# PRE-UNLOCK HOOK

#

# The pre-unlock hook is invoked before an exclusive lock is

# destroyed.  Subversion runs this hook by invoking a program 

# (script, executable, binary, etc.) named 'pre-unlock' (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 unlocked)

#   [3] USER         (the user destroying the lock)

#

# 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 destroyed; but

# if it exits with failure (non-zero), the unlock action is aborted

# and STDERR is returned to the client.

# On a Unix system, the normal procedure is to have 'pre-unlock'

# invoke other programs to do the real work, though it may do the

# work itself too.

#

# Note that 'pre-unlock' 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-unlock.bat' or 'pre-unlock.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 is owned by a different person, don't allow it be broken.

# (Maybe this script could send email to the 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, return success:

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

  exit 0

fi

# If the person unlocking matches the lock's owner, return success:

if [ "$LOCK_OWNER" == "$USER" ]; then

  exit 0

fi

# Otherwise, we've got an owner mismatch, so return failure:

echo "Error: $PATH locked by ${LOCK_OWNER}." 1>&2

exit 1
