…to frontend (#30610) Stacked on #30597 and whats under it. See [this commit](59b4efa). With this change, the initial values for console patching settings are propagated from hook (which is the source of truth now, because of #30596) to the UI. Instead of reading from `localStorage` the frontend is now requesting it from the hook. This happens when settings modal is rendered, and wrapped in a transition. Also, this is happening even if settings modal is not opened yet, so we have enough time to fetch this data without displaying loader or similar UI.
…s across sessions (#30636) Stacked on #30610 and whats under it. See [last commit](248ddba). Now, we are using [`chrome.storage`](https://developer.chrome.com/docs/extensions/reference/api/storage) to persist settings for the browser extension across different sessions. Once settings are updated from the UI, the `Store` will emit `settingsUpdated` event, and we are going to persist them via `chrome.storage.local.set` in `main/index.js`. When hook is being injected, we are going to pass a `Promise`, which is going to be resolved after the settings are read from the storage via `chrome.storage.local.get` in `hookSettingsInjector.js`.
Rewrite `containerInfo?.ownerDocument?.defaultView ?? window` to instead use a ternary. This changes the compilation output (see [bundle changes from #30951](d65fb06)). ```js // compilation of containerInfo?.ownerDocument?.defaultView ?? window var $jscomp$optchain$tmpm1756096108$1, $jscomp$nullish$tmp0; containerInfo = null != ($jscomp$nullish$tmp0 = null == containerInfo ? void 0 : null == ($jscomp$optchain$tmpm1756096108$1 = containerInfo.ownerDocument) ? void 0 : $jscomp$optchain$tmpm1756096108$1.defaultView) ? $jscomp$nullish$tmp0 : window; // compilation of ternary expression containerInfo = null != containerInfo && null != containerInfo.ownerDocument && null != containerInfo.ownerDocument.defaultView ? containerInfo.ownerDocument.defaultView : window; ``` This also reduces the number of no-op bundle syncs for Meta. Note that Closure compiler's `jscomp$optchain$tmp<HASH>` identifiers change when we rebuild (likely due to version number changes). See [workflow](https://github.com/facebook/react/actions/runs/10891164281/job/30221518374) for a PR that was synced despite making no changes to the runtime.
## Summary Builds `react-dom` for React Native so that it also populates the `builds/facebook-fbsource` branch. **NOTE:** For Meta employees, D61354219 is the internal integration. ## How did you test this change? ``` $ yarn build … $ ls build/facebook-react-native/react-dom/cjs ReactDOM-dev.js ReactDOM-prod.js ReactDOM-profiling.js ```
…ore/backend (#30987) Stacked on #30986. Previously, we would call `installHook` at a top level of the JavaScript module. Because of this, having `require` statement for `react-devtools-core` package was enough to initialize the React DevTools global hook on the `window`. Now, the Hook can actually receive an argument - initial user settings for console patching. We expose this as a function `initialize`, which can be used by third parties (including React Native) to provide the persisted settings. The README was also updated to reflect the changes.
…0995) If JSX receives a props spread without additional attributes (besides `ref` and `key`), we can pass the spread object as a property directly to avoid the extra object copy. ``` <Test {...propsToSpread} /> // {props: propsToSpread} <Test {...propsToSpread} a="z" /> // {props: {...propsToSpread, a: "z"}} ```
…sx (#30996) Based on #30995 ([rendered diff](https://github.com/jackpope/react/compare/inline-jsx-2...jackpope:react:inline-jsx-3?expand=1)) ____ Some apps still use `react.element` symbols. Not only do we want to test there but we also want to be able to upgrade those sites to `react.transitional.element` without blocking on the compiler (we can change the symbol feature flag and compiler config at the same time). The compiler runtime uses `react.transitional.element`, so the snap fixture will fail if we change the default here. However I confirmed that commenting out the fixture entrypoint and running snap with `react.element` will update the fixture symbols as expected.
