-## Upgrading from 1.1.0 to 1.2.0 - -Version 1.2.0 contains **BREAKING CHANGES** to improve fault-tolerance and ensure the HTTP server cannot crash your application. - -### Critical Changes - -#### 1. Server::start() now returns bool - -**Before (1.1.0):** -```php -$server = new Server($config); -$server->start(); // Could throw exception and crash application -``` - -**After (1.2.0):** -```php -$server = new Server($config); -if (!$server->start()) { - // Server failed to start, but application continues running - $logger->warning('HTTP server failed to start', [ - 'reason' => 'Port already in use or SSL configuration error' - ]); - // You can continue without HTTP, try again later, or take other actions -} -``` - -**Why?** In Duyler Framework, the HTTP server runs inside your Event Bus worker. If `start()` throws an exception, it kills the entire application. Now the application can handle server startup failures gracefully. - -#### 2. Server::getRequest() now returns nullable - -**Before (1.1.0):** -```php -if ($server->hasRequest()) { - $request = $server->getRequest(); // Could throw on race conditions - $response = handleRequest($request); - $server->respond($response); -} -``` - -**After (1.2.0):** -```php -if ($server->hasRequest()) { - $request = $server->getRequest(); - - if ($request === null) { - // Request was consumed by timeout, error, or race condition - continue; - } - - $response = handleRequest($request); - $server->respond($response); -} -``` - -**Why?** Race conditions between `hasRequest()` and `getRequest()` could crash the application. Now errors are handled gracefully. - -#### 3. Server::hasRequest() never throws - -**Before (1.1.0):** -```php -// Could throw HttpServerException if server not running -if ($server->hasRequest()) { - // ... -} -``` - -**After (1.2.0):** -```php -// Always safe - returns false on any error -if ($server->hasRequest()) { - // ... -} -``` - -**Why?** Complete isolation.

No breaking changes to the public API. - -### What's New - -#### 1. Graceful Shutdown - -```php -use Duyler\HttpServer\Server; -use Duyler\HttpServer\Config\ServerConfig; - -$server = new Server(new ServerConfig()); -$server->start(); - -// Graceful shutdown with 30 second timeout -$success = $server->shutdown(30); -``` - -#### 2. Rate Limiting - -```php -$config = new ServerConfig( - enableRateLimit: true, - rateLimitRequests: 100, // Max 100 requests - rateLimitWindow: 60, // Per 60 seconds -); - -$server = new Server($config); -``` - -#### 3. Server Metrics - -```php -$server = new Server(new ServerConfig()); -$server->start(); - -// Get metrics -$metrics = $server->getMetrics(); -// [ -// 'uptime_seconds' => 3600, -// 'total_requests' => 10000, -// 'successful_requests' => 9850, -// 'failed_requests' => 150, -// 'active_connections' => 5, -// 'cache_hit_rate' => 85.5, -// 'avg_request_duration_ms' => 12.3, -// 'requests_per_second' => 2.78, -// ... -// ] -``` - -#### 4. Accept Limit Configuration - -```php -$config = new ServerConfig( - maxAcceptsPerCycle: 10, // Accept max 10 connections per cycle -); -``` - -### Behavioral Changes - -#### Static File Handling - -**Before 1.1.0:** -- Large files loaded entirely into memory -- Could cause OOM errors - -**After 1.1.0:** -- Large files streamed directly from disk -- LRU cache eviction prevents memory issues -- Configurable file count limit - -No code changes required - works automatically. - -#### Multipart File Uploads - -**Before 1.1.0:** -- Temporary files might not be cleaned up -- Potential memory leaks - -**After 1.1.0:** -- Automatic cleanup on server reset -- `TempFileManager` handles all temp files -- No memory leaks - -No code changes required - works automatically. - -#### Error Handling - -**Before 1.1.0:** -- Some errors suppressed with `@` operator -- Hard to debug socket issues - -**After 1.1.0:** -- All errors explicitly handled -- Better error messages -- Easier debugging - -No code changes required - better error visibility. - -### New Configuration Options - -```php -$config = new ServerConfig( - // Rate limiting (new in 1.1.0) - enableRateLimit: false, - rateLimitRequests: 100, - rateLimitWindow: 60, - - // Accept limit (new in 1.1.0) - maxAcceptsPerCycle: 10, - - // Existing options (unchanged) - host: '0.0.0.0', - port: 8080, - maxConnections: 1000, - requestTimeout: 30, - connectionTimeout: 60, - maxRequestSize: 10485760, - bufferSize: 8192, - enableKeepAlive: true, - keepAliveTimeout: 30, - keepAliveMaxRequests: 100, - enableStaticCache: true, - staticCacheSize: 52428800, - debugMode: false, -); -``` - -### Security Improvements - -#### 1. HTTP Request Smuggling Protection - -Automatic - no code changes needed. Server now rejects requests with duplicate headers. - -#### 2. Multipart Boundary Validation - -Automatic - no code changes needed. Server validates boundaries according to RFC 2046. - -#### 3. Rate Limiting - -Enable in configuration: - -```php -$config = new ServerConfig( - enableRateLimit: true, - rateLimitRequests: 100, - rateLimitWindow: 60, -); -``` - -### Performance Improvements - -All performance improvements are automatic: - -- **Socket Writing**: Buffered writes reduce syscalls -- **Response Building**: Optimized string operations -- **Static Files**: Large files streamed efficiently -- **Cache**: LRU eviction prevents memory bloat - -Expected improvements: -- 20-30% reduction in memory usage for static files -- 15-20% faster response writing for large responses -- Better CPU utilization under high load - -### Testing - -Run your existing test suite - no changes needed: - -```bash -./vendor/bin/phpunit -``` - -All 1.0.0 tests should pass without modifications. - -### Compatibility - -- **PHP Version**: Still requires PHP 8.4+ -- **Dependencies**: Same as 1.0.0 -- **API**: Fully backward compatible -- **Configuration**: All 1.0.0 configs work in 1.1.0 - -### Recommended Actions - -1. **Update composer.json**: - ```json - { - "require": { - "duyler/http-server": "^1.1" - } - } - ``` - -2. **Run composer update**: - ```bash - composer update duyler/http-server - ``` - -3. **Run tests**: - ```bash - ./vendor/bin/phpunit - ``` - -4. **Consider enabling rate limiting** for production: - ```php - $config = new ServerConfig( - enableRateLimit: true, - rateLimitRequests: 1000, - rateLimitWindow: 60, - ); - ``` - -5. **Monitor metrics** in production: - ```php - // Periodically log metrics - $metrics = $server->getMetrics(); - $logger->info('Server metrics', $metrics); - ``` - -### Troubleshooting - -#### Issue: "Too Many Requests" errors - -If you see 429 errors after upgrade, rate limiting might be too strict: - -```php -// Increase limits -$config = new ServerConfig( - enableRateLimit: true, - rateLimitRequests: 1000, // Increase from 100 - rateLimitWindow: 60, -); -``` - -Or disable temporarily: - -```php -$config = new ServerConfig( - enableRateLimit: false, -); -``` - -#### Issue: Connection warnings in tests - -Socket bind warnings in tests are expected for error cases.
