## Summary
When using ANSI escape sequences, we construct a message in the
following way: `console.<method>('\x1b...%s\x1b[0m',
userspaceArgument1?, userspaceArgument2?, userspaceArgument3?, ...)`.
This won't dim all arguments, if user had something like `console.log(1,
2, 3)`, we would only apply it to `1`, since this is the first
arguments, so we need to:
- inline everything whats possible into a single string, while
preserving console substitutions defined by the user
- omit css and object substitutions, since we can't really inline them
and will delegate in to the environment
## How did you test this change?
Added some tests, manually inspected that it works well for web and
native cases.
Adds fixtures for `macro.namespace(...)` style invocations which we use internally in some cases instead of just `macro(...)`. I tried every example i could think of that could possibly break it (including basing one off of another fixture where we hit an invariant related due to a temporary being emitted for a method call), and they all worked. I just had to fix an existing bug where we early return in some cases instead of continuing, which is a holdover from when this pass was originally written as a ReactiveFunction visitor.

## Summary
Removes the usage of `consoleManagedByDevToolsDuringStrictMode` flag
from React DevTools backend, this is the only place in RDT where this
flag was used. The only remaining part is
[`ReactFiberDevToolsHook`](6708115937/packages/react-reconciler/src/ReactFiberDevToolsHook.js (L203)),
so React renderers can start notifying DevTools when `render` runs in a
Strict Mode.
> TL;DR: it is broken, and we already incorrectly apply dimming, when
RDT frontend is not opened. Fixing in the next few changes, see next
steps.
Before explaining why I am removing this, some context is required. The
way RDT works is slightly different, based on the fact if RDT frontend
and RDT backend are actually connected:
1. For browser extension case, the Backend is a script, which is
injected by the extension when page is loaded and before React is
loaded. RDT Frontend is loaded together with the RDT panel in browser
DevTools, so ONLY when user actually opens the RDT panel.
2. For native case, RDT backend is shipped together with `react-native`
for DEV bundles. It is always injected before React is loaded. RDT
frontend is loaded only when user starts a standalone RDT app via `npx
react-devtools` or by opening React Native DevTools and then selecting
React DevTools panel.
When Frontend is not connected to the Backend, the only thing we have is
the `__REACT_DEVTOOLS_GLOBAL_HOOK__` — this thing inlines some APIs in
itself, so that it can work similarly when RDT Frontend is not even
opened. This is especially important for console logs, since they are
cached and stored, then later displayed to the user once the Console
panel is opened, but from RDT side, you want to modify these console
logs when they are emitted.
In order to do so, we [inline the console patching logic into the
hook](3ac551e855/packages/react-devtools-shared/src/hook.js (L222-L319)).
This implementation doesn't use the
`consoleManagedByDevToolsDuringStrictMode`. This means that if we enable
`consoleManagedByDevToolsDuringStrictMode` for Native right now, users
would see broken dimming in LogBox / Metro logs when RDT Frontend is not
opened.
Next steps:
1. Align this console patching implementation with the one in `hook.js`.
2. Make LogBox compatible with console stylings: both css and ASCII
escape symbols.
3. Ship new version of RDT with these changes.
4. Remove `consoleManagedByDevToolsDuringStrictMode` from
`ReactFiberDevToolsHook`, so this is rolled out for all renderers.
This adds few changes:
1. We are going to ship source maps only for 2 artifacts:
`installHook.js` and `react_devtools_backend_compact.js`, because it is
only these modules that can patch console and be visible to the user via
stack traces in console. We need to ship source maps to be able to use
`ignoreList` feature in source maps, so we can actually hide these from
stack traces.
| Before | After |
|--------|--------|
| 
| 
|
2. The `"sources"` field in source map will have relative urls listed,
instead of absolute with `webpack://` protocol. This will move the
sources to the `React Developer Tools` frame in `Sources` panel, instead
of `webpack://`.
| Before | After |
|--------|--------|
| 
| 
|
> [!NOTE]
> I still have 1 unresolved issue with shipping source maps in extension
build, and it is related to Firefox, which can't find them in the
extension bundle and returns 404, even though urls are relative and I
can actually open them via unique address like
`moz-extension://<extension-id>/build/intallHook.js.map` ¯\\\_(ツ)\_/¯
## Summary
Configures the React Native open source feature flags in preparation for
React Native 0.75, which will be upgraded to React 19.
## How did you test this change?
```
$ yarn test
$ yarn flow fabric
```
Adds a pass just after DCE to reorder safely reorderable instructions (jsx, primitives, globals) closer to where they are used, to allow other optimization passes to be more effective. Notably, the reordering allows scope merging to be more effective, since that pass relies on two scopes not having intervening instructions — in many cases we can now reorder such instructions out of the way and unlock merging, as demonstrated in the changed fixtures.
The algorithm itself is described in the docblock.
note: This is a cleaned up version of #29579 that is ready for review.

