Fixes #18944
|

(#21074)
This PR uses the new `cancel` method of `TransformStream` to properly
clean up the internal `TextDecoder` used in `TextDecoderStream` if the
stream is cancelled.
Fixes #13142

We can move all promise ID knowledge to deno_core, allowing us to better
experiment with promise implementation in deno_core.
`{un,}refOpPromise(promise)` is equivalent to
`{un,}refOp(promise[promiseIdSymbol])`
|
|
Use our safer typed externals for the external required for resource
streams.

This PR introduces several optimizations to streams
### Highlights:
- `ReadableStream` constructor: +20% iter/s.
- `WritableStream` constructor: +50% iter/s.
- `TransformStream` constructor: +30% iter/s.
- `ReadableStream` iterator (both 2 and 20 chunks): +42% and +25%
iter/s.
- `ReadableByteStream` iterator (both 2 and 20 chunks): +39% and +20%
iter/s.

resourceForReadableStream (#20622)

ReadableStream (#20570)

channel that is byte-size backpressure-aware.
Using the testcase in the linked bug, we see all the small writes

Optimise Buffer's string operations, most significantly when dealing
with ASCII and UTF-16. Base64 and HEX encodings are affected to much
lesser degrees.
## Performance
### String length 15
With very small strings we're at break-even or sometimes even lose a tad
bit of performance from creating a `DataView` that ends up not paying
for itself.

performance is enormous.

(#20303) (#20370)
This reverts commit
https://github.com/denoland/deno/commit/83426be6eead06c680ae527468aeaf8723543ff2.
Includes a regression test.
|
|
Rewrites 3 ops that used "op(deferred)" to use "op2(async(lazy))"
instead.
This will allow us to remove codepath for handling "deferred" ops in
"deno_core".

Extracted from fast streams work.
This is a resource wrapper for `ReadableStream`, allowing us to treat
all `ReadableStream` instances as resources, and remove special paths in
both `fetch` and `serve`.
Performance with a ReadableStream response yields ~18% improvement:
```
return new Response(new ReadableStream({
start(controller) {
controller.enqueue(new Uint8Array([104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]));
controller.close();
}
})
```

This PR optimizes `Event` constructor
- ~Added a fast path for empty `eventInitDict`~ Removed `EventInit`
dictionary converter
- Don't make `isTrusted` a
[LegacyUnforgeable](https://webidl.spec.whatwg.org/#LegacyUnforgeable)
property. Doing so makes it non-spec compliant but calling
`Object/Reflect.defineProperty` on the constructor is a big bottleneck.
Node did the same a few months ago
https://github.com/nodejs/node/pull/46974. In my opinion, the
performance gains are worth deviating from the spec for a
browser-related property.

Fixes https://github.com/denoland/deno/issues/19866
|
|
This PR ensures that the original signal event is fired before any
dependent signal events.
---
The enabled tests fail on `main`:
```
assert_array_equals: Abort events fired in correct order expected property 0 to be
"original-aborted" but got "clone-aborted" (expected array ["original-aborted", "clone-aborted"]
got ["clone-aborted", "original-aborted"])
```

This PR fixes some crashing WPT tests due to an unresolved promise.
---
This could be a [stream spec](https://streams.spec.whatwg.org) bug
When `controller.close` is called on a byob stream, there's no cleanup
of pending `readIntoRequests`. The only cleanup of pending
`readIntoRequests` happen when `.byobRequest.respond(0)` is called, it
happens
here:https://github.com/denoland/deno/blob/6ba245fe2570b29e35a4fd296a196a58870b1e3c/ext/web/06_streams.js#L2026
which ends up calling `readIntoRequest.closeSteps(chunk);` in
https://github.com/denoland/deno/blob/6ba245fe2570b29e35a4fd296a196a58870b1e3c/ext/web/06_streams.js#L2070
To reproduce:
```js
async function byobRead() {
const input = [new Uint8Array([8, 241, 48, 123, 151])];
const stream = new ReadableStream({
type: "bytes",
async pull(controller) {
if(input.length === 0) {
controller.close();
// controller.byobRequest.respond(0); // uncomment for fix
return
}
controller.enqueue(input.shift())
},
});
const reader = stream.getReader({ mode: 'byob' });
const r1 = await reader.read(new Uint8Array(64));
console.log(r1);
const r2 = await reader.read(new Uint8Array(64));
console.log(r2);
}
await byobRead();
```
Running the script triggers:
```
error: Top-level await promise never resolved
```
