Upgrade Notes

  • The default setting disables the feature of ignoring the consecutive click events if it happens too close to the previous one (within 390 milliseconds). This feature is used to prevent the denial-of-service attack and the user's clicking twice before a long operation returns. However, it causes some confusion for the unit test (if the click rate is too high), so it is disabled by default. To enable it, specify the following in zk.xml.
    <client-config>
         <click-filter-delay>390</click-filter-delay>
    </client-config>
