Domain and Password blank
by Juan Javier Carrera Obrero 18 Sep '01

18 Sep '01

Hello, I have created a user with the password blank, specifying a domain and a role called "guess" that I had created previously from the "security" of the root folder. Then, I have created a LocalFS, and I have assigned it the "Access content information" and "View" to the "guess" role (the anonymous user do not have permissions), because I want all the users from that domain can access to the LocalFS without having to log in. However, when I access from the browser, Zope shows the window for "Log In". When I type the username (without password), then I can access to the LocalFS. But I want to access directly without to type the username (by teory it should be thus, because I have specified the domain, the role and the password blank) Anybody knows to what happen? Thanks.

ZCatalog bug
by Steve Alexander 18 Sep '01

18 Sep '01

I'm updating a site that is currently using Python 1.5.2 and Zope 2.3.something to use Python 2.1 and Zope 2.4.from_cvs. I've had a problem: most products won't initialize. They fail on an AttributeError in SearchIndex/UnTextIndex.py related to setting up the help system. This ugly patch fixes it. There must be a better way! *** /lib/python/SearchIndex/UnTextIndex.py.original --- /lib/python/SearchIndex/UnTextIndex.py.new *************** *** 327,333 **** return 0 lexicon = self.getLexicon(self._lexicon) ! splitter=lexicon.Splitter wordScores = OIBTree() last = None --- 327,337 ---- return 0 lexicon = self.getLexicon(self._lexicon) ! ! try: ! splitter=lexicon.Splitter ! except AttributeError: ! splitter=lexicon.lexicon.Splitter wordScores = OIBTree() last = None *************** *** 343,349 **** # Convert scores to use wids: widScores=IIBucket() ! getWid=lexicon.getWordId for word, score in wordScores.items(): widScores[getWid(word)]=score --- 347,356 ---- # Convert scores to use wids: widScores=IIBucket() ! try: ! getWid=lexicon.getWordId ! except AttributeError: ! getWid=lexicon.lexicon.getWordId for word, score in wordScores.items(): widScores[getWid(word)]=score -- Steve Alexander Software Engineer Cat-Box limited

WebDav Bug?
by Phil Harris 17 Sep '01

17 Sep '01

All, I'm in the process of creating a Python based equivalent for Cadaver. I think there is a minor but very annoying bug in the Zope WebDav server. I don't think the contents of the properties are being quoted. For instance: One object in my ZODB has a title of 'Declare interfaces for MIMEtype <-> Type object registry objects.' The '<->' is what causes the problem when parsed by xml.dom.minidom. Any ideas whether I'm right, and if so what can be done. Phil phil.harris(a)zope.co.uk +1 family member.

More on WebDAV properties.
by Phil Harris 17 Sep '01

17 Sep '01

Andreas/all, hmm, now I'm confused. Looking at PropertySheets.py, it seems as if the properties are quoted, a call to xml_escape is made with the value of the property as the parameter. This call is made in dav__allprop, it seems as if it's in the proper place and all, so what is going wrong? Any other ideas? Phil

Naive API question(s)
by Holger Blasum 17 Sep '01

17 Sep '01

Dear *, naively I volunteered for a talk on zope in autumn to a (small) CS student audience. However, I must confess that do not understand the basics about the API: What is the most general and state-of-the-art way (including necessary imports from the zope python library), to non-interactively - add an Object o of type (class) t in context (directory location) c to Zope ? - call a method m of that object (that eg was found in its source code) ? - (optional) set and alter a public attribute a of that object ? - delete that Object o from context c ? Background: I naively assume that from a developers point of view, zope is nothing but a (great) storage bin for all kinds of objects (of course all the "hard stuff" has been done, with a nice user GUI, persistence, caching, transaction integrity etc). And then I felt reassured that is also nice to know that in principle everything(?) is accessible via (authenticated) XML-RPC: class XMLRPCMessageHandler(StackMessageHandler): def __init__ (self): self.stack = [] self.bat = BasicAuthTransport("guest","*****") self.server = xmlrpclib.Server("http://localhost:9673/", self.bat) self.server.manage_addDocument('foo3','Foo3','foo3s content') However, as far as I understand (OFSP/__init__.py of version 2.3.3-1, l. 121) "manage_addDocument" is a "legacy" API in the same way eg overuse of DTML is partly legacy-related, nor do I find a method for eg deleting documents in the Zope Book Appendix API doc. Also the ZSyncer source seems to give some hints but for me it is hard to differentiate ZSyncer-specific and general stuff. Again, the question is *not* about how to write Products/scripts/ZClasses but rather to demonstrate that there is an elegant and coherent approach to the API, its about http://www.zope.org//Wikis/DevSite/Projects/APIDocs/TheProblem ... (in case it boils down to RTFS pls point out which files or which products are fruitful) Many thanks in advance, -- Holger Blasum <holger(a)blasum.net> GnuPG 1024D/1CCA6604639C07F5146A

If instead write this:   test<BR>   This work and diplay correctly: test test. This problem there is only ZOPE 2.4.0, the precedent version is run OK. Can you help ME ?

exceptions on windows
by kapil thangavelu 16 Sep '01

16 Sep '01

i've always been curious why zope on windows with a bundled python seems to have problems with finding the standard lib exceptions. does anyone know why? for example from exceptions import SyntaxError class MySyntaxErr(SyntaxError): pass in a product generates an import error. (i last noted this behavior on 2.2, haven't used windows since...) thanks -kapil
