Database Operation Logging - -Log database operations with context: - -```go -func logDatabaseOperation(ctx context.Context, operation string, table string, duration time.Duration, err error) { - logger := logging.ContextLogger(ctx, "database") - - event := logger.Info() - if err != nil { - event = logger.Error().Err(err) - } - - event. - Str("operation", operation). - Str("table", table). - Dur("duration", duration). - Msg("Database operation") -} -``` - -## Configuration Options - -### Log Levels - -The package supports standard zerolog levels: - -- **Debug**: Detailed information for debugging -- **Info**: General informational messages -- **Warn**: Warning messages for potential issues -- **Error**: Error messages for failures -- **Fatal**: Fatal errors that cause application exit - -### Debug vs Production - -```go -// Development mode (debug enabled) -logging.Initialize("my-service", true) - -// Production mode (info level and above) -logging.Initialize("my-service", false) -``` - -### Logger Configuration - -The global logger is configured with: -- **Console output**: Human-readable format for development -- **Timestamp**: RFC3339 format timestamps -- **Service name**: Consistent service identification -- **Process ID**: For multi-instance deployments -- **Caller information**: File and line number for debugging - -## Field Types and Usage - -### String Fields -```go -logger.Info(). - Str("user_id", "12345"). - Str("action", "login"). - Msg("User action") -``` - -### Numeric Fields -```go -logger.Info(). - Int("count", 42). - Int64("timestamp", time.Now().Unix()). - Float64("percentage", 95.5). - Msg("Metrics") -``` - -### Boolean Fields -```go -logger.Info(). - Bool("success", true). - Bool("cache_hit", false). - Msg("Operation result") -``` - -### Duration Fields -```go -logger.Info(). - Dur("duration", 150*time.Millisecond). - Dur("timeout", 30*time.Second). - Msg("Timing information") -``` - -### Error Fields -```go -logger.Error(). - Err(err). - Str("context", "user authentication"). - Msg("Authentication failed") -``` - -### Time Fields -```go -logger.Info(). - Time("started_at", startTime). - Time("completed_at", time.Now()). - Msg("Process timeline") -``` - -## Integration with Other Packages - -### Database Package Integration - -```go -import ( - "github.com/jasoet/pkg/db" - "github.com/jasoet/pkg/logging" -) - -func setupDatabase(ctx context.Context) (*gorm.DB, error) { - logger := logging.ContextLogger(ctx, "database-setup") - - config := &db.ConnectionConfig{ - DBType: db.Postgresql, - Host: "localhost", - // ... other config - } - - logger.Info().Str("db_type", string(config.DBType)).Msg("Connecting to database") - - database, err := config.Pool() - if err != nil { - logger.Error().Err(err).Msg("Database connection failed") - return nil, err - } - - logger.Info().Msg("Database connection successful") - return database, nil -} -``` - -### REST Package Integration - -```go -import ( - "github.com/jasoet/pkg/rest" - "github.com/jasoet/pkg/logging" -) - -func makeAPICall(ctx context.Context) { - logger := logging.ContextLogger(ctx, "api-client") - - client, err := rest.NewClient(&rest.Config{ - BaseURL: "https://api.example.com", - }) - - logger.Info().Str("base_url", "https://api.example.com").Msg("Making API call") - - // Make request with logging - response, err := client.Get("/users") - if err != nil { - logger.Error().Err(err).Msg("API call failed") - return - } - - logger.Info().Int("status", response.StatusCode).Msg("API call successful") -} -``` - -### Server Package Integration - -```go -import ( - "github.com/jasoet/pkg/server" - "github.com/jasoet/pkg/logging" -) - -func startServer(ctx context.Context) { - logger := logging.ContextLogger(ctx, "http-server") - - config := &server.Config{ - Port: 8080, - // ... other config - } - - logger.Info().Int("port", config.Port).Msg("Starting HTTP server") - - srv := server.New(config) - // Server automatically includes logging middleware -} -``` - -## Best Practices - -### 1. Initialize Once - -```go -func main() { - // Initialize logging at application startup - logging.Initialize("my-service", os.Getenv("DEBUG") == "true") - - // Rest of application... -} -``` - -### 2. Use Context Loggers - -```go -// Create component-specific loggers -func UserService(ctx context.Context) { - logger := logging.ContextLogger(ctx, "user-service") - - // Use logger throughout the component - logger.Info().Msg("User service operation") -} -``` - -### 3. Consistent Field Names - -```go -// Use consistent field names across your application -logger.Info(). - Str("user_id", userID). // Always use "user_id" - Str("request_id", requestID). // Always use "request_id" - Dur("duration", duration). // Always use "duration" - Msg("Operation completed") -``` - -### 4. Meaningful Messages - -```go -// Good: Descriptive message with context -logger.Info(). - Str("operation", "user_creation"). - Str("user_id", "12345"). - Msg("User created successfully") - -// Avoid: Generic messages without context -logger.Info().Msg("Success") -``` - -### 5. Error Context - -```go -// Provide context with errors -logger.Error(). - Err(err). - Str("function", "CreateUser"). - Str("input", userInput). - Msg("Failed to create user") -``` - -### 6. Performance Considerations - -```go -// Use conditional logging for expensive operations -if logger.Debug().Enabled() { - expensiveDebugData := generateDebugData() - logger.Debug(). - Interface("debug_data", expensiveDebugData). - Msg("Debug information") -} -``` - -## Log Analysis and Monitoring - -### JSON Output for Production - -For production environments, you might want JSON output: - -```go -// Custom logger setup for production -func setupProductionLogger(serviceName string) { - zerolog.SetGlobalLevel(zerolog.InfoLevel) - log.Logger = zerolog.New(os.Stdout). // JSON output to stdout - With(). - Timestamp(). - Str("service", serviceName). - Int("pid", os.Getpid()). - Logger() -} -``` - -### Structured Query Examples - -With structured logging, you can easily query logs: - -```bash -# Find all errors from a specific component -jq 'select(.level == "error" and .component == "database")' logs.json - -# Find slow operations -jq 'select(.duration_ms > 1000)' logs.json - -# Count requests by status code -jq -r '.status' logs.json | sort | uniq -c -``` - -## Testing with Logging - -### Test Logger Setup - -```go -func TestWithLogging(t *testing.T) { - // Setup test logger - logging.Initialize("test-service", true) - - ctx := context.Background() - logger := logging.ContextLogger(ctx, "test") - - // Your test code with logging - logger.Info().Str("test", t.Name()).Msg("Running test") -} -``` - -### Capturing Logs in Tests - -```go -func TestLogOutput(t *testing.T) { - var buf bytes.Buffer - - // Create logger that writes to buffer - testLogger := zerolog.New(&buf).With().Timestamp().Logger() - - testLogger.Info().Str("test", "example").Msg("Test message") - - // Verify log output - output := buf.String() - assert.Contains(t, output, "Test message") - assert.Contains(t, output, "test") -} -``` - -## Common Patterns - -### Request ID Tracking - -```go -func handleRequest(w http.ResponseWriter, r *http.Request) { - requestID := generateRequestID() - ctx := context.WithValue(r.Context(), "request_id", requestID) - - logger := logging.ContextLogger(ctx, "api") - logger.Info(). - Str("request_id", requestID). - Str("method", r.Method). - Str("path", r.URL.Path). - Msg("Request started") - - // Handle request... - - logger.Info(). - Str("request_id", requestID). - Msg("Request completed") -} -``` - -### Service Boundaries - -```go -func CallExternalService(ctx context.Context, serviceURL string) error { - logger := logging.ContextLogger(ctx, "external-service") - - logger.Info(). - Str("service_url", serviceURL). - Msg("Calling external service") - - start := time.Now() - - // Make call... - - logger.Info(). - Str("service_url", serviceURL). - Dur("duration", time.Since(start)). - Msg("External service call completed") - - return nil -} -``` - -## Troubleshooting - -### Common Issues - -1. **No Log Output**: Ensure `Initialize()` is called before using loggers -2. **Wrong Log Level**: Check debug parameter in `Initialize()` -3. **Missing Context**: Use `ContextLogger()` for component-specific logging -4. **Performance Impact**: Use conditional logging for expensive debug operations - -### Debug Tips - -- Use debug mode during development: `logging.Initialize("service", true)` -- Add request IDs for tracing requests across services -- Include timing information for performance analysis -- Use structured fields for easier log analysis \ No newline at end of file diff --git a/examples/logging/both/main.go b/examples/logging/both/main.go deleted file mode 100644 index 9aaf8f0..0000000 --- a/examples/logging/both/main.go +++ /dev/null @@ -1,81 +0,0 @@ -//go:build example -

