Message86810
the example from
http://docs.python.org/library/multiprocessing.html?highlight=multiprocessing#module-multiprocessing
named "
# Example where a pool of http servers share a single listening socket
#
"
does not work on windows.
Reason:
s = socket.fromfd(fd, family, type_, proto)
in line 156 of reduction.py
fails, because fromfd is not available on windows. Sad thing:
reduction.py was put into processing.py exactly to solve that problem
(i.e. reduction.py is provided as workaround for socket.fromfd not
available on windows, from the documentation:
if sys.platform == 'win32':
import multiprocessing.reduction
# make sockets pickable/inheritable
the solution within processing was:
try:
fromfd = socket.fromfd
except AttributeError:
def fromfd(fd, family, type, proto=0):
s = socket._socket.socket()
_processing.changeFd(s, fd, family, type, proto)
return s
but: _multiprocessing has no longer a method changeFd.
