Lucy::Store::LockFactory - Create Locks.
use Sys::Hostname qw( hostname ); my $hostname = hostname() or die "Can't get unique hostname"; my $folder = Lucy::Store::FSFolder->new( path => '/path/to/index', ); my $lock_factory = Lucy::Store::LockFactory->new( folder => $folder, host => $hostname, ); my $write_lock = $lock_factory->make_lock( name => 'write', timeout => 5000, interval => 100, );
LockFactory is used to spin off interprocess mutex locks used by various index reading and writing components. The default implementation uses lockfiles, but LockFactory subclasses which are implemented using alternatives such as flock() are possible.
my $lock_factory = Lucy::Store::LockFactory->new( folder => $folder, # required host => $hostname, # required );
Create a new LockFactory.
my $lock = $lock_factory->make_lock( name => $name # required timeout => $timeout # default: 0 interval => $interval # default: 100 );
Return a Lock object, which, once obtain() returns successfully, maintains an exclusive lock on a resource.
my $lock = $lock_factory->make_shared_lock( name => $name # required timeout => $timeout # default: 0 interval => $interval # default: 100 );
Lucy::Store::LockFactory isa Clownfish::Obj.
