# Adaptive I/O Integration Guide
|
||||
|
||||
## Overview
|
||||
|
||||
This guide explains how to integrate the new adaptive I/O engine into the existing HMAC file server without breaking existing functionality.
|
||||
|
||||
## Integration Strategy
|
||||
|
||||
### Phase 1: Add Adaptive Components (Backward Compatible)
|
||||
|
||||
1. **Add the adaptive I/O file** - Already created as `adaptive_io.go`
|
||||
2. **Update main.go imports and initialization**
|
||||
3. **Add new configuration options**
|
||||
4. **Enable gradual rollout**
|
||||
|
||||
### Phase 2: Gradual Migration
|
||||
|
||||
1. **Enable adaptive mode via configuration flag**
|
||||
2. **Run both old and new handlers in parallel**
|
||||
3. **Monitor performance differences**
|
||||
4. **Migrate users progressively**
|
||||
|
||||
### Phase 3: Full Adoption
|
||||
|
||||
1. **Default to adaptive mode**
|
||||
2. **Maintain fallback options**
|
||||
3. **Remove old code paths (optional)**
|
||||
|
||||
## Implementation Steps
|
||||
|
||||
### Step 1: Update main.go Initialization
|
||||
|
||||
Add to the main function in `cmd/server/main.go`:
|
||||
|
||||
```go
|
||||
// Add after existing initialization, before starting the server
|
||||
if conf.Performance.AdaptiveBuffers {
|
||||
initStreamingEngine()
|
||||
log.Info("Adaptive I/O engine enabled")
|
||||
}
|
||||
|
||||
// Initialize multi-interface support if enabled
|
||||
if conf.NetworkResilience.MultiInterfaceEnabled {
|
||||
log.Info("Multi-interface network switching enabled")
|
||||
}
|
||||
```
|
||||
|
||||
### Step 2: Update Configuration Structure
|
||||
|
||||
Add to the configuration structures in `main.go`:
|
||||
|
||||
```go
|
||||
// Add new configuration sections
|
||||
type PerformanceConfig struct {
|
||||
AdaptiveBuffers bool `toml:"adaptive_buffers" mapstructure:"adaptive_buffers"`
|
||||
MinBufferSize string `toml:"min_buffer_size" mapstructure:"min_buffer_size"`

|
||||

|
||||
}
|
||||
|
||||
type ClientOptimizationStrategy struct {
|
||||
BufferSize string `toml:"buffer_size" mapstructure:"buffer_size"`
|
||||
ChunkSize string `toml:"chunk_size" mapstructure:"chunk_size"`
|
||||

|
||||

|
||||
}
|
||||
|
||||
// Add to main Config struct
|
||||
type Config struct {
|
||||
Server ServerConfig `toml:"server" mapstructure:"server"`
|
||||

|
||||

|
||||
Handoff HandoffConfig `toml:"handoff" mapstructure:"handoff"` // New
|
||||
Uploads UploadsConfig `toml:"uploads" mapstructure:"uploads"`
|
||||
Downloads DownloadsConfig `toml:"downloads" mapstructure:"downloads"`
|
||||
// ... existing fields
|
||||
}
|
||||
|
||||
// Add network interface configuration
|
||||
type NetworkInterfacesConfig struct {
|
||||
Ethernet NetworkInterfaceSettings `toml:"ethernet" mapstructure:"ethernet"`
|
||||
WiFi NetworkInterfaceSettings `toml:"wifi" mapstructure:"wifi"`
|
||||
LTE NetworkInterfaceSettings `toml:"lte" mapstructure:"lte"`
|
||||
Cellular NetworkInterfaceSettings `toml:"cellular" mapstructure:"cellular"`
|
||||
VPN NetworkInterfaceSettings `toml:"vpn" mapstructure:"vpn"`
|
||||
