The arguments that are most commonly needed are: args is required for all calls and should be a string, or a sequence of program arguments. David says: November 6, 2013 at 10:53 am Hi Fandi, Can you post you cacti configuration and server spesification ? If passing a single string, either shell must be True (see below) or else the string must simply name the program to be executed without specifying any arguments. def kill_proc_tree(pid, including_parent=True): parent = psutil.Process(pid) children = parent.children(recursive=True) for child in children: child.kill() psutil.wait_procs(children, timeout=5) if including_parent: parent.kill() parent.wait(5) def run_with_timeout(cmd, current_dir, cmd_parms, timeout): def target(): process = subprocess.Popen(cmd, cwd=current_dir, have a peek at this web-site
For more information see the documentation of the io.TextIOWrapper class when the newline argument to its constructor is None. output¶ Output of the child process if it was captured by run() or check_output(). As a result we are closing it. self.stdin.flush() if not input: self.stdin.close() read_set, write_set = ,  stdout = stderr = None if self.stdin and input: write_set.append(self.stdin) if self.stdout: read_set.append(self.stdout) stdout =  if self.stderr: read_set.append(self.stderr) stderr =
New in version 3.6: Added encoding and errors parameters. Security Considerations¶ Unlike some other popen functions, this implementation will never implicitly call a system shell. When shell=False, executable replaces the program to execute specified by args.

- You don't need lambda: t = Timer(timeout, proc.kill) –J.F.
- On Windows kill() is an alias for terminate().
- If the encoding or errors arguments were specified or the universal_newlines argument was True, the stream is a text stream, otherwise it is a byte stream.
- which will be "SUBPROCESS2_PROCESS_COMPLETED" if the process completed normally, or a mask of "SUBPROCESS2_PROCESS_TERMINATED" and SUBPROCESS2_PROCESS_KILLED depending on action taken (see documentation for full details) share|improve this answer edited Sep 25
- process.stdin.close() if process.wait() != 0: print("There were some errors") 22.214.171.124.
- Otherwise, file objects are opened in binary mode.
If you must use it, keep it trivial! from logging import error from subprocess import Popen from threading import Event from threading import Thread class ExpirablePopen(Popen): def __init__(self, *args, **kwargs): self.timeout = kwargs.pop('timeout', 0) self.timer = None self.done = The full function signature is largely the same as that of run() - most arguments are passed directly through to that interface. Python Timeout Function class Alarm(Exception): pass def alarm_handler(signum, frame): raise Alarm signal.signal(signal.SIGALRM, alarm_handler) signal.alarm(5*60) # 5 minutes try: stdoutdata, stderrdata = proc.communicate() signal.alarm(0) # reset the alarm except Alarm: print "Oops, taking too long!"

Moderators: Moderators, Developers 3776 23096 Sat Jan 07, 2017 11:24 pm jackdanpr Help: Unstable Development Versions If you happen to be using a SVN or pre-release version of Cacti and have Note Do not use stdout=PIPE or stderr=PIPE with this function. Example: >>> subprocess.getoutput('ls /bin/ls') '/bin/ls' Availability: POSIX & Windows Changed in version 3.3.4: Windows support added 17.5.8.
But you can call communicate() several times with smaller timeouts. Python Thread Timeout However, this can only be done if not passing arguments to the program. CACTID: Host ERROR: The POPEN timed out CACTID: Host DS WARNING: Result from SCRIPT not valid. I would like to see your feedback as I am considering this version just about ready to go.

The child process could deadlock before exec is called. Source So, to wait up to 10 seconds for the process to terminate, otherwise kill: pipe = subprocess.Popen('...') timeout = 10 results = pipe.waitOrTerminate(timeout) This is compatible with both windows and unix.
Older high-level API¶ Prior to Python 3.5, these three functions comprised the high level API to subprocess.

The terminate() function marks a thread as terminated, but does not actually terminate the thread!
