This is a huge set of changes, that touches almost all of the files. I'm sure I have broken quite a bit, but better to take the plunge now than to postpone this until later. The idea is to allow for pluggable backends throughout the code. Brief Overview For compute/volume/network, there are multiple classes service - responsible for rpc this currently uses the existing cast and call in rpc.py and a little bit of magic to call public methods on the manager class. each service also reports its state into the database every 10 seconds manager - responsible for managing respective object classes all the business logic for the classes go here db (db_driver) - responsible for abstracting database access driver (domain_driver) - responsible for executing actual shell commands and implementation Compute hasn't been fully cleaned up, but to get an idea of how it works, take a look at volume and network Known issues/Things to be done: * nova-api accesses db objects directly It seems cleaner to have only the managers dealing with their respective objects. This would mean code for 'run_instances' would move into the manager class and it would do the initial setup and cast out to the remote service * db code uses flat methods to define its interface In my mind this is a little prettier as an abstract base class, but driver loading code can load a module or a class. It works, so I'm not sure it needs to be changed but feel free to debate it. * Service classes have no code in them Not sure if this is a problem for people, but the magic of calling the manager's methods is done in the base class. We could remove the magic from the base class and explicitly wrap methods that we want to make available via rpc if this seems nasty. * AuthManager Projects/Users/Roles are not integrated into this system. In order for everything to live happily in the backend, we need some type of adaptor for LDAP * Context is not passed properly across rabbit Context should probably be changed to a simple dictionary so that it can be passed properly through the queue * No authorization checks on access to objects We need to decide on which layer auth checks should happen. * Some of the methods in ComputeManager need to be moved into other layers/managers * Compute driver layer should be abstracted more cleanly * Flat networking is untested and may need to be reworked * Some of the api commands are not working yet * Nova Swift Authentication needs to be refactored(Todd is working on this)	Vishvananda Ishaya	14 years ago