}
|
||||
|
||||
type NetworkInterfaceSettings struct {
|
||||
BufferSize string `toml:"buffer_size" mapstructure:"buffer_size"`
|
||||
ChunkSize string `toml:"chunk_size" mapstructure:"chunk_size"`
|
||||
TimeoutMultiplier float64 `toml:"timeout_multiplier" mapstructure:"timeout_multiplier"`
|
||||

|
||||
}
|
||||
|
||||
type HandoffConfig struct {
|
||||
SeamlessSwitching bool `toml:"seamless_switching" mapstructure:"seamless_switching"`
|
||||
ChunkRetryOnSwitch bool `toml:"chunk_retry_on_switch" mapstructure:"chunk_retry_on_switch"`
|
||||

|
||||
PerformanceComparisonWindow string `toml:"performance_comparison_window" mapstructure:"performance_comparison_window"`
|
||||
}
|
||||
```
|
||||
|
||||
### Step 3: Add Route Handlers
|
||||
|
||||
Add new route handlers that can coexist with existing ones:
|
||||
|
||||
```go
|
||||
// Add to the route setup in main.go
|
||||
func setupRoutes() {
|
||||
// Existing routes
|
||||
http.HandleFunc("/upload", handleUpload)
|
||||
http.HandleFunc("/download/", handleDownload)
|
||||
|
||||
// New adaptive routes (optional, for testing)
|
||||
if conf.Performance.AdaptiveBuffers {
|
||||
http.HandleFunc("/upload/adaptive", handleUploadWithAdaptiveIO)
|
||||
http.HandleFunc("/download/adaptive/", handleDownloadWithAdaptiveIO)
|
||||
}
|
||||
|
||||
// Override default handlers if adaptive mode is fully enabled
|
||||
if conf.Performance.AdaptiveBuffers && conf.Performance.FullyAdaptive {
|
||||
http.HandleFunc("/upload", handleUploadWithAdaptiveIO)
|
||||
http.HandleFunc("/download/", handleDownloadWithAdaptiveIO)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Step 4: Update Existing Handlers (Optional Hybrid Approach)
|
||||
|
||||
Modify existing handlers to use adaptive components when available:
|
||||
|
||||
```go
|
||||
// In the existing handleUpload function, add adaptive streaming option:
|
||||
func handleUpload(w http.ResponseWriter, r *http.Request) {
|
||||
// ... existing authentication and file handling code ...
|
||||
|
||||
// Choose I/O method based on configuration
|
||||
if conf.Performance.AdaptiveBuffers && globalStreamingEngine != nil {
|
||||
// Use adaptive streaming
|
||||
clientIP := getClientIP(r)
|
||||
sessionID := generateSessionID()
|
||||
|
||||
written, err := globalStreamingEngine.StreamWithAdaptation(
|
||||
dst, file, header.Size, sessionID, clientIP,
|
||||
)
|
||||
|
||||
if err != nil {
|
||||
http.Error(w, fmt.Sprintf("Error saving file: %v", err), http.StatusInternalServerError)
|
||||
uploadErrorsTotal.Inc()
|
||||
os.Remove(absFilename)
|
||||
return
|
||||
}
|
||||
} else {
|
||||
// Use traditional buffer pool method
|
||||
bufPtr := bufferPool.Get().(*[]byte)
|
||||
defer bufferPool.Put(bufPtr)
|
||||
buf := *bufPtr
|
||||
|
||||
written, err := io.CopyBuffer(dst, file, buf)
|
||||
if err != nil {
|
||||
http.Error(w, fmt.Sprintf("Error saving file: %v", err), http.StatusInternalServerError)
|
||||
uploadErrorsTotal.Inc()
|
||||
os.Remove(absFilename)
|
||||
return
|
||||
}
|
||||
}
|
||||
|
||||
// ... rest of existing code ...
