New submission from Benjamin VENELLE <[email protected]>:
Hi,
The following code results in an infinite loop -->
# ----
import multiprocessing
def f(m):
print(m)
p = multiprocessing.Process(target=f, args=('pouet',))
p.start()
# ----
I've firstly think about an issue in my code when Python loads this module so
I've added a "if __name__ == '__main__':" and it works well. But, with the
following code Python enters in the same infinite loop -->
proc.py:
# ----
import multiprocessing
def f(m):
print(m)
class P:
def __init__(self, msg):
self.msg = msg
def start(self):
p = multiprocessing.Process(target=f, args=(self.msg,))
p.start()
# ----
my_script.py:
# ----
from proc import P
p = P("pouet")
p.start()
# ----
It's like Python loads all parent's process memory space before starting
process which issues in an infinite call to Process.start() ...
