New architecture support #550

j-piasecki · 2022-08-04T15:03:26Z

Description

This PR adds Fabric integration to the FlashList. Here are some more important highlights:

Android:
- The events on Fabric need to be sent by the FabricUIManager so I made an Extension file for Fabric and for Paper (the correct one is added to the source set in build.gradle)
iOS:
- I've merged CellContainer with CellContainerComponentView as keeping a CellContainer in every CellContainerComponentView didn't look like a very good idea performance-wise
- In the case of AutoLayoutView, I stayed with wrapping it with the Fabric Component (AutoLayoutViewComponentView). I didn't want to accidentally break the functionality converting in to obj-c. It may be possible that they can be merged via inheritance but I'm not that knowledgeable in interop between swift and obj-c and couldn't get it to work
- Event dispatchers on Fabric are auto-generated so I added a field to AutoLayoutView containing a closure, which in turn is set by the AutoLayoutViewComponentView. This way the code in Swift has access to the generated obj-c++ method.
Fixture app
- I've added patches for safe-area-context and screens to make sure they work with RN 0.72 on the new architecture
- New architecture is now enabled by default in the app, which may not be desired. Let me know how you would like it handled.

So Fabric is actually making the performance worse? I was always hoping that Fabric is here to change that :D

Thanks @j-piasecki!

Do we have an idea why Fabric could be slower?

This line has a different syntax than this. Also, given React Native only supports 12.4 as of now, can't we just target 11.0 versions on both Paper and Fabric?

I updated it, so that it matches the main branch.

Is there a reason for having buck-related files and code inside the fixture app?

Not really, the fabricfixture was the result of react-native init. I found some problems with the app in the meantime so I set it up from scratch based on the fixture app.

Since we're creating a standalone app for the Fabric fixture – has the maintenance burden suffered on your side?

Have you considered looking at the react-native-test-app from Microsoft, which is now e.g. used in react-native-blur?

I haven't looked at react-native-test-app yet.

As for the standalone app for Fabric - I think it's currently the better approach. Most of the libraries don't support Fabric yet and having this layer of separation helps developing for both architectures. We also found that limiting the outside dependencies may be beneficial. As for now, every release of React Native (since 0.68) introduced some (at least for us) breaking changes - this caused problems when adapting our libraries to the newest versions, as we needed to fix problems in the app's dependencies first. Recently we've had that exact problem between Reanimated, Screens and Gesture Handler, because the example apps are dependant on our other libraries and we're considering simplifying them.

As for your question about the performance - at the moment the main suspect is the JS Fabric renderer as the performance improves significantly in release mode.

I have looked into it briefly, but I don't have anything concrete yet.

j-piasecki · 2022-09-21T12:36:46Z

I have an update - the terrible performance on Android in debug mode is related to Hermes. It seems that the Hermes gets built in debug mode which slows it down quite a bit. After replacing the libhermes.so inside the APK file with the one extracted from the app built in release mode (or from the debug build of an app in the old arch) the performance gets much better.

If I understand correctly, there is a plan to add support for Prefab to Hermes in React Native 0.71, which could mean that this particular problem will solve itself with the next React Native release.

cortinico · 2022-09-21T13:17:15Z

Sorry for jumping on this. I've been watching this as I have a side project app where I'm eager to try FlashList with Fabric.

Thanks for investigating this.

Technically you should not be blocked by 0.71.x in any form.
We're already shipping two .aar for Hermes, the hermes-engine-debug.aar and hermes-engine-release.aar. They contain libhermes.so files which are optimized for Debug/Release.

If I understand correctly, there is a plan to add support for Prefab to Hermes in React Native 0.71, which could mean that this particular problem will solve itself with the next React Native release.

Correct that we're actively looking into this. I'm wondering why this is affecting FlashList. Are you rebundling Hermes or doing anything related? If so, I'm curious to hear more as, in theory, libraries should behave transparently to the underlying JS engine.

j-piasecki · 2022-09-21T13:46:09Z

I may have misunderstood what using prefabs will mean. At the moment Hermes is being built from source, would that still be the case with prefabs?