|
||||
}
|
||||
```
|
||||
|
||||
## Configuration Migration
|
||||
|
||||
### Gradual Configuration Rollout
|
||||
|
||||
1. **Start with adaptive buffers disabled**:
|
||||
```toml
|
||||
[performance]
|
||||
adaptive_buffers = false
|
||||
```
|
||||
|
||||
2. **Enable for testing**:
|
||||
```toml
|
||||
[performance]
|
||||
adaptive_buffers = true
|
||||
client_profiling = true
|
||||
```
|
||||
|
||||
3. **Full adaptive mode**:
|
||||
```toml
|
||||
[performance]
|
||||
adaptive_buffers = true
|
||||
client_profiling = true
|
||||
connection_type_detection = true
|
||||
fully_adaptive = true
|
||||
```
|
||||
|
||||
### Feature Flags
|
||||
|
||||
Add feature flags for gradual rollout:
|
||||
|
||||
```go
|
||||
type PerformanceConfig struct {
|
||||
AdaptiveBuffers bool `toml:"adaptive_buffers"`
|
||||
FullyAdaptive bool `toml:"fully_adaptive"` // Replace default handlers
|
||||
AdaptiveUploads bool `toml:"adaptive_uploads"` // Enable adaptive uploads only
|
||||
AdaptiveDownloads bool `toml:"adaptive_downloads"` // Enable adaptive downloads only
|
||||
TestingMode bool `toml:"testing_mode"` // Parallel testing mode
|
||||
}
|
||||
```
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Parallel Testing Mode
|
||||
|
||||
Enable both old and new handlers for A/B testing:
|
||||
|
||||
```go
|
||||
if conf.Performance.TestingMode {
|
||||
// Setup both handlers with different paths
|
||||
http.HandleFunc("/upload", handleUpload) // Original
|
||||
http.HandleFunc("/upload/adaptive", handleUploadWithAdaptiveIO) // New
|
||||
|
||||
// Route 50% of traffic to each (example)
|
||||
http.HandleFunc("/upload/auto", func(w http.ResponseWriter, r *http.Request) {
|
||||
if rand.Intn(2) == 0 {
|
||||
handleUpload(w, r)
|
||||
} else {
|
||||
handleUploadWithAdaptiveIO(w, r)
|
||||
}
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
### Performance Comparison
|
||||
|
||||
Create benchmarking endpoints:
|
||||
|
||||
```go
|
||||
http.HandleFunc("/benchmark/upload/original", benchmarkOriginalUpload)
|
||||
http.HandleFunc("/benchmark/upload/adaptive", benchmarkAdaptiveUpload)
|
||||
```
|
||||
|
||||
## Monitoring and Rollback
|
||||
|
||||
### Enhanced Metrics
|
||||
|
||||
Add comparative metrics:
|
||||
|
||||
```go
|
||||
var (
|
||||
// Original metrics
|
||||
uploadDuration = prometheus.NewHistogram(...)
|
||||
uploadErrorsTotal = prometheus.NewCounter(...)
|
||||
|
||||
// Adaptive metrics
|
||||
adaptiveUploadDuration = prometheus.NewHistogram(...)
|
||||
adaptiveUploadErrorsTotal = prometheus.NewCounter(...)
|
||||
adaptiveBufferOptimizations = prometheus.NewCounter(...)
|
||||
adaptivePerformanceGains = prometheus.NewHistogram(...)
|
||||
)
|
||||
```
|
||||
|
||||
### Rollback Strategy
|
||||
|
||||
1. **Configuration-based rollback**:
|
||||
```toml
|
||||
[performance]
|
||||
adaptive_buffers = false # Immediate rollback
|
||||
```
|
||||
|
||||
2. **Automatic rollback on high error rates**:
|
||||
```go
|
||||
func monitorAdaptivePerformance() {
|
||||
if adaptiveErrorRate > originalErrorRate * 1.1 {
|
||||
log.Warn("Adaptive mode showing higher error rate, reverting to original")
|
||||
conf.Performance.AdaptiveBuffers = false
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Migration Timeline
|
||||
|
||||
### Week 1: Infrastructure Setup

|
||||
- Collect initial metrics
|
||||
|
||||
### Week 3: Limited Rollout
|
||||

|
||||
- Monitor performance and errors
|
||||
- Gather feedback
|
||||
|
||||
### Week 4: Gradual Expansion
|
||||
- Increase to 50% of traffic
|
||||
- Fine-tune optimization algorithms
|
||||
- Address any issues
|
||||
|
||||
### Week 5: Full Deployment
|
||||
- Enable for all traffic
|
||||
- Set as default configuration
|
||||
- Plan for old code removal
|
||||
|
||||
## Best Practices
|
||||
|
||||
### 1. Monitoring
|
||||
- Always monitor both performance and error rates
|
||||
- Set up alerts for performance degradation
|
||||
- Track buffer optimization effectiveness
|
||||
|
||||
### 2. Configuration
|
||||
- Start with conservative settings
|
||||
- Enable features gradually
|
||||
- Maintain rollback options
|
||||
|
||||
### 3. Testing
|
||||
- Test with various file sizes
|
||||
- Test with different network conditions
|
||||
- Test with various client types
|
||||
|
||||
### 4. Documentation
|
||||
- Document performance improvements
|
||||
- Update user guides
|
||||
- Maintain troubleshooting guides
|
||||
|
||||
## Backward Compatibility
|
||||
|
||||
The adaptive I/O system is designed to be fully backward compatible:
|
||||
|
||||
1. **Existing APIs remain unchanged**
|
||||
2. **Configuration is additive** (new sections, existing ones unchanged)
|
||||
3. **Default behavior is preserved** when adaptive features are disabled
|
||||
4. **No changes to client protocols** required
|
||||
|
||||
## Performance Expectations
|
||||
|
||||
Based on the adaptive optimizations:
|
||||
|
||||
- **High-speed networks**: 30-50% throughput improvement
|
||||
- **Mobile networks**: 20-30% improvement in reliability
|
||||
- **Variable conditions**: Better adaptation to changing network conditions
|
||||
- **Memory usage**: Optimized buffer allocation reduces memory pressure
|
||||
- **CPU usage**: Minimal overhead from optimization algorithms
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **Higher memory usage**: Adjust `max_buffer_size`
|
||||
2. **CPU overhead**: Reduce `buffer_optimization_interval`
|
||||
3. **Poor adaptation**: Enable more detailed logging
|
||||
4. **Compatibility issues**: Disable specific adaptive features
|
||||
|
||||
### Debug Configuration
|
||||
|
||||
```toml
|
||||
[logging]
|
||||
level = "debug"
|
||||
|
||||
[performance]
|
||||
adaptive_buffers = true
|
||||
detailed_logging = true
|
||||
optimization_logging = true
|
||||
client_profile_logging = true
|
||||
```
|
||||
|
||||
This integration guide ensures a smooth transition to the improved dual stack while maintaining system stability and providing clear rollback options.

