Description: locket.py
=========
Locket implements a lock that can be used by multiple processes provided they use the same path.
.. code-block:: python
import locket
# Wait for lock
with locket.lock_file("path/to/lock/file"):
perform_action()
# Raise error if lock cannot be acquired immediately
with locket.lock_file("path/to/lock/file", timeout=0):
perform_action()
# Raise error if lock cannot be acquired after thirty seconds
with locket.lock_file("path/to/lock/file", timeout=30):
perform_action()
# Without context managers:
lock = locket.lock_file("path/to/lock/file")
try:
lock.acquire()
perform_action()
finally:
lock.release()
Locks largely behave as (non-reentrant) `Lock` instances from the `threading`
module in the standard library. Specifically, their behaviour is:
* Locks are uniquely identified by the file being locked,
both in the same process and across different processes.
* Locks are either in a locked or unlocked state.
* When the lock is unlocked, calling `acquire()` returns immediately and changes
the lock state to locked.
* When the lock is locked, calling `acquire()` will block until the lock state
changes to unlocked, or until the timeout expires.
* If a process holds a lock, any thread in that process can call `release()` to
change the state to unlocked.
* Behaviour of locks after `fork` is undefined.
