Remove "es6-symbol" package from DevTools #18397

bvaughn · 2020-03-26T16:19:28Z

This polyfill was copied over from DevTools v3 but given the current browser compatibility for Symbol, I think it's safe to remove.

This will also reduce the size on disk for react-devtools-inline- since es6-symbol depends on es5-ext which is kind of large. (react-devtools-extensions still depends on es6-symbol indirectly, because of web-ext, but this at least react-devtools-inline doens't.)

Thanks so much for cleaning this up! Do you mind deploying a new version of the devtools into xplat/js after merging this?

Thanks so much for cleaning this up! Do you mind deploying a new version of the devtools into xplat/js after merging this?

Landing things in xplat can be a hassle, and this isn't top priority for me at the moment. I'll take a shot at it, assuming it doesn't take too long. :)

The CLI had to be explicitly started from the project root, otherwise Metro didn't work right. In order to resolve the project root in the most accurate way, React Native assumed that project root is always `../../` from its location in `node_modules` - this is not true when the installation gets hoisted (e.g. in a monorepo). To address that, janicduplessis brought support for custom [`PROJECT_ROOT`](https://github.com/facebook/react-native/commit/9ccde378b6e6379df61f9d968be6346ca6be7ead) that allowed overriding the `../../` in case it wasn't true. Today, CLI is able to automatically resolve the project root, no matter where it's started. It will traverse the tree of the directories upwards and stop as soon as it meets `package.json`. As a result, it doesn't really matter from where we start the CLI anymore as a part of `react-native-xcode.sh`. By replacing the default value of `$REACT_NATIVE_DIR/../../` with `$PWD, that is default for all Xcode scripts, we can make the setup for monorepo easier - nobody will need to set `$PROJECT_ROOT` in order to override the incorrect defaults. By default, all scripts defined in Xcode run from `$PWD` directory, which is the location of the iOS project. In the future, we will be able to remove `cd` entirely. To better understand this PR, let's look a few hypothetical structures as an example: #### Monorepo: > tl;dr works out of the box, no need to mess around with paths ``` - package.json - packages/ - my-app/ - index.js - package.json - ios/ - MyApp.xcodeproj ``` **Before this PR**, the `react-native-xcode.sh` will start the CLI like this: ```bash cd $REACT_NATIVE_DIR/../../ node <absolute_path_to_cli.js> bundle --entry-point index.js ``` - Because we change the directory to the root of monorepo, CLI throws an error. All in all, there's no `react-native` dependency at the workspace root. - Some users turn `no hoist` in an act of troubleshooting the errors, which resolves the problem - `react-native` is moved under `my-app/node_modules` which makes this mechanism resolve properly. - Some users find out about `PROJECT_ROOT` and set it to overwrite the default value. For example, setting `export PROJECT_ROOT = "$PWD/../` will set the directory to `my-app`, which has a dependency on `react-native` in a `package.json` and makes the CLI happy. **After this PR**, the `react-native-xcode.sh` will start the CLI like this: ```bash cd $PWD node <absolute_path_to_cli.js> bundle --entry-point index.js ``` - The `$PWD` is `packages/my-app/ios/` because that's where the Xcode project is located. CLI will automatically set the root to `../` because that's where it finds `package.json` with `react-native` dependency. It will pass that root to Metro, unless users have set a different one themselves. Thanks to that, all paths to JavaScript files remain working and unaffected. - No need to set `PROJECT_ROOT` anymore. - We don't rely on the location of `node_modules`, which is cleaner and future proof. #### Standard: > tl;dr no changes ``` - ios/ - MyApp.xcodeproj - index.js - package.json ``` **Before this PR**, the `react-native-xcode.sh` will start the CLI like this: ```bash cd $REACT_NATIVE_DIR/../../ node <absolute_path_to_cli.js> bundle --entry-point index.js ``` - Everything works fine. Path from `react-native` inside `node_modules` is correct - the project root is set right to `/` **After this PR**, the `react-native-xcode.sh` will start the CLI like this: ```bash cd $PWD node <absolute_path_to_cli.js> bundle --entry-point index.js ``` - The root will be set to where Xcode project is located, which is `/ios`. This is the PWD for all Xcode scripts. CLI will look for the `package.json` going upwards from `ios` folder. Will stop at `/`, find out it has `react-native` dependency, load it and its commands and proceed further. ## Changelog [iOS] [Feature] - Better monorepo support when building release apk Pull Request resolved: https://github.com/facebook/react-native/pull/28354 Test Plan: - All projects (standard/monorepo) run without issues. - PROJECT_ROOT is not needed.

