* Verify that functional component ref warning is deduplicated
It's not a big problem for string refs because the ref stays the same and the warning code path runs once per mount.
However, it is super annoying for functional refs since they're often written as arrows, and thus the warning fires for every render.
Both tests are currently failing since we're mounting twice, so even the string ref case prints warnings twice.
* Extract the warning condition to the top level
We don't want to run getStackAddendumByID() unless we actually know we're going to print the warning.
This doesn't affect correctness. Just a performance fix.
* Deduplicate warnings about refs on functional components
This fixes the duplicate warnings and adds an additional test for corner cases.
Our goal is to print one warning per one offending call site, when possible.
We try to use the element source for deduplication first because it gives us the exact JSX call site location.
If the element source is not available, we try to use the owner name for deduplication.
If even owner name is unavailable, we try to use the functional component unique identifier for deduplication so that at least the warning is seen once per mounted component.
* 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
Only store cached masked/unmasked contexts on context consumers. Move all references to __reactInternal* cached attributes inside of ReactFiberContext.
* Show Source Error Addemden if __source available
* Add Parent Stack on invalid element type
* refactor to use normalizeCodeLocInfo
* Remove ( ) from addendum
This moves the current fixture architecture to one based around create-react-app. There are a few important things to note:
* The react-loader.js script is always loaded before the bundle and will populate React and ReactDOM on the window. It is then read from the window by all components.
* The UI for the "React Sandbox" or "React Fixtures App" is also rendered with whatever version of React the user has selected. This means we dont have to deal with iframes or worry about multiple versions of React potentially interferring. But it also means that all components must be written using createClass to be fully backwards compatable. I tested back to 0.13.1 and it works fine.
