Summary: logging.handlers.SocketHandler.makeSocket() blocks app
Initial Comment:
Python Version:
===============
Any Python Version
OS Platform:
============
Debian Linux 2.6.8-2-386 #1 Tue Aug 16 12:46:35 UTC 2005 i686 GNU/Linux
Windows XP SP2
Problem:
========
Member function makeSocket() of logging.handlers.SocketHandler creates a socket
with no default timeout, and this may block the app on Linux.
def makeSocket(self):
"""
A factory method which allows subclasses to define the precise
type of socket they want.
"""
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((self.host, self.port))
return s
if the log receiver on the destination host is not running, the log sender will
block the app on socket.connect(), but on windows, socket.connect() will return
immediately. So I propose to provide a default timeout value for makeSocket()
like below:
def makeSocket(self, timeout=1):
"""
A factory method which allows subclasses to define the precise
type of socket they want.
"""
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.settimeout(timeout)
s.connect((self.host, self.port))
return s
