IDCache is a cache for node ids

type Lookup 

type Lookup struct {
	Options *options.Options

	IDCache IDCache
	// contains filtered or unexported fields
}

Lookup implements transformations from filepath to node and back

func New 

func New(b metadata.Backend, um usermapper.Mapper, o *options.Options) *Lookup

New returns a new Lookup instance

func (lu *Lookup) CacheID(ctx context.Context, spaceID, nodeID, val string) error

CacheID caches the path for the given space and node id

func (*Lookup) CopyMetadata 

func (lu *Lookup) CopyMetadata(ctx context.Context, src, target string, filter func(attributeName string, value []byte) (newValue []byte, copy bool), acquireTargetLock bool) (err error)

CopyMetadata copies all extended attributes from source to target. The optional filter function can be used to filter by attribute name, e.g. by checking a prefix For the source file, a shared lock is acquired. NOTE: target resource will be write locked!

func (*Lookup) CopyMetadataWithSourceLock 

func (lu *Lookup) CopyMetadataWithSourceLock(ctx context.Context, sourcePath, targetPath string, filter func(attributeName string, value []byte) (newValue []byte, copy bool), lockedSource *lockedfile.File, acquireTargetLock bool) (err error)

CopyMetadataWithSourceLock copies all extended attributes from source to target. The optional filter function can be used to filter by attribute name, e.g. by checking a prefix For the source file, a matching lockedfile is required. NOTE: target resource will be write locked!
