I’d like to land this today or tomorrow.

@nodejs/tsc @nodejs/streams Just pointing out that this does change a test, and I won’t mind if anybody wants to label this semver-major because of it.

I was thinking this when I approved the PR, but didn't mention it. I think I'd be +1 to semver-major.

LGTM, let’s consider it a bugfix. I would be careful with backporting.

A CITGM run would be helpful.

I would prefer to have a test on net that verifies this.

The previous CITGM run had infra issues similar to what we’ve seen before, cc @nodejs/build-infra again

@mcollina I’m not sure how to write a simple net-only test for this that doesn’t have the complexity of the test that is being modified here. This doesn’t seem to do the job:

const server = net.createServer(common.mustCall((connection) => {
  connection.end('foo');
})).listen(0, common.mustCall(() => {
  const client = net.connect(server.address().port);
  client.write('bar', common.mustCall(() => server.close()));
  // client.end();
  client.destroy();
}));

Sigh, CITGM didn’t work again.

New attempt: https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/1617/ (scheduled)

Landed in c347e77

I’ve added the dont-land-on-lts labels, if that’s okay with everyone.
