python3-locket Subpackage of python-locket

Locket implements a lock that can be used by multiple processes provided they use the same path. 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.
