Functions ¶

func Unmount ¶

func Unmount(target string) error

Unmount unmounts the target. It does not return an error in case the target is not mounted. In case the target does not exist, the appropriate error is returned.

Types ¶

type OS ¶

type OS interface {
	MkdirAll(path string, perm os.FileMode) error
	RemoveAll(path string) error
	OpenFifo(ctx context.Context, fn string, flag int, perm os.FileMode) (io.ReadWriteCloser, error)
	Stat(name string) (os.FileInfo, error)
	ResolveSymbolicLink(name string) (string, error)
	FollowSymlinkInScope(path, scope string) (string, error)
	CopyFile(src, dest string, perm os.FileMode) error
	WriteFile(filename string, data []byte, perm os.FileMode) error
	Mount(source string, target string, fstype string, flags uintptr, data string) error
	Unmount(target string) error
	LookupMount(path string) (mount.Info, error)
}

OS collects system level operations that need to be mocked out during tests.

type RealOS ¶

type RealOS struct{}

RealOS is used to dispatch the real system level operations.

func (RealOS) CopyFile ¶

func (RealOS) CopyFile(src, dest string, perm os.FileMode) error

CopyFile will copy src file to dest file

func (RealOS) FollowSymlinkInScope ¶

func (RealOS) FollowSymlinkInScope(path, scope string) (string, error)

FollowSymlinkInScope will call symlink.FollowSymlinkInScope.

func (RealOS) LookupMount ¶

func (RealOS) LookupMount(path string) (mount.Info, error)

LookupMount gets mount info of a given path.

func (RealOS) MkdirAll ¶

func (RealOS) MkdirAll(path string, perm os.FileMode) error

MkdirAll will call os.MkdirAll to create a directory.

func (RealOS) Mount ¶

func (RealOS) Mount(source string, target string, fstype string, flags uintptr, data string) error

Mount will call unix.Mount to mount the file.

func (RealOS) OpenFifo ¶

func (RealOS) OpenFifo(ctx context.Context, fn string, flag int, perm os.FileMode) (io.ReadWriteCloser, error)

OpenFifo will call fifo.OpenFifo to open a fifo.

func (RealOS) RemoveAll ¶

func (RealOS) RemoveAll(path string) error

RemoveAll will call os.RemoveAll to remove the path and its children.

func (RealOS) ResolveSymbolicLink ¶

func (RealOS) ResolveSymbolicLink(path string) (string, error)

ResolveSymbolicLink will follow any symbolic links

func (RealOS) Stat ¶

func (RealOS) Stat(name string) (os.FileInfo, error)

Stat will call os.Stat to get the status of the given file.

func (RealOS) Unmount ¶

func (RealOS) Unmount(target string) error

Unmount will call Unmount to unmount the file.

func (RealOS) WriteFile ¶
