# 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 |
# |
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 created; but |
18 |
# if it exits with failure (non-zero), the lock action is aborted |
19 |
# and STDERR is returned to the client. |
20 |
|
21 |
# On a Unix system, the normal procedure is to have 'pre-lock' |
22 |
# invoke other programs to do the real work, though it may do the |
23 |
# work itself too. |
24 |
# |
25 |
# Note that 'pre-lock' 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-lock.bat' or 'pre-lock.exe', |
31 |
# but the basic idea is the same. |
32 |
# |
33 |
# Here is an example hook script, for a Unix /bin/sh interpreter: |
34 |
|
35 |
REPOS="$1" |
36 |
PATH="$2" |
37 |
USER="$3" |
38 |
|
39 |
# If a lock exists and is owned by a different person, don't allow it |
40 |
# to be stolen (e.g., with 'svn lock --force ...'). |
41 |
|
42 |
# (Maybe this script could send email to the lock owner?) |
43 |
SVNLOOK=/usr/local/bin/svnlook |

LOCK_OWNER=`$SVNLOOK lock "$REPOS" "$PATH" | \ |
48 |
$GREP '^Owner: ' | $SED 's/Owner: //'` |
49 |
|
50 |
# If we get no result from svnlook, there's no lock, allow the lock to |
51 |
# happen: |
52 |
if [ "$LOCK_OWNER" = "" ]; then |
53 |
exit 0 |
54 |
fi |
55 |
|
56 |
# If the person locking matches the lock's owner, allow the lock to |
57 |
# happen: |
58 |
if [ "$LOCK_OWNER" = "$USER" ]; then |
59 |
exit 0 |
60 |
fi |
61 |
|
62 |
# Otherwise, we've got an owner mismatch, so return failure: |
