in "ZODB/cPersistence.c". >2) where is the code which handles the caching of the objects? in "ZODB/cPickleCache.c" >3) is it possible to disable caching of some object? No, but you can (in most cases) flush it again by calling its "_p_deactivate" method. You can always do it by assigning "None" to "_p_changed", but this is highly unsafe. You should not do it (unless you really know what you are doing). >4) when an _v_ attribute is removed, what code of the object/attribute >itself is called? The object's "__del__" method (if defined). This means the object that was bound to the "_v_" attribute not the object that had the "_v_attribute". -- Dieter _______________________________________________ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
