Re: [Zope] Concurrent access with Apache and Zope
by Oliver Erlewein 05 Oct '01

05 Oct '01

Hi again I played arround with threads and the interval options of Zope. I've started Zope with "-t 13" and "-i 10". Somehow this seems to help somewhat with concurrent access. Now I'd like to know why. I couldn't find a clear explanation. Maybe somebody can help and give me insight. If there are other solutions / hints out there I'm interested!

As Code Red/Nimda use their own "client" implementation AFAIK, it surprises me that they follow redirects. Are you sure that this really helped for Code Red? How do you measure if it helped? Are you sure you just don't see Code Red requests anymore because it just got extinguished by Nimda? cheers, oliver

restrictedTraverse
by Julián Muñoz Domínguez 05 Oct '01

05 Oct '01

I was doing a little test on zope 2.4.1, and the method restrictedTraverse(path, default=None) doesn't give None if it doesn't find the object and you don't specify None on the second parameter, as it could be waited reading the Zope Book (page 286) (I'm newbie, not sure) -- __o _ \<_ (_)/(_) Saludos de Julián EA4ACL -.-

Widgets from PropertySheet items
by Douwe Osinga 05 Oct '01

05 Oct '01

Hi, I have a ZClass with a PropertySheet and now I want to create a form with some of these fields so that the user can edit the values. manage_createEditor returns a form with all the fields for a PropertySheet and does this by calling _edit_widget_for_type. _edit_widget_for_type basically does what I want, but is private. Is there some other smart way to achieve this? Douwe Osinga Oberon Medialab Keizersgracht 639 1017 DT Amsterdam tel. +31-20-3449487 dmo(a)oberon.nl http://www.oberon.nl

Re: [Zope] Test whether ZClass lines type property is empty
by complaw＠hal-pc.org 05 Oct '01

I've had this problem too. Instead of checking for length, I check to see if the first item on the list is <> ''. If there is nothing in the first item, then I assume that it is an empty list. For the most part, the assumption is valid. for x in my_list: if x <> '': # do something...

Help with Zope Install Errors?
by Michael Thomas 05 Oct '01

05 Oct '01

I am running into errors while trying to install Zope on a RedHat 7.1 servers. I have tried installing Zope on two servers and get the same errors on both servers. I want to run Zserver as a separate server apart from the Apache web server which is running on port 80. I am installing the Zope-2.4.1-linux2-x86.tgz binary. Can anyone help me? When I run ./install, I get the following errors: Compiling python modules File "/usr/local/zope/lib/python2.1/test/nocaret.py", line 2 [x for x in x] = x SyntaxError: can't assign to list comprehension SyntaxError: from __future__imports must occur at the beginning of the file (test_future3.py, line 3) SyntaxError: from __future__imports must occur at the beginning of the file (test_future4.py, line 3) SyntaxError: from __future__imports must occur at the beginning of the file (test_future5.py, line 4) SyntaxError: from __future__imports must occur at the beginning of the file (test_future6.py, line 3) SyntaxError: from __future__imports must occur at the beginning of the file (test_future7.py, line 3) Then, it seems to creates the inituser, default database, pcgi resource file, start script, and stop script without error. When I run ./start, the Zserver seems to start. I receive instructions about :8080 and :8021 ports, but then I get the following error: PANIC (300) x2 Startup Exception Traceback (innermost last): File /usr/local/zope/z2.py. line 757, in ? IOError: [Errno 13] Permission Denied: '/usr/local/zope/var/Z2.pid' I have doubled check the permissions. Every file under /usr/local/zope/ is owned by root:users. What might be going on? Of course, when I try to open the zope program via a web browser, the error says that the server was not located.

RE: [Zope] Core Session Tracking 0.9 Released
by Schmidt, Allen J. 05 Oct '01

05 Oct '01

Hey Chris, We have just started using Silesian recently and will soon be using Sessions from it site-wide. It was dirt easy to setup and start using. Can you offer any comparisons to it and CST inn terms of ease of installation, use, management, etc.? It would be nice to see the comparisons from an expert before we dive into Silesian big time! I would hate to have to redo it all 6 months down the road. ANYTHING you or anyone else can offer on this topic or on using Zope Sessions is MUCH appreciated! Thanks Allen -----Original Message----- From: Chris McDonough [mailto:chrism@digicool.com] Sent: Friday, October 05, 2001 2:31 AM To: zope(a)zope.org; zope-announce(a)zope.org Subject: [Zope] Core Session Tracking 0.9 Released Hi Folks, A new version of the Core Session Tracking product (the first one in six months!) has been released. Core Session Tracking is a Product which allows you to easily associate transient data with anonymous users. The product is available from http://www.zope.org/Members/mcdonc/Products/CoreSessionTracking. To upgrade from prior releases, just remove the "old" CoreSessionTracking product directory and install this one as per the install instructions in the help/CoreSessionTracking.stx document. A list of changes since the last version is: - Took advantage of securityinfo module and new BTrees modules. As a result, CST 0.9 is incompatible with releases of Zope prior to Zope 2.3.2. - Objects are now acquisition-unwrapped before being placed into session storage (thanks to Matt Hamilton) - A SessionData object's __setitem__ may now be called from a Python Script, it failed previously with a security error. - Fixed bug in SessionDataManager security assertions which made it impossible to change security parameters (thanks to Uwe C. Schroeder). - Fixed constructor number of parameter bugs (thanks to Chris Withers). - Fixed bugs that made isTokenFromForm, isTokenFromCookie, and isTokenNew methods virtually useless (thanks to Frank Tegtmeyer). - added flushTokenCookie method, which deletes the token cookie from the client browser with prejudice. This method is useful when you want to start out completely fresh with a different token. - Fixed bug which caused a "TypeError: loop over non-sequence" at startup under Zope 2.4.X in the Interfaces module which caused the product to not be initialized properly. (Thanks to Chris Withers and Joachim Werner). - Added multithread test cases to testSessionDataManager. - SessionFanout _getleaf method made more efficient by making allowed_hashes a dictionary (thanks to Anthony Baxter). - Added 'getName' alias to SessionData's 'getId' method for compatibility with code written for SQLSession (thanks to Anthony Baxter). - SessionDataContainer keys are now required to be strings (thanks to Anthony Baxter). - Added a new method to SessionDataManagers, "getSessionDataByKey", which provides a way to obtain an arbitrary session data object by feeding it a key (as opposed to getSessionData, which always obtained the session data object related to the current token). A user needs to possess a special permission to be able to do this. - Added conflict resolution to (RAM-based, internal) SessionStorage. - Made internal data container use "LowConflictConnection" class for its ZODB connections. This class operates differently than the standard Connection class because it doesn't raise "read" conflict errors. - Removed "AutoExpireMapping" class and merged its functionality into SessionDataContainer. - Removed "SessionFanout" module (unecessary because we're not trying to support pre-2.3.2 Zopes). - Refactored tests slightly. - Added SessioningPermissions and common modules.

RE: [Zope] How slow are Transparent folders?
by sean.upton＠uniontrib.com 05 Oct '01

I don't think they are slow, in that they just patch the way that namespace traversal is done and add a few namespaces... but they are definitely buggy; they will break CoreSessionTracking if you want to use more than one session id manager, among other things...
