fix(cluster): preserve internal transport isolation - #495
Conversation
PR SummaryHigh Risk Overview Moves inter-node gRPC to a dedicated cluster endpoint modeled as Tightens membership and ops behavior: client cluster views drop Manager placeholders; gossip merge matches members by cluster endpoint and avoids replacing the local node with a newer cluster seed; leader resignation replies wait until gossip includes the resigning leader and go over the cluster endpoint; replication/forwarding reconnect when the cluster endpoint changes, not when only the client HTTP port moves. Configuration and transport: validates that node and replication listeners cannot bind the same address/port; replication heartbeat settings must be positive and drive HTTP/2 keepalives (sub-second values clamped to 1s); Reviewed by Cursor Bugbot for commit 26c5591.

In `@src/EventStore.ClusterNode/Components/Services/ClusterStatusService.cs`:
- Around line 171-221: Update ClientMemberInfo to preserve each member’s
ReplicationEndPoint, then modify FindMemberByEndpoint to match the cleaned
subscription endpoint against that replication endpoint as well as the existing
HTTP endpoint. Ensure isolated replication lookups resolve the correct member so
catching-up status and bytes remaining are calculated accurately.
In
`@src/EventStore.Core.Tests/Services/Replication/ReadOnlyReplica/connecting_to_read_only_replica.cs`:
- Around line 106-116: Update the delete_stream_is_rejected test setup to create
the target stream through the writable leader and wait until replication
completes before invoking DeleteAsync on the read-only replica. Keep the Any
delete request and NotFound assertion, but ensure they exercise an existing
replicated stream.
In `@src/EventStore.Core/Configuration/ClusterVNodeOptions.cs`:
- Around line 650-657: Update the Description attribute for
ReplicationTcpPortAdvertiseAs to identify it as a deprecated alias for
ReplicationPortAdvertiseAs while retaining the existing replication-port
description. Leave ReplicationPortAdvertiseAs and the Deprecated attribute
unchanged.
