As brought up in nodejs/v8#2 I'm quite skeptical this is a good idea until we get better hooks for native promises. (Which seemed to be the plan to get in before node version 8, where this was originally supposed to land.) |

CI run to validate across platforms: https://ci.nodejs.org/job/node-test-commit-v8-linux/421/ |
That's a pretty cryptic comment on its own. I think the missing context is that 5.5 ships async/await without a flag? |

Looks like CI failures across the board. |

Updated. There are some new utf-8 fixes (1, 2) that make Example failure: test('utf-8', Buffer.from('F0B841', 'hex'), '\ufffd\ufffdA');
// AssertionError: Expected "\ufffd\ufffd\u41", but got "\ufffd\u41"If I change the expected value, the error is inverted: test('utf-8', Buffer.from('F0B841', 'hex'), '\ufffdA');
// AssertionError: Expected "\ufffd\u41", but got "\ufffd\ufffd\u41" |

I'm turning the PR into a clean semver-major that can land on master. I'll then open another one to backport to v7.x. |

This is still in progress because of v8@af842a7#commitcomment-19855022 |

@nodejs/platform-smartos What are we going to do with SmartOS 14? The CI cannot be green because of the incompatibility with this platform. |
|
@targos as far as I know, it is to be dropped for 55 and forward. I can look at skipping testing against smartos14 for a specific node version; for instance 7.3? |
|
@targos FWIW, what @jbergstroem mentioned:
sounds good to me. P.S: sorry for the delay, I was on vacation until today. |

V8 5.5 changed how invalid characters are handled and it now appears to follow the WHATWG Encoding standard, where all of an invalid character's bytes are replaced by a single replacement character (\ufffd) instead of replacing each invalid byte with separate replacement characters. Example: the byte sequence 0xF0,0xB8,0x41 is decoded as '\ufffdA' in V8 5.5, but is decoded as '\ufffd\ufffdA' in previous versions of V8.

Landed in a67a04d...24ef1e6. Thanks everyone! |

Is this means we can use async/await safely? |
|
Will it be included in version 8 without flags? |
|
@leodutra It is already in master branch, thus in Node.js 8 |

@targos https://github.com/nodejs/node/blob/master/BUILDING.md#unix still mentions Clang 3.4 as the required version. Do you know what the new required version is? |
|
@joaocgreis I don't know what is the actual required version but since we dropped the workaround from #8343 it must be at least 3.4.2. |
