sesspy Description

sesspy is a session/transaction management and dependency injection library.ConceptsA primary concept is that of a session factory. A session factory is a callable that returns a thread‐local Session object. Examples of session factories include:- the SessionFactory class- the ComponentRef classThe resulting Session object is, as mentioned, thread‐local. The existence of a Session object does not imply that a session has been opened. To access a session for the target resource, the Session.open method must be called, and will return an object for the session. Committing or aborting the session must also be done via the Session object. The Session object can also be used as a guard in a with statement.A source is any object capable of opening sessions or connections, i.e. an interface to resources. To convert a source into a format useable by sesspy, various helpers can be found with the source module. In particular, SourceAdapter (and its wrappers source_adapter_factory and sessionless_source_adapter) can be used to supply open, commit and abort methods used by sesspy.Product's homepage
