ANNOUNCE: Pound - reverse proxy and load balancer - v1.8
by Robert Segall 04 Nov '04

04 Nov '04

This is to announce the release of Pound v1.8. Changes in this version: - added support for non-blocking connect(2) - added support for 414 - Request URI too long - added RedirectRewrite directive - to prevent redirect changes - added support for NoHTTPS11 value 2 (for MSIE clients only) - added support for HTTPSHeaders 3 (no verify) Problems fixed: - fixed bug if multiple listening ports/addresses - fixed memory leak in SSL - flush stdout (if used) after each log message - assumes only 304, 305 and 306 codes to have no content - fixed problem with delays in 302 without content - fixed problem with time-outs in HTTPS Enhancements: - improved threads detection code in autoconf - added supervisor process disable configuration flag - tweak for the Location rewriting code (only look at current GROUP) - improved print-out for client certificate information The software is at version 1.8 (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 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

Hi What's the common method to detect a session timeout to display an error page to the client? I tried getBrowserIdManager().hasSessionData() but this doesn't work. Regards Beat H.

APE/custom product question
by Adam J Smith 03 Nov '04

03 Nov '04

I have started experimenting with APE and I think its great. I am just having a small problem saving a class of objects from a custom product I wrote. I suspect the ultimate answer is to write my own serializer, but before I go too far in that direction, I thought I would see if anyone could point me to a lazier solution. In this product, most of my classes subclass the OrderedFolder object and use the PropertyManager, so the default APE filesystem configuration seems to handle them perfectly. In one case though, I subclass both OrderedFolder and OFS.Image (and in another case, both OrderedFolder and OFS.File). This works fine with plain-old ZODB, but generates the following error when I use APE: --- Traceback (innermost last): Module ZPublisher.Publish, line 100, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 40, in call_object Module Products.TutorialAuthor.taFile, line 68, in manage_addtaFile Module Products.TutorialAuthor.taFile, line 131, in handleUploadedFile Module OFS.Image, line 434, in manage_upload Module OFS.Image, line 483, in _read_data Module ZODB.Transaction, line 233, in commit Module ZODB.Transaction, line 348, in _commit_objects Module apelib.zodb3.connection, line 287, in commit Module apelib.zodb3.connection, line 411, in _handle_unmanaged AssertionError --- I suspect that APE is trying to save it as a folder, and doesn't expect the file data, or something like that. (In the class spec, I inherit from OrderedFolder first, then Image.) I am double-checking my code just to make sure that I am not doing something wrong that is just now coming to light, but otherwise, I am wondering how much hope there is for finding a way to make the default filesystem configuration work. I'm using Suse 9.1, Zope2.7.0, Python 2.3.3, and Ape 1.0. (Would Zope 2.7.3, Python 2.3.4 make a difference?) Thanks in advance for any guidance... ____________________________ adam smith ajs17(a)cornell.edu

[ANN] HTMLDocument 1.0 released
by Maik Jablonski 03 Nov '04

03 Nov '04

Hi, for all people who are (mis;))-using the Zope Mangement Interface (ZMI) as small, but very powerful, flexible and rock-stable Content-Management-System, I've just released HTMLDocument 1.0 (which I use for several years now). HTMLDocument supports WYSIWYG-editing of HTML-content with Epoz (http://mjablonski.zope.de/Epoz) and renders its content (just the body of an edited or uploaded HTML-page) automagically with the famous combination of standard_html_header / standard_html_footer (DTML) or a single standard_html_template (ZPT). So all your content can be seperated from any template-logic and you'll setup an easy-to-use-and-very-flexible CMS-solution based on the ZMI within minutes. Create a template for your site, create a folder (for seperating your content from templates and other scripts), create some HTMLDocuments in this folder, click view and you're online...:) HTMLDocument is a simple solution for all people who don't need or want a big suite like Plone / CPS or want a stable (and easy to upgrade) basement for their content: HTMLDocument should work out of the box as long as Zope supports the builtin DTMLDocument on which HTMLDocument is based. "Download":http://mjablonski.zope.de/HTMLDocument Keep zoped, Maik

apache+zope in lan
by kevinthackray＠free.fr 03 Nov '04

03 Nov '04

Dear all, I am pretty new to zope and the only thing i can't do right now to have my zope running with the apache front end configuration : I know there are a lot of tutorial, i followed then, but nothing can't do, here is my problem : I have a webserver in my lan, and an openBsd as my gateway. On my openb, i have a firewall (pf) which forward only the port 80 (blocks 8080). Here is my apache configuration : ############################ NameVirtualHost * <VirtualHost *> DocumentRoot /var/www/htdocs ServerName keke.epaveman.com RewriteEngine On RewriteRule ^/zope/(.*) http://localhost:8080/$1 [P,L] ProxyVia on ErrorLog /var/log/apache/zope-error_log CustomLog /var/log/apache/zope-access_log common </VirtualHost> ############################ My problem is, the firt hit is ok, but all the links are towards the base url : http://localhost:8080/... With the apache proxy config, I get a "better" resultat : the links are towards the base url : http://keke.epaveman.com:8080/... (will be futher block by pf) I installed a plone if anyone want to test : http://keke.epaveman.com/zope/blog/ If anyone have some ideas that would be great because i really would like to use zope!!!! regards, kevin.
