The code demonstrates the HTTP/3 protocol stack, including QUIC transport, QPACK header compression, and proper frame handling. + +## Strengths + +1. **MISRA Compliance**: Excellent adherence to MISRA C++ guidelines with proper use of: + - Strong typing with enum classes + - Explicit constructors + - `constexpr` for compile-time evaluation + - No dynamic memory allocation + - Bounds checking + +2. **Protocol Implementation**: + - Proper HTTP/3 frame types (DATA, HEADERS, SETTINGS, etc.) + - QPACK static/dynamic tables for header compression + - Stream management with correct client-initiated stream IDs + - Alt-Svc support for HTTP/3 discovery + +3. **Safety Features**: + - Comprehensive error handling with Result enum + - Buffer overflow protection + - Input validation (hostname, parameters) + - No use of raw pointers where possible + +## Areas for Enhancement + +### 1. QPACK Implementation +The current QPACK encoder/decoder is simplified. For production use, consider: +- Huffman encoding for string literals +- Dynamic table updates and eviction +- Proper handling of indexed header fields with name reference + +### 2. QUIC Transport Layer +The TODO comments indicate missing QUIC implementation: +```cpp +// Real QUIC packet creation would include: +- Packet header with connection ID and packet number +- CRYPTO frames for TLS handshake +- STREAM frames for application data +- ACK frames for reliability +- Flow control with MAX_DATA/MAX_STREAM_DATA frames +``` + +### 3. Connection Migration +HTTP/3 supports connection migration. Consider adding: +```cpp +struct ConnectionMigration { + std::array new_connection_id{}; + std::uint64_t retire_prior_to{0U}; + bool path_validation_required{false}; +}; +``` + +### 4. Priority and Push +HTTP/3 extensible priorities could be added: +```cpp +struct Priority { + std::uint8_t urgency{3U}; // 0-7, default 3 + bool incremental{false}; +}; +``` + +### 5. Error Recovery +Consider implementing: +- Retry packets for connection establishment +- Stateless reset tokens +- Path validation for connection migration + +## Potential Improvements + +### 1. Variable-Length Integer Encoding +HTTP/3 uses QUIC variable-length integers: +```cpp +[[nodiscard]] constexpr Result encode_varint( + std::uint64_t value, + std::uint8_t* output, + std::size_t& encoded_length) noexcept { + + if (value < 64U) { + output[0] = static_cast(value); + encoded_length = 1U; + } else if (value < 16384U) { + output[0] = static_cast((value >> 8U) | 0x40U); + output[1] = static_cast(value & 0xFFU); + encoded_length = 2U; + } else if (value < 1073741824U) { + // 4-byte encoding + encoded_length = 4U; + } else { + // 8-byte encoding + encoded_length = 8U; + } + return Result::Success; +} +``` + +### 2. Congestion Control +Add basic congestion control state: +```cpp +struct CongestionControl { + std::uint64_t congestion_window{14720U}; // Initial window + std::uint64_t bytes_in_flight{0U}; + std::uint32_t smoothed_rtt{0U}; + std::uint32_t rtt_variance{0U}; +}; +``` + +### 3. TLS Integration +For actual QUIC handshake: +```cpp +struct TlsState { + std::array client_random{}; + std::array handshake_secret{}; + std::array application_secret{}; + bool handshake_confirmed{false}; +}; +``` + +## Testing Considerations + +For production deployment, consider: +1. **Interoperability testing** with existing HTTP/3 servers (nginx-quic, Cloudflare) +2. **Packet loss simulation** to test retransmission logic +3. **Performance testing** under various network conditions +4. **Security testing** for amplification attacks and handshake vulnerabilities + +The foundation you've built is solid and demonstrates excellent understanding of both embedded programming constraints and modern web protocols. The modular design makes it straightforward to add the missing QUIC transport layer components when needed. diff --git a/nonHosted/http3Client/http3_client.hpp b/nonHosted/http3Client/http3_client.hpp new file mode 100644 index 0000000..073896c --- /dev/null +++ b/nonHosted/http3Client/http3_client.hpp @@ -0,0 +1,1075 @@ +#pragma once + +#include +#include +#include +#include +#include +#include + +// Complete MISRA C++17 compliant HTTP/3 client with QPACK and frame handling +namespace http3 { + +// MISRA-compliant error handling +enum class Result : std::uint8_t { + Success = 0, + InvalidParameter = 1, + ConnectionFailed = 2, + BufferOverflow = 3, + Timeout = 4, + ProtocolError = 5, + CryptoError = 6, + FlowControlError = 7, + JsonError = 8, + NetworkError = 9, + ServerError = 10, + QpackError = 11, + FrameError = 12, + StreamError = 13 +};
