You can run the "stop" script that is in the directory you installed zope into. In your case it will be: /home/jonano/Zope-2.1.6-src/stop -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

[Q] corrupt PDF Files?
by Veikko Wuensche 02 Jul '00

02 Jul '00

Hi, _sometimes_ ;-) I get data corruption with PDF files. After uploading a PDF file I get from the ZServer a file which is shorter than the first one. It's corrupt. The served file does not start with '%PDF-1.2^M...' for a PDF file. The original file length in this case was 482376 bytes and ZServer was sending me 458752 bytes. It should be the same length! :-) The content type ist always 'application/pdf' I've done the same steps frequently: - file upload: PDF Files - control the value of Content Type (application/pdf) Sometimes the PDF file ist corrupt - sometimes not! ;-) The same seems to appear with *.ps.gz files. We are using Zope 2.1.6 Any hint? The working PDF File (German: LinuxTag 2000-07-01 Stuttgart "Performante WWW-Umgebungen mit Zope") you can find under: http://www.lightwerk.de/zope/ Regards, Veikko -- Veikko Wünsche vw(a)lightwerk.de http://www.lightwerk.de/

Single content tree, 3 'look-n-feel's...
by Jon Franz 02 Jul '00

02 Jul '00

Hello, I'm currently preparing to build a large corporate website with Zope. the corporation in question ants a dell-ish sort of interface and content tree in which users will choose on the opening pages what Sort of user they are (home-user, small business, or corporate) - after choosing the type of user they are, the look-n-feel of the site will be geared towards their specific type, but, the content will be shared across all of the different styles. that is to say, I might have a products dtml document, but it will need to look different for each type of user. I know this can be done easily with some simple session variables and some logic in my standard_html_header and footer, but I was wondering if there was an easier (to manage - different people will be in charge of each look-in-feel) way...? I saw an announcement on "transparent" folders - would that be of any use in this situation?

When does Zope become single-threaded?
by Hung Jung Lu 02 Jul '00

02 Jul '00

Hi, I seem to remember that in the old days, if one uses Zope with PCGI, it would only run single-threaded. Is the correct? Or is Zope now always multi-threaded? (I know one can control the number of threads via the -t option in the start script.) regards, Hung Jung ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

how to invalidate an object in the cache?
by Marco Mariani 02 Jul '00

02 Jul '00

I am working with photo rotating/resizing, via PIL on external method. All the images are kept on LocalFS. There is a thumbnail bonanza page, when I select a thumbnail a form is shown, and I can adjust rotation/contrast/brightness. Upon submit, the new image+thumbnail is calculated and written to the filesystem. Then the method calls RESPONSE.redirect to show the index page again. When I go back to the index thumbnail page, the image I've just rotated is displayed with the right size (which means that Zope gets it right), but not rotated (which means that Netscape reads the old image from the cache). I mean, if it was 320x200 and is now 200x320, the browser displays the old 320x200 image stretched to 200x320. I'm not digging into contrast and brightness, but the same happens. Is there a way to force the browser to discard the cache for that image? If I go "right-button, view image, shift+reload" the new image is displayed. Any idea? I'm not very knowledgeable on this matter, I don't design pages for a living. Might javascript help? Thank you. -- "This company has performed an illegal operation and will be shut down.

What is default SU password in Zope 2.2b3?
by Alexander Chelnokov 02 Jul '00

02 Jul '00

Hello All, A friend of mine has just installed Zope 2.2b3 by, as he told, simply run install script in RedHat 5.?. He reports that at least his_site:8080 shows normal start-up screen but no password was displayed during installation so he can't proceed to managemet screen. Zpasswd.py utility seems not to work due to lack of some library (?). Should he reinstall Zope or there is a default password? Best regards, Alexander N.

PCGI Error: (102) failure during connect to ZServer
by ChristianThayer＠mailandnews.com 02 Jul '00

02 Jul '00

This is with Zope-2.2.0b3-src.tgz The pcgi wrapper reports ...is unable to connect to the ZServer background process via Unix socket .../var/pcgi.soc I am trying to install this on a remote host, this error came up locally too, though. I followed glndspud's howto on 3rdparty host setup. With a 2.1.6 release I was able to get zope running. However, with this setup I was not able to login through manage, the authorization did not work. So my reasoning, an upgrade should make this error vanish. Not so, until now. ;-( Christian

Fun with Trees
by Charlie Wilkinson 02 Jul '00

02 Jul '00

(I always wanted to be a lumberjack! :) After RTFMing and flailing at DTML all night, I'm about stumped. No pun intended. I'm trying to use dtml-tree to create a selective menu of objects based on whether or not the object has an "add_to_menu" property. I've pretty much figured out that I need a wrapper around objectValues that will filter out the objects that don't have the "add_to_menu" property. This wrapper would be called with dtml-tree's "branches" attribute. I'm trying to do this wrapper in a DTML method and I've gotten all the way to where I have to return a list of "actual objects", so says the DTML Quick Reference. Is there someone who could 'splain to me how to build a list of objects in DTMLese? Here's what I have so far (obviously not working): <dtml-call "REQUEST.set('ret', '')"> <dtml-in "objectValues()" sort=id> <dtml-if "_.has_key('add_to_menu')"> <dtml-call "REQUEST.set('ret', ret + ' ' + _['sequence-item'])"> </dtml-if> </dtml-in> <dtml-return "_.string.split(ret)"> Right off the bat, Zope is giving me attribute errors about REQUEST, but I'm not sure how else to do a set(), other than with REQUEST or RESPONSE in front of it. When I ran it stand-alone, I was *not* getting attribute errors and *was* getting output that looked remotely like the guts of the desired objects. Spare clues anyone?

Zope dumps core while querying on id
by Luke Tymowski 02 Jul '00

02 Jul '00

Hello, Actually I suppose it's Python that's dumping core. The following query causes a core dump: <dtml-with history> <dtml-with 2000> <dtml-in "objectValues(['DTML Document'])" size=3 sort=id reverse> <dtml-var sequence-item><br> </dtml-in> </dtml-with> </dtml-with> The following query works as expected: <dtml-with history> <dtml-with 2000> <dtml-in "objectValues(['DTML Document'])" size=3 sort=title reverse> <dtml-var sequence-item><br> </dtml-in> </dtml-with> </dtml-with> Any idea why? I'm using 2.1.6. The other day I posted a question asking why my bobobase_modification_time was off by 1 day. I got no answer. But upgrading from 2.1.4 to 2.1.6 seems to have fixed that issue. The core dump happened in 2.1.4, so I upgraded to 2.1.6, but the core dump issue remains. thanks, Luke
