[Merged by Bors] - Execution stack & promises #2107

Razican · 2022-06-08T21:05:29Z

This PR overrides #1923. It also removes the queues dependency added there, and rebases it to the latest main branch state.

It adds the following:

A job queue (in Context)
The constructor Promise
Promise.race
Promise.reject
Promise.resolve
get Promise [ @@species ]
Promise.prototype [ @@toStringTag ]
Promise.prototype.then
Promise.prototype.finally
Promise.prototype.catch
The additional needed infrastructure
A test case showcasing the run-to-completion semantics.

An example program that shows the control flow with this addition is:

new Promise((res, rej) => {
  console.log("A");
  res(undefined);
}).then((_) => console.log("B"));
console.log("C");

Which would output:

A
C
B

Note: it still requires bringing the enhancements proposed by multiple members of the team.

Feel free to check this up and merge it. I will create separate PRs for async/await execution and the [[Done]] field in iterables, based on this one.

I got some inital comments. I will probably take a detailed look later today.

boa_engine/src/job.rs

I think there are some more optimizations with some types, but let's go ahead and merge it and address those in follow ups. From here we got a really nice starting point into everything async.

This PR overrides #1923. It also removes the `queues` dependency added there, and rebases it to the latest `main` branch state. It adds the following: - A job queue (in `Context`) - The constructor [`Promise`](https://tc39.es/ecma262/#sec-promise-executor) - [`Promise.race`](https://tc39.es/ecma262/#sec-promise.race) - [`Promise.reject`](https://tc39.es/ecma262/#sec-promise.reject) - [`Promise.resolve`](https://tc39.es/ecma262/#sec-promise.resolve) - [`get Promise [ @@species ]`](https://tc39.es/ecma262/#sec-get-promise-@@species) - [`Promise.prototype [ @@toStringTag ]`](https://tc39.es/ecma262/#sec-promise.prototype-@@tostringtag) - [`Promise.prototype.then`](https://tc39.es/ecma262/#sec-promise.prototype.then) - [`Promise.prototype.finally`](https://tc39.es/ecma262/#sec-promise.prototype.finally) - [`Promise.prototype.catch`](https://tc39.es/ecma262/#sec-promise.prototype.catch) - The additional needed infrastructure - [`PerformPromiseThen ( promise, onFulfilled, onRejected [ , resultCapability ] )`](https://tc39.es/ecma262/#sec-performpromisethen) - [`TriggerPromiseReactions ( reactions, argument )`](https://tc39.es/ecma262/#sec-triggerpromisereactions) - [`PerformPromiseRace ( iteratorRecord, constructor, resultCapability, promiseResolve )`](https://tc39.es/ecma262/#sec-performpromiserace) - [`RejectPromise ( promise, reason )`](https://tc39.es/ecma262/#sec-rejectpromise) - [`FulfillPromise ( promise, value )`](https://tc39.es/ecma262/#sec-fulfillpromise) - [`IfAbruptRejectPromise ( value, capability )`](https://tc39.es/ecma262/#sec-ifabruptrejectpromise) - [`CreateResolvingFunctions ( promise )`](https://tc39.es/ecma262/#sec-createresolvingfunctions) - [`NewPromiseCapability ( C )`](https://tc39.es/ecma262/#sec-newpromisecapability) - [`NewPromiseReactionJob ( reaction, argument )`](https://tc39.es/ecma262/#sec-newpromisereactionjob) - [`NewPromiseResolveThenableJob ( promiseToResolve, thenable, then )`](https://tc39.es/ecma262/#sec-newpromiseresolvethenablejob) - [`PromiseResolve ( C, x )`](https://tc39.es/ecma262/#sec-promise-resolve) - A test case showcasing the run-to-completion semantics. An example program that shows the control flow with this addition is: ```javascript new Promise((res, rej) => { console.log("A"); res(undefined); }).then((_) => console.log("B")); console.log("C"); ``` Which would output: ``` A C B ```
