Functions ¶

func Copy ¶

func Copy(opts CopyOptions) (err error)

Copy creates an exact file copy. The operation fails if the source file is modified concurrently.

func EnsureRelDir ¶

func EnsureRelDir(base, path string, perm os.FileMode) (string, error)

EnsureRelDir creates a directory if and only if it is a subdirectory of base. The base directory must exist. Path may be an absolute path.

On success the cleaned path to the created directory is returned.

If path does not resolve to a subdirectory of base the directory is not created and the function merely returns the path.

func MakeAvailableDir ¶

func MakeAvailableDir(g StringIter) (string, error)

func RenameToAvailableName ¶

func RenameToAvailableName(oldpath string, g StringIter) (string, error)

RenameToAvailableName attempts to rename oldpath to a path produced by g. The used destination path is returned.

func SameStat ¶

func SameStat(a, b string) (bool, error)

SameStat checks whether two paths point to the same file.

Types ¶

type CopyOptions ¶

type CopyOptions struct {
	SourcePath         string
	SourceFlags        int
	SourceMode         os.FileMode
	SourceModePreserve bool

	DestPath  string
	DestFlags int
	DestMode  os.FileMode
	DestSync  bool
}

type FileChanges ¶

type FileChanges []string

func DescribeChanges ¶

func DescribeChanges(a, b os.FileInfo) FileChanges

DescribeChanges produces a list of changes detected between the two given FileInfo instances.

func (FileChanges) Empty ¶

func (c FileChanges) Empty() bool

func (FileChanges) Err ¶

func (c FileChanges) Err() error

type StringIter ¶

type StringIter interface {
	Next() (string, bool)
}
