Trustin Lee a517cce92f Do not send duplicate DNS queries when the same query is in progress already ... Related issue: #5179 Motivation: When you attempt to make a lot of connection attempts to the same target host at the same time and our DNS resolver does not have a record for it in the cache, the DNS resolver will send as many DNS queries as the number of connection attempts. As a result, DNS server will reject or drop the requests, making the name resolution attempt fail. Modifications: - Add InflightNameResolver that keeps the list of name resolution queries and subscribes to the future of the matching query instead of sending a duplicate query. Result: - The AddressResolvers created by DnsAddressResolverGroup do not send duplicate DNS queries anymore		2016-05-17 15:07:36 +02:00
