changing security settings from python
by Mario Bianchi 08 Jan '03

08 Jan '03

Hello list, I wonder if it is possible to change the security settings (the mapping of permissions to roles) on some object DYNAMICALLY, i.e. from python code instead of from the management interface. I need this feature to dynamically reflect the possible changes in the access rights of some files pointed by ExternalFile instances. Thanks, Mario. _________________________________________________________________ STOP MORE SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=features/junkmail

Zope - Document Management Integration
by Sameer Maggon 08 Jan '03

08 Jan '03

Hi all, We have our own proprietary Document Management Product. Lot of our clients have their valuable data (images, web-pages, other documents) in our repository (powered by our DM product). Now is there a way we can incorporate CMS facilities using Zope where the users can make web-sites using the content from our DMS. If anybody has some idea, please discuss it. I can mail other relavant details. Sameer Maggon

Zope Publishing
by Sameer Maggon 08 Jan '03

Hi, In some CMS we have different environment for Development (Authoring), Staging and Production. The CMS Database that resides in the Development setup is usually more bulky than the database in the production and staging site. Can any body tell me how Zope fits into this situation, is there any component that takes care of this? My major concern is that, it might be that my repository contains huge number of images but actually the site uses only some of them. So when actually deploying a site, the system should resolve those images and put the required files. Thanks Sameer Maggon

Python method wrapping around DTML method
by Bjorn Stabell 03 Jan '03

03 Jan '03

Hi, This has been buggering me for ages, and I've spent too many hours trying to figure it out already, so I'm resorting to the list for help. :) I have two functions, PlainFunc and DTMLFunc, where PlainFunc is Python method in a file system product, and DTMLFunc is a DTML Method in the ZODB. What I want to do is this: ZPublisher calls PlainFunc (publishes it) PlainFunc calls DTMLFunc in such a way that DTMLFunc gets everything it needs, e.g., namespace, but PlainFunc can do funky things to this namespace before-hand (like insert a few variables into it). In other words, I want a Python method to wrap around a DTML method. I've encountered many problems caused by the awkward calling conventions for DTML methods and the automagic switching between different calling conventions by the ZPublisher (isDocTemp; can I set that for a normal Python method?). Right now, I'm struggeling because I cannot get the namespace to be passed to PlainFunc, therefore PlainFunc cannot pass the namespace on to DTMLFunc. Any clues?

Strange Problem with a Product using SWIG Python Proxy Classes
by Sean Gillies 03 Jan '03

