There was a problem hiding this comment.
FatalException() can return so this should probably be followed by an ABORT() or something. The unguarded value->IsTrue() below is not safe, at any rate.

@bnoordhuis Yea, thanks. 👍 I’ve added an extra return true; here and UV_EPROTO as the default return value for the other places, that’s what tls_wrap.cc uses as a generic failure code (but feel free to let me know of a better choice) – it shouldn’t make any difference in practice, I guess.

CI failures are all infrastructure failures … Windows is pretty bad but I’d still go ahead with landing this, this isn’t too platform-specific code and it at least does compile successfully there. |

This seems like something we would want to backport, but perhaps wait a bit of time for it to harden. Thoughts? |

@addaleax I've backported to 8.x, please lmk if this should be backed out |
