Remove ToxDNS and related stuff from toxcore about c-toxcore HOT 11 CLOSED

If name lookups can leverage the DHT and be done in a fully distributed way then it's obvious why it would belong in toxcore. However toxcore shouldn't go anywhere near dealing with servers/third party services.

I'll remove it when qTox removes its use of the toxdns library.

No, name lookup shouldn't be handled by toxcore.

@tux3 would qTox mind if toxdns were gone?

from c-toxcore.

qTox is using HTTPS lookup, so it shouldn't be a problem.

from c-toxcore.

Since qTox supports the HTTPS "toxme" API, we should be able to remove toxdns3 support without problems.
The HTTPS system still suffers from the same centralization and trust issues (it's arguably worse since we don't support key-pinning), I think we'd all be happy to have a secure replacement without sacrificing the convenience.

Specifically, I will remove toxdns when no actively maintained client and library uses it anymore. It has very low maintenance cost, so we can avoid breaking people's code. It would be good if stakeholders were to write in this bug if and when their application stops depending on toxdns, so I know when we can remove it.

I have no plans to author support for HTTP[S] name lookups in uTox.

That said, I do plan to write a name lookup API into toxcore when possible. And develop uTox concurrently with that feature. Once that is done, I plan to drop DNS name support from uTox.

@GrayHatter Why you think, that toxcore, and not a client should provide lookup feature?

I'll agree with @ovalseven8 when he says name lookups shouldn't be handled by toxcore. If he also agrees that Messenger shouldn't be handled by toxcore.

First: Messenger as an application needs to be easy to use.
And: ToxIDs aren't easy to use.
Thus: Messenger needs to make them easy.

I think simple name lookup/resolution is a familiar and useful solution.

The lookup will be vital for tox when adressing non technical people. To convince more people to use tox, especially on phones, a phone number/book -> tox id solution is required. Otherwise any in my family or any friend will switch.
And leaving that to the clients would end in desaster.