Define Struct Tags +Maps prefixed environment variables onto a map-typed config section: ```go -// ✅ Good: Use both yaml and mapstructure tags -type Config struct { - Port int `yaml:"port" mapstructure:"port"` -} - -// ⚠️ May cause issues with env override -type Config struct { - Port int `yaml:"port"` // missing mapstructure -} +func WithNestedEnvVars(prefix string, keyDepth int, configPath string) Option ``` -### 2. Use Pointers for Optional Fields +- `prefix`: prefix of the environment variables to process (e.g. `"APP"`). +- `keyDepth`: **prefix-relative** — the prefix is stripped first, then `keyDepth` indexes the remaining underscore-split tokens to locate the entity name; everything after it forms the field name. +- `configPath`: base path in the configuration where values are set. ```go -// ✅ Good: Optional fields are pointers type Config struct { - Required string `yaml:"required"` - Optional *string `yaml:"optional"` -} - -// Check before using -if cfg.Optional != nil { - fmt.Println(*cfg.Optional) + Users map[string]map[string]string `yaml:"users"` } -``` - -### 3. Validate After Loading -```go -import "github.com/go-playground/validator/v10" +// APP_USERS_ADMIN_NAME: strip "APP" -> ["USERS", "ADMIN", "NAME"]; +// keyDepth 1 -> entity "admin", field "name" under path "users". +os.Setenv("APP_USERS_ADMIN_NAME", "alice") -type Config struct { - Port int `yaml:"port" validate:"required,min=1,max=65535"` - Host string `yaml:"host" validate:"required,hostname"` -} - -cfg, err := config.LoadString[Config](yamlString) -if err != nil { - return err -} - -validate := validator.New() -if err := validate.Struct(cfg); err != nil { - return fmt.Errorf("invalid config: %w", err) -} +cfg, err := config.LoadStringWithOptions[Config](``, + config.WithNestedEnvVars("APP", 1, "users"), +) +// cfg.Users["admin"]["name"] == "alice" ``` -### 4. Environment-Specific Defaults +**Precedence contract:** nested env vars fill only keys that are *absent* from the YAML. If the YAML already sets a key, the environment variable is ignored: ```go -customFn := func(v *viper.Viper) { - // Set defaults for production - if os.Getenv("APP_ENV") == "production" { - v.SetDefault("server.timeout", 30) - v.SetDefault("logging.level", "info") - } else { - v.SetDefault("server.timeout", 60) - v.SetDefault("logging.level", "debug") - } -} +os.Setenv("APP_USERS_ADMIN_NAME", "alice") +os.Setenv("APP_USERS_ADMIN_EMAIL", "alice@example.com") -cfg, _ := config.LoadStringWithConfig[AppConfig](yamlString, customFn) +cfg, _ := config.LoadStringWithOptions[Config](`users: {admin: {name: bob}}`, + config.WithNestedEnvVars("APP", 1, "users"), +) +// cfg.Users["admin"]["name"] == "bob" (YAML wins) +// cfg.Users["admin"]["email"] == "alice@example.com" (filled from env) ``` -### 5. Secrets Management +Note: unlike the flat `ENV_` override mechanism (which overrides YAML), `WithNestedEnvVars` never overrides YAML keys. -```go -// ✅ Good: Never commit secrets to YAML -yamlConfig := ` -database: - host: localhost - port: 5432 - # username and password from env vars only -` - -// Set via environment -// ENV_DATABASE_USERNAME=admin -// ENV_DATABASE_PASSWORD=secret123 +## Struct Tags -cfg, _ := config.LoadString[DatabaseConfig](yamlConfig) -``` +Decoding is case-insensitive via mapstructure, so plain `yaml` tags (as used throughout these examples) are sufficient. Adding matching `mapstructure` tags is harmless but not required. ## Testing -The package includes comprehensive tests with 94.7% coverage: - ```bash -# Run tests -go test ./config -v - -# With coverage -go test ./config -cover -``` - -### Test Utilities - -```go -func TestMyConfig(t *testing.T) { - yamlConfig := ` - name: test-app - version: 1.0.0 - ` - - // Set test env vars - t.Setenv("ENV_NAME", "test-override") - - cfg, err := config.LoadString[TestConfig](yamlConfig) - assert.NoError(t, err) - assert.Equal(t, "test-override", cfg.Name) -} -``` - -## Troubleshooting - -### Environment Variables Not Working - -**Problem**: Env vars not overriding YAML values - -**Solution**: -```go -// 1.

