RE: [Zope] RAM cache invalidation - resolved
by Rauch, Juergen (Juergen) 21 Apr '04

Jonathan, you were pointing into the right direction. I wrote an external function like this: def invalidateAll( aCacheMgr, ob): aCacheMgr.ZCacheManager_getCache().ZCache_invalidate(ob) return "data has been invalidated" and I use it in a dtml-document like this: <dtml-var expr="invalidateAll( myRAMCacheManager, folderInWhichTheCashedObjectsReside )"> This seems to do the job. cheerio, Juergen -----Original Message----- From: zope-bounces(a)zope.org [mailto:zope-bounces@zope.org] On Behalf Of Rauch, Juergen (Juergen) Sent: 20 April 2004 17:22 To: zope(a)zope.org Subject: RE: [Zope] RAM cache invalidation Jonathan, I don't see how this can be done. I am using the Standard RAM Cache manager to cache the results of a couple of scripts(python). I am not writing a new Product, just using zope default components. All I want to do is invalidate all cashed results let's say with a single mouse click. The purpose of this is to give the user a possibility to refresh the view whenever he wants to. This means in between the Cache Managers cleanup_interval. May be a way to achieve this would be to set the cleanup_interval to 0 and then back to the original value. But this seems to be also a kind of sick, if it will work at all.

If you are working with python products/external methods to implement your application, could you subclass your RAM cache manager to get access to the 'manage_cacheGC' utility?

How to set a cookie on two different domains at login time in one of them?
by Gregoire Weber 21 Apr '04

21 Apr '04

Hi all! I'd like to log in into e.g. 'www.example.com' and beeing automatically logged in in 'www.example.org' also (pages from www.example.com link to www.example.org) I'd like to copy the cookie for 'www.example.com' also in 'www.example.com'. Details: So if somebody logs in by filling out the www.example.com/site/login_form calling the www.example.com/site/login script I'd like the user also beeing logged in automatically into www.example.org/site (has a login script also). I must admit, that the sites are Plone sites but it seems independent of that. In the root there is a CookieCrumbler and Plone uses Cookies also. I tried to read the '__ac' and '__ac_name' cookies from within www.example.com/site/login but they're not available. Got they eaten by the CookieCrumbler? I see them in the browsers Cookie management screen. If I could access them I could redirect to www.example.org/site/login with the login information automatically and then redirect back to www.example.com/site/logged_in or something similar. Does somebody have a solution or an idea? Gregoire

Question about application design
by Robb Shecter 21 Apr '04

21 Apr '04

Hi, I'm not sure how to do my current project in a Zope environment: It's something like a trip planner that computes an itinerary. Pretty simple use case actually - the user submits origin and destination, and potential trip plans are returned. BUT: What I want to do is keep the data structure in memory. Right now, I have this written as a standalone Python app that creates all the objects it needs, and then uses an algorithm to find the shortest path. This is the typical application server scenario: I want the Python classes to only do the startup work once, and then just answer requests which run an algorithm over the data. But how to do this with Zope? As far as I can tell, the Python Scripts are stateless. The only idea I've had so far is to make my Python app into a standalone server which answers requests via XML-RPC. Then Zope stands between it and the user. But is there any way to use just Zope, and not maintain my own server too? Thanks! Robb
