Functions ¶
func DetectBackendOnDisk ¶ added in v2.13.0
DetectBackendOnDisk returns the name of the metadata backend being used on disk
Types ¶
type Lookup ¶
Lookup implements transformations from filepath to node and back
func (*Lookup) CopyMetadata ¶ added in v2.13.0
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 ¶ added in v2.13.0
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!
func (*Lookup) GenerateSpaceID ¶ added in v2.19.0
GenerateSpaceID generates a new space id and alias
func (*Lookup) InternalPath ¶
InternalPath returns the internal path for a given ID
func (*Lookup) InternalRoot ¶
InternalRoot returns the internal storage root directory
func (*Lookup) MetadataBackend ¶ added in v2.13.0
MetadataBackend returns the metadata backend
func (*Lookup) NodeFromID ¶
func (lu *Lookup) NodeFromID(ctx context.Context, id *provider.ResourceId) (n *node.Node, err error)
NodeFromID returns the internal path for the id
func (*Lookup) NodeFromResource ¶
func (lu *Lookup) NodeFromResource(ctx context.Context, ref *provider.Reference) (*node.Node, error)
NodeFromResource takes in a request path or request id and converts it to a Node
func (*Lookup) NodeFromSpaceID ¶
NodeFromSpaceID converts a resource id into a Node
func (*Lookup) Path ¶
func (lu *Lookup) Path(ctx context.Context, n *node.Node, hasPermission node.PermissionFunc) (p string, err error)
Path returns the path for node
func (*Lookup) ReadBlobIDAttr ¶ added in v2.13.0
ReadBlobIDAttr reads the blobsize from the xattrs
func (*Lookup) ReadBlobSizeAttr ¶ added in v2.13.0
ReadBlobSizeAttr reads the blobsize from the xattrs
func (*Lookup) TypeFromPath ¶ added in v2.13.0
TypeFromPath returns the type of the node at the given path
func (*Lookup) WalkPath ¶
func (lu *Lookup) WalkPath(ctx context.Context, r *node.Node, p string, followReferences bool, f func(ctx context.Context, n *node.Node) error) (*node.Node, error)
WalkPath calls n.Child(segment) on every path segment in p starting at the node r. If a function f is given it will be executed for every segment node, but not the root node r. If followReferences is given the current visited reference node is replaced by the referenced node.
