# Connection Cleanup Code Patterns
## Pattern 1: Safe Connection Cleanup
```typescript
public initiateCleanupOnce(record: IConnectionRecord, reason: string = 'normal'): void {
// Prevent duplicate cleanup
if (record.incomingTerminationReason === null ||
record.incomingTerminationReason === undefined) {
record.incomingTerminationReason = reason;
this.incrementTerminationStat('incoming', reason);
}
this.cleanupConnection(record, reason);
}
public cleanupConnection(record: IConnectionRecord, reason: string = 'normal'): void {
if (!record.connectionClosed) {
record.connectionClosed = true;
// Remove from tracking immediately
this.connectionRecords.delete(record.id);
this.securityManager.removeConnectionByIP(record.remoteIP, record.id);
// Clear timers
if (record.cleanupTimer) {
clearTimeout(record.cleanupTimer);
record.cleanupTimer = undefined;
}
// Clean up sockets
this.cleanupSocket(record, 'incoming', record.incoming);
if (record.outgoing) {
this.cleanupSocket(record, 'outgoing', record.outgoing);
}
// Clear memory
record.pendingData = [];
record.pendingDataSize = 0;
}
}
```
## Pattern 2: Socket Cleanup with Retry
```typescript
private cleanupSocket(
record: IConnectionRecord,
side: 'incoming' | 'outgoing',
socket: plugins.net.Socket
): void {
try {
if (!socket.destroyed) {
// Graceful shutdown first
socket.end();
// Force destroy after timeout
const socketTimeout = setTimeout(() => {
try {
if (!socket.destroyed) {
socket.destroy();
}
} catch (err) {
console.log(`[${record.id}] Error destroying ${side} socket: ${err}`);
}
}, 1000);
// Don't block process exit
if (socketTimeout.unref) {
socketTimeout.unref();
}
}
} catch (err) {
console.log(`[${record.id}] Error closing ${side} socket: ${err}`);
// Fallback to destroy
try {
if (!socket.destroyed) {
socket.destroy();
}
} catch (destroyErr) {
console.log(`[${record.id}] Error destroying ${side} socket: ${destroyErr}`);
}
}
}
```
## Pattern 3: NetworkProxy Bridge Cleanup
```typescript
public async forwardToNetworkProxy(
connectionId: string,
socket: plugins.net.Socket,
record: IConnectionRecord,
initialChunk: Buffer,
networkProxyPort: number,
cleanupCallback: (reason: string) => void
): Promise<void> {
const proxySocket = new plugins.net.Socket();
// Connect to NetworkProxy
await new Promise<void>((resolve, reject) => {
proxySocket.connect(networkProxyPort, 'localhost', () => {
resolve();
});
proxySocket.on('error', reject);
});
// Send initial data
if (initialChunk) {
proxySocket.write(initialChunk);
}
// Setup bidirectional piping
socket.pipe(proxySocket);
proxySocket.pipe(socket);
// Comprehensive cleanup handler
const cleanup = (reason: string) => {
// Unpipe to prevent data loss
socket.unpipe(proxySocket);
proxySocket.unpipe(socket);
// Destroy proxy socket
proxySocket.destroy();
// Notify SmartProxy
cleanupCallback(reason);
};
// Setup all cleanup triggers
socket.on('end', () => cleanup('socket_end'));
socket.on('error', () => cleanup('socket_error'));
proxySocket.on('end', () => cleanup('proxy_end'));
proxySocket.on('error', () => cleanup('proxy_error'));
}
```
## Pattern 4: Error Handler with Cleanup
```typescript
public handleError(side: 'incoming' | 'outgoing', record: IConnectionRecord) {
return (err: Error) => {
const code = (err as any).code;
let reason = 'error';
// Map error codes to reasons
switch (code) {
case 'ECONNRESET':
reason = 'econnreset';
break;
case 'ETIMEDOUT':
reason = 'etimedout';
break;
case 'ECONNREFUSED':
reason = 'connection_refused';
break;
case 'EHOSTUNREACH':
reason = 'host_unreachable';
break;
}
// Log with context
const duration = Date.now() - record.incomingStartTime;
console.log(
`[${record.id}] ${code} on ${side} side from ${record.remoteIP}. ` +
`Duration: ${plugins.prettyMs(duration)}`
);
// Track termination reason
if (side === 'incoming' && record.incomingTerminationReason === null) {
record.incomingTerminationReason = reason;
this.incrementTerminationStat('incoming', reason);
}
// Initiate cleanup
this.initiateCleanupOnce(record, reason);
};
}
```
## Pattern 5: Inactivity Check with Cleanup
```typescript
public performInactivityCheck(): void {
const now = Date.now();
const connectionIds = [...this.connectionRecords.keys()];
for (const id of connectionIds) {
const record = this.connectionRecords.get(id);
if (!record) continue;
// Skip if disabled or immortal
if (this.settings.disableInactivityCheck ||
(record.hasKeepAlive && this.settings.keepAliveTreatment === 'immortal')) {
continue;
}
const inactivityTime = now - record.lastActivity;
let effectiveTimeout = this.settings.inactivityTimeout!;
// Extended timeout for keep-alive
if (record.hasKeepAlive && this.settings.keepAliveTreatment === 'extended') {
effectiveTimeout *= (this.settings.keepAliveInactivityMultiplier || 6);
