Re: [Zope-dev] SAP SSO feature for Zope/LDAPUserFolder
Dirk Datzert wrote: Hi, we have Zope 2.6.4 and 2.7.6 with LDAPUserFolder and CookieCrumbler in use. One of our next goals is to integrate the Single-Sign-On-Ticket feature of SAP-Portal. SAP sent a cookie called MYSAPSSO2 which contains a certified signature and the Login-Name of a user. Normally the Login-Name will be validated by LDAPUserFolder with password against LDAP-Directory and the roles of the user will be assigned to the user object. We have now an external web-service which can validate the MYSAPSSO2-Ticket and return the Login-Name. I'm looking now for the best way to integrate/rewrite CookieCrumbler/LDAPUserFolder to take the validated Login-Name and read the roles of the user out of the LDAP-directory. Any ideas ? Maybe comments by Jens or Shane ? Regards, Dirk I'm not sure this could work for you... I've tried integrating Zope with an SSO system, which did not provide any authentication other than setting a correct REMOTE_USER in the REQUEST (we did it behind Apache). We succeded by subclassing CookieCrumbler so that it was able to deal with those situations. Also, we were working with Zope in Remote User Mode. I can provide the code, if necessary.

[Zope-dev] Access to global methods in product creation forms
Hi all. I would like to use a global method in the add form of a product. I've declared the method in the methods dictionary of the package. However, when I try to add the product, I receive an unauthorized exception. The environment is python2.3.4 and zope 2.7.3, running on Debian GNU/Linux. I've attached a simple test product showing the problem. Thanks you in advance for your support.

This is better done in a transcation-hooking type way, a la CTM.py in ZOracleDA... cheers, Chris I'm trying something inspired to that at the moment... I succeeded in installing an hack, very inspired from your code (but at a much simpler level) and some code in the SecurityManager, where I mantain a dictionary of connections, indexed by the result of thread.get_ident(). Once a thread needs a new connection, either it is present in the dictionary or not. If it is present, give it to the thread and assign that to the _v_database_connection attribute. Otherwise, create a new one, put in the dictionary, and go on as before. Of course this is a (horrible) hack, because if you have more than one ZPsycopg objects you will end with mixed connections (argh!) As a proof of concept however it works, and it is resistent to the refreshing of other products (not the ZPsycopg one).

No, but you can (in most cases) flush it again by calling its _p_deactivate method. You can always do it by assigning None to _p_changed, but this is highly unsafe. You should not do it (unless you really know what you are doing). Another was of saying this is that the cache performs an important role in maintaining object identity. It's not possible to use a persistent object without using a cached version of it. If you think you need to disable caching, you should probably say something more about what you are trying to do. 4) when an _v_ attribute is removed, what code of the object/attribute itself is called? The object's __del__ method (if defined). This means the object that was bound to the _v_ attribute not the object that had the _v_attribute. The setattr hook in cPersistence.c is called when an attribute is removed (del obj.attr). An __del__() method would only be called if the last reference to the object was also deleted. And __del__ is to be avoided whenever possible. What I would like to do is to have an hook to the removal of a _v_ attribute, so that I can perform some action *BEFORE* losing any reference to the object itself. I look at the setattr code in cPersistence.c and tried also to write my own __setattr__, but I do not know what should be called *AFTER* my code. What I would do is: def __setattr__(self, key, value): if key[0:3] == '_v_': doMyStuff() doStandardStuff() but I do not know what doStandardStuff actually is.

Hehe, I fixed this for ZOracleDA a couple of months ago. You may want to look at the thread pool code in there to see how I did it, gimme a nod if you need a URL (it's on a CVS branch in cvs.zope.org) I took a look at that, the connections.CTM, and the other. The simple question is if this is a known problem with *ALL* db adapters, and, in this case, it could be possible to devise a general solution, or if this has something to do with psycopg. I've a scenario where I can produce hanging connections in ZPsycopg: 1) use page with sql methods 2) refresh a product 3) repeat 1) 4) refresh a product if you have 4 threads, you should have now 5 connections. Obviously here there is something wrong with the management of _v_ attributes, in particular the _v_database_connection in the DA.py. The psycopg code is quite similar to the basic DA.py code, so I was looking for other ways of approaching the problem. However, I would like to have some information about the functioning of the _v_ attributes, and the cache management. In particular: 1) where is the code which handles the _v_ attributes (I like to look at the source code, you know ;)) Never bothered finding it, the sematics are pretty well documented. Yes, actually. 2) where is the code which handles the caching of the objects? The ZODB cache. It's big and complicated, trust me, you DON'T need to go there... :( 3) is it possible to disable caching of some object? No. The fact that you want to means you're mis-using _v_ attributes ;-) My feeling was that the hanging connection problem was related to the cache... so the question (I'm not using _v_ attributes in any particular way) 4) when an _v_ attribute is removed, what code of the object/attribute itself is called? None. I believe it gets lost at the object is ghosted. If possible, please answer also directly to me (I'm not on this list). Are you maintaining ZPsychopg? If not, the maintainers might be able to help... No, actually we've a db application which makes a lot of use of zpsycopg for insert/updates, not only for select, and we stumbled on this problem. We're working with Federico Di Gregorio (psycopg mantainer) in order to solve the problem. cheers, Chris - who learnt a whole lot more about ZODB and ZODB caching when solving this kind of problem in ZOracleDA ;-) I suspect I will have to learn something in the hard way too :) -- Simplistix - Content Management, Zope Python Consulting - http://www.simplistix.co.uk Thanks for your help Regards Marco -- Marco Bizzarri - Amministratore Delegato - Icube S.r.l.
