Tech,
Now that my AI_ADDRCONFIG diff is in, it's time to reveal my evil master plan:
make getaddrinfo() return IPv6 results first by default.
The diff below would be the end goal. I guess people will have valid objections
to it. I'd like to know what they are.
Would it be necessary/desirable to check all calls to getaddrinfo() in base and
add AI_ADDRCONFIG to hints.ai_flags where needed? (i.e. pretty much everywhere
except special cases which right now I can't think of any)
Thanks,
Simon
