[mathiasbynens]

This patch updates Punycode.js to v2.0.0. It drops support for old and non-Node environments. This fixes#7224.

Out of curiosity, what does this function do to strings like 'foo@bar@baz'? Drop the @baz part?

[MylesBorins]

Looks like a bunch of failures

@mathiasbynens Please steal this patch. I hope the tabs get through alright.

EDIT: They don't. The spaces before the throw and the caret should be a single tab.

Patch stolen. Thanks, @bnoordhuis!

ci again: https://ci.nodejs.org/job/node-test-pull-request/2977/

[mathiasbynens]

I still managed to mess up the tabs somehow, sorry about that. The amended patch passes all tests. Can you kick off CI once more please?

[bnoordhuis]

CI: https://ci.nodejs.org/job/node-test-pull-request/2989/ (one of the ppcbe buildbots appears to be stuck so it's possible the run doesn't show up as complete within a reasonable amount of time.)

EDIT: Also, LGTM.

[silverwind]

CI is basically green, LGTM.

Thanks! Landed in b77eb8c.

@mathiasbynens @nodejs/lts backport to v4.x?

[mathiasbynens]

@thealphanerd Note that Punycode.js supports Node.js v6+ only. It may work on Node.js v4 as well but no such guarantee is made. It might be better to leave v4.x as-is, especially since Punycode.js v2 doesn’t add any new functionality.

Marking as don't land
