Is there a way to limit the size of aggregator items when the source site provides only a full-text RSS feed?

This one's weird. I use a URL mask for my site's rss feed. Call it: http://mydomain/cms/rss.xml

Something or someone keeps pinging http://mydomain/cms/rss.xml/ts and that generates the following error:

mysql_fetch_object(): supplied argument is not a valid MySQL result resource in /home/xxx/public_html/cms/includes/database.mysql.inc on line 136.

Am trying to get a handle on security issues and am wondering if code run from the PHP input filter, nodes, and/or php blocks is executed with susexec or if the code is executed as nobody?

What is the functions that create the $primary_links variable

I need to know for edit the way of creating

Can anyone help me

Thank you

I would like to prevent users from seeing a navigation menu block and then individual menu items based on what user role they have. The only way I see to do that is to thow in a php statement drupal will check before displaying the block. I still haven't seen how to limit access to individual links. So if someone will point me in the right direction within the interface to do these things or will tell me the variable in which drupal stores it's user roles I would appreciate it.

Is there a way to prevent nodes of specific node type to be not
indexed and searched by the core search module?