In #30596 we've moved console patching to the global hook. Generally speaking, the patching happens even before React is loaded on the page. If browser DevTools were opened after when `console.error` or `console.warn` were called, the source script will be `hook.js`, because of the patching.  This is because ignore listing is not applied retroactively by Chrome DevTools. If you had it open before console calls, Hook script would be correctly filtered out from the stack:  I had hopes that the fix for https://issues.chromium.org/issues/345248263 will also apply ignore listing retroactively, but looks like we need to open a separate feature request for the Chrome DevTools team. With these changes, if user attempts to open `hook.js` script, they are going to see this message: 
## Overview Adds a lint rule to prevent optional chaining to catch issues like #30982 until we support optional chaining without a bundle impact.

When aborting we currently don't produce a componentStack when aborting the shell. This is likely just an oversight and this change updates this behavior to be consistent with what we do when there is a boundary
) This tracks the current window.event.timeStamp the first time we setState or call startTransition. For either the blocking track or transition track. We can use this to show how long we were blocked by other events or overhead from when the user interacted until we got called into React. Then we track the time we start awaiting a Promise returned from startTransition. We can use this track how long we waited on an Action to complete before setState was called. Then finally we track when setState was called so we can track how long we were blocked by other word before we could actually start rendering. For a Transition this might be blocked by Blocking React render work. We only log these once a subsequent render actually happened. If no render was actually scheduled, then we don't log these. E.g. if an isomorphic Action doesn't call startTransition there's no render so we don't log it. We only log the first event/update/transition even if multiple are batched into it later. If multiple Actions are entangled they're all treated as one until an update happens. If no update happens and all entangled actions finish, we clear the transition so that the next time a new sequence starts we can log it. We also clamp these (start the track later) if they were scheduled within a render/commit. Since we share a single track we don't want to create overlapping tracks. The purpose of this is not to show every event/action that happens but to show a prelude to how long we were blocked before a render started. So you can follow the first event to commit. <img width="674" alt="Screenshot 2024-09-20 at 1 59 58 AM" src="https://github.com/user-attachments/assets/151ba9e8-6b3c-4fa1-9f8d-e3602745eeb7"> I still need to add the rendering/suspended phases to the timeline which why this screenshot has a gap. <img width="993" alt="Screenshot 2024-09-20 at 12 50 27 AM" src="https://github.com/user-attachments/assets/155b6675-b78a-4a22-a32b-212c15051074"> In this case it's a Form Action which started a render into the form which then suspended on the action. The action then caused a refresh, which interrupts with its own update that's blocked before rendering. Suspended roots like this is interesting because we could in theory start working on a different root in the meantime which makes this timeline less linear.

A slight behavior change here too is that I now mark the start of the commit phase before the BeforeMutationEffect phase. This affects `<Profiler>` too. The named sequences are as follows: Render -> Suspended or Throttled -> Commit -> Waiting for Paint -> Remaining Effects The Suspended phase is only logged if we delay the Commit due to CSS / images. The Throttled phase is only logged if we delay the commit due to the Suspense throttling timer. <img width="1246" alt="Screenshot 2024-09-20 at 9 14 23 PM" src="https://github.com/user-attachments/assets/8d01f444-bb85-472b-9b42-6157d92c81b4"> I don't yet log render phases that don't complete. I think I also need to special case renders that or don't commit after being suspended.
The trailing / was being omitted, so instead of moving the cjs directory itself, it would move only its contents instead. This broke some internal path assumptions. Additionally, updates the step to create the react-dom directory prior to moving. ghstack-source-id: b6eedb0c88cd3aa3a786a3d3d280ede5ee81a063 Pull Request resolved: #31026

This is a follow-up from #30528 to not only handle props (the critical change), but also the owner ~and stack~ of a referenced element. ~Handling stacks here is rather academic because the Flight Server currently does not deduplicate owner stacks. And if they are really identical, we should probably just dedupe the whole element.~ EDIT: Removed from the PR. Handling owner objects on the other hand is an actual requirement as reported in vercel/next.js#69545. This problem only affects the stable release channel, as the absence of owner stacks allows for the specific kind of shared owner deduping as demonstrated in the unit test.
