IPv6 Support For LuaSocket

mertocan

Hello,

From now on, apple doesn't accept any updates or new apps without ipv6 support. Do we have to update luasocket or socket.lua files for this? Or is it already implemented?

Thanks

By the look of it gideros uses a quite old version of luasocket which doesn't support IPv6.
Newest luasocket (2.1) claims to have added IPv6 support, time for an upgrade into gideros maybe ?

mertocan

How can I upgrade it?

You will need to build it as a gideros plugin, and for this you need all the tools for building gideros itself from sources. Gideros luasocket plugin is here: https://github.com/gideros/gideros/tree/master/plugins/luasocket, while newest luasocket sources can be downloaded here: http://www.luatex.org/svn/trunk/source/texk/web2c/luatexdir/luasocket/doc/index.html#download.

If it is a requirement for iOS, then I may need to have a go at it too since my app use luasocket.

From the Github it's near 3.0

It is requirement for iOS. We wont be able to update apps without ipv6 support.

But, I still dont know how to update luasocket in Gideros. Isnt it possible to make new version of Gideros with new luasocket any time soon?

I really need to update it Apple declines my app.

As per article you posted, I think you don't need to update luasocket at all.

1) use server names (like domain or hostname for local connections) instead of server's ip address
2) change ip function to getaddrinfo function if you are using it.

And Url loader uses one ios internally uses, so if their API ar compatible with ipv6 then so should be UrlLoader

Does the current luasocket has socket.tcp6 function to connect ipv6 ?

SinisterSoft

broadcast doesn't exist on ipv6 (as far as I'm aware), so if running on an ipv6 only network and you do broadcast then you have to change that too.

ar2rsawseen

I have not tested or done anything related to ipv6 but again from your posted link, tcp function should work just fine, if you use servername and not ip directly.

The main problem is that majority of webservers out there are using ipv4,
so if apple would really do what they say they do, it means you would not be able to browse any website on your ios phone.
So they would never do that.

They seem to be only blocking using hardcoded ip addresses which are in ipv4 format. And thats it. All the rest should work as expected.

Okay I got it now. But I am using ip address to connect socket. Because I have multiple servers for game play. When game initialized my main server(with domain name) sends ip address for socket connection which is ipv4. I need to find solution for it I guess.

Thanks for help btw.

SinisterSoft

just create one subdomain per ip address and point to each of them. Then allocate them as you do, but give them the server number instead.

Hi again,

UrlLoader is working but socket.tcp method returns not connected error even if I am using host name with a port.

address is: onlinewordhunt.com
port is : 105

function connect(address, port, laddress, lport) local sock, err = socket.tcp() if not sock then return nil, err end if laddress then local res, err = sock:bind(laddress, lport, -1) if not res then return nil, err end end local res, err = sock:connect(address, port) if not res then return nil, err end return sock end

mertocan

Actually I am using Noobhub. Do you have any idea about the solution @Overtorment ??

SinisterSoft

Maybe Noobhub only works with ip v4 ?

totebo

@mertocan, did you get Onlinewordhunt to use ipv6 in the end?

mertocan

Yes, looong time ago. It was fixed by updating luasocket plugin.

totebo

Great stuff. I also got it working, using the new dns.getaddrinfo in LuaSocket 3.
