04/10/2023, 7:23 PM> im not sure i follow, pass resolve to which thread? The thread which is gonna do the request and eventually send `resolve`/`reject`+the response back to the main thread. - you mean just: ```haxe sys.thread.Thread.createWithEventLoop(() -> { makeRequestCommon(request).then(response -> { resolve(...); }, error -> { ... }); }); ```b

bright-gpu-74537
04/10/2023, 7:25 PMpretty sure i had something similar before - I mean something like this: ```hx enum WorkerResult { Success(resp:HttpResponse, resolve:HttpResponse->Void); Error(e:Any, err:Any->Void; } var deque = new sys.thread.Deque<WorkerResult>(); function makeThreadedRequest(request:HttpRequest):Promise<HttpResponse> { return new Promise((resolve, reject) -> { sys.thread.Thread.createWithEventLoop(() -> { makeRequestCommon(request).then(response -> { deque.push(Success(response, resolve)); }, error -> { deque.push(Error(error, reject)); }); }); }); } function onTimer() { var ready = []; while(true) { var o = deque.pop(false); if(o != null) ready.push(o) else break; } for (item in ready) { switch item { case Success(resp, resolve): resolve(resp); case Error(e, reject): reject(e); } } } ```p

bright-gpu-74537
04/10/2023, 7:28 PMgotcha... yeah, cleaner for sure - If you have proper event loop integration you can even avoid the timer and deque and do ```hx function makeThreadedRequest(request:HttpRequest):Promise<HttpResponse> { return new Promise((resolve, reject) -> { var mainThread = Thread.current(); mainThread.events.promise(); sys.thread.Thread.createWithEventLoop(() -> { makeRequestCommon(request).then(response -> { mainThread.events.runPromised(() -> resolve(response)); }, error -> { mainThread.events.runPromised(() -> reject(error)); }); }); }); } ```p

04/10/2023, 7:34 PMyeah, i was actually looking to the remove the timer tbh, and figured the event loop impl was the way to go... just need to work out how thats gonna work in things like wx and raylib and make sure its not going to introduce some type of general perf penalty (i cant see why it would) - There will be a perf penalty if a lot of threads are trying to run events on the main thread's event loop at the same time, since you'll get lock contention. But in normal situations the overhead should be minimal.p

But in normal situations the overhead should be minimal. - also, in this case it isnt alot of threads trying to do "something", its one callback checking the result of X threads, so im guessing it will be fine... if the callback is taking ages (for whatever reason) then that will hold everything up, but thats not different to the timer approachb