I think that this could be a potential cause of performance problems. I've just improved the fps of the benchmark in debug mode (the same that the numbers in the PR description are from) by about 10 times by using ndk 21.4.7075529 (via Rosetta on M1 Pro) instead of ndk 24.0.8215888.

The way how hermes is built should be transparent to the end user and also to this library. The fact that we ship libhermes.so or you build it on your computer should make no difference.

You can still pick between Debug and Release when building your app, and Hermes will follow accordingly.

This is really odd and, unless NDK 24 changed the default compilation flags, should not happen.
As a rule of thumb I would suggest you run all of your benchmarks against the same NDK version/variant otherwise is really hard to track down potential regression and especially understand if they're related to Fabric or not.

tomekzaw · 2022-09-22T08:10:15Z

Hey @cortinico, sorry for jumping in here. Unfortunately, the issue with libhermes.so also affects not only performance but also the way how C++ exceptions are handled between shared library boundaries. This results in app crashes on Android when building with NDK 24.

Try creating a fresh RN 0.70 app, enable Fabric and add throw new Error('error'); somewhere in JS code, and build the app for Android. If you build the app on Intel-based Mac with NDK 21, the error appears in the red box as it should. However, if you build the app on M1-based Mac with NDK 24, the app crashes.

The last message in logcat is JSI rethrowing JS exception: [...]. It looks like libhermes.so throws a jsi::JSError
(https://github.com/facebook/hermes/blob/98670b0ed40b9edd5fd405dc5a28119ad0aff35f/API/hermes/hermes.cpp#L2278-L2280) but for some reason catch (jsi::JSError &e) (or even catch (...)) is not able to catch the exception and the app crashes. (On iOS the exception can be caught with catch (...) or catch (std::exception &e) but catch (jsi::JSError &e) doesn't work as probably due to duplicated symbols, but this sounds like a separate issue.)

We are highly affected by this bug in Reanimated (when worklet throws JS error the app crashes on Android with Fabric enabled if using NDK 24). The crash is gone when building with NDK 21 (or just replacing libhermes.so in app-debug.apk).

Thanks for flagging this @tomekzaw. The issue is quite concerning to me and I'd like to investigate further. Can you open an issue on Reanimated or on React Native and let's keep the convo there. I don't want to sidetrack this PR for FlashList 👍

j-piasecki · 2022-09-22T10:36:05Z

The way how hermes is built should be transparent to the end user and also to this library. The fact that we ship libhermes.so or you build it on your computer should make no difference.

I understand, and while it should make no difference, it seems like the tools used to build hermes may have a substantial effect on its performance. I feel like it's important to keep it in mind, especially now that hermes is built from source and we cannot guarantee the setup. It may lead to hard-to-explain performance problems, like the one I encountered with FlashList.

Also, it may be clear from your answer but I cannot infer whether the hermes will still be built locally in future 😅.

We're already shipping two .aar for Hermes, the hermes-engine-debug.aar and hermes-engine-release.aar. They contain libhermes.so files which are optimized for Debug/Release.

In that case, may I ask what's the reasoning for building it locally even though there is one already built available?

cortinico · 2022-09-22T10:53:29Z

Yes, we're looking into this at the moment. Most likely will land on the next major release of React Native

In that case, may I ask what's the reasoning for building it locally even though there is one already built available?

Sorry if I was unclear. What I meant that, regardless if you're building Hermes locally or getting a prebuilt, Hermes is 'variant aware'. So there is a hermes-engine-release.aar (either downloaded or prepared locally) which contains a version of Hermes optimized for Release.

