ForkMe

======

Fork your proccess like a boss

.. code-block:: python

    import forkme

    import logging

    import os

    from time import sleep

    logging.basicConfig(level=logging.DEBUG)

    def main():

        print("Master proccess has PID: {0}".format(os.getpid()))

        forkme.fork(4)

        print(

            "Proceess #{id} has PID: {pid}".format(

                id=forkme.get_id(),

                pid=os.getpid()

            )

        )

        sleep(1)

    if __name__ == '__main__':

        main()

This code makes 4 forks. When you try to run it you will see something like this ::

    Master proccess has PID: 7437

    INFO:forkme:Starting 4 processes

    Proceess #2 has PID: 7440

    Proceess #1 has PID: 7439

    Proceess #3 has PID: 7441

    Proceess #0 has PID: 7438

    INFO:forkme:Child with PID: 7439 Number: 1 exited normally

    INFO:forkme:Child with PID: 7441 Number: 3 exited normally

    INFO:forkme:Child with PID: 7440 Number: 2 exited normally

    INFO:forkme:Child with PID: 7438 Number: 0 exited normally

Forkme will be control forks. When subprocess will be killed or will exit with 

non-zero code it will be restarted immediately. e.g.::

    Master proccess has PID: 7579

    INFO:forkme:Starting 4 processes

    Proceess #0 has PID: 7580

    Proceess #1 has PID: 7581

    Proceess #2 has PID: 7582

    Proceess #3 has PID: 7583

    WARNING:forkme:Child with PID: 7580 Number: 0 killed by signal 9, restarting

    Proceess #0 has PID: 7584

    INFO:forkme:Child with PID: 7581 Number: 1 exited normally

    INFO:forkme:Child with PID: 7582 Number: 2 exited normally

    INFO:forkme:Child with PID: 7583 Number: 3 exited normally

    INFO:forkme:Child with PID: 7584 Number: 0 exited normally