Previously this was ok because the change was only coming from native, any changes from JS were ignored. Imagine following scenario: 1. User taps key. 2. Update state is called on component initiated by native. 3. New state is created with incremented revision by one. 4. `_stateRevision` gets set to new state's revision + 1. 5. Now JS wants to change something because it just learnt that user tapped the key. 6. New state is created again with incremented revision by one. 7. Update state is called on the component, but the change isn't applied to the text view because `_state->getRevision()` will equal `_stateRevision`. By having a BOOL instead of number, we very explicitly mark the region in which we don't want state changes to be applied to text view. ## Calling [_backedTextInputView setAttributedText] move cursor to the end of text input This is prevented by storing what the current selection is and applying it after `[_backedTextInputView setAttributedText]` is called. This was previously invisible because JS wasn't changing contents of `_backedTextInputView`. ## Storing of previously applied JS attributed string in state This is the mechanism used to detect when value of text input changes come from JavaScript. JavaScript sends text input value changes through props and as children of TextInput. We compare what previously was set from JavaScript to what is currently being send from JavaScript and if they differ, this change is communicated to the component. Previously only first attributed string send from JavaScript was send to the component. # Problem If children are used to set text input's value, then there is a case in which we can't tell what source of truth should be. Let's take following example We have a text field that allows only 4 characters, again this is only a problem if those 4 characters come as children, not as value. This is a controller text input. 1. User types 1234. 2. User types 5th character. 3. JavaScript updates TextInput, saying that the content should stay 1234. 4. In `TextInputShadowNode` `hasJSUpdatedAttributedString` will be set to false, because previous JS value is the same as current JS value.

Disable Fabric (because CMD + R doesn't work with Fabric right now). 2. Open up Marketplace and hit `CMD + OPT + R` 3. **Observe:** The progress bar doesn't show up right away. It also doesn't actually show progress. https://pxl.cl/140g1 RN Support post: https://fb.workplace.com/groups/rn.support/permalink/3437652016283389/ ## Fixes The first problem is that progress bar doesn't actually show progress. **Fix:** Bundle load progress is updated in `RCTCxxBridge`, where we first require `RCTDevLoadingView`, and then call its `updateProgress` method. Previously, we wouldn't lazily load `RCTDevLoadingView`, it already didn't exist. Lazily loading `RCTDevLoadingView` causes the progress view to show up. Here: https://pxl.cl/140gt If you look at the above video, you'll notice there are two stages to the progress bar: stage 1 displays the actual progress. Stage 2 prompts that we're downloading the JS bundle. As you can see, stage 1 and stage 2 have different background colors, even though both of them are green. **Fix:** I adjusted the JS to match the Native color. Here: https://pxl.cl/140gT We're almost there, but the progress bar is dismissed twice? **Fix:** I dug into the code, and the reason why was because when we hit `CMD + R`, we invalidate the bridge, and immediately re-initialize it. This means that we asynchronously invalidate the old TurboModuleManager, and immediately create a brand new one. Therefore, two `RCTDevLoadingView` modules can (and do) exist at once. So, I moved `RCTDevLoadingView` to be an instance member of `FBReactModule`, to ensure that it doesn't get cleaned up and re-created when TurboModuleManager is deleted and re-created.

The previous attempt was in D19249490. I don't know why we don't see production crashes (stalls) but it happened to me (and not to me) in the debugger. The previous attempt didn't work because we still could have a deadlock because we tried to acquired shared mutex already owned exclusively by the `suspend` method. Here is another approach: Instead of using one shared mutex, now we use two. One is similar to what we had and another that protects `suspend` and `resume`. Besides that, now we pass a Scheduler to functions that use that explicitly. This way we can be more explicit about acquiring mutexes and the overall flow of execution. The idea is: Now an arbitrary code that can be reentrant does not cover with mutexes, so the deadlock is not possible. Changelog: [Internal] Fabric-specific internal change.