Pull Request resolved: https://github.com/facebook/react/pull/29863
Updates our scope merging pass to allow more types of instructions to intervene btw scopes. This includes all the non-allocating kinds of nodes that are considered reorderable in #29863. It's already safe to merge scopes with these instructions — we only merge if the lvalue is not used past the next scope. Additionally, without changing this pass reordering isn't very effective, since we would reorder to add these types of intervening instructions and then not be able to merge scopes.
Sequencing this first helps to see the win just from reordering alone.

## Summary
<!--
Explain the **motivation** for making this change. What existing problem
does the pull request solve?
-->
In the Fabric renderer in React Native, we only use the HostContext to
issue soft errors in __DEV__ bundles when attempting to add a raw text
child to a node that may not support them. Moving the logic to set this
context to __DEV__ bundles only unblocks more expensive methods for
resolving whether a parent context supports raw text children, like
resolving this information from `getViewConfigForType`.

sanitize javascript: urls for <object> tags
React 19 added sanitization for `javascript:` URLs for `href` properties
on various tags. This PR also adds that sanitization for `<object>` tags
as well that Firefox otherwise executes.
Summary: The change detection mode was unavailable in the playground because the pragma was not a boolean. This fixes that by special casing it in pragma parsing, similar to validateNoCapitalizedCalls

### Summary
Similarly to what has been done on the `react-native` repo in
https://github.com/facebook/react-native/pull/43851, this PR adds a
`react.code-workspace` workspace file when using VSCode.
This disables the built-in TypeScript Language Service for `.js`, `.ts`,
and `.json` files, recommends extensions, enables `formatOnSave`,
excludes certain files in search, and configures Flow language support.
### Motivation
This is a DevX benefit for **React contributors** using open source VS
Code. Without this, it takes quite a long time to set up the environment
in vscode to work well.
For me the following two points took around an hour each to figure out,
but for others it may take even more (screenshots can be found below):
* Search with "files to include" was searching in ignored files
(compiled/generated)
* Configure language validation and prettier both in "packages" that use
flow and in the "compiler" folder that uses typescript.
### Recommended extensions
NOTE: The recommended extensions list is currently minimal — happy to
extend this now or in future, but let's aim to keep these conservative
at the moment.
* Flow — language support
* EditorConfig — formatting based on `.editorconfig`, all file types
* Prettier — formatting for JS* files
* ESLint — linter for JS* files
### Why `react.code-workspace`?
`.code-workspace` files have slight extra behaviours over a `.vscode/`
directory:
* Allows user to opt-in or skip.
* Allows double-click launching from file managers.
* Allows base folder (and any subfolders in future) to be opened with
local file tree scope (useful in fbsource!)
* (Minor point) Single config file over multiple files.

### Test plan
Against a new un-configured copy of Visual Studio Code Insiders.
**Without workspace config**
❌ .js files raise errors by default (built-in TypeScript language
service)
❌ When using the Flow VS Code extension, the wrong version (global) of
Flow is used.

