pre-revprop-change — Notification of a revision property change attempt.
The pre-revprop-change hook is run immediately prior to the modification of a revision property when performed outside the scope of a normal commit. Unlike the other hooks, the default state of this one is to deny the proposed action. The hook must actually exist and return a zero exit value before a revision property modification can happen.
If the pre-revprop-change hook doesn't
exist, isn't executable, or returns a nonzero exit value, no
change to the property will be made, and anything printed
stderr is marshalled back to the
The command-line arguments passed to the hook program, in order, are:
Revision whose property is about to be modified
Authenticated username attempting the property change
Name of the property changed
Additionally, Subversion passes the intended new value of the property to the hook program via standard input.
