It looks like the file mode was changed accidentally.

mscdex · 2016-12-27T05:19:55Z

I've added dont-land-on-* labels because of the use of bind() which is only faster in node v7.

jasnell · 2016-12-27T05:23:51Z

grr.. ok, file mode should be fixed now.

While you're at it, maybe != -> !== on lines 222 and 226 below?

Would !!s !== !!newIsSpecial be better?

how about !s !== !newIsSpecial?

this[special] is guaranteed to be a boolean. s and !s are sufficient. There's no need (and no benefit) for getting fancy with it.

Updated to address nits

3rd one will never trigger?

ha! good catch... fixed!

I'm surprised that we have to do this. Isn't it like caching the length of an array before a for loop (which V8 is able to optimize)?

I wouldn't say that we have to do this. This is more a code hygiene thing for me to avoid duplicated accessor calls but beyond that the impact is negligible.

This PR will need to be updated after #10408 lands. Marking as blocked until that does.

FWIW I just noticed the file mode changed again in the landed commit.

jasnell · 2016-12-30T20:57:10Z

Ugh. My git client appears to be completely ignoring my global config setting to ignore file mode changes. Getting quite frustrated with it. Thanks for the heads up
