Re: Threading, dtml and performance?!

Well I've tested your script with an old backup of Zope 2.3.2 on an Win NT SP 5 machiene. There are no problems. The script runs in one window and in the other I can surf the management screen. My Solaris can't do that. On Solaris and on NT I could see your second problem. When I press cancel on the Browser the process/thread doesn't stop. Thats really a problem. I started your script twice and the machiene (NT) is nearly not usable anymore. But thats better than Solaris - there I can't start the process twice! For me I've prooven that there is something VERY WEIRD with the Solaris Zope. OK it might not be Zope but Python. As for me I need an answer / solution desperately! Any ideas anybody? My primary guess is, that Solaris doesn't relese the threads after using them. I've tried a threaded Python script on my Solaris machiene and that had no problems. But I must confess I have no clue on how Zope Threading works. Therefore my test doesn't proove anything really. By the way...it also shows how fast Zope really is because if I run "singlethreaded" and Zope can still serve a few thousand requests a day thats really not bad.

Assigning One dtml-var to Another
by Ben Ocean 02 Nov '01

02 Nov '01

Hi; I have a dtml-var called *select-blueline* It reads thus: <dtml-var expr="_.whrandom.choice(images.bluelines.objectValues(['DTML Method']))"> I need to be able to assign the value generated from this method to ANOTHER method that I can call. In other words... <dtml-var x> = <dtml-var select-blueline> Then later call <dtml-var x> How do I do this? TIA, BenO

REQUEST.items() problem
by Juan Garcia Garcia 02 Nov '01

02 Nov '01

Hi, i'm trying to show all data contained by REQUEST, but when i write the next code, the computer overloads and Zope doesn't response: <dtml-in "REQUEST.items()" sort> <dtml-var sequence-key>:<dtml-var sequence-item><BR> </dtml-in> If i use REQUEST.form.items() or REQUEST.cookies.items(), it works perfectly, but there is data in 'Other' that i need. Am i doing something wrong or is a problem of Zope? I'm using Zope 2.3.3, python 1.5.2 and Debian/woody. Thanks. Bye.

action modifier adds calling method to URL?
by Milos Prudek 02 Nov '01

02 Nov '01

I have a method "run" that is called from method "display" on /presley/elvis folder. When using simple form as follows... <form action="run"> <input type="submit" name="submit" value="Run!"> </form> ... it goes to a correct URL: /presley/elvis/run ... and URL0 is /presley/elvis/run However, I'd like to use :action modifier, as follows: <form action=""> <input type="submit" name="run:action" value="Run!"> <input type="submit" name="set:action" value="Set!> </form> This works fine, but it goes to: /presley/elvis/display/run or /presley/elvis/display/set. and URL0 is also /presley/elvis/display/run or /presley/elvis/display/set. This '/display/' disturbs logic of my program (things like PARENTS). Is this standard behaviour, or a Zope fault? If it's standard, what is the advantage of this behaviour? -- Milos Prudek

RE: "ZopeTime" not defined error?
by Dave Lehman 01 Nov '01

01 Nov '01

Alright, I figured out that if I assign a user "Manager" rights, then my custom "login_form" works. However, it does *not* work if I go to my root Portal folder security tab and assign all rights to the "Member" role. So does the "manager" role have other instrinsic rights? Obviously I can't give everyone manager rights, just to work around this issue. If I stick the "login_form" in my "custom" skin folder, where would it be trying to access "ZopeTime" from that is different than the "generic" folder? And why does it think ZopeTime is not defined? --dave

"ZopeTime" not defined error?
by Dave Lehman 01 Nov '01

01 Nov '01

I'm having a problem with several DTML methods in my CMF site. When a person is authenticated as "Member" (and not "manager") there is a problem displaying some methods. But it only seems to happen if i've created a "custom" version of that form (ie. taken the method from the "generic" folder in portal_skins and made a version of it in my "custom" folder). For example, I had made a custom version of the "logged_in" method to display an extra message to the user. When the "logged_in" method gets called right after they login, is displays a "global name 'ZopeTime' is not defined" error message. However, if I remove the custom "logged_in" method and let it use the one in the "generic" folder, it works fine. So now I have the identical "logged_in" method in both folders, but when it uses it from "generic" it's fine, and when it uses it from "custom" it's broken. Any ideas? I posted this in the CMF list several days ago and didn't get any response. Can anyone offer an idea of at least where I should start looking to resolve this? Is there some permission missing from my "member" security properties? --dave Here's the traceback: Zope Error Zope has encountered an error while publishing this resource.

Zope on CD ROM
by Laleh Baschardust 01 Nov '01

01 Nov '01

Hi, I am producing a manual on CD ROM with ZOPE, like I found in the HOW TO "Running Zope off CD ROM" from Jens, 2001/07/13. It helped me a lot. Autoran starts the browser (with a first information page) and the ZServer starts in read-Modus at the same time. Afterwards the pages can be loaded. Unfortunately now I have some problems: 1. The ZServer needs a long time (nearly 3 minutes) for the start-up 2. The dos-window opens 3. The ZServer in read-Modus writes the Logs in cmd Maybe you can help me to answer my questions: to point 1: How can I shorten the loading time at the beginning? to point 2: Can I run the ZServer in the background, like a service from WindowsNT? to point 3: How can I manipulate ZOPE so it will not write Logs in cmd? Are you interested why I decided to use ZOPE? I decided to go this way because: · The manual has a complex tree structure including often 5 levels. · I had to include a glossary database · I use the ZCatalogue to search the manual · I wanted to separate text and layout Thanks a lot for your help best wishes Laleh ----- Laleh Baschardust EAN.UCC - The Global Language of Business _____________________________________ Centrale fuer Coorganisation GmbH Maarweg 133 .

Photo product: how to recreate thumbnails with Imagemagick
by Timothy Wilson 01 Nov '01

01 Nov '01

Hi all, I'm using Ron's great Photo on my site. Until recently I was unable to use Imagemagick and had to use PIL to render the different images. I've got Imagemagick working now and the difference is dramatic! The PIL-rendered versions aren't even close to the Imagemagick-rendered ones. Now the question, can I force Zope to create new version of these thumbnails using Imagemagick without recreating all of them from scratch? -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.org | http://www.zope.com W.
