[v10.x] Revert "http: always emit close on req and res" #21809

targos · 2018-07-14T10:57:05Z

This also reverts 2a9c833 which modifies the added file and line.

Refs: #20611 (comment)

/cc @nodejs/tsc

The change landed in v10.2.0. I suppose there is a risk to break code that is now relying on it?

I would prefer if this is a @nodejs/tsc decision. Should we put it in the agenda for next week?

targos · 2018-07-14T11:15:38Z

Sure. Added the label.

Node.js 10 has had the change for almost twice as long as it didn’t have it, and we’ve done security releases since then (i.e. we expect people to use versions that have it)… not knowing much about the subject matter, I’m not sure reverting is ideal?i

mareksrom · 2018-07-15T10:42:48Z

From different point of view - since 10.2.0 it was an undocumented API change, it became part of the documentation in version 10.6.0 just 10 days ago... How about projects relying on the previous documented version added in 0.6.7 released in January 2012? I think the number of them will be slighly bigger;)
I know it is not popular to do that, but SEMVER does not say could or should but MUST and we all know why (even though sometimes it doesn’t taste well:).

targos · 2018-07-18T17:17:03Z

Note from TSC meeting: we also need to revert the documentation change.

mhdawson · 2018-07-18T17:20:48Z

From the discussion in the TSC meeting I'm +1 to reverting.

mcollina · 2018-07-18T17:21:17Z

This is the documentation change #21047.

Trott · 2018-07-18T23:44:59Z

Was there a resolution in the TSC meeting? Should the tsc-agenda label be removed? Or is it slated for next week's meeting too? /cc @targos

mcollina · 2018-07-19T07:15:55Z

@Trott we did not have quorum. The proposed path is to revert this in Node 10, but leave it in in master.

This approach would need necessarily 2 TSC signoffs because it's a retroactive semver-major change that should not have landed in master without 2 TSC signoffs.

This reverts commit 2a9c833.

This reverts commit 8029a24.

This reverts commit 8ab7ea6.

targos · 2018-07-19T07:27:48Z

Doc change reverted

mcollina

LGTM

targos · 2018-07-19T09:07:22Z

CI: https://ci.nodejs.org/job/node-test-pull-request/15944/

Is this going to break end-of-stream again?

mcollina · 2018-07-19T09:36:40Z

@targos I do not think so. What broke eos was 8029a24.
Moreover we are testing the same logic within stream.finished here. I'm confident that we are not breaking anything if CI passes.

cc @mafintosh to confirm before landing.

mafintosh · 2018-07-19T12:19:04Z

eos is fine with this. LGTM

targos · 2018-07-20T16:28:28Z

CI is green. This needs at least one more @nodejs/tsc signoff.

MylesBorins

Rubber stamp LGTM

mcollina · 2018-07-30T15:00:20Z

@nodejs/release @nodejs/lts I think this is ready to land.

targos · 2018-08-01T08:00:45Z

I'm going to add this to the release proposal at #22040

targos · 2018-08-01T08:01:44Z

It's probably worth a sentence in the notable changes. Could someone help me write it?

ruiaraujo · 2018-08-01T09:43:28Z

Since this is already released, reverting it would just make a bad situation worse.

SEMVER was already broken once with the initial release, reverting it would just break it again.

targos · 2018-08-01T12:18:56Z

I've added this back to the TSC agenda to discuss in today's meeting.

MylesBorins

+1 reverting is the right move. This is something we should fix before LTS

mhdawson

LGTM

I feel the conflict here is which of the following we want to make migration from easier:

Earlier v10.x versions
Versions older than v10.x

Since v10.x is an LTS version, but we haven't reached LTS stage, there's still a lot of life remaining in v10.x as folks try to update to v10.x from versions older than v10.x.

It's a sucky situation, but I'm on the side of 👍 on this PR as well.

This reverts a commit that accidentally introduced a semver-major change to Node 10 and broke userland code. A subsequent fix to that change and documentation change are reverted with it. Revert "http: fix res emit close before user finish" This reverts commit 2a9c833. Revert "http: always emit close on req and res" This reverts commit 8029a24. Revert "doc: fix HTTP req/res 'close' description" This reverts commit 8ab7ea6.
