Problem of performance
by Tom Deprez 30 Jan '01

30 Jan '01

Hi, It's strange, I thought I was rid of it, but it seems to pop-up now and then. I'm talking of a slow performance of Zope2.2.x Here is the problem: When I'm working in Zope, the following happens sometimes : eg. I copy an object and then try to paste it. The pasting can take minutes, or the interface just keeps trying to load the page. Now, when I stop the loading of the page (when it seems to be hanging) and reload the page, I see the copied object. So, it looks like Zope has problems to display the page. I've Zope installed on Mandrake and the problem occures on Netscape (Linux) as IE5.0 windows. Somebody an idea what may be the cause of this? Did something changed in the code related to this? Thanks in advance, Tom.

[Zope v.2.3.0 final] In the editPermission form what should be the 'name' input field has an incorrectly set HTML attribute (name="title"), it reads: <input type="text" name="title"size="40" value="<dtml-var name html_quote>" /> but, it should be: <input type="text" name="name"size="40" value="<dtml-var name html_quote>" /> -- Roberto Lupi

Re: How to make a zclass as default Xron methods?
by Loren Stafford 30 Jan '01

30 Jan '01

Best to address questions to the Zope mailing list. You'll get more prompt answers coupled with the collective experience of hundreds of users. I'm not sure exactly what you are asking, but I'll try to clarify, anyway... self.executeAt is the property that holds the next scheduled execution time. This property is set by manage_addXronDTMLMethod to hold the first scheduled execution time, and changed periodically by 'reschedule'. Could change addXronDTMLMethod.dtml to expose only executeAt but not periodDays or you could do the same by changing manage_addXronDTMLMethod (which is invoked by addXronDTMLMethod.dtml). -- Hope that helps -- Loren ----- Original Message ----- From: "Dirksen Lau" <dirksen.lau(a)polyu.edu.hk> To: "Loren Stafford" <lstaffor(a)dynalogic.com> Sent: Monday, January 01, 2001 7:51 PM Subject: How to make a zclass as default Xron methods? > Hi Loren, > > I want to subclass Xron method, and provide default action and reschedule > interval, leaving the initial time for customization.

I don't have much experience with this either. You should direct your question to the Zope mailing list where others can share their expertise with you (not to mention replying promptly). -- Loren ----- Original Message ----- From: "R.

Security hole in CookieCrumbler
by Shane Hathaway 30 Jan '01

30 Jan '01

Hi folks, It turns out that the released versions of the CookieCrumbler product have a terrible security hole. I recommend you uninstall it immediately. I'm not going to be able to deal with the problem fully today, but if you're interested in getting a solution right away you can grab today's PTK from CVS which contains a version of CookieCrumbler without the hole. Thanks to Phil Harris for finding the problem. Shane

Hi all! I am trying to port some web-pages from php to Zope. I am looking for the Zope equivalent of the php function Header(), which allows me to set a HTTP header: for example Header("Location: new_page.html") Can any of you please suggest what function to use?

ANN: Core Session Tracking 0.7
by Chris McDonough 30 Jan '01

30 Jan '01

A new release of the "CoreSessionTracking" product is out. The product allows you to associate state with anonymous visitors between requests. The latest version (0.7) fixes a fairly serious kid-clicking-related bug found by Randall Kern that effects RAM-based ("internal") session data containers. If you need to upgrade from 0.6, all that is required is to untar/ungzip this release on top of the 0.6 release files. Then you must restart. You can find the product at http://www.zope.org/Members/mcdonc/Products/CoreSessionTracking/index_html - C

This kind of thing is a "query-on-metadata" application; I would put all these images into a single folder (maybe chunked into subfolders by month?), mark them each with an 'effective' property (of type 'Date'), and then select the appropriate image via a catalog query, e.g.:: <dtml-in "Catalog( meta_type='Image' , effective=( ZopeTime().earliestTime(), ZopeTime().latestTime() ) , effective_usage='range:min:max' # other query parms here, including any sorting... )"> <dtml-if sequence-start> <dtml-var "Catalog.getobject( data_record_id_ )"> </dtml-if> </dtml-in> Or you could just have the catalog fetch the images sorted by effective/descending, and then pick off the first one; this would keep an image around until supplanted by a newer one.
