Merged master and resolved useEvent conflicts I am being a little lazy here and merging instead of rebasing because practically every commit conflicted with Dominic's recent useEvent PR. If anyone feel strongly about this, I will revert the commit and...

Added new failing tests (pending a separate fix to React)

Added new failing tests (pending a separate fix to React)

Replaced .warn() with .error() for mutable source unsubscribe check

Misc. cleanup 1. Use currentlyRenderingFiber to calculate expiration time rather than using a ref. 2. Use polyfilled is() rather than Object.is() 3. Add __EXPERIMENTAL__ guard to test since new APIs aren't in stable build 4. Removed error code that wa...

Defer getWorkInProgressRoot() call unless root is needed

Removed createMutableSource and useMutableSource exports from React stable release

Reenabled a pending disabled mutable source test

Whitespace only change

Misc. cleanup 1. Reset mutable source WIP version in complete and unwind work (rather than prepare fresh stack). 2. Add check to warn about multiple primary/secondary renderers using the same mutable source. (Patterned after our current context warnin...

Removed unused 'isMount' param from uMS

Pass underlying source to getVersion fn

Always treat reads from source as unsafe when getSnapshot changes I initially thought that we could treat them as safe if the returned snapshot value was the same, but this ignored the case where the underlying source was mutated between when the stat...

Handle mutations that occur between scheduled updates and render

Always reset state queue when getSnapshot changes Even if the current snapshot value is the same, there may be pending, lower priority updates that we no longer want to eventually render.

Use a second effect to sync getSnapshot and stateHook values on commit This prevents the subscription callback from closing over stale values.

Added a (disabled) test to cover uSM throwing during sync update

Refactor useMutableSource to be more efficient Remove unnecessary useRef in favor of hook state. Directly mutate composed state hook queue to reset in the case of a new subscribe or source.

Split useMutableSource tests into separate suite

Read mutable source composed hooks from current dispatcher Rather than passing them in explicitly. This removes the extra function call.

Avoid deopt on changed getSnapshot function unless snapshot also changes getSnapshot should be memoized to only change when its inputs change, but if that memoization is done incorrectly (or if the new snapshot just happens to be the same regardless o...

Fixed a typo/bug in setState updater function

Refactored useMutableSource to use update queue For now, the hook just uses useEffect and useState under the hood. This probably makes it a little less effcient at runtime but perhaps a little smaller in code size. This change ended up being a little...

useMutableSource hook useMutableSource() enables React components to safely and efficiently read from a mutable external source in Concurrent Mode. The API will detect mutations that occur during a render to avoid tearing and it will automatically sch...

Refactored API to remove config in favor of directly passing functions

Check version before snapshot on commit We need to schedule a cascading update if source changes between render and commit, but it's probably faster to check version than snapshot, so let's at least check it first.

Added TODO for partial renderer

Changed Flow syntax that was causing invalid build syntax

Replaced Error constructor with invariant

Refactored hook to reflect changes in RFC

Removed DEV warnings; they didn't follow precedent set by other hooks.
