New submission from Ross Lagerwall <rosslagerw...@gmail.com>:
Running subprocess as a module invokes some demo functions.
On posix, one of these doesn't work:
$ ./python -m subprocess
Process list:
b' PID TTY TIME CMD\n 9003 pts/6 00:00:00 python\n 9004 pts/6
00:00:00 ps\n23760 pts/6 00:00:00 bash\n'
Looking for 'hda'...
b''
Trying a weird file...
The file didn't exist. I thought so...
Child traceback:
Traceback (most recent call last):
File "/home/ross/code/py3kdev/silly/Lib/subprocess.py", line 1757, in
_demo_posix
print(Popen(["/this/path/does/not/exist"]).communicate())

raise child_exception_type(errno_num, err_msg)
OSError: [Errno 2] No such file or directory: '/this/path/does/not/exist'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/home/ross/code/py3kdev/silly/Lib/runpy.py", line 160, in

print(e.child_traceback)
AttributeError: 'OSError' object has no attribute 'child_traceback'
I think these demo functions should be either be removed or incorporated into
the docs.
