- New restricted execution architecture
A note about this for those who have run afoul of restrictions on builtins such as 'list', 'map', and 'range' in Scripts and DTML Python expressions: In the new architecture, there are (by default) no attempts to protect the system against excessive CPU or memory utilization. Unless you explicitly turn on such limits (not implemented yet), anyone who has permission to write DTML or Scripts in your Zope can accidentally or deliberately consume all available resources with infinite loops or huge data structures. Realistically, they could before, they just had to be slightly more creative. Cheers, Evan @ digicool