}
if (inactivityTime > effectiveTimeout && !record.connectionClosed) {
// Warn before closing keep-alive connections
if (record.hasKeepAlive && !record.inactivityWarningIssued) {
console.log(`[${id}] Warning: Keep-alive connection inactive`);
record.inactivityWarningIssued = true;
// Grace period
record.lastActivity = now - (effectiveTimeout - 600000);
} else {
// Close the connection
console.log(`[${id}] Closing due to inactivity`);
this.cleanupConnection(record, 'inactivity');
}
}
}
}
```
## Pattern 6: Complete Shutdown
```typescript
public clearConnections(): void {
const connectionIds = [...this.connectionRecords.keys()];
// Phase 1: Graceful end
for (const id of connectionIds) {
const record = this.connectionRecords.get(id);
if (record) {
try {
// Clear timers
if (record.cleanupTimer) {
clearTimeout(record.cleanupTimer);
record.cleanupTimer = undefined;
}
// Graceful socket end
if (record.incoming && !record.incoming.destroyed) {
record.incoming.end();
}
if (record.outgoing && !record.outgoing.destroyed) {
record.outgoing.end();
}
} catch (err) {
console.log(`Error during graceful end: ${err}`);
}
}
}
// Phase 2: Force destroy after delay
setTimeout(() => {
for (const id of connectionIds) {
const record = this.connectionRecords.get(id);
if (record) {
try {
// Remove all listeners
if (record.incoming) {
record.incoming.removeAllListeners();
if (!record.incoming.destroyed) {
record.incoming.destroy();
}
}
if (record.outgoing) {
record.outgoing.removeAllListeners();
if (!record.outgoing.destroyed) {
record.outgoing.destroy();
}
}
} catch (err) {
console.log(`Error during forced destruction: ${err}`);
}
}
}
// Clear all tracking
this.connectionRecords.clear();
this.terminationStats = { incoming: {}, outgoing: {} };
}, 100);
}
```
## Pattern 7: Safe Event Handler Removal
```typescript
// Store handlers for later removal
record.renegotiationHandler = this.tlsManager.createRenegotiationHandler(
connectionId,
serverName,
connInfo,
(connectionId, reason) => this.connectionManager.initiateCleanupOnce(record, reason)
);
// Add the handler
socket.on('data', record.renegotiationHandler);
// Remove during cleanup
if (record.incoming) {
try {
record.incoming.removeAllListeners('data');
record.renegotiationHandler = undefined;
} catch (err) {
console.log(`[${record.id}] Error removing data handlers: ${err}`);
}
}
```
## Pattern 8: Connection State Tracking
```typescript
interface IConnectionRecord {
id: string;
connectionClosed: boolean;
incomingTerminationReason: string | null;
outgoingTerminationReason: string | null;
cleanupTimer?: NodeJS.Timeout;
renegotiationHandler?: Function;
// ... other fields
}
// Check state before operations
if (!record.connectionClosed) {
// Safe to perform operations
}
// Track cleanup state
record.connectionClosed = true;
```
## Key Principles
1. **Idempotency**: Cleanup operations should be safe to call multiple times
2. **State Tracking**: Always track connection and cleanup state
3. **Error Resilience**: Handle errors during cleanup gracefully
4. **Resource Release**: Clear all references (timers, handlers, buffers)
5. **Graceful First**: Try graceful shutdown before forced destroy
6. **Comprehensive Coverage**: Handle all possible termination scenarios
7. **Logging**: Track termination reasons for debugging
8. **Memory Safety**: Clear data structures to prevent leaks

# Connection Termination Issues and Solutions in SmartProxy/NetworkProxy
## Common Connection Termination Scenarios
### 1. Normal Connection Closure
**Flow**:
- Client or server initiates graceful close
- 'close' event triggers cleanup
- Connection removed from tracking
- Resources freed
**Code Path**:
```typescript
// In ConnectionManager
handleClose(side: 'incoming' | 'outgoing', record: IConnectionRecord) {
record.incomingTerminationReason = 'normal';
this.initiateCleanupOnce(record, 'closed_' + side);
}
```
### 2. Error-Based Termination
**Common Errors**:
- ECONNRESET: Connection reset by peer
- ETIMEDOUT: Connection timed out
- ECONNREFUSED: Connection refused
- EHOSTUNREACH: Host unreachable
**Handling**:
```typescript
handleError(side: 'incoming' | 'outgoing', record: IConnectionRecord) {
return (err: Error) => {
const code = (err as any).code;
let reason = 'error';
if (code === 'ECONNRESET') {
reason = 'econnreset';
} else if (code === 'ETIMEDOUT') {
reason = 'etimedout';
}
this.initiateCleanupOnce(record, reason);
};
}
```
### 3. Inactivity Timeout
**Detection**:
```typescript
performInactivityCheck(): void {
const now = Date.now();
for (const record of this.connectionRecords.values()) {
const inactivityTime = now - record.lastActivity;
if (inactivityTime > effectiveTimeout) {
this.cleanupConnection(record, 'inactivity');
