Hi all. We're trying to tackle a problem in hanging connections in ZPsycopg. 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 ;)) 2) where is the code which handles the caching of the objects? 3) is it possible to disable caching of some object? 4) when an _v_ attribute is removed, what code of the object/attribute itself is called? If possible, please answer also directly to me (I'm not on this list). Regards Marco -- Marco Bizzarri - Amministratore Delegato - Icube S.r.l.
