Functions ¶
func Cleanup ¶
func Cleanup() error
Cleanup removes the entire process-specific temp directory. Note: After Cleanup(), TempDir() will still return the deleted path. Callers should not use TempDir() after Cleanup(). Note: On Windows, directory deletion may fail if files are still open.
func CreateTemp ¶
CreateTemp creates a temporary file, using the process-specific directory when dir is empty
Types ¶
type Root ¶ added in v0.72.0
Root is a traversal-resistant handle to a directory. It embeds *os.Root (https://pkg.go.dev/os#Root), so every name passed to its methods is confined to the directory. Root adds NewRoot and Join.
func NewRoot ¶ added in v0.72.0
NewRoot creates dir (0700) if necessary and opens it as a Root. Like os.OpenRoot, it returns an error if the directory cannot be opened.
func (*Root) Join ¶ added in v0.72.0
Join validates name and returns it joined to the root directory. It rejects names that escape the root either literally (filepath.IsLocal handles "..", absolute paths, and escapes hidden behind a missing component) or through an existing symlink (the embedded os.Root). A name that does not exist yet is allowed, so the caller can resolve a destination before creating it.
The result is a plain string, so it is not protected against a later symlink swap (TOCTOU): use it to hand a confined path to an external tool, and use the os.Root methods directly for ordinary I/O.
