Hi! I just had a very strange problem. I tried some code like this in a Script (Python). The (obvious) error in the code is the html += instead of just html =. These few lines brought the Zope server (and the Browser I used for testing) to a halt: html = '' for letter in 'ABCDEFGHIJKLMNOPQRSTUVWXYZ': html += '|'.join([html, letter]) return html After a very long time I got a Memory Error. I am not really sure whether this qualifies as a bug, and whether it is a Zope bug or a Python bug (the same happens when using the same code from filesystem-based Python). But I'd guess that code fragments in Scripts (Python) should be save enough to not blow the server. Other memory-intensive potentially malicious code like infinite recursions are handled well after all.
