| # 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) |
| # [4] TOKEN (the lock token to be destroyed) |
| # [5] BREAK-UNLOCK (1 if the user is breaking the lock, else 0) |
| # |
| # 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="$3" |
| |
| # If a lock is owned by a different person, don't allow it be broken. |
| # (Maybe this script could send email to the lock owner?) |
| |
| SVNLOOK=/usr/bin/svnlook |
| GREP=/bin/grep |
| SED=/bin/sed |
| |
| LOCK_OWNER=`$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 |
