Fixes #8555

style: I think indentation should be 2 spaces here

Thanks for catching it! I keep forgetting that ESlint doesn't complain about C++ formatting. Does anybody want to share their vimrc with me for correct auto formatting?

style: align with previous argument ?

The indentation looks off here.

I'm not sure about the second part of this error message. If we can't say with certainty what the problem is, I don't think we should leave questions like this.

Maybe we could then check if the file limit was actually reached?

I was trying to make the message more helpful than just saying that the call failed. But I'm also OK with deleting the second part.

Should it say "initialize uv loop"? To give more context?

Maybe we could then check if the file limit was actually reached?

That would be pretty nice. I’m not sure whether that’s feasible to do in a cross-platform way, but for POSIXes it probably would work.

Yeah, I think @addaleax is right that it may be difficult to do x-platform reliably. The message could be extended a bit with something like, Failed to initialize loop. This may be caused, for instance, by reaching the file limit.

sorry to bother you, but indentation is still off by 1.

No problem, my fault for being sloppy.

imyller · 2016-09-18T09:50:37Z

Oh, @thealphanerd do you feel citgm should be run before landing this?

addaleax

LGTM but the commit message should start with vm: or maybe src:?

(I don’t think CITGM is really necessary here, but if somebody wants to run it, sure)

I think this line can be dropped.

fhinkel · 2016-09-20T09:33:28Z

I fixed the formatting, error message, extra CHECK, and commit message.

CI again: https://ci.nodejs.org/view/All/job/node-test-pull-request/4146/

jasnell · 2016-09-20T18:41:31Z

I don't believe it needs to be but should this be semver-major?

cjihrig · 2016-09-20T22:21:42Z

I don't think this should be semver major since it's an abort. I'd go with patch.
