I'm running Zope and Plone on FreeBSD, both on i386 and alpha platforms. I seem to have problems no one else experiences (like PloneExFile being unable to handle attached files over 25 MB, or LDAPUserFolder causing the entire Zope instance to get stuck in a loop). Like MediaWiki, Apache, and PHP, most of the Zope and Plone developers do their development on Linux. Unless you are prepared to deal with the bugs, you probably should start with Linux, too.

REQUEST.form variables order
by Krzysztof Kubacki 24 Oct '05

24 Oct '05

Hi my friends :) I've noticed the following situation. When I send internet form onto PythonScript the variables in the REQUEST.form are in the different order that they were as fields in the internet form. I see when I send internet form by GET method that variables are placed in the right order in the QUERY STRING in the URL it means that Zope mixes them. How to change it? I would like to have variables in the same order as I put them into internet form. Regards Krzychu

Question: What Workflow tool to choose?
by Robert Boyd 24 Oct '05

24 Oct '05

I've been tasked with rapidly developing a demo for a proposed workflow application using Zope. I have plenty of CMF experience including customized workflows based on DCWorkflow, but I'm wondering what other workflows are actively supported and of production quality. In the past I've read blurbs about OpenFlow, ReFlow, and a Google search today turned up those and Metaflow and some others. However, many of them are dead-ends. Openflow's site is a 404 Not Found (in Italian) Metaflow: a 2002 article on ZopeMag sounded interesting, but no link to the software and I can't find it. Plus, old posts on this list make it sound problematic. Reflow turned into CMFOpenflow, which was a fork of Openflow? JaWE2Openflow sounded interesting, but the links are 404 Not Found. Is CMF(DC)Workflow my best option? My application would most likely *not* need other CMF tools, I might want it as a straight Zope 2 application. Also, I'm very new to Zope 3, does it include any workflow or have any available? Thanks, Rob

Linux/unix preferences question
by David H 23 Oct '05

23 Oct '05

Hi List, I want to soon move from Windox XP to Linux or Unix (intel/amd) for my Zope projects. Just wondering if users experienced with these can recommend versions (freeBSD?, SuSe?, Red Hat? etc) that plays well with Zope and those to avoid. Thanks, David

Zope crashing a RedHat installation?
by Aaron Bauman 22 Oct '05

22 Oct '05

Hi, We're running Zope 2.7.3, Plone 1.0.something relatively large Data.fs ( > 300MB ) Decent amount of anonymous traffic, But relatively low administrative use (1 - 2 users usually). Could these factors be brining the machine down? I've been getting intermittent 'corrupted data' messages for some time, but only recently been experiencing serious downtime. Is it time to seriously look at cleaning up the ZODB and upgrading? Or is my web host just trying to sell me more hardware? Any help much appreciated, - Aaron Bauman http://www.gaycenter.org

Zope Install Best Practice - Newbie Questions
by Russell Winter 22 Oct '05

22 Oct '05

Folks, First post from a real newbie, I have currently got Zope installed under a test server and would like to ensure that I get things right for our production environment. Being a complete newbie to Zope I would like to be sure I am doing things right and understood the numerous articles I have read, any assistance would be greatly appreciated. Currently, I made a user account; " zopeuser ", I installed Zope via this account and I can access the management interface without issues and managed to get a Plone installation working with mod_rewrite & mod_proxy via apache (we have a cPanel dedicated server). However, I think I may have made some fundamental administration or poor practice errors. When I compiled Zope, my source is in the same directory as my final instance, is this a security issue or at least poor practice, is there a better way to do this? If, so could someone point me in the right procedural direction to install Zope. I shall be uninstalling the instance I have, so a fresh install will be completed for the production instance. We are planning on running several Plone instances for different domain web-sites, so that each site can be managed separately by each different department. Does anybody know of any issues that we are likely to bump in to running Zope under a cPanel based server, to date I have manually added Plone accounts in the httpd.conf but will also be adding a few standard cPanel Apache based domains through the control panel as well, in time. Thanks for your thoughts, I am learning still and hopefully learning quickly, so hopefully my very basic questions will reduce over a short period of time <grin>.

fine grained, dynamic permissions based on attribute values
by Chris Crownhart 22 Oct '05

22 Oct '05

Good day, I am wondering if/how I could control the permissions on an object based on the value of an attribute. I am using CMF, and thus portal_catalog, and have built a custom content type. My type has a category field. I would like to control the view permission of the object dynamically based on the value of category. So, as an example, I have multiple users, and multiple values for the category field. I would like User A to access the object if the category ='financial', and User B access the object if the category='other'. Thanks for any ideas. Chris

FTP or WebDav creates empty files
by D Washburn 21 Oct '05

21 Oct '05

I have a desktop program that develops DTML pages for a ZOPE/PLONE website. I planned to upload them via FTP or WebDav. When they arrive they are empty. I can upload graphics via FTP and the images arrive OK. So basic transfer works. Any ideas on setting or changes needed to make the text files arrive with their content as the body of a DTML document. Thanks David
