remove a lock on a file. It can be used to create policies
that specify which users are allowed to unlock particular
paths. It's particularly important for determining policies
about lock breakage. If user A locks a file, is user B
allowed to break the lock? What if the lock is more than a
week old? These sorts of things can be decided and enforced
by the hook.</p><p>If the pre-unlock hook program returns a non-zero exit
value, the unlock action is aborted and anything printed to
stderr is marshalled back to the client.</p></div><div class="refsect1" lang="en" xml:lang="en"><a id="id429065"></a><h2>Input Parameter(s)</h2><p>The command-line arguments passed to the hook program,
in order, are:</p><div class="orderedlist"><ol type="1"><li><p>repository path</p></li><li><p>versioned path which is to be locked</p></li><li><p>authenticated username of the person attempting the
lock</p></li></ol></div></div><div class="refsect1" lang="en" xml:lang="en"><a id="id429103"></a><h2>Common Uses</h2><p>access control</p></div></div><div class="navfooter"><hr /><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="svn.ref.reposhooks.post-lock.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="svn.ref.reposhooks.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="svn.ref.reposhooks.post-unlock.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">post-lock </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> post-unlock</td></tr></table></div></body></html>