Managers now borrow a caller-owned client.Client — consumers who used NewWorkerManager(&cfg)/NewScheduleManager(cfg)+Close must now create AND close their own client (managers no longer close it). WorkflowManager.Close REMOVED entirely (was a no-op after ownsClient removal). Close() → Close(ctx) on WorkerManager and ScheduleManager. NewWorkflowManagerWithNamespace's namespace param is now always authoritative (previously ignored when a *Config was passed). NOTE: commit cadc208's BREAKING footer omits the WorkflowManager.Close removal — release notes must include it manually. - **Final docs sweep must cover stale db APIs** in: PROJECT_TEMPLATE.md (lines ~328,361,580,599,1196,1200,2029,2030,2100,2106), AI_PATTERN.md (~106), examples/fullstack-otel/README.md (~213). Old: cfg.Pool() and RunPostgresMigrationsWithGorm. New: db.NewPool(db.WithConnectionConfig(cfg)); gormDB.DB() + RunPostgresMigrations. - **Migration guide (db section):** metrics-only configs now emit db.client.connections.* series that previously never appeared (bug fix working, dashboards may newly fire); RedactedDsn output changes only for pathological password/DSN-substring collisions (safe direction). - **docker remaining leaks (decision needed):** `Executor.Inspect() (*container.InspectResponse, error)` (status.go:166) and `Executor.GetStats() (container.StatsResponseReader, error)` (status.go:258) still expose docker/docker types. Decide: document as escape hatch by design (like temporal/argo) or wrap in v3.x. diff --git a/examples/temporal/dashboard/README.md b/examples/temporal/dashboard/README.md index 4f94701..c773023 100644 --- a/examples/temporal/dashboard/README.md +++ b/examples/temporal/dashboard/README.md @@ -201,21 +201,27 @@ import ( "fmt" "log" - "github.com/jasoet/pkg/v2/temporal" + "github.com/jasoet/pkg/v3/temporal" ) func main() { - // Create WorkflowManager - config := &temporal.Config{ + // Create the Temporal client (caller owns it and must close it) + cfg := &temporal.Config{ HostPort: "localhost:7233", Namespace: "default", } - wm, err := temporal.NewWorkflowManager(config) + c, err := temporal.NewClient(temporal.WithConfig(*cfg)) + if err != nil { + log.Fatalf("Failed to create Temporal client: %v", err) + } + defer c.Close() + + // WorkflowManager borrows the client — it has no Close of its own + wm, err := temporal.NewWorkflowManagerWithNamespace(c, cfg.Namespace) if err != nil { log.Fatalf("Failed to create WorkflowManager: %v", err) } - defer wm.Close() ctx := context.Background() From 0a8b205186ba68e894f401224b311b431f04eb05 Mon Sep 17 00:00:00 2001 From: Jasoet Martohartono Date: Thu, 23 Jul 2026 06:31:38 +0700 Subject: [PATCH 067/103] docs(plans): add v3 phase 12 plan (argo unification) --- .../plans/2026-07-22-v3-phase12-argo.md | 153 ++++++++++++++++++ 1 file changed, 153 insertions(+) create mode 100644 docs/superpowers/plans/2026-07-22-v3-phase12-argo.md diff --git a/docs/superpowers/plans/2026-07-22-v3-phase12-argo.md b/docs/superpowers/plans/2026-07-22-v3-phase12-argo.md new file mode 100644 index 0000000..6a1f446 --- /dev/null +++ b/docs/superpowers/plans/2026-07-22-v3-phase12-argo.md @@ -0,0 +1,153 @@ +# v3 Phase 12: argo Unification + +> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task.

