TODO for smartconfig

This file tracks improvements and features planned for future releases.

Testing Improvements

Concurrency Tests

• Add comprehensive concurrent access tests for Config struct
• Test race conditions with multiple goroutines accessing/modifying config
• Benchmark concurrent access patterns

Security Tests

• Add tests for malicious input handling in EXEC resolver
• Test various command injection attempts
• Add tests for FILE resolver with symlinks and directory traversal attempts

Performance Tests

• Add comprehensive benchmarks for all resolver types
• Benchmark large configuration files (1MB+, 10MB+, 100MB+)
• Benchmark nested interpolation performance
• Compare performance with other config libraries

Integration Tests

• Add integration tests with mocked cloud services
• Test cloud resolver authentication failures and retry scenarios
• Test timeout behavior for all external resolvers

Documentation

Examples

• Add godoc examples for all major functions
• Create example applications demonstrating common use cases
• Add examples for custom resolver implementation

Guides

• Write troubleshooting guide for common issues
• Create migration guide from popular config libraries (Viper, koanf)
• Write security best practices guide
• Add performance tuning guide

Future Features

Caching Layer (if needed)

• Consider adding optional caching for resolver results
• Implement TTL-based cache invalidation
• Add cache statistics and monitoring

Configuration Validation

• Add optional schema validation support
• Implement type-safe configuration structs
• Add validation rules for common patterns

Watch/Reload Support (if needed)

• Add file watching for configuration changes
• Implement hot reload capability
• Add change notification callbacks

Enhanced Error Handling

• Create typed errors for better error handling
• Add error context with resolution path
• Implement error aggregation for multiple failures

Build and Release

Release Automation

• Set up goreleaser configuration
• Automate changelog generation
• Create release binaries for multiple platforms
• Set up GitHub Actions for CI/CD

Distribution

• Publish to common package managers (Homebrew, apt, etc.)
• Create Docker images with the CLI tool
• Set up automated security scanning
