Functions ¶

func DetectBackendOnDisk ¶

func DetectBackendOnDisk(root string) string

DetectBackendOnDisk returns the name of the metadata backend being used on disk

func Pathify ¶

func Pathify(id string, depth, width int) string

Pathify segments the beginning of a string into depth segments of width length Pathify("aabbccdd", 3, 1) will return "a/a/b/bccdd"

Types ¶

type Lookup ¶

type Lookup struct {
	Options *options.Options
	// contains filtered or unexported fields
}

Lookup implements transformations from filepath to node and back

func New ¶

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

New returns a new Lookup instance

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!

func (*Lookup) GenerateSpaceID ¶

func (lu *Lookup) GenerateSpaceID(spaceType string, owner *user.User) (string, error)

GenerateSpaceID generates a space id for the given space type and owner

func (*Lookup) InternalPath ¶

func (lu *Lookup) InternalPath(spaceID, nodeID string) string

InternalPath returns the internal path for a given ID

func (*Lookup) InternalRoot ¶

func (lu *Lookup) InternalRoot() string

InternalRoot returns the internal storage root directory

func (*Lookup) MetadataBackend ¶

func (lu *Lookup) MetadataBackend() metadata.Backend

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 ¶

func (lu *Lookup) NodeFromSpaceID(ctx context.Context, spaceID string) (n *node.Node, err error)

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 ¶

func (lu *Lookup) ReadBlobIDAttr(ctx context.Context, path string) (string, error)

ReadBlobIDAttr reads the blobsize from the xattrs

func (*Lookup) ReadBlobSizeAttr ¶

func (lu *Lookup) ReadBlobSizeAttr(ctx context.Context, path string) (int64, error)

ReadBlobSizeAttr reads the blobsize from the xattrs

func (*Lookup) SpacePath ¶

func (lu *Lookup) SpacePath(spaceID string) string

func (*Lookup) TypeFromPath ¶

func (lu *Lookup) TypeFromPath(ctx context.Context, path string) provider.ResourceType

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.
