I expect, you have somehow broken the acquisition chain. Does your product inherits "Acquisition.{Ex|Im}plicit" or at least "ExtensionClass.Base"? If not, Zope's permission machinery will not work.

Compiling new Splitter.c on Windows
by Big John Holmes 27 Mar '01

27 Mar '01

Howdy all. It's been a while since I've posted because the company I used to work for is sliding into the sludge. So I'm working on my own now! Unfortunately that means I have to use Windows with Zope. Since I have no experience in this area I'll cut to the chase. I have aSplitter.c file written that works under linux, and I'd like to use it under Windows. How do I do it. I tried compiling the source distribution off Zope.org, but wo_pcgi.py starts and dies. What's the secret? All my best, Jason Spisak __________________________________________________ Do You Yahoo!? Get email at your own domain with Yahoo! Mail. http://personal.mail.yahoo.com/

More Core Session Tracking Woes :-(
by Chris Withers 26 Mar '01

26 Mar '01

Hi, The setup: -Zope 2.2.4 -Core Session Tracking 0.7 -Cookie session ID manager (path=/,lifetime=0) -Internal Session Data Manager (timeout set to 60 minutes) This seems to randomly (but sometimes very frequently) loose session data items :-( I've sprayed lots of log statements around (including in SessionData.invalidate, to ensure I wasn't inadvertently calling it) and so far it appears that the session id cookie is being returned by the browser (so path, lifetime, etc are probably okay) but self.session.getSessionData().get('Type','') is often returning an empty string, even when I know it has been set. This is an intermittent problem though, so it's probably going to be a bitch to track down :-( There's doesn't seem to be any correlation with the 'Can't Load State for x' problem I reported earlier, but I guess it could be the same thing. Anyway, please help, I'm loosing (hair|sleep|etc) over this :-( cheers, Chris

FastCGI question
by sam gendler 26 Mar '01

26 Mar '01

I haven't used Zope to any significant degree in over a year. When I was last using Zope regularly, FastCGI still had some stability issues, which made it difficult to use in a production environment. However, I have always felt that FastCGI was the better solution when choosing between proxy, pcgi and fastcgi, from a theoretical standpoint. Can someone comment as to the efficacy of using FastCGI to implement an interface between my HTTP enabled application and current version of Zope, or should I use one of the other solutions. --sam -- ---------------------------------------------------- "Nobody looks good with brown lipstick on." --Frank Zappa

Core Session Tracking Problem?
by Chris Withers 26 Mar '01

26 Mar '01

I've been noticing these sorts of messages in a number of our server logs: 2001-03-26T12:56:19 ERROR(200) ZODB Couldn't load state for '\000\000\000\000\000\002\030\316' Traceback (innermost last): File /mnt/data/2/zope/2-2-4_base/lib/python/ZODB/Connection.py, line 443, in setstate AttributeError: 'None' object has no attribute 'load' I think I posted about it a while back, but I've started to notice that these only occur in applications where wer'e using the Core Session Tracking product. Given the low OID numbers, it does sound like it's something in the funky RAM based session that's not being found, but I may be talking rubbish ;-) Anyway, it occurs on Zope 2.2.4, 2.2.5, and 2.3.xbx. Do core session tracking bugs go in the collector or somewhere else? cheers, Chris

Determining Acquired Permissions?
by richard＠bizarsoftware.com.au 26 Mar '01

26 Mar '01

RoleManager doesn't seem to offer any way to determine what permissions are acquired for roles. If I'm wrong, please quietly direct me to the appropriate API call :) If I'm not, I need to know how to determine this information. We're using a simplified interface to access controls in our management screens, and we need to be able to display exactly what the permissions are at a given point in the object tree. I honestly believe that RoleManager should do the same thing, but that's possibly the subject of another email :) I'm about to use a custom method which walks aq_chain (yay for aq_chain :) looking for _View_Permission ('View' being the permission I'm interested in). What are the chances this will break in the future - the attribute has a leading underscore and therefore is private as far as I'm concerned. Naughty Richard, but he can't find another way...
