gotchas upgrading from 2.1.6 (!) to 2.4.3 ?
Am upgrading from Zope 2.1.6 (sic!) to 2.4.3. I know 2.5.0 is out but I'm using a VPS so I don't get a choice in version of Zope. As you can guess, I've been out of Zope for a while and noticed some changes. For example, ZPT seems to be a big addition though don't think I'm going to use it. I'm most interested in things that are going to break the migration of my old sites built on 2.1.6 which used products such as SQLSession, SiteAccess and TinyTablesPlus. I've imported these packages into Zope 2.4.3 without problem. Some gotchas I've encountered ~ __no_before_traverse__ no longer works. I seem to get quite a lot of "guarded_getattr" errors. REQUEST is no longer available Anything else in particular I should watch out for ? Stephen. -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net

There are severe memory corruption problems in Python 2.1.1 and Zope 2.4.x (with x<=3).
... Some gotchas I've encountered ~ __no_before_traverse__ no longer works. It was eliminated from ZPublisher (probably to make the code cleaner and because nowadays the hook is used by other useful services, too: Sessions, CookieCrumber, ...).
To suppress SiteAccess AccessRules, you can now use "_SUPPRESS_ACCESSRULE".
I seem to get quite a lot of "guarded_getattr" errors. REQUEST is no longer available I can still use it.
Anything else in particular I should watch out for ? Most essential changes: the security policy is much stricter now. Read Brian's paper on Zope Security (for Zope 2.2).