-```go -// ✅ Protected: These paths are blocked -"../etc/passwd" // Blocked: Contains .. -"/etc/passwd" // Blocked: Absolute path -"dir/../../../etc/pass" // Blocked: Traversal attempt -``` - -**Implementation:** -```go -// Path validation -if strings.Contains(path, "..") { - return fmt.Errorf("invalid path") -} - -// Ensure within destination -if !strings.HasPrefix(target, destinationDir) { - return fmt.Errorf("path traversal attempt") -} -``` - -### Zip Bomb Protection - -Limits decompression to prevent resource exhaustion: - -```go -// 100MB limit per file -limitedReader := io.LimitReader(reader, 100*1024*1024) -io.Copy(dest, limitedReader) -``` - -**Why:** -- Small compressed file (1KB) can expand to gigabytes -- Exhausts disk space and memory -- Causes denial of service - -**Protection:** -- Each file limited to 100MB decompressed -- Error returned if limit exceeded - -### File Mode Validation - -Sanitizes file permissions to prevent dangerous modes: - -```go -// Cap at 0o777, use safe default for invalid modes -fileMode := header.Mode -if fileMode > 0o777 { - fileMode = 0o644 // Safe default -} -safeMode := os.FileMode(fileMode & 0o777) -``` - -**Why:** -- Prevents setuid/setgid bits -- Prevents unsafe permissions -- Ensures consistent file modes - -## Advanced Usage -

Validate Destination - -```go -// ✅ Good: Check destination exists and is directory -info, err := os.Stat(destDir) -if err != nil { - return err -} -if !info.IsDir() { - return fmt.Errorf("destination must be directory") -} - -compress.UnTarGz(reader, destDir) -``` - -### 2. Handle Large Files - -```go -// ✅ Good: Stream large files -source, _ := os.Open("large-file.txt") -defer source.Close() - -dest, _ := os.Create("output.gz") -defer dest.Close() - -compress.Gz(source, dest) // Streams, low memory -``` - -### 3. Close Writers - -```go -// ✅ Good: Ensure writers are closed -outputFile, _ := os.Create("archive.tar.gz") -defer outputFile.Close() - -if err := compress.TarGz("/my/dir", outputFile); err != nil { - return err -} -// Deferred close ensures data is flushed -``` - -### 4. Check Written Bytes - -```go -// ✅ Good: Verify extraction -written, err := compress.UnTarGz(reader, "/dest") -if err != nil { - return err -} - -if written == 0 { - log.Warn("No files extracted") -} -log.Printf("Extracted %d bytes", written) -``` - -### 5. Use Base64 for APIs - -```go -// ✅ Good: Base64 for text transport -type Response struct { - Archive string `json:"archive"` -} - -encoded, _ := compress.TarGzBase64("/data") -response := Response{Archive: encoded} -json.Marshal(response) -``` +Guard-rail rejections wrap documented sentinels — match them with `errors.Is`, +never by comparing message strings: + +| Sentinel | Returned when | +| --- | --- | +| `ErrPathTraversal` | `UnGz` destination is not absolute; a tar entry path is empty, absolute, contains `..` or `\`, escapes the destination, or resolves through a symlink outside it | +| `ErrSizeLimitExceeded` | A file exceeds `maxFileSize`, or the archive total exceeds `maxArchiveSize` | +| `ErrNotDirectory` | `Tar` source or `UnTar`/`UnTarGz` destination is not a directory | + +```go +written, err := compress.UnTarGz(reader, destDir) +switch { +case errors.Is(err, compress.ErrPathTraversal): + // Malicious or malformed entry path — reject the archive. +case errors.Is(err, compress.ErrSizeLimitExceeded): + // Zip bomb protection triggered; written holds bytes extracted so far. +case errors.Is(err, compress.ErrNotDirectory): + // Fix the destination and retry. +case err != nil: + // I/O or corrupt-archive error (e.g. gzip.ErrHeader, io.ErrUnexpectedEOF). +} +``` + +Missing destinations, corrupt archives, and filesystem failures surface as the +underlying `os`/`gzip`/`tar` errors and are matchable with `errors.Is` against +`fs.ErrNotExist` and friends. + +## Security Details + +- **Path traversal prevention**: tar entry names are rejected when empty, + absolute, or containing `..` or `\`; the joined target path must stay under + the destination; parent directories are resolved with + `filepath.EvalSymlinks` to stop symlink TOCTOU escapes. +- **Zip bomb protection**: extraction streams through `io.LimitReader`; one + extra byte is probed past the limit so oversized content is detected and + reported with `ErrSizeLimitExceeded`. +- **File mode sanitization**: extracted file modes are masked with `0o777`, + stripping setuid/setgid/sticky bits; directories are created `0o750`. +- **`UnGz` vs `UnTar` path rules**: `UnGz` requires an absolute destination + path, while `UnTar` accepts a relative destination directory.

Use Typed Builders +1. **First causal error only** — secondary errors are discarded; partial results are not returned. +2. **All-or-nothing** — the result map is nil if any function errors or panics. +3. **Unordered map results** — access results by key, not iteration order. +4. **Single element type** — all functions in one call return the same `T` (use `any` plus a builder for heterogeneous results). -```go -// ✅ Good: Type-safe result building -type Result struct { - Users int - Orders int -} +## Examples -concurrent.ExecuteConcurrentlyTyped( - ctx, - func(results map[string]int) (Result, error) { - return Result{ - Users: results["users"], - Orders: results["orders"], - }, nil - }, - funcs, -) +Runnable examples live in [examples/concurrent/](../examples/concurrent/) and are +behind the `example` build tag.

error and 404 responses - derive the real status from the handler error after next() so errors and 404s are no longer recorded as 200, and set span status Error for 5xx - fractional-millisecond
