We will avoid external networking libraries like Boost.Asio or libuv for the core socket operations, as requested. +2. **Asynchronous Operations:** All network operations (connect, accept, read, write, DNS lookup, TLS handshake) must be non-blocking. Completion, data availability, or errors should be signaled asynchronously, likely via signals/slots or callback mechanisms that integrate naturally with the KDFoundation event loop. +3. **Modern C++:** Utilize features like RAII (for socket/resource management), `std::function` or similar for callbacks, `std::error_code` or custom error types, and potentially C++17/20 features where appropriate for cleaner and safer code. + +## Proposed Implementation Plan + +1. **URI Handling (`KDUtils::Url`)** + + - **Status:** Already exists (`/src/KDUtils/url.h`). + - **Action:** Use `KDUtils::Url` for parsing and constructing URIs needed for HTTP requests and potentially other protocols. Ensure it provides easy access to scheme, host, port, path, etc., as needed by the networking components. + +2. **Asynchronous Socket Base (`KDFoundation::Net::Socket` or similar)** + + - **Responsibility:** Manage the raw BSD socket file descriptor and its integration with the event loop. + - **Features:** + - Methods: `open()`, `close()`, `bind()`, `setBlocking(false)`. + - RAII: Constructor acquires the socket FD, destructor closes it. Consider move semantics. + - **Event Loop Integration:** Internally create and manage `KDFoundation::FileDescriptorNotifier` instances to monitor the socket FD for readability and writability. When the notifier signals, emit corresponding signals/callbacks (e.g., `readyRead()`, `bytesWritten()`, `errorOccurred(ErrorCode)`). + - **Error Handling:** Define and use a consistent error reporting mechanism (e.g., `std::error_code`, custom enum/class) that can represent socket-level errors (`errno`) and potentially higher-level issues. + +3. **TCP Client (`KDFoundation::Net::TcpSocket`)** + + - **Responsibility:** Handle client-side TCP connections. Could inherit from or compose the base `Socket`. + - **Features:** + - `connectToHost(host, port)`: Initiates a non-blocking connection. Monitor the socket FD for writability (signals connection success) or error using the `FileDescriptorNotifier`. + - Signals/Callbacks: `connected()`, `disconnected()`, `errorOccurred(ErrorCode)`, `readyRead()`, `bytesWritten(count)`. These are triggered by the underlying event loop integration. + - `read(buffer, maxSize)` / `readAll()`: Reads available data _after_ the `readyRead()` signal is emitted. Returns data read or indicates errors. Non-blocking. + - `write(data)`: Attempts to write data. Returns bytes written immediately or 0/-1 if the socket isn't ready (EWOULDBLOCK/EAGAIN). Use the `bytesWritten` signal (triggered when the notifier signals writability) to manage buffering and report completion. Non-blocking. + +4. **TCP Server (`KDFoundation::Net::TcpServer`)** + + - **Responsibility:** Listen for and accept incoming TCP connections. + - **Features:** + - Uses a base `Socket` internally for the listening socket. + - `listen(address, port)`: Binds and starts listening. Uses `FileDescriptorNotifier` on the listening socket, monitoring for readability. + - Signal/Callback: `newConnection(std::unique_ptr)`. Triggered when the `FileDescriptorNotifier` indicates the listening socket is readable (signaling a pending connection). + - Internal Logic: When notified, call `accept()` to get the new client socket FD, create a new `Net::TcpSocket` instance (transferring FD ownership, perhaps via move semantics), and emit the `newConnection` signal with the new socket object. + +5. **UDP Sockets (`KDFoundation::Net::UdpSocket`)** + + - **Responsibility:** Handle UDP datagram sending and receiving. + - **Features:** + - Uses a base `Socket` internally. + - `bind(address, port)`: Binds the socket for receiving. Uses `FileDescriptorNotifier` for readability. + - `writeDatagram(data, host, port)`: Sends a datagram using `sendto()`. Non-blocking. + - `readDatagram(buffer, maxSize, &senderHost, &senderPort)`: Called after `readyRead()` signal to receive data using `recvfrom()`. + - Signals/Callbacks: `readyRead(senderHost, senderPort)`, `errorOccurred(ErrorCode)`. `readyRead` should probably include sender info. + +6. **Asynchronous DNS Lookups (`KDFoundation::Net::DnsResolver`)** + + - **Challenge:** Standard `getaddrinfo` is blocking. + - **Options:** + - **Thread Pool:** Execute blocking `getaddrinfo` in a separate KDFoundation thread (if threading is available/suitable) and post the results back to the main event loop via signals/events. This is often the simplest cross-platform approach if a dedicated async library isn't used. + - **c-ares Library:** Integrate the `c-ares` C library. It's specifically designed for asynchronous DNS and can integrate with external event loops by providing file descriptors and timeouts to monitor via `FileDescriptorNotifier` and KDFoundation timers. More complex but potentially higher performance. + - **Interface:** Define a `Net::DnsResolver` class. A method like `lookup(hostname)` should return a future/promise or take a callback, which is invoked asynchronously from the event loop with the list of addresses or an error. + +7. **SSL/TLS Support (`KDFoundation::Net::SslSocket`, `KDFoundation::Net::SslServer`)** + + - **Dependency:** Link against libssl (OpenSSL). + - **Approach:** Wrap OpenSSL's non-blocking BIO or socket-level API. + - **Context:** Create `Net::SslContext` to manage `SSL_CTX` (loading certificates, keys, setting protocols/ciphers). + - **`Net::SslSocket`:** + - Wraps a `Net::TcpSocket`. + - Manages an `SSL*` object associated with the socket FD. + - Implements `connectToHostEncrypted()`, `readEncrypted()`, `writeEncrypted()`. + - **Integration:** Perform OpenSSL operations (`SSL_connect`, `SSL_accept`, `SSL_read`, `SSL_write`). When they return `SSL_ERROR_WANT_READ` or `SSL_ERROR_WANT_WRITE`, pause the operation and rely on the underlying `TcpSocket`'s `FileDescriptorNotifier` integration to signal when the socket is ready. Resume the OpenSSL operation when notified. + - Handles the asynchronous TLS handshake process using this mechanism. Signals like `encrypted()` can indicate handshake completion. + - **`Net::SslServer`:** Similar to `TcpServer`, but after accepting a raw TCP connection, it initiates the server-side TLS handshake (`SSL_accept`) asynchronously using the mechanism above, ultimately providing `Net::SslSocket` instances via a signal like `newEncryptedConnection`. + +8. **HTTP Client (`KDFoundation::Http::Client`)** + + - **Responsibility:** High-level HTTP/1.1 request execution. + - **Features:** + - Uses `Net::TcpSocket` or `Net::SslSocket` (determined by the `KDUtils::Url` scheme) and `Net::DnsResolver`. + - Input: Takes a `Http::Request` object (containing `KDUtils::Url`, method, headers, optional body). + - Process: Performs DNS lookup, connects (TCP/TLS), sends the formatted HTTP request headers and body, reads and parses the HTTP response (status line, headers, body). + - Output: Asynchronously returns a `Http::Response` object (or an error) via a future, promise, or callback. + - Considerations: Handle redirects, connection reuse (Keep-Alive), chunked transfer encoding. + +9. **Websocket Support (Future)** + - **Foundation:** The `Net::TcpSocket` and `Net::SslSocket` provide the necessary transport layer. + - **Implementation:** + - Perform the initial HTTP/S handshake using logic similar to the `Http::Client` to negotiate the protocol upgrade. + - Once upgraded, use the underlying `TcpSocket`/`SslSocket` directly to send/receive raw websocket frames according to RFC 6455. + - Implement websocket framing logic (parsing opcodes, masking client-to-server frames, handling fragmentation, pings/pongs) as a layer on top of the socket. + +This structured approach should provide a solid foundation for adding powerful and convenient asynchronous networking capabilities to KDFoundation.

