3# PRE-LOCK HOOK
4#
5# The pre-lock hook is invoked before an exclusive lock is
6# created.  Subversion runs this hook by invoking a program
7# (script, executable, binary, etc.) named 'pre-lock' (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 locked)
12#   [3] USER         (the user creating the lock)
13#   [4] COMMENT      (the comment of the lock)
14#   [5] STEAL-LOCK   (1 if the user is trying to steal the lock, else 0)
15#
16# If the hook program outputs anything on stdout, the output string will
17# be used as the lock token for this lock operation.  If you choose to use
18# this feature, you must guarantee the tokens generated are unique across
19# the repository each time.
20#
21# The default working directory for the invocation is undefined, so
22# the program should set one explicitly if it cares.
23#
24# If the hook program exits with success, the lock is created; but
25# if it exits with failure (non-zero), the lock action is aborted
26# and STDERR is returned to the client.
27
28# On a Unix system, the normal procedure is to have 'pre-lock'
29# invoke other programs to do the real work, though it may do the
30# work itself too.
31#
32# Note that 'pre-lock' must be executable by the user(s) who will
33# invoke it (typically the user httpd runs as), and that user must
34# have filesystem-level permission to access the repository.
35#
36# On a Windows system, you should name the hook program
37# 'pre-lock.bat' or 'pre-lock.exe',
38# but the basic idea is the same.
39#
40# Here is an example hook script, for a Unix /bin/sh interpreter:
41
42REPOS="$1"
43PATH="$2"
44USER="$3"
45COMMENT="$4"
46STEAL="$5"
47
48# If a lock exists and is owned by a different person, don't allow it
49# to be stolen (e.g., with 'svn lock --force ...').
50
51# (Maybe this script could send email to the lock owner?)
52SVNLOOK=/usr/local/bin/svnlook
53GREP=/bin/grep
54SED=/bin/sed
55
56LOCK_OWNER=`$SVNLOOK lock "$REPOS" "$PATH" | \
57            $GREP '^Owner: ' | $SED 's/Owner: //'`
58
59# If we get no result from svnlook, there's no lock, allow the lock to
60# happen:
61if [ "$LOCK_OWNER" = "" ]; then
62  exit 0
63fi
64
65# If the person locking matches the lock's owner, allow the lock to
66# happen:
67if [ "$LOCK_OWNER" = "$USER" ]; then
68  exit 0
69fi
70
71# Otherwise, we've got an owner mismatch, so return failure:
72echo "Error: $PATH already locked by ${LOCK_OWNER}." 1>&2
73exit 1
