* Fiber: warn for refs on SFCs
* Stateless refs: update warning to use component stack
* Warn for function refs (stack and fiber)
* Add owner reference to ref warnings
* Centralize stack ref warnings in ReactRef.attachRef
* Fiber stateless comp ref warning should only do work when necessary
* ReactDebugCurrentFiber maybe FunctionalComponents should act this way instead
* (chore) scripts/fiber/record-tests
* Add component._compositeType to ReactInstance Flow definition
* Don't handle 'stack inside fiber' case in the warning
We don't have a test for it. It's easy to mess it up and print the wrong thing so instead of verifying it I'll just remove this bit.
* Revert the change to getCurrentFiberOwnerName
This happened to work, but it is just a coincidence. This change didn’t really match what the function was supposed to be doing.
I’m not sure what the correct fix would be yet so this commit breaks tests.
* Add component indirection to the tests using owner name
This passes in Stack. It helps ensure we supply the correct owner name.
* Invalid type invariant should read owner from element
This brings the Fiber behavior in line with how Stack does it. The Fiber test was passing accidentally but broke down in more complicated cases (such as when we have an <Indirection> between the owner and the failing element).
Now we can also remove the weird cases from getCurrentFiberOwnerName() that didn't really make sense but helped get the (incomplete) tests pass in the past.
* Fiber should throw on a string ref inside functional component
* Add manual build fixtures
* Inject ReactDOM into ReactWithAddons from ReactWithAddons
We used to read ReactDOM as a global inside ReactAddonsDOMDependenciesUMDShim.
This didn't work in AMD environments such as RequireJS and SystemJS.
Instead, I changed it so that ReactDOM gets injected into ReactWithAddons by ReactDOM itself.
This way we don't have to try to require it (which wouldn't work because AMD doesn't handle circular dependencies well).
This means you have to load ReactDOM first before using ReactDOM-dependent addons, but this was already the case before.
This commit makes all build fixtures pass.
* Memoize ReactDOM to avoid going into require on every access
* Add Brunch fixture
* Inline requires to work around Brunch bug
See #8556 and https://github.com/brunch/brunch/issues/1591#issuecomment-270742503 for context.
This appears to be a Brunch bug but we can keep a temporary fix until the next major.
* (WIP) Nesting warnings
* Remove indirection
* Add a note about namespace
* Fix Flow and make host context required
This makes it easier to avoid accidental nulls.
I also added a test for the production case to avoid regressing because of __DEV__ branches.
When resetting the priority in the complete phase, check the priority of
the update queue so that updates aren't dropped.
Updates inside render, child cWRP, etc are no longer dropped.
The next step is sort the queue by priority and only flush updates that
match the current priority level.
* Implement component stack for some warnings in Fiber
* Keep Fiber debug source up to date
When an element changes, we should copy the source and owner again.
Otherwise they can get stale since we're not reading them from the element.
* Remove outdated TODOs from tests
* Explicitly specify Fiber types to include in the stack
Fixes an accidental omission when both source and owner are null but displayName exists.
* Fix mised Stack+Fiber test to not expect extra warnings
When we're in Fiber mode we don't actually expect that warning being printed.
* Warn on passing different props to super()
* Implement duplicate key warnings
We keep known keys in a set in development. There is an annoying special case where we know we'll check it again because we break out of the loop early.
One test in the tree hook regresses to the failing state because it checks that the tree hook works without a Set available, but we started using Set in this code. It is not essential and we can clean this up later when we decide how to deal with polyfills.
* Move ReactTypeOfWork to src/shared
It needs to be available both to Fiber and Isomorphic because the tree hook lives in Isomorphic but pretty-prints Fiber stack.
* Add dev-only ReactDebugCurrentFiber for warnings
The goal is to use ReactCurrentOwner less and rely on ReactDebugCurrentFiber for warning owner name and stack.
* Make Stack invariant messages more consistent
Fiber used a helper so two tests had the same phrasing.
Stack also used a helper for most invariants but hardcoded a different phrase in one place.
I changed that invariant message to use a helper which made it consistent with what it prints in Fiber.
* Make CSSPropertyOperations use getCurrentFiberOwnerName()
This gets mount-time CSS warnings to be printed.
However update-time warnings are currently ignored because current fiber is not yet available during the commit phase.
We also regress on HostOperation hook tests but this doesn't matter because it's only used by ReactPerf and it doesn't work with Fiber yet anyway. We'll have to think more about it later.
* Set ReactDebugCurrentFiber during the commit phase
This makes it available during updates, fixing the last failing test in CSSPropertyOperations.
* Add DOM warnings by calling hooks directly
It is not clear if the old hook system is worth it in its generic incarnation. For now I am just hooking it up to the DOMFiber renderer directly.
* Add client-side counterparts for some warning tests
This helps us track which warnings are really failing in Fiber, and which ones depend on SSR.
* Add iterable cases to MultiChildReconcile test
Stack currently supports rendering iterables, but Fiber does not.
Previously we didn't have any public API tests for iterables. We have tests for traverseAllChildren() which is shared between React.Children and Stack. However Fiber doesn't currently use it, and likely won't. So this commit is a first step towards actually testing iterable support via public API. The next step will be to port traverseAllChildren() tests to test React.Children API instead.
* Implement iterable reconciliation in Fiber
This uses the same exact algorithm as array reconciliation but uses iterator to step through.
This gets reconcile tests to pass again but introduces a regression in ReactMultiChildText case which uses Maps as children. It passed before because Maps were ignored, but now it's failing because this actually runs the Map code path in Fiber. We can throw early in this case when we want to follow up on this.
* Rewrite traverseAllChildren() tests against React.Children API
This function was used in React.Children and Stack.
The corresponding reconciliation functionality is being tested by ReactMultiChild tests.
So we can move these tests to ReactChildren and test its public API.
We need this to safely extract the current event listeners from the props.
Unfortunately, we are still not safe to use the return pointer since it
may not point to the current tree when the Fiber is reused. So this is not
fully done yet.
* Use the public ReactDOMServer in tests
We need this because it runs the injection.
* Let Fiber skip react data attributes and comments in SSR tests
This markup is testing implementation details rather than behavior.
I'll plan to change all of our console.error and component-tree expects to expectDev. It's a little annoying that we need to make sure tests don't throw (see my change to normalizeCodeLocInfo) but any alternative would seem to require two separate test runs or a much more cumbersome syntax.
