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.
* Handles risky callbacks on setState. Fixes#8238
* Updates try-catch to cover `callback` when context is not present.
* Updates code to trapErrors instead of swallowing them.
* Fixes flow errors
* Incorporates review comments
* Traps only the first error.
Removes `callbackWasCalled` and updates fiber tests.
I came up with a contrived case of where nested controlled events could
fire within the same batch - but on different targets.
I think we came to the conclusion that controlled values typically cannot
use preventDefault so it is ok that they don't flush until after the event
has finished. So therefore we accumulate a queue of all the nested targets
within a batch and then restore state on all of them.
I'm still skeptical that this is the correct way to do controlled values.
The reason we have to do them in a single event loop is because when you
type, the sequence of values that get accepted or not can matter. I wonder
if there is a scenario we can come up with where you can fire multiple
inner events in an event loop and end up with batching causing problems.
This effectively just reimplements asap again but with no allocations for
a single target and no closure allocations.
* Make the Shallow Rendering example clearer
I was reading through the documentation, and I found that the `render` call on the `renderer` was missing.
* Use a regular function to define MyComponent
* Use _hostContainerInfo to track test renderer options
The transaction is not available when unmounting or updating the
instance, so we track it using _hostContainerInfo
* Throw if hostContainerInfo is not populated in getPublicInstance
* Linting fixes
* Remove transaction from ref lifecycle code path
We don't need to pass the transaction around anymore since we store the
test options on _hostContainerInfo instead
* Remove unused argument
If a controlled target fires within another controlled event, we should not
restore it until we've fully completed the event. Otherwise, if someone
reads from it afterwards, they'll get the restored value.
Not super happy with this particular solution.
* took codes.json from the 15-dev branch
* fixed react:extract-errors task in gulpfile
* generated error codes
* Revert "generated error codes"
This reverts commit b8f3aeed9d8f0d469edd5f6623fa6090930594d8.
* Added a README for the error code system
This reverts commit a878c3056d.
The previous stuff that this builds on didn't successfully land fully. Since I
want to measure this in isolation, I'll revert this for now.
This just reads events from the props instead of storing them in a
listener back.
I had to rewrite a bunch of tests to cover this model.
I removed the tests that just test the adding and removing over listeners
since there is no equivalent behavior anymore.
This reverts the implementation in 33325ad009.
I didn't mean to merge the implementation since it is incorrect and incomplete.
I meant to just merge the unit test.
* Ensure that we're listening to all onChange dependencies for controlled inputs
When there is no onChange event handler, we should still listen to it to
ensure controlled values get reset.
There is warning associated with this but the prod behavior should still be
respected.
* Rerun tests
When there is no onChange event handler, we should still listen to it to
ensure controlled values get reset.
There is warning associated with this but the prod behavior should still be
respected.
* Use explicit pass for restoring controlled state instead of asap
This gets rid of the first class ReactUpdates.asap scheduling. Instead of
scheduling a first class function to invoke later, I introduce an explicit
phase for restoring controlled state after dispatching events.
We assume that the deepest event target is the thing that needs its state
restored.
* Drop special cases for onChange in wrappers
We're now not using anything special about onChange handling in the
wrappers. Yay!
* Attempt to fix ReactDOMTextComponent test in Fiber
Obviously, some tests pass but the reconciliation is still incomplete on this in Fiber.
Those changes just ignore reconciliation Comments while asserting (this fixes 2 tests already) but now shows that Fiber lacks some reconciliation features.
* Transmit a parentInstance to commitTextUpdate
This is done in case a Node#normalize() was performed on the parent instance and that the TextInstance got desolidarized from the parent. We provide the parent known by the parent Fiber to reattach the DOM node in this case.
* Added a more complex case around split nodes
This test does not assume one split node substitution alone but also some non-split nodes.
* Fiber supports split text nodes
This is done by suppressing nodes appearing during the split. this is based by comparing against the old value known by the Fiber.
* Simplify siblings cleaning in commitTextUpdate
No need to assert instanceof Text since the length comparator will work correctly.
* Ensure non-text nodes won't be removed
* Fix flow for Fiber Text reconciliation additions
Mostly define types as optionals. Respects the strict DOM API around Node & Element.
* Append at any stack stage only if necessary
The direct parent of the TextNode fiber may not contain the host node. We have to go through the hierarchy. However, since this work may be expensive, we only do it if absolutely necessary!
* Use tag & ReactTypeOfWork to find an HostComponent
* Addfailing scenario when running Node.normalize()
It happens when non-text-elements are added in the mix. @sebmarkbage seems to have an idea on how to fix it. This is just a repro of the bug!
* Register failing/passing fiber tests
This gets rid of the global flag on if something has listened to onSelect
and instead reads the isListening map if all the events are covered.
This is required if we want to attach events locally at roots.
Could be slower perf wise to handle events. An alternative solution would
be to attach a special flag on the listener map for the document so we
don't have to check the full dependency list.
However, my favorite solution would be to just eagerly attach all event
listeners (except maybe wheel). Then we don't have to do any of this stuff
on a per element basis.
