Types

type DB

type DB struct {
	// contains filtered or unexported fields
}

DB stores metadata about the state of the directory and any data that has been imported from it.

func NewDB

func NewDB(conn *sqlutil.Conn, paramHash [32]byte) *DB

func (*DB) Delete

func (db *DB) Delete(ctx context.Context, p string) error

Delete removes all information associated with a path.

func (*DB) GetFSRoot

func (db *DB) GetFSRoot(ctx context.Context, p string, dst *gotfs.Root) (bool, error)

func (*DB) GetInfo

func (db *DB) GetInfo(ctx context.Context, p string, dst *FileInfo) (bool, error)

func (*DB) PutFSRoot

func (db *DB) PutFSRoot(ctx context.Context, p string, modt tai64.TAI64N, fsroot gotfs.Root) error

func (*DB) PutInfo

func (db *DB) PutInfo(ctx context.Context, ent FileInfo) error

type ErrWouldClobber

type ErrWouldClobber struct {
	Op   string
	Path string
}

func (ErrWouldClobber) Error

func (e ErrWouldClobber) Error() string

type Exporter

type Exporter struct {
	// contains filtered or unexported fields
}

func NewExporter

func NewExporter(gotfs *gotfs.Machine, db *DB, fsx posixfs.FS, filter func(p string) bool) *Exporter

func (*Exporter) Clobber

func (pr *Exporter) Clobber(ctx context.Context, ms, ds stores.Reading, root gotfs.Root, p string) error

func (*Exporter) ExportFile

func (pr *Exporter) ExportFile(ctx context.Context, ms, ds stores.Reading, root gotfs.Root, p string) error

func (*Exporter) ExportPath

func (pr *Exporter) ExportPath(ctx context.Context, ms, ds stores.Reading, root gotfs.Root, p string) error

ExportPaths checks what is at p in root, and then exports the directory or file to the filesystem.

type FileInfo

type FileInfo struct {
	Path       string
	ModifiedAt tai64.TAI64N
	Mode       fs.FileMode
	Size       int64
}

type Importer

type Importer struct {
	// contains filtered or unexported fields
}

func NewImporter

func NewImporter(fsmach *gotfs.Machine, db *DB, ss [2]stores.RW) *Importer

func (*Importer) ImportFile

func (pr *Importer) ImportFile(ctx context.Context, fsx posixfs.FS, p string) (*gotfs.Root, error)

func (*Importer) ImportPath

func (pr *Importer) ImportPath(ctx context.Context, fsx posixfs.FS, p string) (*gotfs.Root, error)

ImportPath returns gotfs instance containing the content in fsx at p. The content will be at the root of the filesystem.

type Span

type Span struct {
	Begin string
	End   string
}

Span is a span of paths

func (Span) Contains

func (s Span) Contains(x string) bool

func (Span) IsPrefix

func (s Span) IsPrefix() bool

func (Span) String

func (s Span) String() string
