I need IPV6 sockets and after a short glance over Socket code and a search in files it seems that there is no such support.

If this is the case and it is not planned to add such support, I'll need to hack together something like this ASAP, in the weekend at the latest.

Indeed, it is currently "nil".

I would be happy to improve Socket based on your code...

I managed to get some basic IPv6 support working. Socket and HttpClient seems to work fine. I kept the API the same, but I changed in Socket::Data:
bool                    Open(bool is_blocking, int family = PF_INET);

Also, OpenClient has a parameter "dword *my_addr". If you supply an IPv6 address a dword is no longer sufficient storage.

I'll do some more tests and prepare a patch.

PS: I am not very familiar with Web package. Adding support for IPv6 to socket and making HttpClient recognize the addresses solves most issues. Are you aware of other classes that need my attention? Or maybe other packages?

Well, very quick review of the issue indicates quite likely only small difference - wherever there is

AF_INET

there should be

AF_INET6

for ipv6 support and the structure involved should be 'sockaddr_in6' instead of 'sockaddr_in'.

Sorry for the late reply. Here's the problem: our company is transitioning over to IPV6 for its entire product range and this is a monumental task. So I could only spare a little time on this task, and once I fixed the issues that prevented me from using U++ as an IPV6 client I could not find time to develop support for server mode also. I can't do it in my free time on non work related tasks because I don't have access to any non IPV6 networks.

But I'll share here the changes I've made. They look hacky but were very thoroughly tested in GUI and automated test mode.

There was an issue about the time IPv6 was introduced.
http://www.ultimatepp.org/forum/index.php?t=msg&goto=320 66&#msg_32066

Mirek was able to track the problem down and fix it, I don't know if IPv6 was involved.

It was compiled in Win and worked OK.
Running on Ubuntu with Wine was the problem.

If your code can be pasted into the SDK overwriting the current code I will try it, it may be a few days before I can get to it.

I don't know about that issue, but here is a merge for the hack I'm am using for IPV6 clients made with U++ 4552.

I hope that some day I'll have time do do a proper fix and add support for IPv6 servers too Smile.

One note: I plan to refactor Socket and its implementation; I hope that will be a good time to add IPv6 support as well.

The main reason for refactoring is that I believe that SSLSocket : Socket hierarchy is wrong. The goal will be to add SSL as "feature" of normal Socket. It will greatly simplify the whole Socket implementation and it is also more correct (I have had a quite hard time trying to implement HTTPS proxy recently...).

Good to know! I will test it when it's done because we have moved away from IPv4.

I did not put any great effort into my implementation: it just works (if I didn't mess up the merge).

With the current refactoring of the web packages do we have now support for IPv6? A very brief inspection of sources hints toward yes.

Yes. Sorry for not mentioning it in Development blog.

The only problem I have encountered is that ipv6 for server has to be activated by bool variable.
