Zope cut & paste behaviour
by Ivo van der Wijk 16 Apr '01

16 Apr '01

Hi all, Zope seems to behave weird/inconsistently when copy/cut/pasting objects from folder (-objects) to folder (-objects). For one, it doesn't seem possible to move an object more up to the root (or anywhere not *below* the folder the object was cut/copied from). This is partially due to the fact that the __cp (clipboard) cookie has it's path set to it's originating folder. I.e move /foo/bar/a to /foo/a or to /blah/a Clipboards seem to be local to the folder. This may be related to the nature of cookies (with their path set to that the path of that folder), I'm not sure. If you cut 'a' in /foo/bar, then cut 'b' from / and try to paste 'b' in /foo/bar, you'll end up with '/foo/bar/a' again. And as it is not possible to clear your clipboard (esp which opera, which cannot clear cookies), it's very difficult to move objects in these circumstances. Is there any clear reason zope behaves this way? Are there any problems to be expected if the path of the __cp cookie is set to /, so your clipboard is visible everywhere? Could ZCatalog aware objects cause problems? I'd be willing to spend some time on fixing this if there's nothing that it would break. Cheers, Ivo -- Drs.

Threads Optimizing Linux.
by Aitor Grajal Crespo 16 Apr '01

16 Apr '01

Hello , my question is a bit complex ( for me ). I have : - Linux RH 6.1 - python 1.5.2 --with-thread (source compiled) - zope 2.2.x or zope 2.3.x (source compiled) In any program in python with Linux (inclusive Zope), the threads are processes,i.e, they consume memory and don´t share it. In Windows this is different. In Linux, I have Zope running with 4 Threads. I have five processes and everyone consuming about 12 MB => 12 * 5 MB = 60 MB In Windows in the same situation I only have one process and the threads share the memory, which is the most desirable situation. Why?? Does anybody know a solution for Linux, in order to have only one process and threads sharing memory, as in Windows?? Thanks.

RE: [Zope-dev] un-own an object

Maybe you should into them more. I think that they are underappreciated in the Zope world. Very rapid dev (although slower performance). A large part of the Python dev that I am doing is geared to making ZClasses more powerful. take a look at some of my proposals. The events in particular make ZClasses much more powerful. http://www.zope.org/Members/tmclaugh We've been using the event model for ZClass dev very effectively here at BCS. I'll be posting the event code soon.

Thanks Chris. PathHandler is indeed what I needed. But I have one last problem: It looks like I need to create a PathHandler object (called "ph" for instance), and then the url is www.website.com/ph/member_name What if I want it to work at the root of my website, like this: www.website.com/member_name ? Thanks.

Re: [Zope-dev] Query on ZODB handling of class variables
by Dieter Maurer 14 Apr '01

Bob Weiner writes: > ... > So how does one get class attributes (one attribute instance per class) > stored into and restored from ZODB? I fear, it will not go. But, you can take the object from the class and put it as an object with a specific name (maybe derived from the class name) into the ZODB. The class would provide methods to access this object in ZODB. Dieter

Re: [Zope-dev] REQUIRING Python 2.1??

My experience with the Python development process is very good. New versions contain few problems which are rapidly eliminated. I will switch to Python 2.1 (now using Zope with Python 2.0) immediately when it becomes available (has nice features, I fought for since a long time (nested namespaces)). You will only be affected for Zope 2.4. I think, it will take several month, before it is final. Dieter

There is excellent documentation about Zope 2.2 security. There, you should be able to check how reliable my memory is. Dieter

How to handle "special" sub-directories
by Remi Delon 14 Apr '01

14 Apr '01

Hi, I have a website where members can sign up. I want to give each of my members their own URL, in the format www.website.com/member_name But I don't want to create a Zope document for each member. Instead, I want to be able to find out what the member name is, and then fetch some data in my database based on the member name and then display it. This is like transforming the URL www.website.com/member_name into www.website.com/unique_document?arg=member_name How can I do that ? Thanks. Rémi. _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
