[issue12098] Child process running as debug

2011-05-17 Thread Sergey Mezentsev 

New submission from Sergey Mezentsev :

I run this code:
"""
from multiprocessing import Pool

def myfunc(x):
assert False
#if __debug__: print 'debug'
return x - 1

if __name__ == '__main__':
pool = Pool(processes=1)
it = pool.imap(myfunc, xrange(5)) # or imap_unordered, map
print it.next()

python -O myscript.py
"""

The myfunc() always raise AssertionError. But I run script with "-O" 
(optimization) command.

Interpreter is:
"""
Python 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 bit (Intel)] on 
win32
"""

Thanks!

In my system (Windows 7 (64) SP1, Python 2.6.6 32-bit) I have:

[issue12098] Child process running as debug on Windows

2011-05-18 Thread Sergey Mezentsev 

Sergey Mezentsev  added the comment:

I create patch for Popen.get_command_line() ('2.6' and 'default' branches).

I don't know how to write the test. The sys.flags structure are read only.
