* Add options for forked entry points
We currently fork .fb.js entry points. This adds a few more options.
.modern.fb.js - experimental FB builds
.classic.fb.js - stable FB builds
.fb.js - if no other FB build, use this for FB builds
.experimental.js - experimental builds
.stable.js - stable builds
.js - used if no other override exists
This will be used to have different ES exports for different builds.
* Switch React to named exports
* Export named exports from the export point itself
We need to re-export the Flow exported types so we can use them in our code.
We don't want to use the Flow types from upstream since it doesn't have the non-public APIs that we have.
This should be able to use export * but I don't know why it doesn't work.
This actually enables Flow typing of React which was just "any" before.
This exposed some Flow errors that needs fixing.
* Create forks for the react entrypoint
None of our builds expose all exports and they all differ in at least one
way, so we need four forks.
* Set esModule flag to false
We don't want to emit the esModule compatibility flag on our CommonJS
output. For now we treat our named exports as if they're CommonJS.
This is a potentially breaking change for scheduler (but all those apis
are unstable), react-is and use-subscription. However, it seems unlikely
that anyone would rely on this since these only have named exports.
* Remove unused Feature Flags
* Let jest observe the stable fork for stable tests
This lets it do the negative test by ensuring that the right tests fail.
However, this in turn will make other tests that are not behind
__EXPERIMENTAL__ fail. So I need to do that next.
* Put all tests that depend on exports behind __EXPERIMENTAL__
Since there's no way to override the exports using feature flags
in .intern.js anymore we can't use these APIs in stable.
The tradeoff here is that we can either enable the negative tests on
"stable" that means experimental are expected to fail, or we can disable
tests on stable. This is unfortunate since some of these APIs now run on
a "stable" config at FB instead of the experimental.
* Switch ReactDOM to named exports
Same strategy as React.
I moved the ReactDOMFB runtime injection to classic.fb.js
Since we only fork the entrypoint, the `/testing` entrypoint needs to
be forked too to re-export the same things plus `act`. This is a bit
unfortunate. If it becomes a pattern we can consider forking in the
module resolution deeply.
fix flow
* Fix ReactDOM Flow Types
Now that ReactDOM is Flow type checked we need to fix up its types.
* Configure jest to use stable entry for ReactDOM in non-experimental
* Remove additional FeatureFlags that are no longer needed
These are only flagging the exports and no implementation details so we
can control them fully through the export overrides.
* import * as React from "react";
This is the correct way to import React from an ES module since the ES
module will not have a default export. Only named exports.
* import * as ReactDOM from "react-dom"
* apply changes on editablevalue on blur feature implemented
* Removed "Undo" button and unnecessary event.preventDefault()

Update various parts of DevTools to account for the fact that the global "hook" might be undefined if DevTools didn't inject it (due to the page's `contentType`) it (due to the page's `contentType`)
* Update Flow to 0.84
* Fix violations
* Use inexact object syntax in files from fbsource
* Fix warning extraction to use a modern parser
* Codemod inexact objects to new syntax
* Tighten types that can be exact
* Revert unintentional formatting changes from codemod
Previously, DevTools filtered empty commits on the backend, while profiling, through the use of a bailout heuristic that React currently happens to use. This approach was brittle and may have exacerbated the long-standing Profiler bug #16446.
This PR removes that heuristic and adds as a post-processing filtering pass instead. This removes the coupling between DevTools and a React internal implementation detail that may change.
I believe DevTools has two choices of criteria for this filtering:
* Filter commits that have no actual duration metadata.
* Filter commits that have no recorded operations (no mutations to the tree, no changed tree base durations).
I chose the first option, filtering by commits that have no reported metadata. It will miss an edge case, e.g. , but we would have nothing meaningful to show in the Profiler for those cases anyway. (This particular edge case is why one of the snapshots changed with this commit.)
The second option, filtering by recorded operations, could potentially miss a more important edge case: where a component *did* render, but its didn't change. (In that event, there would be no operations to send.)
DevTools previously called in several places with user-defined values. This could lead to runtime errors if those values had an overriden attribute. This commit replaces those callse with instead.
New test cases have been added.
The Profiler stores:
1. A snapshot of the React tree when profiling started
2. The operations array for each commit
3. Profiling metadata (e.g. durations, what changed, etc) for each commit
It uses this information (snapshot + operations diff) to reconstruct the state of the application for a given commit as it's viewed in the Profiler UI. Because of this, it's very important that the operations and metadata arrays align. If they don't align, the profiler will be unable to correctly reconstruct the tree, and it will likely throw errors (like 'Could not find node…')
#16446 tracks a long-standing bug where these two arrays get misaligned. I am still not entirely sure what causes this bug, but with PR #17253, I exacerbated things by introducing another potential way for it to happen. This PR addresses the regression at least (and adds test coverage for it).