…ng raw fiber instance (#31009) Related - #30899. Looks like this was missed. We actually do this when we record errors and warnings before sending them via Bridge: https://github.com/facebook/react/blob/e4953922a99b5477c3bcf98cdaa2b13ac0a81f0d/packages/react-devtools-shared/src/backend/fiber/renderer.js#L2169-L2173 So, what is happening in the end, errors or warnings are displayed in the Tree, but when user clicks on the component, nothing is shown, because `fiberToComponentLogsMap` has only `alternate` as a key.
#31010) Stacked on #31009. 1. Instead of keeping `showInlineWarningsAndErrors` in `Settings` context (which was removed in #30610), `Store` will now have a boolean flag, which controls if the UI should be displaying information about errors and warnings. 2. The errors and warnings counters in the Tree view are now counting only unique errors. This makes more sense, because it is part of the Elements Tree view, so ideally it should be showing number of components with errors and number of components of warnings. Consider this example: 2.1. Warning for element `A` was emitted once and warning for element `B` was emitted twice. 2.2. With previous implementation, we would show `3⚠️ `, because in total there were 3 warnings in total. If user tries to iterate through these, it will only take 2 steps to do the full cycle, because there are only 2 elements with warnings (with one having same warning, which was emitted twice). 2.3 With current implementation, we would show `2⚠️ `. Inspecting the element with doubled warning will still show the warning counter (2) before the warning message. With these changes, the feature correctly works. https://fburl.com/a7fw92m4

We're seeing the limit hit in some tests after enabling sibling prerendering. Let's bump the limit so we can run more tests and gather more signal on the changes. When we understand the scope of the problem we can determine whether we need to change how the updates are counted in prerenders and/or fix specific areas of product code.
Over time the behavior of these two paths has converged to be essentially the same. So this merges them back into one function. This should save some code size and also make it harder for the behavior to accidentally diverge. (For the same reason, rolling out this change might expose some areas where we had already accidentally diverged.)
When a synchronous update suspends, and we prerender the siblings, the prerendering should be non-blocking so that we can immediately restart once the data arrives. This happens automatically when there's a Suspense boundary, because we immediately commit the boundary and then proceed to a Retry render, which are always concurrent. When there's not a Suspense boundary, there is no Retry, so we need to take care to switch from the synchronous work loop to the concurrent one, to enable time slicing.
…ectorDataForViewAtPoint (#31068) React DevTools no longer operates with just Fibers, it now builds its own Shadow Tree, which represents the tree on the Host (Fabric on Native, DOM on Web). We have to keep track of public instances for a select-to-inspect feature. We've recently changed this logic in #30831, and looks like we've been incorrectly getting a public instance for Fabric case. Not only this, turns out that all `getInspectorData...` APIs are returning Fibers, and not public instances. I have to expose it, so that React DevTools can correctly identify the element, which was selected. Changes for React Native are in [D63421463](https://www.internalfb.com/diff/D63421463)

`JSXMemberExpression` is currently the only instruction (that I know of) that directly references identifier lvalues without a corresponding `LoadLocal`. This has some side effects: - deadcode elimination and constant propagation now reach JSXMemberExpressions - we can delete `LoweredFunction.dependencies` without dangling references (previously, the only reference to JSXMemberExpression objects in HIR was in function dependencies) - JSXMemberExpression now is consistent with all other instructions (e.g. has a rvalue-producing LoadLocal) ' --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

…seActionException sentinel (#31554) This lets us track separately if something was suspended on an Action using useActionState rather than suspended on Data. This approach feels quite bloated and it seems like we'd eventually might want to read more information about the Promise that suspended and the context it suspended in. As a more general reason for suspending. The way useActionState works in combination with the prewarming is quite unfortunate because 1) it renders blocking to update the isPending flag whether you use it or not 2) it prewarms and suspends the useActionState 3) then it does another third render to get back into the useActionState position again.
This PR introduces a new experimental hook `useResourceEffect`, which is something that we're doing some very early initial tests on. This may likely not pan out and will be removed or modified if so. Please do not rely on it as it will break.
Since `enableRefAsProp` shipped everywhere, the ReactElement implementation on prod puts refs on both `element.ref` and `element.props.ref`. Here we let the `ref` case fall through so its now available on props, matching the JSX runtime.

