Re: [Zope] Zope in chroot enviroment
by Andrew Diller 14 Mar '00

Well, I can't give it python, that would defeat the purpose of the chrooted webspace. It seems to me that Zope maynot lend itself to being frozen. Has anyone out there frozen Zope and managed it to continue to work? >>>>>>>>>>>>>>>>>> Original Message <<<<<<<<<<<<<<<<<< On 3/11/00, 4:35:44 AM, Bill Anderson <bill(a)libc.org> wrote regarding Re: [Zope] Zope in chroot enviroment: > Andrew Diller wrote: > > > > Is anyone running this? > > > > Can it be done?

RE: [Zope] getting object from path
by Jason Spisak 14 Mar '00

14 Mar '00

R. David, I think you want <dtml-in "Catalog(mystuff=mystuff)"> <dtml-with "resolve_url(getpath(data_record_id_),REQUEST)"> <dtml-call "propertysheets.MyProperties.manage_changeProperties( blah=foo blahblah=bar )"> </dtml-with> </dtml-in> This will change the properties to whatever you want for the instances found in the above Catalog search (mystuff=mystuff). All my best, Jason Spisak 444(a)hiretechs.com

Getting the path of an Object
by Daniel G. Rusch 14 Mar '00

14 Mar '00

Hey all, hope this one is relatively easy... Background: 1. I have a zope site with folders, subfolders (possible several levels of subfolders) and objects in them. 2. I built a simple interface to allow a user (with the correct permissions) to see the tree. 3. In the UI, each item (folder, subfolder, object etc) has a check box. Kinda like the Zope UI The question: A user checks an object (folder, subfolder, object etc), how do I get the path to the object that is checked. i.e. FolderA SubFolderB SubFolderC index_html Suppose the user checked index_html in subFolderC. How do I get the path (which would be FolderA/SubFolderB/SubFolderC/index_html) The test code I am using looks like this (it's in a DTML Method): <dtml-var standard_html_header> <FORM ACTION="WhichFilesToExport" METHOD="POST"> <dtml-tree branches=objectValues> <INPUT TYPE="CHECKBOX" NAME="ids:list" VALUE="<dtml-var PATH_INFO>" > <IMG SRC="<dtml-var SCRIPT_NAME>/<dtml-var icon>"> <dtml-var id> </dtml-tree> <INPUT TYPE="SUBMIT" NAME="submit" VALUE="Submit" > <dtml-var standard_html_footer> Using PATH_INFO obviously wont work since it returns the PATH_INFO of this method and not the PATH_INFO of the checked item. Any thoughts???????????? Thanks, DR

What if you can use Zope on development server only?
by Anthony Thompson 14 Mar '00

14 Mar '00

Has anyone used Zope in a scenario where you don't have control of the production server? In other words, I'm in a non-profit organization that rents space from a web host. That web host doesn't have Zope installed and has no plans to install it. I *might* be able to put Zope on my own personal Linux server, which would really make that machine like a development server. Does anyone have any experience utilizing Zope in a scenario where the development and production servers are separate and the production server doesn't have Zope on it? I'd like to use Zope because our web site has reached the point where I really can't manage it myself (Ok, it reached that point over a year ago, but I'm finally frustrated enough to do something about it :). I'd really like to be able to give other people in my organization, especially many who aren't ultra web savvy tech-heads, the ability to author content so I'm no longer a bottleneck to the site expanding regularly. Zope looks like the best open source option to do this with. I also considered Cocoon (http://xml.apache.org/cocoon/) but I know and love Python and Zope looks like it's both more mature and more well-established for this type of application. I also want to add that I *am* considering changing our web hosting provider, but due to other organizational changes in the non-profit it will have to wait at least six months (it's lower on my priority list than finding a replacement for our office manager, for example :). I guess I'm just curious if there's a way to use Zope in my current scenario, without having to change to a web hosting company that already has Zope installed. thanks for any help anyone can provide, Anthony ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Re: [Zope] EAGAIN errors crashing ZServer Aiieeee!!!!
by Jon Prettyman 14 Mar '00

14 Mar '00

Well, after more poking around and experimenting, I'm able to make an strace look like what my crashing server does by following these steps... start Zope (z2.py) wait till everybody starts attach an strace to child z2 wait till strace output shows I'm in select send child z2 a SEGV strace output matches what I see in production event.log matches what I see in production Now that I've figured this out, I managed to get ulimit set up so that I will get a core file the next time this happens. Let's hang on till I see the core. I'm also going to play with getting gdb to work nicely. I'm not sure why this is failing yet. -Jon Michel Pelletier <michel(a)digicool.com> writes: > > But fs/select.c(sys_select) (in the linux kernel) DOES return > ERESTARTNOHAND of do_select returns a negative value.

CD_ROM Applications
by jwpgh＠alink.com 14 Mar '00

14 Mar '00

Applications .... I noticed some comments about ZOPE, I am not an expert PC user, but I am interested in placing MS applications on a CD and distributing it to customers. I want this to work on as many windows applications as possible. Of course there are PowerPoint viewers I have use them satisfactorily. I have installed a project where MS Access applications run on my web site, conceptually I want to make a CD that will look and act just like the web site. I have made sever Access query applications, ASP , that I would like to package on a CD_ROM for customer distribution. I just can't seem to get started with running database applications, stand alone, on a CD without major PC installations. Can you give any hints on how to get started, Thank, Jim

Debugging a Zope Server
by Oliver Andrich 14 Mar '00

14 Mar '00

Hi, we started a new service for our online newspaper, that is served by a Zope server. (http://rz-anzeigen.de) We currently experience the problem, that the machine serves really well and also during the high traffic times. But sometime in the early morning the Zope process crashes. Now I like to know if it is possible to get some more specific out from the Zope server when it crashes. Can I activate some kind of logging to monitor this, or something else that helps me to deal with this? Or is my only option to start the Server form the shell and see what traceback I get? Bye, Oliver
