Description (last modified by greiner)


Ubuntu 14.04

How to reproduce

  1. Start test server with ./
  2. Open http://localhost:5000/options.html
  3. Kill process using CTRL+C

Observed behavior

Console shows the following error message:

socket.error: [Errno 98] Address already in use

Expected behavior

Server should start up normally without any error messages being shown.


Python keeps ports open in case any extra packets show up so telling it to reuse those should be sufficient. However, that requires us to manually bind to the port.

What to change

  • Set the third argument in the server constructor to False to indicate that we want to bind to the port manually.
  • Set the server's allow_reuse_address property to True.
  • Call server_bind() and server_activate() before starting the server.
