The point is, *none* of my visitors use Opera, and in actual fact, almost none use anything but Explorer. My site looks like crap in Netscape 4, but I decided not to care. I first noticed the problem as visitors began pounding my script (with Explorer) . Face it, only geeks like us use Mozilla, Opera, etc. Is there a fix for the browser that my customers use? What I am trying to do is hide the actual URLs to protect my data, and at the same time record outbound clicks. I'm just looking for a solution. Thanks! Ken

PKI, SOAP with Zope?
by Teemu Yli-Elsilä 07 Nov '02

07 Nov '02

Dear All, We are considering Zope as a platform for product development in our company. There are a few important requirements the availability of which was not obvious to me. 1. PKI support for authenticating users using client-side certificates (obviously over a SSL connection). To be used with smart cards as well as certificate files as client-side authentication vessel (ie. no username/password prompts). 2. Related to the former, digital signing of content on the Zope server. 3. Further related: Encrypted storage for selected documents on the server (PGP/whatever). 4. SOAP support, acting as both server and client. Can anyone enlighten me as to the possibilities of having Zope support these? And, if a product is not available, what would it take to implement such support in Zope? We are currently only beginning to train our staff in Python/Zope, so any insight would be greatly appreciated. The products would likely utilize the CMF/Plone frameworks. Thanks in advance for any help, -- Teemu Yli-Elsilä Software Designer, Mawell Oy http://www.mawell.com/

Haven't used myself, but in the book Zope Web Application Development and Content Management is section about ExtrenalMount product - that allows you to have a no-undo section of your site on different ZODB-file. http://www.zope.org/Members/hathawsh/ExternalMount Or then you could just put cron script to clear the database undos every day? -huima

Replace files in a specific directory using pythonscript
by Heimo Laukkanen 07 Nov '02

07 Nov '02

>I know it is possible to upload a new file replacing the file for a >certain >ID because in the zope management interface this is done by editing >the >FileObject with the specified ID. >I read in the bugcollector that the method "updata_data" cannot be >used, >instead "manage_upload" should be used. ... >Can anyone provide me with a sample python script that uses (or clues >how to >use) manage_upload to upload this file to the correct ID? I don't have a sample script, but some clues to help you on. First of all, learn to check and search help from the Zope Books API section and/or the help in your Zope server. These files give you some idea atleast. And then the best source for help is the source code. If you see something done in the Zope interfaces etc. you can try to look for those sources too, for some help. But now for the real help: With the form - listing all the files in the directory, you can get a good idea from the Examples that come with Zope. There is the FileLibrary example that shows you a lot. For File object, the update function is manage_edit. So in your script you will call this function for the object you want to update. Below is how it is defined in the source ( lib/python/OFS/Image.py ): def manage_edit(self, title, content_type, precondition='', filedata=None, REQUEST=None): Hope this helps. -huima

[ANNOUNCE] The Grand Unification Theory of ZShell Scripts
by Jerome Alet 07 Nov '02

07 Nov '02

Hi, I'm pleased to announce the preview version of ZShellScripts v0.1 ZShellScripts is currently distributed under the GNU GPL, but I may change the license if sufficient interest in this product is reported... Download ZShellScripts v0.1 from : http://www.librelogiciel.com/software/ZShellScripts-0.1.tar.gz What is The Grand Unification Theory ??? The Grand Unification Theory : ------------------------------ Why would Zope only support Python Scripts ? Install ZShellScripts instead. This will allow you to add your own languages interpreters, and even define your own language syntax. Here's how : 1 - Create a Shell instance somewhere. Three types of Shell instances are currently provided : * Shell (Python) -- Can execute standard Zope Python Scripts. Code was unashamedly borrowed from Zope 2.5.1, then was re-ordered and factorized, so please report any problem. * Shell (Unix) -- Can execute Unix commands as the user Zope is run as. Variables like context, container, and so on are available as standard environment variables, but will contain the URL to the object instead of its value. This allows your shell script to talk back to Zope using wget for example ! * Shell (Zope) -- Can (*will soon*) execute Zope ZShell commands. This part is currently not working but be sure you'll get it soon !!! Shell (Python) and Shell (Unix) work as expected, as far as I have tested. 2 - Create a "Script (ZShell)" instance, and put the path to your Shell instance on its first line in the usual Unix shell scripts way : #! /path/to/myshell 3 - Put content in your "Script (ZShell)" instance, for example put Python code in it if the shell you use is an instance of "Shell (Python)", or Unix shell commands if it is an instance of "Shell (Unix)", and so on... 4 - Run your "Script (ZShell)" instance as usual, as if it was a standard Zope Python Script for example. Launching your instance, will in fact delegate the code execution to the Shell instance which path you specified on the first line of your "Script (ZShell)" instance. 5 - Enjoy ! 6 - Profit ! (ok, this one comes directly from SlashDot) 7 - Use ShellUnix.py, ShellPython.py, and ShellZope.py as examples to create your own Shell class. ZShellScripts don't need to change. Any comment, bug report or help is **very** welcome. NB : It's only a 0.1 version. Jerome Alet - alet(a)librelogiciel.com

Hi. There is the GOOD question: how to tell Oracle receive exact type? E.g. Oracle PL/SQL function to convert a string to date is like: to_date(a_string, 'YYYY.MM.DD'); Then how to create and pass Oracle Date Type via StoredProcedure, sure in Zope? -- Regards, Bogdan A Law of Computer Programming: Make it possible for programmers to write in English and you will find that programmers cannot write in English.

Redirect problem
by Ken 07 Nov '02

07 Nov '02

Hi all, The recent discussion of non ZODB-bloating counters reminded me of my unsolved redirect problem. I send my external links to a script which performs a RESPONSE.redirect. Then I can count them using Webalizer. But the problem is to redirect to off-site pdfs. This works: <dtml-var standard_html_header> <dtml-call "RESPONSE.redirect('http://dogjoy.freezope.org/redirect.html')"> <dtml-var standard_html_footer> But this doesn't: <dtml-var standard_html_header> <dtml-call "RESPONSE.redirect('http://dogjoy.freezope.org/redirect.pdf')"> <dtml-var standard_html_footer> Any clues? Thanks, Ken