Instead, you can use `<ScrollView ref={myRef} />` and directly call all methods of ScrollView and host components on `myRef`. Previous usage: ``` const myRef = React.createRef<React.ElementRef<typeof ScrollView>>(); <ScrollView ref={myRef} /> const innerViewRef = myRef.current.getNativeScrollRef(); innerViewRef.measure(); ``` New usage: ``` const myRef = React.createRef<React.ElementRef<typeof View>>(); <ScrollView ref={myRef} /> // now, myRef.current can be used directly as the ref myRef.current.measure(); myRef.current.measureLayout(); // Additionally, myRef still has access to ScrollView methods myRef.current.scrollTo(...); ``` Changes: * Added deprecation warnings to ScrollView methods `getNativeScrollRef`, `getScrollableNode`, and `getScrollResponder` * Added the forwardRef call to create `ForwardedScrollView` - this takes in `ref` and passes it into the class ScrollView as `scrollViewRef`. * Forwarded the ref to the native scroll view using `setAndForwardRef`. * Added statics onto `ForwardedScrollView` so that `ScrollView.Context` can still be accessed. * Added type `ScrollViewImperativeMethods`, which lists the public methods of ScrollView. * Converted all public methods of ScrollView to arrow functions. This is because they need to be bound to the forwarded ref. * Bound all public methods of ScrollView to the forwarded ref in the `setAndForwardRef` call. * Flow typed the final output (ForwardedScrollView) as an abstract component that takes in the props of the `ScrollView` class, and has all methods of both the inner host component (`measure`, `measureLayout`, etc) and the public methods (`scrollTo`, etc).

There are three optimized paths before the slow path. The first optimized path tries to pair identical nodes from old/new tree, and generate Update mutations, until we hit nodes that are different (indicating either a remove or an insert). This already existed. The next two optimizations, introduced by Tim in his JS pseudocode, were inspired by ReactJS's diffing algorithm. They work in cases where the rest of the nodes are (1) all removals/deletes or (2) all creates+inserts. Finally, if those final two optimized paths can't run, it's because there is a mix of delete+remove, create+insert, and "move" operations, mixed at the beginning, middle, and/or end of the list. This has slightly better average/best-case complexity as the previous implementation. In particularly pathological cases where all nodes are arbitrarily reordered, or reversed, for instance (ABCDE->EDCBA) the algorithm has the same complexity as the previous algorithm (quadratic).

The primary method for an app to specify such colors is via the `PlatformColor()` method that takes string arguments. The `PlatformColor` method returns an opaque Flow type enforcing that apps use the PlatformColor method instead of creating Objects from scratch -- doing so would make it harder to write static analysis tools around Color values in the future. But in addition to `PlatformColor()`, iOS has a `DynamicColorIOS()` method that takes an Object. The Flow type for this Object cannot be opaque, but we still want to enforce that app code doesn't pass variables instead of Object literals or that values in the Objects are variables. To ensure `DynamicColorIOS()` can be statically analyzed this change adds an ESLint rule to enforce that `DynamicColorIOS()` takes an Object literal of a specific shape. A `ColorAndroid()` was also introduced not for practical use but just to test having platform specific methods for more than one platform in the same app. A second ESLint rule is created for `ColorAndroid` as well. ## Changelog [General] [Changed] - Add ES Lint rules for `DynamicColorIOS()`and `ColorAndroid()` Pull Request resolved: https://github.com/facebook/react-native/pull/28398 Test Plan: `yarn lint` passes.