}
}
}
```
**Special Cases**:
- Keep-alive connections get extended timeouts
- "Immortal" connections bypass inactivity checks
- Warning issued before closure for keep-alive connections
### 4. NFTables-Handled Connections
**Special Handling**:
```typescript
if (route.action.forwardingEngine === 'nftables') {
socket.end();
record.nftablesHandled = true;
this.connectionManager.initiateCleanupOnce(record, 'nftables_handled');
return;
}
```
These connections are:
- Handled at kernel level
- Closed immediately at application level
- Tracked for metrics only
### 5. NetworkProxy Bridge Termination
**Bridge Cleanup**:
```typescript
const cleanup = (reason: string) => {
socket.unpipe(proxySocket);
proxySocket.unpipe(socket);
proxySocket.destroy();
cleanupCallback(reason);
};
socket.on('end', () => cleanup('socket_end'));
socket.on('error', () => cleanup('socket_error'));
proxySocket.on('end', () => cleanup('proxy_end'));
proxySocket.on('error', () => cleanup('proxy_error'));
```
## Preventing Connection Leaks
### 1. Always Remove Event Listeners
```typescript
cleanupConnection(record: IConnectionRecord, reason: string): void {
if (record.incoming) {
record.incoming.removeAllListeners('data');
record.renegotiationHandler = undefined;
}
}
```
### 2. Clear Timers
```typescript
if (record.cleanupTimer) {
clearTimeout(record.cleanupTimer);
record.cleanupTimer = undefined;
}
```
### 3. Proper Socket Cleanup
```typescript
private cleanupSocket(record: IConnectionRecord, side: string, socket: net.Socket): void {
try {
if (!socket.destroyed) {
socket.end(); // Graceful
setTimeout(() => {
if (!socket.destroyed) {
socket.destroy(); // Forced
}
}, 1000);
}
} catch (err) {
console.log(`Error closing ${side} socket: ${err}`);
}
}
```
### 4. Connection Record Cleanup
```typescript
// Clear pending data to prevent memory leaks
record.pendingData = [];
record.pendingDataSize = 0;
// Remove from tracking map
this.connectionRecords.delete(record.id);
```
## Monitoring and Debugging
### 1. Termination Statistics
```typescript
private terminationStats: {
incoming: Record<string, number>;
outgoing: Record<string, number>;
} = { incoming: {}, outgoing: {} };
incrementTerminationStat(side: 'incoming' | 'outgoing', reason: string): void {
this.terminationStats[side][reason] = (this.terminationStats[side][reason] || 0) + 1;
}
```
### 2. Connection Logging
**Detailed Logging**:
```typescript
console.log(
`[${record.id}] Connection from ${record.remoteIP} terminated (${reason}).` +
` Duration: ${prettyMs(duration)}, Bytes IN: ${bytesReceived}, OUT: ${bytesSent}`
);
```
### 3. Active Connection Tracking
```typescript
getConnectionCount(): number {
return this.connectionRecords.size;
}
// In NetworkProxy
metrics = {
activeConnections: this.connectedClients,
portProxyConnections: this.portProxyConnections,
tlsTerminatedConnections: this.tlsTerminatedConnections
};
```
## Best Practices for Connection Termination
1. **Always Use initiateCleanupOnce()**:
- Prevents duplicate cleanup operations
- Ensures proper termination reason tracking
2. **Handle All Socket Events**:
- 'error', 'close', 'end' events
- Both incoming and outgoing sockets
3. **Implement Proper Timeouts**:
- Initial data timeout
- Inactivity timeout
- Maximum connection lifetime
4. **Track Resources**:
- Connection records
- Socket maps
- Timer references
5. **Log Termination Reasons**:
- Helps debug connection issues
- Provides metrics for monitoring
6. **Graceful Shutdown**:
- Try socket.end() before socket.destroy()
- Allow time for graceful closure
7. **Memory Management**:
- Clear pending data buffers
- Remove event listeners
- Delete connection records
## Common Issues and Solutions
### Issue: Memory Leaks from Event Listeners
**Solution**: Always call removeAllListeners() during cleanup
### Issue: Orphaned Connections
**Solution**: Implement multiple cleanup triggers (timeout, error, close)
### Issue: Duplicate Cleanup Operations
**Solution**: Use connectionClosed flag and initiateCleanupOnce()
### Issue: Hanging Connections
**Solution**: Implement inactivity checks and maximum lifetime limits
### Issue: Resource Exhaustion
**Solution**: Track connection counts and implement limits
### Issue: Lost Data During Cleanup
**Solution**: Use proper unpipe operations and graceful shutdown
### Issue: Debugging Connection Issues
**Solution**: Track termination reasons and maintain detailed logs

# NetworkProxy Connection Termination and SmartProxy Connection Handling
## Overview
The connection management between NetworkProxy and SmartProxy involves complex coordination to handle TLS termination, connection forwarding, and proper cleanup. This document outlines how these systems work together.
