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#   [4] TOKEN        (the lock token to be destroyed)
14#   [5] BREAK-UNLOCK (1 if the user is breaking the lock, else 0)
15#
16# The default working directory for the invocation is undefined, so
17# the program should set one explicitly if it cares.
18#
19# If the hook program exits with success, the lock is destroyed; but
20# if it exits with failure (non-zero), the unlock action is aborted
21# and STDERR is returned to the client.
22
23# On a Unix system, the normal procedure is to have 'pre-unlock'
24# invoke other programs to do the real work, though it may do the
25# work itself too.
26#
27# Note that 'pre-unlock' must be executable by the user(s) who will
28# invoke it (typically the user httpd runs as), and that user must
29# have filesystem-level permission to access the repository.
30#
31# On a Windows system, you should name the hook program
32# 'pre-unlock.bat' or 'pre-unlock.exe',
33# but the basic idea is the same.
34#
35# Here is an example hook script, for a Unix /bin/sh interpreter:
36
37REPOS="$1"
38PATH="$2"
39USER="$3"
40TOKEN="$4"
41BREAK="$5"
42
43# If a lock is owned by a different person, don't allow it be broken.
44# (Maybe this script could send email to the lock owner?)
45
46SVNLOOK=/usr/local/bin/svnlook
47GREP=/bin/grep
48SED=/bin/sed
49
50LOCK_OWNER=`$SVNLOOK lock "$REPOS" "$PATH" | \
51            $GREP '^Owner: ' | $SED 's/Owner: //'`
52
53# If we get no result from svnlook, there's no lock, return success:
54if [ "$LOCK_OWNER" = "" ]; then
55  exit 0
56fi
57
58# If the person unlocking matches the lock's owner, return success:
59if [ "$LOCK_OWNER" = "$USER" ]; then
60  exit 0
61fi
62
63# Otherwise, we've got an owner mismatch, so return failure:
64echo "Error: $PATH locked by ${LOCK_OWNER}." 1>&2
65exit 1
