# Phase 6 Implementation Guide
|
||||
|
||||
This technical guide provides detailed implementation specifications for the Phase 6 Plugin System. It includes code snippets, architectural decisions, and implementation details for developers who will be implementing the code.
|
||||
|
||||
## Directory Structure
|
||||
|
||||
Create the following directory structure for the plugin system:
|
||||
|
||||
```text
|
||||
libs/network/src/
|
||||
├── plugins/
|
||||
│ ├── types.ts # Core plugin interfaces and types
|
||||
│ ├── plugin-manager.ts # Main plugin system entry point
|
||||

|
||||

|
||||
└── phase6-integration.ts # Integration with Phase 5 components
|
||||
```
|
||||
|
||||
## Core Interfaces and Types
|
||||
|
||||
The `types.ts` file will define these key interfaces:
|
||||
|
||||
1. **IPlugin Interface**: The core interface that all plugins must implement
|
||||
- Properties: id, version, displayName, description, author, homepage
|
||||
- Methods: onRegister, onUnregister, initialize, shutdown, configure, getCapabilities, getExtensions
|
||||
|
||||
2. **PluginContext Interface**: The context provided to each plugin
|
||||
- Access to other plugins, event system, extension points, resource monitoring
|
||||
- Controlled environment for plugin execution
|
||||
|
||||
3. **ExtensionPoint Interface**: Defines extension points where plugins can provide functionality
|
||||
- Methods for getting, adding, and removing extensions
|
||||
- Schema validation for extensions
|
||||
|
||||
4. **Plugin Lifecycle States**: Enum defining the plugin states
|
||||
- REGISTERED, INITIALIZING, ACTIVE, INACTIVE, ERROR, UNREGISTERED
|
||||
|
||||
## Plugin Manager
|
||||
|
||||
The Plugin Manager is the main entry point for the plugin system and should implement:
|
||||
|
||||
1. **Registration/Unregistration**: Methods for registering and unregistering plugins
|
||||
2. **Lifecycle Management**: Initialize and shutdown plugins in the correct order
|
||||
3. **Plugin Access**: Get plugin by ID or query by type
|
||||
4. **Extension Point Management**: Create and access extension points
|
||||
5. **Event System**: Plugin lifecycle events and cross-plugin communication
|
||||
|
||||
Security considerations:
|
||||
|
||||
- Validate plugins during registration
|
||||
- Control plugin capabilities and access
|
||||
- Isolate plugins from each other
|
||||
|
||||
## Plugin Registry
|
||||
|
||||
The Plugin Registry maintains information about registered plugins:
|
||||
|
||||
1. **Plugin Storage**: Store plugin instances and metadata
|
||||
2. **Plugin State Tracking**: Track the current state of each plugin
|
||||
3. **Dependency Resolution**: Determine plugin load order based on dependencies
|
||||
4. **Version Compatibility**: Check version constraints between plugins
|
||||
|
||||
Implementation details:
|
||||
|
||||
- Use a Map to store plugins by ID
|
||||
- Implement topological sorting for dependency-based ordering
|
||||
- Track registration time and plugin state
|
||||
|
||||
## Extension Point System
|
||||
|
||||
The Extension Point system enables plugins to extend functionality at defined points:
|
||||
|
||||
1. **Extension Point Registration**: Create new extension points with schemas
|
||||
2. **Extension Management**: Add, remove, and query extensions
|
||||
3. **Schema Validation**: Validate extensions against their schemas
|
||||
4. **Extension Ordering**: Support priority-based ordering of extensions
|
||||
|
||||
Implementation details:
|
||||
|
||||
- Use a registry of extension points
|
||||
- Implement schema validation for extensions
|
||||
- Provide filtering and ordering capabilities
|
||||
|
||||
## Resource Monitoring
|
||||
|
||||
The Resource Monitor tracks and controls plugin resource usage:
|
||||
|
||||
1. **Resource Tracking**: Monitor CPU, memory, network, and storage usage
|
||||
2. **Resource Limiting**: Apply limits to plugin resource consumption
|
||||
3. **Usage Reporting**: Provide resource usage reports
|
||||
4. **Throttling**: Automatically throttle high-usage plugins
|
||||
|
||||
Implementation details:
|
||||
|
||||
- Use TimerController for periodic monitoring
|
||||
- Track resource usage history
|
||||
- Implement configurable thresholds and actions
|
||||
|
||||

||||
Implement these core plugins:
|
||||
|
||||

## Integration with Phase 5
|
||||
|
||||
### Enhancing the Tier Manager
|
||||
|
||||
Enhance the EnhancedTierManager to support plugins:
|
||||
|
||||
1. **Extension Points**: Add extension points for tier strategies
|
||||
2. **Plugin Discovery**: Find and integrate relevant plugins
|
||||
3. **Strategy Selection**: Choose optimal strategies from plugins
|
||||
4. **Fallback Mechanisms**: Use built-in logic when no plugins are available
|
||||
|
||||
Implementation details:
|
||||
|
||||
- Extend EnhancedTierManager with plugin support
|
||||
- Integrate with ResourceBalancer and TierPartitionHandler
|
||||
- Create plugin-aware optimizers
|
||||
|
||||
### Resource Balancer Integration
|
||||
|
||||
Enhance the ResourceBalancer to work with the ResourceManagementPlugin:
|
||||
|
||||
1. **Resource Metrics**: Use plugin-provided metrics
|
||||
2. **Optimization Strategies**: Apply plugin-suggested optimizations
|
||||
3. **Threshold Handling**: Respond to plugin-detected threshold crossings
|
||||
|

2. **Recovery Testing**: Simulate partition healing
|
||||
3. **Resilience Verification**: Verify partition detection and handling
|
||||
|
||||
## Testing Approach
|
||||
|
||||
Use these strategies for testing:
|
||||
|
||||
1. **Real Simulation Over Mocking**: Use MemoryTransport instead of mocks
|
||||
2. **Time Control**: Use TimerController instead of Jest timers
|
||||
3. **Isolation**: Create isolated test instances of PluginManager
|
||||
4. **Security**: Test plugin security boundaries
|
||||
5. **Resource Testing**: Verify resource monitoring and limits
|
||||
|
||||
Test structure:
|
||||
|
||||
- Unit tests for individual components
|
||||
- Integration tests for plugin interactions
|
||||
- Security tests for plugin isolation
|
||||
- Performance tests for overhead measurement
|
||||
|
||||
