Hi, a web server can be incorrectly bound to an already in-use socket when binding a HTTPServer on windows. The issue is discussed here: https://stackoverflow.com/questions/51090637/running-a-python-web-server-twice-on-the-same-port-on-windows-no-port-already
This only happens on Windows. In *nix the socketserver will throw an error, on Windows it will not. However the most recently bound server will not receive the requests.
I suggest the following code (taken from stackoverflow) at the start of the server_bind method:
if hasattr(socket, 'SO_EXCLUSIVEADDRUSE'):
self.socket.setsockopt(socket.SOL_SOCKET, socket.SO_EXCLUSIVEADDRUSE, 1)
# Also need to change the value of allow_reuse_address (defined in http.server.HTTPServer)
HTTPServer.allow_reuse_address = 0
I have tested this and it will throw an error upon reuse in Windows and does not change *nix behavior.
Thanks,
Mike |
