+# PRE-UNLOCK HOOK

+#

+# The pre-unlock hook is invoked before an exclusive lock is

+# destroyed.  Subversion runs this hook by invoking a program 

+# (script, executable, binary, etc.) named 'pre-unlock' (for which

+# this file is a template), with the following ordered arguments:

+#

+#   [1] REPOS-PATH   (the path to this repository)

+#   [2] PATH         (the path in the repository about to be unlocked)

+#   [3] USER         (the user destroying the lock)

+#   [4] TOKEN        (the lock token to be destroyed)

+#   [5] BREAK-UNLOCK (1 if the user is breaking the lock, else 0)

+#

+# The default working directory for the invocation is undefined, so

+# the program should set one explicitly if it cares.

+#

+# If the hook program exits with success, the lock is destroyed; but

+# if it exits with failure (non-zero), the unlock action is aborted

+# and STDERR is returned to the client.

+

+# On a Unix system, the normal procedure is to have 'pre-unlock'

+# invoke other programs to do the real work, though it may do the

+# work itself too.

+#

+# Note that 'pre-unlock' must be executable by the user(s) who will

+# invoke it (typically the user httpd runs as), and that user must

+# have filesystem-level permission to access the repository.

+#

+# On a Windows system, you should name the hook program

+# 'pre-unlock.bat' or 'pre-unlock.exe',

+# but the basic idea is the same.

+#

+# Here is an example hook script, for a Unix /bin/sh interpreter:

+

+REPOS="$1"

+PATH="$2"

+USER="$3"

+

+# If a lock is owned by a different person, don't allow it be broken.

+# (Maybe this script could send email to the lock owner?)

+

+SVNLOOK=/usr/local/bin/svnlook

+GREP=/bin/grep

+SED=/bin/sed

+

+LOCK_OWNER=`$SVNLOOK lock "$REPOS" "$PATH" | \

+            $GREP '^Owner: ' | $SED 's/Owner: //'`

+

+# If we get no result from svnlook, there's no lock, return success:

+if [ "$LOCK_OWNER" = "" ]; then

+  exit 0

+fi

+

+# If the person unlocking matches the lock's owner, return success:

+if [ "$LOCK_OWNER" = "$USER" ]; then

+  exit 0

+fi

+

+# Otherwise, we've got an owner mismatch, so return failure:

+echo "Error: $PATH locked by ${LOCK_OWNER}." 1>&2

+exit 1
