How can I reconnect a socket after a broken pipe?

Question

The program connects to a server, and when the connection is closed by the server, if I try to reconnect it says: socket.error: [Errno 9] Bad file descriptor

Answer 1

If the file descriptor is bad then you will need to release that resource and create a new socket. This will get you a new file descriptor.

If the connection terminated abnormally, you will have to wait for the server to close it's end of the connection before you can reconnect. I would just poll it frequently (but not too frequently) to see if you can reestablish a connection with your new socket.

How often do you get the bad pipe error?

Answer 2

Assuming this is a connection oriented socket:

No. You have to close the old one and create a new socket,