…ded (#31552) When we suspend the render with delay, we won't do any more work until we get some kind of another update/ping. It's because conceptually something is suspended and then will update later. We need to highlight this period to show why it's not doing any work. We fill the empty space with "Suspended". This stops whenever the same lane group starts rendering again. Clamped by the preceeding start time/event time/update time. <img width="902" alt="Screenshot 2024-11-15 at 1 01 29 PM" src="https://github.com/user-attachments/assets/acf9dc9a-8fc3-4367-a8b0-d19f9c9eac73"> Ideally we would instead start the next render and suspend the work loop at all places we suspend. In that mode this will instead show up as a very long "Render" with a "Suspended" period instead highlighted in the Components track as one component is suspended. We'll soon have that for `use()` but not all updates so this covers the rest. One issue with `useActionState` is that it is implemented as suspending at the point of the `useActionState` which means that the period of the Action shows up as a suspended render instead of as an Action which happens for raw actions. This is not really how you conceptually think about it so we need some special case for `useActionState`. In the screenshot above, the first "Suspended" is actually awaiting an Action and the second "Suspended" is awaiting the data from it.
Stacked on #31552. Must be tested with `enableSiblingPrerendering` off since the `use()` optimization is not on there yet. This adds a span to the Components track when we yield in the middle of the event loop. In this scenario, the "Render" span continues through out the Scheduler track. So you can see that the Component itself might not take a long time but yielding inside of it might. This lets you see if something was blocking the React render loop while yielding. If we're blocked 1ms or longer we log that as "Blocked". If we're yielding due to suspending in the middle of the work loop we log this as "Suspended". <img width="837" alt="Screenshot 2024-11-16 at 1 15 14 PM" src="https://github.com/user-attachments/assets/45a858ea-17e6-416c-af1a-78c126e033f3"> If the render doesn't commit because it restarts due to some other prewarming or because some non-`use()` suspends, it doesn't have from context components. <img width="971" alt="Screenshot 2024-11-16 at 1 13 55 PM" src="https://github.com/user-attachments/assets/a67724f8-702e-4e7d-9499-9ffc09541a61"> The `useActionState` path doesn't work yet because the `use()` optimization doesn't work there for some reason. But the idea is that it should mark the time that the component is blocked as Action instead of Suspended.
Happens to the best of us.
Fixes a bug with the experimental `useResourceEffect` hook where we would compare the wrong deps when there happened to be another kind of effect preceding the ResourceEffect. To do this correctly we need to add a pointer to the ResourceEffect's identity on the update. I also unified the previously separate push effect impls for resource effects since they are always pushed together as a unit.
This avoid re-emitting the yellow "Event" log when we ping inside the original event. Instead of treating events as repeated when we get repeated updates, we treat them as repeated if we've ever logged out this event before. Additionally, in the case the prerender sibling flag is on we need to ensure that if a render gets interrupted when it has been suspended we treat that as "Prewarm" instead of "Interrupted Render". Before: <img width="539" alt="Screenshot 2024-11-19 at 2 39 44 PM" src="https://github.com/user-attachments/assets/190ca50c-5168-40d8-a6fd-6b9a583af1f0"> After: <img width="1004" alt="Screenshot 2024-11-21 at 4 53 16 PM" src="https://github.com/user-attachments/assets/0c441ada-1ed1-412c-8935-aaf040c25dfe">
This ensures that we mark the time from ping until we render as "Blocked". We intentionally don't want to show the event time even if it's something like "load" because it draws attention away from interactions etc. <img width="577" alt="Screenshot 2024-11-21 at 7 22 39 PM" src="https://github.com/user-attachments/assets/70cca2e8-bd5e-489f-98f0-b4dfee5940af">
