Feature/fix freebsd build #332
Conversation
clang++ on FreeBSD was blaming v8 for using invalid casts from nullptr:
reinterpret_cast from 'nullptr_t' to '...' is not allowed
Replace casts with NULL, or NULL with 0 where applicable.
fix nodejs#324
FreeBSD does not support V4MAPPED.

Maybe #ifdef on AI_V4MAPPED? It's probably an issue on DragonFlyBSD as well, maybe the other BSDs too.

The flag itself is present, unfortunately.

I remember that it was broken in FreeBSD 8 but I would be sad and surprised if it's still broken in FreeBSD 10. Could it be that the tests fail because we allow V4MAPPED with IPv4 queries? Does the patch below fix the test?

Nope, it won't help. The source of the problem is here: https://github.com/iojs/io.js/blob/v1.x/lib/net.js#L894-L900

That looks plain wrong to me, it must have worked purely by accident on platforms that are a little more forgiving. I suggest dropping this change and filing an issue for the V4MAPPED bug.

Well, the problem is that server.listen() does not work on FreeBSD. May be we could land it this way and open the issue?

Please add a FIXME comment explaining why this hack is currently needed.

Oh, and I might have pasted the wrong code on IRC; I think that should be &&, not ||. Mea culpa!

The V8 patch should be upstreamed because V8 master seems to be affected as well. @indutny You want to do that? Or maybe @jbergstroem can shepherd it? |

@bnoordhuis I'll figure it out |
|
@bnoordhuis please check again, pushed the fix. |

Close enough, I guess. (It's libc, not the kernel. Details...)

LGTM. Please file an issue for the V4MAPPED thing. |
