This is a good point... Not to worry, however, because the default configuration of the session tracking stuff is going to use in-memory storage. Berkeley DB will not need to be (and won't be) distributed with Zope. The session manager will be capable of using nonundo databases (like one based on BerkeleyStorage/BerkeleyDB), but a nonundo database won't be required to make use of it. When you want to use it, you will be able to pick and choose from nonundo storage implementations including BerkeleyDB. ----- Original Message ----- From: "Toby Dickenson" <mbel44@dial.pipex.net> To: <zope-dev@zope.org>; <chrism@digicool.com> Cc: "James Wilson" <jwilson@geminidataloggers.com> Sent: Thursday, October 12, 2000 10:04 AM Subject: [Zope-dev] SessionManager, BerkeleyDB, and license compatability I understand from the SessionTracking wiki that this product may use BerkeleyDB http://www.zope.org/Wikis/DevSite/Projects/CoreSessionTracking/CurrentStatus The BerkeleyDB license at http://www.sleepycat.com/licensing.html indicates that it may only be distributed free of charge with software that is 'freely available and redistributable by others'. We are currently using Zope to develop an application that does not fall into this category. It would be a serious problem for us if Zope's core had a dependency on code with this type of license.
