Zope X3 3.0.0 alpha 2 released
by Stephan Richter 28 May '04

28 May '04

Hi everyone, The Zope 3 development team is proud to announce the second alpha release of Zope X3 3.0.0. Zope X3 is the next major Zope release and has been written from scratch based on the latest software design patterns and the experiences of Zope 2. The "X" in the name stands for "experimental", since this release does not try to provide any backward-compatibility to Zope 2. Download http://zope.org/Products/ZopeX3 Installation instructions for both Windows and Un*x/Linux are now available in the top level README.txt of the distribution. Changes since alpha 1 - Several packages were included in the first alpha since other code had several dependencies on their interfaces. This code has been refactored into sub-packages which are no longer part of the release. As a result, this distribution has fewer packages than alpha 1. Excluded packages include the indexing and fssync. - Some bugs were fixed that were reported by testers. This includes problems with the installation of a distribution. Goals While the first alpha release concentrated on testing our packaging tool and putting a process for releases into place, we would like to ask anyone to test this release a thoroughly as possible. The next release will be the first beta (probably next week) at which time the API freezes! Even if you are not interested in Zope you should test the building process of the distribution, since the packaging tool might be of great interest to the entire Python community. Please send any bug reports and comments to zope3-dev(a)zope.org! Thank you very much in advance for your help!

RE: [Zope] Help! Serious performance problem! (PTS? Zeo? SMP?)
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 28 May '04

Dieter, It's OK, I figured it out ... It's odd, once the leak stopped, the performance got worst. But it was partially due to me. I managed to make a variety of tweaks and changes that solved the problem, and it's running faster than ever now! While I've got your ear ... Is it possible to prefetch objects in the threads' object cache? So that instead of loading objects on demand, I could force the loading at start-up? I have some well know sets of objects that I'd like to have this done to, helping the startup time ... And possibly also allowing better indication of memeory usage. (It's a high traffic website with agressive caching, it can be slow after startup for a while, I'd like to see if that can improved). Thanks AGAIN, I owe you :) J.F. -----Original Message----- From: Dieter Maurer [mailto:dieter@handshake.de] Sent: May 27, 2004 1:53 PM To: Jean-Francois.Doyon(a)CCRS.NRCan.gc.ca Cc: zope(a)zope.org Subject: Re: [Zope] Help!

Product problems
by Richard Halldearn 28 May '04

28 May '04

Hi, I'm trying to build a custom Product using archetypes and so far I have been very successful. However, now I'm trying to set the vocabulary for one of the products to a DisplayList of all the objects of a particular type in my ZODB. The problem is I have no idea how to search for them. The code is here: http://authors.aspalliance.com/aylar/ViewPasteCode.aspx?PasteCodeID=2632 I'm using ZopeFind() but it is not returning anything. My guess is that I'm not using it correctly! Any ideas? Richard --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com) Version: 6.0.449 / Virus Database: 251 - Release Date: 27/01/2003

Does zServer provide any capability comparable to Apache httpd's 'piped logs' -- writing log files through a pipe to another process rather than a file? Thanks, Bill Etheredge The Mesa Group

WebDrive V6 (&5?) and Zope
by Paul Browning 28 May '04

28 May '04

Question: Is anyone using Webdrive V5 or V6 successfully with Zope? Either I'm missing something obvious or WebDrive V6 (and V5?) has become broken with Zope. Everything used to work for me with WebDrive V3 and V4. The following observations were made against Zope 2.7.0. The problem: You connect via WebDrive but you can't see any objects in the right hand pane of Windows Explorer. This happens for both anonymous and authenticated users (I even briefly granted the anonymous users every Zope permission - still no success). If you Show Monitor in WebDrive you see a problem: Connecting to http://zopebox.bris.ac.uk ... OPTIONS / HTTP/1.1 Host: zopebox.bris.ac.uk User-Agent: WebDrive/6.02 NT DAV Translate: f Connection: close HTTP/1.1 200 OK Server: Zope/(Zope 2.7.0, python 2.3.3, win32) ZServer/1.1 Date: Wed, 26 May 2004 04:58:20 GMT Content-Length: 0 Connection: close DAV: 1,2 Ms-Author-Via: DAV Connection: close Etag: Allow: GET, HEAD, POST, PUT, DELETE, OPTIONS, TRACE, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, UNLOCK Date: Wed, 26 May 2004 04:58:20 GMT Connected to http://zopebox.bris.ac.uk Get directory / Can't get directory Get directory / Can't get directory etc etc If you force an authenticated connection from the Windows command line: WebDrive.exe /s:"AAAtest" /u:paul /p:password /url:http://zopebox.bris.ac.uk /pr:1 /d:W /nosaveuserinfo /exp you see in the Zope log just the one entry: 82.32.6.79 - Anonymous [26/May/2004:05:43:05 +0100] "OPTIONS / HTTP/1.1" 200 355 "" "WebDrive/6.02 NT DAV" Do the same thing from Cadaver (which works just fine) and you see four transactions: 137.222.120.80 - Anonymous [26/May/2004:05:46:11 +0100] "OPTIONS / HTTP/1.1" 200 336 "" "cadaver/0.19.1 neon/0.18.3" 137.222.120.80 - Anonymous [26/May/2004:05:46:11 +0100] "PROPFIND / HTTP/1.1" 401 615 "" "cadaver/0.19.1 neon/0.18.3" 137.222.120.80 - paul [26/May/2004:05:46:15 +0100] "PROPFIND / HTTP/1.1" 207 895 "" "cadaver/0.19.1 neon/0.18.3" 137.222.120.80 - paul [26/May/2004:05:46:16 +0100] "PROPFIND / HTTP/1.1" 207 10935 "" "cadaver/0.19.1 neon/0.18.3" Now I'm no WebDAV guru but it would seem that Anonymous needs to do a PROPFIND before a successful authenticated user access can occur - and this is not happening with WebDrive V5/6 against Zope. Any insights appreciated. Thanks Paul -- The Library, Tyndall Avenue, Univ. of Bristol, Bristol, BS8 1TJ, UK E-mail: paul.browning(a)bris.ac.uk URL: http://www.bris.ac.uk/
