[JSC] Cooperative driving of async generators
https://bugs.webkit.org/show_bug.cgi?id=319133
rdar://181951971
Reviewed by Yijia Huang.
This is our next step in the long journey towards native microtasks and
efficient async implementation. This patch introduces cooperative
driving mechanism of async generators. Let's say we have a code below.
async function* gen () {
yield 42;
yield 42;
yield 42;
}
async function main() {
for await (let value of gen()) {
...
}
}
In the above script, we have a great syntax-guaranteed things,
1. for-await-of completely hides `next()` invocation. This means that
the result of `next()` call is not escaped anywhere user observable space.
In this case, async generator's promise from next().
2. for-await-of is awaiting for each promise result from `next()` call
of async generator. And this `await` is directly invoking
PerformPromiseThen, skipping `Promise.prototype.then` calls, so user
cannot insert an observable function by overriding
`Promise.prototype.then` when it is a native promise.
3. When usual %AsyncGeneratorPrototype%.next function is invoked, if it is
normal
async generator, it is guaranteed to produce a native promise.
The above 3 characteristics means that we can skip promise creation if
an async function is cooperatively driving async generator via for-await-of.
1. for-await-of is used in the async function. If gen()'s result is genuine
async generator and `next` function is %AsyncGeneratorPrototype%.next,
then the promise is not observable. Then, we do not create a promise / return
a promise! Instead, we return a sentinel (instead of promise) that is "we
will
be driven by the fast-suspension mechanism". Then instead of enqueuing a
newly created promise, we enqueue this async function's generator (driver)
into the async generator's queue.
2. Then async generator will execute `yield` etc., and resolve the
queued promise. Previously, there was a promise here. But instead, we
now have a async function's generator. So we drive it with a special
InternalMicrotask::AsyncGeneratorFastConsumerResume.
3. InternalMicrotask::AsyncGeneratorFastConsumerResume will be driven
with async function generator. And we resume async function generator
instead.
The execution is completely aligned to the normal promise-based driving
in terms of ticks. But it is driven significantly more efficiently: we
do not create a promise and schedule a resolution through a promise. We
capture the driver (async function generator) directly and it
cooperatively registers itself to the driven async generator. And async
generator cooperatively resolves this driver when it gets the resolution!
As a result, we no longer directly call JS %AsyncGeneratorPrototype%.next().
So we move it to C++ too.