This is particularly useful for applications like the OpenAI API's streaming responses where results need to be delivered incrementally as they become available. + +Let me outline a plan for extending the KDNetwork library to support SSE: + +## 1. Create a Server Sent Events Client Class + +First, we should create a specialized client class for handling SSE connections:Based on my analysis of the codebase, here's a comprehensive plan for extending the KDNetwork library to support Server Sent Events (SSE): + +## 1. Create an SSE Client Class + +First, we should create a dedicated class to handle SSE connections. This class would extend the existing HttpClient functionality: + +```cpp +class SseClient { +public: + // Constructor accepting an HttpClient + explicit SseClient(std::shared_ptr httpClient = nullptr); + + // Connect to an SSE endpoint + void connect(const HttpRequest& request); + + // Disconnect from the current SSE stream + void disconnect(); + + // Signal emitted when a message is received + KDBindings::Signal messageReceived; + + // Signal emitted when the connection is established + KDBindings::Signal<> connected; + + // Signal emitted when the connection is closed + KDBindings::Signal<> disconnected; + + // Signal emitted when an error occurs + KDBindings::Signal error; +}; +``` + +## 2. Define an SSE Event Class + +Next, we need a class to represent SSE events: + +```cpp +class SseEvent { +public: + // The event ID (optional in SSE) + std::string id; + + // The event type (defaults to "message" if not specified) + std::string event; + + // The data payload + std::string data; + + // Retry timeout in milliseconds + std::optional retry; +}; +``` + +## 3. Extend HttpClient to Support SSE + +The HttpClient class would need modifications to: + +1. Support maintaining a persistent connection +2. Parse SSE-formatted responses +3. Emit events as they come in rather than waiting for the full response + +```cpp +// Add to HttpClient class: +public: + /** + * @brief Create a Server-Sent Events client + * @return A new SseClient instance using this HttpClient + */ + std::shared_ptr createSseClient(); + +private: + // Internal method for SSE connection handling + void setupSseConnection(std::shared_ptr state); + + // Parse incoming SSE data + void processSseData(std::shared_ptr state); +``` + +## 4. Add an SSE Parser + +Implement a parser to handle the SSE format according to the specification: + +```cpp +class SseParser { +public: + // Process incoming data chunk and return any complete events + std::vector processData(const KDUtils::ByteArray& data); + +private: + // Buffer for incomplete events + std::string m_buffer; + + // Parse a single event from text + SseEvent parseEvent(const std::string& eventText); +}; +``` + +## 5. Modify RequestState Class + +The existing `RequestState` class needs to be extended to handle SSE connections: + +```cpp +// Add to existing RequestState class: +bool sseMode = false; +SseParser sseParser; +std::function sseCallback; +``` + +## 6. Implement SSE-specific HTTP Request Handling + +We need to implement special handling for SSE requests: + +1. Set appropriate headers: + - `Accept: text/event-stream` + - `Cache-Control: no-cache` +2. Keep the connection open +3. Parse incoming chunks as they arrive + +## 7. Implementation Flow + +Here's how the SSE functionality would work: + +1. User creates an `HttpRequest` object specifying the SSE endpoint +2. User connects to the SSE endpoint using either: + - `SseClient::connect(request)` + - `HttpClient::send(request)` with a special flag or header +3. The `HttpClient` keeps the connection open +4. As data arrives, it's parsed using the `SseParser` +5. Complete SSE events are emitted via signals +6. The connection remains open until explicitly closed or an error occurs + +## 8. Example Usage + +```cpp +// Create an HTTP client +auto httpClient = std::make_shared(); + +// Create an SSE client +auto sseClient = httpClient->createSseClient(); + +// Connect to SSE endpoint +KDNetwork::HttpRequest request("https://api.openai.com/v1/completions"); +request.setMethod(KDNetwork::HttpMethod::Post); +request.setHeader("Content-Type", "application/json"); +request.setHeader("Authorization", "Bearer YOUR_API_KEY"); +request.setBody("{\"model\": \"gpt-3.5-turbo\", \"stream\": true, \"messages\": [{\"role\": \"user\", \"content\": \"Hello\"}]}"); + +// Handle events +std::ignore = sseClient->messageReceived.connect([](const KDNetwork::SseEvent& event) { + // Process each chunk as it arrives + std::cout << "Received: " << event.data << std::endl; +}); + +// Handle connection events +std::ignore = sseClient->connected.connect([]() { + std::cout << "Connected to SSE stream" << std::endl; +}); + +std::ignore = sseClient->disconnected.connect([]() { + std::cout << "Disconnected from SSE stream" << std::endl; +}); + +// Connect to the stream +sseClient->connect(request); +``` + +## 9. Technical Challenges and Solutions + +1. **Connection Management**: Keep-alive connections need to be maintained indefinitely. The connection pooling and cleanup mechanisms in HttpClient may need adjustments. + +2. **Chunked Transfer Encoding**: SSE typically uses chunked transfer encoding. The response parser needs to handle this correctly. + +3. **Handling Reconnection**: If the connection is lost, SSE clients should automatically reconnect with the last received event ID. + +4. **Event Parsing**: SSE has a specific format that needs careful parsing: + + ``` + event: event_type + id: event_id + data: event_data + retry: reconnection_time + + ``` + +5. **Timeouts**: Need to handle keep-alive timeouts and implement reconnection logic. + +## 10. Integration with Existing Architecture + +The implementation should leverage the existing event system in KDFoundation: + +1. Use `FileDescriptorNotifier` for socket readiness notifications +2. Leverage the existing event loop for async behavior +3. Utilize the signal mechanism from KDBindings for event notifications + +This approach maintains consistency with the rest of the library while adding the specialized SSE functionality. + +Would you like me to provide more details on any specific part of this implementation plan?

