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

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

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

which Linux ?
by Jason Cunliffe 14 Mar '00

14 Mar '00

Hello We are about to configure a brand new machine for a Zopesite. Q: Which Linux to install.. We are tilting to RedHat.. Welcome any comparisons, recommendations, or guides about this.. RedHat SUSE Caldera Debian Corel ??.. -Is there a recent table or article which lists the pros and cons which relate to Linux family & Zope? -What are the statstics among Zope users ? -Does Digital Creations know? -Does it matter and if so : why / whynot? I do _not_ want to start Linux vs. Linux thread.. but it seems to me that a useful public page should be on zope.org with links to the How-Tos per Linux for gotchas etc.. If you prefer reply to me off-list. Thanks in advance any help. - Jason Cunliffe __________________________________________________________________________ Jason CUNLIFFE = NOMADICS.(Interactive Art and Technology).Design Director

RE: [Zope] More Z SQL head bashing...
by Daniel.Weber＠SEMATECH.Org 14 Mar '00

I had a similar problem I just puzzled through, though I'm pretty new and don't know the right ways yet :-) What I did was create another DSQl query (sql_newID) that queried for the new ID (select max(ID+1) as newID from table) and another sql_exist( select count *....) then I used this result, but it had to be within a <dtml-in > tag... <dtml-in sql_exist> <dtml-if "exist > 0"> <dtml-in sql_newID> insert into table (ID, name) values (<dtml-var newID>, <dtml-sqlvar name...> </dtml-in> </dtml-if> </dtml-in> This worked because I knew the sql_newID and sql_exist will only return a single value, so the loop only iterates once. I've never seen the <dtml-var sqldelimiter>, though, so I don't know what it does.... Maybe this will help..... > > Well, further to my earlier SQL post, here's the code I'm > trying to encapsulate, but it doesn't work > ;-) > The problem is one of getting a unique, integer, id from > MySQL to use as a primary key for an > INSERT.

FYI: Potentially speaking at BALUG next Tuesday
by Paul Everitt 14 Mar '00

14 Mar '00

Howdy sports fans. If the San Francisco traffic doesn't double cross me, I'll be speaking at the Bay Area Linux User's Group meeting next Tue, Mar 21. The complication arises because I'm speaking down in San Jose at SDWest from 5PM-6PM, then have to hurry back to hopefully make the BALUG meeting. Unfortunately I don't have a URL handy for time, location, etc., but I'll try and post it when I'm back in the office. The subject of the talk is, well, Zope, plus a Big Announcement. --Paul
