A python package that provides useful locks.
Project description
Overview
A python package that provides useful locks.
It includes the following.
Locking decorator
Helpful locked decorator (that acquires instance objects lock(s) and acquires on method entry and releases on method exit).
Reader-writer locks
Multiple readers (at the same time).
Single writers (blocking any readers).
Helpful read_locked and write_locked decorators.
Inter-process locks
Single writer using file based locking (these automatically release on process exit, even if __release__ or __exit__ is never called).
Helpful interprocess_locked decorator.
Generic helpers
A try_lock helper context manager that will attempt to acquire a given lock and provide back whether the attempt passed or failed (if it passes, then further code in the context manager will be ran with the lock acquired).
