flockfile
Just a simple python lock file class using file locks.
Installation
pip install flockfile
Usage
from flockfile import FlockFile, FileNotLocked
# init the class using a file name
# optionally, the directory can be set to something other than /tmp
lock = FlockFile("myscriptname", lock_dir="/tmp")
# lock the file
lock.lock()
# if this is unsuccessful, exception FileNotLocked will be raised.
# the following class method can be used to check lock status
assert lock.check_lock()
# unlock and delete file
lock.unlock()
FlockFile can also be used as a context manager. The lock is acquired on entry
(raising FileNotLocked if it cannot be obtained) and released on exit:
from flockfile import FlockFile
with FlockFile("myscriptname", lock_dir="/tmp"):
# the lock is held here
...
# the lock is released and the file deleted here
