I have a socket that I want to timeout when connecting so that I can cancel the whole operation if it can't connect yet it also want to use the makefile for the socket which requires no timeout.
Is there an easy way to do this or is this going to be a difficult thing to do?
Does python allow a reset of the timeout after connected so that I can use makefile and still have a timeout for the socket connection

Socket connection timeout High A new Python socket by default doesn't have a timeout. Its timeout defaults to None. Not setting the connection timeout parameter can result in blocking socket mode. In blocking mode, operations block until complete or the system returns an error.
The typical approach is to use select() to wait until data is available or until the timeout occurs. Only call recv() when data is actually available. To be safe, we also set the socket to non-blocking mode to guarantee that recv() will never block indefinitely.
Answer: Just set the SO_TIMEOUT on your Java Socket, as shown in the following sample code: String serverName = "localhost"; int port = 8080; // set the socket SO timeout to 10 seconds Socket socket = openSocket(serverName, port); socket. setSoTimeout(10*1000);
In Python, use the stdin. readline() and stdout. write() instead of input and print. Ensure that the input value to test cases is passed in the expected format.
You just need to use the socket settimeout() method before attempting the connect(), please note that after connecting you must settimeout(None) to set the socket into blocking mode, such is required for the makefile . Here is the code I am using:
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.settimeout(10) sock.connect(address) sock.settimeout(None) fileobj = sock.makefile('rb', 0) If you are using Python2.6 or newer, it's convenient to use socket.create_connection
sock = socket.create_connection(address, timeout=10) sock.settimeout(None) fileobj = sock.makefile('rb', 0) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
