RE: [Zope] Zope/Python product/wrapper for XQuery??
by sean.upton＠uniontrib.com 23 Aug '02

Jython is Python for the JVM. JPE is a fairly seamless bridge between CPython (what Zope runs in) and Java, allowing you to instantiate instances of Java Classes in CPython, use them, and (if I understand correctly) vice versa. Jython cannot do this. If you want Zope-Java integration, you want to use JPE. If you want to use an Xquery component from Java and instantiate a component (from Java classes) to do this, and use you Python data structures, you likely want to use JPE.

I thought for Java stuff Jython was the way to go... but I dont know if it is stable enough for use on a production site. What are the perl options that I have given that PyPerl and Zope-perl are still in beta stages..??

Does Zope's FTP server provide "resume after disconnect"?
by vsbabu＠vsbabu.org 23 Aug '02

23 Aug '02

Hello, I'm trying to setup a CMF site. This will hold large (~50MB) binary files too. I'm thinking of using CMFOptions for ExternalFile support so that this won't fill up ZODB. Question: People might want to download files via FTP. Does Zope's inbuilt FTP server provide functionality where broken downloads can be resumed? Thanks in advance Satheesh Babu http://vsbabu.org

Hello zope users, I need your help with following situation. I have started to use FormulatorLayout Product, which in turn uses Formulator Product, to layout and render my forms. But the speed of rendering form with about 40 elements takes 10-20 seconds. Can you explain me how I can improve the speed of rendering these forms? Your help is very, very appreciated. -- Best regards, alienoid mailto:alienoid@is.lg.ua

IE rejects cookies
by Jacob Behm 23 Aug '02

23 Aug '02

Let's try this again. I'm building an intranet for my company that has <iframe> links to other outside systems. These outside sites have there own cookie based session tracking. For some reason, Internet Explorer rejects the cookies unless I go to Tools -> Internet Options -> Privacy -> Advanced and check "Override automatic settings" and then check "Always allow session cookies". Therefore, I can't log into these outside systems. All other browsers work fine. IE works fine is I server the page through Apache or IIS. There's something about Zope that is making the cookies unpalatable to IE. Does anyone know what happens when a site generates a cookie from a frame on a Zope site? If anyone has any insight on the matter, please share it with me. Thanks, Jacob Behm

[Search] Documentation for "__guarded_*__"
by Dieter Maurer 23 Aug '02

23 Aug '02

I am searching documentation for "__guarded_getattr__", "__guarded_setattr__" and friends. The name suggests they should guard. Thus a definition __guarded_getattr__= __getattr__ is probably not very wise. Is the following definition correct when I want the dynamic attributes (defined by "__getattr__") to be protected in the same way normal attributes are: def __guarded_getattr__(self,attr): r= getattr(self,attr) if getSecurityManager().validate(accessed=self, name=attr, value=r) return r raise Unauthorized, attr Dieter

context syntax for subdir
by Tom Germaine 23 Aug '02

23 Aug '02

Hello All: I wish to upload a DTML Document to a subfolder of folderA using a form and python script which reside in the parent folder of folderA and don't understand context well enough to designate subfolder properly. The Document goes into subfolder based on it's filename and script looks something like: .... if filename[0:4]=='abc': client=context.folderA(subfolderabc) #fails at this line elif ... ... if hasattr(client,filename): #test for existence, overwrite client.manage_delObjects([filename]) client.manage_addDTMLDocument(id=filename,file=myfile,title= mytitle) else: client.manage_addDTMLDocument(id=filename,file=myfile,title= mytite) How do I stipulate subfolderabc?

RE: [Zope] dynamically generated image buttons
by sean.upton＠uniontrib.com 23 Aug '02

23 Aug '02

This functionality is really depending on the typography support on your server. I believe that ImageMagick's convert program can be set up to use Freetype and TTF fonts. This may be able to suit your needs, but you would need to code an external method to utilize ImageMagick to create the buttons for you (well, to call 'convert' at the command-line with arguments for the text and font you want to use); you would likely want to cache buttons, since auto-generated images can be expensive. Even with this, you would need to create a mechanism for making these images accessible to the templates you are using (and thus the users browsing the pages). That said, there may be ways to do this without rolling it out all on your own, but I've never tried anything like this: http://www.zope.org/Members/TheJester/ZButtons On the low-end, if your requirements are simple, and your browser clients can support it, you may seriously want to consider use of CSS and DHTML for making your buttons, since it could be done on the client without all this heavy lifting. Alternately, on the high-end, you may want to consider a product like Macromedia Generator or Adobe Altercast to do this for you on a separate server.

I mean that you have two source images (for onmouseover and onmouseout) and that "thing" will "burn" text to that images from some variable (eg., Title). I have migrate from M$ Frontpage where that feature is incorporated and in Zope is missing to me. Many thanks, J.

Vhosting
by Adam Getchell 23 Aug '02

23 Aug '02

Hello all, I've read and re-read http://www.zope.org/Members/4am/SiteAccess2/vhosting a number of times. I have a webserver that needs to host a bunch of different sites, site1.ucdavis.edu, site2.ucdavis.edu, etc. I planned to use name based redirection, so I have c-names to the IP address of the server, i.e. site1.ucdavis.edu --> IP, site2.ucdavis.edu --> IP, etc. I installed on OpenBSD, so Zope runs as an instance in /home/zoperoot under port 8080, and Squid sits in front of it and redirects from 80 to port 8080. This part is working fine. Under my main zope site, I created two folders, site1 and site2. I then created, in each folder, an empty SiteRoot. That is, Title, Base, and Path are all blank. At least, that's how I interpreted the directions above. I then created a DTML method called host_redirector, with the following content: Extract the part of HTTP_HOST we care about, and declare our rewrite dictionary. <dtml-let hostname="_.string.upper(_.string.split(HTTP_HOST, '.')[0])" sitemap="{'SITE1': 'site1', 'SITE2': 'site2'}"> Do we have a match? <dtml-if expr="sitemap.has_key(hostname)"> Set the logical root: <dtml-call "REQUEST.set('SiteRootPATH', '/')"> Add physical root: <dtml-call "REQUEST['TraversalRequestNameStack'].append(sitemap[hostname])"> </dtml-if> </dtml-let> Since I only care about the first part of the name, I rewrote the script from the example. It may be incorrect! I tried the equivalent at a python interpreter, but I may certainly have goofed up. In the root folder, I Set an Access rule to host_redirector. I changed the index pages in each of Site1 and Site2 to differentiate them. However, going to site1.ucdavis.edu gives the top level index_html, while going to site1.ucdavis.edu/site1 gives index_html in the Site1 folder, so clearly I did something wrong.
