| 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="$3" |
||
| 45 | |||
| 46 | # If a lock exists and is owned by a different person, don't allow it |
||
| 47 | # to be stolen (e.g., with 'svn lock --force ...'). |
||
| 48 | |||
| 49 | # (Maybe this script could send email to the lock owner?) |
||
| 50 | SVNLOOK=/usr/local/bin/svnlook |
||
| 51 | GREP=/bin/grep |
||
| 52 | SED=/bin/sed |
||
| 53 | |||
| 54 | LOCK_OWNER=`$SVNLOOK lock "$REPOS" "$PATH" | \ |
||
| 55 | $GREP '^Owner: ' | $SED 's/Owner: //'` |
||
| 56 | |||
| 57 | # If we get no result from svnlook, there's no lock, allow the lock to |
||
| 58 | # happen: |
||
| 59 | if [ "$LOCK_OWNER" = "" ]; then |
||
| 60 | exit 0 |
||
| 61 | fi |
||
| 62 | |||
| 63 | # If the person locking matches the lock's owner, allow the lock to |
||
| 64 | # happen: |
||
| 65 | if [ "$LOCK_OWNER" = "$USER" ]; then |
||
| 66 | exit 0 |
||
| 67 | fi |
||
| 68 | |||
| 69 | # Otherwise, we've got an owner mismatch, so return failure: |
||
| 70 | echo "Error: $PATH already locked by ${LOCK_OWNER}." 1>&2 |
||
| 71 | exit 1 |
