- # 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