## SmartProxy Connection Management
### Connection Tracking (ConnectionManager)
1. **Connection Lifecycle**:
- New connections are registered in `ConnectionManager.createConnection()`
- Each connection gets a unique ID and tracking record
- Connection records track both incoming (client) and outgoing (target) sockets
- Connections are removed from tracking upon cleanup
2. **Connection Cleanup Flow**:
```
initiateCleanupOnce() -> cleanupConnection() -> cleanupSocket()
```
- `initiateCleanupOnce()`: Prevents duplicate cleanup operations
- `cleanupConnection()`: Main cleanup logic, removes connections from tracking
- `cleanupSocket()`: Handles socket termination (graceful end, then forced destroy)
3. **Cleanup Triggers**:
- Socket errors (ECONNRESET, ETIMEDOUT, etc.)
- Socket close events
- Inactivity timeouts
- Connection lifetime limits
- Manual cleanup (e.g., NFTables-handled connections)
## NetworkProxy Integration
### NetworkProxyBridge
The `NetworkProxyBridge` class manages the connection between SmartProxy and NetworkProxy:
1. **Connection Forwarding**:
```typescript
forwardToNetworkProxy(
connectionId: string,
socket: net.Socket,
record: IConnectionRecord,
initialChunk: Buffer,
networkProxyPort: number,
cleanupCallback: (reason: string) => void
)
```
- Creates a new socket connection to NetworkProxy
- Pipes data between client and NetworkProxy sockets
- Sets up cleanup handlers for both sockets
2. **Cleanup Coordination**:
- When either socket ends or errors, both are cleaned up
- Cleanup callback notifies SmartProxy's ConnectionManager
- Proper unpipe operations prevent memory leaks
## NetworkProxy Connection Tracking
### Connection Tracking in NetworkProxy
1. **Raw TCP Connection Tracking**:
```typescript
setupConnectionTracking(): void {
this.httpsServer.on('connection', (connection: net.Socket) => {
// Track connections in socketMap
this.socketMap.add(connection);
// Setup cleanup handlers
connection.on('close', cleanupConnection);
connection.on('error', cleanupConnection);
connection.on('end', cleanupConnection);
});
}
```
2. **SmartProxy Connection Detection**:
- Connections from localhost (127.0.0.1) are identified as SmartProxy connections
- Special counter tracks `portProxyConnections`
- Connection counts are updated when connections close
3. **Metrics and Monitoring**:
- Active connections tracked in `connectedClients`
- TLS handshake completions tracked in `tlsTerminatedConnections`
- Connection pool status monitored periodically
## Connection Termination Flow
### Typical TLS Termination Flow:
1. Client connects to SmartProxy
2. SmartProxy creates connection record and tracks socket
3. SmartProxy determines route requires TLS termination
4. NetworkProxyBridge forwards connection to NetworkProxy
5. NetworkProxy performs TLS termination
6. Data flows through piped sockets
7. When connection ends:
- NetworkProxy cleans up its socket tracking
- NetworkProxyBridge handles cleanup coordination
- SmartProxy's ConnectionManager removes connection record
- All resources are properly released
### Cleanup Coordination Points:
1. **SmartProxy Cleanup**:
- ConnectionManager tracks all cleanup reasons
- Socket handlers removed to prevent memory leaks
- Timeout timers cleared
- Connection records removed from maps
- Security manager notified of connection removal
2. **NetworkProxy Cleanup**:
- Sockets removed from tracking map
- Connection counters updated
- Metrics updated for monitoring
- Connection pool resources freed
3. **Bridge Cleanup**:
- Unpipe operations prevent data loss
- Both sockets properly destroyed
- Cleanup callback ensures SmartProxy is notified
## Important Considerations
1. **Memory Management**:
- All event listeners must be removed during cleanup
- Proper unpipe operations prevent memory leaks
- Connection records cleared from all tracking maps
2. **Error Handling**:
- Multiple cleanup mechanisms prevent orphaned connections
- Graceful shutdown attempted before forced destruction
- Timeout mechanisms ensure cleanup even in edge cases
3. **State Consistency**:
- Connection closed flags prevent duplicate cleanup
- Termination reasons tracked for debugging
- Activity timestamps updated for accurate timeout handling
4. **Performance**:
- Connection pools minimize TCP handshake overhead
- Efficient socket tracking using Maps
- Periodic cleanup prevents resource accumulation
## Best Practices
1. Always use `initiateCleanupOnce()` to prevent duplicate cleanup operations
2. Track termination reasons for debugging and monitoring
3. Ensure all event listeners are removed during cleanup
4. Use proper unpipe operations when breaking socket connections
5. Monitor connection counts and cleanup statistics
6. Implement proper timeout handling for all connection types
7. Keep socket tracking maps synchronized with actual socket state

- `networkProxyPort` → `httpProxyPort`
## Migration Guide
For users upgrading to the new version:
```typescript
// Old code
import { NetworkProxy } from '@push.rocks/smartproxy';
const proxy = new NetworkProxy({ port: 8080 });
// New code
import { HttpProxy } from '@push.rocks/smartproxy';
const proxy = new HttpProxy({ port: 8080 });
// Configuration changes
const config = {
// Old
useNetworkProxy: [443],
networkProxyPort: 8443,
// New
useHttpProxy: [443],
httpProxyPort: 8443,
};
```
## Next Steps
With this refactoring complete, the codebase is now better positioned for:
1. Adding HTTP/3 (QUIC) support
2. Implementing advanced HTTP features
3. Building an HTTP middleware system
4. Protocol-specific optimizations
5. Enhanced HTTP/2 multiplexing
## Conclusion
The refactoring has successfully achieved its goals of providing clearer separation of concerns, better naming, and improved organization while maintaining backward compatibility where possible. The SmartProxy architecture is now more maintainable and extensible for future enhancements.