The config was changed sometime in November 2019 (as part of https://github.com/facebook/react-native/issues/26940, commit https://github.com/facebook/react-native/commit/a3b08048674e324dbe1f0ca816f35607e9e06a2f) to be very opinionated when it comes to the use of `npx` which Gradle itself cannot find anyway (I have `npx` installed globally and it didn't pick it up). Another issue that the use of `npx` creates is that Gradle should only ever use the currently installed react-native cli rather than a (possibly) higher version which may not always have backward compatibility. The proposed change simply throws a more descriptive error rather than defaulting to a tool which may or may not exist on the machine, be it CI or a development environment. I've also modified the RNTester app to reflect the correct config implementation relative to the RNTester app itself. In real projects, the config inside `android/app/build.gradle` should look similar to the following snippet: ``` project.ext.react = [ cliPath: "$rootDir/../node_modules/react-native/cli.js", entryFile: "index.js" ]; ``` ## Changelog [Android] [Fixed] - Gradle release config Pull Request resolved: https://github.com/facebook/react-native/pull/28415 Test Plan: - [x] Successfully bundled an Android release build with correct config - [x] Works with RNTester app Reviewed By: mdvacca Differential Revision: D20714372 Pulled By: hramos fbshipit-source-id: 4d66139249c6f840582a71a48c64e6a6595f7af0 * Reimplement D19965405: Small improvements in Differentiator/TinyMap Summary: Two things: 1) I reimplement Valentin's idea in D19965405, so that TinyMaps can be iterated over, with a couple of bugfixes (calling front() or back() on an empty vector will crash). 2) I now use TinyMap instead of better::map in the "optimized" diffing algorithm. 3) `erase` now actually removes elements from the vector, but only when more than half of elements have been erased. 4) If you repeatedly erase elements at the beginning of the vector, they will no longer be iterated over. This is a specific optimization for our heaviest TinyMap use-cases. These amount to some small but hopefully somewhat meaningful perf improvements.

I looked at all call sites, and they are either always both set to true or both set to false. # 2nd The way we include scroll view content offset, is through transformation, so setting `includeTransform` to true and `includeScrollViewContentOffset` to false will include content offset anyway. In order to make both flags work, we would need to introduce further changes to `getRelativeLayoutMetrics`. But since the flag isn't used anyway, I think it is better to get rid of it for now. If we need it in the future, we could re-introduce it.

This applies if view's parent has transformation as well, because transformation is applied to all subviews of the view as well.

We then implement that same function for Fabric in order to support the inspector in that renderer. Requires https://github.com/facebook/react/pull/18388 ## Motivation Reason one for this refactor is that, previously, the inspector held all of the logic to look up view data for a given x,y touch coordinate. To do this, it would take the React tag and coordinates, look up the native view tag, measure it, and then ask React internals for the Fiber information of that tag. All of this is deeply coupled to React internals, yet the logic is outside of React core in the Inspector. Reason two is that, for Fabric, the logic for getting the view data is different than Paper. In Fabric, we pass the x,y coordinates to native directly, which returns an instance handle. That handle can be used to measure the ShadowNode, or retrieve the Fiber information. By moving the logic into the renderer in React core, we decouple the implementation details of looking up view data for a tapped point and allow ourselves the ability to add and change renderer-specific code for the actual lookup without impacting outsiders like the Inspector.

After digging into React Profiler code, I found out that it's using `performance.now()` to accumulate execution times of individual units of work. Since this method does not exist in React Native, it falls back to Javascript `Date`, leading to imprecise results. This PR introduces `global.nativePerformanceNow` function which returns precise native time, and a very basic `performance` polyfill with `now` function. This will greatly improve React Profiler API results, which is essential for profiling and benchmark tools.

From Tzvetan's internal post on the subject: > [Today] the interpreter IP is just a local variable in the interpreter function, so there is no way to get to its value from outside the function. It lives in a register and we don't want to make it a Runtime field since the overhead [of accessing it via memory in the interpeter loop] would kill us. > However, if you really think about it, it only lives in a register while the interpreter function is running. For the rest of the time, it is spilled by the C++ compiler onto the stack. So, precisely when we need it, it is actually stored in memory. The only problem is, we don't know where! Admittedly, that is an annoying problem, but it feels like it should be solvable. > What if, instead of relying on the compiler to spill the IP register, we manually spill it ourselves, to a known location? It works. Example: https://godbolt.org/z/ftSDnp This diff implements this approach across the whole interpreter loop: whenever we call out of the loop we capture/publish the IP and restore it again immediately after the external call returns. This means we can now see the IP outside the interpret loop and even change it. This is effectively "for free" as the compiler now skips spilling/restoring the IP behind the scenes. The immediate benefit of this is knowing the current IP allows us to have more accurate stack-traces during execution. In future this may enabled tricks like changing the IP before returning to th…

