🗄️ IMPLEMENT FILER SESSION STORE: Production-Ready Persistent Session Storage!
MAJOR ENHANCEMENT: Complete FilerSessionStore for Enterprise Deployments 🏆 PRODUCTION-READY FILER INTEGRATION: - Full SeaweedFS filer client integration using pb.WithGrpcFilerClient - Configurable filer address and base path for session storage - JSON serialization/deserialization of session data - Automatic session directory creation and management - Graceful error handling with proper SeaweedFS patterns ✅ COMPREHENSIVE SESSION OPERATIONS: - StoreSession: Serialize and store session data as JSON files - GetSession: Retrieve and validate sessions with expiration checks - RevokeSession: Delete sessions with not-found error tolerance - CleanupExpiredSessions: Batch cleanup of expired sessions 🚀 ENTERPRISE-GRADE FEATURES: - Persistent storage survives server restarts and failures - Distributed session sharing across SeaweedFS cluster - Configurable storage paths (/seaweedfs/iam/sessions default) - Automatic expiration validation and cleanup - Batch processing for efficient cleanup operations - File-level security with 0600 permissions (owner read/write only) 🔧 SEAMLESS INTEGRATION PATTERNS: - SetFilerClient: Dynamic filer connection configuration - withFilerClient: Consistent error handling and connection management - Compatible with existing SeaweedFS filer client patterns - Follows SeaweedFS pb.WithGrpcFilerClient conventions - Proper gRPC dial options and server addressing ✅ ROBUST ERROR HANDLING & RELIABILITY: - Graceful handling of 'not found' errors during deletion - Automatic cleanup of corrupted session files - Batch listing with pagination (1000 entries per batch) - Proper JSON validation and deserialization error recovery - Connection failure tolerance with detailed error messages 🎯 PRODUCTION USE CASES SUPPORTED: - Multi-node SeaweedFS deployments with shared session state - Session persistence across server restarts and maintenance - Distributed IAM authentication with centralized session storage - Enterprise-grade session management for S3 API access - Scalable session cleanup for high-traffic deployments 🔒 SECURITY & COMPLIANCE: - File permissions set to owner-only access (0600) - Session data encrypted in transit via gRPC - Secure session file naming with .json extension - Automatic expiration enforcement prevents stale sessions - Session revocation immediately removes access This enables enterprise IAM deployments with persistent, distributed session management using SeaweedFS's proven filer infrastructure! All STS tests passing ✅ - Ready for production deployment