# SmartProxy ACME Simplification Implementation Summary
## Overview
We successfully implemented comprehensive support for both global and route-level ACME configuration in SmartProxy v19.0.0, addressing the certificate acquisition issues and improving the developer experience.
## What Was Implemented
### 1. Enhanced Configuration Support
- Added global ACME configuration at the SmartProxy level
- Maintained support for route-level ACME configuration
- Implemented configuration hierarchy where global settings serve as defaults
- Route-level settings override global defaults when specified
### 2. Updated Core Components
#### SmartProxy Class (`smart-proxy.ts`)
- Enhanced ACME configuration normalization in constructor
- Added support for both `email` and `accountEmail` fields
- Updated `initializeCertificateManager` to prioritize configurations correctly
- Added `validateAcmeConfiguration` method for comprehensive validation
#### SmartCertManager Class (`certificate-manager.ts`)
- Added `globalAcmeDefaults` property to store top-level configuration
- Implemented `setGlobalAcmeDefaults` method
- Updated `provisionAcmeCertificate` to use global defaults
- Enhanced error messages to guide users to correct configuration
#### ISmartProxyOptions Interface (`interfaces.ts`)
- Added comprehensive documentation for global ACME configuration
- Enhanced IAcmeOptions interface with better field descriptions
- Added example usage in JSDoc comments
### 3. Configuration Validation
- Checks for missing ACME email configuration
- Validates port 80 availability for HTTP-01 challenges
- Warns about wildcard domains with auto certificates
- Detects environment mismatches between global and route configs
### 4. Test Coverage
Created comprehensive test suite (`test.acme-configuration.node.ts`):
- Top-level ACME configuration
- Route-level ACME configuration
- Mixed configuration with overrides
- Error handling for missing email
- Support for accountEmail alias
### 5. Documentation Updates
#### Main README (`readme.md`)
- Added global ACME configuration example
- Updated code examples to show both configuration styles
- Added dedicated ACME configuration section
#### Certificate Management Guide (`certificate-management.md`)
- Updated for v19.0.0 changes
- Added configuration hierarchy explanation
- Included troubleshooting section
- Added migration guide from v18
#### Readme Hints (`readme.hints.md`)
- Added breaking change warning for ACME configuration
- Included correct configuration example
- Added migration considerations
## Key Benefits
1. **Reduced Configuration Duplication**: Global ACME settings eliminate need to repeat configuration
2. **Better Developer Experience**: Clear error messages guide users to correct configuration
3. **Backward Compatibility**: Route-level configuration still works as before
4. **Flexible Configuration**: Can mix global defaults with route-specific overrides
5. **Improved Validation**: Warns about common configuration issues
## Testing Results
All tests pass successfully:
- Global ACME configuration works correctly
- Route-level configuration continues to function
- Configuration hierarchy behaves as expected
- Error messages provide clear guidance
## Migration Path
For users upgrading from v18:
1. Existing route-level ACME configuration continues to work
2. Can optionally move common settings to global level
3. Route-specific overrides remain available
4. No breaking changes for existing configurations
## Conclusion
The implementation successfully addresses the original issue where SmartAcme was not initialized due to missing configuration. Users now have flexible options for configuring ACME, with clear error messages and comprehensive documentation to guide them.

# SmartProxy Development Plan # SmartProxy Architecture Refactoring Plan
cat /home/philkunz/.claude/CLAUDE.md ## Overview
## Critical Bug Fix: Port 80 EADDRINUSE with ACME Challenge Routes Refactor the proxy architecture to provide clearer separation of concerns between HTTP/HTTPS traffic handling and low-level connection routing.
### Problem Statement ## Current Architecture Problems
SmartProxy encounters an "EADDRINUSE" error on port 80 when provisioning multiple ACME certificates. The issue occurs because the certificate manager adds and removes the challenge route for each certificate individually, causing race conditions when multiple certificates are provisioned concurrently.
### Root Cause 1. NetworkProxy name doesn't clearly indicate it handles HTTP/HTTPS
The `SmartCertManager` class adds the ACME challenge route (port 80) before provisioning each certificate and removes it afterward. When multiple certificates are provisioned: 2. HTTP parsing logic is duplicated in RouteConnectionHandler
1. Each provisioning cycle adds its own challenge route 3. Redirect and static route handling is embedded in SmartProxy
2. This triggers `updateRoutes()` which calls `PortManager.updatePorts()` 4. Unclear separation between TCP routing and HTTP processing
3. Port 80 is repeatedly added/removed, causing binding conflicts
### Implementation Plan ## Proposed Architecture
#### Phase 1: Refactor Challenge Route Lifecycle ### HttpProxy (renamed from NetworkProxy)
1. **Modify challenge route handling** in `SmartCertManager` **Purpose**: Handle all HTTP/HTTPS traffic with TLS termination
- [x] Add challenge route once during initialization if ACME is configured
- [x] Keep challenge route active throughout entire certificate provisioning
- [x] Remove challenge route only after all certificates are provisioned
- [x] Add concurrency control to prevent multiple simultaneous route updates
#### Phase 2: Update Certificate Provisioning Flow **Responsibilities**:
2. **Refactor certificate provisioning methods** - TLS termination for HTTPS
- [x] Separate challenge route management from individual certificate provisioning - HTTP/1.1 and HTTP/2 protocol handling
- [x] Update `provisionAcmeCertificate()` to not add/remove challenge routes - HTTP request/response parsing
- [x] Modify `provisionAllCertificates()` to handle challenge route lifecycle - HTTP to HTTPS redirects
- [x] Add error handling for challenge route initialization failures - ACME challenge handling
- Static route handlers
- WebSocket protocol upgrades
- Connection pooling for backend servers
- Certificate management (ACME and static)
#### Phase 3: Implement Concurrency Controls ### SmartProxy
3. **Add synchronization mechanisms** **Purpose**: Low-level connection router and port manager
- [x] Implement mutex/lock for challenge route operations
- [x] Ensure certificate provisioning is properly serialized
- [x] Add safeguards against duplicate challenge routes
- [x] Handle edge cases (shutdown during provisioning, renewal conflicts)
#### Phase 4: Enhance Error Handling **Responsibilities**:
4. **Improve error handling and recovery** - Port management (listen on multiple ports)
- [x] Add specific error types for port conflicts - Route-based connection routing
- [x] Implement retry logic for transient port binding issues - TLS passthrough (SNI-based routing)
- [x] Add detailed logging for challenge route lifecycle - NFTables integration
- [x] Ensure proper cleanup on errors - Delegate HTTP/HTTPS connections to HttpProxy
- Raw TCP proxying
- Connection lifecycle management
#### Phase 5: Create Comprehensive Tests ## Implementation Plan
5. **Write tests for challenge route management**
- [x] Test concurrent certificate provisioning
- [x] Test challenge route persistence during provisioning
- [x] Test error scenarios (port already in use)
- [x] Test cleanup after provisioning
- [x] Test renewal scenarios with existing challenge routes
#### Phase 6: Update Documentation ### Phase 1: Rename and Reorganize NetworkProxy ✅
6. **Document the new behavior**
- [x] Update certificate management documentation
- [x] Add troubleshooting guide for port conflicts
- [x] Document the challenge route lifecycle
- [x] Include examples of proper ACME configuration
### Technical Details 1. **Rename NetworkProxy to HttpProxy**
- Renamed directory from `network-proxy` to `http-proxy`
- Updated all imports and references
#### Specific Code Changes 2. **Update class and file names**
- Renamed `network-proxy.ts` to `http-proxy.ts`
- Updated `NetworkProxy` class to `HttpProxy` class
- Updated all type definitions and interfaces
1. In `SmartCertManager.initialize()`: 3. **Update exports**
- Updated exports in `ts/index.ts`
- Fixed imports across the codebase
### Phase 2: Extract HTTP Logic from SmartProxy ✅
1. **Create HTTP handler modules in HttpProxy**
- Created handlers directory with:
- `redirect-handler.ts` - HTTP redirect logic
- `static-handler.ts` - Static/ACME route handling
- `index.ts` - Module exports
2. **Move HTTP parsing from RouteConnectionHandler**
- Updated `handleRedirectAction` to delegate to `RedirectHandler`
- Updated `handleStaticAction` to delegate to `StaticHandler`
- Removed duplicated HTTP parsing logic
3. **Clean up references and naming**
- Updated all NetworkProxy references to HttpProxy
- Renamed config properties: `useNetworkProxy` → `useHttpProxy`
- Renamed config properties: `networkProxyPort` → `httpProxyPort`
- Fixed HttpProxyBridge methods and references
### Phase 3: Simplify SmartProxy
1. **Update RouteConnectionHandler**
- Remove embedded HTTP parsing
- Delegate HTTP routes to HttpProxy
- Focus on connection routing only
