Daniel Nephin	af8a617797	grpc: fix data rate in stats handler test	4 years ago
Daniel Nephin	d0256a0c07	subscribe: add a stateless subscribe service for the gRPC server ... With a Backend that provides access to the necessary dependencies.	4 years ago
Daniel Nephin	f14145e6d9	agent/grpc: always close the conn when dialing fails.	4 years ago
Daniel Nephin	e6ffd987a3	agent/grpc: seed the rand for shuffling servers	4 years ago
Daniel Nephin	2294793357	agent/grpc: use router.Manager to handle the rebalance ... The router.Manager is already rebalancing servers for other connection pools, so it can call into our resolver to do the same. This change allows us to remove the serf dependency from resolverBuilder, and remove Datacenter from the config. Also revert the change to refreshServerRebalanceTimer	4 years ago
Daniel Nephin	2273673500	grpc: restore integration tests for grpc client conn pool ... Add a fake rpc Listener	4 years ago
Daniel Nephin	bad4d3ff7c	grpc: redeuce dependencies, unexport, and add godoc ... Rename GRPCClient to ClientConnPool. This type appears to be more of a conn pool than a client. The clients receive the connections from this pool. Reduce some dependencies by adjusting the interface baoundaries. Remove the need to create a second slice of Servers, just to pick one and throw the rest away. Unexport serverResolver, it is not used outside the package. Use a RWMutex for ServerResolverBuilder, some locking is read-only. Add more godoc.	4 years ago
Daniel Nephin	25f47b46e1	grpc: move client conn pool to grpc package	4 years ago
Daniel Nephin	636f76f6f1	agent/grpc: make TestHandler_EmitsStats predictable ... Occasionally this test would flake. The flakes were fixed by: 1. Stopping the service and retrying to check on metrics. This way we also include the active_streams going to 0 in the metric calls. 2. Using a reference to the global Metrics. This way when other tests have background goroutines that are still shutting down, they won't emit metrics to the metric instance with the fake Sink. The stats test can patch the local reference to the global, so the existing statHandlers will continue to emit to the global, but the stats test will send all metrics to the replacement.	4 years ago
Daniel Nephin	ee65ee541e	grpc: add Datacenter field to testing service response	4 years ago
Daniel Nephin	fd42804063	grpc: Add a simple test service for testing the gRPC server	4 years ago
Daniel Nephin	2257247095	server: add gRPC server for streaming events ... Includes a stats handler and stream interceptor for grpc metrics. Co-authored-by: Paul Banks <banks@banksco.de>	4 years ago
