This is a ruby library for using pid-file based locking of programs/daemons to prevent multiple parallel running tasks.
sys/proctable is required.
require 'sys/proctable' pidlock = Pidlock.new('my.pid') # Instantiates a lock pidlock.lock # tries to create a lock file '/var/run/my.pid'; # raises an error if the file is locked or a program exists that # has the same basename and pid (here: 'my') ... pidlock.unlock # closes and removes the file
- test unlocking in projects.
