The _debug of Module is undocumented and it useless here.

This one has been there for so long we might need to do a deprecation cycle on it. Marking semver-major defensively. Ping @nodejs/ctc

(to clarify, I would highly doubt that it's being used, but it pays to be safe)

This needs some more reviews from @nodejs/ctc

@jasnell I guess it is safe to land this as is?

Perhaps we should ping @ChALkeR and ask him to please please please do a quick ecosystem search, just to be safe. We should also do a CITGM run just in case. It also needs CI

Can we deprecate this like we normally do? It shouldn't cost anything. If it does, we will get complaints which will show it is being used.

It wouldn't hurt to deprecate it.

Yep, I'm good with a regular deprecation.

Thanks all. I will change to deprecate it first.

Would you mind escaping the underscore?

This should actually be DEP00XX until it lands. The person landing needs to assign the specific code.

And the

Module._debug = util.deprecate(debug, 'Module._debug is deprecated.',
                               'DEP0076');

should be DEP00XX also?

Yeah, all of the DEP00.. identifiers.

Hi all, I have updated this PR.

@evanlucas the PR was updated with your suggestion. PTAL

Our deprecation guidelines don't cover this. So I'll just ask here. Do we allow an undocumented API to be runtime deprecated directly without documenting and deprecating first?

@BridgeAR

@thefourtheye that is a good point. I guess we should go ahead and improve the deprecation guidelines. I personally do not feel like it is the right thing to do to document a so far undocumented feature with the goal of actually removing it at some point as that is somewhat counterproductive.

I think it's likely safe to dismiss @evanlucas' objection since this was changed to a deprecation as he requested. Evan is on vacation right now so may not be able to rereview soon

Yes, so long as deprecations.md is updated appropriately.
