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 | |
---|
42 | REPOS="$1" |
---|
43 | PATH="$2" |
---|
44 | USER="$3" |
---|
45 | |
---|
46 | # If a lock exists and is owned by a different person, don't allow it |
---|
47 | # to be stolen (e.g., with 'svn lock --force ...'). |
---|
48 | |
---|
49 | # (Maybe this script could send email to the lock owner?) |
---|
50 | SVNLOOK=/usr/local/bin/svnlook |
---|

57 | # If we get no result from svnlook, there's no lock, allow the lock to |

59 | if [ "$LOCK_OWNER" = "" ]; then |

---|

66 | exit 0 |
