Add StreamMessage.of(future) that produces StreamMessage from the future #4995
Conversation
Motivation: We have `HttpResponse.from(future)` that produces the `HttpResponse` when the future completes. It woulb be nice if we can have similar one for `HttpRequest` which produces the data and trailers when the future compeltes. Modifications: - Add `DeferredHttpRequest` which is created from `HttpRequest.from(future)`. Result: - You can now create an `HttpRequest` that produces data and trailers after a future completes.

Is this change intentional?

We should revert this before merging.

Question) Is this API needed since CompletionFuture inherits CompletionStage?

Question) would it rather make more sense to name this method of, and create the counterparts in HttpResponse? (and deprecate from() factory methods)

Changed to of. 😉
For HttpResponse, I actually left TODO for it because it needs to change quite a lot.
Let me send another PR for that. 😉

I think optionally we could also apply the CF completion check here too (I find it odd that only some APIs do this optimization, while others don't)

If so, we cannot use the executor specified. 😉 Let me add a comment there.

What do you think of adding of(CompletableFuture<StreamMesage<T>> future, EventExecutor) for consistency, otherwise, removing of(CompletableFuture<StreamMesage<T>> future) from public API?

removing of(CompletableFuture<StreamMesage> future) from public API?
+1 for this. I will also deprecate/remove HttpResponse.from(CompletableFuture<? extends HttpResponse> future). 😉

@ikhoon Forgot to address the comments. 😓 All addressed. PTAL. 😉 |

Thanks for reviewing. 😉 |
Motivation: We have decided to deprecate `HttpResponse.from(...)` methods and use `HttpResponse.of(...)` instead for consistency. line#4995 (comment) Modification: - Deprecate `HttpResponse.from(CompletionStage)` and its variants. - `HttpResponse.of(CompletionStage)` and its variants are added. Result: - `HttpResponse.from(CompletionStage)` and its variants methods are deprecated. - Use `HttpResponse.of(CompletionStage)` and its variants instead.

Motivation:
We have
HttpResponse.from(future)that produces theHttpResponsewhen the future completes. It would be nice if we can have it onStreamMessagelevel.Modifications:
StreamMessage.of(future)that produces another StreamMessage from the futureResult:
StreamMessageusing a future.
