Scaffold::Lockmgr - The base class for locking within Scaffold
if ($self->scaffold->lockmgr->try_lock($lock)) { if ($self->scaffold->lockmgr->lock($lock)) { .... $self->scaffold->lockmgr->unlock($lock); } }
This module provides a general purpose locking mechanism to protect shared resources. It is rather interesting to ask a developer how they protect session data and/or global shared data. They usually answer, "I use such-and-such session module, and what do you mean by "global shared data" ?". Well, for those who understand the need for resource locking, this module provides it for Scaffold.
$self->scaffold->lockmgr->allocate($lock);
Reserve a lock by this name. This needs to be done before a lock is used. This name can be used when trying to lock and unlock resources.
$self->scaffold->lockmgr->deallocate($lock);
Removes the reservation for the name. This frees up a lock that can be subseqently reused.
Aquires a lock on a resource, return true if successful.
$self->scaffold->lockmgr->lock($lock);
Releases the lock on a resource.
$self->scaffold->lockmgr->unlock($lock);
Tests to see if the lock on a resource is available, returns true if the lock is available.
$self->scaffold->lockmgr->try_lock($lock);
