Sean Chittenden f44f411b70 Merge pull request #1712 from hashicorp/b-dns-single-record

Sean Chittenden 19721f5c3d Editorialize the comment re: UDPAnswerLimit 
Prodded by: slackpad & fusiondog
 2016-03-30 01:15:40 -07:00
Sean Chittenden 5ba7e74bb8 Use table-driven test for response limits 
Much more exhaustive testing and shows where the limits are of the 512B limitation (quering by ID is less space efficient than querying by just a prepared query or service).

Sean Chittenden 5501feecbe Rename serverConfig to serverList 
serverList is a vastly more accurate name.  Chase accordingly.  No functional change other than types and APIs.

Sean Chittenden 6185f931d8 Gratuitous rename 1/2 
Reduce cognative load and perform an overdue rename.  No functional change.

Sean Chittenden b684b15d94 Refactor out recocileServerList anon function 
Add testing to reconcileServerList and test various server sizes.

Test that a percentage of nodes fail their Ping (50% in testing atm)

Sean Chittenden c56f039884 Teach fauxConnPool to fail a pct of the time 
50% failure rate seems legit as a starting point w/ 100 servers.

Sean Chittenden 6648d31579 Add log line re: server manager backing off and sleeping 
This is useful in situations where the RPC rotate duration is greater than 1µs.  WTB exponential backoff of logging so we don't spam forever.

Sean Chittenden 4589c36308 Switch the order of ServerDetails.String() 
It's more natrual to have the network first.  I think I flipped the order accidentally.
