implementing Concurrent TCP Socket Connections in Python 3.9 Using Threading
I'm stuck trying to I'm relatively new to this, so bear with me. I'm having trouble with managing multiple concurrent TCP socket connections in my Python 3.9 application. I am using the `socket` library along with `threading` to handle client connections simultaneously. The question arises when I try to accept multiple connections; sometimes my server behaves as if it's exploring, and I get a `socket.behavior: [Errno 11] Resource temporarily unavailable` when I attempt to read from the sockets. I've implemented the following code snippet to manage connections: ```python import socket import threading def handle_client(client_socket): while True: try: request = client_socket.recv(1024) if not request: break print(f'Received: {request.decode()}') client_socket.send(b'ACK') except Exception as e: print(f'behavior: {e}') break client_socket.close() server = socket.socket(socket.AF_INET, socket.SOCK_STREAM) server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) server.bind(('0.0.0.0', 9999)) server.listen(5) print('Server listening on port 9999') while True: client_socket, addr = server.accept() print(f'Accepted connection from {addr}') client_handler = threading.Thread(target=handle_client, args=(client_socket,)) client_handler.start() ``` I have also set the `SO_REUSEADDR` option to avoid issues with socket binding, and I'm testing it locally with multiple clients. Despite this, under load, it seems like some threads are not processing data as expected, leading to the aforementioned behavior. I’ve tried increasing the `recv` buffer size and added behavior handling in the thread, but the question continues. Is there something I’m missing in terms of thread management or socket configuration that could be causing this scenario? This is part of a larger API I'm building. For context: I'm using Python on Linux. Am I missing something obvious? I'm working in a Ubuntu 22.04 environment. Any ideas how to fix this?