03 Jan '03

Greetings, My question concerns the use of SWIG Python proxy classes in a Zope Product. In the ZDG and elsewhere, I have seen the statement that if an object is pickleable, it can be used as a persistent object in a Zope Product. In my experience, my SWIG Python proxy classes are pickleable, can be stored in a ZODB, the Product that uses them can be installed in Zope, instances of the Product classes can be added and work, but on a restart of Zope, the instances of my Product classes are broken and will cause Zope to segfault on any attempt to access the proxy class. I am using Python 2.1.3 with threads and the thread stack size patch built on OS X 10.2 and Zope 2.6.0. I've had no other problems with Python or Zope on this machine until I began developing this new Product. I am developing a Zope Product that will use a Python interface to a C language GIS library. The Python module is created with SWIG (1.3.17) and consists of proxy classes that dispatch methods and member variable access to the underlying C objects. For those who are unfamiliar with SWIG, here's a link to a doc that describes the proxy classes: http://www.swig.org/Doc1.3/Python.html#n28 Basically, I have a C structure with an attribute named 'name', a C library named '_mapscript' and have a proxy class like class mapObj(_object): __swig_setmethods__ = {} __setattr__ = lambda self, name, value: _swig_setattr(self, mapObj, name, value) __swig_getmethods__ = {} __getattr__ = lambda self, name: _swig_getattr(self, mapObj, name) __swig_setmethods__["name"] = _mapscript.mapObj_name_set __swig_getmethods__["name"] = _mapscript.mapObj_name_get if _newclass: name = property(_mapscript.mapObj_name_get, _mapscript.mapObj_name_set) def __init__(self,*args): self.this = apply(_mapscript.new_mapObj,args) self.thisown = 1 def __del__(self, destroy= _mapscript.delete_mapObj): try: if self.thisown: destroy(self) except: pass As I understand, the 'if _newclass ...' code should be passed by Python 2.1. I have verified that instances of this class can be pickled using dump/load from pickle and cPickle. I have also been able to successfully save and load instances of the mapObj proxy class using ZODB from the Python interpreter (outside of Zope). Instances loaded from a non-Zope ZODB FileStorage work as designed. In my Product, I use this SWIG Python proxy class as a member of a Python class (here's a fragment): def ZMap(...): def __init__(self): self._map = mapObj() def __del__(self): del self._map def getName(): return self._map.name I created methods to add the Product and they work. Once the Product is installed, I can add new instances and they work just as I've designed. For example, when an instance named 'map1' is added to a folder under the root named 'Maps' I can access the url /Maps/map1?getName and I get exactly what I expect. However, when I restart Zope, any attempt to access that url causes a segfault and a restart of Zope. I have had the same experience with testing my Zope FileStorage (Data.fs) from the Python interpreter. Newly created instances of my ZMap class work fine. Saved instances loaded from Data.fs are broken and cause a segfault when I try to access any member of _map. I'm very puzzled and would greatly appreciate answers, annecdotes or ideas from anyone who has experience in this area. thanks! Sean # Sean Gillies # sgillies(a)frii.com

Zope 2.6.1 beta 2 deferred until January
by Matthew T. Kromer 24 Dec '02

24 Dec '02

With the holiday schedule and people being on vacation, we have decided to defer issuing a Zope 2.6.1 beta 2 release until after the first of January, to avoid the necessity of creating a beta 3 release (because of any potential bugs in beta 2 not found due to people being away.) Have a Merry Christmas and a Happy New Year.

What prompted this? What does it fix? I don't see that quotes need escaping here. Also, there should be a unit test for it. (And if it's a fix it should be in HEAD too.)

FYI: added Web Services Zope 3 sub-project
by Brian Lloyd 23 Dec '02

23 Dec '02

(Copying zope-dev because I'm not sure all of the people who started on this discussion are on zope3-dev yet. Lets use zope3-dev moving forward) Hi all - There has been a bit of discussion recently regarding plans for web services in Zope 3, with a number of people expressing interest in moving this forward (and possibly scheduling some WS sprints to kick-start the process). For those who've been paying attention to those threads, I've set up a Zope 3 sub-project at: http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/WebServices ...with a start at some organization and artifacts (largely cribbed from the old Z2 WS project). Please take a look and feel free to jump in an refine, comment or refactor. One of the first things we need to do is find someone (or a group of someones) to spearhead the effort and "own" the project area. Any volunteers? :^) Brian Lloyd brian(a)zope.com V.P.

RE: RE: Re: [Zope-dev] Where can I find the Zope XML DTD ?

They solve the programmer issues. These tools haven't really recognized the translator role and how they work. They are not Zopatists and not any kind of Zope editor, they work in other companies and use their own tools and XML standards. If we want Zope to be a real Multilingual Content Management Tool then it would be a good choice to adabt Zope to the standards used in these translations tools. >I have not looked into Localizer or ZBabel in detail. > >However, as I understand them, they work with message catalogs (maintained, >e.g. in a database). >If this is true, you simply export these catalogs in a format your >translators like, let them be translated and reimport. > If all text was kept in a message catalog then yes. This would be the way to go. I think ZBabel keeps all translated text in a central database while Localizer keeps the text tight together with the object instances ... there are pro and contra for both solutions ... I will probably implement some product that export/import Localizer objects to XLIFF. That would be the best solution I think. Let's see if this christmas holiday we'll help us come up with other ideas ;-) Thanks for your help, Antonio > >Dieter > > _____________________________________________________________ Här börjar internet!
