# Port 80 ACME Management in SmartProxy
## Overview
SmartProxy correctly handles port management when both user routes and ACME challenges need to use the same port (typically port 80). This document explains how the system prevents port conflicts and EADDRINUSE errors.
## Port Deduplication
SmartProxy's PortManager implements automatic port deduplication:
```typescript
public async addPort(port: number): Promise<void> {
// Check if we're already listening on this port
if (this.servers.has(port)) {
console.log(`PortManager: Already listening on port ${port}`);
return;
}
// Create server for this port...
}
```
This means that when both a user route and ACME challenges are configured to use port 80, the port is only opened once and shared between both use cases.
## ACME Challenge Route Flow
1. **Initialization**: When SmartProxy starts and detects routes with `certificate: 'auto'`, it initializes the certificate manager
2. **Challenge Route Creation**: The certificate manager creates a special challenge route on the configured ACME port (default 80)
3. **Route Update**: The challenge route is added via `updateRoutes()`, which triggers port allocation
4. **Deduplication**: If port 80 is already in use by a user route, the PortManager's deduplication prevents double allocation
5. **Shared Access**: Both user routes and ACME challenges share the same port listener
## Configuration Examples
### Shared Port (Recommended)
```typescript
const settings = {
routes: [
{
name: 'web-traffic',
match: {
ports: [80]
},
action: {
type: 'forward',
targetUrl: 'http://localhost:3000'
}
},
{
name: 'secure-traffic',
match: {
ports: [443]
},
action: {
type: 'forward',
targetUrl: 'https://localhost:3001',
tls: {
mode: 'terminate',
certificate: 'auto'
}
}
}
],
acme: {
email: 'your-email@example.com',
port: 80 // Same as user route - this is safe!
}
};
```
### Separate ACME Port
```typescript
const settings = {
routes: [
{
name: 'web-traffic',
match: {
ports: [80]
},
action: {
type: 'forward',
targetUrl: 'http://localhost:3000'
}
}
],
acme: {
email: 'your-email@example.com',
port: 8080 // Different port for ACME challenges
}
};
```
## Best Practices
1. **Use Default Port 80**: Let ACME use port 80 (the default) even if you have user routes on that port
2. **Priority Routing**: ACME challenge routes have high priority (1000) to ensure they take precedence
3. **Path-Based Routing**: ACME routes only match `/.well-known/acme-challenge/*` paths, avoiding conflicts
4. **Automatic Cleanup**: Challenge routes are automatically removed when not needed
## Troubleshooting
### EADDRINUSE Errors
If you see EADDRINUSE errors, check:
1. Is another process using the port?
2. Are you running multiple SmartProxy instances?
3. Is the previous instance still shutting down?
### Certificate Provisioning Issues
1. Ensure the ACME port is accessible from the internet
2. Check that DNS is properly configured for your domains
3. Verify email configuration in ACME settings
## Technical Details
The port deduplication is handled at multiple levels:
1. **PortManager Level**: Checks if port is already active before creating new listener
2. **RouteManager Level**: Tracks which ports are needed and updates accordingly
3. **Certificate Manager Level**: Adds challenge route only when needed
This multi-level approach ensures robust port management without conflicts.

## NEW FINDINGS: Additional Port Management Issues
### Problem Statement
Further investigation has revealed additional issues beyond the initial port 80 EADDRINUSE error:
1. **Race Condition in updateRoutes**: Certificate manager is recreated during route updates, potentially causing duplicate challenge routes
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
#### Phase 1: Fix updateRoutes Race Condition
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
2. **Add synchronization for route updates**
- [x] Implement mutex/semaphore for `updateRoutes` method
- [x] Prevent concurrent certificate manager recreations
- [x] Ensure atomic route updates
- [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.
