Issue #10908 has been updated by Yorick Peterse.


@Michael

Hm, good catch, I hadn't thought of that. In that case it indeed looks like I
was misunderstanding the documentation. I'll work on the specs to
confirm or rule this out.

----------------------------------------
Bug #10908: Addrinfo.new appears to ignore the afamily argument when using a String for sockaddr
https://bugs.ruby-lang.org/issues/10908#change-51683

* Author: Yorick Peterse

* ruby -v: ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-linux]

----------------------------------------
When creating a new `Addrinfo` instance the `new` class method appears to ignore
the 2nd (afamily) argument and always sets it to `AF_INET`. Some examples:

    Socket::AF_INET # => 2

    Addrinfo.new(Socket.sockaddr_in(80, 'localhost')).afamily                    # => 2
    Addrinfo.new(Socket.sockaddr_in(80, 'localhost'), Socket::AF_INET6).afamily  # => 2
    Addrinfo.new(Socket.sockaddr_in(80, 'localhost'), Socket::PF_UNSPEC).afamily # => 2
    Addrinfo.new(Socket.sockaddr_in(80, 'localhost'), Socket::AF_IPX).afamily    # => 2
    Addrinfo.new(Socket.sockaddr_in(80, 'localhost'), Socket::AF_LOCAL).afamily  # => 2

Is this correct, or is this a bug?

The documentation states the following about this argument:

> family is specified as an integer to specify the protocol family such as
> Socket::PF_INET. It can be a symbol or a string which is the constant name
> with or without PF_ prefix such as :INET, :INET6, :UNIX, "PF_INET", etc. If
> omitted, PF_UNSPEC is assumed.

I looked at the tests but couldn't find any specific examples of this behaviour.
For Rubinius I ended up writing the following Rubyspec which currently passes on
both Rubinius (you'll need the Git master branch for this, for now) and Ruby
2.2: <http://git.io/AhpQ>. I've attached the spec as well in case the URL stops
working.
