* Warn if unmounting a non-container
* Warn if the 2nd+ child is a "root" element but not first
This triggers our non-reuse mode. This is covered by ReactMount already but
the test doesn't pass yet without also landing #10026.
Simplifies markup generation by only inserting a simple comments between
consecutive text nodes.
I also skip past comments and other nodes while hydrating. This leaves them
in place instead of being removed by the hydration mechanism. This is more
efficient but will also be needed by hydration validator.
There's a special case for empty strings. We probably shouldn't have nodes
for those at all. For now I special case it by assuming there won't be one
so if we need one, we'll insert an empty text node.
I also dropped the ID from the react ID.
This covers up errors that are thrown in Fiber, because callback gets
fired *and* an error is thrown. Created a follow up #10049 to reevaluate
these semantics.
# Conflicts:
# scripts/fiber/tests-passing-except-dev.txt
# scripts/fiber/tests-passing.txt
This ensures that custom properties that are required by Facebook's error tooling (eg 'framesToPop') don't get dropped.
I also improved the handling/messaging of thrown strings.
There's no advantage to scheduling updates with animation priority
versus scheduling sync work inside requestAnimationCallback. So we can
remove all the animation-specific code. Now there's only one type of
callback.
Allows us to make assertions on the values that are yielded when
performing work. In our existing tests, we do this manually by pushing
into an array.
ReactNoop.flushThrough extends this concept. It accepts an array of
expected values and flushes until those values are yielded.
When a user types an emoji via Touch keyboard in IE, React's fallback logic
creates the `BeforeInput` event based on the `keypress`. However, the length
of an emoji character (e.g. `\uD83D\uDE0A`) is two, so the `which` property
does not represent an emoji correctly.
Because IE's KeyboardEvent has the `char` property holding an entire emoji,
we can use it directly instead of converting from the `which`.
This makes it so you don't need to pattern-match manually to build a renderer where the container and instance types are not the same. Prerequisite to #9835.
* Prevents adding units to css custom properties
* Fix code style
* Optimize custom property checking
* Prevents adding units to css custom properties in markup creation
* Update passing tests
* Fix argument name and reuse check in DEV
* Remove internal forwarding modules for /lib/
* Add *Entry suffix to all entry points
* Don't bundle ReactNativeFeatureFlags since it's shimmed
* Delete TestRendererStack
* Switch tests at forwarding modules rather than via Jest
* Share mocks between regular and equivalence fixtures
* Rename environment flag to be more generic
* Remove accidental variable name change
* Minor naming changes for consistency
Files that have two versions get the engine in variable name.
* Add ReactNoop.yield, ReactNoop.flushAndYield, ReactNoop.flushUnitsOfWork
Incremental tests often rely on yielding at a specific point. Using an
explicit API should make our tests more resilient to changes
in implementation.
* Fuzz tester that simulates Sierpinski Triangle demo
The tests only assert that the output of the tree is consistent after
each action, and that the final result after all work has flushed is
the expected value. It does not assert how work is reused, which means
it can't detect starvation issues. However, this also means that it
is fairly resilient to changes in our incremental algorithm.
