Apply service naming flow to messaging integrations by jbertran · Pull Request #2961 · DataDog/dd-trace-js

jbertran · 2023-04-03T14:13:37Z

What does this PR do?

Apply the new naming flow introduced in #2941 to all messaging integrations.

In source, this just requires using the TracingPlugin methods for naming resolution.

In tests, this means defining the expected naming per version and performing relevant tests for both v0 and v1, using the withNamingSchema fixture.

Motivation

After the introduction of #2941 , we want all plugins to be sensitive to the naming schema.

-        'amqp.connection.user': address.user
-      }
-    })
+    this.startSpan(


I remember you and Roch talking about minimizing the line diffs in the plugins. Did the linter complain about this:

this.startSpan(this.operationName(), {

Oh, I see you did follow this pattern later in the PR. Looks like there are several places where this can be applied.

This PR was a follow-up to #2941 (which is the one we iterated on). I was waiting on the merge of #2941 to rebase this one on top, to minimize the amount of extra work, but it sounds like we're pretty close so I'll take care of it now.

tlhunter · 2023-04-18T22:39:35Z

Do you know if we're lucky enough now that all of the plugins pass this.operationName() as the first argument and the same .service pattern in the second argument?

If we were lucky then we could refactor startSpan like so:

startSpan ({ childOf, kind, meta, metrics, resource, type } = {}) { name = this.operationName() service = this.config.service || this.serviceName({ service: this.tracer._service }) const store = storage.getStore()

If not, I then wonder if it's a common enough pattern that would could introduce some sort of wrapper that maybe filled in the blanks:

startSpanWithDefaults (obj) { let name = this.operationName() let service = this.config.service || this.serviceName({ service: this.tracer._service }) return this.startSpan(name, {...obj, service}) }

Then again, it might just be another annoying layer of abstraction. Wdyt @rochdev?

Name and service are indeed common as far as I've seen, it's just that the service name override config.service || this.serviceName occurs at different levels in the hierarchy depending on the plugins. I think we should be able to make this behaviour common, but I'd like to update all relevant plugins to use the naming schema before tackling that, to have a clearer picture of where the pitfalls are (if any).

      loadChannel.publish({ name: 'four' })
      expect(instantiated).to.deep.equal(['two', 'four'])
    })
+    it('configures service naming schema resolution', () => {


I wonder if we should break this up:

const Nomenclature = require('../../dd-trace/src/service-naming') // top of file? describe('configures service naming schema resolution', () => { const config = { foo: { 'bar': 1 }, baz: 2 } let configureSpy beforeEach(() => { configureSpy = sinon.spy(Nomenclature, 'configure') }) afterEach(() => { configureSpy.restore() }) it('works', () => { pm.configure(config) expect(configureSpy).to.have.been.calledWith(config) }) })

The expect() call throws IIRC, and basically the test can fail for other reasons and not get to the part with the restore. By throwing the cleanup in an afterEach (or after) it then prevents a situation where a failed expectation pollutes the future state of the tests.

Done in #2941

tlhunter · 2023-04-18T22:46:32Z

I left a bunch of small comments but I think it's architecturally good and overall pretty close.

rochdev

The overall design LGTM, just a few comments on minor things that could be improved, especially given that this will touch every plugin eventually.

rochdev · 2023-04-19T20:45:17Z

Do these need to be functions? Accepting an object could make this easier also when an override is not needed, for example withNamingSchema(() => {}, namingSchema.send).

With the way the tests are performed, they do need to be functions. I'm open to other ideas since I'm not a huge fan either 😅

namingSchema is a proxy that resolves the v0/v1 part of the naming schema, so it must be accessed inside the test case, because the configuration change that controls v0/v1 is kept at the test case level.

rochdev · 2023-04-19T20:54:45Z

Not sure I understand this, that definitely doesn't sound like a direction?

Also, is this actually used somewhere?

Agreed, this ioDirection should probably be more generically named. subType sounds a bit too generic to me, WDYT?

Of all 3 AMQP integrations, this one is special because it's auto-instrumented based on a defs.js file generated by the library, which includes control-plane calls for managing exchanges and queues. These get their own amqp.command operation name, which has to go somewhere that's neither inbound nor outbound in the naming schema.

The fact that it's a control plane then can be inferred by type=worker + kind=client.

Done in 50b1fe7. Client integrations will get updated, so I'll generalize this part to client integrations when they're all updated.

rochdev · 2023-04-19T20:58:26Z

This is redundant with both the span kind and the IO direction, and could be set in the base class for most cases. Can we settle on just 1 and make sure that everything is normalized accordingly?

Span kind can be integrated in startSpan for consumer and producer plugins. For this specific one, since it's a client we can't bake it in until we've dealt with all clients, and we're in the rare case where the client is specifically a messaging client (most will be HTTP or database), so setting it here seems like the best we can do.
