http.server raises exception if scanned with nmap #137710
Description
Bug report
Bug description:
To reproduce, open two terminal instances.
In one terminal instance, type python -m http.server. Output, as expected:
Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) ...
In another terminal instance, type nmap -p 8000 localhost. As expected, it reports (relevant fragment):
PORT STATE SERVICE
8000/tcp open http-alt
In the first terminal instance, the following exception occurs:
Exception occurred during processing of request from ('127.0.0.1', 47284)
