# 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
