Looking at the relevant *Acquisition.c files, both implementations of aq_inContextOf(2.7.6 & 2.8.0b2) are identical. The implementation of macros used in this method (isWrapper, WRAPPER, and OBJECT) are also identitcal, there being nothing else immediately obvious that looks like it could have been implemented differently there.

Andreas Jung wrote: According to Jim ZClasses are working. A possibly isolated bug in ZClasses is bad but there are in general lots of such bugs in Zope. So > this is not a release stopper for me now. As far as I can see this is either a serious bug with respect to ZClasses in that they just don't work, or something I'm not doing quite right WRT Zope 2.8. My understanding from discussions on zope-dev was that 'ZClasses not working' was a blocker for a release of Zope 2.8.0 final? As an aside, I have tried this on an older Red Hat 32bit linux box and reproduced the same problem, so it doesn't appear to be a 64bit specific problem as I indicated it could be in my previous email. We have discussed ZClasses already and about how ZClasses can be maintained in the future. Since I see little commitment to ZClasses (except from Jim) ZClasses are not really a blocker for *this* 2.8.0 release. We defered this release already a bunch of times and it is now time to get 2.8.0 with Five and MVCC support to people. This is much, much more important for Zope than having to care about ZClasses. People can stick with Zope 2.7 if there is a problem for them with ZClasses in the hope that someone fixes outstanding ZClasses in a further 2.8 release. I don't care getting some beatings for my opinon that ZClasses are a neat ancient toy but not the tool of choice for nowadays Zope applications. We need a strong ZODB with MVCC and we need Five to bridge the world to Zope 3. And therefore ZClasses are absolutely not a reason to block the 2.8.0 release. We are currently using ZClasses, but also really want to be able to use MVCC. I am happy to help out where possible to get ZClasses going in 2.8 if I can get some guidance as to how to go about it. It looks to be a reasonably 'intricate' problem. At the end of the day, I'm actually not concerned about which release this fix (if needed) gets into. The most important thing from my PoV is resolving this for a version of Zope 2.8(+) (even just a branch) soon. I agree that there is a lot of 'good' in Zope 2.8 that should be made available to the wider community in the form of a final release ASAP.

ZClass problem in 2.8 (Was: Re: [Zope-dev] Upcoming Zope 2.8 release)
Andreas Jung wrote: <[EMAIL PROTECTED]> wrote: What about the ZClasses? Jim fixed them (hopefully :-)) They don't work for me in 2.8... :-( I can't shake a new permission problem when trying to add a ZClass instance in 2.8b2. This is a 2.8 specific problem as the same process works in 2.7.6. For reference, the recently enabled tests for ZClasses all pass fine. This is a problem wether python or C security control is enabled via zope.conf. Also this was always tried with a 'fresh' ZODB. From a bit of digging through the code it seems there is a difference comes about in the call on line 166 of AccessControl.User inside _check_context : return object.aq_inContextOf(context, 1) In Zope 2.8 it returns 0, in 2.76 it returns 1 with the steps below. I don't know how to even start to try to debug inside this C based method? Below are the steps I used to reproduce this problem. This was on a Fedora Core 3 x86_64 server with a fresh Zope & Python compile : - Open the ZMI and login as a user with 'Manager' permissions. - Goto : /Control_Panel/Products/ - Add a new Product 'AAA' - Go to the Product : /Control_Panel/Products/AAA/ - Add a new 'Z Class' : id=ZZZ title=ZZZ meta type=ZZZ 'Create Constructor objects' checked 'Included standard Zope persistent object base classes' checked. - Goto the Root Folder - Goto the Security Tab - Give 'Manager' permission to 'Add ZZZs' - Goto the Root Folder - Try to add an instance of a 'ZZZ': - Zope 2.7.6 succeeds no problem. - Zope 2.8.0-b2 (and b1) you get a http auth login form come up. - You get the same behaviours with Python 2.3.5 and 2.4.1. I also tried a quick hack to make the above method always return 1 in Zope 2.8, but another error is then encountered whilst trying to add the ZClass instance : * Module ZPublisher.Publish, line 187, in publish_module_standard * Module ZPublisher.Publish, line 144, in publish * Module ZPublisher.Publish, line 107, in publish * Module Zope2.App.startup, line 248, in recordMetaData * Module OFS.Traversable, line 104, in getPhysicalPath * Module App.FactoryDispatcher, line 90, in __getattr__ AttributeError: getPhysicalPath I didn't see anything different you 'need' to do with 2.8 WRT ZClasses for this to work, but I suppose I could have missed something! One other note is that I have also only been able to try this on 64 bit platforms (Solaris 10 and FC3 as above). Thanks for any help. I hope this can be resolved before 2.8 goes final!
