   3 # PRE-UNLOCK HOOK
   4 #
   5 # The pre-unlock hook is invoked before an exclusive lock is
   6 # destroyed.  Subversion runs this hook by invoking a program
   7 # (script, executable, binary, etc.) named 'pre-unlock' (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 unlocked)
  12 #   [3] USER         (the user destroying 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 destroyed; but
  18 # if it exits with failure (non-zero), the unlock action is aborted
  19 # and STDERR is returned to the client.
  20
  21 # On a Unix system, the normal procedure is to have 'pre-unlock'
  22 # invoke other programs to do the real work, though it may do the
  23 # work itself too.
  24 #
  25 # Note that 'pre-unlock' 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-unlock.bat' or 'pre-unlock.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="$3"
  38
  39 # If a lock is owned by a different person, don't allow it be broken.
  40 # (Maybe this script could send email to the lock owner?)
  41
  42 SVNLOOK=/usr/local/bin/svnlook
  43 GREP=/bin/grep
  44 SED=/bin/sed
  45
  46 LOCK_OWNER=`$SVNLOOK lock "$REPOS" "$PATH" | \
  47             $GREP '^Owner: ' | $SED 's/Owner: //'`
  48
  49 # If we get no result from svnlook, there's no lock, return success:
  50 if [ "$LOCK_OWNER" = "" ]; then
  51   exit 0
  52 fi
  53 # If the person unlocking matches the lock's owner, return success:
  54 if [ "$LOCK_OWNER" = "$USER" ]; then
  55   exit 0
  56 fi
  57
  58 # Otherwise, we've got an owner mismatch, so return failure:
  59 echo "Error: $PATH locked by ${LOCK_OWNER}." 1>&2
  60 exit 1
