This allows modules to be cleaned up in the reverse order from which they are imported (and therefore register their atexit functions), which should reduce dependency conflicts. $ python atexit_multiple.py my_cleanup(third) import atexit import os def not_called(): print 'This should not be called' print 'Registering' atexit.register(not_called) print 'Registered' print 'Exiting...' os._exit(0) Since we call os._exit() instead of exiting normally, the callback is to the beginning of a comment is redundant because by being a comment it is already implicit that it should be noted. import atexit def my_cleanup(name): print 'my_cleanup(%s)' % name atexit.register(my_cleanup, 'first') atexit.register(my_cleanup, 'second') atexit.register(my_cleanup, 'third') Notice that order in which the exit functions are called is the reverse of the order they

A simple work-around (which does not require people to upgrade to a bugfixed version of Python) is to put try: import multiprocessing except ImportError: pass near the beginning of setup.py.

If you are looking for examples that work under Python 3, please refer to the PyMOTW-3 section of the site. Examples¶ A simple example of registering a function via atexit.register() looks like: import atexit def all_done(): print 'all_done()' print 'Registering' atexit.register(all_done) print 'Registered' Since the program doesn't do anything else, all_done()

The main thread spawns 1 to N processes and waits until they all done processing. Reload to refresh your session. This allows modules to be cleaned up in the reverse order from which they are imported (and therefore register their atexit functions), which should reduce dependency conflicts. $ python atexit_multiple.py my_cleanup(third) That all being said, I have never seriously used the multiprocessing package before and have never peeked into travis-ci's source so I'm not sure what is going wrong where.
From a cursory glance at the error message, and multiprocessing/util.py, I'm fairly certain _logger for some reason or another is NoneType (possibly get_logger() was never called?) and thus the info('process shutting After this change I don't get the error when running "python setup.py test". Travis CI member roidrage commented Dec 28, 2013 When in doubt, we could build our own packages, though I'm fairly sure someone should have 2.7.5 or 2.7.4 packages available somewhere. I'll take another look over the weekend, but it seems to be ready to be applied.
