[core-http] Throttling retry policy fix in core-http #15832

HarshaNalluru · 2021-06-17T23:04:10Z

Problem

The throttlingRetryPolicy in core-http has the potential to retry for an extended period if the service continues returning "retry after" headers on subsequent calls.

Here's the snippet of code that handles the "retry after" retries:

  public async sendRequest(httpRequest: WebResource): Promise<HttpOperationResponse> {
    return this._nextPolicy.sendRequest(httpRequest.clone()).catch((err) => {
        // other code elided....
        return delay(delayInMs).then((_: any) => this.sendRequest(httpRequest.clone()));

Solution

Update delay such that it respects abort signal.
Similar to what I had to do for app-config at #15721

is appconfiguration in beta? if not, it should not take a dep on a beta.

App-config is beta, but we may soon GA in the next couple of months.
Why is core-util in beta anyways? Can't we make that GA instead?

Because we did not settle on the public surface for it yet.

appconfig is in beta but core-http and core-amqp are not IIRC and you added core-util as a dep there. My recommendation is to keep the local implementation of delay for now and have it moved to core-util in another PR.

I really don't want to keep 3 copies of delay (core-http, core-amqp and app-config).

I really don't want to keep 3 copies of delay (core-http, core-amqp and app-config).

Why cannot App Config use the one in core-http?

Since this PR's main objective is around fixing an issue with the retry policy, can we stick to just that in this PR?

@ramya-rao-a So, you're suggesting core-http and core-amqp would have delay? Can do that if weare fine with 2 copies.

(What's the point of core-util then?)

What's the point of core-util then

It is pending the on the conclusion on the discussion we had today on the subject of code sharing

We now have two copies of (advanced) delay.. core-amqp and core-http.

Logged #15930 for core-util discussion.

value?: T should be the 2nd argument, otherwise this would be a breaking change.

Good point.

I'll switch to that.
What about the core-amqp counterpart? How to get the copy of this method to stay consistent? Does that mean we can only bring consistency if we upgrade to a major version?

@HarshaNalluru I think there is no need to care about their consistency, we can just ignore them once core-util goes GA. Also, core-http is going to be phased out fairly soon anyway.

Thanks for the fix!

why is this assigned? I don't see it getting assigned back to undefined can we just declare the method in scope?

I just copied this from core-amqp.

Can be done, will do.

Linter complains about this. Reverting.
