ANN: TextIndexNG 2.03 released
by Andreas Jung 01 Dec '03

01 Dec '03

I just released TextIndexNG 2.0.3. This is an optimization release :-) and features a new internal hashing datastructure that avoids needless reindexing of objects that have not changed. This should improve reindexing performance significantly. Upgraders should reindex their TextIndexNG2 indexes after installation. This release is available from Sourceforge: http://sourceforge.net/project/showfiles.php?group_id=50052 Docs are available as usual from http://www.zope.org/Members/ajung/TextIndexNG -aj

Re: [Zope] ZPT and CSS
by Michael Havard 01 Dec '03

move your link down into the header macro section and see if it works then. I think what might be happening is that your "head" macro is not being pulled into the generated page at all. You should be able to view source and see if the link is even showing up in the page and if it is if maybe another style sheet comes after it that throws things off. I can say that CSS does work in ZPT because I use it every day. >From: Andre Meyer <a.meyer(a)hccnet.nl> >To: Zope Mailing List <zope(a)zope.org> >CC: Tino Wildenhain <tino(a)wildenhain.de> >Subject: Re: [Zope] ZPT and CSS >Date: Sun, 30 Nov 2003 23:48:53 +0100 >MIME-Version: 1.0 >Received: from mc8-f26.hotmail.com ([65.54.253.162]) by mc8-s6.hotmail.com >with Microsoft SMTPSVC(5.0.2195.6713); Sun, 30 Nov 2003 14:48:53 -0800 >Received: from mail.python.org ([12.155.117.29]) by mc8-f26.hotmail.com >with Microsoft SMTPSVC(5.0.2195.6713); Sun, 30 Nov 2003 14:49:21 -0800 >Received: from localhost.localdomain ([127.0.0.1] helo=mail.python.org)by >mail.python.org with esmtp (Exim 4.22)id 1AQaNB-00033g-S5; Sun, 30 Nov 2003 >17:49:01 -0500 >Received: from smtp.hccnet.nl ([62.251.0.13])by mail.python.org with esmtp >(Exim 4.22) id 1AQaN6-00033B-Lpfor zope(a)zope.org; Sun, 30 Nov 2003 17:48:56 >-0500 >Received: from [10.0.0.13] by smtp.hccnet.nlvia fia27-95.dsl.hccnet.nl >[62.251.95.27] with ESMTPid hAUMmsgt003932 (8.12.10/2.03); Sun, 30 Nov 2003 >23:48:54 +0100 (MET) >X-Message-Info: pdGgd64Ckwb64bDCBiLbou2ARrp6rGbVBWG9E59sdxI= >In-Reply-To: <3FCA3C4A.7070300(a)wildenhain.de> >References: ><1070188751.13695.4.camel(a)localhost.localdomain><3FC9EB73.4020703(a)wildenhain.de><1070215826.13695.16.camel(a)localhost.localdomain><3FCA3C4A.7070300(a)wildenhain.de> >Message-Id: <1070232533.13695.20.camel(a)localhost.localdomain> >X-Mailer: Ximian Evolution 1.4.5 (1.4.5-7) X-Spam-Status: OK (zopelist >0.000) >X-BeenThere: zope(a)zope.org >X-Mailman-Version: 2.1.3 >Precedence: list >List-Id: Users of the Z Object Publishing Environment <zope.zope.org> >List-Unsubscribe: ><http://mail.zope.org/mailman/listinfo/zope>,<mailto:zope-request@zope.org?subject=unsubscribe> >List-Archive: <http://lists.zope.org/pipermail/zope> >List-Post: <mailto:zope@zope.org> >List-Help: <mailto:zope-request@zope.org?subject=help> >List-Subscribe: ><http://mail.zope.org/mailman/listinfo/zope>,<mailto:zope-request@zope.org?subject=subscribe> >Sender: zope-bounces(a)zope.org >Errors-To: zope-bounces(a)zope.org >Return-Path: zope-bounces(a)zope.org >X-OriginalArrivalTime: 30 Nov 2003 22:49:22.0038 (UTC) >FILETIME=[321E1160:01C3B794] > >Something else must be wrong here. > >It works find as long as the style information is inside the zpt page, >but referring to an external css file does not work for me.