Implementation Details + +### HTTP Upgrade Process + +1.

Take ownership of the socket from the `HttpClient` +2. Set up read/write handlers for WebSocket frame processing +3. Manage the WebSocket connection lifecycle + +```cpp +void WebSocketClient::setupSocket(std::shared_ptr socket) { + m_socket = socket; + m_state = State::Connected; + + // Set up read handler + m_socket->readyRead.connect([this]() { + processIncomingData(); + }); + + m_socket->errorOccurred.connect([this](std::error_code ec) { + handleSocketError(ec); + }); + + // Start keep-alive timer for ping/pong + startPingTimer(); + + // Emit connected signal + connected.emit(); +} +``` + +### Frame Processing + +The WebSocket protocol requires proper frame parsing and generation: + +```cpp +void WebSocketClient::processIncomingData() { + // Read available data from socket + auto data = m_tcpSocket->readAll(); + + // Append to buffer + m_receiveBuffer.append(data); + + // Process frames in buffer + size_t bytesProcessed = 0; + while (m_receiveBuffer.size() > 2) { // Minimum frame size + auto frame = WebSocketFrame::decode(m_receiveBuffer, bytesProcessed); + + if (!frame.has_value()) { + // Need more data + break; + } + + // Handle the frame based on opcode + handleFrame(*frame); + + // Remove processed frame from buffer + m_receiveBuffer = m_receiveBuffer.mid(bytesProcessed); + } +} + +void WebSocketClient::handleFrame(const WebSocketFrame &frame) { + switch (frame.opCode()) { + case WebSocketFrame::OpCode::Text: + textMessageReceived.emit(frame.payload().toString()); + break; + + case WebSocketFrame::OpCode::Binary: + binaryMessageReceived.emit(frame.payload()); + break; + + case WebSocketFrame::OpCode::Close: + handleCloseFrame(frame); + break; + + case WebSocketFrame::OpCode::Ping: + // Automatically respond with pong + sendPong(frame.payload()); + break; + + case WebSocketFrame::OpCode::Pong: + m_lastPongReceived = std::chrono::steady_clock::now(); + pongReceived.emit(frame.payload()); + break; + + default: + // Unhandled opcode + break; + } +} +``` + +### Reconnection Logic + +To support automatic reconnection: + +```cpp +void WebSocketClient::handleSocketError(std::error_code ec) { + // Reset state + m_state = State::Closed; + + // Emit error + errorOccurred.emit("Socket error: " + ec.message()); + + // Attempt reconnect if enabled + if (m_autoReconnect && m_reconnectAttempts < m_maxReconnectAttempts) { + m_reconnectAttempts++; + aboutToReconnect.emit(); + + // Schedule reconnect + auto timer = std::make_shared(); + timer->setSingleShot(true); + timer->setInterval(m_reconnectInterval); + timer->timeout.connect([this, timer]() { + if (m_url.isValid()) { + connectToUrl(m_url); + } + }); + timer->start(); + } +} +``` + +## 4. Graceful Connection Handling + +To implement graceful disconnection: + +```cpp +void WebSocketClient::disconnect(uint16_t code, const std::string &reason) { + if (m_state == State::Connected) { + m_state = State::Closing; + + // Send close frame + auto closeFrame = WebSocketFrame::createCloseFrame(code, reason); + sendFrame(closeFrame); + + // Set up a timeout for clean disconnection + m_closeTimer = std::make_unique(); + m_closeTimer->setSingleShot(true); + m_closeTimer->setInterval(std::chrono::seconds(5)); + m_closeTimer->timeout.connect([this]() { + // Force close if no response + forceClose(); + }); + m_closeTimer->start(); + } else { + forceClose(); + } +} + +void WebSocketClient::forceClose() { + if (m_socket) { + m_socket->close(); + } + m_state = State::Closed; + disconnected.emit(1006, "Connection closed abnormally"); +} + +void WebSocketClient::handleCloseFrame(const WebSocketFrame &frame) { + uint16_t code = 1005; // Default: No status code + std::string reason = "No reason specified"; + + // Extract code and reason if available + if (frame.payload().size() >= 2) { + code = (static_cast(frame.payload()[0]) << 8) | frame.payload()[1]; + if (frame.payload().size() > 2) { + reason = frame.payload().mid(2).toString(); + } + } + + // If we initiated the close, this is the confirmation + if (m_state == State::Closing) { + forceClose(); + } else { + // Server initiated the close, send confirmation and close + m_state = State::Closing; + auto closeFrame = WebSocketFrame::createCloseFrame(code, ""); + sendFrame(closeFrame); + forceClose(); + } + + disconnected.emit(code, reason); +} +``` + +## 5. Integration with Existing Library + +The WebSocketClient implementation fits naturally alongside your existing HttpClient and SseClient implementations: + +1. It leverages the same `Socket`/`TcpSocket`/`SslSocket` infrastructure +2. It uses `HttpClient` for the initial connection setup +3. It follows similar patterns as `SseClient` for event handling + +## 6. Example Usage + +Here's how a user would interact with the WebSocketClient API: + +```cpp +// Create a WebSocket client +auto client = std::make_shared(); + +// Set up event handlers +client->connected.connect([]() { + std::cout << "Connected to WebSocket server" << std::endl; + + // Authenticate after connection + client->sendTextMessage("{\"action\":\"auth\",\"params\":\"API_KEY\"}"); +}); + +client->textMessageReceived.connect([](const std::string &message) { + std::cout << "Received: " << message << std::endl; +}); + +client->disconnected.connect([](uint16_t code, const std::string &reason) { + std::cout << "Disconnected: " << code << " - " << reason << std::endl; +}); + +client->errorOccurred.connect([](const std::string &error) { + std::cout << "Error: " << error << std::endl; +}); + +// Enable auto-reconnect +client->setAutoReconnect(true); +client->setMaxReconnectAttempts(5); +client->setReconnectInterval(std::chrono::seconds(3)); + +// Connect to a WebSocket server +KDUtils::Uri url("wss://socket.polygon.io/stocks"); +client->connectToUrl(url).then([](bool success) { + if (success) { + std::cout << "Connection initiated successfully" << std::endl; + } else { + std::cout << "Failed to initiate connection" << std::endl; + } +}); + +// Send a message +client->sendTextMessage("{\"action\":\"subscribe\",\"params\":\"T.AAPL\"}"); + +// Later, request a graceful disconnection +client->disconnect(1000, "Done with connection"); +``` + +## 7. Implementation Files Structure + +I would suggest organizing the WebSocket implementation with these files: + +1. `websocket_client.h` and `websocket_client.cpp` - Main client API +2. `websocket_frame.h` and `websocket_frame.cpp` - Internal frame handling +3. `websocket_common.h` - Constants and utility functions + +This implementation plan builds on your existing networking stack and follows the same design patterns seen in your other networking classes. Would you like me to elaborate on any specific aspect of this plan? From 13fc32fa08b3aaee9c8ad2b9f2bc2d1a79d0688b Mon Sep 17 00:00:00 2001 From: Sean Harmer Date: Wed, 16 Apr 2025 20:00:27 +0100 Subject: [PATCH 024/110] Rework the websocket connection logic To correctly process any initial websocket frames that may be included in the same TCP packet as the websocket upgrade headers. When the parser pauses for the upgrade, we store the offset in the TCP data and then pass the remaining data to the websocket client. We then use a deferred lambda to emit the connected signal and then process any initial messages in that order. Using the deferred signal emission means we can be sure that the socket's signals have been disconnected from the HttpClient's slots. --- src/KDNetwork/http_client.cpp | 123 +++++++++++++++-------------- src/KDNetwork/http_parser.cpp | 30 ++++++- src/KDNetwork/http_parser.h | 43 ++++++++++ src/KDNetwork/http_response.cpp | 15 ++++ src/KDNetwork/http_response.h | 20 +++++ src/KDNetwork/websocket_client.cpp | 47 +++++++---- src/KDNetwork/websocket_client.h | 6 +- 7 files changed, 205 insertions(+), 79 deletions(-) diff --git a/src/KDNetwork/http_client.cpp b/src/KDNetwork/http_client.cpp index e3884cae..d2bd4041 100644 --- a/src/KDNetwork/http_client.cpp +++ b/src/KDNetwork/http_client.cpp @@ -692,9 +692,26 @@ void HttpClient::onReadyRead(std::shared_ptr state) // Process received data if (state->parser) { - if (!state->parser->parse(data) && !state->websocketUpgrade) { - failRequest(state, "HTTP parsing error");