Pull Request resolved: https://github.com/facebook/react/pull/29884
Summary: Minor change inspired by #29863: the BuildHIR pass ensures that Binary and UnaryOperator nodes only use a limited set of the operators that babel's operator types represent, which that pr relies on for safe reorderability, but the type of those HIR nodes admits the other operators. For example, even though you can't build an HIR UnaryOperator with `delete` as the operator, it is a valid HIR node--and if we made a mistaken change that let you build such a node, it would be unsafe to reorder.
This pr makes the typing of operators stricter to prevent that.

The export maps for react packages have to choose an order of
preference. Many runtimes use multiple conditions, for instance when
building for edge webpack also uses the browser condition which makes
sense given most edge runtimes have a web-standards based set of APIs.
However React is building the browser builds primarily for actual
browsers and sometimes have builds intended for servers that might be
browser compat. This change updates the order of conditions to
preference specific named runtimes > node > generic edge runtimes >
browser > default
Fixes a bug found by mofeiZ in #29878. When we merge queued states, if the new state does not introduce changes relative to the queued state we should use the queued state, not the new state.

That way we get owner stacks (native or otherwise) for `console.error`
or `console.warn` inside of them.
Since the `reportError` is also called within this context, we also get
them for errors thrown within event listeners. You'll also be able to
observe this in in the `error` event. Similar to how `onUncaughtError`
is in the scope of the instance that errored - even though
`onUncaughtError` doesn't kick in for event listeners.

(This is the parent stack since React DevTools doesn't just yet print
owner stack.)
(Firefox doesn't print the component stack for uncaught since we don't
add component stacks for "error" events from React DevTools - just
console.error. Perhaps an oversight.)
If we didn't have the synthetic event system this would kind of just
work natively in Chrome because we have this task active when we attach
the event listeners to the DOM node and async stacks just follow along
that way. In fact, if you attach a manual listener in useEffect you get
this same effect. It's just because we use event delegation that this
doesn't work.
However, if we did get rid of the synthetic event system we'd likely
still want to add a wrapper on the DOM node to set our internal current
owner so that the non-native part of the system still can observe the
active instance. That wouldn't work with manually attached listeners
though.

This lets the environment name vary within a request by the context a
component, log or error being executed in.
A potentially different API would be something like
`setEnvironmentName()` but we'd have to extend the `ReadableStream` or
something to do that like we do for `.allReady`. As a function though it
has some expansion possibilities, e.g. we could potentially also pass
some information to it for context about what is being asked for.
If it changes before completing a task, we also emit the change so that
we have the debug info for what the environment was before entering a
component and what it was after completing it.
Stacked on #29807.
This lets the nearest Suspense/Error Boundary handle it even if that
boundary is defined by the model itself.
It also ensures that when we have an error during serialization of
properties, those can be associated with the nearest JSX element and
since we have a stack/owner for that element we can use it to point to
the source code of that line. We can't track the source of any nested
arbitrary objects deeper inside since objects don’t track their stacks
but close enough. Ideally we have the property path but we don’t have
that right now. We have a partial in the message itself.
<img width="813" alt="Screenshot 2024-06-09 at 10 08 27 PM"
src="https://github.com/facebook/react/assets/63648/917fbe0c-053c-4204-93db-d68a66e3e874">
Note: The component name (Counter) is lost in the first message because
we don't print it in the Task. We use `"use client"` instead because we
expect the next stack frame to have the name. We also don't include it
in the actual error message because the Server doesn't know the
component name yet. Ideally Client References should be able to have a
name. If the nearest is a Host Component then we do use the name though.
However, it's not actually inside that Component that the error happens
it's in App and that points to the right line number.
An interesting case is that if something that's actually going to be
consumed by the props to a Suspense/Error Boundary or the Client
Component that wraps them fails, then it can't be handled by the
boundary. However, a counter intuitive case might be when that's on the
`children` props. E.g.
`<ErrorBoundary>{clientReferenceOrInvalidSerialization}</ErrorBoundary>`.
This value can be inspected by the boundary so it's not safe to pass it
so if it's errored it is not caught.
## Implementation
The first insight is that this is best solved on the Client rather than
in the Server because that way it also covers Client References that end
up erroring.
The key insight is that while we don't have a true stack when using
`JSON.parse` and therefore no begin/complete we can still infer these
phases for Elements because the first child of an Element is always
`'$'` which is also a leaf. In depth first that's our begin phase. When
the Element itself completes, we have the complete phase. Anything in
between is within the Element.
Using this idea I was able to refactor the blocking tracking mechanism
to stash the blocked information on `initializingHandler` and then on
the way up do we let whatever is nearest handle it - whether that's an
Element or the root Chunk. It's kind of like an Algebraic Effect.
cc @unstubbable This is something you might want to deep dive into to
find more edge cases. I'm sure I've missed something.

