BrowserIdManager help!
by Miles 12 May '08

12 May '08

Hi, I am attempting to integrate a zope site with some other applications. I'm trying to get another application to set the _ZopeId browser/session cookie, so that users can move between the two with a single login. This requires me to reproduce the code below, so a valid broser Id is returned: (from Products.Sessions.BrowserIdManager 505:512) def getB64TStamp( b2a=binascii.b2a_base64,gmtime=time.gmtime, time=time.time, b64_trans=b64_trans, split=string.split, TimeStamp=TimeStamp.TimeStamp, translate=string.translate ): t=time() ts=split(b2a(`TimeStamp(*gmtime(t)[:5]+(t%60,))`)[:-1],'=')[0] return translate(ts, b64_trans) Unfortunately, I don't know any C, and the TimeStamp function is only available in C. I'm hoping someone can spare a few minutes to explain how this function could be coded in python so I can understand it, and produce a non-python function to return valid browser ids. I hope that makes sense! Thanks Miles

Common-Criteria certification cancelled
by Christian Theune 10 May '08

10 May '08

Hi everyone, I have to give an unfortunate update about the Common Criteria (CC) certification. The CC project began in 2003 to certify Zope 3's security architecture under the conditions of the Common Criteria framework. We started out as a community effort which turned out not to be a viable solution due to the lack of interest of volunteers and the complexity of the problem space. gocept restarted the efforts in 2006 and provided a security target document which was given to review and moving pretty good actually. There were very concrete and viable plans for 2008 to finally get the certification wrapped up by end of may. Unfortunately the project had to be cancelled due to the lack of interest of the sponsoring organisation which went through a major merger. Due to that we're stopping all activities on the certification. If interest in this should come back at some point, we'd be happy to be part of a renewed effort.

zope.sqlalchemy
by Laurence Rowe 09 May '08

09 May '08

Following discussions with Kapil, Christian and Martin I've developed zope.sqlalchemy. The aim is to provide a common base for transaction integration. It does not attempt to define any particular way to handle database configuration as there is not yet consensus on the best way to handle it. I've uploaded it to zope svn and pypi. See http://pypi.python.org/pypi/zope.sqlalchemy Currently it depends on a development version of SQLAlchemy. I hope to make a release following the 0.4.6 release of SQLAlchemy. See pypi or the readme for details, but briefly usage is something like: >>> engine = create_engine('sqlite:///') >>> Session = scoped_session(sessionmaker( ... bind=engine, transactional=True, autoflush=True, ... extension=ZopeTransactionExtension())) >>> session = Session() >>> session.save(User(name='bob')) >>> transaction.commit() Any comments appreciated. Laurence

OrderedMultiSelectWidget in Zope2: context weirdness?
by Josh Johnson (jjmojojjmojo) 09 May '08

09 May '08

I'm looking at the code for OrderedMultiSelectWidget, in zope.app.form.browser.itemswidgets (line 535). This code doesn't make sense to me: if hasattr(self.context.context, self.context.__name__): available_values = self.context.get(self.context.context) else: available_values = [] From what I can tell, this code is grabbing anything on the current content/view that's named the same as the name of the vocabulary provider. This bit me earlier with this error: Traceback (innermost last): Module ZPublisher.Publish, line 119, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 42, in call_object Module zope.formlib.form, line 770, in __call__ Module zope.formlib.form, line 764, in render Module plone.app.form._named, line 26, in __call__ Module Shared.DC.Scripts.Bindings, line 313, in __call__ Module Shared.DC.Scripts.Bindings, line 350, in _bindAndExec Module Products.PageTemplates.PageTemplateFile, line 129, in _exec Module Products.PageTemplates.PageTemplate, line 89, in pt_render Module zope.pagetemplate.pagetemplate, line 117, in pt_render Module zope.tal.talinterpreter, line 271, in __call__ Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 891, in do_useMacro Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 536, in do_optTag_tal Module zope.tal.talinterpreter, line 521, in do_optTag Module zope.tal.talinterpreter, line 516, in no_tag Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 891, in do_useMacro Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 536, in do_optTag_tal Module zope.tal.talinterpreter, line 521, in do_optTag Module zope.tal.talinterpreter, line 516, in no_tag Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 957, in do_defineSlot Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 536, in do_optTag_tal Module zope.tal.talinterpreter, line 521, in do_optTag Module zope.tal.talinterpreter, line 516, in no_tag Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 861, in do_defineMacro Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 949, in do_defineSlot Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 536, in do_optTag_tal Module zope.tal.talinterpreter, line 521, in do_optTag Module zope.tal.talinterpreter, line 516, in no_tag Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 949, in do_defineSlot Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 861, in do_defineMacro Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 861, in do_defineMacro Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 957, in do_defineSlot Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 534, in do_optTag_tal Module zope.tal.talinterpreter, line 516, in no_tag Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 824, in do_loop_tal Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 536, in do_optTag_tal Module zope.tal.talinterpreter, line 521, in do_optTag Module zope.tal.talinterpreter, line 516, in no_tag Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 745, in do_insertStructure_tal Module Products.PageTemplates.Expressions, line 221, in evaluateStructure Module zope.tales.tales, line 696, in evaluate -

Through some pdb digging, I was able to figure out that it was grabbing the view method and not the function. It makes sense looking at the code, but why would it work that way? Am I looking at this wrong, or is this a bug?

Thanks, JJ

Building on python 2.5 - any progress?
by David Pratt 08 May '08

08 May '08

Hi. I am wondering if there was any further resolution to builds with python 2.5 as discussed in the following articles: http://mail.zope.org/pipermail/zope3-users/2007-September/006909.html http://mail.zope.org/pipermail/zope3-users/2007-September/006916.html In addition to the warnings concerning initialization from incompatible pointer type, there are numerous warnings about intargfunc and intintargfunc being deprecated also. I am building on mac osx and run into these issues also. I am becoming a bit more concerned about moving to 2.5 as opposed to 2.4 for my work. Anyone building on a platform that has not posed this problem. Any compiler flags to python or recommendation for a different compiler that may help with this. Many thanks. Regards, David
