# 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) | |
# | |
# 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 |
