*models.QueuedTask) uint64 { /* ... */ } +func (m *MyPlugin) GetPoolCount() uint64 { /* ... */ } +``` + +### Step 2: Register the Plugin in init() + +```go +func init() { + plugin.RegisterNewPlugin("myplugin", func(config *plugin.SchedConfig) (plugin.CustomScheduler, error) { + // Create and configure your plugin + myPlugin := NewMyPlugin(config) + + // Apply any additional configuration + if config.SliceNsDefault > 0 { + myPlugin.SetSliceDefault(config.SliceNsDefault) + } + + return myPlugin, nil + }) +} +``` + +### Step 3: Use Your Plugin + +```go +import _ "github.com/yourorg/myplugin" // Import to trigger init() + +config := &plugin.SchedConfig{ + Mode: "myplugin", + SliceNsDefault: 5000000, +} + +scheduler, err := plugin.NewSchedulerPlugin(config)

configuration requirements + +## Migration from Previous Implementation + +### Before (Hardcoded in Gthulhu) + +```go +// In Gthulhu main.go +switch schedConfig.Mode { +case "gthulhu": + plugin =

This eliminates the need for switch-case statements in the Gthulhu main repository and allows new plugins to be added without modifying existing code. - -## Key Components - -### 1. SchedConfig Structure - -The `SchedConfig` struct holds all configuration parameters needed to create a plugin: - -```go -type SchedConfig struct { - // Mode specifies which scheduler plugin to use (e.g., "gthulhu", "simple", "simple-fifo") - Mode string - - // SimpleScheduler configuration - SliceNsDefault uint64 - SliceNsMin uint64 - FifoMode bool - - // Scheduler configuration (for Gthulhu plugin) - Scheduler struct { - SliceNsDefault uint64 - SliceNsMin uint64 - } - - // API configuration - APIConfig struct { - PublicKeyPath string - BaseURL string - } -} -``` - -### 2. Plugin Registration API - -The `RegisterNewPlugin` function allows plugins to register themselves during initialization: - -```go -func RegisterNewPlugin(mode string, factory PluginFactory) error -``` - -- **mode**: Unique identifier for the plugin (e.g., "gthulhu", "simple") -- **factory**: Function that creates an instance of the plugin -- **Returns**: Error if mode is empty, factory is nil, or mode is already registered - -### 3. Factory Function - -The `NewSchedulerPlugin` function creates plugin instances based on configuration: - -```go -func NewSchedulerPlugin(config *SchedConfig) (CustomScheduler, error) -``` - -- **config**: Configuration specifying which plugin to create and its parameters -- **Returns**: CustomScheduler instance or error if mode is unknown - -## Usage Examples - -### Creating a Plugin Instance - -```go -import "github.com/Gthulhu/plugin/plugin" - -// Create a Gthulhu plugin -config := &plugin.SchedConfig{ - Mode: "gthulhu", - SliceNsDefault: 5000 * 1000, // 5ms - SliceNsMin: 500 * 1000, // 0.5ms -} - -scheduler, err := plugin.NewSchedulerPlugin(config) -if err != nil { - log.Fatalf("Failed to create plugin: %v", err) -} - -// Use the scheduler -scheduler.DrainQueuedTask(sched) -``` - -### Creating Different Plugin Types - -```go -// Create a simple plugin with weighted vtime -simpleConfig := &plugin.SchedConfig{ - Mode: "simple", - SliceNsDefault: 500000, -} -simpleScheduler, _ := plugin.NewSchedulerPlugin(simpleConfig) - -// Create a simple plugin with FIFO mode -fifoConfig := &plugin.SchedConfig{ - Mode: "simple-fifo", -} -fifoScheduler, _ := plugin.NewSchedulerPlugin(fifoConfig) -``` - -### Using API Configuration - -```go -// Create a Gthulhu plugin with API authentication -config := &plugin.SchedConfig{ - Mode: "gthulhu", -} -config.Scheduler.SliceNsDefault = 10000 * 1000 -config.Scheduler.SliceNsMin = 1000 * 1000 -config.APIConfig.PublicKeyPath = "/path/to/public.key" -config.APIConfig.BaseURL = "https://api.example.com" - -scheduler, err := plugin.NewSchedulerPlugin(config) -if err != nil { - log.Fatalf("Failed to create plugin: %v", err) -} -``` - -## Implementing a New Plugin - -To create a new plugin that integrates with the factory pattern: - -### Step 1: Implement the CustomScheduler Interface - -```go -package myplugin - -import ( - "github.com/Gthulhu/plugin/models" - "github.com/Gthulhu/plugin/plugin" -) - -type MyPlugin struct { - // Your plugin fields -} - -func NewMyPlugin(config *plugin.SchedConfig) *MyPlugin { - return &MyPlugin{ - // Initialize based on config - } -} - -// Implement CustomScheduler interface methods -func (m *MyPlugin) DrainQueuedTask(s plugin.Sched) int { /* ... */ } -func (m *MyPlugin) SelectQueuedTask(s plugin.Sched) *models.QueuedTask { /* ... */ } -func (m *MyPlugin) SelectCPU(s plugin.Sched, t *models.QueuedTask) (error, int32) { /* ... */ } -func (m *MyPlugin) DetermineTimeSlice(s plugin.Sched, t *models.QueuedTask) uint64 { /* ... */ } -func (m *MyPlugin) GetPoolCount() uint64 { /* ... */ } -``` - -### Step 2: Register the Plugin in init() - -```go -func init() { - plugin.RegisterNewPlugin("myplugin", func(config *plugin.SchedConfig) (plugin.CustomScheduler, error) { - // Create and configure your plugin - myPlugin := NewMyPlugin(config) - - // Apply any additional configuration - if config.SliceNsDefault > 0 { - myPlugin.SetSliceDefault(config.SliceNsDefault) - } - - return myPlugin, nil - }) -} -``` - -### Step 3: Use Your Plugin - -```go -import _ "github.com/yourorg/myplugin" // Import to trigger init() - -config := &plugin.SchedConfig{ - Mode: "myplugin", - SliceNsDefault: 5000000, -} - -scheduler, err := plugin.NewSchedulerPlugin(config) -``` - -## Registered Plugins - -The following plugins are registered by default: - -| Mode | Description | Configuration | -|------|-------------|---------------| -| `gthulhu` | Advanced scheduler with API integration | Scheduler.SliceNsDefault, Scheduler.SliceNsMin, APIConfig | -| `simple` | Simple weighted vtime scheduler | SliceNsDefault | -| `simple-fifo` | Simple FIFO scheduler | SliceNsDefault | - -### Checking Registered Modes - -You can retrieve all registered plugin modes: - -```go -modes := plugin.GetRegisteredModes() -fmt.Printf("Available plugins: %v\n", modes) -``` - -## Benefits - -1. **Extensibility**: New plugins can be added without modifying existing code -2. **Decoupling**: Plugin implementation is separate from instantiation logic -3. **Type Safety**: Factory functions are type-safe and validated at registration -4. **Thread Safety**: Registration uses mutex protection for concurrent safety -5. **Flexibility**: Each plugin can define its own configuration requirements - -## Migration from Previous Implementation - -### Before (Hardcoded in Gthulhu) - -```go -// In Gthulhu main.go -switch schedConfig.Mode { -case "gthulhu": - plugin = gthulhu.NewGthulhuPlugin(cfg.SimpleScheduler.SliceNsDefault, cfg.SimpleScheduler.SliceNsMin) -case "simple": - plugin = simple.NewSimplePlugin(false) -case "simple-fifo": - plugin = simple.NewSimplePlugin(true) -default: - log.Fatalf("Unknown mode: %s", schedConfig.Mode) -} -``` - -### After (Using Factory Pattern) - -```go -// In Gthulhu main.go -config := &plugin.SchedConfig{ - Mode: schedConfig.Mode, - SliceNsDefault: cfg.SimpleScheduler.SliceNsDefault, - SliceNsMin: cfg.SimpleScheduler.SliceNsMin, -} -config.Scheduler.SliceNsDefault = cfg.Scheduler.SliceNsDefault -config.Scheduler.SliceNsMin = cfg.Scheduler.SliceNsMin -config.APIConfig.PublicKeyPath = cfg.API.PublicKeyPath -config.APIConfig.BaseURL = cfg.API.BaseURL - -plugin, err := plugin.NewSchedulerPlugin(config) -if err != nil { - log.Fatalf("Failed to create plugin: %v", err) -} -``` - -## Testing - -The factory pattern implementation includes comprehensive tests: - -- **Unit Tests**: Test registration, factory creation, and error handling -- **Integration Tests**: Test actual plugin creation through the factory -- **Coverage**: 100% coverage for factory pattern code - -Run tests: - -```bash -# Test plugin package (factory pattern) -go test ./plugin -v -cover - -# Test integration -go test ./tests -v - -# Overall coverage -go test ./... -coverprofile=coverage.out -go tool cover -func=coverage.out -``` - -## Error Handling - -The factory pattern provides clear error messages: - -```go -// Empty mode -err := plugin.RegisterNewPlugin("", factory) -// Error: "plugin mode cannot be empty" - -// Nil factory -err := plugin.RegisterNewPlugin("mode", nil) -// Error: "plugin factory cannot be nil" - -// Duplicate registration -err := plugin.RegisterNewPlugin("existing", factory) -// Error: "plugin mode 'existing' is already registered" - -// Unknown mode -scheduler, err := plugin.NewSchedulerPlugin(&plugin.SchedConfig{Mode: "unknown"}) -// Error: "unknown plugin mode: unknown" - -// Nil config -scheduler, err := plugin.NewSchedulerPlugin(nil) -// Error: "config cannot be nil" -``` - -## Best Practices - -1. **Register in init()**: Always register plugins in the init() function to ensure they're available before use -2. **Validate Configuration**: Factory functions should validate configuration parameters -3. **Handle Errors**: Always check for errors when creating plugins -4. **Document Modes**: Document available modes and their configuration requirements -5. **Test Registration**: Include tests that verify plugin registration and creation - -## Thread Safety - -The plugin registry is protected by a `sync.RWMutex`: - -- **Registration** (`RegisterNewPlugin`): Uses write lock -- **Factory Creation** (`NewSchedulerPlugin`): Uses read lock -- **Getting Modes** (`GetRegisteredModes`): Uses read lock -
