Pidfile featuring stale detection and file-locking, can also be used as context-manager or decorator

Project description

https://travis-ci.org/trbs/pid.svg?branch=master https://coveralls.io/repos/trbs/pid/badge.png

PidFile class featuring:

  • stale detection

  • pidfile locking (fcntl)

  • chmod (default is 0o644)

  • chown

  • custom exceptions

Context Manager

PidFile can be used as a context manager:

from pid import PidFile

with PidFile():
  do_something()

Decorator

PidFile can also be used a a decorator:

from pid.decorator import pidfile

@pidfile
def main():
  pass

if __name__ == "__main__":
  main()

Exception Order

In default mode PidFile will try to acquire a file lock before anything else. This means that normally you get a PidFileAlreadyLockedError instead of the PidFileAlreadyRunningError when running a program twice.

If you just want to know if a program is already running its easiest to use just PidFileError since it will capture all possible PidFile exceptions.