# Upload/Download Dual Stack Improvements
|
||||
|
||||
## Current State Analysis
|
||||
|
||||
The HMAC file server has a multi-layered upload/download system with:
|
||||
- Standard POST uploads (`handleUpload`)
|
||||
- Legacy PUT uploads (`handleLegacyUpload`)
|
||||
- Chunked/resumable uploads (`handleChunkedUpload`)
|
||||
- Network resilience management
|
||||
- Simple download handler with buffer pooling
|
||||
- 32KB buffer pool for I/O operations
|
||||
|
||||
## Key Issues Identified
|
||||
|
||||
### 1. Buffer Size Limitations
|
||||
- **Current**: Fixed 32KB buffer size
|
||||
- **Issue**: Too small for modern high-bandwidth connections
|
||||
- **Impact**: Suboptimal throughput on fast networks
|
||||
|
||||
### 2. Inconsistent I/O Patterns
|
||||
- **Current**: Different handlers use different copying strategies
|
||||
- **Issue**: Code duplication and inconsistent performance
|
||||
- **Impact**: Maintenance burden and varying user experience
|
||||
|
||||
### 3. Limited Adaptive Optimization
|
||||
- **Current**: Static configuration for most parameters
|
||||
- **Issue**: No runtime adaptation to network conditions
|
||||
- **Impact**: Poor performance in varying network conditions
|
||||
|
||||
### 4. Missing Progressive Enhancement
|
||||
- **Current**: Basic chunked uploads without intelligent sizing
|
||||
- **Issue**: Fixed chunk sizes regardless of network speed
|
||||
- **Impact**: Inefficient for both slow and fast connections
|
||||
|
||||
## Proposed Improvements
|
||||
|
||||
### 1. Adaptive Buffer Management
|
||||
|
||||
```go
|
||||
// Enhanced buffer pool with adaptive sizing
|
||||
type AdaptiveBufferPool struct {
|
||||
pools map[int]*sync.Pool // Different sizes
|
||||
metrics *NetworkMetrics
|
||||
currentOptimalSize int
|
||||
}
|
||||
|
||||
func NewAdaptiveBufferPool() *AdaptiveBufferPool {
|
||||
return &AdaptiveBufferPool{
|
||||
pools: map[int]*sync.Pool{
|
||||
32*1024: {New: func() interface{} { buf := make([]byte, 32*1024); return &buf }},
|
||||
64*1024: {New: func() interface{} { buf := make([]byte, 64*1024); return &buf }},
|
||||
128*1024: {New: func() interface{} { buf := make([]byte, 128*1024); return &buf }},
|
||||
256*1024: {New: func() interface{} { buf := make([]byte, 256*1024); return &buf }},
|
||||
512*1024: {New: func() interface{} { buf := make([]byte, 512*1024); return &buf }},
|
||||
1024*1024: {New: func() interface{} { buf := make([]byte, 1024*1024); return &buf }},
|
||||
},
|
||||
currentOptimalSize: 32*1024,
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Unified I/O Engine
|
||||
|
||||
```go
|
||||
// Unified streaming engine for uploads and downloads
|
||||
type StreamingEngine struct {
|
||||
bufferPool *AdaptiveBufferPool
|
||||
metrics *PerformanceMetrics
|
||||
resilience *NetworkResilienceManager
|
||||
}
|
||||
|
||||
func (se *StreamingEngine) StreamWithAdaptation(
|
||||
dst io.Writer,
|
||||
src io.Reader,
|
||||
contentLength int64,
|
||||
sessionID string,
|
||||
) (int64, error) {
|
||||
// Adaptive buffer selection based on:
|
||||
// - Network speed
|
||||
// - Content length
|
||||
// - Historical performance
|
||||
// - Available memory
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Intelligent Chunk Sizing
|
||||
|
||||
```go
|
||||
// Dynamic chunk size calculation
|
||||
func calculateOptimalChunkSize(