To give you more context, the situation is a bit more complicate in terms of prebuilts as:

Users on Old Architecture don't need to compile any C++ code. Therefore they can use the prebuilt version of hermes-engine-release|debug.aar we ship for them (see bundled hermes docs here: https://reactnative.dev/architecture/bundled-hermes)
Users on New Architecture need to compile C++ code introduced by the new arch. Therefore they can't (yet) use the prebuilt version of hermes-engine-release|debug.aar as that's missing headers and other machinery to let it compile successfully.
- That's what we're looking into solving at the moment so every user, regardless of the arch, can use a prebuilt version of hermes on Android.

naqvitalha · 2022-09-23T04:09:35Z

@cortinico @j-piasecki My main worry with fabric right now is that we're not able to maintain 60fps on the UI thread. It seems like drops in JS thread directly impact UI thread in the new architecture.
Do we have any insights into it? It's incredibly difficult to maintain 60fps on the JS thread.
In the old arch few drops in JS thread did not make a difference while in the new arch these drops interrupt scroll. Even minor drops are noticeable.
I can look into this sometime in the future but I'd love to hear some ideas.

j-piasecki · 2022-09-23T12:02:49Z

I don't have any concrete ideas as to what may be the cause of it yet. What I can say is that after I overloaded the JS thread to the point where recycling the views in the list takes a few seconds, the scrolling itself remained smooth. Will investigate this more.

I think the stuttering may be caused by the text. Here's a part of a profiler session on Samsung Galaxy A53 (Release build):

And focused on one update command:

The duration of the FabricUIManager::mountViews call in the screenshot above is over 6ms, which is often enough to cause a visible frame drop.
You should be able to get the same results using Android profiler and recording a System Trace. Keep in mind that I added some more systrace sections in IntBufferBatchMountItem, SurfaceMountingManager and in relevant methods in ReactTextViewManager and TextLayoutManager.

Why do you need here both onBlankAreaEvent and topOnBlankAreaEvent?

To be honest, I don't remember 😅. It's been a while since I've written this, but it doesn't seem to be causing any issues when I removed topOnBlankAreaEvent.

Can you explain why do we need the extra view?

On the new architecture a lot of the code needed by views is implemented inside RCTViewComponentView which is written in ObjC++. Ideally to create a new view component on the new architecture, one would inherit after it but it has two problems:

it's not implemented on the old architecture, and would require some tricks to make it work

I don't think it's possible for a Swift class to inherit after ObjC++ class

Instead of that, it's possible to create a wrapper view that inherits after RCTViewComponentView (in this case AutoLayoutViewComponentView) that will handle props and events of the underlying view that's already been implemented.

Do we need these patches now? Can we just upgrade the dependencies?

They are necessary to address the breaking changes between different versions of React Native.

Can we just upgrade the dependencies?

In this case, it would need to be a downgrade since both screens and safe-area-context are on the newest versions, which are adapted for React Native 0.74.

Upgrading the version of RN used in the fixture app would also help (upgrading other dependencies like reanimated and gesture-handler would also be necessary) but I'm not sure whether that's desirable or even in scope of this PR.

@j-piasecki I'm gonna look into the e2e tests shortly.

LGTM, thanks a lot @j-piasecki for this PR!

@Hosam-hsm @jfalih

For tests follow steps

package.json: "@shopify/flash-list": "git+https://github.com/Shopify/flash-list.git"
Using: import FlashList from '@shopify/flash-list/src/FlashList';

@JJSLIoT it's released in v1.7.0

# Why The current docs has a grammar issue on the Flashlist section. When fixing the issue, I found out that Flashlist now does support the new architecture (see Shopify/flash-list#550 released in [v1.7.0](https://github.com/Shopify/flash-list/releases/tag/v1.7.0) on July 4th) and propose this line item be removed from the docs.  # How I removed the note about FlashList.  # Test Plan N/A  # Checklist  - [x] Documentation is up to date to reflect these changes (eg: https://docs.expo.dev and README.md). - [x] Conforms with the [Documentation Writing Style Guide](https://github.com/expo/expo/blob/main/guides/Expo%20Documentation%20Writing%20Style%20Guide.md) - [x] This diff will work correctly for `npx expo prebuild` & EAS Build (eg: updated a module plugin).
