It looks like this bug was closed due to lack of feedback from the original poster. I would suggest opening a new collector issue and reference that one if you think it is the same issue (it certainly appears to be on the surface). The collector issue would stand a much better chance of being acted on if you also submit a patch with a cooresponding unittest that fails on Mac OS X with the current implementation. -Casey On Thu, 8 Jul 2004 15:12:13 +1000 (EST) "Terry Kerr" <terry@bizarsoftware.com.au> wrote:

Hi,

I seem to be having problems relating to AccessControl on MacOSX. I have a python product which I previously ran in Zope2.4.3/Python 2.1.3 and have upgraded it to run in Zope2.7.1/Python2.3.3. It runs fine on Linux and FreeBSD, however I get this traceback with some actions within the product on Mac OSX 10.1

Module Products.PageTemplates.Expressions, line 201, in __call__

Module Products.PageTemplates.Expressions, line 189, in _eval

Module Products.PageTemplates.Expressions, line 145, in _eval __traceback_info__: shopper

Module Products.PageTemplates.Expressions, line 340, in restrictedTraverse __traceback_info__: {'path': ['name'], 'TraversalRequestNameStack': []}

SystemError: NULL result without error in PyObject_Call

I narrowed this down to a guarded_getattr() problem in the AccessControl module. One thing I notice is that there is a C and a Python implementation of the access control stuff.

If I explicitly set name='PYTHON' at the beginning of AccessControl/Implementation.py::setImplementation(), my product works fine, so I gather the problem is related to the C implementation.

Has anyone experienced any similar problems on MacOSX?

I notice this related issue in the zope collector, but it was rejected? http://zope.org/Collectors/Zope/232

Should I add another issue to the collector?
