+# PRE-LOCK HOOK
+#
+# The pre-lock hook is invoked before an exclusive lock is
+# created. Subversion runs this hook by invoking a program
+# (script, executable, binary, etc.) named 'pre-lock' (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 locked)
+# [3] USER (the user creating the lock)
+#
+# 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 created; but
+# if it exits with failure (non-zero), the lock action is aborted
+# and STDERR is returned to the client.
+
+# On a Unix system, the normal procedure is to have 'pre-lock'
+# invoke other programs to do the real work, though it may do the
+# work itself too.
+#
+# Note that 'pre-lock' 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-lock.bat' or 'pre-lock.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="$3"
+
+# If a lock exists and is owned by a different person, don't allow it
+# to be stolen (e.g., with 'svn lock --force ...').
+
+# (Maybe this script could send email to the lock owner?)
+SVNLOOK=/usr/local/bin/svnlook
+GREP=/bin/grep
+SED=/bin/sed
+
+LOCK_OWNER=`$SVNLOOK lock "$REPOS" "$PATH" | \
+ $GREP '^Owner: ' | $SED 's/Owner: //'`
+
+# If we get no result from svnlook, there's no lock, allow the lock to
+# happen:
+if [ "$LOCK_OWNER" = "" ]; then
+ exit 0
+fi
+
+# If the person locking matches the lock's owner, allow the lock to
+# happen:
+if [ "$LOCK_OWNER" = "$USER" ]; then
+ exit 0
+fi
+
+# Otherwise, we've got an owner mismatch, so return failure:
+echo "Error: $PATH already locked by ${LOCK_OWNER}." 1>&2
+exit 1
