Description of change

res and abort fields are now defined in the constructor and not suddenly appear during the runtime. This makes hidden class stable and the heap snapshot more verbose.

Ref: #8912
PR-URL: #9116

This change doesn't affect anything, but I found two different ways across the single constructor: self and this. Seems it should be consistent but I don't know the agreement about it.

@bnoordhuis didn't you mention in another issue recently that we should prefer this and an arrow function over self?

If we're setting this to zero now, we should both remove ClientRequest.prototype.aborted = undefined; and change the if (this.aborted === undefined) check to if (!this.aborted) below.

Perhaps we should also change delete req.res later in this file to req.res = null?

vitkarpov · 2016-10-16T20:26:32Z

@mscdex made some fixes after review:

removed aborted from prototype, it's unnecessary anymore
the right check for this.aborted
do not delete res from object anymore, just null it

Also, started to use this, not self in the constructor

Guys, why do windows tests fail? Seems it's not the result of this changes, considering it's about JavaScript code, isn't it?

mscdex · 2016-10-17T07:56:31Z

@vitkarpov In this case, the Windows failure is the result of a CI infrastructure issue and is unrelated to this PR.

I'm not sure why aix failed though, it seems it couldn't find the built node binary for some reason. /cc @mhdawson ?

The ARM failure looks unrelated.

vitkarpov · 2016-10-17T08:22:26Z

Yep, I've noticed that some other prs behave the same.

vitkarpov · 2016-10-25T17:27:00Z

Guys, what's gonna happen with this pr? I'm ready to rebase the branch when it will be about to be merged, but I'm not sure about the process (there's not milestone tag or something).

cjihrig · 2016-10-25T17:32:54Z

Minimally, this needs a rebase, collaborator approval, and a new CI run.

@vitkarpov
A couple of things to note:

All of these assignments (including the existing this._ended = false) need to happen earlier in the constructor before any possible early returns. I would suggest placing them before these lines in the constructor:

  var called = false;
  if (self.socketPath) {
  // ...

These also need to be added to the constructor:

  this.timeoutCb = null;
  this.upgradeOrConnect = false;

vitkarpov · 2017-01-06T15:50:34Z

@mscdex Done.

CI is green, except for an unrelated CI infrastructure failure.

LGTM.

I think there are additional properties to add:

this.parser = null
this.maxHeadersCount = undefined

MylesBorins · 2017-11-14T18:39:38Z

As this has not been backported I'm setting to dont-land

In Refs, http.Server's maxHeadersCount field was defined in the constructor to make hidden class stable and so on. Also in https.Server, we can use maxHeadersCount the same as http via connectionListener. So, defines it in the constructor and documentation. Refs: nodejs#9116
