Database no longer in debugging toolbar when using Propel on some upgrades

[jestep]

Is there something that changed that would remove the database debugging/icon from the web toolbar? I have a number of legacy sites that no longer have the database icon on the toolbar after updating to 1.5.15. I have 1 propel site that does have it still but I can't see anything different in the configuration files, nothing else changed on these sites. web_debug is set to true in settings.yml, DebugPDO is used in databases.yml, and the controller is set to load the debugging environment. Sites running doctrine are unaffected.

If you mean the SQL queries icon, it works for me.

Sorry, yes sql queries. Screenshots are for different sites on the same server, the config on them is almost identical though.

X.15

The icon will only appear if there are any Doctrine Events:
https://github.com/FriendsOfSymfony1/symfony1/blob/master/lib/plugins/sfDoctrinePlugin/lib/debug/sfWebDebugPanelDoctrine.class.php#L30-L33

I guess the listener of the profiler not registered. This is the callstack for a preConnect event:

This should return the symfony_profiler listener. If something is not set correctly you should get an error here.

    $dbm = sfContext::getInstance()->getDatabaseManager();
    $database = $dbm->getDatabase($dbm->getNames()[0]);
    $profilerListener = $database->getDoctrineConnection()->getListener()->get('symfony_profiler');

I think I had the same issue in the past and solved it by disabling persistent db connections in dev.

    param:
      persistent:
        value:      false
      classname:    DebugPDO

According to Propel docs, persistent connections need to be disabled for correct query counting/logging.
