New submission from Terry J. Reedy:
https://docs.python.org/2/library/multiprocessing.html#examples
contains several examples in Python2 code that need to be updated for Python 3.
Richard, if you have them in .py files, perhaps you could run them through 2to3
and then test.
# Example where a pool of http servers share a single listening socket
from BaseHTTPServer import HTTPServer
from SimpleHTTPServer import SimpleHTTPRequestHandler
...
print 'Serving at http://%s:%d using %d worker processes' % \
(ADDRESS[0], ADDRESS[1], NUMBER_OF_PROCESSES)
print 'To exit press Ctrl-' + ['C', 'Break'][sys.platform=='win32']
#update
from http.server import HTTPServer, SimpleHTTPRequestHandler
...
print('Serving at http://%s:%d using %d worker processes' % \
(ADDRESS[0], ADDRESS[1], NUMBER_OF_PROCESSES))
print('To exit press Ctrl-' + ['C', 'Break'][sys.platform=='win32'])
This still does not run on Windows
_pickle.PicklingError: Can't pickle <class '_thread.lock'>: attribute lookup
lock on _thread failed
but that was true in 2.7 also (#21204).
