Relational Call-Graph PostgreSQL Schema

Module

Signals

Status

IMPLEMENTED

Description

PostgreSQL migration scripts define relational tables for call-graph data storage.

Implementation Details

  • Modules: src/Signals/__Libraries/StellaOps.Signals.Persistence/
  • Key Classes:
    • SignalsDbContext (src/Signals/__Libraries/StellaOps.Signals.Persistence/EfCore/Context/SignalsDbContext.cs) - EF Core database context for Signals persistence
  • Migrations:
    • 001_initial_schema.sql (src/Signals/__Libraries/StellaOps.Signals.Persistence/Migrations/001_initial_schema.sql) - initial schema with call-graph tables
    • 002_runtime_agent_schema.sql (src/Signals/__Libraries/StellaOps.Signals.Persistence/Migrations/002_runtime_agent_schema.sql) - runtime agent tables
    • V3102_001__callgraph_relational_tables.sql (archived) - call-graph relational table definitions (func_nodes, call_edges, cve_func_hits)
  • Models: FuncNodeDocument, CallEdgeDocument, CveFuncHitDocument (src/Signals/StellaOps.Signals/Models/ReachabilityStore/)
  • Source: Feature matrix scan

E2E Test Plan

  • Run migration scripts and verify all call-graph tables are created (func_nodes, call_edges, cve_func_hits)
  • Insert call-graph data via SignalsDbContext and verify round-trip persistence
  • Verify relational integrity: insert edges referencing func_nodes and confirm foreign key constraints
  • Query call paths using relational joins and verify correct path reconstruction
  • Verify index performance: query by CVE ID and confirm results return within acceptable latency
