I'm not sure this should happen either - but it solves a problem for a few users.
Also pinging @caitp @littledan about the promise hooks so they can take a look.

Not entirely convinced on this either but the change generally looks ok.

report to whom? If this would be considered a Node.js core bug, then the error message should be more descriptive.

This is copied verbatim from MakeCallback ¯\_(ツ)_/¯ I’ve updated this to be a bit more descriptive anyway.

I thought it looked familiar :-) We should likely fix it over there also :-)

Probably, but I’m not eager to touch that code until #11883 lands. After that I’d be up for all kinds of refactoring… aside, I don’t think there has been a bug report for this crash site in forever, so it probably doesn’t really matter. :)

Minor nit, feel free to ignore but the indenting on this line is odd to me

It’s odd to me too, I’ll gladly take suggestions. (Maybe just splitting the statement into multiple ones is the best way…)

if you restructure this to return early, then indentation becomes better.

Again, this is very much in line with what MakeCallback does/uses, and it makes it clear that this actually messes with the Promise
object itself (I would want that to be visible). But if anybody feels strongly I can change this as well. ¯\_(ツ)_/¯

I think in this case, exposing the domain
would be the right thing to do for sake of consistency

Again, I don't have much context, but in_domain() check seems important, are you sure you don't need to do it for the other cases?

I’m pretty sure, yes. This is based on existing code for similar circumstances (plain JS calls coming from the void), and in_domain()
will automatically be true between the enter and exit callbacks.

Don't have much context about domains but, AFAICS, the promise nor the parent is passed to the domain callback. Is that ok?

The domain enter/exit callbacks don’t do much, they basically just push or pop an object to an array.
I didn't see the need for this when designing the API. Please file a V8 bug with a use case. I can take a look. |
It would be good to coordinate this work with the async hooks work here: #11883. Node can only register one set of promise hook callbacks (by design) so the callbacks will have to handle emitting the right async hooks lifecycle events in addition to propagating domains (if desired). I have been prototyping promise hook integration for async hooks on top of #11883. I have experimented with refactoring |

Well, it forces consumers to use global state, or
@matthewloring Sounds good, I’d be curious to see what you have come up with. |
There's only one possible promisehook that can be used so global state isn't the worst, but the embedder is free to create better encapsulation if required. Also, you can get the isolate from the promise object directly, no need for Isolate::GetCurrent(). Anyways, this is better discussed in a V8 bug. |

I think it should be safe (and a little more efficient) to call Environment::GetCurrent(promise->CreationContext())
.
(It must be safe because some of the operations in this function will error without a HandleScope. I think the promise hook implicitly runs inside one.)

It would be good to check that domains + promises + vm.runInNewContext() also does the right thing.
FWIW, I'm generally in favor of this change. Some (including myself!) have built continuation-local-storage-on-the-cheap on top of domains, & end up having to strictly enforce domain-compliant promise library use. This gives us a good road forward to move onto native promises, and from there onto asynchooks. |
@bnoordhuis I should have addressed your comments |
Not sure I follow. Can you point to the exact step in the spec?
The only real use of the resolve hook is to provide information about who is triggering the promise resolving functions (to stitch together better stack traces).
with the resolve hook, you can figure out that |
@gsathya My intuition would be that That should give the same stack traces etc., but carrying the additional information of the actual new Promise state. |

Hey all, I am wondering if anyone on this thread can help answer this question regarding Promises + Domains, thanks |
Not entirely convinced this should happen, but @misterdjules brought it up and I thought one might as well give it a try. ¯\_(ツ)_/¯ Take a look, and let me know what you think.
Aside: It seems like a V8 design bug that
Isolate::SetPromiseHook()
/PromiseHook()
don’t take avoid* data
opaque, does anybody agree? I’d probably like to change that in V8 then. (Also, same question forIsolate::SetPromiseRejectCallback()
… am I missing something? This can’t be intentional, right?)/cc @nodejs/diagnostics and fyi @ORESoftware
