pre-unlock — Notification of a path unlock attempt.
The pre-unlock hook runs whenever
someone attempts to remove a lock on a file. It can be used
to create policies that specify which users are allowed to
unlock particular paths. It's particularly important for
determining policies about lock breakage. If user A locks a
file, is user B allowed to break the lock? What if the lock
is more than a week old? These sorts of things can be
decided and enforced by the hook.
If the pre-unlock hook program
returns a nonzero exit value, the unlock action is aborted
and anything printed to stderr is marshalled back to the
client.
The command-line arguments passed to the hook program, in order, are:
Repository path
Versioned path which is to be unlocked
Authenticated username of the person attempting the unlock
Lock token associated with the lock which is to be removed
1 if the user is attempting to
break the lock; 0 otherwise
