The APIs are exposed in all the ways JAVA, DLL and can be exposed in any way.

What platform are you using? windows, *nix? \Oliver

Well.. we have our own proprietary repository and have XML APIs exposed that can be used to interact with the system.

By repository - do you mean that you have made your own database? \Oliver

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

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
