Users can't edit profile was created by Cluster89

Hello,

I am using: Joomla! 3.6.5 Stable, PHP 5.6 and CB 2.1.2. Users login with JMapMyLDAP.
The problem is, when a user tries to edit his profile and changes anything and saves, he gets following error:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 20972558 bytes) in /var/www/html/dev.sitetest.net/libraries/shmanic/ldap/event/debug.php on line 133

The memory usage before save button click when changing profile (Joomla Debug Console): 40.56 MB (42.530.720 Bytes)

On line 133 is:

Code:

		SHLog::add(
			JText::sprintf(
				'LIB_SHLDAPEVENTDEBUG_DEBUG_11951',
				preg_replace('/\s+/', ' ', var_export($user, true)),
				preg_replace('/\s+/', ' ', var_export($new, true))
			), 11951, JLog::DEBUG, 'ldap'
		);

Memory usage before this line: 53068656 b
Call stack:

Code:

#18 /var/www/html/dev.sitetest.net/index.php(49): JApplicationCms->execute() #19 {main}" 	

Now if I delete this log line 133 I get the error on a totaly different place:
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 20972662 bytes) in /var/www/html/dev.sitetest.net/libraries/joomla/database/driver.php on line 1967.
Anyone has an idea what is going on?

I was able to track down the problem more.
Everytime someone saves, slashes get added to the DB:

"\\\\\\\\\\\\\\\\
\\\\\" $:\$ \\\\\\\\\
\\\\\\\\\\\\\\\\\
\\\\"{\\\\\\\\\\
\\\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\\\\
\\"auth_typ
e\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\" $:\$
\\\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\\\\
\\\\\\\\\\\"LD
AP\\\\\\\\\\\\\
\\\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\\\"
,\\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\\\\
\\\\\\\\\\\\\"a
uth_domai
n\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\\\\
\\\\\\\\\\\\\\""

Now after sometime it gets so much that PHP can't handle it anymore, because of memory issues. Now I need to find out, why it is doing this.

Your LDAP plugin is acting on Joomla save and is where your issue is coming from. I'm guessing there's something in the plugin getting stuck in a loop. Specifically in class SHLdapEventDebug of function onUserBeforeSave. Try putting a return at the top of the onUserBeforeSave function to stop its functionality and see if that resolves it. I recommend contacting the developer of your LDAP plugin for further support. The slashes issue is likely a bad escaping on the params that that plugin is doing before the user is saved.

Hello,
where does CB json_decode the params column (in users table) when it does load a user in usertable::load?

Similar Problem:
www.joomlapolis.com/forum/149-usage/233722-params-field-in-users-to-long-to-be-editable#281770

I have modified now like this and my problem seems to be gone. bindThisUserFromDbArray called shortly after load

Code:

public function bindThisUserFromDbArray( $arr, $oid = null  ) {
		foreach ( $arr as $kk => $v ) {
			$this->$kk		=	$v;
			if (trim($kk) === 'params' && trim($v) !== '') {
				$this->$kk = json_decode($this->$kk);
			}
		}

When the user is saved the param is getting json_encoded again, so it has to be decoded before, or it grows and grows.

Params storage is done in cb.core when storing the userparams field. The loading is done by Joomlas own user object. We use Joomlas own registry API to handle parsing the params for storage. There are also zero issues in my local tests or on our demosite. Nothing should be calling json_decode or json_encode on Joomla user params. They should be passed through Joomlas Registry class, which will handle them accordingly. My guess is your LDAP plugin is not doing that.

hm thanks for your answer.
Yes I agree that json_decode should not be called directly, but I guess I will have no other choice if I can't find the root problem...
Just like the other guy I saw it happen also with the {"admin_style":"","admin_language":"","language":"","editor":"","helpsite":"","timezone":"Europe\/Vienna"}"
but happens very rarely in this case. Thats why I think it might not be the LDAP plugin.
I'll try to find where joomla loads the params from the db and then creates the registry class with it or why it is not doing it in my case.
