Zope runs very slowly
by Roch'e Compaan 06 May '01

06 May '01

I compiled Zope 2-3-0 from source on a Pentium II 266 MHz with 128 MB RAM on Redhat 6.2 and it runs very slowly. When I say slow I mean it takes approximately 3 minutes to start up and 5 seconds per request. I'll give a bit more background since I don't think this is a Zope problem per se. This is not a first Zope install - on our public server I frequently compile Zope from source and it flies. On this particular server almost everything was compiled from scratch (kernel, apache, python, etc) with aggresive optimization turned on. All the software installed is really running smoothly except for Zope. I then recompiled python with no optimization but still Zope was crawling. It took me quite a while to build the server thus far and it took a lot of effort securing and optimizing it but at the moment I really don't have a clue where to start looking for the problem. What is funny is that other python-built software like mailman is running up to speed but mailman is not multi-threaded or nearly as complex as Zope. It seems to me that accessing the Data.fs file is problematic, because the harddrive just seems too busy compared to other Zope installations we've made. The load on the CPU seems normal. Any pointers would really be appreciated. Roché

create ZClass instances in Python scripts
by Arkaitz Bitorika 06 May '01

06 May '01

Hi, Is it possible to create programmatically ZClass instances from Python scripts? I haven't been able to do it. I have the next thing in my Python script: folder.manage_addProduct['MyProduct'].manage_addMyZClass_py(myId) And then I have a Python Script called "manage_addMyZClass_py" in "MyProduct" that does simply this: container.MyZClass.createInObjectManager(id) All this gives me the next message: Error Type: TypeError Error Value: not enough arguments; expected 3,got 2 This happens when calling createInObjectManager(), because it expects a REQUEST object, but I don't have one! It won't accept a None REQUEST object either. Any hint? Cheers, Arkaitz.

Announce - Audio Product
by marc lindahl 06 May '01

06 May '01

Odd that noone has made a product for audio storage, analogous to Image, so I took a crack at it. So far it parses MP3 tag data. Anyone have info on RealAudio tag data? Since it's based on File, it'll actually store anything. But the cool thing is, it sucks the ID3 tag data out of the file (if there is any) and puts it into properties, so it can be indexed. You can also edit the data in the properties page, and whenever the audio is rendered, the new tag data is inserted. It should be easy to add stuff to look for WAV and AIFF header info and suck that out, since python comes with libraries to do that, but those aren't popular web formats so I haven't done it yet. It's not CatalogAware, just as Image.... I figured you'd wrap it or whatever to do that, but I'm open to suggestions. It's the first release, so obviously don't depend on it to launch rockets :) Get it here: http://www.zope.org/Members/bowerymarc/Audio

newbie question about aquisition
by Tomas Mortensen 05 May '01

05 May '01

hi, consider the folowing scenario: an index_html dtml document is located in the root folder. this document includes another dtml document, includefile, with the dtml-var tag. /index_html /includefile /myfolder/includefile /myfolder/mysubfolder/ if i access the URL http://myhost/myfolder/mysubfolder, i get the index_html file from the root folder, by aquisition. the problem is that the included dtml file _also_ comes from the root. what i want is that the includefile in myfolder will override the one in the root folder. is this posible? -Tomas

Re: [Zope] Zope as Portal Server
by dave＠kovach.com 05 May '01

Also, Another way to think of this is using ZOPE as an integration layer between many different enterprise applications via the web. Its great at Content Management (a Portal of sorts) and other intended uses - seems like its functionality could be geared around the above too. You then have total control of an enterprises web-offerings to public, employees, vendors all in one place too. Thoughts?

Don't know anything about iPlanet, but I think this would be pretty straightforward with Zope. NPS does a lot more however, it allows the administrator to customize what the user can see/select. There's a hierarchy of settings/authority/views etc that is tightly integrated with NDS (eDirectory). You could model this on LDAP. > what does your gadget for NPS interface with? or is it a generic interface > to anything? It's a daily fortune, like the Unix fortune program.

getPropertyType
by Tim Hicks 05 May '01

05 May '01

I have a zclass that has a property sheet called 'details' and I am trying to create a form for editing this that goes through the property sheet (using dtml-in) and creates the correct input box. Everything works, except the getPropertyType part, which always returns 'None'. The ZQR says that it will do this when the property doesn't exist, but the property clearly does exist as propertyIds() finds it, a getProperty() does actually return the value of the property. I just want to see what sort of property it is so that I can present the correct type of input box. Here's the code snippet. <dtml-in "propertysheets.details.propertyIds()"> <dtml-let pid="_['sequence-item']"> <tr> <th align="left"><dtml-var pid></th> <td><dtml-if "propertysheets.details.getPropertyType(pid) == 'text'"><textarea name="<dtml-var pid>"><dtml-var "propertysheets.details.getProperty(pid)"></textarea><dtml-else><input type=text name="<dtml-var pid>" value="<dtml-var "propertysheets.details.getProperty(pid)">"></dtml-if></td> <td><dtml-var "propertysheets.details.getPropertyType(pid)"></td> </tr> </dtml-let> </dtml-in> And here is a sample of what it generates. <tr> <th align="left">name</th> <td><input type=text name="name" value="Tim Hicks"></td> <td>None</td> </tr> <tr> <th align="left">email</th> <td><input type=text name="email" value="tim(a)sitefusion.co.uk"></td> <td>None</td> </tr> Any ideas? tim
