Protocol question about ZopeBook typos
by Perry Smith 25 Sep '06

25 Sep '06

Wonderful documentation but there are a fair amount of silly typos, etc. Do folks want me to open "issues" or "bugs" on these typos? Perry Smith Ease Software, Inc. pedz(a)easesoftware.com http://www.easesoftware.com SATA Products for IBMs RS/6000, pSeries, and AIX systems

unexpected keyword argument 'error'
by Pupeno 24 Sep '06

24 Sep '06

Hello, I am trying to make a Data.fs file work on my local workstation. I've download it from my server. My server runs Debian with Python, Zope and Plone installed from sources. My workstation runs Gentoo with Python, Zope and Plone installed from ebuild but the same versions as on the server: Python 2.4.3 Zope 2.9.4 Plone 2.5 I've put the Data.fs and started the local Zope. But no matter what I try to access I always get the error: Error Value: _log() got an unexpected keyword argument 'error' The whole error is: Site Error An error was encountered while publishing this resource. Error Type: TypeError Error Value: _log() got an unexpected keyword argument 'error' Troubleshooting Suggestions The URL may be incorrect. The parameters passed to this resource may be incorrect. A resource that this resource relies on may be encountering an error. For more detailed information about the error, please refer to the error log. If the error persists please contact the site maintainer. Thank you for your patience. and the error.log reveals: ------ 2006-09-24T16:34:06 ERROR Zope.SiteErrorLog http://phoenix.pupeno.com:8080 Traceback (innermost last): Module ZPublisher.Publish, line 106, in publish Module ZPublisher.BaseRequest, line 275, in traverse Module ZPublisher.BeforeTraverse, line 108, in __call__ Module logging, line 999, in error TypeError: _log() got an unexpected keyword argument 'error' I can't find any other useful information. Any ideas what the problem might be ? Thank you. -- Pupeno <pupeno(a)pupeno.com> (http://pupeno.com)

Newbie Question
by Perry Smith 24 Sep '06

24 Sep '06

Is it possible to have the same host running ZOPE 2 and ZOPE 3? I would like to put both on a Mac OS X server. I have Apache 2.2 running on it and PostgreSQL version 8.1.3 running my existing software. I'd like to add zwiki which uses ZOPE 2. And then add ZOPE 3 so that I can start developing a new application. Can all three of these coexist on the same machine? Are there any suggested do's and don'ts to follow in such an arrangement?

LocalFS - user needs to be manager?
by Josh Burvill 23 Sep '06

23 Sep '06

Hi all, I am experiencing an odd situation where if a user does not have manager role, he/she cannot browse a localfs object. I think it can't be a filesystem permissions or zope process os user problem because if the zope user has the manager role, there is no problem. I can't see anything in the permissions for the localfs object to cause a problem, they are all on "acquire". Any hints? Zope 2.8.6-final, python 2.3.5, win32 LocalFS-1-7-andreas Josh

by Ferhat Ayaz 22 Sep '06

Hi, I read every doc I found. But the server reports always 403 on konfiguring an APache VirtualHost on my Zope Instance on the same machine. Here my sniplet from apache2.conf (also known as httpd.conf) <VirtualHost journal.homelinux.net:80> ServerName journal.homelinux.net ServerAdmin myemail(a)yahoo.com RewriteEngine On RewriteRule ^/(.*) http://localhost:8080/VirtualHostBase/http/journal.homelinux.net:80/Virtual… [P,L] ErrorLog /var/log/apache2/journal-error_log TransferLog /var/log/apache2/journal-access_log </VirtualHost> I tryed many other variants to point to the VH Monster. The result is always: Forbidden You don't have permission to access / on this server. What am I doing wrong????????????????????????????????? thanks, Ferhat __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

RE: [Zope] Problem with running same script at a time

Thank you Dieter, I will try it. -----Original Message----- From: Dieter Maurer [mailto:dieter@handshake.de] Sent: Friday, September 22, 2006 8:03 PM To: Pletli Antal Cc: zope(a)zope.org Subject: RE: [Zope] Problem with running same script at a time Pletli Antal wrote at 2006-9-22 08:51 +0200: > ... >I have a demo user folder in my Zope project with two scripts.

I have to explain a bit that you can understand the problem. Zope's request processing has roughly two phases: URL traversal to locate the object identified by the URL and then calling the located object. At the end of URL traversal lies the user authentication. This proceeds as follows: Zope starts at the located object and looks upward (towards to root) to find a User Folder which is ready to authenticate the user with the required roles. It will ask each User Folder it finds above the object until one gives a positive answer. The highest user folder will always return a user, maybe the anonymous one. If your User Folder calls out to a backend system and this backend system calls back (via URL) into an area controlled by your User Folder, then you lose -- as the User Folder will again call out and wait for an answer before it will call the object... Move the thing called back out of your hiararchy dominated by the UserFolder. Then, you might have success. -- Dieter

RE: [Zope] Problem with running same script at a time
by Pletli Antal 22 Sep '06

Thank you Dieter! Here is the exact scenario, which in I first observed the problem: I have a external zope python module that communicates via TCP with a background system written in Java. I have a background system that communicates with the Zope via URL. I have a demo user folder in my Zope project with two scripts. The first script sends a tcp message to the background (with the help of external module), the second one do something when the background call it via url. First the Zope script sends a tcp message to background system, and waits for the reply. The background receives the message and try to call the url by http request, then if it is success replies to Zope script's tcp request. Here is the problem. The background system cannot access the URL until in the first script tcp timeout happen. When I move the second script into other outer folder, all is OK. It is very strange, and I'v never read from this problem before.

I had to fix a problem in "psycopg": During "connect", Python's Global Interpreter Lock (GIL) was not released (freezing Zope during connect). Usually, this is not a problem as "connect" is quite a fast operation. We noticed it only when the server for the postgres installation was down (then "connect" became a several minute operation until the TCP timeout happened). However, it is unlikely, that this is your problem. >The behaviour is the same when i >use long socket communication (as a tcp client), etc. This, too, should not happen -- and I never observed it (but a colleague reported something like this but never showed it to me -- and I did not believe him; or more precisly, I tested his alledgedly observed behaviour and could not reproduce it...) >In these cases the >folder wich contains the scripts be unaccessible. Unbelievable -- unless your folder access triggers the long socket communication. In this case, it would not be the old socket communication that "blocks" but the new one. Of course, your folder access should not trigger anything else... -- Dieter

Hi Dieter! Than you for your answer! I use the same product. This problem is one of the others... The behaviour is the same when i use long socket communication (as a tcp client), etc. In these cases the folder wich contains the scripts be unaccessible. Maybe have i a wrong zope configuration (i use default config)?

You might be using an unfortunate Postgres adapter library. We are using "psycopg" and do not observe this problem. -- Dieter

idiotic dreamweaver question
by David Bear 21 Sep '06

21 Sep '06

Sorry to bug this list with a dw question. However, I was using DAV in dw and found that dw is unable to handle file extensions like .pt, .zpt, _html , etc. Does anyone else use dreamweaver to edit zope/plone files? If so, how do you make dreamweaver edit this types of files? I know _html, .pt, .zpt etc are well formed xhtml -- but I don't know how to tell stupid dw to edit them since it uses the extension to recognize file type. -- David Bear phone: 602-496-0424 fax: 602-496-0955 College of Public Programs/ASU University Center Rm 622 411 N Central Phoenix, AZ 85007-0685 "Beware the IP portfolio, everyone will be suspect of trespassing"
