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

|
**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.
