[issue15756] subprocess.poll() does not handle errno.ECHILD No child processes

2012-08-21 Thread Todd Whiteman 

New submission from Todd Whiteman:

In the case of a errno.ECHILD exception - Python's subprocess module misses 
the fact that the process has already ended.

The following code will wait indefinitely, even though the launched process is 
quickly ended:

import subprocess, signal
signal.signal(signal.SIGCLD, signal.SIG_IGN)
p = subprocess.Popen(['echo','foo'])
while p.poll() is None:
   pass # wait for the process to exit

Note: This is the exact same issue as issue1731717, but applying to the 
subprocess.poll() method instead of the subprocess.wait() method.

[issue15756] subprocess.poll() does not handle errno.ECHILD No child processes

2012-08-21 Thread Todd Whiteman 

Todd Whiteman added the comment:

The attached patch handles errno.ECHILD in the _internal_poll() method and I've 
updated the existing sigchild_ignore.py test file to perform polling as well.

An unpatched version of Pyhton would normally hang on this particular test, 
whilst the patched version will run successfully.

[issue3905] subprocess failing in GUI applications on Windows

2011-04-05 Thread Todd Whiteman 

Todd Whiteman twhit...@yahoo.com.au added the comment:

I still see this problem (in Python 2.7.1 and Python 3.1.2).

When testing using idle, you'll need to launch using pythonw.exe, i.e.:

pythonw.exe lib\idlelib\idle.py

[issue8350] os.mkdir doc comment is incorrect

2010-04-08 Thread Todd Whiteman 

New submission from Todd Whiteman twhit...@yahoo.com.au:

The doc command for os.mkdir is incorrect (at least for posix). It specifies 
that there is an optional mode keyword, but it's not a keyword argument, see 
below:

 import os
 help(os.mkdir)
mkdir(...)
mkdir(path [, mode=0777])

Create a directory.

 os.mkdir(/tmp/1, mode=777) 
Traceback (most recent call last):
  File stdin, line 1, in module
TypeError: mkdir() takes no keyword arguments


Suggest the following doc comment change:

mkdir(...)
mkdir(path [, mode])

Create a directory. Mode defaults to 0777 if not specified.

[issue3905] subprocess failing in GUI applications on Windows

2008-09-21 Thread Todd Whiteman 

Todd Whiteman [EMAIL PROTECTED] added the comment:

Uh, the Idle bug reported by Jean-Michel is a completely different bug
(please see the first three messages of this report).

Please re-open this bug, as the subprocess issue I have reported is
still outstanding.
