[Zope-dev] more than one user: zope 'hangs'
Hello, We have got a funny problem in Zope: if user A issues a long-running query user B also has to wait in the meantime - zope just waits for A's query to finish. We are using interbase as our database and GV Interbase Database Adapter 0.9.6 on a linux system. In the README it says 'threadsafety ... is set to 1 - threads may share the module but not connections' Somehow i suspect the problem lies there. Can anyone give me a hint on this problem?

Stephan, This likely means that the interbase database adapter essentially serializes access to the database. You may want to try sending a mail to the DA maintainer if he is not on the list...

Bob's original design made gvibDA use ThunkedTM So I believe it is serialized. I think the reason for using Thunked was because under Windows, gds is not truly multi-threaded and dies. I do not recall exactly what the story is.. You're welcome to try it without the Thunked Mixin.
