* Basic partial hydration test
* Render comments around Suspense components
We need this to be able to identify how far to skip ahead if we're not
going to hydrate this subtree yet.
* Add DehydratedSuspenseComponent type of work
Will be used for Suspense boundaries that are left with their server
rendered content intact.
* Add comment node as hydratable instance type as placeholder for suspense
* Skip past nodes within the Suspense boundary
This lets us continue hydrating sibling nodes.
* A dehydrated suspense boundary comment should be considered a sibling
* Retry hydrating at offscreen pri or after ping if suspended
* Enter hydration state when retrying dehydrated suspense boundary
* Delete all children within a dehydrated suspense boundary when it's deleted
* Delete server rendered content when props change before hydration completes
* Make test internal
* Wrap in act
* Change SSR Fixture to use Partial Hydration
This requires the enableSuspenseServerRenderer flag to be manually enabled
for the build to work.
* Changes to any parent Context forces clearing dehydrated content
We mark dehydrated boundaries as having child work, since they might have
components that read from the changed context.
We check this in beginWork and if it does we treat it as if the input
has changed (same as if props changes).
* Wrap in feature flag
* Treat Suspense boundaries without fallbacks as if not-boundaries
These don't come into play for purposes of hydration.
* Fix clearing of nested suspense boundaries
* ping -> retry

This is the minimum integration between Scheduler and React needed to
unblock use of the Scheduler.next API.

* hi andrew
(prettier fix)
* Avoid importing Scheduler directly
The reconciler should not depend directly on Scheduler. This adds it to
the host config for the renderer instead.
(Except for `scheduler/tracing` imports, which are used only by the
profiling build. I've left those imports as-is, though I'm open to
directing those through the host config, too.)
* Make throwaway root id longer to appease Brian
* Restrict effect return type to a function or nothing
We already warn in dev if the wrong type is returned. This updates the
Flow type.
* Restrict return type further
* Assume Effect hook returns either a function or undefined
* Tweak warning message
* Improve Reducer Hook's lazy init API
* Use generic type for initilizer input
Still requires an `any` cast in the case where `init` function is
not provided.
* Move DEV-only function right above where it's used
I don't like looking at this top-level function #petty
* Use different dispatchers for functions & classes
Classes support readContext, but not any of the other dispatcher
methods. Function support all methods.
This is a more robust version of our previous strategy of checking
whether `currentlyRenderingFiber` is null.
As a next step, we can use a separate dispatcher for each phase of the
render cycle (mount versus update).
* Use separate dispatchers for mount and update
* Remove mount code from update path
Deletes mount-specific code from the update path, since it should be
unreachable. To continue supporting progressive enhancement (mounting
new hooks at the end of the list), we detect when there are no more
current hooks and switch back to the mount dispatcher. Progressive
enhancement isn't officially supported yet, so it will continue to warn.
* Factoring nits
* Fix Flow
Had to cheat more than I would like
* More Flow nits
* Switch back to using a special dispatcher for nested hooks in DEV
In order for this strategy to work, I had to revert progressive
enhancement support (appending hooks to the end). It was previously a
warning but now it results in an error. We'll reconsider later.
* Always pass args to updateState and updateReducer
Even though the extra args are only used on mount, to ensure
type consistency.
* Make readContext() in Hooks DEV-only warning
* Warn about readContext() during class render-phase setState()
* Warn on readContext() in SSR inside useMemo and useReducer
* Make all Hooks-in-Hooks warnings DEV-only
* Rename stashContextDependencies
* Clean up warning state on errors
* Turned enableHooks feature flag on everywhere
* Removed useHooks feature flag from tests (now that it's on by default)
* Remove useHooks feature flag entirely
* Revert "Revert "Double-render function components with Hooks in DEV in StrictMode" (#14652)"
This reverts commit 3fbebb2a0b.
* Revert "Revert "Disallow reading context during useMemo etc" (#14651)"
This reverts commit 5fce6488ce.
* Add extra passing test for an edge case
Mentioned by @acdlite to watch out for
* More convoluted test
* Don't rely on expirationTime
Addresses @acdlite's concerns
* Edge case: forbid readContext() during eager reducer