Stacked on #29807.
Conceptually the error's owner/task should ideally be captured when the
Error constructor is called but neither `console.createTask` does this,
nor do we override `Error` to capture our `owner`. So instead, we use
the nearest parent as the owner/task of the error. This is usually the
same thing when it's thrown from the same async component but not if you
await a promise started from a different component/task.
Before this stack the "owner" and "task" of a Lazy that errors was the
nearest Fiber but if the thing erroring is a Server Component, we need
to get that as the owner from the inner most part of debugInfo.
To get the Task for that Server Component, we need to expose it on the
ReactComponentInfo object. Unfortunately that makes the object not
serializable so we need to special case this to exclude it from
serialization. It gets restored again on the client.

Summary: We now expect that candidate components that have Flow or TS type annotations on their first parameters have annotations that are potentially objects--this lets us reject compiling functions that explicitly take e.g. `number` as a parameter.

Summary: We can tighten our criteria for what is a component by requiring that a component or hook contain JSX or hook calls directly within its body, excluding nested functions . Currently, if we see them within the body anywhere -- including nested functions -- we treat it as a component if the other requirements are met. This change makes this stricter.
We also now expect components (but not necessarily hooks) to have return statements, and those returns must be potential React nodes (we can reject functions that return function or object literals, for example).

Stacked on #29804.
Transferring of debugInfo was added in #28286. It represents the parent
stack between the current Fiber and into the next Fiber we're about to
create. I.e. Server Components in between. ~I don't love passing
DEV-only fields as arguments anyway since I don't trust closure to
remove unused arguments that way.~ EDIT: Actually it seems like closure
handled that just fine before which is why this is no change in prod.
Instead, I track it on the module scope. Notably with DON'T use
try/finally because if something throws we want to observe what it was
at the time we threw. Like the pattern we use many other places.
Now we can use this when we create the Throw Fiber to associate the
Server Components that were part of the parent stack before this error
threw. There by giving us the correct parent stacks at the location that
threw.
This lets us rethrow it in the conceptual place of the child.
There's currently a problem when we suspend or throw in the child fiber
reconciliation phase. This work is done by the parent component, so if
it suspends or errors it is as if that component errored or suspended.
However, conceptually it's like a child suspended or errored.
In theory any thing can throw but it is really mainly due to either
`React.lazy` (both in the element.type position and node position),
`Thenable`s or the `Thenable`s that make up `AsyncIterable`s.
Mainly this happens because a Server Component that errors turns into a
`React.lazy`. In practice this means that if you have a Server Component
as the direct child of an Error Boundary. Errors inside of it won't be
caught.
We used to have the same problem with Thenables and Suspense but because
it's now always nested inside an inner Offscreen boundary that shields
it by being one level nested. However, when we have raw Offscreen
(Activity) boundaries they should also be able to catch the suspense if
it's in a hidden state so the problem returns. This fixes it for thrown
promises but it doesn't fix it for SuspenseException. I'm not sure this
is even the right strategy for Suspense though. It kind of relies on the
node never actually mounting/committing.
It's conceptually a little tricky because the current component can
inspect the children and make decisions based on them. Such as
SuspenseList.
The other thing that this PR tries to address is that it sets the
foundation for dealing with error reporting for Server Components that
errored. If something client side errors it'll be a stack like Server
(DebugInfo) -> Fiber -> Fiber -> Server -> (DebugInfo) -> Fiber.
However, all error reporting relies on it eventually terminating into a
Fiber that is responsible for the error. To avoid having to fork too
much it would be nice if I could create a Fiber to associate with the
error so that even a Server component error in this case ultimately
terminates in a Fiber.
We know from Fiber that inline objects with more than 16 properties in
V8 turn into dictionaries instead of optimized objects. The trick is to
use a constructor instead of an inline object literal. I don't actually
know if that's still the case or not. I haven't benchmarked/tested the
output. Better safe than sorry.
It's unfortunate that this can have a negative effect for Hermes and JSC
but it's not as bad as it is for V8 because they don't deopt into
dictionaries. The time to construct these objects isn't a concern - the
time to access them frequently is.
We have to beware the Task objects in Fizz. Those are currently on 16
fields exactly so we shouldn't add anymore ideally.
We should ideally have a lint rule against object literals with more
than 16 fields on them. It might not help since sometimes the fields are
conditional.
To keep consistent with the rest of the React repo, let's remove this
because editor settings are personal. Additionally this wasn't in the
root directory so it wasn't being applied anyway.

