Python Process Run Control
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:
- import run.alone once, it will exit your program if it gets imported twice
- 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') >>> ...
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
