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 to
stderr is marshaled back to the
client.
The command-line arguments passed to the hook program, in order, are:
Repository path
Revision whose property is about to be modified
Authenticated username attempting the property change
Name of the property changed
Change description: A
(added), D
(deleted), or
M
(modified)
Additionally, Subversion passes the intended new value of the property to the hook program via standard input.