Per title, implements an HIR-based version of FlattenScopesWithHooksOrUse as part of our push to use HIR everywhere. This is the last pass to migrate before PropagateScopeDeps, which is blocking the fix for `bug.invalid-hoisting-functionexpr`, ie where we can infer incorrect dependencies for function expressions if the dependencies are accessed conditionally.

Pre the title, this implements an HIR-based version of FlattenReactiveLoops. Another step on the way to HIR-everywhere.

Adds the HIR equivalent of a pruned-scope, allowing us to start porting the scope-pruning passes to operate on HIR.

## Summary
<!--
Explain the **motivation** for making this change. What existing problem
does the pull request solve?
-->
The parsePluginOptions seemed to be duplicated within
[BabelPlugin.ts](f5af92d2c4/compiler/packages/babel-plugin-react-compiler/src/Babel/BabelPlugin.ts (L32))
and
[Program.ts](f5af92d2c4/compiler/packages/babel-plugin-react-compiler/src/Entrypoint/Program.ts (L220)).
Since the options already parsed in BabelPlugin.ts should have been
passed to compileProgram, in this PR we deleted parsePluginOptions in
compileProgram and used the options passed as arguments as they are.
I've done that.
## How did you test this change?
<!--
Demonstrate the code is solid. Example: The exact commands you ran and
their output, screenshots / videos if the pull request changes the user
interface.
How exactly did you verify that your PR solves the issue you wanted to
solve?
If you leave this empty, your PR will very likely be closed.

Basically make `console.error` and `console.warn` behave like normal -
when a component stack isn't appended. I need this because I need to be
able to print rich logs with the component stack option and to be able
to disable instrumentation completely in `console.createTask`
environments that don't need it.
Currently we can't print logs with richer objects because they're
toString:ed first. In practice, pretty much all arguments we log are
already toString:ed so it's not necessary anyway. Some might be like a
number. So it would only be a problem if some environment can't handle
proper consoles but then it's up to that environment to toString it
before logging.
The `Warning: ` prefix is historic and is both noisy and confusing. It's
mostly unnecessary since the UI surrounding `console.error` and
`console.warn` tend to have visual treatment around it anyway. However,
it's actively misleading when `console.error` gets prefixed with a
Warning that we consider an error level. There's an argument to be made
that some of our `console.error` don't make the bar for an error but
then the argument is to downgrade each of those to `console.warn` - not
to brand all our actual error logging with `Warning: `.
Apparently something needs to change in React Native before landing this
because it depends on the prefix somehow which probably doesn't make
sense already.
