This test would occaisonally fail with:
=== RUN TestGRPCErrorWrapping
grpc_test.go:125:
Error Trace: grpc_test.go:125
Error: Received unexpected error:
EOF
Test: TestGRPCErrorWrapping
According to the GPRC docs
(https://pkg.go.dev/google.golang.org/grpc#section-readme)
io.EOF indicates that the server closed the stream and
that "the status of the stream may be discovered using ReadMsg."
Since the test is ultimately attempting to assert that the error
from Recv() is properly wrapped in an "already exists" error, we
tolerate the io.EOF on Send() and continue to check the error from
Recv().
I've run with this change for about 150K iterations and haven't seen
a failure. Prior to this change we would get a few failures per 10K
iterations.
This adds proxy peering support. A configurable setting that allows for agents
to connect to a subset of proxies and be reachable through any proxy in the
cluster. This is achieved by creating grpc connections between each proxy
server. Client connections can then be passed between proxies to the desired
agent.
