Handle cancellation + p.addError(ctx.Err()) + break + } + } + p.wg.Wait() + return p.errs +} +``` + +### Pattern 2: Hub Pattern (WebSocket) +```go +type Hub struct { + clients map[*Client]bool + clientsByID map[string]*Client + broadcast chan Message + register chan *Client + unregister chan *Client + mu sync.RWMutex // Protects maps +} + +func (h *Hub) Run() { + for { + select { + case client := <-h.register: + h.mu.Lock() + h.clients[client] = true + h.clientsByID[client.id] = client + h.mu.Unlock() + + case client := <-h.unregister: + h.mu.Lock() + delete(h.clients, client) + delete(h.clientsByID, client.id) + h.mu.Unlock() + + case message := <-h.broadcast: + h.broadcastToClients(message) + } + } +} +``` + +### Pattern 3: Read/Write Pumps +```go +// Read from WebSocket (blocking) +func (c *Client) readPump() { + defer c.hub.Unregister(c) + + for { + var message Message + if err := c.conn.ReadJSON(&message); err != nil { + break // Exit on any read error + } + + if err := c.router.Handle(c, message); err != nil { + log.Printf("handle error client=%s event=%s err=%v", c.id, message.Event, err) + } + } +} + +// Write to WebSocket (non-blocking) +func (c *Client) writePump() { + ticker := time.NewTicker(pingPeriod) + defer ticker.Stop() + + for { + select { + case message, ok := <-c.send: + if !ok { + return // Channel closed + } + if err := c.conn.WriteJSON(message); err != nil { + return // Exit on write error + } + + case <-ticker.C: + // Send periodic ping + if err := c.conn.WriteMessage(fiberws.PingMessage, nil); err != nil { + return + } + } + } +} +``` + +### Pattern 4: Sync.Once for Cleanup +```go +type Client struct { + closeOnce sync.Once + done chan struct{} + send chan Message +} + +func (c *Client) Close() { + c.closeOnce.Do(func() { + close(c.done) + close(c.send) + if err := c.conn.Close(); err != nil { + log.Printf("close error client=%s err=%v", c.id, err) + } + }) +} +``` + +**Best Practices:** +- Always use `sync.WaitGroup` to wait for goroutines +- Always use `sync.Mutex` or `sync.RWMutex` for shared state +- Always handle `ctx.Done()` for cancellation +- Use buffered channels for high-throughput scenarios +- Use `sync.Once` for one-time initialization/cleanup + +--- + +## Logging Style + +### Structured Logging with Context +```go +// Include relevant context (client ID, event, target, etc.) +log.Printf("websocket read error client=%s err=%v", c.id, err) +log.Printf("websocket handle error client=%s event=%s err=%v", c.id, message.Event, err) +log.Printf("scan started target=%s timing=%s", target, timing) +log.Printf("scan completed target=%s hosts=%d duration=%s", target, len(hosts), duration) +``` + +### Log Levels (stdlib log package) +```go +log.Printf("info: server listening on %s", addr) // Info +log.Printf("warn: scan timeout target=%s", target) // Warning +log.Printf("error: database query failed: %v", err) // Error +log.Fatalf("fatal: server init failed: %v", err) // Fatal (main only) +``` + +**Format:** +- Use `%v` for errors and complex types +- Use `%s` for strings +- Use `%d` for integers +- Use key=value pairs for structured data +- Always include error variable name: `err=%v` + +--- + +## HTTP Handler Patterns (Fiber v2) + +### Basic Handler +```go +func handleHealth(c *fiber.Ctx) error { + return c.JSON(fiber.Map{ + "status": "ok", + "version": version, + }) +} +``` + +### Handler with Request Body +```go +type ScanRequest struct { + Target string `json:"target" validate:"required"` + Timing string `json:"timing" validate:"required"` +} + +func handleScan(c *fiber.Ctx) error { + var req ScanRequest + if err := c.BodyParser(&req); err != nil { + return fiber.NewError(fiber.StatusBadRequest, "invalid request body") + } + + // Process request... + return c.JSON(fiber.Map{"scan_id": scanID}) +} +``` + +### Handler with Path Parameters +```go +func handleGetScan(c *fiber.Ctx) error { + scanID := c.Params("id") + + scan, err := getScan(scanID) + if err != nil { + return fiber.NewError(fiber.StatusNotFound, "scan not found") + } + + return c.JSON(scan) +} +``` + +### Error Response +```go +func handleError(c *fiber.Ctx, err error) error { + code := fiber.StatusInternalServerError + message := "internal server error" + + if fiberErr, ok := err.(*fiber.Error); ok { + code = fiberErr.Code + message = fiberErr.Message + } + + return c.Status(code).JSON(fiber.Map{ + "error": message, + }) +} +``` + +--- + +## Testing Guidelines + +### Test File Naming +- **Unit tests**: `scanner_test.go` (same package) +- **Integration tests**: `integration_test.go` (separate package) +- **Benchmarks**: `scanner_bench_test.go` + +### Test Function Naming +```go +func TestNmapScanner_QuickScan(t *testing.T) // Unit test +func TestNmapScanner_QuickScan_EmptyTarget(t *testing.T) // Edge case +func BenchmarkNmapScanner_QuickScan(b *testing.B) // Benchmark +``` + +### Table-Driven Tests +```go +func TestEstimateHostCount(t *testing.T) { + tests := []struct { + name string + target string + want int + }{ + {"single IP", "192.168.1.1", 1}, + {"CIDR /24", "192.168.1.0/24", 256}, + {"CIDR /16", "10.0.0.0/16", 65536}, + } + + for _, tt := range tests { + t.Run(tt.name, func(t *testing.T) { + got := estimateHostCount(tt.target) + if got != tt.want { + t.Errorf("estimateHostCount(%s) = %d, want %d", tt.target, got, tt.want) + } + }) + } +} +``` + +### Mocking +```go +type mockScanner struct { + hosts []models.Host + err error +} + +func (m *mockScanner) Scan(ctx context.Context, target string) ([]models.Host, error) { + return m.hosts, m.err +} +``` + +--- + +## Project Structure + +``` +go-nmapui/ +├── cmd/ +│ └── nmapui/ +│ └── main.go # Entry point only (initialize, run, cleanup)
