Fixes #4421: General solution to stop blocking queries with index 0 (#4437) 
* Fix theoretical cache collision bug if/when we use more cache types with same result type

* Generalized fix for blocking query handling when state store methods return zero index

* Refactor test retry to only affect CI

* Undo make file merge

* Add hint to error message returned to end-user requests if Connect is not enabled when they try to request cert

* Explicit error for Roots endpoint if connect is disabled

* Fix tests that were asserting old behaviour

Paul Banks 2e223ea2b7 Fix hot loop in cache for RPC returning zero index. 2018-06-25 12:25:37 -07:00
Paul Banks 43b48bc06b Get agent cache tests passing without global hit count (which is racy). 
Few other fixes in here just to get a clean run locally - they are all also fixed in other PRs but shouldn't conflict.

This should be robust to timing between goroutines now.

Mitchell Hashimoto 45e49f31de agent/cache: change behavior to return error rather than retry 
The cache behavior should not be to mask errors and retry. Instead, it
should aim to return errors as quickly as possible. We do that here.
