Re: [Mod_python Wiki] Update of Session use with classes by MartinStoufer
Don't use MemorySession in the example as it will only work on Windows
and will not work on multi process MPMs on UNIX as each process will
have its own session database instance in its local memory. The
MemorySession
also will not work across Python interpreter instances.
Thus, suggest start out by allowing default session type for platform
to be used.
Session types can be talked about later or in a separate example.

A good start.

Using this PythonOption session as an example, we actually have 3 different cases: Version 3.1.4 PythonOption session is not used. When calling Session.Session(req) you get the default session type for your platform: DbmSession with the prefork-mpm and worker-mpm, MemorySession with the winnt-mpm. Version 3.2 PythonOption session was introduced to allow the default session type to be overridden at run time. Version 3.3 (real soon now) We started using PythonOption much more heavily in 3.2 to control the run time configuration of mod_python. It quickly became apparent that the potential for key conflicts with user code was rather high, so for 3.3 we adopted a new PythonOption namespace. Thus PythonOption session has been deprecated in favour of PythonOption mod_python.session.session_type. So my question is How do we handle this in general?. At the very least any of the Wiki authors should note which version of mod_python they used when creating their examples. Jim
