Zope still 'hanging' - LinuxPPC, 2.0b5
by Tony McDonald 22 Aug '99

22 Aug '99

Hi all, I posted a while back that Zope 2.0b5 seemed ok re: hanging under Solaris 5.6 using the binary release. That still seems the case, although I've not had a chance to batter the system yet, I'll be able to report better later in the week. However, I d/led the 2.0b5 source version for my LinuxPPC box at home and have built it in the same manner I have the other 2.0betas that I have (2.0b1 and 2.0b4). It still hangs for quite long periods of time, and it seems totally random to me. I'm afraid I can't really give you more information than that, but if someone tells me the magic to type, I'll do so and report back. tone.

Multiples python error?
by Andreas Kostyrka 22 Aug '99

22 Aug '99

Hi! I've been fooling around with a new RH6.0 box here and I've installed python and ZOPE in a /opt directory. Well, pcgi doesn't like that to much, but this is not what this is post is about: Zope version: Zope 2.0.0b5 (source release, python 1.5.1, linux2) Python version: 1.5.2 (#1, Aug 19 1999, 19:28:50) [GCC egcs-2.91.66 19990314/Linux (egcs- System Platform: linux2 Process ID: 5143 Running for: 21 hours 4 min 34 sec Well, I'm just wondering where does this python 1.5.1 come from? RH6.0 does come with a python 1.5.1 in /usr, but this ZOPE installation doesn't use it at all.

Re: [Zope-dev] the right way to do wiki in zope ?

In another thread, Anthony wrote: > Question: Can we make ZClasses directly on ZPT? Ditto. If not, I wondered if one could actually hack wiki functionality on there using nothing but DTML. I'm not yet convinced you couldn't. Zclasses - mindbending stuff. I did some experimenting on my local server, and here's where I'm at. I made a Zclass called WikiDTMLPage, based on DTML Document. I gave it an index_html method which translates words which match the wiki link pattern to relative hyperlinks, this way: <dtml-var "_.ts_regex.gsub( '\([A-Z]+[a-z]+[A-Z][A-Za-z]*\|[A-Z][A-Z]+[a-z][A-Za-z]*\|_[\\\w.:_]+_\)', '<A HREF=\\1>\\1</a>', data) "> data is a zclass property I added; I'd rather use the DTML document's existing data attribute but couldn't find the right syntax. I added ts_regex to the DTML namespace - DC, is there any reason not to provide ts_regex or re to DTML users ? Regexps are darn useful. This allows you to create & edit wiki pages, displays the links, but doesn't help you create new pages of course. A helper external method for this class seems like a good way to go. > Once I fix up the namespace mangling that Zope is doing (and which > prevents freezing it - python is already frozen) I'll whip up a ZikiSpace.

I mean, it doesn't help you create them in the wiki way (mention a ANewPage somewhere and a question mark appears beside it, which will create the page when you click on it).

Session Product
by Scott Robertson 20 Aug '99

20 Aug '99

I just uploaded an Experimental Sessions Product to the Contrib section on zope.org. This is code I was using to explore the concept of users session/shopping carts for the upcoming ZCommerce API that I'm working on. It's no where near done, I want to get back to writing the API docs, but I thought some of you might get a kick out of it. Here's a teaser from the comments in the source code: The Session Object WARNING!!! This is a reference implementation only. I wrote this to explore session concepts and to get a better idea of what I could or could not do with Zope's security model. This code by no means is complete pretty or even that useful. But it has proven that the session concept is valid. What is a session? A session object is an object that behaves like a folder in zope. If you access <Session FolderId>/docLogin via the web, the session folder will validate your username and password based off of the first acl_users folder that it finds via acquisition. Once the user has been authorized the Session Folder creates a brand new Session Instance and stores the user information in the Session Instance. Whenever an object is accessed through the Session Instance the user is equivalent to the user that originally logged in. In effect the authorization information is stored in PATH_INFO instead of a cookie or using standard HTTP authentication methods. Session Instances will/should be automatically deleted if the user has been idle longer than the time to live property. The advantages to this scheme are. (Of course most of this is not implemented in this sample) * A user can be logged in as more than one person at a time, without having to restart there web browser. * An admin can get a list of all the people currently logged into Zope. * You can limit the amount of times the same user id is logged into Zope at once. * The Session Folder should be able to use any type of acl_users folder, so authentication can be done against the User, UserDB, or UserLDAP already or any other custom User Folder. Because the user is only looked up once, Zope does not have to constantly go back to the data source for every page request and perform authentication like it does now. * Sessions can time out values so a user can be logged out if they are inactive for to long. i.e. They leave there computer unattended, they will be logged out. * Sessions can be used to store state information between web requests so that the user's current IP address can be stored within the session which can prevent people from hijacking sessions. Also makes it really easy to implement a shopping cart object. =) * The scheme is token based, which means that the user name and password aren't passed around in the clear, so it might be more secure. Of course the session would have to be created under SSL for maximum protection, but then once the session has been created the session could be accessed using normal HTTP for speed. * There's many more, but I'm tired of typing. --------------------------------------------------- - Scott Robertson Phone: 714.972.2299 - - CodeIt Computing Fax: 714.972.2399 - - http://codeit.com - ---------------------------------------------------

