Variables

var Deadline = 10 * time.Second

Deadline bounds how long one operation waits for a contended lock. A wedged holder must produce a refusal with a legal recovery action, never a hang.

Functions

func With

func With(path string, fn func() error) error

With serializes work across processes and goroutines. The OS releases the file lock if its process exits, so no unsafe stale-lock deletion is needed. Contention past Deadline refuses instead of blocking forever.
