Why these changes?

Because without them it will accept false without throwing, which I assume is not the expected behaviour

I see. Can we at least use init !== undefined instead? That is the form we use elsewhere in core.

Can you re-phrase these using assert.throws? e.g.

assert.throws(() => { async_hooks.createHook({ init: 1 }); }, /^TypeError: init must be a function$/);

(Also, please make sure that make lint passes :))

Thanks! I have updated the commit.

Is this block copy-pased or did you check that it is necessary?

Shame on me, completely copy-pasted and unnecessary. I have updated the commit.

Thanks for taking the time to fix this.

Could you add those details to the commit message, "test: add constructor test to async-hooks" is a little vague. Since this changes something in the actual async_hooks code you should also prefix the commit message with async_hooks: instead of test: .

@Shadowbeetle you gave false as a previously failing argument. Could you add a set of tests with false?
This could be done in a double loop:

for (let badArg of [1, false, true, null, undefined, 'hello']) { for (let field of ['init', 'before', 'after', 'destroy']) { assert.throws(() => { async_hooks.createHook({ [field]: badArg }); }, /^TypeError: before must be a function$/); } }

@refack Thanks, I have included this with a minor change in the commit.

I think the dangling , is a lint error

Shadowbeetle · 2017-05-19T12:34:41Z

Sorry, an extra space sneaked in that broke the lint

AndreasMadsen · 2017-05-19T13:40:55Z

@Shadowbeetle Sorry if what I said was poorly explained, but we need to conform to the commit message guidelines, you can read them here https://github.com/nodejs/node/blob/master/CONTRIBUTING.md#commit-message-guidelines

Something like this should be fine:

async_hooks: add constructor check to AsyncHook

This fixes the async_hooks.AsyncHook constructor such that it throws an error
when provided with falsy values other than undefined.

@AndreasMadsen I see, sorry I should have read the guidelines more thoroughly. Updated the commit message.
