Http Parser
http-parser is a C-based library for extracting request and response metadata from raw HTTP data streams. It utilizes a state-machine approach to identify message segments and boundaries.
The project implements zero-copy string parsing and pointer-based URL deconstruction to avoid memory allocations and data duplication. It supports incremental stream processing to handle fragmented data chunks and includes mechanisms for decoding chunked encoding and managing network protocol upgrades.
Features
- State-Machine Parsers - Utilizes a state-machine parser to sequentially process byte streams and identify HTTP boundaries.
- Zero-Copy Parsing - Extracts metadata by returning pointers to the original input buffer, avoiding new memory allocations.
- Incremental Stream Processing - Processes fragmented data chunks sequentially to assemble payloads without loading everything into memory.
- Request Parsing - Converts raw socket byte streams into structured HTTP request and response metadata.
- Incremental Body Processing - Processes fragmented HTTP response bodies in chunks to minimize memory overhead.
- URL Component Deconstructors - Splits URLs into constituent parts using pointer offsets to avoid memory duplication.
- URL Data Parsing - Provides high-performance URL parsing that avoids memory copies to maintain low overhead.
- Chunked Transfer Encoding - Decodes HTTP transfer-encoded data streams to deliver a fully assembled response body.
- Event-Driven Callbacks - Implements an event-driven callback system to notify consumers as HTTP message segments are identified.
- Response Body Decoders - Decodes chunked HTTP response payloads into a continuous data stream.
- Protocol Upgrades - Provides mechanisms to track the exact byte offset for transitioning HTTP connections to new protocols.
- Networking - HTTP request/response parser.
- Build Systems - A lightweight parser for HTTP request and response messages.
- Networking Libraries - HTTP request and response parsing.
