- Note: This package is **deprecated**. It is highly preferred that instead of
- using this code base that instead `fasteners`_ or `oslo.concurrency`_ is
- used instead. For any questions or comments or further help needed
- please email `openstack-dev`_ and prefix your email subject
- with ``[oslo][pylockfile]`` (for a faster response).
- The lockfile package exports a LockFile class which provides a simple API for
- locking files. Unlike the Windows msvcrt.locking function, the fcntl.lockf
- and flock functions, and the deprecated posixfile module, the API is
- identical across both Unix (including Linux and Mac) and Windows platforms.
- The lock mechanism relies on the atomic nature of the link (on Unix) and
- mkdir (on Windows) system calls. An implementation based on SQLite is also
- provided, more as a demonstration of the possibilities it provides than as
- production-quality code.
- Note: In version 0.9 the API changed in two significant ways:
- * It changed from a module defining several classes to a package containing
- several modules, each defining a single class.
- * Where classes had been named SomethingFileLock before the last two words
- have been reversed, so that class is now SomethingLockFile.
- The previous module-level definitions of LinkFileLock, MkdirFileLock and
- SQLiteFileLock will be retained until the 1.0 release.
- To install:
- python setup.py install
