5 # The pre-lock hook is invoked before an exclusive lock is
\r
6 # created. Subversion runs this hook by invoking a program
\r
7 # (script, executable, binary, etc.) named 'pre-lock' (for which
\r
8 # this file is a template), with the following ordered arguments:
\r
10 # [1] REPOS-PATH (the path to this repository)
\r
11 # [2] PATH (the path in the repository about to be locked)
\r
12 # [3] USER (the user creating the lock)
\r
13 # [4] COMMENT (the comment of the lock)
\r
14 # [5] STEAL-LOCK (1 if the user is trying to steal the lock, else 0)
\r
16 # If the hook program outputs anything on stdout, the output string will
\r
17 # be used as the lock token for this lock operation. If you choose to use
\r
18 # this feature, you must guarantee the tokens generated are unique across
\r
19 # the repository each time.
\r
21 # The default working directory for the invocation is undefined, so
\r
22 # the program should set one explicitly if it cares.
\r
24 # If the hook program exits with success, the lock is created; but
\r
25 # if it exits with failure (non-zero), the lock action is aborted
\r
26 # and STDERR is returned to the client.
\r
28 # On a Unix system, the normal procedure is to have 'pre-lock'
\r
29 # invoke other programs to do the real work, though it may do the
\r
32 # Note that 'pre-lock' must be executable by the user(s) who will
\r
33 # invoke it (typically the user httpd runs as), and that user must
\r
34 # have filesystem-level permission to access the repository.
\r
36 # On a Windows system, you should name the hook program
\r
37 # 'pre-lock.bat' or 'pre-lock.exe',
\r
38 # but the basic idea is the same.
\r
40 # Here is an example hook script, for a Unix /bin/sh interpreter:
\r
46 # If a lock exists and is owned by a different person, don't allow it
\r
47 # to be stolen (e.g., with 'svn lock --force ...').
\r
49 # (Maybe this script could send email to the lock owner?)
\r
50 SVNLOOK=/usr/local/bin/svnlook
\r
54 LOCK_OWNER=`$SVNLOOK lock "$REPOS" "$PATH" | \
\r
55 $GREP '^Owner: ' | $SED 's/Owner: //'`
\r
57 # If we get no result from svnlook, there's no lock, allow the lock to
\r
59 if [ "$LOCK_OWNER" = "" ]; then
\r
63 # If the person locking matches the lock's owner, allow the lock to
\r
65 if [ "$LOCK_OWNER" = "$USER" ]; then
\r
69 # Otherwise, we've got an owner mismatch, so return failure:
\r
70 echo "Error: $PATH already locked by ${LOCK_OWNER}." 1>&2
