process (util?)

Description of change

Until now, the docs stated that process.noDeprecation could be set at runtime, but before any modules were loaded. That was not true, because lib/internal/util.js was loaded during the process startup process, so setting the flag at runtime was always pointless.

Minimal test case:

process.noDeprecation = true;
process.EventEmitter;

This patch moves checking process.noDeprecation to the place where it was actually used.

test/parallel/process-no-deprecation.js

Can you add a check that calling printDeprecationMessage() after setting process.noDeprecation to false again does emit a deprecation warning?

bnoordhuis · 2016-05-11T08:48:30Z

Nice, LGTM.

If I am not wrong this function should not be called right? I think assert(false, 'this should not be called'); or something like this would be better I guess.

addaleax · 2016-05-11T14:32:00Z

Updated based on @thefourtheye’s suggestion.

Mostly LGTM, good catch.

addaleax · 2016-05-11T15:39:49Z

@Fishrock123 looking better now? :)

Unused warning?

@Fishrock123 eh, yes, sorry. fixed.

Fishrock123 · 2016-05-11T16:10:12Z

Yeah. Another CI would be nice before landing once that nit is fixed

test/parallel/test-process-no-deprecation.js

this could fail if any other warnings happened to be emitted in the future. The warning object can be checked to see if it is a DeprecationWarning by looking at the name property or the message can be checked explicitly.

That's unlikely though, is it? That would mean core is doing something internally that is worthy of warning. I'd consider that a bug.

Wasn't commenting on the likeliness of it... just the possibility of it. ;-)

@jasnell lol, literally what I had written here at first. But @thefourtheye made a good point, if there are other warnings emitted in the future, it’s probably best to know about that, even if that might mean having to change the test file again.

;-) ok @addaleax ... sgtm
