At the moment libevent evdns module doesn't support TCP transport. Such functionality might be useful in case dns responses are rather big and their sizes exceed the DNS protocol's original 512-byte limit.
At the moment we are working on implementing TCP transport in evdns. And we will be pleased if such functionality was added to the upstream repository.
So my question is about current plans on evdns module evolution.
Is evdns module functionality is somehow frozen or open for extending? Will our possible future patches with implementation of TCP transport for evdns be welcomed?
