Functions

func NewFs

func NewFs(ctx context.Context, name, root string, m configmap.Mapper) (ff fs.Fs, err error)

NewFs constructs an Fs from the path, container:path

Types

type FileInfo

type FileInfo struct {
	Name    string
	Size    uint64
	ModTime time.Time

	IsDir bool
	// contains filtered or unexported fields
}

FileInfo is the metadata known about an FTP file

type Fs

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

Fs represents a remote FTP server

func (*Fs) DirMove

func (f *Fs) DirMove(ctx context.Context, src fs.Fs, srcRemote, dstRemote string) error

DirMove moves src, srcRemote to this remote at dstRemote using server-side move operations.

Will only be called if src.Fs().Name() == f.Name()

If it isn't possible then return fs.ErrorCantDirMove

If destination exists then return fs.ErrorDirExists

func (*Fs) Features

func (f *Fs) Features() *fs.Features

Features returns the optional features of this Fs

func (*Fs) Hashes

func (f *Fs) Hashes() hash.Set

Hashes are not supported

func (*Fs) List

func (f *Fs) List(ctx context.Context, dir string) (entries fs.DirEntries, err error)

List the objects and directories in dir into entries. The entries can be returned in any order but should be for a complete directory.

dir should be "" to list the root, and should not have trailing slashes.

This should return ErrDirNotFound if the directory isn't found.

func (*Fs) Mkdir

func (f *Fs) Mkdir(ctx context.Context, dir string) (err error)

Mkdir creates the directory if it doesn't exist

func (*Fs) Move

func (f *Fs) Move(ctx context.Context, src fs.Object, remote string) (fs.Object, error)

Move renames a remote file object

func (*Fs) Name

func (f *Fs) Name() string

Name of this fs

func (*Fs) NewObject

func (f *Fs) NewObject(ctx context.Context, remote string) (o fs.Object, err error)

NewObject finds the Object at remote. If it can't be found it returns the error fs.ErrorObjectNotFound.

func (*Fs) Precision

func (f *Fs) Precision() time.Duration

Precision shows whether modified time is supported or not depending on the FTP server capabilities, namely whether FTP server:

• accepts the MDTM command to get file time (fGetTime) or supports MLSD returning precise file time in the list (fLstTime)
• accepts the MFMT command to set file time (fSetTime) or non-standard form of the MDTM command (fSetTime, too) used by VsFtpd for the same purpose (WritingMDTM)

See "mdtm_write" in https://security.appspot.com/vsftpd/vsftpd_conf.html

func (*Fs) Put

func (f *Fs) Put(ctx context.Context, in io.Reader, src fs.ObjectInfo, options ...fs.OpenOption) (fs.Object, error)

Put in to the remote path with the modTime given of the given size

May create the object even if it returns an error - if so will return the object and the error, otherwise will return nil and the error

func (*Fs) PutStream

func (f *Fs) PutStream(ctx context.Context, in io.Reader, src fs.ObjectInfo, options ...fs.OpenOption) (fs.Object, error)

PutStream uploads to the remote path with the modTime given of indeterminate size

func (*Fs) Rmdir

func (f *Fs) Rmdir(ctx context.Context, dir string) error

Rmdir removes the directory (container, bucket) if empty

Return an error if it doesn't exist or isn't empty

func (*Fs) Root

func (f *Fs) Root() string

Root of the remote (as passed into NewFs)

func (*Fs) Shutdown

func (f *Fs) Shutdown(ctx context.Context) error

Shutdown the backend, closing any background tasks and any cached connections.

func (*Fs) String

func (f *Fs) String() string

String returns a description of the FS

type Object

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

Object describes an FTP file

func (*Object) Fs

func (o *Object) Fs() fs.Info

Fs returns the parent Fs

func (*Object) Hash

func (o *Object) Hash(ctx context.Context, t hash.Type) (string, error)

Hash returns the hash of an object returning a lowercase hex string

func (*Object) ModTime

func (o *Object) ModTime(ctx context.Context) time.Time

ModTime returns the modification time of the object

func (*Object) Open

func (o *Object) Open(ctx context.Context, options ...fs.OpenOption) (rc io.ReadCloser, err error)

Open an object for read

func (*Object) Remote

func (o *Object) Remote() string

Remote returns the remote path

func (*Object) Remove

func (o *Object) Remove(ctx context.Context) (err error)

Remove an object

func (*Object) SetModTime

func (o *Object) SetModTime(ctx context.Context, modTime time.Time) error

SetModTime sets the modification time of the object

func (*Object) Size

func (o *Object) Size() int64

Size returns the size of an object in bytes

func (*Object) Storable

func (o *Object) Storable() bool

Storable returns a boolean as to whether this object is storable

func (*Object) String

func (o *Object) String() string

String version of o

func (*Object) Update

func (o *Object) Update(ctx context.Context, in io.Reader, src fs.ObjectInfo, options ...fs.OpenOption) (err error)

Update the already existing object

Copy the reader into the object updating modTime and size.

The new object may have been created if an error is returned

	Host              string               `config:"host"`