RE: [Zope-dev] 2nd of back-to-back communications with Zope hangi ng?
by Brian Lloyd 20 Aug '99

20 Aug '99

Hi Marc. I _think_ we've found a fix for this - I've attached a new select_trigger.py file that should replace the one in the ZServer/medusa directory of your installation. If you get a chance to drop this updated file in and restart your site (so that the change can take effect) can you let me know if this takes care of the problem? Thanks!

Z2B5 - would like a help button on the control panel
by Brad Clements 20 Aug '99

20 Aug '99

If DC is planning something terrific for help, great. Otherwise it would be nice to have the help button on the control panel to make it easier to find the product help. I understand why the help tab was removed, but a button on the control panel might be ok, unless there's something even more useful coming.. Otherwise, type in the URL <host>/Control_Panel/manage_help to get it..

Q: How to serve Files/Dirs as documents?
by Thomas Riedl 20 Aug '99

20 Aug '99

Hi there! After some interruption to my Zoperies (live's no mercy, right? ;-) I'm wondering about this: I'd like (for IMHO quite obvious reasons ;-) to have some mapping from my (Unix) filesystem to Zope objects, like I have directories with (DTML) files which I's like to 'render'. I'm thinking of quite regularly changing file content (due to events external to zope) along with a good deal of 'binaries' whose "meta informations" (version, author, notify-upon-change a.s.o.) are stored in the DTML files. It's also possible that vi-nics want to meddle with them (so, no Emacs EFS support for those boneheads). ( E.g. an User uses his browser to navigate himself to a some 'documentation area'. He then could see for all docs residing there their author, current version, last update time, approval by and all that. By clicking on a 'Document Data' button, his browser would e.g. start some 'version control' wrapper along with StarOffice. If there are changes, this very wrapper would rewrite the appropriate '*.dtml' file. ) A "Magic Black Box" Zope thing would then e.g. try to match an object path to directories, read something like '.properties'-files for each directory to represent folder properties and e.g. '.properties.file.dtml' for each leave object 'file.dtml' and of course use acquisition. ( Such a path might e.g. read '/Zope/Filemap1/home/thatsme/currvitae' and hit a 'currvitae'-File that contains something like 'This is ' and e.g. 'thatsme/.properties' containig a line 'me=My Real Name' Filemap1 according to my current idea would be a Product instantiation of my/some TBD "Magic Black Box FileAccess" product. ). Q's now are: Does this Make Sense? Is there something that could keep me from reinventing a wheel? Why wouldn't I like to do it this way? And which way is the Zen Way to go?

Hello, my name's Liart Satiro Costa Martins I'm a Web-Developer in Brazil, and recently I started work with the ZOPE to create a Portal-Site. But I have a greate problem: In my site I have a table with 2 colums, the heigth of this colums is variable. I create a program of administration for the user include a notice, the user can insert remote a notice and a image (of notice). I make a function in JavaScript what divided the notice in two parts to put the first part in the first colum of my table and the second part in the second colum of my table, but how a insert a determinated image the columns size don't make equals. And I nedd any function or propertie of ZOPE what return the size (widht an heigth) of any image.