(In the web page with React DOM or shipped on the device with the React Native runtime.) This release updates the [**protocol** that DevTools uses](https://github.com/facebook/react/blob/main/packages/react-devtools/OVERVIEW.md#serializing-the-tree) to communicate between the "frontend" and "backend" components. Because React Native embeds a copy of the React DevTools "backend" ([`react-devtools-core/backend`](https://www.npmjs.com/package/react-devtools-core)), the "frontend" (UI) needs to match. This means you may be prompted to upgrade (or downgrade) your React DevTools based on which version of React Native your app uses. #### Features * Support multiple DevTools instances per page ([@bvaughn](https://github.com/bvaughn) in [facebook#22949](facebook#22949)) * Advocate for StrictMode usage within Components tree ([@bvaughn](https://github.com/bvaughn) in [facebook#22886](facebook#22886)) * StyleX plug-in for resolving atomic styles to values for props.xstyle ([@bvaughn](https://github.com/bvaughn) in [facebook#22808](facebook#22808)) * Timeline search ([@bvaughn](https://github.com/bvaughn) in [facebook#22799](facebook#22799)) * Timeline: Improved snapshot view ([@bvaughn](https://github.com/bvaughn) in [facebook#22706](facebook#22706)) * Display root type for root updates in "what caused this update?"

