net: always invoke after-write callback

[addaleax]

This is part of the streams API contract, and aligns
network sockets with other streams in this respect.

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.

[mcollina]

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:

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

No problem, thanks for catching this anyway! I’ve been trying to hunt this for some time. Il giorno lun 12 nov 2018 alle 21:56 Anna Henningsen < notifications@github.com> ha scritto:

Sigh, CITGM didn’t work again.

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

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