RE: [Zope] Core Session Tracking 0.9 Released

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?

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...

So far i had only the mailing list digest and compose this msg in an editor. >>on Thu, 04 Oct 2001 14:03:06 +0100 hans(a)beehive.de wrote >>on Zope 2.1.6 (python 1.5.2) >> >>==> Python Method Check >># no parameters, should check REQUEST.form >># and for each checked form-field add a corresponding >># diagnostic >>data = REQUEST.form >>diag = {} >>diagnose = 1 # erverything ok >> >>if data['fname' ] == '': # required >> diag.set('fname' , 'required' ) >> diagnose = 0 >>==> DTML-Document Form calls >><dtml-call "Check( ... )"> >> >>1) this is not documented in Zope Book Appendix B >>(calling DTML-Docs & DTML-Methods is documented well) >Florent Guillaume <fg(a)nuxeo.com> 4 Oct 2001 13:52:09 GMT > >You could use context.REQUEST in the python script here. > Well, i did already. Zope gave Error Type: NameError Error Value: context Ugly, isn't it? Maybe, zope 2.1.6 itself is buggy there The historic Zope 2.1.6 is also remote, no access to sources.

I'm amazed how well it has improved compared to my memory. I will read it again once i find the time. Still, im wondering why REQUEST was called instead of just passed as parameter, and is there a way to avoid the calling of (a callable REQUEST)?

Hi, Does somebody knows a direct link to an howto which shows how I can show my own wikis with the same header and footer of my site? I've tried to search for this on zope.org... but all searches with ZWiki or Wiki in it return a lot of results... Thanks in advance, Tom.

Hi there This page: http://www.webdav.org/projects/ still contains this link: Zope: http://webdav.zope.org/ See the test server homepage for details but it seems the target page has gone away. Is it available elsewhere? Should the link be taken down? Regards, Jean Jordaan

roxen with zope
by Justin Heesemann 05 Oct '01

05 Oct '01

Hi... on my way testing roxen i was wondering how i could use zope + virtualhostmonster with it. I was using apache with a rewrite rule RewriteRule ^/(.*) http://localhost:8080/VirtualHostBase/http/www.test.com:80/test.com/Virtual… [P] and i tried to do the same thing in roxen, adding the http relay module to a site and set a relay pattern: MATCH ^/(.*) CALL http://localhost:8080/VirtualHostBase/http/www.test.com:80/test.com/Virtual… which should to the same in my opinion. Well.. it doesn't. Pointing my browser to www.test.com i'll end up with getting nothing, the browser trying all the time to open something but it never gets an answer. roxen says, it got a request which matched the regex ^/(.*) but it doesn't seem to successfully connect to zope. Any suggestions ? Best Regards, Justin
