Daniel Nephin	1a137c29d6	grpc: fix grpc metrics ... defaultMetrics was being set at package import time, which meant that it received an instance of the original default. But lib/telemetry.InitTelemetry sets a new global when it is called. This resulted in the metrics being sent nowhere. This commit changes defaultMetrics to be a function, so it will return the global instance when called. Since it is called after InitTelemetry it will return the correct metrics instance.	4 years ago
Daniel Nephin	8a785a351c	agent/grpc: pass metrics to constructor ... Instead of referencing a package var. This does not fix the flaky test, but it seems more correct.	4 years ago
Daniel Nephin	19da9c3a9b	agent/grpc: use a separate channel for closing the Accept ... Closing l.conns can lead to a race and a 'panic: send on closed chan' when a connection is in the middle of being handled when the server is shutting down. Found using '-race -count=800'	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	2273673500	grpc: restore integration tests for grpc client conn pool ... Add a fake rpc Listener	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
