Here is another data point. I added some print calls to the subprocess
module and ran the key call from the interpreter:
% ./python.exe
Python 3.1a0 (py3k:68218, Jan 3 2009, 15:06:30)
[GCC 4.0.1 (Apple Inc. build 5490)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import subprocess
>>> import sys
>>> cmd_line = [sys.executable, '-E']>>> cmd_line.extend(['-c',
"assert(ord('\xe9') == 0xe9)"])
>>> subprocess.call(cmd_line, stdout=subprocess.PIPE,
stderr=subprocess.PIPE)
1 wait, returncode= None
2 wait, pid= 4029 sts= 256
5 _handle_exitstatus WIFEXITED
3 wait, returncode= 1
1
>>> os.WIFEXITED(256)
True
>>> os.WEXITSTATUS(256)
1
>>> 256 & 255
0
A return code of 256 seems to me like the exit code should be 0. From my
Mac's wait(2) man page:
WEXITSTATUS(status)
If WIFEXITED(status) is true, evaluates to the low-order 8 bits
of the argument passed to _exit(2) or exit(3) by the child.
What's with the WEXITSTATUS return value of 1?