2. **Simplified route handling**
```typescript ```typescript
// Add challenge route once at initialization // Simplified handleRedirectAction
if (hasAcmeRoutes && this.acmeOptions?.email) { private handleRedirectAction(socket, record, route) {
await this.addChallengeRoute(); // Delegate to HttpProxy
this.httpProxy.handleRedirect(socket, route);
}
// Simplified handleStaticAction
private handleStaticAction(socket, record, route) {
// Delegate to HttpProxy
this.httpProxy.handleStatic(socket, route);
} }
``` ```
2. Modify `provisionAcmeCertificate()`: 3. **Update NetworkProxyBridge**
```typescript - Rename to HttpProxyBridge
// Remove these lines: - Update integration points
// await this.addChallengeRoute();
// await this.removeChallengeRoute();
```
3. Update `stop()` method: ### Phase 4: Consolidate HTTP Utilities ✅
```typescript
// Always remove challenge route on shutdown
if (this.challengeRoute) {
await this.removeChallengeRoute();
}
```
4. Add concurrency control: 1. **Move HTTP types to http-proxy**
```typescript - Created consolidated `http-types.ts` in `ts/proxies/http-proxy/models/`
private challengeRouteLock = new AsyncLock(); - Includes HTTP status codes, error classes, and interfaces
- Added helper functions like `getStatusText()`
private async manageChallengeRoute(operation: 'add' | 'remove'): Promise<void> { 2. **Clean up ts/http directory**
await this.challengeRouteLock.acquire('challenge-route', async () => { - Kept only router functionality
if (operation === 'add') { - Replaced local HTTP types with re-exports from HttpProxy
await this.addChallengeRoute(); - Updated imports throughout the codebase to use consolidated types
} else {
await this.removeChallengeRoute();
}
});
}
```
### Success Criteria ### Phase 5: Update Tests and Documentation ✅
- [x] No EADDRINUSE errors when provisioning multiple certificates
- [x] Challenge route remains active during entire provisioning cycle
- [x] Port 80 is only bound once per SmartProxy instance
- [x] Proper cleanup on shutdown or error
- [x] All tests pass
- [x] Documentation clearly explains the behavior
### Implementation Summary 1. **Update test files**
- Renamed NetworkProxy references to HttpProxy
- Renamed test files to match new naming
- Updated imports and references throughout tests
- Fixed certificate manager method names
The port 80 EADDRINUSE issue has been successfully fixed through the following changes: 2. **Update documentation**
- Updated README to reflect HttpProxy naming
- Updated architecture descriptions
- Updated usage examples
- Fixed all API documentation references
1. **Challenge Route Lifecycle**: Modified to add challenge route once during initialization and keep it active throughout certificate provisioning ## Migration Steps
2. **Concurrency Control**: Added flags to prevent concurrent provisioning and duplicate challenge route operations
3. **Error Handling**: Enhanced error messages for port conflicts and proper cleanup on errors
4. **Tests**: Created comprehensive test suite for challenge route lifecycle scenarios
5. **Documentation**: Updated certificate management guide with troubleshooting section for port conflicts
The fix ensures that port 80 is only bound once, preventing EADDRINUSE errors during concurrent certificate provisioning operations. 1. Create feature branch: `refactor/http-proxy-consolidation`
2. Phase 1: Rename NetworkProxy (1 day)
3. Phase 2: Extract HTTP logic (2 days)
4. Phase 3: Simplify SmartProxy (1 day)
5. Phase 4: Consolidate utilities (1 day)
6. Phase 5: Update tests/docs (1 day)
7. Integration testing (1 day)
8. Code review and merge
### Timeline ## Benefits
- Phase 1: 2 hours (Challenge route lifecycle)
- Phase 2: 1 hour (Provisioning flow)
- Phase 3: 2 hours (Concurrency controls)
- Phase 4: 1 hour (Error handling)
- Phase 5: 2 hours (Testing)
- Phase 6: 1 hour (Documentation)
Total estimated time: 9 hours 1. **Clear Separation**: HTTP/HTTPS handling is clearly separated from TCP routing
2. **Better Naming**: HttpProxy clearly indicates its purpose
3. **No Duplication**: HTTP parsing logic exists in one place
4. **Maintainability**: Easier to modify HTTP handling without affecting routing
5. **Testability**: Each component has a single responsibility
6. **Performance**: Optimized paths for different traffic types
### Notes ## Future Enhancements
- This is a critical bug affecting ACME certificate provisioning
- The fix requires careful handling of concurrent operations
- Backward compatibility must be maintained
- Consider impact on renewal operations and edge cases
## NEW FINDINGS: Additional Port Management Issues After this refactoring, we can more easily add:
### Problem Statement 1. HTTP/3 (QUIC) support in HttpProxy
Further investigation has revealed additional issues beyond the initial port 80 EADDRINUSE error: 2. Advanced HTTP features (compression, caching)
3. HTTP middleware system
4. Protocol-specific optimizations
5. Better HTTP/2 multiplexing
