Segmentation fault when adding new objects

I'm having trouble with the adding of new objects; specifically it's adding of rfc822_address objects (contained within the ZopeGUM distribution, http://www.zope.org/Members/morphex/ZopeGUM) I haven't really got a clue what's wrong, have any of you? -- Start debugging session > /usr/local/Zope/lib/python/SearchIndex/UnTextIndex.py(244)index_object() -> old = d.has_key pdb> > /usr/local/Zope/lib/python/SearchIndex/UnTextIndex.py(245)index_object() -> last = None pdb> > /usr/local/Zope/lib/python/SearchIndex/UnTextIndex.py(253)index_object() -> src = self.getLexicon(self._lexicon).Splitter(k) pdb> > /usr/local/Zope/lib/python/SearchIndex/UnTextIndex.py(186)getLexicon() -> def getLexicon(self, vocab_id): pdb> > /usr/local/Zope/lib/python/SearchIndex/UnTextIndex.py(192)getLexicon() -> """ pdb> > /usr/local/Zope/lib/python/SearchIndex/UnTextIndex.py(193)getLexicon() -> if type(vocab_id) is not type(""): pdb> > /usr/local/Zope/lib/python/SearchIndex/UnTextIndex.py(196)getLexicon() -> vocab = getattr(self, vocab_id) pdb> > /usr/local/Zope/lib/python/SearchIndex/UnTextIndex.py(197)getLexicon() -> return vocab.lexicon pdb> --Return-- > /usr/local/Zope/lib/python/SearchIndex/UnTextIndex.py(197)getLexicon()-><Globbin... 89f3e28> -> return vocab.lexicon pdb> > /usr/local/Zope/lib/python/SearchIndex/GlobbingLexicon.py(242)Splitter() -> def Splitter(self, astring, words=None): pdb> > /usr/local/Zope/lib/python/SearchIndex/GlobbingLexicon.py(243)Splitter() -> """ wrap the splitter """ pdb> > /usr/local/Zope/lib/python/SearchIndex/GlobbingLexicon.py(248)Splitter() -> return Splitter(astring) pdb> --Return-- Segmentation fault morten@slakka:/usr/local/Zope/lib/python > -- End debugging session -Morten

Questions about implementing object models with ZPatterns
by Itai Tavor 01 Nov '00

01 Nov '00

Hi, How do I implement gen-spec classes using ZPatterns and ZClasses? For example, I want to implement Person and Customer. Writing it in Python, it would be easy to subclass Person to get Customer, and Customer would inherit Person's properties and methods. If I instead create a specialist and ZClass for each class, do I use a SkinScript to remap Person's properties into Customer? And what about the methods - Customer can't inherit Person's methods, so I have to write methods in Customer which call the same methods in Person. This seems terribly complicated... am I missing something? Another question: In Coad's examples, if a class has an 'n' order relationship to another class - say Order and OrderItems, Order would contain a list of OrderItems. Each OrderItem would contain the id of the Order it belongs to. It seems to me that it would be easier for Order to call OrderItems.getItemsForOrder(self.id), then I don't have to maintain a list in Orders, and if I add an OrderItem the Order will immediately know about it without me having to call it and tell it the OrderItem was added. Is there anything wrong with this approach? TIA, Itai -- Itai Tavor "Je sautille, donc je suis."

Re: [Zope-dev] ACL users and Packing the DB
by kdl＠Spatial.Com 31 Oct '00

Thanks, I did find the error on why Lynx was not working. Was just a brain fart on my end. I forgot to include the single quotes around the url. example : lynx -auth=username:password ' http://www.yourdomain.com/test?ids:list=acl_users&manage_delObjects:method=…' Test is just a folder that has a user folder in it. So you can use this to delete users in lower folders why keeping the admin in the root. For anyone who does not know why I needed the quotes .... in uxin the & symbol pushes the program to the background . So lynx would run but only up to right after the acl_users line. Putting in it single quotes says not to change and run as is.

I think Lynx gets > confused by the fact that the URL does not point to a .htm or .html file. I doubt it is the lack of .htm/.html. Ihave a cronjob set up via lynx that accesses a zope URL that doesn't have a .anything, and it works flawlessly. Add the --source switch to lynx, it should work then. In my case, I call a URL that creates an instance of a ZClass. I suspect the username:password _may_ be a factor, but it is likely you just need to add the --source. -- E PLURIBUS LINUX _______________________________________________ Zope-Dev maillist - Zope-Dev(a)zope.org 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 )

Re: [Zope-dev] Recursive folders from Python

What it does, however, is trying to add the new folder in the object named 'folder' (accessible from 'self'). This may well go wrong. Keep in mind, that the local name space of the function 'create' (where your variable 'folder' lives) is disjunct from the attribute namespace of 'self' (where the attribute 'folder' lives). Dieter

ZWiki 0.7.0 release candidate (was Re: Cruft on dev.zope.org)
by Simon Michael 31 Oct '00

31 Oct '00

Heyyyy 8-) ... sounds like a good time to mention the below (and Ken, your new feature priorities look very close to mine): I have uploaded a release candidate: http://zwiki.org/zwikidir/releases/ZWiki-0.7.0.tgz . Please hammer on it if you can - tomorrow is an auspicious date for release! ZWiki 0.7.0 2000-10-31 "Halloween!" * cookie-based user options, including edit form size, timezone, bookmarks and wikiwikiweb-style username (help from Phil Armstrong) * ZWiki is now zope 2.2-compatible (Garth Kidd) and -requiring, and benefits from the 2.2 security model. Executable dtml pages now run with those permissions that are common to both the page-viewing user and the wiki web's owner. Set the folder's owner to limit the permissions of executable pages. * incorporated & updated Chris Withers' product for creating wiki webs * added streamlined "hierarchal2" wiki style & other layout tweaks * wikiwikiweb-style late page creation * added simple javascript-disabling code * made paths work with virtual hosting again (Evan Simpson) * fixed unreliable ! line protection in structuredtext modes * fixed unreliable remote wiki links in classicwiki mode * more permissive remote wiki link regexps (Geoff Gardiner) * "with this" dtml kludge no longer needed * added built-in defaults for all dtml methods * simpler, more consistent urls & api * code refactoring/cleanups, other misc. bugfixes It's dark.. and the witching hour is near. Don't be afraid.. :) -Simon
