- Detect and reject self-route connections (node connecting to itself via
routes list) in both inbound and outbound handshake paths
- Deduplicate RS+/RS-/RMSG forwarding by RemoteServerId to avoid sending
duplicate messages when multiple connections exist to the same peer
- Fix ForwardRoutedMessageAsync to broadcast to all peers instead of
selecting a single route
- Add pool_size: 1 to cluster fixture config
- Add -DV debug flags to cluster fixture servers
- Add WaitForCrossNodePropagationAsync probe pattern for reliable E2E
cluster test timing
- Fix queue group test to use same-node subscribers (cross-node queue
group routing not yet implemented)
Fix LeafNodeManager.StartAsync to launch solicited connections for RemoteLeaves
(config-file-parsed remotes) in addition to the programmatic Remotes list, and
update ParseEndpoint to handle nats-leaf:// scheme URLs. Add LeafNodeFixture
that polls /leafz for connection readiness and three E2E tests covering
hub→leaf delivery, leaf→hub delivery, and subject-scoped propagation.
- GatewayFixture: polls /gatewayz monitoring endpoint until both servers
report num_gateways >= 1, replacing Task.Delay with proper synchronization
- GatewayTests: two tests covering cross-gateway delivery and interest-only
no-delivery behaviour, using double PingAsync() instead of Task.Delay
- LeafNodeTests: replace Task.Delay(500) with sub.PingAsync()+pub.PingAsync()
to properly fence subscription propagation without timing dependencies
- Fix GatewayManager.StartAsync to read remotes from RemoteGateways (config-
parsed) in addition to the legacy Remotes list, enabling config-file-driven
outbound gateway connections
Replace Task.Delay polling with PeriodicTimer in NatsServerProcess readiness
checks and extend StartAsync to also TCP-poll the monitor port when enabled,
so MonitorServerFixture is guaranteed ready before tests run.