1. **Race Condition in updateRoutes**: Certificate manager is recreated during route updates, potentially causing duplicate challenge routes ## Breaking Changes
2. **Lost State**: The `challengeRouteActive` flag is not persisted when certificate manager is recreated
3. **No Global Synchronization**: Multiple concurrent route updates can create conflicting certificate managers
4. **Incomplete Cleanup**: Challenge route removal doesn't verify actual port release
### Implementation Plan for Additional Fixes 1. `NetworkProxy` class renamed to `HttpProxy`
2. Import paths change from `network-proxy` to `http-proxy`
3. Some type names may change for consistency
#### Phase 1: Fix updateRoutes Race Condition ## Rollback Plan
1. **Preserve certificate manager state during route updates**
- [x] Track active challenge routes at SmartProxy level
- [x] Pass existing state to new certificate manager instances
- [x] Ensure challenge route is only added once across recreations
- [x] Add proper cleanup before recreation
#### Phase 2: Implement Global Route Update Lock If issues arise:
2. **Add synchronization for route updates** 1. Git revert to previous commit
- [x] Implement mutex/semaphore for `updateRoutes` method 2. Re-deploy previous version
- [x] Prevent concurrent certificate manager recreations 3. Document lessons learned
- [x] Ensure atomic route updates 4. Plan incremental changes
- [x] Add timeout handling for locks
#### Phase 3: Improve State Management
3. **Persist critical state across certificate manager instances**
- [x] Create global state store for ACME operations
- [x] Track active challenge routes globally
- [x] Maintain port allocation state
- [x] Add state recovery mechanisms
#### Phase 4: Enhance Cleanup Verification
4. **Verify resource cleanup before recreation**
- [x] Wait for old certificate manager to fully stop
- [x] Verify challenge route removal from port manager
- [x] Add cleanup confirmation callbacks
- [x] Implement rollback on cleanup failure
#### Phase 5: Add Comprehensive Testing
5. **Test race conditions and edge cases**
- [x] Test rapid route updates with ACME
- [x] Test concurrent certificate manager operations
- [x] Test state persistence across recreations
- [x] Test cleanup verification logic
### Technical Implementation
1. **Global Challenge Route Tracker**:
```typescript
class SmartProxy {
private globalChallengeRouteActive = false;
private routeUpdateLock = new Mutex();
async updateRoutes(newRoutes: IRouteConfig[]): Promise<void> {
await this.routeUpdateLock.runExclusive(async () => {
// Update logic here
});
}
}
```
2. **State Preservation**:
```typescript
if (this.certManager) {
const state = {
challengeRouteActive: this.globalChallengeRouteActive,
acmeOptions: this.certManager.getAcmeOptions(),
// ... other state
};
await this.certManager.stop();
await this.verifyChallengeRouteRemoved();
this.certManager = await this.createCertificateManager(
newRoutes,
'./certs',
state
);
}
```
3. **Cleanup Verification**:
```typescript
private async verifyChallengeRouteRemoved(): Promise<void> {
const maxRetries = 10;
for (let i = 0; i < maxRetries; i++) {
if (!this.portManager.isListening(80)) {
return;
}
await this.sleep(100);
}
throw new Error('Failed to verify challenge route removal');
}
```
### Success Criteria
- [ ] No race conditions during route updates
- [ ] State properly preserved across certificate manager recreations
- [ ] No duplicate challenge routes
- [ ] Clean resource management
- [ ] All edge cases handled gracefully
### Timeline for Additional Fixes
- Phase 1: 3 hours (Race condition fix)
- Phase 2: 2 hours (Global synchronization)
- Phase 3: 2 hours (State management)
- Phase 4: 2 hours (Cleanup verification)
- Phase 5: 3 hours (Testing)
Total estimated time: 12 hours
### Priority
These additional fixes are HIGH PRIORITY as they address fundamental issues that could cause:
- Port binding errors
- Certificate provisioning failures
- Resource leaks
- Inconsistent proxy state
The fixes should be implemented immediately after the initial port 80 EADDRINUSE fix is deployed.
### Implementation Complete
All additional port management issues have been successfully addressed:
1. **Mutex Implementation**: Created a custom `Mutex` class for synchronizing route updates
2. **Global State Tracking**: Implemented `AcmeStateManager` to track challenge routes globally
3. **State Preservation**: Modified `SmartCertManager` to accept and preserve state across recreations
4. **Cleanup Verification**: Added `verifyChallengeRouteRemoved` method to ensure proper cleanup
5. **Comprehensive Testing**: Created test suites for race conditions and state management
The implementation ensures:
- No concurrent route updates can create conflicting states
- Challenge route state is preserved across certificate manager recreations
- Port 80 is properly managed without EADDRINUSE errors
- All resources are cleaned up properly during shutdown
All tests are ready to run and the implementation is complete.
