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.
