KinoSearch::Store::LockFactory - Create Locks.
use Sys::Hostname qw( hostname ); my $hostname = hostname() or die "Can't get unique hostname"; my $folder = KinoSearch::Store::FSFolder->new( path => '/path/to/index', ); my $lock_factory = KinoSearch::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 = KinoSearch::Store::LockFactory->new( folder => $folder, # required host => $hostname, # required );
folder - A KinoSearch::Store::Folder.
host - An identifier which should be unique per-machine.
Return a Lock object, which, once obtain() returns successfully, maintains an exclusive lock on a resource.
name - A file-system-friendly id which identifies the resource to be locked.
timeout - Time in milliseconds to keep retrying before abandoning the attempt to obtain() a lock.
interval - Time in milliseconds between retries.
Return a Lock object for which shared() returns true, and which maintains a non-exclusive lock on a resource once obtain() returns success.
KinoSearch::Store::LockFactory isa KinoSearch::Object::Obj.
