about zope and mouse event handling
by Allen Huang 10 Feb '06

10 Feb '06

I want to make a web page that could handle mouse events. My primary goal is to do some image processing like zooming and panning on an image displayed and redisplay it on the same page. But I don't really know how to approach this and at the same time interacting with Zope to retrieve relevent information from the database. I was reading GUI with python coding but I don't know how to connect it with zope database. Is this method possible? Is there any other methods I could look into? --------------------------------- Relax. Yahoo! Mail virus scanning helps detect nasty viruses!

Hi all, My name is André. I'm working on a research prototype that tries to cluster web pages by tracking the interests of users (by recording the users' searches and accepted links) and relates that with an adaptive crawling mechanism. The address is http://andrers52.dyndns.org:8080/z9 The development is all being done in zope. I would like to invite everyone. Any comment is appreciated! Cheers! André

This is from a class that is based on ParsedXML.ParsedXML, caveat: It's code from an old project that isn't maintained and maybe it was done suboptimal anyway :-) def get_Status(self): doc = self.documentElement status = doc.getElementsByTagName('Status')[0].getAttribute('Number') return { 'Status':str(status), 'Schema':'ImageID' } another one: def get_photo_count(self): return self.documentElement.getElementsByTagName('Photo').length the manage_addXY method of that object has something like this inside: try: b = NetSelection(id, file, useNamespaces, contentType) except expat.error, e: ... do things here and the class has no explicit __init__ method, so likely we got that from the ParsedXML.ParsedXML base class. also there seems to be stuff that adds/changes things in some methods: if not new_node: new_node = this_Photo.appendChild(doc.createElement(Network_Description)) or: def _set_description_on_node ( self, node, Description_Dictionary ): ''' "sets" the contents of a Dictionary into an XML node ''' for fred in Description_Dictionary.keys(): node.setAttribute( fred, Description_Dictionary[ fred ] ) Is that the kind of thing you were looking for?

zope file system folder(severe problem)
by Giorgos Dimitriou 10 Feb '06

10 Feb '06

Hello Zope, I am new to zope and I'm exploring different products an functions. A couple of days ago I tried to install a zope product called zope file system folder, on a zope 2.8.4 linux(Red Hat core 4) installation. What this attemt caused was a severe damage of the linux partition. The exact boot error message is this: JDB:Failed to read block at offset 7609 EXT3-fs:error loading journal I tried rescue mode but it whouldn't even let me mount the partition. Anyway I managed to save my work files using a windows utility (Fortunatly I have windows booting too.) and lost a day's work reinstalling and reconfiguring my linux. Could somebody please tell me why did that happen? I need the functionality of file sytem folder but I sure wouldn't risk installing it again!

Thanks for the help. I got some good Apache advice on the Plone list vis a vis <location> What I'd like to do is have Apache and Zope (roles, workflow) for extra security over SSL. I'll re-visit the authentication issue with the help I've received. On 2/9/06, michael nt milne <michael.milne(a)gmail.com> wrote: > > Thanks for the help.

Session Variables Redux
by Dennis Allison 09 Feb '06

09 Feb '06

Zope 2.9.0 Python 2.4.2 There appears to still be a problem with session variables that does not appear to be the result of interactions with conflicts nor the result of unexpected restarts. It does not appear to be load related. The problem we see is a sudden disappearance of all, one, or a small number of session variables. In a session varaiable stateful system this is an embarassment. The behavior is a bit like a variable which is not identified as persistent, but all read and write accesses go through a getSessionVariable/setSessionVariable interface: ## Script (Python) "getSessionVariable" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters=varname ##title= ## request=container.REQUEST session=request['SESSION'] return session[varname] ## Script (Python) "setSessionVariable" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters=var, val ##title= ## request = container.REQUEST session=request['SESSION'] # write only if necessary if not session.has_key(var) or session[var]!=val: session[var]=val Our session lifetimes are long (hours, days) and conflicts are fairly frequent. Hand checking of the logs does not show any obvious correlation between session variable loss and conflict. Moreover, all conflicts are "resolved". Does anyone else see this sort of problem? Any suggestions as to how to isolate the problem?