React’s previous Profiler primarily reports how fast (or slow) components are when rendering. It didn’t provide an overview of *what React is doing* (the actual cooperative scheduling bits). The new profiler does. It shows when components schedule state updates and when React works on them. It also shows how React categorizes and prioritizing what it works on. Here’s a profile for a simple app that uses only the legacy (synchronous) `ReactDOM.render` API. The profiler shows that all of the work scheduled and rendered by this app is done at *synchronous* priority: https://user-images.githubusercontent.com/29597/129042321-56985f5a-264e-4f3a-a8b7-9371d75c690f.mp4 Here’s a more interesting profile for an app that’s rendered at _default_ priority using the new [`createRoot` API](reactwg/react-18#5), then updates _synchronously_ in response to an “input” event to manage a ["controlled component"](https://reactjs.org/docs/forms.html#controlled-components): https://user-images.githubusercontent.com/29597/129074959-50912a63-0215-4be5-b51b-1e0004fcd2a1.mp4 Here’s part of a profile showing an idle app (no JavaScript running). In this case, React does some pre-rendering work for components that are “offscreen” (not currently displayed). https://user-images.githubusercontent.com/29597/128971757-612f232f-c64f-4447-a766-66a0516e8f49.mp4 Note that “offscreen” refers to a new API and set of features that we haven’t talked about much yet except for [some passing references](reactwg/react-18#18 (reply in thread)). We’ll talk more about it in future posts. ###### What are “transitions” and how do they work? We recently shared an update about the new [`startTransition` API](reactwg/react-18#41). This API helps apps feel responsive even when there are large updates by splitting the work into (1) a quick update to show that the app has received some input and (2) a slower update (the “transition”) that actually does any heavy lifting needed as a result of the input. Here is an example profile that uses the transition API. First React renders a small update that shows the user some visual feedback (like updating a controlled component or showing an inline loading indicator). Then it renders a larger update that, in this case, computes some expensive value. https://user-images.githubusercontent.com/29597/129079176-0995c8c0-e95a-4f44-8d55-891a7efa35c0.mp4 ###### How does Suspense impact rendering performance? You may have heard mention of “suspense” in past talks or seen it referenced [in our docs](https://reactjs.org/docs/react-api.html#suspense). Although full support for data fetching via Suspense is [expected to be released sometime after React 18.0](reactwg/react-18#47 (comment)), you can use Suspense today for things like lazy-loading React components. The new profiler shows when components suspend during render and how that impacts overall rendering performance. Here’s an example profile that suspends during the initial render to lazy-load a component using [`React.lazy`](https://reactjs.org/docs/code-splitting.html#reactlazy). While this component is loading, React shows a “fallback“ (placeholder UI). Once the component finishes loading, React retries the render and commits the final UI. https://user-images.githubusercontent.com/29597/129054366-2700e7e8-0172-4f61-9453-475acd740456.mp4 We plan to expand support for Suspense in the coming weeks to more explicitly show when suspense fallbacks are rendered and which subsequent renders are related to an initial update that suspended. ###### What else might cause a render to get delayed? Suspense can cause a render to get delayed as React waits for data to load, but React can also get stuck waiting on a lot of JavaScript to run. React profiling tools have previously focused on only reporting what React (or React components) are doing, but any JavaScript the browser runs affects performance. The new profiler shows non-React JavaScript as well, making it easy to see when it delays React from rendering. https://user-images.githubusercontent.com/29597/128971952-7c4e7e11-f4fb-497e-b643-4d9b3994b590.mp4 ###### What can you do to improve performance? Until now, DevTools (and the Profiler) has provided information without commentary. The new profiler takes a more active approach– highlighting where we think performance can be improved and providing suggestions. For example, suspending during an update is generally a bad user experience because it causes previously shown components to be unmounted (hidden) so the fallback can be shown while data loads. This can be avoided using the new [Transition API](reactwg/react-18#41). If you forget to add a transition to an update that suspends, the new profiler will warn you about this: https://user-images.githubusercontent.com/29597/128972228-3b23f01a-8017-43ad-b371-975ffed26c06.mp4 The new profiler also warns about scheduling a long, synchronous React update inside of event handler. https://user-images.githubusercontent.com/29597/128972000-d7477ba3-b779-46f2-b141-aaa712e9d6d2.mp4 Another thing the new profiler will warn about is long-running renders scheduled from layout effects (`useLayoutEffect` or `componentDidMount`/`componentDidUpdate`). These updates (called “nested updates”) are sometimes necessary to adjust layout before the browser paints, but they should be *fast*. Slow nested updates make the browser feel unresponsive. https://user-images.githubusercontent.com/29597/128972017-3ed0e682-751c-46fb-a6c5-271f255c8087.mp4 --- ### 4.14.0 July 17, 2021 #### Features *

That overhead has been effectively eliminated in version 4. [Learn more](https://github.com/facebook/react/blob/main/packages/react-devtools/OVERVIEW.md) about the performance optimizations that made this possible. #### Component stacks React component authors have often requested a way to log warnings that include the React ["component stack"](https://reactjs.org/docs/error-boundaries.html#component-stack-traces). DevTools now provides an option to automatically append this information to warnings (`console.warn`) and errors (`console.error`). ![Example console warning with component stack added](https://user-images.githubusercontent.com/29597/62228120-eec3da80-b371-11e9-81bb-018c1e577389.png) It can be disabled in the general settings panel: ![Settings panel showing "component stacks" option](https://user-images.githubusercontent.com/29597/62227882-8f65ca80-b371-11e9-8a4e-5d27011ad1aa.png) --- ### Components tree changes #### Component filters Large component trees can sometimes be hard to navigate. DevTools now provides a way to filter components so that you can hide ones you're not interested in seeing. ![Component filter demo video](https://user-images.githubusercontent.com/29597/62229209-0bf9a880-b374-11e9-8f84-cebd6c1a016b.gif) Host nodes (e.g. HTML `<div>`, React Native `View`) are now hidden by default, but you can see them by disabling that filter. Filter preferences are remembered between sessions. #### No more inline props Components in the tree no longer show inline props. This was done to [make DevTools faster](https://github.com/facebook/react/blob/main/packages/react-devtools/OVERVIEW.md) and to make it easier to browse larger component trees. You can view a component's props, state, and hooks by selecting it: ![Inspecting props](https://user-images.githubusercontent.c…
