I've got a case where I need to tweak the implementation of a default python library due to what I consider to be an issue in the library.
What is the best way to do this and make an attempt to remain compatible with future releases? My specific problem is with the clock used in the threading.Event and threading.Timer. It currently uses time.time, which is affected by changes in system time. eg: if you change the system clock somehow at some time (say, with an NTP broadcast) you may get a surprise in the timing of your code execution. What I do right now is basically this: import sys import time import threading if sys.platform == 'win32': threading._time = time.clock in which case I'm simply forcing the internal clock used in the Event/Timer code to use a time-independent performance timer rather than the system time. I figured this is a much better way to do it than snagging a private copy of threading.py and making a direct change to it, but am curious if anyone has a better way of doing this type of thing? For example, I have no way of guaranteeing that this hack will work come a change to 2.5 or later. Thanks, Russ -- http://mail.python.org/mailman/listinfo/python-list