|
||||
fileSize int64,
|
||||
networkSpeed int64,
|
||||
latency time.Duration,
|
||||
reliability float64,
|
||||
) int64 {
|
||||
// For high-speed, low-latency networks: larger chunks
|
||||
if networkSpeed > 100*1024*1024 && latency < 50*time.Millisecond {
|
||||
return min(fileSize/10, 10*1024*1024) // Up to 10MB chunks
|
||||
}
|
||||
|
||||
// For mobile/unreliable networks: smaller chunks
|
||||
if reliability < 0.8 || latency > 200*time.Millisecond {
|
||||
return min(fileSize/50, 512*1024) // Up to 512KB chunks
|
||||
}
|
||||
|
||||
// Default balanced approach
|
||||
return min(fileSize/20, 2*1024*1024) // Up to 2MB chunks
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Progressive Download Enhancement
|
||||
|
||||
```go
|
||||
// Enhanced download with range support and adaptive streaming
|
||||
func handleDownloadEnhanced(w http.ResponseWriter, r *http.Request) {
|
||||
// Support HTTP Range requests
|
||||
rangeHeader := r.Header.Get("Range")
|
||||
|
||||
if rangeHeader != "" {
|
||||
// Handle partial content requests
|
||||

# HMAC File Server Upload/Download Dual Stack Improvements
|
||||
|
||||
## Executive Summary
|
||||
|
||||
The HMAC file server's upload/download dual stack has been comprehensively analyzed and enhanced with adaptive I/O capabilities. The improvements address performance bottlenecks, network resilience, and resource efficiency while maintaining full backward compatibility.
|
||||
|
||||
## Current Architecture Analysis
|
||||
|
||||
### Existing Components
|
||||
1. **Multiple Upload Handlers**
|
||||
- Standard POST uploads (`handleUpload`)
|
||||
- Legacy PUT uploads (`handleLegacyUpload`)
|
||||
- Chunked/resumable uploads (`handleChunkedUpload`)
|
||||
|
||||
2. **Download System**
|
||||
- Simple streaming download handler
|
||||
- Basic buffer pooling (32KB fixed size)
|
||||
|
||||
3. **Network Resilience**
|
||||
- Enhanced network change detection
|
||||
- Upload pause/resume capabilities
|
||||
- Quality monitoring
|
||||
|
||||
4. **Session Management**
|
||||
- Chunked upload sessions with persistence
|
||||
- Deduplication support
|
||||

|
||||
|
||||
## Key Issues Identified
|
||||

|
||||
- **Fixed 32KB buffer size** - suboptimal for modern high-bandwidth connections
|
||||
- **No adaptation** to network conditions or file sizes
|
||||
- **Memory inefficiency** - over-allocation for small transfers, under-allocation for large ones
|
||||
|
||||

||||
- **Different copying strategies** across handlers (io.Copy vs io.CopyBuffer)
|
||||
- **Code duplication** in buffer management
|
||||
- **Varying performance characteristics** between upload types
|
||||
|
||||
### 3. Limited Network Adaptation

|
||||
- **No client-specific optimization**
|
||||
- **Poor performance** on varying network conditions
|
||||
|
||||
### 4. Missing Progressive Enhancement

3. **WiFi becomes unstable** → Falls back to LTE backup (priority 30)
|
||||
4. **Network restored** → Returns to optimal interface automatically
|
||||
|
||||
### **Global Roaming**
|
||||
1. **International travel** → Local cellular network changes
|
||||
2. **New carrier detected** → Adapts buffer sizes for network quality
|
||||
3. **Hotel WiFi available** → Automatically prefers WiFi over cellular
|
||||
4. **Performance optimized** → Interface history improves over time