This is for researching/prototyping, not a feature we are releasing imminently. Putting up an early version of inferring effect dependencies to get feedback on the approach. We do not plan to ship this as-is, and may not start by going after direct `useEffect` calls. Until we make that decision, the heuristic I use to detect when to insert effect deps will suffice for testing. The approach is simple: when we see a useEffect call with no dep array we insert the deps inferred for the lambda passed in. If the first argument is not a lambda then we do not do anything. This diff is the easy part. I think the harder part will be ensuring that we can infer the deps even when we have to bail out of memoization. We have no other features that *must* run regardless of rules of react violations. Does anyone foresee any issues using the compiler passes to infer reactive deps when there may be violations? I have a few questions: 1. Will there ever be more than one instruction in a block containing a useEffect? if no, I can get rid of the`addedInstrs` variable that I use to make sure I insert the effect deps array temp creation at the right spot. 2. Are there any cases for resolving the first argument beyond just looking at the lvalue's identifier id that I'll need to take into account? e.g., do I need to recursively resolve certain bindings? --------- Co-authored-by: Mofei Zhang <[email protected]>
This is a hack that ensures that all four lanes as visible whether you have any tracks in them or not, and that they're in the priority order within the Scheduler track group. We do want to show all even if they're not used because it shows what options you're missing out on. <img width="1035" alt="Screenshot 2024-11-22 at 12 38 30 PM" src="https://github.com/user-attachments/assets/f30ab0b9-af5e-48ed-b042-138444352575"> In Chrome, the order of tracks within a group are determined by the earliest start time. We add fake markers at start time zero in that order eagerly. Ideally we could do this only once but because calls that aren't recorded aren't considered for ordering purposes, we need to keep adding these over and over again in case recording has just started. We can't tell when recording starts. Currently performance.mark() are in first insertion order but performance.measure() are in the reverse order. I'm not sure that's intentional. We can always add the 0 time slot even if it's in the past. That's still considered for ordering purposes as long as the measurement is recorded at the time we call it.
A long standing issue for React has been that if you reorder stateful nodes, they may lose their state and reload. The thing moving loses its state. There's no way to solve this in general where two stateful nodes swap. The [`moveBefore()` proposal](https://chromestatus.com/feature/5135990159835136?gate=5177450351558656) has now moved to [intent-to-ship](https://groups.google.com/a/chromium.org/g/blink-dev/c/YE_xLH6MkRs/m/_7CD0NYMAAAJ). This function is kind of like `insertBefore` but preserves state. There's [a demo here](https://state-preserving-atomic-move.glitch.me/). Ideally we'd port this demo to a fixture so we can try it. Currently this flag is always off - even in experimental. That's because this is still behind a Chrome flag so it's a little early to turn it on even in experimental. So you need a custom build. It's on in RN but only because it doesn't apply there which makes it easier to tell that it's safe to ship once it's on everywhere else. The other reason it's still off is because there's currently a semantic breaking change. `moveBefore()` errors if both nodes are disconnected. That happens if we're inside a completely disconnected React root. That's not usually how you should use React because it means effects can't read layout etc. However, it is currently supported. To handle this we'd have to try/catch the `moveBefore` to handle this case but we hope this semantic will change before it ships. Before we turn this on in experimental we either have to wait for the implementation to not error in the disconnected-disconnected case in Chrome or we'd have to add try/catch.
We didn't originally support holes within array patterns, so DCE was only able to prune unused items from the end of an array pattern. Now that we support holes we can replace any unused item with a hole, and then just prune the items to the last identifier/spread entry. Note: this was motivated by finding useState where either the state or setState go unused — both are strong indications that you're violating the rules in some way. By DCE-ing the unused portions of the useState destructuring we can easily check if you're ignoring either value. closes #31603 This is a redo of that PR not using ghstack
It's tricky to do feature detection of uRC currently because it's always present on the export. Let's conditionally export it instead.
Adds a way to configure how we insert deps for experimental purposes.
```
[
{
module: 'react',
imported: 'useEffect',
numRequiredArgs: 1,
},
{
module: 'MyExperimentalEffectHooks',
imported: 'useExperimentalEffect',
numRequiredArgs: 2,
},
]
```
would insert dependencies for calls of `useEffect` imported from `react`
if they have 1 argument and calls of useExperimentalEffect` from
`MyExperimentalEffectHooks` if they have 2 arguments. The pushed dep
array is appended to the arg list.
