[Zope-dev] aq_inContextOf/can anyone explain this zmonitor log?
Hi, I just experienced some very weird behaviour from aq_inContextOf while I was trying to get Cut and Paste to work (I had to trace to the whole security stuff to do this, and read the C source for the acquisition stuff the figure out what aq_inContextOf does of course... thanks for having such a great, consistent, mature and well-documented design Zope-guys...) oh, btw, Copy Paste seems to work only for objects that have their User Source at the / level because of the behaviour of inContextOf. well, here's the log: Python 1.5.2 (#5, Aug 10 2000, 15:45:20) [GCC 2.95.2 19991024 (release)] Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam Welcome to secure_monitor_channel connected 127.0.0.1:2625 at 859f680 import Zope import Zope app=Zope.app() app=Zope.app() iee=app.iee iee=app.iee doc1=app.iee.doc1 doc1=app.iee.doc1 doc1.aq_inContextOf(iee) doc1.aq_inContextOf(iee) 0 doc1.aq_inContextOf(app) doc1.aq_inContextOf(app) 1 doc1.aq_inContextOf(app.iee) doc1.aq_inContextOf(app.iee) 0 iee.doc1.aq_inContextOf(app.iee) iee.doc1.aq_inContextOf(app.iee) 0 iee.doc1.aq_inContextOf(iee) iee.doc1.aq_inContextOf(iee) 1 app.iee.doc1.aq_inContextOf(iee) app.iee.doc1.aq_inContextOf(iee) 0 app.iee.doc1.aq_inContextOf(app.iee) app.iee.doc1.aq_inContextOf(app.iee) 0 doc1.aq_inContextOf(iee) doc1.aq_inContextOf(iee) 0 doc1=iee.doc1 doc1=iee.doc1 doc1.aq_inContextOf(iee) doc1.aq_inContextOf(iee) 1 doc1.aq_inContextOf(app.iee) doc1.aq_inContextOf(app.iee) 0 doc1=app.iee.doc1 doc1=app.iee.doc1 doc1.aq_inContextOf(app.iee) doc1.aq_inContextOf(app.iee) ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

[Zope-dev] Caching problems
Hi,
I have a problem with a class I wrote where I have a list as an
attribute of the class. When I append something to that list, it stays
there at first, but only until I restart Zope. It disappears (==is set
to the value I assigned to it in __init__) and reappears as well when
I hit reload a few times very quickly. Whenever I flush the cache it
disappears immediately. There seems to be no transaction registered by
Zope, because it doesn't show up under 'Undo'. I observed this both
thru a dtml page and a debugging function written in python.
I attached the code below, the method and attributes I'm talking about
are IEEShare.read_access_roles, IEEShare.write_access_roles and
IEEShare.add_user_access()
The problem exists with both Zope 2.2.0 and 2.2.1b1. I'm running
2.2.1b1 right now on a SuSE Linux 6.4 default installation. (standard libc,
threads etc.)
Both versions of Zope are compiled from source.

[Zope-dev] ZPatterns, Transactions, _register/_unregister
Hi,
I've encountered some weird behaviour in the ZPatterns Transactional class when
I was trying to write a User Source for the Login Manager Product.
I'm using Zope 2.2.0 with LoginManager 0.8.7a1 and ZPatterns 0.4.1snap1
The problem is that _unregister seems to be trying to delete the _v_registered
attribute of an object that doesn't have it set whenever I return None from
authenticateUser(). The weird thing is that the object seems to be
_register()ed and _v_registered appears to be set to 1 in _register(), but when
_unregister() is called it has the value 'None' again.
I've attached my code that's trying to implement the UserSource.
here is what my modified _register and _unregister functions look like:
def _register(self):
f=open('/tmp/zopelog', 'a', 0)
f.write('Register %s(%s)\n' % (self.id, str(self)))
f.write('Before: %s._v_registered=%s\n' % (self.id, getattr(self,
'_v_registered', 'N/A')))
for i in traceback.format_stack():
f.write(i)
if self._v_registered: return
get_transaction().register(Reporter(self))
self._v_registered = 1
f.write('After: %s._v_registered=%s\n' % (self.id, getattr(self,
'_v_registered', 'N/A')))
f.close()
def _unregister(self):
f=open('/tmp/zopelog', 'a', 0)
f.write('Unregister %s(%s)\nBefore: %s._v_registered=%s\n' \
% (self.id, str(self), self.id, getattr(self, '_v_registered', 'N/A')))
f.close()
del self._v_registered
and this is a sample log:
