Hi Uwe, Thanks for the concise explanation of the problem... I'm cc'ing the Zope list on this... it's best to keep this stuff on the Zope list because the message archive helps other folks out (including me! ;-) I think what's happening here is that the dtml-raise in the middle of the first snippet of DTML below aborts the ZODB transaction, and so the session data is never saved... Is there a way to prompt for authorization without doing a DTML raise? I've never used LoginManager... ----- Original Message ----- From: "Uwe C.

Hope that's ok. I installed the CoreSession (recent version) on an unmodified Zope 2.3.1 installation. I created a session_id_mgr in the root folder. Besides this on (also in the root folder) i created a session data manager called SessionManager. What I'm trying to do is to use the session information in conjunction with the loginmanager to authenticate users based on session information (this is a customer necessitiy for some special reason). In my login dialog i placed the following dtml - code <:let data="SessionManager.getSessionData(create=1)"> <:call "data.set('Path',PATH_INFO)"> <:call "REQUEST.set('token',SessionManager.getToken(create=0))"> </:let> <dtml-raise "'LoginRequired'">  <:if "SessionManager.isTokenNew()"> <font class="FontWhite">New Token created</font><br> </:if> <:let data="SessionManager.getSessionData(create=0)"> <font class="FontWhite"> Path is <:var "data.get('Path')"><br> <:var "SessionManager.encodeUrl(SCRIPT_NAME)"><br></font> </:let> where the lower two <let> constructs are for debugging only and will be removed later. The both lower constructs output the data set above as expected. In the same page is a form for auth. It now looks like <form method="post" action="http://tiburon.i.contrada.de:8080/Beta/B_Fachkreise/DocCheckHandler" > <input type="hidden" name="<:var "SessionManager.getTokenKey()">" value="<:var token>"> < Here the rest ot the form > The object DocCheckHandler gets called as expected and the getToken() method returns the correct token as expected. BUT - there is no session data object available. The code of the DocCheckHandler looks like <dtml-var standard_html_header> <h2><dtml-var title_or_id> <dtml-var document_title></h2> <p> The token is <:var "SessionManager.getToken(create=0)"><br> <:if "SessionManager.hasSessionData()"> <:let data="SessionManager.getSessionData(create=0)"> Pathinfo: <:var "data.get('Path')"><br> items: <:var "data.keys()"><br> </:let> <:else> No Data Container </:if> </p> <dtml-var standard_html_footer> The token gets output as expected, but I never get a data container. I tried this with internal and external data storage. I never get the session data back. Am I stupid or did I miss something ? Your help is appreciated Regards Uwe C. Schröder - -- Uwe C.

copying images + hit or save detection in Zope ?
by Jason Cunliffe 16 Apr '01

16 Apr '01

Q1. Is there any reliable way to know if someone has copied an image, a file or saved an HTML page from their browser using "Save as.." or similar? Q2. If yes, how would you suggest using Zope to catch events and store statistics on this. Create a ZCatalog with an updated 'saved_hits' property for each item would be ideal. Q3. Whether it is possible or not, how would you suggest using Zope to keep count of hits to Zope pages/objects? The application is a Zope site with a lot of graphics. Contributers [Artists] will upload often, according to their schedules and whims. Designing for ecletic low-maintenance freedom here.. There will be gallery and styudio areas for browsing the art. Instead of making people jump through a bunch of tedious form actions to get their images adn to store download data on the server, I thought it might be friendlier to just tell them 'save as..' any ideas? --Jason ___________________________________________________________ Jason CUNLIFFE = NOMADICS['Interactive Art and Technology']

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] Cobalt cubes and Zope
by Luke Tymowski 16 Apr '01

16 Apr '01

hello, > I was wondering if Cobalt and Zope are compatible. I may wish to run my Zope application on a Cobalt cube but it currently is not configured to run Zope. It comes pre-installed with Apaches 1.3. Any known issues? Perhaps there is a company that provides a turnkey zope+Apache solution. Also, I'm sure that is is possible to run multiple sessions of Zope. Can someone direct me to where this information is kep. I checked the database for ISP stuff but did not find exactly what I need. it depends on which Qube you're going to use. a Qube1 is barely usable by a handful of people; a Qube2 is ok for development and a small web site; a Qube3 is ok for several thousand visitors a day. the above assumes you're running Zope on a Qube. A Qube publishing static pages can support more viewers. also keep in mind that if you recompile Apache you risk breaking your warranty. I have a Qube1 and Qube2. Both can run Zope. Neither well enough for me to run a public web site. luke

Re: [Zope-dev] REQUIRING Python 2.1??
by Cary O'Brien 16 Apr '01

16 Apr '01

A small comment on the zope upgrade to requiring Python 2.1 One to think about is who will be effected, and how... New users w/ windows/nt: They have to download and install python anyhow, so is it any harder to get the latest version? If you search google for "download python" and take the easiset path, which version do you end up with. Existing users w/ windows/nt: How hard is it to have both versions of python running on one machine [I have no idea]. New Linux users: This may be the hardest group. They will already have Python 1.5 installed, and may not really understand installing rpms and stuff like that. Existing Linux users: Some will have no problems with a new version of python, others may be confused. Other Unix users: These people probably know enough to handle the python upgrade. So... 1) Someone with lots of Win/NT/W2k experience needs to figure out how to support 2 pythons and new/old zopes. 2) Instructions for downloading Python 2.1 should be made very clear. Perhaps even with links at the zope download site. 3) Common error cases (I guess that would only be new zope/old python) should provide very clear error messages on all platforms. 4) People on the zope list should have canned replies ready to go for the inevitable. 5) DC should put the right spin "upgrade takes advantage of exciting python 2.1 features such as ..." on the upgrade and get the information out into the electronic press. Fire away... -- cary

objectItems() question
by Ben.Peter＠t-online.de 16 Apr '01

16 Apr '01

Hello all, I am utterly confused: The following piece of dtml in standard_html_header <dtml-in "objectItems()"> <a href="<dtml-var absolute_url>"><dtml-var title></a> <dtml-unless sequence-end><br> </dtml-unless> <dtml-else>No items. </dtml-in> will yield a complete list of objects in the current container if there is a DTML Method 'index_html' available. If that is not the case, it will print 'No items.', even if there is a DTML Document index_html and any number of other Items, like folders. Is this intentional or (which I believe it'll turn out to be) am I blind again? Thanks for your help, Ben -- Ben Peter - Feldstrasse 8 - 35091 Coelbe Ben.Peter(a)t-online.de ph: (+49) 6421 983520

Filter Export
by Tim Cook 16 Apr '01

16 Apr '01

Has anyone tried to filter .zexp files to only contain a specific meta-type? For example: I have an application with instances of MyMetaType ZClasses in a folder. MyMetaType's are containers. I want to only export the MyMetaType objects AND everything they contain. Would I have to build a complete export module for this (that's what I'm guessing)? -- Tim Cook, President - FreePM,Inc. http://www.FreePM.com Office: (731) 884-4126 ONLINE DEMO: http://www.freepm.org:8080/FreePM

Calling dtml method from search result
by Byron C. Servies 16 Apr '01

16 Apr '01

Hi there! How do I call a DTML method that I have acquired as a result of a ZCatalog search? I can get the path to the method from the catalog, but I cannot figure out how to actually call the method and put the output in the output for the results page. I'm certain this is a common question, but I seem incapable of finding anything on zope.org, in the zope book, or in the mail list archives on the subject. A pointer, please? Thanks from a newbie, Byron
