Http Parser
http-parser est une bibliothèque C conçue pour l'analyse de messages HTTP en mode zero-copy, la déconstruction d'URL et la gestion des mises à niveau de protocole et de l'encodage par blocs (chunked encoding). Elle fournit des utilitaires pour extraire les en-têtes, les méthodes et les codes de statut des requêtes et réponses HTTP.
Le projet inclut un analyseur d'URL zero-copy pour décomposer les chaînes en composants individuels et un mécanisme de détection des requêtes de changement de protocole pour identifier l'offset exact où commencent les données non-HTTP. Il dispose également d'un décodeur pour gérer les flux de données encodés en transfert par blocs.
Features
- Message Parsing - Implements a zero-copy approach to extract header fields, status codes, and methods from HTTP requests and responses.
- Zero-Copy Parsing - Extracts data from input buffers by referencing pointers to the original memory instead of allocating new tokens.
- Chunked Transfer Encoding - Decodes data streams using chunked transfer encoding to retrieve the final response body.
- HTTP Message Parsers - Provides a C library for extracting headers, methods, and status codes using a high-performance zero-copy approach.
- URL Parsers - Offers a high-performance utility for deconstructing URL strings into individual components without memory allocation.
- Incremental Stream Processing - Processes incoming HTTP data incrementally in small chunks to avoid loading entire requests into memory.
- State-Based Parsing - Uses a state-machine based parsing technique to track context and handle byte streams incrementally.
- URL Component Deconstructors - Splits complex URL strings into constituent parts such as host, path, and query parameters.
- URL Data Parsing - Converts raw URL strings into structured components using a zero-copy utility.
- HTTP Upgrade Handlers - Handles the conversion of inbound HTTP requests into persistent connections by detecting protocol upgrade requests.
- Stream Offset Tracking - Tracks the exact byte position within the message stream to identify where protocol transitions occur.
- C Memory Management - Implements low-level memory allocation and cleanup for buffers within a C-based library to minimize overhead.
- Protocol Upgrades - Detects requests to switch protocols and identifies the byte offset where the new protocol stream begins.
- Development Utilities - C-based HTTP request/response parser.
