[Zope-dev] LoginManager ownership bug!

[Jonas Juselius]

Cheers!

I actually tried to implement support for local roles in almost exactly the 
same way as you did, but for some reason I didn't get it to work. 
Perhaps I should look into the matter again... I just threw in the 
user_names(), and getUserNames() into the LoginManager, added some dtml to
handle SQL and... it didn't work, so I dropped it... ;-) I'll try to come up
with some nice way to handle local roles in a proper way in the LoginManager,
and hope that I get my patches accepted :-)

Do you have any clue about the ownership bug in the LoginManager? I find it
quite strange that an unowned object becomes owned whenever Zope is restarted
(or when a method is added...). I suspect that the problem is within the
ZPatterns modules, since it handles the persistance of the LoginManager...
This is how the LoginManager is inited and ownership is set:

ob=LoginManager()
ob._owner=UnownableOwner
self._setObject('acl_users', ob)

I tried to make _owner a global attribute of the LoginManager, but that didn't
solve the problem. I have also written Ty Sarna, but I have not received any
response yet.

One more thing... I'm new to PythonMethods, and I would like to know how to
get access to the self attirbute (or the DTML namespace if you like) from
PythonMethods. I would like to use PythonMethods more, beacuse dtml quickly
becomes unreadable and ugly, and Python is always beautiful :-) 

Have a nice day,
                 .jonas.
