3# PRE-UNLOCK HOOK
4#
5# The pre-unlock hook is invoked before an exclusive lock is
6# destroyed.  Subversion runs this hook by invoking a program
7# (script, executable, binary, etc.) named 'pre-unlock' (for which
8# this file is a template), with the following ordered arguments:
9#
10#   [1] REPOS-PATH   (the path to this repository)
11#   [2] PATH         (the path in the repository about to be unlocked)
12#   [3] USER         (the user destroying the lock)
13#
14# The default working directory for the invocation is undefined, so
15# the program should set one explicitly if it cares.
16#
17# If the hook program exits with success, the lock is destroyed; but
18# if it exits with failure (non-zero), the unlock action is aborted
19# and STDERR is returned to the client.
20
21# On a Unix system, the normal procedure is to have 'pre-unlock'
22# invoke other programs to do the real work, though it may do the
23# work itself too.
24#
25# Note that 'pre-unlock' must be executable by the user(s) who will
26# invoke it (typically the user httpd runs as), and that user must
27# have filesystem-level permission to access the repository.
28#
29# On a Windows system, you should name the hook program
30# 'pre-unlock.bat' or 'pre-unlock.exe',
31# but the basic idea is the same.
32#
33# Here is an example hook script, for a Unix /bin/sh interpreter:
34
35REPOS="$1"
36PATH="$2"
37USER="$3"
38
39# If a lock is owned by a different person, don't allow it be broken.
40# (Maybe this script could send email to the lock owner?)
41
42SVNLOOK=/usr/local/bin/svnlook
43GREP=/bin/grep
44SED=/bin/sed
45
46LOCK_OWNER=`$SVNLOOK lock "$REPOS" "$PATH" | \
47            $GREP '^Owner: ' | $SED 's/Owner: //'`
48
49# If we get no result from svnlook, there's no lock, return success:
50if [ "$LOCK_OWNER" == "" ]; then
51  exit 0
52fi
53# If the person unlocking matches the lock's owner, return success:
54if [ "$LOCK_OWNER" == "$USER" ]; then
55  exit 0
56fi
57
58# Otherwise, we've got an owner mismatch, so return failure:
59echo "Error: $PATH locked by ${LOCK_OWNER}." 1>&2
60exit 1
