I have a small development WSGI-server using PythonPaste and when shutting it down I somtimes get the following error on one or two threads:


-----------------------8<-----------------------------------

So I recon its a bug...

Sorry forgot to tell in what versions..


Its in Ubuntu 12.04-1 Python version 2.7.3

Ubuntu package version: 2.7.3-0ubuntu3.1

request should be socket.socket instance which definitely has shutdown method accepting socket.SHUT_WR.
I guest the problem not in stdlib but in your code or maybe in the Paste (I'm not familiar with it, sorry).

Move to pending until additional info will be provided.
Required short test to reproduce the problem.

Looks an invalid bug to me as well. request is a socket.socket object and has shutdown method taking a single argument. 
The error pasted in the report leads me to believe if the shutdown_request call is not thread-safe and it is ending up called shutdown method in the module instead of the proper shutdown method of the request object.

Given the lack of additional info from the OP, I'm closing this.
