Hi ! I have a question about zope's python limitation. ZopeBook is say that zope's py is limited. Limited: ranges are not be to loo long, cycles (for, until) are limited, etc. I want to create two unlimited, long process. The first is an database content checker: it is check many records in an interval (1 year, 1 month, etc). So it is very slow, with many db operations. 1: The Zope is really limiting this process ? How to do it ? Terminate the thread ? 2: How to prevent the process double starting (with refresh in the browser ?) If I set a value in the session, that is good, but who delete it, when the process-or request is terminted by an exception, or zope-s termination signal ? 3: How to show the state of process ? a.) .write(), .flush(), long-long html with js tags what rewrite an readonly form input-text with actual percent ? b.) centrally stored actual result with window.setinterval(n), and periodic page reloading ? Or I walk in wrong way, I must create an outer product (a py file) with native commands, and zope only check this ? Thanx for help: ft
