#19547 — Questions regarding the daemon module.

I was looking for a simple way to daemonize a Python process, and found:

http://www.python.org/dev/peps/pep-3143/

I used easy_install to add this package (I thought), but when I 
attempted to use the example in the above link, I got the error:


AttributeError: 'module' object has no attribute 'DaemonContext'

To my surprise when looking at the module that was installed, I found 
something completely different to what was in the documentation:

 >>> dir(daemon)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', 
'basic_daemonize', 'checkPID', 'daemonize', 'errno', 'os', 'sys', 
'writePID']
 >>>
 >>> print daemon.__doc__
None
 >>>
 >>> print daemon.daemonize.__doc__
None
 >>>


Further experimentation with this module yielded a working daemon, but I 
am concerned regarding its parentage and lack of documentation. Could 
someone explain these discrepancies?


Best regards,

Dave.

What command did you use to install ‘python-daemon’?
