Name: python-locket
Version: 1.0.0
Release: 1
Summary: File-based locks for Python on Linux and Windows
License: BSD-2-Clause
URL: http://github.com/mwilliamson/locket.py
Source0: https://mirrors.nju.edu.cn/pypi/web/packages/2f/83/97b29fe05cb6ae28d2dbd30b81e2e402a3eed5f460c26e9eaa5895ceacf5/locket-1.0.0.tar.gz
BuildArch: noarch
%description
Locket implements a file-based lock that can be used by multiple processes provided they use the same path.
import locket
# Wait for lock
with locket.lock_file("path/to/lock/file"):
perform_action()
# Raise LockError if lock cannot be acquired immediately
with locket.lock_file("path/to/lock/file", timeout=0):
perform_action()
# Raise LockError 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.
* Calling ``release()`` on an unlocked lock raises ``LockError``.
* Behaviour of locks after ``fork`` is undefined.
