Python Process Run Control

Project description

This module provides convenient ways to guarantee a certain script state.


Make sure only one instance of the program is running, this is done by acquiring an fcntl file lock on the current script:

>>> import run.alone


There are a few things to keep in mind:

  1. import run.alone once, it will exit your program if it gets imported twice

  2. symlinked scripts will be resolved to the inode it has been linked to, this is a limitiation of using fcltn file locks


Run until a specified timespec, if the process runs longer, it will be killed:

>>> import run
>>> run.until('23m42s')
>>> ...

You can also choose to limit on the amount of CPU-time being consumed (default is wall clock time):

>>> run.until('42s', 'cpu')
>>> ...


This module is dirived from the Sys::RunAlone and Sys::RunUntil perl modules written by Elizabeth Mattijsen.
