Gateway Connection Lifecycle Management

Module

Gateway

Status

VERIFIED

Description

HELLO frame processing for microservice registration, connection lifecycle management with cleanup on disconnect, and ConnectionManager hosted service for monitoring active connections.

Implementation Details

  • Gateway hosted service: src/Gateway/StellaOps.Gateway.WebService/Services/GatewayHostedService.cs -- connection lifecycle management background service (533 lines)
  • Health monitoring: src/Gateway/StellaOps.Gateway.WebService/Services/GatewayHealthMonitorService.cs -- monitors active connections, detects stale instances (107 lines)
  • Metrics: src/Gateway/StellaOps.Gateway.WebService/Services/GatewayMetrics.cs -- connection metrics tracking (40 lines)
  • Configuration: src/Gateway/StellaOps.Gateway.WebService/Configuration/GatewayOptions.cs, GatewayOptionsValidator.cs
  • Source: batch_51/file_22.md

E2E Test Plan

  • Verify HELLO frame processing registers new microservice connections
  • Test connection cleanup on client disconnect
  • Verify GatewayHealthMonitorService detects stale connections
  • Verify edge cases and error handling

Verification

  • Run ID: run-002
  • Date: 2026-02-09
  • Method: Tier 1 code review + Tier 2d integration tests
  • Build: PASS (0 errors, 0 warnings)
  • Tests: PASS (202/202 gateway tests pass)
  • Code Review:
    • GatewayHostedService: Non-trivial (533 lines). HandleHelloAsync() parses/validates HELLO payloads, builds connection state, registers in routing state. HandleDisconnect() removes connections, invalidates caches, cleans claims.
    • GatewayHealthMonitorService: Real BackgroundService checking stale/degraded connections based on configurable thresholds.
    • Tests: Config/integration tests exist (GatewayOptionsValidatorTests, GatewayIntegrationTests). Caveat: no dedicated unit tests for HELLO frame validation or heartbeat handling logic paths.
  • Verdict: PASS
