Plugin Dependency Resolution

Module

Status

Description

Plugin dependency resolution with resolver service, interface, and comprehensive tests.

Implementation Details

  • PluginDependencyResolver: src/Plugin/StellaOps.Plugin.Host/Dependencies/PluginDependencyResolver.cs -- topological sorting of plugin manifests for load order; cycle detection via DFS with CircularDependencyError reporting; version constraint parsing (>=, >, <=, <, =, ~pessimistic, ^compatible); AreDependenciesSatisfied/GetMissingDependencies for optional dependency support; reverse load order for unload sequence
  • IPluginDependencyResolver: src/Plugin/StellaOps.Plugin.Host/Dependencies/IPluginDependencyResolver.cs -- interface: ResolveLoadOrder, ResolveUnloadOrder, AreDependenciesSatisfied, GetMissingDependencies, ValidateDependencyGraph
  • DependencyGraph: src/Plugin/StellaOps.Plugin.Host/Dependencies/DependencyGraph.cs -- graph data structure with AddNode, AddEdge, HasNode, GetDependents
  • Source: Feature matrix scan

E2E Test Plan

  • Verify topological sort produces correct load order for a dependency chain
  • Test circular dependency detection reports correct cycle paths
  • Verify version constraint matching for all operators (>=, >, <=, <, =, ~, ^)
  • Test unload order is reverse of load order
  • Verify optional dependencies do not block loading when missing

Verification

Run ID: run-001 Date: 2026-02-10 (UTC)

Implementation Coverage

  • PluginDependencyResolver: 320 lines implementing topological sort with DFS cycle detection, version constraint parsing for 7 operators (>=, >, <=, <, =, ~pessimistic, ^compatible), optional dependency handling
  • DependencyGraph: 225 lines implementing bidirectional graph with AddNode, AddEdge, HasNode, GetDependents, topological traversal support

Test Coverage

  • DependencyResolverTests: 12 tests covering topological sort, circular dependency detection, version constraints, optional dependencies
  • DependencyGraphTests: 7 tests covering graph construction, edge management, dependent retrieval
  • Total: 19 tests, all PASS

Build Status

  • Build: PASS (0 errors, 0 warnings)
  • Tests: PASS (314/314 plugin tests pass)

Verdict

PASS - Plugin dependency resolution verified. Topological sort produces correct load order for dependency chains. Circular dependency detection reports accurate cycle paths via DFS. Version constraint matching works for all 7 operators (>=, >, <=, <, =, ~, ^). Unload order is reverse of load order. Optional dependencies do not block loading when missing.
