NAME

       Pinto::Locker - Manage locks to synchronize concurrent operations

VERSION

       version 0.097

DESCRIPTION

METHODS

   lock
       Attempts to get a lock on a Pinto repository.  If the repository is already locked, we
       will attempt to contact the current lock holder and make sure they are really alive.  If
       not, then we will steal the lock.  If they are, then we patiently wait until we timeout,
       which is about 60 seconds.

   unlock
       Releases the lock on the Pinto repository so that other processes can get to work.

       In many situations, a Pinto repository is a shared resource.  At any given moment,
       multiple processes may be trying to add distributions, remove packages, or pull files from
       a mirror.  To keep things working properly, we can only let one process fiddle with the
       repository at a time.  This module manages a lock file for that purpose.

       Supposedly, this does work on NFS.  But it cannot steal the lock from a dead process if
       that process was not running on the same host.
