/metro/blob/e7deea19001d903a47868bb1fe6456bdc4b585e7/packages/metro/src/Server.js#L385

As pointed out by gdborton, there isn't currently a way to make this a configurable option. I am not certain how to find a proper workaround for `processRequest`.

We found a temporary solution to have our express app pick up serving the assets from a publicPath as a middleware. But the change in this PR is still necessary to get it working fully.

**Test plan**

<!-- Demonstrate the code is solid. Example: The exact commands you ran and their output, screenshots / videos if the pull request changes UI. -->

- Will add tests once we figure out a comprehensive solution

* Fix ReactInstanceManager deadlock

Summary:
D12829677 introduced a deadlock where onHostResume holds the lock on `moveToResumedLifecycleState()` then waits for the `mReactContext` lock, but at the same time setupReactContext holds the `mReactContext` lock and waits for `moveToResumedLifecycleState()` https://our.intern.facebook.com/intern/everpaste/?handle=GAgXFgLQH1ZlQikBAMQzo2LZ6h9TbiAxAAAz. The purpose of the previous diff was to make sure that detachRootoView and
setupReactContext did not interfere with each other, and implemented that by blocking on mReactContext. Since this overloads the usage of mReactContext, let's use a different lock `mAttachedRootViews` to implement this behavior instead
