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