This is a possible bug, so: Zope 2.5.1 Python 2.1.1 I know this isn't the latest python but right now this is just for inhouse development. On with the bug! I noticed I had 16k (yes, thousands) of Acquisition.ImplicitAcquirerWrapper objects. Since this site is hardly used, this seemed odd. After spending a few hours isolating the issue, here's how I can reproduce it. Create a folder in the root, call it "A". Create a dtml document (call it "B") in the folder with this simple body: <html><body> <dtml-var title_or_id> </body></html> Change security on "A". In particular, change "Access contents information" to: acquire: no, anon: no, authenitcated: yes, manager: yes, owner: yes. And save changes. From one browser window, visit "/A/B". In a separate window, open the control panel's debug window. Each time you visit /A/B, the number of Acquisition.ImplicitAcquirerWrapper objects goes up by about three. Repeat until it gets boring. Can anyone else reproduce this? And is it a bug? Charlie Reiman
