Just a note to all of those who are interested.
I have yet to get this to work properly for an app which runs indefinitely and
you want to read the output at a specified interval. Right now the only way I
can read is if the _close() method has been called.
Anyway, I wrote a wrapper around it so I could easily change the
implementation if I could ever find a better solution. Here's my code:
===========================
import subprocess
import os
import select
class ProcessMonitor:
def __init__(self):
self.__process = None
self.__stdin = None
self.__stdout = None
def _create(self, process):
self.__process = subprocess.Popen(process, stdin=subprocess.PIPE,
stdout=subprocess.PIPE, close_fds=True)
self.__stdin = self.__process.stdout
self.__stdout = self.__process.stdout
def _close(self):
os.kill(self.__process.pid,9)
def _listen(self):
"""
get from stdout
"""
return "".join(self.__stdout.readlines())
def _listen2(self):
"""
My attempt at trying different things.
"""
inp, out = self.__process.communicate("")
print out
