doc: documentation deprecation of process.binding #22004

jasnell · 2018-07-27T15:57:35Z

This is the first step in a long process of deprecating
process.binding() and replacing it with internalBinding().

Eventually, once we have replaced internal uses of
process.binding() with internalBinding(), we can escalate
to a runtime deprecation and eventual end-of-life.

+Type: Documentation-only

+The `process.binding()` API is intended for use strictly by Node.js internal
+code to provide a bridge between Node.js' JavaScript and native code layer.


It might be best to avoid the possessive by removing a couple words so it becomes: bridge between JavaScript and native code.

Even better perhaps is remove everything after code from this sentence. You don't have to explain what the function does. That's superfluous information in this case.

+Use of `process.binding()` by user-land code is unsupported.


AFAIK, we use userland everywhere and user-land nowhere, so let's stick with userland.

Nit: remove strictly

It's unnecessary. It's also imprecise. "only" would be more precise.

So maybe this?:

process.binding() is intended for use by Node.js internal code only.

Trott · 2018-07-27T17:52:07Z

Putting all my nits together (and one or two that I didn't leave), the wording might be simplified to:

process.binding() is intended for use by Node.js internal code. Use in
userland code is unsupported.

...or (adding one word more):

process.binding() is intended for use by Node.js internal code only. Use in
userland code is unsupported.

ChALkeR

We needed this for a long time.

Technically, it was never part of a documented public API afaik so we could just move to runtime deprecation, but given that the usage (of certain modules) was widespread, it seems to be a good decision to doc-deprecate it first.

ChALkeR · 2018-07-27T20:05:34Z

@jasnell Perhaps DEP0103 text should be updated (in the «should be avoided» part) to mention this deprecation?

jdalton · 2018-07-28T02:46:12Z

I'd be great to make some things, like process.binding('config'), accessible in a more user-friendly way. As we move thing along we should try to examine what folks have found handy (to cause them to reach for these internals) and try to fill the feature gap in a more polished way.

mcollina · 2018-07-28T03:47:31Z

@jdalton can you please open an issue on how you use process.bindings(‘config’), and what would you need to have as a public API? Thanks!

by Node.js internal only code -> by Node.js internal code only or only by Node.js internal code.

fixed the word ordering

ChALkeR · 2018-07-29T21:28:59Z

What about DEP0103?

jasnell · 2018-07-29T22:29:02Z

Ah, right, yeah I'll update the description for that

ChALkeR · 2018-08-01T14:49:13Z

@jasnell Is it supposed to include the deprecation codes as DEP00XX?
Are those assigned at the time of a release, or was that not deliberate?

targos · 2018-08-01T14:51:26Z

The deprecation number should be assigned when the PR is landed.

jasnell · 2018-08-01T14:52:18Z

Doh... Missed the step in landing. I used to have that in my local checks but I got rid of those when switching to node-core-util. Completely forgot about it. Will do a fixup pr

ChALkeR · 2018-08-01T14:53:58Z

@targos @jasnell Apparently, that doesn't work :-/.

As the space of deprecation codes is pretty high, perhaps we could assign codes at PR open time instead and add a test for those? Would holes or out-of-order landing of deprecation codes hurt?

jasnell · 2018-08-01T14:55:56Z

It would be helpful if node-core-util could handle it :)