ANNOUNCE: Pound - reverse proxy and load balancer - v1.6
by Robert Segall 30 Nov '03

30 Nov '03

This is to announce the release of Pound v1.6. Changes in this version: - Callback for RSA ephemeral keys: - generated in a separate thread - used if required this will allow certain versions of IE to work correctly with Pound/SSL. - New X-SSL-cipher header encryption level/method - Added CheckURL parameter in config file - perform syntax check only if value 1 (default 0) - Allow for empty query/param strings in URL syntax - Additional SSL engine loading code - Added parameter for CA certificates - CA list is sent to client - Verify client certificates up to given depth - Fixed critical security vulnerability in syslog handling: this may allow a remote exploit, though none has been observed to date. The danger is minimised if you run Pound in a root-jail and/or as non-root user. Anyone using a version prior to 1.6 should upgrade as soon as possible. The software is at version 1.6 (production quality). Further testing (especially under heavy loads), improvements and suggestions are welcome. What is Pound (from the Web page) - a reverse-proxy: it passes requests from client browsers to one or more back-end servers. - a load balancer: it will distribute the requests from the client browsers among several back-end servers, while keeping session information. - an SSL wrapper: Pound will decrypt HTTPS requests from client browsers and pass them as plain HTTP to the back-end browsers. - an HTTP/HTTPS sanitizer: Pound will verify requests for correctness and accept only well-formed ones. - an HTTP/1.1 to 1.0 proxy. - a fail-over-server: should a back-end server fail, Pound will take note of the fact and stop passing requests to it until it recovers. - a request redirector - it will pass client requests to separate groups of servers, based on required URL and the presence or absence of headers (pattern matching) Pound was specifically developed to serve as a front-end for multiple instances of Zope running on top of a common ZEO storage, but can be used with any other web server. A patch for the Python source of z2.py is available as part of the distribution to allow using Pound's SSL capabilities. Pound is currently in use in several medium to large volume sites and seems to be holding up quite well: largest reported site does about 5.5 million requests per day, peaking at over 450 requests per second. The speed is well superior to other, equivalent solutions, the configuration is much simpler and the necessary resources (CPU, RAM, disk) are much, much lower. Pound is distributed under the GPL. For further information, download, etc. please see http://www.apsis.ch/pound Pound now has its own mailing-list - just send a message to pound-subscribe(a)apsis.ch in order to join. Enjoy and let me know how it works for you. -- Robert Segall Apsis GmbH Postfach, Uetikon am See, CH-8707 Tel: +41-1-920 4904

Storing Roles in RDB with APE
by Elena Schulz 30 Nov '03

30 Nov '03

Hi, does anybody have experiences with storing roles in an external database with APE. What are possible problems with that. concerning stability, reliability etc. Are there other or better solutions storing roles externally. For the first step, only roles of one folder-object need to be stored. Is it possible, to store all roles of any folder externally. The informations about the roles should only be kept in the external database, so changes of the concerned table should change the roles in zope. -- Thanks for your answers, Elena

Using batch processing in DTML
by Mico Siahaan 30 Nov '03

30 Nov '03

Hi, suppose I have folder gallery that contains 40 photos. I want to make a DTML page that previews these photos. Suppose I want to load 15 photos each view and I want to arrange that 15 photos into 5 columns and 3 rows format... how do I accomplish that? I have read the example in Zope book about batch processing, but in my case I guess I have to make other loops in the batch loop ( 2 more loops I guess). But I am confused about the inner loops: over what object should the inner loops interate? Thanks. -- Mico Siahaan ------------- mico(a)intermatik.co.id

Catch Object Changes
by Holger Schmidt 30 Nov '03

30 Nov '03

Hello, I have a list of objects. The list can contain objects like Folders, PropertyObjects or just every product that you have installed (but has to be accessible via the ZMI). My problem is that I want to do some XML-RPC to another Zope instance whenever some object of my list has changed (the XML-RPC depends on the object which has changed, that means that I also need to get the (commited?) changed object at this time). My idea to solve this problem: 1.) get to know when ANY object in Zope is changed 2.) check if this object is in my list 3.) if the list contains the object: start a thread managing the XML-RPC Problem is step 1 ... how can Zope tell me that ANY object is changed ...? I've heard that one solution would be to write my own storage but this would be very difficult ... Is there also an easier solution to my problem? -- Thanks, Holger P.S.: I probably will not manage to read any mail this weekend but would be very happy if I would receive (m)any solutions until sunday evening ;)

ZPT and CSS
by Andre Meyer 30 Nov '03

30 Nov '03

Hi Zopers Trying to improve my ZPT pages I wanted to make use of Cascading Style Sheets (CSS). While the styles in my CSS file are properly rendered when I open the HTML file directly in the browser (Mozilla 1.4.1) they completely disappear when I view the same page through Zope!!! What is Zope doing? May it be that the CSS cannot be located because of the base url inserted by Zope? best wishes Andre
