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
37 REPOS="$1"
38 PATH="$2"
39 USER="$3"
40
41 # If a lock is owned by a different person, don't allow it be broken.
42 # (Maybe this script could send email to the lock owner?)

50
51 # If we get no result from svnlook, there's no lock, return success:
52 if [ "$LOCK_OWNER" = "" ]; then
53 exit 0
54 fi
55
56 # If the person unlocking matches the lock's owner, return success:
57 if [ "$LOCK_OWNER" = "$USER" ]; then
58 exit 0
59 fi
60
61 # Otherwise, we've got an owner mismatch, so return failure:
62 echo "Error: $PATH locked by ${LOCK_OWNER}." 1>&2
63 exit 1
