* 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
* Revert "Revert "Dispatch commands to both UIManagers from both renderers (#17211)" (#17232)"
This reverts commit c443904b55.
* Clean up another __DEV__ warning check
* Replace all warning/lowPriWarning with console calls
* Replace console.warn/error with a custom wrapper at build time
* Fail the build for console.error/warn() where we can't read the stack
* prep for codemod
* prep warnings
* rename lint rules
* codemod for ifs
* shim www functions
* Handle more cases in the transform
* Thanks De Morgan
* Run the codemod
* Delete the transform
* Fix up confusing conditions manually
* Fix up www shims to match expected API
* Also check for low-pri warning in the lint rule
* Replace Babel plugin with an ESLint plugin
* Fix ESLint rule violations
* Move shared conditions higher
* Test formatting nits
* Tweak ESLint rule
* Bugfix: inside else branch, 'if' tests are not satisfactory
* Use a stricter check for exactly if (__DEV__)
This makes it easier to see what's going on and matches dominant style in the codebase.
* Fix remaining files after stricter check
* Remove "Invariant Violation" from dev errors
When I made the change to compile `invariant` to throw expressions, I
left a small runtime to set the error's `name` property to "Invariant
Violation" to maintain the existing behavior.
I think we can remove it. The argument for keeping it is to preserve
continuity in error logs, but this only affects development errors,
anyway: production error messages are replaced with error codes.
* Pass prod error messages directly to constructor
Updates the `invariant` transform to pass an error message string
directly to the Error constructor, instead of mutating the
message property.
Turns this code:
```js
invariant(condition, 'A %s message that contains %s', adj, noun);
```
into this:
```js
if (!condition) {
throw Error(
__DEV__
? `A ${adj} message that contains ${noun}`
: formatProdErrorMessage(ERR_CODE, adj, noun)
);
}
```
* Add Event Replaying Infra
* Wire up Roots and Suspense boundaries, to retry events, after they commit
* Replay discrete events in order in a separate scheduler callback
* Add continuous events
These events only replay their last target if the target is not yet
hydrated. That way we don't have to wait for a previously hovered
boundary before invoking the current target.
* Enable tests from before
These tests were written with replaying in mind and now we can properly
enable them.
* Unify replaying and dispatching
* Mark system flags as a replay and pass to legacy events
That way we can check if this is a replay and therefore needs a special
case. One such special case is "mouseover" where we check the
relatedTarget.
* Eagerly listen to all replayable events
To minimize breakages in a minor, I only do this for the new root APIs
since replaying only matters there anyway. Only if hydrating.
For Flare, I have to attach all active listeners since the current
system has one DOM listener for each. In a follow up I plan on optimizing
that by only attaching one if there's at least one active listener
which would allow us to start with only passive and then upgrade.
* Desperate attempt to save bytese
* Add test for mouseover replaying
We need to check if the "relatedTarget" is mounted due to how the old
event system dispatches from the "out" event.
* Fix for nested boundaries and suspense in root container
This is a follow up to #16673 which didn't have a test because it wasn't
observable yet. This shows that it had a bug.
* Rename RESPONDER_EVENT_SYSTEM to PLUGIN_EVENT_SYSTEM
Real Maps should now be used in RN JS engines. In theory this should
be faster (but might not actually be in practice), and it avoids hitting
upper bounds of property max counts.
We don't use these types of Maps in Fabric.
