src/inspector_agent.cc

-    worker_agent_.reset();  // Dispose before the dispatchers
+    if (worker_agent_) {
+      worker_agent_->disable();
+      worker_agent_.reset();  // Dispose before the dispatchers


Btw, if you need member fields to be destroyed in a specific order, it might make the sense to re-order the fields so that that happens automatically?

I would like to have this specified explicitly so I don't cause crashes by moving fields in the header file. Had that happen before :)

test/parallel/test-inspector-workers-flat-list.js

+}
+
+function runWorkerThread() {
+  let worker = null;


Can you rename this to child or childWorker to be more explicit?

test/parallel/test-inspector-workers-flat-list.js

+
+let rootWorker = null;
+
+function runTest() {


const runTest = common.mustCall(() => { ..., to make sure that this is actually run?

test/parallel/test-inspector-workers-flat-list.js

+  let reportedWorkersCount = 0;
+  const session = new Session();
+  session.connect();
+  session.on('NodeWorker.attachedToWorker', ({ params: { workerInfo } }) => {


ditto here, common.mustCall(..., MAX_DEPTH) for the event handler to make sure this actually runs as often as expected?

I didn't investigate to confirm, but the CI results look like there are relevant failures when running tests from workers (with tools/test.py --worker). https://ci.nodejs.org/job/node-test-commit-custom-suites-freestyle/8271/testReport/

Putting in a request changes so no one lands this without noticing that there's a CI failure that needs to be addressed.

eugeneo · 2019-07-29T16:17:46Z

@Trott thanks for reminding! Those two tests should not run in a worker as child workers are now reported from the top level only.

test updated

Looks like parallel/test-inspector-workers-flat-list fails everywhere now because it uses common.skipIfWorker() but also new Worker(__filename). It needs to either launch a worker in some other file or else be able to detect if it was launched from this file (say, by checking for a specific value in workerData) and not skipIfWorker() in that case.

I took the liberty of committing the fix for that myself. Hope that's OK. If not, remove my commit and add your preferred change.

Well, that's what I get for using the GitHub interface as an IDE. Let's try again...
