I'm trying to get threading going for the first time in python, and
I'm trying to modify code I found so that I can have the server close
the TCP connections and exit gracefully. Two problems:
1) While the KeyboardInterrupt works, if I make more than 0 curls to
the server and then quit, I can't run it again right away and get
this:
socket.error: [Errno 48] Address already in use
Not all of my connections are closing properly. How do I fix this?
2) curling localhost:8080/quit does show the "Quitting" output that I
expect, but doesn't quit the server until I manually control-c it.
I think that I need *all* threads to close and not just the current
one, so I'm not quite sure how to proceed. Pointers in the right
direction are appreciated. And if there's a "better" way to do this
threading httpd server (subjective, I realize), please let me know!
Thanks.
