Node.js http IncomingMessage setTimeout callback socket timeout listener removal keep-alive official documentation

💡 Result:

In Node.js, the behavior of message.setTimeout(msecs, callback) on an http.IncomingMessage instance has historically been a subject of community confusion regarding callback execution [1][2]. According to official documentation and technical context, when you call message.setTimeout(msecs, callback), the callback is intended to be invoked when a 'timeout' event occurs [3][4]. However, historically, developers have reported that the callback provided to message.setTimeout might not be triggered as expected because the IncomingMessage object itself did not reliably emit the 'timeout' event in certain versions [2]. The setTimeout method on an IncomingMessage typically delegates to the underlying socket's setTimeout method [3]. To ensure a timeout listener is handled correctly, it is standard practice to bind directly to the socket or monitor the 'timeout' event on the request/response object explicitly, while keeping in mind that setTimeout only notifies that the socket has been idle and does not automatically abort the request [5][6]. Regarding listener removal and keep-alive: 1. Listener Removal: Node.js does not automatically remove timeout listeners attached via message.setTimeout when a socket is reused for keep-alive connections. If you attach listeners manually, you must manage their lifecycle (e.g., using removeListener or once) to prevent memory leaks or unexpected behavior during socket reuse. 2. Keep-Alive Interaction: Socket timeouts are heavily influenced by the server's keepAliveTimeout configuration [7][8]. When using keep-alive, Node.js manages idle sockets to allow for reuse. If a socket is idle and exceeds the keepAliveTimeout, the server will close it [7]. Developers should prefer using server.keepAliveTimeout to control idle connection duration rather than relying on manual socket timeouts, as the latter can be preempted or overridden by internal server logic during the keep-alive lifecycle [7][8]. For robust timeout management, rely on the server-level configuration options such as headersTimeout, requestTimeout, and keepAliveTimeout provided in the http.createServer() or http.request() options [9][8].

site:nodejs.org/api/http.html IncomingMessage setTimeout socket timeout callback

💡 Result:

In Node.js, the http.IncomingMessage class does not possess a setTimeout method [1]. The setTimeout method is a feature of http.ClientRequest (for outgoing requests) or part of the underlying socket handling for server-side connections [1]. When you are working with an http.IncomingMessage object (which represents the response in a client request or the request in a server listener), you can monitor inactivity by accessing the underlying socket directly [1]. Key points regarding timeout handling: 1. Timeout Event: The http.IncomingMessage object inherits from stream.Readable and emits a 'timeout' event when the underlying socket times out due to inactivity [1]. 2. Manual Destruction: Receiving the 'timeout' event only signals that the socket has been idle; it does not automatically close or destroy the stream. You must manually call request.destroy or response.destroy to terminate the connection [1]. 3. Socket Access: If you need to set a timeout on the underlying socket for an incoming message, you can generally access the socket via the message.socket property (e.g., message.socket.setTimeout(msecs, callback)) [1]. If you are dealing with a client-side request, use request.setTimeout(timeout, callback) on the http.ClientRequest object before the request is sent to manage timeouts effectively [1].

site:nodejs.org/api/http.html "message.setTimeout(msecs" "IncomingMessage"

💡 Result:

In Node.js, there is no direct method named message.setTimeout(msecs) for the http.IncomingMessage class [1]. The http.IncomingMessage object, which represents the incoming message in an HTTP server or the response in an HTTP client request, does not provide a built-in timeout method [1]. If you are looking to manage timeouts for HTTP connections in Node.js, consider these alternatives: 1. Server-level Timeouts: For an HTTP server, you can set a timeout using server.setTimeout([msecs][, callback]), which applies to all sockets connected to that server [1]. 2. Request-level Timeouts: For client-side requests, you use request.setTimeout(timeout[, callback]) on the http.ClientRequest object [1]. 3. Socket-level Timeouts: Since http.IncomingMessage is associated with an underlying socket, you can access that socket via message.socket and call socket.setTimeout(msecs) to manage inactivity timeouts directly on the connection [1]. Note that when a socket times out, the 'timeout' event is emitted, but the connection is not automatically destroyed; you must manually call request.destroy or socket.destroy to terminate the connection [1].

Bun node:http IncomingMessage setTimeout socket timeout compatibility documentation

💡 Result:

In Bun, the node:http IncomingMessage.setTimeout method is implemented to provide compatibility with Node.js [1][2]. This method delegates the timeout logic to the underlying socket (or the request's native handle), maintaining behavioral parity with Node.js by invoking the socket's timeout mechanism [1][3]. Key details regarding Bun's implementation include: Mechanism: Calling message.setTimeout(msecs, callback) essentially maps to the underlying socket's timeout functionality [1][3]. In Bun's node:http module, this is wired to native per-connection inactivity timers [3][4]. When the specified duration (msecs) passes without activity, a timeout event is emitted [3][4]. Compatibility Progress: - Bun has actively iterated to ensure these methods behave like Node.js, including fixes to properly unref timers so they do not unnecessarily keep the event loop alive [5][4]. - Recent updates have ensured that server-side timeout listeners (on the server, request, or response) can correctly veto the default socket destruction behavior, matching the established Node.js contract [4]. - Improvements have also been made to ensure timeouts correctly fire during the connection phase (e.g., against dead or firewalled hosts), addressing past gaps in timeout event emission [6]. While Bun aims for high compatibility, users should be aware that implementation details for networking primitives are subject to ongoing refinement as part of the broader effort to support the full Node.js API surface [7][8]. If you encounter specific issues with socket timeout behavior, ensure your Bun version is up to date, as many historical limitations related to socket.setTimeout stubs or silent failures have been resolved in recent releases [3][9][10].

Reset the socket timeout when the response stream terminates.

response.setTimeout() at src/lib/pinned-http.ts:152 attaches its callback to IncomingMessage, not to response.socket. Remove the proposed socket.off() cleanup. Capture the socket before the "end" handler runs, then call socket.setTimeout(0) on "end", "error", output-limit failure, and cancellation. The current code leaves a one-shot timeout armed on pooled keep-alive sockets.