I will follow up this afternoon on the original #16446 issue. I think I may have a lead on what's happening at least, if not exactly an idea of how to reproduce it.
I used to disable the <- and -> buttons when you reached the beginning or end of the profiler data. This can be kind of annoying though when you just want to get to the last commit, and I don't think there's a good reason to enforce it anyway, so I backed that change out. The buttons now wrap around at the beginning or end of the list.
The param should probably be a generic type, but I'm not sure how to satisfy Flow with the current top-level Map. At least this adds basic coverage (which was missing before, oops).
Previously, when props/state contained a regexp, it was shown as an
empty object. This commit adds regexps as values in need of special
rehydration (like Symbols or TypedArrays), and display them as a user
might expect.

* Added rudimentary context menu hook and menu UI
* Added backend support for copying a value at a specific path for the inspected element
* Added backend support for storing a value (at a specified path) as a global variable
* Added special casing to enable copying undefined/unserializable values to the clipboard
* Added copy and store-as-global context menu options to selected element props panel
* Store global variables separately, with auto-incremented name (like browsers do)
* Added tests for new copy and store-as-global backend functions
* Fixed some ownerDocument/contentWindow edge cases
* Refactored context menu to support dynamic options
Used this mechanism to add a conditional menu option for inspecting the current value (if it's a function)
* Renamed "safeSerialize" to "serializeToString" and added inline comment
* fix(dev-tools): fix show correct displayName with forwardRef in Dev Tools
allow set `displayName` after `React.forwardRef()`,
makesure Dev Tools show displayName as same as `getWrappedName` in `shared/getComponentName.js`
* Removed a little unnecessary/redundant code.
* Fixed lint error (removed unused var)
1. Enable nested values to be expanded/collapsed by clicking on values as well as keys.
2. Enable keys and values to be selectable (for copy-pasting purposes)
* Skip abandoned project folders in Jest config
This fixes a problem that occurs after renaming a package.
* Fix test_build_devtools to run test-build-devtools
* Exclude console.error plugin for DevTools packages
* Use correct release channel for DevTools tests
This should fix the createRoot error.
* Fix TZ dependent test
* Change DT job dependencies
* Improved inspected element props with inline previews
This mimics the inline preview shown by the brower console and dramatically improves the UX when inspecting deep values. I also updated tests to add more coverage for this new functionality.
* Cleaned up the DataView vs typed array check
* Added early bailouts to DevTools when generating preview strings for iterables/objects/arrays, to avoid doing unnecessary work
* fix: make serializable data for bridge in react-devtools
* fix: add bigint data type in hydration
* refactor: remove console.log
* test: update unit tests for bigint in react-devtools
1. Add a Store test for memo, lazy, and forwardRef components
2. Remove dead code for React.lazy
3. Update DT tests to include HOC badge names in the serialized store
* [react-is] return correct typeOf value of forwardRef
* [react-devtools-shared] use correct displayName of memo(forwardRef(Component))
* [react-devtools-shared] add resolveFiberType and resolve fiber type of memo recursively
Resolving the fiber type of memo recursively before passing it to getDisplayName
will prevent it from displaying "Anonymous" as displayName for components
wrapped with both memo and forwardRef: memo(forwardRef(Component))
* rework resolveFiberType
* SuspenseList support in DevTools
This adds SuspenseList tags to DevTools so that the name properly shows
up.
It also switches to use the tag instead of Symbol type for Suspense
components. We shouldn't rely on the type for any built-ins since that
field will disappear from the fibers. How the Fibers get created is an
implementation detail that can change e.g. with a compiler or if we
use instanceof checks that are faster than symbol comparisons.
* Add SuspenseList test to shell app
* Tests run in experimental mode by default
For local development, you usually want experiments enabled. Unless
the release channel is set with an environment variable, tests will
run with __EXPERIMENTAL__ set to `true`.
* Remove concurrent APIs from stable builds
Those who want to try concurrent mode should use the experimental
builds instead.
I've left the `unstable_` prefixed APIs in the Facebook build so we
can continue experimenting with them internally without blessing them
for widespread use.
* Turn on SSR flags in experimental build
* Remove prefixed concurrent APIs from www build
Instead we'll use the experimental builds when syncing to www.
* Remove "canary" from internal React version string
