Joomla 3 is now only getting security fixes
NP, I assume it doesn't work on J4 either, I'll test and submit a new bug report ...
were you able to replicate this in joomla 4?
No, I haven't had time, had to fall back on building a cli app/cron job to
get a reliable solution in place. The daemon is on the backlog, maybe after
we port the whole package to J4.

I just looked the code, the issue valid for both J3 and j4.

It should be full class name, with namespace.

Incomplete code, apologies.
This is the correct code to reproduce:
getQuery(true); $query->select('COUNT(*) AS count')->from($db->quoteName('#__content')); $db->setQuery($query); $result = $db->loadObject(); $this->out("pages: " . $result->count); } } class LaunchDaemon extends JApplicationDaemon { public $name='test'; public function doExecute() { $db = JFactory::getDbo(); $query = $db->getQuery(true); $query->select('COUNT(*) AS count')->from($db->quoteName('#__content')); $db->setQuery($query); $result = $db->loadObject(); $this->out("pages: " . $result->count); } } $options = getopt("d"); try { if (array_key_exists('d', $options)) JApplicationDaemon::getInstance('LaunchDaemon')->execute(); else JApplicationCli::getInstance('LaunchCLI')->execute(); } catch (Exception $e){ echo $e->getMessage() . "\n"; } ?>This comment was created with the J!Tracker Application at issues.joomla.org/tracker/joomla-cms/39533.
