Unlike the other hooks, the default state of this one is to deny the proposed action. The hook must actually exist and return a zero exit value before a revision property modification can happen.</p> <p>If the <code class="literal">pre-revprop-change</code> hook doesn't exist, isn't executable, or returns a nonzero exit value, no change to the property will be made, and anything printed to <code class="filename">stderr</code> is marshalled back to the client.</p> </div> <div class="refsect1" title="Input parameter(s)"> <a id="idp26019984"></a> <h2>Input parameter(s)</h2> <p>The command-line arguments passed to the hook program, in order, are:</p> <div class="orderedlist"> <ol class="orderedlist" type="1"> <li class="listitem"> <p>Repository path</p> </li> <li class="listitem"> <p>Revision whose property is about to be modified</p> </li> <li class="listitem"> <p>Authenticated username attempting the property change</p> </li> <li class="listitem"> <p>Name of the property changed</p> </li> <li class="listitem"> <p>Change description: <code class="literal">A</code> (added), <code class="literal">D</code> (deleted), or <code class="literal">M</code> (modified)</p> </li> </ol> </div> <p>Additionally, Subversion passes the intended new value of the property to the hook program via standard input.</p> </div> <div class="refsect1" title="Common uses"> <a id="idp26029232"></a> <h2>Common uses</h2> <p>Access control; change validation and 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-commit.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-revprop-change.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top">post-commit </td> <td width="20%" align="center"> <a accesskey="h" href="index.html">Home</a> </td> <td width="40%" align="right" valign="top"> post-revprop-change</td> </tr> </table> </div> <div xmlns="" id="vcws-footer"> <hr /> <img src="images/cc-by.png" style="float: right;" /> <p>You are reading <em>Version Control with Subversion</em> (for Subversion 1.8), by Ben Collins-Sussman, Brian W.
