For some reason, in my product, the __del__(self) is not being called when I delete an instance of it.. I currently have it defined as:
def __del__(self): raise "DEBUG", "TEST"
Just to see what is going on... Any ideas?
First, exceptions raised in __del__ are ignored. See the Python Language Reference, section 3.3.1: http://www.python.org/doc/current/ref/customization.html#l2h-127 Second, __del__ is not called when your object is 'deleted' from the managment interface. __del__ is called when the instance is destroyed in memory. In the usual case this is when the instance's ref-count drops to zero. In the case of Zope objects that are in memory ('activated') when the ref-count of an instance drops to one, then the only object that references the instance is the object cache itself; in this case the cache deletes its reference to the instance (dropping the ref-count to zero) and the object's __del__ method is called. This is way low-level stuff. What you are looking for is manage_beforeDelete.
