Functions ¶

func EnsureInJail ¶

func EnsureInJail(jailPath, p string) string

EnsureInJail returns a path that resides inside jail when possible.

If the path is already inside jail, the cleaned absolute form is returned. Otherwise a path under jail is returned by appending the base name of the path.

func EnsureInJailFor ¶

func EnsureInJailFor(jailPath, p string) string

EnsureInJailFor is a test-friendly helper that mirrors EnsureInJail but accepts paths written with forward slashes.

It converts both jail and p using filepath.FromSlash before applying the EnsureInJail logic. Use this from tests when expected values are easier to express using POSIX-style literals.

func IsInJail ¶

func IsInJail(jailPath, rel string) bool

IsInJail reports whether the provided path resides within the jail boundary.

If jail is empty, the function returns true (no boundary). Relative paths always are in the jail.

func IsJailed ¶

func IsJailed(j Jailed) bool

IsJailed reports whether j has a non-empty jail configured.

func RemoveJailPrefix ¶

func RemoveJailPrefix(jailPath, path string) string

RemoveJailPrefix removes the jail prefix from a path and returns an absolute path.

Types ¶

type Jailed ¶

type Jailed interface {
	// GetJail returns the current jail root.
	GetJail() string
	// SetJail updates the current jail root.
	SetJail(jail string) error
}

Jailed describes components that can report and update a jail root.

Implementations should treat an empty jail as "not jailed".
