Support preinit as script
Support resources from async scripts
Support saving the precedence place when rendering the shell
There was a significant change to the flushing order of resources which follows the general principal of...
1. stuff that blocks display
2. stuff that we know will be used
3. stuff that was explicitly preloaded
As a consequence if you preinit a style now it won't automatically flush in the shell unless you actually depend on it in your tree. To avoid races with precedence order we now emit a tag that saves the place amongst the precedence hierarchy so late insertions still end up where they were intended
There is also a novel hydration pathway for certain tags. If you render an async script with an onLoad or onError it will always treat it like an insertion rather than a hydration.
* restore preinit style flushing behavior and nits
* Print built-in specific error message for toJSON
This is a better message for Date.
Also, format the message to highlight the affected prop.
* Describe error messages using JSX elements in DEV
We don't have access to the grand parent objects on the stack so we stash
them on weakmaps so we can access them while printing error messages.
Might be a bit slow.
* Capitalize Server/Client Component
* Special case errror messages for children of host components
These are likely meant to be text content if they're not a supported object.
* Update error messages
The download-build script works by scraping the CircleCI job number from
the GitHub status API. Yes, I know this is super hacky but last I
checked this was the least bad of not a lot of options. Because the
response is paginated, sometimes the status for the build job exceeds
the page size.
This increases the page size to 100 so this is less likely to happen.
It'd be great to find a better way to download the artifacts. I don't
love how brittle this solution is. I think switching to the GitHub
Checks API might be worth trying, but last I looked into it, it has
other flaws.
* Scaffolding for react-dom/unstable_external-server-runtime
Implements a new bundle type for in our build config called
BROWSER_SCRIPT. This is intended for scripts that get delivered straight
to the browser without needing to be processed by a bundler. (And also
doesn't include any extra UMD crap.)
Right now there's only a single use case so I didn't stress about making
it general purpose.
The use case is: a script that loads the Fizz browser runtime, and sets
up a MutationObserver to receive instructions as HTML streams in. This
will be an alternative option to the default Fizz behavior of sending
the runtime down as inline script tags, to accommodate environments
where inline script tags are not allowed.
There's no development version of this bundle because it doesn't contain
any warnings or run any user code.
None of the actual implementation is in this PR; it just sets up the
build infra.

* Set BUNDLE_SCRIPT's GCC output format to ES5
This removes the automatic 'use strict' directive, which we don't need.

* Move Fizz inline instructions to unified module
Instead of a separate module per instruction, this exports all of them
from a unified module.
In the next step, I'll add a script to generate this new module.
* Add script to generate inline Fizz runtime
This adds a script to generate the inline Fizz runtime. Previously, the
runtime source was in an inline comment, and a compiled version of the
instructions were hardcoded as strings into the Fizz implementation,
where they are injected into the HTML stream.
I've moved the source for the instructions to a regular JavaScript
module. A script compiles the instructions with Closure, then generates
another module that exports the compiled instructions as strings.
Then the Fizz runtime imports the instructions from the
generated module.
To build the instructions, run:
yarn generate-inline-fizz-runtime
In the next step, I'll add a CI check to verify that the generated files
are up to date.
* Check in CI if generated Fizz runtime is in sync
The generated Fizz runtime is checked into source. In CI, we'll ensure
it stays in sync by running the script and confirming nothing changed.
* Missing Hooks
* Remove www forks. These can use __SECRET... instead.
* Move cache to separate dispatcher
These will be available in more contexts than just render.
Publish an aliasable entry for `react-dom` top level package exports for use in server environments. This is a stub containing only the exports that we expect to retain in the top level once 19 is released
* track resources in different roots separately
* flow types
* add test demonstrating portals deep into shadowRoots
* revert hostcontext changes
* lints
* funge style cache key a la ReactDOMComponentTree
* hide hacks in componentTree
* Update safe-string-coercion to handle additions of string literals
Adding strings shouldn't trigger a lint violation of this rule, since
adding strings are always safe.
- method unbinding is no longer supported in Flow for soundness, this added a bunch of suppressions
- Flow now prevents objects to be supertypes of interfaces/classes

This upgrade made more expressions invalidate refinements. In some
places this lead to a large number of suppressions that I automatically
suppressed and should be followed up on when the code is touched.
I think most of them might require either manual annotations or moving
a value into a const to allow refinement.

This was a large upgrade that removed "classic mode" and made "types first" the only option.
Most of the needed changes have been done in previous PRs, this just fixes up the last few instances.

This contains one code change, renaming the local function `ChildReconciler` to `createChildReconciler` as it's called as a function, not a constructor and to free up the name for the return value.
* [Fizz/Float] Float for stylesheet resources
This commit implements Float in Fizz and on the Client. The initial set of supported APIs is roughly
1. Convert certain stylesheets into style Resources when opting in with precedence prop
2. Emit preloads for stylesheets and explicit preload tags
3. Dedupe all Resources by href
4. Implement ReactDOM.preload() to allow for imperative preloading
5. Implement ReactDOM.preinit() to allow for imperative preinitialization
Currently supports
1. style Resources (link rel "stylesheet")
2. font Resources (preload as "font")
later updates will include support for scripts and modules
This was added back in #17880 to make CI pass for an unrelated change.
This limits the max worker setting to CI environments as removing the setting completely still seems to break on CircleCI.
This lets us share it with react-server-dom-webpack while still having a
dependency on react-dom. It also makes somewhat sense from a bundling
perspective since react-dom is an external to itself.
Similar to Fizz, Flight now supports a return value from the user provided onError option. If a value is returned from onError it will be serialized and provided to the client.
The digest is stashed on the constructed Error on the client as .digest
Enables well formed exports for /scheduler. Some of the modules there were missing `@flow` and were therefore completely unchecked (despite some spurious types sprinkled around).
* [Flight] Align Chunks with Thenable used with experimental_use
Use the field names used by the Thenable data structure passed to use().
These are considered public in this model.
This adds another field since we use a separate field name for "reason".
* Implement Thenable Protocol on Chunks
This doesn't just ping but resolves/rejects with the value.
* Subclass Promises
* Pass key through JSON parsing
* Wait for preloadModules before resolving module chunks
* Initialize lazy resolved values before reading the result
* Block a model from initializing if its direct dependencies are pending
If a module is blocked, then we can't complete initializing a model.
However, we can still let it parse, and then fill in the missing pieces
later.
We need to block it from resolving until all dependencies have filled in
which we can do with a ref count.
* Treat blocked modules or models as a special status
We currently loop over all chunks at the end to error them if they're
still pending. We shouldn't do this if they're pending because they're
blocked on an external resource like a module because the module might not
resolve before the Flight connection closes and that's not an error.
In an alternative solution I had a set that tracked pending chunks and
removed one at a time. While the loop at the end is faster it's more
work as we go.
I figured the extra status might also help debugging.
For modules we can probably assume no forward references, and the first
async module we can just use the promise as the chunk.
So we could probably get away with this only on models that are blocked by
modules.
This update range includes:
- `types_first` ([blog](https://flow.org/en/docs/lang/types-first/), all exports need annotated types) is default. I disabled this for now to make that change incremental.
- Generics that escape the scope they are defined in are an error. I fixed some with explicit type annotations and some are suppressed that I didn't easily figure out.
