Within the mod_python.apache module there exists two private variables called "_server" and "_interpreter". These are initialised when an interpreter is first created. The variables are set to be an instance of the mod_python "serverobject" and the name of the interpreter. In effect, these would be the same as are available to a request handler as "req.server" and "req.interpreter".
The problem with those in the "req" object is that they are only available to the request handler. If these variables in the "mod_python.apache" module are made part of the public API, they would then be accessible by any code. Since "server.get_options()" now exists and "server.get_config()" works properly, making these public would allow code running at global scope when a module is being imported to consult the server level config and/or options to customise their runtime behavour.
Thus, proposed that these variables be renamed to "apache.server" and "apache.interpreter".
