StaleLockPolicy class abstract interface

Decides whether a waiter may reclaim an existing InterProcessLock file whose holder appears to have abandoned it.

Constructors

StaleLockPolicy.age(Duration staleAfter)

Reclaims once the lock file's modified time is older than staleAfter.

const

factory

StaleLockPolicy.never()

Never reclaims; the caller guarantees the holder finishes or fails fast.

const

factory

StaleLockPolicy.processLiveness({required Duration staleAfter})

Reclaims a lock whose recorded process is dead, with an age backstop for a holder that leaked the lock while its process stayed alive (e.g. a hung sibling isolate sharing the PID). Pair with InterProcessLock.acquire's heartbeatInterval so the backstop measures idle time, not work time.
