Set RequestContext.isTimedOut(true) on DNS, session, write timeout by injae-kim · Pull Request #5156 · line/armeria

injae-kim · 2023-08-29T14:16:09Z

Related issue #4935

Motivation:

We need to make sure CancellationScheduler.finishNow(TimeoutException) is invoked on more timeout types,
such as session/connection/DNS timeout so that true is set to ctx.isTimedOut().

On A DnsTimeoutException should also set true to ctx.isTimedOut(). #4935, we found that RequestContext.isTimedout is not set true on DNS, session creation, write timeout so we need to fix it

Modifications:

Set RequestContext.isTimedOut(true) on DNS, session, write timeout by ctx.cancel(TimeoutException.class)

Result:

Now RequestContext.isTimedout is set true well on DNS, session, write timeout too
Close A DnsTimeoutException should also set true to ctx.isTimedOut(). #4935

+                        .build();
+
+                assertThat(reqCtx.isTimedOut()).isFalse();
+                assertThatThrownBy(() -> client.unwrap().execute(reqCtx, req).aggregate().join())


Suggested change

assertThatThrownBy(() -> client.unwrap().execute(reqCtx, req).aggregate().join())

assertThatThrownBy(() -> client.get("/").aggregate().join())

Hmm when I use WebClient.get("/") directly, reqCtx.whenResponseCancelled().join() not done infinitely 🤔

armeria/core/src/main/java/com/linecorp/armeria/client/ClientRequestContextBuilder.java

Line 144 in 863e27c

responseCancellationScheduler.init(eventLoop(), noopCancellationTask, 0, /* server */ false);

I guess ClientRequestContextBuilder().build() init cancellationScheduler immediately, but WebClient didn't.

armeria/core/src/main/java/com/linecorp/armeria/internal/client/DefaultClientRequestContext.java

Lines 228 to 229 in 863e27c

this.responseCancellationScheduler =

new CancellationScheduler(TimeUnit.MILLISECONDS.toNanos(responseTimeoutMillis));

armeria/core/src/main/java/com/linecorp/armeria/internal/common/CancellationScheduler.java

Line 311 in 863e27c

addPendingTask(() -> finishNow0(cause));

On WebClient, it uses DefaultClientRequestContext and it doesn't init() the ClientRequestContext's cancellationScheduler immediately.
Just add task (e.g. ctx.cancel(cause)) to pending task and execute it on init() lazily later like below.

armeria/core/src/main/java/com/linecorp/armeria/internal/common/CancellationScheduler.java

Lines 129 to 132 in 863e27c

if (pendingTaskUpdater.compareAndSet(this, pendingTask, noopPendingTask)) {

if (pendingTask != null) {

pendingTask.run();

}

But to get reqCtx.whenCancelled() completion, we need to init() cancellationScheduler.

So I used client.unwarp().execuite(reqCtx) to use ClientRequestContext.builder().build() to init cancellationScheduler~!

I'm not sure it's correct, so feel free to share your opinion! I'll update PR 🙇

I believe you can just use Clients.newContextCaptor() if you would like to get ahold of the RequestContext being used

oh I tried to use Clients.newContextCaptor() but cancellationScheduler is still not init() by this way so ClientRequestContext.isTimedOut() return false 😅

Looks good overall! Left some minor comments 🙇

Took another look at this PR.

The way I see it there are two options (or actually three):

Use log.responseCause to determine whether a request/response has timed out (or actually log().getIfAvailable(RequestLogProperty.RESPONSE_CAUSE).responseCause();)
Modify responseCancellationScheduler so that either
1.init is called at an earlier timing. Ideally, this would involve scheduling timeouts for each step (dns, connect, write, etc..) using ctx.cancellationScheduler.
2. modify the behavior so that cancel() also executes pending tasks.

I think 1 or 2-2 is probably a realistic direction for this PR. Let me discuss with the other tomorrow morning 🙇

If there's some discussion progress about direction, feel free to share to me~! 🙇

minwoox · 2023-10-10T07:06:00Z

We have decided to go with the second option. @jrhee17 is laying the groundwork for that.
#5212
He will let you know when it's done. 😉

aha~ I checked #5212. thanks for sharing!
feel free to let me know when it's ready to go with the 2. option~! 🙇

minwoox · 2024-04-02T01:08:05Z

Since #5212 has been completed, perhaps we can resume this work now?
