RE: [Zope] how much does changing a property add to data.fs??

-----Original Message----- From: zope-admin@zope.org [mailto:zope-admin@zope.org]On Behalf Of Robert Rottermann

I was just wondering how changing attributes of an object does change the data.fs size. Is it only the changed attribute that is added to the end of data.fs or is the whole object copied???

I would assume the first. Is that so?

Based on my testing during developing the caching stuff for Photo, it appears that any change to the object adds a complete new copy of the object. When I just set _p_changed = 1, without even changing a property, Data.fs increased by the size of the image plus a bit. Of course, the ZC guys and probably others can verify this for sure. _______________________ Ron Bickers Logic Etc, Inc.
