Under 2.11, run as:: $ PYTHONPATH=lib/python /path/to/python2.4 iter_results_record.py Under 2.12, run as:: $ bin/allpy iter_results_record.py Note that the script runs without errors under both versions for me: likely the security machinery isn't actually being wired up.

Hmmm, I would file it as missing functionality in 2.12. The bug may be due to changes in the supported version of Python (2.4 for Zope < 2.12, 2.6 for 2.12).

I don't know about this tp_iter slot, but adding the following
DocTest to the Record tests.py will pass:
def test_RecordIteration():
"""
Creating a record
>>> r = P(('zx', 81 , 1.23))
We can iterate over a record:
>>> [i for i in r]
['zx', 81, 1.23]
"""

Re: [Zope] Iteration over columns in ZSQLMethod result not working in Zope 2.12.13
To answer part of my own question: ZSQLMethod column iteration went away with 2.12. Up until Zope 2.11.7 still had this feature available with no deprecation messages logged when using this feature. Should I file a bug for missing deprecation messages in 2.11 or for missing functionality in 2.12 ? - Andreas ___ Zope maillist - Zope@zope.org https://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope-dev )

Although that makes the planned upgrade from Zope 2.10 to 2.12 a real pain because I use a lot of the following : result = context.someZSQLMethod() names = result.names() dataForTemplate = dict(zip(names,result[0])) dataForTemplate['addingSomeMoreData'] = 'datadata' return context.comeTemplate(data=dataForTemplate) When did the iteration feature go away ? Must have missed the deprecation process. - Andreas ___ Zope maillist - Zope@zope.org https://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope-dev )
